Multivalent GU-rich oligonucleotides sequester TDP-43 in the nucleus by inducing high molecular weight RNP complexes.

TDP-43 nuclear clearance and cytoplasmic aggregation are hallmarks of TDP-43 proteinopathies. We recently demonstrated that binding to endogenous nuclear GU-rich RNAs sequesters TDP-43 in the nucleus by restricting its passive nuclear export. Here, we tested the feasibility of synthetic RNA oligonucleotide-mediated augmentation of TDP-43 nuclear localization.

Anticonvulsant mechanisms of the ketogenic diet and caloric restriction.

Many treatments have been proposed to control epileptic seizures, such as the ketogenic diet and caloric restriction. However, seizure control has not yet been improved completely in all patients. Probably, due to the lack of understanding regarding this neurological disorder pathogenesis or pathophysiology, including its molecular approach.

The role of specialized hospital units in infection and mortality risk reduction among patients with hematological cancers.

Motivation: Patients with hematological malignancies are susceptible to life-threatening infections after chemotherapy. The current study aimed to evaluate whether management of such patients in dedicated inpatient and emergency wards could provide superior infection prevention and outcome.

Methods: We have developed an approach allowing to retrieve infection-related information from unstructured electronic medical records of a tertiary center.

Evaluation of the Antioxidant and Antiproliferative Effects of Three Peptide Fractions of Germinated Soybeans on Breast and Cervical Cancer Cell Lines.

Soybeans are an important source of bioactive molecules, such as peptides, which generation can improve through germination. In this study, the antioxidant and antiproliferative activities of three peptide fractions (>10 kDa, 5-10 kDa and <5 kDa) that were obtained by ultrafiltration of soybean protein hydrolysate after six days of germination were evaluated. The antioxidant activities of the peptide fractions were assessed by reducing power, Cu and Fe chelation and OH· scavenging assays, whereas their antiproliferative effects against cervical (HeLa, SiHa, CasKi) and breast (MCF7 and MDA-MB-231) cancer cell lines were evaluated by the MTT assay.

Antinociceptive effect of aqueous extracts from the bark of Croton guatemalensis Lotsy in mice.

Croton guatemalensis Lotsy (CGL), known as "copalchi" in Chiapas, Mexico, is used for the treatment of fever, abdominal pain and malaria and also as a remedy for chills and for treating rheumatism. The aim of this study was to evaluate whether aqueous extracts from the bark of this plant possesses indeed antinociceptive properties by using two different animal models of nociception, the acetic acid-induced writhing test and the hot plate model. The results showed that i.
