＜正＞The development of the traditional cancer diagnostic markers has been largely disappointing and is clearly not able to meet the needs in cancer patient care. One reason is that highly heterogeneous specimens from cancer patients require multiple markers to produce a clinically useful assay. DNA microarray technology is widely used to classify tu-

Structural basis for the selectivity of Gleevec

中国化学会第九届全国量子化学学术会议

作者： Yi Liu Genomics Institute of the Novartis Research Foundation, 10675 John Jay Hopkins Drive, San Diego, ca 92121, USA

＜正＞The success of anticancer drug Gleevec has stimulated a new paradigm for targeted cancer therapeutics and protein kinases have become one of the most important groups of anticancer drug targets. Given the fact that over 500 protein kinases are encoded by human genome and they all share a highly conserved kinase domain, a challenge in kinase drug discovery is to identify new and selective kinase inhibitors. Gleevec is a highly selective kinase inhibitor. It inhibits Bcr-Ab1 and only a few of other protein kinases such as PDGFR and c-Kit. Therefore understanding the

Journal of High Energy Physics, Gravitation and Cosmology 2024年第3期10卷 1095-1137页

作者： Rafael cañete Mesa Independent Researcher Seville Spain

In this paper we develop and study, as the second part of one more general development, the energy transmutation equation for the material singularity, previously obtained through the symmetrisation of a wave packet, that is, we develop the correlation between the terms of this equation, which accounts for the formation of matter from a previous vibrational state, and the different possible energy species. These energetic species are ascribed, in a simplified form, to the equation E¯ω=E¯k+E¯f, which allows us, through its associated phase factor, to gain an insight into the wave character of the kinetic energy and thus to attain the basis of the matter-wave, and all sorts of related phenomenologies, including that concerning quantum entanglement. The formation of the matter was previously identified as an energetic process, analogous to the kinetic one, in which finally the inertial mass is consolidated as a mass in a different phase, now, in addition, the mass of the material singularity is identified as a volumetric density of waves of toroidal geometry created in the process of singularisation or energy transfer between species, which makes it possible to establish the real relation or correspondence between the corpuscular and photonic energy equation (E=mc2=hν), i.e. to explain through m the intimate sense of the first equivalence, which explains what νis in the second one.

Open Journal of Ecology 2024年第2期14卷 101-113页

This study was conducted to provide a preliminary assessment of the sea cucumber fishery in Aurora, Philippines. This was conducted from February to June 2013. All sea cucumber gatherers and traders, obtained through snowball sampling, in each identified sea cucumber fishery area in six coastal municipalities (Baler, Dipaculao, Dinalungan, casiguran, Dilasag and Dingalan) were interviewed using a structured interview schedule and focused group discussions (FGD). Results revealed that gathering sea cucumbers were accomplished by handpicking, skin diving or compressor diving. A total of 15 commercial species were regularly gathered. Out of this, three species are of very high economic value (≥Php 4000/kg) (Holothuria nobilis, Holothuria scabra, and Actinopyga lecanora). The average number of kilograms harvested per hour per trip ranges from 0.21 (Holothuria fuscopunctata) to 2.71 (Holothuria scabra), while the average size of commonly gathered sea cucumber varies among species with Holothuria lecanora showed an average length (29.26 cm) greater than recorded 24 cm. Processing mainly involves washing, slicing, boiling, drying and packing. Processed sea cucumbers or trepan were sold to middlemen or direct buyers who usually offered higher prices (36.36% up to 69.20%) than the former. Problems encountered by sea cucumber gatherers and traders include a decline in total catch, a shift in area of collection from intertidal zones to deeper waters, an increase in the number of hours spent in finding and gathering sea cucumbers, the use of compressors in gathering, the decline of larger species and gathering of smaller sizes in huge amount, the absence of conservation program for sea cucumber, and the lenient implementation of government policies with regards to coastal resources management.
