Association and causal mediation between marital status and depression in seven countries.

Depression represents a significant global public health challenge, and marital status has been recognized as a potential risk factor. However, previous investigations of this association have primarily focused on Western samples with substantial heterogeneity. Our study aimed to examine the association between marital status and depressive symptoms across countries with diverse cultural backgrounds using a large-scale, two-stage, cross-country analysis. We used nationally representative, de-identified individual-level data from seven countries, including the USA, the UK, Mexico, Ireland, Korea, China and Indonesia (106,556 cross-sectional and 20,865 longitudinal participants), representing approximately 541 million adults. The follow-up duration ranged from 4 to 18 years. Our analysis revealed that unmarried individuals had a higher risk of depressive symptoms than their married counterparts across all countries (pooled odds ratio, 1.86; 95% confidence interval (CI), 1.61-2.14). However, the magnitude of this risk was influenced by country, sex and education level, with greater risk in Western versus Eastern countries (ß = 0.36; 95% CI, 0.16-0.56; P < 0.001), among males versus females (ß = 0.25; 95% CI, 0.003-0.47; P = 0.047) and among those with higher versus lower educational attainment (ß2 = 0.34; 95% CI, 0.11-0.56; P = 0.003). Furthermore, alcohol drinking causally mediated increased later depressive symptom risk among widowed, divorced/separated and single Chinese, Korean and Mexican participants (all P < 0.001). Similarly, smoking was as identified as a causal mediator among single individuals in China and Mexico, and the results remained unchanged in the bootstrap resampling validation and the sensitivity analyses. Our cross-country analysis suggests that unmarried individuals may be at greater risk of depression, and any efforts to mitigate this risk should consider the roles of cultural context, sex, educational attainment and substance use.

Inequalities in oral health: estimating the longitudinal economic burden of dental caries by deprivation status in six countries.

BACKGROUND: The recent World Health Organization (WHO) resolution on oral health urges pivoting to a preventive approach and integration of oral health into the non-communicable diseases agenda. This study aimed to: 1) explore the healthcare costs of managing dental caries between the ages of 12 and 65 years across socioeconomic groups in six countries (Brazil, France, Germany, Indonesia, Italy, UK), and 2) estimate the potential reduction in direct costs from non-targeted and targeted oral health-promoting interventions. METHODS: A cohort simulation model was developed to estimate the direct costs of dental caries over time for different socioeconomic groups. National-level DMFT (dentine threshold) data, the relative likelihood of receiving an intervention (such as a restorative procedure, tooth extraction and replacement), and clinically-guided assumptions were used to populate the model. A hypothetical group of upstream and downstream preventive interventions were applied either uniformly across all deprivation groups to reduce caries progression rates by 30% or in a levelled-up fashion with the greatest gains seen in the most deprived group. RESULTS: The population level direct costs of caries from 12 to 65 years of age varied between US10.2 billion in Italy to US$36.2 billion in Brazil. The highest per-person costs were in the UK at US$22,910 and the lowest in Indonesia at US$7,414. The per-person direct costs were highest in the most deprived group across Brazil, France, Italy and the UK. With the uniform application of preventive measures across all deprivation groups, the greatest reduction in per-person costs for caries management was seen in the most deprived group across all countries except Indonesia. With a levelling-up approach, cost reductions in the most deprived group ranged from US$3,948 in Indonesia to US$17,728 in the UK. CONCLUSION: Our exploratory analysis shows the disproportionate economic burden of caries in the most deprived groups and highlights the significant opportunity to reduce direct costs via levelling-up preventive measures. The healthcare burden stems from a higher baseline caries experience and greater annual progression rates in the most deprived. Therefore, preventive measures should be start early, with a focus on lowering early childhood caries and continue through the life course.

Determinants of sodium intake knowledge and attitude: a cross-national analysis of socio-economic and health factors.

