NWL代数的性质及其滤子与理想

NML代数是MV代数和NM(R0)代数的共同基础,因而其系统居于承上启下的地位,在NML代数中引入滤子(理想)这个工具以后,可以证明许多代数系统具有可嵌入性,从而为这些形式系统具有完备性作了准备.讨论了NML代数的性质,并且在NML代数上引入MP-滤子与MP-理想以及布尔MP-滤子和布尔MP-理想的概念,并利用布尔MP-滤子建立了NML代数的结构:若F是布尔滤子,则M/～F是布尔代数,即NML代数的商代数是布尔代数.

Differential scanning calorimetric study of muscle and its proteins: Myosin and its subfragments

The thermal denaturation of rabbit skeletal muscle myosin and its subfragments was investigated by differential scanning calorimetry. The thermal denaturation of myosin was shown to occur via three (at least) partly independent cooperative endothermic processes. The temperatures at which these processes occurred (312, 317 and 323 K at pH 6.0 and I=1.0) were shown to vary with pH (5.5–8.0) and I (0.05–1.0). The apparent enthalpy of denaturation of myosin was also shown to be dependent on pH and I. By comparing thermograms of myosin with those of the isolated myosin subfragments, the three major processes associated with the thermal denaturation of rabbit myosin could be tentatively assigned to different regions of the myosin molecule, namely, the helical tail, the ‘hinge-region’ and the globular heads. The ‘hinge-region’ thermal denaturation was shown to be reversible at pH 6.0 and I=1.0. Investigations of the effects of ortho-, pyro-, and tripolyphosphate on the thermal denaturation of myosin showed that added pyrophosphate destabilised the myosin molecule by about 9 K compared to the effects of ortho and tripolyphosphate, even though the latter was probably hydrolysed to ortho and diphosphate.

Cellulite and its treatment

The presence of cellulite is an aesthetically unacceptable cosmetic problem for most post-adolescent women. It is largely observed in the gluteal-fermoral regions with its 'orange-peel' or 'cottage cheese' appearance. It is not specific to overweight women although increased adipogenicity will exacerbate the condition. It is a complex problem involving the microcirculatory system and lymphatics, the extracellular matrix and the presence of excess subcutaneous fat that bulges into the dermis. It has been described as a normal condition that maximizes subcutaneous fat retention to ensure adequate caloric availability for pregnancy and lactation. Differences in the fibrous septae architecture that compartmentalize the adipose tissue have recently been reported in women with cellulite compared with men. Weight loss has been reported to improve the cellulite severity by surface topography measures although in obese subject's skin dimpling does not seem to change appreciably. However, histological analysis suggests that fat globules retract out of the dermis with weight loss. Cellulite has been treated with massage which decreases tissue oedema but it is also likely to have its effects at the cellular level by stimulating fibroblast (and keratinocyte) activity while decreasing adipocyte activity. In addition to massage, effective topical creams with a variety of agents were used to ameliorate the condition. Nevertheless, only a few studies are reported in the scientific literature. Xanthines, botanicals, fragrances and ligands for the retinoid and peroxisomal proliferator-activated receptors appear to be giving some benefit. Reducing adipogenesis and increasing thermogenesis appear to be primary routes and also improving the microcirculation and collagen synthesis. Many agents are being investigated for weight management in the supplement industry [hydroxycitrate, epigallocatechin gallate, conjugated linoleic acid (CLA), etc.] and some of these agents seem to be beneficial for the treatment of cellulite. In fact, CLA was proven to ameliorate the signs of cellulite. One product, Cellasene, containing a variety of botanicals and polyunsaturated fatty acids also appears to provide some relief from these symptoms. Although more work is needed, clearly these treatments do improve the appearance of skin in subjects with cellulite. It is quite possible, however, that synergies between both oral and topical routes may be the best intervention to ameliorate the signs and symptoms of cellulite.
