Draft genome sequence of Hahella sp. CR1 and its ability in producing cellulases for saccharifying agricultural biomass.

Hahella is a genus that has not been well-studied, with only two identified species. The potential of this genus to produce cellulases is yet to be fully explored. The present study isolated Hahella sp. CR1 from mangrove soil in Tanjung Piai National Park, Malaysia, and performed whole genome sequencing (WGS) using NovaSeq 6000. The final assembled genome consists of 62 contigs, 7,106,771 bp, a GC ratio of 53.5%, and encoded for 6,397 genes. The CR1 strain exhibited the highest similarity with Hahella sp. HN01 compared to other available genomes, where the ANI, dDDH, AAI, and POCP were 97.04%, 75.2%, 97.95%, and 91.0%, respectively. In addition, the CAZymes analysis identified 88 GTs, 54 GHs, 11 CEs, 7 AAs, 2 PLs, and 48 CBMs in the genome of strain CR1. Among these proteins, 11 are related to cellulose degradation. The cellulases produced from strain CR1 were characterized and demonstrated optimal activity at 60 ℃, pH 7.0, and 15% (w/v) sodium chloride. The enzyme was activated by K+, Fe2+, Mg2+, Co2+, and Tween 40. Furthermore, cellulases from strain CR1 improved the saccharification efficiency of a commercial cellulase blend on the tested agricultural wastes, including empty fruit bunch, coconut husk, and sugarcane bagasse. This study provides new insights into the cellulases produced by strain CR1 and their potential to be used in lignocellulosic biomass pre-treatment.

Determinants of Bangladeshi patients' decision-making process and satisfaction toward medical tourism in India.

Objectives: The aims are to explore the factors influencing Bangladeshi patients' decision-making process and their satisfaction level toward medical tourism in India. Methods: The study used a quantitative research approach with a cross-sectional survey. Data were collected from the patients or their relatives (N = 388) who would have decided to travel to India for medical and treatment purposes at the Chittagong Indian visa center (IVAC). Data were collected using a structured, pre-tested, and facilitator-administered questionnaire, which mainly included the social demographic characteristics, health status, medical tourism information and medical tourism index. Hierarchical regression analysis was performed to explore the factors influencing their satisfaction level toward medical tourism in India. Results: More than three-fourths of the participants had visited India for self-treatment. Of the participants, 14% were cardiology patients, and 13% suffered from cancer. The relatives were the key source of information regarding medical tourism for more than one-fourth of the respondents. India's availability of well-experienced doctors, hospital/medical facilities with high standards, well-trained doctors, reputable doctors, and quality treatments and medical materials were top-ranked items. Regression results depict that facility and services appeared as the strongest factor (ß = 0.24, t = 4.71, p < 0.001) followed by tourism destination factor (ß = 0.16, t = 3.11, p = 0.002), medical tourism costs factor (ß = 0.16, t = 3.24, p = 0.001) and country environment factor (ß = 0.15, t = 2.69, p = 0.007). Conclusions: We found that the factor related to facility and services is one of the strongest predictors in our models. Therefore, home countries must strengthen the health care providers' advanced professional training, including service attitudes. Moreover, it is important to lessen the language barrier, reduce the airfare for medical tourists, and make the treatment cost more affordable for patients.

Draft genome sequence of Joostella atrarenae M1-2T with cellulolytic and hemicellulolytic ability.

