Mechanisms of Intracellular Communication in Cancer and Pathogen Spreading.

Cell-to-cell interactions are essential for proper development, homeostasis, and complex syncytia/organ formation and function. Intercellular communication are mediated by multiple mechanisms including soluble mediators, adhesion molecules and specific mechanisms of cell to cell communication such as Gap junctions (GJ), tunneling nanotubes (TNT), and exosomes. Only recently, has been discovered that TNTs and exosomes enable the exchange of large signaling molecules, RNA, viral products, antigens, and organelles opening new avenues of research and therapeutic approaches.

Correlative Imaging to Detect Rare HIV Reservoirs and Associated Damage in Tissues.

Correlative light-electron microscopy (CLEM) has evolved in the last decades, especially after significant developments in sample preparation, imaging acquisition, software, spatial resolution, and equipment, including confocal, live-cell, super-resolution, and electron microscopy (scanning, transmission, focused ion beam, and cryo-electron microscopy). However, the recent evolution of different laser-related techniques, such as mass spectrometry imaging (MSI) and laser capture microdissection, could further expand spatial imaging capabilities into high-resolution OMIC approaches such as proteomic, lipidomics, small molecule, and drug discovery. Here, we will describe a protocol to integrate the detection of rare viral reservoirs with imaging mass spectrometry.

SPR spectroscopic analysis of myosin binding to wild type and mutant UNC45B.

UNC45B is a multidomain molecular chaperone that is essential for the proper folding and function of myosin. It has previously been demonstrated that the UCS domain is responsible for the chaperoning function of UNC45B and that removing its client-binding loop leads to a significant change in its solution conformation and a reduced chaperoning function. Here, we report the direct quantification of affinities of myosin binding to wild type and mutant UNC45B using surface plasmon resonance (SPR) spectroscopy.

Applying the WHO INSPIRE Framework to Ending Violence Against Pregnant Women and Unborn Children: A Case Study in Vietnam.

This article adapted the INSPIRE framework, developed by the World Health Organization to prevent violence against children, to the systematic analysis of city-level healthcare services for pregnant women who experienced intimate partner violence. A mixed-methods study conducted in-depth interviews with 22 health and social care professionals and 140 pregnant women in Vietnam. The women were more likely to report limited system-level support for partners regarding violence and mental health, while the professionals perceived more weaknesses in policies and management of services.

The hypoxia-regulated ectonucleotidase CD73 is a host determinant of HIV latency.

Deciphering the mechanisms underlying viral persistence is critical to achieving a cure for human immunodeficiency virus (HIV) infection. Here, we implement a systems approach to discover molecular signatures of HIV latently infected CD4 T cells, identifying the immunosuppressive, adenosine-producing ectonucleotidase CD73 as a key surface marker of latent cells. Hypoxic conditioning, reflecting the lymphoid tissue microenvironment, increases the frequency of CD73 CD4 T cells and promotes HIV latency.

Positive Effect of Green Photo-Selective Filter on Graft Union Formation in Tomatoes.

This study investigated the effects of green and red photo-selective filters (shade nets) on the process of graft union formation (healing and acclimation) in grafted tomato plants. The research evaluated oxidative stress, physiological characteristics, and anatomical development of graft unions. Plants were subjected to green-netting, red-netting, and no-netting treatments for 28 days, starting 4 days after grafting.

Reducing Stigma Toward People with Serious Mental Illness Through a Virtual Reality Intervention: A Randomized Controlled Trial.

Stigma toward people with serious mental illnesses (SMI), like schizophrenia, is a serious global public health challenge that limits the quality of life of those affected and poses a major barrier that keeps people from seeking professional help. There is an urgent need for novel, effective, and scalable interventions to decrease stigmatized perceptions of chronic psychotic disorders and to reduce the health burden imposed by them. We conducted a randomized controlled trial to assess the impact of a new immersive virtual reality game () on the level of stigma toward people with SMI, measured by the Attribution questionnaire (AQ-27).

PROTOCOL: School-based interventions for reducing disciplinary school exclusion: An updated systematic review.

