Intradermal versus subcutaneous immunization: Effects of administration route using a lipid-PLGA hybrid nanoparticle tuberculosis vaccine.

Tuberculosis (TB) remains a significant global health challenge, latently affecting around a quarter of the global population. The sole licensed TB vaccine, Mycobacterium bovis Bacillus Calmette-Guérin (BCG), shows variable efficacy, particularly among adolescents and adults, underscoring the pressing need for more effective vaccination strategies. The administration route is crucial for vaccine efficacy, and administration via the skin, being rich in immune cells, may offer advantages over conventional subcutaneous routes, which lack direct access to abundant antigen-presenting cells.

Diagnostic Utility of Clinical Neurophysiology in Jerky Movement Disorders: A Review from the MDS Clinical Neurophysiology Study Group.

Background: Myoclonus and other jerky movement disorders are hyperkinetic disorders, the diagnosis of which heavily relies on clinical neurophysiological testing. However, formal diagnostic criteria are lacking, and recently the utility and reliability of these tests have been questioned.

Objective: The aim of this review was to assess the utilization of clinical neurophysiology testing to identify possible gaps and boundaries that might guide the development of new methods for a more precise diagnosis and in-depth understanding of myoclonus.

IAPRD new consensus classification of myoclonus.

Introduction: Recent new advances in myoclonus characterization and etiology justify an update of the 40-year-old respected classification of myoclonus proposed by Marsden, Hallett, and Fahn. New advances include genetic studies and clinical neurophysiology characterization.

Methods: The IAPRD appointed an expert panel to develop a new myoclonus classification.

The farnesoid X receptor activates transcription independently of RXR at non-canonical response elements.

The farnesoid X receptor (FXR) is a nuclear receptor (NR) known to obligately heterodimerize with the retinoid X receptor (RXR). FXR is expressed as four isoforms (α1-α4) that drive transcription from IR-1 (inverted repeat-1) response elements (REs). Recently, we found that FXR isoforms α2/α4 also activate transcription from non-canonical ER-2 (everted repeat-2) REs, mediating most metabolic effects of general FXR activation.

nanoFeatures: a cross-platform application to characterize nanoparticles from super-resolution microscopy images.

Super-resolution microscopy and Single-Molecule Localization Microscopy (SMLM) are powerful tools to characterize synthetic nanomaterials used for many applications such as drug delivery. In the last decade, imaging techniques like STORM, PALM, and PAINT have been used to study nanoparticle size, structure, and composition. While imaging has progressed significantly, image analysis has often not advanced accordingly and many studies remain limited to qualitative and semi-quantitative analyses.

Evaluation of PLGA, lipid-PLGA hybrid nanoparticles, and cationic pH-sensitive liposomes as tuberculosis vaccine delivery systems in a Mycobacterium tuberculosis challenge mouse model - A comparison.

Tuberculosis (TB) continues to pose a global threat for millennia, currently affecting over 2 billion people and causing 10.6 million new cases and 1.3 million deaths annually.

Altered Movement Coordination during Functional Reach Tasks in Patients with Chronic Low Back Pain and Its Relationship to Numerical Pain Rating Scores.

Identifying the effects of pain catastrophizing on movement patterns in people with chronic low back pain (CLBP) has important clinical implications for treatment approaches. Prior research has shown people with CLBP have decreased lumbar-hip ratios during trunk flexion movements, indicating a decrease in the contribution of lumbar flexion relative to hip flexion during trunk flexion. In this study, we aim to explore the relationship between pain catastrophizing and movement patterns during trunk flexion in a CLBP population.

Clinical Dilemmas for the Diagnosis and Treatment of Infection in Children: From Guideline to Practice.

infection is often acquired in early childhood. While most infected children remain asymptomatic, can cause chronic gastritis, gastric ulceration, and, in the long term, gastric cancer. This article aimed to review different diagnostic and treatment options and discuss the challenges associated with applying the current guidelines in the real world.

Substantiating the Short Burst Duration in Cortical Myoclonus.

Background: Myoclonus is characterized by involuntary, shock-like movements, of which cortical (CM) and non-cortical myoclonus (NCM) are most common. Electrophysiology can help differentiate between these subtypes; however, the diagnostic value of several features is largely unknown.

Objective: This study aims to determine the diagnostic value of the burst duration in distinguishing CM and NCM.

Self-perceived functioning, goals and action plans: an evaluation of an ICF-based E-health application in an intervention for people with a combination of mental and physical health conditions.

