Carbon nitride thin films have been deposited by radio frequency sputtering at different substrate temperatures. The electronic structure and optical properties of the films have been systematically studied for the different substrate temperatures. The maximum n concentration in the films arrived at 41 at.%. The binding energy of core levels C 1s and n 1s produces a large shift in the range of 3.5-0.3eV depending on substrate temperature Ts. The band gap is at about 0.61-1.22eV. n atom concentration and shift of core level as well as electron band gap decrease with increasing Ts, which illustrates that raising Ts is not a good way to form carbon nitride films. Ultraviolet-visible near infrared spectra show that the films have a good transparency in near infrared region, but there is a sharp absorption peak around 2720 nm. The peak disappears when Ts is higher than 400℃.

Tungsten oxide (WO) attracts attention of many researchers mainly for its interesting physical and also chemical properties. It is known as a good photochromic,electrochromic, thermochromic and gas sensor material. Recently, a special attention received this material when based on a mesoporous structure. The formation of such a structure requires removing of organic component out of the base matrix that is in this case prepared from sol-gel precursor

AIM: To evaluate the neuroprotective effect of a dietary supplement(ClearVision EX~?;CV) against glutamateinduced excitotoxicity in ***: We evaluated the protective effects CV on glutamate-induced cell toxicity of an immortalized mouse hippocampal cell line(HT-22) in vitro and n-methyl-Daspartate(nMDA) induced retinal injury in vivo. Once-daily oral administration of CV or vehicle(5% Arabic gum) was started the day before the nMDA injection and continued until the end of the study. Electroretinograms(ERGs) were recorded to evaluate the retinal function at 2 d after nMDA injection. Furthermore, a histological evaluation, Western blot analysis, and immunohistochemistry were performed for assessing the signal transduction pathway. RESULTS: HT-22 cell death was induced by the addition of glutamate and co-incubation with CV protected against it. Oral administration of CV inhibited the decrease in scotopic threshold response amplitudes induced by the intravitreal injection of nMDA and those of the thickness of the inner retinal layer in the histological evaluation. The increased phosphorylated levels of extracellular signalregulated kinase(ERK) but not cAMP response element binding protein(CREB) or Akt were observed 1 h after nMDA injection in both the vehicle-and CV-treated rats;however, p ERK activation was no more upregulated at 3 h after nMDA injection. pERK upregulation was observed in Müller ***: CV shows a protective effect against both glutamate-induced HT-22 cell death and nMDAinduced retinal damage. pERK upregulation in the Müller cells plays a key role in the protective effect of CV against glutamate-induced retinal toxicity.

BACKGROUnD: Marked leukocytosis is occasionally observed in patients with a ma lignant nonhematopoietic tumor. Granulocyte colony-stimulating factor (G-CSF)m ay be responsible for this phenomenon. We report a case of G-CSF-producing squ amous cell carcinoma of the cervix that showed marked leukocytosis. CASE: A 71- year-old Japanese woman was admitted for further investigation for leukocytosis . Her white blood cell (WBC) count had been gradually increasing over a period o f 10 months. Laboratory data on admission revealed marked leukocytosis, with a W BC count of 30,400/μL, which consisted primarily of mature granulocytes (93%). Her serum G-CSF level was significantly elevated. However, there was no eviden ce of infection or hematopoietic disorders. Further examinations showed stage II Ib cervical cancer. The pathological diagnosis was squamous cell carcinoma of th e nonkeratinizing type. Immunohistochemical staining of the biopsied specimens c onfirmed the production of G-CSF protein by the tumor cells. The patient was su ccessfully treated by radiation therapy. Her WBC count returned to a normal leve l (3,700/μL). Her serum G-CSF level also decreased. The patient is alive witho ut evidence of recurrence at 8 months after the treatment. COnCLUSIOn: It is sug gested that the leukocytosis manifested in this patient was due to G-CSF produc ed by the tumor. It was possible to use the WBC count and serum G-CSF levels as additional tumor markers.

Organisms are said to be in developmental rate isomorphy when the pro- portions of developmental stage durations are unaffected by temperature. Comprehensive stage-specific developmental data were generated on the cabbage beetle, Colaphellus bowringi Baly （Coleoptera： Chrysomelidae）, at eight temperatures ranging from 16℃ to 30℃ （in 2℃ increments） and five analytical methods were used to test the rate isomor- phy hypothesis, including：（i） direct comparison of lower developmental thresholds with standard errors based on the traditional linear equation describing developmental rate as the linear function of temperature; （ii） analysis of covariance to compare the lower devel- opmental thresholds of different stages based on the Ikemoto-takai linear equation; （iii） testing the significance of the slope item in the regression line of arcsin（√p） versus tem- perature, where p is the ratio of the developmental duration of a particular developmental stage to the entire pre-imaginal developmental duration for one insect or mite species; （iv） analysis of variance to test for significant differences between the ratios of developmental stage durations to that ofpre-imaginal development; and （v） checking whether there is an element less than a given level of significance in the p-value matrix of rotating regres- sion line. The results revealed no significant difference among the lower developmental thresholds or among the aforementioned ratios, and thus convincingly confirmed the rate isomorphy hypothesis.

初步报道了缺缺洞发现的猕猴化石。新材料为一具雄性老年猕猴个体的骨架,保存了几乎完整的下颌、全部7节颈椎、9节胸椎、两侧前肢肢骨、右侧后肢部分肢骨以及绝大部分的腕(跗)骨、掌(蹠)骨和指(趾)骨。这是目前为止中国发现的最为完整的猕猴骨架化石。鉴于化石对比材料的缺乏,仅对下颌及牙齿形态进行了描述,并将之与中国已知各化石种进行了对比。由于中国猕猴属各化石种之间的系统关系尚不明确,暂将这批材料作未定种处理,更加深入的研究将另文发表。

以前的论文,根据田间调查①②和实验室模式试验②③,都强调过淹育水稻土还原层中非共生固氮（n2）的重要性。在这些调查研究中已发现:施肥试验小区内的非共生固氮（n2）活度高于没施肥的试验小区内的非共生固氮活度。现在,更进一步确定:水稻土中绝大部分土壤有机质是以有机碎屑形态存在④;有机碎屑的数量,在施肥试验小区高于没施肥的试验小区⑤;并且在有机碎屑上及其附近,土壤微生物活度是很高的。有机碎屑可能就是非共生固氮（n2）的微场。根据这种假定设置的这种试验将在本文中叙述。

植食性昆虫的味觉和嗅觉在它们识别寄主植物的过程中是至关重要的。对于家蚕以及其野生种中国野桑蚕,其成虫的嗅觉器官(触角)的形态和应答反应已有深入的调查研究。然而对于成虫的味觉器官的表征以及驯化对味觉器官的影响问题还有待解决。东京大学的takaiH等人发现,在家蚕和野桑蚕中都有两种类型的味觉感受器[浓密型(T)和纤细型(S)],位于成虫足的第五跗分节。不管是家蚕还是野桑蚕,雌性的T型感受器都是雄性的3.6～3.9倍。因此推测,相对于雄性,T型感受器对于雌性更加重要。而且,在电生理实验中,雌性野桑蚕的T型感受器味觉细胞对于桑叶提取物的反应十分强烈,而雌性家蚕(n4)的T型感受器味觉细胞对于桑叶提取物几乎没有反应。这些结果可以表明雌性野桑蚕的T型感受器可能与产卵地识别密切相关。研究人员还发现3个家蚕品系(n4,p50T,Kinshu×Showa)第五跗分节的感受器密度都远远低于野桑蚕。这些结果表明,驯化影响了家蚕足的味觉系统。
