An accurate, predictive understanding of protein-DNA binding specificity is crucial for the successful design and engineering of novel protein-DNA binding complexes. In this review, we summarize recent studies that use atomistic representations of interfaces to predict protein-DNA binding specificity computationally. Although methods with limited structural(More)
PURPOSE To evaluate the effects of photodynamic therapy (PDT) on chronic central serous chorioretinopathy (CCSC) by measuring the mean choroidal thickness (MCT) and the lumen area of abnormal choroidal vessels (LAACV). METHODS A total of 36 eyes of 18 patients with monocular CCSC were included in this study. The CCSC eyes received PDT with a half dose(More)
The human cytochrome P450 1A2 is an important drug metabolizing and procarcinogen activating enzyme. An experimental study found that a peripheral mutation, F186L, at ∼26 Å away from the enzyme's active site, caused a significant reduction in the enzymatic activity of 1A2 deethylation reactions. In this paper, we explored the effects of this mutation by(More)
PURPOSE To investigate near-infrared reflectance (NIR) findings in central serous chorioretinopathy (CSCR) and to predict the choroidal vascular diffuse hyperpermeability (CVDHP) by NIR and enhanced depth imaging spectral-domain optical coherence tomography (EDI SD-OCT) noninvasively. METHODS Retrospective analysis of 52 eyes of 50 CSCR patients with(More)
The influenza A virus matrix protein 2 (M2 protein) is a pH-regulated proton channel embedded in the viral membrane. Inhibition of the M2 proton channel has been used to treat influenza infections for decades due to the crucial role of this protein in viral infection and replication. However, the widely-used M2 inhibitors, amantadine and rimantadine, have(More)
Two alternative binding sites of adamantane-type drugs in the influenza A M2 channel have been suggested, one with the drug binding inside the channel pore and the other with four drug molecule S-binding to the C-terminal surface of the transmembrane domain. Recent computational and experimental studies have suggested that the pore binding site is more(More)
Diabetic retinopathy (DR) is the leading cause of visual impairment and blindness in working-aged people. Several studies have suggested that glomerular filtration rate (GFR) was correlated with DR. This is a hospital-based study and the aim of it was to examine the relationship between the GFR and DR in patients with type 2 diabetes mellitus (T2DM). We(More)
PURPOSE To describe the pathoanatomy of diabetic choroidopathy (DC) in pre-diagnosed diabetic retinopathy (DR) cases and to provide angiographic and optical evidence for DC using indocyanine green angiography (ICGA) and enhanced depth imaging spectral-domain optical coherence tomography (EDI SD-OCT). METHODS A retrospective analysis of 80 eyes from 40 DR(More)
A new method for the determination of diazepam was proposed based on its polarographic catalytic wave in the presence of persulfate. In 0.20 M NaAc-HAc (pH 4.7)-1.0 x 10(-2) M K(2)S(2)O(8) supporting electrolyte, the reduction wave of diazepam with peak potential -0.89 V (versus SCE) was catalyzed, producing a parallel catalytic wave. The peak current of(More)
The type A influenza virus matrix protein 2 (M2) is a highly selective proton channel in the viral envelope. Because of its crucial role in viral infection and replication, the M2 channel has been a target of anti-influenza drugs. Due to the occurrence of drug-resistant mutations in the M2 channel, existing anti-influenza drugs that block the M2 channel,(More)
