Hydroalcoholic extract from (Linn.) Medicus flower reverses sleep deprivation-evoked learning and memory deficit.

Previous researches have indicated that sleep plays a vital role in cognitive functions. Sleep deprivation (SD) causes learning and memory damage, which is associated with oxidative stress. This study was performed to investigate the neuroprotective effects of an extract of Abelmoschus manihot flower (EAM) against memory deficit induced by SD in mice.

CXCL3 overexpression promotes the tumorigenic potential of uterine cervical cancer cells via the MAPK/ERK pathway.

CXCL3 belongs to the CXC-type chemokine family and is known to play a multifaceted role in various human malignancies. While its clinical significance and mechanisms of action in uterine cervical cancer (UCC) remain unclear. This investigation demonstrated that the UCC cell line HeLa expressed CXCL3, and strong expression of CXCL3 was detected in UCC tissues relative to nontumor tissues.

[Expressions of HO-2 and CO in the corpus cavernosum of castrated rats].

Objective: To explore the expressions of HO-2 and CO in the corpus cavernosum of castrated rats in order to further study the pathogenesis of erectile dysfunction (ED).

Methods: We randomly divided 72 male SD rats into four groups: normal control, sham operation, castration, and castration + ZnPP. We detected intracavernous pressure (ICP) and penile erection in the basic condition and after apomorphine (APO) induction, determined the expression of the HO-2 protein in the corpus cavernosum by laser scanning confocal microscopy, and measured the level of CO by spectrophotometry during different periods of penile erection.

[Effects of ganoderma lucidum spores on cytochrome C and mitochondrial calcium in the testis of NIDDM rats].

Objective: To observe the effects of Ganoderma lucidum spores on Cytochrome C (Cyt-C) and mitochondrial calcium in the testis of NIDDM rats.

Methods: Fifty male Wistar rats were divided randomly into three groups: model, ganoderma and normal control, the first two groups injected with 2% STZ through vena caudalis, and the last one with half-and-half sodium citrate/citrate buffer solution. Two weeks after normal diet, glucose tolerance tests were performed and the rats with abnormal glucose tolerance from the model and ganoderma groups received high-fat and high-carbohydrate food, the ganoderma group given Ganoderma lucidum spores (250mg/[ kg x d] ) in addition, both for 10 weeks.
