Stem cell therapy is a promising therapeutic method for the treatment of ischemic heart diseases; however, some challenges prohibit the efficacy after cell delivery due to hostile microenvironment of the injured myocardium. 3D printed pre-vascularized stem cell patch can enhance the therapeutic efficacy for cardiac repair through promotion of rapid vascularization after patch transplantation. In this study, stem cell-laden decellularized extracellular matrix bioinks are used in 3D printing of pre-vascularized and functional multi-material structures...

Social dominance orientation (SDO) is conceived as an individual's level of support for group-based hierarchy in general that causes support for more specific group hierarchies. According to social dominance theory, group differences in SDO underpin ideological and behavioural group differences related to specific group hierarchies. Using representative 5-year longitudinal panel data from New Zealand (N = 3,384), we test whether SDO mediates effects of sex and ethnicity on legitimizing myths (LMs) relating to gender and ethnic hierarchy over time...

INTRODUCTION: The offer of pre-exposure prophylaxis (PrEP) is recommended as an additional option for HIV prevention for people at substantial risk of HIV infection as part of combination HIV prevention approaches. Implementing this depends on integrating PrEP in public health programmes that address risky practices with evidence-based interventions, and that operate in an enabling legal and policy environment for the delivery of health services to those at higher risk of HIV infection...

Novel strategies to combat the ever increasing burden of drug resistance in Mycobacterium tuberculosis (MTB) causing tuberculosis (TB) remains a global concern. The ability of MTB to sense and adapt to restricted iron conditions in the hostile environment is essential for their survival and confers the basis of their success as dreadful pathogen. The striking and clinically relevant virulence trait of MTB is its ability to form biofilms and adhere to the host cells. The present study elucidated the effect of iron deprivation on biofilm formation and cell adherence of Mycobacterium smegmatis, a non-pathogenic surrogate of MTB...

Attacks on peoples' dignity help to produce and maintain stigmatization and interpersonal hostility. As part of an effort to develop innovative measures of possible pathways between structural interventions or socially-disruptive Big Events and HIV outbreaks, we developed items to measure dignity denial. These measures were administered to 300 people who inject drugs (PWID), 260 high-risk heterosexuals who do not inject drugs, and 191 men who have sex with men who do not inject drugs (MSM). All of the PWID and many of the high risk heterosexuals and MSM were referred to our study in 2012-2015 by a large New York city study that used respondent-driven sampling; the others were recruited by chain-referral...

The aim of this prospective study was to expand previously reported evidence on the 10-year clinical and functional course of borderline personality disorder (BPD) in a Spanish sample. Participants diagnosed with BPD were assessed at baseline and at 10-year follow-up to evaluate BPD symptomatology and other relevant clinical measures, suicidal behavior, dimensional personality traits, Axis I and II comorbidity, use of mental health resources, and psychosocial functioning. At the 10-year follow up, significant improvements were observed on BPD domains, suicidal behavior, and other clinical measures...

Objective: Theories posit that chronically depressed individuals have hostile and submissive interpersonal styles that undermine their interpersonal effectiveness and contribute to the cause and maintenance of their depression. Recent findings support this theory and demonstrate that chronically depressed patients' interpersonal impacts on their therapist become more adaptive (i.e., less hostile and submissive, and more friendly and assertive) during a targeted chronic depression treatment: cognitive-behavioral analysis system of psychotherapy (CBASP)...

Hostile men have reliably displayed an exaggerated sympathetic stress response across multiple experimental settings, with cardiovascular reactivity for blood pressure and heart rate concurrent with lateralized right frontal lobe stress (Trajanoski et al., in Diabetes Care 19(12):1412-1415, 1996; see Heilman et al., in J Neurol Neurosurg Psychiatry 38(1):69-72, 1975). The current experiment examined frontal lobe regulatory control of glucose in high and low hostile men with concurrent left frontal lobe (Control Oral Word Association Test [verbal]) or right frontal lobe (Ruff Figural Fluency Test [nonverbal]) stress...

