Correlation between Oxidative Stress and Thyroid Function in Patients with Nephrotic Syndrome

Background. The present study is to look for a correlation between oxidative stress and thyroid function in patients with the nephrotic syndrome in the remission phase as well as in a persistent proteinuric state. Introduction. Nephrotic syndrome is a form of chronic kidney disease due to which blood loses protein through the urine. We wanted to know if there was an increased loss of thyroid hormones in urine affecting thyroid function. Methods. 60 patients with nephrotic syndrome and 20 healthy non-proteinuric individuals as control subjects were enrolled in the study. We measured their serum tri-iodothyronine, thyroxine and thyroid-stimulating hormone. Estimation of lipid peroxidation (LPx) catalase, superoxide dismutase (SOD), and Glutathione peroxidase (GPx) were carried out by standard methods. Results. TSH was elevated in the nephrotic patients compared to controls, while TT4 and TT3 were significantly lower in the patients than in controls. Lipid Peroxidation and GPx were significantly higher in the nephrotic syndrome patients than in the controls, while SOD and catalase were significantly lower than in patients than in the control subjects. Conclusion. Nephrotic patients can lose significant amounts of thyroid hormones along with protein in urine, which can affect thyroid status, but this is reversible on remission

Effects of Storage Structures and Moisture Contents on Seed Quality Attributes of Quality Protein Maize

The study was aimed to examine the effects of various storage structures and moisture contents on seed quality attributes of quality protein maize seed. The quality protein maize (QPM-1) seed was tested in conventional seed storage containers (Fertilizer sack and earthen pot) and the improved hermetic ones (Metal bin, Super grain bag, and Purdue Improved Crop Storage (PICS) bag) at Seed Science and Technology Division, Khumaltar, Nepal during February, 2015 to January 2016. Ten treatments comprising 5 storage devices in two moisture regimes (11% and 9%) replicated thrice and laid out in Completely Randomized Design (CRD). Data on temperature, relative humidity (RH), germination, electrical conductivity (EC), seed moisture content (MC) were collected bimonthly. The conventional containers were found liable to the external environmental condition whereas the hermetic structures observed with controlled RH level below 40% in all combinations. Electrical conductivity (EC) for seed vigor showed that hermetic containers provide higher seed vigor than the conventional ones. Up to 4 months all treatments were found statistically at par for germination. A significant difference was observed in each treatment after 4 months where PICS bag & Super grain bag showed best germination followed by metal bin while fertilizer bag & earthen-pot showed poorer and poorest germination respectively till one year. Almost all treatments with lower MC showed better results than the treatments with higher MC. A negative correlation (R2=69.7%) was found between EC and Germination. All six figures from 2 to 12 months on MC showed statistically different where hermetic plastic bags were found maintaining MC as initial whereas MC of fertilizer bags and earthen pot was spiked than the basal figure. The finding evidenced that the hermetic containers and low MC are the seed storage approaches for retaining the quality of seed even in an ambient environmental condition for more than a year

Determination of the structure of the recombinant T = 1 capsid of Sesbania mosaic virus

The recombinant coat protein (CP) of Sesbania mosaic virus lacking segments of different lengths from the N-terminus expressed in E. coli was shown to selfassemble into a variety of distinct capsids encapsidating 23S rRNA from the host and CP mRNA in vivo. Particles with 60 copies (T = 1) of protein subunits were observed when protein lacking 65 amino acids from the N-terminus was expressed. This recombinant protein possesses the sequence corresponding to the S-domain of the native, T = 3 icosahedral particles but lacks the β-annulus, the βA strand (residues 67–70) and the arginine-rich ARM motif (residues 28–36). Purified T = 1 particles crystallized in the monoclinic space group P21 with cell parameters of a = 188.4 Å, b = 194.6Å, c = 272.1Å and β=92.6°. The structure of the T = 1 particles was determined by X-ray diffraction at 3.0 Å resolution. As expected, the poly-peptide fold of the subunit closely resembles that of the S-domain of the native virus. The recombinant particles bind calcium ions in a manner indistinguishable from that of the native capsids. The structure reveals the major differences in the quaternary organization responsible for the formation of T = 1 against T = 3 particles

Post-frontline demonstration impact analysis of open sea cage culture among Sidi tribes in Gujarat

