[Resveratrol protects human sperm against cryopreservation-induced injury].

Objective: To investigate the effects of resveratrol in the cryopreservation medium on the quality and function of post-thaw sperm.

Methods: Semen samples were obtained from 50 normozoospermic and 50 oligoasthenozoospermic men, liquefied and then cryopreserved in the glycerol-egg yolk-citrate (GEYC) medium with or without 30 μmol/L resveratrol. Sperm motility, viability and acrosome reaction (AR) were examined before and after thawing.

Lentivirus‑mediated RIG‑I knockdown relieves cell proliferation inhibition, cell cycle arrest and apoptosis in ATRA‑induced NB4 cells via the AKT‑FOXO3A signaling pathway in vitro.

Retinoic acid inducible gene I (RIG‑I) is upregulated during all‑trans retinoic acid (ATRA)‑induced terminal granulocytic differentiation of NB4 acute promyelocytic leukemia (APL) cells. However, the function and mechanism of RIG‑I in NB4 cells remains to be fully elucidated. In the present study, lentivirus‑mediated RIG‑I‑knockdown was used to investigate the proliferation, cell cycle and apoptotic processes of ATRA‑induced NB4 cells in vitro using an MTT assay and flow cytometry, respectively.

[Effect of angong niuhuang pill as an adjuvant treatment on moderate or severe neonatal hypoxic-ischemic Encephalopathy].

Objective: To evaluate the clinical efficacy and safety of angong niuhuang pill (ANP) as an adjuvant treatment on moderate or severe neonatal hypoxic-ischemic encephalopathy (NHIE).

Methods: Thirty-nine neonates with NHIE in the control group were treated with conventional treatment, and 58 in the treated group were administered orally ANP additionally, and relative indexes were observed.

Results: The improvement of aspects such as recovery of consciousness, muscular tension, and primitive reflex and disappearance of convulsion, in the treated group was better than that in the control group (P < 0.

Molecular cloning of Bral2, a novel brain-specific link protein, and immunohistochemical colocalization with brevican in perineuronal nets.

The hyaluronan binding chondroitin sulphate proteoglycans, called lecticans, are the abundant extracellular matrix molecules in the developing and/or adult brain. The link proteins (LPs) are also known to be coordinately present in brain. We report here the molecular cloning and expression analysis of a novel member of LPs: Bral2, predominantly expressed in brain.

Bral1, a brain-specific link protein, colocalizing with the versican V2 isoform at the nodes of Ranvier in developing and adult mouse central nervous systems.

Bral1, a brain-specific hyaluronan-binding protein, has been cloned recently. To gain insight into the role of Bral1, we generated a specific antibody against this protein. We have examined the detailed localization pattern of Bral1 protein and compared it with that of other members of the lectican proteoglycan family, such as brevican and versican, with which Bral1 is predicted to interact.
