Nanomachine Networks: Functional All-Enzyme Hydrogels from Photochemical Cross-Linking of Glucose Oxidase.

Enzymes are attractive as catalysts due to their specificity and biocompatibility; however, their use in industrial and biomedical applications is limited by stability. Here, we present a facile approach for enzyme immobilization within "all-enzyme" hydrogels by forming photochemical covalent cross-links between the enzyme glucose oxidase. We demonstrate that the mechanical properties of the enzyme hydrogel can be tuned with enzyme concentration and the data suggests that the dimeric nature of glucose oxidase results in unusual gel formation behavior which suggests a degree of forced induced dimer dissociation and unfolding.

Respiratory muscle endurance training among patients with chronic diseases: A systematic review of available evidence.

It includes both randomized and non-randomized controlled trials implementing this exercise training modality performed either alone or in combination with other interventions. It was conducted using the following databases: PubMed, Google Scholar, Physiotherapy Evidence Database (PEDro), Embase, CINAHL, CENTRAL, Cochrane and ReeDOC.

A common neural response to perceiving but not implicitly regulating infant and adult affect in postpartum mothers.

The transition to parenthood requires parents develop caregiving behaviors, such as the ability to identify their infant's emotions and regulate their own emotional response. Research has identified patterns of neural activation in parenting contexts that are interpreted as socioemotional processing. However, no prior research has directly tested whether mothers' neural responses to their infant's affect are the same as those involved in emotion perception/experience and regulation in other contexts.

Maternal interpretation of infant emotions related to mothers' mindfulness and mother-infant stress.

We aimed to identify maternal characteristics predicting interpretation of infant emotions, as well as relations between such interpretations and mother-infant stress. Specifically, we investigated (1) prospective associations between maternal dispositional mindfulness and interpretation of infant emotions, and (2) concurrent associations between maternal interpretation of infant emotions and mothers' and infants' cortisol during a dyadic stressor in a non-clinical community sample ( = 78) of mother-infant dyads. Mothers completed the Five Facet Mindfulness Questionnaire at 3 months postnatal, and the IFEEL Picture infant emotion interpretation task at 6 months postnatal.

Childhood maltreatment exposure is differentially associated with transdiagnostic perinatal depression symptoms.

Unlabelled: History of childhood maltreatment (CM) is common and robustly associated with prenatal and postpartum (perinatal) depression. Given perinatal depression symptom heterogeneity, a transdiagnostic approach to measurement could enhance understanding of patterns between CM and perinatal depression.

Methods: In two independently collected samples of women receiving care at perinatal psychiatry clinics (n = 523 and n = 134), we categorized longitudinal symptoms of perinatal depression, anxiety, stress, and sleep into transdiagnostic factors derived from the Research Domain Criteria and depression literatures.

Detection of dysplasia in peripheral blood: Proposal of an algorithm to detect myelodysplastic syndromes and chronic myelomonocytic leukemias on a high-speed technical platform using the Sysmex XN™ analyser.

Introduction: Chronic Myelomonocytic Leukemia (CMML) and Myelodysplastic Syndromes (MDS) are increasingly represented in the general population. We propose a screening strategy based on algorithms calculated from quantitative and analytical data from the XN analyser.

Materials And Methods: We tested the performance of previously published MDS and CMML scores on an evaluation cohort of 749 individual eligible patients over 50 years of age.

Visualization of Self-Assembly and Hydration of a β-Hairpin through Integrated Small and Wide-Angle Neutron Scattering.

Fundamental understanding of the structure and assembly of nanoscale building blocks is crucial for the development of novel biomaterials with defined architectures and function. However, accessing self-consistent structural information across multiple length scales is challenging. This limits opportunities to exploit atomic scale interactions to achieve emergent macroscale properties.

PDMS as a Substrate for Lipid Bilayers.

