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.

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?

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.

Q: Context: Several Northern Hemisphere Drosera species have been used in the therapy of respiratory tract infections as the traditional medicine Droserae Herba.', 'To determine the anti-inflammatory effects of Drosera species and to investigate a substitute material for Droserae Herba, we examined the effect of extracts of Drosera rotundifolia, Drosera tokaiensis and Drosera spatulata on activated T cell membrane (aTc-m)-induced inflammatory gene expression in HMC-1 human mast cells.', 'Drosera rotundifolia, Drosera spatulata and Drosera tokaiensis were collected in Japan. Herbs were extracted with 80% EtOH, and subsequently applied to OASIS HLB column. HMC-1 cells were treated with each Drosera column-adsorbed fraction for 15min, and subsequently added to aTc-m and incubated for 16h. Inflammatory gene and protein expressions were determined by DNA microarray, RT-PCR and Western blotting.', 'Drosera rotundifolia and Drosera tokaiensis fractions, but not the Drosera spatulata fraction, suppressed inflammatory gene expression induced by aTc-m in HMC-1 cells.\Question: Do drosera rotundifolia and Drosera tokaiensis suppress the activation of HMC-1 human mast cells?

A: Drosera rotundifolia and Drosera tokaiensis suppressed activation of HMC-1 cells induced by aTc-m. Since the Drosera tokaiensis fraction was more effective than the traditionally used Drosera rotundifolia, Drosera tokaiensis is a likely substitute as a source of Droserae Herba.

Q: Context: Accumulation of acetylcholine in the central nervous system is believed to account for the rapid lethality of organophosphate pesticides and chemical nerve agents. Diazepam is known to supplement atropine therapy, but its specific mechanism of action is uncertain.', 'To test four centrally acting agents for early antidotal efficacy in severe dichlorvos poisoning in the murine model.', 'The up-and-down method was used to dose four candidate antidotes: diazepam, xylazine, morphine, and ketamine. Antidotes were administered subcutaneously to unsedated adult Sprague-Dawley rats who were pretreated with 3 mg/kg intraperitoneal glycopyrrolate. All animals received 20 mg/kg of dichlorvos subcutaneously 5 minutes later. A blinded observer adjudicated the outcomes of 10-minute mortality and survival time.', 'All animals pretreated with either no antidote (8/8 deaths) or glycopyrrolate alone (8/8) died within 10 minutes of dichlorvos injection. Pretreatment with diazepam (3/9 deaths), or xylazine (3/9), decreased lethality substantially (Fisher p = 0.007; median effective doses, 0.12 mg/kg and 3.0 mg/kg, respectively). Intermediate doses of morphine (3.1 to 5.5 mg/kg) resulted in survival, but higher doses did not, presumably because of excessive respiratory depression (7/11 deaths; p = 0.09). Ketamine (7/8 deaths) was ineffective as an antidote. Survival times also were prolonged in the diazepam and xylazine groups (log-rank p < 0.001) and, to a lesser degree, the morphine group (p = 0.07).\Question: Do multiple centrally acting antidotes protect against severe organophosphate toxicity?

A:
Doses of diazepam, xylazine, and morphine below those used for deep sedation protect against severe dichlorvos poisoning, implying that several distinct central mechanisms are each sufficient to avert lethality. These findings suggest new possibilities for prophylaxis or therapy.