The halophilic genus Joostella is one of the least-studied genera in the family of Flavobacteriaceae. So far, only two species were taxonomically identified with limited genomic analysis in the aspect of application has been reported. Joostella atrarenae M1-2T was previously isolated from a seashore sample and it is the second discovered species of the genus Joostella. In this project, the genome of J. atrarenae M1-2T was sequenced using NovaSeq 6000. The final assembled genome is comprised of 71 contigs, a total of 3,983,942 bp, a GC ratio of 33.2%, and encoded for 3,416 genes. The 16S rRNA gene sequence of J. atrarenae M1-2T shows 97.3% similarity against J. marina DSM 19592T. Genome-genome comparison between the two strains by ANI, dDDH, AAI, and POCP shows values of 80.8%, 23.3%, 83.4%, and 74.1% respectively. Pan-genome analysis shows that strain M1-2T and J. marina DSM 19592T shared a total of 248 core genes. Taken together, strain M-2T and J. marina DSM 19592T belong to the same genus but are two different species. CAZymes analysis revealed that strain M1-2T harbors 109 GHs, 40 GTs, 5 PLs, 9 CEs, and 6 AAs. Among these CAZymes, while 5 genes are related to cellulose degradation, 12 and 24 genes are found to encode for xylanolytic enzymes and other hemicellulases that involve majorly in the side chain removal of the lignocellulose structure, respectively. Furthermore, both the intracellular and extracellular crude extracts of strain M1-2T exhibited enzymatic activities against CMC, xylan, pNPG, and pNPX substrates, which corresponding to endoglucanase, xylanase, ß-glucosidase, and ß-xylosidase, respectively. Collectively, description of genome coupled with the enzyme assay results demonstrated that J. atrarenae M1-2T has a role in lignocellulosic biomass degradation, and the strain could be useful for lignocellulosic biorefining.

Fermented Soybean Meal (FSBM) in African Catfish (Clarias gariepinus) Diets: Effects on Growth Performance, Fish Gut Microbiota Analysis, Blood Haematology, and Liver Morphology.

The study revealed the potential of fermented soybean meal (FSBM) as a fish meal (FM) replacement in African catfish (Clarias gariepinus) feed formulation. Five isonitrogenous diets (32% crude protein) were prepared with five different levels of FSBM as FM replacement, namely 0% FSBM (T1), 40% FSBM (T2), 50% FSBM (T3), 60% FSBM (T4), and 70% (T5). The experimental fish was given the formulated diet for eight consecutive weeks. At the end of the feeding trial, the fish were subjected to growth performance, blood parameters, blood chemical, liver histology, and gut microbiota assessment. The study findings demonstrated that the experimental fish that received the T2 diet exhibited significantly higher (p < 0.05) growth performance. Experimental fish that received diet T2 had significantly higher (p < 0.05) white blood cell (WBC) and significantly lower (p < 0.05) in terms of cholesterol (CHOL), albumin (ALB), globulin (GLOB), and total protein (TP). The replacement of FSBM to FM significantly affected liver morphology on the sinusoid, vacuole, nucleus, and erythrocytes. Gut microbiota composition analysis showed a significantly high abundance (p < 0.05) of Akkermansia muciniphila in the experimental fish that received the T2 diet. The gut microbiota indicates that the experimental fish is in a healthy condition. In conclusion, replacing 40% FSBM with FM in aquafeed could enhance C. gariepinus growth performance and health conditions.

Tissue Rigidity Increased during Carcinogenesis of NTCU-Induced Lung Squamous Cell Carcinoma In Vivo.

Increased tissue rigidity is an emerging hallmark of cancer as it plays a critical role in promoting cancer growth. However, the field lacks a defined characterization of tissue rigidity in dual-stage carcinogenesis of lung squamous cell carcinoma (SCC) in vivo. Pre-malignant and malignant lung SCC was developed in BALB/c mice using N-nitroso-tris-chloroethylurea (NTCU). Picro sirius red staining and atomic force microscopy were performed to measure collagen content and collagen (diameter and rigidity), respectively. Then, the expression of tenascin C (TNC) protein was determined using immunohistochemistry staining. Briefly, all tissue rigidity parameters were found to be increased in the Cancer group as compared with the Vehicle group. Importantly, collagen content (33.63 ± 2.39%) and TNC expression (7.97 ± 2.04%) were found to be significantly higher (p < 0.05) in the Malignant Cancer group, as compared with the collagen content (18.08 ± 1.75%) and TNC expression (0.45 ± 0.53%) in the Pre-malignant Cancer group, indicating increased tissue rigidity during carcinogenesis of lung SCC. Overall, tissue rigidity of lung SCC was suggested to be increased during carcinogenesis as indicated by the overexpression of collagen and TNC protein, which may warrant further research as novel therapeutic targets to treat lung SCC effectively.

