Digitally reconstructed radiographs (DRRs) play a significant role in modern clinical radiation therapy. They are used to verify patient alignments during image guided therapies with 2D-3D image registration. The generation of DRRs can be implemented intuitively in O(N3) relying on direct volume rendering (DVR) methods, such as ray marching. This complexity imposes certain limitations on the rendering performance if high quality DRR images are needed. Those DRRs can be alternatively generated in the k-space using the central slice theorem in O(N2logN)...

Tuberculosis is one of the leading infections after renal transplant, particularly in developing countries where the incidence and prevalence in the general population are high. Diagnosis requires bacteriologic and histologic confirmation. Interactions among the antitubercular drugs and the immunosuppressive agents have to be considered while prescribing, and surveillance for adverse effects is required. Although rare, case reports are available on extrapulmonary tuberculosis in allograft recipients. Here, we present a 25-year-old kidney transplant recipient who was diagnosed with lymph node tuberculosis under uncommon circumstances but who had a good outcome...

OBJECTIVES: End-stage renal disease develops in a high percentage of patients with vasculitis, in whom kidney transplant has become a therapeutic option. However, limited data are available on the prognosis and outcomes after kidney transplant in these patients. We aimed to compare the long-term graft survival and graft function in 8 renal transplant recipients with vasculitis (granulomatosis with polyangiitis, microscopic polyangiitis, Goodpasture syndrome, and Henoch-Schonlein purpura) with the other kidney recipients at a single center...

Cells interact with biomaterials indirectly through extracellular matrix (ECM) proteins adsorbed onto their surface. Accordingly, it could be hypothesized that the surface proteomic signature of a biomaterial might determine its interaction with cells. Here, we present a surface proteomic approach to test this hypothesis in the specific case of biomaterial-epithelial cell interactions. In particular, we determined the surface proteomic signature of different biomaterials exposed to the ECM of epithelial cells (basal lamina)...

BACKGROUND: The sequence of Q, R, and S peaks (QRS) complex detection is a crucial procedure in electrocardiogram (ECG) processing and analysis. We propose a novel approach for QRS complex detection based on the deterministic finite automata with the addition of some constraints. This paper confirms that regular grammar is useful for extracting QRS complexes and interpreting normalized ECG signals. A QRS is assimilated to a pair of adjacent peaks which meet certain criteria of standard deviation and duration...

Multipotent mesenchymal stromal cells (MSC) derived from both the bone marrow and adipose tissue possess the ability to differentiate into multiple cell lineages, regulate the immune function by secreting numerous bioactive paracrine factors, and hold great potential in cell therapy and tissue engineering. When combined with three-dimensional (3D) scaffolds, MSC can be used for bone defect reconstruction and engineering. This protocol describes the isolation of bone marrow mesenchymal stromal cells (BMMSC) and adipose-tissue derived stem cells (ADSC) from rabbits for subsequent seeding on tissue-engineered 3D-printed scaffolds and transplantation into a rabbit-model with the goal of repairing large osseous mandibular defects (one quarter of the lower jaw is removed surgically)...

Sorghum is a major food staple in sub-Saharan Africa (SSA), but its production is constrained by the parasitic plant Striga that attaches to the roots of many cereals crops and causes severe stunting and loss of yield. Away from cultivated farmland, wild sorghum accessions grow as weedy plants and have shown remarkable immunity to Striga. We sought to determine the extent of the resistance to Striga in wild sorghum plants. Our screening strategy involved controlled laboratory assays of rhizotrons, where we artificially infected sorghum with Striga, as well as field experiments at three sites, where we grew sorghum with a natural Striga infestation...

Diabetes is a disease characterized by elevated uncontrolled glucose level. Hyperglycemia results in diabetic complication due to a reaction between sugar and amino acid of proteins to form advanced glycation endproducts (AGEs) in different tissues. Medicinal plants are considered as a great source of bioactive compounds that affect many ailments. In this regard; AGEs formation could be inhibited by many bioactive compounds isolated from medicinal plants. Viscum schimperi Engl. is a plant belongs to Loranthaceae and known for its antidiabetic activity...
