Extent and Nature of Television Food and Nonalcoholic Beverage Marketing in 9 Asian Countries: Cross-Sectional Study Using a Harmonized Approach.

Background: Rising childhood obesity rates in Asia are adding risk for the future adult burden of obesity and noncommunicable diseases. Weak policies across most Asian countries enable unrestricted marketing of obesogenic foods and beverages to children. Television is the common medium for food marketing to reach this audience.

Co-imaging of RelA and c-Rel reveals features of NF-κB signaling for ligand discrimination.

Individual cell sensing of external cues has evolved through the temporal patterns in signaling. Since nuclear factor κB (NF-κB) signaling dynamics have been examined using a single subunit, RelA, it remains unclear whether more information might be transmitted via other subunits. Using NF-κB double-knockin reporter mice, we monitored both canonical NF-κB subunits, RelA and c-Rel, simultaneously in single macrophages by quantitative live-cell imaging.

Prehospital Management of Penetrating Neck Injuries: An Evaluation of Practice.

Objective: Penetrating neck injuries (PNIs) can occur at multiple anatomic sites and involve airway, nerve, vascular, and gastrointestinal structures. They pose a unique challenge to clinicians, especially in the prehospital setting. Published guidance on the prehospital management of PNIs is limited, and there is no review of the current prehospital practice.

Dissection of MKK6 and p38 Signaling Using Light-Activated Protein Kinases.

Stress-activated signaling pathways orchestrate cellular behaviors and fates. Studying the precise role(s) of stress-activated protein kinases is challenging, because stress conditions induce adaptation and impose selection pressure. To meet this challenge, we have applied an optogenetic system with a single plasmid to express light-activated p38α or its upstream activator, MKK6, in conjunction with live-cell fluorescence microscopy.

Cooperative environmental governance in urban South Asia: implications for municipal waste management and waste-to-energy.

This paper critically discusses the importance of cooperative environmental governance (CEG) for efficient waste management and waste-to-energy (WtE) generation in the context of growing urban South Asia. Focusing on Bangladesh, India and Pakistan experiences, the paper reveals that even though much progress has been done in the urbanisation in the selected countries, the process of waste management (mainly municipal solid waste) has not been effective due to low level of local inclusion. As a result, the WtE generation potential has not been realised to its fullest.

On the inference of ERK signaling dynamics from protein biosensor measurements.

The extracellular signal-regulated kinase (ERK) signaling pathway plays prominent roles in cell growth, proliferation, and differentiation. ERK signaling is dynamic, involving phosphorylation/dephosphorylation, nucleocytoplasmic shuttling, and interactions with scores of protein substrates in the cytosol and in the nucleus. Live-cell fluorescence microscopy using genetically encoded ERK biosensors offers the potential to infer those dynamics in individual cells.

Double knockin mice show NF-κB trajectories in immune signaling and aging.

In vitro studies suggest that mapping the spatiotemporal complexity of nuclear factor κB (NF-κB) signaling is essential to understanding its function. The lack of tools to directly monitor NF-κB proteins in vivo has hindered such efforts. Here, we introduce reporter mice with the endogenous RelA (p65) or c-Rel labeled with distinct fluorescent proteins and a double knockin with both subunits labeled.

Role of NS2 specific RNA binding and phosphorylation in liquid-liquid phase separation and virus assembly.

Liquid-liquid phase separation (LLPS) has assumed a prominent role in biological cell systems, where it underpins the formation of subcellular compartments necessary for cell function. We investigated the underlying mechanism of LLPS in virus infected cells, where virus inclusion bodies are formed by an RNA-binding phosphoprotein (NS2) of Bluetongue virus to serve as sites for subviral particle assembly and virus maturation. We show that NS2 undergoes LLPS that is dependent on protein phosphorylation and RNA-binding and that LLPS occurrence is accompanied by a change in protein secondary structure.

Iron and Folic Acid Supplementation in Pregnancy: Findings from the Baseline Assessment of a Maternal Nutrition Service Programme in Bangladesh.

