Afferent Renal Denervation Attenuates Sympathetic Overactivation From the Paraventricular Nucleus in Spontaneously Hypertensive Rats.

Background: The effectiveness of renal denervation (RDN) in reducing blood pressure and systemic sympathetic activity in hypertensive patients has been established. However, the underlying central mechanism remains unknown. This study aimed to investigate the role of RDN in regulating cardiovascular function via the central renin-angiotensin system (RAS) pathway.

Effective-component compatibility of Bufei Yishen formula III ameliorated COPD by improving airway epithelial cell senescence by promoting mitophagy via the NRF2/PINK1 pathway.

Background: Effective-component compatibility of Bufei Yishen formula III (ECC-BYF III) demonstrates positive effects on stable chronic obstructive pulmonary disease (COPD).

Purpose: To investigate the mechanisms of ECC-BYF III on COPD rats from the aspect of airway epithelial cell senescence.

Methods: COPD model rats (Sprague-Dawley rat) were treated with ECC-BYF III for 8 weeks, and the efficacy was evaluated.

Effect of Exercise Prescription Implementation Rate on Cardiovascular Events.

Background: Exercise prescription of cardiac rehabilitation (CR) is vital in patients with cardiovascular diseases (CVDs) and those carrying high risk for CVDs. However, the relation between the implementation rate of exercise prescription and cardiovascular events (CVEs) is unclear.

Design And Methods: In this retrospective study, using the administration data from the Rehabilitation Center in a hospital, patients aged ≥18 years with CVDs were consecutively enrolled from November 2018 to May 2021.

Ligand-Promoted Rh -Catalyzed Thiolation of Benzamides with a Broad Disulfide Scope.

A ligand-promoted Rh -catalyzed C(sp )-H activation/thiolation of benzamides has been developed. Using bidentate mono-N-protected amino acid ligands led to the first example of Rh -catalyzed aryl thiolation reactions directed by weakly coordinating directing amide groups. The reaction tolerates a broad range of amides and disulfide reagents.

Supramolecular system of podophyllotoxin and hydroxypropyl-β-cyclodextrin: Characterization, inclusion mode, docking calculation, solubilization, stability and cytotoxic activity.

The inclusion complexation behavior, characterization, and inclusion mode of podophyllotoxin (POD) with hydroxypropyl-β-cyclodextrin (HPβCD) were investigated in both solution and the solid state by means of XRD, DSC, SEM, H and 2D NMR and UV-vis spectroscopy. The results showed that the water solubility and thermal stability of POD were obviously increased in the inclusion complex with HPβCD. The cytotoxicity of POD/HPβCD inclusion complex against all the human tumor cell lines investigated still remains.

Synthesis and cytotoxic activity of novel tetrahydrobenzodifuran-imidazolium salt derivatives.

The synthesis of a series of novel 4-substituted 2,3,6,7-tetrahydrobenzo [1,2-b;4,5-b']difuran-1H-imidazolium salts is presented. The biological properties of the compounds were evaluated in vitro against a panel of human tumor cell lines. Results suggest that the 5,6-dimethyl-benzimidazole or 2-methyl-benzimidazole ring, and substitution of the imidazolyl-3-position with a 2-naphthylmethyl substituent or 2-naphthylacyl substituent, were important to the cytotoxic activity.

Synthesis and antitumor activity of novel N-substituted tetrahydro-β-carboline-imidazolium salt derivatives.

The synthesis of a series of novel N-substituted tetrahydro-β-carboline-imidazolium salt derivatives is presented. The biological properties of the compounds were evaluated in vitro against a panel of human tumor cell lines. The results suggest that the benzimidazole ring and 1-(naphthalen-2-yl)ethan-1-one or 2-naphthylmethyl substituent at the imidazolyl-3-position were vital for modulating cytotoxic activity.

Host-guest system of hesperetin and β-cyclodextrin or its derivatives: Preparation, characterization, inclusion mode, solubilization and stability.

The inclusion complexation behavior, characterization and binding ability of hesperetin with β-cyclodextrin and its derivatives were investigated in both the solution and solid state by means of XRD, DSC, SEM, (1)H and 2D NMR and UV-vis spectroscopy. The results showed that the water solubility and stability of hesperetin were obviously increased in the inclusion complex with cyclodextrins. This satisfactory water solubility and high stability of the hesperetin/CD complexes will be potentially useful for their application as herbal medicines or healthcare products.

[α-GalCer reduces Acute Graft-versus-Host Disease by Altering Donor T Cells Migration].

Objective: This study was aimed to explore the new mechanism of α-Galactosyleramide (α-GalCer), a synthetic glycolipid, and a well-known activator of natural killer T cells (NKT) for improving acute graft-versus-host disease(aGVHD).

Methods: Murine allogeneic bone marrow transplantation (allo-BMT) model was established. Recipient mice were injected intraperitoneally with α-GalCer immediately after allo-BMT, whereas mice from the vehicle groups received the diluent (DMSO) only.
