记述了在山西省垣曲县王茅乡郭家村火石坡地点发现的原翼齿兽属一新种──童氏原翼齿兽(Ｄｒｏｐｔｅｒｏｄｏｎ ｔｏｎｇｉ ｓｐ．ｎｏｖ．)。新种比伊尔丁原翼齿兽(Ｐ．ｉｒｄｉｎｅｎｓｉｓ)个体小、下颌联合部靠前、下前臼齿之间有齿隙、ｍ３跟座小。新材料为垣曲盆地可能存在中始新世伊尔丁曼哈期地层提供了证据。     

山西垣曲中始新世中期仓鼠化石

记述了在垣曲盆地郭家村火石坡地点发现的仓鼠类一新种和一个相似种———垣曲古亚鼠 (Palasiomysyuanquensissp .nov.)和垣曲古亚鼠相似种 (Palasiomyscf.P .yuanquensis )。新种以上臼齿前小尖不明显、m1下前边尖与下原尖相连、个体大等特点区别于属型种锥齿古亚鼠 (P .conulus)。古亚鼠化石在火石坡的发现为垣曲盆地可能存在中始新世伊尔丁曼哈期地层提供了又一证据。     

内蒙古巴彦乌兰地区始新世哺乳类及相关地层问题

记述了在内蒙古巴彦乌兰地区发现的４种始新世哺乳动物化石,其中包括１个啮齿类新种──Ｍｅｒｇｅｎｏｍｙｓ ｎｅｉｍｏｎｇｏｌｅｎｓｉｓ ｓｐ．ｎｏｖ。新种与在蒙古共和国发现的属型种Ｍ．ｏｒｉｅｎｔａｌｉｓ的不同在于个体大,下臼齿下外脊和下次小尖相对偏于唇侧。新化石的发现以及对岩石地层的分析表明巴彦乌兰剖面上原认为的伊尔丁曼哈组应包含伊尔丁曼哈及沙拉木伦组两个地层单位。

记裂齿目(哺乳动物纲)一新属——豫裂兽(Yuesthonyx gen.nov.)

古新世晚期裂齿类———丁氏豫裂兽 (新属、新种 ) (Yuesthonyxtingaegen .etsp .nov.)的发现表明了裂齿目在亚洲古新世已相当分化 ,在臼齿形态上有与北美始新世Esthonyx相近的小尖兽 (Meiostylogon)和中间兽 (Interogale) ,也有与北美Megalesthonyx接近的豫裂兽等。根据豫裂兽、Megalesthonyx、和亚洲的Adapidium的上臼齿都具有明显的中附尖等特征可与其他裂齿类相区别 ,新建了豫裂兽科 (YuesthoncidaeFam .nov.)。     

辽宁下白垩统沙海组和阜新组真三尖齿兽类戈壁尖齿兽科新材料（英文）

真三尖齿兽类是了解亚洲白垩纪哺乳动物群演化和转变的重要成员之一。到目前为止沙海组和阜新组(下白垩统上部)已经发现了两种戈壁尖齿兽科以及两种三尖齿兽科的真三尖齿兽类。描述了这些地层产出的真三尖齿兽类的其他材料,包括一新属新种——常氏阜新尖齿兽(Fuxinoconodon changi gen. et sp. nov.)和一枚左下臼齿(鉴定为?Gobiconodontidae gen. et sp. indet.)。这种新的真三尖齿兽类被归入戈壁尖齿兽科(Gobiconodontidae),其特征为:第一下门齿大、门齿和前臼齿的数目变少、臼齿b尖和c尖较大而独立,以及臼齿具有分别属于Gobiconodon第一代或第二代臼齿上独有特征的组合。新材料与同一地区相同层位已经报道的4种真三尖齿兽类表明,虽然科级和属级的多样性似乎已经减少,但亚洲早白垩世晚期仍存在比较多样的真三尖齿兽类。     

Uniform hypothesis of cell behavior--movement, contact inhibition of movement, adhesion, chemotaxis, phagocytosis, pinocytosis, division, contact inhibition of division, fusion.

