Altered Proteins in the Hippocampus of Patients with Mesial Temporal Lobe Epilepsy.

Mesial temporal lobe epilepsy (MTLE) is usually associated with drug-resistant seizures and cognitive deficits. Efforts have been made to improve the understanding of the pathophysiology of MTLE for new therapies. In this study, we used proteomics to determine the differential expression of proteins in the hippocampus of patients with MTLE compared to control samples.

Characterization and role of the 3-methylglutaconyl coenzyme A hidratase in Trypanosoma brucei.

Trypanosoma brucei, the agent of African Trypanosomiasis, is a flagellated protozoan parasite that develops in tsetse flies and in the blood of various mammals. The parasite acquires nutrients such as sugars, lipids and amino acids from their hosts. Amino acids are used to generate energy and for protein and lipid synthesis.

In vivo HIV-1 hypermutation and viral loads among antiretroviral-naive Brazilian patients.

Hypermutation alludes to an excessive number of specific guanine-to-adenine (G- >A) substitutions in proviral DNA and this phenomenon is attributed to the catalytic activity of cellular APOBECs. Population studies relating hypermutation and the progression of infection by human immunodeficiency virus type 1 (HIV-1) have been performed to elucidate the effect of hypermutation on the natural course of HIV-1 infection. However, the many different approaches employed to assess hypermutation in nucleotide sequences render the comparison of results difficult.
