Question: Question: Is childhood maltreatment associated with depression but not with hypochondriasis in later life?
Answer: The findings suggest a robust association of childhood maltreatment with depression but not with hypochondriasis. This result does not support etiological models of hypochondriasis which rely on childhood maltreatment as a risk factor for the development of this disorder.

Answer: yes

Question: Question: Do tECPR2 mutations cause a new subtype of familial dysautonomia like hereditary sensory autonomic neuropathy with intellectual disability?
Answer: We suggest that the disease should therefore be classified as a new subtype of hereditary sensory-autonomic neuropathy. The discovery of additional mutations in non-Bukharian patients implies that this disease might be more common than previously appreciated and should therefore be considered in undiagnosed cases of intellectual disability with autonomic features and respiratory symptoms regardless of demographic origin.

Answer: yes

Question: Question: Does fluorescent labelling of intestinal epithelial cells reveal independent long-lived intestinal stem cells in a crypt?
Answer: The use of our original lentiviral transgene system to mark individual organoid crypt stem cells showed that long-lived plural crypt stem cells might independently serve as intestinal epithelial cells, resulting in the formation of a completely functional villus.

Answer:
yes
