RESUMO
A seven month, pot study was conducted to evaluate the impact of moderately saline wastewater on the growth potential of six forestry plant species viz., Eucalyptus calmaldulensis, Dendrocalamus strictus, Casurina equisetfolia, Cassia fistula, Melia dubia, and Bambusa arundinacea under different drainage conditions namely, well-drained saline (WDS) condition and poor-drained saline condition (PDS) and the control with well-drained non-saline condition. WDS treatment resulted in no mortality whereas PDS treatment resulted in mortality in the range of 33-66%. The plant height and root dry biomass increased in the range of 145% to 221.6% and 4.3-37.1 g respectively in WDS treatment, however, 23.60% to 173.4% and 4.1-10.1 g in PDS treatment. Among all, Eucalyptus camaldulensis and Dendrocalamus strictus showed high Na+ accumulation in roots (2.16 ± 0.02% and 1.13 ± 0.01%), shoots (1.98 ± 0.01% and 0.74 ± 0.01%) and leaves (1.27 ± 0.02% and 0.86 ± 0.01%) in WDS treatment and in case of PDS treatment root (1.01 ± 0.01% and 0.23 ± 0.01%), shoot (1.12 ± 0.02% and 0.11 ± 0.01%), and leaf (0.07 ± 0.01% and 0.1 ± 0.02). The overall performance of both Eucalyptus camaldulensis and Dendrocalamus strictus was highest in WDS treatment. Therefore, it was concluded, that both plants had better performance than other plant species, a proper drainage system defines the overall productivity and treatment efficiency.
Forestry is not only a necessity for increasing tree cover and decreasing pressure on natural forests but also a most desired land use plan especially for reclaiming and rehabilitating the degraded lands. This study concluded that salt-affected and waterlogged areas and moderately saline waters can be utilized satisfactorily in raising forests using suitable plant species. Eucalyptus camaldulensis and Dendrocalamus strictus which showed good performance for salt tolerance and survival can be effectively used to mitigate the problems of waterlogged conditions and soil salinity remediation. Utilizing these species extensively can be a sustainable and suitable approach to promote afforestation and mitigate the problems of waterlogged conditions and for green belt development.

FOXO1 transcription factor not only limits the cell cycle progression but also promotes cell death as a tumor suppressor protein. Though the expression of FOXO1 is largely examined in breast cancer, the regulation of FOXO1 by miRNA is yet to be explored. In the current study, self-assembled branched DNA (bDNA) nanostructures containing oncogenic miRNAs were designed and transfected to the MCF7 cell line to decipher the FOXO1 expression. bDNA containing oncogenic miRNAs 27a, 96, and 182 synergistically downregulate the expression of FOXO1 in MCF7 cells. The down-regulation is evident both in mRNA and protein levels suggesting that bDNA having miRNA sequences can selectively bind to mRNA and inhibit translation. Secondly, the downstream gene expression of p21 and p27 was also significantly downregulated in presence of miR-bDNA nanostructures. The cell proliferation activity was progressively increased in presence of miR-bDNA nanostructures which confirms the reduced tumor suppression activity of FOXO1 and the downstream gene expression. This finding can be explored to design novel bDNA structures which can downregulate the tumor suppressor proteins in normal cells and induce cell proliferation activity to identify early-phase markers of cancer.

Fishes have been widely used as a representative to estimate the health of an aquatic ecosystem. In the present study, Labeo rohita was selected for biomarker study against decabromodiphenyl ether (BDE-209), a persistent organic pollutant (POP), as it is a widely used Indian carp. The results suggested significant effects on the optimum metabolism of Labeo rohita. After 48 to 72 h of exposure, most of the biomarkers such as lactate dehydrogenase (LDH), creatine kinase (CK), serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), and hepatosomatic index (HSI) increased drastically indicating the higher index of tissue and liver damage. On the contrary, succinic dehydrogenase (SDH), acetylcholinesterase (AChE), and alkaline phosphatase (ALP) showed a reverse trend suggesting the shifting of fish metabolism towards anaerobic respiration mode because of induced stress. Increased catalase (CAT) activity was also observed, which indicated increased abundance of reactive hydroxyl species and therefore a possible oxidative stress in fishes. It is further suggested to understand and examine the biotransformation characteristics and degradation pathways of polybrominated diphenyl ether (PBDE)s, which would be useful to comprehend their environmental fate.

