选取宛氏拟青霉(AS 3.776)和黄曲霉(CICC 2476)作为试验菌株,于121℃高温灭菌前、后添加一定浓度梯度的亚麻籽环肽混合物(flaxseed cyclolinopeptides,FCLPs)到马铃薯葡萄糖琼脂培养基中。FCLPs对宛氏拟青霉孢子形成的半数抑制浓度IC50分别为0.53 mg/m L(高温灭菌)和0.34 mg/m L(未经高温灭菌);对黄曲霉孢子形成的IC50值分别为0.31 mg/m L(高温灭菌)和0.24 mg/m L(未经高温灭菌)。高温灭菌处理后,FCLPs保持了相当的抑菌活性,对宛氏拟青霉的抑制活性最低残留76.8%(菌落生长)和76.7%(孢子形成);对于黄曲霉的抑制活性,最低残留分别为61.6%(菌落生长)和41.7%(孢子形成)。FCLPs对孢子萌发率的平均抑制率为17.8%(宛氏拟青霉)和7.8%(黄曲霉)。采用高效液相色谱法分析霉菌培养后从培养基中提取的FCLPs,发现高温灭菌会降低环肽的含量,这可能是导致环肽抗菌活性下降的原因之一,但环肽中4种主要环肽的比例没有发生明显变化,且没有发现环肽霉菌代谢物产生。综上所述,FCLPs对霉菌具有一定抑制活性,对高温处理较为稳定,能耐食品的热加工,相比现有抗菌肽具有独特优势。

Investigations on malaria outbreaks and role of sibling species complex of principal rural malaria vector Anopheles culicifacies were carried out in villages in north Karnataka, India from 1997 through 2014. Information regarding densities, resting and breeding habitats of malaria vectors prevalent in the area was also generated so as to formulate an appropriate vector control strategy. The Slide Positivity Rate (SPR), Slide Falciparum Rate (SFR) and Pf proportion was 43.1%, 35.9% and 83.3%, respectively. Three sibling species A, B, and C of An. culicifacies were found sympatric with cumulative percent composition of 63.7, 28.2 and 8.1, respectively. Per man hour and per structure densities of An. culicifacies, An. culicifacies and An. culicifacies varied from 0 to 27.5 and 0 to 56.0, 0 to 0.5 and 0 to 7.0 and, 0 to 2.5 and 0 to 7.5, respectively. The proportion of semi-gravid and gravid females was more as compared to fully fed and unfed females which indicated that most of the females rested indoor. Streams/river, wells, seepages and irrigation tanks are the major habitats supporting breeding of An. culicifacies. Integrated vector managements by indoor residual spraying of effective insecticide as per national guidelines along with biological control methods especially use of larvivorous fish Gambusia affinis and Poecilia reticulate are suggested to control malaria in the area.

A series of reticulated Arabidopsis thaliana mutants were previously described. All mutants show a reticulate leaf pattern, namely green veins on a pale leaf lamina. They have an aberrant mesophyll structure but an intact layer of bundle sheath cells around the veins. Here, we unravel the function of the previously described reticulated EMS-mutant dovl （differential development of vascular associated cells 1）. By positional cloning, we identified the mutated gene, which encodes glutamine phosphoribosyl pyrophosphate aminotransferase 2 （ATase2）, an enzyme catalyzing the first step of purine nucleotide biosynthesis, dovl is allelic to the previously characterized cial-2 mutant that was isolated in a screen for mutants with impaired chloroplast protein import. We show that purine-derived total cytokinins are lowered in clovl and crosses with phytohormone reporter lines revealed differential reporter activity patterns in dovl. Metabolite profiling unraveled that amino acids that are involved in purine biosynthesis are increased in dovl. This study identified the mo- lecular basis of an established mutant line, which has the potential for further investigation of the interaction between metabolism and leaf development.

