The plant milk market has a promising future and flavor is a critical quality attribute of plant milk. The good flavors of plant milk such as milky, fruity, nutty, and cereal-like aromas are well-liked by consumers, while the undesirable flavors such as bitterness, bean-like odor, green odor, and mushroom-like odor severely limit the development of the plant milk industry. Based on the current state of development and future trends in raw material screening and processing technology for plant milk production and research on the flavor composition of plant milk, this paper summarizes the methods used for the extraction and identification of volatile substances from plant milk and the material basis of its flavor composition, highlighting the formation pathways of aroma and off-odor, the interaction between macromolecules and small molecules in plant milk, and the influential factors of and the regulatory strategies for the formation of aroma and off-odor in plant milk. This review is expected to provide scientific research ideas and strategies for maximizing the preservation of the good flavor of plant milk and avoiding the generation of undesirable flavors.

Plaque vulnerability has been the subject of several recent studies aimed at reducing the risk of stroke and carotid artery stenosis. Atherosclerotic plaque development is a complex process involving inflammation mediated by macrophages. Plaques become more vulnerable when the equilibrium between macrophage recruitment and clearance is disturbed. Lipoperoxides, which are affected by iron levels in cells, are responsible for the cell death seen in ferroptosis. Ferroptosis results from lipoperoxide-induced mitochondrial membrane toxicity. Atherosclerosis in ApoE(−/−) mice is reduced when ferroptosis is inhibited and iron intake is limited. Single-cell sequencing revealed that a ferroptosis-related gene was substantially expressed in atherosclerosis-modeled macrophages. Since ferroptosis can be regulated, it offers hope as a non-invasive method of treating carotid plaque. In this study, we discuss the role of ferroptosis in atherosclerotic plaque vulnerability, including its mechanism, regulation, and potential future research directions.

Chronic intestinal pseudo-obstruction (CIPO) is a rare intestinal motility disorder with significant morbidity and mortality in pediatric patients. The diagnosis of CIPO is difficult, because it is clinically based on the symptoms and signs of bowel obstruction which are similar to the clinical manifestations of other gastrointestinal diseases like short bowel syndrome (SBS). Therefore, it is desirable to identify and establish new laboratory diagnostic markers for CIPO that are reliable and easily accessible. In our study we have identified the ratio of the urinary glutamine and glutamic acid as a promising biomarker for distinguishing suspected CIPO cases and simple SBS cases. The area under ROC curve was 0.83, at cutoff value = 7.04 with sensitivity of 65% and specificity of 92%. [ABSTRACT FROM AUTHOR]

This study established the EA.hy926 cell myocardial ischemia model to compare the effects of two Kaixin Powder prescriptions, Buxin Decoction(BXD) and Dingzhi Pills(DZP), at three dosages(500, 200, and 100 μg·mL~(-1)) on the cell viability. Further, the public databases(TCMSP, TCMID, SYMMAP, and STRING) and the network pharmacology methods such as KEGG pathway enrichment were employed to decipher the possible molecular mechanism of BXD in exerting the cardioprotective effect. The pharmacological effect of BXD was evaluated with the rat model of isoprenaline(ISO)-induced myocardial ischemia. The expression levels of proteins involved in the phosphatidylinositol-3-kinase/protein kinase B(PI3 K/AKT) signaling pathway were measured by Western blot. BXD significantly increased the viability of EA.hy926 cells, showing the performance superior to DZP. The network pharmacology analysis predicted that BXD might exert cardiac protection through the PI3 K/AKT signaling pathway. The in vivo experiment on rats showed that BXD treatment significantly increased the cardiac ejection fraction(EF), fractional shortening(FS), diastolic left ventricular anterior wall(LVAWd), systolic left ventricular anterior wall(LVAWs), and diastolic left ventricular posterior wall(LVPWd), significantly decreased the beat per minute(BPM) and diastolic left ventricular internal diameter(LVIDd), and significantly improved the ST segment in the electrocardiogram. The pathological results(Masson staining) showed that BXD restored the myocardial thickness, decreased the collagen fiber, increased the muscle fiber, and reduced the infarct area to alleviate myocardial ischemia. Furthermore, BXD lowered the serum levels of inflammatory cytokines [tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6)] and myocardial enzymes [creatine kinase(CK) and lactate dehydrogenase(LDH)], increased the p-AKT/AKT ratio, up-regulated the protein levels of PI3 K, NF-κB, IKK-α, and Bcl-xl, and down-regulated that of the apoptotic protein Bax. In conclusion, BXD may exert cardiac protection effect by regulating the PI3 K/AKT signaling pathway.

Aim: To obtain reference values for pancreatic flow output rate (PFR) and peak time (PT) in healthy volunteers and chronic pancreatitis (CP); to correlate quantification of secretin enhanced magnetic resonance cholangiopancreatography (SMRCP) of pancreatic fluid output following secretin with fecal elastase-1 (FE-1) tests., Methods: The present study includes 53 subjects comprised of 17 healthy individuals and 36 patients with CP from April 2011 to January 2013. The 36 patients with CP were divided into three groups of mild CP (n = 14), moderate CP (n = 19) and advanced CP (n = 3) by M-ANNHEIM classification for CP.. Fifty-three cases underwent FE-1 test and magnetic resonance imaging using 3.0 T-device (Signa EXCITE, GE Healthcare). Coronal T2-weighted single-shot turbo spin-echo, spiratory triggered, covering the papillae, duodenum and small bowel. MRCP was performed with a heavily T2-weighted fat-suppressed long TE HASTE sequence (thick slab 2D MRCP sequence), repeated every 2 min up to 11 min after 0.1 mL/kg secretin injection (Secrelux, Sanochemia(®), Germany). FE-1 test used sandwich enzyme-linked immunosorbent assay (ELISA) test (ScheBo. Tech(®), Germany)., Results: A good linear correlation showed between the calculated volume and the actual volume by Phantom experiments. Fifty-three paired Quantification of secretin enhanced magnetic resonance cholangiopancreatography (MRCPQ) and FE-1 data sets were analyzed. The mean FE-1 of 53 cases was 525.41 ± 94.44 μg/g for 17 healthy volunteers, 464.95 ± 136.13 μg/g for mild CP, 301.55 ± 181.55 μg/g for moderate CP, 229.30 ± 146.60 μg/g for advanced CP. Also, there was statistically significant difference in FE-1 (P = 0.0001) between health and CP. The mean values of PFR and PT were 8.18 ± 1.11 mL/min, 5.76 ± 1.71 min for normal; 7.27 ± 2.04 mL/min, 7.71 ± 2.55 min for mild CP; 4.98 ± 2.57 mL/min, 9.10 ± 3.00 min for moderate CP; 4.13 ± 1.83 mL/min, 12.33 ± 1.55 min for advanced CP. Further, statistically significant difference in PFR (P = 0.0001) and PT (P = 0.0001) was observed between health and CP. Besides, there was correlation (r = 0.79) and consistency (K = 0.6) between MRCPQ and ELISA Test. It was related between M-ANNHEIM classification and PFR (r = 0.55), FE-1 (r = 0.57)., Conclusion: SMRCP can provide a safe, non-invasive and efficient method to evaluate the exocrine function of the pancreas.
