Efficacy of Grignard Pure to Inactivate Airborne Phage MS2, a Common SARS-CoV-2 Surrogate.

Grignard Pure (GP) is a unique and proprietary blend of triethylene glycol (TEG) and inert ingredients designed for continuous antimicrobial treatment of air. TEG has been designated as a ″Safer Chemical" by the US EPA. GP has already received approval from the US EPA under its Section 18 Public Health Emergency Exemption program for use in seven states.

Controlled filamentation instability as a scalable fabrication approach to flexible metamaterials.

Long and flexible arrays of nanowires find impactful applications in sensing, photonics, and energy harvesting. Conventional manufacturing relies largely on lithographic methods limited in wafer size, rigidity, and machine write time. Here, we report a scalable process to generate encapsulated flexible nanowire arrays with high aspect ratios and excellent tunable size and periodicity.

Course and predictors of physical aggressive behaviour after discharge from a psychiatric inpatient unit: 1 year follow-up.

The present study analyzes course and predictors of physically aggressive behaviour over a 1-year follow up in a sample of patients discharged from a psychiatric inpatient unit. One hundred and eighty-six patients discharged from a locked short-term Psychiatric Inpatient Unit at the Bologna University Hospital. After discharge, two data collection contacts at 1 month and at 1 year were scheduled.

Quantitative measurement of airborne cockroach allergen in New York City apartments.

Unlabelled: We designed and tested a sampling and analysis system for quantitative measurement of airborne cockroach allergen with sufficient sensitivity for residential exposure assessment. Integrated 1-week airborne particle samples were collected at 10-15 LPM in 19 New York City apartments in which an asthmatic child who was allergic to cockroach allergen resided. Four simultaneous air samples were collected in each home: at heights of 0.

Predictors of violent behavior among acute psychiatric patients: clinical study.

Aim: Violence risk prediction is a priority issue for clinicians working with mentally disordered offenders. The aim of the present study was to determine violence risk factors in acute psychiatric inpatients.

Methods: The study was conducted in a locked, short-term psychiatric inpatient unit and involved 374 patients consecutively admitted in a 1-year period.

Hepatobiliary phospholipid transporter ABCB4, MDR3 gene variants in a large cohort of Italian women with intrahepatic cholestasis of pregnancy.

Background: Intrahepatic cholestasis of pregnancy is a multifactorial disorder of pregnancy associated with a genetic background.

Aim: To evaluate the genetic contribution of ABCB4, MDR3 gene in the development of intrahepatic cholestasis of pregnancy in a large cohort of Italian subjects.

Methods: This study represents an extension of a previous multicentre-prospective study including three Italian referral centres.

Effects of alcohol withdrawal on blood pressure in hypertensive heavy drinkers.

Background: Epidemiological investigations have demonstrated a close association between heavy alcohol consumption and hypertension. The mechanisms of this association, however, remain elusive. We studied the effects of alcohol withdrawal on blood pressure, hormonal parameters, and circulating markers of endothelial activity.

Intrahepatic cholestasis of pregnancy: three novel MDR3 gene mutations.

Background: The aetiology of intrahepatic cholestasis of pregnancy is unknown, but more than 10 different MDR3 gene mutations have recently been identified.

Aim: To evaluate the genetic contribution of the MDR3 gene in the pathogenesis of intrahepatic cholestasis of pregnancy in Italian subjects.

Methods: We performed a multicentre prospective case-control study, enrolling 80 women with intrahepatic cholestasis of pregnancy at the third trimester of pregnancy and 80 pregnant women without intrahepatic cholestasis of pregnancy.

Alcohol-induced endothelial changes are associated with oxidative stress and are rapidly reversed after withdrawal.

Background: Although heavy alcohol drinkers are at an increased risk of developing cardiovascular events, moderate alcohol intake is associated with reduced incidence of cardiovascular death. This paradox might reflect a dose-related effect of different alcohol intakes on endothelial function and this, in turn, might depend on changes in oxidative stress.

Methods: We tested the effects of alcohol withdrawal in heavy alcohol consumers and compared the plasma levels of endothelin-1, nitric oxide, plasminogen activator inhibitor-1, von Willebrand factor, malondialdehyde, and intracellular glutathione with those of alcoholics that did not modify their alcohol intake and teetotalers.

Plasma adiponectin is decreased in nonalcoholic fatty liver disease.

Objectives: Nonalcoholic fatty liver disease (NAFLD) is a major cause of liver-related morbidity and is frequently associated with obesity and metabolic syndrome. The recently discovered hormone adiponectin is produced by adipose tissue, and low plasma adiponectin is considered a key factor in the development of the insulin resistance underlying metabolic syndrome. Animal studies suggest that adiponectin may protect against non-alcoholic steatohepatitis, but direct evidence in humans is lacking.

Baseline indoor air quality measurements collected from 136 metropolitan New York region commercial office buildings between 1997-1999.

Between January 1997 and December 1999, 648 surveys were performed in 136 commercial office buildings in the metropolitan New York region as part of an ongoing proactive indoor environmental quality (IEQ) program. Sampling was performed on a spot basis in "nonproblem" buildings, during normal business hours, either quarterly or semiannually. Carbon dioxide (CO2), carbon monoxide (CO), and total volatile organic compounds (TVOCs) were among the various physical and gaseous parameters sampled for.

Visual hallucinations in the 19th century: research in a medical archive.

The authors have gathered and analyzed the visual hallucinations described in the mid- to late-19th century from archived medical records of the former psychiatric hospital "Osservanza" in Imola, northern Italy. Though the investigation was not intended as a statistical survey, the principal aim being to classify the hallucinations according to their outward characteristics, the authors have tried to locate the possible sources of these phenomena in folklore and religious iconography.

Ambient air and its potential effects on conception in vitro.

Incidences of chemical air contamination (CAC) are common in assisted reproductive technology, but not reported in peer review format. Justified fear of car and industrial emissions clearly exists among reproductive specialists, but standards for air contents and gaseous emission limits have not been reported. Here, we describe air sampling methods and assay systems which can be applied to any laboratory or laboratory item.

Acute polyhydramnios associated with chorioangioma. A case report.

A case of acute polyhydramnios occurred at 26 weeks' gestation. Prenatal sonography demonstrated a placental chorioangioma. Acute polyhydramnios is clinically distinct from nonacute polyhydramnios and carries a high perinatal mortality rate.

Impending rupture of nonaneurysmal bacterial aortitis: CT diagnosis.

The CT appearance of mycotic abdominal aortic aneurysms leading to eventual rupture has been well described. On the other hand, ruptured nonaneurysmal bacterial aortitis has not been demonstrated in the CT literature. We present two cases with subsequent rupture documented on CT.