PDMS (polydimethylsiloxane) is a cheap, optically clear polymer that is elastic and can be easily and quickly fabricated into a wide array of microscale and nanoscale architectures, making it a versatile substrate for biophysical experiments on cell membranes. It is easy to imagine many new experiments will be devised that require a bilayer to be placed upon a substrate that is flexible or easily cast into a desired geometry, such as in lab-on-a-chip, organ-on-chip, and microfluidic applications, or for building accurate membrane models that replicate the surface structure and elasticity of the cytoskeleton. However, PDMS has its limitations, and the extent to which the behavior of membranes is affected on PDMS has not been fully explored.

Social determinants of perinatal mental health during the COVID-19 pandemic.

Objective: We sought to clarify relevant social-structural determinants of perinatal mental health-material and social resources, as well as pandemic employment-related stressors, in White and BIPOC child-bearers-toward building comprehensive risk screening and prevention/intervention models that can alleviate health disparities. Each of these determinants was hypothesized to contribute to perinatal symptoms in ways that disproportionately benefit White child-bearers.

Method: A community sample of Illinois child-bearers (n = 409 pregnant, 122 new parents) completed online questionnaires from May 2020-June 2021.

Positive affect improves a transdiagnostic model of perinatal depression symptoms.

Introduction: Accurate measurement of perinatal depression is vital. We aimed to 1) test whether a factor that measured positive affect (PA) bettered a transdiagnostic model of depression symptoms and 2) replicate the model in a second sample.

Methods: We conducted secondary analyses from two samples (n's = 657 and 142) of women in treatment at perinatal psychiatric clinics.

[Physical activity and lung cancer: A synthesis of the literature].

Introduction: Physical activity (PA) has its place in the continuum of care, the objective being to limit alterations associated with cancer and its treatments. This review of the literature collates the evidence and current data relating to PA carried out at different periods of treatment for lung cancer.

State Of The Art: PA is safe and feasible in patients with lung cancer throughout their oncologic treatment.

Bicornuate uterus and pregnancy: ambiguity diagnosis (a case report).

The frequency of uterine malformations is estimated in the general population to be between 1 and 4%. The bicornuate uterus accounts for about half of uterine abnormalities. The conception of a pregnancy and its evolution to term on this uterine abnormality is rare.

The ability of trimethylamine N-oxide to resist pressure induced perturbations to water structure.

Trimethylamine N-oxide (TMAO) protects organisms from the damaging effects of high pressure. At the molecular level both TMAO and pressure perturb water structure but it is not understood how they act in combination. Here, we use neutron scattering coupled with computational modelling to provide atomistic insight into the structure of water under pressure at 4 kbar in the presence and absence of TMAO.

Associations Between Direct and Indirect Forms of Racism Exposure and Stress-Induced Inflammatory Response and Health in Pregnancy.

Theory and research suggest chronic direct and indirect exposures to racism impact health, and stress-responsive inflammation may play a role in these paths. This study examines links between forms of racism-related stress, salivary markers of inflammation during acute psychosocial stress, and perinatal mental and physical health in a racially heterogenous sample. Pregnant people (n = 108, 27% non-white) self-reported personal and vicarious exposure to racism (racial microaggressions, online racism, overt racial/ethnic discrimination) and racial collective self-esteem, as well as affective symptoms and general physical health.

A study of the interaction between TMAO and urea in water using NMR spectroscopy.

Trimethylamine -oxide (TMAO) and urea are small organic biological molecules. While TMAO is known as a protective osmolyte that promotes the native form of biomolecules, urea is a denaturant. An understanding of the impact of TMAO and urea on water structure may aid in uncovering the molecular mechanisms that underlie this activity.

[Preparing for thoraco-abdominal surgery: What's in it for the physiotherapist?].

Introduction: Physiotherapy before thoraco-abdominal surgery aims to optimize the patient's cardiorespiratory fitness, in order to limit his alterations in the immediate postoperative period and to reduce postoperative morbidity. This support also aims to make eligible for surgery the patient who is not initially. This review of the literature addresses chest physiotherapy and exercise training that the patient can benefit.

Mindfulness and acceptance-based interventions with Black Americans: A meta-analysis of intervention efficacy for depressive symptoms.

