In the Colegio de Postgraduados in Mexico, we have generated lines of maize (Zea mays L.) with the particularity that from a seed two or more stalks emerge and develop normally, calling that character “tallos gemelos.” This trait possibly modifies the proportions of the constituent tissues of the seed and could increase the nutritional and nutraceutical quality of the grain. The aim of this study was to evaluate the germination percentage and quantify and describe the types of phenotypic expression of seedling with twin stalks in the lines. 100 seeds of each of the 26 S5 lines tested were used. At 15 days after planting in a greenhouse, the seedlings were classified based on their morphology. The results showed that, on average, the lines had 81.3% of emergence and 51% of twin stalks. Eight types of phenotypic expression in seedlings were identified and described with the character “tallos gemelos”; Type II showed the highest proportion (59.5%). The phenotypical expressions identified in seedlings with the “tallos gemelos” trait are evidence of epigenetic mechanisms, since they present one of the features of epimutants, which is that they are reversible, that is; they can return to the original phenotype, in the present circumstance to normal plants (single stalk).

Abstract Objective To evaluate the safety of early oral feeding in patients with type II diabetes after radical resection of esophageal carcinoma. Methods The clinical data of 121 patients with type II diabetes who underwent radical resection of esophageal carcinoma in the department of cardiothoracic surgery of Jinling Hospital from January 2016 to December 2018 were retrospectively analyzed. According to the median time (7 days) of the first oral feeding after surgery, the patients were divided into early oral feeding group (EOF, feeding within 7 days after surgery, 67 cases) and late oral feeding group (LOF, feeding after 7 days, 54 cases). Postoperative blood glucose level, incidence of complications, nutritional and immune indexes, inflammatory indexes, normalized T12-SMA (the postoperative/preoperative ratio of vertical spinal muscle cross-sectional area at the 12th thoracic vertebra level) and QLQ-C30 (Quality Of Life Questionnaire) scores were recorded and compared in the two groups. Results There was no statistical difference in preoperative nutritional index and postoperative complication rates between the EOF and LOF group (p > 0.05). The postoperative nutritional index (ALB, PA, TRF, Hb) and immune index (IgA, IgG, IgM) of the EOF group were higher than those of the LOF group (p < 0.05), and the inflammatory indicators (CRP, IL-6) of the EOF group were significantly lower than those of the LOF group (p < 0.05). Moreover, postoperative T12-SMA variation and QLQ-C30 scores of the EOF group were higher than those in LOF group (p < 0.05). Conclusions Early oral feeding is safe and feasible for patients with type II diabetes after radical resection of esophageal cancer, and it can improve short-term nutritional status and postoperative life quality of the patients.

Abstract: Angico is a species found in several environments in Brazil, with several applications. It is used in the timber industry and mainly in folk medicine. In order to verify a variation in the biometric characteristics and the quality of seeds from different mother-plants in different harvesting years, the following variables were studied: moisture content, diameter, density, electrical conductivity, fresh and dry matter of seedlings, germination percentage and kinetics, in a completely randomized design with a 2x3 factorial arrangement (lots x size). The obtained results showed that angico seeds from different lots showed different physiological quality, possibly due to the climate variations to which mother-plants were submitted in the different years. Seed size directly interferes with seedling growth under both controlled and greenhouse conditions, and it can be used as a vigor indicator for angico seeds.
