TASK DEFINITION: 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.
PROBLEM: To evaluate the effect of uterine leiomyomas on the endometrium using molecular markers of endometrial receptivity: HOXA10, HOXA11, LIF, and BTEB1.', 'Case-control study.', 'University medical center.', 'Thirty reproductive-aged women with submucosal, intramural, or no uterine myomas who underwent hysteroscopy or hysterectomy.', 'Proliferative phase endometrial sampling was performed at the time of surgery. In uteri with a submucosal myoma, directed endometrial biopsies were obtained over the myoma and over normal myometrium.', 'Endometrial HOXA10 expression was evaluated as a primary endpoint using quantitative real-time reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemistry. HOXA11, BTEB1, and LIF were evaluated using real-time RT-PCR.', 'Endometrial HOXA10 and HOXA11 messenger RNA (mRNA) expression were significantly decreased in uteri with submucosal myomas compared with controls and with uteri with intramural myomas. A similar trend was seen in BTEB1 mRNA expression; however, no difference was found in LIF mRNA expression. Immunohistochemistry localized the decrease in endometrial HOXA10 protein expression to stroma. In the presence of a submucosal myoma, there were no regional differences in gene expression.

PROBLEM: The main objective of the present study was the investigation of possible influence of lens opacification on macular pigment optical density (MPOD) measurements.', 'Eighty-six eyes of 64 patients (mean age 73.4 ± 8.3 years) were included in the study. MPOD was prospectively measured using the one-wavelength reflection method (Visucam500, Carl Zeiss Meditec AG) before and after cataract extraction, with implantation of a blue-light filtering intraocular lens (AlconSN60WF). The median of the maximum optical density (MaxOD) and the median of the mean optical density (MeanOD) measurements of macular pigment across the subject group were evaluated.', 'Statistically significant differences were noticed between pre-operative and post-operative measurements, the absolute values were generally lower after cataract extraction. The following median (lower/upper quartile) differences across the group were determined: MaxOD -33.8 % (-46.2 to -19.1 %), MeanOD -44.0 % (-54.6 to -26.6 %). Larger changes were observed in elderly patients [<70 years of age (n\u2009=\u200925 eyes): MaxOD -13.4 % (-20.5 to 3.6 %), MeanOD -23.6 % (-30.5 to -15.3 %) versus patients ≥70 years (n\u2009=\u200961 eyes) MaxOD -40.5 % (-53.2 to -30.1 %), MeanOD -47.2 % (-57.8 to -40.1 %)] and in patients with progressed stage of cataract. MaxOD for lens opacification grade 1 (n\u2009=\u20099 eyes): -27.4 % (-42.1 to -19.6 %), grade 2 (n\u2009=\u200926 eyes): -35.0 % (-44.2 to -25.3 %), grade 3 (n\u2009=\u200921 eyes): -34.4 % (-45.4 to -11.4 %), grade 4 (n\u2009=\u200925 eyes): -32.6 % (-53.2 to -6.4 %), and grade 5 (n\u2009=\u20095 eyes): -53.5 % (-61.7 to -38.7 %) and MeanOD for cataract stage 1 (n\u2009=\u20099 eyes): -42.6 % (-46.0 to -26.0 %), stage 2 (n\u2009=\u200926 eyes): -44.1 % (-51.8 to -26.2 %), stage 3 (n\u2009=\u200921 eyes): -45.7 % (-54.7 to -24.7 %), stage 4 (n\u2009=\u200925 eyes): -39.5 % (-59.4 to -26.1 %), and stage 5 (n\u2009=\u20095 eyes): -57.0 % (-66.1 to -51.4 %).
