[EX Q]: Question: Does converging evidence implicate the abnormal microRNA system in schizophrenia?
Answer: Collectively, results from all 3 lines of evidence, suggest that the genetically based dysregulation of miRNA systems undermines miRNAs' inhibitory effects, resulting in the abnormal upregulation of genome transcription in the development of SZ.
[EX A]: yes

[EX Q]: Question: Does short-term , high-dose glucocorticoid treatment contribute to reduced bone mineral density in patients with multiple sclerosis?
Answer: Reduced BMD was prevalent in patients with MS. GC treatment appears not to be the primary underlying cause of secondary osteoporosis in MS patients.
[EX A]: no

[EX Q]: Question: Does granulocyte colony-stimulating factor prevent loss of spermatogenesis after sterilizing busulfan chemotherapy?
Answer: These results demonstrate that G-CSF protects spermatogenesis from gonadotoxic insult (busulfan) in rodents, and this may occur via direct action on CSF3R+ undifferentiated spermatogonia. G-CSF treatment might be an effective adjuvant therapy to preserve male fertility in cancer patients receiving sterilizing treatments.
[EX A]:
yes