OBJECTIVE: The aim of this study is to conduct a comparative analysis across nations to: (1) identify the determinants influencing knowledge and attitudes related to sodium (Na) intake and (2) to analyse the association between knowledge and attitudes related to Na intake. DESIGN: We utilised a secondary data from a cross-sectional study that was conducted across seven nations. Structural equation modelling (SEM) was utilised to assess the impact of socio-economic and health-related predictors on knowledge and attitudes pertaining to Na intake and further to investigate the relationship between knowledge and attitude. SETTING: Indonesia, Brazil, Thailand, Japan, France, the UK and the USA. PARTICIPANTS: 7090 participants aged 15 years and above were included in the study. RESULTS: SEM analysis showed a strong association between knowledge about Na intake and related attitude across all countries, particularly in the UK (2·65, 95 % CI 1·48-3·82), France (2·62, 1·45-3·79) and the USA (1·97, 1·21-2·73). In Brazil, Japan and France, individuals or family members having certain health conditions such as raised blood pressure, heart diseases, strokes or other diseases exhibited a positive attitude towards reducing Na intake. Conversely, socio-economic factors like education and income demonstrated the complexity of influences on knowledge and attitudes about Na intake. CONCLUSION: The study underscores the need for tailored public health interventions to reduce excessive Na consumption, considering the diverse cultural, social and economic factors. It highlights the complex determinants of knowledge and attitudes towards Na intake, calling for further research in varied populations.

Global potential for natural regeneration in deforested tropical regions.

Extensive forest restoration is a key strategy to meet nature-based sustainable development goals and provide multiple social and environmental benefits1. Yet achieving forest restoration at scale requires cost-effective methods2. Tree planting in degraded landscapes is a popular but costly forest restoration method that often results in less biodiverse forests when compared to natural regeneration techniques under similar conditions3. Here we assess the current spatial distribution of pantropical natural forest (from 2000 to 2016) and use this to present a model of the potential for natural regeneration across tropical forested countries and biomes at a spatial resolution of 30 m. We estimate that an area of 215 million hectares-an area greater than the entire country of Mexico-has potential for natural forest regeneration, representing an above-ground carbon sequestration potential of 23.4 Gt C (range, 21.1-25.7 Gt) over 30 years. Five countries (Brazil, Indonesia, China, Mexico and Colombia) account for 52% of this estimated potential, showcasing the need for targeting restoration initiatives that leverage natural regeneration potential. Our results facilitate broader equitable decision-making processes that capitalize on the widespread opportunity for natural regeneration to help achieve national and global environmental agendas.

Development and validation of Competing Sentence Test in Kannada.

PURPOSE: The main objective was to develop and validate a MATLAB-based Competing Sentence Test (CST-K) and obtain preliminary normative data for this test within a small cohort of children aged 8 to 12. METHODS: This study comprised two phases. Phase 1 involved developing and validating the Competing Sentence Test in Kannada (CST-K). Sentences were selected from Kannada academic textbooks of III and IV standards, recorded by a male native Kannada speaker, and evaluated by three experienced audiologists. Phase 2, which includes normative pilot estimation, was conducted on 60 right-handed children aged 8-12 without hearing difficulties. The CST-K was administered in a quiet room in the school, where the noise level ranged from 40.3 to 43.2 dBA using a laptop and soundcard, presenting thirty pairs of simple sentences with a signal-to-competition ratio of -15 dB. Test-retest reliability was assessed after three weeks. Participants were evenly distributed among four age groups: 8-8.11 years, 9-9.11 years, 10-10.11 years, and 11-11.11 years. RESULTS: The results indicated a significant difference between the scores obtained for the right and left ears. There was also a statistically significant difference across the age groups. The test-retest reliability test showed excellent reliability for the right ear and good reliability for the left ear scores. CONCLUSION: A MATLAB-based Competing Sentence Test in Kannada Language was developed and validated in a recent study. The study found that scores were higher for the right ear and there was a significant age-related difference. This test can be used to evaluate binaural separation skills in Kannada-speaking children and can be included in the test battery. The study also provides normative data for the competing sentence test, which is reliable, making it a unique tool for clinicians to assess various clinical populations.

Analysis of factors associated with public attitudes towards salt reduction: a multicountry cross-sectional survey.

