Long-term Efficacy of Dacryoendoscopy-guided Recanalization and Silicone Tube Intubation.

Purpose: To investigate the long-term efficacy of dacryoendoscopy-guided recanalization and silicone tube intubation in patients with obstruction in the lacrimal drainage system and to identify factors related to surgical outcome.

Methods: We retrospectively reviewed the medical records of patients with primary nasolacrimal duct obstruction and canalicular obstruction who underwent dacryoendoscopy-guided recanalization and silicone tube intubation between August 2014 and March 2016. Factors related to surgical outcome were examined and compared between the success group (eyes with complete response and partial response) and the failure group.

Comparison of digital subtraction dacryocystography and dacryoendoscopy in patients with epiphora.

Objective: To assess the diagnostic information provided by digital subtraction dacryocystography (DCG) and dacryoendoscopy in patients with epiphora.

Methods: Sixty-eight lacrimal systems of 34 patients with epiphora were prospectively studied. Patients were initially examined with syringing, followed by digital subtraction DCG and dacryoendoscopy to confirm the diagnosis.

Crystallization and Martensitic Transformation Behavior of Ti-Ni-Si Alloy Ribbons Prepared via Melt Spinning.

Ti-(50-x)Ni-xSi (at%) (x = 0.5, 1.0, 3.

A chromogenic molecular capsule attributable to dipolar amide resonance structure.

A new chromogenic, self-assembled molecular capsule G@22 is developed by introducing four (N,N-dimethyl-4-aminophenyl) azobenzyl moieties on the upper rim of a resorcin[4]arene-based amidoimino-cavitand. The tuning of conjugation between amido and (N,N-dimethyl-4-aminophenyl)azobenzyl groups by acid-base titration allows naked-eye detection of molecular capsule formation.

Strain-dependent response to Cu(2+) in the expression of laccase in Pycnoporus coccineus.

The effects of Cu(2+) on the activity and expression of laccase were investigated in seven different strains of Pycnoporus coccineus collected from different regions in Korea. Cu(2+) was toxic to mycelial growth at concentrations greater than 0.5 mM CuSO4 and showed complete growth inhibition at 1 mM in the liquid culture.

Isolation of Fungal Pathogens to an Edible Mushroom, Pleurotus eryngii, and Development of Specific ITS Primers.

Fungal pathogens have caused severe damage to the commercial production of Pleurotus eryngii, the king oyster mushroom, by reducing production yield, causing deterioration of commercial value, and shortening shelf-life. Four strains of pathogenic fungi, including Trichoderma koningiopsis DC3, Phomopsis sp. MP4, Mucor circinelloides MP5, and Cladosporium bruhnei MP6, were isolated from the bottle culture of diseased P.

Comparison of phaco-chop, divide-and-conquer, and stop-and-chop phaco techniques in microincision coaxial cataract surgery.

Purpose: To compare the outcomes of coaxial microincision cataract surgery (MICS) performed with 3 phacoemulsification techniques (phaco-chop, divide-and-conquer, and stop-and-chop) according to cataract density.

Setting: Bucheon St. Mary's Hospital, College of Medicine, Catholic University of Korea, Seoul, South Korea.

Versatile self-assembled molecular capsule formation of a resorcin[4]arene-based benzamidoiminocavitand.

The facile synthesis of a resorcin[4]arene-based imino-cavitand with benzamido moieties and its self-assembly into molecular capsules are reported. Benzamido-iminocavitand efficiently self-assembled into thermally inert molecular capsules in the presence of suitable guests via the eight intermolecular N-H···O=C hydrogen bonds.

The orientation of the lacrimal fossa to the bony nasolacrimal canal: an anatomical study.

Purpose: To examine the relative positions of the lacrimal fossa (LF) and the bony nasolacrimal canal (BNLC) in relation to each other and a reference plane.

Methods: Forty-two orbits and BNLCs from 21 Asian cadavers (9 men and 12 women; average age at death, 84.4 years; range, 70-99 years) had been fixed in 10% buffered formalin before use.

Profile of Xeomin® (incobotulinumtoxinA) for the treatment of blepharospasm.

Even though conventional botulinum neurotoxin (BoNT) products have shown successful treatment results in patients with benign blepharospasm (BEB), the main, potential long-term side effect of BoNT use is the development of immunologic resistance due to the production of neutralizing antibody to the neurotoxin after repeated injections. Xeomin(®) (incobotulinumtoxinA), a unique botulinum neurotoxin type A (BoNT/A) drug free of complexing proteins otherwise contained in all conventional BoNT/A drugs, was recently approved by US Food and Drug Administration for the treatment of cervical dystonia or blepharospasm in adults. The newly approved BoNT/A drug may overcome this limitation of previous conventional products, since it contains pure neurotoxin (150 kDa) through a manufacturing process that separates it from complexing proteins such as hemagglutinins produced by fermentation of Clostridium botulinum.

Changes to upper eyelid orbital fat from use of topical bimatoprost, travoprost, and latanoprost.

Purpose: To confirm the possible mechanism by which topical prostaglandin antiglaucoma drugs cause a deep superior sulcus.

Methods: Among patients who used bimatoprost (Lumigan), latanoprost (Xalatan), or travoprost (Travatan) and who developed a deep upper lid sulcus, 18 eyes of 11 patients (mean age, 58.2 ± 8.

Development of a nonintrusive blood pressure estimation system for computer users.

An individual's cardiovascular health is important. The measurement of blood pressure (BP) can be performed nonintrusively during normal daily activities. A study was designed to estimate systolic BP by measuring pulse arrival time (PAT) nonintrusively.

Unconstrained pulse transit time measurement system for computer users.

Pulse Transit Time (PTT) is a simple non-invasive method to evaluate vascular function using photoplethysmography(PPG) and electrocardiography(ECG). This study introduces unconstrained PTT measurement method for computer users and evaluates that. The proposed system consists of chair and mouse those can measure ECG and PPG respectability.

A Preliminary Study for Unconstrained Pulse Arrival Time (PAT) Measurement on a Chair.

A method of measuring the pulse arrival time (PAT) non-consciously on a chair is proposed. In this method, the electrically non-contact ECG measurement system and the air cushion with balancing tubes are used. In this paper, the correlation between the typical PAT and the unconstrained PATs (A-PATs) are compared.
