Article Synopsis
  • - The study investigates the ECG characteristics of 103 acromegaly patients to assess the risk of cardiovascular complications and life expectancy, highlighting the significance of the Tp-e interval and its ratios as indicators of ventricular arrhythmia risk.
  • - Results show that patients with both baseline and current ECGs experienced a decrease in heart rate, QRS duration, and several arrhythmia parameters, which were similarly affected regardless of whether the patients were in active or remission stages of the disease.
  • - The conclusion emphasizes that treatment leads to improved ventricular arrhythmia parameters in acromegaly patients, which correlates with a significant reduction in IGF-1 levels, even in those with ongoing active disease.

Papain (aka C1A) family proteases, including bromelain enzymes, are widespread across the plant kingdom and play critical regulatory functions in protein turnover during development. The proteolytic activity exhibited by papain family proteases has led to their increased usage for a wide range of cosmetic, therapeutic, and medicinal purposes. Bromelain enzymes, or bromelains in short, are members of the papain family that are specific to the bromeliad plant family.

Article Synopsis
  • Mutations can lead to congenital arhinia (not having a nose) and a disease called FSHD2, which affects muscles.
  • In FSHD2, a protein called SMCHD1 usually helps keep a harmful gene called DUX4 under control, but when SMCHD1 is missing, DUX4 starts to cause problems in muscle cells.
  • Research shows that when stem cells from arhinia and FSHD2 patients are changed into nose precursor cells, they produce too much DUX4 and can die, with environmental factors like a herpesvirus infection making the problem worse.
