PURPOSE: To report the findings in three cases in which the average foveal thickness was increased after a thin epiretinal membrane (ERM) was removed by vitrectomy with internal limiting membrane (ILM) peeling. METHODS: The foveal contour was normal preoperatively in all eyes. All cases underwent successful phacovitrectomy with ILM peeling for a thin ERM. The optical coherence tomography (OCT) images were examined before and after the surgery. The changes in the average foveal (1 mm) thickness and the foveal areas within 500 μm from the foveal center were measured...

In this study, novel human-derived epithelial-like cells (hEPLCs) lines were established from periodontal ligament (PDL) tissues, which were composed of a variety of cell types and exhibited complex cellular activities. To elucidate the putative features distinguishing these from epithelial rest of Malassez (ERM), we characterized hEPLCs based on cell lineage markers and tight junction protein expression. The aim of this study was, therefore, to establish and characterize hEPLCs lines from PDL tissues. The hEPLCs were isolated from PDL of third molar teeth...

Falls are the cause for more than half of the injury-related hospitalizations among older people. Accurate assessment of individuals' fall risk could enable targeted interventions to reduce the risk. This paper presents a novel method for using wearable accelerometers to detect early signs of deficits in balance from gait. Gait acceleration data were analyzed from 35 healthy female participants (73.86±5.40 years). The data were collected with waist-mounted accelerometer and the participants performed three supervised balance tests: Berg Balance Scale (BBS), Timed-Up-and-Go (TUG) and 4m walk...

BACKGROUND: In 2010, the 10-valent pneumococcal conjugate vaccine (PCV10) was introduced free of charge in Brazil as part of the public immunization program. Here we investigated the carriage prevalence, colonization risk factors, capsular types, and antimicrobial resistance among pneumococcal isolates obtained from children in Brazil four years after routine PCV10 use. METHODS: Between September and December 2014, we conducted a cross-sectional study among children<6years old who attended one public and two private clinics in Niterói, RJ, Brazil to evaluate pneumococcal nasopharyngeal carriage...

PURPOSE: The vitreous cortex, epiretinal membrane (ERM), and inner limiting membrane (ILM) are transparent tissues and are thus difficult to visualize. Staining these structures can increase the efficiency of a nontraumatic removal. METHODS: The surgeon performs a partial core vitrectomy and induces a posterior vitreous detachment. The vital dye is then injected into the retrohyaloid space in balanced salt solution (BSS). The dyes used are TWIN (Alchimia srl, Padova, Italy), MembraneBlue-Dual (DORC International, Zuidland, the Netherlands), and Doubledyne (Alfa Intes, Casoria, Italy)...

Technical advancements have substantially extended the indications for surgery in diabetic retinopathy (DR) during the last 40 years, from the traditional indications including non-clearing vitreous hemorrhage, traction retinal detachment (RD), and traction-rhegmatogenous RD, to epiretinal membrane (ERM), vitreomacular traction, diffuse macular edema, neovascular glaucoma, and anterior hyaloid fibrovascular proliferation. The goals of vitreoretinal surgery in DR are multiple: clearing media opacities, release of traction (anteroposterior and/or tangential), segmentation and/or removal of traction bands, peeling of ERMs, hemostasis, laser photocoagulation, and tamponade of retinal breaks with gas or silicone oil...

Costello syndrome (CS) patients suffer from a very high 10% incidence of embryonal rhabdomyosarcoma (ERMS). As tools to discover targeted therapeutic leads, we used a CS patient-derived ERMS cell line (CS242 ERMS) harboring a homozygous p.G12A mutation in HRAS, and a control cell line derived from the same patient comprising non-malignant CS242 fibroblasts with a heterozygous p.G12A HRAS mutation. A library of 2,000 compounds with known pharmacological activities was screened for their effect on CS242 ERMS cell viability...

OBJECTIVE: Despite the promising results related to intuitive eating, few studies have attempted to explain the processes encouraging this adaptive eating behaviour. The focus of the present study was on exploring mechanisms of change in intuitive eating and weight in acceptance and commitment therapy (ACT) interventions. Mediation provides important information regarding the treatment processes and theoretical models related to specific treatment approaches. The study investigates whether psychological flexibility, mindfulness skills and sense of coherence mediated the interventions' effect on intuitive eating and weight...

Campylobacter spp., especially Campylobacter jejuni and C. coli, are leading bacterial foodborne pathogens worldwide. In the United States, an estimated 0.8 million cases of campylobacteriosis occur annually, mostly involving C. jejuni. Campylobacteriosis is generally self-limiting but in severe cases treatment with antibiotics may be mandated. Increasing incidence of fluoroquinolone resistance in Campylobacter has rendered macrolides like erythromycin and azithromycin the drugs of choice for human campylobacteriosis...

It was reported that stimulation of TAS2R38 by a bitter substance, phenylthiocarbamide (PTC), increased P-gp mRNA level and transport activity via release of the gastrointestinal hormone cholecystokinin-8 (CCK-8) at 9 hours. Therefore, we hypothesized that CCK-8 and PTC might also regulate P-gp activity more rapidly via a different mechanism. As a result, we found that the pretreatment of Caco-2 cells with 10 mM PTC significantly decreased the intracellular accumulation of P-gp substrate Rho123 compared with the control after 90 min incubation...

