This article brings the biomechanical analysis of sport--Nordic walking--for patients with osteoporotic fractured vertebrae and shows that it is suitable for them. Based on the biomechanical model of skeletal load we have developed a method of walking movement for patients, different from the method of walking movement…

OBJECTIVES: The purpose of this study is to review a single-institutional experience gained over one decade, to assess late neuropsychological outcome in patients as well as to determine Norwood operation risk factors that are related to patient and procedure and influence these results. BACKGROUND: The reports of fir…

The aim of the present study was to define more accurately the necessary health care in patients with the primary Sjogren's syndrome and to compare it to those necessary for patients with another autoimmune disease--rheumatoid arthritis without a concomitant Sjogren's syndrome (Tab. 1, Ref. 5).

The article brings a biomechanical analysis of the determination of the position of gravity centre of trainee in plane, both graphically and by calculation. The importance of determining the position of the gravity centre in different postures of a trainee should not be underestimated, as it belongs to the basic princi…

The authors have gained their experience in psychostereotactic operations during the past 50 years. The operations were indicated in psychiatric patients on the basis of their clinical pictures. The results gained in operations of the hypothalamus, limbic system and neocortical structures of the brain were logically an…

OBJECTIVES: To evaluate the efficacy and safety of cryoablation compared with the radiofrequency (RF) method in the treatment of typical atrial flutter (AFL). METHODS: 12 patients with typical counterclockwise AFL underwent cryoablation of the cavotricuspid isthmus. Cryoablation was performed with a 9F catheter with a…

Most of medical journals now has it's electronic version, available over public networks. Although there are parallel printed and electronic versions, and one other form need not to be simultaneously published. Electronic version of a journal can be published a few weeks before the printed form and must not has identic…

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) belong to most frequently used drugs worldwide. NSAIDs belong to the family of drugs that represent the biggest drug risk as to the number of adverse drug reactions (ADRs), as well as to the number of deregistered drugs. METHODS: We analysed the whole consumpt…

Broad absorption signatures from alkali metals, such as the sodium (Na I) and potassium (K I) resonance doublets, have long been predicted in the optical atmospheric spectra of cloud-free irradiated gas giant exoplanets. However, observations have revealed only the narrow cores of these features rather than the full pr…

During routine anatomy dissection classes for undergraduate medical students, an unilateral case of superficial ulnar artery (SUA) in a 75-year-old male human cadaver arosing from the third part of the right axillary artery at the junction of the two median nerve roots was observed. In the hand, the SUA coursed over th…

BACKGROUND: The presence of dental caries impacts on children's daily lives, particularly among those living in deprived areas. There are successful interventions across the United Kingdom for young children based on toothbrushing with fluoride toothpaste. However, evidence is lacking for oral health improvement progra…

OBJECTIVES: Virtual colonoscopy is less invasive than conventional colonoscopy and does not require a conscious sedation. BACKGROUND: Virtual colonoscopy using the abdominal spiral computed tomography scanning allows a total colonic evaluation with minimal invasiveness. METHODS: We studied 48 patients with a virtual…

BACKGROUND: Biological data have traditionally been stored and made publicly available through a variety of on-line databases, whereas biological knowledge has traditionally been found in the printed literature. With journals now on-line and providing an increasing amount of open access content, often free of copyright…

Accurate organ segmentation is essential for clinical tasks such as radiotherapy planning and disease monitoring. Recent foundation models like MedSAM achieve strong results using point or bounding‑box prompts but still require manual interaction. We propose DescriptorMedSAM, a lightweight extension of MedSAM th…

The most common among dementias is Alzheimer's disease (AD). At the beginning it is controllable by medications but, as the disease advances, the patient needs a 24-hour care and very often one family member has to devote him/herself to the permanent care of the ill. AD dictates both patient's and family member's lives…

BACKGROUND: The purpose of the study was to evaluate the utility of fine needle aspiration--FNA and cytologic analysis of impalpable complicated breast cysts. MATERIAL AND METHODS: We rewieved the imaging findings, aspiration, cytology and biopsy results and followup imaging findings of 246 complicated cysts in 166 wo…

Sequence specific cleavage of RNA can be achieved by hammerhead ribozymes as well as DNAzymes. They comprise a catalytic core sequence flanked by regions that form double strands with complementary RNA. While different types of ribozymes have been discovered in natural organisms, DNAzymes derive from in vitro selection…

As opposed to malignant secondary tumors, metastases of the colorectal carcinoma are benign tumors of the liver that are quite rare in the Czech Republic. From the 55 patients operated on since 2000 at our department for benign liver tumors, the most frequent are haemangiomas, focal nodular hyperplasia (FNH) and hepato…

Individual processive molecular motors, of which conventional kinesin is the most studied quantitatively, move along polar molecular tracks and, by exerting a force F = (F(x),F(y),F(z)) on a tether, drag cellular cargoes, in vivo, or spherical beads, in vitro, taking up to hundreds of nanometre-scale steps. From observ…
