Rubella, or German measles, is a vaccine-preventable disease. Rubella infection is usually mild; however, infection in pregnancy is associated with severe outcomes for the baby, including pregnancy loss or a combination of developmental defects called congenital rubella syndrome. Within the last ten-year period, two cases of congenital rubella syndrome in Saskatchewan were reported to the provincial ministry and the Public Health Agency of Canada of the newborns of mothers who had recently arrived from Sub-Saharan Africa.

Background: Adenoid is a mass of lymphoid tissue seen in the posterior nasopharyngeal wall, generally seen in the pediatric age group, and it disappears as age advances till puberty. Patients with recurrent allergic rhinitis, otitis media, or persistent nasopharyngeal obstruction is associated with adenoid hypertrophy can be considered for adenoidectomy.

Objective: To evaluate the potential role of Individualised Homeopathic medicine in managing allergic rhinitis and troublesome symptoms of upper respiratory tract in case of Enlarged adenoid.

Objective: Cervical cancer, a prevalent and deadly disease among women, comes second only to breast cancer, with over 700 daily deaths. The Pap smear test is a widely utilized screening method for detecting cervical cancer in its early stages. However, this manual screening process is prone to a high rate of false-positive outcomes because of human errors.

Biological interpretation of metabolomic datasets often ends at a pathway analysis step to find the over-represented metabolic pathways in the list of statistically significant metabolites. However, definitions of biochemical pathways and metabolite coverage vary among different curated databases, leading to missed interpretations. For the lists of genes, transcripts and proteins, Gene Ontology (GO) terms over-presentation analysis has become a standardized approach for biological interpretation.

Inter-chemical correlations in metabolomics and exposomics datasets provide valuable information for studying relationships among chemicals reported for human specimens. With an increase in the number of compounds for these datasets, a network graph analysis and visualization of the correlation structure is difficult to interpret. We have developed the Chemical Correlation Database (CCDB), as a systematic catalogue of inter-chemical correlation in publicly available metabolomics and exposomics studies.

Heavy metals' amassment in the soil environment is a threat to crop and agricultural sustainability and consequentially the global food security. For achieving enhancement of crop productivity in parallel to reducing chromium (Cr) load onto food chain demands continuous investigation and efforts to develop cost-effective strategies for maximizing crop yield and quality. In this context, we investigated the amelioration of Cr(VI) toxicity through β-pinene in experimental dome simulating natural field conditions.

Soil alkalinity caused by salts, such as sodium bicarbonate (NaHCO), and the frequently associated waterlogging problems are pervasive in agriculture and have a deleterious impact on crop production. However, various plant growth regulators, including brassinosteroids, are considered to be important against different abiotic stresses experienced by plants due to drought, salinity, and heavy metal stress. We investigated the putative role of 24-epibrassinolide (EBL), an active brassinosteroid, on red rice plants experiencing alkaline stress.

We examined the possible role of monoterpene β-pinene in providing protection against Cr(VI) toxicity in maize (Zea mays). Treatment with β-pinene (10 μM) significantly alleviated Cr(VI) accumulation and recuperated Cr(VI) caused decline in root and coleoptile growth in maize. β-Pinene addition caused a decline in Cr(VI)-induced accumulation of superoxide anion, hydroxyl ion, hydrogen peroxide and confirmed by in-situ detection of ROS using histochemical localization.

Nitric Oxide (NO) is a bioactive signaling molecule that mediates a variety of biotic and abiotic stresses. The present study investigated the role of NO (as SNP [sodium nitroprusside]) in ameliorating lead (Pb)-toxicity in Triticum aestivum (wheat) roots. Pb (50 and 250 μM) alone and in combination with SNP (100 μM) was given to hydroponically grown wheat roots for a period of 0-8 h.

The present study examined the toxic effects of Cr(VI; 100, 250 and 500 μM) in maize seedlings by investigating the changes in carbohydrate metabolism after 48, 96, and 144 h of exposure. Cr-stress results in severe alterations in the contents of carbohydrates and reducing sugars and the activities of carbohydrate metabolizing enzymes, amylases, phosphatases and phosphorylases, and invertases in maize seedlings. Under Cr stress, the contents of carbohydrates and reducing sugars declined in roots, whereas an increase was noticed in leaves.

Indian religions and cultures are diverse and have always influenced the way people live in this part of the world. Religion has been a very dominant influence in marriage, choice of marital partner and cohabitation. The present paper looks at various religions in India and their influence on sexual attitudes and the institution of marriage.

The present study investigated the effect of Arsenic (As; 5, 10, 50 μM) on protein and sugar metabolism vis-à-vis oxidative damage during early germination process and radicle emergence (at 12, 24 and 48 h stage) in Phaseolus aureus. As-exposure (50 μM) significantly enhanced protein content (by 40-60%), whereas carbohydrate content declined (by 31-44%) over that in the control. It was associated with a decline in the activities of proteases (47-53%), and increase in the activities of α- and β-amylases, starch phosphorylases, and acid invertases by 3.
