Diagnostic methods and written advice for acute otitis media in primary health care.

Background: Otomicroscopy and pneumatic methods are superior to otoscopy alone in diagnosing acute otitis media (AOM). There is a lack of knowledge regarding the use of different diagnostic methods for AOM in primary health care in Sweden and Norway.

Methods: This cross-sectional study included a questionnaire completed by general practitioners (GPs) and specialist trainees (STs/residents/registrars) working in primary care in Sweden and Norway.

In Tandem Control of La-Doping and CuO-Heterojunction on SrTiO Perovskite by Double-Nozzle Flame Spray Pyrolysis: Selective H vs. CH Photocatalytic Production from HO/CHOH.

ABO perovskites offer versatile photoactive nano-templates that can be optimized towards specific technologies, either by means of doping or via heterojunction engineering. SrTiO is a well-studied perovskite photocatalyst, with a highly reducing conduction-band edge. Herein we present a Double-Nozzle Flame Spray Pyrolysis (DN-FSP) technology for the synthesis of high crystallinity SrTiO nanoparticles with controlled La-doping in tandem with SrTiO/CuO-heterojunction formation.

New Apoptosis Inducers Containing Anti-inflammatory Drugs and Pnictogen Derivatives: A New Strategy in the Development of Mitochondrial Targeting Chemotherapeutics.

{[Ag(Mef)(μ--DMSO)(μ--DMSO)(-DMSO)]·2(HO)} (), [Ag(Mef)(tpP)] (), [Ag(Mef)(tpAs)] (), and {2 [Ag(Mef)(tpSb)] (DMSO)} () were obtained by the conjugation of mefenamic acid (MefH), a nonsteroidal anti-inflammatory drug (NSAID), with a mitochondriotropic derivative of pnictogen tpE (tp = triphenyl group; E = P, As, and Sb) through silver(I). Their hydrophilicity was adjusted by their dispersion into sodium lauryl sulfate (SLS), forming SLS@-. - and SLS@- were characterized by their spectral data and X-ray crystallography.

Conjugation of triphenylantimony(V) with carvacrol against human breast cancer cells.

The organoantimony derivative of formula trans-O,O-[PhSb(Carv)] (TPAC) (CarvH = carvacrol) is obtained by the oxidation of triphenylstibine (PhSb) with hydrogen peroxide in the presence of carvacrol (CarvH). Physical methods such as X-ray Fluorescence (XRF) spectroscopy, single crystal and powder X-ray diffraction analysis (XRD and PXRD), Attenuated Total Reflection Fourier Transform Infra-red (ATR-FTIR) spectroscopy, Thermogravimetric Differential Thermal Analysis (TG-DTA) and Differential Scanning Calorimetry (DTG/DSC), confirm the retention of the formula of TPAC throughout the sample mass in solid state, while UV-Vis spectroscopy in the solution. TPAC is the first example of carvacrol (the main ingredient of oregano) covalently bonded to any metal ion.

Hydrogels containing water soluble conjugates of silver(I) ions with amino acids, metabolites or natural products for non infectious contact lenses.

The poor handling and hygiene practices of contact lenses are the key reasons for their frequent contamination, and are responsible for developing ocular complications, such as microbial keratitis (MK). Thus there is a strong demand for the development of biomaterials of which contact lenses are made, combined with antimicrobial agents. For this purpose, the known water soluble silver(I) covalent polymers of glycine (GlyH), urea (U) and the salicylic acid (SalH) of formulae [Ag(Gly)NO] (AGGLY), [Ag(U)NO] (AGU), and dimeric [Ag(salH)] (AGSAL) were used.
