An autophagic deficit in the uterine vessel microenvironment provokes hyperpermeability through deregulated VEGFA, NOS1, and CTNNB1.

The uterus undergoes vascular changes during the reproductive cycle and pregnancy. Steroid hormone deprivation induces macroautophagy/autophagy in major uterine cell types. Herein, we explored the functions of uterine autophagy using the -driven deletion model.

Autophagic regulation in steroid hormone-responsive systems.

Two female sex steroid hormones, estrogen and progesterone, are crucial regulators of many physiological functions of reproductive organs. These two hormones are versatile factors linking growth, differentiation, metabolism, and death of cells in the uterus. In recent years, it has become evident that autophagy is involved in the effects of estrogen and progesterone on various cellular events in reproductive organs.

Paenibacillus swuensis sp. nov., a bacterium isolated from soil.

Strain DY6(T), a Gram-positive endospore-forming motile rod-shaped bacterium, was isolated from soil in South Korea and characterized to determine its taxonomic position. Phylogenetic analyses based on the 16S rRNA gene sequence of strain DY6(T) revealed that strain DY6(T) belongs to the genus Paenibacillus in the family Paenibacillaceae in the class Bacilli. The highest degree of sequence similarities of strain DY6(T) were found with Paenibacillus gansuensis B518(T) (97.

Effects of abutment screw coating on implant preload.

Purpose: The aim of the present study was to investigate the effects of tungsten carbide carbon (WC/CTa) screw surface coating on abutment screw preload in three implant connection systems in comparison to noncoated titanium alloy (Ta) screws.

Materials And Methods: Preload of WC/CTa abutment screws was compared to noncoated Ta screws in three implant connection systems. The differences in preloads were measured in tightening rotational angle, compression force, initial screw removal torque, and postload screw removal torque after 1 million cyclic loads.

Significance of p-STAT3 expression in human colorectal adenocarcinoma.

To examine the relationship between p-STAT3 and the clinicopathological parameters of colorectal adenocarcinoma (CRA), we initially conducted immunohistochemical (IHC) analyses on formalin-fixed tissues. A total of 127 invasive CRA, 20 colorectal adenomas and 20 normal mucosae were obtained. To clarify the validity of p-STAT3 as determined by the IHC analysis, quantitative real-time PCR was performed on fresh samples from 51 CRA-4 carcinomas in situ, 47 invasive CRA and on 51 normal mucosae.
