Interleukin-33 (IL-33) has now emerged as a cytokine with diverse and pleiotropic functions in various infectious and inflammatory diseases. IL-33 is expressed by epithelial cells, endothelial cells, fibroblasts, and hepatocytes. The target cells of IL-33 are Th2 cells, basophils, dendritic cells, mast cells, macrophages, NKT cells, and nuocytes, newly discovered natural helper cells/innate lym...
Immunoproliferative small intestinal disease (IPSID) is prevalent in the Mediterranean region and in many Third World countries but is rare in Southeast Asia. Between 1980-1990, 4 cases of IPSID were admitted to Ramathibodi Hospital, Bangkok. Three were males and the mean age was 32 +/- 20.2 years. All patients presented with chronic diarrhea of 7 months to 6 years duration, and weight loss of ...
Artemisinins are plant products with a wide range of medicinal applications. Most prominently, artesunate is a well tolerated and effective drug for treating malaria, but is also active against several protozoal and schistosomal infections, and additionally exhibits anti-angiogenic, anti-tumorigenic and anti-viral properties. The array of activities of the artemisinins, and the recent emergence...
Infection by helminths (worms) may be limited solely to the intestinal lumen or may involve a complex process with migration of the adult or immature worm through the body before localization in a particular tissue. Complicating our understanding of the host– parasite relationship and the role of chemotherapy in helminth-induced infections is the complex life cycle of many of these organisms.Wh...
CDC, the Infectious Disease Society of America, and the American Society of Blood and Marrow Transplantation have cosponsored these guidelines for preventing opportunistic infections (OIs) among hematopoietic stem cell transplant (HSCT) recipients. The guidelines were drafted with the assistance of a working group of experts in infectious diseases, transplantation, and public health. For the pu...
Recently, considerable attention has been focused on dietary and medicinal phytochemicals that inhibit, reverse or retard diseases caused by oxidative and inflammatory processes. Vernonia amygdalina is a perennial herb belonging to the Asteraceae family. Extracts of the plant have been used in various folk medicines as remedies against helminthic, protozoal and bacterial infections with scienti...
During infection, CD4(+) Th cell responses polarize to become primarily Th1 or Th2. Th1 cells, which make IFN-gamma, are crucial for immunity to many bacterial and protozoal infections, whereas Th2 cells, which make IL-4, IL-5, and IL-13, are important for resistance to helminth infections. Polarized Th1 responses are induced by dendritic cells (DCs), which respond to pathogen-derived TLR ligan...
In light of evidence that high-dose iron supplements lead to a range of adverse events in low-income settings, the safety and efficacy of lower doses of iron provided through biological or industrial fortification of foodstuffs is reviewed. First, strategies for point-of-manufacture chemical fortification are compared with biofortification achieved through plant breeding. Recent insights into t...
Measurement of ruminal microbial protein is necessary to quantify ruminal escape of dietary protein and microbial yields. Microbial markers used most widely have been the internal markers, diaminopimelic acid and nucleic acids (RNA, DNA, individual purines and pyrimidines, or total purines), and the external isotopic markers (e.g., 15N and 35S). Combined with digesta flow markers in ruminally a...
