Pharmacokinetic and Safety Profile of the Novel HIV Non-Nucleoside Reverse Transcriptase Inhibitor MK-8507 in Adults without HIV.

Antimicrob Agents Chemother 2021 Sep 13:AAC0093521. Epub 2021 Sep 13.

Merck & Co., Inc., Kenilworth, NJ, USA.

MK-8507 is a novel HIV-1 non-nucleoside reverse transcriptase inhibitor in clinical development with potential for once-weekly oral administration for the treatment of HIV-1 infection. Two randomized, double-blind, placebo-controlled phase 1 studies in adults without HIV-1 evaluated the safety, tolerability, and pharmacokinetics of single and multiple doses of MK-8507; drug interaction with midazolam (a cytochrome P450 3A4 substrate) and food effect were also assessed. In Study 1, 16 participants received oral ascending single doses of MK-8507 (2-400 mg) or placebo in an alternating fashion. Read More

Seminal Plasma Does Not Influence Canine Semen Stored at 5°C for Long-Term Conservation.

Biopreserv Biobank 2021 Sep 9. Epub 2021 Sep 9.

Department of Veterinary Surgery and Animal Reproduction, Faculty of Veterinary Medicine and Animal Science, São Paulo State University (UNESP), Botucatu, Brazil.

Seminal plasma has several components that protect the sperm cells and assist in the fertilization process. In contrast, the exact role carried out by seminal plasma during the cooling of canine semen remains controversial. Moreover, concerning the long estrus period, the possibility to store chilled semen at 5C for more than 72 hours and maintain good sperm quality for additional inseminations could increase fertilization rates.

Comparison of skeletal muscle ultrastructural changes between normal and blood flow restricted resistance exercise: A case report.

Exp Physiol 2021 Aug 26. Epub 2021 Aug 26.

School of Exercise and Sport Science, University of Mary Hardin-Baylor, Belton, TX, USA.

New Findings: What is the main observation in this case? The main observation of this case report is that blood flow restriction exercise can cause myofibrils to have an aberrant wave-like appearance that is accompanied by irregular pockets of sarcoplasm in the intermyofibrillar space while traditional forms of damage to the Z-discs and contractile elements are not as apparent. What insights does it reveal? Our finding indicate blood flow restriction mediated fluid pooling may cause alterations in skeletal muscle ultrastructure after exercise that may be directly related to myofiber swelling.

Abstract: The acute effects of blood flow restriction training (BFR) on skeletal muscle ultrastructure are poorly understood due to inconsistent findings and the use of largely imprecise systemic targets for indication. Read More

Stability of Dexmedetomidine in Polyvinyl Chloride Bags Containing 0.9% Sodium Chloride Intended for Subcutaneous Infusions.

Int J Pharm Compd 2021 Jul-Aug;25(4):330-335

Department of Pharmacy, The Ottawa Hospital, The Ottawa Hospital Research Institute, Ottawa, ON, Canada.

Dexmedetomidine is a sedative medication with co-analgesic effects that has been used primarily in critical care and anesthesia as a continuous intravenous infusion. Its utility in the treatment of refractory agitated delirium is being investigated in other settings including palliative care, but continuous intravenous infusions are not always feasible during end-of-life care. Subcutaneous infusions are more commonly used in this setting, but smaller volumes and higher concentrations are typically required. Read More
