TL;DR: The incidence of injuries and illnesses varied substantially among sports and the risk of an athlete being injured was the highest in taekwondo, football, BMX, handball, mountain bike, athletics, weightlifting, hockey and badminton, and the lowest in archery, canoe slalom and sprint, track cycling, rowing, shooting and equestrian.
Abstract: Background The Olympic Movement Medical Code encourages all stakeholders to ensure that sport is practised without danger to the health of the athletes. Systematic surveillance of injuries and illnesses is the foundation for developing preventive measures in sport. Aim To analyse the injuries and illnesses that occurred during the Games of the XXX Olympiad, held in London in 2012. Methods We recorded the daily occurrence (or nonoccurrence) of injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC) medical teams and (2) in the polyclinic and medical venues by the London Organising Committee of the Olympic and Paralympic Games’ (LOCOG) medical staff. Results In total, 10 568 athletes (4676 women and 5892 men) from 204 NOCs participated in the study. NOC and LOCOG medical staff reported 1361 injuries and 758 illnesses, equalling incidences of 128.8 injuries and 71.7 illnesses per 1000 athletes. Altogether, 11% and 7% of the athletes incurred at least one injury or illness, respectively. The risk of an athlete being injured was the highest in taekwondo, football, BMX, handball, mountain bike, athletics, weightlifting, hockey and badminton, and the lowest in archery, canoe slalom and sprint, track cycling, rowing, shooting and equestrian. 35% of the injuries were expected to prevent the athlete from participating during competition or training. Women suffered 60% more illnesses than men (86.0 vs 53.3 illnesses per 1000 athletes). The rate of illness was the highest in athletics, beach volleyball, football, sailing, synchronised swimming and taekwondo. A total of 310 illnesses (41%) affected the respiratory system and the most common cause of illness was infection (n=347, 46%). Conclusions At least 11% of the athletes incurred an injury during the games and 7% of the athletes’ an illness. The incidence of injuries and illnesses varied substantially among sports. Future initiatives should include the development of preventive measures tailored for each specific sport and the continued focus among sport bodies to institute and further develop scientific injury and illness surveillance systems.

TL;DR: Plasmid reporter vectors have been constructed which respond to activation of LuxR and its homologues LasR and RhlR by N-acyl homoserine lactones by AHLs, allowing a comprehensive evaluation of quorum sensing signals from a test organism.
Abstract: Plasmid reporter vectors have been constructed which respond to activation of LuxR and its homologues LasR and RhlR (VsmR) by N-acyl homoserine lactones (AHLs). The expression of luxCDABE from transcriptional fusions to PluxI, PlasI and PrhlI respectively, occurs in the presence of activating AHLs. A profile of structure/activity relationships is seen where the natural ligand is most potent. The characterisation of individual LuxR homologue/AHL combinations allows a comprehensive evaluation of quorum sensing signals from a test organism.

TL;DR: A review of the existing literature on venture capital and private equity can be found in this article, where the authors emphasise the importance of examining venture capital in the light of recent developments in corporate finance and its distinctiveness from other forms of finance.
Abstract: This paper reviews the existing literature on venture capital and private equity. The paper emphasises the importance of examining venture capital in the light of recent developments in corporate finance and its distinctiveness from other forms of finance. In order to understand current developments, the paper adopts a framework which combines industry/market and firm levels of analysis. Existing literature is reviewed using this framework. Industry level issues relate to rivalry between firms, the power of suppliers and customers, and the threats from new entrants and substitutes. Firm level issues concern deal generation, initial and second screening, valuation and due diligence, deal approval and structuring, post-contractual monitoring, investment realisation, and entrepreneurs’ exit and recontracting with venture capitalists. This is followed by a review of the evidence on the performance of venture capital firms. The paper suggests potentially fruitful areas for further research including the extension of analysis to cover all stages of venture capital investment, examination of the inter-linkages between industry and firm level issues and between stages in the venture capital process, as well as further analysis of deal structuring issues and investment realisation and recontracting.

TL;DR: The data indicate that IRPs constitute part of the execution machinery of mammalian apoptosis induced by deregulated oncogenes, DNA damage, or Bak but that they act after the point at which cells become committed to apoptosis or can be rescued by survival factors.
Abstract: There is increasing evidence for a central role in mammalian apoptosis of the interleukin-1 beta-converting enzyme (ICE) family of cysteine proteases, homologues of the product of the nematode "death" gene, ced-3. Ced-3 is thought to act as an executor rather than a regulator of programmed cell death in the nematode. However, it is not known whether mammalian ICE-related proteases (IRPs) are involved in the execution or the regulation of mammalian apoptosis. Moreover, an absolute requirement for one or more IRPs for mammalian apoptosis has yet to be established. We have used two cell-permeable inhibitors of IRPs, Z-Val-Ala-Asp.fluoromethylketone (ZVAD.fmk) and t-butoxy carbonyl-Asp.fluoromethylketone (BD.fmk), to demonstrate a critical role for IRPs in mammalian apoptosis induced by several disparate mechanisms (deregulated oncogene expression, ectopic expression of the Bcl-2 relative Bak, and DNA damage-induced cell death). In all instances, ZVAD.fmk and BD.fmk treatment inhibits characteristic biochemical and morphological events associated with apoptosis, including cleavage of nuclear lamins and poly-(ADP-ribose) polymerase, chromatin condensation and nucleosome laddering, and external display of phosphatidylserine. However, neither ZVAD.fmk nor BD.fmk inhibits the onset of apoptosis, as characterized by the onset of surface blebbing; rather, both act to delay completion of the program once initiated. In complete contrast, IGF-I and Bcl-2 delay the onset of apoptosis but have no effect on the kinetics of the program once initiated. Our data indicate that IRPs constitute part of the execution machinery of mammalian apoptosis induced by deregulated oncogenes, DNA damage, or Bak but that they act after the point at which cells become committed to apoptosis or can be rescued by survival factors. Moreover, all such blocked cells have lost proliferative potential and all eventually die by a process involving cytoplasmic blebbing.
