instruction:
In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
question:
Context: Surgery has been the gold standard in the treatment of adult pyloric stenosis (APS). The introduction of proton pump inhibitors (PPIs) in 1989 revolutionised the treatment of peptic ulcer disease and its complications.', 'We carried out a prospective study to evaluate the effectiveness of PPIs as an alternative to surgery for treatment of APS. Six consecutive patients admitted with a diagnosis of adult peptic pyloric stenosis between November 1999 and August 2002 were studied. The diagnosis was confirmed with endoscopy. All patients were commenced on a twice-daily dose of intravenous PPI. This was changed to oral treatment after 2 days. Main outcome measures evaluated were resolution of symptoms on PPIs and failure of medical therapy.', 'There were five females and one male. Median age at diagnosis was 72 years (range, 30-90 years). Median duration of symptoms was 2 weeks (range, 1-5 weeks). Of the patients, five had a history of peptic ulcer disease. Complete resolution was achieved in 5 patients (83%). Median duration for resolution of symptoms was 9 days (range, 5-14 days). All patients were changed to oral PPIs after 2 days. One patient did not respond to oral therapy and required surgical intervention (pyloroplasty). Median follow-up was 26 months (range, 6-48 months). There was no recurrence of symptoms. All patients were discharged on low-dose PPI.\Question: Is proton pump inhibition a feasible primary alternative to surgery and balloon dilatation in adult peptic pyloric stenosis ( APS ) : report of six consecutive cases?
answer:
This study supports the view that proton pump inhibitors are a safe and feasible alternative to surgery in adult pyloric stenosis secondary to peptic ulcer disease.

question:
Context: The study focuses on the analysis of the possible relationship between a common NYD-SP18 (rs6971091, G>A) gene polymorphism and weight loss after lifestyle intervention (combined dietary intake and physical activity) in overweight/obese females.', 'We genotyped 139 unrelated non-diabetic Czech females (49.5 13.3 years, average BMI at baseline 32.2 4.6 kg/m. Biochemical and anthropometrical measurements were performed before and after ten weeks of lifestyle intervention.\Question: Do body Composition Changes in Adult Females after Lifestyle Intervention Are Influenced by the NYD-SP18 Variant?
answer:
Overweight/obese female carriers of the NYD-SP18 rs6971091 GG genotype exhibited a more beneficial response to the intensive lifestyle intervention than others.

question:
Context: The renin-angiotensin system (RAS) plays a critical role in blood pressure control and body fluid and electrolyte homeostasis. In the past few years, angiotensin (Ang) (1-7) has been reported to counteract the effects of Ang II and was even considered as a new therapeutical target in RAS. The present study aimed to investigate the effect of Ang (1-7) administration on a diabetic animal model and the modulation on local RAS.', 'Streptozotocin (STZ) injection-induced diabetic rats were used in the experiment. The animals were divided into 3 groups: (1) control; (2) STZ-induced diabetes; and (3) STZ-induced diabetes with chronic Ang (1-7) treatment [D+Ang(1-7)]. In the D+Ang(1-7) group, a dose of 25 microg x kg(-1) x h(-1) of Ang (1-7) was continually injected through the jugular vein by embedding miniosmotic pump for 6 weeks. Plasma glucose, ratio of kidney to body weight, and 24 h urine protein and serum creatinine were monitored by conventional measurement. Plasma and renal Ang II levels were measured by radioimmunoassay. Ang-converting enzyme (ACE), ACE2, Ang II type 1 (AT1) receptor, Ang II type 2 (AT2) receptor, Ang (1-7) Mas receptor, and TGF- beta1 mRNA levels were measured by real time PCR; ACE, ACE2, and TGF- beta1 protein levels were analyzed by Western blotting.', 'The renal function of diabetic rats was significantly retrogressed when compared with that of control rats. After the treatment by constant Ang (1-7) vein injection for 6 weeks, renal function was found to be even worse than diabetic rats, and both TGF-beta1 mRNA and protein levels were elevated in the D+Ang(1-7) group compared with the diabetic rats. The real-time PCR result also showed an increase in ACE mRNA expression and decrease in ACE2 mRNA level in the D+Ang(1-7) group when compared with diabetic rats. The number of AT1 receptors increased in the Ang (1-7)-injected group, while the number of AT2 and Mas receptors decreased.\Question: Does chronic angiotensin ( 1-7 ) injection accelerate STZ-induced diabetic renal injury?
answer:
Exogenous Ang (1-7) injection did not ameliorate STZinduced diabetic rat renal injury; on the contrary, it accelerated the progressive diabetic nephropathies.
