Characterization of a tetradentate ONNO Schiff base ligand namely (1, 1′- (pyridine-2, 3-dimethyliminomethyl) naphthalene-2, 2′-diol) and hereafter denotes as “SL″ and selected metal complexes including Mn(II), Fe(II), Co(II) and Cd(II) as a central metal was studied.In this paper, the calculation was done to determine the magnetic exchange of the studied molecules, Schiff base complexes via DFT calculations. Using the ZORA approach with the BP86 functionals and appropriate basis set def2-tzvp and Coulomb fitting, the optimized geometries were obtained with reliable accuracy and precision.The dipole moment was calculated. The EPR parameters were also reported.

Despite adjuvant radiotherapy, rates of recurrences of endoscopically operated nasal intestinal-type adenocarcinomas (ITAC) have not been improved in successive series. To better understand how to improve local control, we aimed to investigate the site of local recurrences of ITACs.Retrospective study in a reference center in sinonasal malignancies. For all patients with a local recurrence, radiotherapy plans were retrieved and compared to the delineation of local recurrences.Of 63 patients, 54 underwent adjuvant radiotherapy of which 14 (25.9%) had a local recurrence. Eleven of them had their onset in an optimally irradiated area. Difficulty to dissect the cribriform plate and/or the lateral lamina was reported for 11 patients with local recurrences in the operative reports (p 0.0001).Most of recurrences arose in an optimally irradiated area. A close cooperation between surgeons and radiotherapists is required to define areas at risk and adapt treatment.

Transport infrastructure connectivity plays an important role in promoting trade between two countries, and creates an impetus for economic development and international cooperation. A synchronous, modern, flexible and appropriate transport infrastructure connectivity system promotes trade, boosts productivity and efficiency of cooperation, and promotes linkages between countries. The Mekong–India Economic Corridor (MIEC) is considered a bridge between India and the Mekong sub-region, including the CLMV countries (Cambodia, Laos, Myanmar, Vietnam). Despite the position of an end point in the connectivity system, Vietnam is an important factor in India’s Look East strategy. Enhancing transport infrastructure connectivity through the MIEC will help promote Vietnam–India comprehensive strategic partnership effectively. The paper, based on objective assessment, presents an in-depth perspective on the transport infrastructure connectivity between Vietnam and India through the MIEC and figures out the bottlenecks in connectivity, cooperation and development between the two countries.

Before 2009, most central banks conducted their monetary policy with the ultimate goals of promoting price stability, economic growth and full employment. However, the 2009 financial crisis demonstrated that these goals are not enough to maintain a stable financial arena. So, aside from those objectives, the objective of financial stability is also of interest to central banks when implementing monetary policy. In this study, the authors explore the influence of monetary policy on the stability of commercial banks in Vietnam – an emerging economy. The study uses the dataset of the Vietnamese commercial banks from 2008 to 2019, applying SGMM estimations and checking their robustness with a Bayesian approach. The results show that, in recent years, the SBV has effectively implemented monetary policy to ensure banks’ stability in Vietnam. In particular, money supply M2 has positively impacted the stability of commercial banks. Also, the results imply that the ratio of loan to total assets, the ratio of cost operating to income operating, as well as CPI, correlate negatively with bank stability. The study did not find any impact of bank size or GDP on bank stability during the research period. Based on these results, the SBV should manage an optimal level of money supply M2 to guarantee efficient economic operations in general and maintain bank stability in particular, and should avoid high inflation.

Objectives The impacts of partial laryngectomy on sleep‐disordered breathing were rarely investigated and reported in a limited number of patients. The aim of this study was to assess the prevalence of obstructive sleep apnea‐hypopnea syndrome (OSAHS) in patients with partial laryngectomy. Study design Case series. Methods All patients undergoing partial laryngectomy by open approach (frontolateral vertical partial laryngectomy and supracricoid horizontal partial laryngectomy) for squamous cell carcinoma of the larynx between January 2006 and December 2019 were enrolled. Listed patients were contacted via telephone to propose participating in the study and plan a sleep study: self‐assessments of sleep quality using the Pittsburgh Sleep Quality Index (PSQI) following a home sleep recording using respiratory polygraphy. Daytime sleepiness was also self‐assessed by using the Epworth sleepiness scale. Results Twenty patients with sleep record were included to the analyses. There were 11/20 patients (55%) diagnosed with moderate to severe OSASH. No relationship between OSAHS severity and age as well as body mass index (BMI) was observed. The Epworth sleepiness score was not necessarily high in patients with moderate/severe OSASH. Type of partial laryngectomy did not influence apnea‐hypopnea index (AHI) results. There was no difference in terms of age, BMI, gender, type of partial laryngectomy, and the presence of adjuvant radiotherapy between two groups AHI, The aim of this study was to assess the prevalence of obstructive sleep apnea‐hypopnea syndrome (OSAHS) in patients with partial laryngectomy. There were 11/20 patients (55%) diagnosed moderate to severe OSASH. No relationship between OSAHS severity and age as well as body mass index (BMI) was observed. The Epworth sleepiness score was not necessarily high in patients with moderate/severe OSASH. Type of partial laryngectomy did not influence apnea‐hypopnea index (AHI) results. A sleep study screening for OSAHS should be considered in patients with partial laryngectomy in order to improve their quality of sleep and quality of life although absence of daily sleepiness and obesity.