The cell has been represented as a charged liquid drop. Contrary to the DLVO-theory, the effect of the surface potential upon the value of the interfacial tension of the cell membrane has also been taken into consideration. The cell membrane has visco-elastic properties and its constituents may move against each other. Cell movement is caused by the appearance of a small number of the electrically charged constituents of the cell membrane on the leading edge of the cell. This produces a local decrease in the surface tension and the cell membrane expansion. At the moment of contact between two cells proton transfers occur between the strongly negatively charged microvilli of one cell and the body of the other, analogous to a condenser breakdown. This, through the effect on the surface tension, causes contact inhibition of movement. The distribution of the proton dissociable groups modifies the interaction between the cells (differentiation) and between the cell and the substratum (adhesion). Adsorption of the charged compounds at the surface of the cell membrane, decreasing the surface potential and increasing the surface tension, causes the phenomena of chemotaxis, phagocytosis and pinocytosis. Cell division, considered in the terms of the surface energy, requires an adequate supply of considerable quantities of energy inversely proportional to the surface potential value. In case of a reduction of the distance between the cells, their surface potential and the energetic barrier of the cell division processes increases, and causes contact inhibition of cell division. Due to their high charge, division of neoplastic cells is inhibited much later than division of normal cells, or is completely ininhibited due to geometric conditions. Fusion of the cell membrane in the intra-cellular and intercellular processes is a reverse process in relation to the cell division.     

The Effect of Age and Gender on Al, B, Ba, Ca, Cu, Fe, K, Li, Mg, Mn, Na, P, S, Sr, V, and Zn Contents in Rib Bone of Healthy Humans

The effect of age and gender on major, minor, and trace element contents in the intact rib bone of 80 relatively healthy 15–55-year-old women and men was investigated. Contents or upper limit of contents of 16 chemical elements in the rib bone were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Mean values (M?±?SΕΜ) for the mass fraction of Ba, Ca, Cu, Fe, K, Li, Mg, Na, P, S, Sr, and Zn (milligram per kilogram of dry bone) were as follows: 2.54?±?0.16, 171,400?±?4,050, 1.35?±?0.22, 140?±?11, 1,874?±?71, 0.049?±?0.011, 2,139?±?38, 5,378?±?88, 75,140?±?1,660, 1,881?±?51, 291?±?20, and 92.8?±?1.5, respectively. The upper limits of contents of Al, B, Mn, and V were <7.20, <0.65, <0.36, and <0.03, respectively. Statistically significant tendency for the Ca, Mg, and P content to decrease with age was found in the human rib bone, regardless of gender. The mass fraction of Fe in the male rib bone increases with age. It was shown that higher Ca, Mg, Na, P, and Sr mass fractions as well as lower Fe content were typical of female ribs as compared to those in male ribs.     

Distribution of N,P, K,Ca, Mg,S, Zn,Fe, Mn and Cu in groundnut

Summary Concentration of N, P, K, Ca, Mg and S in summer groundnut crop was higher than in kharif while Zn, Fe, Mn and Cu contents were higher in summer crop. Kernel's N, P and Zn; Leaflet's Ca and Mn; Stem's K and Fe; Root's S and Cu and Petiole's Mg contents were highest. Shell's N, P, K, Mg, S, Zn and Cu; Kernel's Ca, Fe and Mn contents were the least. N, P, K, S, Zn and Cu concentrations decreased linearly as the crop grew. Ca, Mg, Fe and Mn concentrations did not display any distinct pattern. Ca concentration was positively correlated with pod yield in both the seasons.     

Synthesis,tautomerism, and antimicrobial,anti-HCV,anti-SSPE,antioxidant, and antitumor activities of arylazobenzosuberones

2-Dimethylaminomethylene-1-benzosuberone 1 was coupled with diazotized aniline derivatives to afford a series of the hitherto unreported 2-arylazo-1-benzosuberones 3a–i. The tautomeric structure and the effect of substituents on the tautomeric form (s) of the products 3a–i were discussed. Similar coupling of the enaminone 1 with diazonium salts of heterocyclic amines gave the respective fused azolotriazino-benzosuberones. Some of the newly synthesized compounds showed potent antimicrobial, anti-HCV, antioxidant, antitumor (as topoisomerase I inhibitors), and antimicrobial activities.     

The effect of malathion,diazinon, and various concentrations of zinc,copper, nickel,lead, iron,and mercury on fish

Acute and chronic toxicity tests for malathion, diazinon, copper (Cu), mercury (Hg), lead (Pb), zinc (Zn), nickel (Ni), and iron (Fe) were conducted. Mortalities ofBarilius vagra andCyprinus carpio (common carp) were variable but LC50-96 hr were similar for pesticides. AdultB. vagra seem to be more sensitive to malathion than juvenile carp. Both juvenile carp and adultB. vagra were extremely sensitive to diazinon. Long-term exposure to pesticides modified morphology and behavior. The LC50-96 values for Cu, Hg, and Pb were 0.3, 0.16, and 0.44, respectively, for smaller fish and 1.0, 0.77, and 1.33, respectively, for larger fish. Replicate LC50 values for Zn, Ni, and Fe were somewhat variable, and for these metals, the size of the fish seemed to affect response because LC50 values increased as fish size increased. Cooper, Pb, Zn, and Fe residues following exposure to sublethal concentrations of these metals for 15 d were significantly greater in whole juvenile common carp than in controls.
