Cholesterol in Alzheimer’s Disease and other Amyloidogenic Disorders

2010

The complex association of cholesterol metabolism and Alzheimer’s disease is presented in depth, including the possible benefits to be gained from cholesterol-lowering statin therapy. Then follows a survey of the role of neuronal membrane cholesterol in Aβ pore formation and Aβ fibrillogenesis, together with the link with membrane raft domains and gangliosides. The contribution of structural studies to Aβ fibrillogenesis, using TEM and AFM, is given some emphasis. The role of apolipoprotein E and its isoforms, in particular ApoE4, in cholesterol and Aβ binding is presented, in relation to genetic risk factors for Alzheimer’s disease. Increasing evidence suggests that cholesterol oxidation p…

Efficacy of Magnetic Resonance Imaging in assessing the Prognosis of Atherosclerotic plaques in patients under Statin Therapy: A Systematic Review of…

2021

The current study aims to conduct a systematic review on the efficacy of Magnetic Resonance Imaging (MRI) in assessing the Prognosis of Atherosclerotic plaques in patients under Statin Therapy. For this purpose, the existing studies focusing on these criteria and the clinical trials and studies have been focused upon. The time frame set for the evaluation of the present literature and findings has been set at the previous decade i.e. the studies of the previous 10 years have been searches through authentic databases and the data related to the current topic has been extracted through efficient sources and reviewers. All the details about MRI efficacy in the assessment of prognosis of Athero…

The electron affinity of astatine

2020

One of the most important properties influencing the chemical behavior of an element is the electron affinity (EA). Among the remaining elements with unknown EA is astatine, where one of its isotopes, 211At, is remarkably well suited for targeted radionuclide therapy of cancer. With the At− anion being involved in many aspects of current astatine labeling protocols, the knowledge of the electron affinity of this element is of prime importance. Here we report the measured value of the EA of astatine to be 2.41578(7) eV. This result is compared to state-of-the-art relativistic quantum mechanical calculations that incorporate both the Breit and the quantum electrodynamics (QED) corrections and…

Therapeutic tools for oral candidiasis : current and new antifungal drugs

2019

Background Candidiasis is one of the most common opportunistic oral infections that presents different acute and chronic clinical presentations with diverse diagnostic and therapeutic approaches. The present study carries out a bibliographic review on the therapeutic tools available against oral candidiasis and their usefulness in each clinical situation. Material and Methods Recent studies on treatment of oral candidiasis were retrieved from PubMed and Cochrane Library. Results Nystatin and miconazole are the most commonly used topical antifungal drugs. Both antifungal drugs are very effective but need a long time of use to eradicate the infection. The pharmacological presentations of mico…

Translational readthrough of ciliopathy genes BBS2 and ALMS1 restores protein, ciliogenesis and function in patient fibroblasts

2021

Abstract Background Ciliary dysfunction underlies a range of genetic disorders collectively termed ciliopathies, for which there are no treatments available. Bardet-Biedl syndrome (BBS) is characterised by multisystemic involvement, including rod-cone dystrophy and renal abnormalities. Together with Alstrom syndrome (AS), they are known as the ‘obesity ciliopathies’ due to their common phenotype. Nonsense mutations are responsible for approximately 11% and 40% of BBS and AS cases, respectively. Translational readthrough inducing drugs (TRIDs) can restore full-length protein bypassing in-frame premature termination codons, and are a potential therapeutic approach for nonsense-mediated ciliop…

Study of leurocyte telomere lenght and transcription in patients in the acute phase of myocardial infarction

2011

Atherosclerosis with cardiovascular complications remains today one of the leading causes of death in developed countries. In this context, development of new biomarkers of atherosclerosis has an important place. Objectives of these biomarkers are: • to identify populations most at risk of developing cardiovascular complications, • to stratify patient groups to optimize their clinical management and therapeutic, • to reveal new therapeutic targets in the treatment of the disease. In this context, we identified three biomarkers of interest, leukocyte telomere length (LTL) and level of expression of leukocyte genes c-Fos (involved in inflammatory processes and oxidative) and OGG1 (necessary r…

Mevolonate Pathway:role of bisphosphonates and statins

2006

Cardiovascular diseases, i.e. high blood pressure, coronary heart disease, and stroke, and osteoporosis are public health problems, with several epidemiological links, and they might be related to each other in terms of pathogenesis and therapeutic agents. Bisphosphonates inhibit bone resorption and are used in the treatment of osteoporosis, whereas statins inhibit cholesterol biosynthesis and are used for the treatment of atherosclerosis and lipid metabolic disorders. Some late clinical studies suggested bisphosphonates may have beneficial effect in vivo on atherosclerotic progression, lipid profiles, and cardiovascular morbidity and mortality, whereas statins might increase bone density, …

Incretin Response to Mixed Meal Challenge in Active Cushing’s Disease and after Pasireotide Therapy

2022

Cushing’s disease (CD) causes diabetes mellitus (DM) through different mechanisms in a significant proportion of patients. Glucose metabolism has rarely been assessed with appropriate testing in CD; we aimed to evaluate hormonal response to a mixed meal tolerance test (MMTT) in CD patients and analyzed the effect of pasireotide (PAS) on glucose homeostasis. To assess gastro-entero-pancreatic hormones response in diabetic (DM+) and non-diabetic (DM–) patients, 26 patients with CD underwent an MMTT. Ten patients were submitted to a second MMTT after two months of PAS 600 µg twice daily. The DM+ group had significantly higher BMI, waist circumference, glycemia, HbA1c, ACTH le…