Purpose: In the BigMove intervention, people with physical and mental health conditions assess their functioning, set goals, and define action plans to achieve their goals recorded in an e-health application using all categories of the International Classification of Functioning, Disability, and Health (ICF). This study investigates whether data from this application can provide insight into participants' self-perceived functioning, goals and action plans and observe changes over time.

Methods: Data from 446 participants were analysed with descriptive statistics to describe self-perceived functioning and the ICF categories related to the 15 most frequently chosen goals.

The BigMove Intervention for People With Physical and Mental Health Conditions: A First Evaluation of Self-Perceived Health, Quality of Life, Coping and Mental and Social Functioning.

Background: The BigMove intervention aims to improve the functioning and quality of life of people with physical and mental health conditions via an integrated care approach. This pilot study evaluates the impact of the intervention on self-perceived health (SPH), quality of life (QoL), active coping behaviour, and mental and social functioning.

Methods: Data were analysed from N = 457 participants who had been referred to the intervention by their general practitioner (mean age 48.

Cationic pH-sensitive liposome-based subunit tuberculosis vaccine induces protection in mice challenged with Mycobacterium tuberculosis.

Tuberculosis (TB) has been and still is a global emergency for centuries. Prevention of disease through vaccination would have a major impact on disease prevalence, but the only available current vaccine, BCG, has insufficient impact. In this article, a novel subunit vaccine against TB was developed, using the Ag85B-ESAT6-Rv2034 fusion antigen, two adjuvants - CpG and MPLA, and a cationic pH-sensitive liposome as a delivery system, representing a new TB vaccine delivery strategy not previously reported for TB.

Metabolic blood profile and response to treatment with the pyruvate kinase activator mitapivat in patients with sickle cell disease.

Mitapivat is an investigational, oral, small-molecule allosteric activator of pyruvate kinase (PK). PK is a regulatory glycolytic enzyme that is key in providing the red blood cell (RBC) with sufficient amounts of adenosine triphosphate (ATP). In sickle cell disease (SCD), decreased 2,3-DPG levels increase the oxygen affinity of hemoglobin, thereby preventing deoxygenation and polymerization of sickle hemoglobin.

Confined placental mosaicism: Distribution of chromosomally abnormal cells over the term placenta.

Objective: Non-invasive prenatal testing (NIPT) investigates placental DNA and may detect confined placental mosaicism (CPM). The aim of this study was to confirm CPM in the term placenta in cases with abnormal NIPT but normal follow-up cytogenetic studies of fetus and mother. Additionally we examined the distribution of abnormal cells over the placenta.

The natural history of progressive myoclonus ataxia.

Progressive myoclonus ataxia (PMA) is a rare clinical syndrome characterized by the presence of progressive myoclonus and ataxia, and can be accompanied by mild cognitive impairment and infrequent epileptic seizures. This is the first study to describe the natural history of PMA and identify clinical, electrophysiological, and genetic features explaining the variability in disease progression. A Dutch cohort of consecutive patients meeting the criteria of the refined definition of PMA was included.

Longitudinal soluble marker profiles reveal strong association between cytokine storms resulting from macrophage activation and disease severity in COVID-19 disease.

SARS-CoV2 infection results in a range of disease severities, but the underlying differential pathogenesis is still not completely understood. At presentation it remains difficult to estimate and predict severity, in particular, identify individuals at greatest risk of progression towards the most severe disease-states. Here we used advanced models with circulating serum analytes as variables in combination with daily assessment of disease severity using the SCODA-score, not only at single time points but also during the course of disease, to correlate analyte levels and disease severity.

Gonococcal OMVs induce epithelial cell mitophagy in a dual PorB-dependent manner to enhance intracellular survival.

Outer membrane vesicles (OMVs) are nanometer-sized membrane blebs secreted by all Gram-negative bacteria to facilitate bacterial communication and modulate the external environment, including in the context of host-microbe interactions. releases OMVs during interactions with epithelial cells; however, beneficial functional activities for these OMVs have not yet been demonstrated. Our recent study shows that gonococcal OMVs are endocytosed by epithelial cells and subsequently induce mitophagy through a dual PorB-dependent mechanism.

DNA Nanoparticle Based 2D Biointerface to Study the Effect of Dynamic RGD Presentation on Stem Cell Adhesion and Migration.

The native extracellular matrix (ECM) undergoes constant remodeling, where adhesive ligand presentation changes over time and in space to control stem cell function. As such, it is of interest to develop 2D biointerfaces able to study these complex ligand stem-cell interactions. In this study, a novel dynamic bio interface based on DNA hybridization is developed, which can be employed to control ligand display kinetics and used to study dynamic cell-ligand interaction.