Front line demonstrations (FLD) evolved by the Indian Council of Agricultural Research are conducted under the close supervision of scientists of the National Agriculture Research System, where in technologies are demonstrated for the first time by the scientists themselves before being fed in to the main extension system of the state machinery. Post-front line demonstration impact analysis on open sea cage culture of finfishes and lobsters, among Sidi tribes of Gujarat aimed at assessing the socio-personal, socio-psychological and socio-economic and behavioural characteristics of Sidis - a primitive tribal group who are the beneficiaries of the open sea cage culture programme of the Central Marine Fisheries Research Institute (CMFRI) under the Tribal Sub-Plan (TSP) of the Government of India. Using multistage random sampling method, a sample of 135 Sidi tribals were selected from Veraval and Talala taluks in Junagadh District of Gujarat. The group consisted of 45 Sidis practising cage culture, 45 non-practising beneficiaries of the tribal society and 45 Sidis who were non-practising non-beneficiaries of the society. The findings of the study revealed that most of the participant beneficiaries (58.33%) were having high school level of education, compared to non-participant beneficiaries, most of whom were illiterates (55.55%). It could be inferred that, the participant beneficiaries had a higher average monthly income of ` 1,216.25 when compared to non-participant beneficiaries who earned an average monthly income of ` 854.25. Among the participant beneficiaries, 41.67% had medium level of knowledge in cage culture, 50% had medium level of attitude and 75% had medium level of perceived skill in cage culture technologies

Phenotypic profiling of lentil (Lens culinaris Medikus) accessions enabled identification of promising lines for use in breeding for high yield, early flowering and desirable traits

In the face of climate change, developing resilient crops is crucial for global food security in the 21st century to feed a growing population. Lentil (Lens culinaris Medikus) plays a vital role in ensuring global food and nutritional security. Traits like early flowering enable the crop to mature faster, thereby shortening the growing window and reducing yield losses caused by moisture and heat stresses during the reproductive phase. However, issues like limited genetic diversity in this trait remain unaddressed. To address this gap, our study aims to comprehensively assess genetic variability and trait associations in 158 lentil accessions. In the present study, we observed significant variations for days to 50% flowering (67–90 days), days to maturity (109–122 days) and 100 seed weight (1.69–2.68 g) throughout a period of two consecutive years (2020–2021 and 2021–2022). The observed variability in these traits offers a valuable avenue for the improvement of lentil yield through targeted selection and hybridization. Additionally, correlation analysis showed negative correlation between days to 50% flowering and grain yield per plant, while plant height had a significant (P < 0.01) positive correlation with all traits except yield per plant. Furthermore, we identified specific germplasm with exceptional traits that hold significant potential for future breeding programmes. The genotypes EC 223197-A and EC 267696 were identified for early flowering with high yield, and other genotypes that were identified for various traits would serve as breeding material for the introgression of these traits into elite cultivars

A Single Heterochromatin Boundary Element Imposes Position-Independent Antisilencing Activity in Saccharomyces cerevisiae Minichromosomes

Chromatin boundary elements serve as cis-acting regulatory DNA signals required to protect genes from the effects of the neighboring heterochromatin. In the yeast genome, boundary elements act by establishing barriers for heterochromatin spreading and are sufficient to protect a reporter gene from transcriptional silencing when inserted between the silencer and the reporter gene. Here we dissected functional topography of silencers and boundary elements within circular minichromosomes in Saccharomyces cerevisiae. We found that both HML-E and HML-I silencers can efficiently repress the URA3 reporter on a multi-copy yeast minichromosome and we further showed that two distinct heterochromatin boundary elements STAR and TEF2-UASrpg are able to limit the heterochromatin spreading in circular minichromosomes. In surprising contrast to what had been observed in the yeast genome, we found that in minichromosomes the heterochromatin boundary elements inhibit silencing of the reporter gene even when just one boundary element is positioned at the distal end of the URA3 reporter or upstream of the silencer elements. Thus the STAR and TEF2-UASrpg boundary elements inhibit chromatin silencing through an antisilencing activity independently of their position or orientation in S. cerevisiae minichromosomes rather than by creating a position-specific barrier as seen in the genome. We propose that the circular DNA topology facilitates interactions between the boundary and silencing elements in the minichromosomes

