PURPOSE: Interaction between immune-regulatory proteins and tumor infiltrating lymphocytes (TILs) is complex, and their associations may have significant clinical implications. This study was designed to evaluate the relationships between immunomodulatory proteins and TIL subsets and their impact on prognosis in breast cancer. METHODS: 377 invasive breast cancer cases were selected, and immunohistochemistry was performed for HLA-A, HLA-ABC, and indoleamine 2,3-dioxygenase (IDO); CD4+, CD8+, and FOXP3+ T cells were counted in intratumoral and stromal areas for both absolute numbers as well as their ratios...

We developed a system for the remote frequency comparison of optical clocks. The system does not require a flywheel oscillator at the remote end, making it possible to evaluate optical frequencies even in laboratories, where no stable microwave reference, such as an Rb clock, a Cs clock, or a hydrogen maser exists. The system is established by the integration of several systems: a portable carrier-phase two-way satellite frequency transfer station and a microwave signal generation system by an optical frequency comb from an optical clock...

The intestinal microbiota undergoes diurnal compositional and functional oscillations that affect metabolic homeostasis, but the mechanisms by which the rhythmic microbiota influences host circadian activity remain elusive. Using integrated multi-omics and imaging approaches, we demonstrate that the gut microbiota features oscillating biogeographical localization and metabolome patterns that determine the rhythmic exposure of the intestinal epithelium to different bacterial species and their metabolites over the course of a day...

Two-dimensional spatial profiles of potential fluctuation were measured with the heavy ion beam probe (HIBP) in the Large Helical Device (LHD). For 2D spatial profile measurements, the probe beam energy has to be changed, which requires the adjustment of many deflectors in the beam transport line to optimize the beam trajectory, since the transport line of LHD-HIBP system is long. The automatic beam adjustment system was developed, which allows us to adjust the beam trajectory easily. By analyzing coherence between potential fluctuation and magnetic probe signal, the noise level of the mode power spectrum of the potential fluctuation can be reduced...

BACKGROUND: Ayurved Siriraj Wattana recipe (AVS073), has been prescribed as tonic, to increase appetite, and for pain relief. It also exhibits antioxidant, anti-inflammatory, immunomodulating and anti-cancer activities. However, the immunomodulatory effects on antigen-presenting cells and effector T cells remained elusive. We thus aimed to study the effects of AVS073 on differentiation, maturation, functions and proportions of CIK cells and monocyte-derived DCs. METHODS: CIK cells and monocyte-derived DCs were treated with AVS073, followed by the assessment of T-helper (Th) phenotypes using real-time RT-PCR and flow cytometry...

Introduction Anastomotic leak (AL) after colorectal surgery is a devastating complication; decreased blood perfusion is an important risk factor. Surgeons rely on subjective measures to assess bowel perfusion. Fluorescence imaging (FI) with indocyanine green (ICG) provides a real-time objective assessment of intestinal perfusion. Areas Covered A Pubmed search using the terms 'fluorescence imaging', 'indocyanine green', 'colon and rectal surgery' was undertaken. Sixteen articles between 2010 to present were identified...

BACKGROUND: Diabetes mellitus is associated with an increased risk of recurrence in patients with ovarian cancer. Retrospective studies suggested that the use of statins, metformin and beta blockers is associated with improved prognosis in these patients. Patients with diabetes often suffer from hypertension and are usually treated concomitantly by several classes of drugs. Our aim was to assess the independent contribution of diabetes mellitus and hypertension and of the use of aspirin, statins, metformin and beta blockers on the risk of ovarian cancer recurrence and mortality...

Infection of the encephalomyocarditis virus (EMCV) in mice is an established model for viral myocarditis. Previously, we have demonstrated that indoleamine 2,3-dioxygenase (IDO), an L-tryptophan - kynurenine pathway (KP) enzyme, affects acute viral myocarditis. However, the roles of KP metabolites in EMCV infection remain unclear. Kynurenine 3-monooxygenase (KMO) is one of the key regulatory enzymes, which metabolizes kynurenine to 3-hydroxykynurenine in the KP. Therefore, we examined the role of KMO in acute viral infection by comparing between KMO(-/-) mice and KMO(+/+) mice...

