Vertebrates are constantly exposed to pathogens, and the adaptive immunity has most likely evolved to control and clear such infectious agents. CD4+ T cells are the major players in the adaptive immune response to pathogens. Following recognition of pathogen-derived antigens naïve CD4+ T cells differentiate into effectors which then control pathogen replication either directly by killing pathogen-infected cells or by assisting with generation of cytotoxic T lymphocytes (CTLs) or pathogen-specific antibodies. Pathogen-specific effector CD4+ T cells are highly heterogeneous in terms of cytokines they produce. Three major subtypes of effector CD4+ T cells have been identified: T-helper 1 (Th1) cells …

An Overview On The Marine Neurotoxin, Saxitoxin: Genetics, Molecular Targets, Methods Of Detection And Ecological Functions, K. Cusick, Gary S. Sayler

Marine neurotoxins are natural products produced by phytoplankton and select species of invertebrates and fish. These compounds interact with voltage-gated sodium, potassium and calcium channels and modulate the flux of these ions into various cell types. This review provides a summary of marine neurotoxins, including their structures, molecular targets and pharmacologies. Saxitoxin and its derivatives, collectively referred to as paralytic shellfish toxins (PSTs), are unique among neurotoxins in that they are found in both marine and freshwater environments by organisms inhabiting two kingdoms of life. Prokaryotic cyanobacteria are responsible for PST production in freshwater systems, while eukaryotic dinoflagellates are the …

Biofield And Fungicide Seed Treatment Influences On Soybean Productivity,Seed Quality And Weed Community, Mahendra Kumar Trivedi
Biofield And Fungicide Seed Treatment Influences On Soybean Productivity,Seed Quality And Weed Community, Mahendra Kumar Trivedi
Mahendra Kumar Trivedi
Soybean production in Iowa USA is among the most productive for raínfed regions in the world. Despite generally having excellent soils, growing season temperatures and rainfall, soybean yields are decreased by weed interference and inadequate available soil water at key stages of crop development. A field study was conducted at two locations in lowa in 2012 to determine if seed-applied fungicide or biofield treatments influenced weed community, soil volumetric water concentration and soybean yield and quality. Application of biofield treatment resulted in lower density of tall waterhemp density, greater soybean stand density at R8 stage and greater seed pod-1 compared …
Impact Of Biofield Treatment On Ginseng And Organic Blueberry Yield, Mahendra Kumar Trivedi
Impact Of Biofield Treatment On Ginseng And Organic Blueberry Yield, Mahendra Kumar Trivedi
Mahendra Kumar Trivedi
This study tested the Null Hypothesis forthe effect of BioField Energy applied to two separate crops under typical growing conditions, namelyginseng and organic blueberry in commercial plantings in Wisconsin and California, respectively. Following treatment to replicated plots in standard experimental design, data were collected at harvest for yield quantity and quality. Ginseng plants treated both pre-harvest and a combination of pre- and post-harvest showed market grade increases of 33.3% and 40.0%, respectively. Point of sale gross return for this crop is dependent upon tuber quality, and from these data the economics of these treatments were calculated. Based on stand adjusted …

Recent advances in bacteriology and medical science affirm that the commensal relationship between surface microbial flora and the human host is intricate and important. Legal theory has thus far lagged behind the impact of the medical discoveries.

The aim of this work was to optimize the biodegradation of polyvinyl alcohol (PVA) containing actual textile wastewater for a sustainable treatment solution. The isolated microbial consortia of effective PVA degrader namely Candida Sp. and Pseudomonas Sp., which were responsible for symbiotic degradation of chemical oxidation demand (COD) and PVA from desizing wastewater. In the process optimization, the maximum aeration was essential to achieve a high degradation rate, where as stirring enhances further degradation and foam control. Batch experiments concluded with the need of 16 lpm/l and 150 rpm of air and stirring speed respectively for high rate of COD …

This study reports a user-friendly technique in the preparation of fungal inoculum intended for solid-state fermentation (SSF) – Cellophane Film Culture (CFC) technique. This technique uses cellophane film-overlaid agar plates to facilitate the separation of fungal biomass. The findings showed that inoculum of P. sajor-caju produced is viable, and it was confirmed by the presence of laccase enzyme activity in SSF of rice husk. The correlation between fungal dry and wet weights (r2 = 0.9329) provides an accurate estimation of fungal dry weight from its wet weight during inoculum preparation. Besides, this technique does not require a strict sterile handling …

Half of the microbial cells in the Earth’s oceans are found in sediments. Many of these cells are members of the Archaea, singlecelled prokaryotes in a domain of life separate from Bacteria and Eukaryota. However, most of these archaea lack cultured representatives, leaving their physiologies and placement on the tree of life uncertain. Here we show that the uncultured miscellaneous crenarchaeotal group (MCG) and marine benthic group-D (MBG-D) are among the most numerous archaea in the marine sub-sea floor. Single-cell genomic sequencing of one cell of MCG and three cells of MBG-D indicated that they form new branches basal to …
