A novel high-throughput in-cell Western assay for the quantitative measurement of signaling dynamics in DNA damage signaling networks : cell decision processes in response to DNA double strand breaks
Following exposure to DNA damage, cells initiate a stress response involving multiple protein kinase signaling cascades. The DNA damage response results in one of several possible cell-fate decisions, or cellular responses: induction of cell-cycle arrest, initiation of DNA repair, activation of …

Quantitative measurement of epicardial adipose tissue and correlation with other markers for increased cardiovascular and metabolic risk in patients with long-term diabetes mellitus type 1 // Количествено измерване на епикардната мастна тъкан и корелация с други маркери за повишен сърдечно-съдов и метаболитен риск при пациенти с дългогодишен тип ЗД 1
Захарният диабет (ЗД) е едно от най-често срещаните метаболитни заболявания и се характеризира с нарушение на метаболизма на въглехидратите, протеините и липидите. Повишеното натрупване на висцерална мастна тъкан е рисков фактор за инсулинова резистентност, която може да намали инсулиновата …
