In typically developed subjects, such coupling occurs at the right posterior temporal sulcus (pSTS) for frequencies below 1 Hz, and reflects the neural processing of sentence-level rhythmic prosody at the prelexical level.
Methods: Cortical neuromagnetic signals were recorded with MEG (Elekta Oy, Finland) while seven right-handed and native French-speaking ASD subjects (six males, BI 6727 research buy one female, range: 13-20 years) listened to live (Live) or recorded (Recorded) voices continuously reading a text in French for five minutes. Coherence was computed between the reader’s voice time-course and ASD subjects’ MEG signals. Coherent neural sources were subsequently reconstructed using a beamformer. Key findings: Significant coupling was found at 0.5 Hz in all ASD subjects in Live and in six subjects in Recorded. Coherent sources were located close to the right pSTS in both conditions. No significant difference was found in
coherence levels between Live and Recorded, and between ASD subjects and ten typically developed subjects (right-handed, native French-speaking adults, 5 males, 5 females, age range: 21-38 years) included in a previous study. Significance: This study discloses a preserved OSI-744 inhibitor coupling between the reader’s voice and ASD subjects’ cortical activity at the right pSTS. These findings support the existence of preserved neural processing of sentence-level rhythmic prosody in ASD. The preservation of early cortical processing of prosodic elements in verbal language might be exploited in therapeutic interventions in ASD.”
“Background: Although elevated risks of pancreatic cancer have been observed in long-term survivors of Hodgkin lymphoma
(HL), no prior study has assessed the risk of second pancreatic cancer in relation to radiation dose and specific chemotherapeutic agents. Patients and methods: We conducted an international case-control study within a cohort of 19 882 HL survivors diagnosed from 1953 to 2003 including 36 cases and 70 matched controls. Results: Median ages at HL and pancreatic cancer diagnoses were 47 and 60.5 years, respectively; median time to pancreatic cancer was 19 years. Pancreatic cancer risk increased with increasing NU7441 radiation dose to the pancreatic tumor location (P-trend = 0.005) and increasing number of alkylating agent (AA)-containing cycles of chemotherapy (P-trend = 0.008). The odds ratio (OR) for patients treated with both subdiaphragmatic radiation ( bigger than = 10 Gy) and bigger than = 6 AA-containing chemotherapy cycles (13 cases, 6 controls) compared with patients with neither treatment was 17.9 (95% confidence interval 3.5-158). The joint effect of these two treatments was significantly greater than additive (P = 0.041) and nonsignificantly greater than multiplicative (P = 0.29). Especially high risks were observed among patients receiving bigger than = 8400 mg/m(2) of procarbazine with nitrogen mustard or bigger than = 3900 mg/m(2) of cyclophosphamide.
