AIM: To investigate the abundance and potential functions of LAP(+)CD4(+) T cells in colorectal cancer (CRC). METHODS: Proportions of LAP(+)CD4(+) T cells were examined in peripheral blood and tumor/paratumor tissues of CRC patients and healthy controls using flow cytometry. Expression of phenotypic markers such as forkhead box (Fox)p3, cytotoxic T-lymphocyte-associated protein (CTLA)-4, chemokine CC receptor (CCR)4 and CCR5 was measured using flow cytometry. LAP(-)CD4(+) and LAP(+)CD4(+) T cells were isolated using a magnetic cell-sorting system and cell purity was analyzed by flow cytometry...

BACKGROUND: Right ventricular failure (RVF) complicates 9% to 44% of left ventricular assist device (LVAD) implants post-operatively. Current prediction scores perform only modestly in validation studies, and do not include immune markers. Chemokines are inflammatory signaling molecules with a fundamental role in cardiac physiology and stress adaptation. In this study we investigated chemokine receptor regulation in LVAD recipients who develop RVF. METHODS: Expression of chemokine receptor (CCR) genes 3 to 8 were examined in the peripheral blood of 111 LVAD patients, collected 24 hours before implant...

Anthropogenic activities resulting in releases of selenium-laden waste streams threaten freshwater ecosystems. Lake ecosystems demand special consideration because they are characterized by prolonged retention of selenium and continuous cycling of the element through the food chain, through which it becomes available to toxicologically susceptible egg-laying vertebrates. This study documents the current selenium burden of lakes in North Carolina (NC) with historic selenium inputs from nearby coal-fired power plants...

The FMS-like tyrosine kinase 3 (FLT3) mutation in acute myeloid leukemia (AML) is a negative prognostic factor and, in these cases, allogeneic stem cell transplantation (allo-SCT) can represent an important therapeutic option, especially if performed in complete remission (CR). However, it is increasingly clear that not all cytological CRs (cCRs) are the same and that minimal residual disease (MRD) before allo-SCT could have an impact on AML outcome. Unfortunately, FLT3, due its instability of expression, is still not considered a good molecular MRD marker...

Previous studies exploring the effects of attention-prioritization on cognitively healthy older adults' gait and cognitive dual task (DT) performance have shown DT cost in gait outcomes but inconsistent effects on cognitive performance, which may reflect task difficulty (the cognitive load). This study aimed to identify whether changing the cognitive load during a walking and counting DT improved the challenge/sensitivity of the cognitive task to observe prioritization effects on concurrent gait and cognitive performance outcomes...

: 296 Background: Breast and colon are 2 of the most prevalent cancers in California according to the California Cancer Registry (CCR). Health claims data contains a wealth of information on diagnoses and treatment but lacks clinical information critical for evaluating care. Registry data contains key clinical information, but often does not contain the complete treatment regimen. This project aims to assess the feasibility of linking commercial claims data to population-based cancer registry data, and to use the linked data to examine variation in quality measures at the regional and physician organization (PO) levels...

Treatment paradigms have changed rapidly for multiple myeloma, and immune therapies have taken center stage. Advances in therapies for myeloma have led to a dramatic improvement in the survival of patients with this incurable malignancy. The immune system is significantly impaired in patients with myeloma as a result of the disease leading to suppression of normal plasma cells as well the negative effects on cellular immunity. Given this scenario, immune approaches have not been successful until recently. Monoclonal antibodies directed against CD38 (daratumumab) and SLAMF7 (elotuzumab) are already in the clinic, and several other antibodies directed against different plasma cell antigens are under evaluation...

The pace of therapeutic drug development in multiple myeloma has reached unprecedented levels, with five regulatory approvals for relapsed and/or refractory disease of either new drugs or new drug regimens in 2015, one already in 2016, and still others anticipated. This has provided a wide array of options to be considered by patients and their health care providers in the event of relapse after or progression on front-line therapy. Most of these agents are currently being evaluated in earlier patient populations, including as parts of induction, consolidation, and maintenance therapy approaches, where their benefits may be even greater...

Multiple myeloma is a plasma cell malignancy characterized by molecular and clinical heterogeneity. The outcome of the disease has been dramatically improved with the advent of new drugs in the past few years. However, even in this context of increasing therapeutic options, important challenges remain, such as accurately evaluating patients' prognosis and predicting sensitivity to specific treatments and drug combinations. Transcriptomic studies have largely contributed to help decipher multiple myeloma complexity, characterizing multiple myeloma subgroups distinguished by different outcomes...

