Kenneth D Swanson, Bin Zheng
In this issue of Molecular Cell, Lin et al. (2018) report that chondroitin-4-sulfate, which is found in a common supplement meant to alleviate degenerative joint disorders, promotes the growth of BRAF V600E mutant melanoma. This study not only has implications for patient care but also sheds light on a novel mechanism for regulating phosphoinositide 3-kinase signaling.

An adrenal crisis (Addisonian crisis) is an acute life-threatening complication of adrenal insufficiency. It occurs when hydrocortisone demand is not met by supplementation in the context of an infection - often gastrointestinal, fever, trauma, acute psychological or physical stress. Symptoms of weakness, nausea, muscle/joint pain and drowsiness may develop out of robust health within few hours. If overlooked, treated too late, with insufficient dose or route of application, there exists a considerable risk of mortality...

N-3 polyunsaturated fatty acids (PUFA) have anti-inflammatory effects and were considered useful for the treatment of rheumatoid arthritis (RA). Recently, several studies suggested that n-3 PUFAs attenuated arthritis in animal model and human, however the mechanism is still unclear. Interleukin 17 (IL-17) is a pro-inflammatory cytokine mainly produced by T helper 17 (Th17) cells which cause tissue inflammation and bone erosion leading to joint destruction. In contrast, regulatory T (Treg) cells down-regulate various immune responses by suppression of naïve T cells...

INTRODUCTION: This study aims to compare the properties of currently available intra-articular hyaluronate (IA-HA) products widely available in the USA to those of healthy knee synovial fluid with respect to their bulk rheological properties. We hypothesize that products would have differing rheological properties, with some more closely resembling the properties and physiological aspects of healthy joint fluid HA. METHODS: We obtained reported HA product molecular weights, as well as measurements of the presence of cross-linking, zero shear rate viscosity, shear thinning ratio, and crossover frequency for the following IA-HA products available in the USA: Euflexxa® , Orthovisc® , Supartz® , Monovisc® , Synvisc® , Synvisc-One® , Gel-One® , and Hyalgan® ...

The striking predilection of temporomandibular disorders (TMD) in women, especially during gonad-intact puberty or reproductive years, indicates that oestrogen plays an important role in the progression of TMD, but the underlying mechanism remains unclear. In this study, unilateral anterior crossbite (UAC) was used to create temporomandibular joint osteoarthritis (TMJ OA) models in rats, while 17β-estradiol (E2 ) injections were applied to mimic patients with high-physiological levels of oestrogen. Micro-CT scanning, histological staining and real-time PCR assays were preformed to observe the degenerative changes in the mandibular condylar cartilage and subchondral bone...

The goal of this study was to evaluate the effectiveness of an oral joint supplement in working dogs with hip osteoarthritis compared with a positive control group (CG). Fifteen animals were divided in treatment group (TG, n = 10) and CG (n = 5). To TG a commercially available joint supplement, containing glucosamine HCl, chondroitin sulphate, and hyaluronic acid was given for 40 days and a 70-day course of a placebo, to be administered as if it was carprofen. The CG received carprofen for 70 days, and a placebo to be administered as the joint supplement...

BACKGROUND: Sarcopenic Obesity (SO) is characterized by low lean and high fat mass; i.e. from a functional aspect a disproportion between engine (muscle) and mass to be moved (fat). At present, most research focuses on the engine, but the close "cross talk" between age-associated adipose and skeletal muscle tissue inflammation calls for comprehensive interventions that affect both components alike. Protein and exercise are likely candidates, however with respect to the latter, the enthusiasm for intense and frequent exercise is rather low, especially in functionally limited older people...

People with hemophilia frequently suffer from arthropathy that leads to pain and functional impairment, ultimately resulting in reduced quality of life. The impact of pain and functional impairment on the lives of people with hemophilia was explored in the Pain, Functional Impairment, and Quality of Life (P-FiQ) study. Various patient-reported outcome (PRO) instruments were employed to assess the effect of pain and functional impairment on multiple aspects of health in people with hemophilia. The results presented in this supplement include detailed observations from PRO instruments regarding pain, functional impairment, anxiety, and depression, an analysis of the differences in health-related quality of life across subgroups of patients defined by demographic and treatment-related characteristics, and results of a modeling analysis to identify patient factors which influence perceptions of pain and functional impairment, independent of joint status...

BACKGROUND: United States (US) and coalition military medical units deployed to combat zones frequently encounter pediatric trauma patients. Pediatric patients may present unique challenges due to their anatomical and physiological characteristics and most military prehospital providers lack pediatric-specific training. A minimal amount of data exists to illuminate the prehospital care of pediatric patients in this environment. We describe the prehospital care of pediatric trauma patients in Iraq and Afghanistan...

Repair or regeneration of hyaline cartilage in knees, shoulders, intervertebral discs and other assorted joints is a major therapeutic target. To date, therapeutic strategies utilizing chondrocytes or mesenchymal stem cells are limited by expandability or the generation of mechanically inferior cartilage. Our objective is to generate robust cartilage-specific matrix from human mesenchymal stem cells suitable for further therapeutic development. Human mesenchymal stem cells, in an alginate 3D format, were supplied with individual sugars and chains which comprise the glycan component of proteoglycans in articular cartilage (galactose, hyaluronic acid, glucuronic acid and xylose) during chondrogenesis...

Unreasonably high irrigation levels and excessive nitrogen (N) supplementation are common occurrences in the North China Plain that affect winter wheat production. Therefore, a 6-yr-long stationary field experiment was conducted to investigate the effects of irrigation and N regimes on root development and their relationship with soil water and N use in different soil layers. Compared to the non-irrigated treatment (W0), a single irrigation at jointing (W1) significantly increased yield by 3.6-45.6%. With increases in water (W2, a second irrigation at flowering), grain yield was significantly improved by 14...
