Uniform cubic, octahedral, and star‐like copper sulfide mesocages with single‐crystalline shells (see figure) are synthesized by the sulfidation of various shape‐controlled Cu2O crystals into Cu2O/CuxS core/shell structures, followed by the removal of the inner Cu2O cores. Potential applications of these materials in solar energy conversion, optics, and sensors are envisaged.

For women with lymph node-negative, ER-positive breast cancer, obesity was not associated with a material increase in recurrence risk or a change in tamoxifen efficacy. However, because obesity was associated with increased risks of contralateral breast cancer, of other primary cancers, and of overall mortality, it may influence long-term outcomes for breast cancer survivors.

It is butyrate, instead of other substances produced by F. prausnitzii, that maintains Th17/Treg balance and exerts significant anti-inflammatory effects in colorectal colitis rodents, by inhibiting HDAC1 to promote Foxp3 and block the IL-6/STAT3/IL-17 downstream pathway. F. prausnitzii could be an option for further investigation for IBD treatment. Targeting the butyrate-HDAC1-T-cell axis offers an effective novel approach in the treatment of inflammatory disease.

NAFLD is prevalent in the nonobese Chinese population, and a substantial proportion of subjects developed NAFLD over the 5-year follow-up period. Special attention should be paid to the factors associated with the presence and development of NAFLD in nonobese subjects, to improve prevention and management of NAFLD.
