Physical exercise neuroprotects ovariectomized 3xTg-AD mice through BDNF mechanisms.
2014
Postmenopausal women may be more vulnerable to cognitive loss and Alzheimer's disease (AD) than premenopausal women because of their deficiency in estrogens, in addition to their usually older age. Aerobic physical exercise has been proposed as a therapeutic approach for maintaining health and well-being in postmenopausal women, and for improving brain health and plasticity in populations at high risk for AD. To study the neuroprotective mechanisms of physical exercise in a postmenopausal animal model, we submitted previously ovariectomized, six-month old non-transgenic and 3xTg-AD mice to three months of voluntary exercise in a running wheel. At nine months of age, we observed lower grip s…
Review and update on drugs related to the development of osteonecrosis of the jaw
2019
Conflict of interest Conclusions of the working group on “New drugs related to the de-velopment of osteonecrosis of the jaw”. Spanish Society of Cranio-mandibular Dysfunction and Orofacial Pain and Spanish Society of Oral Medicine SEDCYDO-SEMO joint International Meeting: 30th SEDCYDO annual meeting & 15th SEMO Congress. Bilbao (Spain); June, 2019. [EN] Background: Medication-related osteonecrosis of the jaw (MRONJ) is a rare, but serious adverse effect of cer-tain drugs, of which bisphosphonates are the most widely known. This pathology is also associated with other medications such as the biologic antiresorptive agent, denosumab and some antiangiogenics such as sunitinib, bevacizumab or a…
Improving opportunities for effective management of gastro-oesophageal reflux disease
2002
The recent introduction of proton pump inhibitors has extraordinarily improved the therapeutic approach to gastro-oesophageal reflux disease. The concept of decreasing gastric acid secretion and increasing the pH in the lower oesophagus has been demonstrated to be therapeutically effective and the higher the level of pH achieved, the better the results. In spite of the evident efficacy of these molecules, there are still many patients who will continue to have symptoms despite medical treatment. Proton pump inhibitors suppress gastric acidity, but this effect shows a remarkable interindividual variation depending on different reasons. Thus, it is still possible to optimise medical therapy f…
Dithiothreitol prevents age-associated decrease in oocyte/conceptus viability in vitro.
1998
The present study was designed to ascertain whether the negative effects on reproductive potential of post-ovulatory ageing in vitro of oocytes can be prevented by antioxidant therapy. Mouse metaphase II (MII) oocytes were aged in vitro for 12 h prior to insemination in the presence of varying concentrations of L-ascorbic acid, 6-methoxy-2,5,7,8-tetramethylchromane-2-carboxylic acid (Trolox), L-cystine dihydrochloride, ethylenediaminetetraacetic acid (EDTA), beta-mercaptoethanol and DL-dithiothreitol (DTT). In-vitro ageing of oocytes was associated with lower fertilization rate, higher proportion of concepti exhibiting cellular fragmentation at 24 h post-insemination and lower percentage of…
Carboxyl nonsteroidal anti-inflammatory drugs are efficiently glucuronidated by microsomes of the human gastrointestinal tract.
2004
Limited studies have been carried out on the biotransformation of carboxyl nonsteroidal anti-inflammatory drugs (NSAIDs) in the liver. However, the role of the intestine in NSAID metabolism has not been investigated. In this report, the contribution of UDP-glucuronosyltransferases (UGTs) in the human gastrointestinal (GI) tract from five donors to the glucuronidation of the NSAIDs, RS-ketoprofen, S-naproxen, RS- and S-etodolac, was investigated. UGT activity and, for some donors, mRNA levels were evaluated. All NSAIDs were glucuronidated throughout the GI tract; however, glucuronidation was low in stomach and duodenum as compared to the remainder of the intestine. RT-PCR analysis demonstrat…
Incidence, prevalence and clinical correlates of antidepressant-emergent mania in bipolar depression: a systematic review and meta-analysis.
2018
Background: Treatment-emergent mania (TEM) represents a common phenomenon inconsistently reported across primary studies, warranting further assessment. Methods: A systematic review and meta-analysis following the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) and Meta-Analysis of Observational Studies in Epidemiology (MOOSE) guidelines were conducted. Major electronic databases were searched from inception to May 2017 to assess the incidence and prevalence rates and clinical features associated with manic switch among bipolar depressed patients receiving antidepressants, using meta-regression and subgroup analysis. Results: Overall, 10 098 depressed patients wit…
Level of response and safety of pharmacological monotherapy in the treatment of acute bipolar I disorder phases: a systematic review and meta-analysi…
2010
In recent years, combinations of pharmacological treatments have become common for the treatment of bipolar disorder type I (BP I); however, this practice is usually not evidence-based and rarely considers monotherapy drug regimen (MDR) as an option in the treatment of acute phases of BP I. Therefore, we evaluated comparative data of commonly prescribed MDRs for both manic and depressive phases of BP I. Medline, PsycINFO, EMBASE, the Cochrane Library, the ClinicalStudyResults.org and other data sources were searched from 1949 to March 2009 for placebo and active controlled randomized clinical trials (RCTs). Risk ratios (RRs) for response, remission, and discontinuation rates due to adverse …
Characteristics of bipolar disorder patients given antidepressants
2012
Evidence concerning efficacy of antidepressants in bipolar disorder remains inconsistent and inconclusive. As the appropriate clinical use for such patients remains unclear, we characterized outpatients with bipolar disorders who were or were not treated with antidepressants. Clinical data were collected systematically from consecutive outpatients in 11 participating Argentine mood-disorder clinics in 2007–2008. Diagnoses met DSM-IV criteria, supported by structured interviews based on the MINI-500. Of 338 outpatients diagnosed with bipolar I (45.0%), II (29.3%), or not-otherwise-specified (NOS) (25.7%) disorder, 128 (37.9%) received antidepressants. Subjects given antidepressants or not di…
Steroid activities comparison of natural and food wrap compounds in human breast cancer cell lines
2004
Abstract In this study, we tested and compared the endocrine disruption activities of compounds in materials used to package foods (bisphenol A, bisphenol F, and bisphenol A diglycidylether BADGE) with natural molecules (genistein, apigenin, kaempferol, and tangeretin) in the human breast cancer cell lines MCF-7 (ER + ) and MDA-MB453 (AR + ; GR + ). Octylphenol was also chosen as a xenoestrogen reference. Two compounds had no estrogenic activity: BADGE and tangeretin. Genistein was the most active compound in the E-Screen assay with MCF-7, followed by octylphenol, bisphenol F, bisphenol A and apigenin, with kaempferol the least potent. All estrogenic compounds competed with 17β-estradiol fo…
Improving adherence in osteoporosis: a new management algorithm for the patient with osteoporosis
2011
Introduction: Bisphosphonates are the first-choice treatment for osteoporosis. They effectively increase bone mineral density, reduce markers of bone resorption, and lower the incidence of new fractures in patients with osteoporosis-related fracture. However, the efficacy observed in clinical trials may not be realized in a real-life setting, partly due to poor adherence to therapy, with a significant worsening of clinical outcomes. Several issues contribute to poor adherence to osteoporosis medication, including inconvenient dosing regimens and concerns about possible adverse events. Although strategies to improve adherence have been investigated, new approaches are required. Areas covered…