OBJECTIVE: This paper provides an in-depth examination of public attitudes towards salt reduction across seven culturally diverse countries: the USA, the UK, France, Japan, Indonesia, Thailand, and Brazil. DESIGN: Cross-sectional regression analysis with questionnaire data. SETTING: An analysis of questionnaire study in seven countries. PARTICIPANTS: The study's questionnaire collected responses from 7090 participants across seven countries with the mean age of respondents being 46.06 years (SD 16.96). The gender distribution encompassed 3473 men (49.12%), 3582 women (50.66%), 24 non-binary individuals (0.34%) and 11 who identified as 'other' (0.16%). PRIMARY AND SECONDARY OUTCOME MEASURES: Attitudes toward sodium reduction were measured on a seven-point Likert scale. RESULTS: Regression analysis revealed significant associations between attitudes towards sodium reduction and various factors across countries. Gender was a significant factor in France, with women showing less awareness than men (coefficient -0.123, 95% CI -0.237 to -0.008). Age was a significant factor in Japan and Thailand, with older generations exhibiting stronger awareness. Occupation was a significant factor in France (grocery, 0.678, 0.229 to 1.127) and Japan (food service, 0.792, 0.300 to 1.283). In France (0.090, 0.033 to 0.146) and Brazil (0.092, 0.040 to 0.144), attitudes towards reducing sugar intake were positively associated with sodium reduction attitudes. Government interventions showed varying impacts, with positive associations in Thailand (0.004, 0.001 to 0.008) and negative associations in France (-0.003 -0.005 to -0.000). CONCLUSION: Our study reveals a complex array of factors shaping attitudes towards sodium reduction across seven countries. These findings support the need for nuanced, country-specific approaches in formulating sodium reduction strategies. Future research should validate these findings, explore further determinants and understand how attitudes translate into dietary behaviours.

Isolation and identification of plant growth-promoting rhizobacteria from Spinifex littoreus in Parangkusumo Coastal Sand Dunes, Indonesia.

Utilizing coastal land for agriculture presents challenges such as low water content, high soil salinity, and low organic compound content. To support plant growth under these conditions, biofertilizers composed of plant growth promoting Rhizobacteria (PGPR), especially those inhabiting coastal areas, are needed. The Parangkusumo sand dunes on the southern coast of Java, Indonesia, is a unique coastal ecosystem characterized by arid conditions, high temperatures, and high soil salinity. To date, no studies have reported the isolation of PGPR from this ecosystem. This study is the first to isolate and identify PGPR associated with Spinifex littoreus, a dominant plant species in the Parangkusumo sand dunes, which are adapted to the harsh condition of Parangkusumo sand dunes. Ten rhizobacterial isolates were obtained, with five identified as members of the Bacillaceae family. All isolates demonstrated phosphate solubilization activity, while seven exhibited cellulolytic activity. One isolate, Priestia aryabhattai strain 2, notably showed phosphate solubilization and nitrogen fixation activities. The findings of this PGPR activity screening offer valuable insights for developing biofertilizers tailored for coastal agricultural applications.

Molecular identification of new Trypanosoma evansi type non-A/B isolates from buffaloes and cattle in Indonesia.

Trypanosoma evansi is reportedly divided into two genotypes: types A and B. The type B is uncommon and reportedly limited to Africa: Kenya Sudan, and Ethiopia. In contrast, type A has been widely reported in Africa, South America, and Asia. However, Trypanosoma evansi type non-A/B has never been reported. Therefore, this study aims to determine the species and genotype of the Trypanozoon subgenus using a robust identification algorithm. Forty-three trypanosoma isolates from Indonesia were identified as Trypanosoma evansi using a molecular identification algorithm. Further identification showed that 39 isolates were type A and 4 isolates were possibly non-A/B types. The PML, AMN-SB1, and STENT3 isolates were likely non-A/B type Trypanosoma evansi isolated from buffalo, while the PDE isolates were isolated from cattle. Cladistic analysis revealed that Indonesian Trypanosoma evansi was divided into seven clusters based on the gRNA-kDNA minicircle gene. Clusters 6 and 7 are each divided into two sub-clusters. The areas with the highest genetic diversity are the provinces of Banten, Central Java (included Yogyakarta), and East Nusa Tenggara. The Central Java (including Yogyakarta) and East Nusa Tenggara provinces, each have four sub-clusters, while Banten has three.

The Association Between Depressive Symptoms, Access to Diabetes Care, and Glycemic Control in Five Middle-Income Countries.

