Conflicting results emerged from studies investigating cognitive performances in migraine patients. Based on clinical and neuroradiological aspects, the possible involvement of executive functions has been especially taken into consideration. The aim of this study was to evaluate, in a population of subjects affected by migraine without aura (MwoA), frontal lobe cognitive functions. We enrolled all the consecutive patients affected by MwoA referred to our headache centre for a first evaluation. Each patient underwent a neuropsychological evaluation including Raven coloured progressive matrices (CPM)...

To identify the house mice collected in Pokhara and Lumbini of Nepal at the subspecies level, morphological and molecular analyses were carried out. Morphologically, two populations collected in Pokhara and Lumbini were distinguished by fur colour, but there was no significant difference in external measurements (p > .05). The phylogenetic analysis results revealed that the haplotypes sequences of mitochondrial DNA (mtDNA) Cytochrome B (CytB) gene distinguished into two distinct clades on a phylogenetic tree representing two subspecies, Mus musculus bactrianus and M...

Herein we describe the synthesis and luminescence of nanosized (Lu1-y-xGdx)2O2S:Tby and (Lu1-y-xGdx)2O3:Tby phosphors with y = 0.1 mol% Tb(3+) and y = 2 mol% Tb(3+) and x ranging between 0 and 1. The concentration of Gd(3+) (x) was varied in steps of 0.1 (molar ratio Gd(3+)). The samples at 0.1 < x < 0.7 contained a mixture of (Lu1-xGdx)2O3:Tb(3+) and (Lu1-xGdx)2O2S:Tb(3+), while the samples at x = 0 contained only Lu2O3:Tb(3+). At 0.1 < x < 0.7 Lu2O2S:Tb(3+) and Gd2O2S:Tb(3+) did not form a solid solution, but rather crystallised into two slightly different hexagonal structures...

We report a simple colorimetric (naked-eye) and electrochemical method for the rapid, sensitive and specific quantification of global methylation levels using only 25 ng of input DNA. Our approach utilises a three-step strategy; (i) initial adsorption of the extracted, purified and denatured bisulfite-treated DNA on a screen-printed gold electrode (SPE-Au), (ii) immuno-recognition of methylated DNA using a horseradish peroxidase (HRP)-conjugated methylcytosine (HRP-5mC) antibody and (iii) subsequent colorimetric detection by the enzymatic oxidation of 3,3',5,5'-tetramethylbenzidin (TMB)/H2O2 which generated a blue-coloured product in the presence of methylated DNA and HRP-5mC immunocomplex...

Recent technological improvements in head and neck field have changed diagnostic and therapeutic strategies for salivary disorders. Diagnosis is now based on colour Doppler ultrasonography (US), magnetic resonance (MR) sialography and cone beam 3D computed tomography (CT), and extra- and intracorporeal lithotripsy, interventional sialendscopy and sialendoscopy-assisted surgery are used as minimally invasive, conservative procedures for functional preservation of the affected gland. We evaluated the results of our long-term experience in the management of paediatric obstructive salivary disorders...

The present research deals with the clinical and social problems present during linguistic and cognitive development of deaf children. Currently, the development of Theory of Mind represents an important research field in deafness studies. These international studies highlighted a significant alteration in the development of Theory of Mind in deaf children compared to normal hearing children, especially in cases of congenital or preverbal hearing loss. In particular, the research focuses on the skills of deaf children in recognising emotions and desires, through both perceptive and cognitive methods, by evaluation of psycho-cognitive skills of children with severe hearing loss using a set of questions to be administered to hearing loss patients...

Coordination in groups faces a sub-optimization problem and theory suggests that some randomness may help to achieve global optima. Here we performed experiments involving a networked colour coordination game in which groups of humans interacted with autonomous software agents (known as bots). Subjects (n = 4,000) were embedded in networks (n = 230) of 20 nodes, to which we sometimes added 3 bots. The bots were programmed with varying levels of behavioural randomness and different geodesic locations...

ABSTRACT: An experimental study has been conducted to visualise the instantaneous streamwise and spanwise flow patterns of a normal shock wave impinging over a rounded contour bump in a Mach 1.3 free-stream. A quartz-made transparent shock generator was used, so that instantaneous images could be captured during the oil-flow visualisation experiments. Fluorescent oil with three different colours was used in the surface oil-flow visualisation experiment to enhance the visualisation of flow mixing and complicated flow features that present in the flow field...