Climate change could impact nutrient bioavailability in aquatic environment. To understand the interaction of nutrient bioavailability and elevated CO2, Chlorella vulgaris cells were grown in ambient air or 5% CO2 in different concentrations of nitrogen and phosphorus in a photobioreactor. The chlorophyll content, photosynthesis and respiration rates increased in 5% CO2 to support higher biomass production. The nutrient limitation in the growth media resulted in reduced photosynthetic rates of the algal cells and their PSI, PSII, and whole chain electron transport rates and biomass production. Conversely, their lipid content increased partly due to upregulation of expression of several lipid biosynthesis genes. The order of downregulation of photosynthesis and upregulation in lipid production due to nutrient limitation was in the order of N > P. The N-50 and 5% CO2 culture had only 10% reduction in biomass and 32% increase in lipids having 85% saturated fat required for efficient biofuel production. This growth condition is ideal for generation of biodiesel required to reduce the consumption of fossil fuel and combat global warming.

BACKGROUND: Current therapy for Type 1 diabetes (T1D) is characterized by significant glucose variability (GV). Pancreas transplantation (PT) is performed in certain T1D patients with and without end-stage renal disease. To date, GV has been examined to a limited extent after PT. METHODS: We investigated GV using continuous glucose monitoring (CGM) 3-6 weeks after PT. RESULTS: Eleven patients had simultaneous kidney pancreas transplantation (SPK), nine pancreas after kidney (PAK), and six pancreas transplantation alone (PTA). Mean CGM showed no difference between SPK, 126.5 ± 13.9, PAK 119.9 ± 12.8, and PTA 131.1 ± 29 mg/dL (P value .6). Percentage of time in range (TIR, 70-180 mg/dL) was 92% for SPK, 93.4% in PAK, and 88.5% in PTA with only 0.3%, 1.5%, and 0.3% of time <70 mg/dL. Percentage >180 mg/dL was 7.9% for SPK, 4.9% PAK, and 11% in PTA. Other measures of GV were similar in the three cohorts. In six patients, CGM was performed before and after PT and improved significantly. GV was also better compared with a matched cohort of T1D patients. CONCLUSIONS: All 3 types of PT resulted in excellent glucose control 3-6 weeks post-procedure. CGM outcomes represent an important objective outcome after PT.

Synergy occurs when chemicals give pronounced effect on combination in contrast to their individual effect. The objective of this study was to investigate the synergistic effect of pesticides carbaryl (C) and methyl parathion (MP) on oxidative stress biomarkers viz catalase (CAT), glutathione reductase (GSSG-R) including different enzymes like lactate dehydrogenase (LDH), succinate dehydrogenase (SDH) and acetyl cholinesterase (AChE) in different tissues of carps Catla catla. Fishes were exposed to 6.25 mg/L of MP and 2.3 mg/L of C in mixture (one-third of LC50 value). CAT and GSSG-R were studied in gills, brain, liver and muscle of carp were found to be elevated significantly (p < 0.005). LDH activity increased significantly (p < 0.005) in synergistic group, there was a seven-fold (748%) increase in LDH activity in muscle compared to individual studies with same pesticides. Contrary to LDH, sudden decrease in SDH activity was accounted. Significant (p < 0.005) decrease in AChE activity after initial 24 h was remarkable addressing to the shift in neurotransmission pathway in organism. Significant increase was observed in activity of CAT and GSSG-R in all tissues compared to control fishes in individual as well as synergistic (MP + C) group suggesting that CAT and GSSG-R can be a potential biomarker of oxidative stress when studied in combination.