Objective: A growing literature supports mindfulness and acceptance-based interventions (MABIs) for depression prevention and treatment with individuals from dominant cultural groups, and MABIs have been theorized to be well suited to resonate with individuals from nondominant groups. The aim of the current meta-analysis was to determine whether this promise is realized in practice by evaluating the efficacy of MABIs for depression symptoms in Black Americans.

Method: Thirty studies with an adequate proportion (>20%) of Black Americans were identified using previous reviews and electronic databases, yielding a total of 1,703 participants with an average proportion of 70% Black Americans.

Bridging Structure, Dynamics, and Thermodynamics: An Example Study on Aqueous Potassium Halides.

Aqueous salt systems are ubiquitous in all areas of life. The ions in these solutions impose important structural and dynamic perturbations to water. In this study, we employ a combined neutron scattering, nuclear magnetic resonance, and computational modeling approach to deconstruct ion-specific perturbations to water structure and dynamics and shed light on the molecular origins of bulk thermodynamic properties of the solutions.

Reduced prefrontal cortex response to own vs. unknown emotional infant faces in mothers with bipolar disorder.

Motherhood involves functional brain adaptations within a broad neural network purported to underlie sensitive caregiving behavior. Bipolar disorder (BD) is associated with aberrant brain response to emotional faces within a similar network, which may influence BD mothers' sensitivity to infant faces. This functional magnetic resonance imaging (fMRI) study aimed to investigate whether mothers with BD display aberrant neural responses to own infant faces compared to healthy mothers.

Patients' Perceptions Of Perinatal Depression Screening: A Qualitative Study.

Screening for perinatal depression is a clinical approach to identifying women in need of mental health diagnoses, referral, and treatment. Many states mandate screening for perinatal depression, but it remains unclear whether screening leads to increased access to treatment and better health outcomes. The aim of this qualitative study was to identify how women from diverse backgrounds perceive the quality of perinatal depression screening and whether the perceived quality affected their decisions about mental health care.

Impact of maternal trauma-related psychopathology and life stress on HPA axis stress response.

To understand and curb intergenerational transmission of stress-related disorder, it is important to identify how trauma-related psychopathology in mothers impacts their psychophysiological stress regulation, particularly in the context of parenting their infants. In this study we investigated associations between mothers' trauma-related psychopathology and life stress and HPA axis response to a personally relevant stressor (infant separation stress) in a non-clinical sample followed longitudinally postpartum. A community sample of low-income mothers (n = 73) and their infants completed laboratory sessions at 3, 6, 12, and 18 months postnatal, and salivary cortisol samples collected before and after dyadic stress tasks at the latter three sessions.

The Indirect Effect of Parental Intolerance of Uncertainty on Perinatal Mental Health via Mindfulness During COVID-19.

Objectives: The COVID-19 pandemic is associated with mental health difficulties, especially during pregnancy and early postpartum. Intolerance of uncertainty (IU) and reduced capacity for mindfulness-a protective factor for child-bearers-may be particularly relevant factors driving mental health problems given the unpredictable nature of the pandemic. The current study aims to shed light on modifiable paths to perinatal psychological distress by testing whether there is an indirect effect of IU on psychological symptoms through a perceived reduction in mindfulness during the pandemic.

Mothers' neural response to valenced infant interactions predicts postpartum depression and anxiety.

It is currently unknown whether differences in neural responsiveness to infant cues observed in postpartum affective disturbance are specific to depression/anxiety or are better attributed to a common component of internalizing distress. It is also unknown whether differences in mothers' brain response can be accounted for by effects of past episodes, or if current neural processing of her child may serve as a risk factor for development of future symptoms. Twenty-four mothers from a community-based sample participated in an fMRI session viewing their 3-month- old infant during tasks evoking positive or negative emotion.

A deep learning based multiscale approach to segment the areas of interest in whole slide images.

This paper addresses the problem of liver cancer segmentation in Whole Slide Images (WSIs). We propose a multi-scale image processing method based on an automatic end-to-end deep neural network algorithm for the segmentation of cancerous areas. A seven-level gaussian pyramid representation of the histopathological image was built to provide the texture information at different scales.
