Septate uterus: nosographic overview and endoscopic treatment
2014
To comment on the prevalence, diagnosis, and treatment of the septate uterus, with special reference to hysteroscopic metroplasty and its effect on reproductive outcome, we searched publications in PubMed and Embase. Original articles, meta-analysis, reviews, and opinion articles were selected. The studies suggest that the prevalence of the septate uterus is increased in women with repeated pregnancy loss and infertility. Reliable diagnosis depends on accurate assessment of the uterine fundal contour and uterine cavity by means of magnetic resonance and three-dimensional ultrasound. Pertinent published data comparing pregnancy outcome before and after hysteroscopic metroplasty indicated a m…
Selective encapsulation of a chloride anion in a 1H-pyrazole Cu2+ metallocage
2021
A self-assembled metallobox from copper(ii) and two macrocycles containing 1H-pyrazole ligands has been prepared. The internal cavity of the box is able to selectively encapsulate a single chloride anion over any other halide anion.

Cavity-aided quantum parameter estimation in a bosonic double-well Josephson junction
2014
We describe an apparatus designed to make non-demolition measurements on a Bose-Einstein condensate (BEC) trapped in a double-well optical cavity. This apparatus contains, as well as the bosonic gas and the trap, an optical cavity. We show how the interaction between the light and the atoms, under appropriate conditions, can allow for a weakly disturbing yet highly precise measurement of the population imbalance between the two wells and its variance. We show that the setting is well suited for the implementation of quantum-limited estimation strategies for the inference of the key parameters defining the evolution of the atomic system and based on measurements performed on the cavity field…
Cavity optomechanics mediated by a quantum two-level system
2015
Coupling electromagnetic waves in a cavity and mechanical vibrations via the radiation pressure of photons is a promising platform for investigations of quantum–mechanical properties of motion. A drawback is that the effect of one photon tends to be tiny, and hence one of the pressing challenges is to substantially increase the interaction strength. A novel scenario is to introduce into the setup a quantum two-level system (qubit), which, besides strengthening the coupling, allows for rich physics via strongly enhanced nonlinearities. Here we present a design of cavity optomechanics in the microwave frequency regime involving a Josephson junction qubit. We demonstrate boosting of the radiat…

Thymus essential oil extraction, characterization and incorporation in phospholipid vesicles for the antioxidant/antibacterial treatment of oral cavi…
2018
The aim of the work was to extract, characterize, and formulate Thymus capitatus (Tymbra capitata) essential oil in phospholipid vesicles: liposomes, glycerosomes and Penetration Enhancer-containing Vesicles (PEVs). The steam-distilled essential oil was mainly composed of carvacrol. The oil was mixed with lecithin and water to produce liposomes, or different ratios of water/glycerol or water/propylene glycol (PG) to produce glycerosomes and PG-PEVs, respectively. Cryo-TEM showed the formation of unilamellar, spherical vesicles, and light scattering disclosed that their size increased in the presence of glycerol or PG, which improved long-term stability. The formulations were highly biocompa…
Effect of depth of neuromuscular blockade on the abdominal space during pneumoperitoneum establishment in laparoscopic surgery.
2015
To evaluate the effect of neuromuscular blockade (NMB) upon the abdominal space during pneumoperitoneum establishment in laparoscopic surgery, comparing moderate NMB and deep NMB.Prospective, randomized, crossover clinical trial.Operating room.Seventy-six American Society of Anesthesiologists 1 to 2 patients scheduled for elective laparoscopic surgery.Two independent evaluations were performed at the establishment of pneumoperitoneum for a preset intraabdominal pressures (IAPs) of 8 and 12 mm Hg, both during moderate NMB (train-of-four count, 1-3) and deep NMB (posttetanic count,5). Rocuronium was used to induce NMB, and sugammadex was used for reversal.We evaluated (i) the volume of CO2 in…
Surgical Advances in the Treatment of Abdominal Wall Hernias
2015
In the last two decades, the surgery of the abdominal wall has experienced an important development from being considered a matter of little interest for general surgeon, to having a greater presence at scientific meetings and to being increasingly prominent in the specialist training in surgery. In 1990 the plastic surgeon Oscar Ramirez published a method to repair defects in the abdominal wall that called “Component Separation Technique” thereafter general surgeons fixed his attention on the techniques of autoplastic repair of the abdominal wall that had already developed throughout the twentieth century. This interest grows with the emergence of new prosthesis and the use of laparoscopic…
