Nitric oxide in the pathogenesis of vascular disease

2000

Nitric oxide (NO) is synthesized by at least three distinct isoforms of NO synthase (NOS). Their substrate and cofactor requirements are very similar. All three isoforms have some implications, physiological or pathophysiological, in the cardiovascular system. The endothelial NOS III is physiologically important for vascular homeostasis, keeping the vasculature dilated, protecting the intima from platelet aggregates and leukocyte adhesion, and preventing smooth muscle proliferation. Central and peripheral neuronal NOS I may also contribute to blood pressure regulation. Vascular disease associated with hypercholesterolaemia, diabetes, and hypertension is characterized by endothelial dysfunct…

Hypovitaminosis D and orthostatic hypotension: A systematic review and meta-analysis

2016

Objectives: Orthostatic hypotension is a common condition among older adults and is associated with a range of deleterious outcomes. Recently, interest has developed in hypovitaminosis D (defined as low 25 hydroxiyVitamin D levels) as a potential risk factor for orthostatic hypotension. We conducted a systematic review and meta-analysis examining the association of orthostatic hypotension between study participants with and without hypovitaminosis D, including the adjustment of potential confounders (age, sex, BMI, renal function, comorbidities, seasonality, use of antihypertensive medications, and supplementation with cholecalciferol). Methods: A systematic literature search of major elect…

Comparative study of the efficacy of herbal antioxdants oxitard and aloe vera in the treatment of oral submucous fibrosis

2014

Objectives: Oral submucous fibrosis (OSMF) is a potentially malignant disorder predominantly seen in the Indian subcontinent due to areca nut, tobacco and their products. The aim of the present study was to compare the efficacy of oxitard and aloe vera in the management of OSMF. Material and Methods: 120 subjects with OSMF were included in the study. The patients were clinico-pathologically diagnosed and divided equally in 2 groups, Group A (oxitard group) and Group B (aloe vera group). Group A was administered 2 oxitard capsules twice daily and Group B was given 5 mg aloe vera gel to be applied topically thrice daily for 3 months. Different clinical parameters were evaluated at regular int…

Comparison of the therapeutic effects of the dietary and topical forms of Zizyphus jujuba extract on oral mucositis induced by 5-fluorouracil: a gold…

2014

Background: Oral mucositis (OM) is a common inflammatory complication among cancerous patients as an ad verse effect of chemotherapy and radiotherapy. The aim of this study was to evaluate the effects and identify the appropriate route of administration of extract of Zizyphus jujuba in 5-flurouracile induced OM induction in golden hamster. Materials and Methods: In a prospective randomized double blind animal study, OM was induced in 56 male golden hamsters by 5-FU (60 mg/kg) on days 0, 5, and 10 of the study. The cheek pouch was scratched with a sterile needle on once daily on days 3 and 4. On days 14-17, 300 mg/kg dietary and 20% Z. jujuba gel and gel base groups were treated and then com…

Alternative treatments for oral bisphosphonate-related osteonecrosis of the jaws: a pilot study comparing fibrin rich in growth factors and teriparat…

2013

Objectives: The aim of this study is to describe and compare the evolution of recurrent bisphosphonate-related osteonecrosis of the jaws (BRONJ) in patients treated with plasma rich in growth factors or teriparatide. Material and Methods: Two different types of treatments were applied in patients diagnosed of recurrent BRONJ in a referral hospital for 1.100.000 inhabitants. In the group A, plasma rich in growth factors was applied during the surgery. In the group B, the treatment consisted in the subcutaneous administration of teriparatide. All the cases of BRONJ should meet the following conditions: recurrent BRONJ, impossibility of surgery in stage 3 Ruggiero classification and absence of…

Oral mucosal diseases in anxiety and depression patients: Hospital based observational study from south India

2014

Objectives: The objective of this study was to evaluate the prevalence of different Oral Mucosal diseases in Anxiety and Depression patients. Material and Methods: A hospital based observational Study was conducted in the department of Psychiatry and department of Oral Medicine and Radiology. Patients who were diagnosed with Anxiety or Depression by the psychiatrists using Hamilton Anxiety and Depression scale were subjected to complete oral examination to check for oral diseases like Oral Lichen Planus (OLP), Recurrent Aphthous Stomatitis (RAS), and Burning Mouth Syndrome (BMS). Equal number of control group subjects were also included. Results: In this study statistically significant incr…

Apixaban and oral implications

2014

Background: Thrombotic disorders remain a leading cause of death in the Western world, and in this regard a number of anticoagulation treatment have been used, including heparins, fondaparinux, vitamin K antagonists (warfarin, acenocoumarol), and new oral anticoagulants such as apixaban. For years there has been great controversy regarding the use of anticoagulants in planning dental treatments that imply bleeding. The main concerns about using new oral anticoagulants in invasive dental procedures are bleeding due to the lack of an antidote, and the thrombotic risk of the disease for which anticoagulation was indicated in the first place. Material and Methods: A literature search was conduc…

Influence of microbiology on endodontic failure. Literature review

2019

Background: The main cause of endodontic failure is the persistence of microorganisms that cause an intraradicular or extratradicular infection and that become resistant to disinfection measures. The objective of this review is to identify the microbiota associated with endodontic failure, as well as the reasons why these microorganisms are capable of surviving basic disinfection measures. Material and Methods: Systematic search of scientific articles in the databases PubMed with the following keywords “Endodontic Infections”, “Endodontic Microbiology”, “Endodontic Failure”, “Enterococcus Faecalis”, “Endodontics Retreatment” was carried out. Case reports and articles with publication date p…

Perinatal high-fat diet increases hippocampal vulnerability to the adverse effects of subsequent high-fat feeding

2015

Epidemiological observations report an increase in fat consumption associated with low intake of n-3 relative to n-6 polyunsaturated fatty acids (PUFAs) in women of childbearing age. However, the impact of these maternal feeding habits on cognitive function in the offspring is unknown. This study aims to investigate the impact of early exposure to a high-fat diet (HFD) with an unbalanced n-6/n-3 PUFAs ratio on hippocampal function in adult rats. Furthermore, we explored the effects of perinatal HFD combined with exposure to HFD after weaning. Dams were fed a control diet (C, 12% of energy from lipids, n-6/n-3 PUFAs ratio: 5) or HFD (HF, 39% of energy from lipids, n-6/n-3 PUFAs ratio: 39) th…
