In the design of highly ordered (covalent organic frameworks) COFs with "ordered domains size and orientation" construction in a well-defined arrangement, the molecular monomers are the key factors. Here, the effect of molecular monomers on the construction of COFs has been studied, and two kinds of molecular monomers, i.e.

Histone deacetylases (HDACs) inhibitors are novel in cancer therapy nowadays. HDAC6-selective inhibitors exert advantageous effects due to higher selectivity and less toxicity. We explored the anti-tumor effect and the molecular mechanism of cay10603, a potent HDAC6 inhibitor in Burkitt's lymphoma cells.

Previous studies have indicated that gut-derived endotoxin played a pivotal role for aggravating systemic inflammatory response to multi-organ dysfunction under heatstroke. Dexmedetomidine (DEX) could protect against inflammation and multi-organ injury in various scenarios. The aim of this study was to explore the protective effect of DEX on heatstroke and the mechanism involved.

Herein, two Wells -Dawson-type arsenomolybdates, formulated as [Cu(pyr)][AsMoO] (1) and [Ag(pyr)][AsMoO] (2) (pyr = pyrazole), were hydrothermally synthesized and structurally characterized via single-crystal X-ray diffraction, elemental analysis, IR and UV-vis-NIR spectroscopies, XPS, XRD, and TG analysis. The structural analysis indicated that compounds 1 and 2 were isomorphic. They are the first reported 3D honeycomb structures of Wells-Dawson-type arsenomolybdates.

A limit to the clinical benefit of radiotherapy is not an incapacity to eliminate tumor cells but rather a limit on its capacity to do so without destroying normal tissue and inducing inflammation. Recent evidence reveals that the inflammasome is essential for mediating radiation-induced cell and tissue damage. In this study, using primary cultured bone marrow-derived macrophages (BMDM) and a mouse radiation model, we explored the role of NLRP3 inflammasome activation and the secondary pyroptosis underlying radiation-induced immune cell death.

Article Synopsis
  • The NLRP3 inflammasome is a protein complex in the immune system that helps with sensing infections and is linked to feelings of fatigue.
  • Scientists created a mouse model to study fatigue using a chemical called LPS and a swim stress test to see how NLRP3 affects this feeling.
  • They found that mice with active NLRP3 showed less activity and more fatigue symptoms, while mice without NLRP3 were more active and had less fatigue.

Many studies have reported the association between the CARD8 gene polymorphism rs2043211 and the susceptibility to Crohn's disease (CD), but the results have remained quite contradictory. Therefore, the aim of the meta-analysis was to explore whether the CARD8 rs2043211 polymorphism has an effect on CD risk. We performed a systematic literature search for related articles published up to July 2014 in multiple databases.

A quarterly investigation of the macrozoobenthos community in Tian'e Zhou Yangtze Oxbows was conducted during January 2011 to October 2011. And water quality was assessed based on the benthic macroinvertebrate community structure. It shows that, a total of 30 macrozoobenthos species were found, among which, Insecta (14 species) , Mollusca (6 species), Oligochaeta (8 species) and others (2 species) accounted for 46.

Previous studies have reported an association between vitamin D receptor (VDR) gene polymorphisms and Parkinson's disease (PD), but the results were controversial. To explore whether VDR gene polymorphisms have an effect on PD risk, we performed this meta-analysis to evaluate the association between three VDR gene polymorphisms (Bsml, Apal, Taql) and PD susceptibility. We performed a systematic literature search for articles published up to February 2014 in multiple databases and selected seven eligible studies.

Aims: To determine whether E-selectin deficiency can attenuate brain ischemia in a mouse model of focal cerebral ischemia.

Methods: E-selectin was determined in spontaneously hypertensive rats (SHRs) and stroke-prone spontaneously hypertensive rats (SHR-SPs). E-selectin knockout (Es(-/-) ) mice and wild-type control (WT) mice underwent permanent distal middle cerebral artery occlusion (MCAO).