The European reference method (ERM) recognises the fraudulent addition of bovine (B) milk in water buffalo (WB) milk/dairy products based on concomitant isoelectric focusing (IEF) detection of B γ2- and γ3-CN fragments after corresponding plasminolysis. We here used proteomics to characterise false positive results occurring in the ERM as being due to WB β-CN(f100-209), which is also formed after plasminolysis of genuine WB milk/dairy products and comigrates in IEF with B γ2-CN. These ERM limitations were overcome by a dedicated proteomic procedure based on loading of B/WB milk/cheese CN extracts on a hydroxyapatite column, in situ trypsinolysis and elution of B β-CN(f1-25)4P and WB β-CN(f1-28)4P proteotypic peptides...

BACKGROUND: To evaluate macular changes in fellow eyes of patients diagnosed with lamellar macular hole (LMH) using spectral-domain optical coherence tomography (SD-OCT) and blue fundus autofluorescence (B-FAF). METHODS: Fellow eyes of patients diagnosed with a LMH were retrospectively evaluated on OCT. Best-corrected visual acuity (BCVA) and central foveal thickness (CFT) were recorded. Corresponding B-FAF images, vitreo-macular relations, and type of epiretinal membranes (ERMs) were also examined...

Influenza virus NS2 is well known for its role in viral ribonucleoprotein nuclear export; however, its function has not been fully understood. A recent study showed that NS2 might interact with HIST1H1C (H1C, H1.2). Histones have been found to affect influenza virus replication, such as the H2A, H2B, H3, and H4, but H1 has not been detected. Here, we found that H1C interacts with NS2 via its C-terminal in the nucleus and that H1C affects influenza virus replication. The H1N1 influenza virus replicates better in H1C knockout A549 cells compared to wild-type A549 cells, primarily because of the regulation of H1C on interferon-β (IFN-β)...

Ezrin/radixin/moesin (ERM) proteins function as general cross-linkers between plasma membrane proteins and the actin cytoskeleton and are involved in the functional expression of membrane proteins on the cell surface. They also integrate Rho guanosine 5'-triphosphatase (GTPase) signaling to regulate cytoskeletal organization by sequestering Rho-related proteins. They act as protein kinase A (PKA)-anchoring proteins and sequester PKA close to its target proteins for their effective phosphorylation and functional regulation...

Rhabdomyosarcoma (RMS), which represents the most frequent soft tissue sarcoma in pediatric populations, is classified into two major subtypes: embryonal RMS (ERMS) and alveolar RMS (ARMS). ARMS subtype, which shows greater aggressiveness and proneness to metastasis with respect to ERMS, are characterized, in about 75% of cases, by specific chromosomal translocations that involve PAX and FOXO1 genes. Many findings have demonstrated that PAX/FOXO1-positive ARMS have a worse prognosis than PAX/FOXO1-negative ones and that distinct molecular features characterize RMS with different gene fusion statuses...

γ2 adaptin is homologous to γ1, but is only expressed in vertebrates while γ1 is found in all eukaryotes. We know little about γ2 functions and their relation to γ1. γ1 is an adaptin of the heterotetrameric AP-1 complexes, which sort proteins in and do form clathrin-coated transport vesicles and they also regulate maturation of early endosomes. γ1 knockout mice develop only to blastocysts and thus γ2 does not compensate γ1-deficiency in development. γ2 has not been classified as a clathrin-coated vesicle adaptor protein in proteome analyses and functions for monomeric γ2 in endosomal protein sorting have been proposed, but adaptin interaction studies suggested formation of heterotetrameric AP-1/γ2 complexes...

The nascent peptide exit tunnel has recently been identified as a functional region of ribosomes contributing to translation regulation and co-translational protein folding. Inducible expression of the erm resistance genes depends on ribosome stalling at specific codons of an upstream open reading frame in the presence of an exit tunnel-bound macrolide antibiotic. The molecular basis for this translation arrest is still not fully understood. Here, we used a nucleotide analog interference approach to unravel important functional groups on 23S rRNA residues in the ribosomal exit tunnel for ribosome stalling on the ErmC leader peptide...

Amylin is an important gut-brain axis hormone. Since amylin and amyloid-β peptide (Aβ) share similar β sheet secondary structure despite not having the same primary sequences, we hypothesized that the accumulation of Aβ in the brains of subjects with Alzheimer's disease (AD) might compete with amylin for binding to the amylin receptor (AmR). If true, adding exogenous amylin type peptides would compete with Aβ and reduce the AD pathological cascade, improving cognition. Here we report that a 10-week course of peripheral treatment with human amylin significantly reduced multiple different markers associated with AD pathology, including reducing levels of phospho-tau, insoluble tau, two inflammatory markers (Iba1 and CD68), as well as cerebral Aβ...