OBJECTIVE: The relationship between depression, diabetes, and access to diabetes care is established in high-income countries (HICs) but not in middle-income countries (MICs), where contexts and health systems differ and may impact this relationship. In this study, we investigate access to diabetes care for individuals with and without depressive symptoms in MICs. RESEARCH DESIGN AND METHODS: We analyzed pooled data from nationally representative household surveys across Brazil, Chile, China, Indonesia, and Mexico. Validated survey tools Center for Epidemiologic Studies Depression Scale Revised, Composite International Diagnostic Interview, Short Form, and Patient Health Questionnaire identified participants with depressive symptoms. Diabetes, defined per World Health Organization Package of Essential Noncommunicable Disease Interventions guidelines, included self-reported medication use and biochemical data. The primary focus was on tracking diabetes care progression through the stages of diagnosis, treatment, and glycemic control. Descriptive and multivariable logistic regression analyses, accounting for gender, age, education, and BMI, examined diabetes prevalence and care continuum progression. RESULTS: The pooled sample included 18,301 individuals aged 50 years and above; 3,309 (18.1%) had diabetes, and 3,934 (21.5%) exhibited depressive symptoms. Diabetes prevalence was insignificantly higher among those with depressive symptoms (28.9%) compared with those without (23.8%, P = 0.071). Co-occurrence of diabetes and depression was associated with increased odds of diabetes detection (odds ratio [OR] 1.398, P < 0.001) and treatment (OR 1.344, P < 0.001), but not with higher odds of glycemic control (OR 0.913, P = 0.377). CONCLUSIONS: In MICs, individuals aged 50 years and older with diabetes and depression showed heightened diabetes identification and treatment probabilities, unlike patterns seen in HICs. This underscores the unique interplay of these conditions in different income settings.

Sumbawa cattle: a study of growth hormone (GH) gene variants and their association with biometric traits.

The growth hormone (GH) gene plays a vital role in regulating animal metabolism and body size, making it a potential candidate for influencing livestock performance. This study aimed to investigate the polymorphisms within the GH gene and their associations with 10 biometric traits in the Sumbawa cattle population of Indonesia. Biometric trait data and blood samples were collected from 112 Sumbawa cattle individuals, and their GH gene sequences were analyzed using two sets of primers for amplification. Seven single nucleotide polymorphisms (SNPs) were identified in the GH gene: g.442C>T, g.446G>C, g.558C>T, g.649C>A, g.1492C>A, g.1510C>A, and g.1578G>A. All SNPs were located in the intronic region except for SNP g.558C>T, which was found in the coding sequence (CDS) region. The SNP g.558C>T is classified as a synonymous variant. Haplotype analysis revealed a strong linkage disequilibrium between SNPs g.558C>T and g.649C>A. Distributions of genotypes and alleles of all SNPs were in agreement with the Hardy-Weinberg equilibrium (p > 0.05, χ2 < 15.56), except for SNPs g.446G>C and g.1492C>A. The association study showed that the SNP g.442C>T significantly (p < 0.05) affected HL, BL, SH, and PH traits in Sumbawa cattle. Additionally, the g.446G>C and g.558C>T were also found to be associated with PH and CC traits, respectively. The polymorphisms detected in the GH gene could have implications for selection programs to enhance desired biometric traits in Sumbawa cattle. Improving livestock productivity can be done by understanding genetic diversity and its relationship with phenotypic characteristics.

Maternal and child oral health barriers and solutions: Case studies from South Africa, Brazil, and Indonesia.

The World Federation of Public Health Associations (WFPHA) has introduced a maternal oral health framework and launched its Global Maternal and Child Oral Health Initiative, advocating for maternal and child health as a strategic entry point for oral health to be integrated into primary healthcare systems. This article delves into maternal oral health initiatives in South Africa, Brazil, and Indonesia, exploring challenges and proposing context-specific solutions aligned with the WFPHA maternal oral health framework and its Global Maternal and Child Oral Health Initiative. The apartheid legacy in South Africa has led to the gross health inequalities, including oral health disparities characterized by maldistribution of dental facilities and dental professionals in the public sector. The proposed objectives focus on effective leadership, human resource capacity building, and integration of maternal and child oral health policy into existing health policies. Brazil faces challenges in reaching pregnant women, especially pregnant teens, due to workforce shortages. Brazil's Oral Health National Program mandates all pregnant women undergo at least one dental appointment, but a shortage of oral health teams persists and impedes timely access to dental care during pregnancy. Dental students' outreach to vulnerable pregnant teens can enhance the future oral health workforce's sensitivity to maternal oral health matters. In Indonesia, the Antenatal Care Innovative (iANC) Project has introduced a co-training model for midwives and oral health professionals addressing oral health needs of mothers and their spouses and fostering a comprehensive understanding of the interplay between oral health and maternal well-being. These country cases demonstrate the importance of tailored policies, health promotion, and care delivery interventions in maternal oral health. All cases highlight the importance of workforce training and distribution, fostering cross-disciplinary collaboration and future oral health workforce who can promote health beyond treatment delivery.

