Assessing Surgical Extent in Endoscopic Sinus Surgery: A Scoping Review of Scoring Systems
International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Endoscopic sinus surgery (ESS) varies substantially in the extent of surgical dissection performed, even when described under the same procedural label. In chronic rhinosinusitis, this heterogeneity may influence postoperative outcomes, revision rates, and response to biologic therapies.

Hierarchical matrix preconditioners for the Oseen equations
, 2007 Hierarchical matrices provide a technique for the data-sparse approximation and matrix arithmetic of large, fully populated matrices. In particular, approximate inverses as well as approximate LU factorizations of finite element stiffness matrices may be

Animal Models and Experimental Medicine, EarlyView.Diabetes combined with ischemic stroke (DMIS) exacerbates brain infarct size and neuronal damage compared to nondiabetic ischemic stroke (IS). This study reveals that microRNA‐34a (miR‐34a) plays a key role in DMIS pathogenesis: miR‐34a directly targets and suppresses brain‐derived neurotrophic factor (BDNF) and Sine oculis homeobox 3 (SIX3), promoting

An inverse LU preconditioner based on the Sherman–Morrison formula
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria MatematicaAn approximate inverse LU preconditioner is constructed based on the Sherman–Morrison formula. Applying recursively that inversion formula a multiplicative decomposition of the inverse of a matrix is obtained.

Porcine kidney xenotransplantation: From primate models to clinical reality
Animal Models and Experimental Medicine, EarlyView.In the face of a critical shortage of human donor kidneys for end‐stage renal disease patients, porcine kidney xenotransplantation has emerged as a viable solution. This field has navigated major hurdles, including immune rejection, physiological incompatibilities, potential biomechanical differences and the risk of cross‐species infection. To overcome

Engraftment of sheep splenic lymphocytes into NBSGW mice and application in Brucella infection
Animal Models and Experimental Medicine, EarlyView.A sheep splenocyte‐reconstituted mouse model (Sh‐Spl mice) was established via intravenous injection of sheep splenic lymphocytes into immunodeficient mice to evaluate Brucella infection. Abstract Background The development of immune reconstituted xenograft mouse models has addressed the limitations imposed by interspecies immunological differences in ...

The Anatomical Record, EarlyView.Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...
