This review summarises the present knowledge of diagnosing and treating hip joint pain. The results of joint preserving surgery are good in symptomatic patients with hip dysplasia, acetabular retroversion or impingement (cam or pincer) without signs of osteoarthritis. Confirmation of intraarticular pathology as the cause of symptoms is established clinically, and the pathology can in many cases be visualised by a standing, standardised radiograph of the pelvis, which is the basis for admission to the relevant orthopaedic department.

Biomedical scientists tend to focus on only a small fraction of the proteins encoded by the human genome despite overwhelming genetic evidence that many understudied proteins are important for human disease. One of the best ways to interrogate the function of a protein and to determine its relevance as a drug target is by using a pharmacological modulator, such as a chemical probe or an antibody. If these tools were available for most human proteins, it should be possible to translate the tremendous advances in genomics into a greater understanding of human health and disease, and catalyze the creation of innovative new medicines.

Femoroacetabular impingement syndrome (FAIS) is defined as a motion-related disorder of the hip joint, consisting of a triad of symptoms, clinical findings, and imaging findings. Hip morphology related to FAIS is developed during skeletal growth and seems to be related to sports participation. Treatment for FAIS may include physiotherapy and/or surgery, but recent evidence suggests, that surgery is more effective in improving symptoms.

Background: The Copenhagen Hip and Groin Outcome Score (HAGOS) was recently found valid, reliable, and responsive for patients undergoing hip arthroscopy. However, it is currently unknown to what degree patients undergoing hip arthroscopy improve and/or normalize their HAGOS result within the first year after surgery.

Purpose: First, to use HAGOS to evaluate clinical outcomes at 3, 6, and 12 months after hip arthroscopy for femoroacetabular impingement (FAI) and/or labral injury and compare the HAGOS results with the modified Harris Hip Score (mHHS).

Introduction: Hip arthroscopy has become a standard procedure in the treatment of hip joint pain not related to osteoarthritis or dysplasia in the young and active patient. There has been increasing focus on the contribution of the hip capsule to function and on stability following hip arthroscopy. It has been suggested that capsular closure after hip arthroscopy may prevent microinstability and macroinstability of the hip joint and reduce revision rate.

The Danish Hip Arthroscopy Registry (DHAR) was initiated in January 2012 as a web-based prospective registry. The purpose of this study was to evaluate and report the first registry based outcome data of a national population with radiological and clinical femoroacetabular impingement (FAI) undergoing hip arthroscopic treatment. Our primary hypothesis was that patients undergoing hip arthroscopy would improve significantly in pain, quality of life and sports related outcome measurements in Patient Related Outcome Measures (PROM).

Since hepatitis C virus (HCV) core protein is known to possess potential oncogenic activity, we explored whether oncolytic vesicular stomatitis virus (VSV) could efficiently induce cytolysis in hepatocellular carcinoma cells stably expressing HCV core protein (Hep3B-Core). We found that Hep3B-Core cells were more susceptible to VSV as compared to control (Hep3B-Vec) cells owing to core-mediated inactivation of STAT1 and STAT2 proteins. Core expression induced lower phosphorylation levels of type I IFN signaling proteins such as Tyk2 and Jak1, and a reduced response to exogenous IFN-α, which resulted in susceptibility to VSV.

Article Synopsis
  • Deregulation of the ErbB receptor network is linked to tumors in epithelial cancers, leading to the development of targeted therapies like afatinib, which irreversibly inhibits the ErbB receptor family to block cancer growth.
  • Afatinib binds covalently to various ErbB receptors, including EGFR and HER2, demonstrating strong inhibitory effects on cancer cell proliferation at low concentrations.
  • The unique acrylamide group in afatinib sets it apart from similar drugs, providing a mechanism for its potent and irreversible inhibition of ErbB kinases, which correlates with its observed clinical efficacy.

Within the last decades, the detailed knowledge on the impact of membrane bound drug efflux transporters of the ATP binding cassette (ABC) protein family on the pharmacological profile of drugs has enormously increased. Especially, ABCB1 (P-glycoprotein, P-gp, MDR1) has attracted particular interest in medicinal chemistry, since it determines the clinical efficacy, side effects and toxicity risks of drug candidates. Based on this, the development of in silico models that provide rapid and cost-effective screening tools for the classification of substrates and nonsubstrates of ABCB1 is an urgent need in contemporary ADMET profiling.
