一种认为球外天体的一次灾难性冲击造成白垩纪末期恐龙、浮游有孔虫和其它生物种属大量灭绝的假说,目前随着白垩纪-第三纪(K-T)边界粘土中铱元素的富集在世界各地的发现而逐渐被人们所承认。在西班牙卡拉瓦卡K-T边界粘土的底部纹层中,发现了大量细结晶的、属高温透长石构造状态的相当纯的钾长石球粒。这里可以断定,这些球粒是由某种熔体凝固成的,并且可能是由冲击体衍生的。由于在陨石的全分析资料中未见过高钾含量的报道,这就向人们提出了一些问题。某些铁陨石中钾长石斑晶的存在表明,该天体可能是一种金属-硫化物-硅酸盐微星,或者是一种慧星体。

Obj.ctive: This study was designed to evaluate the association between skin autofluorescence (AF), an indicator of advanced glycation end-products (AGEs), and foot ulcers in subj.cts with diabetes. Methods: In this study, 195 Chinese diabetic subj.cts were examined. Their feet were examined regardless of whether an ulcer was present or not. Skin AF was measured with an AGE reader. Demographic characteristics and blood data were recorded. Results: The mean values of skin AF were 2.29±0.47 for subj.cts without foot ulcers, and 2.80±0.69 for those with foot ulcers, a significant difference (Pj.sting for these factors, multivariate logistic regression showed that skin AF was independently associated with foot ulcerations. Conclusions: Skin AF is independently associated with diabetic foot ulcerations. It might be a useful screening method for foot ulceration risk of diabetic patients.

＜正＞A Montium is a coarse-grained reconfigurable architecture designed by the CADTES group of the University of Twente for mobile applications. This paper presents a resource allocation method to allocate variables to storage places and to schedule data movements for the Montium. The resource allocation method exploits locality of reference of the Montium architecture as well as its parallelism.

Retention wires permanently bonded to the anterior teeth are used after orthodontic treatment to prevent the teeth from relapsing to pre-treatment positions. A disadvantage of bonded retainers is biofilm accumulation on the wires, which produces a higher incidence of gingival recession, increased pocket depth and bleeding on probing. This study compares in vivo biofilm formation on single-strand and multi-strand retention wires with different oral health-care regimens. Two-centimetre wires were placed in brackets that were bonded to the buccal side of the first molars and second premolars in the upper arches of 22 volunteers. Volunteers used a selected toothpaste with or without the additional use of a mouthrinse containing essential oils. Brushing was performed manually. Regimens were maintained for 1 week, after which the wires were removed and the oral biofilm was collected to quantify the number of organisms and their viability, determine the microbial composition and visualize the bacteria by electron microscopy. A 6-week washout period was employed between regimens. Biofilm formation was reduced on single-strand wires compared with multi-strand wires; bacteria were observed to adhere between the strands. The use of antibacterial toothpastes marginally reduced the amount of biofilm on both wire types, but significantly reduced the viability of the biofilm organisms. Additional use of the mouthrinse did not result in significant changes in biofilm amount or viability. However, maj.r shifts in biofilm composition were induced by combining a stannous fluoride- or triclosan-containing toothpaste with the mouthrinse. These shifts can be tentatively attributed to small changes in bacterial cell surface hydrophobicity after the adsorption of the toothpaste components, which stimulate bacterial adhesion to the hydrophobic oil, as illustrated for a Streptococcus mutans strain.
