OBJECTIVE: Being an African American man is a risk factor for prostate cancer and there is little consensus about the utility of screening, early detection, and the efficacy of treatment for the disease. In this context, this systematic review examines the roles women, particularly wives, play in African American men's prostate cancer screening and treatment decision-making. METHODS: We searched OVID Medline (R), CINAHL (EBSCO), PsychInfo (EBSCO), PubMED, Cochrane Library, ERIC (Firstsearch) and Web of Science to identify peer-review articles published between 1980-2016 that reported qualitative data about prostate cancer screening, diagnosis, or treatment in African American men...

Lifespan in poikilothermic organisms, such as Caenorhabditis elegans, can be substantially increased simply by decreasing growth temperature. To gain insights into the mechanistic underpinnings of this effect, we investigated the effects of temperature in development and adulthood on C. elegans lifespan. We found that worms exposed to 25°C during development and shifted to 15°C in adulthood exhibited an even longer lifespan than animals constantly kept at 15°C. Analysis of the in vivo redox status demonstrated that at 25°C, C...

BACKGROUND AND AIMS: Gambling disorder (GD) and alcohol use disorder (AD) have similar features, such as elevated impulsivity and decision-making deficits, which are directly linked to relapse and poor therapeutic outcomes. Our aim was to assess decision-making characteristics in GD and AD patients compared to healthy controls (HC) based on one of the most frequently used measures of decision-making: the Iowa Gambling Task (IGT). METHODS: In our systematic literature search of three databases, we identified 1198 empirical articles that mentioned decision-making deficits with the use of the IGT in patients diagnosed with either AD or GD...

BACKGROUND: Stress-induced failed resilience of brain plasticity can contribute to the onset and recurrence of depression. Chronic stress has been reported to open windows of epigenetic plasticity in hippocampus. However, how hippocampal plasticity underlies depression-like behaviors and how it adapts in response to stress has not been addressed. The present study aimed to investigate the signaling mechanisms of CUMS affecting hippocampal plasticity-related proteins expression and the regulation of swimming exercise in mice...

Anhedonia is an important feature of major depression and schizophrenia-spectrum disorders. Few neuroimaging studies have investigated neural alterations in high anhedonia, isolated from other psychopathological variables, by including only participants without clinical diagnoses. The present study examined healthy individuals scoring high (N = 18) vs. low (N = 19) in social anhedonia, who were carefully selected from a sample of N = 282 participants. To examine differences in automatic brain responses to social-affective stimuli between high vs...

The theoretical and practical application of Boykin and Schoenhofer's Nursing as Caring: A Model for Transforming Practice (2001) provided a framework for the exploration of an aesthetic project of quilting, which was undertaken in order to explain the death journey for a cherished mentor of American Indian nursing students. In particular, the nursing situation was used to guide the making of the quilt sampler. Aesthetics nested into the teaching-learning process became another way to help students solidify their professional self-identity as caring persons...

Mobilized peripheral blood (MPB) CD34+ cells were differentiated to CD34(+)/CD41(+) megakaryoblasts. Cells were sorted to obtain a pure megakaryoblast population which was reprogrammed with a hOKSM self-silencing polycistronic lentiviral vector. Resulting iPSC showed normal karyotype and expression of pluripotency associated markers and in vitro spontaneous differentiation towards the 3 germ layers confirmed pluripotency of iPSC lines. Besides normal iPSC applications, these lines can be used as a control line for other megakaryoid origin iPSC and could be applied for epigenetic based research...

Autosomal dominant polycystic kidney disease (ADPKD) is one of the most commonly inherited forms of polycystic kidney disease, and is characterized by the growth of numerous cysts in both kidneys. Here we generated an induced pluripotent stem cell (iPSC) line from the peripheral blood mononuclear cells (PBMCs) of a 63-year-old female ADPKD patient carrying an R803X mutation in the PKD2 gene using the Sendai-virus delivery system. Downstream characterization of these iPSCs showed that they possessed normal karyotyping, were free of genomic integration, retained the disease-causing PKD2 mutation, expressed pluripotency markers and could differentiate into three germ layers...

Peripheral blood mononuclear cells were isolated from an individual harboring a heterozygous c.859C→T p.Q287* mutation in GFI1B, causing an autosomal dominant bleeding disorder, platelet type, 17 (BDPLT17). PBMCs were differentiated to erythroblasts and reprogrammed by lentiviral delivery of a self-silencing hOKSM polycistronic vector. Pluripotency of iPSC line was confirmed by expression of associated markers and by in vitro spontaneous differentiation towards the 3 germ layers. Normal karyotype confirmed the genomic integrity of iPSCs and the presence of disease causing mutation was shown by Sanger sequencing...

High levels of CD25, as part of the IL-2 receptor, are expressed on the surface of the activated T lymphocytes and regulatory T cells, indicating that the soluble CD25 (sCD25) could be a clinically valuable tool for treating several diseases. Moreover, progress has been achieved in targeting the IL-2 receptor to treat autoimmune diseases, organ transplantation and certain hematological malignancies. In the current study, generation of an ssDNA aptamer (Apt51) against CD25 is reported. Apt51 bound to CD25 with high affinity (Kd=13...

