Heterozygosity for a 3-base pair deletion (ΔGAG) in TOR1A/torsinA is one of the most common causes of hereditary dystonia. In this review, we highlight current understanding of how this mutation causes disease from research spanning structural biochemistry, cell science, neurobiology, and several model organisms. We now know that homozygosity for ΔGAG has the same effects as Tor1a(KO) , implicating a partial loss of function mechanism in the ΔGAG/+ disease state. In addition, torsinA loss specifically affects neurons in mice, even though the gene is broadly expressed, apparently because of differential expression of homologous torsinB...

Microphysiological systems (organs-on-chips, tissue chips) are devices designed to recapitulate human physiology that could be used to better understand drug responses not easily addressed using other in vivo systems or in vitro animal models. Although still in development, initial results seem promising as tissue chips exhibit in vivo systems-like functional responses. The National Center for Advancing Translation Science (NCATS) identifies this technology as a potential tool that could improve the process of getting safer, more effective treatments to patients, and has led to the Tissue Chip Program, which aims to develop, integrate and validate major organ systems for testing...

Until recently, research in animal welfare science has mainly focused on negative experiences like pain and suffering, often neglecting the importance of assessing and promoting positive experiences. In rodents, specific facial expressions have been found to occur in situations thought to induce negatively valenced emotional states (e.g., pain, aggression and fear), but none have yet been identified for positive states. Thus, this study aimed to investigate if facial expressions indicative of positive emotional state are exhibited in rats...

Animal feeding is the most important economic component of beef production systems. Selection for feed efficiency has not been effective mainly due to difficult and high costs to obtain the phenotypes. The application of genomic selection using SNP can decrease the cost of animal evaluation as well as the generation interval. The objective of this study was to compare methods for genomic evaluation of feed efficiency traits using different cross-validation layouts in an experimental beef cattle population genotyped for a high-density SNP panel (BovineHD BeadChip assay 700k, Illumina Inc...

SIGNIFICANCE: Recent clinical evidence identified anemia to be correlated with severe complications of cardiovascular disease such as bleeding, thromboembolic events, stroke, hypertension, arrhythmias, as well as inflammation, particularly in elderly patients. The underlying mechanisms of these complications are largely unidentified. Recent Advances: Previously, red blood cells (RBCs) were considered exclusively as transporters of oxygen and nutrients to the tissues. More recent experimental evidence indicates that RBCs are important inter-organ communication systems with additional functions, including participation in control of systemic NO metabolism, redox regulation, blood rheology and viscosity...

Plastic surgery is transitioning from a fine craftsmanship to a regenerative science. In wound healing, the role of microorganisms is no longer considered to be just counteracting, but also promoting. Furthermore, host-microbe interactions are essential for numerous aspects of normal mammalian physiology, from metabolic activity to immune homeostasis. Each area of the human body hosts a unique microbial community, and the composition of microbiota is dependent on the host, age and the anatomical area, and it changes according to the characteristics of the microenvironment...

Exact cause of the metabolic syndrome [MS], a global epidemic, is still unclear. Man has same fundamental needs to live as animals but modern man's life-style compels him to acquire certainty of resources for all his needs in a complex social network. Today money has become the sole life essential need. Contrarily none of the animals needs to earn money. Brain is also an organ of the human body with a unique thought process to define logical actions to achieve a person's goals. This way life is a flow of desires followed by logical actions...

In 1872, Charles Darwin published The Expression of the Emotions in Man and Animals, in which he argued that mammals show emotion reliably in their faces. Since then, thousands of studies have confirmed the robustness of Darwin's argument in many fields, including linguistics, semiotics, social psychology, and computer science. More interestingly, several studies, including those of renowned psychologist Paul Ekman, demonstrated that basic emotions are, indeed, universal. Affectiva, a Massachusetts Institute of Technology spinoff located in Waltham, Massachusetts, builds a variety of products that harness the two main characteristics of facial expressions-robustness and universality-to measure and analyze emotional responses...

BACKGROUND: Recent research has identified an increased rate of mortality associated with fluid bolus therapy for severe sepsis and septic shock, but the mechanisms are still not well understood. Fluid resuscitation therapy administered for sepsis and septic shock targets restoration of the macro-circulation, but the pathogenesis of sepsis is complex and includes microcirculatory dysfunction. OBJECTIVE: The objective of the study is to systematically review data comparing the effects of different types of fluid resuscitation on the microcirculation in clinically relevant animal models of lipopolysaccharide-induced sepsis...

Nonunion remains the most impactful complication following ankle and hindfoot arthrodesis. Historically, surgeons have relied on autologous bone graft (ABG) to combat nonunion risk. Although effective, ABG remains limited in quantity, varies in quality, and can be associated with harvest site pain and morbidity. Use of alternative bone-stimulating agents, however, avoids harvesting an autograft, and provides a more predictable dose-response efficacy. This article highlights findings from basic science, animal, and human clinical research that led to the approval of Augment Bone Graft...

Stroke is not only a leading cause of mortality and morbidity worldwide it also disproportionally affects women. There are currently over 500,000 more women stroke survivors in the US than men, and elderly women bear the brunt of stroke-related disability. Stroke has dropped to the fifth leading cause of death in men, but remains the third in women. This review discusses sex differences in common stroke risk factors, the efficacy of stroke prevention therapies, acute treatment responses, and post-stroke recovery in clinical populations...

Growth and development are key characteristics of childhood and sensitive markers of health and adequate nutrition. The first 1000 days of life-conception through 24 months of age-represent a fundamental period for development and thus the prevention of childhood obesity and its adverse consequences is mandatory. There are many growth drivers during this complex phase of life, such as nutrition, genetic and epigenetic factors, and hormonal regulation. The challenge thus involves maximizing the potential for normal growth without increasing the risk of associated disorders...
