Diagnostic Utility of Ki‐67 Index on Cell Block Material for Grading Medullary Thyroid Carcinoma

Diagnostic Cytopathology, EarlyView.
ABSTRACT Introduction An international grading system for medullary thyroid carcinoma (IMTCGS) was established in 2022. High‐grade MTC is defined by the presence of one or more of the following features: mitotic index ≥ 5 per 2 mm2, Ki‐67 proliferative index ≥ 5%, or tumor necrosis.

Pricing options in illiquid markets: optimal systems, symmetry reductions and exact solutions

, 2010
We study a class of nonlinear pricing models which involves the feedback effect from the dynamic hedging strategies on the price of asset introduced by Sircar and Papanicolaou. We are first to study the case of a nonlinear demand function involved in the

Disseminated Histoplasmosis: An Unusual Finding at ROSE

Diagnostic Cytopathology, EarlyView.
ABSTRACT We describe an unusual case in which disseminated histoplasmosis was suspected at the time of of rapid on‐site assessment (ROSE) performed during endobronchial ultrasound‐guided transbronchial needle aspiration (EBUS‐TBNA). The patient was a renal transplant recipient with fever, mild anemia, bilateral lung infiltrates and mediastinal ...

Cytologic Findings in Esophageal Perforation: An Institutional Experience With Pleural Fluid Specimens

Diagnostic Cytopathology, EarlyView.
ABSTRACT Introduction Esophageal perforation (EP) is a rare but life‐threatening condition, and most cases are due to iatrogenic causes. The rest occur spontaneously, due to malignancies, or trauma. The mortality rates can approach 50%, and delayed diagnosis of EP exacerbates patient outcomes.

Focusing Revisited: an MN-dynamics Approach [PDF]

, 2002
The nonlinear Schr{\"o}dinger (NLS) equation is a ubiquitous example of an envelope wave equation for conservative, dispersive systems. We revisit here the problem of self-similar focusing of waves in the case of the focusing NLS equation through the ...

Cytomorphology and Molecular Profile of Hyalinizing Clear Cell Carcinoma of the Lung: A Case With Mucinous Differentiation

Diagnostic Cytopathology, EarlyView.
ABSTRACT Hyalinizing clear cell carcinoma (HCCC) of the lung is an exceedingly rare salivary gland‐type neoplasm with limited cytomorphologic description. We report a case highlighting these features. A 3 mm incidental left‐airway lesion enlarged to 7 mm over 5 months, prompting radial endobronchial ultrasound (EBUS)‐guided transbronchial biopsy. Touch

Spin in a variable magnetic field: the adiabatic approximation

, 1998
The problem of spin precession in a time-dependent magnetic field is considered in the adiabatic approximation where the field direction or the angular velocity of its rotation is changing slowly.
