PURPOSE: Chronic low back pain causes structural remodelling and inflammation in the multifidus muscle. Collagen expression is increased in the multifidus of humans with lumbar disc degeneration. However, the extent and mechanisms underlying the increased fibrotic activity in the multifidus are unknown. Physical activity reduces local inflammation that precedes multifidus fibrosis during intervertebral disc degeneration (IDD), but its effect on amelioration of fibrosis is unknown. This study aimed to assess the development of fibrosis and its underlying genetic network during IDD and the impact of physical activity...

The effect of omega-3 fatty acids on platelet aggregation and coagulation is highly unclear. Studies both support and refute the impacts of omega-3 fatty acids on prolonged bleeding time and platelet inhibition as well as its purported positive effects on cardiovascular disease. In a previous pilot study we suggested an inhibition of platelet aggregation measured with multiple electrode aggregometry. Following on that, the aim of the present study was to investigate the effects of supplementary high doses of omega-3 fatty acids on platelet aggregation and coagulation in a sample-size calculated number of healthy volunteers using Sonoclot, multiple electrode aggregometry, and flow-based Cellix instruments after 10 days of omega-3 fatty acid intake...

We used extensive data from a long-term study of great tits ( Parus major ) in the United Kingdom and Netherlands to better understand how genetic signatures of selection translate into variation in fitness and phenotypes. We found that genomic regions under differential selection contained candidate genes for bill morphology and used genetic architecture analyses to confirm that these genes, especially the collagen gene COL4A5 , explained variation in bill length. COL4A5 variation was associated with reproductive success, which, combined with spatiotemporal patterns of bill length, suggested ongoing selection for longer bills in the United Kingdom...

The general lack of well-preserved juvenile skeletal remains from Caribbean archaeological sites has, in the past, prevented evaluations of juvenile dietary changes. Canímar Abajo (Cuba), with a large number of well-preserved juvenile and adult skeletal remains, provided a unique opportunity to fully assess juvenile paleodiets from an ancient Caribbean population. Ages for the start and the end of weaning and possible food sources used for weaning were inferred by combining the results of two Bayesian probability models that help to reduce some of the uncertainties inherent to bone collagen isotope based paleodiet reconstructions...

1. Highly palatable and nutritious meat products can be produced through dietary interventions. Previous studies have shown that forage feeding has a significant impact on the growth performance and nutrition of cattle in various regions, but whether the same effects can be induced in geese remains unclear. 2. Three hundred and sixty Yangzhou goslings were divided according to body weight at 29 d old, assigned to one of 4 treatments and raised in separate pens. The treatments applied were (A) grazing, (B) grazing, grain supplemental diet (64 to 70 d), (C) grazing, grain supplemental diet and (D) confined...

OBJECTIVE: Fibromuscular dysplasia (FMD) is a non-atherosclerotic non-inflammatory arterial disease, which occurs mostly in middle-aged women and affects medium-sized arteries. We previously showed abnormalities within common carotid artery (CCA) wall, with the presence of triple signal (TS) at ultrasound suggesting the presence of supplementary layers. We aimed at coupling TS presence with microconstituents of the vessel wall, derived from fitting of the pressure-diameter curve. DESIGN AND METHOD: We included 50 non-smoking patients with multifocal FMD, 50 essential hypertensive (EH) patients and 50 healthy subjects (HS) matched for age, sex, ethnicity and BP (EH and FD)...

Meningeal Ewing Sarcoma (ES)/peripheral primitive neuroectodermal tumor (pPNET) is a rare diagnostically challenging small round cell tumor in the CNS. This study investigates the clinical pathological features of four cases of this tumor from archives of 6 years in our hospital. Patients were within the median age of 21.5 years and male to female ratio was 1:1. The tumors distributed at the supra-tentorial location, posterior fossa and lumbar vertebral canal, usually presenting as the dura-sited nodule or having close connection with the meninges within the cranium or vertebral canal...

Despite antibiotic treatment, up to 40% of patients have impaired fertility after epididymitis due to serovars of Escherichia coli, a frequent pathogen. The reasons for infertility are unclear, but it may result from epididymal duct obstruction. To determine whether E. coli infection of the epididymis causes obstruction due to fibrosis, and to identify the key mediators, tissues from patients with epididymitis were assessed. Additionally, epididymitis was induced with uropathogenic E. coli (UPEC) or commensal serovars in wild-type and MyD88(-/-) mice, which are relatively unresponsive to bacterial pathogens...
