"To B or Not to B"…That Is the Question: Whether We Can Identify Those at Risk for Cardiac Dysfunction During Cancer Therapy.

Treg cells depletion is a mechanism that drives microvascular dysfunction in mice with established hypertension.

Microvascular dysfunction is a major complication in hypertensive patients. We previously reported that CD4CD25 T regulatory cells (Treg) play an important preventive role in hypertension-induced vascular dysfunction. However, whether Treg cells therapy and autophagy inhibition could rescue Treg cells survival and microvascular function in established hypertension is an important question that rem...

Th1 type immune responses to Porphyromonas gingivalis antigens exacerbate Angiotensin II dependent hypertension and vascular dysfunction.

Emerging evidence indicates that hypertension is mediated by immune mechanisms. We hypothesized that exposure to Porphyromonas gingivalis antigens, commonly encountered in periodontal disease, can enhance immune activation in hypertension and exacerbate blood pressure elevation, vascular inflammation and vascular dysfunction.

Increased SOD2 in the diaphragm contributes to exercise-induced protection against ventilator-induced diaphragm dysfunction.

Mechanical ventilation (MV) is a life-saving intervention for many critically ill patients. Unfortunately, prolonged MV results in rapid diaphragmatic atrophy and contractile dysfunction, collectively termed ventilator-induced diaphragm dysfunction (VIDD). Recent evidence reveals that endurance exercise training, performed prior to MV, protects the diaphragm against VIDD. While the mechanism(s) re...

Right ventricular dysfunction and remodeling in diabetic cardiomyopathy.

The increasing prevalence of diabetic cardiomyopathy (DCM) is an important threat to health world-wide. While left ventricular (LV) dysfunction in DCM is well recognized, the accurate detection, diagnosis, and treatment of changes in right ventricular (RV) structure and function have not been well characterized to date. The pathophysiology of RV dysfunction in DCM may share features with LV diasto...

Monomethyl fumarate alleviates sepsis-induced hepatic dysfunction by regulating TLR-4/NF-κB signalling pathway.

Sepsis is a potentially fatal illness that can lead to impairment of multiple organs such as liver. The condition is deeply associated with oxidative stress and inflammation. Monomethyl fumarate (MMF) has manifested antioxidant and immunomodulatory properties. The aim of current study was to evaluate protective effects of MMF in sepsis-induced hepatic dysfunction.

Incidence, Predictors, and Outcomes of New Onset Left Ventricular Systolic Dysfunction after Orthotopic Liver Transplantation.

Adverse cardiovascular events after liver transplant (LT) are relatively common and are a significant source of early mortality. Although new onset systolic dysfunction after LT is a reported phenomenon, there is little data regarding its incidence, risk factors, and outcomes.

Eustachian tube dysfunction: A diagnostic accuracy study and proposed diagnostic pathway.

Eustachian tube dysfunction (ETD) is a commonly diagnosed disorder of Eustachian tube opening and closure, which may be associated with severe symptoms and middle ear disease. Currently the diagnosis of obstructive and patulous forms of ETD is primarily based on non-specific symptoms or examination findings, rather than measurement of the underlying function of the Eustachian tube. This has proved...

Mitochondrial dysfunction and oxidative stress in induced pluripotent stem cell models of Parkinson's disease.

Parkinson's disease (PD) is the second most common neurodegenerative disease. 2% of the population above the age of 60 is affected by the disease. The pathological hallmarks of PD include loss of dopaminergic neurons and the presence of Lewy bodies. Mitochondrial dysfunction and oxidative stress are thought to play a pivotal role in both sporadic and familial forms of the disease. In this review w...

Mitochondrial dysfunction and gut microbiota imbalance: An intriguing relationship in chronic kidney disease.

Pulse Waveform Analysis in Ocular Microcirculation by Laser Speckle Flowgraphy in Patients with Left Ventricular Systolic and Diastolic Dysfunction.

To determine: (1) whether variables of a pulse wave form analysis of ocular microcirculation shown by laser speckle flowgraphy (LSFG) correlate with left ventricular (LV) systolic dysfunction and (2) whether these variables correlate with LV diastolic dysfunction in subjects without LV systolic dysfunction as assessed by echocardiography.

