Validation of oblique line contrast (W-index) for osteoporosis risk screening in panoramic radiographs using peripheral dual-energy X-ray absorptiometry.

The objective of this study was to validate the usefulness of the W-index (WI) for screening patients at risk of osteoporosis by correlating the WI results with those obtained from peripheral dual-energy X-ray absorptiometry (pDXA). The W-index is based on oblique line contrast on panoramic radiographs, in which the pixel intensity of the oblique line is compared with the pixel intensity of adjacent structures at the mandibular ramus. A total of 333 patients with panoramic radiographs and pDXA results were evaluated according to T-score results and WI measurements.

Mandibular Bone Imaging Assessment in Individuals With Rheumatoid Arthritis: A Comparative Cross-Sectional Study.

Objective: To assess the risk of low bone mineral density (BMD), evaluated by mandibular cortical index (MCI), W-index (WI), and the continuity of the mandibular canal cortices in rheumatoid arthritis (RA) patients in comparison with healthy subjects.

Material And Methods: A retrospective and comparative study was conducted in individuals diagnosed with rheumatoid arthritis (Study Group-SG) and healthy individuals without comorbidities (Control Group-CG). MCI, WI, and the continuity of the mandibular canal cortices were evaluated by two experienced observers.

Beta-glucans supplementation for sows during gestation and lactation.

Purpose: The aim of the present study was to evaluate the effects of dietary beta-glucans supplementation for gestation and lactation sows of 1st, 2nd or 3rd parity on sows and litters performance, milk composition and Brix value of colostrum, hemogram and serum immunoglobulin G concentration of sows and piglets.

Methods: A total of 78 sows were distributed in a completely randomized design, in a 2x3 factorial scheme, with two supplementation levels (0 and 450 mg/kg of beta-glucans) and three parities (1st, 2nd or 3rd).

Results: No interaction was observed between supplementation and parturition for any of the analyzed variables.

Structured lipids from fish viscera and coconut oils improve weight gain and intestinal morphology of piglets at nursery phase.

Five metabolism assays were performed to determine the metabolizable energy (ME) content of soybean oil, coconut oil, fish viscera oil, physical mixture of coconut oil and fish viscera oil (3:2, in kg: kg) and structured lipid prepared from interesterification of fish viscera oil and coconut oil (3: 2, in kg: kg), and one assay to evaluate the effects of including these lipid sources in piglet diets on performance, digestibility of diets, incidence of diarrhea and intestinal morphometry at nursery phase. Soybean, coconut, fish viscera, physical mixture and structured lipid oils showed ME values of 8239, 8199, 8839, 8268 and 8523 kcal/kg DM respectively. In the performance trial, a total of 90 piglets with 23 days of age were distributed among 5 diets, differing in the lipid source used (soybean oil, coconut oil, fish viscera oil, physical mixture or structured lipid).

Mung bean protein enhances the expansion of corn starch during twin-screw extrusion.

This study examined the effects of the inclusion of mung bean protein (MBP) on the direct expansion characteristics of corn starch during twin-screw extrusion. Six blends of corn starch and MBP isolate (0%, 5%, 10%, 15%, 20%, and 25% w/w) were hydrated to three different moisture contents (MCs) (16%, 19%, and 21% w.b.
