Identification and Characterization of , , and Species Present in Floricultural Crops from Long Island, New York.

Several , , and species cause Pythium diseases in greenhouse floricultural crops, resulting in significant seasonal losses. Four hundred and eighteen , , and isolates from flowering crops, growing media, or bench and floor debris were collected from Long Island greenhouses or clinic samples between 2002 and 2013. Isolates were identified to species based on morphology and internal transcribed spacer barcoding.

SARS-CoV-2 Spike and Nucleocapsid Antibody Response in Vaccinated Croatian Healthcare Workers and Infected Hospitalized Patients: A Single Center Cohort Study.

Studies assessing the dynamics and duration of antibody responses following SARS-CoV-2 infection or vaccination are an invaluable tool for vaccination schedule planning, assessment of risk groups and management of pandemics. In this study, we developed and employed ELISA assays to analyze the humoral responses to Nucleocapsid and Spike proteins in vaccinated health-care workers (HCW) and critically ill COVID-19 patients. Sera of more than 1000 HCWs and critically ill patients from the Clinical Hospital Center Rijeka were tested across a one-year period, encompassing the spread of major SARS-CoV-2 variants of concern (VOCs).

A reduction of central peptidergic responses in the spontaneously hypertensive rat.

The effect of intraventricular perfusion with hypertonic saline (HS) or angiotensin II (ANG II) on cerebrospinal fluid (CSF) vasopressin (AVP), blood pressure and heart rate was determined in spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats. There was a marked reduction in the central peptidergic response in the SHR. Pretreatment with the AVP (V1) antagonist abolished the pressor response to intraventricular HS in the WKY rats, but not in the SHR.

Involvement of central vasopressin receptors in the control of blood pressure.

Intraventricular perfusion with a hypertonic sodium chloride solution elicits increases in cerebrospinal fluid vasopressin and blood pressure and a decrease in heart rate. The central peptide response was greatly reduced in the hypertensive rat. Central pretreatment with the vasopressin (V1) antagonist completely abolished the pressor response to hypertonic sodium chloride in the normotensive animal.

Osmotic mechanisms regulating cerebrospinal fluid vasopressin and oxytocin in the conscious rat.

The effect of intraventricular and intravenous (i.v.) hypertonic saline on plasma and perfusate arginine vasopressin (AVP) and oxytocin (OT) levels was determined.

Toxicology of organic drinking water contaminants: trichloromethane, bromodichloromethane, dibromochloromethane and tribromomethane.

This study evaluated the subchronic toxicity of selected halomethanes which are drinking water contaminants. The compounds studied were trichloromethane, bromodichloromethane, dibromochloromethane and tribromomethane. Subchronic 14-day gavage studies were performed with the use of doses encompassing one-tenth the LD50 for the compounds.

Toxicology of chloral hydrate in the mouse.

Chloral hydrate has been found in our drinking water supplies at levels up to 5 micrograms/1. The purpose of this study was to evalute the acute and subchronic toxicology of chloral hydrate in the random-bred CD-1 mouse, to provide data for risk assessment. The acute oral LD50 of this compound was 1442 and 1265 mg/kg in male and female mice, respectively.

Humoral and cell-mediated immune status in mice exposed to chloral hydrate.

Chloral hydrate has been found in our drinking water supplies at levels up to 5 micrograms/1. The purpose of this study was to evaluate the functional status of the immune system in random-bred CD-1 mice exposed to chloral hydrate for 14 and 90 days. Male mice, following 14 or 90 days of exposure to 1/10 and 1/100 the actual oral LD50, exhibited no alterations in either humoral or cell-mediated immunity.

In vivo assessment of immunotoxicity.

The organs, tissues, and cells of the lymphoreticular system have received considerable attention as targets for chemicals causing adverse effects. A basic toxicological approach is described for assessing the risk of a chemical perturbing the immune system. CD-1 mice were exposed for 14 or 90 days to one of several chlorinated hydrocarbons: 1,2-dichloroethane, 1,2-dichloroethylene or 1,1,2-trichloroethylene.

Uterine and peripheral blood concentrations of human chorionic gonadotropin and human placental lactogen.

One hypothesis is that two placental protein hormones (human placental lactogen and human chorionic gonadotropin) are effective immunosuppressive agents that prevents the rejection of a fetus because of their very high concentrations. In patients undergoing elective repeat cesarean sections at term, we measured the concentrations of these hormones in blood obtained simultaneously from draining ovarian veins and peripheral veins, and found no significant differences.

Effect of direct injection of neutrophils from uterine horns of rats containing intrauterine devices into recipient pregnant uteri.

The purpose of this study was to determine whether or not neutrophils from uterine horns containing an intruterine device (IUD) inhibit implantation of rat blastocysts. On day 4 (6:00 P.M.
