Neuronal Na+ /K+ -ATPase is responsible for the maintenance of ionic gradient across plasma membrane. In doing so, in a healthy brain, Na+ /K+ -ATPase activity accounts for nearly half of total brain energy consumption. The α3-subunit containing Na+ /K+ -ATPase expression is restricted to neurons. Heterozygous mutations within α3-subunit leads to Rapid-onset Dystonia Parkinsonism, Alternating Hemiplegia of Childhood and other neurological and neuropsychiatric disorders. Additionally, proteins such as α-synuclein, amyloid-β, and SOD1 whose aggregation is associated to neurodegenerative diseases directly bind and impair α3-Na+ /K+ -ATPase activity...

Reconstruction of the orbital rim and floor following tumor excision is traditionally performed with bone grafts, vascularized grafts, or free flaps. The authors describe a case of an osteosarcoma of the maxillary sinus and a second case of an ossifying fibroma of the orbital floor, both of which required reconstruction of the orbital floor and rim. In both of these cases, reconstruction of the orbital floor and rim was performed with a titanium implant whose anterior portion was bent inferiorly to recreate the orbital rim...

BACKGROUND: Most people with suicide ideation (SI) do not attempt suicide (SA). Understanding the transition from current/recent SI to SA is important for mental health care. Our objective was to identify characteristics that differentiate SA from 30-day SI among representative U.S. Army soldiers. METHODS: Using a unique case-control design, soldiers recently hospitalized for SA (n = 132) and representative soldiers from the same four communities (n = 10,193) were administered the same questionnaire...

Advances in molecular neuroanatomical tools have expanded the ability to map in detail connections of specific neuron subtypes in the context of behaviorally driven patterns of neuronal activity. Analysis of such data across the whole mouse brain, registered to a reference atlas, aids in understanding the functional organization of brain circuits related to behavior. A process is described to image mouse brain sections labeled with standard histochemical techniques, reconstruct those images into a whole brain image volume and register those images to the Allen Mouse Brain Common Coordinate Framework...

The 21st century is seeing a resurgence in the use of maggot therapy-using the physical and biochemical benefits of fly larvae to debride and heal chronic, problematic wounds. Maggots are repulsive to many people, and this could interfere with the acceptance of this modality. Before instituting a maggot therapy programme at our institution, we sought to better understand the psychological barriers that may exist among patients in the Tver region of Russia. Between 2014 and 2016, all patients with arterial insufficiency and trophic ulcers at City Clinical Hospital No...

Migration profile of helical blades differs from conventional screw design. Tip-apex distance (TAD) greater than 25mm is associated with early failure in hip screws. This study investigates the effect of a reduced TAD on helical blade fixation. Six pairs of human cadaveric femoral heads were used. Bone mineral density (BMD) was determined by pQCT. Local bone quality was evaluated by breakaway torque. Helical blades were implanted with TAD of 20mm (normal) and 6mm (reduced). Specimens were cyclically tested under progressively increasing physiologic loading at 2Hz with starting peak force of 1'000N, increasing by 0...

Strains of Staphylococcus aureus , and to a lesser extent other staphylococcal species, are a significant cause of morbidity and mortality. An important factor in the notoriety of these organisms stems from their frequent resistance to many antimicrobial agents used for chemotherapy. This review catalogues the variety of mobile genetic elements that have been identified in staphylococci, with a primary focus on those associated with the recruitment and spread of antimicrobial resistance genes. These include plasmids, transposable elements such as insertion sequences and transposons, and integrative elements including ICE and SCC elements...

Achieving fixation and fusion across the lumbosacral junction has been a challenge for spinal deformity surgeons ever since the development of instrumentation. The S2 alar-iliac (S2AI) trajectory has been introduced as a method of pelvic fixation to decrease strain on S1 screws. The S2AI screws differ in several ways from traditional iliac screws. The trajectory of these screws helps avoid the use of offset connectors due to the screws alignment with the proximal pedicle screw instrumentation. Current literature shows that S2AI screws are effective with low complication rates, but the path of these screws is intimately associated with major neural and vascular structures...

REVIEW
Ronald H L Li, Fern Tablin
Sepsis is the leading cause of critical illness and mortality in human beings and animals. Neutrophils are the primary effector cells of innate immunity during sepsis. Besides degranulation and phagocytosis, neutrophils also release neutrophil extracellular traps (NETs), composed of cell-free DNA, histones, and antimicrobial proteins. Although NETs have protective roles in the initial stages of sepsis, excessive NET formation has been found to induce thrombosis and multiple organ failure in murine sepsis models...

Autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia purpura (ITP) have been associated with B-cell lymphoproliferative disorders. Here, we review the epidemiology, pathogenesis, diagnosis, and treatment of these autoimmune disorders, specifically in the setting of B-cell malignancies. AIHA and ITP are classically associated with chronic lymphocytic leukemia (CLL) but have also been reported in plasmacytic and lymphoproliferative disorders. AIHA includes both warm AIHA and cold agglutinin disease, the latter of which is strongly associated with Waldenström macroglobulinemia...
