Given a passage with a context and an answer, 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.

Context: In the past years the interaction of GH and 11beta hydroxysteroid dehydrogenase (11betaHSD) in the pathogenesis of central obesity has been suggested.', 'We studied the effects of 9 months of GH treatment on 11betaHSD activity and its relationship with body composition and insulin sensitivity in 30 men with abdominal obesity, aged 48-66 years, in a randomised, double-blind, placebo-controlled trial.', 'Urinary steroid profile was used to estimate 11betaHSD type 1 and 2 (11betaHSD1 and 11betaHSD2) activities. Abdominal s.c. and visceral adipose tissues were measured using computed tomography. Glucose disposal rate (GDR) obtained during a euglycaemic-hyperinsulinaemic glucose clamp was used to assess insulin sensitivity.', 'In the GH-treated group the 11betaHSD1 activity decreased transiently after 6 weeks (P < 0.01) whereas 11betaHSD2 increased after 9 months of treatment (P < 0.05). Between 6 weeks and 9 months, GDR increased and visceral fat mass decreased. Changes in 11betaHSD1 correlated with changes in visceral fat mass between baseline and 6 weeks. There were no significant correlations between 11betaHSD1 and 11betaHSD 2 and changes in GDR.
Answer: The study demonstrates that short- and long-term GH treatment has different effects on 11betaHSD1 and 11betaHSD2 activity. Moreover, the data do not support that long-term metabolic effects of GH are mediated through its action on 11betaHSD.
Is gH effect on enzyme activity of 11betaHSD in abdominal obesity dependent on treatment duration?

Context: The proportion of dendritic cell subpopulations in the skin is important for the severity of atopic dermatitis because topical treatment with tacrolimus leads to rapid depletion of inflammatory dendritic epidermal cells, whereas Langerhans cells (LCs) predominate in cured sites.', 'The effects of tacrolimus and TGF-beta1 on LC differentiation and the idea of tacrolimus skewing the differentiation of epidermal precursors to LCs were evaluated.', 'The presence of LC markers, MHC, and costimulatory molecules and stimulatory capacity toward T cells of monocyte-derived LCs were analyzed. Skin samples of patients with atopic dermatitis were assessed by means of immunofluorescence microscopy before and after tacrolimus treatment. TGF-beta production of skin cells was analyzed.', 'Tacrolimus and TGF-beta1 act synergistically on the generation of LCs and the expression of CD40, CD80, CD86, CD83, and MHC II; stabilize TGF-beta receptor II expression; and decrease the stimulatory capacity of LCs toward T cells. In vivo the number of epidermal LCs in tacrolimus-treated skin increased.
Answer: The synergism between TGF-beta1 and tacrolimus leads to the generation of LCs, reduced expression of costimulatory and MHC II molecules, and reduced stimulatory activity. Shifting the balance of the dendritic cell population to LCs might be of major importance for the therapeutic effect of tacrolimus.
Do tacrolimus and TGF-beta act synergistically on the generation of Langerhans cells?

Context: It has been shown that maternal mental health is associated with poorer skills development in the offspring. However, the evidence evaluating the association between social anxiety disorder (SAD) and cognitive or language development, is scarce.', 'To evaluate the association between maternal SAD and performance in cognitive and language tests in 30-month old children.', 'This was a cohort study involving young women evaluated since pregnancy.', 'We evaluated 520 mother-child dyads who received prenatal medical assistance through the National Public Health System in a southern Brazilian city, from October 2009 to March 2011.', 'We used the Mini Neuropsychiatric Interview Plus (MINI Plus) to assess SAD among young mothers. Cognitive and language performance in their offspring was analyzed using the Bayley Scales of Infant and Toddler Development - 3rd Edition.', 'We found an association between maternal SAD and performance in cognitive and language tests. Children of mothers with SAD had in average 4.5 less points in the Bayley scale, when compared to those with mothers without SAD: in the cognitive (=-4.53 [95% CI -7.8; -1.1] p=0.008) and language subscales (=-4.54 [95% CI -9.0; -0.5] p=0.047).
Answer: Our findings suggest that children with mothers suffering from SAD have poorer cognitive abilities and language skills.
