Agmatine (decarboxylated arginine) has been known as a natural product for over 100 years, but its biosynthesis in humans was left unexplored owing to long-standing controversy. Only recently has the demonstration of agmatine biosynthesis in mammals revived research, indicating its exceptional modulatory action at multiple molecular targets, including(More)
AIM To compare the diagnostic ability to detect glaucomatous changes between peripapillary retinal nerve fibre layer (RNFL) thickness and the macular ganglion cell complex (GCC) in highly myopic patients using Fourier domain optical coherence tomography. METHODS Participants, consecutively enrolled from January 2009 to June 2009, were imaged with(More)
PURPOSE Although laparoscopic surgery may permit earlier recovery compared with open surgery, no published randomized controlled trial has investigated the benefit of a multimodal rehabilitation program after laparoscopic colonic resection. This study aimed to evaluate the efficacy of a rehabilitation program after laparoscopic colon surgery in the context(More)
OBJECTIVE To evaluate and compare time-domain (Stratus) and spectral-domain (Cirrus; both Carl Zeiss Meditec, Dublin, California) optical coherence tomography (OCT) for the detection of localized retinal nerve fiber layer (RNFL) defects in patients with open-angle glaucoma. METHODS Patients with localized RNFL defects and age-matched normal control(More)
The effect of hypoxia on the release of tumor necrosis factor-α (TNF-α) in transformed rat retinal ganglion cells (RGCs) and the effect of agmatine on the hypoxia-induced production of TNF-α in RGCs were evaluated. RGCs were cultured under hypoxic conditions with 5% oxygen, with or without 100 μM agmatine. The expression levels of TNF-α and its receptor-1(More)
OBJECTIVE Open-angle glaucoma (OAG) is one of the major chronic diseases involving the optic nerve. However, little is known about the association between vitamin D and OAG. The present study was conducted to test the hypothesis that lower vitamin D status is associated with greater prevalence of OAG. DESIGN Cross-sectional study. Multivariable logistic(More)
To better understand the neuroprotective actions of agmatine in ischemic insults, its effects on astrocytes were investigated using an in vitro oxygen-glucose deprivation (OGD) model. After primary culture, cortical astrocytes were moved into a closed anaerobic chamber and incubated in glucose-free culture media. 4 h later, the cells were restored to(More)
Although early rehabilitation programs have been reported to be effective after laparoscopic colectomy, there is no report of the efficacy of rehabilitation programs after rectal cancer surgery. This study was designed to evaluate the efficacy of an early rehabilitation program after laparoscopic low anterior resection for mid or low rectal cancer in a(More)
PURPOSE To compare perimacular ganglion cell complex (GCC) parameters between patients with normal tension glaucoma (NTG) and primary open-angle glaucoma (POAG). METHODS Participants, consecutively enrolled from January 2009 to June 2009, underwent optical coherence tomographic imaging with RTVue-100 (Optovue Inc, Fremont, CA). Optic nerve head (ONH)(More)
PURPOSE To compare the effectiveness of Humphrey Matrix perimetry, GDx VCC, Stratus OCT, and retinal nerve fiber layer (RNFL) photography using the Heidelberg Retina Angiograph 1 (HRA1) for early glaucoma detection. DESIGN Cross-sectional comparative study. PARTICIPANTS Seventy-two primary open-angle glaucoma patients with early-stage visual field(More)
