Many emotionally-disturbed children who have been maltreated and are legally separated from their parents or primary caregivers live in group homes and receive compulsory education. Such institutions provide various special intervention programs. Taiko-ensou, a Japanese style of group drumming, is one such program because playing drums in a group may improve children's emotional well-being. However, evidence for its efficacy has not been well established at the biological level. In this study, we measured salivary levels of oxytocin (OT), a neuropeptide associated with social memory and communication, in three conditions (recital, practice, and free sessions) in four classes of school-aged children...

Colored waterborne polyurethanes have been widely used in paintings, leathers, textiles, and coatings. Here, a series of black waterborne polyurethanes (WPUs) with different ratios of black dye, Sudan Black B (SDB), were prepared by step-growth polymerization. WPU emulsions as obtained exhibit low particle sizes and remarkable storage stability at the same time. At different dye loadings, essential structural, statistical and thermal properties are characterized. FTIR (fourier transform infrared) spectra indicate that SDB is covalently linked into waterborne polyurethane chains...

Julia McReynolds-Pérez
BACKGROUND: This paper analyzes the strategies used by activist health professionals in Argentina who justify providing abortion despite legal restrictions on the procedure. These "insider activists" make a case for abortion rights by linking pregnancy termination to a woman's ability to exert agency at a key point in her reproductive life, and argue that refusing women access to the procedure constitutes a grievous health risk. This argument frames pregnancy termination as an issue of empowerment and also as a medical necessity...

The advent of trastuzumab and other human epidermal growth factor receptor 2 (HER2)-directed therapies has revolutionized the treatment of metastatic HER2-positive breast cancer, leading to prolonged survival and appreciable clinical benefit for a substantial subset of patients. Previously, in a retrospective study at our institution, we observed that nearly 10% of patients achieved a durable complete remission (DCR) following a combination of HER2-directed therapy and cytotoxic chemotherapy. We are currently expanding this study to include patients who were treated since the initial introduction of trastuzumab...

Surface-enhanced Raman scattering (SERS) based biosensing in biological fluids is constrained by nonspecific macromolecules adsorptions and disposable property of the SERS substrate. Here, novel multi-Au nanoparticles-embedded mesoporous silica microspheres (AuNPs/mSiO2) was prepared using a one-pot method, which served as reliable substrates for SERS enhancement associated with salient features of self-filtering ability and reusability. The fabrication and physical characterization of AuNPs/mSiO2 microspheres were discussed, and SERS activity of this novel substrates was investigated by using 4-mercaptobenzoic acid (4-MBA) as Raman probe...

Direct-reading gas monitors warn workers of the risk of potentially fatal hydrogen sulfide (H2S) exposures that may arise during manure handling. Low-cost, low-maintenance H2S monitors are available from many manufacturers, but differences in their features and performance make selection challenging for farmers. Moreover, little information is available on the practical maintenance and performance of these devices in agricultural environments. The objective of this study was to provide information to agricultural workers to aid in the selection, maintenance, and use of low-cost H2S monitors...

Social work is a profession that seeks to enhance the well-being of all people and promote social justice and social change through a range of activities, such as direct practice, community organizing, social and political action, and policy development. However, the current literature suggests that the profession's focus on social justice and social action are weakening, replaced by individualism and therapeutic interventions. This article examines data derived from a survey of 188 National Association of Social Workers members from Maryland; Virginia; and Washington, DC, to explore levels of social action participation among social workers and determine whether identifying as a macro-level practitioner would predict higher levels of social action activity compared with being a micro-level practitioner...

The term "whole-person cancer care"-an approach that addresses the needs of the person as well as treating the disease-is more widely understood in the United Kingdom than its synonym "integrative oncology." The National Health Service (NHS) provides free access to care for all, which makes it harder to prioritize NHS funding of whole-person medicine, where interventions may be multimodal and lacking in cost-effectiveness data. Despite this, around 30% of cancer patients are known to use some form of complementary or alternative medicine (CAM)...

In this feature article, we discuss in detail developmental bottleneck issues in Raman spectroscopy in its early stages and surface-enhanced Raman spectroscopy (SERS) in the past four decades. We divide SERS research into two different directions with different targets. Fundamental research is extending the limits of SERS to single-molecule, sub-nanometer resolution and femtosecond processes. In contrast, practical research is expanding the range of applications with the aim of providing versatile analytical tools for surface, materials, life, environmental, forensic and food sciences and also commercial instruments for use in daily life...

In the 1950s, embryology in socialist China underwent a series of changes that adjusted the disciplinary apparatus to suit socialism and the national goal of self-reliance. As the Communist state called on scientists to learn from the Soviets, embryologists' comprehensive view on heredity, which did not contradict Trofim Lysenko (1898-1976)'s doctrines, provided a space for them to advance their discipline. Leading scientists, often trained abroad in the tradition of experimental embryology, rode on the tides of Maoist ideology and repositioned their research...

Introduction: Afghanistan has a high maternal mortality rate of 400 per 100,000 live births. Although direct causes of maternal morbidity and mortality in Afghanistan include hemorrhage, obstructed labor, infection, high blood pressure, and unsafe abortion, the high burden of diseases responsible for maternal mortality arises in large part due to social determinants of health. The focus of this literature review is to examine the impact of various social determinants of health on maternal health in Afghanistan, filling an important gap in the existing literature...
