Large glenoid bone loss defects are associated with higher failure rates after arthroscopic Bankart repair in cases of glenohumeral anterior instability, further necessitating bone graft reconstruction. Because most techniques use strong initial fixation using metal devices, bone graft resorption considered to be closely related to the presence of metal components is a potential shortcoming of these techniques. We describe an arthroscopic technique for anatomical reconstruction of the glenoid that uses a tricortical iliac crest with a metal-free fixation method using 2 ultra-high-strength sutures (FiberTape Cerclage System; Arthrex, Naples, FL), which provide substantial stability to the graft, and finishing with a capsulolabral reconstruction.

Acromioclavicular dislocations are some of the most frequently recorded and controversial injuries in the athletic population. These injuries have historically been a matter of disagreement between surgeons, particularly when it comes to the surgical technique used to treat them, its approach, or its timing. Consensus over the "gold standard" procedure to treat them is yet to be established. Even though numerous surgical techniques have already been described, the number of complications and loss of reduction remains a matter of concern for treating physicians. Here, we present an arthroscopically assisted coracoclavicular and horizontal acromioclavicular fixation technique in a modified figure-of-eight configuration using 2 strong FiberTape Cerclage sutures, with measurable tension, for the comprehensive treatment of acromioclavicular joint dislocations.

The fatty acids profile and lipids content of the Macadamia integrifolia and Macadamia tetraphylla varieties and interspecies hybrids, M. integrifolia and M. tetraphylla were analyzed. Total lipids content ranged from 70.9 to 79.7 g of oil per 100 g−1 dry-solids. Gas chromatography/mass spectrophotometry identified 20 fatty acids, the most abundant of which were oleic acid (40 to 51%), palmitoleic acid (24 to 36%), and palmitic acid (8.4 to 13.1%). Fatty acids concentration differed between varieties and hybrids (Multivariate analysis of variance, F = 13.89, p < 0.0001). A ratio of monounsaturated fatty acids:saturated fatty acid values ranged from 2.8 to 4.6. The Huatusco variety (M. integrifolia and M. tetraphylla) exhibited the highest percentage of lipids (79.7 g of oil per 100 g−1 DS) and the highest monounsaturated fatty acids:saturated fatty acid (4.6), thus highlighted its potential applications within the food industry. The Cate variety (M. integrifolia and M. tetraphylla) had the lowest ...

The aim of this work was to study the effect of the addition of passion fruit pulp (PFP: 0–7 %), the variation of barrel temperature in the third zone extruder (BT: 80–140 °C) and feed moisture (FM:16–30 %) in a blend of corn starch and passion fruit pulp on different physicochemical characteristics of directly expanded snacks by extrusion technology. Single-screw laboratory extruder and a central, composite, rotatable experimental design were used. Expansion index of extrudates ranged between 1.0 and 1.8. Decreasing of feed moisture (18 %), passion fruit pulp concentration (1.42 %) and the increasing of barrel temperature (127 °C) resulted in higher expansion index. The increasing of feed moisture and passion fruit pulp concentration resulted in higher penetration force values of extrudates. The passion fruit pulp concentration showed a highly significant effect (p ≤ 0.01) on the L *, a * and b * parameters. Passion fruit pulp has a reasonable source of β-carotene, proteins and dietary fibers that can be added to expanded snacks.

The objective of this study was to develop with thermoplastic extrusion amaranth starch derivatives and to characterize and evaluate their functionality as encapsulating agents of Bifidobacterium breve ATCC 15700 and Lactobacillus casei ATCC 334 during spray drying. The survival of both probiotics during storage at different water activities and at two storage temperatures, their viability in a food model system, and their tolerance to a simulated gastrointestinal tract were determined. Native amaranth starch was chemically modified to obtain phosphorylated, acetylated, and succinylated starch. Starch derivatives were reduced in viscosity, and the solubility in water was increased. In general, the modified amaranth starches and control corn starch did not provide good protection to both probiotics during storage at 25°C. However, there was excellent viability during storage at 4°C for both probiotics. Microcapsules showed a uniform coverage of the cells. Storage for 35 days at 25°C of blends of o...

