Background: Oxidative aggression is a hallmark of varicocele and may depend on decreased reactive ability of the endogenous antioxidant system following heat stress. We aimed to investigate the underlying mechanisms. Therefore, the expression of the main enzyme proteins involved in the generation of endogenous antioxidant power, cystathionine beta-synthase (CBS), cystathionine gamma-lyase (CSE), heme oxygenase (HO-1), and also, some of the metabolites (methionine, homocysteine, taurine and vitamin B6) reporting on their activity was investigated using a surgical varicocele model in rats.

Background: Although mice are used extensively to study atherosclerosis of different vascular beds, limited data is published on the occurrence of intracranial atherosclerosis. Since intracranial atherosclerosis is a common cause of stroke and is associated with dementia, a relevant animal model is needed to study these diseases.
Methods And Results: We examined the presence of intracranial atherosclerosis in different atherogenic mouse strains and studied differences in vessel wall characteristics in mouse and human tissue in search for possible explanations for the different atherosclerotic susceptibility between extracranial and intracranial vessels.
A High-Efficiency Autocatalysis-Oriented Cascade Circuit via Reciprocal Hug-Amplification for Assay-to-Treat Application.

Developing a DNA autocatalysis-oriented cascade circuit (AOCC) via reciprocal navigation of two enzyme-free hug-amplifiers might be desirable for constructing a rapid, efficient, and sensitive assay-to-treat platform. In response to a specific trigger (), seven functional DNA hairpins were designed to execute three-branched assembly (TBA) and three isotropic hybridization chain reaction (3HCR) events for operating the AOCC. This was because three new inducers were reconstructed in TBA arms to initiate 3HCR (TBA-to-3HCR) and periodic repeats were resultantly reassembled in the tandem nicks of polymeric nanowires to rapidly activate TBA in the opposite direction (3HCR-to-TBA) without steric hindrance, thereby cooperatively manipulating sustainable AOCC progress for exponential hug-amplification (1:3).

Objectives: Sulforaphane (SFN), an isothiocyanate in cruciferous plants, has been reported to be effective in treating central nervous system diseases. However, how SFN protects the central nervous system needs further study. The aim of this study was to investigate the neuroprotective effect of SFN and its possible mechanism of action.

Schizophrenia is a complex neuropsychiatric disorder featuring enhanced brain oxidative stress and deficient reelin protein. GFAP.HMOX1 mice that overexpress heme oxygenase-1 (HO-1) in astrocytes manifest a schizophrenia-like neurochemical, neuropathological and behavioral phenotype including brain oxidative stress and reelin downregulation.
