Metabonomics study of urine and plasma in depression and excess fatigue rats by ultra fast liquid chromatography coupled with ion trap-time of flight mass spectrometry.

Numai utilizatorii înregistrați pot traduce articole

A novel metabonomic method based on fast liquid chromatography coupled with ion trap-time of flight mass spectrometry (UFLC/MS-IT-TOF) was applied to study the metabolic changes of plasma and urine in depression and excess fatigue rats. Principal component analysis (PCA) and partial least

A Pilot Study of Metabolomic Pathways Associated With Fatigue in Survivors of Colorectal Cancer

Numai utilizatorii înregistrați pot traduce articole

Background: Over 30% of cancer survivors experience chronic fatigue. An alteration in energy metabolism is one of the hypothesized mechanisms for cancer-related fatigue (CRF). No studies have evaluated for changes in metabolic profiles in

Early life-stage effects in medaka (Oryzias latipes) following in ovo exposure to polyamine biosynthetic inhibitors.

Numai utilizatorii înregistrați pot traduce articole

Medaka, Oryzias latipes, were exposed in ovo to the polyamine (PA) biosynthesis inhibitors alpha-difluoromethylornithine (DFMO) and methylglyoxal bis(guanylhydrazone) (MGBG). In an additional group, spermine, the end product of the PA pathway, was added with DFMO and MGBG for a "rescue" treatment.

Effects of modulation of nitric oxide on rat diaphragm isotonic contractility during hypoxia.

Numai utilizatorii înregistrați pot traduce articole

Nitric oxide (NO) is essential for optimal myofilament function of the rat diaphragm in vitro during active shortening. Little is known about the role of NO in muscle contraction under hypoxic conditions. Hypoxia might increase the NO synthase (NOS) activity within the rat diaphragm. We hypothesized

Effects of an Extract of Salmon Milt on Symptoms and Serum TNF and Substance P in Patients With Fibromyalgia Syndrome.

Numai utilizatorii înregistrați pot traduce articole

The aim of this study was to evaluate the effects of a dietary supplement containing primarily an extract of salmon's milt (semen) on symptoms and blood levels of proinflammatory molecules in patients with fibromyalgia syndrome (FMS), a chronic, painful musculoskeletal disease without

RNA and protein synthesis in rat brain during exercise. Effect of arginine and some phosphorylated amino acids.

Numai utilizatorii înregistrați pot traduce articole

RNA and protein synthesis is noticeably depressed in the brain of swimming rats. Repeated oral administration of phosphothreonine, phosphoserine or arginine is susceptible of improving brain macromolecular synthesis. A parallel induction is observed on spermine and spermidine accumulation,

Phase 1 study of N(1),N(11)‑diethylnorspermine (DENSPM) in patients with advanced hepatocellular carcinoma.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE N(1),N(11)-diethylnorspermine (DENSPM), a synthetic analog of the naturally occurring polyamine spermine, can induce polyamine depletion and inhibit tumor cell growth. The objectives of this phase I study were to assess the safety, maximum-tolerated dose (MTD), pharmacokinetics, and

A Phase I Dose-Escalation Study of the Polyamine Analog PG-11047 in Patients With Advanced Solid Tumors

Numai utilizatorii înregistrați pot traduce articole

Purpose: Polyamines are essential for the sustained proliferation and biomass required by tumor cells. Bis-alkylated polyamine analogs are nonfunctional competitors of natural polyamines. Of these, PG-11047, a second-generation unsaturated analog of the polyamine

A phase I and pharmacokinetic study of SAM486A, a novel polyamine biosynthesis inhibitor, administered on a daily-times-five every-three-week schedule in patients with Advanced solid malignancies.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE SAM486A is a novel inhibitor of the polyamine biosynthetic enzyme S-adenosylmethionine decarboxylase (SAMDC). This study was performed to characterize the toxicity profile and the pharmacological behavior and to determine the maximum tolerated dose (MTD) of SAM486A administered by a 1-h

The genus Tragopogon (Asteraceae): A review of its traditional uses, phytochemistry, and pharmacological properties.
