Cyanobacterial blooms are detrimental events that affect the quality of water and the normal functioning of ecosystems, especially when dominated by toxin-producing species. Although cyanobacteria and cyanotoxins have been reported in the land-sea interface since the late 80s, genetic evidence on how inland freshwaters influence the cyanobacterial communities in these systems is very scarce to date. This study aims to investigate the relationship between the cyanobacterial communities of an inland freshwater reservoir and an estuary located in an aquaculture-rich coastal area of NW Spain.

This open-label, nonrandomized, two-period clinical mass balance and excretion study was used to investigate the excretion balance, PK, and metabolism of GSK3640254. Five healthy men received a single intravenous microtracer of 100 g [C]GSK3640254 with a concomitant oral nonradiolabeled 200-mg tablet followed by an oral 85-mg dose of [C]GSK3640254 14 days later.

Linerixibat, an oral small-molecule ileal bile acid transporter inhibitor under development for cholestatic pruritus in primary biliary cholangitis, was designed for minimal absorption from the intestine (site of pharmacological action). This study characterized the pharmacokinetics, absorption, metabolism, and excretion of [C]-linerixibat in humans after an intravenous microtracer concomitant with unlabeled oral tablets and [C]-linerixibat oral solution. Linerixibat exhibited absorption-limited flip-flop kinetics: longer oral versus intravenous half-life (6-7 hours vs.

We explore the effects on low-wage migrant workers (migrant workers) in three countries: Singapore, South Korea and Brazil, through the lens of the social determinants of health. Our analysis shows that governments missed key opportunities to mitigate pandemic risks for migrant workers.

This paper reports on a consultation meeting that discussed two emerging health issues of Nepali migrant workers in Malaysia and the ways they can be addressed. Primarily, it focused on the issue of sudden cardiac deaths of Nepali migrant workers in Malaysia. This issue has been raised internationally by both scientific and media in the recent years.

Six healthy men received a single intravenous microtracer of 10 g [C]nemiralisib with a concomitant inhaled nonradiolabeled 1000 g dose followed by an oral 800 g dose of [C]nemiralisib 14 days later. Complementary methods including accelerator mass spectrometry allowed characterization of a range of parameters including oral absorption (F), proportion of nemiralisib escaping gut wall metabolism (F), hepatic extraction (E), fraction of dose absorbed from inhaled dose (F), and renal clearance.

The excretion balance and pharmacokinetics of batefenterol using [ C]-radiolabeled drug administered orally and as intravenous (IV) infusion were assessed. In this 2-period, open-label study, 6 healthy male subjects received a single IV microtracer 1-hour infusion of 4 μg [ C]-batefenterol concomitant with inhaled nonradiolabeled batefenterol (1200 μg) followed by oral [ C]-batefenterol (200 μg) in period 2 after a 14-day washout.

Aims: GSK3191607, a novel inhibitor of the Plasmodium falciparum ATP4 (PfATP4) pathway, is being considered for development in humans. However, a key problem encountered during the preclinical evaluation of the compound was its inconsistent pharmacokinetic (PK) profile across preclinical species (mouse, rat and dog), which prevented reliable prediction of PK parameters in humans and precluded a well-founded assessment of the potential for clinical development of the compound. Therefore, an open-label microdose (100 μg, six subjects) first time in humans study was conducted to assess the human PK of GSK3191607 following intravenous administration of [14C]-GSK3191607.

Single oral administrations of up to 500 μg of vilanterol were shown to be safe and well tolerated in two clinical studies in healthy men. In a human radiolabel study, six healthy men received a single oral dose of 200 μg of [(14)C]vilanterol (74 kBq).
