Effects of voluntary exercise and electrical muscle stimulation on reaction time in the Go/No-Go task.

Introduction: Acute exercise improves cognitive performance. However, it remains unclear what triggers cognitive improvement. Electrical muscle stimulation (EMS) facilitates the examination of physiological changes derived from peripheral muscle contraction during exercise.

The neuromodulatory role of dopamine in improved reaction time by acute cardiovascular exercise.

Acute cardiovascular physical exercise improves cognitive performance, as evidenced by a reduction in reaction time (RT). However, the mechanistic understanding of how this occurs is elusive and has not been rigorously investigated in humans. Here, using positron emission tomography (PET) with [ C]raclopride, in a multi-experiment study we investigated whether acute exercise releases endogenous dopamine (DA) in the brain.

[Usefulness of Mohs Paste Against Breast Cancer with Skin Invasion].

We report with the addition of literature because we have experienced 3 cases of locally advanced breast cancer with skin invasion that have alleviated symptoms and improved quality of life by using Mohs paste. In Case 1, Mohs paste reduced exposed tumors, exudation, and bleeding. In Case 2, bleeding, which had been the cause of the marked anemia, was controlled, and tumor shrinkage and epithelialization were observed.

Systemic Lupus Erythematosus Presenting With Thrombotic Thrombocytopenic Purpura at Onset: A Case Report.

Background: Thrombotic microangiopathy (TMA) is a syndrome associated with hemolytic anemia, thrombocytopenia, and various organ disorders. Thrombotic thrombocytopenic purpura (TTP) is a disease that develops when a disintegrin-like and metalloproteinase with thrombospondin type l motif 13 (ADAMTS13) activity decreases to < 10% of that in normal plasma, causing platelet thrombosis in microvessels throughout the body. Currently, ADAMTS13-deficient TMA is diagnosed as TTP.

Effects of electrical muscle stimulation on cerebral blood flow.

Background: Electrical muscle stimulation (EMS) induces involuntary muscle contraction. Several studies have suggested that EMS has the potential to be an alternative method of voluntary exercise; however, its effects on cerebral blood flow (CBF) when applied to large lower limb muscles are poorly understood. Thus, the purpose of this study was to examine the effects of EMS on CBF, focusing on whether the effects differ between the internal carotid (ICA) and vertebral (VA) arteries.

Clinical characteristics of Campylobacter enteritis after pediatric renal transplantation: A retrospective analysis from single center.

Background: There are few reports of patients with Campylobacter enteritis after renal transplantation, and only a few case reports of bacteremia have been published. Although antibiotic therapy for 3-5 days has been recommended for immunocompromised patients, the optimal treatment for Campylobacter enteritis after renal transplantation has not been established. This study aimed to clarify the clinical characteristics and treatment outcomes of Campylobacter enteritis after pediatric renal transplantation.

P21-activated kinase 5 (PAK5), also termed PAK7, is one of the six members of the PAK family of serine/threonine kinases, which are downstream effectors in several cancer signaling pathways. PAK5 promotes neural outgrowth, contributes to microtubule stability and induces resistance to apoptosis. However, the clinical importance of PAK5 in gastric cancer has not been comprehensively investigated.

Background: As the major subfamily of receptor tyrosine, erythropoietin-producing hepatocellular (Eph) receptor has been related to progression and prognosis in different types of tumors. However, the role and mechanism of EPHA3 in gastric cancer is still not well understood.

Methods: Specimen were collected from 202 patients who underwent gastric resection for gastric adenocarcinoma.

TPX2 expression is associated with poor survival in gastric cancer.

Background: Targeting protein for Xenopus kinesin-like protein 2 (TPX2) is a microtubule-associated protein required for microtubule formation in human cells. Several studies have demonstrated that TPX2 is overexpressed in multiple tumor types and promotes tumor growth and metastasis. However, there have been few reports regarding its role in gastric cancer.

Cadherin 5 expression correlates with poor survival in human gastric cancer.

Aims: Although expressed in tumour cells of various malignancies, cadherin 5 (CDH5), also known as vascular endothelial cadherin, plays an important role in homotypic cell-cell adhesion among epithelial cells. However, the clinical significance of CDH5 expression in gastric cancer has not been sufficiently demonstrated. In this study, CDH5 expression in gastric cancer was evaluated and the correlations between CDH5 expression and the clinicopathological features and outcomes of the disease were examined.

Clinical significance of platelet derived growth factor-C and -D in gastric cancer.

Platelet-derived growth factor (PDGF)-C and PDGF-D are frequently upregulated in human cancers and play important roles in tumor progression, angiogenesis and metastasis. However, the distribution, frequency and prognostic value of PDGF-C and PDGF-D expression in gastric cancer have not been clarified. The present study evaluated the association between expression of PDGF-C and PDGF-D, clinicopathological factors and outcomes, in patients with gastric cancer.

Prognostic significance of PAK4 expression in gastric cancer.

Aims: p-21 activated kinase (PAK) 4, part of the six PAK families, plays an important role in growth factor signalling, cytoskeletal remodelling, gene transcription, cell proliferation and oncogenic transformation.

Miniaturized antibodies for imaging membrane type-1 matrix metalloproteinase in cancers.

Since membrane type-1 matrix metalloproteinase (MT1-MMP) plays pivotal roles in tumor progression and metastasis and holds great promise as an early biomarker for malignant tumors, a method of evaluating MT1-MMP expression levels would be valuable for molecular biological and clinical studies. Although we have previously developed a (99m) Tc-labeled anti-MT1-MMP monoclonal IgG ((99m) Tc-MT1-mAb) as an MT1-MMP imaging probe by nuclear medical techniques for this purpose, slow pharmacokinetics were a problem due to its large molecular size. Thus, in this study, our aim was to develop miniaturized antibodies, a single chain antibody fragment (MT1-scFv) and a dimer of two molecules of scFv (MT1-diabody), as the basic structures of MT1-MMP imaging probes followed by in vitro and in vivo evaluation with an (111) In radiolabel.

Prognostic value of RKIP and p-ERK in gastric cancer.

Background: The mitogen-activated protein kinase (MAPK) signaling pathway participates in several steps of tumour development and is considered a prominent therapeutic target for the design of chemotherapeutic agents. We evaluated the expressions of extracellular signal-regulated kinase (ERK), mitogen-activated protein kinase (MEK), an upstream regulator of ERK, and Raf kinase inhibitor protein (RKIP), and investigated correlations of these expressions with clinicopathological features and outcomes in gastric cancer.

Prognostic value of co-expression of STAT3, mTOR and EGFR in gastric cancer.

Signal transducer and activator of transcription 3 (STAT3), the mammalian target of rapamycin (mTOR) and epidermal growth factor receptor (EGFR), proteins that mediate intracellular signaling related to cell growth, proliferation and differentiation, have received considerable interest as possible targets for cancer treatment. We examined whether the expression of STAT3, mTOR and EGFR correlates with clinicopathological features and patient outcome in gastric cancer. Tumor samples were obtained from 126 patients with gastric adenocarcinomas who underwent a radical gastrectomy between 1999 and 2002.
