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.

We conducted this study to analyze the values of the key cephalometric angular measurements of the mandible using 3-dimensional (3D) computed tomography scans.', 'In the 106 enrolled patients, a 3D cephalometric analysis was performed to measure the angular variables of the mandible. These values were compared between the two sides and between the two sexes.', 'The frontal measurements revealed that the mandibular body curve angle was larger on the left (Lt) side (right [Rt], 141.24±7.54; Lt, 142.68±6.94; P=0.002) and the gonial angle was larger on the right side (Rt, 134.37±8.44; Lt, 131.54±7.14; P<0.001). The sagittal measurements showed that the gonial angle was larger on the right side (Rt, 134.37±8.44; Lt, 131.54±7.14; P>0.05). Further, the transverse measurements revealed that the mandibular body curve angle was larger on the right side (Rt, 140.28±7.05; Lt, 137.56±6.23; P<0.001).

A colorectal tumor is not an isolated entity growing in a restricted location of the body. The patient's gut environment constitutes the framework where the tumor evolves and this relationship promotes and includes a complex and tight correlation of the tumor with inflammation, blood vessels formation, nutrition, and gut microbiome composition. The tumor influence in the environment could both promote an anti-tumor or a pro-tumor response.", 'A set of 98 paired adjacent mucosa and tumor tissues from colorectal cancer (CRC) patients and 50 colon mucosa from healthy donors (246 samples in total) were included in this work. RNA extracted from each sample was hybridized in Affymetrix chips Human Genome U219. Functional relationships between genes were inferred by means of systems biology using both transcriptional regulation networks (ARACNe algorithm) and protein-protein interaction networks (BIANA software).', 'Here we report a transcriptomic analysis revealing a number of genes activated in adjacent mucosa from CRC patients, not activated in mucosa from healthy donors. A functional analysis of these genes suggested that this active reaction of the adjacent mucosa was related to the presence of the tumor. Transcriptional and protein-interaction networks were used to further elucidate this response of normal gut in front of the tumor, revealing a crosstalk between proteins secreted by the tumor and receptors activated in the adjacent colon tissue; and vice versa. Remarkably, Slit family of proteins activated ROBO receptors in tumor whereas tumor-secreted proteins transduced a cellular signal finally activating AP-1 in adjacent tissue.

Endothelial progenitor cells (EPCs) are key elements in vascular homeostasis. Their function is regulated by estrogens and estrogen receptors (ERs), but the effect of estrogenic compounds such as bisphenol A (BPA; an agonist of ER-β and agonist and antagonist of ER-α) and (R,R)-5,11-diethyl-5,6,11,12-tetrahydro-2,8-chrysenediol (THC; an agonist of ER-α and antagonist of ER-β) on human EPCs is unknown. We analyzed whether BPA and THC influence the migration of human EPCs, an essential process in endothelial regeneration, in both male and female EPCs.', 'EPCs isolated from healthy adult men and women were assayed for ER expression by Western blotting and chemotaxis assay.', 'Male and female EPCs similarly expressed ERs and did not differ in basal migration. Interestingly, 17-β-estradiol (10(-9) and 10(-10) M) significantly inhibited migration in female EPCs but not in males. Moreover, both 10(-5) M THC and 10(-8) M BPA blocked migration in female EPCs, allowing us to hypothesize that the effect is mediated by ER-α.
