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: Weight-loss is a near societal obsession and many diet programs use significant calorie restriction including fasting/short term starvation to generate rapid effects. Fasting is also a well-recognized cause of immunosuppression especially within the innate immune system. In this study, we sought to determine if the IL-1 arm of the neuroimmune system was down-regulated by a 24\u2009h fast and how fasting might generate this effect.', 'Mice were allowed ad libitum access to food or had food withheld for 24\u2009h. Expression of the endogenous IL-1 antagonists, IL-1 receptor type 2 (IL-1R2), and IL-1 receptor antagonist (IL-1RA) was determined as were sickness behaviors before and after IL-1β administration.', 'Fasting markedly increased gene expression of IL-1R2 (83-fold in adipose tissue, 9.5-fold in liver) and IL-1RA (68-fold in liver). Fasted mice were protected from IL-1β-induced weight-loss, hypoglycemia, loss of locomotor, and social anxiety. These protections were coupled to a large positive interaction of fasting and IL-1β on IL-1R2 gene expression in adipose tissue and liver (2.6- and 1.6-fold, respectively). Fasting not only increased IL-1RA and IL-1R2 protein 2.5- and 3.2-fold, respectively, in liver but also increased IL-1R2 1.8-fold in adipose tissue. Fasting, in turn, triggered a 2.4-fold increase in plasma free-fatty acids (FFAs) and a 2.1-fold increase in plasma corticosterone. Inhibition, of glucocorticoid action with mifepristone did not impact fasting-dependent IL-1R2 or IL-1RA gene expression. Administration of the FFA, palmitate, to mice increased liver IL-1R2 and IL-1RA gene expression by 14- and 11-fold, respectively.

Q: To compare the efficacy of intensity-modulated radiotherapy, three-dimensional conformal radiotherapy, and conventional radiotherapy for cervical cancer treatment.', 'Whole pelvis intensity-modulated radiotherapy, three-dimensional conformal radiotherapy, and conventional radiotherapy plans were designed for 16 patients with stage IIB cervical cancer, each using the prescribed dose of 50.4 Gy/28 fractions. Dose-volume histograms of the target volume and organs at risk were evaluated.', 'Compared to the 3D conformal and conventional radiotherapy plans, the intensity-modulated radiotherapy plan demonstrated superior conformal treatment. The mean planning target volume dose of all three plans reached the target effective therapeutic dose. The planning target volume dose of the intensity-modulated radiotherapy plan was significantly higher than that of either the three-dimensional conformal radiotherapy or conventional radiotherapy plan (P<0.05). When more than 30 Gy was administered in intensity-modulated radiotherapy, organs at risk including the small intestine, rectum, bladder, and bone marrow received a significantly reduced volume of radiation. In comparison of the average planning target volume doses, significant volume reductions in irradiation of organs at risk were obtained with full bladders.

Q: The cerebral microvascular occlusion elicits microvascular injury which mimics the different degrees of stroke severity observed in patients, but the mechanisms underlying these embolic injuries are far from understood. The Fas ligand (FasL)-Fas system has been implicated in a number of pathogenic states. Here, we examined the contribution of microglia-derived FasL to brain inflammatory injury, with a focus on the potential to suppress the FasL increase by inhibition of the P2X(7)-FasL signaling with pharmacological or genetic approaches during ischemia.', 'The cerebral microvascular occlusion was induced by microsphere injection in experimental animals. Morphological changes in microglial cells were studied immunohistochemically. The biochemical analyses were used to examine the intracellular changes of P2X(7)/FasL signaling. The BV-2 cells and primary microglia from mice genetically deficient in P2X(7) were used to further establish a linkage between microglia activation and FasL overproduction.', 'The FasL expression was continuously elevated and was spatiotemporally related to microglia activation following microsphere embolism. Notably, P2X(7) expression concomitantly increased in microglia and presented a distribution pattern that was similar to that of FasL in ED1-positive cells at pathological process of microsphere embolism. Interestingly, FasL generation in cultured microglia cells subjected to oxygen-glucose deprivation-treated neuron-conditioned medium was prevented by the silencing of P2X(7). Furthermore, FasL induced the migration of BV-2 microglia, whereas the neutralization of FasL with a blocking antibody was highly effective in inhibiting ischemia-induced microglial mobility. Similar results were observed in primary microglia from wild-type mice or mice genetically deficient in P2X(7). Finally, the degrees of FasL overproduction and neuronal death were consistently reduced in P2X(7)(-/-) mice compared with wild-type littermates following microsphere embolism insult.
