Stabilin-2 was recently identified as a novel receptor for membrane phosphatidylserine of apoptotic cells. To identify proteins that were candidates for stabilin-2 cytoplasmic domain binding, we screened a human spleen cDNA library using the yeast tw…
One hundred Hampshire x Duroc cross-bred pigs and 100 Nebraska Index line pigs were infected with porcine reproductive and respiratory syndrome virus (PRRSV) and evaluated for resistance and susceptibility. Controls (100/line) were uninfected litterm…
BACKGROUND: The mechanisms underlying psoriatic pathogenesis are not fully understood and might be elucidated by identifying novel disease-related molecular markers, including autoantigens. METHODS: We used 2 proteomic methods to analyze plasma sampl…
Thymosin beta4 (Tbeta(4)) is a naturally occurring, ubiquitous, non-toxic protein with documented wound-healing, anti-inflammatory, anti-apoptotic, and tissue-repair properties in skin, the ocular surface, and the heart. The ability of Tbeta(4) to de…
BACKGROUND: Up to now, many "immunoactive" brain areas have been identified, such as hypothalamic nuclei, brain reward system; but the nucleus ambiguous (Amb), a nucleus nervi vagis of medulla oblongata, was less well studied in neuroimmunomodulation…
OBJECTIVE: To explore the mechanism of recombinant thymosin beta4 (Tbeta4) accelerating skin wound healing in rats by regulating laminin 5 expression. METHODS: Two full thickness 8 mm punch wounds were made at the costovertebral angle on dorsal surfa…
Myocardial damage is frequently occurring upon a prolonged period of ischemia, although subsequent reperfusion as standard therapy is established. Among the pleiotropic causes of ischema-reperfusion injury, loss of cardiomyocytes, microcirculatory di…
OBJECTIVE: We have applied fluorimetric method to monitor aldehyde dehydrogenase (ALDH*) activity in human saliva samples to study inactivation, reactivation and inhibition of the enzyme. DESIGN: Saliva samples were collected to buffer stock solution…
The crystallographic structure of the family 3 polysaccharide lyase (PL-3) PelI from Erwinia chrysanthemi has been solved to 1.45 A resolution. It consists of an N-terminal domain harboring a fibronectin type III fold linked to a catalytic domain dis…
The purpose of this study was to examine the effects of 5 d of creatine (Cr) loading on the electromyographic fatigue threshold (EMG FT) in college-age men. Sixteen men (age 22.4 +/- 2.6 yr, height 177.4 +/- 6.8 cm, weight 79.5 +/- 10.6 kg; M +/- SD)…
OBJECTIVE AND DESIGN: In the presented study we compared the effect of stable peptide BPC 157 and methylprednisolone on early functional recovery after Achilles tendon to bone transection in a rat model before collagen healing started. MATERIAL AND M…
Secondary metabolites of Solanaceae plants, sharing tropane skeleton as a common structural feature, are sharply divided into two classes: tropine and ecgonine derivatives. The first group, represented by well known alkaloids: atropine and scopolamin…
The article presents the data of the clinical study aimed at the search for effective means of treatment and prophylaxis of complications for female ischemic heart disease patients of senior age groups. Analysis of the study results shows that the ad…
Tetrapeptides Lys-Glu-Asp-Gly and Ala-Glu-Asp-Gly were synthesized on the basis of amino acid composition of pituitary cytomedins. Administration of these tetrapeptides to hypophysectomized chickens for 40 days was followed by an increase in the conc…
Experimental relationship between the hyperchromic effect of DNA [poly(dA-dT):poly(dA-dT)] interacting with Ala-Glu-Asp-Gly peptide is presented by a saturation isotherm. The free DNA double strand is melting (the strands separate) at 69.5 degrees C…
Talpha1 (thymosin alpha 1) is important in treating immunodeficiency and other diseases. In order to study the feasibility of expressing Talpha1 in plants, as the first attempt, we designed and synthesized the Talpha1 gene according to the plant codo…
FoxP3(+) regulatory T (Treg) cells are important mediators of peripheral tolerance, and deficiency of this population is associated with autoimmune inflammation and onset of acute lethal graft-vs.-host disease in transplantation. Type I IFN-producing…
Chronic hepatitis B virus (HBV) infection is a serious problem because of its worldwide distribution and possible adverse sequelae, such as cirrhosis and hepatocellular carcinoma. Thymosin alpha-1 (Talpha1) is an immune modifier that has been shown t…
Thymosin alpha-1 (Talpha1) has been shown to be effective in chronic hepatitis B treatment. This study investigated the effect of Talpha1 and interferon-alpha (IFNalpha) on cytokine production by peripheral blood mononuclear cells (PBMCs) of 12 patie…
BACKGROUND AND AIM: Monotherapy of lamivudine, interferon-alpha (IFN-alpha), and thymosin alpha-1 (Talpha1) is unlikely to be sufficient for the eradication of a chronic hepatitis B virus (HBV) infection. The aim of our study is to elucidate whether…
