A 37-year-old woman presented with a 3-hour history of back pain, nausea and vomiting and an episode of syncope. A fluid collection in the lesser sac was detected on ultrasound and CT scan. Emergency laparoscopy and subsequent laparotomy were performed and a large blood clot was evacuated from the
Idiopathic spontaneous intraperitoneal hemorrhage (ISIH) is a rare event associated with high mortality. There have been multiple case reports of spontaneous rupture of middle colic pseudoaneurysms in the literature. Herein, we present a case of a 51-year-old female that presented with spontaneous
Mechanical and aerobic energy costs of diving were measured simultaneously by closed-circuit respirometry in six lesser scaup Aythya affinis Eyton (body mass=591±30 g) during bouts of voluntary feeding dives. Durations of dives (td=13.5±1.4 s) and surface intervals (ti=16.3±2.2
This second part of a review of the pharmacologic management of neuropathic pain diseases describes the current treatment options for three lesser-studied neuropathic syndromes: Central poststroke pain, spinal cord injury, and complex regional pain syndrome II. Diagnosis can be difficult in patients
We discuss a self-contained spin-boson model for a measurement-driven engine, in which a demon generates work from thermal excitations of a quantum spin via measurement and feedback control. Instead of granting it full direct access to the spin state and to Landauer's erasure strokes for optimal
Based on a study of the hemodynamics of the greater and pulmonary circulation by direct methods in 117 patients with essential hypertension it has been demonstrated that changes in the stroke volume are implicated in the mechanism of the interregulation of the greater and pulmonary circulation.
OBJECTIVE
Ischemic preconditioning has been well established in healthy human hearts, but limited information is available about its occurrence or its integrity in the brain. The aim of the present study was therefore to investigate whether a prior cerebral ischemic episode (stroke or transient
The shallow, alkaline pan of Lake Nakuru (conductivity 15,000-25,000 μmho/cm, 20°C) usually maintains an exceptionally high standing crop of the cyanophyte Spirulina platensis (150-200 mg DW/l; DW=dry weight), the main food of a large population of the lesser flamingo (Phoeniconaias minor). The
Our experimental study was undertaken to determine the effect of bilateral novocaine vagosympathetic block (VSB) on central hemolymphodynamic and regional hemodinamic in lesser circulation. Follow-up period lasted for 4 hours. No statistically significant arterial pressure changes were detected.
Some cases of thrombi at the ascending and descending aorta have been reported, but there are only a few reports of intraluminal aortic arch thrombi. Most intraluminal thrombi are associated with atherosclerotic lesions at the aortic wall. Here, we report a case of an intraluminal thrombus attached
The metabolic cost of flight increases with mass, so animals that fly tend to exhibit morphological traits that reduce body weight. However, all flying animals must sometimes fly while carrying loads. Load carrying is especially relevant for bats, which experience nightly and seasonal fluctuations
