Androgens are vasoactive steroids that induce acute vasodilation in a number of isolated vascular beds from different species, but the effects of these hormones on systemic blood pressure (BP) have been studied little. Although it has been reported that androgens exert systemic hypotensive effects through peripheral vasodilation in normotensive rats, there have not been any reports of systemic hypotensive effects of androgens in animals with hypertension. This study was designed to evaluate the acute effects of testosterone (TES) and its 5-reduced metabolites on systemic BP in hypertensive rats and to test the hypothesis that hypotestosteronemia may be involved in the pathogenesis of hypertension...

BACKGROUND: Terminal extubation (TE) is applied in some intensive care unit (ICU) patients when a decision of withdrawal of mechanical ventilation is decided. Other units prefer terminal weaning (TW) with no removal of the endotracheal tube. We report our experience with these two procedures. METHODS: We conducted a retrospective study analyzing patients deceased in our ICU after a decision of life sustained therapy (LST) during the year 2013. TE was proposed to family members for patients presenting with two medical conditions: lack of vasoactive drugs (VAD) and SaO2 > 95% with a FIO2 < 50%...

We previously demonstrated that the typical mitochondrial uncoupler carbonyl cyanide m-chlorophenylhydrazone (CCCP) inhibited artery constriction, but CCCP was used only as a pharmacological tool. Niclosamide is an anthelmintic drug approved by FDA. Niclosamide ethanolamine (NEN) is a salt form of niclosamide and has been demonstrated to uncouple mitochondrial oxidative phosphorylation. The aim of the present study was to elucidate the vasoactivity of NEN and the potential mechanisms. Isometric tension of rat mesenteric artery and thoracic aorta was recorded by using multi-wire myograph system...

Background: Approximately 60% of patients experience moderate-to-severe pain after neurosurgery, which primarily occurs in the first 24-72 h. Despite this, improved postoperative analgesia solutions after neurosurgery have not yet been devised. This retrospective study was conducted to evaluate the effect of intra- and post-operative infusions of dexmedetomidine (DEX) plus sufentanil on the quality of postoperative analgesia in patients undergoing neurosurgery. Methods: One hundred and sixty-three post-neurosurgery patients were divided into two groups: Group D (DEX infusion at 0...

The case fatality rate of infective endocarditis (IE) is high and is associated with varying causes. Among them, acute myocardial infarction due to an embolism in a coronary artery is rare; the incidence of this complication in the setting of IE is reported to be up to 1.5%. We report a case of sudden death in a 22-year-old woman diagnosed with systemic lupus erythematosus who was referred to the Cardiology Center for the treatment of mitral valve incompetence due to IE. She was hemodynamically stable with antibiotic therapy and vasoactive drugs, despite severe mitral valve regurgitation...

BACKGROUND: Vascular depression is regarded as a subtype of late-life depression characterized by a distinct clinical presentation and an association with cerebrovascular damage. Although the term is commonly used in research settings, widely accepted diagnostic criteria are lacking and vascular depression is absent from formal psychiatric manuals such as the Diagnostic and Statistical Manual of Mental Disorders, 5(th) edition - a fact that limits its use in clinical settings. Magnetic resonance imaging (MRI) techniques, showing a variety of cerebrovascular lesions, including extensive white matter hyperintensities, subcortical microvascular lesions, lacunes, and microinfarcts, in patients with late life depression, led to the introduction of the term "MRI-defined vascular depression"...

BACKGROUND AND PURPOSE: Propranolol is a vasoactive drug that shows antiangiogenic and antitumour activities in melanoma. However, it is unknown whether these activities are dose-dependent and whether there is a relationship between systemic vascular effects of propranolol and anti-melanoma activity. EXPERIMENTAL APPROACH: Effects of increasing doses of propranolol (10, 20, 30 and 40 mg·kg(-1) ·day(-1) ) on tumour growth were studied in B16F10 melanoma-bearing mice...

Resiniferatoxin (RTX) is used as experimental drug therapy for a range of neurogenic urinary bladder disorders. The present study investigated the chemical coding of caudal mesenteric ganglion (CaMG) neurons supplying the porcine urinary bladder after intravesical RTX instillation. The CaMG neurons were visualized with retrograde tracer Fast Blue (FB) and their chemical profile was disclosed with double-labelling immunohistochemistry using antibodies against tyrosine hydroxylase (TH), neuropeptide Y (NPY), vasoactive intestinal polypeptide (VIP), somatostatin (SOM), calbindin (CB), galanin (GAL) and neuronal nitric oxide synthase (nNOS)...

Asthma is a chronic respiratory disease characterized by airway inflammation, bronchoconstriction, airway hyperresponsiveness and recurring attacks of impaired breathing. Vasoactive intestinal peptide (VIP) has been proposed as a novel anti-asthma drug due to its effects on airway smooth muscle relaxation, bronchodilation and vasodilation along with its immunomodulatory and anti-inflammatory properties. In the current study, we investigated the therapeutic effects of VIP when conjugated with α-alumina nanoparticle (α-AN) to prevent enzymatic degradation of VIP in the respiratory tract...

The burden of cardiovascular diseases (CVD) in general and heart failure (HF) in particular continues to increase worldwide. CVD are major contributors to death and morbidity and recognized as important drivers of healthcare expenditure. Chronic overactivity of the renin-angiotensin-aldosterone system (RAAS) plays a key role in human hypertension and HF pathophysiology. RAAS is fundamental in the overall regulation of cardiovascular homeostasis through the actions of hormones, which regulate vascular tone, and specifically blood pressure through vasoconstriction and renal sodium and water retention...

OBJECTIVE: Voltage-dependent calcium channels (VDCCs) play an important role in two major abnormalities observed in spontaneously hypertensive rats (SHR) - hyperactivity of sympathetic nervous system (SNS) and enhanced Ca influx to vascular smooth muscle cells (VSMC). α2δ subunit of VDCC, which promotes surface trafficking and modulates the biophysical properties of VDCC, was identified as a critical component of increased L-type VDCC calcium currents in arterial myocytes of SHR. On the other hand, N-type VDCCs control a neurotransmitter release in the peripheral sympathetic nervous system and play an important role in sympathetic hyperactivity in SHR...

OBJECTIVE: Neurosurgery in general anesthesia exposes patient to hemodynamic alternations both in prone and sitting position. As the comparison of the sitting and prone position in neurosurgery is scarce, we aimed to evaluate hemodynamic profile during stroke volume-directed fluid administration in patients undergoing neurosurgery either in sitting or prone position. METHODS: Thirty patients in prone and 28 in sitting position in two separate prospective trials were randomized to receive either Ringer's Acetate (RAC) or hydroxyethyl starch (HES 130 kDa/0...

BACKGROUND: One of the main postoperative complications of kidney transplant is delayed graft function (DGF), which means absence of graft function after transplant or the need for dialysis during the first week post procedure. The occurrence of DGF currently in our hospital is high and has been attributed to a combination of many factors. The aim of this study was to evaluate the factors associated to DGF and their influence in the outcome of kidney transplants. METHODS: Historical cohort of 150 patients transplanted with live or deceased donor kidneys from 2011 to 2013...
