Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

To derive a nomogram of fetal maxillary bone length (MAX) for a Chinese population and to study whether first-trimester maternal serum levels of pregnancy-associated plasma protein-A (PAPP-A) is an independent predictor of fetal MAX.', 'This was a prospective observational study over 10 months examining Chinese women with a singleton pregnancy who attended the first-trimester screening program for Down syndrome. The subjects had the fetal crown-rump length (CRL), nuchal translucency, MAX, maternal serum PAPP-A and free beta-human chorionic gonadotropin (fbeta-hCG) levels measured. A nomogram of MAX was derived using normal pregnancies with reliable dates. The correlations between MAX, CRL, PAPP-A and fbeta-hCG levels were studied, after correction for gestational dependency using Z-score transformation for the ultrasound markers (Z-MAX and Z-CRL), and logarithmic transformation of multiple of gestation-specific medians for the biochemical markers (log10PAPP-A multiples of the median (MoM) and log10fbeta-hCG MoM), using the Pearson test and multiple regression analysis.', 'During the study period, 607 Chinese women met the inclusion criteria. The mean gestational age at the first-trimester screening was 12 + 4 weeks (SD, 4 days). Curve estimation analysis showed that a linear relationship fit best between MAX and CRL (MAX (mm) = -0.01 + 0.101 * CRL (mm); r = 0.826; P < 0.0001), and between MAX and gestational age (MAX (mm) = -8.465 + 0.170 * gestational age (day); r = 0.754; SD = 0.71; P < 0.0001). There were significant positive correlations between Z-MAX and Z-CRL (r = 0.627; P = < 0.0001), Z-MAX and log10PAPP-A MoM (r = 0.239; P = < 0.0001). Multiple regression analysis showed that both Z-CRL (P = < 0.0001) and log10 PAPP-A MoM (P = 0.048) were independent predictors for Z-MAX.

Phagocytes, especially monocytes, macrophages, and dendritic cells, play a pivotal role in the innate and adaptive immune responses during sepsis. We have shown that inhibition of histone deacetylase 6 improves survival and increases bacterial clearance in a mouse model of cecal ligation and puncture (CLP). The aim of this study was to determine whether this effect was associated with changes in the number and composition of different blood cell types in the circulation.', 'C57BL/6J mice were subjected to CLP, and 1\xa0h later given an intraperitoneal injection of either Tubastatin A dissolved in dimethyl sulfoxide, or dimethyl sulfoxide only. Sham-operated animals were treated in an identical fashion but not subjected to CLP. Forty-eight hours later, peripheral blood was obtained via cardiac puncture and analyzed using a HemaTrue veterinary hematology analyzer.', 'Tubastatin A administration increased the number of circulating monocytes in the sham-operated and the CLP animals. In comparison with the sham, CLP animals displayed an increase in the granulocyte percentage in white blood cells and decrease in the lymphocyte number and percentage, with a resultant increase in the granulocyte-to-lymphocyte ratio. Treatment of CLP animals with Tubastatin A decreased the granulocyte percentage and restored the lymphocyte number and percentage, which decreased the granulocyte-to-lymphocyte ratio. In the sham animals, Tubastatin A increased red blood cell number, hematocrit, and hemoglobin. This effect was not seen in CLP animals.

Measurement of pulse-wave velocity (PWV) is a non-invasive technique for assessing arterial stiffness. Although insulin resistance is associated with intimal-medial thickness of the carotid artery evaluated by B-mode ultrasonography, it is not known whether it is related to PWV. The aim of this study was to determine the relationship between homeostasis model assessment insulin sensitivity index (HOMA-%S) and PWV in non-diabetic subjects. We also examined the effects of oral glucose tolerance test (OGTT) 2-h glucose and plasma high-sensitivity C-reactive protein (CRP) on PWV, as these two parameters are associated with atherosclerosis.', 'A 75-g oral glucose tolerance test was performed in 1934 Japanese subjects who were undergoing health examinations. Of these subjects, we recruited 1541 non-diabetic subjects without chronic or acute inflammation, malignant diseases, autoimmune disorders, elevated serum creatinine levels, and abnormal hepatic function tests. Subjects who had an abnormal ankle/brachial blood pressure index of less than 0.9 were also excluded. Brachial-ankle PWV and plasma high-sensitivity CRP were measured on 1541 subjects who satisfied the admission criteria.', 'PWV was 12.55+/-1.61 (mean+/-sd) m/s and plasma CRP concentration was 0.4 mg/l (median, range, 0.1-5.8 mg/l) in the study subjects. By multivariate regression analysis, HOMA-%S was found to be an independent negative risk factor for PWV, while systolic blood pressure, age and triglycerides were positively associated with PWV. OGTT 2-h glucose was weakly and independently related to PWV in male subjects. Plasma CRP was not independently associated with PWV.