Distinctive color variation in Rhinolepadichthys geminus (Gobiesocidae: Diademichthyinae) from Alor Islands, Indonesia: morphological and molecular insights.

Rhinolepadichthys geminus, one of three recently described species in the genus Rhinolepadichthys (previously known as Lepadichthys lineatus complex), is characterized by several distinct diagnostic morphological and color features, including a pair of yellow stripes on the body ventral midline. However, one of three specimens recently collected from the Alor Islands, Indonesia, possessed a yellow circular line, instead of a pair of yellow stripes, indicating that the latter were not an invariable feature. Morphological and molecular evidence confirmed the identity of the specimen and intraspecific significance of the color variation.

Nasolabial anthropometry using 3D computed tomography scan reconstruction: baseline study for nasolabial correction in Indonesian children with cleft lip and palate / Antropometría nasolabial mediante reconstrucción con tomografía computarizada 3D: estudio de referencia para la corrección nasolabial en niños Indonesios con fisura labiopalatina

Background: The normal nasolabial structure of infants and chil-dren from East Asian, specifically Indonesian, descent groups has been less explored in the literature. This anthropometric study is used as a guide in lip repair in patients with clefts. This retrospective study used archived CT images from the Indonesian population. Materials and Methods: Computed tomography records of children under 5 years of age were extracted from a provincial hospital. The images were then filtered based on the inclusion and exclusion criteria and then the 2D slices were reconstructed using the open source software Invesalius. Twenty-five variable nasolabial parameters of the nasolabial structure were then measured in the 3D rendering mode. Images with craniofacial dysmorphism or cannulas that passed over the nasolabial structure were excluded. Results were summarized using descriptive statistics. Results: Fourteen of 128 CT images were included in this study. The samples were divided into two age groups: 0-12 months and 25-54 months. There were moderate to strong, positive correlations between age and all nasolabial variables, which were statistically significant (p<0.05) except for nasal length, nares circumference, columella width, superior philtrum width, philtrum column height, and cutaneous upper lip height. Conclusions: This study described anthropometric measurements of normal nasolabial structures as a reference point for lip correction surgery. However, to obtain more accurate anthropometric guidelines, further studies with larger sample sizes are desirable. Although surgical repair of the lip is usually performed within the first year of life, some cases of surgery are performed after infancy.

Antecedentes: La estructura nasolabial normal de bebés y niños de grupos de ascendencia de Asia oriental, específicamente de Indonesia, ha sido menos explorada en la literatura. Este estudio antropométrico se utiliza como guía en la reparación del labio en pacientes con fisuras. Este estudio retrospectivo utilizó imágenes de tomografía computarizada archivadas de la población indonesia. Materiales y Métodos: Se extrajeron los registros de tomografía computarizada de niños menores de 5 años de un hospital provincial. Luego, las imágenes se filtraron según los criterios de inclusión y exclusión y luego se reconstruyeron los cortes 2D utilizando el software de código abierto Invesalius. Luego se midieron veinticinco parámetros nasolabiales variables de la estructura nasolabial en el modo renderizado 3D. Se excluyeron imágenes con dismórfica craneofacial y cánula que pasa sobre la estructura nasolabial. Los resultados se resumen mediante estadística descriptiva. Resultado: En este estudio se incluyeron catorce de 128 imágenes de TC. Las muestras se dividieron en dos grupos de edad: 0-12 meses y 25-54 meses. Hubo una correlación positiva de moderada a fuerte entre la edad y todas las variables nasolabiales, que fueron estadísticamente significativas (p<0,05) excepto la longitud nasal, la circunferencia de las narinas, el ancho de la columela, el ancho del filtrum superior, la altura de la columna del filtrum y la altura cutánea del labio superior. Conclusión: Este estudio describió las medidas antropométricas de estructuras nasolabiales normales como base para la cirugía de corrección de labios. Sin embargo, para obtener directrices antropométricas más precisas, son deseables más estudios con tamaños de muestra más grandes. Aunque la reparación quirúrgica del labio normalmente se realiza dentro del primer año de vida, en algunos casos la cirugía se realiza después de la infancia.

Climate velocities and species tracking in global mountain regions.

