Effect of Chewing Gum on Duration of Postoperative Ileus Following Laparotomy for Gastroduodenal Perforations: Protocol for a Randomized Controlled Trial.

Background: Prolonged post-operative ileus is associated with increased risk of other complications, length of hospital stays and health care related costs. Chewing gum has been shown to reduce duration of ileus in many elective surgeries, but there is a paucity of randomised controlled trials (RCTs) on its effect on duration of ileus among patients undergoing emergency surgery, specifically patients with peritonitis. The aim of this study is to determine the effect of chewing gum on duration of postoperative ileus following laparotomy for gastroduodenal perforations.

The Effect of Different Bleaching Treatments and Thermal-Mechanical Cycling on the Shear Bond Strength of Orthodontic Brackets.

Objective: The aim of the present study was to compare the shear bond strength (SBS) of orthodontic brackets bonded to the enamel after at-home and in-office bleaching treatments.

Methods: Sixty bovine incisors were subjected to initial color readings and then classified into three groups: CP (16% carbamide peroxide), HP (35% hydrogen peroxide), and C (control). After treatments, new color readout was obtained, and orthodontic brackets were bonded to the bleached area.

Age variation in the body coloration of the orb-weaver spider Alpaida tuonabo and its implications on foraging.

Spiders show a repertoire of strategies to increase their foraging success. In particular, some orb-weaver spiders use attractive body colorations to lure prey. Interestingly, coloration varies with age in many species, which may result in ontogenetic variation of foraging success.

Dysregulation of the long non-coding RNA transcriptome in a Rett syndrome mouse model.

Mecp2 is a transcriptional repressor protein that is mutated in Rett syndrome, a neurodevelopmental disorder that is the second most common cause of mental retardation in women. It has been shown that the loss of the Mecp2 protein in Rett syndrome cells alters the transcriptional silencing of coding genes and microRNAs. Herein, we have studied the impact of Mecp2 impairment in a Rett syndrome mouse model on the global transcriptional patterns of long non-coding RNAs (lncRNAs).

Tumor necrosis factor alpha promoter-308G/A polymorphism in Mexican patients with patchy alopecia areata.

Background: Alopecia areata (AA) is a chronic inflammatory condition characterized by hair loss, most frequently from the scalp. Its etiopathogenesis is currently unknown, but inflammatory traits and associations with autoimmune diseases suggest that AA shares a similar origin. The tumor necrosis factor alpha (TNFα) gene, located on chromosome 6 within the major histocompatibility complex class III gene, may carry previously described polymorphisms--particularly in the promoter region, such as TNFα-308G/A--known to be risk factors in a wide variety of inflammatory pathologies.
