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.

Q: Recent studies suggest that the inconsistent outcomes of patellofemoral pain (PFP) treatment may result from the unclear understanding of changes in the structures remote from the knee joint. Due to the crucial influence of core stability on the knee function, this study aimed to evaluate the recruitment pattern of core muscles in individuals with and without PFP.', 'Sixty women aged 18 to 40years, including 30 subjects diagnosed with PFP and 30 healthy controls rose on to their toes as quickly and strongly as possible in response to a sound alarm in standing position. Electromyographic onsets of the transversus abdominis (TrA)/internal oblique (IO), erector spinae (ES), and gluteus medius (GM) muscles were expressed relative to the electromyographic onset of the prime mover (i.e. soleus). Independent t-tests were performed to compare the onsets of each muscle between the groups. The nonparametric Friedman test and the post-hoc of Wilcoxon signed-rank test were used to describe the muscle activation pattern within the groups.', 'The results revealed different recruitment patterns of the core muscles between the groups. In the healthy group the GM and TrA/IO contracted, almost simultaneously, in anticipation of the prime mover contraction (sol). However, in PFP subjects a significant delay in the contraction of TrA/IO changed the pattern of muscle activation.

Q: Gap junction channels provide for direct electrical coupling between cells, and play an important role in homeostasis and electrical coupling. One of the proteins that form gap junctions, Connexin40 (Cx40), shows restricted expression in the body, and is found in blood vessels and in the atrium and conduction system of the heart. We have investigated whether gap junction channels formed of Cx40 are modulated by protein-kinase-A-mediated phosphorylation.', 'A communication-deficient human hepatoma cell line (SKHep1) was stably transfected with human Cx40 cDNA and the properties of Cx40 gap junctions channels and their modulation by cAMP were analyzed using immunocytochemistry, Western blotting, dual patch clamp, and dye coupling.', 'Administration of 1 mM 8-Br-cAMP resulted in a mobility shift of Cx40 protein on western blot and increased macroscopic gap junctional conductance between cell pairs by 46.2 +/- 12.0% (mean +/- S.E.M., n = 8). Under control conditions, single channel experiments revealed three single channel conductances around 30, 80 and 120 pS. When cAMP was added, channel conductances of 46 and 120 pS were observed. In monolayers, cAMP also increased the permeability of Cx40 gap junction channels for Lucifer Yellow by 58%.

Q: Panniculectomy integrated into pelvic procedures mandated in morbidly obese patients is a well described technique. Nevertheless, the abdominal cavity in such patients is generally approached through a vertical incision, frequently by forcibly pulling the panniculus inferiorly. Such a vertical approach has been associated with significant wound morbidity.', 'Patients were offered removal of excess abdominal skin without cosmetic intent. The mean weight of patients was 126 kg and the body mass index ranged from 29.4 to 59.9. The object of this study was to discover whether or not operative access was facilitated and whether or not wound morbidity was reduced. Fifteen patients had significant medical problems and nine of the 16 had an umbilical hernia.', 'Removal of the panniculus seemed to facilitate access to the abdomen, provided excellent exposure, and certainly allowed ready repair of the umbilical hernia with a Blake technique. All but one of the wounds healed by first intention, and in that patient, an 8 cm segment was easily resutured. The operative time was acceptable. There was no increased blood loss associated with the panniculectomy, but of note is the fact that the hematocrit level decreased in five patients on days 2 to 5 postoperatively without hematoma formation.
