New technology was used to identify traces of a commercial barrier/spermicide in evidence from a case of a man accused of rape of a minor. Examination of vaginal swabs performed by another laboratory had been negative for seminal fluid or other sources of DNA from the suspect and we were asked to examine the remaining swabs for any traces that might have originated from the commercial product. ...

BACKGROUND A unified set of criteria for neurocysticercosis (NCC) has helped to standardize its diagnosis in different settings. METHODS Cysticercosis experts were convened to update current diagnostic criteria for NCC according to two principles: neuroimaging studies are essential for diagnosis, and all other information provides indirect evidence favoring the diagnosis. Recent diagnostic ad...

Background & Objective: Dexamethasone has been emerged as an adjuvant to local anesthetics to provide optimal analgesia. We have evaluated the postoperative analgesic efficacy of adding a low dose dexamethasone to bupivacaine in ilioinguinal and iliohypogastric blocks in patients undergoing inguinal herniorraphy under spinal anesthesia. Materials & Methods: 50 patients in the range of 20 - 80 ...

Recently there has been many works on adaptive subspace filtering in the signal processing literature. Most of them are concerned with tracking the signal subspace spanned by the eigenvectors corresponding to the eigenvalues of the covariance matrix of the signal plus noise data. Minor Component Analysis (MCA) is important tool and has a wide application in telecommunications, antenna array pro...

Using a chemical isotope derivative method, we have determined the minor base composition of the "70S-associated" 4S RNA isolated from avian myeloblastosis virus. The minor base composition of this "70S-associated" 4S RNA is strikingly similar to that of the corresponding "free" 4S RNA of the virion. This minor base content, plus the capacity to esterify amino acids, establishes that both of th...

effect of helicobacter pylori eradication or of ranitidine plus metoclopramide on helicobacter pylori-positive and of bismuth or ranitidine plus metoclopramide on helicobacter pylori-negative functional dyspepsia. a  randomized, controlled follow-up study.

Background. Salivary fistula is a common complication after salvage total laryngectomy. Previous studies have not considered the number of layers of pharyngeal closure and have not classified fistulas according to severity. Our objective was to analyze our institutional experience with salvage total laryngectomy, categorize salivary fistulas based on severity, and study the effect of various ph...

BACKGROUND Low postprandial blood glucose is associated with low risk of metabolic diseases. A meal's ability to diminish the glucose response to carbohydrates eaten during the following meal is known as the "second-meal effect" (SME). The reduced glycemia elicited by low-glycemic-index (LGI) foods consumed during the first meal has been suggested as the main mechanism for SME. However, LGI foo...

BACKGROUND: Soil nutrition management is an important factor, which determines the plant growth. Soil fertility is determined by the presence or absence of nutrients i.e. macro and micronutrients, which are required in optimum level for crop. OBJECTIVES: Evaluate the effect different amount of nitrogen and phosphorus fertilizers in maize field under sugarcane ...
