Isolation and characterization of a factor from calf serum that promotes the pigmentation of embryonic and transformed melanocytes

Isolation and characterization of a bovine herpesvirus 3 From cases of calf pneumonia in Iran

Serum level of vitamin D3 in vitiligo patients before and after treatment with narrow band UVB. Is there an association with treatment?

Background: Vitiligo is a pigmentation disorder of the skin characterized by the loss of melanocytes through different mechanisms. Narrow band UVB (NBUVB) is a safe and effective treatment for vitiligo that acts by inducing the synthesis of cytokines involved in melanogenesis. NBUVB appears to be involved in the treatment of vitiligo by increasing the synthesis of vitamin D, which prevents the ...

Production, Purification and Characterization of Chicken Egg Yolk Monoclonal Antibody Against Colonization factor antigen -1 of Enterotoxigenic Escherichia coli Causing Diarrhea

Enterotoxigenic Escherichia coli (ETEC) causes diarrhea in both humans and animals. The contaminated food and water are the most common vehicles for ETEC infection. The colonization factor antigen (CFA-1) is a fimbriae protein that promotes adherence of the ETEC strain to the epithelium of the small intestine of the host. In this study IgY proteins were produced against the CFA-1 of ETEC in imm...

EFFECTS OF SERUM AND PROTEIN SYNTHESIS INHIBITORS ON POLYMORPHONUCLEAR NEUTROPHIL APOPTOSIS

In this study the programmed cell death (apoptosis) of human neutrophilic granulocytes was investigated in the presence and absence of fetal calf serum (FCS), cycloheximide and actinomycin-D. The results show that when FCS is omitted from cultures, apart from a decrease in viability, the percentage of apoptotic cells and DNA fragmentation increases. Apoptosis is accelerated in serum withdra...

Serum Levels of Thyroid Hormones and Vitamin D in Women with Melasma

Background and purpose: Melasma is a common skin pigmentation disorder that manifests as hyperpigmented macules and patches. Genetic predisposition, sun exposure, and pregnancy are known risk factors for melasma. Previous studies have suggested that thyroid disorders may be associated with melasma. Given the fact that vitamin D affects and stimulates the production of melanin by melanocytes, th...
