Polymer functionalization strategies have recently attracted considerable attention for several applications in biomaterials science. In particular, technological advancements in medical imaging have focused on the design of polymeric matrices to improve non-invasive approaches and diagnostic accuracy. In this scenario, the use of microwave irradiation of aqueous solutions containing appropriate combinations of polymers is gaining increasing interest in the synthesis of sterile hydrogels without using monomers, eliminating the need to remove unreacted species...

Toshiko Ichiye
The discovery of microbial communities in extreme conditions that would seem hostile to life leads to the question of how the molecules making up these microbes can maintain their structure and function. While microbes that live under extremes of temperature have been heavily studied, those that live under extremes of pressure, or "piezophiles", are now increasingly being studied because of advances in sample collection and high-pressure cells for biochemical and biophysical measurements. Here, adaptations of enzymes in piezophiles against the effects of pressure are discussed in light of recent experimental and computational studies...

This study employed secondary analyses of existing ecological momentary assessment (EMA) data to characterize hostile and irritable affect in the day-to-day experience of 52 smokers with, and 65 smokers without, posttraumatic stress disorder (PTSD). EMA monitoring occurred over a mean of 8.2 days, and participants responded to an average of 2.8 random prompts/day. Analyses included Wilcoxon rank sum tests of group differences, and path analyses of cross-lagged multilevel models. Participants with PTSD endorsed a significantly higher proportion of total EMA entries indicating hostile affect and irritable affect than did individuals without PTSD...

Stem cell transplantation is a promising therapeutic strategy for myocardial infarction. However, transplanted cells face low survival rates due to oxidative stress and the inflammatory microenvironment in ischemic heart tissue. Melatonin has been used as a powerful endogenous antioxidant to protect cells from oxidative injury. However, melatonin cannot play a long lasting effect against the hostile microenvironment. Nano drug delivery carriers have the ability to protect the loaded drug from degradation in physiological environments in a controlled manner, which results in longer effects and decreased side effects...

Phenotypically-heterogeneous micro-environments emerge as biofilms mature across different environments. Phenotypic-heterogeneity in biofilm sub-populations not obeying quorum sensing-dictated, collective group-behavior, may be considered as a strategy allowing non-conformists to survive hostile conditions. Heterogeneous phenotype development has been amply studied with respect to gene expression and genotypic changes, but 'biofilm genes' responsible for pre-programmed development of heterogeneous micro-environments in biofilms have never been discovered...

Interfacing biomolecules with functional materials is a key strategy toward achieving externally-triggered biological function. The rational integration of functional proteins, such as enzymes, with plasmonic nanostructures that exhibit unique optical properties such as photothermal effect provides a means to externally control the enzyme activity. However, due to the labile nature of enzymes, the photothermal effect of plasmonic nanostructures is mostly utilized for the enhancement of the biocatalytic activity of thermophilic enzymes...

In January 2017, the UK Government made public a Memorandum of Understanding (MoU) between the Department of Health, National Health Service (NHS) Digital and the Home Office. This Memorandum allows for the more expedited sharing of a patient's non-clinical data, specifically from the NHS England to the Home Office. The Government justified the MoU as in the 'public interest to support effective immigration enforcement'. In this review, we seek to unpack this justification by providing, first, a background to the MoU, placing it in the context of creating a 'hostile environment' for migrants - a project initially sought by Theresa May in her time as Home Secretary...

Ischemic stroke represents the leading cause of adult neurological disability, with no effective therapeutic strategy. Stem cell transplantation promises a new promising for treating stroke, via cell replacement and cytokines paracrine. However, due to the effect of hostile immune microenvironment, the survival and differentiation of stem cells is limited in vivo. Furthermore, the delayed inflammatory response to stroke induced secondary neurological injury. IFN-γ as pro-inflammatory cytokine has the potential to protect stem cell population during inflammatory response, as well stimulates neurogenesis of stem cells...

People diagnosed with Internet gaming disorder (IGD) have been frequently reported to experience depression, anxiety, and hostility. Emotional regulation contributes to these mood symptoms. This study evaluated emotional regulation in subjects with IGD and examined relationships between emotional regulation, depression, anxiety, and hostility in young adults with IGD. We recruited 87 people with IGD and a control group of 87 people without a history of IGD. All participants underwent a diagnostic interview based on the IGD criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, and they completed a questionnaire on emotional regulation, depression, anxiety, and hostility...

Hate crimes have been found to have more severe consequences than other parallel crimes that were not motivated by the offenders' hostility toward someone because of their real or perceived difference. Many countries today have hate crime laws that make it possible to increase the penalties for such crimes. The main critique against hate crime laws is that they punish thoughts. Instead, proponents of hate crime laws argue that sentence enhancement is justified because hate crimes cause greater harm. This study compares consequences of victimization across groups of victims to test for whom hate crimes hurt more...

Research suggests that aggressive individuals exhibit a strong tendency to attribute hostile intent to the behavior of others when confronted with an ambiguous social situation. The vignettes method has become a standard procedure to assess hostile attributions. Vignettes represent incomplete ambiguous social stories, in which the subjects experience a negative outcome and are asked to attribute intent to the provocateur's action. This article explores the ways in which subjects perceive ambiguous social situations and other people's intentions, their tendency to refer negative outcome to oneself, and the components defining hostility in the interpersonal relationships...
