Hydrogel Composition Effects on Performance as Single-Walled Carbon Nanotube Purification Media.

Hydrogel microsphere media allows for postsynthetic purification of single-walled carbon nanotubes (SWNTs), affording characterization and application of their unique (,) chirality-dependent properties. This work reports the characterization of five hydrogel resins, Sephacryl S-100, S-200, S-300, S-400, and S-500, and the implementation of each as a SWNT purification medium. The physiochemical properties of each resin were explored spectroscopically through elemental analyses and with both light and electron microscopy.

Photoinduced Birefringence and Liquid Crystal Orientation on Polymers with Different Azobenzene Content in the Main Chain.

In this paper, we give an overview of novel main-chain azobenzene-based fluorinated poly(arylene ether)s with different content of azo groups, aiming at providing a better understanding of the link between a number of N═N bonds and the macroscopic response of the material. We discuss chemical synthesis and molecular structure and report on a comprehensive analysis of the polymer properties, thermal behavior, and mechanical strength. We show that a higher content of azobenzene moieties reduces the mechanical strength of the polymer materials.

Advancing Late-Life Trauma-Informed Care Education: Development and Evaluation of an Educational Podcast.

Posttraumatic stress disorder (PTSD) may emerge in late life in the context of illness, role changes, and life review, leading to complications in disease management. The "Talking Later" podcast was developed as an accessible educational product to improve knowledge about late-life PTSD. We describe the process of systematically developing a ten-episode podcast following Kern's six-step curricular model.

Comparative study on chromatin loop callers using Hi-C data reveals their effectiveness.

Background: Chromosome is one of the most fundamental part of cell biology where DNA holds the hierarchical information. DNA compacts its size by forming loops, and these regions house various protein particles, including CTCF, SMC3, H3 histone. Numerous sequencing methods, such as Hi-C, ChIP-seq, and Micro-C, have been developed to investigate these properties.

The brain under sexual attack: A brief report on neurobiological disturbances in trauma memory.

Propensity score matching was used to compare SSM/Vs ( = 2984) to their most similar non-SSM/V counterparts ( = 1,355).

Impact of a short online course on the accuracy of non-ophthalmic diabetic retinopathy graders in recognising glaucomatous optic nerves in Vietnam.

Purpose: To test an online training course for non-ophthalmic diabetic retinopathy (DR) graders for recognition of glaucomatous optic nerves in Vietnam.

Methods: This was an uncontrolled, experimental, before-and-after study in which 43 non-ophthalmic DR graders underwent baseline testing on a standard image set, completed a self-paced, online training course and were retested using the same photographs presented randomly. Twenty-nine local ophthalmologists completed the same test without the training course.

Gradient Bundle Analysis of Electric Field Induced Changes in Electron Charge Density.

Applying an electric field (EF) to a molecule is known to induce rearrangement of its electron charge density, ρ(). Previous experimental and computational studies have investigated effects on reactivity by using homogeneous EFs with specific magnitudes and directions to control reaction rates and product selectivity. To best incorporate EFs into experimental design, a more fundamental understanding of how EFs rearrange ρ() is necessary.

The mediating role of coping self-efficacy on social support and PTSD symptom severity among injury survivors.

Background: Social support confers a protective effect against elevated PTSD symptomatology following injury. However, little is known about the mechanisms through which social support conveys this protective mental health effect in injury survivors. Coping self-efficacy is linked to both social support and PTSD symptomatology but has not been examined.

Assessing late-life anxiety in Japanese older adults: psychometric evaluation of the Japanese version of the Geriatric Anxiety Scale.

Background: This study developed a Japanese version of the Geriatric Anxiety Scale (GAS-J) and its short form (GAS-10-J) to evaluate anxiety in Japanese older adults and assess its psychometric properties using a cross-sectional design.

Methods: A total of 331 community-dwelling older adult participants (208 men, 116 women, seven unknowns; mean age = 73.47 ± 5.

Changes in Breast Cancer Risk and Risk Factor Profiles among U.S.-Born and Immigrant Asian American Women Residing in the San Francisco Bay Area.

Background: Breast cancer incidence rates in women of Asian descent have been increasing in the United States and Asia.

Methods: In a case-control study of Asian American women from the San Francisco Bay Area, we assessed associations with birthplace and migration-related characteristics and compared risk factors between Asian American and non-Hispanic White women by birthplace and birth cohort.

Results: Birthplace and migration-related characteristics were associated with breast cancer risk only among women in the younger birth cohort (1951-1984) that comprised 355 cases diagnosed at age ≤55 years and 276 sister and population controls.

Associations between physical health and the alternative model of personality disorders: A cross-sectional age study.

The Alternative Model of Personality Disorders (AMPD) is a relatively new dimensional model of personality disorders (PDs) that assesses two diagnostic constructs: personality functioning and pathological personality traits. Thus far, research on the AMPD among older adults has been limited, but the research that does exist suggests limited generalizability to the unique biopsychosocial context of later life. To further examine the applicability of the AMPD to older adults, the purpose of this study was to examine relationships between the AMPD's two constructs with perceived physical health status among younger and older adult samples.

A generic parallel framework for inferring large-scale gene regulatory networks from expression profiles: application to Alzheimer's disease network.

The inference of large-scale gene regulatory networks is essential for understanding comprehensive interactions among genes. Most existing methods are limited to reconstructing networks with a few hundred nodes. Therefore, parallel computing paradigms must be leveraged to construct large networks.

Self-Other Balance in Context: A Quiet Ego May Be Meaningful and Adaptive in Latinx/Hispanic Cultures and Work Settings.

Quiet ego is a relatively novel, increasingly studied, multi-dimensional concept characterized by a compassionate, interdependent worldview and an adaptive balance between self-interest and concern for others. Quiet ego has been associated with a range of characteristics that can promote relationship quality, responding effectively in the face of challenges, and greater well-being. However, it is currently unknown to what extent quiet ego translates across cultures and settings.

Comparing the Prevalence of Probable and Posttraumatic Stress Disorder in a Sample of U.S. Military Veterans Using the PTSD Checklist.

Motivated reasoning: Election integrity beliefs, outcome acceptance, and polarization before, during, and after the 2020 U.S. Presidential Election.

Unlabelled: The 2020 U.S. Presidential Election required voters to not only form opinions of leading candidates, Donald Trump and Joe Biden, but also to make judgments about the integrity of the election itself and what-if anything-to do about it.

Development and Validation of a Short Form of the Geriatric Anxiety Scale (GAS-12) among Italian Older Adults.

Objectives: We developed a new Italian short version of the Geriatric Anxiety Scale (GAS-12) and evaluated its psychometric properties. The GAS-12 specifically screens for anxiety symptoms in the Italian older adult population by identifying items that best discriminate anxiety in this population.

Methods: In Study 1, we administered the full-length Italian translation of the GAS to 517 older adults and used item response theory to identify the most discriminating items and to develop the short form used in Study 2.

Structure of Galectin-3 bound to a model membrane containing ganglioside GM1.

Galectin-3 (Gal-3) is a β-galactosidase-binding protein involved in various biological processes, including neuronal growth and adhesion. The pairing of Gal-3 with ganglioside GM1's pentasaccharide chain at the outer leaflet of the plasma membrane, which triggers downstream cell-signaling cascades, seems to be involved in these processes. A crucial feature of Gal-3 is its ability to form oligomers and supramolecular assemblies that connect various carbohydrate-decorated molecules.
