Ventilation in cities is crucial for the well being of their inhabitants. Therefore, local 1 governments require air ventilation assessments (AVAs) prior to the construction of new buildings. In 2 a standard AVA, however, only neutral stratification is considered, although diabatic and particularly 3 unstable conditions may be observed more frequently in nature. The results presented here indic...

Sir , Individuals a¡ected byDown's syndrome sometimes showpeculiar dermatoses; some of them, such as palpebral syringomas (1), seem to occur with a particular frequency in this population, others, less frequent, are however characteristic of Down's syndrome, e.g. elastosis perforans serpiginosa (2) and milia-like idiopathic calcinosis (3). We report here on 4 patients with Down's syndrome and a...

Sleep has been shown to subtly disrupt the spatial organization of functional connectivity networks in the brain, but in a way that largely preserves the connectivity within sensory cortices. Here we evaluated the hypothesis that sleep does impact sensory cortices, but through alteration of activity dynamics. We therefore examined the impact of sleep on hemodynamics using a method for quantifyi...

CASE REPORT The case is presented on a 63-year-old patient with Terson's syndrome who complained of loss of visual acuity. The optical coherence tomography showed macular atrophy. DISCUSSION The patient developed macular atrophy probably secondary to macular hemorrhage caused by the rupture of a cerebral aneurysm.

Purpose To explore the association between presence of subretinal drusenoid deposits (SDD) at baseline in eyes with neovascular age-related macular degeneration (nAMD) with the development of macular atrophy (MA) during anti-vascular endothelial growth factor (VEGF) therapy. Methods There were 74 eyes without pre-existing MA receiving anti-VEGF therapy for nAMD for 2 years or longer analyzed....

A rapid and deep inspiration triggers a sympathetically mediated transient vasoconstriction of skin arterioles (inspiratory gasp vascular response, IGVR). Because the IGVR has been most often measured and studied in skin that is rich in arteriovenous anastomoses (AVAs), such as the palmar aspect of the distal phalanx or plantar aspect of the toes, there is little information on its features in ...

Elastosis perforans serpiginosa (EPS) is a rare reactive perforating dermatosis that is characterized by the transepidermal elimination of abnormal elastic fibers. Penicillamine, which is one of the clear triggers for EPS, is a heavy metal chelator that is primarily used for disorders such as cystinuria and Wilson's disease. It may cause alterations in the dermal elastic tissue such as pseudo-p...

Dysosteosclerosis (DSS) is the form of osteopetrosis distinguished by the presence of skin findings such as red-violet macular atrophy, platyspondyly and metaphyseal osteosclerosis with relative radiolucency of widened diaphyses. At the histopathological level, there is a paucity of osteoclasts when the disease presents. In two patients with DSS, we identified homozygous or compound heterozygou...

A major goal of neuroscience studies is to identify the neurons and molecules responsible for memory. Mechanosensory habituation in Caenorhabditis elegans is a simple form of learning and memory, in which a circuit of several sensory neurons and interneurons governs behavior. However, despite the usefulness of this paradigm, there are hardly any systems for rapid and accurate behavioral genetic...
