Handling Practices During Distribution Of Kinnow-Mandarins (Citrus Nobilis X Citrus Deliciosa) Used For Preparation Of Fresh-Squeezed Juices And Their Effects On Microbiological Safety, M. Ghosh, A. Ganguli, M. Kumar Apr 2025

Handling Practices During Distribution Of Kinnow-Mandarins (Citrus Nobilis X Citrus Deliciosa) Used For Preparation Of Fresh-Squeezed Juices And Their Effects On Microbiological Safety, M. Ghosh, A. Ganguli, M. Kumar

Journal of Agricultural and Marine Sciences

The objective of this study was to assess the microbiological safety of Kinnow-mandarins (Citrus nobilis X Citrus deliciosa) used for preparation of fresh squeezed juices by street vendors. One hundred and fifty Kinnow mandarin samples were collected from different points in the distribution chain from the same lot, washed and aliquots of the wash samples were analyzed for total aerobes, Staphylococcus, total and fecal coliforms, Salmonella and Shigella. Although, there was no notable increase in the total aerobic, total or fecal coliform counts, total staphylococcal counts increased significantly (P<0.05) during distribution to street vendors; seventy-two samples from the street vendors showed the presence of coagulase positive Staphylococcus aureus, twenty-three of these produced enterotoxins B and C. Salmonella and Shigella were not detected in any of the samples. Sources of high numbers of enterotoxigenic S. aureus were traced to unhygienic manual handling by middle level buyers and by street vendors. The results of our study demonstrate the poor microbiological quality of Kinnow-mandarins, the possible entry points of contaminants in the distribution chain of these fruits and unhygienic vending practices. Appropriate intervention measures are needed to ensure safe fresh squeezed juices for consumers.

Livestock Environment Prospects For The 90'S, W. W. Thatcher Apr 2025

Livestock Environment Prospects For The 90'S, W. W. Thatcher

Journal of Agricultural and Marine Sciences

When projecting livestock environmental prospects for the 1990's. it is critical to recognize the multidimensional nature of managing livestock species under hot environments. This paper identifies potential critical physiological windows during the life cycle of the animal that are sensitive to heat stress and responsive to environmental modification. Ovarian follicular development appears to be sensitive to heat stress leading to reductions in intensity of oestrus and subsequent fertility. Periods of follicular development that are sensitive to heat stress have not been defined. With current improved systems to alter the microenvironment of animals. the period of embryonic sensitivity to heat stress …

Metabolite Analysis To Understand Factors Limiting Microbial Fermentation At High Substrate Concentrations, Bishal D. Sharma Apr 2025

Metabolite Analysis To Understand Factors Limiting Microbial Fermentation At High Substrate Concentrations, Bishal D. Sharma

Dartmouth College Ph.D Dissertations

Clostridium thermocellum, a thermophilic anaerobic bacterium, holds promise as a biocatalyst for conversion of lignocellulosic biomass into biofuels. This microbe has been subjected to various metabolic engineering strategies, including the deletion of genes encoding secondary fermentation products such as H₂, formate, acetate, and lactate, as well as the expression of heterologous genes to redirect carbon flux toward ethanol production. Despite these efforts, achieving economically viable ethanol titers remains a challenge. We hypothesized that studying how intracellular metabolite concentrations change as fermentation stops could reveal metabolic bottlenecks or regulatory mechanisms limiting ethanol production at high titers. However, metabolomics studies at …

Abstract Title: What Is Chaga? Unique Biochemistry Of The Sterile Conk., Anna Kreynes Apr 2025

Abstract Title: What Is Chaga? Unique Biochemistry Of The Sterile Conk., Anna Kreynes

Oxford ICSB

Fungal based supplements or functional mushrooms are growing in popularity worldwide. Among them, Chaga is attracting increasing attention for its broad immune-modulatory and anti-inflammatory properties. Chaga is unique among “mushroom” supplements as it is technically neither a mushroom (fruiting body), nor a sclerotia, as some researchers assert, but rather a sterile conk or canker that forms on trees, infected and colonized by mycelia of the pathogenic fungus Inonotus obliquus. Commonly associated with birch (Betula spp.), I. obliquus also parasitizes other hardwood species such as alder (Alnus), beech (Fagus), and ash (Fraxinus), found in boreal forests of northern Europe, Asia and …

Seed Yield, Fodder Yield And Persistence In White Clover Cvs Of Different Origins. Results Of Trials Conducted At Lodi (Irrigated Po Valley), R Paoletti, C Locattello

IGC Proceedings (1977-2023)

White clover is the most important pasture legume in many EEC countries (white clover-ryegrass pasture system) and a good component of permanent and rotated polyphytic meadows in North Italy (irrigated Po Valley where the Ladino subspecies developed through self selection). The main char­acteristics of the species are N2 fixation and high nutritional value (quality). Therefore, white clover seed usage in the EEC is expected to still be important in the next decades. A number of performing varieties have recently been developed by EEC Research Institutes. An assessment of their seed production potential is necessary in view of self-sufficiency and consequent …

Vestibular Neurons Link Motion Sickness, Behavioural Thermoregulation And Metabolic Balance In Mice, Longlong Tu, Xing Fang, Yongjie Yang, Meng Yu, Hailan Liu, Hesong Liu, Na Yin, Jonathan C Bean, Kristine M Conde, Mengjie Wang, Yongxiang Li, Olivia Z Ginnard, Qingzhuo Liu, Yuhan Shi, Junying Han, Yi Zhu, Makoto Fukuda, Qingchun Tong, Benjamin Arenkiel, Mingshan Xue, Yang He, Chunmei Wang, Yong Xu

Children’s Nutrition Research Center Staff Publications

Motion sickness is associated with thermoregulation and metabolic control, but the underlying neural circuitry remains largely unknown. Here we show that neurons in the medial vestibular nuclei parvocellular part (MVePC) mediate the hypothermic responses induced by motion. Reactivation of motion-sensitive MVePC neurons recapitulates motion sickness in mice. We show that motion-activated neurons in the MVePC are glutamatergic (MVePCGlu), and that optogenetic stimulation of MVePCGlu neurons mimics motion-induced hypothermia by signalling to the lateral parabrachial nucleus (LPBN). Acute inhibition of MVePC-LPBN circuitry abrogates motion-induced hypothermia. Finally, we show that chronic inhibition of MVePCGlu neurons prevents diet-induced obesity and improves glucose homeostasis …
