Chromatin remodeling-related proteins, such as linker histone H1, involving in fruit ripening and stress responses are poorly understood. In the present study, a novel cDNA encoding linker histone H1 gene, designated as MaHIS1 was isolated and characterized from banana fruit. The full-length cDNA sequence was 1,253 bp with an open-reading frame (ORF) of 948(More)
Major depression is thought to originate from maladaptation to adverse events, particularly when impairments occur in mood-related brain regions. Hypothalamus-pituitary-adrenal (HPA) axis is one of the major systems involved in physiological stress response. HPA axis dysfunction and high glucocorticoid concentrations play an important role in the(More)
Birt-Hogg-Dubé syndrome (BHD) is an autosomal dominant cancer syndrome characterised by benign skin tumours, renal tumours, and spontaneous pneumothorax. The gene has been mapped to chromosome 17p11.2 and recently identified, expressing a novel protein called folliculin. We report the clinical and genetic studies of four sporadic BHD cases and four families(More)
Ischemic stroke is currently treated with thrombolytic therapy with a drawback to induce hemorrhagic transformation (HT) if applied beyond its relatively narrow treatment time window. The present study was designed to examine the role of IMM-H004, a derivative of coumarin, in recombinant tissue plasminogen activator (tPA)-induced HT. Rats subjected to 6 h(More)
Aptamers, including DNA, RNA and peptide aptamers, are a group of promising recognition units that can specifically bind to target molecules and cells. Due to their excellent specificity and high affinity to targets, aptamers have attracted great attention in various fields in which selective recognition units are required. They have been used in(More)
New Delhi metallo-β-lactmase-1 (NDM-1) has recently attracted extensive attention for its biological activities to catalyze the hydrolysis of almost all of β-lactam antibiotics. To study the catalytic property of NDM-1, the steady-kinetic parameters of NDM-1 toward several kinds of β-lactam antibiotics have been detected. It could effectively hydrolyze most(More)
Bacterial endotoxin has been known to induce excessive inflammatory responses and acute kidney injury. In the present study, we used a mouse model of endotoxemia to investigate the role of Sirt1 in inflammatory kidney injury. We examined molecular and cellular responses in inducible Sirt1 knockout (Sirt1-/-) mice and wild type littermates (Sirt1+/+) in(More)
Upconversion is an optical process that involves the conversion of lower-energy photons into higher-energy photons. It has been extensively studied since mid-1960s and widely applied in optical devices. Over the past decade, high-quality rare earth-doped upconversion nanoparticles have been successfully synthesized with the rapid development of(More)
Detecting lines from a digital image is very important in image processing. An efficient line detection based on randomized method is presented. Different from the previous HT (Hough Transform) - based methods which vote on a parameter space, this algorithm does not need an accumulator for representing parameter space. The main concept in the proposed(More)
A serious limitation of numerous antitumor drugs is the incapacity to penetrate solid tumors. However, addition of an RGD fragment to peptide drugs might solve this problem. In this study, we explored whether the introduction of a permeability-enhancing sequence, such as iRGD (CRGDK/RGPD/EC) fragments, would enhance the activity of thymosin alpha 1 (Tα1).(More)
