Three millilitres of plain 0.5% bupivacaine were injected intrathecally at two different spinal interspaces (L2/3 and L4/5) and at two different speeds (15 and 30 sec) in four groups of ten patients. Injection at L2/3 over 15 sec produced a significantly higher mean maximum spread of analgesia (T6.4) when compared to injection at L4-5 over 15 sec (T10.3) (P < 0.05). Over the same interspace L2/...

This paper introduces the R package edgar to download and analyze Securities Exchange Commission’s (SEC) mandatory public disclosures in United States. Corporations U.S. submit their periodic reports, registration statements, financial reports electronically SEC. The SEC makes these publicly accessible everyone through Electronic Data Gathering, Analysis, Retrieval System (EDGAR). As reporting ...

Approximately 50% of total harvested cereal grains are lost during the post-harvest handling and storage, insects main cause for both quantity (reductions in weight) quality. In present study effect microwave radiation was studied on one stored product pest, flour beetle Tribolium castaneum (Hersbt). Adult were obtained from infested products at stores specialized selling Sakaka. Insects with i...

BACKGROUND Fluoroscopy time (FT) in endoscopic retrograde cholangiopancreatography (ERCP) has a linear relationship with radiation exposure to endoscopist, personnel and patients. The aim of this prospective study was to investigate the factors influencing the FT during ERCP. PATIENTS AND METHODS Between January 2010 and August 2011, patients with naïve papilla undergoing therapeutic ERCP wer...

Expression of the staphylococcal enterotoxin type C gene (sec) is regulated in response to both high NaCl concentrations (osmolarity) and the accessory gene regulator (agr). agr is a global regulator that alters the expression of many genes in Staphylococcus aureus. In this report, we have demonstrated that osmoregulation of sec occurs at the level of mRNA independently of an intact agr allele....

Selenocysteine (Sec) is naturally incorporated into proteins by recoding the stop codon UGA. Sec is not hardwired to UGA, as the Sec insertion machinery was found to be able to site-specifically incorporate Sec directed by 58 of the 64 codons. For 15 sense codons, complete conversion of the codon meaning from canonical amino acid (AA) to Sec was observed along with a tenfold increase in selenop...

&lt;sec&gt;In the last two years, discrete memristor has been proposed, and it is in early stages of research. Now, particularly important to use various simulation softwares expand applications model. Based on difference operator, this paper, a model with quadratic nonlinearity constructed. The addition, subtraction, multiplication division mathematical are clarified, charge &lt;i&gt;q&lt;/i&g...

background: myocardial ischemia is one of several causes of prolonged qt dispersion. the aim of this study was to evaluate the effect that percutaneous coronary intervention has on the depolarization and repolarization parameters of surface electrocardiography in patients with chronic stable angina. methods: we assessed the effects of full revascularization in patients with chronic stable angin...

conclusions s. aureus can easily contaminate the chicken nugget and this contamination is usually associated with significant presences of virulence genes. consumption of these nuggets certainly is associated with gastrointestinal diseases. therefore, some food safety and quality standards should be applied and performed in most of the iranian food units to control growth of s. aureus and its v...
