#1
Rugina Neuman, Marike Wabbijn, Samara Guillen, Adriaan Dees
We describe an unusual case of blue toe syndrome as the primary and solitary manifestation of systemic sclerosis. The possible cause was long-term occupational exposure in construction work. Blue toe syndrome is a small vessel disease, characterised by the sudden development of painful, blue discolouration in one or more toes. The most common aetiology is atheroembolic disease; however, it can also appear in several conditions ranging from hypercoagulability disorders to underlying systemic diseases such as vasculitis or autoimmune diseases...

Enamel opacity on anterior teeth can be prejudicial for the aesthetic appearance of affected patients. Patients with molar incisor hypomineralisation, for example, present opacities that can range from discrete white mottling to extensive yellow-brown discolourations. They can request a treatment to improve their aesthetic conditions. Many techniques have been considered to manage this condition. Wright developed a technique called etch-bleach-seal, which showed promising results for the management of anterior enamel opacities...

The genus Agaricus was recently rearranged to accommodate numerous tropical taxa. Accordingly, the genus was split into six subgenera and 22 sections of which 12 are included in A. subg. Pseudochitonia. Preliminary data indicated that three putative new species belong to this subgenus. Our objectives were to describe these species, to determine to which sections they belong, and to experience the interest of some traditional traits in this new context. We morphologically described Agaricus coniferarum from France and Portugal, Agaricus iranicus from Iran, and Agaricus lusitanicus from Portugal...

BACKGROUND: Indoor residual spraying of insecticide (IRS) is a key intervention for reducing the burden of malaria infection. Effectiveness and success of this strategy are to a considerable extent dependent on knowledge and practice of the target community regarding the IRS. Iran has entered the malaria elimination phase, and IRS has been considered as the main strategy for malaria vector control. Therefore, this study was conducted to determine the household knowledge and practices about malaria and IRS in Bashagard County, one of the malaria-endemic areas in the southeast of Iran...

We synthesised a new type of photochromic tungsten oxide nanoparticles, analysed their photocatalytic activity and carried out a thorough analysis of their effect on prokaryotic and eukaryotic organisms. Ultrasmall hydrated tungsten oxide nanoparticles were prepared by means of hydrothermal treatment of tungstic acid in the presence of polyvinylpyrrolidone as a template, stabiliser and growth regulator. Tungstic acid was synthesised through an ion-exchange method using sodium tungstate solution and a strongly acidic cation exchange resin...

Fusarium ananatum causes fruitlet core rot (FCR) in pineapple (Ananas comosus var. comosus) when the fruit reaches maturity. Hidden symptoms make it difficult to assess the disease, regardless of its stage, and basic questions concerning the involvement of the phenolic compounds in response to infection remain unknown. A direct inoculation method of F. ananatum in pineapple fruitlets was developed to monitor the growth of black spots and the changes in phenolic acids and ascorbic acid concentration under controlled conditions...

Subungual melanoma, an uncommon form of acral melanoma that arises within the nail matrix, accounts for 1%-3% of all cutaneous melanoma in Caucasians. As subungual melanoma presents in a more disguised manner than cutaneous lesions, increased vigilance is required. It most commonly presents as a discolouration of the nail, nail splitting or nail-bed bleeding. Black pigmentation of the adjacent nail fold, termed Hutchinson's sign, may be a diagnostic clue. Treatment of subungual melanoma remains surgical with wide local excision and amputation primary modalities...

Most vaccinations are performed by intramuscular injection with a needle and syringe. However, this method is not ideal due to limitations, such as the risk of needle-stick injury, the requirement for trained personnel to give injections and the need to reconstitute lyophilized vaccines. Therefore, we tested an alternative delivery technology that overcomes the problems with needle and syringe. The Nanopatch™ is an array of 10,000 silicon micro-projections per cm(2) that can be dry-coated with vaccine for skin delivery...

