Las fracturas de la raíz también llamadas intra alveolares radiculares, son aquellas que afectan a la dentina, al cemento y lapulpa, se caracterizan por presentar patrones complejos de curación, debido al deterioro de la pulpa, el ligamento periodontal,la dentina y el cemento. La mayoría de estas fracturas se producen por un golpe directo contra el suelo, un cuerpo extrañoque incida sobre el diente o accidentes automovilísticos y deportivos. En el presente artículo se describe el tratamiento yseguimiento a 2 años 4 meses del caso de una niña de 10 años de edad que después de un traumatismo fue sometida a untratamiento no adecuado, que le causaba mucho dolor, radiográficamente se observó la ausencia del tercio apical en el diente21 y una movilidad grado III del mismo. Se modificó el tratamiento prolongando la vida del diente en boca.

Se presenta un caso de paciente con dolor abdominal asociado a ictericia y hemorragia digestiva alta (hematoquezia, melena) causado por hemobilia secundaria a ruptura de pseudoaneurisma de una rama de la arteria hepática derecha. El diagnóstico se realizó por medio de endoscopía digestiva alta, realizando arteriografía con embolización selectiva cesando el sangrado.

Background and objective: Andean lupin (Lupinus mutabilis Sweet) has health benefits with promising possibilities for food industry. The aim of this research was to determine the effect of processing (water debittering, extrusion, and spray-drying) on chemical composition, heat damage and in vitro protein digestibility in Andean lupin. Findings: The processing treatment modified all the parameters while the genotype showed limited effect. The untreated lupins had high protein and lipid content (47.4 and 16.2 g/100 g dry matter). The extruded products showed higher protein content (55.7 g/100 g) and digestibility (68.1%) than the untreated lupins, along with limited heat damage (8.7 mg furosine/100 g protein). Spray-drying led to the lowest protein content (31.8 g/100 g) and, when maltodextrin was used, the highest heat damage (54.1 ± 20.7 mg furosine/100 g protein; 0.60 mg hydroxymethyl...

The effect of tomato lycopene-rich extract (TLE) addition on shelf-life of linseed oil was evaluated. Linseed oil was extracted by cold pressing and TLE by supercritical CO2. Linseed oils with and without TLE addition were characterized for moisture, color, refractive index, fatty acid composition and antioxidants. Adding TLE to 80 mg lycopene/kg oil improved linseed oil stability, showing the same induction time at 110 °C (by Rancimat) of control linseed oil with 200 mg/kg butylhydroxytoluene. The increase of free fatty acid, peroxide value, p-anisidine value, K232 and K268 at 40, 50, and 60 °C until 90 days followed first-order kinetics. Rancidity rate augmented with temperature. TLE addition slowed oil degradation without changing the mechanism since the Arrhenius lines were parallel. Mean Ea were respectively 38.2, 24.7, 38.0, 38.2, 41.5 kJ/mol. TLE addition increased linseed oil s...

Andean lupin (Lupinus mutabilis) seeds are appreciated for their high protein and lipid contents and have potential applications as ingredients in food, cosmetic, and pharmaceutical industries. Nevertheless, the information about the seed composition (especially in lipophilic antioxidants) of ecotypes from distinct cropping areas is currently limited. Thus, the aim of the present research was to assess the morphological characteristics, chemical composition, tocopherol and carotenoid contents of the seeds of 33 Andean lupin ecotypes from different Peruvian regions, along with three L. albus, one L. angustifolius and one L. luteus controls. Significant differences were noted among the Andean ecotypes for all analyzed features. The protein, lipid and ash contents were 32.0–46.9, 13.6–18.6 and 2.7–4.4 g/100 g dry matter (DM), respectively. The seeds were rich in tocopherols (172.1–2...