Rigid Tissue Increases Cytoplasmic pYAP Expression in Pre-Malignant Stage of Lung Squamous Cell Carcinoma (SCC) In Vivo.

Increased tissue rigidity is able to activate the Hippo signaling pathway, leading to YAP inactivation by phosphorylation and translocation into the cytoplasm. Accumulating evidence suggests that cytoplasmic pYAP serves as a tumor suppressor and could be a prognostic biomarker for several solid cancers. However, the relationship between tissue rigidity and cytoplasmic pYAP expression in the early stage of lung squamous cell carcinoma (SCC) remains elusive; this was determined in this study by using a mouse model. Female BALB/c mice were assigned into two groups (n = 6; the vehicle (VC) and the pre-malignant (PM) group, which received 70% acetone and 0.04 M N-nitroso-tris-chloroethylurea (NTCU) for 15 weeks, respectively. In this study, the formation of hyperplasia and metaplasia lesions was found in the PM group, indicating the pre-malignant stage of lung SCC. The pre-malignant tissue appeared to be more rigid as characterized by significantly higher (p < 0.05) epithelium thickness, proliferative activity, and collagen content than the VC group. The PM group also had a significantly higher (p < 0.05) cytoplasmic pYAP protein expression than the VC group. In conclusion, increased tissue rigidity may contribute to the upregulation of cytoplasmic pYAP expression, which may act as a tumor suppressor in the early stage of lung SCC.

Family planning knowledge, attitude and practice among Rohingya women living in refugee camps in Bangladesh: a cross-sectional study.

BACKGROUND: Considering the high risk of maternal morbidity and mortality, increased risks of unintended pregnancy, and the unmet need for contraceptives prevalent among the Rohingya refugees, this study aims to explore the knowledge, attitude, and practice (KAP) of family planning (FP) and associated factors among Rohingya women living in refugee camps in Bangladesh. METHODS: Four hundred Rohingya women were interviewed. Data were collected using a structured and pretested questionnaire, which included study participants' socio-demographic characteristics, access to FP services, knowledge, attitude, and practice of FP. Linear regression analysis was performed to identify the influencing factors of FP-KAP. RESULTS: Of the 400 Rohingya refugee women, 60% were unaware that there was no physical harm brought by using a permanent method of birth control. Half of the women lack proper knowledge regarding whether a girl was eligible for marriage before the age of 18. More than two-thirds of the women thought family planning methods should not be used without the husband's permission. Moreover, 40% were ashamed and afraid to discuss family planning matters with their husbands. Of the study participants, 58% had the opinion that a couple should continue bearing children until a son is born. Linear regression analyses found that study participants' who have a profession, have less children, whose primary source of FP knowledge was through a physician/nurse, have had FP interventions in the camp, and talk with a health care provider on FP were found to have better FP-KAP. CONCLUSION: The study showed that Rohingya refugee women are a marginalized population in terms of family planning and their comprehensive FP-KAP capability was low. Contraceptives among the Rohingyas were unpopular, mainly due to a lack of educational qualifications and family planning awareness. In addition, family planning initiatives among Rohingya refugees were limited by a conservative culture and religious beliefs. Therefore, strengthening FP interventions and increasing the accessibility to essential health services and education are indispensable to improving improve maternal health among Rohingya refugees.

