We present a clinical case in occupational health nursing where the worker was showing symptoms of stress caused by a change of residence and related factors at work. A nursing assessment was made following Leininger's theory of Care Diversity and Universality and Sunrise Model, considered suitable for the case. After the assessment, it was determined that the factors associated with the migratory event triggered the reported symptoms, and a care plan was drawn up with monthly telephone contact follow-up and reassessment at 3months...

Boswellia sacra, a frankincense producing endemic tree, has been well known for its cultural, religious and economic values. However, the tree has been least explored for the associated microsymbiota in the rhizosphere. The current study elucidates the fungal and bacterial communities of the rhizospheric regions of the wild and cultivated B. sacra tree populations through next generation sequencing. The sequence analysis showed the existence of 1006±8.9 and 60.6±3.1 operational taxonomic unit (OTUs) for bacterial and fungal communities respectively...

BACKGROUND: People working with pigs are at elevated risk of harboring methicillin resistant S. aureus (MRSA) in their nose, which is attributable to occupational exposure to animals harboring livestock adapted S. aureus. To obtain insight into the biological nature of occupationally related nasal culture positivity, we conducted a longitudinal study of 66 swine veterinarians in the USA. METHODS: The study cohort resided in 15 US states and worked predominantly with swine...

Type-1 Diabetes (T1D) is a devastating autoimmune disorder which results in the destruction of beta cells within the pancreas. A promising treatment strategy for T1D is the replacement of the lost beta cell mass through implantation of immune-isolated microencapsulated islets referred to as the bioartificial pancreas. The goal of this approach is to restore blood glucose regulation and prevent the long-term comorbidities of T1D without the need for immunosuppressants. A major requirement in the quest to achieve this goal is to address the oxygen needs of islet cells...

Respiratory diseases in ruminants have a significantly negative impact on the worldwide economy. The bacterium Mannheimia haemolytica is involved in pneumonic infections in bovine and ovine. In gram-negative bacteria, six secretion systems related to the colonization process and host tissue damage have been reported. In addition, in the last two decades, the production of outer membrane vesicles has been studied as a different bacterial strategy to release virulence factors, such as exotoxins, lipopolysaccharides, and proteases...

It has been widely accepted that cell culture in two-dimensional (2D) conditions may not be able to represent growth in three-dimensional (3D) conditions. Systematic comparisons between 2D and 3D cell cultures are needed to appropriately use the existing 2D results. In this work, we conducted a comparative study between 2D and 3D cell cultures of MC3T3-E1 using the same type of material (a mixture of silk fibroin (SF) and chitosan (CS)). Our results showed 3D SF/CS scaffold exhibited different effects on cell culture compared with the 2D cases...

Fundamental understanding and characterization of neural response to substrate topography is essential in the development of next generation biomaterials for nerve repair. Aerogels are a new class of materials with great potential as a biomaterial. In this work, we examine the extension of neurites by PC12 cells plated on matrigel-coated and collagen-coated mesoporous aerogel surfaces. We have successfully established the methodology for adhesion and growth of PC12 cells on polyurea crosslinked silica aerogels...

BACKGROUND: Surveys in the United States and Europe have shown a plateau of new HIV cases, with certain regions and populations disproportionately affected by the disease. Ethnic minority women and socioeconomically disadvantaged groups are disproportionately affected by HIV. Previous reviews have focused on prevention interventions targeting ethnic minority men who have sex with men, have not accounted for socioeconomic status, or have included only interventions carried out in clinical settings...

Recent advances in cell-based assays have involved the integration of single-cell analyses and microfluidics technology to facilitate both high-content and high-throughput applications. These technical advances have yielded large datasets with single-cell resolution, and have given rise to the study of cell population dynamics, but statistical analyses of these populations and their properties have received much less attention, particularly for cells cultured in microfluidic systems. The objective of this study was to perform statistical analyses using Pittsburgh Heterogeneity Indices (PHIs) to understand the heterogeneity and evolution of cell population demographics on datasets generated from a microfluidic single-cell-resolution cell-based assay...

Embryonic stem cell (ESC) differentiation can be used to model development and to produce transplantable cells of the desired phenotype. ESCs can reproducibly generate retinal cells but the derivation of photoreceptor precursors is variable and depends on an array of exogenous factors and intrinsic cell-cell interactions. In this work, we have defined the use of exogenous signaling factors, dissociation, and adherent versus 3-dimensional (3D) conditions on the derivation of retinal cells from pluripotent mouse ESCs...

AIMS/HYPOTHESIS: Increasing brown adipose tissue (BAT) activity is a possible therapeutic strategy to increase energy expenditure and glucose and lipid clearance to ameliorate obesity and associated comorbidities. The thiazolidinedione (TZD) class of glucose-lowering drugs increase BAT browning in preclinical experimental models but whether these actions extend to humans in vivo is unknown. The aim of this study was to determine the effect of pioglitazone treatment on adipocyte browning and adaptive thermogenesis in humans...

BACKGROUND: Surface functionalization of orthopedic implants with pharmaceutically active agents is a modern approach to enhance osseointegration in systemically altered bone. A local release of strontium, a verified bone building therapeutic agent, at the fracture site would diminish side effects, which could occur otherwise by oral administration. Strontium surface functionalization of specially designed titanium-niobium (Ti-40Nb) implant alloy would provide an advanced implant system that is mechanically adapted to altered bone with the ability to stimulate bone formation...

Non-enveloped viruses protect their genomes by packaging them into an outer shell or capsid of virus-encoded proteins. Packaging and capsid assembly in RNA viruses can involve interactions between capsid proteins and secondary structures in the viral genome as exemplified by the RNA bacteriophage MS2 and as proposed for other RNA viruses of plants, animals and human. In the picornavirus family of non-enveloped RNA viruses, the requirements for genome packaging remain poorly understood. Here we show a novel and simple approach to identify predicted RNA secondary structures involved in genome packaging in the picornavirus foot-and-mouth disease virus (FMDV)...

Leishmanioses are neglected diseases and the parasite Leishmania survives and proliferates within mononuclear phagocytes, particularly macrophages. In vitro studies of the immunology and cell biology of leishmaniosis are performed in murine peritoneum and bone marrow macrophages and immortalized cell lines despite the normal and injured tissue-specific heterogeneity of macrophages. In this work we established an ex vivo methodology to culture lesional cells from BALB/c mice infected with L. amazonensis. The cells were successfully isolated from footpad skin lesions and those exhibiting macrophage morphology were maintained in long-term culture (12 days), while the small number of lymphocytes, polymorphonuclear and unidentified cells died after one day of culture...

Epidemiological studies have consistently shown associations between elevated concentrations of urban particulate matter (UPM) air pollution and exacerbations of asthma and COPD, which are both associated with viral respiratory infections. The effects of urban PM on dendritic cell (DC) stimulated CD4 T lymphocytes have been investigated previously, however little work has focused on CD8 T lymphocyte responses despite their importance in anti-viral immunity. To address this, we examined the effects of UPM on DC-stimulated naïve CD8 T cell responses...
