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.

[EX Q]: 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?
[EX A]: 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.

[EX Q]: Context: Mucosal human papillomaviruses (HPV) are a major cause of cancers and papillomas of the anogenital and oropharyngeal tract. HPV-vaccination elicits neutralising antibodies in sera and cervicovaginal secretions and protects uninfected individuals from persistent anogenital infection and associated diseases caused by the vaccine-targeted HPV types. Whether immunisation can prevent oropharyngeal infection and diseases and whether neutralising antibodies represent the correlate of protection, is still unclear.', 'We determined IgG and neutralising antibodies against low-risk HPV6 and high-risk HPV16/18 in sera and oral fluids from healthy females (n=20) before and after quadrivalent HPV-vaccination and compared the results with non-vaccinated controls.', 'HPV-vaccination induced type-specific antibodies in sera and oral fluids of the vaccinees. Importantly, the antibodies in oral fluids were capable of neutralising HPV pseudovirions in vitro, indicating protection from infection. The increased neutralising antibody levels against HPV16/18 in sera and oral fluids post-vaccination correlated significantly within an individual.\Question: Does human papillomavirus vaccination induce neutralising antibodies in oral mucosal fluids?
[EX A]: We provide experimental proof that HPV-vaccination elicits neutralising antibodies to the vaccine-targeted types in oral fluids. Hence, immunisation may confer direct protection against type-specific HPV infection and associated diseases of the oropharyngeal tract. Measurement of antibodies in oral fluids represents a suitable tool to assess vaccine-induced protection within the mucosal milieu of the orophayrynx.

[EX Q]: Context: Recent studies have indicated a protective role of physiological autophagy in ischemic heart disease. However, the underlying mechanisms of autophagy regulation after ischemia are poorly understood. Exosomes are nano-sized vesicles released from cells that play critical roles in mediating cell-to-cell communication through the transfer of microRNAs. In this study, we observed that miR-30a was highly enriched in exosomes from the serum of acute myocardial infarction (AMI) patients in vivo and culture medium of cardiomyocytes after hypoxic stimulation in vitro. We also found that hypoxia inducible factor (HIF)-1 regulates miR-30a, which efficiently transferred via exosomes between cardiomyocytes after hypoxia. Inhibition of miR-30a or release of exosomes increased the expression of the core autophagy regulators beclin-1, Atg12, and LC3II/LC3I, which contributed to maintaining the autophagic response in cardiomyocytes after hypoxia. Taken together, the present study showed that exosomes from hypoxic cardiomyocytes regulate autophagy by transferring miR-30a in a paracrine manner, which revealed a new pathway of autophagy regulation that might comprise a promising strategy to treat ischemic heart disease.\Question: Does exosomal transfer of miR-30a between cardiomyocytes regulate autophagy after hypoxia?
[EX A]:
miR-30a is highly enriched in exosomes from the serum of AMI patients. Hypoxia induces miR-30a upregulation and enrichment into exosomes. MiR-30a is efficiently transferred via exosomes between hypoxic cardiomyocytes. Inhibition of exosome release contributes to maintaining of autophagy after hypoxia. Inhibition of miR-30a augments autophagy after hypoxia.
