The treatment of neurocysticercosis (NCC) varies with location, number and stage of the Taenia solium cysticerci (cysts). Albendazole (ABZ) effectively kills cysticerci, and subsequently induces neuro-inflammation facilitated by leukocyte infiltration. We hypothesize that immune response varies around drug responder (degenerating/dying) and non-responder (viable) cysts after ABZ and ABZ plus steroid (ABZS) therapy, which may determine the disease pathogenesis. Twenty cysticercotic swine were treated with ABZ (n = 10; group1) and ABZS (n = 10; group2)...

Fecal contamination of drinking water is associated with large hepatitis E virus (HEV) outbreaks of genotypes 1 and 2 in endemic areas. Sporadic transmission of HEV genotypes 3 and 4 in high-income countries has been associated with exposure to blood and animal contact. The objective of the study was to identify the risk factors for hepatitis E and the genotype(s) causing sporadic hepatitis E in Dhaka, Bangladesh. We selected, from a diagnostic center in Dhaka between November 2008 and November 2009, cases presenting with jaundice and anti-HEV IgM antibodies and age-matched controls were defined as those with no history of jaundice and normal blood test results...

Objective: Exosomes are nanovesicles that are released from normal and tumor cells and are detectable in cell culture supernatant and human biological fluids. Although previous studies have explored exosomes released from cancer cells, little is understood regarding the functions of exosomes released by normal cells. Natural killer (NK) cells display rapid immunity to metastatic or hematological malignancies, and efforts have been undertaken to clinically exploit the antitumor properties of NK cells. However, the characteristics and functions of exosomes derived from NK cells remain unknown...

Cardiac progenitor cells have a limited proliferative capacity. The CREB-binding protein/p300-interacting transactivator, with the Glu/Asp-rich carboxy-terminal domain (Cited) gene family, regulates gene transcription. Increased expression of the Cited4 gene in an adult mouse is associated with exercise-induced cardiomyocyte hypertrophy and proliferation. However, the expression patterns and functional roles of the Cited4 gene during cardiogenesis are largely unknown. Therefore, in the present study, we investigated the expression patterns and functional roles of the Cited4 gene during in vitro cardiogenesis...

BACKGROUND: Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-β (TGF-β) superfamily. Recently, BMP7 has been demonstrated to be produced by salivary glands and contribute to embryonic branching in mice. The BMP7 in saliva is thought to be delivered to the oral cavity and is expected to contact with stratified squamous epithelial cells which line the surface of oral mucosa. In this study, we attempted to investigate the effects of BMP7 on oral epithelial cells...

OBJECTIVE: The aim of this study was to assess the impact of chemoradiation on the immune microenvironment to influence and optimally design future neoadjuvant clinical trials. SUMMARY BACKGROUND DATA: Programmed death (PD)-1 inhibitors in metastatic gastroesophageal cancer have demonstrated response rates of approximately 25% in programmed death ligand-1 (PD-L1+) tumors. Unfortunately, the majority of patients do not respond. Therefore, a rationale strategy of combining immunotherapeutic agents with chemoradiation in earlier stage esophageal cancer may prevent metastatic disease in patients...

Cartilage tissue engineering provides a new method in the treatment of cartilage defects, and adipose derived stem cells seem to be an ideal seed cell in cartilage tissue engineering because of its characteristics. However, ossification after in vivo implantation of tissue engineered cartilage remains a challenge. Thrombospondin-1 which has been reported to have an inhibitory effect on angiogenesis, may play an important role in inhibiting the ossification of tissue engineered cartilage constructed by adipose derived stem cells...

Micro-ribonucleic acids (miRNAs) are small functional non-coding RNAs that downregulate gene expression at the post-transcriptional level. Abnormal expression of specific miRNAs has been recorded in chronic lymphocytic leukaemia, other non-Hodgkin B-cell lymphomas, lung cancer and chronic myeloid leukaemia (CML). The aim of this study was to compare miRNA expression profiles among patients with newly diagnosed CML, those on established therapy with imatinib mesylate, and healthy individuals. The expression of 88 miRNAs was evaluated in a total of nine samples divided into three groups: Group 1 comprised three samples collected from newly diagnosed CML patients; group 2 consisted of three samples collected from patients on therapy; the remaining three samples were collected from healthy volunteers (control group)...
