The industrial obtainment and manufacturing of food cause high levels of pollution because of the generation of waste byproducts. Over the past few years, there has been a significantly increased interest in preserving, restoring and establishing an ecological balance during food production. Many investigators propose biotechnological solutions to the treatment of industrial wastes, especially waste from the dairy industry. The aim of this review is to present biotechnological approaches to the treatment and utilization of wastes from the dairy industry, specifically for milk whey and also discussed biotechnological methods to reduce environmental pollution and obtain chemical compounds with potential applications in the industry.

Journal of Chemistry and Chemical Engineering 2013年第2期7卷 145-153页

The habanero chili （Capsicum chinense Jacq.） is a species of great demand in the domestic and international markets. One problem in the cultivation is low percentage of seed germination. There is little information on the use of promoters and imbibition time to increase this parameter, without compromising the quality of seedlings. In this context, authors assessed the independent effect of GAs （gibberellic acid） and KnOs at concentrations of 0, 100, 200, 300, 400 and 500 mg·L1. Seeds without preconditioning were the witness. The experimental unit was a Petri dish with 50 seeds on filter paper placed equidistant. There were three replicates per treatment and the experimental design was randomized complete block. Imbibition time was 24 h. The experimental units were kept in an incubator at 22 ± 2 ℃. From the time of planting and for periods of 24 h for 14 d, experimental units were reviewed to determine the time at the beginning of germination and the total cumulative percentage. The authors also determined the number of normal and abnormal seedlings, the length of hypocotyl and radicle, weight of fresh and dry matter of seedlings. On the fifth day after sowing in vitro, concentrations of 500 mg·L^-1 of GAs, 300 and 400 mg·L^-1 KnO3, increased 208% the percentage of seed germination of habanero chile. On day 14 after sowing in vitro concentrations of 500 mg·L^-1 GA3, 300 and 400 mg·L^-1 KnO3, increased 23% normal seedlings and 40% dry matter thereof, with respect to seeds obtained without preconditioning. Unconditioned seeds before sowing produced 125% more seedlings.

Anthropometric Analysis of the Upper Eyelid and Eyebrow in Patients Attended by the Plastic and Reconstructive Surgery Service of the Hospital Central Sur De Petróleos Mexicanos

Journal of Biosciences and Medicines 2022年第8期10卷 47-56页

作者： Alejandro Costa-Dulché Jaime García-Espinoza daniel De-Luna-Gallardo Cuahutemoc Márquez-Espriella Rodrigo Dávila-Díaz Blanca Arámbula-Sánchez Marco Cuervo-Vergara David flores-Soto Hospital Central Sur de Alta Especialidad de Petróleos Mexicanos Mexico City Mexico

Upper eyelid blepharoplasty is one of the most frequently performed surgeries by plastic surgeons worldwide. A prospective observational study was conducted to describe the anthropometric measurements of the upper eyelid and eyebrow in a Mexican population. The researcher measured the anthropometry of the eyelids and eyebrows to establish the diagnosis and surgical plan according to the checklist created and applied by the plastic and reconstructive surgery service. In anatomical position with a caliper instrument, the marginal reflex distance (MRD1), the tarsal thickness, the length of the vertical and horizontal slit, and finally the distance at which the external canthus is located with respect to the internal canthus were measured in millimeters. For the anthropometry of the eyebrows, the distance from the eyebrows to the hairline, the position in millimeters of the orbital rim with respect to the eyebrow, and the angle of its apex were measured. A sample of 210 patients was obtained, of which 65 were male and 145 females, divided by age groups. It was observed that in the three age groups, females presented a vertical palpebral fissure with a higher mean than males. Similar is the case of tarsal thickness, in which the difference was significantly greater in the female of the three age groups. On the other hand, it was observed that the horizontal slit in males was higher than that of females, while the MDR1 was similar in both sexes. Finally, it was identified that in the group of 41 to 50 years old significant decreases are observed both in the vertical cleft, tarsal thickness and the position of the external canthus compared to the group of 20 to 30 years old, this is due to the aging process. When evaluating the anthropometrics of the eyebrows, a greater distance from the trichion to the eyebrow was observed in males than in females, in contrast to the position of the eyebrow with respect to the supraorbital rim and its apex, in which it was shown that in f
