In males, sperm production begins at puberty and lasts throughout reproduct-ire life. This implies that a population of germ stem cells/progenitors must be main- tained, amplified and differentiate throughout life to enable the continuous supply of sperm. Spermatogenesis is indeed divided into three phases： a proliferative phase, a meiotic phase and a postmeiotic spermio- genic phase. In the proliferative phase, undifferentiated spermatogonia stem cells are divided to maintain the principle undiffer- entiated stern cell population on the one hand, and on the other hand to amplify and differentiate a fraction of the spermatogonia into primary spermatocytes.

This article examines the social and psychological function of the ＂scar＂ metaphor at the turn from the late 1970s to the early 1980s. We propose that the widely employed scar metaphor, which was first created in the scar literature movement of the late 1970s and early 1980s, enabled Chinese readers to ＂work through＂ the blend of psychological and ideological disquietude that lingered after the Cultural Revolution. We will first clarify how the scar metaphor facilitated this process of ＂working through,＂ using as an example Lu Xinhua＇s ＂The Scar＂（Shanghen）. We will then describe how the scar metaphor became dispersed throughout Chinese popular culture and enabled a broad spectrum of Chinese readers to participate in a similar process. At both levels of analysis, we will argue that the scar metaphor simultaneously provides a literary space for working through personal trauma and related anxieties about the ideological transition during this socio-political change.

High-resolution seismic reflections have been used effectively to investigate sinkholes formed from the dissolution of a bedded salt unit found throughout most of Central Kansas. Surface subsidence can have devastating effects on transportation structures. Roads, rails, bridges, and pipelines can even be dramatically affected by minor ground instability. Areas susceptible to surface subsidence can put public safety at risk. Subsurface expressions significantly larger than surface depressions are consistently observed on seismic images recorded over sinkholes in Kansas. Until subsidence reaches the ground surface, failure appears to be controlled by compressional forces evidenced by faults with reverse orientation. Once a surface depression forms or dissolution of the salt slows or stops, subsidence structures are consistent with a tensional stress environment with prevalent normal faults. Detecting areas of rapid subsidence potential, prior to surface failure, is the ultimate goal of any geotechnical survey where the ground surface is susceptible to settling. Seismic reflection images have helped correlate active subsidence to dormant paleofeatures, project horizontal growth of active sinkholes based on subsurface structures, and appraise the risk of catastrophic failure.

Colorectal liver metastases (CRLM) were traditionally associated with a very poor prognosis after resection, with some historical series reporting 5-year survival rates as low as 14% for completely resected multiple metastases (1). However, as modern chemotherapy and surgical techniques have evolved, there has been much progress made in improving survival for this unique group of patients, with 5-year survival approaching 55% with R0 resection (2). However, not all CRLM are the same, with very different biological behaviour and ultimately oncologic outcomes in different patients. There have been many attempts to create a scoring system defining factors which will predict this behaviour, with the system created by Fong et al. in 1999 being the most commonly employed (3). These scoring systems are important because they help the selection of patients who are likely to benefit from surgical treatment of their metastases. Patients who are unlikely to benefit from surgical resection may be better treated by alternative and potentially less morbid therapies, such as the various forms of ablation, or with systemic treatments. It is apparent that the accuracy of this prediction is essential to allow patients to benefit either by having appropriate surgical therapy or by avoiding potentially unnecessary surgical morbidity.
