We propose a model by which an increase in the genomic modification, 5-hydroxymethylcytosine (5hmC), contributes to B cell death within the chicken bursa of Fabricus (BF) infected with infectious bursal disease virus (IBDV). Our findings indicate that, following an IBDV infection, Rhode Island Red (RIR) chickens have fewer surviving B cells and higher levels of 5hmC in the BF than the more resistant 15l line of birds. Elevated genomic 5hmC levels within the RIR BF are associated with markers of immune responses: infiltrating T cells and increased expression of CD40L, FasL and iNOS...

Nasopharynx (NP) is anatomically difficult to explore adequately. The pharyngeal bursa (PB) is a recess lined with respiratory epithelium along the posterior wall of the nasopharynx between the longus capitis muscles. If the opening through which the bursa drains into the nasopharynx becomes obstructed, a Thornwaldt's cyst (TC) might develop. Small-sized cysts are mostly asymptomatic, whereas large-sized cysts may lead to various nasal and otologic symptoms depending on their localization. In this report, we present a 71-year-old case with a huge TC who presented to our clinic with the complaints of snoring, nasal obstruction, periodic halitosis, postnasal drip, headache, and hearing loss in the left ear and underwent total excision of the cyst through transnasal endoscopy...

Histone lysine acetylation is thought to play a role in regulating the balance between energy storage and energy expenditure. However, the epigenetic mechanisms by which food phytochemicals influence metabolic processes in the liver have not been thoroughly investigated. In this study, we investigated the effect of an ethanol extract of Capsella bursa-pastoris (ECB) on histone acetyltransferase (HAT) inhibition, and whether it could thereby attenuate lipid accumulation in vitro and in vivo. We observed that ECB inhibits HAT activity as assessed by colorimetric and autoradiography assay systems...

Superficial bursitis most often occurs in the olecranon and prepatellar bursae. Less common locations are the superficial infrapatellar and subcutaneous (superficial) calcaneal bursae. Chronic microtrauma (e.g., kneeling on the prepatellar bursa) is the most common cause of superficial bursitis. Other causes include acute trauma/hemorrhage, inflammatory disorders such as gout or rheumatoid arthritis, and infection (septic bursitis). Diagnosis is usually based on clinical presentation, with a particular focus on signs of septic bursitis...

INTRODUCTION: A popliteal cyst, also known as Baker cyst, is a benign fluctuant swelling of the gastrocnemius-semimembranosus bursa in the popliteal fossa at the back of the knee. The cyst is named after William Morrant Baker, who is considered to have first described this fluid collection with new sac formation outside of the knee-joint in 1877. We herein present a short description contained in the Galenic Corpus that appears to match to what we now call the Baker cyst. MATERIAL AND METHODS: Α thorough survey of Kühn's Galenic Corpus was performed...

BACKGROUND: The taxonomic status of the brown dog tick Rhipicephalus sanguineus (sensu stricto) is a subject of on-going debate; there is a consensus that populations of this tick species should be referred to as R. sanguineus (sensu lato) until its taxonomic status is resolved. Recent genetic studies revealed the existence of more than one lineage of R. sanguineus (s.l.) in temperate countries. In this study, we assessed the genetic identity of ticks collected from rural dogs living in several areas located in all major geographical regions of Portugal...

PURPOSE: There is no standard for measuring maximal diameter (Dmax) of abdominal aortic aneurysm (AAA) from computer tomography (CT) images although differences between Dmax evaluated from transversal (axialDmax) or orthogonal (orthoDmax) planes can be large especially for angulated AAAs. Therefore we investigated their correlations with alternative rupture risk indicators as peak wall stress (PWS) and peak wall rupture risk (PWRR) to decide which Dmax is more relevant in AAA rupture risk assessment...

BACKGROUND: Avian pathogenic E. coli (APEC) can lead to a loss in millions of dollars in poultry annually because of mortality and produce contamination. Studies have verified that many immune-related genes undergo changes in alternative splicing (AS), along with nonsense mediated decay (NMD), to regulate the immune system under different conditions. Therefore, the splicing profiles of primary lymphoid tissues with systemic APEC infection need to be comprehensively examined. RESULTS: Gene expression in RNAseq data were obtained for three different immune tissues (bone marrow, thymus, and bursa) from three phenotype birds (non-challenged, resistant, and susceptible birds) at two time points...

