We investigated the relationship between neuropsychological disturbance, assessed using the global assessment of functioning (GAF) and the ADHD-rating scale (ADHD-RS), paroxysmal EEG abnormalities, and treatment with valproate sodium (VPA) in children with both attention deficit hyperactivity disorder (ADHD) and paroxysmal abnormality (PA). Participants with ADHD but without obvious epilepsy were recruited between April 1, 2003 and March 31, 2008. Paroxysmal abnormality was scored by measuring the spike frequency.

Chronic intraocular pressure (IOP) elevation was induced by laser trabeculoplasty twice at 2-week intervals in the left eyes of 4 common marmosets. IOP was measured before and at 4, 7, 8, 11, 13 weeks after first laser treatment, and ophthalmoscopic examinations were also performed.

Method: VRQoL score was surveyed in 164 patients with glaucoma using the 'Sumi questionnaire'. A binocular VF was created from monocular VFs by using the integrated VF (IVF) method.

Background: Superficial temporal artery-to-middle cerebral artery (STA-MCA) anastomosis is a common procedure for neurosurgeons. The surgery necessarily requires accurate and speedy manipulation of microscope, for which a specific training is needed. Unexpected bypass occlusion sometimes happen during surgery.

Methods: The questionnaire was divided into three parts: details of the child and their family; medical management of the child before reaching hospital; and parental thoughts and actions when the child experienced convulsions.
Object: Blockade of Ca(++)-permeable α-amino-3-hydroxy-5-methyl-4-isoxazolepropionate receptor (AMPAR) inhibits the proliferation of human glioblastoma by inhibiting Akt phosphorylation, which is independent of the phosphatidylinositol 3-kinase pathway. Inhibiting platelet-derived growth factor receptor (PDGFR)-mediated phosphorylation causes growth inhibition in glioblastoma cells. The authors of this study investigated the effects of YM872 and AG1296, singly and in combination and targeting different pathways upstream of Akt, on Akt-mediated tumor growth in glioblastoma cells in vivo and in vitro.

Methods: A prospective randomized multicentre single-masked comparative study. Patients with open-angle glaucoma or ocular hypertension who had been treated with BAK-preserved latanoprost 0.
Purpose: Although useful for reducing intraocular pressure (IOP), bimatoprost (BIM) can cause deepening of the upper eyelid sulcus (DUES), one of the symptoms of prostaglandin-associated periorbitopathy (PAP). We investigated recovery from BIM-induced DUES after switching treatment to latanoprost (LAT).
Design: Prospective, observer-masked, open-label study.
Purpose: Recent studies have indicated that accumulation of amyloid β(1-42) (Aβ(1-42)), which is associated with the progression of Alzheimer disease, may also be responsible for retinal ganglion cell death in glaucoma. The purpose of this study was to investigate the expression and localization of Aβ(1-42) in the retina and the optic nerve head (ONH) of monkeys with experimental glaucoma.
Methods: Five cynomolgus monkeys with a glaucomatous left eye at 4, 9, 11, 15, and 24 weeks after laser photocoagulation treatment were studied by immunohistochemical methods.
Purpose: In epilepsy with continuous spikes and waves during slow sleep (CSWS), which is a representative epileptic syndrome of secondary bilateral synchrony (SBS), the urgent suppression of this electroencephalographic (EEG) abnormality may be necessary to prevent the progression of neuropsychological impairments. The purpose of this study was to determine the efficacy of levetiracetam (LEV) on SBS, seizure frequency, and neuropsychological impairments in children with refractory epilepsy.
Methods: Eleven (seven male and four female) patients with refractory epilepsy with SBS on EEG, aged between 4.
Background: The high occurrence of epilepsy in children with autism spectrum disorders (ASD) is a clear indication that ASD has a neurobiological basis. The current understanding of the association between epilepsy and ASD is still limited, but from a clinical point of view, this association should not be overlooked.
Aims: We investigated the electroencephalogram (EEG) paroxysmal abnormality in children with ASD and the incidence of later development of epilepsy.
Background: Periostin, a matricellular protein, serves as a regulator of wound healing and fibrosis. The role of periostin in the pathogenesis of systemic sclerosis (SSc) is unknown.
Objective: To determine periostin levels in association with severity of skin fibrosis in patients with SSc.
Purpose: To analyze the influence of oxidative stress on retinal ganglion cells (RGCs) by using a selective culture system of rat RGCs.
Methods: Rat RGCs were purified by a two-step immunopanning procedure and cultured either with or without antioxidant (AO) compounds. Reactive oxygen species (ROS) in RGCs were analyzed using dihydroethidium.
Purpose: To establish an animal model for the easy assessment of pressure-dependent damage to retinal ganglion cells (RGCs) using the B6.Cg-TgN(Thy1-CFP)23Jrs/J transgenic mouse strain (CFP mouse), which expresses cyan fluorescent protein (CFP) in RGCs, and to evaluate pressure-dependent RGC death.
Methods: In 20 CFP mice, right eyes were selected to receive laser-induced ocular hypertension eye and the contralateral eyes remained untouched to serve as controls.
Purpose: To investigate the prognostic factors responsible for the progression of visual field defects (VFDs) in patients with normal-tension glaucoma (NTG) treated with topical antiglaucoma medications.
Patients And Methods: A total of 92 eyes in 92 NTG patients treated with only topical antiglaucoma medications for ≥ 5 years were retrospectively analyzed. To identify subfield-based prognostic factors, the central 30-degree visual field (Humphrey Field Analyzer) was divided into 6 subfields: upper and lower arcuate, paracentral, and cecocentral subfields.
Purpose: To clarify the mechanism of prostaglandin (PG) analogue-dependent relaxation in ciliary arteries from wild-type (WT) and prostanoid receptor-deficient mice.
Methods: The intracellular-free calcium concentration ([Ca(2+)](i)) in isolated WT mouse ciliary arteries was measured by fluorescence photometry. Reduction of [Ca(2+)](i) leading to vascular relaxation by PG analogues latanoprost, isopropyl unoprostone, or tafluprost was compared to the maximum increase of [Ca(2+)](i) by 50 mM KCl.
