Relationships of physical and breast cancer phenotypes with three single-nucleotide polymorphisms (rs2046210, rs3757318, and rs3803662) associated with breast cancer risk in Japanese women.

Background: Recent genome-wide association studies have shown that many single-nucleotide polymorphisms (SNPs) are associated with breast cancer risk. However, it is often unclear how these SNPs are related to breast cancer. Analysis of associations between SNPs and phenotypes may be important for determining mechanisms of action, including carcinogenesis.

Influence of breast density on breast cancer risk: a case control study in Japanese women.

Background: Mammography is the standard examination for breast cancer screening of woman aged ≥ 40 years. High breast density on mammography indicates that mammary gland parenchyma occupy a high percentage of the breast. The objective of this study was to investigate factors associated with breast density and the risk of high breast density for breast cancer.

He received treatment; however, because his symptoms gradually worsened, he was transported to our hospital 10 days following his diagnosis.

Changes in the Expression of Circulating microRNAs in Systemic Lupus Erythematosus Patient Blood Plasma After Passing Through a Plasma Adsorption Membrane.

MicroRNAs (miRNAs, miRs) are small non-coding RNAs that mainly function in the post-transcriptional regulation of genes. miRNA that is secreted outside of cells, and which circulates in the peripheral blood, is called circulating microRNA. Systemic lupus erythematosus (SLE) is a typical autoimmune connective tissue disease and is mainly treated with immunosuppressive drugs.

Association of type II secretory phospholipase A and surfactant protein D with the pulmonary oxygenation potential in patients with septic shock during polymyxin-B immobilized fiber-direct hemoperfusion.

This study was undertaken to analyze the association of type II secretory phospholipase A (sPLA -II) and surfactant protein D (SP-D) with the pulmonary oxygenation potential in patients with septic shock during polymyxin-B immobilized fiber-direct hemoperfusion (PMX-DHP). The study was conducted in 25 patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). PMX-DHP lowered the blood endotoxin level in all patients.

Separation of Circulating MicroRNAs Using Apheresis in Patients With Systemic Lupus Erythematosus.

MicroRNAs (miRNAs), which are important inhibitors of mRNA translation, participate in differentiation, migration, cell proliferation, and cell death. The pathology of miRNAs results in alterations in protein expression. Recently, miRNAs circulating in peripheral blood have been shown to control the synthesis and translation of proteins at distal sites after intake into local cells.

N-acetyltransferase 2 polymorphism and breast cancer risk with smoking: a case control study in Japanese women.

Background: Recent studies have suggested that the association between smoking and breast cancer risk might be modified by polymorphisms in the N-acetyltransferase 2 gene (NAT2). Most of these studies were conducted in Western countries, with few reports from East Asia.

Methods: We conducted a case-control study of 511 breast cancer cases and 527 unmatched healthy controls from December 2010 to November 2011 in Japan.

Impact of modifiable lifestyle factors on outcomes after breast cancer diagnosis: the Setouchi Breast Cancer Cohort Study.

The primary purpose of this large cohort study is to investigate the effects on breast cancer outcomes of modifiable lifestyle factors after breast cancer diagnosis. These factors include physical activity, smoking, alcohol consumption, obesity and weight gain after diagnosis, alternative medicine and dietary factors.

Green Urine Discoloration due to Propofol Infusion: A Case Report.

We present a 19-year-old man who excreted green urine after propofol infusion. The patient was admitted to our hospital for injuries sustained in a traffic accident and underwent surgery. After starting continuous infusion of propofol for postoperative sedation, his urine became dark green.

Tumor inhibitory effect of gefitinib (ZD1839, Iressa) and taxane combination therapy in EGFR-overexpressing breast cancer cell lines (MCF7/ADR, MDA-MB-231).

Some kinds of breast cancer cell lines, similar to several types of solid tumors, express epidermal growth factor receptor (EGFR). However, gefitinib, an EGFR tyrosine kinase inhibitor, is not effective for all these cell lines. Similarly, taxane is effective for many of the cell lines, although some, such as the multidrug-resistant MCF7/ADR cell line, show taxane-resistance.

Mechanisms of protection by melatonin against acetaminophen-induced liver injury in mice.

