Eight-membered heterocycles with two heteroatoms in a 1,5-relationship of interest in medicinal chemistry

2020

Abstract This review deals with 1,5-diheterocines that exhibited biological properties and covers comprehensively the literature from 2007 to the end of February 2019. Among the six possible heterocyclic systems belonging to the eight-membered rings with two heteroatoms, N, O, and S, five had derivatives showing pharmacological activities: 1,5-diazocines, 1,5-oxazocines, 1,5-thiazocines, 1,5-dioxocins, and 1,5-dithiocins. Instead, literature reported no articles dealing with 1,5-oxathiocins of interest in medicinal chemistry. In addition to uncondensed derivatives, 1,5-diheterocines fused to five- and six-membered carbocycles or heterocycles are covered. Bridged 1,5-diheterocines are covere…

How to diagnose and treat abdominal compartment syndrome after endovascular and open repair of ruptured abdominal aortic aneurysms

2014

Intra-abdominal hypertension (IAH) and abdominal compartment syndrome (ACS) are frequently encountered in patients treated for ruptured abdominal aortic aneurysms (rAAA) and carry a high morbidity and mortality risk. Despite these facts, IAH/ACS are still overlooked by many physicians, timely diagnosis is missed and treatment often inadequate. All staff involved in the treatment of rAAA should be aware of the risk factors predicting IAH/ACS, the profound implications and derangements on all organ systems, the clinical presentation, the appropriate measurement of intra-abdominal pressure to detect IAH/ACS and the current treatment options for these detrimental syndromes. This comprehensive r…

Angular Trapping of Anisometric Nano-Objects in a Fluid

2012

We demonstrate the ability to trap, levitate, and orient single anisometric nanoscale objects with high angular precision in a fluid. An electrostatic fluidic trap confines a spherical object at a spatial location defined by the minimum of the electrostatic system free energy. For an anisometric object and a potential well lacking angular symmetry, the system free energy can further strongly depend on the object's orientation in the trap. Engineering the morphology of the trap thus enables precise spatial and angular confinement of a single levitating nano-object, and the process can be massively parallelized. Since the physics of the trap depends strongly on the surface charge of the objec…

Microwear textures associated with experimental near-natural diets suggest that seeds and hard insect body parts cause high enamel surface complexity…

2022

In mammals, complex dental microwear textures (DMT) representing differently sized and shaped enamel lesions overlaying each other have traditionally been associated with the seeds and kernels in frugivorous diets, as well as with sclerotized insect cuticles. Recently, this notion has been challenged by field observations as well as in vitro experimental data. It remains unclear to what extent each food item contributes to the complexity level and is reflected by the surface texture of the respective tooth position along the molar tooth row. To clarify the potential of seeds and other abrasive dietary items to cause complex microwear textures, we conducted a controlled feeding experiment wi…

Repeatability of in-vitro optical quality measurements of intraocular lenses with a deflectometry technique effect of the toricity

2018

Aim To evaluate the repeatability of an optical device for measuring the Zernike coefficients of toric intraocular lenses (IOLs) and assess whether its toricity has any impact in its repeatability. Methods An experienced technician used the NIMO TR1504 to measure the Zernike coefficients 30 times for an aperture of 4.50 mm for all lenses included. The IOLs included were divided into two group: toric and non-toric ones. The cylindrical powers of the toric lenses included in the present study were 1.00, 1.50, 2.25, 3.00 and 3.75 D. Finally, the repeatability of the NIMO TR1504 was described in terms of within subject standard deviation (Sw) and repeatability limit. Results The Sw was smaller …

The metabolites of the genus onopordum (asteraceae): Chemistry and biological properties

2011

Onopordum is an interesting genus belonging to the tribe Cardueae (Asteraceae family), and the species of this genus are used as food and in the popular medicine of several countries. The present paper reviews all the metabolites present in all the species of this genus, reported up to 2009, and several chemotaxonomic consideration have been made. Furthermore, the occurrence in other genus, the spectral data, the synthetic approaches, the chemical modifications and the biological properties of the sesquiterpenes of genus Onopor- dum have been reviewed.

OPERADS AND JET MODULES

2005

Let $A$ be an algebra over an operad in a cocomplete closed symmetric monoidal category. We study the category of $A$-modules. We define certain symmetric product functors of such modules generalising the tensor product of modules over commutative algebras, which we use to define the notion of a jet module. This in turn generalises the notion of a jet module over a module over a classical commutative algebra. We are able to define Atiyah classes (i.e. obstructions to the existence of connections) in this generalised context. We use certain model structures on the category of $A$-modules to study the properties of these Atiyah classes. The purpose of the paper is not to present any really de…

Forensic Inspections in the Time of Covid-19

2021

The global pandemic of COVID-19 has impacted the entire world in ways that were unimaginable months ago. It has changed how professionals work and interact with one another. To ensure the safety of experts and attorneys, also forensic inspection procedures must evolve, while still providing a reliable foundation for an expert testimony, relevant to the task at hand. Traditional field inspections require attendees to be physically present and generally in close proximity. Inspecting artifacts may also require that individual components be serially examined by multiple experts, which increases the risk of transmitting the disease. The authors propose a new approach to forensic inspections aim…
