This paper presents an Ultra-Short Baseline (USBL) and Inertial Navigation System (INS) integration technique to enhance position and orientation estimates of underwater vehicles. Two closed-form methods for the computation of the position of aiding transponders are presented and compared, exploiting the planar approximation of the acoustic waves or considering the distances between the transpo...

INTRODUCTION Basidiobolomycosis is an unusual fungal disease that rarely involves the visceral organs such as gastrointestinal tract. Gastrointestinal basidiobolomycosis (GIB) has been increasingly reported in the literature, and it is an emerging disease from arid regions worldwide, in particular, the south-western Saudi Arabia. We report a case of GIB in a 36-year-old Saudi Arabian male patie...

This paper explores a novel approach for the extraction of relevant information in speaker recognition tasks. This approach uses a principled information theoretic framework the Information Bottleneck method (IB). In our application, the method compresses the acoustic data while preserving mostly the relevant information for speaker identification. This paper focuses on a continuous version of ...

Continuous-flow left ventricular assist device (CF-LVAD) insertion is a life-saving procedure that is being increasingly used in patients with advanced heart failure. However, patients with CF-LVADs are at an increased risk of gastrointestinal bleeding (GIB). Bleeding can occur anywhere in the GI tract with lesions being more prevalent in the upper GI tract than in the lower GI tract. The patho...

Hemospray (Cook Medical, Winston-Salem, North Carolina, USA) is a hemostatic agent recently introduced for the management of upper gastrointestinal bleeding (GIB). To date, there is little experience with this fairly new hemostatic tool. The aim of this case series was to reflect the use and effectiveness of Hemospray as a treatment option in GIB in everyday clinical practice at two tertiary re...

Sialic acid binding lectin (SBL) isolated from Rana catesbeiana oocytes is a multifunctional protein which has lectin activity, ribonuclease activity and antitumor activity. However, the mechanism of antitumor effects of SBL is unclear to date and the validity for human leukemia cells has not been fully studied. We report here that SBL shows cytotoxicity for some human leukemia cell lines inclu...

OBJECTIVE To determine whether aspirin plus a proton pump inhibitor (PPI) is preferable, from a gastrointestinal bleed (GIB) risk perspective, to clopidogrel in patients who have experienced a GIB while on aspirin and who require single antiplatelet therapy for secondary prevention of cardiovascular disease. DATA SOURCES A literature search was conducted using EMBASE (1980-January 2008), PubM...

OBJECTIVE We assessed gastrointestinal bleeding (GIB) and cardiovascular (CV) risks such as myocardial infarction or stroke associated with non-steroidal anti-inflammatory drug (NSAID) use among elderly patients with diabetes. METHODS Using a nationwide claims database covering 2008-2012, we conducted a cohort study of patients with diabetes aged ≥65 years. Among the 117 610 patients, NSAID u...

INTRODUCTION Patients with severe brain lesions (SBL) and brain-dead patients (BD) frequently present with vasopressin (AVP) secretion disorders. OBJECTIVE To evaluate AVP serum levels in SBL and BD patients. DESIGN Prospective, open label, observational trial. SETTING A general teaching hospital. METHOD Three groups of adult subjects (age> 18y) of both sexes were included in this study...

When the sensory block level (SBL) is ≥T5 or T4, a high incidence of hypotension occurs in parturients after spinal anesthesia. A rapidly ascending SBL is another risk factor for spinal anesthesia-induced hypotension. However, the relationship between the ascension rate of the SBL and spinal anesthesia-induced hypotension remains unclear.After placement in the left lateral position, combined ep...
