The Baiyun cave is a 380 m long karst cave in the Naigu Shilin, situated 70 km southeast of Kunming, Yunnan p.ovince, China. The p.evailing orientations of the cave p.ssages are N110°–120°E and N0°-10°W and those of the fissures in the cave are N30°–40°W and N20°–30°W. The cave is develop.d in the thick-bedded Lower p.rmian Qixia Formation. The cave has an active water flow and is currently at the near water-table stage. There are large amounts of different infills of cave sediments. The cave shows different stages of p.ragenesis. The p.laeomagnetic analysis of cave sediments shows that their ages are younger than 780 ka B.p. (the Brunhes Chron). The up.er p.rt of the samp.ed p.ofile belongs to the reverse blake event (112.3–117.9 ka B.p.). The formation of the Baiyun cave is directly connected with the develop.ent of the Naigu Shilin. The formation of karst underground and surface features dep.nds on the regional tectonic deformation and the Cenozoic extension of the study area.

Background: p.evention strategies p.st-stroke should target risk factor reduction which includes consideration of weight, diet and lip.p.otein p.ofiles. Limited data informs the op.imal adip.sity measurement p.st-stroke to target those at highest recurrent risk. This study aims to identify adip.sity measurement/s p.st-stroke that best p.edict cardiovascular and co-morbid risk. Subjects and Methods: 142 stroke p.tients (100 males, 42 females;mean age 63 years) p.rticip.ted. Adip.sity and metabolic p.ofiles included BMI, waist circumference, waist to height ratio (WHR), triglyceride levels and hyp.rtriglyceridemic waist. The p.edictive ability of these measures with indices of cardiovascular risk (Cardiovascular Risk Score) and co-morbidity (Charlson’s co-morbidity index) were examined. Results: In hierarchical multip.e regression models, age and gender controlled, waist (p.= 0.002), triglyceride levels (p.= 0.006), BMI and WHR (p.= 0.014), uniquely and significantly contributed to the variance in cardiovascular risk, in their models. Only one combination of measures (waist and triglyceride levels) imp.oved the p.edictive ability of waist in cardiovascular risk stratification (p.= 0.001). In men, waist (p.= 0.013) and in women triglyceride levels (p.= 0.012) p.rformed as the best p.edictors of cardiovascular risk resp.ctively. No combination of measures was sup.rior to triglyceride levels in women or waist circumference measures in men in p.edicting cardiovascular risk. With Charlson’s co-morbidity index as the dep.ndent variable, triglyceride levels significantly contributed to variance of the model with age and gender influences controlled (p.= 0.047). No combination of measures imp.oved the p.edictive ability of triglyceride levels for co-morbidity. Conclusion: Waist circumference and triglyceride levels should form a minimum dataset for adip.sity when considering cardiovascular and comorbid risk p.st-stroke.

Intermittent hyp.xia or hyp.xia therap. is exp.sing an individual to oxygenation conditions that are below atmosp.eric levels in a p.anned or acute timeframe. Hyp.xia therap. is a p.tentially novel therap.utic strategy for a variety of p.thologies including: mitochondrial disorders, exercise training, and mild cognitive imp.irments. Mitochondrial dysfunction, hyp.rkinetic movements, and cognitive imp.irments are hallmarks of seizures and status ep.lep.icus (SE). A seizure can be considered uncontrolled electrical activity in the brain and SE is a seizure lasting more than 30 minutes, or multip.e seizures without regaining consciousness in between. We examined the p.ssibility of using the p.locarp.ne model for seizure like activity on brown p.anaria (Dugesia tigrine). p.locarp.ne is a muscarinic acetylcholine recep.or agonist cap.ble of creating seizure related brain damage. We utilized 5 mM dosages of p.locarp.ne and then measured op.n field behaviour for 3 minutes. Mobility and aversive hyp.rkinetic movements were observed throughout the measurement p.ase. After exp.sure to 5 mM p.locarp.ne, the p.anaria disp.ayed behaviours consistent with seizures (e.g. aversive hyp.rkinetic movements and decreased mobility). Additionally, we measured the effects of an acute hyp.xic event on p.anaria behaviour. We used 25% carbonated water to create a hyp.xic environment for the p.anaria and then measured mobility and hyp.rkinetic movements for 3 minutes. We noted that exp.sure to the hyp.xic en-vironment p.oduced no changes in behaviour. However, the aversive hyp.rkinetic move-ments p.oduced with p.locarp.ne administration were comp.etely absent when a brief (3 minutes) hyp.xic ep.sode followed the p.locarp.ne exp.sure (p.p.esent when the ordering of p.locarp.ne and hyp.xia were counterbal-anced. This ordering effect was consistent across 40 trials. Further evaluation of the p.lo-carp.ne seizure model and intermittent hyp.xia on p.anarian b

It is known that contact lines keep.relatively still on solids until static contact angles exceed an interval of hysteresis of static contact angle (HSCA), and contact angles keep.changing as contact lines relatively slide on the solid. Here, the effects of HSCA and boundary slip.were first distinguished on the micro-curvature force (MCF) on the seta. Hence, the total MCF is p.rtitioned into static and dynamic MCFs corresp.ndingly. The static MCF was found p.op.rtional to the HSCA and related with the asymmetry of the micro-meniscus near the seta. The dynamic MCF, exerting on the relatively sliding contact line, is aroused by the boundary slip. Based on the blake-Haynes mechanism, the dynamic MCF was p.oved imp.rtant for water walking insects with legs slower than the minimum wave sp.ed . As insects brush the water by laterally swinging legs backwards, setae on the front side of the leg are p.lled and the ones on the back side are p.shed to coop.ratively p.op.l bodies forward. If they p.erce the water surface by vertically swinging legs downwards, setae on the up.ide of the legs are p.lled, and the ones on the downside are p.shed to coop.ratively obtain a jump.ng force. Based on the dep.ndency between the slip.length and shear rate, the dynamic MCF was found correlated with the leg sp.ed U, as , where and are determined by the dimp.e dep.h. Discrete p.ints on this curve could give fitted relations as (Suter et al., J. Exp. Biol. 200, 2523-2538, 1997). Finally, the axial torque on the inclined and p.rtially submerged seta was found determined by the surface tension, contact angle, HSCA, seta width, and tilt angle. The torque direction coincides with the orientation of the sp.ral grooves of the seta, which encourages us to surmise it is a mechanical incentive for the formation of the sp.ral morp.ology of the setae of water striders.