BACKGROUND: Orphan nuclear receptors ERRα, ERRß and ERRγ that belong to NR3B or type IV nuclear receptor family are well studied for their role in breast cancer pathophysiology. Their homology with the canonical estrogen receptor dictates their possible contributing role in mammary gland development and disease. Although function and regulation of ERRα, ERRγ and less about ERRß is reported, role of histone methylation in their altered expression in cancer cells is not studied. Transcriptional activity of nuclear receptors depends on co-regulatory proteins. The present study for the first time gives an insight into regulation of estrogen-related receptors by histone methylation specifically through methyltransferase EZH2 in breast cancer. METHODS: Expression of ERRα, ERRß, ERRγ and EZH2 was assessed by immunohistochemistry in four identical tissue array slides that were prepared as per the protocol. The array slides were stained with ERRα, ERRß, ERRγ and EZH2 simultaneously. Array data was correlated with expression in MERAV expression dataset. Pearson correlation coeficient r was calculated from the partial matrix expression values available at MERAV database to study the strength of association between EZH2 and three orphan nuclear receptors under study. By western blot and real time PCR, their correlated expression was studied in breast cancer cell lines MCF-7, MDA-MB-231, T47D and MDA-MB-453 including normal breast epithelial MCF-10A cells at both protein and RNA level. Regulation of ERRα, ERRß, ERRγ by EZH2 was further investigated upon overexpression and silencing of EZH2. The interaction between ERRs and EZH2 was validated in vivo by CHIP-qPCR. RESULTS: We found a negative correlation between estrogen-related receptors and Enhancer of Zeste Homolog 2, a global repressor gene. Immunohistochemistry in primary breast tumors of different grades showed a correlated expression of estrogen-related receptors and EZH2. Their correlated expression was further validated using online MERAV expression dataset where a negative correlation of variable strengths was observed in breast cancer. Ectopic expression of EZH2 in low EZH2-expressing normal breast epithelial cells abrogated their expression and at the same time, its silencing enhanced the expression of estrogen-related receptors in cancerous cells. Global occupancy of EZH2 on ERRα and ERRß was observed in-vivo. CONCLUSION: Our findings identify EZH2 as a relevant coregulator for estrogen-related receptors in breast carcinoma.

BACKGROUND: Well-known anti-malarial drug artemisinin exhibits potent anti-cancerous activities. In-vivo and in-vitro studies showed its anti-tumor and immunomodulatory properties signifying it as a potent drug candidate for study. The studies of mechanisms of cell movement are relevant which can be understood by knowing the involvement of genes in an effect of a drug. Although cytotoxicity and anti-proliferative activity of artemisinin is evident, the genes participating in its anti-migratory and reduced invasive effect are not well studied. The present study reports the alteration in the expression of 84 genes involved in cell motility upon artemisinin treatment in MCF-7 breast cancer cells using pathway focused gene expression PCR array. In addition, the effect of artemisinin on epigenetic modifier HDACs is studied. METHODS: We checked the functional stimulus of artemisinin on cell viability, migration, invasion and apoptosis in breast cancerous cell lines. Using qRT-PCR and western blot, we validated the altered expression of relevant genes associated with proliferation, migration, invasion, apoptosis and mammary gland development. RESULTS: Artemisinin inhibited cell proliferation of estrogen receptor negative breast cancer cells with fewer efficacies in comparison to estrogen receptor positive ones. At the same time, cell viability and proliferation of normal breast epithelial MCF10A cells was un-affected. Artemisinin strongly inhibited cancer cell migration and invasion. Along with orphan nuclear receptors (ERRα, ERRß and ERRγ), artemisinin altered the ERα/ERß/PR/Her expression status of MCF-7 cells. The expression of genes involved in the signaling pathways associated with proliferation, migration, invasion and apoptosis was significantly altered which cooperatively resulted into reduced growth promoting activities of breast cancer cells. Interestingly, artemisinin exhibited inhibitory effect on histone deacetylases (HDACs). CONCLUSIONS: Upregulated expression of tumor suppressor genes along with reduced expression of oncogenes significantly associated with growth stimulating signaling pathways in response to artemisinin treatment suggests its efficacy as an effective drug in breast cancer treatment.

