Pharmacogenomics can explain the inter-individual differences in response to drugs, including methotrexate (MTX) used for acute graft-versus-host disease (aGVHD) prophylaxis during hematopoietic stem cell transplantation (HSCT). In real-world practice, preplanned MTX dose is arbitrarily modified according to observed toxicity which can lead to unexpected and severe aGVHD development. We aimed to validate the influence of MTHFR C677T polymorphism on the outcomes of allogenic HSCT in a relatively under-represented homogenous Asian population...

Organic-inorganic hybrid perovskite solar cells have emerged as promising candidates for next generation solar cells. To attain high photovoltaic efficiency, reducing the defects in perovskites is crucial along with a uniform coating of the films. Also, evaluating the quality of synthesized perovskites via facile and adequate methods is important as well. Herein, CH3NH3PbI3 perovskites were synthesized by applying second solvent dripping to non-stoichiometric precursors containing excess CH3NH3I. The resulting perovskite films exhibited a larger average grain size with a better crystallinity compared to that from stoichiometric precursors...

Non-umbilical cutaneous metastases from pancreatic adenocarcinomas are extremely rare. Only a few cases have been reported in the literature. An 83-year-old Korean woman, with no previous medical history, presented with a painful nodule on her scalp. Histologic examination of the nodule revealed a metastatic adenocarcinoma, and immunohistochemical staining was positive for cytokeratin (CK) 7 and CK 19. These findings were consistent with a metastatic carcinoma of pancreatic origin. An abdominal computed tomography scan identified a mass on the pancreatic head and multiple enlarged lymph nodes...

Background/Aims: Several studies suggest that pyogenic liver abscess (PLA) is associated with colon neoplasm. A colonoscopic exam for cryptogenic PLA might detect a hidden colon neoplasm, through which intestinal flora can be transmitted into the liver. However, there are no prospectively enrolled cross-sectional data for colonic neoplasm in cryptogenic PLA. Methods: Patients with PLA were prospectively enrolled from two university hospitals. Among them, all the patients with cryptogenic PLA were recommended for colonoscopic exam to check for colonic neoplasm...

Severe hepatic inflammation is a common cause of acute or chronic liver disease. Macrophages are one of the key mediators which regulate the progress of hepatic inflammation. Increasing evidence shows that the TAM (TYRO3, AXL and MERTK) family of RTKs (receptor tyrosine kinases), which is expressed in macrophages, alleviates inflammatory responses through a negative feedback loop. However, the functional contribution of each TAM family member to the progression of hepatic inflammation remains elusive. In this study, we explore the role of individual TAM family proteins during autophagy induction and evaluate their contribution to hepatic inflammation...

BACKGROUND: Gadoxetic acid is a liver-specific intravenous T1 magnetic resonance (MR) contrast agent that is excreted via the hepatobiliary system. We hypothesize that hepatocyte expressions of bile transporters (OATP1 and MRP2) correlate with dynamic profile of Gadoxetic acid enhanced (GE)-MR imaging (MRI). METHODS: Two groups of rats, control (n = 6) and cirrhosis (n = 12), received gadoxetic acid enhanced MRI followed by 70% hepatectomy. The change in MR signal intensity from the baseline before the contrast injection (ΔSI) was analyzed every minute for 30 min...

Endoplasmic reticulum (ER) stress is triggered by various cellular stresses that disturb protein folding or calcium homeostasis in the ER. To cope with these stresses, ER stress activates the unfolded protein response (UPR) pathway, but unresolved ER stress induces reactive oxygen species (ROS) accumulation leading to apoptotic cell death. However, the mechanisms that underlie protection from ER stress-induced cell death are not clearly defined. The nuclear factor erythroid 2-related factor 2 (Nrf2)-Kelch-like ECH-associated protein 1 (Keap1) pathway plays a crucial role in the protection of cells against ROS-mediated oxidative damage...

Laparoscopic inguinal hernia repair has been shown to have multiple advantages compared with open repair such as less postoperative pain and earlier resume of daily activities with a comparable recurrence rate. We speculate robotic inguinal hernia repair may yield equivalent benefits, while providing the surgeon added dexterity. One hundred consecutive robotic inguinal hernia repairs with mesh were performed with a mean age of 56 years (25-96). Fifty-six unilateral hernias and 22 bilateral hernias were repaired amongst 62 males and 16 females...

Stereotactic radiosurgery has been recognized as an effective treatment approach for metastatic brain tumors. By increasing the sensitivity of the tumor to radiation and decreasing the marginal dose, it is possible to improve therapeutic efficacy and decrease side-effects. In radiation-induced cells, c-Jun N-terminal kinase (JNK) signaling mediates the phosphorylation of H2AX, which indicates DNA damage sensitivity and modulates the effect of radiation. Lewis lung cancer (LLC) and breast cancer (4T1) cells were irradiated with a Gamma Knife in cell culture tubes...

We report the case of a 25-year-old woman presenting with left hip pain. A lesion was found in the proximal femoral metaphysis. Benign bone tumor, such as intraosseous lipoma or liposclerosing myxofibrous tumor, was suspected based on simple radiographs and magnetic resonance images. Curettage of the lesion and bone grafting was performed. Histologic findings reflected primary intraosseous xanthoma of the proximal femur. Laboratory tests revealed the patient to be normolipidemic, while immunoelectrophoretic fractionation of lipoproteins revealed normal values for alpha, pre-beta, beta, and chylomicrons...

Cystinosis is a rare disease characterized by abnormal lysosomal cystine accumulation of cystine due to impaired lysosomal transport. We previously reported the first case of cystinosis in Korea in a 12-year-old boy with short stature, general weakness, and photophobia. The diagnosis was confirmed based on ophthalmic findings and biochemical analyses (serum leukocyte cystine measurement). Major endocrine manifestations at diagnosis included hypothyroidism, growth retardation, and hypogonadism. Despite oral cysteamine administration and renal replacement therapy, multiple complications including both endocrine and nonendocrine disorders developed during and after adolescence...

Although we have recently demonstrated that carrageenan-induced inflammation upregulates the expression of spinal interleukin (IL)-1β, which inhibits spinal astrocyte activation and results in the delayed development of Mirror-Image Pain (MIP), little is known regarding the mechanisms that underlie how spinal IL-1β inhibits the astrocyte activation. In this study, we examined the effect of spinal IL-1β on astrocyte gap junctions (GJ) and the development of MIP. Following unilateral carrageenan (CA) injection, mechanical allodynia (MA) was evaluated at various time points...

A total of 23 PBDE congeners were measured in soil samples collected in areas with no known point source (urban/rural/background sites, U/R/B sites) and in contaminated areas (brominated flame retardants (BFRs) related industrial and e-waste recycling sites) across five Asian countries. The highest PBDE concentrations were found in BFRs related industrial and e-waste recycling sites. The concentrations of PBDEs in U/R/B sites followed the order of: urban > rural > background sites. Total PBDE concentrations were dominated by BDE-209, while BDE-17, -85, -138, -191, -204 and -205 were the least abundant compounds...

Globally, the incidence of communicable diseases has decreased compared to non-communicable diseases. However, chronic communicable diseases such as HIV/AIDS and tuberculosis persist worldwide. Furthermore, emerging new infections such as H1N1 influenza pose a new threat to public health. However, most studies have focused on non-communicable diseases because of their increasing incidence, with fewer studies investigating communicable diseases. Therefore, we estimated the burden of communicable diseases in Korea using national representative 2012 data...
