The global endeavor to develop and deploy COVID-19 vaccines has underscored both significant scientific progress and enduring disparities in worldwide access. This analysis examines regional vaccine distribution patterns across World Health Organization (WHO) regions—Africa, the Americas, Eastern Mediterranean, Europe, and Western Pacific—revealing substantial variations in vaccine types and manufacturer contributions. Data indicate that the Americas and Europe demonstrate a broad vaccine portfolio, with prominent contributions from major international pharmaceutical companies alongside regionally developed vaccines. Conversely, African, Eastern Mediterranean, and Western Pacific regions show considerable reliance on vaccines from Asian (notably China and India) and Russian manufacturers, in addition to Western products. This distribution highlights the influence of geographical proximity to manufacturing centers, regional alliances, and local production capabilities (e.g., CIGB and Finlay in the Americas, COVIran Barakat in the Eastern Mediterranean, and various Chinese products in the Western Pacific) on vaccine availability. Predominant vaccines by country count include Pfizer-BioNTech's Comirnaty, AstraZeneca's Vaxzevria, Janssen's Ad26.COV2-S, Moderna's Spikevax, Beijing CNBG's BBIBP-CorV, and SII's Covishield. The observed regional variations in vaccine types and supply chains carry implications for comparative effectiveness research, the understanding of differential immune responses, and the evaluation of pandemic control strategies. Furthermore, inconsistencies in global data reporting and product nomenclature present challenges for comprehensive analysis. The findings emphasize the importance of diversified supply chains, the growing role of regional manufacturing in enhancing global health security, and the need for standardized global data for a more profound understanding of vaccine equity and efficacy to inform future pandemic responses.

Elevated arterial blood pressure is the most important public health problem in developed countries. It often leads to lethal complications if left untreated. Brewer's yeast is celebrated for its various beneficial effects, including a possible hypotensive effect. Thus, the anti-hypertensive effects of brewer’s yeast were investigated. The hypertensive model was done by a once-weekly intraperitoneal injection of dexamethasone at a dose of 25 mg/kg combined with drinking a 1.0% sodium chloride solution containing 0.2% KCl and 2.0% glucose for six weeks. The blood pressure was measured by the rat carotid artery cannulation preparation. Different doses of brewer's yeast dissolved in distilled water were injected into the internal jugular vein, with measurement of blood pressure at each time. To explore the mechanism of the hypotensive effect of yeast, the yeast cardiac effect was verified by the use of isolated perfused rabbit heart preparations using different antagonists. It was found that dexamethasone elevated systolic blood pressure to 178.3±11.6 and diastolic blood pressure to 133.3±16.6 from normal levels of 115.0±9.1 for systolic and 74.0±4.1 for diastolic. The gradual increase in intravenous yeast doses ranging from 0.05 to 0.40 effectively lowered systolic and diastolic blood pressure in rats with normal pressure, bringing them to approximately 80.0±05.6 mmHg for systolic and 40.0±3.5 mmHg for diastolic. While doses exceeding 0.04 resulted in a drop in systolic pressure to 60.0±3.9 mmHg, diastolic pressure became unrecordable. The administration of the 0.20 dose resulted in unrecordable blood pressure. In hypertensive rats, a decrease in blood pressure was observed with doses ranging from 0.60-1.0 mg, leading to a reduction to 110.0±2.8 mmHg for systolic and 52.0±9.9 mmHg for diastolic pressures. Doses exceeding 1.0 mg further lowered systolic and diastolic pressures to 20.0±3.9 mmHg. There was a mild increase in heart rate with no change in cardiac force of contraction. This effect was not mediated through beta, calcium receptors, or the histamine effect. The findings show that the yeast has a dose-dependent blood pressure-lowering effect. The mechanism of the chronotropic effect is possibly due to its direct action.

For thousands of years, lipid based Ayurvedic formulations have been made in India, and the craft has survived down the millennia up to the present time. Some of these deliciously potent phytonutrient preparations are very popular and have sustained the test of time pertaining to their efficacy. Recent researches on the role of phytonutrients in promoting cardio-pulmonary, brain and immune health substantially buttress the philosophy underlying the use of lipids in preparing these emulsions, since a large number of these bioactives are lipophilic. Being lipoidic, they are absorbed through the lacteals in the small intestine, and are then transported through the thoracic duct directly to the heart, bypassing the liver. The formulations utilizing ghee (clarified butter) or sesame oil as the carrier lipid, either while frying the myrobalams or as Anupana (adjuvant), have special significance in modulating bodily immunity, since the immune system is housed in lymphatics which are lipid rich. Amla and lipid based Ayurvedic rasayans (rejuvenating formulations) are a popular and highly palatable group of phytonutraceutical preparations. This group of polyherbal adaptogenic formulations is classified separately from other formulations in Ayurvedic therapeutics. Several of these healthpromoting rasayans are suitable to be consumed by all age-groups in the recommended season and dose. Current research on endothelial and immune cell receptor mediated uptake of lipoidic molecules, together with the knowledge of lipid absorption pathways, lends credence to the usefulness of rasayans in targeting the cardio-pulmonary and immune systems. An attempt has been made in this paper to elucidate the mechanisms underpinning the complex interplay between lipid delivered hydrophobic phyto-molecules, systemic lymphatics and the Immune system.

