The effects of severe hypobaric hypoxia and inhibition of hypoxia-inducible factor-1 (hif-1) on biomarkers of cardiac and skeletal muscle injury in rats

The goal of the present study was to investigate the molecular mechanisms that underlie heart andskeletal muscle damage in male Wistar rats weighing 200–250 g in response to a 3-h exposure to 180 mm Hg(5% O2) in the model of severe hypobaric hypoxia. It has been demonstrated that the level of the cardiac bio-marker troponin I in the blood plasma of rats exposed to severe hypobaric hypoxia for 3 h increased signifi-cantly compared to the control group, indicating myocardial injury. At the same time, the administration ofthe HIF-1α transcription factor inhibitor did not affect the plasma level of troponin I. In contrast, the releaseof the non-specific biomarker myoglobin into the bloodstream did not increase in response to hypoxia com-pared to the control animals. In addition, 24 h after the exposure to severe hypobaric hypoxia the serum myo-globin level was significantly lower in animals administered with the HIF-1α inhibitor topotecan than in ratsthat did not receive topotecan. Therefore, it may be assumed that the inhibition of the HIF-1α transcriptionfactor 10 min before exposure to severe hypobaric hypoxia reduces skeletal muscle damage. The mechanismsthat affect the adaptation of heart and skeletal muscles to hypoxia are discussed.

Aqueous extract of hybanthus enneaspermus exhibited aphrodisiac potentials in fluoxetine-induced sexually-impaired female rats

Hybanthus enneaspermus, traditionally used as an aphrodisiac was investigated for its potential to reverse antidepressant-induced sexual dysfunction in female rats. The aqueous extract was evaluated for secondary metabolite, amino acid and mineral constituents. Alkaloids, tannins, flavonoids, anthraquinones, steroids, terpenoids, phenolics, calcium, potassium, sodium, glutamine and leucine are some of its notable constituents. 60 healthy, sexually responsive female albino rats (144.7±5.9 gm) were divided into six groups (A-F) of 10 rats each; of which 50 were induced into sexual dysfunction. Rats in group A were administered distilled water throughout the experimental period and served as a control group, while rats induced into sexual dysfunction (Groups B-F) by fluoxetine were given water, the reference medication (Tadalafil) and oral doses of the extract (250, 500, and 1000 mg/kg body weight) once daily for seven days, respectively. When administered to sexually active rats, fluoxetine significantly decreased the frequency of darting, hopping, lordosis, genital grooming, and licking behavior by 57.4%, 42.5%, 43.9%, 64.0%, and 41.8%, respectively. However, the latency of darting, hopping and lordosis were significantly increased by 50.6%, 47.7%, and 54.9%, respectively. Hybanthus enneaspermus aqueous extract administered at doses of 250, 500, and 1000 mg/kg significantly reversed fluoxetine-mediated changes in all sexual behavior parameters. The extract's ability to reverse the characteristics of sexual behavior at 1000 mg/kg was comparable to those of tadalafil-treated rats. Additionally, all the extract dosages reversed the levels of blood luteinizing hormone, follicle-stimulating hormone, progesterone, prolactin and estrogen after it has significantly been altered by fluoxetine. The results indicated that the aqueous extract of Hybanthus enneaspermus improved the proceptive, receptive and orientational behavior of rats. The extract also enhanced reproductive hormone concentration by restoring sexual competence in sexually-impaired female rats. The findings of this study provide further evidence in favor of Hybanthus enneaspermus widespread usage in the management of female sexual dysfunction.

Prevalence and associated factors of overweight and obesity among persons with type 2 diabetes in africa: a systematic review and meta-analysis

Background Type 2 diabetes and obesity are serious public health concerns globally and a growing burden in Africa. Both conditions have serious repercussions on health when they co-occur, yet the extent of their co-occurrence in Africa remains unknown. Therefore, this review aimed to identify the prevalence and associated factors of overweight and obesity among persons with type 2 diabetes in Africa. Method A systematic search was conducted on PubMed, MEDLINE, Embase, African Index Medicus (AIM), and African Journals Online (AJOL) for observational studies that reported the prevalence of overweight and/or obesity among type 2 diabetes patients in Africa. The prevalence data from individual studies were aggregated through a random-effects meta-analysis. The I2 statistic was used to evaluate between-studies heterogeneity, while subgroup analysis and mixed-effects meta-regression were performed to identify sources of heterogeneity. We assessed publication bias using funnel plots and Egger’s test. This review adhered to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Results Of 1753 records retrieved, 80 articles were eligible for this review, with 74 cross-sectional studies included in the meta-analysis. The pooled prevalence of overweight and obesity was 35.6% and 25.6% respectively, while the overall prevalence of both overweight and obesity was 61.4%. Also, the pooled prevalence of both overweight and obesity across the five geographical areas in Africa ranged from 56.9% in East Africa to 88.5% in Southern Africa. Nineteen factors were significantly associated with overweight and obesity among patients with type 2 diabetes. Conclusion The high prevalence of overweight and obesity among patients with type 2 diabetes is a significant public health concern that transcends geographical boundaries within Africa. The findings from this review highlight the need for innovative weight management interventions that are tailored to the cultural context of the African setting