OBJECTIVE: The purpose of this study is to analyze MRI findings associated with posterior decentering of the humeral head on shoulder MR arthrogram. MATERIALS AND METHODS: A total of 255 MR arthrograms were obtained during a 10-month period. MR arthrograms in patients with posterior decentering of the humeral head (n = 33) were reviewed and compared with those of randomly selected control group without posterior decentering (n = 66). MR arthrograms were retrospectively evaluated by two observers for posterior factors (posterior synovial proliferation, posterior capsular thickening, and posterior labral abnormality), rotator cuff factors related to fatty degeneration, glenoid version, and anterior factors (subcoracoid bursa effusion and rotator interval tear)...

BACKGROUND: The role of (18)F-fluorodeoxyglucose positron emission computed tomography ((18)F-FDG PET/CT) is increasing in the diagnosis of polymyalgia rheumatica (PMR), one of the most common inflammatory rheumatic diseases. In addition to other locations, increased (18)F-FDG accumulation has been detected in the praepubic region in some patients. However, a deeper description and pathophysiological explanation of this increased praepubic accumulation has been lacking. The aim of the presented study is to confirm a decrease in praepubic (18)F-FDG accumulation in response to therapy and to describe potential correlations to other (18)F-FDG PET/CT scan characteristics during the course of disease...

Haglund's syndrome is impingement of the retrocalcaneal bursa and Achilles tendon caused by a prominence of the posterosuperior calcaneus. Radiographic measurements are not sensitive or specific for diagnosing Haglund's deformity. Localization of a bone deformity and tendinopathy in the same sagittal section of a magnetic resonance imaging scan can assist with the diagnosis in equivocal cases. The aim of the present cross-sectional study was to determine the prevalence of Haglund's syndrome in patients presenting with Achilles tendinopathy and note any associated findings to determine the criteria for a diagnosis of Haglund's syndrome...

Study Design Prospective, randomized, partially-blinded. Background Greater trochanteric pain syndrome (GTPS) is the current terminology for what was once called greater trochanteric or sub-gluteal bursitis. Cortisone (corticosteroid) injections into the lateral hip is a traditionally accepted treatment for this condition. However, the effectiveness of injecting the bursa with steroids is increasingly being questioned, and an equally effective treatment with fewer adverse side-effects would be beneficial. Objective To investigate whether administration of dry needling (DN) is non-inferior to cortisone injections in reducing lateral hip pain and improving function in patients with GTPS...

Cancer and tumors may evolve in response to life history trade-offs between growth and duration of development on one hand, and between growth and maintenance of immune function on the other. Here we tested whether (i) bird species with slow developmental rates for their body size experience low incidence of tumors because slow development allows for detection of rapid proliferation of cell lineages. We also test whether (ii) species with stronger immune response during development are more efficient at detecting tumor cells and hence suffer lower incidence of tumors...

Ambrosia pollen was first reported as an important allergen in North America at the end of the nineteenth century, and many European countries have recently reported its increasing significance for pollen allergy. The aims of this study were to determine whether the highly allergenic Ambrosia pollen recorded during the studied period could be the result of long-distance transport (LDT) and to identify the potential sources of Ambrosia pollen grains. The study investigates Ambrosia pollen episodes during the peak term of six yearly periods between 2010 and 2015 by examining source regions in Ambrosia pollen in Bursa, Turkey...

Os acromiale consist in a lack of fusion between the different ossification spots of the acromial side of scapula from the age of 23-25 years. A relation between os acromiale and some shoulder pathology like impingement syndrome, cuff tear and subacromial bursitis has been described. The etiology is not already known. The aim of this study was to evaluate the frequency of os acromiale in our population, the link between os acromiale and sex, side and shoulder pathology. 1042 shoulder MRI were evaluated to find out os acromiale and the linked cuff pathology...