Epithelial cells, lining the skin and internal organs, play a crucial role as protective barriers and regulators of substance transport. Traditionally, these cells were not considered to employ electrical signaling for communication. However, recent investigations have unveiled that epithelial cells generate slow electrical signals, termed the "silent scream," in response to injury, thus challenging conventional views of intercellular communication. A recent experimental investigation provided compelling evidence for this phenomenon, demonstrating the ability of these cells to transmit electrical signals over considerable distances within the epithelium. The research utilized microelectrode array chips to precisely detect subtle electrical events in keratinocytes and Madin-Darby Canine Kidney (MDCK) cells, revealing spiking activity characterized by slow propagation speeds, distinct from the rapid action potentials of neurons. The mechanisms underlying this novel signaling are explored, focusing on the involvement of mechanosensitive ion channels, calcium signaling, and Adenosine triphosphate (ATP) release. Calcium ions, well-established intracellular messengers, appear to play a central role in this biological phenomenon. Integrating this newly discovered communication mode into the existing understanding of skin cell biology reveals a more intricate picture of how skin senses and responds to its environment. The implications of this finding extend to various facets of skin physiology and pathology, including wound healing, inflammation, and skin aging. In wound healing, where endogenous electric fields guide cell migration and promote repair, this unique type of electrical signaling potentially plays a crucial part. Furthermore, aberrant electrical signaling might contribute to chronic inflammatory conditions, and age-related changes in this signaling could underlie the functional decline observed in aged skin. The potential for other environmental stressors to trigger the epithelial-generated electric signals also warrants investigation. The exploration concludes by discussing potential technological applications, such as bioelectric sensors and enhanced wound healing therapies, and future research directions aimed at further elucidating the molecular mechanisms and functional roles of this non-excitable cell electrophysiology.

This study's objective was to determine the distribution of allele frequencies of CYP2C9 and CYP2C19 gene polymorphisms among the Papuan population, known as the second-largest ethnic group in Indonesia. According to recent research, there is a decrease in CYP2C9 and CYP2C19 produced by humans globally, including in Indonesia. These gene polymorphisms aid in the transmission of various endogenous and exogenous drugs in the human body. Material and Methods: A sum of 99 subjects, comprising 73 male and 26 female subjects aged 20-30 years, were used for this research. PCR-RFLP (polymerase chain reaction-restriction fragment length polymorphism) analysis using AvaII, NsiI, and SfaNI enzymes tested for the genotypes CYP2C9 and CYP2C19 administered. The distribution of genotypes was calculated in the population (P<0.05) using the Hardy-Weinberg equilibrium. The Faculty of Medicine Gadjah Mada University's Medical and Health Research Ethics Committee (MHREC) accepted this research with written consent. The results revealed that in Papua subjects, CYP2C9*2 (rs1799853) and CYP2C19*17 (rs12248560) alleles were absent while in 17 percent of the population CYP2C9*3 (rs1057910) allele frequency was. In conclusion, CYP2C9*3 has the highest polymorphism rate in Indonesia, with the absence of CYP2C9*2 and CYP2C19*17. Therefore, genetic drift can occur within this ethnic group.

The most successful and cost effective method for control the COVID-19 pandemic is the vaccination. Currently, there are different COVID-19 vaccine introduced into Libyan market. This study aimed to evaluate and compare the acceptance of COVID-19 vaccine among general population and students in Benghazi city. A cross sectional survey was conducted during March 2021 among 440 respondents (240 general populations and 200 students) using a self-administered questionnaire. The results were considerably similar among the two groups of participants. Only 10.9% said that they infected with COVID-19 during the pandemic period. About two thirds of the respondents agreed to be vaccinated against COVID-19 when available whereas the majority said they would wait some time before taking the vaccine (71.4%). Approximately, one third of the participants preferred the Sputnik vaccine, 24% preferred the Pfizer and BioNTech and 19.2% preferred Oxford (AstraZeneca) vaccine. More than a half (55.9%) of the participants are refused to pay for the vaccine. The majority of the respondents do not think the vaccine alone will be enough in protection against the COVID-19 (79.8%). There was no significant association between general population, students and the COVID-19 vaccine acceptance (p = 0.776). Additionally, there was no significant correlations between socio-demographic data and attitudes of the respondents with the acceptance of COVID-19 vaccine (p > 0.05), except for using hand sanitizers daily was significantly associated among the general population (p = 0.008). In conclusion, although, the general population and students have a good acceptability to the COVID-19 vaccine, more education health programs and promotion are wanted to reduce the vaccine hesitancy by declaring the importance of the vaccine, showing sufficient data stabilize the vaccine safety.