Pulmonary embolism (PE) is a major cause of morbidity and mortality world-wide, and the use of thrombolytic therapy has been associated with favourable clinical outcomes in certain patient subsets. These potential benefits are counterbalanced by the risk of bleeding complications, the most devastating of which is intracranial haemorrhage (ICH). We retrospectively evaluated 9703 patients from the 2003-2012 nationwide in-patient sample database (NIS) who received thrombolytics for PE. All patients with ICH during the PE hospitalisation were identified and a clinical risk score model was developed utilizing demographics and comorbidities...

Mesenchymal stem cells (MSC) from rodents and humans have been shown to suppress T cells by distinct primary pathways, with NO-dependent pathways dominating in rodents and IDO-dependent pathways dominating in humans. However, the immune suppressive pathways utilized by canine MSC have not been as thoroughly studied, nor have BM-MSC and Ad-MSC been directly compared for their immune modulatory potency or pathway utilization. Therefore, canine BM-MSC and Ad-MSC were generated in vitro and their potency in suppressing T cell proliferation and cytokine production was compared, as well as differential gene expression...

: One of the major design considerations for a drug is its pharmacokinetics in the blood. A drug with short half-life in the blood is less available at a target organ. Such a limitation dictates treatment with either high doses or more frequent doses, both of which may increase the likelihood of undesirable side effects. To address the need for additional methods to improve the blood half-life of drugs and molecular imaging agents, we developed an "add-on" molecule that contains three groups: (i) truncated Evans Blue (EB) dye molecule that binds to albumin with low micromolar affinity and provides prolonged half-life in the blood; (ii) a metal chelate that allows radiolabeling for imaging and radiotherapy; and (iii) a maleimide for easy conjugation to drug molecules...

Increased adipocyte size is hypothesized to signal the recruitment of adipose progenitor cells (APCs) to expand tissue storage capacity. To investigate depot- and sex-differences in adipose growth, male and female C57BL/6J mice (10-weeks-old) were challenged with high fat (HF) or low fat (LF) diets (D) for 14 weeks. The HFD increased gonadal (GON) depot weight by adipocyte hypertrophy and hyperplasia in females, but hypertrophy alone in males. In both sexes, inguinal (ING) adipocytes were smaller than GON and depot expansion was due to hypertrophy...

B7 costimulatory molecules are present on antigen-presenting cells (APCs) and influence intracellular expression of indoleamine 2,3-dioxygenase (IDO), a molecule with important immunoregulatory functions. We determined the frequency of activated (CD11b+) monocytes expressing B7-1, B7-2, B7-H1, and B7-H2 molecules, and that of CD3+ and CD4+ T cells expressing the corresponding CD28, CTLA-4, PD-1, and ICOS receptors in peripheral blood samples of 20 healthy adults and 9 SSc and 15 pSS patients using flow cytometry...

Compelling evidence supports the involvement of the pro-inflammatory cytokines, IL-6, IFN-α and TNF-α in depression and related stress-associated pathologies. A role has also been suggested for the Th1-type cytokine, IFN-γ, with most mechanistic accounts focusing on the cytokine's capacity to induce indoleamine 2,3-dioxygenase (IDO), leading to diminished tryptophan and the generation of kynurenine metabolites. Beyond these IDO-dependent routes, there is surprisingly little evidence directly linking IFN-γ to alterations of brain regional monoamine activity and HPA axis functioning...

Monoamine oxidases (MAO), downstream targets of glucocorticoid, maintain the turnover and homeostasis of monoamine neurotransmitters; yet, its pathophysiological role in monoamine deficiency, oxidative stress and neuroinflammation remains controversial. Protective effects of M30, a brain selective MAO inhibitor with iron-chelating antioxidant properties, have been shown in models of neurodegenerative diseases. This study aims to examine the neuroprotective mechanism of M30 against depressive-like behavior induced by corticosterone (CORT)...
