Effects of peptide bioregulators (thymaline, epithalamine, cortexine) on systemic hemodynamics in cardiovascular and cerebrovascular affections were studied. Assessment of functional stability and quality of cardiovascular system regulation was made…
Available clinical data on aspirin-sensitive asthma (ASA) indicate that ASA patients have certain disturbances in the nervous, endocrine, immune and other body systems. It has been found that such patients have a lower melatonin (MT) production in da…
Researchers of the St. Petersburg Institute of Bioregulation and Gerontology of the North-Western Branch of the Russian Academy of Medical Sciences and the Research Institute of Gerontology of the Ukrainian Academy of Medical Sciences (Kiev) clinical…
The effect of synthetic pineal peptide Epitalon (Ala-Glu-Asp-Gly) on colon carcinogenesis was firstly studied in rats. Eighty 2-month-old outbred male LIO rats were subdivided into four groups and were weekly exposed to five subcutaneous injections o…
The age-related changes in the pineal gland are functional rather than organic, which makes their correction or prevention more tenable. The amelioration or inhibition of some age-related impairments of the pineal gland were observed with dietary res…
There was studied the effect of polypeptide preparations isolated from the cerebral cortex (Cortexin), epiphysis (Epithalamin), liver (Hepalin), thymus (Thymalin) and small synthetic peptides--Cortagen, Epitalon, Livagen, Vilon on the development of…
Hepatitis B viral (HBV) infection is a major health burden in the Asia-Pacific region. The seriousness of chronic hepatitis B (CHB) is often realized at a late stage. The resultant morbidity and mortality from cirrhosis complications is considerable,…
BACKGROUND: Interferon treatment for chronic hepatitis B has low efficacy and is associated with serious side effects. It is therefore important to assess the role of other drugs in the treatment of this condition. AIMS: To assess the efficacy and sa…
In continuation with the earlier and ongoing studies on Thymosin-alpha-1 (Talpha1) exerting its immunomodulatory effects on various components of the immune system including T-cells, NK-cells, blood lymphocytes and macrophages, the role of Talpha1 in…
BACKGROUND/AIMS: The most prevalent type of chronic hepatitis B in Turkey is anti-HBe-positive. No consistently effective therapy is yet available for the treatment of these patients. The aim of this study was to assess the efficacy and safety of int…
Hepatitis B, a major viral infection that can lead to cirrhosis and hepatocellular carcinoma, is the ninth most common cause of death worldwide. Prevention of hepatitis B virus transmission is key to reducing the spread of this serious condition. Man…
Mammalian thymic histogenesis can be morphologically divided into three consecutive stages: 1) epithelial; 2) lymphopoietic or lympho-epithelial; and 3) differentiated cellular microenvironmental, with formation of Hassall's bodies (HBs). The marked…
We examined whether combination therapy with thymosin-alpha1 and famciclovir would induce hepatitis B e antigen seroconversion in patients with chronic hepatitis B infection in the immune-tolerant phase without inducing significant hepatic necro-infl…
The effects of thymosin alpha1 (Talpha1) on mammary carcinogenesis was investigated in Fisher rats. Mammary carcinomas were observed 3 months after N-nitrosomethylurea (NMU) injection (10mg, i.p.) into Fisher rats. Daily administration of Talpha1 (10…
Thymosin alpha1 (Talpha1), a synthetic 28-amino acid peptide with multiple biological activities primarily directed towards immune response enhancement, was originally developed by Alpha 1 Biomedicals for the treatment of hepatitis B virus (HBV) infe…
The promoter regions of several neuron-specific structural proteins (e.g. neurofilaments, peripherin, Talpha1-tubulin) have revealed potential regulatory elements that could contribute to the choice of a neuronal phenotype during development. We init…
Mammalian neurogenesis is determined by an interplay between intrinsic genetic mechanisms and extrinsic cues such as growth factors. Here we have defined a signaling cascade, a MEK-C/EBP pathway, that is essential for cortical progenitor cells to bec…
