Recently it has been suggested that glyceraldehyde-3-phosphate dehydrogenase (GAPDH) play a role in nuclear tRNA export. As the structural basis of binding of GAPDH to tRNA is as yet unknown, we have employed Raman and CD spectroscopy as probes of the solution structures of GAPDH from rabbit and tRNA(Phe) from brewers yeast. Additionally, we have obtained(More)
Disease phenotypes and defects in function can be traced to nonsynonymous single nucleotide polymorphisms (nsSNPs), which are important indicators of action sites and effective potential therapeutic approaches. Identification of deleterious nsSNPs is crucial to characterize the genetic basis of diseases, assess individual susceptibility to disease,(More)
The population is aging. Over the coming years, the incidence of age-related chronic diseases such as cancer is expected to continue to increase. Phytochemicals, which are non-nutritive chemicals found in plants and food, have emerged as modulators of key cellular signaling pathways exerting proven anticancer effects. The challenge now is to develop(More)
The incidence of obesity is rising at an alarming rate and is becoming a major public health concern with incalculable social costs. Indeed, obesity facilitates the development of metabolic disorders such as diabetes, hypertension, and cardiovascular diseases in addition to chronic diseases such as stroke, osteoarthritis, sleep apnea, some cancers, and(More)
Amphetamines are psychostimulants abused by man, that eventually leads to drug dependence. Amphetamine administration to rodents has been shown to provoke significant neurotoxicity involving dopaminergic nerve terminal degeneration. However, little information related to the effect of amphetamines on reactive oxygen species (ROS) production and(More)
This study reports the changes in lipids and proteins of different brain areas of nicotine, D+-amphetamine, and nicotine and D+-amphetamine treated rats by monitoring lipid peroxidation and protein beta-sheet formation using infrared microspectroscopy. Compared with the untreated brain samples, the peroxide level is relatively higher in the(More)
We have studied the thermal denaturation of native basic pancreatic trypsin inhibitor (BPTI) by monitoring the Raman bands in the 4000-400 cm(-1) range. In agreement with results obtained by calorimetry, a cooperative melting transition is observed starting at 75 degrees C. This transition is found to involve predominantly the unfolding of helical(More)
Fruit and vegetables are essential components of a healthy diet. The World Health Organization (WHO) recommends an intake of five to eight portions (400-600 g) daily of fruits and vegetables to reduce risk of cardiovascular disease, cancer, poor cognitive performance, and other diet-related diseases, as well as for the prevention of micronutrient(More)
Non-synonymous single nucleotide polymorphisms (nsSNPs) are genetic variations that affect the encoded protein by an amino acid change. In humans, many naturally-occurring nsSNPs cause protein dysfunction and increase vulnerability to disease. Identification of such nsSNPs provides an important opportunity to develop drugs/nutrients with precise therapeutic(More)
Dandelion (Taraxacum officinale Weber) is a member of the Asteraceae (Compositae) family, native to Europe but widely distributed in the warmer temperate zones of the Northern Hemisphere. Dandelion and its parts are habitually consumed as plant foods in several areas of the world, where they are also employed in phytotherapy. Indeed, dandelion contains a(More)
