The strong expression of Oct4 and Nanog in metaplastic ducts and Oct4 expression preceding Ras mutation suggests that these homeobox transcription factors are associated with the early stage of pancreatic cancer carcinogenesis and may play an important role in that process.

Staphylococcus aureus is a leading cause of bacteremia in hospitalized patients. Whether or not S. aureus bacteremia (SAB) is associated with clonality, implicating potential nosocomial transmission, has not, however, been investigated. Herein, we examined the epidemiology of SAB using whole genome sequencing (WGS). 152 SAB isolates collected over the course of 2015 at a single large Minnesota medical center were studied. Staphylococcus protein A (spa) typing was performed by PCR/Sanger sequenci

INTRODUCTION: In this study, we determined whether serum ferritin levels could be used to differentiate between fever of unknown origin (FUO) caused by infectious and noninfectious diseases. METHODS: FUO patients were hospitalized at Chonnam National University Hospital between January, 2005 and December, 2011. According to the final diagnoses, five causes were identified, including infectious diseases, hematologic diseases, noninfectious inflammatory diseases, miscellaneous and undiagnosed. RES

Reports on the clinical entity of hemorrhagic fever with renal syndrome (HFRS) have focused on acute renal failure. Data on the extrarenal manifestations are limited primarily to case reports. In this study, protean extrarenal manifestations involving the major organs occurred in one-third of patients with HFRS during various stages (i.e., febrile phase through diuretic phase). Pancreatobiliary manifestations and major bleeding occurred in 11% and 10% of patients, respectively. Cardiovascular an

Hemophagocytic lymphohistiocytosis (HLH) has been described in patients with advanced stages of human immunodeficiency virus (HIV) infection, but rarely occurs during the seroconversion stage of acute HIV infection. We report a case of acute HIV syndrome that presented with virus-associated HLH. The patient recovered spontaneously without any immunomodulating therapy. This case suggests that acute HIV infection should be included in the differential diagnosis of HLH and indicates that HLH associ

ABSTRACT We developed a rat model of methicillin-resistant Staphylococcus epidermidis (MRSE) foreign body-associated osteomyelitis and used it to compare tedizolid alone and in combination with rifampin against rifampin alone, vancomycin plus rifampin, and vancomycin alone. A clinical strain of MRSE was inoculated into the proximal tibia, and a stainless steel wire with a precolonized MRSE biofilm was implanted. Following a 1-week infection period, 92 rats received either no treatment ( n = 17)

BACKGROUND: High rates of antimicrobial resistance in Escherichia coli isolated from patients with urinary tract infections have been reported worldwide. The aim of this study was to identify risk factors for resistance to ciprofloxacin (CIP) and cefotaxime (CTX) in E. coli isolated from patients with acute pyelonephritis (APN). METHODS: We prospectively identified women over 18 y of age who visited the emergency department of one of 10 hospitals with APN and whose urine culture grew E. coli. Th

Our data suggest that the outcome of TGC plus ciprofloxacin therapy was comparable to that of TGC plus doxycycline therapy in patients with V. vulnificus septicemia.

BACKGROUND: Hepcidin, a key regulator of iron homeostasis, is also a marker of acute inflammation. In the present study we investigated the changes in the serum hepcidin level and correlations between hepcidin and other markers of acute inflammation during the perioperative period in patients after abdominal surgery. METHODS: Serum hepcidin, hemoglobin (Hb), hematocrit (Ht), white blood cell (WBC) count, frequency of neutrophils, and C-reactive protein (CRP) were measured preoperatively (Pre), a

Rifamycins other than rifampicin show promising antistaphylococcal activity, including antibiofilm activity. Rifamycin-resistant staphylococci exhibit rpoB gene mutations.

Extracellular vesicle-derived microRNAs (EV-miRNAs) are promising biomarkers for early cancer diagnosis. However, existing EV-miRNA extraction technologies have a complex two-step process that results in low extraction efficiency and inconsistent results. This study aimed to develop and evaluate a new single-step extraction method, called miRQuick, for efficient and high-recovery extraction of EV-miRNAs from samples. The miRQuick method involves adding positively charged substances to the sample

남한의 수 개 지역에서 채집한 3과 8종의 톡토기 가운데 6종 (Oudemansia esakii (Kinoshita, 1932), Axelsonia littoralis (Moniez. 1890), Sinella (S. str.) straminea (Folsom. 1899), Sinella (S. str.) coeca (Schott, 1899), Entomobrya marginata (Tullberg, 1871), Willowsia bimaculata (Borner, 1909))이 한국 미기록종으로 판명되어 보고한다. 이 중 Oudemansia esakii, Axelsonia littoralis와 Entomobrya marginata 3종은 호염성이고, Sinella straminea와 Sinella coeca는 개미집에서 채집되었다. Sinella속의 2종은 한반도에서 개미집으로부터 채집된 톡토기의 첫 보고이다. 본 조사 결과 한국산 톡토기는 모두 10과 204종에 이른다. 【Thi