The battle with human immunodeficiency virus (HIV) has been ongoing for more than 30 years, and although progress has been made, there are still significant challenges remaining. A few unique features render HIV to be one of the toughest viruses to conquer in the modern medicine era, such as the ability to target the host immune system, persist by integrating into the host genome and adapt to a hostile environment such as a single anti-HIV medication by continuously evolving. The finding of combination anti-retroviral therapy (cART) about 2 decades ago has transformed the treatment options for HIV-infected patients and significantly improved patient outcomes...

INTRODUCTION: The Klinefelter syndrome (KS) is a genetic condition characterized by an X supernumerary sex chromosome in males. The syndrome is frequently associated with cognitive impairment. Indeed, the different areas of the executive sphere can be affected such as inhibition, cognitive flexibility but also attentional and visual-spatial domain. Social cognition disorders, predominantly on emotional recognition processes, have also been documented. In addition, the syndrome may be associated with psychiatric symptoms...

The gradual deterioration following central nervous system (CNS) injuries or neurodegenerative disorders is usually accompanied by infiltration of degenerated and apoptotic neural tissue debris. A rapid and efficient clearance of these deteriorated cell products is of pivotal importance in creating a permissive environment for regeneration of those damaged neurons. Our recent report revealed that the phagocytic activity of olfactory ensheathing cells (OECs) can make a substantial contribution to neuronal growth in such a hostile environment...

BACKGROUND: Suicide rates among veterans are disproportionately high compared to rates among the general population. Veterans may experience a number of negative emotions (e.g., anger, self-directed hostility, shame, guilt) during periods of postwar adjustment and reintegration into civilian life that may uniquely confer risk for suicide. Mechanisms of these associations, however, are less well studied. The purpose of the present study was to examine the relationship between negative emotions and suicide risk in veterans through the theoretical framework of the interpersonal theory of suicide...

Solid tumor dissemination from the primary site to the sites of metastasis involves tumor cell transport through the blood or lymph circulation systems. Once the tumor cells enter the bloodstream, they encounter a new hostile microenvironment. The cells must withstand hemodynamic forces and overcome the effects of fluid shear. The cells are exposed to immunological signaling insults from leukocytes, to collisions with erythrocytes, and to interactions with platelets or macrophages. Finally, the cells need to attach to the blood vessel walls and extravasate to the surrounding stroma to form tumor metastases...

Background. Persistent Helicobacter pylori infection may induce several upper gastrointestinal diseases. Two major virulence factors of H. pylori, vacuolating cytotoxin A (VacA) and cytotoxin-associated gene A (CagA), are thought to be associated with the severity of disease progression. The distribution of vacA and cag-pathogenicity island (cag-PAI) alleles varies in H. pylori isolated from patients in different geographic regions. Aim. To assess the association between mixed infection of H. pylori clinical isolates from Taiwanese patients and the severity of gastrointestinal diseases...

OBJECTIVE: We investigated the effects of automatic target detection (ATD) on the detection and identification performance of soldiers. BACKGROUND: Prior studies have shown that highlighting targets can aid their detection. We provided soldiers with ATD that was more likely to detect one target identity than another, potentially acting as an implicit identification aid. METHOD: Twenty-eight soldiers detected and identified simulated human targets in an immersive virtual environment with and without ATD...

For two reasons, communication is one of the major tools in the fight against any Ebola epidemics. Firstly, because Ebola is one of the most easily preventable of all infectious diseases and the thorough application of health-protection measures by the community of the sick persons is the best tool to fight any Ebola epidemic. Secondly, because during the two dozens of known Ebola epidemics health care workers have often met with people's skepticism, or even hostility. However, our review of Ebola communication, as defined by WHO since 2013, shows that it has been marked by a series of errors, as well from a strategic perspective as in its concrete deployment...

The management of ureteral obstruction of malignant origin or complicated benign obstruction continues to be a challenge for the urological community. In this sense, the use of metallic stents could be considered a useful alternative to the conventional drainage techniques, because it accomplishes the resolution of obstruction in a single procedure, without external diversions and without the adverse effects of current diversions. Another important advantage they offer is that they do not need replacement as frequently as double J catheters or nephrostomy tubes require...
