BACKGROUND: The development of platelet-rich fibrin (PRF) drastically simplified the preparation procedure of platelet-concentrated biomaterials, such as platelet-rich plasma (PRP), and facilitated their clinical application. PRF's clinical effectiveness has often been demonstrated in pre-clinical and clinical studies; however, it is still controversial whether growth factors are significantly concentrated in PRF preparations to facilitate wound healing and tissue regeneration. To address this matter, we performed a comparative study of growth factor contents in PRP and its derivatives, such as advanced PRF (A-PRF) and concentrated growth factors (CGF)...

INTRODUCTION: Eosinophilic esophagitis (EoE) is a chronic, immune/antigen-mediated disease characterized clinically by symptoms related to esophageal dysfunction and histologically by a marked eosinophilic infiltrate in the esophageal mucosa. What was once considered a rare disease has nowadays become one of the most frequent esophageal diseases in the Western countries, occupying a place just next to the gastroesophageal reflux disease. EoE etiology and pathogenesis remain largely unknown, although most studies consider that allergic and genetic factors play the most important role...

While novel picornaviruses are being discovered in rodents, their host range and pathogenicity are largely unknown. We identified two novel picornaviruses, rosavirus B from the street rat, Norway rat, and rosavirus C from five different wild rat species (chestnut spiny rat, greater bandicoot rat, Indochinese forest rat, roof rat and Coxing's white-bellied rat) in China. Analysis of 13 complete genome sequences showed that "Rosavirus B" and "Rosavirus C" represent two potentially novel picornavirus species infecting different rodents...

Paul Ehrlich's techniques, published between 1879 and 1880, for staining blood films using coal tar dyes, and his method of differential blood cell counting, ended years of speculation regarding the classification of white cells. Acidic and basic dyes had allowed him to recognize eosinophil and basophil granules, respectively, work that was a direct continuation of his discovery of the tissue mast cell described in his doctoral thesis. Ehrlich went on to develop neutral dyes that identified epsilon granules in neutrophils ("cells with polymorphous nuclei")...

Aim. Compare EoE-AP with EoE-D for clinical, endoscopy (EGD), histology and outcomes and also with FAP-N. Method. Symptoms, physical findings, EGD, histology, symptom scores, and treatments were recorded for the three groups. Cluster analysis was done. Results. Dysphagia and abdominal pain were different in numbers but not statistically significant between EoE-AP and EoE-D. EGD, linear furrows, white exudates were more in the EoE-D and both combined were significant (p < 0.05). EoE-D, peak and mean eosinophils (p  0...

A range of wound dressings currently available in the UK and elsewhere, each claiming to possess different performance characteristics, can make dressing selection difficult. This report concentrates on the superabsorbent polymer dressings (SAPs) - which are designed to absorb medium to high levels of exudate and to maintain an 'ideal moist wound healing environment'. What do these dressings achieve, what are they suitable/not suitable for, and are all super-absorbent dressings equal in terms of performance and quality? When assessing the key performance characteristics of absorbency, moisture vapour transmission rate (MVTR), strikethrough and structural integrity, results show that SAPs are not all the same-in fact each of them varies considerably and may lend themselves to different wound aetiologies and usage conditions...

PURPOSE: Tuberculous pleural effusion (TPE) and parapneumonic effusion (PPE) are usually distinguished by cellular predominance and pleural fluid adenosine deaminase (ADA) levels. However, both diseases may occasionally show similar neutrophilic predominance and high ADA levels. In such cases, the differential diagnosis between TPE and PPE is challenging and has been rarely investigated. METHODS: A retrospective study was conducted on TPE and PPE patients with neutrophilic exudate and pleural fluid ADA levels ≥40 U/L...

Age-related macular degeneration (AMD) causes a progressive loss of photoreceptors in the macula. It is the most common cause of legal blindness in the United States, and some form of AMD is thought to affect more than 9 million individuals. Risk factors include older age, smoking, dyslipidemia, obesity, white race, female sex, and a family history of AMD. There are two types of advanced AMD: nonexudative (dry or geographic atrophy) and exudative (wet or neovascular). Both cause progressive central vision loss with intact peripheral vision...

Effects of rhizosphere properties on the rhizosphere priming effect (RPE) are unknown. This study aimed to link species variation in RPE with plant traits and rhizosphere properties. Four C3 species (chickpea, Cicer arietinum; field pea, Pisum sativum; wheat, Triticum aestivum; and white lupin, Lupinus albus) differing in soil acidification and root exudation, were grown in a C4 soil. The CO2 released from soil was trapped using a newly developed NaOH-trapping system. White lupin and wheat showed greater positive RPEs, in contrast to the negative RPE produced by chickpea...

BACKGROUND AND AIMS: Phosphoenolpyruvate carboxylase (PEPC) is a tightly regulated enzyme that controls carbohydrate partitioning to organic acid anions (malate, citrate) excreted in copious amounts by cluster roots of inorganic phosphate (Pi)-deprived white lupin plants. Excreted malate and citrate solubilize otherwise inaccessible sources of mineralized soil Pi for plant uptake. The aim of this study was to test the hypotheses that (1) PEPC is post-translationally activated by reversible phosphorylation in cluster roots of illuminated white lupin plants, and (2) light-dependent phosphorylation of cluster root PEPC is associated with elevated intracellular levels of sucrose and its signalling metabolite, trehalose-6-phosphate...

PURPOSE: Choroidal metastasis from bladder cancer is very rare, with only a handful of cases cited previously in the literature. We present a case of a patient who presented with a serous retinal detachment and a known history of bladder cancer, which he believed was controlled. Based on the clinical evaluation, his history of bladder cancer, and a retinal consult, a workup was initiated and he was found to have choroidal metastasis from his cancer. CASE REPORT: A 77-year-old white man presented with a 1-week history of blurry vision in his left eye and left-sided frontal headaches...
