Article Synopsis
  • Korean landrace red peppers, particularly the Subicho variety, are vital in Korean cuisine but are vulnerable to biotic stresses, affecting their quality and yield.
  • Using NMR spectroscopy and multivariate analysis, researchers identified 42 metabolites with significant differences between healthy and stressed Subicho peppers, noting lower sucrose and higher amino acid levels in stressed samples.
  • The study highlights unique metabolic adaptations in Subicho peppers that suggest resilience to stress, providing insights for targeted breeding programs to improve quality and economic viability in the food industry.

Chili peppers ( L.) are economically valuable crops belonging to the Solanaceae family and are popular worldwide because of their unique spiciness and flavor. In this study, differences in the metabolomes of landrace (Subicho) and disease-resistant pepper cultivars (Bulkala and Kaltanbaksa) widely grown in Korea are investigated using a H NMR-based metabolomics approach.

Aims: Sarcopenia is characterized by a gradual loss of skeletal muscle mass and strength with increased adverse outcomes. Recently, large-scale epidemiological studies have demonstrated a relationship between several chronic disorders and ocular pathological conditions using an oculomics approach. We hypothesized that sarcopenia can be predicted through eye examinations, without invasive tests or radiologic evaluations in the context of predictive, preventive, and personalized medicine (PPPM/3PM).

Article Synopsis
  • The study focused on how calcium supplementation affects heart health in Korean individuals with low calcium intake.
  • It found that those taking calcium supplements had a significantly higher risk of acute myocardial infarction, ischemic stroke, and death compared to individuals not taking supplements.
  • Researchers suggest that calcium supplements for osteoporosis treatment may need to be given with caution due to the potential cardiovascular risks involved.

Article Synopsis
  • Highly conductive 3D ordered mesoporous NiS-MoS/N-doped graphitic carbon (NGC) microspheres are developed for use as anodes in Na-ion batteries, featuring stable phases and uniform mesopores for better performance.
  • The P-NiMoS/C microspheres show impressive initial discharge capacities at varying current densities, maintaining a solid discharge capacity after extensive cycling, which surpasses other existing non-mesoporous anode configurations.
  • Their superior performance is linked to enhanced Na ion diffusion, reduced volume stress during use, and improved electrical conductivity, paving the way for future advancements in battery technology.

Human activities, such as dam construction and reclamation, can affect sedimentation rates as well as sediment topography and transport in estuaries such as the Nakdong River Estuary. To investigate the sedimentation history, two sediment cores (1-2 m long) were sampled in tidal flats of the estuary. In addition, surface sediments were collected to study present sedimentation environments that appear to be three environments locally: 1) fine-grained sediment deposition; 2) sediments under stronger hydraulic energy; and 3) sandy sediments with good sorting.

We retrospectively reviewed the cases in which complications occurred during below-the-knee (BTK) endovascular treatments that were performed at our hospital from 2005 to 2014. Several interesting cases have been described herein. All the patients had diabetes and non-healing wounds on their feet and/or rest pain in their foot or leg, and therefore, endovascular treatment was performed for the BTK arteries of the affected lower extremity.

Myxomas can be divided into two groups: those derived from the facial skeleton, and those derived from external skeletal soft tissue. Soft tissue myxomas of the head and neck are uncommon, with fewer than 50 cases reported. In any form and location, myxoma of parotid gland is rare.

Background: To date, a variety of surgical approaches have been used to reconstruct the medial orbital wall fracture. Still however, there is still a controversy as to their applicability because of postoperative scars, injury of anatomical structures and limited visual fields. The purpose of this study was to introduce a useful additional medial subbrow approach for better reduction and securement more accurate implant pocket of medial orbital wall fracture with the subciliary technique.

Background: We conducted this study to identify factors that may prolong the length of the hospital stay (LHS) in patients with diabetic foot (DF) in a single-institution setting.

Methods: In this single-center retrospective study, we evaluated a total of 164 patients with DF, and conducted an intergroup comparison of their baseline demographic and clinical characteristics, including sex, age, duration of diabetes, smoking status, body mass index, underlying comorbidities (e.g.

Background: The ultimate goal of craniofacial reconstructive surgery is to achieve the most complete restoration of facial functions. A bioabsorbable fixation system which does not need secondary operation for implant removal has been developed in the last decade. The purpose of this study is to share the experience of authors and to demonstrate the efficacy of bioabsorbable mesh in a variety of craniofacial trauma operations.

Background: Various techniques for lengthening short columellae have been used for bilateral cleft nose repair. However, previous methods have not yielded satisfactory results. We performed a full-thickness skin graft to lengthen short columellae during secondary cleft nose repair in adult patients.

Background: Orthognathic surgery is required in 25% to 35% of patients with a cleft lip and palate, for whom functional recovery and aesthetic improvement after surgery are important. The aim of this study was to examine maxillary and mandibular changes, along with concomitant soft tissue changes, in cleft patients who underwent LeFort I osteotomy and sagittal split ramus osteotomy (two-jaw surgery).

Methods: Twenty-eight cleft patients who underwent two-jaw surgery between August 2008 and November 2013 were included.

The spatiotemporal distribution and their mass accumulation rate (MAR) of heavy metals were investigated to evaluate the time-dependent historical trends of heavy metal concentration. The three short cores used for this study were collected from the catchment area (MS-PC5, 60cm length), the central part (MS-PC4, 40cm length) and the offshore (MS-PC2, 60cm length) of the Masan Bay, Korea. The concentration of heavy metals (Co, Ni, Cu, Zn, Cr and Pb) in catchment area is as much as 1.

Background: Frontal sinus fractures, particularly anterior sinus fractures, are relatively common facial fractures. Many agree on the general principles of frontal fracture management; however, the optimal methods of reduction are still controversial. In this article, we suggest a simple reduction method using a subbrow incision as a treatment for isolated anterior sinus fractures.

Background: The aims of alveolar bone grafting are closure of the fistula, stabilization of the maxillary arch, support for the roots of the teeth adjacent to the cleft on each side. We observed nostril base augmentation in patients with alveolar clefts after alveolar bone grafting. The purpose of this study was to evaluate the nostril base augmentation effect of secondary alveolar bone grafting in patients with unilateral alveolar cleft.

Background: Diabetes mellitus tends to have the greatest impact on the smaller vessels and contributes significantly to occlusive disease from the popliteal artery distally.

Purpose: To evaluate the clinical outcomes after a balloon angioplasty with or without stent placement in diabetic patients with critical limb ischemia (CLI) by chronic total occlusion (CTO) limited to below-the-knee (BTK) arteries.

Material And Methods: From August 2005, patients who presented CLI and CTO limited to the BTK arteries, and who underwent endovascular treatment, were included in this study.

A satisfying result is difficult to achieve in the repair of a full-thickness skin defect in the facial area, including the subunits of the nose. A full-thickness skin graft, nasolabial flap, or forehead flap as a major treatment still is used despite its relative potential for secondary contracture, unmatched skin color, hypertrophic scars, and donor-site morbidity. Another option, with good wound-healing power and soft tissue regeneration without skin grafts would be helpful for initiating treatment.
