ANATOMICAL AND BIOMECHANICAL ROLE OF STATIC STABILIZERS OF THE ACROMIOCLAVICULAR JOINT.

Objective: The aim: To determine the anatomical and biomechanical significance of the static stabilizers of the acromioclavicular joint by conducting numerical modeling using the finite element method and experimental investigation.

Patients And Methods: Materials and methods: To ensure the study, modeling of the deformation processes of the clavicle and scapula systems with various combinations of ligament damage was conducted. The COMPAS-3D software package was used to build the simulation model, which allowed obtaining models that are closest to reality.

Protonated Organic Diamines as Templates for Layered and Microporous Structures: Synthesis, Crystal Chemistry, and Structural Trends among the Compounds Formed in Aqueous Systems Transition Metal Halide or Nitrate-Diamine-Selenious Acid.

Systematic studies of crystalline compounds formed in aqueous systems containing aliphatic diamines, divalent transition metal halides, and selenious acid resulted in the discovery of a large family of new complex species corresponding to several new structure types. With ethylenediamine (en), layered (enH)[(HSeO)] compounds are the most commonly formed species which constitute a significant contribution to the family of layered hydrogen selenites containing neutral [(HSeO)] ( = Mg, Mn, Co, Ni, Cu, Zn, Cd) 2 building blocks. In contrast to some previous suggestions, piperazine (pip), as well as its homologue N-methylpiperazine, mostly give rise to quite different, sometimes more complex, structures of varied dimensionality while the (pipH)[(HSeO)] compounds are formed only with = Cu and Cd.

BIOMECHANICAL STUDY OF MINIMALLY INVASIVE TECHNIQUES IN SURGICAL TREATMENT OF THE TIBIA PROXIMAL EPIMETAPHYSIS FRACTURES.

Objective: The aim: Improving efficiency of the tibia proximal epimetaphysis fractures treatment by introducing minimally invasive techniques using the up-to-date metallic constructions.

Patients And Methods: Materials and methods: The study is based on the results of examination and treatment of 119 patients, using arthroscopic technique. The results were evaluated regarding the P.

Proteogenomic insights suggest druggable pathways in endometrial carcinoma.

We characterized a prospective endometrial carcinoma (EC) cohort containing 138 tumors and 20 enriched normal tissues using 10 different omics platforms. Targeted quantitation of two peptides can predict antigen processing and presentation machinery activity, and may inform patient selection for immunotherapy. Association analysis between MYC activity and metformin treatment in both patients and cell lines suggests a potential role for metformin treatment in non-diabetic patients with elevated MYC activity.

MAGNETIC RESONANCE IMAGING DETERMINATION OF STRUCTURAL DISORDERS OF ARTICULAR CARTILAGE: MODERN DIAGNOSTIC TECHNOLOGIES AND RESEARCH PROSPECTS.

Objective: The aim: Tо present enhanced (with the contrast) and non-enhanced MRI techniques, provide an update on the physical principles of the main and latest techniques, and describe the advantages and disadvantages of each technique. The information obtained can provide an opportunity to diagnose changes at the structural level of the articular cartilage, thereby improving the early diagnosis of OA and optimizing the tactics of further treatment of patients.

Patients And Methods: Materials and methods: We retrospectively reviewed publications published in the PubMed and Embase databases up to February 2023 using the following terms: "MRI cartilage", "MRI osteochondral lesion", "T2 mapping cartilage", "dGEMRIC", "DWI cartilage", "DTI cartilage", "sodium MRI cartilage", "gagCEST", "T1rho cartilage".
