Blue Compact Dwarf (BCD) galaxies are metal poor systems going through a major starburst that cannot last for long. We have identified galaxies which may be BCDs during quiescence (QBCD), i.e., before the characteristic starburst sets in or when it has faded away. These QBCD galaxies are assumed to be like the BCD host galaxies. The SDSS/DR6 database provides ∼21500 QBCD candidates. We also sel...

BACKGROUND Pemphigus vulgaris (PV) is a severe autoimmune blistering disorder characterized by the presence of pathogenic autoantibodies directed against desmoglein-3 (Dsg3), involving specific DR4 and DR6 alleles in Caucasians and DQ5 allele in Asians. The development of sequence-based predictive algorithms to identify potential Dsg3 epitopes has encountered limited success due to the paucity ...

The Maillard Reaction Products (MRPs) are chemical compounds which have been known to be effective in chemoprevention. Death receptors (DR) play a central role in directing apoptosis in several cancer cells. In our previous study, we demonstrated that (E)-2,4-bis(p-hydroxyphenyl)-2-butenal, a MRP product, inhibited human colon cancer cell growth by inducing apoptosis via nuclear factor-κB (NF-κ...

AIMS To determine whether the polymerase chain reaction with sequence specific primers (PCR-SSP) can assign HLA-DR type more accurately than serology in a routine hospital laboratory. METHODS The 93 patients currently awaiting kidney transplants have been DR typed by serology over the past 14 years, 82% within the past five years. They have now been retyped using the PCR-SSP method described ...

HLA molecules, polymorphic membrane glycoproteins, are classified into 2 groups: those expressed on the surface of almost all nucleated cells (HLA class I molecules), and those found on the surface of cells mainly involved in the immune response (HLA, class H molecules) (1). In guinea pigs and mice, the genes that control delayed hypersensitivity reactions have been shown to be linked with thos...

The new generation astronomy digital archives cover large area of the sky at fine resolution in many wavelengths from ultraviolet through optical and infrared. For instance, one of these projects the Sloan Digital Sky Survey is creating a detailed catalog covering more than a quarter of the sky with images measured with five different filters. The size of the data set can be measured in terabyt...

Modern spectroscopic databases provide a wealth of information about the physical processes and environments associated with astrophysical populations. Techniques such as blind source separation (BSS), in which sets of spectra are decomposed into a number of components, offer the prospect of identifying the signatures of the underlying physical emission processes. Principle Component Analysis (...

Context. Determining the metallicities and ages of M31 clusters is fundamental to study formation evolution itself. The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) has carried out a systematic spectroscopic campaign candidates in M31. Aims. We constructed catalogue 346 observed by LAMOST. By combining information LAMOST spectra multi-band photometry, we developed new algo...

Accurate and efficient determination of stellar atmospheric parameters (Teff, logg, [Fe/H]) is essential for large-scale sky survey to conduct Galactic archeology evolution history. This paper proposes a novel data-driven model based on statistical features Catboost algorithm (SCDD). The extracts the spectra by windows, constructs nonlinear mapping between spectral parameters. After being train...
