Chemical analysis of different parts from agarwood columns by artificially agarwood-inducing method based on GC-MS and UPLC-TOF-MS.

Agarwood is resin-containing wood produced by plants that have been injured. It is widely used in herbal medicine, incense, decorative items, and so on. In this study, we conducted resin area statistical analysis, determined starch particle and reducing sugar contents, and performed multivariate statistical analysis of chemical composition by GC-MS and UPLC-Q-TOF-MS to explore the different components in sections cut from an agarwood column, designated as A1-A4.

WeiNaiAn capsule attenuates intestinal mucosal injury and regulates gut microbiome in indomethacin-induced rat.

Indomethacin, as a non-steroidal anti-inflammatory drugs, is widely used in the clinic. However, it can cause severe injury to the gastrointestinal tract and the incidence is increasing. It has become an essential clinical problem in preventing intestinal damage.

The biological characteristics of chicken embryo mesenchymal stem cells isolated from chorioallantoic membrane.

Mesenchymal stem cells (MSCs) derived from fetal membranes (FMs) have the potential to exhibit immunosuppression, improve blood flow, and increase capillary density during transplantation. In the field of medicine, opening up new avenues for disease treatment. Chicken embryo chorioallantoic membrane (CAM), as an important component of avian species FM structure, has become a stable tissue engineering material in vivo angiogenesis, drug delivery, and toxicology studies.

Systematic investigation of TetR-family transcriptional regulators and their roles on lignocellulosic inhibitor acetate tolerance in .

TetR-family transcriptional regulators are widely distributed among bacteria and involved in various cellular processes such as multidrug and inhibitor resistance. is a industrial bacterium for lignocellulosic ethanol production. Although TetR-family regulators and their associated RND-family efflux pumps in have been identified to be differentially expressed under various inhibitors and stressful conditions, there are no systematic investigation yet.

Research progress of robot and laparoscope in postoperative complications of rectal cancer.

Rectal cancer is one of the most common malignant tumours worldwide, and it is also one of the major diseases that seriously threatens human life and health. At present, the main treatment for rectal cancer is still surgical treatment. The surgical methods have been rapidly developed from the previous open surgery to the current minimally invasive surgery.

Electrochemical properties and facile preparation of hollow porous VO microspheres for lithium-ion batteries.

Vanadium pentoxide (VO) has shown great potential to be used in lithium-ion batteries (LIBs), but it has limited applications because it has cycle instability and poor rate capability, and its lithiation mechanism is not well understood. In this work, hollow porous VO microspheres (HPVOM) were obtained by a facile poly(vinylpyrrolidone) and ethylene glycol-assisted soft-template solvothermal method. Half cells with HPVOM exhibited good capacity, rate capability, and stability, delivering 407.

Relationship between the UPLC Fingerprints of "Chachi" Leaves and Their Antioxidant Activities.

"Chachi" (CRC) leaves contain abundant flavonoids, indicating that they possess good nutritional/pharmacological research and development potential. This study aims to explore chemical antioxidant quality markers based on the spectrum-effect relationship and quality control strategy of CRC leaves. The ultrahigh performance liquid chromatography (UPLC) system was used to establish chromatographic fingerprints of "Chachi" leaves.

Correlation between Inflorescence Architecture and Floral Asymmetry-Evidence from Aberrant Flowers in L. (Cannaceae).

Floral symmetry studies often focus on the development of monosymmetric and polysymmetric flowers, whereas asymmetric flowers and their position and function within the inflorescence structure are largely neglected. Cannaceae is one of the few families that possesses truly asymmetric flowers, serving as a model to study the characters and mechanisms involved in the development of floral asymmetry and its context within the developing and mature inflorescence. In this study, inflorescence structure and floral morphology of normal asymmetric flowers and 16 aberrant flower collections from L.
