Exposure to pesticides may increase the generation of reactive oxygen species (ROS), leading to oxidation of cell membrane lipids and proteins. Although fruit bats are potentially exposed to pesticides during their entire lifespan, the impacts of this exposure are still poorly investigated. We examined the effects of low, commercially recommended concentrations (0, 1.05 and 2.1 g/l) of an organochlorine insecticide endosulfan (EDS) formulation on oxidative responses in the liver and kidneys of Neotropical fruit bats (Artibeus lituratus), as well as possible liver morphological alterations following a 35-day oral exposure...

We combined the desirable properties of tungsten sulfide and reduced graphene oxide (rGO) and fabricated the hybrid materials through simultaneous electrochemical reduction and synthesis, as a versatile and environmentally benign alternative to conventional fabrication techniques. We synthesised a mixed WS2/WS3 film-like material (WS3-x) directly onto GO-modified glassy carbon electrodes via cyclic voltammetry (CV) and the resultant hybrid materials (WS3-x/rGO) were thoroughly characterised using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) as well as Raman spectroscopy...

Present study addresses potential of fungal strains, isolated from deteriorated mural paintings and surrounding air environment of the Church of the Holy Ascension in Veliki Krčimir (Serbia), to precipitate mycogenic minerals, when cultivated on agarized B4 medium. Utilizing culture-based isolation methods, 38 filamentous fungi were obtained in total, 23 from mural paintings and 15 from air, respectively, mainly ascomycetes, while Bjerkandera adusta and Thanatephorus cucumeris were only basidiomycetes. A total of 31 of 38 fungal isolates, more than 80%, were able to form minerals of different morphologies and variable size, determined via SEM-EDS and XRPD, to be either calcite or calcite and weddellite association...

We have previously identified a novel inhibitor of influenza virus in mouse saliva that halts the progression of susceptible viruses from the upper to the lower respiratory tract of mice in vivo and neutralizes viral infectivity in MDCK cells. Here, we investigated the viral target of the salivary inhibitor by using reverse genetics to create hybrid viruses with some surface proteins derived from an inhibitor-sensitive strain and others from an inhibitor-resistant strain. These viruses demonstrated that the origin of the viral neuraminidase (NA), but not the hemagglutinin or matrix proteins, was the determinant of susceptibility to the inhibitor...

Introduction Narcolepsy is an orphan neurological disease and presents with sleep- wake, motoric, neuropsychiatric and metabolic symptoms. Narcolepsy with cataplexy is most commonly caused by an immune-mediated process including genetic and environmental factors, resulting in the selective loss of hypocretin-producing neurons. Narcolepsy has a major impact on workableness and quality of life. Areas covered This review provides an overview of the temporal available treatment options for narcolepsy (type 1 and 2) in adults, including authorization status by regulatory agencies...

BACKGROUND: Dyspnea is a frequent complaint in emergency departments (ED). It has a significant amount of subjective and affective components, therefore the dyspnea scores, based on the patients' rating, can be ambiguous. Our purpose was to develop and validate a simple scoring system to evaluate the severity of dyspnea in emergency care, based on objectively measured parameters. METHODS: We performed a double center, prospective, observational study including 350 patients who were admitted in EDs with dyspnea...

A heterostructural LiNi0.35Mn1.65O4-δ-LiNi0.5Mn1.5O4 was achieved via constructing the concentration-gradient material with an average composition of LiNi0.4Mn1.6O4-δ. The as-obtained samples have been characterized by the cross sectional scanning electron microscopy (SEM) and energy dispersive x-ray spectrometry (EDS) that the core material LiNi0.35Mn1.65O4-δ is encapsulated completely by a concentration-gradient shell with the outmost layer of LiNi0.5Mn1.5O4. Demonstrated by high resolution transmission electron microscopy (HRTEM) and X-ray photoelectron spectroscopy (XPS) analysis with low-energy Ar neutral beam etching method, the structurally stable P4332 phase on the surface coordinates the high conductive Fd-3m phase in the bulk without any detectable interface...

The use of engineered silver nanoparticles (AgNP) is widespread, with expected release to the terrestrial environment through the application of biosolids onto agricultural lands. The toxicity of AgNP and AgNO3 (as ionic Ag(+) ) to plant (Elymus lanceolatus and Trifolium pratense) and soil invertebrate (Eisenia andrei and Folsomia candida) species was assessed using silver-amended biosolids applied to a natural sandy loam soil. Bioavailable Ag(+) in soil samples was estimated using an ion-exchange technique applied to KNO3 soil extracts while exposure to dispersible AgNP was verified by single particle-ICP-MS and TEM-EDS analysis...

BACKGROUND: Inhibitor development is a major complication of treatment with factor VIII concentrates in hemophilia. Findings from studies among severe hemophilia A patients suggest that intensive treatment episodes increase the risk to develop inhibitors. OBJECTIVES: We set out to assess whether intensive treatment is also associated with an increased risk of inhibitor development among nonsevere hemophilia A patients. PATIENTS/METHODS: We performed a nested case-control study...

We investigated the association between human polymorphonuclear leukocytes (PMNs) and non-opsonized Tannerella forsythia ATCC 43037 displaying a serum-resistant surface layer (S-layer). When PMNs were mixed with T. forsythia in suspension, the cells phagocytosed T. forsythia cells. Nitro blue tetrazolium (NBT) reduction, indicative of O2- production, was observed by light microscopy; cerium (Ce) perhydroxide deposition, indicative of H2 O2 production, was observed by electron microscopy. We examined the relationship between high-molecular-weight proteins of the S-layer and Ce reaction (for T...

Hypermobile Ehlers-Danlos syndrome (hEDS) is a common inherited connective tissue disorder characterized by joint hypermobility. The natural history of aortic root dilation (AoD), a potential complication of EDS, has not been well characterized in this population. We describe the natural history of aortic root size in a large cohort of patients with hEDS. A cohort of 325 patients with HEDS was identified at Cincinnati Children's Hospital Medical Center (CCHMC), including 163 patients from a previous study. Medical records were reviewed and each participant's height, weight, and aortic dimensions from up to four echocardiograms were documented...

Heterozygous mutations in the genes encoding the proα1(I) or proα2(I) chains of type I procollagen (COL1A1 and COL1A2, respectively) account for most cases of osteogenesis imperfecta (OI), a disorder characterized by reduced bone strength and increased fracture risk. COL1A1 mutations can also cause rare cases of Ehlers-Danlos syndrome (EDS), a disorder that primarily affects connective tissue and often includes reduced bone mass. Here we present a kindred of three young siblings ages 1-4 years old whose mother has a history of mild type I OI...

OBJECTIVE: Evidence indicates that males account for a significant minority of patients with eating disorders (EDs). However, prior research has been limited by inclusion of small and predominantly non-clinical samples of males. This study aimed to (1) provide male clinical norms for widely used ED measures (Eating Disorder Examination Questionnaire [EDE-Q] and Eating Disorder Inventory-3 [EDI-3]) and (2) examine sex differences in overall ED psychopathology. METHOD: Participants were 386 male and 1,487 female patients with an ED diagnosis aged 16 years and older who completed the EDE-Q and EDI-3 upon admission to a residential or partial hospital ED treatment program...
