Extreme weather and climate events have received much attention in the last few years, due to the large loss of human life and increasing financial costs often associated with them(Karl and Easterling,1999).Therefore, detection of changes in the frequency of these events has been one of the main themes of current climate research,especially under global warming ***, trends in the frequency of these events are quite diverse,both spatially and temporally (a brief review can be found in Easterling et al.,2000).Among extreme climate events,

目的对比研究链霉素纳米制剂与普通制剂——硫酸链霉素注射液在小鼠体内经肠胃外给药时的抗结核活性。方法雌性BALB/c小鼠尾静脉感染结核分枝杆菌h37Rv 1×107CFU。感染后第2 d开始按照空白对照组、阳性对照组、比较对照组和纳米链霉素SM-NP BSA组、纳米链霉素SM-NP CRM组的剂量和频率分别腹腔注射给药,给药至感染后28 d。在感染的14、28、56 d分别处死每组4只小鼠进行脾、肺活菌计数。结果SM-NP CRM组在整个实验期间的存活率是100%,SM-NP BSA组第28 d和第56 d的存活率分别为83%和75%。治疗14 d时,比较对照组小鼠脾、肺的菌量较阳性对照组大,而SM-BSA与SM-CRM组小鼠脾、肺的活菌数较阳性对照组降低;治疗4周时,各组的活菌数与2周时相比没有明显变化,但SM-NP BSA与SM-NP CRM组的脾、肺活菌数均比比较对照组低,差异有统计学意义。感染8周时,SM-NP BSA、SM-NP CRM组肺的活菌数量仍比阳性对照组小,差异有统计学意义。结论纳米链霉素制剂SM-NP BSA、SM-NP CRM与普通链霉素注射液相比,在给药剂量与给药频率降低时,在小鼠急性结核病感染模型中表现的抗菌活性仍与阳性对照相当,值得进一步研究。

Mars, the intriguing red planet, is one of the planets most similar to the Earth in our solar system. It is widely accepted that Mars could have had a warm and wet climate in its early history supported by numerous lines of evidence, e.g. topography, canyons, outflow channels, presence of phyllosilicates and evaporative salts,sedimentary formation, and many others (e.g.[1]), and thus Mars is believed to once have a potentially habitable environment which could be able to supply fundamental conditions for the evolution of potential lives.

Covalent adaptable networks(CANs),which share the properties of both thermosets and thermoplastics at the same time,are desirable for many *** bulky substituents is a feasible way to design dynamic covalent bonds for constructing CANs,as evidenced by the successful implementation in CANs based on hindered urea bonds(hUBs).however,the dynamicity induced by introducing bulky substituents always come with low bond energy,resulting in low mechanical strength and poor stability of the ***,we designed a novel hindered urethane bond,which is weak in thermodynamic(K_(eq)=1701.23 L/mol at 25℃)and inert in kinetic at low temperature,but stable in thermodynamic(K_(eq)=1.54×10^(4) L/mol at 100℃)and active in kinetic at high temperature(k_(-1)=0.105 h^(-1) at 80℃ and 0.315 h^(-1) at 120℃).As a result,the polyurethane based on it exhibits high mechanical properties(with Youngs’modulus of 1011±29MPa and flexible modulus reached 1833±50MPa)and excellent reversibility(can be reprocessed at 60℃ under 100 kPa in 30 min and completely healed at 40℃ in 10 min).Moreover,unlike to many CANs based on hindered urea bonds,our dynamic polyurethanes are highly stable in humid environment or even water solutions due to the slow hydrolysis *** highperformance dynamic polyurethane polymers are attractive for many applications.
