The present investigation was conducted to study the effect of thymic peptide: thymosinalpha1 (thyalpha1) on the activation of tumor associated mphi (TAM) obtained from mice bearing a transplantable T cell lymphoma of spontaneous origin designated as…
The shutter expression vector pPREUT was constructed from the plasmid pPRS-1 containing the endogenous small plasmid of Plectonema boryanum. The expression elements such as heat shock gene groESL promoter, foreign gene Ub-thymosin alpha 1, rbcS polyA…
Hepatitis B e antibody (HbeAb) and hepatitis B virus (HBV) DNA positive chronic hepatitis is a clinical entity, distinct from classical hepatitis B e antigen (HbeAg) positive chronic hepatitis B. Our aim was to evaluate the long-term therapeutic effi…
The studies on thymosins were initiated in 1965, when the group of A. White searched for thymic factors responsible for the physiological functions of thymus. To restore thymic functions in thymic-deprived or immunodeprived animals, as well as in hum…
Cellular immunodeficiency is associated with human cancer. Extensive reviews on cancer of the head and neck, lung, esophagus and breast convince the author that for these diseases the immunodeficiency is reasonably well established yet the mechanisms…
Multiple therapeutic approaches have been tested in different experimental tumour models and in human cancers. Most part of them are based on the hypothesis that the inhibition of tumour growth requires a strong immune response in which a main role i…
Treatment of chronic hepatitis B and C viruses (HBV and HCV) is still disappointing, and both are the major causes of liver cirrhosis and hepatocarcinoma. Interferon and lamivudine are the registered drugs for chronic HBV but are scarcely effective o…
Chronic hepatitis B virus (HBV) infection, which can lead to cirrhosis and hepatocellular carcinoma, is a major health threat worldwide. Classic patients with chronic hepatitis B are positive for hepatitis Be-antigen (HBeAg) and HBV-DNA. In the Medit…
OBJECTIVE: To investigate the effect of thymosin alpha 1 on cellular immune function in the elderly patients with malignant tumor. METHODS: Thirty patients with malignant tumor were injected with thymosin alpha 1 subcutaneously at the dose of 1.6 mg…
OBJECTIVE: To assess the co-morbidity of anxiety and depression in hospitalized patients and to analyze the degree of symptoms and the influential factors. METHODS: Thirty patients with malignant tumor were injected with thymosin alpha 1 subcutaneous…
Thymosin alpha-1 (Talpha1) not only possesses immunoregulatory properties in periphery but also is expressed in the central nervous system (CNS) and affects the function of the CNS. To further elucidate the role of Talpha1 in the CNS, the whole-cell…
OBJECTIVE: The efficacy of thymosin alpha 1 (Talpha1) in patients with chronic hepatitis B still requires confirmation. We, therefore, evaluated the efficacy of therapy in patients with chronic hepatitis B. METHODS: Sixteen patients were randomly ass…
Current therapeutic options for hepatitis C are limited, especially for genotype 1. For genotypes 2 and 3, pegylated interferon in combination with ribavirin, can lead to a sustained virological response in up to 80% of patients. Unfortunately, adver…
To study the safety and efficacy of thymosin alpha1 in stimulating immune reconstitution in combination with highly active antiretroviral therapy (HAART), a phase II randomized, controlled open-label trial of subcutaneous thymosin alpha1 was undertak…
Pituitary cells from six pigs, 180-200 days of age, were studied in primary culture to determine if growth hormone releasing factor (GRF) affects long form leptin receptor (Ob-Rl) expression. On Day 4 of culture, 10(5) live cells per well were challe…
Ghrelin, a circulating growth-hormone releasing peptide derived from stomach, stimulates food intake through neuropeptide Y (NPY) neurons of the arcuate nucleus in the hypothalamus (ARC). We examined the effect of ghrelin microinjected into the ARC a…
Angiogenesis plays a key role in solid tumor formation, invasiveness and metastasis. Vascular endothelial growth factor (VEGF) is an endothelial cell-specific mitogen that is necessary in the process of neovascularisation. Antagonists of growth hormo…
We report the development of a sensitive, and specific, competitive, antigen-capture enzyme-linked immunosorbent assay for the measurement of channel catfish (Ictalurus punctatus) growth hormone (cfGH). The detection limit of the assay (90% binding)…
Synthetically produced GRF1-29 (Sermorelin) has an amino acid composition identical to the N-terminal 29 amino acids sequence of the natural hypothalamic GHRH1-44 (Figure 1). It maintains bioactivity in vitro and is almost equally effective in elicit…
Vertebrate growth is principally controlled by growth hormone (GH) and, its intermediary, insulin-like growth factor-I (IGF-I). The actions of IGF-I are modulated by high-affinity binding proteins called insulin-like growth factor binding-proteins (I…
