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.

Q: Context: Side effects of mitotane (o,p'-DDD) have suggested estrogenic effects.", "The objective of the study was to explore o,p'-DDD potential estrogenic effect on SHBG and corticosteroid-binding globulin (CBG).", 'Human hepatoma cell lines (HepG2), lacking estrogen receptor (ER)-alpha, and Hep89, stably transfected by ERalpha, were used.', 'The study was conducted at an academic research laboratory and medical center.', 'The study included 10 male patients with recurrent adrenal carcinoma, receiving mitotane (4-6.5 g daily) for more than 6 months.', 'The main outcome measures were SHBG/CBG mRNA levels measured by real-time PCR, culture medium SHBG/CBG concentrations measured by specific immunoassays, and transient transfection experiments with human SHBG proximal promoter reporter constructs.', "Increased serum SHBG and CBG concentrations, which exceeded normal male limits, were observed in most mitotane-treated patients. In the HepG2 cell line, 17beta-estradiol (E2) or o,p'-DDD treatment had no effect on mRNA or SHBG/CBG concentrations. In contrast, in the Hep89 cell line, E2 increased concentrations of SHBG (r = 0.44, P < 0.0001) and CBG (r = 0.585, P < 0.0001) secreted into culture media in a dose-dependent manner. o,p'-DDD significantly increased SHBG (150% vs. control, P < 0.05) and CBG (184% vs. control, P < 0.05) production by Hep89 cells, at a concentration of 2 x 10(-5) m. Transient transfection experiments in Hep89 cells showed that E2 or o,p'-DDD treatment did not increase the transcriptional activity of the minimal proximal promoter of human SHBG gene.
Answer: Mitotane increased SHBG/CBG gene expression and liver production by mechanisms requiring the presence of ERalpha.

Q: 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.

Q: Context: The issue of platelet function in infants and neonates is of interest, and current data are debatable. A new method for assessing platelet function involves using the cone and plate(let) analyzer (CPA), applicable for small (0.2 ml) whole blood volumes. We used polystyrene surface-coated plates to evaluate cord blood neonatal platelet function under flow. One hundred and sixty full-term and 29 preterm infants born at the Sheba Medical Center between March 2003 and January 2004 were evaluated for platelet adhesion measured as surface coverage (SC; the percentage of total area covered by platelets) and platelet aggregation, defined as the average size (AS) of the aggregates. Platelets from preterm infants displayed less platelet adhesion than did those from full-term infants. Platelet SC correlated with gestational age in all infants (p < 0.05), and both groups exhibited similar aggregation (AS). AS values, however, were significantly lower than the normal adult range in our laboratory. Infants born to mothers with pregnancy-induced hypertension displayed significantly lower SC. No association was found between CPA and postnatal complications.
Answer: CPA provides a rapid, feasible option for testing platelet function in neonates. Its potential predictive value deserves further attention, and more extensive studies are warranted.

A:
Does platelet function of newborns as tested by cone and plate ( let ) analyzer correlate with gestational Age?
