KIR genotyping in the selected population in Andhra Pradesh (India).

Background: The population is not always homogeneous in relation to the representation and functioning of genes. Therefore, the presence of allogenicity is a universal phenomenon. The profound variability is noticed among the members of the human population with reference to the resistance against infections and late onset of diseases.

Infective endocarditis--a tale of two cases and the lessons (re)learned.

Infective endocarditis due to uncommon organisms or at uncommon sites presents a diagnostic challenge. Because signs and symptoms can be nonspecific and vary greatly, a high index of suspicion is necessary. We have recently treated two such cases, one due to HACEK organism (Eikenella corrodens) in a patient with established valvular heart disease and other of right sided endocarditis due to Pseudomonas aeruginosa.

Diabetes--role of epigenetics, genetics, and physiological factors.

Cells of organ systems are endowed with a relatively similar genome while epigenome niches keep varying chronologically and defined explicitly in the respective tissues. The genome of an individual is always influenced by parental, embryonic, tissue-specific, and environmental epigenomes and the same must have been the possible reason for invariable inquiries relating to familial, environmental and life style patterns in the preliminary investigations of diabetic complications. Unprecedented methylation of lysine residues of histones and cytosines of CpG islands of promoter DNA impede the transcription of genes and homocysteine is the metabolic key player of methyl groups.
