Differences in cartilage biomarkers have been noted in patients with anterior cruciate ligament tears, but little is known about any similar relationship with shoulder instability. This study evaluated the relationship between serum cartilage biomarkers and shoulder instability. The authors present a prospective cohort study of young athletes followed from 2006 to 2010. A nested case-control analysis was conducted within this cohort to evaluate the association between preinjury collagen type II cleavage (a marker for type II collagen cleavage) and procollagen II carboxy propeptide (a marker of cartilage synthesis) and the subsequent likelihood of shoulder instability during the 4-year follow-up period...

Recent advances in the development of chlamydia vaccines, using live-attenuated or ultraviolet light-inactivated chlamydia, are paving the way for new possibilities to oppose the societal challenges posed by chlamydia-related diseases, such as blinding trachoma. An effective subunit vaccine would mitigate the risks associated with the use of a whole-cell vaccine. Our rationale for the design of an efficient subunit vaccine against Chlamydia trachomatis (Ct) is based on the membrane proteins involved in the initial Ct-host cell contact and on the route of immunization that mimics the natural infection process (i...

There is ongoing research with the goal of finding precise and sensitive biomarkers of multiple sclerosis (MS). Recently, researchers have paid particular attention to small, non-encoding, single stranded endogenous microRNA molecules (miR, miRNA). At first these molecules were thought to be found only within the cell. Today it is known, however, that they can also be found in the extracellular spaces (plasma, serum, saliva, urine, tears, sweat, milk, sperm and amniotic fluid, among others). It has been established that extracellular miRNA perform a wide spectrum of functions, such as transmitting signals between cells, modulating processes involved in angiogenesis, neurogenesis, proliferation or apoptosis...

The increasing understanding of immune mechanisms changed our perception of the ocular surface, which is now considered a compartment of the common mucosal immune system. It offered the possibility to alter the physiological immune response on the ocular surface and effectively combat inflammation, which impairs stability of the tear film and causes tear hyperosmolarity, causing symptoms of dry eye disease. The paper provides an overview of ocular surface anatomy and physiology, explains the underlying mechanisms of dry eye disease and discusses novel and promising treatment modalities, such as cyclosporine A, biological therapies using autologous serum and various growth factors as well as experimental treatment methods which are currently being investigated...

PURPOSE OF REVIEW: Conventional diagnostic tests in allergy are insufficient to clarify the cause of vernal conjunctivitis. Component-resolved diagnostic (CRD) by microarray allergen assay may be useful in detecting allergens that might be involved in the inflammatory process. RECENT FINDINGS: In a recent trial in patients suffered from eosinophilic esophagitis, after 2 years of the CRD-guided exclusion diet and specific immunotherapy, significant clinical improvement was observed, and 68% of patients were discharged (cure based on negative biopsy, no symptoms, and no medication intake)...

Chronic ocular surface diseases such as dry eye, blepharitis, and neurotrophic keratopathies represent a significant and a growing therapeutic challenge. The basis of this expanding prevalence is multifactorial and may due to issues such as an aging population, an increasing use of video display terminals, and increases in frequency of refractive surgeries. The growing incidence of diseases such as diabetes may also be a contributing factor. Current treatments for ocular surface disease include artificial tears, lubricants, tear duct plugs, steroids, antibiotics, cyclosporine, scleral lenses, and serum tears...

Kelp (Ascophyllum nodosum) is rich in iodine and often fed by organic dairy producers as a mineral supplement to support animal health. A commonly held belief is that kelp supplementation decreases susceptibility to infectious bovine keratoconjunctivitis due to increased iodine concentrations in tears. Whereas serum and milk iodine concentrations are positively correlated and modulated by oral iodine supplementation, nothing is known about the iodine concentration of tears. Therefore, the 3 objectives of this pilot study were to determine (1) the iodine content of tears, milk, and serum of cows after being fed kelp for 30d; (2) the trace mineral and thyroid status of cows before (d 0) and after being fed kelp for 30d; and (3) the in vitro growth rate of bacteria in tears (Moraxella bovis) or milk (Staphylococcus aureus, Escherichia coli, Streptococcus uberis) collected from cows fed no kelp (d 0) or kelp (d 30)...

INTRODUCTION: Vernal keratoconjunctivitis (VKC) is a bilateral multi-factorial disease. The pathogenesis of this disease is not obviously determined, but the role of various inflammatory cytokines has been specified. This study has provided a comparison between the level of interleukin-17 (IL17) in the serum and tears of case and control groups, and also the relationship between the level of this interleukin with severity of signs and symptoms of the disease. MATERIALS AND METHODS: This case-control study has been accomplished on 40 individuals (20 healthy people and 20 patients who suffer from VKC) in Al-Zahra Eye Center in 2014...
