Insight into the Characteristic Components of Cigar Tobacco.

As an important agricultural product, cigar tobacco lacks reports on chemical compositions. The investigation on characteristic components of Yunnan local cigar tobacco revealed 15 Cembrane-type diterpenes including nine undescribed ones (-). Their structures were elucidated on the basis of extensive spectroscopic analysis, computational calculations, and X-ray diffraction.

Clonally expanded, targetable, natural killer-like NKG7 T cells seed the aged spinal cord to disrupt myeloid-dependent wound healing.

Spinal cord injury (SCI) increasingly affects aged individuals, where functional impairment and mortality are highest. However, the aging-dependent mechanisms underpinning tissue damage remain elusive. Here, we find that natural killer-like T (NKLT) cells seed the intact aged human and murine spinal cord and multiply further after injury.

Age- and Gender-Related Femoral Bowing Analysis in the Korean Population and Features for Clinical Applications.

: The anterolateral bowing of the femur shows differences between races and has recently caused many clinical problems. Asians tend to have increased femoral bowing, but there is a lack of large-scale studies. We aim to identify the patterns of femoral bowing in the Korean population through comprehensive analysis and address its clinical implications.

Solvent-free upcycling of agricultural plastic waste using in situ self-assembly metal nanoparticles co-doped microporous carbocatalyst for advanced transportation fuels.

Plastic mulching film is ubiquitous in modern agriculture for its heat preservation and moisture retention functions. However, plastic mulching film waste accumulated on land results in microplastic pollution, posing potential hazards as these micro and nanoplastics can enter the food chain. Chemical upcycling of waste mulching film is an emerging strategy to realize sustainable development and circular economy.
