Gian L Nicolosi
International guidelines indicate that interventional closure of left atrial appendage and patent foramen ovale may be considered in selected patients for stroke prevention. These procedures appear, however, from the published literature, at high risk of uselessness and futility in the single case, if not even capable to induce harm and adverse events. In fact, all reported systematic reviews and meta-analyses have not shown in a convincing manner the superiority of these procedures in stroke prevention, taking into account the occurrence of possible complications also, as compared with alternative medical treatment...

Negative allosteric modulators (NAM) of metabotropic glutamate receptor 5 (mGluR5) have been implicated as potential pharmacotherapy for a number of psychiatric diseases including anxiety and depression. Most of the mGluR5 NAM clinical candidates can be characterized by the central acetylenic moiety that connects the terminal pharmacophores. Identification of a sulfoquinoline hit via high throughput screening (HTS) followed by optimization provided a 4-phenyl-3-aryl-sulfoquinoline lead compound with the minimal pharmacophore...

Fernando Gómez
The marine dinoflagellate Erythropsidinium possesses an ocelloid, the most elaborate photoreceptor organelle known in a unicellular organism, and a piston, a fast contractile appendage unknown in any other organism. The ocelloid is able to rotate, often before the cell swims. The ocelloid contains lenses that function to concentrate light. The flagellar propulsion is atrophied, and the piston is responsible for locomotion through successive extensions and contractions. During the 'locomotion mode', the contraction is ~4 times faster than the extension...

Although insecticide spray droplets will potentially impinge on many exoskeletal body regions, traditional mosquito topical bioassays focus insecticide application to the mesothoracic pleural or dorsal area. Concentrations of permethrin and malathion found in droplets from ultra-low volume and low-volume sprays were evaluated for efficacy against adult Culex quinquefasciatus using a topical application bioassay. Results document nonuniform insecticide sensitivity across body regions, which has not been previously assessed in mosquitoes...

The objective of this study was to give an overview of a rare case of tuberculosis of the left fallopian tube in postmenopausal women. It is known that the isolated tuberculous salpingitis without spreading to the endometrium is extremely rare case. In our case, it simulated a cancer of appendages at the late stages that were proved by the increased level of CA-125. This fact as well as the macroscopic image of the left fallopian tube was incorrectly considered by the clinicians as a malignant neoplasm of fallopian tube...

Pulmonary embolism (PE) is a common, potentially fatal thrombotic disease. Atrial fibrillation (AF), the most common arrhythmia, may also lead to thromboembolic complications. Although initially appearing as distinct entities, PE and AF may coexist. The direction and extent of this association has not been well characterized. We performed a search of PubMed, Scopus, and the Cochrane Database of Systematic Reviews for publications that reported coexisting AF in patients with PE, or vice versa, to provide a systematic overview of pathophysiological and epidemiological aspects of this association (last search: October 13, 2016)...

The development of vertebrate appendages, especially the limb and feather buds are orchestrated by numerous secreted signalling molecules including Sonic Hedgehog, Bone Morphogenetic Proteins, Fibroblast Growth Factors and Wnts. These proteins coordinate the growth and patterning of ectodermal and mesenchymal cells. The influence of signalling molecules is affected over large distances by their concentration (morphogen activity) but also at local levels by the presence of proteins that either attenuate or promote their activity...

BACKGROUND: Transesophageal echocardiography (TEE) remains the gold standard for exclusion of left atrial appendage (LAA) thrombus in patients scheduled for direct electrical cardioversion (DEC) or atrial fibrillation (AF) ablation. Recently, intracardiac echocardiography (ICE) of the pulmonary artery (PA) has been shown to provide excellent LAA images and to be useful in verification of equivocal TEE findings. HYPOTHESIS: ICE of the PA may have a role in detecting false-positive TEE results...

Random skin flaps are commonly used in plastic and reconstructive surgery for patients suffering from severe or large scale wounds or in facial reconstruction. However, skin flaps are sometimes susceptible to partial or complete necrosis at the distal parts of the flaps due to insufficient blood perfusion in the defected area. In order to improve neovascularization in skin flaps, we developed an exogenous growth factor (GF) delivery platform comprised of coacervate-coated poly(lactic-co-glycolic acid) (PLGA) nanofibers...

BACKGROUND: Amputations in general and amputations of upper extremities, in particular, have a major impact on patients' lives. There are only a few long-term follow-up reports of patients after macro-replantation. We present our findings in contrast with the existing literature. METHODS: Sixteen patients with traumatic macro-amputation of an upper extremity were eligible for inclusion in this study. Altogether, the patients underwent replantation in 3 institutions between 1983 and 2011...

A new species of Helicopsyche subgenus Feropsyche from Chapada Diamantina is diagnosed, described, and illustrated. Helicopsyche catoles n. sp. is easily distinguished from congeners by the following features: inferior appendages clavate, each bearing a posteroventral projection with 2-4 setae in lateral view, and tergum X with a notched apex and a short setal row along its length in dorsal view. Additionally, new records from Chapada Diamantina, Bahia, Brazil, are presented. A total of 31 species, including the new species, are recorded, belonging to 14 genera and 8 families...

A major challenge in evolutionary biology is explaining the origins of complex phenotypic diversity. In animal communication, complex signals may evolve from simpler signals because novel signal elements exploit pre-existing biases in receivers' sensory systems. Investigating the shape of female preference functions for novel signal characteristics is a powerful, but underutilized, method to describe the adaptive landscape potentially guiding complex signal evolution. We measured female preference functions for characteristics of acoustic appendages added to male calling songs in the grasshopper Chorthippus biguttulus, which naturally produces only simple songs...

While oral anticoagulants (OACs) remains the main strategy of prevention of thromboembolic event in patients with atrial fibrillation (AF), left atrial appendage closure (LAAC) has become an alternative recently. The concept of this technique is based on the understanding that in more than 90% non-valvular AF patients, the thrombi form in the left atrial appendage (LAA), so excluding the LAA from the systemic circulation can prevent stroke or peripheral arterial embolization. To achieve this goal, novel trans-catheter techniques have been developed to either occlude the LAA endocardially or ligate the LAA epicardially...