Mango is affected by different decline disorders causing significant losses to mango growers. In the United Arab Emirates (UAE), the pathogen was isolated from all tissues sampled from diseased trees affected by Lasiodiplodia theobromae. Symptoms at early stages of the disease included general wilting appearance of mango trees, and dieback of twigs. In advanced stages, the disease symptoms were also characterized by the curling and drying of leaves, leading to complete defoliation of the tree and discolouration of vascular regions of the stems and branches...

Pain is experienced by the vast majority of patients living with Parkinson's disease. It is most often of nociceptive origin, but may also be ascribed to neuropathic (radicular or central) or miscellaneous sources. The recently validated King's Parkinson's Disease Pain Scale is based on 7 domains including musculoskeletal pain, chronic body pain (central or visceral), fluctuation-related pain, nocturnal pain, oro-facial pain, pain with discolouration/oedema/swelling, and radicular pain. The basal ganglia integrate incoming nociceptive information and contribute to coordinated motor responses in pain avoidance and nocifensive behaviors...

Defects in the cilia gene RPGRIP1 cause Leber congenital amaurosis and cone-rod dystrophy in humans. A form of canine cone-rod dystrophy (cord1) was originally associated with a homozygous insertion in RPGRIP1 (RPGRIP1 (ins/ins)) as the primary disease locus while a homozygous deletion in MAP9 (MAP9 (del/del)) was later identified as a modifier associated with the early onset form. However, we find further variability in cone electroretinograms (ERGs) ranging from normal to absent in an extended RPGRIP1 (ins/ins) canine colony, irrespective of the MAP9 genotype...

5,8-Dihydroxy-[1,4]-naphthoquinone (DHNQ) is one of the key chromophores in cellulosic materials. Its almost ubiquitous presence in cellulosic materials makes it a target molecule of the pulp and paper industry's bleaching efforts. In the presented study, DHNQ was treated with hydrogen peroxide under alkaline conditions at pH 10, resembling the conditions of industrial hydrogen peroxide bleaching (P stage). The reaction mechanism, reaction intermediates, and final degradation products were analyzed by UV/vis, NMR, GC-MS, and EPR...

Turbidity associated with elevated suspended sediment concentrations can significantly reduce underwater light availability. Understanding the consequences for sensitive organisms such as corals and crustose coralline algae (CCA), requires an understanding of tolerance levels and the time course of effects. Adult colonies of Acropora millepora and Pocillopora acuta, juvenile P. acuta, and the CCA Porolithon onkodes were exposed to six light treatments of ~0, 0.02, 0.1, 0.4, 1.1 and 4.3 mol photons m(-2) d(-1), and their physiological responses were monitored over 30 d...

In this position paper, we review definitions related to this subject and the corresponding literature. Our recommendations include the following statements. Asymptomatic bacteriuria, asymptomatic leukocyturia, urine discolouration, odd smell or positive nitrite sediments are not an indication for antimicrobial treatment. Antimicrobial treatment of asymptomatic bacteriuria does not prevent periprosthetic joint infection, but is associated with adverse events, costs and antibiotic resistance development. Urine analyses or urine cultures in asymptomatic patients undergoing orthopaedic implants should be avoided...

BACKGROUND: Supra-nutritional vitamin E supplementation is a commonly used approach to delay lipid oxidation and colour deterioration in lamb and beef meat marketed under modified atmosphere packaging. However, these applications lack a precise calibration of dose for the desired effect and limited information is available regarding the use of natural vitamin E for this purpose. RESULTS: Three hundred and sixty Rasa Aragonesa lambs were fed diets supplemented with all-rac-α-tocopheryl acetate (250, 500, 1000 and 2000 mg kg(-1) compound feed), RRR-α-tocopheryl acetate (125, 250, 500 and 1000 mg kg(-1) compound feed) and a basal diet without vitamin E supplementation, for 14 days before slaughter at 25...
