Identification and Profiling Analysis of microRNAs in Guava Fruit ( L.) and Their Role during Ripening.

The guava ( L.) is a climacteric fruit with an accelerated post-harvest overripening. miRNAs are small RNA sequences that function as gene regulators in eukaryotes and are essential for their survival and development.

Identification in silico and expression analysis of a β-1-4-endoglucanase and β-galactosidase genes related to ripening in guava fruit.

Background: Guava fruit softening is a crucial process during ripening and this process involves a number of enzymes that modifies the cell wall. Two of the enzymes that regulate this process are (a) the β-1, 4-endoglucanase 17 (BEG) which hydrolyze β-1, 4 bonds from cellulose and hemicellulose, and (b) β-galactosidase (BGA) that hydrolyzes pectin chains. Bioinformatics and expression analysis information on these genes is limited in guava fruit.

[Obstetric hysterectomy in patients with accreta, increta and percreta placentae: comparison of two surgical techniques].

Objective: To analyze the maternal-fetal surgical complications techniques utilizing two obstetric hysterectomy in patients with placenta accreta, increta or percreta, in the Hospital General de Occidente, Jalisco, Mexico during the period 2011 to 2014.

Material And Methods: observational, descriptive, cross-sectional study, analyzing maternal and fetal complications in all patients diagnosed with placenta accreta, increta or percreta, intervened with two surgical techniques obstetric hysterectomy, during the period January 2011 to December 2014, using clinical records to identify the study variables. The data were analyzed on Epi-Info 7 calculating frequencies, percentages, measures of central tendency and dispersion, also resorting to the use of a hypothesis test for mean difference bleeding.
