Pollinators: Their Relevance in Conservation and Sustainable Agro-Ecosystem

Survival and reproduction of several wild plants and crops is mostly by insects pollinator, their recognition and importance have been increased in this climatic changing scenario, which affects the various aspects of their life cycle. According to an estimate, approximately 30,000 species of bees are known in entomology, and about 190 species of bees have been reported to be associated with pollination. There can be an established link between seed production and pollinator diversity, for the plants with a generalist pollination system. The increasing of human habitation affects insect pollinators in various ways, i.e. of habitat destruction, results in low availability of food sources, nesting, oviposition, resting, and mating sites. Pollinator availability restraints the geographical distribution of plant species, i.e. to develop an ecological niche of certain plant species. Failure of pollinator- plant interaction mutualism results in lower seed production and sometimes extirpation of plant population has been recorded. The declining pollinators’ population strengthens existing plant-pollinator interaction or allows new pant pollinator interaction to form. Maintaining the commercial and wild pollinator populations and preventing future shortages of pollination services, therefore, is extremely significant

FOOD ALLERGY: AN OVERVIEW

oai:ojs.pkp.sfu.ca:article/1The immune system protects our body against pathogens and other foreign substances by producing a kind of glycoprotein known as immunoglobulin or antibodies from plasma cells or B-cells. Surveys show that about one-third of all adults believe they have food allergies. About 4-8% percent of young children are diagnosed with food allergies, most of which are evident in the first years of life and are often outgrown. A food allergy is any adverse reaction to an otherwise harmless food or food component that involves the body’s immune system. In others words, a food allergy is an immune system response to a food that the body mistakenly believes is harmful. Components of a food that trigger the immune system are called food allergens. Cows’ milk allergy appears to be among the more prevalent food allergies in infants. Eggs and peanuts are also common allergenic foods for infants, along with soybeans, tree nuts, fish, and wheat. Seafood allergies, especially to crustaceans (shrimp, crab, lobster) are also rather common among adults. The present review provides brief information about food allergy and allergic reactions, their types, symptoms and approaches for reduction

Synthesis, antimalarial activity evaluation and molecular docking studies of some novel dispiro-1,2,4,5-tetraoxanes

Seven novel dispiro-1,2,4,5-tetraoxane derivatives were synthesized and characterized by a number of analytical and spectroscopic techniques. The molecules were subsequently screened for in vitro antimalarial activity against chloroquine resistant strain of Plasmodium falciparum (RKL-9). At antimalarial activity screening, two compounds, namely 5d (MIC = 15.6 µg/mL or 64.5 µM) and 5f (MIC = 15.6 µg/mL or 54.6 µM) were found to be about 1.5 times more potent against chloroquine resistant strain-RKL-9 compared to chloroquine (MIC = 25.0 µg/mL or 78.3 µM). Molecular docking studies of potent ligands were also performed in cysteine protease binding pocket residues of falcipain-2 as a target protein

Atypically Large Arteriovenous Malformation: A Surgical Challenge

Arteriovenous malformation (AVM) is an abnormal connection between arteries and veins, bypassing the capillary system. The majority of AVMs involve the extremities, head and neck, and lungs. We report a case of a 20-year-old female with a large, high flow AVM at unusual location. The perforators of this malformation were originating directly from lumbar arteries, revealed by computed tomography angiography. In the absence of facilities of embolizing feeder vessels, such large AVM gave us a great surgical challenge in terms of dissection, raising the mass, ligating perforators, and avoiding skin loss

PHARMACEUTICAL APPLICATIONS OF RS: AN OVERVIEW

Introduction: In recent years, extensive research has been done worldwide for crop waste management so that its various components can be used effectively in various industries. Numerous on- and off-field strategies exist for dealing with RS. The health and environmental concerns render in-field management techniques such as burning, mulching, inclusion, etc., impractical. The second largest volume of agricultural waste is produced when it is burned, which poses health problems due to air pollution and harms organic matter by causing significant nutrient losses. Aim: Since Rice Straw (RS) contains a lot of cellulose, researchers are interested in exploring its possible use in the pharmaceutical sector. The chemical nature of RS and the many therapeutic uses of RS-derived biomaterial are the main topics of this review. Pharmaceutical uses include using RS-derived biomaterial as a drug carrier, excipient, packaging material, cosmetic ingredient, and developing other products with added value

Deciphering Pearl Millet Grain Yield under Water Stress using Genotypic, Phenotypic Correlation and Path Coefficient Analysis

Yield is a polygenic character, usually depends on its various contributing traits like days to 50% flowering, plant height, and panicle length as well as panicle girth. A study was conducted during kharif 2018 to evaluate the relationship between grain yield and its components in pearl millet using correlation and path analysis studies. In the current study, significant genotypic and phenotypic correlations were found among five yield contributing traits in eighteen pearl millet hybrids. The traits including days to 50% flowering, plant height, and panicle length were found to have positive correlation with grain yield per plant that implied the importance of those traits in selection of high yielding hybrids. Grain yield per plant was used as a dependent character in path-coefficient analysis at the genotypic level. Plant height and panicle length were the independent variables (cm). The highest positive and direct effect was found for days to 50 percent flowering (0.9946) followed by panicle diameter (cm) (0.5726). Pearl millet having deep root system are often found to survive even in various stressful conditions including water stress. These characteristics have made it popular in dry and semi-arid regions around the world; nevertheless, compared to other major cereals, less work has been put into the study of climate-resilient characteristics of pearl millet. We have revealed here some basic ideas of correlation between the grain yield of pearl millet with its yield contributing constituents under drought condition
