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.

Maternal nutrition during different stages of pregnancy can induce significant changes in the structure, physiology, and metabolism of the offspring. These changes could have important implications on food animal production especially if these perturbations impact muscle and adipose tissue development. Here, we evaluated the impact of different maternal isoenergetic diets, alfalfa haylage (HY; fiber), corn (CN; starch), and dried corn distillers grains (DG; fiber plus protein plus fat), on the transcriptome of fetal muscle and adipose tissues in sheep.', 'Prepartum diets were associated with notable gene expression changes in fetal tissues. In longissimus dorsi muscle, a total of 224 and 823 genes showed differential expression (FDR ≤0.05) in fetuses derived from DG vs. CN and HY vs. CN maternal diets, respectively. Several of these significant genes affected myogenesis and muscle differentiation. In subcutaneous and perirenal adipose tissues, 745 and 208 genes were differentially expressed (FDR ≤0.05), respectively, between CN and DG diets. Many of these genes are involved in adipogenesis, lipogenesis, and adipose tissue development. Pathway analysis revealed that several GO terms and KEGG pathways were enriched (FDR ≤0.05) with differentially expressed genes associated with tissue and organ development, chromatin biology, and different metabolic processes.

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 %).

To evaluate whether calcium adjusted for albumin can be used to monitor calcium homeostasis in critically ill patients.', 'Prospective single-single center observational study.', 'Clinical laboratory and critical care unit of a regional teaching hospital.', 'Fifty-three paired samples were from 36 patients requiring intensive care treatment.', 'None.', 'Total calcium, albumin-adjusted calcium, and ionized calcium were measured in critically ill patients during an 8-wk period. Calcium was adjusted for albumin using the formula that is most frequently used in The Netherlands. Using ionized calcium as the gold standard, albumin-adjusted calcium overestimated hypercalcemia and totally missed hypocalcemia. The same seemed to be true for other formulas used for albumin or protein adjustment of calcium concentrations.