Mountain ranges contain high concentrations of endemic species and are indispensable refugia for lowland species that are facing anthropogenic climate change1,2. Forecasting biodiversity redistribution hinges on assessing whether species can track shifting isotherms as the climate warms3,4. However, a global analysis of the velocities of isotherm shifts along elevation gradients is hindered by the scarcity of weather stations in mountainous regions5. Here we address this issue by mapping the lapse rate of temperature (LRT) across mountain regions globally, both by using satellite data (SLRT) and by using the laws of thermodynamics to account for water vapour6 (that is, the moist adiabatic lapse rate (MALRT)). By dividing the rate of surface warming from 1971 to 2020 by either the SLRT or the MALRT, we provide maps of vertical isotherm shift velocities. We identify 17 mountain regions with exceptionally high vertical isotherm shift velocities (greater than 11.67 m per year for the SLRT; greater than 8.25 m per year for the MALRT), predominantly in dry areas but also in wet regions with shallow lapse rates; for example, northern Sumatra, the Brazilian highlands and southern Africa. By linking these velocities to the velocities of species range shifts, we report instances of close tracking in mountains with lower climate velocities. However, many species lag behind, suggesting that range shift dynamics would persist even if we managed to curb climate-change trajectories. Our findings are key for devising global conservation strategies, particularly in the 17 high-velocity mountain regions that we have identified.

The impact of international health worker migration and recruitment on health systems in source countries: Stakeholder perspectives from Colombia, Indonesia, and Jordan.

INTRODUCTION: To address domestic shortages, high-income countries are increasingly recruiting health workers from low- and middle-income countries. This practice is much debated. Proponents underline benefits of return migration and remittances. Critics point in particular to the risk of brain drain. Empirical evidence supporting either position is yet rare. This study contributes to filling this gap in knowledge by reporting high-level stakeholders' perspectives on health system impacts of international migration in general, and active recruitment of health workers in specific, in Colombia, Indonesia, and Jordan. METHOD: We used a multiple case study methodology, based on qualitative methods integrated with information available in the published literature. RESULTS: All respondents decried a lack of robust and detailed data as a serious challenge in ascertaining their perspectives on impacts of health worker migration. Stakeholders described current emigration levels as not substantially aggravating existing health workforce availability challenges. This is due to the fact that all three countries are faced with health worker unemployment grounded in unwillingness to work in rural areas and/or overproduction of certain cadres. Respondents, however, pleaded against targeting very experienced and specialised individuals. While observing little harm of health worker migration at present, stakeholders also noted few benefits such as brain gain, describing how various barriers to skill enhancement, return, and reintegration into the health system hamper in practice what may be possible in theory. CONCLUSION: Improved availability of data on health worker migration, including their potential return and reintegration into their country of origin's health system, is urgently necessary to understand and continuously monitor costs and benefits in dynamic national and international health labour markets. Our results imply that potential benefits of migration do not come into being automatically, but need in-country supportive policy and programming, such as favourable reintegration policies or programs targeting engagement of the diaspora.

Disclosure of genetic diversity of mackerel fish (Scomberomorus spp.) in Indonesian waters based on the mitochondrial cytochrome oxidase subunit II (COII) gene.

Mackerel fish (Scomberomorus spp.) represents a significant marine fisheries commodity in Indonesia, characterized by its high commercial value and nutritional content. To understand the intraspecific interactions and genetic variability of Scomberomorus spp., a more extensive research of Scomberomorus spp. populations, including both cultivated and wild specimens, is required. This study aimed to explore the genetic diversity of mackerel fish in Indonesian waters, focusing on the mitochondrial DNA (mtDNA) cytochrome oxidase subunit II (COII) gene, which encodes the second subunit of cytochrome c oxidase (complex IV), is essential for aerobic respiration and energy transformation. Muscle tissue samples from 18 individual mackerel fish collected from various regions in Indonesia, including Palembang, Cilacap, Rembang, Banjarmasin, Ambon, and Fak-Fak Regencies, were utilized. The genomic DNA was isolated and amplified using specific primers: CO2TF (5'-ACCGCTCTGTCACTTTCTTC-3') and CO2TR (5'-ATGTCACTAAGGGTGGTTGG-3'). Subsequently, the obtained amplicons were subjected to sequencing. The sequence data were then analyzed using the MEGA11 and DnaSP 6 software. Our findings revealed 120 variable sites within the 691 base pairs of mtDNA COII sequences, resulting in a nucleotide diversity (Pi) of 0.07169. Furthermore, we identified eight haplotypes, demonstrating a haplotype diversity (Hd) of 0.8889. Remarkably, all mackerel samples from Palembang and Cilacap clustered into discrete haplotypes, specifically haplotype 1 and haplotype 2, respectively. Our phylogenetic analysis delineated three distinct clades. Clade I, closely related to Scomberomorus cavalla, encompassed all individuals from Ambon, Palembang, Rembang, and one from Banjarmasin. Clade II, associated with Scomberomorus niphonius, included individuals from Cilacap and two from Banjarmasin. Clade III, linked to Scomberomorus semifasciatus, exclusively consisted of individuals from Fak-Fak (Papua). In conclusion, Indonesian waters harbor diverse genetic variations within Scomberomorus spp., and population relationships based on the mtDNA COII gene exhibit notable complexities. Future research endeavors should focus on further elucidating the diversity and relationships among Scomberomorus spp. in diverse Indonesian populations.

