There is currently a widespread societal expectation for businesses to respect and support human rights. The apparent simplicity of this expectation contrasts sharply against the difficulty of specifying with precision the boundaries of corporate social responsibilities (CSR). This Article argues that the basis of these difficulties is the uncertainty regarding the responsibility of a business for

Objective. To determine in a cross sectional study the concentrations of stromelysin, tissue inhibitor of metalloproteinases (TIMP), and proteoglycan fragments in knee synovial fluid (SF) at different times after injury to cruciate ligament or meniscus. Methods. Joint fluid samples were obtained from patients with knee injury diagnosed by arthroscopy. Concentrations of stromelysin-1 and TIMP-1 wer

Various markers of the metabolism of articular cartilage have been identified in synovial fluid, blood, and urine of patients with osteoarthritis (OA). The joint fluid level of a cartilage-derived molecule, or its fragment, can be used as a marker of the synthesis or catabolism of that molecule in the articular surfaces within that joint. In blood and urine, on the other hand, the level of a marke

Osteoarthritis of the knee is not a well defined illness, but is a result of different causes that may lead to joint failure due to chondral damage, synovial inflammation, subchondral bone formation, and the formation of osteophytes along the joint lines. The pathogenesis is unclear. We still lack treatment to cure the early prosess of chondral degeneration. The treatment of choice in early and mo

Flexor tendon segments were incubated in a diffusion chamber in the subcutis of rabbits. Tendons incubated up to 6 weeks in the diffusion chamber showed proliferating and migrating cells from the epitenon cell layer as well as viable endotenon cells. Explants frozen in liquid nitrogen prior to incubation showed no signs of extrinsic cell contamination and remained non-viable indicating that no cel

High tibial osteotomy was performed for medial gonarthrosis in 28 patients. Preoperatively, and at 3, 12, and 24 months after surgery, clinical and radiographic examinations were made, and joint-fluid samples were aspirated. Arthroscopy was performed preoperatively and at 24 months. Immunoassay of proteoglycan epitope in joint fluid showed an increase in concentration at all times as compared with

Objective. To determine the proteolytic fragmentation patterns and N-terminal sequence of aggrecan fragments in human synovial fluid from patients with inflammatory arthritides, joint injury, or osteoarthritis (OA). Methods. Knee synovial fluid was obtained from patients with joint injury, OA, acute pyrophosphate arthritis (pseudogout), reactive arthritis, psoriatic arthritis, or juvenile rheumato

Tendon healing and integration of tendon grafts may be site or donor specific. To determine if differences exist in sensitivity to growth factors that have the potential to influence tendon repair, we compared the effect of recombinant human insulin-like growth factor-1 on various types of tendon segments. The dose response effects on proteoglycan, collagen, noncollagen protein, and DNA synthesis

The Knee injury and Osteoarthritis Outcome Score (KOOS) is a self-administered instrument measuring outcome after knee injury at impairment, disability, and handicap level in five subscales. Reliability, validity, and responsiveness of a Swedish version was assessed in 142 patients who underwent arthroscopy because of injury to the menisci, anterior cruciate ligament, or cartilage of the knee. The

Corporate Social Responsibility (CSR) has been customarily seen as an inherently voluntary corporate endeavour that inhabits the area stretching ‘beyond compliance’ with law. However a growing number of writers and practitioners deem this understanding of CSR inaccurate and unproductive. In this article CSR as ‘beyond compliance’ is questioned from logical, descriptive and normative points of view

Objective. To study the long-term outcome of surgical removal of a meniscus in the knee with regard to radiographic signs of osteoarthritis (OA). Methods. Of the 123 patients who underwent an open meniscectomy due to an isolated meniscus tear in 1973 at Lund University Hospital, 107 were followed up 21 years later by clinical examination and by review of knee radiographs obtained with weight beari

Osteoarthritis is a heterogeneous and multifactorial disease with many pathogenic mechanisms implicated in its development and progression. Although osteoarthritis is a manifestation of certain metabolic, mechanical or inflammatory events, several distinct forms of osteoarthritis are inherited as dominantly acquired Mendelian traits. Gathering evidence is showing that inheritance and possible muta

We have grown GaAsP nanowires with high optical and structural quality by Aerotaxy, a new continuous gas phase mass production process to grow III-V semiconductor based nanowires. By varying the PH3/AsH3 ratio and growth temperature, size selected GaAs1-xPx nanowires (80 nm diameter) with pure zinc-blende structure and with direct band gap energies ranging from 1.42 to 1.90 eV (at 300 K), (i.e., 0

Long-term oxygen therapy (LTOT) ≥ 15 h/day improves survival in hypoxemic chronic obstructive pulmonary disease (COPD). LTOT 24 h/day is often recommended but may pose an unnecessary burden with no clear survival benefit compared with LTOT 15 h/day. The aim was to test the hypothesis that LTOT 24 h/day decreases all-cause, respiratory, and cardiovascular mortality compared to LTOT 15 h/day in hypo

The rapidly growing interest in photocatalytic systems for direct solar fuel production such as hydrogen generation from water splitting is grounded in the unique opportunity to achieve charge separation in molecular systems provided by electron transfer processes. In general, both photoinduced and catalytic processes involve complicated dynamics that depend on both structural and electronic effec