E-consultation and the quest for inclusive governance in Nigeria

Inclusive governance through public consultation is fundamental to sustainable development as reiterated in the SDG16. Citizens’ consultation in the policy planning and determination enhances the quality of policy outcomes and help to build public trust in political institutions. Traditional institutions for public consultation are however, often limited thus, policy decisions are in most cases, at variance with public aspirations. The consequence is a growing public cynicism of governmental institutions. To address this democratic decline, governments across the world are now utilizing ICT tools to better consult with citizens in the public policy process. This paper which adopts a mixture of descriptive and analytical research designs engages a systematic literature review for collecting and analysing data. The aim is to investigate the adoption of ICTs as tools for public consultation to enhance inclusive governance in Nigeria. Findings reveal among others that the increase in acceptance and usage of mobile technologies in the face of the challenges of infrastructure, energy instability and low level of ICT literacy among others, provide veritable platform for e-consultation. E-consultation brings to bear the equally important bottom-up approach in policy making by providing additional channel for greater public voice in the policy-making process. E-consultation thus poses to be cardinal to achieving sustainable development goal of just, peaceful and inclusive societies in Nigeria

The Ser82 RAGE variant affects lung function and serum RAGE in smokers and sRAGE production in vitro

Introduction: Genome-Wide Association Studies have identified associations between lung function measures and Chronic Obstructive Pulmonary Disease (COPD) and chromosome region 6p21 containing the gene for the Advanced Glycation End Product Receptor (AGER, encoding RAGE). We aimed to (i) characterise RAGE expression in the lung, (ii) identify AGER transcripts, (iii) ascertain if SNP rs2070600 (Gly82Ser C/T) is associated with lung function and serum sRAGE levels and (iv) identify whether the Gly82Ser variant is functionally important in altering sRAGE levels in an airway epithelial cell model. Methods: Immunohistochemistry was used to identify RAGE protein expression in 26 human tissues and qPCR was used to quantify AGER mRNA in lung cells. Gene expression array data was used to identify AGER expression during lung development in 38 fetal lung samples. RNA-Seq was used to identify AGER transcripts in lung cells. sRAGE levels were assessed in cells and patient serum by ELISA. BEAS2B-R1 cells were transfected to overexpress RAGE protein with either the Gly82 or Ser82 variant and sRAGE levels identified. Results: Immunohistochemical assessment of 6 adult lung samples identified high RAGE expression in the alveoli of healthy adults and individuals with COPD. AGER/RAGE expression increased across developmental stages in human fetal lung at both the mRNA (38 samples) and protein levels (20 samples). Extensive AGER splicing was identified. The rs2070600T (Ser82) allele is associated with higher FEV1, FEV1/FVC and lower serum sRAGE levels in UK smokers. Using an airway epithelium model overexpressing the Gly82 or Ser82 variants we found that HMGB1 activation of the RAGE-Ser82 receptor results in lower sRAGE production. Conclusions: This study provides new information regarding the expression profile and potential role of RAGE in the human lung and shows a functional role of the Gly82Ser variant. These findings advance our understanding of the potential mechanisms underlying COPD particularly for carriers of this AGER polymorphism

Potential immunological consequences of pharmacological suppression of gastric acid production in patients with multiple sclerosis

Corticosteroids are standard treatment for patients with multiple sclerosis experiencing acute relapse. Because dyspeptic pain is a common side effect of this intervention, patients can be given a histamine receptor-2 antagonist, proton pump inhibitor or antacid to prevent or ameliorate this disturbance. Additionally, patients with multiple sclerosis may be taking these medications independent of corticosteroid treatment. Interventions for gastric disturbances can influence the activation state of the immune system, a principal mediator of pathology in multiple sclerosis. Although histamine release promotes inflammation, activation of the histamine receptor-2 can suppress a proinflammatory immune response, and blocking histamine receptor-2 with an antagonist could shift the balance more towards immune stimulation. Studies utilizing an animal model of multiple sclerosis indicate that histamine receptor-2 antagonists potentially augment disease activity in patients with multiple sclerosis. In contrast, proton pump inhibitors appear to favor immune suppression, but have not been studied in models of multiple sclerosis. Antacids, histamine receptor-2 antagonists and proton pump inhibitors also could alter the intestinal microflora, which may indirectly lead to immune stimulation. Additionally, elevated gastric pH can promote the vitamin B12 deficiency that patients with multiple sclerosis are at risk of developing. Here, we review possible roles of gastric acid inhibitors on immunopathogenic mechanisms associated with multiple sclerosis