Being one type of pattern recognition receptors (PRRs), lectins exhibit a crucial role in the defense mechanism of invertebrates which are deficient in an adaptive immune system. A new C-type lectin called FmLC3 was isolated from hepatopancreas of Fenneropenaeus merguiensis by cloning approaches, RT-PCR and 5' and 3' RACE (rapid amplification of cDNA ends). A full-length cDNA of FmLC3 contains 607 bp with one open reading frame of 480bp, encoding a 159-amino acids peptide. The predicted primary structure of FmLC3 is composed of a signal peptide, a carbohydrate recognition domain with an EPN motif and one Ca(2+) binding site-2, including a double-loop region assisted by two conserved disulfide linkages...

Senescence is accompanied by loss of reproductive functions. Here we studied reproductive ageing in Drosophila melanogaster males and asked whether the expected decline in male reproductive success is due to diminished functionality of the male accessory gland. The male accessory gland produces the majority of seminal fluid proteins (SFPs) transferred to the female at mating. SFPs induce female post-mating changes and are key to male reproductive success. We measured age-dependent gene expression changes for five representative SFP genes in males from four different age groups ranging from one to six weeks after eclosion...

BACKGROUND AND AIM: The multi-kinase inhibitor regorafenib (REG) was recently demonstrated to be effective in patients with sorafenib (SOR)-resistant hepatocellular carcinoma (HCC). Interestingly, SOR is known to enhance the accumulation of membrane-bound MHC class I polypeptide-related sequence A (mMICA) in HCC cells, and to block production of soluble MICA (sMICA), an immunological decoy. In addition, MICA is associated with HCC in patients with chronic hepatitis C. We have now compared the impact of REG and SOR on MICA in HCC cells, as well as the immunotherapeutic implications thereof...

Dense biomaterial plays an important role in bone replacement. However, it fails to induce bone-cell migration into graft material. In the present study, a novel bone-graft substitute (BGS) consisting of porous gradient HA/ZrO2 composite (PGHC) and gelatin/chitosan slow-release hydrogel containing BMP-2 and BMSCs was designed and prepared to repair lumbar vertebral defects. The morphological characteristics of the BGS evaluated by scanning electron microscope showed that it had a three-dimensional network structure with uniformly distributed chitosan microspheres on the surfaces of the graft material and the interior of the pores...

Hepatocellular carcinoma (HCC), the primary liver malignancy attributes towards the second foremost cause of cancer related mortality. The targeted chemotherapeutic agent, sorafenib is known to exhibit a statistically significant but limited overall survival advantage in advanced HCC. However, the individual patient response towards sorafenib varies drastically with most of them demonstrating stable disease (SD), few with partial response (PR) and very rare complete response (CR). Progressive disease (PD) despite the treatment has also been demonstrated in many patients indicating drug resistance...

Cell cloning and subsequent process development activities are on the critical path directly impacting the timeline for advancement of next generation therapies to patients with unmet medical needs. The use of stable cell pools for early stage material generation and process development activities is an enabling technology to reduce timelines. To successfully use stable pools during development, it is important that bioprocess performance and requisite product quality attributes be comparable to those observed from clonally derived cell lines...

Aberrant activation of Hedgehog (HH)/GLI signaling is causally involved in numerous human malignancies, including basal cell carcinoma (BCC) and medulloblastoma. HH pathway antagonists targeting Smoothened (SMO), an essential effector of canonical HH/GLI signaling, show significant clinical success in BCC patients and have recently been approved for the treatment of advanced and metastatic BCC. However, rapid and frequent development of drug resistance to SMO inhibitors (SMOi) together with severe side effects caused by prolonged SMOi treatment call for alternative treatment strategies targeting HH/GLI signaling downstream of SMO...

Mitochondria play a significant role in shaping cytosolic Ca(2+) signals. Thus, Ca(2+) transfers across the mitochondrial membrane are much studied, not only in intact cells but also in artificial systems such as mitochondrial suspensions or permeabilised cells. Observed rates of Ca(2+) changes vary by at least one order of magnitude. In this work, we investigate the relationship between the Ca(2+) dynamics observed in various experimental conditions using a computational model calibrated on experimental data...

It recently been demonstrated that predictive learning induces a persistent accumulation of delta-opioid receptors (DOPr's) at the somatic membrane of cholinergic interneurons (CINs) in the nucleus accumbens shell (Nac-S). This accumulation is required for predictive learning to influence subsequent choice between goal-directed actions. The current experiments investigated the local neurochemical events responsible for this translocation. We found that (1) local administration of substance P into multiple striatal sub-territories induced DOPr translocation and (2) that this effect was mediated by the NK1 receptor, likely through its expression on CINs...

AIM: Junctophilins (JPs), a protein family of the junctional membrane complex, maintain the close conjunction between cell surface and intracellular membranes in striate muscle cells mediating the cross talk between extracellular Ca(2+) entry and intracellular Ca(2+) release. The small conductance Ca(2+) -activated K(+) channels are activated by the intracellular calcium and play an essential role in the cardiac action potential profile. Molecular mechanisms of regulation of the SK channels are still uncertain...
