Five-Year Outcomes of Gastric Bypass in Adolescents as Compared with Adults. Reply

This protocol is for the performance of one-anastomosis gastric bypass (OAGB) on rat. The operator performs a long and tubular-stapled gastric pouch followed by hand-sewn anastomosis. For this model, the operator reproduces the same ratio between biliopancreatic and common limb in humans; therefore, the biliopancreatic limb measures 35 cm.

Roux-en-Y gastric bypass (RYGB) is performed to treat obesity and diabetes. However, the mechanisms underlying RYGB's efficacy are not fully understood, and studies are limited by technical difficulty leading to high mortality in animal models. This article provides instructions on how to perform RYGB in rats with high success...

This video describes a bariatric surgery-Roux-en-Y procedure. This involves the cutting of the jejunum- the middle portion of the intestine- to generate two intestinal limbs. The biliary limb is attached to the existing intestinal loop and the alimentary limb is attached to the stomach, creating a gastric bypass. The gastric bypass created here helps to decrease the nutrient uptake and efficiently reduces body...

Δ9-tetrahydrocannabinol (THC) is the intoxicating constituent in cannabis and a controlled substance in the United States. This article outlines standard procedures for obtaining, storing, and administering THC to mice complying with current legal regulations and briefly introduces a method to assess basic pharmacodynamic effects of THC in...

Bariatric surgery is the most efficient way to reduce body weight and the deadly metabolic complications (diabetes, obesity, and dyslipidemia) frequently associated with morbid obesity. Mouse models of bariatric surgery represent a unique asset for deciphering molecular mechanisms behind the beneficial effects of these surgeries on diabetes, hypertension, and...

A revisionist approach to Jean Piaget's theory of cognitive development has brought new insights that challenge and reinterpret his established ideas. Piaget proposed that the formal operational stage, emerging in adolescence, represents the culmination of cognitive maturity. During this stage, individuals are said to develop abstract thinking, engage in systematic problem-solving, and show a form of egocentrism, believing others are as preoccupied with their behavior as they are...
