    Dose limitation is one of the vital principles in radiation protection regulation. The use of that Low-dose chest CT can be a screening method of choice for early detection of pulmonary cancer

    The purpose of our study is to show the value of ECG gated 64-MDCT as an non - invasive and reliable method for simultaneous assessment of coronary arteries as part of the aortic root evaluation. Methods and Materials. From February 2009 until March 2010 we performed 46 ECG - gated, 64 MDCT examinations to confirm a diagnosis of suspected aorta ascendens dissection . A transthoracic (TTE) and/or transesophageal (TEE) echocardiography was initially performed in all patients ( mostly TEE) Patients (pts) with arrhythmia and non-stable haemodynamic conditions were excluded. All MDCT scans were performed with retrospectively ECG gated technique (0,625mm slice thickness). Premedicaton with i.v. betaBlocker (propranolol) was administrated in all with heart rate> 70 bpm

    Modification of the standard 7-day Ovsynch protocol to increase the luteolytic and synchronization risks in dairy cows

    We hypothesized that a single dose of PGF2Ξ± belatedly injected on day 8 after GnRH-1 in cows receiving a 7-day Ovsynch-56 protocol (GnRH – 7 days – PGF2Ξ± – 56h – GnRH – 16h – timed AI) will increase the proportion of cows with complete luteolysis. At day 35Β±3 postpartum, 70 lactating Holstein cows from one herd were scored for body condition and pre-synchronized with PGF2Ξ± and GnRH (3 days apart) and 7 days later submitted to an Ovsynch-56 protocol for first AI after random assignment to two treatments: (1) OV-7 (n=35) with an injection of PGF2Ξ± either on day 7; or (2) OV-8 (n=35) on day 8 after G1, respectively. Blood was collected before the first PGF2Ξ±, at day 7 and day 8 in OV-7 and OV-8, respectively, at AI and at 7 days after AI to assess progesterone concentration. Ten cows were classified as acyclic and were excluded from the analysis resulting in 60 cows (OV-8, n=27; OV-7, n=33). In total, more (P=0.01) OV-8 cows and more (P=0.04) primiparous OV-8 cows had complete luteolysis compared with their OV-7 herd mates. In addition, more (P=0.008) OV-8 cows with BCS<2.75 had complete luteolysis compared with their OV-7 herd mates, whereas no difference was observed between treatments among cows with BCS β‰₯2.75. In conclusion, delaying the application of PGF2Ξ± by 1 day reduced the percentage of primiparous cows and cows with poorer BCS having incomplete luteal regression at the time of AI