Over the past few years, the management of multiple myeloma has changed. We have new guidelines regarding how to set the diagnosis, when to initiate therapy, and how to monitor treatment response. In 2014, the updated International Myeloma Working Group (IMWG) diagnostic criteria changed the definition of multiple myeloma from being a disease defined by symptoms to a disease defined by biomarkers. Today, modern combination therapies have reported up to 60% to 80% of patients reaching a complete response. As a logical and necessary step forward, investigators have explored strategies to detect minimal residual disease (MRD) and its correlation with clinical outcomes...

Remarkable progress has been achieved in multiple myeloma, and patient median survival has been extended 3- to 4-fold. Specifically, there have been 18 newly approved treatments for multiple myeloma in the past 12 years, including seven in 2015, and the treatment paradigm and patient outcome have been transformed. The definition of patients benefitting from these therapies has been broadened. Response criteria now include minimal residual disease (MRD), assessed in bone marrow by multicolor flow cytometry or sequencing, and by imaging for extramedullary disease...

BACKGROUND AND AIM: There is clear association between knowledge on healthy lifestyle and intensity of healthy behaviours, especially among young people. We sought to verify this hypothesis among patients after acute coronary syndrome who were subjected to early in-hospital complex cardiac rehabilitation (CCR) by assessing relationship between initial knowledge on cardio-vascular risk factors and efficiency of rehabilitation. METHODS: 205 consecutive patients (153 man; age 62±9 years) hospitalized between 05...

Phosphorylated phosphoinositide lipids (PPIs) are low-abundance signaling molecules that control signal transduction pathways and are necessary for cellular homeostasis. The PPI phosphatidylinositol (3,5)-bisphosphate (PI(3,5)P2) is essential in multiple organ systems. PI(3,5)P2 is generated from PI3P by the conserved lipid kinase Fab1/PIKfyve. Defects in the dynamic regulation of PI(3,5)P2 are linked to human diseases. However, few mechanisms that regulate PI(3,5)P2 have been identified. Here we report an intramolecular interaction between the yeast Fab1 kinase region and an upstream conserved cysteine-rich (CCR) domain...

BACKGROUND AND OBJECTIVE: Acute eosinophilic pneumonia (AEP) is characterized by a massive pulmonary infiltration of eosinophils. Mechanisms regulating the selective accumulation of eosinophils in AEP have not been fully established. The objective of this study was to evaluate the mechanisms of eosinophil accumulation in alveolar spaces through examination of bronchoalveolar lavage fluid (BALF) from AEP patients (AEP-BALF). METHODS: Eosinophils were isolated from the blood of healthy subjects and were placed on a human pulmonary microvascular endothelial cell monolayer cultured on Transwell filters (Coster, Cambridge, MA, USA)...

The most frequent relapse site of gastrointestinal stromal tumors(GIST)is the liver. We encountered a patient with longterm survival treated with multidisciplinary treatment, including4 hepatectomies for liver metastases. The patient was a woman aged 69 years at the time of the first medical treatment. She underwent total gastrectomy and S6 segmental hepatec- tomy for a stomach GIST with a hepatic metastasis. The tumor diameter was 24 cm and the mitotic figure was 65/50 HPF. According to the guidelines, it was diagnosed as a high risk GIST based on strong positive immunostaining for CD34 and c-kit...

Previously it was shown that cryopreservation using an ice-free cryopreservation method with the cryoprotectant formulation VS83 beneficially modulated immune reactions in vivo and in vitro when compared with conventionally frozen tissues. In this study, we assessed the impact of a VS83 post-treatment of previously conventionally frozen human tissue on responses of human immune cells in vitro. Tissue punches of treated and non-treated (control) aortic heart valve tissue (leaflets and associated aortic root) were co-cultured for 7 days with peripheral blood mononuclear cells or enriched CD14(+) monocytes...

: Catabolite control protein A (CcpA) is the master regulator in Gram-positive bacteria that mediates carbon catabolite repression (CCR) and carbon catabolite activation (CCA), two fundamental regulatory mechanisms that enable competitive advantages in carbon catabolism. It is generally regarded that CcpA exerts its regulatory role by binding to a typical 14- to 16-nucleotide (nt) consensus site that is called a catabolite response element (cre) within the target regions. However, here we report a previously unknown noncanonical flexible architecture of the CcpA-binding site in solventogenic clostridia, providing new mechanistic insights into catabolite regulation...

Gentamicin (GNT) is an aminoglycoside antibiotic used for treatment of serious infections, and the nephrotoxic adverse effect is one of the main therapeutic limitations. This study aimed to investigate the possible protective effect of apocynin (APO) on nephrotoxicity induced by GNT in rats. Twenty-four rats were allocated into three groups: control, GNT (100 mg/kg, intraperitoneally (i.p.)), and GNT plus APO (10 mg/kg, i.p.). All rats were killed at the end of the experiment, and then the blood, urine, and kidneys samples were taken...
