Gelatin-coated,3d sponge-like scaffolds based on 45S5 bioactive glass were produced using the foam replication *** strength tests of gelatin-coated samples compared to uncoated scaffolds showed significant strengthening and toughening effects of the gelatin coating with compressive strength values in the range of cortical ***,the crosslinked gelatin network(using either caffeic acid or N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride(EdC)/N-hxdroxysuccinimide(NHS)as crosslinking agent)was shown to be a suitable candidate for the sustained release of the bioactive molecule *** bioactivity of the produced scaffolds,characterization by FTIR and SEM indicated the formation of hydroxyapatite(HA)in all samples after immersion in simulated body fluid(SBF)for 14 days,highlighting the favorable combination of mechanical robustness,bioactivity and drug delivery capability of this new type of scaffolds.

Given a finite simple graph G, a set d ⊆V(G) is called a dominating set if for all v ∈ V(G) , either v ∈ d or v is adjacent to some vertex in d. A dominating set d is independent if none of the vertices in d are adjacent, and d is perfect if each vertex not in d is adjacent to precisely one vertex in d. If a dominating set is both independent and perfect, then it is called an efficient dominating set. For a graph G, a set d is called a unique efficient dominating set of G if it is the only efficient dominating set of G. In this paper, the authors propose the definition of unique efficient dominating set, explore the properties of graphs with unique efficient dominating sets, and completely characterize several families of graphs which have unique efficient dominating sets.

本文用多维谱分析的方法,研究了1984年夏季张掖地区辐射参数的中短期和超短期振荡特征。1984年夏季,张掖地区辐射等参数存在着3—5天的中短期振荡及30分钟、50分钟和80分钟的超短期振荡。准3天振荡主要存在于热力边界层,振荡是由西向东传播的,影响高度大致力400 hPa。超短期振荡强度有着明显的日际变化,其变化周期也大致力3—5天。在大气中各种时间尺度的振荡之间存在着某种联系。准3天振荡可能是青藏高原地面热力扰动影响的一种反映;准30分钟的超短期振荡强度与天气系统的关系不明显,而与热力状况及主要云状却有一定的关系。

dear Editor,Kras and p53 mutation are among the most common gene mutations in lung cancer,which has both the highest incidence and mortality rate among cancers.1 Kras/p53 mutation also causes mitochondrial dysfunction,which has been implicated to promote the inflammation-to-cancer transition.2 We established a lung adenocarcinoma model by using conditional alleles of KrasLSLG12d/p53flox/flox in mice3 to evaluate the effect of Baicalein(5,6,7-trihydroxyflavone),a principal component of Scutellaria baicalensis in traditional Chinese medicine,4 on the initiation and progression of lung ***-mediated expression of KrasG12d and deletion of p53 caused obvious tumor lesions in the lung,which were strongly inhibited by the administration of Baicalein(Fig.1a,b and Supplementary Fig.1a,b),indicating that Baicalein is highly potent in inhibiting the progression of primary lung cancer.

世界核心医学期刊文摘（神经病学分册） 2005年第11期1卷 28-29页

Objective. -To describe the efficacy and tolerability of rapid intravenous valproic acid (VPA) infusions in children with severe migraine headache. Background. -Intravenous VPA is an emerging treatment option for acute migraine headache. Adult data suggests both efficacy and tolerability of rapid VPA infusions as abortive therapy, but little data exist in children. Methods. -We conducted a retrospective chart review of all children who received intravenous VPA at The Children’s Hospital Headache Clinic during an 18-month study period. Baseline intensity of headache pain, time at which maximum relief was attained, pain reduction following therapy, dose and duration of VPA infusion(s), patient’s pulse, blood pressure, respiratory rate, and pulse oximetry were collected. Adverse events were also recorded. Results. -Thirty-one children (age =15 ±2 years; 81%female) requiring 58 clinic visits and 71 VPA infusions were included. Most visits (n=45; 78%) resulted in only one dose of VPA (976 ±85 mg infused over 12 ±4 minutes) for desired pain relief. Percent pain reduction in those children was 39.8%, with time to maximum relief of 63 ±.31 minutes. Some children required a second dose of 500 mg (n=13 visits; 22%), that was infused over 14 ±6 minutes and produced a 57%reduction in pain intensity from baseline. VPA infusions were well tolerated. Adverse events described included cold sensation (1), dizziness (3), nausea (1), possible absence seizure (1), paraesthesia (2), and tachycardia (2). Conclusions. -Rapid infusion of intravenous VPA is generally well tolerated and may play a role in the management of children with acute migraine headache. Prospective, controlled trials to further investigate this treatment in children are warranted.

We present a diode-pumped, electro-optically Q-switched Tm:YAG laser with a cryogenically cooled laser crystal at120 K. Output pulses of up to 2.55 mJ and 650 ns duration were demonstrated in an actively Q-switched configuration with a repetition rate of 1 Hz. By using cavity dumping the pulse duration was shortened to 18 ns with only a slightly lower output energy of 2.22 mJ. Furthermore, using a simplified rate equation model, we discuss design constraints on the pump fluence in a pulse pump approach for Tm:YAG to maximize the energy storage capability at a given pump power.