The primary goal of the present mixed methods review is to systematically examine the available evidence for the effectiveness of different types of school-based interventions for reducing disciplinary school exclusion. Quantitative evidence will help to understand the overall size of the impact, as well as the factors that better explain it. Qualitative evidence will help to better understand how these programmes may work, and what factors aid or hinder implementation and success.

The role of tunneling nanotubes during early stages of HIV infection and reactivation: implications in HIV cure.

Tunneling nanotubes (TNTs), also called cytonemes or tumor microtubes, correspond to cellular processes that enable long-range communication. TNTs are plasma membrane extensions that form tubular processes that connect the cytoplasm of two or more cells. TNTs are mostly expressed during the early stages of development and poorly expressed in adulthood.

Measuring antenatal depressive symptoms across the world: A validation and cross-country invariance analysis of the Patient Health Questionnaire-9 (PHQ-9) in eight diverse low-resource settings.

Measures that produce valid and reliable antenatal depressive symptom scores in low-resource country contexts are important for efforts to illuminate risk factors, outcomes, and effective interventions in these contexts. Establishing the psychometric comparability of scores across countries also facilitates analyses of similarities and differences across contexts. To date, however, few studies have evaluated the psychometric properties and comparability of the most widely used antenatal depressive symptom measures across diverse cultural, political, and social contexts.

Identification, Quantification, and Characterization of HIV-1 Reservoirs in the Human Brain.

The major barrier to cure HIV infection is the early generation and extended survival of HIV reservoirs in the circulation and tissues. Currently, the techniques used to detect and quantify HIV reservoirs are mostly based on blood-based assays; however, it has become evident that viral reservoirs remain in tissues. Our study describes a novel multi-component imaging method (HIV DNA, mRNA, and viral proteins in the same assay) to identify, quantify, and characterize viral reservoirs in tissues and blood products obtained from HIV-infected individuals even when systemic replication is undetectable.

Associations Between ADHD Symptoms and Maternal and Birth Outcomes: An Exploratory Analysis in a Multi-Country Cohort of Expectant Mothers.

Objective: ADHD symptoms can adversely impact functioning in a range of domains relevant for maternal well-being and fetal development; however, there has been almost no research examining their impact during pregnancy. We aimed to address this gap.

Method: We used data ( = 1,204) from a longitudinal birth cohort study spanning eight countries to address this gap.

Associations between Student-Teacher Bonds and Oppositional Behavior Against Teachers in Adolescence: A Longitudinal Analysis from Ages 11 to 15.

Prior research has found evidence for a positive effect of student-teacher bonds on children's behavior. However, little research has investigated these relations following a transactional model of child development. This study investigated the bidirectional associations between student-teacher relationships and oppositional behaviors towards teachers using the 'Zurich Project on the Social Development from Childhood to Adulthood' (n = 1527; median ages 11, 13 and 15; 49% female).

The influence of childhood abuse and prenatal intimate partner violence on childbirth experiences and breastfeeding outcomes.

Background: Despite the detrimental effects and life-course health consequences of violence exposure, relatively few studies have adequate capacity to investigate the evolution of violence from childhood to motherhood.

Objective: This study aims to examine the cyclical nature of childhood abuse and prenatal inter-partner violent victimization (p-IPV) and its adverse impact on childbirth trauma and exclusive breastfeeding (EBF) practice in Vietnam.

Method: Using a prospective birth cohort, 150 pregnant women were recruited in the third trimester of pregnancy in Hue city in central Vietnam (Wave 1-Baseline) and re-interviewed approximately three months after delivery (Wave 2-Follow-up).

Patterns of adverse childhood experiences and associations with prenatal substance use and poor infant outcomes in a multi-country cohort of mothers: a latent class analysis.

Background: This paper enumerates and characterizes latent classes of adverse childhood experiences and investigates how they relate to prenatal substance use (i.e., smoking, alcohol, and other drugs) and poor infant outcomes (i.

Infection of lung megakaryocytes and platelets by SARS-CoV-2 anticipate fatal COVID-19.

