This prospective study evaluated the efficacy and toxicity of intravenous busulfan and melphalan as a conditioning regimen for autologous stem cell transplantation (ASCT) in patients with multiple myeloma (MM). A total of 99 patients with MM, enrolled between January 2013 and March 2016, received intravenous busulfan (9.6 mg/kg) and melphalan (140 mg/m2) prior to ASCT. The median time to transplant was 6.2 months, and 90 patients (90.9%) underwent ASCT within 12 months of the diagnosis. The overall response rate after ASCT was 94...

METHODS: We present a rare case with atypical presenting features of unilateral CPEO with a false positive Acetylcholine Receptor Antibody (AchRA) test resulting in diagnostic delay. We illustrate the unilateral nature of this case and demonstrate the caveats of performing myogenic ptosis correction in such patients. We also discuss the differential diagnosis of false positive AchRA, a test commonly performed in the investigation of ptosis. RESULTS: A 34-year old female presented with a more than 3-year history of slowly-progressive, unilateral, right-sided restriction in eye movements and ptosis...

The impact of residual electron correlation beyond the equation-of-motion coupled-cluster singles and doubles (EOM-CCSD) approximation on positions and widths of electronic resonances is investigated. To establish a method that accomplishes this task in an economical manner, several approaches proposed for the approximate treatment of triple excitations are reviewed with respect to their performance in the electron attachment (EA) variant of EOM-CC theory. The recently introduced EOM-CCSD(T)(a)* method [D. A...

BACKGROUND: Greater lymph node retrieval in gastric cancer improves staging accuracy and may improve survival from increased clearance of nodal micrometastasis. This retrospective cohort study investigated if more lymph nodes removed in gastric cancer increases survival and if such effect is stage-specific due to differential risks of nodal micrometastasis and systemic disease. METHODS: The prospectively collected database of curatively resected gastric cancer patients in National Cancer Center, South Korea between 2000 and 2009 was reviewed...

Elevated Bcl-xL expression in cancer cells contributes to DOX resistance, leading to failure in chemotherapy. In addition, the clinical use of high-dose doxorubicin (DOX) in cancer therapy has been limited by issues with cardiotoxicity and hepatotoxicity. Here, we show that co-treatment with pyrrolidine dithiocarbamate (PDTC) attenuates DOX-induced apoptosis in Chang-L liver cells and human hepatocytes, but overcomes DOX resistance in Bcl-xL-overexpressing Chang-L cells and several hepatocellular carcinoma (HCC) cell lines with high Bcl-xL expression...

Sumoylation, the conjugation of a small ubiquitin-like modifier (SUMO) protein to a target, has diverse cellular effects. However, the functional roles of the SUMO modification during myogenesis have not been fully elucidated. Here, we report that basal sumoylation of histone deacetylase 1 (HDAC1) enhances the deacetylation of MyoD in undifferentiated myoblasts, whereas further sumoylation of HDAC1 contributes to switching its binding partners from MyoD to Rb to induce myocyte differentiation. Differentiation in C2C12 skeletal myoblasts induced new immunoblot bands above HDAC1 that were gradually enhanced during differentiation...

Cyanobacterial bloom causes the release of algal organic matter (AOM), which inevitably affects the treatment processes of natural organic matter (NOM). This study works on treating micro-polluted surface water (SW) by emerging coagulant, namely titanium sulfate (Ti(SO4)2), followed by Low Pressure Ultrafiltration (LPUF) technology. In particular, we explored the respective influence of extracellular organic matter (EOM) and intracellular organic matter (IOM) on synergetic EOM-NOM/IOM-NOM removal, functional mechanisms and subsequent filtration performance...

PURPOSE: Studies of cytotoxic T cells and their respective lineage master regulators have been limited in Hashimoto's thyroiditis (HT). It is unclear whether their transcriptomes are changed in HT patients and how these changes are associated with the thyroid damage, major clinical manifestations, and disease progression. METHODS: We explored the gene expression patterns of selected transcription factors [eomesodermin (EOMES), BACH2, BCL6, TCF1] and cytolytic molecules [granzyme B (GZMB)] in peripheral blood (PB) T cells of 10 healthy controls and 30 HT patients of various subtypes (hypothyroid, untreated HT; L-thyroxine (T4)-treated HT, and spontaneously euthyroid HT) using real-time quantitative PCR...

PURPOSE: Diplopia is a common symptom of blowout fracture (BOF), and can persist after proper surgical management. We compared clinicoradiological findings between patients with recovering diplopia and those with residual diplopia after surgery for orbital BOF. MATERIALS AND METHODS: We retrospectively evaluated the CT images of 170 patients with orbital BOF and preoperative diplopia. We reviewed the following factors: sex, age, mechanism of injury, presence of diplopia before surgery, presence of enophthalmos before surgery, presence of an ocular motility abnormality before surgery, time interval between the trauma and surgery, fracture type, fracture size, volume of herniated orbital soft tissue, ratio of the volume of herniated orbital soft tissue to fracture size, number of points of contact between the extraocular muscle (EOM) and bony edge, EOM swelling, EOM swelling ratio, EOM displacement, EOM circling, EOM tenting, and EOM entrapment...

