Jaeyoon Kim, Suhyuk Um, Dongbo Min
2D complex Gabor filtering has found numerous applications in the fields of computer vision and image processing. Especially, in some applications, it is often needed to compute 2D complex Gabor filter bank consisting of filtering outputs at multiple orientations and frequencies. Although several approaches for fast Gabor filtering have been proposed, they focus primarily on reducing the runtime for performing filtering once at specific orientation and frequency. To obtain the Gabor filter bank, the existing methods are repeatedly applied with respect to multiple orientations and frequencies...

BACKGROUND: Chitosan is a derivative form of chitin, which is the major component of exoskeletons of arthropods and cell walls of fungi. Antimicrobial activity of chitosan against lepidopterans, aphids, fungi and bacteria has been extensively investigated, but only one report on the termiticidal effect of chitosan on termites has been published. In this study, we examine the termiticidal activity of chitosan by exposing single colonies of Reticulitermes flavipes (Kollar) and Reticulitermes virginicus Banks to wood treated with 6 different concentrations of chitosan solutions...

Much of our current state of knowledge concerning sex chromosome evolution is based on a handful of 'exceptional' taxa with heteromorphic sex chromosomes. However, classifying the sex chromosome systems of additional species lacking easily identifiable, heteromorphic sex chromosomes is indispensible if we wish to fully understand the genesis, degeneration, and turnover of vertebrate sex chromosomes. Squamate reptiles (lizards and snakes) are a potential model clade for studying sex chromosome evolution as they exhibit a suite of sex determining modes yet most species lack heteromorphic sex chromosomes...

Metabolism of 25-hydroxyvitamin D3 (25OHD3) plays a central role in regulating the biological effects of vitamin D in the body. Although cytochrome P450-dependent hydroxylation of 25OHD3 has been extensively investigated, limited information is available on the conjugation of 25OHD3. In the present study, we report that 25OHD3 is selectively conjugated to 25OHD3-3-O-sulfate by human sulfotransferase 2A1 (SULT2A1) and that the liver is a primary site of metabolite formation. At a low (50 nM) concentration of 25OHD3, 25OHD3-3-O-sulfate was the most abundant metabolite, with an intrinsic clearance approximately 8-fold higher than the next most efficient metabolic route...

Highly inbred C57BL/6 mice show wide variation in their degree of insulin resistance in response to diet-induced obesity even though they are almost genetically identical. Here we employed transcriptional profiling by RNA sequencing (RNA-Seq) of visceral adipose tissue (VAT) and liver in young mice to determine how gene expression patterns correlate with the later development of high-fat diet (HFD)-induced insulin resistance in adulthood. To accomplish this goal, we partially removed and banked tissues from pubertal mice...

It is widely accepted that the therapeutic potential of stem cells can be largely mediated by paracrine factors, also included into exosomes. Thus, stem cell-derived exosomes represent a major therapeutic option in regenerative medicine avoiding, if compared to stem cells graft, abnormal differentiation and tumor formation. Exosomes derived from mesenchymal stem cells (MSC) induce damaged tissue repair, and can also exert immunomodulatory effects on the differentiation, activation and function of different lymphocytes...

BACKGROUND: The severe form of equine asthma is associated with pathological changes of the peripheral airways and pulmonary parenchyma that are only partly described. Also, the relationship between these structural alterations and the percentage of neutrophils found within the airway lumen, assessed by bronchoalveolar lavage fluid (BALF) cytology, remains ill-defined. OBJECTIVE: To examine the histological lesions associated with equine asthma during disease exacerbation and remission, and their relationship with lung function and BALF neutrophilia...

In the context of geological carbon sequestration (GCS), carbon dioxide (CO2 ) is often injected into deep formations saturated with a brine that may contain dissolved light hydrocarbons, such as methane (CH4 ). In this multicomponent multiphase displacement process, CO2 competes with CH4 in terms of dissolution, and CH4 tends to exsolve from the aqueous into a gaseous phase. Because CH4 has a lower viscosity than injected CO2 , CH4 is swept up into a 'bank' of CH4 -rich gas ahead of the CO2 displacement front...

Malaria is one of the exclusion criteria used in selecting tissue donors and the absence of this information can lead to rejection of tissues for transplant. The studies on the malaria parasite have been confined to low dose attenuation of parasites in blood for transfusion purposes. There is no published information relating to the inactivation of malaria parasites with irradiation for the sterilisation of tissues. A dose-surviving parasite population following radiation was replotted using D0 value from a published paper whereby D10 value of 41 Gy was obtained...

Successful infection with Human Papillomaviruses requires mitosis, when incoming viral genomes gain access to nuclear components. However, very little is known about how long HPV particles can remain infectious in non-dividing cells or in which cellular compartments these viruses may reside. To investigate these questions we have used BJ cells as a reversible model of senescence and show that HPV-16 can only infect early-passage proliferating cells. Late-passage senescent cells are resistant to HPV infection, but this can be reversed by inducing cell cycle re-entry with a p53 siRNA...

Canine sulfonamide hypersensitivity (HS) has been associated with a variant in the cytochrome b5 reductase gene (CYB5R3 729A>G), which encodes a drug-detoxifying enzyme. Study objectives were to determine variant allele frequency in Doberman Pinschers (DOBE), a breed which may be predisposed to sulfonamide HS, and to characterize the effects of CYB5R3 729G on gene expression and function. CYB5R3 729A>G allele frequencies were compared between DOBE (n = 24) vs. non-Doberman (non-DOBE; n = 60) dogs...
