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.

[EX Q]: Context: The objective of this study was to evaluate the effects of lipopolysaccharide (LPS) endotoxemia and enteral arginine (ARG) supplementation on intestinal structural changes, enterocyte proliferation, and apoptosis in rat.', 'Male Sprague-Dawley rats, weighing 250-280 g, were divided into three experimental groups: control rats, LPS rats treated with lipopolysaccharide given ip at a dose of 10 mg/kg every 24 h (two injections), and LPS-ARG rats treated with enteral arginine given in drinking water (2%) 72 h before and following injection of LPS. Intestinal structural changes, enterocyte proliferation, and enterocyte apoptosis were determined on day 3 following the first LPS injection.', 'LPS rats demonstrated a significant decrease in bowel weight in duodenum, mucosal weight in duodenum, jejunum, and ileum, mucosal DNA and protein in jejunum and ileum, and villus height in jejunum and ileum compared to control animals. LPS rats also had a significantly lower cell proliferation index in jejunum and ileum and a higher apoptotic index in jejunum and ileum compared to control rats. LPS-ARG animals demonstrated greater duodenal bowel weight, duodenal and ileal mucosal weight, ileal mucosal DNA and protein, ileal villus height, and jejunal and ileal cell proliferation index compared to LPS animals.\Question: Does oral arginine reduce gut mucosal injury caused by lipopolysaccharide endotoxemia in rat?
[EX A]: LPS endotoxemia impairs the integrity of the gastrointestinal mucosa in rat. Decreased cell proliferation and increased apoptosis may be considered the main mechanisms responsible for the decreased cell mass. Enteral arginine administration decreases the mucosal injury caused by lipopolysaccharide.

[EX Q]: Context: To describe the findings of enhanced depth imaging (EDI) optical coherence tomography (OCT) of the lamina cribrosa (LC) in glaucoma and pachychoroid spectrum diseases associated with peripapillary retinoschisis.', 'Retrospective, observational case series.', 'A total of 16 patients from 1 institution.', 'Detailed medical case histories, optic disc and retinal imaging with EDI using the Spectralis OCT (Heidelberg Engineering, Heidelberg, Germany), and clinical course were reviewed for patients with peripapillary retinoschisis without a known predisposing condition.', 'Clinical features and findings of the EDI OCT.', 'Among the 16 eyes with peripapillary retinoschisis that had abnormal findings on EDI of the LC, 8 had glaucoma and 8 had pachychoroid spectrum diseases, including chronic central serous chorioretinopathy (CSC) (6 eyes), small pigment epithelium detachment (1 eye), and polypoidal choroidal vasculopathy (PCV) (1 eye). The abnormal LC findings were central or peripheral focal LC defects in eyes with glaucoma and LC disinsertions or peripheral focal LC defects in eyes with pachychoroid spectrum diseases. Central LC defects were related to inner layer retinoschisis, whereas LC disinsertions and peripheral LC defects were related to outer layer retinoschisis. The peripapillary retinoschisis did not show a topographic association with the underlying chronic CSC- or PCV-associated lesions. In 6 treated eyes with pachychoroid, peripapillary retinoschisis resolved along with subretinal fluid after anti-vascular endothelial growth factor injection in 4 eyes, whereas retinoschisis persisted after the resolution of subretinal fluid in 2 eyes.\Question: Do alterations of the Lamina Cribrosa Are Associated with Peripapillary Retinoschisis in Glaucoma and Pachychoroid Spectrum Disease?
[EX A]: Enhanced depth imaging OCT of the LC demonstrated alterations associated with peripapillary retinoschisis, pachychoroid spectrum diseases, and glaucoma.

[EX Q]: Context: Centrifuge training, while an integral component in pilot training, is not without risks. To date there has never been a reported case of isolated transverse process fractures associated with centrifuge training.', 'A 32-yr-old Flight Surgeon underwent centrifuge training as part of an educational course. She had increasing back pain after exposure to the centrifuge. Follow-up studies showed left L2 and bilateral L3 transverse process fractures. No other contributory causes could be identified except for mild vitamin D deficiency.\Question: Do a Report of Transverse Process Fractures Secondary to the Centrifuge in a Healthy Aviator?
[EX A]:
The etiology, incidence, and treatment of transverse process fractures are examined to better prepare the clinician for the management of these cases. Puderbaugh MA. A report of transverse process fractures secondary to the centrifuge in a healthy aviator. Aerosp Med Hum Perform. 2016; 87(7):655-658.
