Vein graft remains the most broadly applied vascular material in coronary artery bypass surgery. However, the restenosis rate of the vein bridge following angioplasty is high. The present study investigated the effect of medical adhesive on vascular intimal hyperplasia, in addition to the signal transduction mechanism. A total of 36 New Zealand white rabbits were divided into three groups at random, including the normal group, the surgery group and the medical adhesive spray group. Following surgery for transplantation of the left external jugular vein to the ipsilateral common carotid artery for 4 weeks, the thickness and area of the intima and media of the vessel were measured on formalin‑fixed, paraffin wax‑embedded pathological sections using hematoxylin‑eosin staining, and alterations in the expression of proliferating cell nuclear antigen (PCNA), platelet endothelial cell adhesion molecule 1 (PECAM‑1), vascular cell adhesion protein 1 (VCAM‑1), extracellular signal‑regulated kinase (ERK)1/2, and endothelial nitric oxide synthase (eNOS) were detected by immunohistochemical staining, reverse transcription‑quantitative polymerase chain reaction analysis and western blotting...

Hepatitis B virus (HBV) infection is a global public health problem. T helper (Th)1‑associated cytokines are involved in HBV clearance during acute and persistent infection. In our previous study, it was demonstrated that lentiviral vectors encoding ubiquitinated hepatitis B core antigen (LV‑Ub‑HBcAg) effectively transduced dendritic cells (DCs) to induce maturation, which promoted T cell polarization to Th1 and generated HBcAg‑specific cytotoxic T lymphocytes (CTLs) ex vivo. In the present study, HBV transgenic mice were immunized with LV‑Ub‑HBcAg‑transduced DCs and HBcAg‑specific immune responses were evaluated...

Pristimerin, a quinonemethide triterpenoid, has demonstrated anticancer activity against a number of types of cancer, including breast cancer. However, its mechanism of action remains unclear. The present study investigated the autophagy‑induced anticancer efficacy of pristimerin on MDA‑MB‑231 human breast cancer cells. Pristimerin inhibited the growth of these cells in a concentration‑dependent manner. Treatment with pristimerin dose‑dependently induced an increase of light chain 3B (LC3‑II), whereas autophagy inhibitor 3‑methyladenine (3‑MA) inhibited pristimerin‑induced LC3‑II accumulation and cytotoxic effects...

In umbilical cord blood transplantation (UCBT), the number of cluster of differentiation (CD)34+ cells and colony‑forming units (CFUs) in the cord blood (CB) graft positively correlate with patient survival. Therefore, these parameters are currently used for quality assessment of the cryopreserved CB cells in the attached segment that is considered representative of the CB in the main bag prior to UCBT. Since aldehyde dehydrogenase (ALDH) activity is high in hematopoietic stem cells, the number of ALDH‑bright (ALDHbr) cells was examined in comparison with the number of CD34+ cells and CFUs for the quality assessment of CB units...

Coenzyme A (CoA) is an essential cofactor of cellular metabolism that is involved in ~4% of cellular reactions. Its de novo production relies on five subsequent enzymatic steps, starting with the phosphorylation of vitamin B5. Pantothenate kinase 2 (PANK2) and coenzyme A synthase (COASY) catalyze the first and last steps of this pathway. Mutations in these genes lead to severe and progressive movement disorders, with neurodegeneration and iron accumulation in the basal ganglia, known as PANK2‑ and COASY protein‑associated neurodegeneration, respectively...

Membranous glomerulonephritis (MGN) is one of the most frequent causes of nephrotic syndrome in adults. It is characterized by the thickening of the glomerular basement membrane in the renal tissue. The current diagnosis of MGN is based on renal biopsy and the detection of antibodies to the few podocyte antigens. Due to the limitations of the current diagnostic methods, including invasiveness and the lack of sensitivity of the current biomarkers, there is a requirement to identify more applicable biomarkers...

Aconitum plants, which have analgesic, diuretic and anti‑inflammatory effects, have been widely used to treat various types of disease. However, the apparent toxicity of Aconitum‑derived agents, particularly in the cardiovascular system, has largely limited their clinical use. Thus, the present study investigated whether berberine (Ber), an isoquinoline alkaloid, may reduce myocardial injury induced by aconitine (AC) in rats and the underlying mechanisms. Rats (n=40) were randomly divided into four groups: Control, Chuan‑wu and Chuan‑wu + Ber (8 and 16 mg/kg doses)...

Cardiac hypertrophy is commonly involved in cardiac injury. Oxidative stress can induce cardiac hypertrophy with apoptosis. Potassium bromate (KBrO3) has been widely used as a food additive due to its oxidizing properties. In the present study, the rat‑derived heart cell line H9c2 was used to investigate the effect of KBrO3 on cell size. KBrO3 increased cell size at concentrations <250 µM, in a dose‑dependent manner. Additionally, KBrO3 also promoted the gene expression of two biomarkers of cardiac hypertrophy, brain/B‑type natriuretic peptides (BNP) and β‑Myosin Heavy Chain (β‑MHC)...
