Reevaluation of Phytase Action Mechanism in Animal Nutrition.

The release of phosphorus from phytates occurs via sequential cleavage of phosphate groups. It was believed that, regardless of the properties of phytases, the rate of phytate dephosphorylation is limited by the first cleavage of any phosphate group. The position of the first cleaved-off phosphate group depending on the specificity of phytase.

Effect of Mild Traumatic Brain Injury on Behavioral Reactions and Neocortical Morphology in Rats.

The original weight-drop model was employed to examine the effect of mild traumatic brain injury (TBI) on behavioral phenotype and neocortical morphology in rats. The neurological examination of rats with moderate TBI revealed the focal symptoms corresponding to pronounced neurological disorders, whereas in rats after mild TBI, there were only minor coordination disorders. On day 7 after injury, the rats with mild TBI demonstrated enhanced anxiety assessed by conditioned passive avoidance response.

Soluble forms of immune checkpoints in ovarian cancer.

The data of a complex immunoassay comparative study of the content of soluble forms of sPD-1, sPD-L1, sNKG2D, sNKG2DL1, sB7-H3 and sHLA-G in the blood plasma of 75 patients with epithelial ovarian cancer and 20 healthy donors of the control group are presented. The diagnostic significance of the studied proteins was determined. The study showed that the profile of soluble immunity checkpoints differs when malignant ovarian pathology occurs.

Morphological Characteristics of the Osteoplastic Potential of Synthetic CaSiO/HAp Powder Biocomposite.

The study describes the influence of synthetic CaSiO/HAp powder biocomposite on the process of regeneration in osseous tissue in the alveolar ridges in terms of the morphological characteristics of the osteoplastic potential. The authors investigated the osteoinduction and osteoconduction "in vivo" processes during bone tissue regeneration in the mandible defect area of an experimental animal (rabbit). The possibility of angiogenesis in the graft as an adaptation factor was studied in the process of bone tissue regeneration.

[Digital image in the practice of Cytology: a pilot study.].

Cytological study is a highly specialized type of laboratory analysis of the cellular composition of biological material and is to assess the morphological characteristics of cellular elements. The modern development of digital technologies is increasingly forming the interest of specialists to such a section as telepathology (digital pathology), which is a process of virtual microscopy with the transformation of classical cytological preparations into digital. Most morphologists currently use some forms of digital imaging, such as static images obtained by optical cameras mounted under a microscope.