Aim: This study was designed to investigate the effects of telmisartan and amlodipine on reduction of blood pressure (BP), myocardial hypertrophy, and renal injury in hypertensive rats.

Method: In acute experiments, the BP was measured in conscious freely moving rats. Spontaneously hypertensive rats were treated with intragastric administration of amlodipine (1, 2, 4 mg/kg), telmisartan (4, 8, 12, 16, 20 mg/kg), and their different combinations (4 + 4, 2 + 4, 4 + 8, 4 + 12, 1 + 4, 2 + 8, 4 + 16, 2 + 12, 1 + 8, 2 + 16, 2 + 20, 1 + 12, 1 + 16, 1 + 20 mg/kg).

Article Synopsis
  • Inflammation plays a significant role in causing and worsening end-organ damage (EOD) in individuals with hypertension, with recent findings highlighting the α7 nicotinic acetylcholine receptor (α7nAChR) as a key player in this process.
  • Studies on spontaneously hypertensive rats and rats with induced hypertension showed that a lack of proper α7nAChR function resulted in reduced expression of related proteins and inflammation in cardiovascular tissues.
  • Administering an α7nAChR agonist was effective in reducing EOD and associated inflammation, suggesting that addressing dysfunction in this pathway could be a potential strategy for treating hypertension-related cardiovascular issues.

Aim: To reinvestigate the characteristics of reserpine-induced gastric mucosal lesions (GMLs).

Methods: The GML-inducing effect of reserpine and the time-course of recovery from reserpine-induced GMLs were examined in Sprague-Dawley (SD) rats. The GML-inducing and blood pressure-decreasing effects of Compound Hypotensive Tablets (CHTs) were investigated in spontaneously hypertensive rats (SHRs).

Blood pressure reduction is an important and effective strategy in stroke prevention in hypertensives. Recently, we found that baroreflex restoration was also crucial in stroke prevention. The present work was designed to test the hypothesis that a combination of blood pressure reduction and baroreflex restoration may be a new strategy for stroke prevention.

Background And Purpose: Angiotensin receptor blockers are widely used in patients at high risk of cardiocerebrovascular events. The aim of this meta-analysis was to investigate the effects of angiotensin receptor blockers on the risk of stroke.

Methods: Electronic searches of MEDLINE, EMBASE, and the Cochrane central register of controlled trials were performed.

Aim: To investigate the effects of allisartan, a new angiotensin II type 1 (AT(1)) receptor antagonist, on blood pressure (BP) and end-organ damage (EOD) in hypertensive rats and dogs.

Methods: First, a single dose of allisartan was given intragastrically to evaluate the BP reduction in spontaneously hypertensive rats (SHRs), two kidney-one clip (2K1C) renovascular hypertensive rats and dogs, and Beagle dogs with angiotensin II-induced hypertension. Second, allisartan was mixed in rat chow for long-term treatment.

Aim: To investigate the effect of clonidine, moxonidine, folic acid, and mecobalamin on arterial baroreflex (ABR) function in stroke-prone spontaneously hypertensive rats (SHR-SP) and the possible mechanisms involved.

Methods: Eighty-one SHR-SP were divided into 7 groups. Four groups were designated for the intragastric (ig) administration of clonidine (1.

Article Synopsis
  • - The study explores the role of baroreflex sensitivity (BRS) in predicting and preventing strokes in hypertensive rats, proposing that higher BRS may delay stroke occurrence.
  • - Researchers used various groups of stroke-prone rats to measure the effects of the drug ketanserin on blood pressure and BRS, finding that higher doses of the drug significantly lowered blood pressure and improved BRS.
  • - Results showed that rats with higher BRS had a longer survival time and that both doses of ketanserin reduced the incidence of fatal strokes, suggesting that restoring BRS could be a viable strategy for stroke prevention in hypertension.
