Schisanhenol improves early porcine embryo development by regulating the phosphorylation level of MAPK.

Schisanhenol (SAL), a biphenyl cyclooctene-type lignin compound which can be extracted and isolated from many plants of the Schisandra family, exhibits a variety of biological activities including anti chronic cough, night sweating, thirst, diabetes, and obesity. However, its effects on the female reproductive system are unclear. Previous studies showed that SAL had potential antioxidant activity in heart, liver, and brain.

Carnosic acid improves porcine early embryonic development by inhibiting the accumulation of reactive oxygen species.

Carnosic acid (CA), a natural catechol rosin diterpene, is used as an additive in animal feeds and human foods. However, the effects of CA on mammalian reproductive processes, especially early embryonic development, are unclear. In this study, we added CA to parthenogenetically activated porcine embryos in an in vitro culture medium to explore the influence of CA on apoptosis, proliferation, blastocyst formation, reactive oxygen species (ROS) levels, glutathione (GSH) levels, mitochondrial membrane potential, and embryonic development-related gene expression.

CPEB3 regulates the proliferation and apoptosis of bovine cumulus cells.

Cytoplasmic polyadenylation element-binding protein 3 (CPEB3) is a member of the Cytoplasmic polyadenylation element-binding family, which has been found to regulate the translation of dormant and masked mRNA in Xenopus oocytes and plays potential roles in regulating biological functions in cells and tissues. However, its role in cumulus cells is not clear. In this study, the mRNA expression of CPEB3 in bovine cumulus cells was inhibited with small interfering RNA.

[Effect of electroacupuncture on diaphragmatic function in patients with post-stroke tracheotomy].

Objective: To observe the effect of electroacupuncture (EA) on diaphragmatic function based on conventional treatment in patients with poststroke tracheotomy tube.

Methods: A total of 70 patients were randomized into an observation group (35 cases) and a control group (34 cases, 1 case dropped off). Internal medical basic treatment and breathing training were given in both groups.

[Effect of "Tongyuan" acupuncture treatment on success rate of extubation in stroke patients undergoing tracheotomy].

Objective: To observe the impact of "Tongyuan" (regulating the Governor Vessel to tranquilize mental activities, conducting back to its origin) acupuncture treatment on cough reflex, pulmonary infection and swallowing function in stroke patients undergoing tracheotomy.

Methods: Seventy-four cerebral stroke patients with tracheo-tomy were randomly allocated to scalp acupuncture and "Tongyuan" acupuncture groups (=37 in each group). All the patients of the two groups received basic treatment, including treatment of primary diseases, routine nursing, respiratory muscle training, physical therapy, acupuncture of Chize (LU5), Quchi (LI11), Hegu (LI4), Weizhong (BL40), Zusanli (ST36).

COL1A1 affects apoptosis by regulating oxidative stress and autophagy in bovine cumulus cells.

The collagen type I alpha 1 chain (COL1A1), as a major component of extracellular matrix, plays a potential role in the growth and development of bovine follicles. However, its specific role in bovine cumulus cells remains unclear. In this study, we examined apoptosis, the cell cycle and reactive oxygen species after inhibition of COL1A1 expression by siRNA in bovine cumulus cells.

Synonymous mutation adenomatous polyposis coliΔ486s affects exon splicing and may predispose patients to adenomatous polyposis coli/mutY DNA glycosylase mutation‑negative familial adenomatous polyposis.

Familial adenomatous polyposis (FAP) is an autosomal dominant‑inherited colorectal cancer. Recent advances in genetics have indicated that the majority of patients with FAP carry germline mutations of the adenomatous polyposis coli (APC) and mutY DNA glycosylase (MUTYH) genes. However, a large subset of families with a history of FAP have undetectable pathogenic alterations, termed APC/MUTYH mutation‑negative FAP.
