Proteoglycans (PGs), components of extracellular matrix (ECM), play an important role in modulating the structure and regulating the functions of the skin. The timely turnover of PGs influence the development and differentiation of cells. Wound healing also depends on the level of PGs which if not adequate leads to abnormal scars. The role of PGs in different phases of wound healing and their i...

Objective Indications for preimplantation genetic diagnosis (PGD)/preimplantation genetic screening (PGS) cycles and clinical outcomes were evaluated at CHA Gangnam Medical Center. Methods This is retrospective cohort study. All patients (n=336) who went through in vitro fertilization (IVF)-PGD/PGS cycles (n=486) between January 2014 and December 2015 were included in Fertility Center of CHA ...

Poly(glycerol sebacate) (PGS) continues to attract attention for biomedical applications owing its favorable combination of properties. Conventionally polymerized by a two-step polycondensation glycerol and sebacic acid, variations synthesis parameters, reactant concentrations or specific chemical modifications, PGS materials can be obtained exhibiting wide range physicochemical, mechanical, mo...

Poly(glycerol sebacate) (PGS) is an elastomeric polymer which is attracting increasing interest for biomedical applications, including cartilage regeneration. However, its limited mechanical properties and possible negative effects of its degradation byproducts restrict PGS for in vivo application. In this study, a novel PGS-bioactive glass fiber (F18)-reinforced composite was developed and cha...

BACKGROUND Paraglottic space (PGS) is a connective tissue compartment of the larynx and is important in the extension of laryngeal cancer. It communicates with the preepiglottic space superiorly and with the extralaryngeal region inferiorly through the gap within the cricothyroid membrane. Transglottic cancer of the larynx, which spreads within PGS, is characterized by a high incidence of laryn...

The properties of penumbral grains (PGs) in a medium-size sunspot are studied from a 4.5 hour observation series acquired on 5 June 1993 at the Swedish Vacuum Solar Telescope, La Palma. The application of an image segmentation procedure and a feature tracking algorithm on a movie of 360 frames yields proper motions, intensities, and lifetimes for a set of 469 PGs. Almost 3/4 of the PGs move tow...

Posterior glottic stenosis (PGS), of which the most common cause is tracheal intubation, often misdiagnosed as bilateral vocal cord paralysis. We herein report a case PGS that occurred after treatment with COVID-19 long-term intubation. The patient underwent tracheostomy and endoscopic resection showed improvement in dyspnea. epidemic expected to increase intubation cases severe laryngeal injur...

Background: Smoking and other forms of tobacco use remain the most significant worldwide public health problem. The dental practice is being identified as potential location for smoking cessation activity. Nicotine replacement therapy (NRT) promotes the chances of tobacco cessation, however, evidence related to prescription of the NRT in dental settings is lacking. This study aimed to assess an...
