Background Sports-related head trauma is common but still there no established laboratory test used in the diagnostics of minimal or mild traumatic brain injuries. Further effects recurrent on injury markers are unknown. The purpose this study was to investigate relationship between Olympic (amateur) boxing and cerebrospinal fluid (CSF) biomarkers. Methods designed as a prospective cohort study. Thirty boxers with minimum 45 bouts 25 non-boxing matched controls were included CSF samples...

In Brief Study Design. Descriptive experimental study in 4 different mammals. Objective. To investigate cell proliferation/regeneration and localize stem cells/progenitor cells within the intervertebral disc (IVD). Summary of Background Data. Disc degeneration (DD) is believed to play a major role patients with chronic lumbar pain. Lately, biologic treatment options for DD have gained increasing interest. Normal regeneration processes IVD previously been sparsely described therefore it great...

Today, the tool that is most commonly used to evaluate osteogenic differentiation of bone marrow stromal cells (BMSCs) in vitro demonstration expression multiple relevant markers, such as ALP, RUNX2 and OCN. However, yet, there no single surface marker or panel markers which clearly defines human BMSCs (hBMSCs) differentiating towards lineage. The aim this study was therefore examine issue. Stable isotope labeling by amino acids cell culture (SILAC)-based quantitative proteomics utilized...

There is a high prevalence of blood product transfusions in orthopedic surgery. The reported red cell unselected patients undergoing hip or knee replacement varies between 21% and 70%. We determined current loss transfusion total arthroplasty when tranexamic acid was used as routine prophylaxis, further investigated potential predictors for excessive requirement. In total, 193 consecutive unilateral (n = 114) 79) were included prospective observational study. Estimated perioperative...

Classification of musculoskeletal pain based on underlying mechanisms (nociceptive, neuropathic, and nociplastic pain) is challenging. In the absence a gold standard, verification features that could aid in discrimination between these clinical practice research depends expert consensus. This Delphi consensus study aimed to: (1) identify assessment findings are unique to mechanism category or shared no more than 2 categories (2) develop ranked list candidate potentially discriminate...

Abstract Autologous nucleus pulposus is known to have injurious effects on spinal nerve roots when applied epidurally. Both inflammatory and immunological mechanisms been implicated in this regard. Various proinflammatory substances might be released or activated by affect the endoneural root vessels. The present study assessed pulposus‐induced early vascular reactions possibility of blocking these with intravenous, high‐dose, methylprednisolone pretreatment. In 25 pigs, S2 S3 were exposed....

Low back pain is common and degenerated discs (DDs) are believed to be a major cause. In non-degenerated intervertebral (IVDs) presence of stem/progenitor cells was recently reported in different mammals (rabbit, rat, pig). Understanding processes disc degeneration regenerative mechanisms within DDs important. The aim the study examine local human if these cell populations could respond paracrine stimulation vitro. Tissue biopsies from IVD region (L3-S1) were collected 15 patients, age 34-69...

Abstract Mesenchymal stem cells (MSCs) are a candidate for replacing chondrocytes in cell‐based repair of cartilage lesions. However, it has not been clarified if these can acquire the hyaline phenotype, and whether MSCs show same expression patterns critical control genes development. In order to study this, articular iliac crest derived were allowed differentiate pellet mass cultures. Gene markers helix‐loop‐helix (HLH) transcription factors, chondrogenic factors analyzed by real‐time PCR....