Ecophenotypic Variation of Midas Cichlid, Amphilophus citrinellus (Gunther, 1864), in Lake Batur, Bali, Indonesia.

Cichlid fishes exhibit rapid adaptive radiations with significant diversification rates in response to ecological variability, i.e., ecological opportunity or geographical isolation. The discovery of a Midas cichlid species in Lake Batur, Indonesia's largest volcanic lake, first reported in 2013, could represent such adaptations. Midas cichlids can now be found in a range of habitats in Lake Batur and dominate the lake's fish population by up to 60%. This study aimed to identify the interaction between habitat, water quality, and Midas cichlid in Lake Batur, facilitating morphometric variances in the fish populations. The fish were captured at five locations in Lake Batur using fishing rods, community nets with mesh sizes of 2-3 inches, experimental gillnets with mesh sizes of 1 inch, and fish scoops in floating net cages during August and November 2022. There were 46 fish samples caught from the five stations, all photographed using a digital camera and later measured using the ZEN 2012 software. The fish measurement employed a truss morphometric method using 21 distinct morphometric body features. Canonical analysis was used to determine the distribution of characteristics, while discriminant analysis was used to examine the closeness of association. The measured water quality parameters included pH, DO, temperature, conductivity, and TDS for in-situ and TSS, TP, TN, and chlorophyll A for ex-situ. The findings revealed morphometric changes among Midas cichlid species in Lake Batur caused by habitat and water quality differences. The distinction can be detected in the anterior and posterior bodies (C1, B1, C3, C6, C5, B3 and B4). Temperature and aquatic plants, Azolla pinnata, may detect the station and shape of fish in Lake Batur. Body shape cannot be identified by chlorophyll A, TN, DO, and TDS. Future genetic research could answer why fish groups with varied body types coexist in the same location.

In vitro investigation on Pennisetum purpureum leaf extracts grown in Indonesia of phytochemical components, optical characteristics, and antioxidant-antibacterial activities.

Medicinal plants hold significant cultural significance and play a crucial role in the advancement of potentially safe drugs for the therapy of disease worldwide. Pennisetum purpureum or elephant grass has been used for traditional medications in Indonesia without understanding the phytochemicals of those plants. Herein, our report revolves around the qualitative and quantitative examination of phytochemical components, optical properties, antioxidants, and antibacterial assessments of solvent fractions derived from Pennisetum purpureum leaf. The Pennisetum purpureum leaf was successfully soaked with ethanol, n-hexane, and chloroform. The study aimed to assess the total phenolic content (TPC), total flavonoid content (TFC), and total alkaloid content (TAC) within different of extracts. The optical properties of extract were analyzed by absorption light and photoluminescent. Moreover, evaluation of antioxidant activities of extracts through DPPH free radical scavenging and FRAP assays, followed by an evaluation of their effectiveness in antibacterial therapy against different bacterial strains. The qualitative and quantitative phytochemical of Pennisetum purpureum presented as highest in ethanol TPC (85.5 mg GAE/g extracts), TFC (87.9 mg QE/g extracts), and TAC (86.2 mg ATE/g extracts) as compared to other solvents extract. Pennisetum purpureum extract had antioxidant capacity against DPPH radical and FRAP assay. Furthermore, each of the samples displayed antibacterial effectiveness that was dependent on the dosage towards different strains of bacteria. Our findings clearly demonstrated that Pennisetum purpureum leaf extracts grown in Indonesia containing alkaloid, flavonoid, glycoside, saponin, steroids, tannin, and terpenoids that support its capability as antioxidant and antibacterial.

Meiotic Spindle View improves the Outcome of IVF in Poor Responders: A Retrospective Analytical Study from an Indonesian IVF Center.

