The reactions of trimethylindium (TMIn) with HN3 and NH3 are relevant to the chemical vapor deposition of indium nitride thin film. The mechanisms and energetics of these reactions in the gas phase have been investigated by density functional theory and ab initio calculations using the CCSD(T)/Lanl2dz//B3LYP/Lanl2dz and CCSD(T)/Lanl2dz//MP2/Lanl2dz methods. The results of both methods are in good agreement for the optimized geometries and relative energies. These results suggest that the reaction with HN3 forms a new stable product, dimethylindiumnitride, CH3-InN-CH3 via another stable In(CH3)(2)N-3 (dimethylindium azide, DMInA) intermediate. DMInA may undergo unimolecular decomposition to form CH3InNCH3 by two main possible pathways: (1) a stepwise decomposition process through N-2 elimination followed by CH3 migration from In to the remaining N atom and (2) a concerted process involving the concurrent CH3 migration and N-2 elimination directly giving N-2 + CH3InNCH3. The reaction of TMIn with NH3 forms a most stable product DMInNH2 following the initial association and CH4-elimination reaction. The required energy barrier for the elimination of the second CH4 molecule from DMInNH2 is 74.2 kcal/mol. Using these reactions, we predict the heats of formation at 0 K for all the products and finally for InN which is 123 +/- 1 kcal/mol predicted by the two methods. The gas-phase reaction of HN3 with TMIn is compared with that occurring on rutile TiO2 (110). The most noticeable difference is the high endothermicity of the gas-phase reaction for InN production (53 kcal/mol) and the contrasting large exothermicity (195 kcal/mol) released by the low-barrier Langmuir-Hinshelwood type processes following the adsorption of TMIn and HN3 on the surface producing a horizontally adsorbed InN(a), Ti-NIn-O(a), and other products, CH4(g) + N-2(g) + 2CH(3)O(a) [J. Phys. Chem. B 2006, 110, 2263].

Objectives: To evaluate the incidence rates and risk of sudden sensorineural hearing loss among patients with depressive disorders. Method: Data for 27 547 patients with newly diagnosed depressive disorders and 27 547 subjects without depressive disorders between 2001 and 2008 were yielded from the Taiwan National Health Insurance Research Database. Sudden sensorineural hearing loss incidence at the end of 2011 was determined. Cumulative incidence and adjusted hazard ratio were computed. Results: Sudden sensorineural hearing loss incidence was 1.45 times higher in the depressive disorders group compared to the non-depressive disorders group (p = 0.0041), with an adjusted hazard ratio of 1.460. A significant increased risk of developing sudden sensorineural hearing loss was noted in patients with diabetes mellitus, chronic kidney disease and hyperlipidaemia (p < 0.05). Conclusion: The results suggest an increased risk of developing sudden sensorineural hearing loss in patients with depressive disorders. Co-morbidities such as diabetes mellitus, chronic kidney disease and hyperlipidaemia significantly aggravated the risk. Depressive disorders might be considered a risk factor for sudden sensorineural hearing loss. It remains to be seen whether control of depressive disorders can decrease the incidence of sudden sensorineural hearing loss in patients with depressive disorders.

Background Late-life depression (LLD) in the elderly was reported to present with emotion dysregulation accompanied by high perceived loneliness. Previous research has suggested that LLD is a disorder of connectivity and is associated with aberrant network properties. On the other hand, perceived loneliness is found to adversely affect the brain, but little is known about its neurobiological basis in LLD. The current study investigated the relationships between the structural connectivity, functional connectivity during affective processing, and perceived loneliness in LLD. Method The current study included 54 participants aged >60 years of whom 31 were diagnosed with LLD. Diffusion tensor imaging (DTI) data and task-based functional magnetic resonance imaging (fMRI) data of an affective processing task were collected. Network-based statistics and graph theory techniques were applied, and the participants\' perceived loneliness and depression level were measured. The affective processing task included viewing affective stimuli. Results Structurally, a loneliness-related sub-network was identified across all subjects. Functionally, perceived loneliness was related to connectivity differently in LLD than that in controls when they were processing negative stimuli, with aberrant networking in subcortical area. Conclusions Perceived loneliness was identified to have a unique role in relation to the negative affective processing in LLD at the functional brain connectional and network levels. The findings increas our understanding of LLD and provide initial evidence of the neurobiological mechanisms of loneliness in LLD. Loneliness might be a potential intervention target in depressive patients.
