Blood circulation values in patients with cardiac resynchronization therapy during the first 6 months in different stimulated QRS complex duration classes

Twenty nine patients (10 — females, 19 — males) with obtained cardiac resynchronization therapy (CRT) treatment were examined at the department of ultrasound, clinical and instrumental diagnosis and minimally invasive technologies of SI «V.T. Zaitsev Institute of General and Emergency Surgery NAMS of Ukraine». Patients’ average age was 69±7 years. The frequency of ventricular rate of spontaneous and induced rhythm, systolic and diastolic blood pressure, left ventricular ejection fraction, end-diastolic and end-systolic volumes, interventricular septum, posterior wall thicknesses, left and right atriums, right ventricle sizes were evaluated before treatment, in the early postoperative period (the 3rd– 5th day) and 6 months after CRT-device implantation. Carefully executed CRT with high-quality selection of the electrode application point and adequate medical support can not only prevent the further extension, but also, in some cases, can shorten the duration of the extended baseline QRS complex with improving functional blood circulation values. CRT with high-quality selection of the electrode application point and adequate medical support is an effective treatment in patients with chronic heart failure

Усть-ишимская кость: минералогогеохимические свойства как источник палеонтологической, палеоантропологической и палеоэкологической информации

Ust-Ishim man was the representative of one of the ancestral groups of the Homo sapiens, Neanderthals and Denisovans. The first results of a comprehensive mineralogical and geochemical study of fossil bones using a wide range of physical, chemical and physico-chemical methods: thermal analysis, optical microscopy, scanning electron microscopy, atomic-force microscopy, nitrogen capillary condensation method, X-ray fluorescence analysis, ISP-MS, gas chromatography method, amino acid chromatography analysis’s, X-ray microprobe method, X-ray diffraction method, Raman and infrared spectroscopy, isotope spectrometry are presented in this article. The studied fragment of the skeleton is of higher preservation rate than the common bone detritus of this age and even the fossils of younger Pleistocene animals that allowed determining almost all its primary properties. The unique preservation presumably was provided by the favorable environment and a special way the Ust-Ishim man originally was buried. Results of study of the chemical and mineral composition of the bone fossils allowed a reconstruction of the Ust-Ishim man life history.Впервые проведено минералого-геохимическое исследование ископаемой кости с использованием широкого комплекса физических, физико-химических и химических методов: термического анализа, оптической, сканирующей электронной, сканирующей зондовой микроскопии, капиллярной конденсации азота, рентгенфлуоресцентного анализа, ИСП-МС, газовой хроматографии, рентгеноспектрального микрозондового анализа, рентгеновской дифракции, инфракрасной и КР спектроскопии, изотопной спектрометрии. Изученный нами фрагмент кости устьишимского человека на фоне костного детрита современных ему и даже значительно более молодых плейстоценовых промысловых животных характеризуется аномально высокой степенью сохранности практически по всем своим свойствам. Феномен столь аномальной сохранности можно объяснить тем, что устьишимский человек первоначально был захоронен либо в особом месте, либо особенным способом