Polybrominated diphenyl ethers (PBDEs) used extensively over the past 3 decades as flame retardants in most types of polymers, all over the world, have been identified as global pollutants. PBDEs pose various health problems such as thyroid hormone disruption, permanent learning and memory impairment, behavioral changes, hearing deficits, delayed puberty onset, fetal malformations, and possibly cancer. Many measurements of PBDEs in various matrices from Sweden, Holland, Japan, the USA, and elsewhere have been reported, but few measurements are available for India. In this study, a preliminary screening of different congeners of PBDEs has been performed in different old electronic and consumer products with an objective to build capacity in order to analyze PBDEs and BFRs. Six different samples, foam from upholstery, motherboard of a computer, children toy composite sample, old vanishing window blind sample, electrical wire sample, and PVC flooring sample, were collected and analyzed for the presence of the following PBDE congeners: BDE-28, BDE-47, BDE-99, BDE-100, BDE-153, BDE-154, BDE-183, and BDE-209. It was found that three out of six samples were positive for the presence of PBDEs. Three congeners were detected in the samples, i.e., BDE-47, BDE-153, and BDE-209, of which, highest concentration was of BDE-209. Among the samples, motherboard of computer showed the highest concentration of BDE-209 followed by window blind and foam from upholstery. The results of this preliminary investigation indicate that PBDEs are still present in the old consumer products which can be an important additional source of exposure to the population.

INTRODUCTION: Pregnant women with abnormal liver function tests (LFTs) require proper evaluation and timely management to reduce maternal and fetal morbidity and mortality. OBJECTIVE: The present study was done with the objective of determining feto-maternal outcomes in antenatal women with abnormal LFTs and comparing them with antenatal women having normal liver function. The prevalence and possible causes of derangements in LFT were also identified. METHOD: Pregnant women referred to an antenatal clinic for several reasons pertaining to abnormal liver functions, and those admitted to the labor room for delivery with abnormal LFTs were included in the study. The pregnant women with abnormal LFT were studied prospectively, and they were compared with pregnant women having normal LFT. The fetal and maternal outcomes were also noted. RESULTS: The pregnant women attending the antenatal clinic with a history of pruritus, abdominal pain, jaundice, nausea/vomiting, hypertension ascites, etc. and delivered at our facility were evaluated. One hundred and eight women had abnormal LFT defined by criteria laid down in material and methods. Eighty-seven women with normal LFT were taken for comparison. In the abnormal LFT, the main cause was intrahepatic cholestasis of pregnancy (IHCP). There were 6 (5.5%) maternal deaths in this group and none in the normal LFTs. There were 6 (5.6%) fetal deaths and 4 (4.6%) in the other group (p-value=1). The prevalence of abnormal LFT was 9.11% throughout pregnancy. Increased bilirubin and alkaline phosphatase (ALP) were significantly correlated with maternal mortality, while gestational age at birth, presence of meconium, appearance, pulse, grimace, activity, and respiration (APGAR) score, maternal mortality, and raised alkaline phosphatase level were found to be significantly associated with fetal mortality. CONCLUSION: Patients with abnormal LFT were significantly associated with maternal morbidity and mortality. However, fetal outcomes in patients with abnormal and normal LFT were similar. Hyperbilirubinemia and raised alanine aminotransferase (ALT) were significant predictors of maternal mortality.
RESUMO
BACKGROUND: Reversible Cerebral Vasoconstriction Syndrome (RCVS) involves cerebral vasculature constriction and dilation. While the exact pathophysiology of RCVS is still not fully understood, there are multiple etiological factors suggested to be implicated in triggering RCVS. We report two RCVS cases potentially linked to teprotumumab. Case 1: A 59-year-old female with Graves' eye disease (GED) developed leg weakness and headache after initiating teprotumumab, and neuroimaging studies revealed multifocal cerebral vasospasm (CVS). Verapamil mitigated vasospasm and the patient overall improved. Case 2: A 71-year-old female with GED developed thunderclap headache two months after starting teprotumumab, with subarachnoid hemorrhage (SAH) and CVS revealed on neuroimaging studies. The patient improved on verapamil and was discharged without deficits. CONCLUSIONS: The temporal correlation between teprotumumab initiation and RCVS's symptom onset raises concern for the potential involvement of teprotumumab in triggering RCVS via disrupting cerebrovascular modulation. Further research is needed to investigate this proposed association.
