BackgroundCalcific aortic stenosis （AS） is an active process sharing similarities with atherosclerosis and chronic inflammation. The pathophysiology of AS is notable for three cardinal components： inflammation, fibrosis and calcification. Monocytes play a role in each of these processes. The role of circulating monocytes in AS is not clear. The aim of the present study was to study an association between cir-culating apoptotic and non apoptotic CD14＋ monocytes and AS *** assessed the number of CD14＋ monocytes and apoptotic monocytes in 54 patients with significant AS （aortic valve area 0.74 ± 0.27 cm2） and compared them to 33 patients with similar risk factors and no valvular disease. The level of CD14＋ monocytes and apoptotic monocytes was assessed by flow *** was no difference in the risk factor profile and known coronary or peripheral vascular diseases between patients with AS and ***-tients with AS exhibited increased numbers of CD14＋ monocytes as compared to controls （9.9% ± 4.9%vs. 7.7% ± 3.9%,P= 0.03）. CD14＋ monocyte number was related to age and the presence and severity of AS. In patients with AS, both CD14＋ monocytes and apoptotic mono-cytes were inversely related to aortic valve *** with significant AS have increased number of circulating CD14＋ monocytes and there is an inverse correlation between monocyte count and aortic valve area. These findings may suggest that inflammation is operative not only in early valve injury phase, but also at later developed stages such as calcification when AS is severe.

The thermoregulation behavior ofLucilia sericata larvae （Diptera： Calliphori- dae）, a necrophagous species that feeds on vertebrate cadavers, was investigated. These larvae require high heat incomes to develop, and can elevate temperatures by forming large aggregates. We hypothesized that L. sericata larvae should continue to feed at temperatures up to 38 ℃, which can be reached inside larval masses. Thermal regulation behavior such as movement between a hot food spot and colder areas was also postulated. The hypotheses were tested by tracking for 1 h the activity of single, starved third instar larvae in a Petri dish containing 1 food spot （FS） that was heated to a constant temperature of 25 ℃, 34 ℃ or 38 ℃ with an ambient temperature of 25 ℃. The influence of previous conspecific activity in the food on larval behavior was also tested. The crops of larvae were dissected to monitor food content in the digestive systems. Based on relative crop measurements, larvae fed at all food temperatures, but temperature strongly affected larval behavior and kinematics. The total time spent by larvae in FS and the duration of each stay decreased at high FS temperature. Previous activity of conspecifics in the food slightly increased the time spent by larvae in FS and also decreased the average distance to FS. Therefore, necrophagous L. sericata larvae likely thermoregulate during normal feeding activities by adjusting to local fluctuations in temperature, particularly inside maggot masses. By maintaining a steady internal body temperature, larvae likely reduce their development time.
