In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: Excessive infant crying, or infantile colic, is a common and often stress-inducing problem for parents that can ultimately result in child abuse. From previous research it is known that maternal depression is related to excessive crying, but so far little is known about the influence of paternal depression.', "In a prospective, population-based study, we obtained information on both maternal and paternal depressive symptoms at 20 weeks of pregnancy by using the Brief Symptom Inventory. Parental depressive symptoms were related to excessive crying in 4426 two-month-old infants. The definition of excessive crying was based on the widely used Wessel's criteria (ie, crying >3 hours for >3 days in the past week).", 'After adjustment for depressive symptoms of the mother and relevant confounders, we found a 1.29 (95% confidence interval: 1.09-1.52) higher risk of excessive infant crying per SD of paternal depressive symptoms.\Question: Are paternal depressive symptoms during pregnancy related to excessive infant crying?
Our findings indicate that paternal depressive symptoms during pregnancy might be a risk factor for excessive infant crying. This finding could be related to genetic transmission, interaction of a father with lasting depressive symptoms with the infant, or related indirectly through contextual stressors such as marital, familial, or economic distress.

Context: Talin-1 is a cytoskeleton protein that participates in cell migration and plays a role in tumor formation, migration, and metastasis in different types of cancer. Chinese investigators have observed that the levels of Talin-1 protein and mRNA expression in HCC tissues are significantly lower than in the adjacent non-cancerous tissue. However, Japanese investigators have reported that Talin-1 is upregulated in HCC. Tln2 as homologous gene of Tln-1, which encodes a very similar protein, but the role of Talin-2 is very little known in primary liver cancer (PLC). We investigated whether the expression of Talin-1 in PLC may be associated with the histological subtype as well as the role of Talin-1 in tumor cell invasion and migration using human hepatocellular carcinoma cell lines.', 'We measured the mRNA expression levels of Talin-1 and Talin-2 in five human liver cancer cell lines and normal human liver cell (LO2 cell line) by real-time PCR and the protein expression levels of Talin-1 by Western blot. Migration and invasion of the cells were assessed using transwell assays and cell scratch experiments, respectively, and proliferation was assessed by soft AGAR colony formation.', 'Talin-1 and Talin-2 expression differed significantly between the five human liver cancer cell lines and LO2 cell line (p<0.05). Compared with the LO2 cell line, the invasion and migration capabilities of the five cancer cell lines differed significantly (p<0.05). Similarly, the colony-forming ability differed (p<0.05).\Question: Does talin-1 correlate with reduced invasion and migration in human hepatocellular carcinoma cells?
High levels of Talin-1 expression are correlated with reduced invasion and migration as well as decreased malignancy in human liver cancer cell lines; the suppression of Talin-1 promotes invasion and migration. In addition, Talin-2 may be correlated with invasion and migration in human hepatocellular carcinoma.

Context: Contact of blood with artificial surfaces and air as well as ischemia/reperfusion injury to the heart and lungs mediate systemic and local inflammation during cardiopulmonary bypass (CPB). Activation of complement and coagulation cascades leads to and accompanies endothelial cell damage. Therefore, endothelial-targeted cytoprotection with the complement inhibitor and endothelial protectant dextran sulfate (DXS, MW 5000) may attenuate CBP-associated myocardial and pulmonary injury.', 'Eighteen pigs (DXS, n=10; phosphate buffered saline [PBS], n=8) underwent standard cardiopulmonary bypass. After aortic cross-clamping, cardiac arrest was initiated with modified Buckberg blood cardioplegia (BCP), repeated after 30 and 60 min with BCP containing either DXS (300 mg/10 ml, equivalent to 5mg/kg) or 10 ml of PBS. Following 30 min reperfusion, pigs were weaned from CPB. During 2h of observation, cardiac function was monitored by echocardiography and invasive pressure measurements. Inflammatory and coagulation markers were assessed regularly. Animals were then sacrificed and heart and lungs analyzed.', 'DXS significantly reduced CK-MB levels (43.4+/-14.8 ng/ml PBS, 35.9+/-11.1 ng/ml DXS, p=0.042) and significantly diminished cytokine release: TNFalpha (1507.6+/-269.2 pg/ml PBS, 222.1+/-125.6 pg/ml DXS, p=0.0071), IL1beta (1081.8+/-203.0 pg/ml PBS, 110.7+/-79.4 pg/ml DXS, p=0.0071), IL-6 (173.0+/-91.5 pg/ml PBS, 40.8+/-19.4 pg/ml DXS, p=0.002) and IL-8 (304.6+/-81.3 pg/ml PBS, 25.4+/-14.2 pg/ml DXS, p=0.0071). Tissue endothelin-1 levels were significantly reduced (6.29+/-1.90 pg/100mg PBS, 3.55+/-1.15 pg/100mg DXS p=0.030) as well as thrombin-anti-thrombin formation (20.7+/-1.0 microg/ml PBS, 12.8+/-4.1 microg/ml DXS, p=0.043). Also DXS reduced cardiac and pulmonary complement deposition, neutrophil infiltration, hemorrhage and pulmonary edema (measured as lung water content, 81+/-3% vs 78+/-3%, p=0.047), indicative of attenuated myocardial and pulmonary CPB-injury. Diastolic left ventricular function (measured as dp/dt(min)), pulmonary artery pressure (21+/-3 mmHg PBS, 19+/-3 mmHg DXS, p=0.002) and right ventricular pressure (21+/-1 mmHg PBS, 19+/-3 mmHg DXS p=0.021) were significantly improved with the use of DXS.\Question: Does addition of dextran sulfate to blood cardioplegia attenuate reperfusion injury in a porcine model of cardiopulmonary bypass?
Addition of DXS to the BCP solution ameliorates post-CPB injury and to a certain extent improves cardiopulmonary function. Endothelial protection in addition to myocyte protection may improve post-CPB outcome and recovery.