Two-phase flow in microfluidic-chip design of hydrodynamic filtration for cell particle sorting

As one of the flow-based passive sorting, the hydrodynamic filtration using a microfluidic-chip has shown to effectively separate into different sizes of subpopulations from cell or particle suspensions. Its model framework involving two-phase Newtonian or generalized Newtonian fluid (GNF) was developed, by performing the complete analysis of laminar flow and complicated networks of main and multiple branch channels. To predict rigorously what occurs in flow fields, we estimated pressure drop, velocity profile, and the ratio of the flow fraction at each branch point, in which the analytical model was validated with numerical flow simulations. As a model fluid of the GNF, polysaccharide solution based on Carreau type was examined. The objective parameters aiming practical channel design include the number of the branches and the length of narrow section of each branch for arbitrary conditions. The flow fraction and the number of branches are distinctly affected by the viscosity ratio between feed and side flows. As the side flow becomes more viscous, the flow fraction increases but the number of branches decreases, which enables a compact chip designed with fewer branches being operated under the same throughput. Hence, our rational design analysis indicates the significance of constitutive properties of each stream.

Prevalence of acute infectious hepatitis in eastern libyan pediatrics

Viral hepatitis is one of the main public health concerns around the world. Even though infection management techniques have been implemented over the last few decades, eradication or significant reduction has remained a mystery. The purpose of this study is to look into the prevalence of acute infectious hepatitis in the East of Libya and how the type of virus, age, gender, clinical manifestations, and outcome are related. This is a hospital-based retrospective study. The data on the frequency and distribution of viral hepatitis based on age, gender, seasonal, clinical, and ultrasound findings, and the outcomes during a period of two years from January 2020 to December 2021 were collected and analyzed. Of the 0.39% (72 cases) of total hospital admissions (18340) under the age of 15 years old for acute infectious hepatitis patients, the most common age group was 5-12 years (79.6%). Winter accounted for 41.6% of all the cases. Females made up 65.3% of the cases. Jaundice was the most prevalent presentation (87.5%). Hepatomegaly was seen in 83.3% of the patients. Most of the cases have mild hyperbilirubinemia (5-9 mg/dL, 75.0%). Approximately 1/5th of the patients' serum glutamic-oxaloacetic transaminase (SGPT), and nearly 1/3rd of the patients' SGPT levels were in the range of 1000-2000. One patient's hepatitis C was positive, one patient's hepatitis B was positive, and 97.2% were positive for hepatitis A. 88.8% of the individuals recovered without complications, whereas 11.1% showed symptoms of hepatic failure but recovered. The present study indicates that acute hepatitis A is more prevalent, especially in the winter. Those who are females and 5-12 years of age were more affected by acute viral hepatitis in Libya.

Application of amorphous zirconium (hydr)oxide/mgfe layered double hydroxides composite in fixed-bed column for phosphate removal from water