Extruded blends (EB) of whey protein concentrate 35 (WPC 35)–corn starch–sugarcane bagasse with 0%, 25%, and 50% substituted yogurt formulations were evaluated for some functional characteristics. Yogurts substituted with EB showed higher viscosity and lower syneresis index than that without EB. During storage for 48 h, the syneresis values of yogurt with and without EB decreased. The pH values and color differences (ΔE) decreased slightly in the yogurts formulated with EB. However, the color differences were not statistically significant (p > 0.05) and were also acceptable to the judges. In general, yogurts substituted with EB at different levels had sensory attributes of taste, acidity, texture, and viscosity scores similar to those observed for yogurt with no EB. Scores of yogurts were not affected significantly with substitution of EB at all the levels.

The determination of the number of fungiform papillae (FP) on the human tongue is important for taste sensitivity studies. Most of the time, the counting of the FP is done manually. In this paper we propose a novel algorithm to count the FP using shape characteristics measured by cross-correlation. The accuracy of the algorithm is evaluated by counting the FP manually on the same images and then doing a statistical analysis. A Poisson regression model is fitted using maximum likelihood. The result is that the algorithm counts are very similar to the human experts. Another advantage of the algorithm is its facility of use, velocity and that it can work on a plain tongue image, without the need to stain the tongue as is usual in manual counting. An algorithm for the automatic detection and counting of fungiform papillae was proposed.The algorithm is based on shape of the fungiform papillae as measured by cross-correlation.The algorithm counts the fungiform papillae very similar to the manual procedure.This algorithm is valuable to the sensory evaluation and medical community.

La tuna roja de Opuntia ficus-indica (L.) Mill. (Cactaceae) es una fuente importante de compuestos biactivos y funcionales, pero tiene dificultades para su almacenamiento y comercialización. Por lo tanto se realizó un estudio del efecto de las atmósferas controladas sobre los frutos mínimamente procesados para conservar los compuestos antioxidantes a temperatura de 5 °C y durante 16 días de almacenamiento en atmósferas controladas. Al final del mismo se registró que los tratamientos con 5% O2 + 95% N2 y 10% CO2 + 5% O2 + 85% N2 mantuvieron el nivel de betalaínas (125,6 mg l-1, 126,16 mg l-1) y actividad antioxidante (263,7 μmol Eq Trolox 100 ml-1, 267,6 μmol Eq Trolox 100 ml-1), respecto al contenido inicial evaluado (116,1 mg l-1, 270,4 μmol Eq Trolox 100 ml-1). Mientras que el contenido de polifenoles no varió en el tratamiento con 5% O2 + 95% N2 (d0-16 ≈ 65,6 - 57,7 mg EAG 100 ml-1). Los resultados indican que aún después de 16 días de almacenamiento con el uso de atmósferas controladas, la tuna roja mínimamente procesada tiene alta actividad antioxidante puesto que conserva el contenido de betalaínas y polifenoles.

Starch derivatives of taro (Colocasia esculenta L. Schott) and rice were characterized as wall materials of orange oil (d-limonene) by spray drying. Native starches were initially hydrolyzed with HCl and then esterified. Succinylated starches were modified using a conventional method in a slurry and were extruded; whereas, the phosphorylated starches were modified using the extrusion process. Viscosity and solubility of starches reduced after acid hydrolysis, derivatization, and extrusion. The particle size of the wall materials ranged between 20.05 and 31.81 μm. The encapsulation efficiency of the phosphorylated taro, rice, and waxy corn starches was 96.9, 96.8 and 97.1% respectively, and 98.6, 98.1, and 98.8% for succynilated taro, rice, and waxy corn starches, respectively. Starch derivatives of taro and rice could potentially be used as wall materials of orange oil d-limonene.

In the present work, we studied the effect of calcium addition, pH adjustment, and ultrafiltration on the physico-chemical characteristics and cheesemaking properties of goat milk that contained low synthesis-rate α s1 -casein variants. Calcium addition resulted in an increase in the colloidal calcium content of milk but had no major effect on its renneting properties. Milk acidification caused a major modification of calcium equilibria, a decrease of rennet clotting time and an increase of gel firmness. Milk protein enrichment by ultrafiltration led to an increase in the curd firming rate and its maximum strength. This treatment also improved the dry matter recovery during cheese manufacture, proportionally to milk solids enrichment. The three treatments had cumulative effects (no interaction) and it is concluded that an adequate combination of acidification and protein concentration can improve the cheesemaking properties of deficient milk to make them equivalent to those of milk that contain favourable variants.

