Adenoid Cystic Carcinoma of the Upper Trachea: A Rare Neoplasm

Journal of Clinical Imaging Science, 2013
Primary malignant tracheal tumors are not common and adenoid cystic carcinoma (ACC) of trachea is rare. We report an extremely rare case of ACC of proximal trachea, which was diagnosed in a 42-year-old male who presents with 6-month history of dyspnea ...

Complete mesocolic excision does not increase short-term complications in laparoscopic left-sided colectomies : a comparative retrospective single-center study [PDF]

, 2019
Background: Since the implementation of total mesorectal excision (TME) in rectal cancer surgery, oncological outcomes improved dramatically. With the technique of complete mesocolic excision (CME) with central vascular ligation (CVL), the same surgical ...

Issues of Chaos and Recurrence in Infinite Dimensions [PDF]

arXiv, 2009
Various issues with regard to chaos and recurrence in infinite dimensions are discussed. The doctrine we are trying to derive is that Sobolev spaces over bounded spatial domains do host chaos and recurrence, while Sobolev spaces over unbounded spatial domains are lack of chaos and recurrence. Local Sobolev spaces over unbounded spatial domains can host

Phyllodes Tumor of the Breast: Histopathologic Features, Differential Diagnosis, and Molecular/Genetic Updates.

Archives of Pathology & Laboratory Medicine, 2016
CONTEXT -Phyllodes tumor (PT) of the breast is a rare fibroepithelial neoplasm with risks of local recurrence and uncommon metastases. The classification proposed by the World Health Organization for PTs into benign, borderline, and malignant is based on

Electric Pulse Regulated MXene Based Nanozymes for Integrative Bioelectricity Immuno‐Cancer Therapy

Advanced Functional Materials, EarlyView.
MXenzyme‐mediated bioelectricity cancer therapy (MXenzyme‐BECT) enhances cancer cell death through irreversible depolarization, ion channel disruption, ROS generation, and immunogenic cell death. Computational simulations reveal the electrical mechanisms by which MXenzyme acts on single cells and support to predict treatment parameters. Next‐generation

Recurrence rates for observations of flows [PDF]

arXiv, 2011
We study Poincar\'e recurrence for flows and observations of flows. For Anosov flow, we prove that the recurrence rates are linked to the local dimension of the invariant measure. More generally, we give for the recurrence rates for the observation an upper bound depending on the push-forward measure.

Surgical management of extrafollicular variant of adenomatoid odontogenic tumor in the maxillary posterior region [PDF]

, 2019
Background. Adenomatoid odontogenic tumor (AOT) is a relatively uncommon benign neoplasm of odontogenic epithelial origin, accounting for less than 5% of odontogenic tumors. Case Report. The reported case describes morphological characteristics, clinical
