The endophenotype concept was initially proposed to enhance the power of genetic studies of complex disorders. It is closely related to the genetic component in a liability-threshold model; a perfect endophenotype should have a correlation of 1 with the genetic component of the liability to disease. In reality, a putative endophenotype is unlikely to be a perfect representation of the genetic component of disease liability. The magnitude of the correlation between a putative endophenotype and the genetic component of disease liability can be estimated by fitting multivariate genetic models to twin data. A number of statistical methods have been developed for incorporating endophenotypes in genetic linkage and association analyses with the aim of improving statistical power. The most recent of such methods can handle multiple endophenotypes simultaneously for the greatest increase in power. In addition to increasing statistical power, endophenotype research plays an important role in helping to understand the mechanisms which connect the associated genetic variants with disease occurrence. Novel statistical approaches may be required for the analysis of the complex relationships between endophenotypes at different levels and how they converge to cause the occurrence of disease.

The recent identification of cardiac progenitor cells （CPCs） provides a new paradigm for studying and treating heart disease. To realize the full potential of CPCs for therapeutic purposes, it is essential to understand the genetic and epigenetic mechanisms guiding CPC differentiation into cardiomyocytes, smooth muscle, or endothelial cells. ATP-dependent chromatin remodelers mediate one critical epigenetic mechanism. These large multiprotein complexes open up chromatin to modulate transcription factor access to DNA. SWI/SNF, one of the major types of chromatin remodelers, plays a key role in various aspects of development （de la Serna et al., 2006; Wu et al., 2009）, including heart development and disease （Lickert et al., 2004; Wang et al., 2004; Huang et al., 2008; Stankunas et al., 2008; Hang et al., 2010）. In this review, we describe the specific function of various SWI/SNF components in cardiogenesis and cardiac progenitor cell （CPC） self-renewal and differentiation. We envision that a detailed understanding of the SWI/SNF in heart development and CPC formation and differentiation will generate novel insights into epigenetic mechanisms that govern CPC differentiation and may have significant implications in understanding and treating heart disease.

Amphibians show a variety of reproductive modes and strategies. The cyclicity and continuity of reproduction can often be predicted from the annual gonadosomatic index trends in a species specific manner. This research aims to document the female and male gonadosomatic index profiles and to ascertain the reproductive cyclicity or continuity of Fejervarya lirnnocharis （Anura： Ranidae） caught in Mac Sot, Tak Province, Thailand. Frogs were collected monthly between November 2007 and October 2009 in rice fields and their surrounding areas in the study site. For each frog, total weight and ovarian/testicular weight were measured to obtain the female and male gonadosomatic index. The number of female individuals with mature eggs （postvitellogenic eggs） was also counted. The results showed that female frogs had two main surges of increased GSI in March and September of 2008. Alternatively, male frogs showed a more gradual increase and decrease in gonadosomatic index, thus the index remaining high throughout the year. This study concluded that while F. limnocharis in this area is essentially a continuous breeder, it is more optimized for a cyclic reproduction mode with two breeding cycles during the rainy season.

The study of endophenotypes may be a viable strategy to tackle the genetic complexity and phenotypic heterogeneity of psychosis, but this research direction is relatively under-developed in China as compared to Western countries. We have recently initiated one of the first family studies of endophenotypes for psychosis in China. Patients entering an established early psychosis intervention service are recruited into this research project for phenotyping, endophenotyping and genotyping. At the endophenotypic level, four domains (neurological soft signs, neurocognition of prospective memory, social cognition of facial emotion recognition, and affective cognition of anticipatory and consummatory pleasure) are studied in the sample of patients with psychosis and their unaffected siblings. This article illustrates the benefit of a research-oriented clinical programme and its findings based on the data collected as of early 2011.

Gunshot injuries are rather serious but uncommon type of trauma in India. Radiologists can contribute substantially in evaluation and treatment of patients with a gunshot wounds. Plain films, CT, Angiography, and sometimes MR imaging are used to localize shots. This paper describes a case report of shotgun injury to the face and neck and also attempts to illustrate the spectrum of available imaging with relevant findings pertaining to bullets and shotgun pellets in gunshot injuries. Radiologists should be aware of the associated complications and forensic implications when they take on the task of interpreting these images.
