Myofibroblastoma of the breast mimicking carcinoma: a diagnostic challenge with a crucial role for histopathology and immunohistochemistry.

Myofibroblastoma is a rare mesenchymal tumour known for its benign nature but complex diagnostic pathway. A woman in her 40s presented with a painless breast mass, initially reported as a fibroadenoma on ultrasound mammography and as a benign to borderline phyllodes tumour on fine needle aspiration cytology. Contrast-enhanced CT was reported as carcinoma of the breast with Breast Imaging and Reporting Data System (BIRADS)-6.

Pass-Transistor-Enabled Split Input Voltage Level Shifter for Ultra-Low-Power Applications.

In modern ICs, sub-threshold voltage management plays a significant role due to its perspective on energy efficiency and speed performance. Level shifters (LSs) play a critical role in signal exchange among multiple voltage domains by ensuring signal integrity and the reliable operation of ICs. In this article, a Pass-Transistor-Enabled Split Input Voltage Level Shifter (PVLS) is designed for area, delay, and power-efficient applications with a wide voltage conversion range.

Recent Advances in the Clinical Translation of Small-Cell Lung Cancer Therapeutics.

Small-cell lung cancer (SCLC) is a recalcitrant form of cancer, representing 15% of lung cancer cases globally. SCLC is classified within the range of neuroendocrine pulmonary neoplasms, exhibiting shared morphologic, ultrastructural, immunohistochemical, and molecular genomic features. It is marked by rapid proliferation, a propensity for early metastasis, and an overall poor prognosis.

Case studies of different types of precipitation at Ny-Ålesund, Arctic.

Arctic precipitation plays a crucial role in shaping the surface mass balance of Arctic sea ice and has wide-ranging impacts on local climate, ecosystems, and global sea level dynamics. With the Arctic undergoing warming trends, historical data and climate models indicate a shift from primarily snowfall to a rise in liquid and mixed forms of precipitation. This study tried to explain the microphysical characteristics and atmospheric conditions associated with different forms of precipitation and their transitions.

Two case reports of biliary stent infections by extensively drug-resistant Escherichia coli carrying bla at a tertiary-care hospital in West Bengal, India.

Background: Rising antimicrobial resistance (AMR) is an acute public health emergency impeding the clinical efficacy of surgical interventions. Biliary stent placement is one of the routine surgical procedures that rarely lead to infections that are empirically managed by broad-spectrum β-lactams and fluoroquinolones. Critical priority pathogens, such as carbapenem-resistant Escherichia coli challenge treatment outcomes and infection prevention.