"Se evaluaron las características físico-químicas de frutos de siete variedades de tuna (Opuntia spp.) que se producen en México, y la estabilidad del pigmento (betalaínas) de dos de ellas fue monitoreado durante 91 días bajo almacenamiento en tres niveles de pH y dos temperaturas. El intervalo de los valores fue registrado para las variables: contenido de agua (81.34-85.29 g 100 g-1 de peso fresco (PF)), cenizas (0.48-0.57 g 100 g-1 PF), proteína (0.20-0.39 g 100 g-1 PF), grasa (0.13-0.83 g 100 g-1 PF), fibra cruda (0.33-0.72 g 100 g-1 PF), sólidos solubles totales (9.67-14.12 ºBrix), acidez titulable (0.020-0.074 g 100 g-1 PF) y pH (3.32-5.81). La concentración del pigmento tuvo una amplia variación entre las variedades: Pintadera tuvo la mayor concentración (86.69 mg betanina 100 g-1 PF), seguida de Tapón Aguanoso (58.12 mg betanina 100 g-1 PF). Bajo todas las condiciones de almacenamiento, el extracto de Tapón Aguanoso (tiempo de vida media = 321 a 533 días) tuvo mayor estabilidad que el extracto de Pintadera."

This study was undertaken to determine the effect of dietary supplementation of sunflower seed in cows on the chemical composition of milk and dairy products. Cream, butter and butter oil were prepared from milk produced by cows fed a control diet (control products) or diet supplemented with 11.2% sunflour seed (CLA-rich products). Milk samples collected were determined for lactose. A sample of CLA-rich or control product was determined for fatty acid profile as well as fat, protein and ash contents. The index of atherogenicity (IA) and the index of thrombogenicity (IT) were also calculated. Results revealed that there was no effect of the inclusion of sunflower seed in the diet on the lactose content in milk and total fat, protein and ash contents in the dairy products. Average contents of conjugated linoleic acid (CLA) and transvaccenic acid (TVA), expressed as g/100g total fatty acid were 0.54 and 1.6, respectively in the control products, and 2 and 6.4, respectively in the CLA-rich products. The content of either CLA or TVA was approximately four fold higher in the latter products. Moreover, CLA-rich products showed considerably low IA and IT, which were, respectively, 38.4 and 25.0% less than those from control products. Fatty acid profiles were unaffected during processing, which demonstrates that CLA is a stable component in the dairy products analyzed. It was concluded that dietary supplementation of sunflower seed in cows increases the CLA and TVA contents in milk, which may contribute to the reduction of the risk of cardiovascular diseases in humans.

The objective of this paper is to review the main research works related to functional foods and ingredients derived from milk. Research in functional foods has increased during last twelve years with the intention of increasing life expectancy and improving human health conditions. Probiotics, prebiotics, bioactive peptides or proteins, dietetic fibers and fatty acids, as well as the addition of fitochemical compounds in dairy products and a record of some allergic compounds are also discussed. The demand of this kind of products is increasing due to intense advertising campaigns posted in many countries. Basically, these campaigns promise better health and/or the prevention of certain illnesses. Milk contains diverse constituents with physiological functionality, which might change the traditional view point that we have about drugs. The topic of functional foods in general, and specifically that from milk and dairy products, has still not been completely exploited, and in the future it will be found that the best work has not been carried out in this area.

Se presenta el análisis de una encuesta repetida para evaluar el impacto de una campaña publicitaria diseñada para motivar el incremento del consumo de frutas y verduras, en el Estado de Veracruz, México. Se usaron los datos agregados a nivel municipal y con ellos se construyeron indicadores socioeconómicos y de perfiles de consumo de alimentos; se realizaron comparaciones por zonas geográficas. Con el propósito de explicar el impacto de la campaña y su efecto en el cambio de dieta en las familias, se ajustó un modelo de regresión bivariada, encontrándose que el conocimiento de la campaña está asociado al nivel socioeconómico, y que la campaña influyó más en municipios con alto índice de consumo de frutas y verduras. El menor impacto de la campaña en el cambio de dieta de la familia se dio en municipios con alto consumo de verduras, pero bajo consumo de frutas.