Scholars who apply artificial intelligence to political questions seek, most generally, to expand the scope and relevance of political model analysis. By incorporating the effects of variable human notions, traditions, and meanings, they seek to humanize political models. Most early applications of artificial intelligence in political science research address substantive issues pertaining to political decision making. Most of these works apply production-system technology to construct choice models in for eign-policy decision contexts. In recent years, political applications have begun to diver sify. Today, lively research efforts flourish in widely varied application areas, such as computational text analysis, logic programming, computer learning, and conflict sim ulation. The works reviewed here constitute the early steps of a nascent program of study. Much remains to be accomplished. Nevertheless, the efforts conducted thus far suggest many potentially fruitful research avenues. Youth are the most essential and promising segment of every country’s population.

The incorporation of lomustine, a hydrophobic anticancer drug into PLGA nanoparticles by interfacial deposition method was optimized. Based on the optimal parameters, it was found that lomustine-PLGA nanoparticles with acceptable properties could be obtained. Optimization of formulation variables to control the size and drug entrapment efficiency of the prepared nanoparticles seems to be based on the same scientific principles as drug-loaded nanoparticles prepared by nanoprecipitation, solvent evaporation method. The process was the most important factor to control the particle size, while both the drug-polymer interaction and the partition of drug in organic and aqueous phases were the crucial factors to govern the drug entrapment efficiency. PLGA concentration at lower level (100 mg), 1:5 organic phase: aqueous ratio, 1%w/v PVA concentration, 3%w/v pluronic F68 achieved smaller particle size. Additionally, L:G ratio of PLGA 75:25, lower volume of organic solvent (1:10 organic phase: aqueous phase), higher initial drug content (10mg) enhanced the drug entrapment efficiency and maintained lomustine concentration in blood for an extended time period, elevated lomustine concentration in lungs and slowed the elimination of lomustine. The biodistribution profiles of prepared nanoparticles in albino mice showed higher plasma drug concentration for longer period of time, elevated drug concentration in lungs and slow elimination from kidney. No toxic effects of prepared nanoparticles were observed in histopathological examination of lungs and kidney. The systematic investigation reported here promises the development of PLGA nanoparticles loaded with lomustine when tested in Lung Cancer cell line L132 and toxicological/ histopathological studies in albino mice.

Industrial waste is one of the most essential sources of contamination in the environment. Chromium (Cr) is a toxic heavy metal, a major contaminant in tannery wastes and its accumulation in soil and water is a major environmental concern today. In the present study, an attempt was made and investigated the status of different beneficial microbes particularly plant growth promoting rhizobacteria (PGPR) from tannery sludge samples collected from tannery effluent treatment plant at Dindugal, Tamil Nadu, India. Experiments were conducted and evaluated their chromium heavy metal tolerance abilities and plant growth promoting activities under in-vitro. Based on molecular analysis, the PGPRs were identified as Achromobacter xylosoxidans (LK391696), Azotobacter vinelandii (LK391702) and. The production of IAA was found to be high by Achromobacter xylosoxidans (46μg/ml) followed by Azospirillum lipoferum (30μg/ml). Phosphate solublization activity was also found to be positive in all these PGPR isolates. Significance of these results revealed that there is a possibility of using these potential PGPRs for bioremediation of chromium contaminated sites and also as good plant growth promoter.

Background: Preterm birth remains a leading cause of neonatal morbidity and mortality worldwide. Identifying its risk factors is essential for developing targeted interventions to improve maternal and neonatal health. This study investigated the sociodemographic, obstetric, medical, and lifestyle risk factors associated with preterm birth among women who delivered at Abia State University Teaching Hospital (ABSUTH), Aba, Southeast Nigeria. Methods: A hospital-based case-control study was conducted at ABSUTH. The study population comprised all the women who gave birth at the facility who met the criteria. Data were collected through structured interviewer-administered questionnaires and medical record reviews. Key variables included maternal age, education level, socioeconomic status, obstetric history, medical conditions, lifestyle factors, and antenatal care utilization. Descriptive statistics, chi-square tests, t-tests, and logistic regression were performed using SPSS version 25, with statistical significance set at p < 0.05. Results: A total of 9125 deliveries were recorded during the period of this study, including 1,962 cases (preterm births, <37 weeks gestation) and 7,163 controls (term births, ≥37 weeks gestation). Chi-square analysis showed significant associations between preterm birth and maternal age (p < 0.05), low education level (p < 0.001), low socioeconomic status (p = 0.0351), previous preterm birth (p < 0.001), short pregnancy interval (p < 0.001), hypertension (p < 0.001), diabetes (p < 0.001), infections (p < 0.001), smoking (p < 0.001), alcohol consumption (p < 0.001), and inadequate antenatal visits (p < 0.001). Logistic regression confirmed that hypertension, diabetes, infections, previous preterm birth, and inadequate antenatal visits were independent predictors of preterm birth. Conclusion: The findings highlight the multifactorial nature of preterm birth, with medical conditions, lifestyle behaviors, and inadequate antenatal care playing crucial roles. Early identification and management of these risk factors through improved maternal health services and health education may reduce the burden of preterm birth in the study setting.
