The motor head of kinesin carries out microtubule binding, ATP hydrolysis, and force generation. Despite a high level of sequence and structural conservation, subtle variations in subdomains of the motor head determine family-specific properties. In particular, both Kinesin-1 (Kin-1) and Kinesin-5 (Kin-5) walk processively to the microtubule plus-end, yet show distinct motility characteristics ...

The thermoinhibition at 35 and 32 degrees C of pregermination ethylene production and germination in lettuce (Lactuca sativa L. cv Mesa 659) seeds was synergistically or additively alleviated by 0.05 millimolar kinetin (KIN) and 10 millimolar 1-aminocyclopropane-1-carboxylic acid (ACC). The synergistic effect of KIN + ACC on ethylene production and germination at 35 degrees C was inhibited by C...

Pitch is an important property of birdsong. Accurate and automatic tracking of pitch for large numbers of recordings would be useful for automatic analysis of birdsong. Currently, pitch trackers such as YIN can work with carefully tuned parameters but the characteristics of birdsong mean those optimal parameters can change quickly even within a single song. This paper presents YIN-bird, a modif...

correlation of genetic VT risk with the plasma levels of the fibrinogen variant suggests that FGG-H2 and -H3 haplotypes modify thrombosis risk by controlling the level of this FGG splice isoform. In response to our manuscript, Cheung and coworkers note that elevated fibrinogen ratios are associated with cardiovascular diseases and acute phase reaction but not with clinical outcome. This is an i...

Significant advances have been made in understanding kin recognition as it pertains to nepotism (preferential treatment of kin) and mate choice (optimization of inbreeding and outbreeding). Yet complementary knowledge about how animals discriminate conspecifics on the basis of genetic relatedness remains unclear for most species. Because of the diversity of their scent sources and highly develo...

Male florets and pistillate flowers of cvs.Chandler and Hartley of Persian walnut were cultured on modified Murashige and Skoog medium (MS) supplemented with 0.05 mg l-1 biotin, 0.5 mg l-1 folic acid, 100 mg l-1 glutamine and different concentrations of Naphthalene acetic acid (NAA) and Kinetin (KIN) and for pistillate flowers culture, these concentrations were 0.25, 0.5, 1 and 2 mg l-1). After...

Cooperation among relatives is often regarded as evidence of kin selection. Yet altruism not requiring shared genes can also evolve among relatives. If characteristics of relatives (such as proximity, familiarity, or trust) make kin preferred social partners, the primary causes of nepotistic biases may reside principally in direct fitness payoffs from cooperation rather than indirect fitness pa...

PURPOSE To identify symptoms/distress among patients with colorectal cancer undergoing chemotherapy, from the viewpoint of the next of kin, and to establish whether there are any barriers to reporting these problems. METHODS Individual face-to-face interviews with fourteen next of kin were conducted. Qualitative content analysis was used to analyse the transcripts. RESULTS Three areas were ...

Arguably, international finance is one of the most exciting areas in economics. The development of international finance is influenced and shaped, at least in part, by the continuing process of globalization and integration. In the last 25 years the profession has witnessed the proliferation of both theoretical models and empirical analyses in international finance. The analysis of both new and...
