Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Question: We examined the effect of prior heating, by exercise and warm-water immersion, on core cooling rates in individuals rendered mildly hypothermic by immersion in cold water.', 'There were seven male subjects who were randomly assigned to one of three groups: 1) seated rest for 15 min (control); 2) cycling ergometry for 15 min at 70% Vo2 peak (active warming); or 3) immersion in a circulated bath at 40 degrees C to an esophageal temperature (Tes) similar to that at the end of exercise (passive warming). Subjects were then immersed in 7 degrees C water to a Tes of 34.5 degrees C.', 'Initial Tes cooling rates (initial approximately 6 min cooling) differed significantly among the treatment conditions (0.074 +/- 0.045, 0.129 +/- 0.076, and 0.348 +/- 0.117 degrees C x min(-1) for control, active, and passive warming conditions, respectively); however, secondary cooling rates (rates following initial approximately 6 min cooling to the end of immersion) were not different between treatments (average of 0.102 +/- 0.085 degrees C x min(-1)). Overall Tes cooling rates during the full immersion period differed significantly and were 0.067 +/- 0.047, 0.085 +/- 0.045, and 0.209 +/- 0.131 degrees C x min(-1) for control, active, and passive warming, respectively.

Answer: Does warming by immersion or exercise affect initial cooling rate during subsequent cold water immersion?

Question: Environmental conditions (eg, latitude) play a critical role in the susceptibility and severity of many autoimmune disorders, including multiple sclerosis (MS). Here, we investigated the mechanisms underlying the beneficial effects of immune regulatory processes induced in the skin by moderate ultraviolet B (UVB) radiation on central nervous system (CNS) autoimmunity.', 'Effects of UVB light were analyzed in a murine model of CNS autoimmunity (experimental autoimmune encephalomyelitis). Additionally, patients with relapsing-remitting MS were treated with narrowband UVB phototherapy. Immunomodulatory effects were examined in skin biopsies, serum samples, and immune cells of the peripheral blood.', 'Regulatory T cells (Tregs), which are induced locally in the skin-draining lymph nodes in response to UVB exposure, connect the cutaneous immune response to CNS immunity by migration to the sites of inflammation (blood, spleen, CNS). Here, they attenuate the inflammatory response and ameliorate disease symptoms. Treg-inducing tolerogenic dendritic cells (DCs) were further necessary for induction of this systemic immune regulation by UVB radiation, because ablation of Langerhans cells abolished the UVB-induced phenotype. MS patients treated with UVB phototherapy showed an increase in induced Tregs and tolerogenic DCs accompanied by the downregulation of the T-cell effector cytokine interleukin 21. The treatment further induced elevated serum levels of vitamin D.

Answer: Does ultraviolet B light attenuate the systemic immune response in central nervous system autoimmunity?

Question: It has been argued that tasks that necessitate the use of context in the service of goal-directed behaviour are disrupted in both schizophrenic patients and in animal analogues by dopamine (DA) manipulation with the prefrontal cortex being implicated.', 'To determine the effects on conditional discrimination performance of direct infusion of the DA D(1)/D(2) receptor antagonist alpha-flupenthixol into the medial prefrontal cortex (mPFC) and of its reversal potential on d-amphetamine-induced task disruption.', 'Conditional discrimination performance in which rats learn to respond on an appropriate lever, conditional upon specific auditory stimuli, was acquired and later tested under the above drug treatment protocol in extinction.', 'Conditional discrimination performance was unaffected by bilateral intra-mPFC alpha-flupenthixol at doses of 12, 24 or 36 microg/microl. A dose of D-amphetamine (1.5 mg/kg) shown previously to disrupt conditional discrimination performance was attenuated by direct PFC infusion of alpha-flupenthixol at doses of 24 and 36 but not 12 microg/microl per site.

Answer:
Does medial prefrontal cortex infusion of alpha-flupenthixol attenuate systemic d-amphetamine-induced disruption of conditional discrimination performance in rats?