OBJECTIVE: Previous studies have shown that the meiotic spindle is not always aligned with the first polar body (PB) in metaphase II human oocytes. Polarized Light Microscopy (PLM) has been used to observe and locate the meiotic spindle to avoid disrupting it while injecting oocytes. The aim of this study is to evaluate the relationship between meiotic spindle view and IVF-ICSI outcomes in poor responder women. METHODS: This study was a retrospective analytical study, carried out from January to November 2019; involving 115 poor responder women who underwent IVF-ICSI cycles at the Halim Fertility Center, Indonesia. The patients were divided into two groups: group I without meiotic spindle viewing (non-MSV) as control group, and group II with meiotic spindle viewing (MSV) as the case group. The meiotic spindles were imaged before ICSI with Oosight microscopy. Baseline characteristics and IVF-ICSI outcomes of both groups were compared. RESULTS: Our study included 115 poor responder women with non-MSV group (71 women), and an MSV group (44 women). The results showed that there was no significant difference in the fertilization rate between the two groups (p>0.05), but the embryo cleavage rate was higher in the MSV group when compared to the non-MSV group; and there was a significant difference between the two groups (p<0.05). The fertilization rate was higher in aligned than misaligned spindle and there was a significant difference between the two groups (p<0.05). Good quality embryo was higher in MSV group than non-MSV group (59.05% vs. 63.95%). CONCLUSIONS: Meiotic spindle view might improve the outcome of IVF in poor responder women.

Biological Identification of Skulls in Indonesian and Thai Populations: Ancestry Estimation, Sex Determination, Stature Estimation, and Age Estimation / Identificación Biológica de Cráneos en Poblaciones de Indonesia y Tailandia: Estimación de Ascendencia, Determinación del Sexo, Estimación de Estatura y Estimación de Edad

SUMMARY: This review article will present an overview of biological profiles in forensic utilities. The biological profile of the skull in the existing literature can help to identify humans, especially if the condition of the victim found is a result of mutilation or a bomb explosion. When it comes to the precision of identifying skeletal remains, the human skull is frequently cited as being first in the estimation of age and ancestry and second in terms of sex and stature. It can be an alternative to assessing the following biological parameters: sex, age, stature, and ancestry. The implementation of biological profiles in the identification process is very important considering that some cases require the assistance of forensic anthropology. This review article shows the importance of the value of skulls. The method that can be applied is craniometry which can be used to determine sex, age, stature, and estimated ancestry. Different results will occur depending on the completeness of the skull. Therefore, estimation formulas have different accurate results. Discriminant function analysis has been performed on various measurement sets and its discriminant power has been validated by many researchers. Geometric morphometric analysis has become the main tool for shape analysis and many attempts have been made to use it in analyzing skulls. Several methods supported by technology have also been developed. It is hoped that the review article will show significant differences in results between studies in Thailand and Indonesia, even though they are in the same racial group.

Este artículo presenta una descripción general de los perfiles biológicos en las utilidades forenses. El perfil biológico del cráneo en la literatura existente puede ayudar a identificar a los humanos, especialmente si la condición en la que se encuentra la víctima es el resultado de una mutilación o la explosión de una bomba. Cuando se trata de la precisión en la identificación de restos óseos, el cráneo humano se cita con frecuencia como el primero en la estimación de edad y ascendencia y el segundo en términos de sexo y estatura. Puede ser una alternativa para evaluar los siguientes parámetros biológicos: sexo, edad, estatura y ascendencia. La implementación de perfiles biológicos en el proceso de identificación es importante considerando que algunos casos requieren la asistencia de la antropología forense. Este artículo de revisión muestra la importancia del valor de las cnezas óseas. El método que se puede aplicar es la craneometría para determinar el sexo, la edad, la estatura y la ascendencia estimada. Se pueden obtener diferentes resultados dependiendo de la integridad del cráneo. Por lo tanto, las fórmulas de estimación tienen resultados precisos diferentes. Se ha realizado un análisis de función discriminante en varios conjuntos de medidas y muchos investigadores han validado su poder discriminante. El análisis a través de la morfometría geométrica se ha convertido en la principal herramienta para el análisis de formas y se ha utilizado frecuentemente en el análisis de cráneos. También se han desarrollado varios métodos apoyados en la tecnología. Se espera que este trabajo muestre diferencias significativas en los resultados entre los estudios realizados en Tailandia e Indonesia, aunque pertenezcan al mismo grupo racial.
