We show how to effectively introduce a proper description of the velocity-changing collisions into the model of isolated molecular transition for the case of self- and Ar-perturbed H2. We demonstrate that the billiard-ball (BB) approximation of the H2-H2 and H2-Ar potentials gives an accurate description of the velocity-changing collisions. The BB model results are compared with ab initio class...

We present Far Ultraviolet Spectroscopic Explorer (FUSE) observations of interstellar molecular hydrogen (H2) in two Galactic high-velocity clouds (HVCs). Molecular hydrogen absorption is detected in the Magellanic Stream (abundance ∼ 0.3 solar) toward the Seyfert galaxy Fairall 9 in the lowest three rotational states (J = 0− 2) at vLSR = +190 kms , yielding a total H2 column density of log N(H...

BACKGROUND Sperm motility is a critical factor in male fertility. Low motility can be caused by a variety factors including abnormal spermatogenesis, oxidative damage, or depletion of intracellular ATP. Recent findings indicate that hydrogen molecule (H2) selectively reduces toxic reactive oxygen species. In this study, we investigated the effects of H2 on human sperm motility in vitro. METHO...

AIMS/INTRODUCTION In previous studies, hydrogen gas (H2) administration has clearly shown effectiveness in inhibiting diabetes. Here, we evaluated whether subcutaneous injection of H2 shows enhanced efficacy against type 2 diabetes mellitus induced in mice by a high-fat diet and low-dose streptozotocin treatment. MATERIAL AND METHODS H2 was injected subcutaneously at a dose of 1 mL/mouse/week...

The spatial organization of the genome within the eukaryotic nucleus is a dynamic process that plays a central role in cellular processes such as gene expression, DNA replication, and chromosome segregation. Condensins are conserved multi-subunit protein complexes that contribute to chromosome organization by regulating chromosome compaction and homolog pairing. Previous work in our laboratory ...
