Central pockets were defined as small, loop-enclosed whorls whose quantitative values must not exceed the third part of the quantitative value of the loop or as small, whorl-like patterns in the core of a loop having at least one curved ridge with its convexity towards the opening of the loop. Applying this classification scheme, the frequency of central pockets was found to be 17.5% in 200 males and 17.0% in 200 females, but was significantly higher in a sample of 21 male and 22 female pairs of MZ twins (33.2% and 34.1%, respectively). Twin as well as family data (94 families with 269 children) pointed to a rather weak hereditary influence upon the formation of central pockets. Rudimentary central pockets occurred in 9.5% of males and 10.0% of females. Since no common genetic basis could be established for central pockets and rudimentary central pockets, the latter should not be scored as central pockets.

Under conditions that are close to the real cellular environment, the human telomeric single-stranded overhang (∼200 nt) consisting of tens of TTAGGG repeats tends to form higher order structures of multiple G-quadruplex (G4) blocks. On account of the higher biological relevance of higher order G4 structures, ligand compounds binding to higher order G4 are significant for the drug design toward inhibiting telomerase activity. Here, we study the interaction between a cationic porphyrin derivative, 5,10,15,20-tetra{4-[2-(1-methyl-1-piperidinyl)propoxy]phenyl}porphyrin (T4), and a human telomeric G4-dimer (AG(TAG)) in the mimic intracellular molecularly crowded environment (PEG as a crowding agent) and K or Na solution (i.

Background: In implant-based breast surgery, microbial contamination of implant surfaces predisposes complications such as overt periprosthetic infection and has been linked to capsular contracture (CC). Anti-microbial practices, including povidone-iodine (PVP-I) breast pocket irrigation, are routinely employed to minimise these risks. No standardised protocol for using this antiseptic exists, particularly concerning the ideal concentration.

Benzotriazole ultraviolet stabilizers (BUVSs) are pervasive environmental contaminants that pose significant risks to human health. This study evaluated the effects of three typical BUVSs (UV-328, UV-329, and UV-P) on human mesenchymal stem cells (hMSCs), which play crucial roles in tissue maintenance and repair. hMSCs were exposed to BUVSs across a range of concentrations, and their maintenance and differentiation capacities were assessed.

OaPAC, the photoactivated adenylyl cyclase from , is composed of a blue light using FAD (BLUF) domain fused to an adenylate cyclase (AC) domain. Since both the BLUF and AC domains are part of the same protein, OaPAC is a model for understanding how the ultrafast modulation of the chromophore binding pocket caused by photoexcitation results in the activation of the output domain on the μs-s time scale. In the present work, we use unnatural amino acid mutagenesis to identify specific sites in the protein that are involved in transducing the signal from the FAD binding site to the ATP binding site.
