Incidentally Found Olfactory Schwannoma: A Rare Case Report
Clinical Medicine Insights: Case ReportsBackground: Olfactory nerve schwannomas are sporadic, benign neurogenic tumors arising from Schwann cells within the olfactory pathway. Their clinical presentation is typically nonspecific, and diagnosis often requires careful radiologic and ...

Molecular Oncology, EarlyView.Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

The International Journal of Biological Markers, 2004 The study purpose was to investigate the association of human papillomavirus (HPV) infection with prostate cancer. The presence and type of HPV DNA were investigated by polymerase chain reaction in the preservation fluid of 60 consecutive prostate core ...

The positivity of low-order explicit Runge-Kutta schemes applied in splitting methods
, 2003 Splitting methods are frequently used for the solution of large stiff initial value problems of ordinary differential equations with an additively split right-hand side function.

Molecular Oncology, EarlyView.A urine‐based digital PCR assay targeting two hotspot TERT promoter variants detected bladder cancer with high sensitivity and no false positives in this case–control cohort. The streamlined AbsoluteQ workflow outperformed Sanger sequencing and supports non‐invasive molecular testing for bladder cancer detection.

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining
Molecular Oncology, EarlyView.IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

Positivity-preserving and asymptotic preserving method for 2D Keller-Segal equations
Mathematics of Computation, 2017 We propose a semi-discrete scheme for 2D Keller-Segel equations based on a symmetrization reformation, which is equivalent to the convex splitting method and is free of any nonlinear solver. We show that, this new scheme is unconditionally stable as long as the initial condition does not exceed certain threshold, and it asymptotically preserves the ...

Interpreting and managing preservation fluids positive for Gram-negative bacteria
Purpose of review: Culturing preservation fluids of solid organs before transplantation is not a standardized procedure. In this review, we aim to describe the state-of-the-art of literature evidence in this debated setting with a special focus on Gram ...

Large Time Step Methods for Hyperbolic Conservation Laws [PDF]
, 2017 The HLL (Harten–Lax–van Leer) and HLLC (HLL–Contact) schemes are extended to LTS-HLL(C) schemes. The LTS-HLL-type schemes for scalar conservation laws are defined in the numerical viscosity, flux-difference splitting and wave propagation form, and TVD ...
