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: To investigate the effects of interval aerobic training combined with strength-endurance exercise (IASE) and caloric restriction (CR) on body composition, glycaemic and lipid profile and inflammatory markers.', 'Thirty-two Zucker diabetic fatty rats were randomised into 4 groups (sedentary+CR; sedentary+adlibitum; IASE+CR; and IASE+adlibitum). Training groups conducted an IASE programme in the same session, 5 days/week for 2 months. Body weight, fat and muscle mass and body water were measured using a body composition analyser. Plasma total, LDL and HDL cholesterol, phospholipids, triglycerides, insulin, adiponectin, tumour necrosis factor alpha, interleukin 1 and 10 were measured. Blood fasting and postprandial glucose were assessed. Body weight was lower in the CR compared to the adlibitum groups (p<0.001). Fat mass was lower in the CR compared to the adlibitum (p<0.05) and in the IASE compared to the sedentary groups (p<0.001), but IASE increased lean mass (p<0.001). Triglycerides were lower in the CR compared to the adlibitum groups (p<0.001) whereas total and LDL-cholesterol and fasting glucose were reduced only in the IASE groups (all, p<0.001). Phospholipids decreased in the CR compared to the adlibitum (p<0.05) and the IASE compared to the sedentary groups (p<0.001). The area under the curve after oral glucose tolerance test, insulin and homoeostatic model assessment were lower in the IASE and the CR compared to the sedentary and adlibitum groups, respectively (all, p<0.001). Adiponectin was lower in the CR groups (p<0.001).\Question: Does interval aerobic training combined with strength-endurance exercise improve metabolic markers beyond caloric restriction in Zucker rats?

Answer: Overall, IASE as well as CR were both useful interventions, especially when combined. However, IASE showed greater improvements on body composition, inflammatory and glycaemic profile than CR did.

Question: Context: Ingested proteins are known to stimulate a rise in insulin and glucagon concentrations. In our effort to explain this effect, we have begun to measure the effect of individual amino acids.', 'The objectives were to determine the effect of lysine ingestion on insulin and glucagon concentrations and whether the effect is moderated by glucose ingestion.', 'Thirteen healthy subjects were studied on 4 occasions. Water, 25 g glucose, 1 mmol lysine/kg lean body mass, or lysine plus glucose was given on separate occasions at 0800 after a 12-h fast. Serum lysine, glucose, insulin, and glucagon were measured during a 2.5-h period. The amount of lysine provided was equivalent to that present in a 672-g (24-oz) steak.', 'Lysine ingestion resulted in an approximately 3-fold increase in lysine concentration and in a small decrease in glucose concentration. When lysine was ingested with glucose, the 2.5-h glucose area response decreased by 44% (P < 0.02). Lysine alone increased the insulin area response modestly; the insulin increase when lysine was ingested with glucose was similar to that when only glucose was ingested. Lysine stimulated an increase in glucagon (P < 0.02), whereas glucose decreased glucagon.\Question: Does lysine ingestion markedly attenuate the glucose response to ingested glucose without a change in insulin response?

Answer: Lysine ingestion results in a small decrease in serum glucose and an increase in glucagon and insulin concentrations. Lysine ingested with glucose dramatically attenuated the glucose-stimulated glucose response, but there was no change in insulin response. Whether similar effects will be observed with more physiologic doses of lysine remains to be determined.

Question: Context: The mental gland pheromone of male Plethodon salamanders contains two main protein components: a 22 kDa protein named Plethodon Receptivity Factor (PRF) and a 7 kDa protein named Plethodon Modulating Factor (PMF), respectively. Each protein component individually has opposing effects on female courtship behavior, with PRF shortening and PMF lengthening courtship. In this study, we test the hypothesis that PRF or PMF individually activate vomeronasal neurons. The agmatine-uptake technique was used to visualize chemosensory neurons that were activated by each protein component individually.', 'Vomeronasal neurons exposed to agmatine in saline did not demonstrate significant labeling. However, a population of vomeronasal neurons was labeled following exposure to either PRF or PMF. When expressed as a percent of control level labeled cells, PRF labeled more neurons than did PMF. These percentages for PRF and PMF, added together, parallel the percentage of labeled vomeronasal neurons when females are exposed to the whole pheromone.\Question: Do male pheromone protein components activate female vomeronasal neurons in the salamander Plethodon shermani?

Answer:
This study suggests that two specific populations of female vomeronasal neurons are responsible for responding to each of the two components of the male pheromone mixture. These two neural populations, therefore, could express different receptors which, in turn, transmit different information to the brain, thus accounting for the different female behavior elicited by each pheromone component.