Considering the high risk of maternal morbidity and mortality, increased risks of unintended pregnancy, and the unmet need for contraceptives prevalent among the Rohingya refugees, this study aims to explore the knowledge, attitude and practice (KAP) of family planning (FP) and associated factors among Rohingya women living in the refugee camps in Cox's Bazar, Bangladesh. Four hundred Rohingya women participated in the study. We found that Rohingya refugee women were a marginalized population in family planning and their comprehensive FP-KAP status was low. Contraceptive uptake among the Rohingya women was low due to a lack of education and family planning awareness. In addition, family planning initiatives among Rohingya refugees were limited by various traditional cultural and religious beliefs. Therefore, strengthening FP interventions and increasing accessibility to essential health services and education are indispensable to improving maternal health among refugees.

Linking electricity demand and economic growth in China: evidence from wavelet analysis.

The study empirically examines the association between electricity demand and economic growth in China in a time-frequency framework. Wavelet coherence analysis and phase difference methods are applied to find the co-movement and causality between variables using monthly data for 1999 to 2017 time period. The results of the wavelet power spectrum show that both series have high fluctuations at high frequencies. The findings of wavelet coherence reveal co-movements between electricity demand and economic growth at different frequency levels. However, this association is stronger at low-frequency levels. Evidence from the phase difference indicates that electricity is causing economic growth with a positive sign. The results of wavelet-based correlation also show a high correlation between these two variables. For robustness analysis, linear and nonlinear causality tests are applied to find causality between variables over time. Both linear and nonlinear causality tests reveal bidirectional causality between variables. It corroborates the result of wavelet causality that both variables cause each other at different frequency levels.

Evaluating the effectiveness of utilization of health communication interventions on sexual and reproductive health of the Rohingya women living in Cox's Bazar refugee camp.

Objectives: This study aimed to examine the effectiveness of NGOs' health communication interventions (HCIs) regarding sexual and reproductive health (SRH) among the Rohingya women living in the refugee camps in Cox's Bazar, Bangladesh. Methods: A camp-based cross-sectional questionnaire survey was conducted from November 10, 2019, to January 10, 2020, among 415 Rohingya married women of reproductive age (above 18-49 years) living in the refugee camp in Cox's Bazar, Bangladesh. The study participants were selected using a convenient sampling. The independent-sample t-test and hierarchical regression analysis were performed using IBM SPSS version 24.0. Results: Different myths and perceptions of taboo are common among the Rohingya women regarding SRH which imposes some restrictions on them. Of the Rohingya women, 79.8 percent ever had a consultation with non-government organizations' (NGOs) appointed health care providers (doctors/nurses) regarding SRH issues, while only 68.4 percent of them had a door visit by the NGO workers in this regard. Moreover, 62.7 percent participated in NGO's SRH communication program, whereas three-fourths understood the SRH messages appropriately. However, the study findings reported significant differences (p ≤ .001) in the mean scores of all items related to participants' SRH status for the difference in the utilization level of health communication interventions. Regression analysis shows that the Rohingya women's utilization of NGOs' health communication interventions appeared as stronger predictors than socioeconomic variables for better SRH status. At the same time, ß values indicate that the Rohingya women's interpersonal communication with a health care provider and understanding the messages of communication activities are reported as the strongest predictors of outcome variables. Conclusion: Health communication interventions significantly influence positive changes in women's SRH. Accordingly, this study recommends strengthening communication interventions using behavioral change theories and strategic communication approaches as it is difficult to change their socioeconomic status in existing settings.

NTCU induced pre-malignant and malignant stages of lung squamous cell carcinoma in mice model.

Mice have served as an excellent model to understand the etiology of lung cancer for years. However, data regarding dual-stage carcinogenesis of lung squamous cell carcinoma (SCC) remain elusive. Therefore, we aim to develop pre-malignant (PM) and malignant (M) lung SCC in vivo using N-nitroso-tris-chloroethylurea (NTCU). BALB/C mice were allotted into two main groups; PM and M groups which received treatment for 15 and 30 weeks, respectively. Then, the mice in each main group were allotted into three groups; control, vehicle, and cancer (n = 6), which received normal saline, 70% acetone, and 0.04 M NTCU by skin painting, respectively. Histopathologically, we discovered a mix of hyperplasia, metaplasia, and dysplasia lesions in the PM group and intracellular bridge; an SCC feature in the M group. The M group was positive for cytokeratin 5/6 protein which confirmed the lung SCC subtype. We also found significantly higher (P < 0.05) epithelium thickness in the cancer groups as compared to the vehicle and control groups at both the PM and M. Overall, this study discovered that NTCU is capable of developing PM and M lung SCC in mice model at appropriate weeks and the vehicle group was suggested to be adequate as control group for future research.

