Clinical outcomes after early ambulatory multidrug therapy for high-risk SARS-CoV-2 (COVID-19) infection.

There is an emergency need for early ambulatory treatment of Coronavirus Disease 2019 (COVID-19) in acutely ill patients in an attempt to reduce disease progression and the risks of hospitalization and death. Such management should be applied in high-risk patients age > 50 years or with one or more medical problems including cardiovascular disease. We evaluated a total of 922 outpatients from March to September 2020.

Multifaceted highly targeted sequential multidrug treatment of early ambulatory high-risk SARS-CoV-2 infection (COVID-19).

The SARS-CoV-2 virus spreading across the world has led to surges of COVID-19 illness, hospitalizations, and death. The complex and multifaceted pathophysiology of life-threatening COVID-19 illness including viral mediated organ damage, cytokine storm, and thrombosis warrants early interventions to address all components of the devastating illness. In countries where therapeutic nihilism is prevalent, patients endure escalating symptoms and without early treatment can succumb to delayed in-hospital care and death.

Non-clinical pharmacology and safety evaluation of TH9507, a human growth hormone-releasing factor analogue.

TH9507, an analogue of human growth hormone-releasing factor (hGRF1-44NH2) minimally modified by addition of a trans-3-hexenoyl moiety to Tyr1 of the amino acid sequence, was found to be resistant to dipeptidyl aminopeptidase-IV deactivation. Compared to natural hGRF1-44NH2, the modification slowed the in vitro degradation of the peptide in rat, dog and human plasma and prolonged the in vivo plasma elimination kinetics of immunoreactive TH9507. Plasma growth hormone and insulin-like growth factor-1 (IGF-1) markedly increased in pigs, rats and dogs after daily repeat intravenous or subcutaneous injections of TH9507 at doses up to 600 microg/kg.

Subchronic toxicity studies of sucrose acetate isobutyrate (SAIB) in the rat and dog.

Preliminary short-term toxicity studies of sucrose acetate isobutyrate (SAIB) in the dog demonstrated that addition of this additive to the diet was associated with an increase in liver size and elevated serum alkaline phosphatase activity with no evidence of pathological change by light microscopy. To determine the basis for these changes, a 12-week oral toxicity study of SAIB was conducted in the dog and a similar study was performed in the rat. SAIB was fed in the diet to groups of six beagle dogs of each sex at 0, 0.

Experimental studies on acute and chronic action of azelastine on nasal mucosa in guinea pigs, rats and dogs.

Azelastine (CAS 37932-96-0) nasal spray (Allergodil, Rhinolast, Astelin) was investigated in acute experiments in guinea pigs and after a 26-week local application period with daily repeated administration for effects on ciliary beat activity (acute experiments) and morphology of nasal mucosa. The commercially available spray did not inhibit ciliary beat activity in guinea pigs nor did it cause any inflammatory or atrophic changes after 26-week daily local application on nasal mucosa in rats and dogs.

Subchronic oral toxicity of di-n-octyl phthalate and di(2-Ethylhexyl) phthalate in the rat.

The subchronic oral toxicity of di(2-ethylhexyl) phthalate (DEHP) and di-n-octyl phthalate (DNOP) was studied. Groups of 10 male and 10 female Sprague-Dawley rats were administered DEHP in the diet at 0, 5, 50, 500 or 5000 ppm for 13 wk. In a separate study, groups of 10 male and 10 female Sprague-Dawley rats were given DNOP (5, 50, 500 and 5000 ppm) in the diet while control groups received basal diet containing 4% corn oil and positive control groups were fed a diet containing 5000 ppm DEHP.

A subchronic toxicity study of two inhaled aerosolized atropine sulfate formulations in rats and dogs.

The potential subchronic (21 days) toxicity of inhaled metered aerosol formulations (solution and suspension) of atropine sulfate was investigated in rats and dogs. The doses administered to rats were 0.78 and 2.

Toxicity of toxaphene in the rat and beagle dog.

Residues of the insecticidal mixture, toxaphene, have been found in Great Lakes fish. The purpose of the present study was to assess the subchronic toxicity of toxaphene in the rat and beagle dog. In the rat study, groups of 10 male and 10 female animals were fed diets containing 0, 4, 20, 100, or 500 ppm of the test compound for 13 weeks.

A three month inhalation toxicity study in the squirrel monkey (Saimiri sciureus) with terbutaline sulfate (Bricanyl).

A study of the subacute toxicity of inhaled terbutaline sulfate was performed in the Squirrel monkey (Saimiri sciureus). 3 groups of monkeys were exposed 1 h daily 7 days/week for 3 months to terbutaline sulfate aerosols at concentrations of 0.039, 0.

Studies on the spring rise phenomenon in ovine helminthiasis. I. Spring rise in stabled sheep.

Serial ova count studies were conducted to determine some of the characteristics of the spring rise in faecal shedding of nematode ova by parasitized sheep in flocks in the Montreal area. It was discovered that substantial spring rises occurred in most ewes following their lambing but that great variation existed in the magnitude, duration, and pattern of the rises. Although rams did not display increased ova counts, a slight but well-defined rise developed in one unbred ewe.