BACKGROUND AND OBJECTIVES: Fixed-bed column has been considered an industrially feasible technique for phosphate removal from water. Besides the adsorption capacity, the effectiveness of an adsorbent is also determined by its reusability efficiency. In this study, phosphate removal by a synthesized amorphous zirconium (hydr)oxide/MgFe layered double hydroxides composite in a fixed-bed column system was examined. METHODS: The effects of flow rate, bed height, phosphate concentration, solution pH, and adsorbent particle size on the phosphate adsorption ability were examined through a series of continuous adsorption experiments. The appropriate breakthrough curve models, phosphate adsorption from real anaerobic sludge and synthetic seawater, column regeneration and reusability, and adsorption mechanism were also investigated for practical application feasibility. FINDINGS: The results showed that the increased bed height and phosphate concentration, and reduced flow rate, pH, and adsorbent particle size were found to increase the column adsorption capacity. The optimum adsorption capacity of 25.15 mg-P/g was obtained at pH 4. The coexistence of seawater ions had a positive effect on the phosphate adsorption capacity of the composite. Nearly complete phosphate desorption, with a desorption efficiency of 91.7%, could be effectively achieved by 0.1 N NaOH for an hour. Moreover, the initial adsorption capacity was maintained at approximately 83% even after eight adsorption-desorption cycles, indicating that the composite is economically feasible. The high phosphate adsorption capacity of the composite involves three main adsorption mechanisms, which are electrostatic attraction, inner-sphere complexation, and anion exchange, where the amorphous zirconium hydr(oxide) on the surface of the layered double hydroxides likely increased the number of active binding sites and surface area for adsorption. CONCLUSION: The amorphous zirconium (hydr)oxide/MgFe layered double hydroxides composite, with its high adsorption capacity and superior reusability, has the potential to be utilized as an adsorbent for phosphorus removal in practical wastewater treatment. This study provides insights into the design of amorphous zirconium (hydr)oxide/MgFe layered double hydroxides composite for phosphorus removal and recovery in a practical system.

Influence of demographic and socio-economic factors on locus of control on residents of select suburbs in mumbai city

The orientation he/she chooses has a bearing on his/her long-term success. This orientation is known as your "locus of control." Its study dates back to the 1960s, with Julian Rotter's investigation into how people's behaviours and attitudes affected the outcomes of their lives. Locus of control has been defined as the degree to which an individual perceives having control over the environment (Rotter, 1966). According to Rotter (1975), there are two types of control, internal and external, which anchor a continuum that approximates a normal distribution. People are said to have an internal locus of control when they believe reinforcements are contingent upon their own behaviour or stable personal characteristics. External locus of control results when people believe that reinforcements are due to luck, fate, or powerful others outside of their control. Current study focuses on investigating the influence of demographic variables (age, gender, education level), marital status and socio economic status (occupation, income) on the level of internal/ external locus of control with the help of data collected from residents (aged between 20 and 50) of a select suburbs in Mumbai city. On analysing the data so collected, it is found that age has a major influence on an individual’s level of internal locus of control.

Slu-pp-332 and related errα agonists: a focused minireview of metabolic regulation, and therapeutic potential

The global burden of metabolic disorders, including obesity and type 2 diabetes, necessitates innovative therapeutic strategies. SLU-PP-332, a synthetic agonist of estrogen-related receptor α (ERRα), has emerged as a promising exercise mimetic, demonstrating preclinical efficacy in enhancing mitochondrial biogenesis, insulin sensitivity, and energy expenditure. This brief review synthesizes current knowledge on SLU-PP-332 and related ERRα agonists, highlighting their molecular mechanisms, preclinical outcomes, translational challenges, and ethical considerations. ERRα activation by SLU-PP-332 upregulates peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1α), driving fatty acid oxidation and mimicking exercise-induced metabolic adaptations. However, pan-ERR activity raises concerns about off-target effects such as cardiac hypertrophy and hepatotoxicity. Despite robust preclinical data, clinical translation remains hindered by the absence of human trials and undefined long-term safety. Future research must prioritize isoform-selective agonist design, rigorous clinical validation, and equitable access frameworks.

Live bird markets in nigeria: a potential reservoir for h9n2 avian influenza viruses

Since 2006, multiple outbreaks of avian influenza (AI) have been reported in Nigeria involving different subtypes. Surveillance and molecular epidemiology have revealed the vital role of live bird markets (LBMs) in the dissemination of AI virus to commercial poultry farms. To better understand the ecology and epidemiology of AI in Nigeria, we performed whole-genome sequencing of nineteen H9N2 viruses recovered, from apparently healthy poultry species, during active surveillance conducted in nine LBMs across Nigeria in 2019. Analyses of the HA gene segment of these viruses showed that the H9N2 strains belong to the G1 lineage, which has zoonotic potential, and are clustered with contemporary H9N2 identified in Africa between 2016 and 2020. We observed two distinct clusters of H9N2 viruses in Nigeria, suggesting different introductions into the country. In view of the zoonotic potential of H9N2 and the co-circulation of multiple subtypes of AI virus in Nigeria, continuous monitoring of the LBMs across the country and molecular characterization of AIVs identified is advocated to mitigate economic losses and public health threats.