Effective coverage of antenatal iron and folic acid (IFA) supplementation is important to prevent adverse maternal and newborn health outcomes. We interviewed 2572 women from two rural districts in Bangladesh who had a live birth in the preceding six months. We analysed the number of IFA tablets received and consumed during pregnancy and examined the factors influencing IFA consumption by multiple linear regression and user adherence-adjusted effective coverage of IFA (consuming ≥180 IFA tablets) by Poisson regression.

NF-κB, a culprit of both inflamm-ageing and declining immunity?

NF-κB is generally recognized as an important regulator of ageing, through its roles in cellular senescence and inflammatory pathways. Activated in virtually all cell-cell communication networks of the immune system, NF-κB is thought to affect age-related defects of both innate and adaptive immune cells, relevant to inflamm-ageing and declining adaptive immunity, respectively. Moreover, the family of NF-κB proteins that exist as heterodimers and homodimers exert their function beyond the immune system.

The anthropometric assessment of body composition and nutritional status in children aged 2-15 years: A cross-sectional study from three districts in Bangladesh.

Background: Early life nutrition plays a critical role in the development of better health and nutrition in adulthood. However, assessing the nutritional status of Bangladeshi children and adolescents through measurement of body composition using skinfold thickness is barely studied. The current study aims to determine children's body composition and nutritional status, and contributing factors among children aged 2 to 15 years in the northern part of Bangladesh.

A Meta-analysis of Clinical Trials Evaluating the Impact of Bivalirudin-based Anticoagulation for Primary Percutaneous Coronary on Long-Term Mortality.

Bivalirudin and heparin are the principal anticoagulants used during primary percutaneous coronary intervention (PCI) for patients experiencing ST-elevation myocardial infarctions. Based on previous meta-analyses, bivalirudin improves 30-day mortality rates compared with heparin, especially when vascular access is predominantly femoral. However, no meta-analysis has yet reported whether this mortality benefit with bivalirudin persists beyond 30 days.

The Immunomodulatory CEA Cell Adhesion Molecule 6 (CEACAM6/CD66c) Is a Protein Receptor for the Influenza a Virus.

To establish a productive infection in host cells, viruses often use one or multiple host membrane glycoproteins as their receptors. For Influenza A virus (IAV) such a glycoprotein receptor has not been described, to date. Here we show that IAV is using the host membrane glycoprotein CD66c as a receptor for entry into human epithelial lung cells.

A meta-analysis of optimal medical therapy with or without percutaneous coronary intervention in patients with stable coronary artery disease.

Background: Whether percutaneous coronary intervention (PCI) improves clinical outcomes in patients with chronic angina and stable coronary artery disease (CAD) has been a continuing area of investigation for more than two decades. The recently reported results of the International Study of Comparative Health Effectiveness with Medical and Invasive Approaches, the largest prospective trial of optimal medical therapy (OMT) with or without myocardial revascularization, provides a unique opportunity to determine whether there is an incremental benefit of revascularization in stable CAD patients.

Methods: Scientific databases and websites were searched to find randomized clinical trials (RCTs).

Fatal Attraction: The Case of Toxic Soluble Dimers of Truncated PQBP-1 Mutants in X-Linked Intellectual Disability.

The frameshift mutants K192S and R153S, of the polyglutamine tract-binding protein 1 (PQBP-1), are stable intrinsically disordered proteins (IDPs). They are each associated with the severe cognitive disorder known as the Renpenning syndrome, a form of X-linked intellectual disability (XLID). Relative to the monomeric wild-type protein, these mutants are dimeric, contain more folded contents, and have higher thermal stabilities.

Minimizing Heterogeneity of Protein Samples for Metal Transporter Proteins Using SAXS and Metal Radioisotopes.

The scattering profiles at small angles, obtained after an X-ray beam is incident on biological samples (protein), are nowadays successfully used to obtain important structural information. Small angle X-ray scattering (SAXS) is now helpful in providing information about shape, conformation, and assembly state of molecules, besides macromolecular folding-unfolding, aggregation, and extended conformations. The article discusses here a protocol to identify those fractions of heterogeneous proteins that are rich in homogeneous samples, testified by proper conformation and protein activity.
