Genetic variation in the CLOCK gene is associated with idiopathic recurrent spontaneous abortion.

PLoS ONE, 2018
Physiological studies in animals and human support an important role of circadian system in reproduction. The aim of this study was to investigate the potential association of CLOCK gene polymorphisms with idiopathic recurrent spontaneous abortion (IRSA).

Enrichment of Aerobic and Anaerobic Hydrocarbon-Degrading Bacteria from Multicontaminated Marine Sediment in Mar Piccolo Site (Taranto, Italy)

Microorganisms, 2023
Marine sediments act as a sink for the accumulation of various organic contaminants such as polychlorobiphenyls (PCBs). These contaminants affect the composition and activity of microbial communities, particularly favoring those capable of thriving from ...

Spatial-temporal study of cluster 5 picocyanobacteria and exopolymeric microgels in Lake Maggiore

Advances in Oceanography and Limnology, 2022
In the oligotrophic Lake Maggiore, the majority of picocyanobacteria are phycoerythrin-bearing Synechococcus-type belonging to cluster 5 (Pcy-5). Their distribution was followed in a seven-year study along a depth gradient from the surface down to 350 m

Transparent Exopolymer Particles (TEP), phytoplankton and picocyanobacteria a littoral-to-pelagic depth-gradient in a large subalpine lake

Journal of Limnology, 2021
Transparent Exopolymer Particles (TEP) play an important role in the organic carbon cycle of many aquatic systems but the production and distribution of TEP have been studied mainly in the marine environment, neglecting the large oligotrophic lakes.

IRSA Transmission Optimization via Online Learning

CoRR, 2018
In this work, we propose a new learning framework for optimising transmission strategies when irregular repetition slotted ALOHA (IRSA) MAC protocol is considered. We cast the online optimisation of the MAC protocol design as a multi-arm bandit problem that exploits the IRSA structure in the learning framework. Our learning algorithm quickly learns the

Assessment of the adaptive reserve in children with sarcopenia based on the activity level of regulatory systems

Zdorovʹe Rebenka
Background. Sarcopenia, commonly linked with ­aging, has recently been observed in children, affecting 5–40 % of the pediatric population. Loss of muscle mass in childhood limits physical performance and increases the risk of injuries and metabolic ...

Relationship between central hemodynamic parameters and body composition and the functional state of neuro-autonomic regulation in young men

Zaporožskij Medicinskij Žurnal
The aim of the study is to examine the relationship between central hemodynamic parameters and body composition by considering baseline functional state of neuro-autonomic regulation according to the index of regulatory system activity (IRSA) in young ...

An Overall Perspective for the Study of Emerging Contaminants in Karst Aquifers

Resources, 2022
Karst aquifers are essential drinking water sources, representing about 25% of the total available sources globally. Groundwater ecosystems consist of fissured carbonate rocks commonly covered with canopy collapse sinkholes.

Environmental factors as drivers for macroinvertebrate and diatom diversity in Alpine lakes: New insights from the Stelvio National Park (Italy)

Journal of Limnology, 2019
Information on the biodiversity of high altitude lakes in the Stelvio National Park was scarce and fragmentary, in most cases limited to a few studies on a single biological issue. To fill this gap, a multidisciplinary research program was established in
