Hamid Attaran
Methamphetamine is one of the most common abused drugs, so its various effects on different body organs should be familiar to all physicians. Regarding its gastrointestinal sequels, there are few reports of ischemic colitis induced by its vasoconstrictive effects. This is the first report of isolated small intestinal infarction resulting in death following methamphetamine toxicity. A 40-year-old woman with a past history of medical treatment for obesity referred to hospital with severe chest and back pain, perspiration, nausea, agitation, high blood pressure, bradycardia and subsequent lethargy and vasomotor instability...

BACKGROUND: Arginine vasopressin (AVP) is critical for maintaining vasomotor tone and low levels have been associated with the development of irreversible shock. We investigated the clinical relationship between AVP, copeptin (the C-terminal fragment of the AVP precursor), and the development of relative AVP deficiency following hemorrhagic shock. METHODS: A prospective, observational study of 21 hypotensive (SBP<90 mmHg X 2) or presumptively bleeding trauma patients was conducted...

Hemodynamic perturbations, partly resulting from abnormal vasoconstriction of digital vessels, have been implicated in the pathogenesis of bovine and equine laminitis. This study compared the responsiveness of isolated bovine (BDA) and equine (EDA) digital arteries to pharmacological agents that stimulate receptor systems involved in the regulation of normal vessel tone. The role of the endothelium and the short- and longer-term effects of an experimentally induced endothelial damage were also evaluated. Species-related differences were found in the vessel reactivity to all of the receptor agonists tested...

Hypertension is a prevalent pathology that increases risk for numerous cardiovascular diseases. Because the etiology of hypertension varies across patients, specific and effective therapeutic approaches are needed. The role of renal sympathetic nerves is established in numerous forms of hypertension, but their contribution to salt-sensitivity and interaction with factors such as endothelin-1 are poorly understood. Rats deficient of functional ETB receptors (ETB-def) on all tissues except sympathetic nerves are hypertensive and exhibit salt-sensitive increases in blood pressure...

OBJECTIVE: The aim of the study was to compare the effects of different hormone therapies on cardiac repolarization in recently postmenopausal women with and without hot flashes. METHODS: We recruited 150 healthy women: 72 with and 78 without hot flashes. They were randomized and treated for 6 months with transdermal estradiol (1 mg/day), oral estradiol (OE) alone (2 mg/day) or combined with medroxyprogesterone acetate (MPA; 5 mg/day), or placebo. Cardiac repolarization was assessed by measuring QT intervals, rate-dependence of QT-end interval, and T waves from 24-hour electrocardiographic recording before and during hormone therapy, comprising a total of over 20 million QT-interval measurements...

Sympathetic vasomotor activity is significantly increased in renovascular hypertension. Renal denervation (DnX) has emerged as a novel therapy for resistant hypertension to drug therapy. However, the underlying mechanisms regarding the reduction in blood pressure (BP) after DnX remain unclear. Thus, the aim of this study was to evaluate the effects of DnX of a clipped kidney on the baseline and baroreceptor reflex control of post-ganglionic sympathetic activity to the contralateral kidney (rSNA) and lumbar (lSNA) nerves in Goldblatt hypertensive rats (2K1C)...

Nitric oxide (NO) has emerged as a potent effector molecule for a post-resuscitation disease as a result of the low-energy defibrillation. In this article, the authors anlysed the changes of endogenous nitric oxide levels in serum of 35 healthy rabbits after the transthoracic application of low-energy two-phase shock impulse. The animals were randomised into four groups according to the electrical energy dose to be applied during the experiment. Life parameters of the animals were monitored using the BeneViev T5 patient monitor...

BACKGROUND: The prevalence of menopause in women with or at risk of chronic kidney disease is increasing globally. Although international guidelines on menopause recommend the use of postmenopausal hormone therapy with or without selective estrogen receptor modulators for control of vasomotor symptoms, the effects of these treatments on kidney function and albuminuria are unclear. Furthermore, women with chronic kidney disease are at significantly increased risk of venous thromboembolism and malignancy, well-documented adverse effects of postmenopausal hormone therapy...

Adequate blood flow is essential to brain function and its disruption is an early indicator in diseases like stroke and diabetes. However, the mechanisms contributing to this impairment remain unclear. To address this gap, in the diabetic and nondiabetic male mouse retina we combined an unbiased longitudinal assessment of vasomotor activity along a genetically defined vascular network with pharmacological and immunohistochemical analyses of pericytes, the capillary vasomotor elements. In nondiabetic retina, focal stimulation of a pericyte produced a robust vasomotor response, which propagated along the blood vessel with increasing stimulus...

Vitamin C (vitC) deficiency is associated with increased cardiovascular disease risk, but its specific interplay with arteriolar function is unclear. This study investigates the effect of vitC deficiency in guinea pigs on plasma biopterin status and the vasomotor responses in coronary arteries exposed to vasoconstrictor/-dilator agents. Dunkin Hartley female guinea pigs (n = 32) were randomized to high (1500 mg/kg diet) or low (0 to 50 mg/kg diet) vitC for 10-12 weeks. At euthanasia, coronary artery segments were dissected and mounted in a wire-myograph...

Endothelial-mediated mechanisms that regulate skin blood flow may play an integral role in optimizing skin perfusion in vascular beds with sympathetic nervous system vasomotor impairment, such as in spinal cord injury (SCI). Insulin is a vasoactive hormone and second messenger of nitric oxide that facilitates endothelial-mediated dilatation. The effects of insulin resistance (IR) on sublesional cutaneous perfusion responses to insulin provocation have yet to be described in persons with SCI. Persons with SCI and an able-bodied (AB) cohort were divided into subgroups based upon fasting plasma insulin (FPI) concentration cut-offs for IR (≥13...

Prostate cancer is the second most commonly diagnosed cancer in men. Conventional endocrine treatment for prostate cancer leads to global sex steroid deprivation. The ensuing severe hypogonadism is associated with well-documented adverse effects. Recently it has become apparent that many of the biological actions attributed to androgens in men are in fact not direct, but mediated by estradiol. Available evidence supports a primary role for estradiol in vasomotor stability, skeletal maturation and maintenance, and prevention of fat accumulation...

Females are typically more insulin sensitive than males which may be partly attributed to greater brown adipose tissue (BAT) activity and uncoupling protein 1 (UCP1) content. Accordingly, we tested the hypothesis that UCP1 deletion would abolish sex differences in insulin sensitivity and that whitening of thoracic periaortic BAT caused by UCP1 loss would be accompanied with impaired thoracic aortic function. Furthermore, because UCP1 exerts antioxidant effects, we examined whether UCP1 deficiency-induced metabolic dysfunction was mediated by oxidative stress...
