Red wine contains many compounds that may have therapeutic use, including resveratrol (3,4',5-trihydroxytrans- stilbene). Since resveratrol could be administered both in the diet and as a therapeutic agent, defining appropriate concentrations requires understanding of the pharmacokinetics. Resveratrol absorption is rapid but plasma concentrations are low as it is rapidly and efficiently converted into relatively hydrophilic phas Read More

For many years, the purine salvage pathway of parasitic protozoa has been regarded as an attractive chemotherapeutic target. Parasitic protozoa lack de novo synthesis and rely entirely on the purine salvage pathway to meet their purine demands. Because of the great phylogenetic difference between parasite and host, there are often sufficient distinctions that can be exploited to design specific inhibitors for the parasitic enzy Read More

Huntington's disease (HD) is a genetic neurodegenerative process whose etiology is based on a localized disturbance in the short arm of chromosome 4 that encodes the huntingtin protein (Htt). The elongation of triple CAG for glutamine characterizes this change. Mutated Htt (mHtt) causes the appearance of intracellular aggregates inducing alterations in mitochondrial metabolism in the form of reactive oxygen speci Read More

Positron emission computed tomography (PET) is a functional, noninvasive method for imaging regional metabolic processes that is nowadays most often combined to morphological imaging with computed tomography (CT). Its use is based on the well-founded assumption that metabolic changes occur earlier in tumors than morphologic changes, adding another dimension to imaging. This article will review the established Read More

The anticoagulant behavior of sulfated polysaccharides from seaweeds is reviewed based on their chemical structures. Analysis of the literature suggested that the driving force for the formation of the sulfated polysaccharide/ protein complex is the non-specific polar interaction between the negatively and positively charged groups in the polysaccharide and protein, respectively and that the complex is further stabilized by sh Read More

Hirsutism is the presence of excess hair growth in women in the typical male hair growth areas, thereby reflecting a deviation from the normal female hair pattern. It affects from 5% to 10% of women, depending on age, menopausal status and ethnic background. The presence of hirsutism is very distressing for women, and subsequently may have a negative impact on their psychosocial life. In the treatment of hirsutism sev Read More

Reactive oxygen species (ROS) generated by cigarette smoke may contribute to lung and oral cancer. The 18 kDa Translocator protein (TSPO) has been reported to be affected by ROS as well as to participate in ROS generation at mitochondrial levels, and has been implicated in pro-apoptotic and anti-carcinogenic functions. The present study reports the presence of TSPO in the cellular fraction of human saliva. In cells collecte Read More

Lycopene, a natural carotenoid found in tomato, has been reported to possess various health benefits, such as cardiovascular and cancer preventive properties. However, the experimental basis for such health benefits is not fully understood. One of the possible mechanisms for its protective activities is by down-regulation of the inflammatory response. That includes the inhibition of pivotal pro-inflammatory mediat Read More