Appointment Length with Patients in Medical Consultations in Bangladesh: A Hospital-Based Cross-Sectional Study.

In medical consultations, the length of the visit has a significant impact on the quality of care. It is significantly associated with a better quality of treatment and better health outcomes. In this study, we analyzed doctors' consultation length with patients and associated factors in Bangladesh. A cross-sectional survey was conducted among the patients (N = 763) who visited the doctors in six district/upazila (sub-district) hospitals in the Chittagong Hill Tracts (CHT) area. Linear regression analyses were performed to identify the determining factors associated with the length of doctors' appointments with patients. Data were analyzed using IBM SPSS version 24.0. Among the patients, 319 (41.8%) were female and 688 (90.2%) lived in rural/suburban areas. This study revealed that the average length of medical consultations was 9.10 min. Additionally, our findings illustrated that doctors' patient-centered communication behavior (ß = 0.23, p < 0.001) appeared to be the strongest predictor of longer visit length. It was also found that patients' higher education level (ß = 0.10, p = 0.006), having adequate knowledge about the health problem (ß = 0.13, p < 0.001), follow-up visits (ß = 0.13, p < 0.001), and the presence of female doctors (ß = 0.19, p < 0.001) were significantly associated with longer interview times between doctors and patients in primary care settings. Given that doctors' patient-centered communication behavior appears to play the most important role, this study suggests that practicing professionalism in medical consultations, developing effective communication skills and increasing awareness of sociodemographic discrepancies are important to ensure longer appointment lengths and better health outcomes of patients, regardless their sociodemographic and socioeconomic status.

The classification of skateboarding tricks via transfer learning pipelines.

This study aims at classifying flat ground tricks, namely Ollie, Kickflip, Shove-it, Nollie and Frontside 180, through the identification of significant input image transformation on different transfer learning models with optimized Support Vector Machine (SVM) classifier. A total of six amateur skateboarders (20 ± 7 years of age with at least 5.0 years of experience) executed five tricks for each type of trick repeatedly on a customized ORY skateboard (IMU sensor fused) on a cemented ground. From the IMU data, a total of six raw signals extracted. A total of two input image type, namely raw data (RAW) and Continous Wavelet Transform (CWT), as well as six transfer learning models from three different families along with grid-searched optimized SVM, were investigated towards its efficacy in classifying the skateboarding tricks. It was shown from the study that RAW and CWT input images on MobileNet, MobileNetV2 and ResNet101 transfer learning models demonstrated the best test accuracy at 100% on the test dataset. Nonetheless, by evaluating the computational time amongst the best models, it was established that the CWT-MobileNet-Optimized SVM pipeline was found to be the best. It could be concluded that the proposed method is able to facilitate the judges as well as coaches in identifying skateboarding tricks execution.

PTEN protein expression has role in predicting disease-free-interval in endometrioid endometrial carcinoma.

