Food Chem Toxicol 2021 Apr 9:112179. Epub 2021 Apr 9.

Sorbonne Paris North University, Inserm, Inrae, Cnam, Nutritional Epidemiology Research Team (EREN), Epidemiology and Statistics Research Centre, University of Paris (CRESS), Bobigny, France.

Purpose: To examine dietary exposure to 25 pesticide residues in several diet groups including omnivores, pesco-vegetarians, vegetarians and vegans while accounting for the farming system (organic or conventional) of plant-based foods consumed.

Methods: Organic and conventional consumption data in combination with data on pesticide residues in plant-based foods were used to derive estimated dietary exposure to pesticide residues. Pesticide residue exposure was estimated based on observed data, and using two scenarios simulated for 100%-conventional and 100%-organic diets in 33,018 omnivores, 555 pesco-vegetarians, 501 vegetarians and 368 vegans from the NutriNet-Santé study.

Body mass index trajectories among people with obesity and association with mortality: Evidence from a large Israeli database.

Obes Sci Pract 2021 Apr 23;7(2):148-158. Epub 2020 Dec 23.

Clalit Research Institute Clalit Health Services Ramat Gan Israel.

Objective: Previous studies using longitudinal weight data to characterize obesity are based on populations of limited size and mostly include individuals of all body mass index (BMI) levels, without focusing on weight changes among people with obesity. This study aimed to identify BMI trajectories over 5 years in a large population with obesity, and to determine the trajectories' association with mortality.

Methods: For inclusion, individuals aged 30-74 years at index date (1 January 2013) with continuous membership in Clalit Health Services from 2008 to 2012 were required to have ≥1 BMI measurement per year in ≥3 calendar years during this period, of which at least one was ≥30 kg/m. Read More

Can current farmland landscapes feed declining steppe birds? Evaluating arthropod abundance for the endangered little bustard () in cereal farmland during the chick-rearing period: Variations between habitats and localities.

Ecol Evol 2021 Apr 2;11(7):3219-3238. Epub 2021 Mar 2.

Terrestrial Ecology Group (TEG) Department of Ecology, Research Center on Biodiversity and Global Change Autónoma University of Madrid Madrid Spain.

Agriculture intensification threatens farmland bird populations because, among other reasons, it reduces the availability of food resources required to rear their offspring. In our study, we sampled and analyzed total arthropod abundance, biomass and richness, and orthopteran and coleopteran abundance and biomass in different agricultural habitats (alfalfa fields, stubble fields, grazed fields, and field margins) across 4 study localities with different levels of agriculture abandonment-intensification, comparing between areas used and not used by one of the most threatened farmland birds in Europe, the little bustard (), during the chick-rearing season. Field margins were the taxonomically richest habitat, while alfalfa fields presented significantly higher total arthropod abundance and biomass than other habitats. Read More

Acta Neurochir Suppl 2021 ;131:103-107

National Medical Research Center for Children's Health, Moscow, Russia.

Brain biomarkers (protein S100b and neuron-specific enolase (NSE)), antibodies (aAb) to the NR2 subunit of N-methyl-D-aspartate (NR2(NMDA)) and to the GluR1 subunit of the α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (GluR1(AMPA)) subtype of glutamate receptors (GluR), NR2 and AMPA peptides, nitrogen oxides (NOx; "nitrites and nitrates"), and 3-nitrotyrosine (NT) were measured in blood from 159 children after mild traumatic brain injury (mTBI), moderate traumatic brain injury (mdTBI), or severe traumatic brain injury (sTBI) within 1-2 days and at intervals during the first 15 days after brain trauma. S100b and NSE levels on the first day were not a strict criterion for injury outcomes. Children with mTBI had the most significant elevations in antibodies to NR2(NMDA) and AMPA peptides, a slight increase in NOx, and, in 25% of cases, appearance of NT in the blood right after TBI.

Int Immunopharmacol 2021 Mar 27;96:107615. Epub 2021 Mar 27.

Biomedical Informatics Research Lab, School of Basic Medicine and Clinical Pharmacy, China Pharmaceutical University, Nanjing 211198, China; Big Data Research Institute, China Pharmaceutical University, Nanjing 211198, China. Electronic address:

Although previous studies have shown that the host immune response is crucial in determining clinical outcomes in COVID-19 patients, the association between host immune signatures and COVID-19 patient outcomes remains unclear. Based on the enrichment levels of 11 immune signatures (eight immune-inciting and three immune-inhibiting signatures) in leukocytes of 100 COVID-19 patients, we identified three COVID-19 subtypes: Im-C1, Im-C2, and Im-C3, by clustering analysis. Im-C1 had the lowest immune-inciting signatures and high immune-inhibiting signatures. Read More

Estrogen receptor 2 mediates intraspecific aggressive behaviors of the female in the estrous cycle.

J Integr Neurosci 2021 Mar;20(1):77-85

College of Life Sciences, Qufu Normal University, Qufu, 273165 Shandong, P. R. China.

The social behavior mechanisms have not been thoroughly reported in the solitary female striped dwarf hamster (). In this study, the handling bag test and neutral arena measurements were used to detect the changes of aggression in the face of rivals of different genders of wild striped dwarf hamsters. We found that female hamsters had the highest aggressive performance in proestrus, followed by estrus, and the lowest in metestrus and the dioestrus, and the increased aggression during the proestrus or estrus period was low-intensity aggression such as intimidation, shock, boxing and counterattack, or even ritualized non-harmful behaviors to drive away opponents.

Vet Radiol Ultrasound 2021 Apr 8. Epub 2021 Apr 8.

Department of Veterinary Medical Science, Alma Mater Studiorum, University of Bologna, Ozzano Emilia, Italy.

Computed tomography (CT) is increasingly available to evaluate dogs with suspected adrenal disease, however, published studies describing the reproducibility of CT methods for quantifying adrenal gland (AG) measurements are lacking. This prospective, pilot, observer agreement study aimed to evaluate reproducibility and repeatability of two different methods of measurement of AGs on CT to establish a usable technique and define standard reference ranges. Multiplanar reformatted (MPR) CT images of both AGs of six large breed dogs were obtained with the MPR axis parallel to the spine and parallel to the long axis of the AG. Read More