In a previous work, we reported the regulatory role of the triterpenoids on 5-hydroxytryptamine (5-HT)3A receptors activity in Xenopus laevis oocytes (Eur. J. Pharmacol., 615, 2009, Lee et al.). In the present report, we studied the modulation of triterpenoids on the activity of the human nicotinic acetylcholine receptor type α3β4. Two-electrode voltage clamp experiments were used to test acetylcholine mediated inward current (IACh). Treatment with triterpenoids (dehydroeburicoic acid, 6α-hydroxypolyporenic acid C and pachymic acid) inhibited IACh in a concentration dependent and reversible manner...

Evidence has shown that multidisciplinary tumor board conferences (MTBCs) improve patient management for various cancer types. However, few retrospective studies have investigated MTBC efficacy for patients with gynecologic cancers. Here, we prospectively aimed to evaluate how MTBCs influence patient management in gynecologic oncology. This prospective study included 85 consecutive cases that were presented at gynecologic oncology MTBCs in our tertiary university hospital between January 2015 and April 2016...

Here, we report thyroid transcription factor 1 (TTF-1) as an important transcription factor for the expression of heme oxygenase-1 (HO-1). HO-1 is a well-known cytoprotective enzyme against inflammation. We observed that HO-1 co-expressed with TTF-1 in mouse hypothalamic cells. Results from luciferase and chromatin immunoprecipitation assays revealed that TTF-1 directly activated HO-1 transcription by binding to binding domains in the 5'-flanking region of the HO-1 gene. A proinflammatory cytokine, tumor necrosis factor-alpha (TNF-α), induced nuclear translocation of TTF-1 and increased binding affinity of TTF-1 to its binding sites on the HO-1 gene...

Agonists to the TNF/TNFR costimulatory receptors CD134 (OX40) and CD137 (4-1BB) elicit antitumor immunity. Dual costimulation with anti-CD134 plus anti-CD137 is particularly potent because it programs cytotoxic potential in CD8+ and CD4+ T cells. Cytotoxicity in dual-costimulated CD4 T cells depends on the T-box transcription factor eomesodermin (Eomes), which we report is induced via a mechanism that does not rely on IL-2, in contrast to CD8+ CTL, but rather depends on the CD8 T cell lineage commitment transcription factor Runx3, which supports Eomes expression in mature CD8+ CTLs...

Background: The survival benefit of adjuvant radiotherapy (ART) in prostate adenocarcinoma, with limited numbers of pathologically involved lymph nodes (LNs) after radical prostatectomy (RP), is controversial. Materials and Methods: From 2004 to 2014, data for prostate cancer patients categorized as N1M0 after RP were retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. After propensity-score matching, the 10-year cancer-specific survival (CSS) rates between patients who received ART (ART group) or did not/unknown (no-ART group) were compared for each stratum of lymph node ratio (LNR) (%) according to the number of involved LNs...

The use of diffusion tensor imaging (DTI) for the characterization of various lesion types in dogs with spinal cord injury (SCI) has not been investigated. The purpose of this study was to characterize scarring [loose immature scarring (LIMS), intermediate mature scarring (IMS), and dense mature scarring (DMS)], necrosis, cavitation, and acute hemorrhage using multiple DTI parameters and determine the correlations between the DTI parameters and histopathological finding in dogs with controlled SCI. All imaging data were obtained from the lumbar spinal cord (from L1 to L3) of normal and SCI dogs using a 3-Tesla magnetic resonance imaging scanner...

The 1Lb and 1La excited states of naphthols are characterized by using time dependent density functional theory (TDDFT), configuration interaction with singles (CIS) and equation-of-motion coupled cluster singles and doubles (EOM-CCSD) methods. TDDFT fails dramatically at predicting the energy and ordering of the excited states 1La and 1Lb as observed experimentally while EOM-CCSD accurately predicts the excited states as characterized by the natural transition orbital (NTO) analysis. The limitations of TDDFT are traced back to the neglect of double excitations, essential for accurate descriptions of excited electronic states of naphthol photoacids...

Type 3 innate lymphoid cells (ILC3s) fulfill protective functions at mucosal surfaces via cytokine production. Although their plasticity to become ILC1s, the innate counterparts of type 1 helper T cells, has been described previously, we report that they can differentiate into cytotoxic lymphocytes with many characteristics of early differentiated natural killer (NK) cells. This transition is promoted by the proinflammatory cytokines interleukin 12 (IL-12) and IL-15, and correlates with expression of the master transcription factor of cytotoxicity, eomesodermin (Eomes)...

Ectopic breast tissue and male breast cancer are both very rare diseases with only a few reports in the literature. Here, we present the first case of ectopic male breast cancer in the perineum. The patient was a 70-year-old man with a palpable mass in the perineum. A wide local excision and inguinal lymph node dissection revealed invasive breast carcinoma of no special type involving the skin and subcutis, and inguinal lymph node metastases. Immunohistochemical staining showed that the tumor cells were strongly positive for estrogen and progesterone receptors and negative for human epidermal growth factor receptor 2...