OBJECTIVES: To determine the significance of tumour PTEN protein expression in endometrioid endometrial carcinoma (EEC) and it is correlation with tumour characteristics. METHODS: A total of 30 eligible archived paraffin-embedded tissue blocks from 61 EEC cases (January 2015-December 2017) were retrieved from the Histopathology Laboratory in Universiti Kebangsaan Malaysia Medical Centre (UKMMC) following institutional ethic approval. For PTEN protein detection, immunohistochemistry (IHC) staining was performed and the data was correlated with clinicopathologic parameters. RESULTS: Fourteen samples (46.7%) showed positive PTEN protein expression, while 16 (53.3%) were negative. The mean age was 62.00 ± 9.51 years old, while the mean Body Mass Index (BMI) was 27.28 ± 7.16 kg/m2. There was no significant difference between age (p=0.27, 95% CI: -10.98 to 3.21) and BMI (p=0.67, 95% CI: -4.30 to 6.58) with PTEN protein expression. There were significant correlation between PTEN protein expression with myometrial invasion (p=0.010), but not with lymphovascular space invasion (p=0.743), grade (p=0.532), stage (p=0.733) and CA-125 level (p=0.47). The higher stage correlates with the presence of LVSI (p=0.002). PTEN positive associated with longer disease-free-interval (p=0.025), but not improving the overall survival (p=0.38). CONCLUSIONS: Positive PTEN protein expression correlates with less myometrial invasion.

Women's Perception of Male Involvement in Antenatal, Childbirth and Postnatal Care in Urban Slum Areas in Bangladesh: A Community-Based Cross-Sectional Study.

Male participation in reproductive health issues has been considered to be an effective and promising strategy to address the women's reproductive health problems since the 1990s. Under this background, we aim to explore the women's perception of men's involvement in antenatal care (ANC), delivery and postnatal care (PNC) in the slum community of Bangladesh where various sexual and reproductive health problems exist. A community-based cross-sectional study was conducted among women and their husbands living in 12 slums of Chattogram city. Cross-tabulation with chi-square tests and multivariate logistic regression analyses were performed to examine the predictors of husbands' support in wives' antenatal, delivery and postnatal care. The study demonstrates that the education and economic level of most women and their husbands were very low although husbands seemed to have a better status than wives in these aspects. Almost all men (~90%) had never accessed services related to reproductive and maternal health. Only 10% of respondents gave birth to their last baby in government hospitals or private clinics. In addition, 60% of the husbands took care of their wives during pregnancy with 44% during childbirth and about 30% providing help in receiving postpartum care. Moreover, husbands' discussions with a health worker regarding maternal and reproductive health were the most important predictors for support of their wives during pregnancy, childbirth and postpartum care (p < 0.05). Study participants' perception of a satisfying spousal relationship also appeared to be a significant factor for husbands' responsible role regarding wives' antenatal care, delivery and postnatal care (p < 0.05). This study found that pregnant women living in slums received poorer health-related services when there was a low involvement of men; specifically, the husbands of pregnant women. In addition, men's involvement was influenced by many aspects, particularly awareness-related factors (e.g., knowledge, communication and access to reproductive health services). Therefore, awareness creation is important for active involvement in antenatal, delivery and postnatal care. Strategies should be designed to provide men living in the slums with adequate information, education and communication to gain their interest and support about reproductive and maternal health.

Complexity and Specificity of Sec61-Channelopathies: Human Diseases Affecting Gating of the Sec61 Complex.

The rough endoplasmic reticulum (ER) of nucleated human cells has crucial functions in protein biogenesis, calcium (Ca2+) homeostasis, and signal transduction. Among the roughly one hundred components, which are involved in protein import and protein folding or assembly, two components stand out: The Sec61 complex and BiP. The Sec61 complex in the ER membrane represents the major entry point for precursor polypeptides into the membrane or lumen of the ER and provides a conduit for Ca2+ ions from the ER lumen to the cytosol. The second component, the Hsp70-type molecular chaperone immunoglobulin heavy chain binding protein, short BiP, plays central roles in protein folding and assembly (hence its name), protein import, cellular Ca2+ homeostasis, and various intracellular signal transduction pathways. For the purpose of this review, we focus on these two components, their relevant allosteric effectors and on the question of how their respective functional cycles are linked in order to reconcile the apparently contradictory features of the ER membrane, selective permeability for precursor polypeptides, and impermeability for Ca2+. The key issues are that the Sec61 complex exists in two conformations: An open and a closed state that are in a dynamic equilibrium with each other, and that BiP contributes to its gating in both directions in cooperation with different co-chaperones. While the open Sec61 complex forms an aqueous polypeptide-conducting- and transiently Ca2+-permeable channel, the closed complex is impermeable even to Ca2+. Therefore, we discuss the human hereditary and tumor diseases that are linked to Sec61 channel gating, termed Sec61-channelopathies, as disturbances of selective polypeptide-impermeability and/or aberrant Ca2+-permeability.

