The construction of isotypic high-nuclearity inorganic cages with identical pristine parent structure and increasing nuclearity is highly important for molecular growth and structure-property relationship study, yet it still remains a great challenge. Here, we provide an in situ growth approach for successfully synthesizing a series of new giant hollow polymolybdate dodecahedral cages, , , and , whose structures are growth based on giant polymolybdate cage . Remarkably, they show two pathways of nuclear growth based on , that is, the growth of 10 and 20 Mo centers on the inner and outer surfaces to afford and , respectively, and the growth of 10 Mo centers both on the inner and outer surfaces to give .

Delayed recovery from ulcerative colitis is mainly due to impaired healing of the intestinal epithelium after inflammation. The circadian rhythm controls cell proliferation and energy metabolism. However, the role of circadian genes in inflammatory bowel disease is largely unknown.

Objectives: Previous studies of the associations between white matter hyperintensities (WMH) and chronic kidney disease (CKD) were still conflicting; therefore, our study aimed to conduct a systematic review of all of the available research on this topic and a meta-analysis of the association between WMH and CKD among observational studies.

Setting And Design: Systematic review and meta-analysis.

Outcome Measures: Severity of WMH.

Article Synopsis
  • A study was conducted to evaluate the safety of COVID-19 vaccine boosters using four different types of vaccines among participants in China.
  • The results showed that participants receiving adenovirus and protein subunit vaccines had a higher risk of adverse reactions compared to those receiving a booster of the same inactivated vaccine.
  • While most side effects were mild, the findings indicated that using a different type of vaccine for the booster increased the risk of reactions, highlighting the importance of considering booster strategies carefully.

An innovative strategy allowing the development of a new generation of easy-to-prepare and easy-to-use nano-sized catalysts with high tenability is presented. This strategy is based on the formation of hybrid polyion complexes (HPICs) from the complexation of copper with a block copolymer consisting of an ionizable complexing block and a neutral stabilizer block. These complexes have a well-defined structure and size with a hydrodynamic diameter around 29 nm.

Intestinal fibrosis is a common complication of inflammatory bowel disease (IBD), resulting in strictures and ultimately obstruction, which is a significant clinical problem. Fibrosis is mainly triggered by local chronic inflammation and occurs when excessive extracellular matrix deposition is caused by activated mesenchymal cells. Despite the advance of anti-inflammatory therapies in IBD, the incidence and preventive strategies of intestinal fibrosis and strictures in IBD have not significantly changed over time.

This study was conducted to investigate expression of matrix metalloproteinases (MMPs) and ovarian morphological changes in androgenized cyclic female guinea pigs. Adult cyclic female guinea pigs were injected daily for 28 days with medium doses of testosterone propionate (TP; 1 mg/100g), high doses of TP (2 mg/100g), or saline (control). Serum concentrations of testosterone, estradiol (E2), and progesterone (P4) were measured.

The effects of equine chorionic gonadotropin (eCG) on follicular development and ovulation in cyclic guinea pigs were investigated by histological and immunohistochemical analyses. Three groups of guinea pigs (n=12) were administrated subcutaneously with saline, 20 or 50 IU of eCG, respectively, on cyclic Day 12 (Day 1=vaginal openings). Ovaries were collected at 4 and 8 d after administration (6 animals per group each time).