The present study was performed to determine whether melatonin protects mouse liver against severe damage induced by acetaminophen (APAP) administration and where melatonin primarily functions in the metabolic pathway of APAP to protect mouse liver against APAP-induced injury. Treatment of mice with melatonin (50 or 100 mg/kg, p.o.

[Lung protection with anesthetics].

Common inhaled and intravenous anesthetics except the barbiturate are recommended for the patients with bronco-constrictive lung disease because of their bronco-dilating property. However there are pharmacological potency differences between individual anesthetics. The halogenated inhaled anesthetics and propofol exert antiinflammatory effect on acute lung injury and acute respiratory distress syndrome in the laboratory level, but further study is required for future clinical application.

Gefitinib, an epidermal growth factor receptor blockade agent, shows additional or synergistic effects on the radiosensitivity of esophageal cancer cells in vitro.

Human esophageal cancers have been shown to express high levels of epidermal growth factor receptor (EGFR) and a relationship between high EGFR expression and local advance, the number of lymph node metastases, life expectancy, and sensitivity to chemo-radiotherapy has been demonstrated. We examined the use of gefitinib, an orally active EGFR-selective tyrosine kinase inhibitor, as a new strategy for treatment of esophageal carcinoma. The effects of gefitinib were evaluated in monotherapy and in combination with radiotherapy in human esophageal carcinoma cell lines.

Clonidine premedication effects on inhaled induction with sevoflurane in adults: a prospective, double-blind, randomized study.

Background: The purpose of this study was to evaluate whether oral clonidine premedication becomes an alternative to N2O in terms of shortening the induction time and attenuation of the adrenergic response to tracheal intubation during inhalation induction with sevoflurane, and to evaluate the quality of anesthetic induction according to the patient's satisfaction.

Methods: We studied 84 female patients who were randomly allocated into four study groups: Groups I and II received a placebo orally, and Groups III and IV received clonidine at 150 and 300 microg, respectively, 90 min before induction of anaesthesia. Patients were anesthetized using a triple-deep-breath technique with 5% sevoflurane in Groups I, III and IV, and with 60% N2O-5% sevoflurane in group II.

Oral administration of geranylgeranylacetone improves survival rate in a rat endotoxin shock model: administration timing and heat shock protein 70 induction.

The present study was performed to determine whether oral pretreatment with geranylgeranylacetone (GGA) inhibits proinflammatory cytokine liberation and nitric oxide (NO) production in lipopolysaccharide (LPS)-treated rats and protects rats against death from LPS-induced endotoxin shock, and whether such protection by GGA is related to heat shock protein (HSP) 70 induction in multiple organs of rats. GGA (200 mg/kg) was given orally to rats. LPS (20 mg/kg) was administered intraperitoneally 4, 8, 16, or 24 h after GGA administration.

The presence of oxidized phosphatidylserine on Fas-mediated apoptotic cell surface.

A growing body of evidence suggests that phosphatidylserine (PS) oxidation is linked with its transmembrane migration from the inner to the outer leaflet of the plasma membrane during apoptosis. However, there is no direct evidence for the presence of oxidized PS (PSox) on the surface of cells undergoing apoptosis. The present study was performed to detect PSox externalized to the cell surface after Fas engagement in Jurkat cells.

Multidetector row computed tomography for diagnosing intraductal extension of breast carcinoma.

Objectives: Several reports supported the association of higher ipsilateral breast tumor recurrence rates with positive or intermediate margins compared with negative pathologic margins. Precise evaluation of intraductal component and adequate surgical margin are important factors affecting the tumor recurrence after breast conserving surgery. Numerous studies have reported the utility of magnetic resonance imaging for diagnosing developing intraductal extension of breast cancer, but few have investigated multidetector-row computed tomography (MD-CT).

Proteasome inhibitors can alter the signaling pathways and attenuate the P-glycoprotein-mediated multidrug resistance.

Numerous signaling pathways were reported to be involved in the resistance for conventional cytotoxic drugs, although one of the main reasons is the overexpression of P-glycoprotein (P-gp) in multidrug resistant cancer cells. The overexpression of P-gp has been associated with the resistance to a wide range of anticancer drugs. Doxorubicin and paclitaxel are substrates of this transporter system and have an important role for the various human malignancies.