Disparity in physician-patient communication by ethnicity: evidence from Bangladesh.

BACKGROUND: Physician-patient communication behavior (PPCB) is the primary process by which medical decision-making occurs and health outcome depends. Physician-patient communication differences may partly from the ethnic disparities. To examine this problem, this study aims to explore whether physician-patient communication differs by ethnicity during primary care medical consultations. METHODS: The study was conducted among the Bengali and ethnic minority patients (N = 850) who visited a physician for medical consultations. Data were collected using a structured post-consultation questionnaire. T-test was conducted to compare the communication between the Bengali and ethnic minority patients. Multiple linear regression analyses were performed to identify the factors associated with favorable communication behavior from the physicians. RESULTS: Bengali patients received more supportive communication behaviors from the Bengali doctors than that of ethnic minority patients including physicians' cheerful greetings, encouraging patients to express health problems and asking questions, listening carefully, responding to questions and concerns, explaining to patients about medical examination procedures, medication, probable side effects, discussing treatment options, involved the patients in decisions, and spending adequate time. Results of linear regression showed that respondents' level of education, internet use, knowledge about the health issue, having a pre-organized plan about the content of medical consultation, information seeking about the health problem, visiting female doctors, and a quiet ambience of the doctor's room are significantly associated with a better PPCB score for the Bengali patients. In contrast, age, being the resident of an urban area, perception of affecting a minor health problem, having a pre-organized plan about the content of medical consultation, patients' involvement in physicians' decision-making about the treatment, and talking time resulted in better physician-patient communication for the ethnic minority patients. CONCLUSION: This study suggests that reducing disparity in the socio-economic status of the ethnic minority groups through development programs and educating healthcare providers on how to use patient-centered communication skills to engage with their patients is one solution to improve equity in the delivery of healthcare and ensure than patients are receiving high-quality treatment, no matter their race or ethnicity.

Roles of Rho­associated kinase in lung cancer (Review).

Lung cancer is one of the most lethal forms of cancer known to man, affecting millions of individuals worldwide. Despite advancements being made in lung cancer treatments, the prognosis of patients with the disease remains poor, particularly among patients with late­stage lung cancer. The elucidation of the signaling pathways involved in lung cancer is a critical approach for the treatment of the disease. Over the past decades, accumulating evidence has revealed that Rho­associated kinase (ROCK) is overexpressed in lung cancer and is associated with tumor growth. The present review discusses recent findings of ROCK signaling in the pathogenesis of lung cancer that were conducted in pre­clinical studies. The significant role of ROCK in cancer cell apoptosis, proliferation, migration, invasion and angiogenesis is discussed. The present review also suggests the use of ROCK as a potential target for the development of lung cancer therapies, as ROCK inhibition can reduce multiple hallmarks of cancer, particularly by decreasing cancer cell migration, which is an initial step of metastasis.

The first section shows an overview on the biodiesel as an alternative fuel in transportation. The next section will focus on a comparative study between Malaysia and Colombia biodiesel sector in terms of energy supply, resource, production and consumption, standards, techno-economic cost and their biodiesel policies. A comprehensive review was studied to discuss on the sustainability of palm cultivation and biodiesel, impact of palm industry and biodiesel policy in transportation sector and potential international collaboration between Malaysia and Colombia to improve their existing policies, strategies and blueprints related to the palm biodiesel industry, thus overcoming the challenges when dealing with global energy issue.

Knowledge on, Attitude towards, and Practice of Sexual and Reproductive Health among Older Adolescent Girls in Bangladesh: An Institution-Based Cross-Sectional Study.

