Microbial quality of mechanically deboned beef (MDB), which was obtained by the discontinuous hydraulic horizontal separator, type Inject-Star (firm LASKA, Austria), was analyzed for the presence of indicatory microorganisms (coliforms and enterococci), pathogenic and conditionally pathogenic microorganisms. The basic microbial parameters have been determined separately for MDB of 1st, 2nd degrees as well as for average daily samples from one collecting vessel. Apart from it, also a raw material (beef from flesh bones intended for separation) and salt MDB after 24 hrs storing in chiller before working it into meat products were examined by the same way. From our results it follows that the number of all microorganisms observed in MDB of 1st degree was lower than that of 2nd degree. During the separation process the increase of microbial parameters compared with those in initial raw material occurred by 1-2 radices and following subsequent salting and storing in chiller there was a repeated decrease by 1 radix (with exception of the number of Staphylococci remaining unchanged). The change in the amount of microflora present was also influenced by season--in summer there was an increase by about 1 radix. From the view point of food hygiene the finding of salmonellas and the presence of large number of Staphylococci including Staphylococcus aureus on average 10(5).g-1 as well as the presence of wide extent of conditionally pathogenic microorganisms from the family of Enterobacteriaceae, especially from genera Proteus, Providencia, Morganella and Citrobacter are of great importance.

Neuropathic pain, a prevalent complication following spinal cord injury (SCI), severely impairs the life quality of patients. No ideal treatment exists due to incomplete knowledge on underlying neural processes. To explore the SCI-induced effect on nociceptive circuits, the protein expression of c-Fos was analyzed as an indicator of neuronal activation in a rat contusion model exhibiting below-level pain.

Purpose: Shear wave elastography (SWE) provides a means for adding information about the mechanical properties of tissues to a diagnostic ultrasound examination. It is important to understand the physics and methods by which the measurements are made to aid interpretation of the results as they relate to disease processes.
Methods: The components of how ultrasound is used to generate shear waves and make measurements of the induced motion are reviewed.

Introduction And Hypothesis: Stress urinary incontinence (SUI) is a highly prevalent condition in women. We hypothesized that the Tampsec™ vaginal tampon will be efficacious and well tolerated in its treatment.
Methods: This was a multicenter open-label parallel-group randomized control trial.

Introduction: Distal arterial occlusions can cause measurable changes in the flow wave profile in proximal segments of the feeding artery. Our objective was to study the diagnostic accuracy of point-of-care ultrasound (POCUS) of the common carotid arteries (CCA) for detection of anterior circulation large vessel occlusion (ac-LVO) in patients with suspected stroke.
Patients And Methods: We conducted a prospective, single-center, observational study of adult patients with suspected stroke admitted in the emergency department.

Since the 1950s, the woodcutting industry has relied heavily on tungsten carbide (WC) cutting tools to overcome the challenges posed by the complex structure of wood, including hard knots and abrasive elements such as sand and tannic acids. These demands require cutting tools with superior thermal conductivity and mechanical properties. However, the rising cost of WC materials has prompted the search for alternative solutions.