SARS-CoV-2, although not being a circulatory virus, spread from the respiratory tract resulting in multiorgan failures and thrombotic complications, the hallmarks of fatal COVID-19. A convergent contributor could be platelets that beyond hemostatic functions can carry infectious viruses. Here, we profiled 52 patients with severe COVID-19 and demonstrated that circulating platelets of 19 out 20 non-survivor patients contain SARS-CoV-2 in robust correlation with fatal outcome.

Innovative Technology-Based Interventions to Reduce Stigma Toward People With Mental Illness: Systematic Review and Meta-analysis.

Background: Stigma toward people with mental illness presents serious consequences for the impacted individuals, such as social exclusion and increased difficulties in the recovery process. Recently, several interventions have been developed to mitigate public stigma, based on the use of innovative technologies, such as virtual reality and video games.

Objective: This review aims to systematically review, synthesize, measure, and critically discuss experimental studies that measure the effect of technological interventions on stigmatization levels.

Perceived stress during the prenatal period: assessing measurement invariance of the Perceived Stress Scale (PSS-10) across cultures and birth parity.

Maternal prenatal stress places a substantial burden on mother's mental health. Expectant mothers in low- and middle-income countries (LMICs) have thus far received less attention than mothers in high-income settings. This is particularly problematic, as a range of triggers, such as exposure to traumatic events (e.

An Umbrella Review of the Literature on Perinatal Domestic Violence: Prevalence, Risk Factors, Possible Outcomes and Interventions.

Perinatal domestic violence (P-DV) is a common form of violence experienced by women and is associated with adverse impacts on their own physical and mental health and that of their offspring. Illuminating the risk factors for, potential effects of, and promising interventions to reduce P-DV is essential for informing policies to tackle P-DV and mitigate its negative impacts. This umbrella review of recent high-quality systematic reviews and meta-analyses of worldwide research on P-DV provides a systematic synthesis of current knowledge relating to the prevalence, risk factors for, possible outcomes of and interventions to reduce and prevent P-DV.

Feasibility of a birth-cohort in Pakistan: evidence for better lives study.

Background: Evidence for Better Lives Study Foundational Research (EBLS-FR) is a preliminary endeavor to establish the feasibility of a global birth cohort, and within this feasibility study, piloting the research instrument, with participants from eight lower middle-income countries across the globe. It aims to investigate mediators and moderators of child development and wellbeing; it envisages informing policy and practice change to promote child health and wellbeing globally. Pakistan is one of the resource poor lower middle-income country (LMIC) taking part in this global birth cohort; we report the feasibility of establishing such a birth cohort in Pakistan.

Pannexin-1 channel opening is critical for COVID-19 pathogenesis.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) rapidly rampaged worldwide, causing a pandemic of coronavirus disease (COVID -19), but the biology of SARS-CoV-2 remains under investigation. We demonstrate that both SARS-CoV-2 spike protein and human coronavirus 229E (hCoV-229E) or its purified S protein, one of the main viruses responsible for the common cold induce the transient opening of Pannexin-1 (Panx-1) channels in human lung epithelial cells. However, the Panx-1 channel opening induced by SARS-CoV-2 is greater and more prolonged than hCoV-229E/S protein, resulting in an enhanced ATP, PGE, and IL-1β release.

COVID-19 Lung Pathogenesis in SARS-CoV-2 Autopsy Cases.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a major public health issue. COVID-19 is considered an airway/multi-systemic disease, and demise has been associated with an uncontrolled immune response and a cytokine storm in response to the virus. However, the lung pathology, immune response, and tissue damage associated with COVID-19 demise are poorly described and understood due to safety concerns.

Intergenerational effects of violence on women's perinatal wellbeing and infant health outcomes: evidence from a birth cohort study in Central Vietnam.

Background: Girls exposed to violence have a high risk of being victimized as adults and are more likely than non-abused women to have children who are treated violently. This intergenerational transmission may be especially serious when women suffer violence during pregnancy and early motherhood, as it impairs maternal wellbeing and infant health and development. This study examined the intergenerational effects of being exposed to childhood maltreatment (CM) and prenatal intimate partner violence (p-IPV) on perinatal mental distress and birth outcomes in central Vietnam.
