A Protocol to Acquire the Degenerative Tenocyte from Humans.

Tendinopathy, a painful condition that develops in response to tendon degeneration, is on the rise in the developed world due to increasing physical activity and longer life expectancy. Despite its increasing prevalence, the underlying pathogenesis still remains unclear, and treatment is generally symptomatic. Recently, numerous therapeutic options, including growth factors, stem cells, and gene therapy, were investigated in hopes of enhancing the healing potency of the degenerative tendon.

Long-term Surgical Outcomes of Initial Postoperative Overcorrection in Adults with Intermittent Exotropia.

Purpose: To evaluate the relationship between initial postoperative overcorrection and long-term surgical success in exotropia patients.

Methods: The medical records of 46 patients who underwent surgery for intermittent exotropia after the age of 18 were enrolled. Enrolled patients also had at least 2 years of postoperative follow-up.

Investigation of the Changes in Refractive Surgery Trends in Korea.

Purpose: To evaluate changes in clinical practice in the field of refractive surgery in Korea over the past 10 years.

Methods: A survey consisting of 59 multiple-choice questions regarding the preferred types of refractive surgery, excimer laser machine, and presbyopia surgery was mailed to 742 members of the Korean Society of Cataract and Refractive Surgery in January 2016, and 50 members responded to the survey. These data were compared with the 2005 or 2007 survey results.

Sex differences in the effect of aging on dry eye disease.

Purpose: Aging is a major risk factor in dry eye disease (DED), and understanding sexual differences is very important in biomedical research. However, there is little information about sex differences in the effect of aging on DED. We investigated sex differences in the effect of aging and other risk factors for DED.

Serological and molecular prevalence of canine vector-borne diseases (CVBDs) in Korea.

Background: Previous surveys in dogs from Korea indicated that dogs are exposed to a variety of vector- borne pathogens, but perception for a nation-wide canine vector-borne disease (CVBD) occurrence has been missing. We report here results of both serological and molecular prevalence studies for major CVBDs of dogs from all over the South Korean Peninsula except for Jeju Island.

Results: Serological survey of 532 outdoor dogs revealed the highest prevalence for Dirofilaria immitis (25.

Size distribution and settling velocities of suspended particles in a tidal embayment.

Field studies were carried out to investigate seasonal and bay-wide variations in the particle size distributions (PSDs) and settling velocities of suspended particles in Newport Bay, the second largest tidal embayment in southern California. Maximum Entropy Classification (MEC) of the data identified three PSD groups: (1) suspended particles with a single mode around 10-20 μm (Group 1), (2) suspended particles with a single mode similar to Group 1, but shifted to smaller particle sizes (Group 2), and (3) suspended particles with a coarse mode at around 100 μm (Group 3). The three PSD groups have distinct seasonal and spatial patterns, and different size-settling velocity relationships, consistent with the hypothesis that Newport Bay longitudinally fractionates allochthonous particles from its tributaries by both size and settling velocity, and generates large and fast settling autochthonous particles, probably in the form of biological debris.

Evaluation of chemical, molecular, and traditional markers of fecal contamination in an effluent dominated urban stream.

In this paper we present a quantitative sanitary survey of the Middle Santa Ana River, in southern California, utilizing a variety of source tracking tools, including traditional culture-dependent fecal markers (Enterococcus and Escherichia coli by IDEXX), speciation of enterococci isolates, culture-independent fecal markers (human-specific HF183 Bacteroides and Enterococcus by quantitative polymerase chain reaction, qPCR), and chemical markers of sewage and wastewater (nutrients, enantiomeric fraction (EF) of propranolol and ethylenediaminetetraacetic acid). To facilitate comparison of these different methods, data are interpreted in a loading (i.e.

Use of salinity mixing models to estimate the contribution of creek water fecal indicator bacteria to an estuarine environment: Newport Bay, California.

The contribution of freshwater discharge to fecal indicator bacteria (FIB) impairment of an estuarine environment can be approximated from simple, two end-member mixing models using salinity as a tracer. We conducted a yearlong time series investigation of Newport Bay, a regionally important estuarine embayment in southern California, assessing the concentrations of FIB, specifically Escherichia coli and enterococci bacteria, and salinity. In total, eight within-bay stations and one offshore control site were sampled nearly once per week and the three tributaries draining into Newport Bay were sampled approximately daily.

Size distribution, sources, and seasonality of suspended particles in southern California marine bathing waters.

In this paper we define seasonal and along-shore variations in suspended particle size distributions (PSDs) at two marine bathing beaches in southern California, using a low-angle light scattering instrument (LISST). Empirical Orthogonal Function (EOF) analysis of the LISST data set (n = 55 651) identified three particle size modes that collectively account for > 90% of the variance in the de-meaned PSD data at six sites along the shoreline at Huntington Beach and Newport Beach: a dinoflagellate mode, a large particle mode, and a small particle mode. These three modes exhibit distinct seasonal patterns, and along-shore distributions, reflecting both the sources of particles and environmental factors that trigger their occurrence.

Flow fingerprinting fecal pollution and suspended solids in stormwater runoff from an urban coastal watershed.

Field studies were conducted to characterize the concentration vs streamflow relationships (or "flow fingerprints") of fecal pollution and suspended solids in stormwater runoff from the Santa Ana River watershed, the largest watershed in southern California. The concentrations of fecal indicator bacteria and F+ coliphages (viruses infecting E. coli) exhibit little-to-no dependence on streamflow rates, whereas the concentrations of total suspended solids (TSS) exhibit a very strong (power-law) dependence on streamflow rates.

Coastal water quality impact of stormwater runoff from an urban watershed in southern California.

Field studies were conducted to assess the coastal water quality impact of stormwater runoff from the Santa Ana River, which drains a large urban watershed located in southern California. Stormwater runoff from the river leads to very poor surf zone water quality, with fecal indicator bacteria concentrations exceeding California ocean bathing water standards by up to 500%. However, cross-shore currents (e.

The Prevalence Of Intestinal Helminthes In Inhabitants Of Cheju Do.

The authors examined 3,169 fecal specimens from inhabitants of seven localities such as City, Eups and Myons in Cheju Do on July 1970 with cellophane thick smear technique. The results were analysed and summarized as follows: 1) The overall egg positive rate of helminths was 82.2% and it was attributed to high rates of soil-transmitted helminths as in case of other parts in Korea.

Santonin-Kainic Acid Complex As A Mass Chemotherapeutic Of Ascaris Lumbricoides Control In Korea.

Santonin-kainic acid complex was evaluated as a chemotherapeutic of the mass treatment of the Ascaris lumbricoides infection in Korea. The results could be summarized as follows: 1) The negative conversion rate was 82.9% in average in 4 treated groups.