Bank stability is a goal that bank managers aim for in addition to the goal of maximizing shareholder value. To achieve this goal, commercial banks have applied various solutions, including corporate governance because corporate governance plays an important role in the business activities of an enterprise in general as well as in that of a commercial bank in particular. The purpose of this paper is to investigate the impact of corporate governance on the stabilities of Vietnamese commercial banks in the period from 2009 to 2020. Using hand-collected data from 25 commercial banks in Vietnam, by system GMM estimation and the Bayesian Mixed-Effects approach, the paper identifies the characteristics of corporate governance affecting bank stability. Board size, women board members, and board members’ education have a positive impact, and dependent board and foreign board members have a negative impact on bank stability. Our findings show important evidence for an emerging country, such as Vietnam. From the empirical results, the authors suggest several recommendations to maintain and enhance bank stability in the future time.

Neuromuscular blocking agents (NMBA) facilitate endotracheal intubation and reduce related laryngeal morbidity. However, NMBA interfere with intraoperative neuromonitoring amplitudes during thyroidectomy. The goal of this study was to evaluate the impact of rocuronium used for tracheal intubation on early intraoperative neuromonitoring vagal amplitudes observed during first thyroid lobe dissection. This is an observational pharmacoepidemiological study with prospective data collection and retrospective analysis. During the study period, all consecutive patients who underwent thyroid surgery with neuromonitoring were included. Patients underwent endotracheal intubation either using a single dose of rocuronium (NMBA group) or without NMBA (NMBA-free group) according to the anesthesiologist’s preference. Six hundred six patients were included (213 NMBA and 393 NMBA-free group patients). At V1, 39 patients (18%) in the NMBA group had an amplitude

Resume Les difficultes a corriger les deformations de la cloison nasale avec les techniques classiques de Killian ou de Cottle et leurs derivees ont ete soulignees ces dernieres annees par la proposition de techniques telles que la septoplastie extracorporelle ou l’utilisation de greffons apposes divers pour contrecarrer les deformations refractaires du cartilage quadrangulaire. Les deformations naturelles de la cloison nasale resultent en fait d’un conflit de croissance entre le cartilage quadrangulaire, la lame perpendiculaire de l’ethmoide et le vomer qui ont chacun une origine evo-devo differente. La septoplastie par desarticulation permet avec constance de restaurer une cloison plane en levant completement le conflit de la croissance septale. La preservation du cartilage quadrangulaire est indispensable au maintien de la stabilite de l’edifice nasal a condition de respecter 1) l’evasement lateral du bord superieur des deux cartilages septolateraux qui le composent et le suspendent a la voute de l’orifice piriforme et 2) la hauteur de son bord anterieur. Le bord anterieur est en effet toujours au moins assez haut (sauf dans des cas de fractures ou de malformations) pour projeter le dorsum nasal retrolobulaire proportionnellement a la hauteur des cartilages alaires quand il est repositionne sur sa base premaxillaire naturelle.

Resume Buts La chirurgie endoscopique endonasale requiert de nombreuses competences. Afin d’entrainer les chirurgiens juniors a l’acquisition des competences essentielles en chirurgie endoscopique et d’evaluer leur progression, un programme d’apprentissage progressif a ete developpe sur un simulateur chirurgical (Cyrano). L’objectif principal de cette etude etait d’etablir la validite de construction de ces exercices et d’affiner les criteres objectifs permettant d’evaluer le niveau des etudiants. Materiel et methodes Trente volontaires de differents niveaux d’experience en chirurgie endoscopique endonasale ont ete evalues en aveugle sur 4 modules, selon des criteres objectifs et subjectifs. Resultats Dix participants de niveau debutant, 11 de niveau intermediaire et 9 experts ont ete inclus. Pour chaque exercice, au moins un critere etait discriminant du niveau d’expertise. Cependant, l’interpretation d’un critere pris isolement est difficile : l’evaluation doit plutot s’appuyer sur des scores composites, qui refletent mieux le niveau des participants et les resultats ponderes permettaient de discriminer les groupes. Les criteres pertinents et leurs valeurs de reference sont specifiques de chaque exercice. Les validites apparentes et de contenu ont ete notees respectivement a 3,92/5 et 4,59/5 (echelle de Likert a 5 niveaux). Conclusion Les validites de construction, validite apparente et validite de contenu des modules presentes ont ete verifiees. La plupart des modules testes etaient anatomiquement non realistes, mais tous etaient juges par les participants comme tres pertinents pour la formation chirurgicale.