RESUMO
Antibiotics are commonly used as antibacterial medications due to their extensive and potent therapeutic properties. However, the overconsumption of these chemicals leads to their accumulation in the human body via the food chain, amplifying drug resistance and compromising immunity, thus presenting a significant hazard to human health. Antibiotics are classified as organic pollutants. Therefore, it is crucial to conduct research on precise methodologies for detecting antibiotics in many substances, including food, pharmaceutical waste, and biological samples like serum and urine. The methodology described in this research paper introduces an innovative technique for producing nanoparticles using silica as the shell material, iron oxide as the core material, and carbon as the shell dopant. By integrating a carbon-doped silica shell, this substance acquires exceptional fluorescence characteristics and a substantial quantum yield value of 80%. By capitalising on this characteristic of the substance, we have effectively constructed a fluorescent sensor that enables accurate ofloxacin analysis, with a detection limit of 1.3 × 10-6 M and a linear range of concentrations from 0 to 120 × 10-6 M. We also evaluated the potential of CSIONPs for OLF detection in blood serum and tap water analysis. The obtained relative standard deviation values were below 3.5%. The percentage of ofloxacin recovery from blood serum ranged from 95.52% to 103.28%, and from 89.9% to 96.0% from tap water.

The sensitivity of fish towards pollutants serves as an excellent tool for the analysis of water pollution. The effluents generated from various anthropogenic activities may contain heavy metals, pesticides, microplastics, and persistent organic pollutants (POPs) and ultimately find its way to aquatic environment. The enzymatic activities of fish collected from water bodies near major cities, oil spillage sites, agricultural land, and intensively industrialized areas have been reported to be significantly impacted in various field studies. These significant alterations in enzymatic activities act as a biomarker for monitoring purposes. The use of biomarkers not only helps in the identification of known and unknown pollutants and their detrimental health impacts, but also identifies the interaction between pollutants and organisms. The conventional method majorly used is physicochemical analysis, which is recognized as the backbone of the system for monitoring water quality. In physicochemical monitoring, major problems exist in assessing or predicting biological effects from chemical or physical data. Xenobiotic-induced enzymatic changes in fish may serve as an intuitive and efficient biomarker for determining contaminants in water bodies. Therefore, field validated biomarker (ValidBIO) approach needs to be integrated in water quality monitoring program for environmental health risk assessment of aquatic life impacted due to various point and non-point sources of water pollution.

Cyclic volatile methyl siloxanes (cVMS) have now become a subject of environmental contamination and risk assessment due to their widespread use and occurrence in different environmental matrices. Due to their exceptional physio-chemical properties, these compounds are diversely used for formulations of consumer products and others implying their continuous and significant release to environmental compartments. This has captured the major attention of the concerned communities on the grounds of potential health hazards to human and biota. The present study aims at comprehensively reviewing its occurrence in air, water, soil, sediments, sludge, dusts, biogas, biosolids, and biota and their environmental behavior as well. Concentrations of cVMS in indoor air and biosolids were higher; however, no significant concentrations were observed in water, soil, and sediments except for wastewaters. No threat to the aquatic organisms has been identified as their concentrations do not exceed the NOEC (maximum no observed effect concentration) thresholds. Mammalian (rodents) toxicity hazards were not very evident except for the occurrence of uterine tumors in very rare cases under long-term chronic and repeated dose exposures in laboratory conditions. Human relevancy to rodents were also not strongly enough established. Therefore, more careful examinations are required to develop stringent weight of evidences in scientific domain and ease the policy making with respect to their production and use so as to combat any environmental consequences.
