Biosimilární inzuliny jsou biologickými léky, jejichž účinek je podobný referenčním inzulinům. Průkaz bezpečnosti a účinnosti je hlavním požadavkem pro jejich klinické využití. Postupné zavedení do klinické praxe povede v budoucích letech zřejmě k většímu rozšíření, které si vyžádá dlouhodobé sledování i se zřetelem na ovlivnění glykemií a případné vedlejší účinky., Biosimilar insulins are biological drugs with the effect similar to reference insulins. Documented safety and efficacy are the main demand for their clinical utility. The subsequent introduction into clinical practice will be followed by more frequent use which will need longterm evaluation of their effect on glycemia and eventual side effects as well., and Jan Škrha
The Academy of Sciences of the Czech Republic (AS CR) established a new public research institution, the Institute of Biotechnology AS CR, v. v. i. The primary ambition of this new institute is to develop cutting-edge basic and oriented research on topics opening for diagnostic and therapeutic applicatons in human medicine. In particular, the institute was established to serve as a nucleation center of BIOCEV, the joined Biotech & Biomed Research Center of the Academy of Sciences with Charles University, to be built at Vestec near Prague by the year 2012 with the support of the European Regional Development Funds in frame of the Operational Program R&D for Innovation., Peter Šebo, -red-., and Tři otázky pro ředitele připravila -red-
To determine the role of postinspiratory inspiratory activity of the diaphragm in the biphasic ventilatory response to hypoxia in unanesthetized rats, we examined diaphragmatic activity at its peak (DI), at the end of expiration (DE), and ventilation in adult unanesthetized rats during poikilocapnic hypoxia (10 % O2) sustained for 20 min. Hypoxia induced an initial increase in ventilation followed by a consistent decline. Tidal volume (VT), frequency of breathing (fR), DI and DE at first increased, then VT and DE decreased, while fR and DI remained enhanced. Phasic activation of the diaphragm (DI - DE) increased significantly at 10, 15 and 20 min of hypoxia. These results indicate that 1) the ventilatory response of unanesthetized rats to sustained hypoxia has a typical biphasic character and 2) the increased end-expiratory activity of the diaphragm limits its phasic inspiratory activation, but this increase cannot explain the secondary decline in tidal volume and ventilation., H.

Cardiac resynchronization therapy is not commonly used in the early postoperative period in pati ents undergoing cardiac surgery who have left ventricular (LV) dysfunction and a history of heart failure. We performed a prospective randomized clinical trial to compare atrial synchronous right ventricular (DDD RV) and biventricular (DDD BIV) pacing within 72 hours after cardiac surgery in patients with an EF ≤ 35 %, a QRS interval longer than 120 msec and who had LV dyssynchrony detected by real-time three-dimensional echocardiography (RT3DE). Epicardial pacing was provided by a modified Medtronic INSYNC III pacemaker. An LV epicardial pacing lead was implanted on the latest activated segment of the LV based on RT3DE. The study included 18 patients with ischemic heart diseas e, with or without valvular heart disease (14 men, 4 women, average age 71 years). Patients undergoing DDD BIV pacing had a statistically significant greater CO and CI (CO 6.7±1.8 l/min, CI 3.4±0.7 l/min/m²) than patients undergoing DDD RV pacing (CO 5.5±1.4 l/min, CI 2.8±0.7 l/min/m²), p<0.001. DDD BIV paci ng in the early postoperative period after cardiac surgery corrects LV dyssynchrony and has better hemodynamic results than DDD RV pacing., F. Straka ...
