Pivotal role of intestinal cholesterol and nuclear receptor LXR in metabolic liver steatohepatitis and hepatocarcinoma.

Hepatocellular carcinoma (HCC) incidence is continuously increasing worldwide, due to the rise of metabolic dysfunction-associated steatohepatitis (MASH) cases. Cholesterol is an essential driver of the metabolic dysregulations that promote HCC progression. Liver X Receptor (LXR) is a nuclear receptor best known for the regulation of lipid and cholesterol homeostasis, with a prominent function in the liver and in the intestine.

Randomised, double-blind, placebo-controlled study of pivagabine in neurasthenia.

One hundred and eighteen patients with neurasthenia, as defined by ICD 10 (International Classification of Diseases), participated in a randomised, double-blind, placebo-controlled trial of pivagabine (4-[(2,2-dimethyl-1-oxopropyl)amino]butanoic acid, CAS 69542-93-4, Tonerg). Pivagabine 1800 mg/d was administered orally for four weeks. At the end of the trial, active medication was significantly superior to placebo on the Clinical Global Impression (CGI) improvement of illness scale.

Clinical effectiveness of lamotrigine and plasma levels in essential and symptomatic trigeminal neuralgia.

This paper reports on the effectiveness of oral lamotrigine in 15 patients suffering from "essential" trigeminal neuralgia and in five patients suffering symptomatic trigeminal neuralgia concomitant with multiple sclerosis. We recorded objective and subjective pain ratings and correlated them to daily dosage (400 mg maximum) and plasma levels of the drug. We detected pain relief proportional to daily dosage and to drug plasma levels.

Neuropsychological test performances and normal aging.

This study was designed to assess the relevance of normal aging to performance in a variety of neuropsychological tests, in a wide range of age groups. The battery included tests of several cognitive abilities of varying complexity (attention, orientation, memory, self-regulation, categorial ability and so on). The results showed that some tests (Orientation, Attention, Digit Span, Naming, Block Design, Self-regulation, Calculation, Weigl) are not significantly affected by aging while in others performance clearly declines with age.
