The Antiobesity Effects and Potential Mechanisms of Theaflavins
Jinghua Peng,Jing Hu,Yi Fang,Jun Wang,Yu Cao,Wenrui Liu,Lianxiang Duan 한국식품영양과학회 2024 Journal of medicinal food Vol.27 No.1
Theaflavins are the characteristic polyphenols in black tea which can be enzymatically synthesized. In thisreview, the effects and molecular mechanisms of theaflavins on obesity and its comorbidities, including dyslipidemia, insulinresistance, hepatic steatosis, and atherosclerosis, were summarized. Theaflavins ameliorate obesity potentially via reducingfood intake, inhibiting pancreatic lipase to reduce lipid absorption, activating the adenosine monophosphate-activated proteinkinase (AMPK), and regulating the gut microbiota. As to the comorbidities, theaflavins ameliorate hypercholesterolemia byinhibiting micelle formation to reduce cholesterol absorption. Theaflavins improve insulin sensitivity by increasing thesignaling of protein kinase B, eliminating glucose toxicity, and inhibiting inflammation. Theaflavins ameliorate hepaticsteatosis via activating AMPK. Theaflavins reduce atherosclerosis by upregulating nuclear factor erythropoietin-2-relatedfactor 2 signaling and inhibiting plasminogen activator inhibitor 1. In randomized controlled trails, black tea extractscontaining theaflavins reduced body weight in overweight people and improved glucose tolerance in healthy adults. Theamelioration on the hyperlipidemia and the prevention of coronary artery disease by black tea extracts were supportedby meta-analysis.

A cytoplasmic male sterile line (designated as M2BS) was obtained from an indica rice maintainer M2B induced by partial-length HcPDIL5-2a (Hibiscus cannabinus protein disulfide isomerase-like) transformation. The anther of M2BS was short, slender, hygrophanous, and fissured. I2-KI staining method showed that there was typical and spherical abortion in pollen grains. M2BS was found abortive at middle and late stage of monocyte by the modified carbol fuchsin stained observation and paraffin section observation. The tapetum was observed pre-degenerated in M2BS. Hereditary analysis indicated that the male sterility of M2BS was a maternally inherited inability after six backcross generations with M2B and the combinations of M2BS hybridized with other two male fertile materials. The M2BS could be affirmed a cytoplasmic male sterile (CMS) type. Moreover, it was a transgenic plant confirmed by PCR, Southern blot and RT-PCR detection. M2BS could be distinguished from M2B and its CMS line M2A by RFLP analysis. The overall mitochondrial genome sequencing results showed, that in M2BS, the main differences of mitochondrial gene sequence were located in nad4, nad5, nad7, orf194 and intergenic region, relatively to those of M2A. The obtained results indicate that M2BS is a novel cytoplasmic male sterile line.

<P>In order to understand the initial conditions and early evolution of star formation in a wide range of Galactic environments, we carried out an investigation of 64 Planck Galactic cold clumps (PGCCs) in the second quadrant of the Milky Way. Using the (CO)-C-13 and (CO)-O-18 J = 1-0 lines and 850 mu m continuum observations, we investigated cloud fragmentation and evolution associated with star formation. We extracted 468 clumps and 117 cores from the (CO)-C-13 line and 850 mu m continuum maps, respectively. We made use of the Bayesian distance calculator and derived the distances of all 64 PGCCs. We found that in general, the mass-size plane follows a relation of m similar to r(1.67). At a given scale, the masses of our objects are around 1/10 of that of typical Galactic massive star-forming regions. Analysis of the clump and core masses, virial parameters, densities, and mass-size relation suggests that the PGCCs in our sample have a low core formation efficiency (similar to 3.0%), and most PGCCs are likely low-mass star-forming candidates. Statistical study indicates that the 850 mu m cores are more turbulent, more optically thick, and denser than the (CO)-C-13 clumps for star formation candidates, suggesting that the 850 mu m cores are likely more appropriate future star formation candidates than the (CO)-C-13 clumps.</P>
