Abstract:

Acute mesenteric ischemia, caused by an abrupt interruption of blood flow in the mesenteric vessels, is associated with high mortality. When treated with surgical interventions or drugs to re-open the vascular lumen, the reperfusion process itself can inflict damage to the intestinal wall. Ischemia and reperfusion injury comprise complex mechanisms involving disarrangement of the splanchnic microcirculatory flow and impairment of the mitochondrial respiratory chain due to initial hypoxemia and subsequent oxidative stress during the reperfusion phase. This pathophysiologic process results in th

Abstract:

Clinical and experimental studies have shown that trauma combined with hemorrhage shock (T/HS) is associated with myocardial contractile dysfunction. However, the initial events triggering the cardiac dysfunction are not fully elucidated. Thus we tested the hypothesis that factors carried in intestinal (mesenteric) lymph contribute to negative inotropic effects in rats subjected to a laparotomy (T) plus hemorrhagic shock (HS; mean arterial blood pressure of 30–40 Torr for 90 min) using a Langendorff isolated heart preparation. Left ventricular (LV) function was assessed 24 h after trauma plus

Abstract:

Acute β-blockade with metoprolol has been associated with increased mortality by undefined mechanisms. Since metoprolol is a relatively high affinity blocker of β2-adrenoreceptors, we hypothesized that some of the increased mortality associated with its use may be due to its abrogation of β2-adrenoreceptor-mediated vasodilation of microvessels in different vascular beds. Cardiac output (CO; pressure volume loops), mean arterial pressure (MAP), relative cerebral blood flow (rCBF; laser Doppler), and microvascular brain tissue Po2 (G2 oxyphor) were measured in anesthetized mice before and after

Abstract:

Mesenteric ischemia is caused by a reduction in mesenteric blood flow. It can be divided into acute and chronic, based upon the rapidity and the degree to which the blood flow is compromised. The authors retrospectively reviewed 22 cases of mesenteric ischemia, diagnosed by multidetector computed tomography (MDCT) in our service, and confirmed by surgery or clinical follow-up. The frequency of the diagnostic findings of chronic and acute mesenteric ischemia was evaluated. The improvement of three-dimensional (3D) MDCT allows accurate assessment of mesenteric vessels. Therefore, it demonstrates

Abstract:

Introduction: Acute mesenteric ischemia/occlusion is a life-threatening vascular emergency that requires early diagnosis and intervention to restore mesenteric blood flow and to prevent loss of life. Despite progress in our understanding about the mesenteric ischemia, diagnostic modalities, and treatment options, the mesenteric ischemia remains a diagnostic challenge. This leads to delayed implementation of treatment and thus contributes to high mortality and morbidity. Methods: Here, we have presented a case report of superior mesenteric artery thrombosis. It discusses the various aspects of

Abstract:

Previous studies have shown that renal autoregulation dynamically stabilizes renal blood flow (RBF). The role of renal nerves, particularly of a baroreflex component, in dynamic regulation of RBF remains unclear. The relative roles of autoregulation and mesenteric nerves in dynamic regulation of blood flow in the superior mesenteric artery (MBF) are similarly unclear. In this study, transfer function analysis was used to identify autoregulatory and baroreflex components in the dynamic regulation of RBF and MBF in Wistar rats and young spontaneously hypertensive rats (SHR) anesthetized with iso

Abstract Stroke is defined as the acute onset of a non-convulsive, neurologic deficit that is caused by a disturbance of the cerebral circulation. It is the most common neurologic disorder and the most common cause of brain lesions. The signs and symptoms of stroke vary widely from person to person, however, in all strokes the neurologic deficit has an abrupt onset. Stroke is due to either ischemia (i.e., a loss of blood flow to a focal area of neural tissue) or hemorrhage (i.e., rupture of a blood vessel and bleeding).

Abstract:

Abstract Mesenteric ischemia (MI) includes several clinical conditions that occur when splanchnic blood flow is inadequate and thus fails to meet the metabolic demands of the intestines. The condition can result in symptomatic and life-threatening clinical presentations. The incidence of MI is increasing because of the aging population, increasing number of critically ill patients, and heightened clinical awareness. MI produces a spectrum of disorders that depend on many factors, including the acuity of the event, the vessel involved, and the length of bowel affected. In general, MI can be div

To examine whether spontaneous autoregulatory responses of the arterial vasculature can contribute to the short-term variability of arterial pressure (AP), rats were chronically instrumented for the simultaneous measurement in the conscious State of AP and of either cardiac output, mesenteric or hindquarters blood flow. Acute pharmacological removal of neurohumoral influences induced a marked increase in AP variability when the AP level was maintained with a continuous noradrenaline infusion. AP lability was especially due to the spontaneous occurrence of large depressor episodes that were acc

Abstract:

Hepatorenal Syndrome (HRS) is an important condition for clinicians to be aware of in the presence of cirrhosis. In simple terms, HRS is defined as a relative rise in creatinine and relative drop in serum glomerular filtration rate (GFR) alongside renal plasma flow (RPF) in the absence of other competing etiologies of acute kidney injury (AKI) in patients with hepatic cirrhosis. It represents the end stage complication of decompensated cirrhosis in the presence of severe portal hypertension, in the absence of prerenal azotemia, acute tubular necrosis or others. It is a diagnosis of exclusion.

Abstract:

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare and progressive pulmonary vascular disease that is usually the consequence of prior acute pulmonary embolism. CTEPH usually begins with persistent obstruction of large and/or middle-sized pulmonary arteries by organized thrombi. Failure of thrombi to resolve may be related to abnormal fibrinolysis, and underlying haematological or autoimmune disorders, including splenectomy and antiphospholipid antibodies. Small pulmonary vessel remodelling also contributes to haemodynamic compromise, functional impairment, and disease progression

Pulmonary illnesses like asthma and CF can have direct impacts on brain functioning through systemic hypoxia (low blood oxygen [O2] level) or hypercapnia (high blood carbon dioxide [CO2] level) due to poor respiratory gas exchange.

Abstract:

Pulmonary arterial hypertension (PAH) is a devastating disease exhibiting fast progression [1] and poor prognosis [2]. PAH originates from an increased resistance to blood flow in the distal pulmonary vasculature and in the later stages of the disease leads to right ventricular (RV) functional impairment and subsequent heart failure, which in most cases is the direct cause of demise. In PAH, RV failure appears to be correlated to PA stiffening, which is a better predictor of mortality than the direct increases in mean pulmonary arterial pressure (mPAP) and pulmonary vasculature resistance (PVR

Thus, in order to predict the efficacy of E-5510 in thrombotic disorders, the anti-thrombotic effects were examined in 3 different animal models of thrombosis.(1) Anti-thrombotic effect in an extracorporeal shunt model Two hrs after oral administration
