Central Nervous System Opportunistic Infections
Semin Neurol 2019; 39: 383-390 DOI: 10.1055/s-0039-1687842Opportunistic infections of the central nervous system are classically associated with immunosuppression arising from infection with human immunodeficiency virus and with various hematologic malignancies. However, over the past few years, they are increasingly associated with transplantation and various immunosuppressive treatments used to treat autoimmune diseases. They cause significant morbidity and mortality and remain a diagnostic challenge due to the absence of typical signs and symptoms of infection and mimicry by various noninfectious causes. The pathogens a...

A Review of Mathematical Models for Muscular Dystrophy: A Systems Biology Approach
Discussion With new developments in computational power and data availability, a growing amount of research is using a systems biology approach to understand pathogenesis and progression of disease. Effective and integrated in vitro and in silico models could inform biological phenomena, even without the need of a living subject. For instance, over the last few decades, collagen hydrogel with muscle derived cells (CHMDCs) have promised to revolutionize in vitro experiments and tissue engineering. For CHMDCs to reach the envisioned use, verification by use of mathematical simulations are needed. Recently while examining sha...

A novel microgripper hybrid driven by a piezoelectric stack actuator and piezoelectric cantilever actuators
In this study, a novel microgripper hybrid driven by a PSA and two PCAs is proposed, which can be a better solution for the issue, compared with the previous microgripper using PSA-driven multi-stages displacement amplification mechanism(DAM) or using longer and narrower PCAs. A compact one-stage orthogonalDAM is proposed for the PSA in the microgripper, which can enlarge the grasping stroke and realize parallel grasping movement. The proposed orthogonalDAM is a triangulation amplification-based mechanism with undetermined structural parameters. Bidirectional symmetric input forces/displacements are not required in the pro...

Neuropharmacologic Approaches to Restore the Brain’s Microenvironment
Abstract Maintaining the central nervous system microenvironment after injury, infection, inflammatory and degenerative diseases is contingent upon adequate control of glial homeostatic functions. Disease is caused by microbial, environmental and endogenous factors that compromise ongoing nervous system functions. The final result is neuronal injury, dropout and nerve connection loss, and these underlie the pathobiology of Alzheimer’s and Parkinson’s disease, amyotrophic lateral sclerosis, stroke, and bacterial, parasitic and viral infections. However, what promotes disease are homeostatic changes in the brain...

Environmental Pollution: An Under-recognized Threat to Children’s Health, Especially in Low- and Middle-Income Countries
Conclusions Patterns of disease are changing rapidly in LMICs. Pollution-related chronic diseases are becoming more common. This shift presents a particular problem for children, who are proportionately more heavily exposed than are adults to environmental pollutants and for whom these exposures are especially dangerous. Better quantification of environmental exposures and stepped-up efforts to understand how to prevent exposures that cause disease are needed in LMICs and around the globe. To confront the global problem of disease caused by pollution, improved programs of public health monitoring and environmental protecti...

Post-translational Protein Modifications of Rare and Unconventional Types: Implications in Functions and Diseases.
Abstract Protein post-translational modification (PTM) occurs following their biosynthesis and is a key cellular event that defines their ultimate functional properties. It is an important control mechanism for display of biological functions of proteins often in a profound manner. It may switch on or off a protein's function. Several studies have been conducted to understand their mechanisms, physiological pathways and functional properties. PTMs have been shown to alter structural, conformational and physicochemical properties of proteins. So far a variety of protein modifications have been detected in physiolog...

Chagas disease as a cause of heart failure and ventricular arrhythmias in patients long removed from endemic areas: an emerging problem in Europe
We report two examples of Chagas cardiomyopathy in South American women permanently residing in Italy for more than 20 years, presenting with cardiac manifestations ranging from left ventricular dysfunction and heart failure to isolated ventricular arrhythmias. The present review emphasizes that Chagas disease should be considered as a potential diagnosis in patients from endemic areas presenting with ‘idiopathic’ cardiac manifestations, even when long removed from their country of origin, with potential implications for treatment and control of Chagas disease transmission.

High-salt diet could protect against invading microbes
Most people consume more salt than they need and therefore have a higher risk of heart disease and stroke, which are the two leading causes of death worldwide. But a new study reveals that dietary salt could have a biological advantage: Defending the body against invading microbes. A high-salt diet increased sodium accumulation in the skin of mice, thereby boosting their immune response to a skin-infecting parasite.
