Technical recommendations for implementation of Volumetric Modulated Arc Therapy and Helical Tomotherapy Total Body Irradiation.

As a component of myeloablative conditioning before allogeneic hematopoietic stem cell transplantation (HSCT), Total Body Irradiation (TBI) is employed in radiotherapy centers all over the world. In recent and coming years, many centers are changing their technical setup from a conventional TBI technique to multi-isocenter conformal arc therapy techniques such as Volumetric Modulated Arc Therapy (VMAT) or Helical Tomotherapy (HT). These techniques allow better homogeneity and control of the target prescription dose, and provide more freedom for individualized organ-at-risk sparing.

Critical roles of outer membrane protein B (OmpB) in the tick host.

is a pathogen of public health concern and transmitted by the Gulf Coast tick, . Rickettsiae are obligate intracellular bacteria that enter and replicate in diverse host cells. Rickettsial outer membrane protein B (OmpB) functions in bacterial adhesion, invasion, and avoidance of cell-autonomous immunity in mammalian cell infection, but the function of OmpB in arthropod infection is unknown.

A patatin-like phospholipase mediates Rickettsia parkeri escape from host membranes.

Rickettsia species of the spotted fever group are arthropod-borne obligate intracellular bacteria that can cause mild to severe human disease. These bacteria invade host cells, replicate in the cell cytosol, and spread from cell to cell. To access the host cytosol and avoid immune detection, they escape membrane-bound vacuoles by expressing factors that disrupt host membranes.

ASB4 modulates central melanocortinergic neurons and calcitonin signaling to control satiety and glucose homeostasis.

Variants in the gene encoding ankyrin repeat and SOCS box-containing 4 () are linked to human obesity. Here, we characterized the pathways underlying the metabolic functions of ASB4. Hypothalamic expression was suppressed by fasting in wild-type mice but not in mice deficient in , which encodes Agouti-related protein (AgRP), an appetite-stimulating hormone, suggesting that ASB4 is a negative target of AgRP.

Periodontal Disease Augments Cardiovascular Disease Risk Biomarkers in Rheumatoid Arthritis.

Objectives: Periodontal disease (PD) and rheumatoid arthritis (RA) are known chronic conditions with sustained inflammation leading to osteolysis. Cardiovascular diseases (CVD) are frequent comorbidities that may arise from sustained inflammation associated with both PD and RA. In order to determine CVD risk, alterations at the molecular level need to be identified.