Improving the sexual and reproductive health (SRH) of adolescent girls is one of the primary aims of the Sustainable Development Goals (SDGs). Adequate and accurate knowledge, a favorable attitude, safe behavior, and regular practice contribute to adolescent girls' SRH, maternal health, and child health. Considering this, this study aims to explore the level of knowledge, attitudes, and practices (KAP) of SRH among college-going older adolescent girls in Chittagong district, Bangladesh. An institution-based cross-sectional study was conducted in four colleges among the older adolescent girl age group of 16-17 years old (N = 792) attending a higher secondary grade in Chittagong district. Data were collected using a structured and self-administered questionnaire. Descriptive statistics and multiple linear regression analyses were used to summarize the SRH-related KAP and identify the associated factors, respectively. The level of knowledge about puberty, family planning, maternal health, and HIV/AIDS was not satisfactory among the older adolescent girls. Different myths are common in the rural area with regards to menstruation, which impose several restrictions on adolescent girls and adult women. Standardized coefficients of beta (ß) and p value < 0.05 in linear regression analyses demonstrated that being a student of the science group (ß = 0.29, p < 0.001) and reading about or watching SRH issues on media (ß = 0.21, p < 0.001) were significantly associated with older adolescent girls' high level of knowledge in this regard. Furthermore, being a student of the science group (ß = 0.17, p < 0.001), urban residence (ß = 0.20, p < 0.001), regular SRH communication (at least once a month) with a mother/sister/friend (ß = 0.10, p = 0.003), and reading or watching any SRH content on media (ß = 0.22, p < 0.001) appeared as predictors of adolescent girls' positive attitude towards SRH issues. Moreover, being a student of the science group (ß = 0.07, p = 0.048), urban residence (ß = 0.22, p < 0.001), regular SRH discussions with a mother/sister/friend (ß = 0.09, p = 0.005), pre-knowledge on periods before menarche (ß = 0.12, p < 0.001), and reading or watching any SRH content on media (ß = 0.18, p < 0.001) are the most important factors influencing a regular hygienic practice of SRH. This study suggests strengthening SRH-related comprehensive education programs incorporated into the curriculum, the effective use of mass media, and supplying behavioral change communication materials.

Effect of Bulky Functional Groups on Donor and Acceptor Interactions and their Photoluminescence Properties.

Material designs that use donor and acceptor units are often found in organic optoelectronic devices. Molecular level insight into the interactions between donors and acceptors are crucial for understanding how such interactions can modify the optical properties of the organic optoelectronic materials. In this paper, tris(4-(tert-butyl)phenyl)amine (pTPA) was synthesized as a donor in order to compare with unmodified triphenylamine (TPA) in a donor-acceptor system by having 2,4,6-triphenyl-1,3,5-triazine (TRZ) as an acceptor. Dimerization of donors and acceptors occurred in solvent when the concentration of solute is high. At 0 K, using a polarizable continuum model, the nitrogen atom of TPA is found to stack on top of the center of triazine of TRZ, whereas such alignment is offset in pTPA and TRZ. We attributed such alignment in TPA-TRZ as the result of attractive interactions between partial localization of 2pz electrons at the nitrogen atom of TPA and the π deficiency of triazine in TPA-TRZ. By taking into account random motions of the solvent effect at 300 K in quantum molecular dynamics and classical molecular dynamics simulations to interpret the marked difference in emission spectra between TPA-TRZ and pTPA-TRZ, it was revealed that the attractive interaction between pTPA and TRZ in toluene is weaker than TPA and TRZ. Because of the weaker attractive interaction between pTPA and TRZ in toluene, the dimers adopted numerous ground state conformations resulting in broad emission bands superimposed with multiple small Gaussian peaks. This is in contrast to TPA-TRZ which has only one dominant dimer conformation. This study demonstrates that the strength of intermolecular interactions between donors and acceptors should be taken into consideration in designing supramolecular structures.
