Pharmacokinetics and safety of daptomycin administered subcutaneously in healthy volunteers: a single-blinded randomized crossover trial.

Background: Daptomycin stands as a key IV antibiotic in treating MRSA infections. However, patients facing challenges with difficult venous access require alternative administration routes. This study aimed to evaluate the pharmacokinetic (PK) profile and safety of subcutaneous (SC) daptomycin.

Bioavailability of dissolved and crushed single tablets of bictegravir, emtricitabine, tenofovir alafenamide in healthy adults: the SOLUBIC randomized crossover study.

Background: Crushing or dissolving bictegravir/tenofovir alafenamide/emtricitabine (BIC/TAF/FTC) tablets is not recommended because there are no data supporting this practice.

Methods: A crossover, randomized trial in healthy adults (NCT04244448) investigated the bioavailability of two off-label uses of BIC/TAF/FTC (50/200/25 mg), dissolved in water or crushed in apple compote, compared with the solid tablet. Pharmacokinetic (PK) parameters were estimated from sequential intensive plasma antiretroviral concentrations over a 72 h period post dose.

Effect of Tenofovir Disoproxil Fumarate and Emtricitabine on nasopharyngeal SARS-CoV-2 viral load burden amongst outpatients with COVID-19: A pilot, randomized, open-label phase 2 trial.

Background: Tenofovir and emtricitabine interfere with the SARS CoV-2 ribonucleic acid (RNA)-dependent RNA polymerase (RdRp). Several cohorts reported that people treated by tenofovir disoproxil fumarate and emtricitabine are less likely to develop SARS CoV-2 infection and related severe COVID-19.

Methods: We conducted a pilot randomized, open-label, controlled, phase 2 trial at two hospitals in France.

Real versus sham proximal biofield therapy in the treatment of warts of the hands and feet in adults: study protocol for a randomized controlled trial (MAGNETIK study).

Background: Despite the lack of scientific studies on biofield therapies, they are widely acclaimed by patients. The mechanisms of action are not explained by current allopathic medical approaches. Warts are common and contagious viral lesions that may be refractory to standard dermatologic treatments such as cryotherapy, laser therapy, and keratolytic ointments.

Protein kinase C regulation of glypican-1, syndecan-1 and syndecan-4 mRNAs expression during rat Sertoli cell development.

Our previous studies indicated that cell surface proteoglycans were mostly heparan sulfate ones (HSPG) in 20 day-old Sertoli cells [Biochim. Biophys. Acta 1510 (2001) 474].

Regulation of glypican-1, syndecan-1 and syndecan-4 mRNAs expression by follicle-stimulating hormone, cAMP increase and calcium influx during rat Sertoli cell development.

In seminiferous tubules, Sertoli cells provide structural and nutritional support for the developing germinal cells. Cell- to-cell signaling and cell adhesion require proteoglycans expressed at the cell membrane. A preliminary biochemical and structural approach indicated that cell surface proteoglycans are mostly heparan sulfate proteoglycans (HSPG).

Cell surface heparan sulfate proteoglycans: target and partners of the basic fibroblast growth factor in rat Sertoli cells.

Basic fibroblast growth factor (bFGF) regulates diversified biological functions in rat Sertoli cells. This report demonstrates that bFGF inhibits steroidogenesis in developing rat Sertoli cells. Follicle stimulating hormone (FSH)-stimulated estradiol production was reduced by bFGF.
