Input: Consider Input: Context: Hyaluronic acid binding protein 1 (HABP1), a family of proteins interacting with hyaluronan (HA), had been associated with cell adhesion and tumor invasion. The aim of this study was to investigate the correlation between clinicopathologic factors and patient survival time with the expression of HABP1 in breast cancer patients.', 'Expression of HABP1 mRNA and protein were detected with real-time quantitative PCR and immunohistochemical staining in 63 breast cancer and non-cancerous matched tissues.', "The mRNA expression level of HABP1 was unrelated to the patient's age, tumor size, histological grade, TNM stage. However, it proved to be positively related to axillary nodes metastasis (P = 0.008). Furthermore, it was shown that the survival rate of patients with low HABP1 expression was significantly higher than that of patients with high HABP1 expression (P = 0.025). Multivariate analysis revealed that HABP1 mRNA expression level was a significant factor for predicting prognosis (P = 0.022). The immunohistochemistry results showed that the expression level of HABP1 in breast cancer cells was higher than that in normal breast cells.
Answer: HABP1 might be an independent predictive factor for breast cancer prognosis and up-regulation of HABP1 might play an important role in the metastasis of breast cancer.

Output: Is increased expression of hyaluronic acid binding protein 1 correlated with poor prognosis in patients with breast cancer?


Input: Consider Input: Context: The aim of this study was to compare the efficacy of surgery for spontaneous intracerebral hemorrhage with that of medical treatment, based on data from the Japan Stroke Registry Study.', 'From 1999 to 2001, 1010 patients with spontaneous intracerebral hemorrhage were registered in the Japan Standard Stroke Registry Study from 45 stroke center hospitals in Japan. The National Institutes of Health Stroke Scale (NIHSS), Japan Stroke Scale (JSS), and modified Rankin Scale scores were used to compare severity and improvement in patients given surgical and medical treatment.
Answer: Surgically treated patients, especially those with cerebellar hemorrhage, had significantly greater improvement in NIHSS or JSS score compared with medically treated patients. Our findings indicated that the patients who underwent surgery appeared to have better outcomes. But, because the study was not randomized, this observation cannot be interpreted as indicating that surgery is advantageous.

Output: Does surgery for spontaneous intracerebral hemorrhage have greater remedial value than conservative therapy?


Input: Consider Input: Context: The observation of intact non-covalent complexes by electrospray ionization mass spectrometry (ESI-MS) hinges on the ability to minimize in-source activation processes that take place during analyte desolvation. We explored the merits of replacing the sampling cone of a standard Z-spray source with a heated capillary that makes the desolvation process slower and more gradual. We employed well-characterized protein-RNA, RNA-RNA, and DNA-DNA assemblies to compare the alternative configurations.', 'Mass analysis evaluated the integrity of the complexes, whereas traveling wave ion mobility experiments assessed the stability of biomolecular structure. Analyses were performed back-to-back on the same samples on a Synapt G2 HDMS equipped with either the standard sampling cone or the heated-capillary apparatus. In each configuration, the source/capillary temperature was varied in controlled fashion, while keeping all other desolvation parameters constant to monitor the in-source dissociation of selected DNA duplexes. Ion mobility data were obtained from the same precursor by using the alternative configurations under the same settings.', 'Monitoring the percentage of associated complex demonstrated that the heated capillary provided softer desolvation that was more conducive to the detection of intact non-covalent interactions. This configuration failed to produce complete dissociation of 14\u2009bp and 24\u2009bp duplexes, even when the source/capillary temperature was increased well above their solution melting points. Analyzed by IMS-MS, a selected construct displayed just one conformation with the heated capillary, but two with the standard sampling cone.
Answer: The heated capillary minimizes in-source activation processes that can lead to unintended dissociation of complexes and perturbation of biomolecular structure, which rely on the integrity of non-covalent interactions. This effect can be attributed to the attenuation of the supersonic expansion typical of the Z-spray geometry and the greater ability to control the energy imparted to the system. This hardware modification will be expected to benefit the analysis of biomolecular structure performed on this particular instrumental platform.


Output: Does a simple heated-capillary modification improve the analysis of non-covalent complexes by Z-spray electrospray ionization?
