Probucol has been utilized as a cholesterol-lowering drug with antioxidative properties. However, the impact and fundamental mechanisms of probucol in obesity-related cognitive decline are unclear. In this study, male C57BL/6J mice were allocated to a normal chow diet (NCD) group or a high-fat diet (HFD) group, followed by administration of probucol to half of the mice on the HFD regimen.

Article Synopsis
  • Researchers studied how a diet of cold drinks and high-fat foods affects adult mice.
  • Mice on this diet had diarrhea, felt weak, and showed less healthy gut bacteria compared to those on a normal diet.
  • The study found that this unhealthy diet damages the gut and immune system, which could help in making new medicines or healthier foods.

Sub-health status, in which a person's mind and body exist in a low-quality state of being between disease and health, has become an urgent public health problem that cannot be ignored globally. One of the most apparent sub-health symptoms is fatigue, and it also shows a significant decrease in mental vitality and adaptability caused by disruption of the neuroendocrine-immune system. (DOF) has a long history of use in China as a medicinal food with immune-regulating, anti-fatigue, anti-oxidant, and hypoglycemic effects.

A green smashing tissue and ultrasonic (STU) extraction method, which combines smashing tissue and ultrasonic-assisted extraction, was developed for the first time. The extraction of tanshinones from Bunge (SM) was taken as an example to discuss the practicability of this method. Taking the total yield of eight tanshinones as an evaluation index, response surface methodology (RSM) and artificial neural network (ANN) models were used to optimize the extraction parameters, and these two models were also compared by investigating the extract yield of tanshinones and the antioxidant activity of the obtained SM extract.

Objectives: Epigallocatechin gallate (EGCG) is the main bioactive component of polyphenols in tea, which has a variety of biological effects. The neurologic injury caused by cerebral ischemia/reperfusion (I/R) is closely related to the inflammatory reaction. The pro-inflammatory factor interleukin-1β (IL-1β) and the anti-inflammatory factor interleukin-10 (IL-10) play important roles in the regulation of inflammatory reaction.

Introduction: Pancreatic cancer remains one of the most lethal malignancies and has few treatment options. Saikosaponin D (SSD), a major bioactive triterpene saponin isolated from , has been reported to exert cytotoxicity properties toward many cancer cells. However, the effects of SSD on pancreatic cancer have been little scrutinized.

To investigate the antipyretic effect of active components of Mahuang Decoction in febrile rats, and explore its correlation with pharmacokinetics at different time points. The feverished rat models were induced by dry yeast, and intragastrically administered with the effective components of Mahuang Decoction with different orthogonal compatibility ratios. At different time points after administration, body temperature was measured; blood was taken from orbital vena plexus, and the contents of interleukin-6(IL-6), interleukin-1β(IL-1β), and tumor necrosis factor-α(TNF-α) in rat serum were determined with the kits.

Chalcones is a flavonoid wildly presented in many herbs. It has the effect to inhibit cells adipogenic differentiation. In order to study the effect of pinostrobin chalcone extracted and isolated from leaves of hickoryes on the adipogenic differentiation of murine embryonic mesenchymal stem cell (C3H10T1/2), MTS [3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)- 2H-tetrazolium] method was used to detect the cell proliferation; adipogenic differentiation was characterized by oil red O staining and isopropanol extraction; the triglyceride content was detected by GAP-PAP enzyme method; and the C3H10T1/2 cell differentiation into adipocytes was also examined by the mRNA and protein expression of PPARγ, C/EBPα and FABP4 by RT-PCR and Western blot respectively.

Background And Objectives: Ephedra alkaloids, including ephedrine (EP), pseudoephedrine (PEP) and methylephedrine (MEP), are sympathomimetic compounds with known toxicities but many Ephedra (Ephedrae herba) preparations, such as Ephedra decoction, have been clinically applied for centuries. In order to explore the possible detoxification mechanism of Ephedra alkaloids, four representative compounds in Ephedra decoction (cinnamic acid, amygdalin, glycyrrhizic acid and liquiritin) were studied for their pharmacokinetic effects on Ephedra alkaloids in Sprague-Dawley rats.

Methods: Animals were randomly divided into six groups, with six rats in each.

Objective: To establish HPLC fingerprint of HQSM capsules,and a new method for correlativity analysis between fingerprint peaks of HQSM and its relevant herbs based on the fingerprint analysis.

Method: The chromatographic fingerprints of HQSM and its relevant herbs were analyzed by HPLC configured with DAD. The similarity of the HPLC fingerprints between HQSM and its relevant herbs and the comparison of UV spectra of the main peaks in both of fingerprints were used as indices to evaluate the correlativity.

A navigation process is studied on a variant of the Watts-Strogatz small-world network model embedded on a square lattice. With probability , each vertex sends out a long-range link, and the probability of the other end of this link falling on a vertex at lattice distance away decays as r(-a). Vertices on the network have knowledge of only their nearest neighbors.