本试验是单纯用肌肉注射激素对奶牛卵巢囊肿进行治疗的,其中给77头黄体囊肿病牛注射前列腺素F_(2a)类似物前列氯酚(500μg),给116头卵泡囊肿病牛注射促性腺激素(500μg),或促性腺激素释放激素(GnRH)或其类似物busereIin(20μg)无论发情与否,治愈标准为:在治疗后10天(前列氯酚)或15天(GnRH)内,囊肿消失,黄体形成。两种疗法的痊愈率和痊愈平均时间分别为65％、52.6％和4.9、19天。用GnRH治疗后15天,有20头牛的卵泡发生黄体化,接着再用前列氯酚治疗,结果有15头牛痊愈,其痊愈时间平均为20.4天;然而,有10头牛治疗后卵泡囊肿仍不消失,对这些牛继续用GnRH治疗31天后,结果只有1头痊愈。另外27头囊肿黄体化牛,在用GnRH处理后7天,再用前列氯酚,结果痊时间缩短(11.5天),但痊愈率较低(48％),囊肿复发率增高(33％)。25头卵巢囊肿病牛用孕酮子宫内释放装置(PRID)治疗(其中有些病牛以前曾治疗过)。在平均15天内,有68％病牛痊愈。不同方法治疗后给牛输精1—3次,结果妊娠率相似(77—94％)。我们发现,用GnRH治疗卵泡囊肿,用前列氯酚治疗黄体囊肿和GaRH处理后15天内引起的囊肿黄体化,是获得痊愈的最好方法。试验表明,对卵泡囊肿用GnRH处理后第7天而不是15天时,前列氯酚的治愈率较低。这是由于下丘脑和垂体腺受孕酮影响的时间太短。

A series of compounds Ba5-xSrxGdTi3V7O30 (x = 0 - 5), belonging to tungsten bronze family were prepared by a high-temperature solid-state reaction route. Using X-Ray diffraction technique and Scanning Electron Micrograph, the formation and surface morphology of the compounds were studied. The X-Ray diffraction study informs the formation of single-phase orthorhombic structures. The substitution of Sr ion with increasing concentration in the compounds as per formula resulted in a variation of the electrical properties. Study of electrical properties using impedance analyzer exhibits: 1) the presence of negative temperature coefficients of resistance (NTCR) behavior;2) presence of temperature dependent electrical relaxation phenomena;3) evidences of single electrical relaxation attributed to the presence of bulk contribution to the electrical properties for pure Ba5GdTi3V7O30 compound;4) an enhancement in the barrier to the mobility of charge carriers on Sr-substitution. The effects of Sr on changes in the electrical conductivity as a function of temperature at different frequency are described based on impedance spectrum analysis.

We report on the current-voltage (I-V) and capacitance-voltage (C-V) characteristics of the Pd/Ti/n-InP Schottky barrier diodes (SBDs) in the temperature range 160-400 K in steps of 40 K. The barrier heights and ideality factors of Schottky contact are found in the range 0.35 eV (I-V), 0.73 eV (C-V) at 160 K and 0.63 eV (I-V), 0.61 eV (C-V) at 400 K, respectively. It is observed that the zero-bias barrier height decreases and ideality factor n increase with a decrease in temperature, this behaviour is attributed to barrier inhomogeneities by assuming Gaussian distribution at the interface. The calculated value of series resistance (Rs) from the forward I-V characteristics is decreased with an increase in temperature. The homogeneous barrier height value of approximately 0.71 eV for the Pd/Ti Schottky diode has been obtained from the linear relationship between the temperature-dependent experimentally effective barrier heights and ideality factors. The zero-bias barrier height ( ) versus 1/2kT plot has been drawn to obtain evidence of a Gaussian distribution of the barrier heights and values of = 0.80 eV and = 114 mV for the mean barrier height and standard deviation have been obtained from the plot, respectively. The modified Richardson ln(I0/T2)- ( ) versus 1000/T plot has a good linearity over the investigated temperature range and gives the mean barrier height ( ) and Richardson constant (A*) values as 0.796 eV and 6.16 Acm-2K-2 respectively. The discrepancy between Schottky barrier heights obtained from I-V and C-V measurements is also interpreted.
