Ethical objections to sex selection for nonmedical reasons [PDF]
, 2008 This paper examines the main ethical argument used to support the use of sex selection for non-medical reasons, namely that sex selection for non-medical reasons should be allowed on the grounds of reproductive autonomy.

FEBS Letters, EarlyView.Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Structural and biochemical analysis of a B12 superbinder
FEBS Letters, EarlyView.BtuG proteins are vitamin B12 scavengers in Bacteroides thetaiotaomicron, a dominant human gut bacterium. We present crystal structures of three BtuG homologs bound to cobalamin and its precursor cobinamide, revealing picomolar binding affinities, among the highest known for any natural protein.

Journal of Fisheries, 2016 Size at first maturity of Terapon jarbua was studied based on 114 male (14 to 28 cm in TL) and 140 female (14 to 32 cm in TL). The Logistic curves describing the relationship between the sexes and the proportion of 50% maturity (Lm50) were estimated at ...

FEBS Letters, EarlyView.Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Testis and brain steroidogenesis during the reproductive cycle of pelophylax esculentus
, 2018 The anuran amphibian Pelophylax esculentus shows an annual cycle of both sexual steroid production and spermatogenesis. Plasma testosterone levels are low in the non-breeding period and high during the breeding period, while 17ß-estradiol levels show an ...

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation
FEBS Letters, EarlyView.Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Reproductive Cycle Stage Assessment in the Two-Toed Sloth (Choloepus Hoffmanni, Preliminary Results
The number of two-toed sloths (Choloepus hoffmanni) has significantly decreased in the last years. Deepening the knowledge of this tropical mammal's reproductive physiology is essential to improve captive breeding within conservation programs for this ...

Environment InternationalThe link between per- and polyfluoroalkyl substances (PFAS) and impaired sperm quality has been disputable, partially attributed to the relatively small sample size and the lack of knowledge on exposure status in the microenvironment of target site. Here,
