[Diagnosis of Hypersensitivity Pneumonitis: 2020 Clinical Practice Guideline].

Hypersensitivity pneumonitis (HP) is an interstitial lung disease (ILD) characterized by an inhaled inciting antigen that leads to the inflammation of the lung parenchyma and small airway with immunologic reactions. Over the last decades, the most effective therapeutic option for HP has been limited to antigen avoidance. The differential diagnosis of HP from other ILDs is the beginning of treatment as well as diagnosis.

Role for Mucin-5AC in Upper and Lower Airway Pathogenesis in Mice.

Mucin-5AC (MUC5AC) is a major secreted mucin in pathogenic airways. To determine its role in mucus-related airway disorders, -deficient () and wild-type () mice were compared in bleomycin-induced pulmonary fibrosis, respiratory syncytial virus (RSV) disease, and ozone toxicity. Significantly greater inflammation and fibrosis by bleomycin were developed in lungs compared to lungs.

THERPA: A small molecule database related to prion protein regulation and prion diseases progression.

Prion diseases are fatal neurodegenerative disorders that affect humans and animals. Although various small molecules have been evaluated for application in the treatment of prion diseases, none have been shown to be efficacious. Expanding our knowledge of these molecules is important for understanding of the complex mechanisms of prion diseases.

Dietary Calcium Intake May Contribute to the HOMA-IR Score in Korean Females with Vitamin D Deficiency (2008-2012 Korea National Health and Nutrition Examination Survey).

Background: Vitamin D and calcium are important factors involved in the regulation of blood glucose and insulin secretion. The Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) score is a useful variable for evaluating insulin resistance, and therefore we cross-sectionally compared HOMA-IR scores according to serum vitamin D levels and dietary calcium intake.

Methods: We selected data from healthy males (n=5,163) and females (n=7,506) analyzed over 5 years (2008-2012) via the Korea National Health and Nutrition Examination Survey (KNHANES).

Color Doppler Sonography Accompanied by Dynamic Scanning for the Diagnosis of Ankle and Foot Fractures.

Sonography is conventionally used to diagnose fractures by identifying cortical discontinuity of the bone. In this study, fracture sonography in addition to color Doppler and dynamic scanning was performed in settings with limited or no access to radiography. We describe 5 cases of ankle and foot fractures with the use of sonography to identify changes in the fractured site.

The Cut-off Value of Blood Mercury Concentration in Relation to Insulin Resistance.

Background: Increased blood mercury concentration is associated with inflammation, and chronic inflammation can cause insulin resistance. We examined the cut-off value of blood mercury in relation to an increased score on the homeostasis model assessment for insulin resistance (HOMA-IR).

Methods: We used data from the Korean National Health and Nutrition Examination Survey (2008-2010).

Coronary Calcification Is Reversely Related with Bone and Hair Calcium: The Relationship among Different Calcium Pools in Body.

Background: With aging, calcium efflux from bone is increased with age-related bone loss, and it can reduce bone mineral density (BMD). On the contrary, age-related calcium adoption into arterial wall progressively stiffens blood vessels. Theses process insinuates shift of calcium among different pools in body.

Allergen-Removed Rhus verniciflua Extract Induces Ovarian Cancer Cell Death via JNK Activation.

Nuclear factor-[Formula: see text]B (NF-[Formula: see text]B)/Rel transcription factors are best known for their central roles in promoting cell survival in cancer. NF-[Formula: see text]B antagonizes tumor necrosis factor (TNF)-[Formula: see text]-induced apoptosis through a process involving attenuation of the c-Jun-N-terminal kinase (JNK). However, the role of JNK activation in apoptosis induced by negative regulation of NF-[Formula: see text]B is not completely understood.

Genome-wide association study of metabolic syndrome in koreans.

Metabolic syndrome (METS) is a disorder of energy utilization and storage and increases the risk of developing cardiovascular disease and diabetes. To identify the genetic risk factors of METS, we carried out a genome-wide association study (GWAS) for 2,657 cases and 5,917 controls in Korean populations. As a result, we could identify 2 single nucleotide polymorphisms (SNPs) with genome-wide significance level p-values (<5 × 10(-8)), 8 SNPs with genome-wide suggestive p-values (5 × 10(-8) ≤ p < 1 × 10(-5)), and 2 SNPs of more functional variants with borderline p-values (5 × 10(-5) ≤ p < 1 × 10(-4)).

Blood mercury can be a factor of elevated serum ferritin: analysis of Korea National Health and Nutrition Examination Survey (KNHANES 2008-2012).

Serum ferritin as well as blood mercury are reported to be associated with chronic inflammation. However, the relation between serum ferritin and blood mercury has not yet been established. We utilized the Korea National Health and Nutrition Examination Survey (KNHANES, 2008-2012) 10,977 subjects (5433 males and 5544 females).