Lateral orbitofrontal dysfunction in the Sapap3 knockout mouse model of obsessive–compulsive disorder

Obsessive–compulsive disorder (OCD) is a common psychiatric disorder that affects about 2% of the population, but the underlying neuropathophysiology of OCD is not well understood. Although increasing lines of evidence implicate dysfunction of the orbitofrontal cortex (OFC) in OCD, a detailed understanding of the functional alterations in different neuronal types in the OFC is still elusive.

Metabolic resuscitation strategies to prevent organ dysfunction in sepsis.

Sepsis is the main cause of death among patients admitted to the intensive care unit (ICU). As current treatment is limited to antimicrobial therapy and supportive care, mortality remains high, which warrants efforts to find novel therapies. Mitochondrial dysfunction is emerging as a key process in the induction of organ dysfunction during sepsis and metabolic resuscitation might reveal to be a no...

Limited Impact of β-Adrenergic Receptor Activation on Left Ventricular Diastolic Function in Rat Models of Hypertensive Heart Disease.

Hypertension is a major cause of left ventricular (LV) diastolic dysfunction. Although β-adrenergic receptor (β-AR) blockers are often used to manage hypertension, the impact of β-AR activation on LV lusitropic effects and hence filling pressures in the hypertensive heart with LV diastolic dysfunction is uncertain.

Hydroxychloroquine partially prevents endothelial dysfunction induced by anti-beta-2-GPI antibodies in an in vivo mouse model of antiphospholipid syndrome.

Antiphospholipid syndrome is associated with endothelial dysfunction, which leads to thrombosis and early atheroma. Given that hydroxychloroquine has anti-thrombotic properties in lupus, we hypothesized that it could reduce endothelial dysfunction in an animal model of antiphospholipid syndrome. We evaluated the effect of hydroxychloroquine in preventing endothelial dysfunction in a mouse model of...

Men's health 2018: BPH, prostate cancer, erectile dysfunction, supplements.

This review describes the latest research and guidelines for 4 topics in men's health commonly addressed by primary care physicians: the diagnosis and treatment of benign prostatic hyperplasia (BPH), prostate cancer, and erectile dysfunction and the evidence concerning the use of dietary supplements in men.

Effect of Vitamin D Therapy on Sexual Function in Women with Sexual Dysfunction and Vitamin D Deficiency: a Randomized, Double-blind, Placebo-controlled Clinical Trial.

To investigate the effect of vitamin D therapy on sexual function in women with low vitamin D levels and sexual dysfunction.

Executive control dysfunction in subclinical depressive undergraduates: Evidence from the Attention Network Test.

It has been proposed that depressed individuals have broad neuropsychological dysfunction, particularly in the executive control domain. The Attention Network Test (ANT) is widely used to assess the efficiency of three attention networks: alerting, orienting, and executive control. In the present study, we investigated the behavioral and event-related potential (ERP) indicators of attention proces...

Efficacy and safety of PDE5 inhibitors in the treatment of diabetes mellitus erectile dysfunction: Protocol for a systematic review: Erratum.

Biodynamics: A novel quasi-first principles theory on the fundamental mechanisms of cellular function/dysfunction and the pharmacological modulation thereof.

Cellular function depends on heterogeneous dynamic intra-, inter-, and supramolecular structure-function relationships. However, the specific mechanisms by which cellular function is transduced from molecular systems, and by which cellular dysfunction arises from molecular dysfunction are poorly understood. We proposed previously that cellular function manifests as a molecular form of analog compu...

Association between systemic lupus erythematosus and thyroid dysfunction: a meta-analysis.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease, the pathogenesis of which remains elusive. The deficiency or excess of thyroid hormone is defined as thyroid dysfunction, including (subclinical) hypothyroidism and (subclinical) hyperthyroidism. Autoimmune factors are likely to be relevant to the development of SLE and thyroid dysfunction. Recently, many studies have indicated th...

Assessing the feasibility of using the Dalhousie Computerized Attention Battery to measure postoperative cognitive dysfunction in older patients.

Postoperative cognitive dysfunction is difficult to predict and diagnose, and can have severe consequences in the long term. The purpose of our study was to examine the feasibility of using a computerised test battery, the Dalhousie Computerized Assessment Battery in the perioperative clinic to detect cognitive changes after surgery.

Urinary Microbiome Associated with Chronic Allograft Dysfunction in Kidney Transplant Recipients.
