Diagnostic yield of small histological cores obtained with a new EUS-guided fine needle biopsy system.

Background: As endoscopic ultrasound-guided tissue acquisition techniques evolve, there is increasing interest in obtaining optimal histological samples to improve diagnostic accuracy. In this study, we aimed to assess the tissue acquisition success rate and test performance characteristics of a novel endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) system.

Methods: We performed a retrospective review of consecutive patients undergoing EUS-guided tissue sampling of solid lesions using the SharkCore fine needle system in a tertiary referral facility.

Prevalence of vitamin D deficiency and response to oral vitamin D supplementation in patients receiving home parenteral nutrition.

Unlabelled: The purpose of this study was to document vitamin D status in home parenteral nutrition (HPN) patients and determine if oral vitamin D supplementation has a substantial effect.

Methods: A retrospective chart review of eligible adults enrolled in the Southern Alberta Home Parenteral Nutrition program (n = 15) for a minimum of 6 months was conducted. Serum measurements of 25OHD were recorded and patients were categorized by vitamin D status as follows: sufficient; insufficient; deficient with respective levels of 25OHD ≥75 nmol/L, 27.

Hyperglycemia in hospitalized patients receiving parental nutrition is associated with increased morbidity and mortality: a review.

Parenteral Nutrition (PN) is a valuable life saving intervention which can improve the nutritional status of hospitalized malnourished patients. PN is associated with complications including the development of hyperglycemia. This paper aims to provide a descriptive systematic review regarding the effects of PN-induced hyperglycemia in hospitalized patients, either in the intensive care unit or ward, while formulating and complementing existing guidelines on the administration of PN and glucose monitoring in hospitalized patients.

Distinct regulatory role for RFL, the rice LFY homolog, in determining flowering time and plant architecture.

Activity of axillary meristems dictates the architecture of both vegetative and reproductive parts of a plant. In Arabidopsis thaliana, a model eudicot species, the transcription factor LFY confers a floral fate to new meristems arising from the periphery of the reproductive shoot apex. Diverse orthologous LFY genes regulate vegetative-to-reproductive phase transition when expressed in Arabidopsis, a property not shared by RFL, the homolog in the agronomically important grass, rice.

Impairment of metabolic capacities in copper and calcium contaminated wild yellow perch (Perca flavescens).

This study examined variations in resting oxygen consumption rate (ROCR), post-exercise oxygen consumption rate, relative scope for activity (RSA), liver and muscle aerobic and anaerobic capacities (using citrate synthase (CS) and lactate dehydrogenase, respectively, as indicators), and tissue biosynthetic capacities (using nucleoside diphosphate kinase (NDPK) as an indicator), in wild yellow perch from four lakes varying in copper (Cu) and cadmium (Cd) contamination. Liver Cu and Cd concentrations largely reflected environmental contamination and were positively correlated with liver protein concentrations and NDPK activities. Our results suggest that metal contamination leads to an upregulation of liver protein metabolism, presumably at least in part for the purpose of metal detoxification.
