PURPOSE: To study the relationship between the size of primary full-thickness macular hole (MH) and the vitreomacular attachment status. DESIGN: Single-centre retrospective observational case series. METHODS: The records of 100 consecutive eyes operated for primary full-thickness MH were retrospectively reviewed. The vitreous status and MH diameter were assessed on the preoperative optical coherence tomography scans. MH were classified depending on the presence or absence of vitreomacular traction (VMT) and their size as small (<250 µm), medium (250-400 µm) and large (>400 µm), as suggested in the International VMT Study Group Classification...

The temporal and spatial properties of DNA replication in plants related to DNA damage and mutagenesis is poorly understood. Experiments were carried out to explore the relationships between DNA replication, chromatin structure and DNA damage in nuclei from barley root tips. We quantitavely analysed the topological organisation of replication foci using pulse EdU labelling during the S phase and its relationship with the DNA damage induced by mutagenic treatment with maleic hydrazide (MH), nitroso-N-methyl-urea (MNU) and gamma ray...

Over the past decades, electrospray ionization for mass spectrometry (ESI-MS) has become one of the most commonly employed techniques in analytical chemistry, mainly due to its broad applicability to polar and semipolar compounds and the superior selectivity which is achieved in combination with high resolution separation techniques. However, responsiveness of an analytical method also determines its suitability for the quantitation of chemical compounds; and in electrospray ionization for mass spectrometry, it can vary significantly among different analytes with identical solution concentrations...

BACKGROUND: Muscle mass maintenance is largely regulated by basal muscle protein synthesis rates and the ability to increase muscle protein synthesis after protein ingestion. To our knowledge, no previous studies have evaluated the impact of habituation to either low protein intake (LOW PRO) or high protein intake (HIGH PRO) on the postprandial muscle protein synthetic response. OBJECTIVE: We assessed the impact of LOW PRO compared with HIGH PRO on basal and postprandial muscle protein synthesis rates after the ingestion of 25 g whey protein...

α-Toxin, a pore-forming toxin secreted by most Staphylococcus aureus, plays critical role in the pathogenesis associated with various infectious diseases. The USA300 which is a major international epidemic methicilin-resisrant S. aureus has spread rapidly to multiple countries and become an emerging public health concern. In this study, the in vitro efficacy of Dracorhodin Perochlorate (DP) against USA300 virulence was evaluated. Using susceptibility testing, immunoblots, rabbit blood haemolytic assay and real-time RT-PCR, we observed that the α-toxin production was decreased when USA300 was co-cultured with different sub-inhibitory concentration of DP...

Next-generation sequencing (NGS) has reached the molecular diagnostic laboratories. Although the NGS technology aims to improve the effectiveness of therapies by selecting the most promising therapy, concerns are that NGS testing is expensive and that the 'benefits' are not yet in relation to these costs. In this study, we give an estimation of the costs and an institutional and national budget impact of various types of NGS tests in non-small-cell lung cancer (NSCLC) and melanoma patients within The Netherlands...

Bovine respiratory disease (BRD) is the most common and economically detrimental disease of beef cattle during the postweaning period, causing the majority of morbidity and mortality in feedlots. The pathogenesis of this disease often includes an initial viral infection, which can predispose cattle to a secondary bacterial infection. The objective of this experiment was to determine the effects of timing of an intratracheal (MH) challenge relative to 72 h of natural exposure to bovine viral diarrhea virus (BVDV) type 1b persistently infected (PI) calves on performance, serum antibody production, total and differential white blood cell (WBC) count, rectal temperature, clinical severity score (CS), and haptoglobin (Hp)...

H4 avian influenza virus is one of the most prevalent influenza virus subtypes in birds. The evolution and pathogenicity of H4 AIV in domestic birds of China remain largely unclear. In the present study, a total of eight H4 AIV strains isolated in duck farm and live poultry markets (LPM) were characterized. Phylogenetic analysis indicated that these strains are divided into two groups in the Eurasian lineage. Eight genes of MH-2/H4N6 isolated from a duck farm were closely related to three H4N6 viruses from LPM, suggesting a potential AIV link between farms and LPMs...

Purpose: Cytokines play an important role in cell signaling in inflammatory and repair processes, also within the posterior segment of the eye. These molecules are thus implicated in the pathophysiology of several vitreoretinal diseases. In the present study, we compared vitreal cytokine profiles in patients with idiopathic epiretinal membranes (ERMs) and idiopathic full-thickness macular holes (MHs) without epiretinal membranes. Methods: Native vitreal humor was collected during elective pars plana vitrectomy for the treatment of macular pathologies (group 1: ERM; group 2: MH) from patients without any other ocular or systemic disease...

INTRODUCTION: Numerous data sources suggest a decline in child sexual abuse (CSA) in the United States since the early 1990s. Some evidence also indicates that an earlier period of higher CSA incidence began following World War II. This study examines prevalence estimates of sexual abuse reported retrospectively as having occurred in childhood (ChSA) in two nationally representative surveys of the Canadian population. METHODS: Data are from 13 931 respondents aged 18 to 76 years from the 2004/2005 Canadian Gender, Alcohol, and Culture: An International Study (GENACIS), and from 22 169 household residents aged 18 years or older who participated in the 2012 Canadian Community Health Survey-Mental Health (CCHS-MH)...

: Early osteopathic theory and practice, and the work of the medical intuitive Edgar Cayce suggested that the abdominal areas of individuals with epilepsy would manifest "cold spots." The etiology for this phenomenon was thought to be abdominal adhesions caused by inflammation and viscero-somatic reflexes caused by adhesions or injury to visceral or musculoskeletal system structures. Indeed, until that advent of electroencephalography in the 1930s, medical practice regarding epilepsy focused on abdominal neural and visceral structures...

Despite the accumulated evidence showing the significant association between hypertension and obesity, it remains unclear how metabolic healthy status of obesity have an impact on the development of hypertension. Thus, this study was to investigate the risk of hypertension according to the metabolic healthy status stratified by the degree of obesity. A cohort of 25,442 Korean men without hypertension at baseline was followed-up from 2005 to 2010. They were divided into the following 6 phenotypes according to their baseline metabolic health and obesity status: metabolically healthy normal weight (MH-NW), metabolically healthy overweight (MH-OW), metabolically healthy obese (MHO), metabolically unhealthy normal weight (MU-NW), metabolically unhealthy overweight (MU-OW), and metabolically unhealthy obese (MUO)...

BACKGROUND: Risk factors for hemorrhage in patients with pelvic ring fracture have been widely reported. Because there are many risk factors, it is thought that prediction accuracy of hemorrhage in cases of pelvic ring fracture could be improved by using a scoring system. HYPOTHESIS: We investigated the risk factors for massive hemorrhage (MH) and created a novel predictive score of MH in pelvic ring fractures. MATERIAL AND METHODS: We retrospectively reviewed patients with pelvic ring fractures (Abbreviated Injury Score≥3 and age≥16 years) from January 2007 to June 2015...