RESUMO
The usage and the demand for personal protective equipments (PPEs) for our day-to-day survival in this pandemic period of COVID-19 have seen a steep rise which has consequently led to improper disposal and littering. Fragmentation of these PPE units has eventually given way to micro-nano plastics (MNPs) emission in the various environmental matrices and exposure of living organisms to these MNPs has proven to be severely toxic. Numerous factors contribute to the toxicity imparted by these MNPs that mainly include their shape, size, functional groups and their chemical diversity. Even though multiple studies on the impacts of MNPs toxicity are available for other organisms, human cell line studies for various plastic polymers, other than the most common ones namely polyethylene (PE), polystyrene (PS) and polypropylene (PP), are still at their nascent stage and need to be explored more. In this article, we cover a concise review of the literature on the impact of these MNPs in biotic and human systems focusing on the constituents of the PPE units and the additives that are essentially used for their manufacturing. This review will subsequently identify the need to gather scientific evidence at the smaller level to help combat this microplastic pollution and induce a more in-depth understanding of its adverse effect on our existence.
RESUMO
Introduction: Prevalence estimates place maternal heart illness anywhere from 0.3 to 3.5 percent. Up to 20.5% of all maternal deaths of non-obstetrical cause are attributable to cardiovascular disease. Aim: The aim of the study was the management of patients with the multidisciplinary approach to maternal cardiovascular disease and its influence on maternal and fetal outcomes in a tertiary care centre. Objectives: 1. To find out the prevalence and spectrum of heart disease in Pregnancy. 2. To find out the outcome of pregnancy with heart disease in a tertiary care centre. Materials and Methods: This prospective study of one year was done on pregnant with heart disease coming to the Obstetrics and Gynaecology department in collaboration with the cardiology department of IGIMS, Patna. A study was done on 65 pregnant with heart disease between the age group 20 to 35 years were compared to a control group of 65 pregnant women who were hospitalised during the same time period but did not have heart disease. All the pregnant women with heart disease were included in this study. Patients with medical disorders like Kidney disease, Liver disease, Pulmonary Disease, Diabetes Mellitus were excluded from the study. We used IBM's SPSS v23 to analyse the collected data. Result: Prevalence of heart disease in pregnancy was 5.8% in present study and mostly of RHD (62.5%), followed by corrected CHD (12.5%) and CHD (10.9%). Patients of NYHA Class I and II (58.5%), Class III (26.2%), and Class IV (15.4%). The mitral valve was most often impacted by RHD (35.3% of all cases), followed by the tricuspid valve (15.0%). Eight (1.1%) people had cardiac surgery for therapeutic reasons. Six percent of all corrective surgeries included closing an atrial septal defect (ASD). The most common kind of congenital abnormality was a ventricular septal defect (VSD, 3%), followed by atrial septal defect (ASD, 1.5%) and pulmonary ductal atresia (PDA, 1.5%). Patients with heart disease had a higher rate of MTP, emergency LSCS and instrumental births than the controls. Deaths during pregnancy were 4 (6.2%) with cardiac disease and no maternal mortality in control group and all belonged to NYHA Class 4 were anaemic. In patients with a left ventricular ejection fraction of 45% or below, death was high. Two women died intrapartum from RHD, and two died postpartum from Peripartum cardiomyopathy. There were significantly more incidences of low-birth-weight infants (36.4%) compared to the control group (p = 0.001). Cases had a statistically significant greater frequency of obstetric problems, as well as an increased risk of developing anaemia, hypertension, hypothyroidism, cholestasis, FGR, and GDM (p-value 0.017). Multiparity, severe valvular lesion, NYHA function class III or IV, arrhythmia, and low ejection fraction were associated with poor maternal outcome in the current study. Conclusion: Maternal morbidity and mortality due to heart disease can be reduced appreciably by antenatal care, early diagnosis, and management with the help of cardiologists and surgery in selected cases.
