Glutamine (GLN) is commonly known as an important metabolite used for the growth of cancer cells but the effects of its intake in cancer patients are still not clear. However, GLN is the main substrate for DNA and fatty acid synthesis. On the other hand, it reduces the oxidative stress by glutathione synthesis stimulation, stops the process of cancer cachexia, and nourishes the immunological system and the intestine epithelium, as well. The current paper deals with possible positive effects of GLN supplementation and conditions that should be fulfilled to obtain these effects. The analysis of GLN metabolism suggests that the separation of GLN and carbohydrates in the diet can minimize simultaneous supply of ATP (from glucose) and NADPH2 (from glutamine) to cancer cells. It should support to a larger extent the organism to fight against the cancer rather than the cancer cells. GLN cannot be considered the effective source of ATP for cancers with the impaired oxidative phosphorylation and pyruvate dehydrogenase inhibition. GLN intake restores decreased levels of glutathione in the case of chemotherapy and radiotherapy; thus, it facilitates regeneration processes of the intestine epithelium and immunological system.
Long-term fluoroquinolone-associated disability (FQAD) after fluoroquinolone (FQ) antibiotic therapy appears in recent years as a significant medical and social problem, because patients suffer for many years after prescribed antimicrobial FQ treatment from tiredness, concentration problems, neuropathies, tendinopathies, and other symptoms. The knowledge about the molecular activity of FQs in the cells remains unclear in many details. The effective treatment of this chronic state remains difficult and not effective. The current paper reviews the pathobiochemical properties of FQs, hints the directions for further research, and reviews the research concerning the proposed treatment of patients. Based on the analysis of literature, the main directions of possible effective treatment of FQAD are proposed: (a) reduction of the oxidative stress, (b) restoring reduced mitochondrion potential ΔΨm, (c) supplementation of uni- and bivalent cations that are chelated by FQs and probably ineffectively transported to the cell (caution must be paid to Fe and Cu because they may generate Fenton reaction), (d) stimulating the mitochondrial proliferation, (e) removing FQs permanently accumulated in the cells (if this phenomenon takes place), and (f) regulating the disturbed gene expression and enzyme activity.
(1) Our results testify that the combination of a low-calorie diet and laser acupuncture is characterized by a higher efficacy than a low-calorie diet alone in lowering body weight, body mass index and waist-to-hip-ratio. (2) Laser acupuncture is an additional useful healing method in the therapy of visceral postmenopausal obesity.
IntroductionBreast cancer is the most common malignant tumour among women. About 15,000 new cases of breast cancer are diagnosed and more than 5,000 women die in Poland every year. The aim of this study was to analyse the incidence and mortality rate of breast cancer among women in Poland in the years 2001-2010.Material and methodsAnalysed data concerning the incidence of and mortality from cancer among women were obtained from the National Cancer Registry.ResultsThe number of new cases reported in 2010 exceeded that reported in 2001 by 3,666. The mortality from breast cancer among women increased by 15.1% by 2009, to subsequently drop by 0.3% in 2010. The standardized incidence rate increased by 7.4 and the standardized mortality rate fell by 1.3 in 2001-2010.ConclusionsIn the years 2001-2010 the incidence of breast cancer in women in Poland rose by 30.3%, with an increase of 7.4 in the incidence rate. The highest rise in the incidence and mortality of women due to breast cancer in Poland is reported in the Lodz voivodeship. In the years 2001-2009 the number of women's deaths due to breast cancer increased slightly, while the mortality rate dropped.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
