The Presence of Minority HIV Drug Resistance Variants in The Protease and Gag Regions Confers Poor Response to Therapy Among Subtype A And D Patients

Objective: To determine the prevalence of minority drug resistance variants in the protease and Gag regions among patients failing a protease inhibitor (PI) based regimen with or without a susceptible genotype based on Sanger sequencing technology. Methods: Samples were obtained from patients who were failing on a protease inhibitor-based regimen (n = 500). Sanger based sequencing was performed as part of the standard of care. Mutation analysis was performed using the Stanford HIV drug Resistance database. A subset of these patient samples was grouped into two categories: those failing a PI based with mutations in the protease region (n = 100) and those failing on a PI based regimen without mutations in the protease region (n = 128). These samples were then analyzed in the protease and Gag regions using Next Generation Sequencing (NGS) technology and analysis of the drug resistance mutations was performed at the 20% and 1% cutoffs. Results: An initial analysis of the protease region for patients failing with drug resistance mutations revealed that most patients harbored mutations that confer resistance to Lopinavir and Atazanavir, but these mutations had little effect on Darunavir. Furthermore, NGS revealed that in patients failing with and without drug resistance mutations, minority drug resistance mutations were present at each of the drug resistance codons and at codons that confer multi-drug resistance to protease inhibitors. Further analysis of the Gag gene revealed more genetic diversity among patients failing with no mutations in the protease as evidenced by the proportion of polymorphisms at each codon. Conclusion: Based on Sanger sequencing, a proportion of patients fail a PI based regimen with a susceptible genotype. However, these patients harbor minority variants in the protease and numerous polymorphisms in the Gag region which when combined these could explain their poor response to therapy. Therefore, in order to improve patient care in low resource settings, there is need to adapt NGS as the standard genotyping technique so that minority variants are captured much earlier. In addition, since mutations in the Gag region also play a role in response to PIs, this region should be included in the routine monitoring for response to therapy in patients on a PI based regimen.

Effects of Gabapentin Enacarbil on Cortical Arousals, Heart Rate, Blood Pressure and Anterior Tibialis EMG Responses Associated with PLMs in Restless Legs Syndrome

Objective: This study was conducted to investigate the effects of gabapentin enacarbil (GEn) on sleep EEG, heart rate (HR), blood presssure, anterior tibialis EMG activity (PLMs power) and subjective complaints in subjects with moderate to severe RLS and disturbed sleep. Methods: This was a single site, single-blind, placebo run-in, fixed dose single group polysomnography (PSG) study. Eligible subjects (age 24-66 years) were treated with placebo for one week and GEn (600 mg/day) for 4 weeks. Two in-laboratory PSGs were collected for adaptation and baseline at the end of the placebo run-in period and for re-adaptation and efficacy assessment at the end of the 4-week treatment period. The primary endpoint was the difference in PSG derived cortical arousal intensity (arousal scale, 0-9) associated with PLMs between 4 weeks of treatment with GEn and placebo. Secondary endpoints included changes in HR responses (ΔHR), nocturnal systolic blood pressure (SBP) changes (>10 mmHg) secondary to PLMs and PLMs power. Other PSG and subjective measures were assessed. Results: Of 20 subjects enrolled, 18 completed the study. Subjects treated with GEn did not show significant improvements in cortical arousal intensity and ΔHR. However, subjects showed reduced PLMs power (p= 0.013) and associated reductions in nocturnal SBP per hour of sleep (p= 0.041) GEn showed significant improvement in other PSG parameters and subjective endpoints. Conclusion: The data suggests that GEn reduces the frequency and power of PLMs and the corresponding SBP changes in subjects with RLS. Despite reducing the total number of PLM associated arousals and nocturnal HR, the study did not demonstrate consistent effects of GEn on cortical arousal intensity and corresponding HR changes associated with PLMs. Clinical Trial Registration: identifier: NCT02424695

Genomic Asymmetry for Morphology in Allopolyploids within and Out of Brassica

The genomic asymmetry in the nonrandom retention and expression of controlling genes for some traits from one parental diploid is obvious in some natural and synthetic allopolyploids, and has the evolutionary implications. Here we review the genomic asymmetry for the morphological performance in three cultivated Brassica allotetraploids and some intergeneric allopolyploids within Brassicaceae species. For the phenotypic biases of Brassica allotetraploids, Brassica oleracea (genomes CC) is dominant over B. nigra (BB) and B. rapa (AA) in B. carinata (CCBB) and B. napus (CCAA), respectively, and B. nigra is dominant over B. rapa in B. juncea (BBAA), showing the C>B>A dominance hierarchy.

Eco Safe Assimilation of Plastic Wastes by Microbes and Biodegradable Alternatives: A Review

Lack of degradability and the closing of landfill sites as well as growing water and land pollution problems have led to concern about plastics. In the past few decades, the use of plastics has enormously increased, mostly used for food packaging. Ironically, the most preferred property of plastics – durability – exerts also the major environmental threat. With the excessive use of plastics and increasing pressure being placed on capacities available for plastic waste disposal, the need for biodegradable plastics and biodegradation of plastic wastes has assumed increasing importance in the last few years.

Increased expression of Nppc and Npr2 in ovarian tissues from mice with polycystic ovary syndrome

Weight loss is an efficient therapy for obese polycystic ovary syndrome (PCOS) patients. Here we evaluate the effect of dietary weight reduction on clinical performance in obese PCOS patients. Medical records of fifty obese PCOS patients (age 27 ± 5 years) who had calorie-controlled dietary intervention were reviewed. The patients had a 1200-kcal/day diet until ovulation or for up to three months. Changes in body weight, body mass index (BMI), blood pressure, menstruation, acne, and hirsutusm, serum levels of endocrine hormones and adipocytokines, glucolipid metabolism index and insulin resistance were assessed. Menstrual cycle, ovulation andrelapse in the following six months were also reviewed. All patients had menstrual disorder, 43 had acne, and 26 were hirsute. After weight loss, the BMI decreased from 27.89 ± 3.06 to 25.70 ± 2.42 kg/m2 (p < 0.001). Acne and hirsutusm was improved in 39 and 14 patients, respectively. Regular menstruation was restored in 26 patients and lasted for 3.12 months on average. Endocrine hormones levels, adipocytokines levels, glucolipid metabolism and insulin resistance were shifted toward balance. Weight relapse was seen in 11 patients. No side effects occurred. Dietary intervention in obese PCOS patients can improve relevant clinical problems but weight relapse is an issue

Evaluating the Economic Performance of Reverse Polymerization Technology for Waste Tyre Recycling in Sub-Saharan Africa

The unlawful and uncontrolled disposal of waste tyres is greatly disturbing in terms of the environmental concerns and the economic misfortune. In combating this menace, there is growing interest in the application of efficient and environmental-friendly alternatives to the traditional recycling methods for waste tyres. Pyrolysis can be considered as an appropriate non-conventional method for complex materials such as tyres. Several works have been made to improve pyrolysis process towards higher yield and quality of biofuels and greater energy efficiency. This study considers Reverse Polymerization, a microwave-assisted pyrolysis process to extract complete yield and higher quality of valuable products, while avoiding toxic emissions into the environment. The feasibility of such innovative recycling process in Sub-Sahara Africa is essential in order to convince concerned authorities to buy into such advanced technologies with great benefits. The investment analysis and economic performance indicators from the study demonstrated that the operation of such proposed recycling system in the continent is economically feasible. However, the operation of such facility under the present market conditions might highly be challenged by high investment risk as the project is highly capital intensive.

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.
