Published: January 2025

Purpose Of Review: Hot phases are a challenging clinical presentation in arrhythmogenic cardiomyopathy (ACM), marked by acute chest pain and elevated cardiac troponins in the absence of obstructive coronary disease. These episodes manifest as myocarditis and primarily affect young patients, contributing to a heightened risk of life-threatening arrhythmias and potential disease progression. This review aims to synthesize recent research on the pathophysiology, diagnostic challenges, and therapeutic management of hot phases in ACM.

Recent Findings: Hot phases have been linked to genetic mutations, particularly in desmosomal proteins such as Desmoplakin (DSP). Diagnostic challenges include differentiating hot phases from isolated acute myocarditis, through identification of red flags and a multimodal approach, including CMR, FDG-PET, endomyocardial biopsy and genetic testing. Emerging therapies, such as immunosuppressive and anti-inflammatory treatments, show promise in managing hot-phase episodes. Hot phases in ACM present a significant risk for arrhythmias and disease progression, necessitating a comprehensive diagnostic and therapeutic management. A multimodal diagnostic approach is essential for accurate diagnosis, but further research is needed to refine these strategies and improve prognosis for affected patients.

Evaluation of anion exchange resin for sorption of selenium (IV) from aqueous solutions.

BMC Chem

January 2025

Nuclear Chemistry Department, Hot Laboratories Center, Egyptian Atomic Energy Authority, P.O. 13759, Cairo, Egypt.

In this work, selenium (IV) ions were adsorbed from aqueous solutions by the strongly basic anion exchange resin Amberlite IRA-400. The morphology of the resin before and after Se(IV) sorption was investigated using different techniques such as energy dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). To determine the ideal sorption conditions, a batch approach was used to examine the variables affecting Se(IV) sorption performance, including pH, shaking time, adsorbent dosage, initial metal ion concentration, and temperature.

Purpose Of Review: To summarize the available data on the use of immunosuppression therapies for the management of hot phases of disease and recurrent myocarditis in patients with desmoplakin cardiomyopathy (DSP-CMP).

Recent Findings: Occurrence of myocarditis episodes has been associated with worsening of outcomes in DSP-CMP. Multiple case reports and small case series have described potential benefit in using anti-inflammatory and immunosuppressive medications for the treatment of those episodes.

The influence of temperature induced changes in the composition of MFGM on membrane phase transition and nanomechanical properties.

Biomimetic membrane was investigated as model systems to mimic the structure of milk fat globule membrane (MFGM) and to study the effects of thermal processing-induced changes in MFGM fractions on membrane morphology and physical properties. Molecular docking was utilized to screen xanthine oxidase (XO) as the MFGM protein most likely to bind to phospholipid molecules on MFGM. Fluorescence spectroscopy verified that XO formed stable complexes with DOPE, DPPC, and PS 18:0-18:1, with the strongest binding to DOPE.