When mimicry imposes costs on models, selection may drive the model's phenotype to evolve away from its mimic. For example, brood parasitism often drives hosts to diversify in egg appearance among females within a species, making mimetic parasitic eggs easier to detect. However, when a single parasite species exploits multiple host species, parasitism could also drive host egg evolution away from other co-occurring hosts, to escape susceptibility to their respective mimics. This hypothesis predicts that sympatric hosts of the same parasite should partition egg phenotypic space (defined by egg colour, luminance and pattern) among species to avoid one another...

Well-controlled quantum devices with their increasing system size face a new roadblock hindering further development of quantum technologies. The effort of quantum tomography-the reconstruction of states and processes of a quantum device-scales unfavourably: state-of-the-art systems can no longer be characterized. Quantum compressed sensing mitigates this problem by reconstructing states from incomplete data. Here we present an experimental implementation of compressed tomography of a seven-qubit system-a topological colour code prepared in a trapped ion architecture...

Many plants defend themselves against herbivores by chemical deterrents in their tissues and the presence of such substances in floral nectar means that pollinators often encounter them when foraging. The effect of such substances on the foraging behaviour of pollinators is poorly understood. Using artificial flowers in tightly-controlled laboratory settings, we examined the effects of the alkaloid nicotine on bumblebee foraging performance. We found that bumblebees confronted simultaneously with two equally rewarded nicotine-containing and nicotine-free flower types are deterred only by unnaturally high nicotine concentrations...

INTRODUCTION: Stroke is defined as an abrupt onset of neurologic deficit due to vascular cause. It is one of the leading causes of mortality and morbidity all over the world making early diagnosis and treatment inevitable. Lesions of extra cranial carotid arteries are implicated in majority of cases of acute ischemic stroke. Carotid Doppler is a non-invasive imaging technique, with sensitivity approaching that of angiography. Computed Tomography (CT) plays a major role to assess the site and nature of the lesion in patients with acute ischemic stroke...

INTRODUCTION: Vulvovaginal Candidiasis (VVC) is a common medical health problem of adult women. It is most commonly caused by Candida albicans. But there is a change in fungal profile. Sabouraud's Dextrose Agar (SDA) is the most common culture medium used where mixed fungal infection may be missed. It can be detected easily by using chromogenic culture medium. AIM: To know the fungal profile of vulvovaginal candidiasis using Candida CHROMagar and antifungal susceptibility pattern in patients attending tertiary care hospital...

Acute scrotum is one of the most common urologic emergencies in children and adolescents. This condition involves acute testicular pain, which is often accompanied by scrotal swelling and erythema. It is most important to distinguish between cases that require immediate surgery and those that can be treated conservatively. As patient history and physical findings may not always be unequivocal, ultrasound with Colour-Coded Doppler Sonography is the imaging modality of choice for further evaluation. Testicular torsion and other differential diagnoses such as epididymitis, appendiceal torsion, intratesticular haematoma after trauma, or complicated inguinal hernia have to be considered...

Ultrasound examination of the kidneys with grey-scale imaging and colour Doppler ultrasound is the most common renal imaging modality. A few years ago, contrast-enhanced ultrasound (CEUS) emerged as a non-invasive perfusion imaging modality to evaluate the renal vessels and microvascularisation. These contrast media contain intravenous microbubbles (sulfur hexafluoride), which have no deleterious effect on renal function. Being free of iodine, they also pose no risk for the thyroid gland. CEUS of the kidneys is mainly used for the evaluation of renal cysts and the analysis of renal lesions suspicious for malignancy...

Mirror Self-Recognition (MSR) unveils complex cognitive, social and emotional skills and it has been found only in humans and few other species, such as great apes, dolphins, elephants and magpies. In this pilot study, we tested if horses show the capacity of MSR. Four subjects living socially under naturalistic conditions were selected for the experiment. We adopted the classical mark test, which consists in placing a coloured mark on an out-of-view body part, visible only through mirror inspection. If the animal considers the image as its own, it will use its reflection to detect the mark and will try to explore it...

Natural melanins are biocompatible conductors with versatile functionalities. Here, we report fabrication of multifunctional poly(vinyl alcohol)/melanin nanocomposites by layer-by-layer (LBL) assembly using melanin nanoparticles (MNPs) directly extracted from sepia officinalis inks. The LBL assembly offers facile manipulation of nanotextures as well as nm-thickness control of the macroscale film by varying solvent qualities. The time-resolved absorption was monitored during the process and quantitatively studied by fractal dimension and lacunarity analysis...
