Review of Particle Physics
2020
The Review summarizes much of particle physics and cosmology. Using data from previous editions, plus 2,143 new measurements from 709 papers, we list, evaluate, and average measured properties of gauge bosons and the recently discovered Higgs boson, leptons, quarks, mesons, and baryons. We summarize searches for hypothetical particles such as supersymmetric particles, heavy bosons, axions, dark photons, etc. Particle properties and search limits are listed in Summary Tables. We give numerous tables, figures, formulae, and reviews of topics such as Higgs Boson Physics, Supersymmetry, Grand Unified Theories, Neutrino Mixing, Dark Energy, Dark Matter, Cosmology, Particle Detectors, Colliders, …
Short-term impact of biogas digestates on soils microbial communities
2022
International audience; Anaerobic digestion of organic waste is considered a key process to produce renewable energy to meet the growing sustainable energy demand. Digestates can be used in agriculture as soil amendments and improve crop yields. However, their use at large scale in agricultural fields still requires to prove their innocuity on soil biota, especially on microorganisms that play important roles in soil ecosystem. Here, we designed a microcosm experiment to compare the short-term (42-days) effects of four different digestates (derived from cattle manure, energy crop, food residues or slurry with bio-waste) on the soil microbial communities. Each digestate was applied on three …

HPLC Determination of Polyphenols from Calendula officinalis L. Flowers
2017
Abstract Romanian spontaneous flora provides a lot of resources for the determination of different chemical compounds. This study uses flower samples from Calendula officinalis L. extracted through maceration. The chemical compounds determined were: (+)-catechin, caffeic acid, chlorogenic acid, cinnamic acid, ferulic acid, gallic acid, rutin, resveratrol and quercetin. They were analyzed by using an optimized HPLC method. (+)-Catechin, caffeic acid, chlorogenic acid and quercetin could not be identified in the analyzed samples. The greatest amount of phenolic compound found was rutin and the smallest quantity was determined for ferulic acid. The quantified compounds have proven to have bene…
DEFECTS IN DOPAMINERGIC PATHWAY AFFECT CONTRACTILITY OF COLON FROM HYPOXANTHINE-GUANINE PHOSPHORIBOSYLTRANSFERASE (HPRT) KNOCKOUT MICE.
2010
Lesch-Nyhan disease is an X-linked neurobehavioral and metabolic disorder caused by lack of hypoxanthine phosphoribosyltransferase (HPRT), a housekeeping enzyme responsible for recycling purines. The mechanisms underlying the neuropathology are not well understood, but the main neurochemical defect, in central nervous system, is linked to a dysfunction of dopaminergic pathway. In the enteric nervous system the dopaminergic nerves are a subset neurons of regulating gut motility, thus we investigated possible changes in colonic motility of HPRT ¯mice related to the dopaminergic control. We evaluated, in vitro, the mechanical activity of circular muscle strips from wild type and HPRT – mouse c…

Recent improvements in in situ hybridization for the detection of HPV infections in clinical samples
2020
Objective: Human Papilloma Virus (HPV) infection is well-established as a cause of cervical cancer. Importantly, early HPV detection can decrease both the frequency and mortality of HPV-related cancers. In situ hybridization (ISH) is a widely used method for the early detection of HPV. Yet, ISH can be expensive, time-consuming and, in some cases, insufficiently sensitive to detect nucleic acid target at low copy number, which may lead to false-positive or false-negative results. To address these limitations, we recently developed a novel in situ hybridization technology based on proprietary Loop RNA probes (LRPs), which provides enhanced sensitivity, high-specificity and improved cost-effec…
POTENTIAL IMPACT OF A NONAVALENT VACCINE ON HPV RELATED LOW-AND HIGH-GRADE CERVICAL INTRAEPITHELIAL LESIONS
2016
Introduction: Demonstration of the role of persistent infection, with high-risk (HR) human papillomaviruses (HPV) as the causal agent of cervical cancer made the development of first and second generation prophylactic vaccines. Bivalent and quadrivalent HPV vaccines are at the moment available in Europe. In 2014 is licensing a nonavalent HPV vaccine against HPV types: 6/11/16/18/31/33/45/52/58. The aim of our study was to evaluate the potential impact on HPV infection and related low- and high-grade cervical lesions (LSIL, HSIL) of the candidate nonavalent HPV vaccine, compared to the impact of the quadrivalent, in a female population living in Sicily. Materials and Methods: HPV genotypes w…
HYDROCARBONS REMOVAL FROM BILGE WATER BY ADSORPTION ONTO ACTIVATED BIOCHAR FROM POSIDONIA OCEANICA
2019
The normal operations carried out on the boats during navigation generate waste waters such as oily bilge water. The latter is the aqueous mixture of potential pollutants of different origins and types: oily fluids, lubricants and greases, cleaning fluids and other wastes that accumulate in the lower part of the vessel [1,2]. The current legislation provides that they can be discharge directly into the sea if the concentrations of some components are below the expected limits. In particular, with regard to oil / hydrocarbons contamination, the current regulatory limit is 15 mg L-1 of total hydrocarbons. The present work starts from a public/private partnership funded by a grant of the Minis…