RESUMO
Purpose: To assess the efficacy of autologous platelet-rich plasma (PRP) injections in suprachoroidal space and subtenon space in cases of retinitis pigmentosa, which is a genetic disease, leading to gradual loss of vision. Till date, no treatment is available. Methods: Seventy-eight eyes of 39 patients of retinitis pigmentosa having visual acuity ranging from reading of Early Treatment Diabetic Retinopathy Study (ETDRS) chart from 1 m onward to patients who were not able to read the ETDRS chart but whose visual acuity ranged from finger count close to face to <1 m were included in the study. The left and right eyes of each patient were randomized as the intervention eye and control eye. 0.2 mL of autologous PRP was injected in suprachoroidal space and 0.5 mL of PRP was injected in subtenon space of the intervention eye taking aseptic precautions. Injections were repeated at 15-day intervals up to 3 injections. Results: Majority of patients were in the age group of 18-30 years (20 cases) followed by 31-45 years (13 cases) and more than 45 years (6 cases). Intervention eyes showed a statistically significant improvement in visual acuity and multifocal electroretinography (mfERG). Improvement was noted in amplitude density latency and in ring ratio of mfERG. There was a significant improvement in best-corrected visual acuity (BCVA). However, no improvement in mfERG or BCVA was observed in the control group. Conclusions: Gene therapy may be the ultimate cure for retinitis pigmentosa, but it is unaffordable for many patients due to its high cost. PRP may be recognized as a modality to improve vision and stop further deterioration, especially in cases where functional vision is preserved. Negligible treatment costs and affordability will give power to economically disadvantaged patients.
RESUMO
Coronavirus disease 2019 (COVID-19) vaccine side effects have an important role in the hesitancy of the general population toward vaccine administration. Another reason for vaccine hesitancy might be that healthcare professionals may not address their concerns regarding vaccines appropriately. Regardless, hesitancy in the form of delay, refusal, or acceptance with doubts about its usefulness can limit the downward trajectory of the COVID-19 pandemic. Therefore, the authors conducted a national cross-sectional study (n=306) to assess causes and concerns for vaccine hesitancy in caregivers in Pakistan toward getting their children vaccinated. The questions identified caregivers by socioeconomic demographics, perceived COVID-19 pandemic severity, and concerns toward the COVID-19 vaccine. The majority of the participants were 45-59 years of age (42.8%) with a mean age of 36.11 years (SD: 7.81). A total of 80% of these participants were willing to vaccinate their child with any COVID-19 vaccine. Present comorbidities had a frequency of 28.4% (n=87/306) and only 26.9% (n=66/245) participants were willing to vaccinate their child. Participants with high social standing were 15.4% (n=47/306) with the majority of them being willing to vaccinate their children (45/47). Socioeconomic status (OR:2.911 [0.999-8.483]), and the child's vaccinations being up to date (OR:1.904 [1.078-3.365]) were found to be independent factors for caregivers to be willing to vaccinate their child. Around 62% (n=191/306) were not willing to vaccinate due to the concern for side effects, 67.6% (n=207/306) were not willing because they did not have ample information available, and 51% (n=156/306) were not willing as they were concerned about vaccine effectiveness. Further studies on vaccine safety in the pediatric population are required to improve caregivers' perceptions.
RESUMO
Black soldier fly (Hermetia illucens L. [Diptera: Stratiomyidae]) has gained huge popularity in different industrial and commercial sectors because of its excellent potential to treat organic waste and high biomass production. As the industrial application of BSF is expanding at accelerated rates, there is a need to optimize its mass scale production where the organic substrates play a very crucial role in optimal growth and development. The present study deals with the investigation of different life history attributes of BSF such as larval and adult weights, survival, pupation rate, and the development time as the function of different organic substrates [fruits and vegetable mix (T1); wheat bran, soy, and corn meal mix (T2); and the dairy manure (T3)]. The larval, pupal, and adult weights differed across all three treatments (P < 0.05). There was no significant difference in the survival rate of larvae among T1 and T2 however, T3 differed significantly from T1 and T2. Likewise, the pupation rate and the development time differed significantly between the three treatments. Results indicated that the BSF development was least in dairy manure treatment and therefore, higher percent mortality and higher development time were observed. However, to deal with the problems of waste management and treatment, BSF larvae can be successfully employed for the treatment of any type of waste since it showed significant treatment efficiencies.
