Loss of Mist1 alters the characteristics of Paneth cells and impacts the function of intestinal stem cells in physiological conditions and after radiation injury.

Intestinal stem cells (ISCs) and Paneth cells (PCs) reside at the bottom of the crypts of Lieberkühn in the small intestine. Recent studies have shown that the transcription factor Mist1, also named BHLHA15, plays an important role in the maturation of PCs. Since there is an intimate interaction between PCs and ISCs, we speculated that the loss of Mist1 could impact these two neighboring cell types.

Lycopene protects against ionizing radiation-induced testicular damage by inhibition of apoptosis and mitochondrial dysfunction.

Ionizing radiation (IR) is one of the key contributors that cause male infertility by disturbing spermatogenesis. Lycopene, a carotenoid with strong antioxidant properties, was shown to protect against oxidative damage induced by IR in several experimental models. The present study was designed to explore the possible protective effects of lycopene against IR-induced testicular damage in C57BL/6 mice.

Malignant triton tumor of uterus: A case report and literature review.

Malignant triton tumor (MTT) is a highly aggressive malignant neoplasm, classified as a variant of malignant peripheral nerve sheath tumor with rhabdomyoblastic differentiation. There are few reports that MTT occurred in urogenital system. In the present study, we report the first MTT occurring in the uterus.

MBP-activated autoimmunity plays a role in arsenic-induced peripheral neuropathy and the potential protective effect of mecobalamin.

Intake excessive arsenic (As) is related to the occurrence of peripheral neuropathy. However, both the underlying mechanism and the preventive approach remain largely unknown. In the present study, As treatment significantly decreased the mechanical withdrawal threshold and increased the titer of anti-myelin basic protein antibody in rats, accompanied with damaged BNB.

Association of twenty-three plasma elements with fasting serum glucose among Chinese population from four areas with different pollution level.

Background: Association between fasting serum glucose (FSG) and certain mineral elements has been extensively reported. Investigation regarding multi-element exposure among subjects with different exposure level is warranted to confirm the association and further explore dose-dependent relationship.

Methods: A total of 3488 participants were recruited from four counties of Hunan province, South China.

Sex-specific influence of prenatal air pollutant exposure on neonatal neurobehavioral development and the sensitive window.

Increasing evidence indicates the adverse effect of air pollution exposure during pregnancy on neurologic development among children. However, the impact on neurobehavioral development in fetus remains unknown. In 2017, a total of 1193 mother-newborns pairs were enrolled in a birth cohort study in Changsha, China.
