Ethnic inequality, multimorbidity and psychosis: can a syndemic framework resolve disputed evidence?

Syndemic theory is described as population-level clustering or co-occurrence of health conditions in the context of shared aetiologies that interact and can act synergistically. These influences appear to act within specific places of high disadvantage. We suggest ethnic inequality in experiences and outcomes of multimorbidity, including psychosis, may be explained through a syndemic framework. We discuss the evidence for each component of syndemic theory in relation to psychosis, using psychosis and diabetes as an exemplar. Following this, we discuss the practical and theoretical adaptations to syndemic theory in order to apply it to psychosis, ethnic inequality and multimorbidity, with implications for research, policy, and practice

Temperature dependent photoluminescence of organic semiconductors with varying backbone conformation

We present photoluminescence studies as a function of temperature from a series of conjugated polymers and a conjugated molecule with distinctly different backbone conformations. The organic materials investigated here are: planar methylated ladder type poly para-phenylene, semi-planar polyfluorene, and non-planar para hexaphenyl. In the longer-chain polymers the photoluminescence transition energies blue shift with increasing temperatures. The conjugated molecules, on the other hand, red shift their transition energies with increasing temperatures. Empirical models that explain the temperature dependence of the band gap energies in inorganic semiconductors can be extended to explain the temperature dependence of the transition energies in conjugated molecules.Comment: 8 pages, 9 figure

Generalized Second Law and phantom Cosmology: accreting black holes

The accretion of phantom fields by black holes within a thermodynamic context is addressed. For a fluid violating the dominant energy condition, case of a phantom fluid, the Euler and Gibbs relations permit two different possibilities for the entropy and temperature: a situation in which the entropy is negative and the temperature is positive or vice-versa. In the former case, if the generalized second law (GSL) is valid, then the accretion process is not allowed whereas in the latter, there is a critical black hole mass below which the accretion process occurs. In a universe dominated by a phantom field, the critical mass drops quite rapidly with the cosmic expansion and black holes are only slightly affected by accretion. All black holes disappear near the big rip, as suggested by previous investigations, if the GSL is violated.Comment: 8 pp., no figure

Suzaku Reveals Helium-burning Products in the X-ray Emitting Planetary Nebula BD+303639

BD+303639, the brightest planetary nebula at X-ray energies, was observed with Suzaku, an X-ray observatory launched on 2005 July 10. Using the X-ray Imaging Spectrometer, the K-lines from C VI, O VII, and O VIII were resolved for the first time, and C/O, N/O, and Ne/O abundance ratios determined. The C/O and Ne/O abundance ratios exceed the solar value by a factor of at least 30 and 5, respectively. These results indicate that the X-rays are emitted mainly by helium shell-burning products.Comment: 12 pages, 4 figures, accepted for publication in The Astrophysical Journal Letter

Ajuste de modelos não lineares no estudo de associação entre polimorfismos genéticos e o crescimento em bovinos de corte.

Foram utilizados dados de peso ao nascimento, ao desmame e mensais dos 8 aos 19 meses de idade de 11 classes de genótipos formadas pela concatenação dos polimorfismos genéticos da kappa-caseína-HinfI (CSN3): AA e AB, do hormônio do crescimento-AluI (GH): LL e LV e da b-lactoglobulina-HaeIII (LGB): AA, AB e BB. As informações foram obtidas de animais de três grupos genéticos: ½Canchim-Nelore (CN), ½Angus-Nelore (AN) e ½Simental-Nelore (SN), nascidos em 1998 e 1999 e pertencentes à Embrapa Pecuária Sudeste, São Carlos, SP. Dos cinco modelos estudados: Brody, Von Bertalanffy, Richards, Gompertz e Logístico, o último apresentou melhor qualidade do ajuste. As estimativas dos parâmetros A (valor assintótico), k (taxa de maturação) e m (ponto de inflexão) obtidas do modelo Logístico, ajustado para descrever o crescimento de cada animal, foram analisadas pelo método dos quadrados mínimos, por meio de um modelo linear, que incluiu além da média geral, os efeitos de genótipo, ano de nascimento, sexo e manejo alimentar. Para os animais do grupo genético CN, os genótipos influenciaram significativamente as estimativas dos parâmetros A e k da curva de crescimento. O genótipo AALLBB apresentou valor inferior de A e superior de k em relação aos genótipos ABLLAB e ABLLBB. A aplicação da técnica de modelos não lineares em estudos de associação entre polimorfismos genéticos e o crescimento proporcionou uma análise detalhada do desenvolvimento dos animais de diferentes genótipos estudados
