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.

Input: Consider Input: Infection with Leishmania parasites causes mainly cutaneous lesions at the site of the sand fly bite. Inflammatory metastatic forms have been reported with Leishmania species such as L. braziliensis, guyanensis and aethiopica. Little is known about the factors underlying such exacerbated clinical presentations. Leishmania RNA virus (LRV) is mainly found within South American Leishmania braziliensis and guyanensis. In a mouse model of L. guyanensis infection, its presence is responsible for an hyper-inflammatory response driven by the recognition of the viral dsRNA genome by the host Toll-like Receptor 3 leading to an exacerbation of the disease. In one instance, LRV was reported outside of South America, namely in the L. major ASKH strain from Turkmenistan, suggesting that LRV appeared before the divergence of Leishmania subgenera. LRV presence inside Leishmania parasites could be one of the factors implicated in disease severity, providing rationale for LRV screening in L. aethiopica.', 'A new LRV member was identified in four L. aethiopica strains (LRV-Lae). Three LRV-Lae genomes were sequenced and compared to L. guyanensis LRV1 and L. major LRV2. LRV-Lae more closely resembled LRV2. Despite their similar genomic organization, a notable difference was observed in the region where the capsid protein and viral polymerase open reading frames overlap, with a unique -1 situation in LRV-Lae. In vitro infection of murine macrophages showed that LRV-Lae induced a TLR3-dependent inflammatory response as previously observed for LRV1.

Input: Consider Input: Human breast tumors are heterogeneous and consist of phenotypically diverse cells. Breast cancer cells with a CD44+/CD24- phenotype have been suggested to have tumor-initiating properties with stem cell-like and invasive features, although it is unclear whether their presence within a tumor has clinical implications. There is also a large heterogeneity between tumors, illustrated by reproducible stratification into various subtypes based on gene expression profiles or histopathological features. We have explored the prevalence of cells with different CD44/CD24 phenotypes within breast cancer subtypes.', 'Double-staining immunohistochemistry was used to quantify CD44 and CD24 expression in 240 human breast tumors for which information on other tumor markers and clinical characteristics was available. Gene expression data were also accessible for a cohort of the material.', 'A considerable heterogeneity in CD44 and CD24 expression was seen both between and within tumors. A complete lack of both proteins was evident in 35% of the tumors, while 13% contained cells of more than one of the CD44+/CD24-, CD44-/CD24+ and CD44+/CD24+ phenotypes. CD44+/CD24- cells were detected in 31% of the tumors, ranging in proportion from only a few to close to 100% of tumor cells. The CD44+/CD24- phenotype was most common in the basal-like subgroup--characterized as negative for the estrogen and progesterone receptors as well as for HER2, and as positive for cytokeratin 5/14 and/or epidermal growth factor receptor, and particularly common in BRCA1 hereditary tumors, of which 94% contained CD44+/CD24- cells. The CD44+/CD24- phenotype was surprisingly scarce in HER2+ tumors, which had a predominantly CD24+ status. A CD44+/CD24- gene expression signature was generated, which included CD44 and alpha6-integrin (CD49f) among the top-ranked overexpressed genes.

Input: Consider Input: Acute Kidney Injury (AKI) is a serious early complications in patients with acute pancreatitis (AP) that signifcantly increases mortality rates compared to patients without AKI. The early diagnosis of AKI during its treatable phases and implementation of appropriate treatment protocols can improve outcomes for this group of patients. A promising biomarker for AKI is neutrophil gelatinase-associated lipocalin (NGAL).', 'This study evaluated the diagnostic value of NGAL concentrations in serum and in urine for patients developing AKI as an early complication of AP compared to AP patients without AKI.', 'The study group composed of 65 patients (34 men and 31 women) with a mean age of 62.2 ± 16 years with AP and hospitalized in the Surgery Department of the Direct Hospital in Sucha Beskidzka, Poland between January and December 2014. Serum NGAL (sNGAL) levels were measured with the BioVendor ELISA kit, and urine NGAL (uNGAL) with the Abbott ARCHITECT Analyzer.', 'In the early phase of AP, 11 patients (17%) developed AKI, including 10 patients with stage 1 and one with stage 2. AKI was associated with more severe AP, higher BISAP scores, the need for more intensive treatment, longer hospital stays and higher mortality. Both serum and urine NGAL concentrations were signifcantly higher in patients with AKI throughout the study and signifcantly predicted AKI in simple and multiple logistic regression adjusted for age, sex and comorbidities. Serum and urine NGAL concentrations were signifcantly correlated with levels of serum urea, creatinine, urine albumin, and the maximum change in serum creatinine. Serum and urine NGAL levels also correlated positively with direct neutrophil counts and CRP concentrations throughout the study.
