The objective of this study was to observe the acute cytotoxic effects of hematoporphyrin monomethyl ether sonodynamic therapy (HMME-SDT) on hypertrophic scar fibroblasts of rabbit ears. We first assessed the effects of different irradiation times and HMME concentrations on the survival of hypertrophic scar fibroblasts using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)...

B-cell receptor-associated protein 31 (BAP31) is an endoplasmic reticulum (ER) membrane protein which plays a role as a molecular chaperone for the newly synthesized transmembrane proteins. BAP31 is also an important apoptosis regulator for extrinsic apoptosis induction in the ER membrane. Recent studies have shown that BAP31 is also expressed on the surface of embryonic stem cells. However, th...

umbilical cord blood (ucb) has been used for transplantation in the treatment of hematologic disorders as a source of hematopoietic stem cells (hscs). because of insufficient number of cord blood cd34+ cells, the expansion of these cells seems to be important for clinical application. mesenchymal stromal cells (mscs), playing an important role in hscs maintenance, were used as feeder layer. apo...

background: alzheimer’s disease (ad) is a progressive neurodegenerative disease and nowadays the role of endothelial cell (ec) injury has been proposed in pathological process in ad. peroxisome proliferator‑activated receptor‑γ (ppar‑γ) agonist has anti‑inflammatory properties through activation in glial cells and improves vascular function and prevent atherosclerotic disease progression. the a...

(ABSTRACT) Recent studies suggest that lymphocyte apoptosis serves to regulate pulmonary inflammation. Equine COPD, an allergic disease of the lower airway, is likely due to dysregulation of the pulmonary immune response. In this study, the hypothesis tested was COPD affected horses would have less apoptotic airway lymphocytes than control horses during clinical disease. To achieve this, 3 meth...

the purpose of the present study is to investigate the cytotoxicity/apoptotic effect of 2-chloro-2′-deoxyadenosine, cladribine, (2-cda) in the human breast cancer cell line, mda-mb468 (estrogen receptor negative, er−). mtt [3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2h tetrazolium bromide] assay, annexin v-fluorescein/pi and hoechst 33258 staining were used to detect cytotoxicity and cell apopto...

Precisely identifying the type of programmed cell death is one of the key questions in contemporary biomedical research. We developed a straightforward approach allowing quantitative discrimination between two types of cell death on the single cell level: apoptosis and necroptosis. This method uses the combination of imaging flow cytometry with classical Annexin V/propidium iodide staining, whi...

Ovarian cancer has the highest mortality rate among gynecological cancers; the most effective therapy for this cancer is a combination of radiation treatment and chemotherapy. However, radiation resistance is the leading factor associated with treatment failure. The present study aimed to investigate pseudolaric acid B (PAB) as a potential radiosensitizer for the treatment of ovarian cancer. Th...

BACKGROUND Although inhibitors of the proto-oncogene BRAF have shown excellent antitumor activity against malignant melanoma, their efficacy is limited by the development of acquired drug resistance, a process in which reactivation of MAP kinase (MEK) is known to play an important role. In this study, we evaluated the efficacy of AS703026, a new MEK inhibitor, in BRAF inhibitor-resistant melano...