Purpose Endoscopic endonasal surgery requires many skills: a learning program was developed with progressive steps, on a surgical simulator (Cyrano) designed to train junior surgeons in the acquisition of basic endoscopic surgery skills and to assess their progress. The main objective of this study was to establish the construct validity of these exercises and to refine objective criteria to establish students’ level. Material and methods Thirty volunteers with varying experience in endoscopic endonasal surgery were blindly evaluated on 4 modules according to objective and subjective criteria. Results Ten beginner, 11 intermediate and 9 expert level participants were included. For each exercise, at least one criterion was discriminant for level of expertise. Weighted scores succeeded in discriminating groups. Interpretation of a single criterion must remain cautious and evaluation should rather rely on composite scores, which better reflect the participants’ level. Useful criteria and their reference values are specific of each exercise. Face and content validity were rated at 3.92/5 and 4.59/5 respectively (5-level Likert scale). Conclusion The construct/face/content validity of the proposed modules have been verified. Most of the modules tested here were physically not realistic, but they were all rated as highly relevant for surgical training by the participants.

Herein, we demonstrate that 3-mercaptopropionate capping agents on CdS quantum dot surfaces could serve as proton shutters and localize protons near the active sites towards efficient photocatalytic CO2 reduction. A series of water-soluble 3-mercaptopropionic acid (MPA)-capped CdS quantum dots with different molar ratios of MPA : Cd (denoted as CdS-xA) are successfully synthesized via an aqueous synthesis, promoting the formation of surface Cd atoms as active sites in photocatalytic CO2 reduction. The enhanced photocatalytic activity of functional CdS quantum dots could be attributed to the cooperative interaction between localized protons and surface Cd atoms, which behave as a Lewis acid and Lewis base, respectively. The representative CdS-1A exhibits the highest CO generation rate of ∼16 μmol h−1 with apparent quantum yield of 4.17% at 420 nm under optimized conditions, which is one of the highest values reported for CdS-based materials. This work aims to understand the important role of protons localized near active sites, which can promote efficient photocatalytic CO2 to CO reduction.

Nowadays, charge separation and efficient solar-light absorption are the main challenges in the photoreduction of CO2. Although significant efforts have been made to overcome these issues, including the use of cocatalysts and doping, photocatalysts still suffer from low photocatalytic activity and stability. Herein, the localized surface plasmonic resonance (LSPR) effect of Au nanoparticles deposited into the zeolitic imidazolate framework (ZIF-67) was investigated for the photoreduction of CO2. Different Au loadings in ZIF were prepared and their effects were studied on photocatalytic performance. Plasmonic Au nanoparticles (PNPs) in the size range of 30–40 nm improved visible-light absorption, enhanced charge separation, and played an important role in selectivity. A volcano relationship of plasmonic Au NPs with methanol and ethanol generation was found, along with the deposition of plasmonic Au nanoparticles. A total yield of 2.5 mmol g–1 h–1 of methanol and 0.5 mmol g–1 h–1 of ethanol were obtained, which are the highest values compared to those reported in other studies. Finally, our results revealed that Au PNPs have a significant impact on the selectivity and photocatalytic activity of ZIF-67 for the photoreduction of CO2 and could be a promising alternative toward designing plasmonic reticular materials.

Here, we present a three-dimensional two-color dual-particle tracking (3D-2C-DPT) technique that can simultaneously localize two spectrally distinct targets in three dimensions with a time resolution down to 5 ms. The dual-targets can be tracked with separation distances from 33 to 250 nm with tracking precisions of ~15 nm (for static targets) and ~35 nm (for freely diffusing targets). Since each target is individually localized, a wealth of data can be extracted, such as the relative 3D position, the 2D rotation, and the separation distance between the two targets. Using this technique, we turn a double-stranded DNA (dsDNA)-linked dumbbell-like dimer into a nanoscopic optical ruler to quantify the bending dynamics of nicked or gapped dsDNA molecules in free solution by manipulating the design of dsDNA linkers (1-nick, 3-nt, 6-nt, or 9-nt single-strand gap), and the results show the increase of k(on) (linear to bent) from 3.2 to 10.7 s(−1). The 3D-2C-DPT is then applied to observe translational and rotational motions of the landing of an antibody-conjugated nanoparticle on the plasma membrane of living cells, revealing the reduction of rotations possibly due to interactions with membrane receptors. This study demonstrates that this 3D-2C-DPT technique is a new tool to shed light on the conformational changes of biomolecules and the intermolecular interactions on plasma membrane.

The use of tetracycline hydrochloride (TCH) for veterinary, human therapy, and agriculture has risen in the past few decades, making it to become one of the most exploited antibiotics. However, TCH residue in the environment is causing issues related to the evolution of antibiotic-resistant bacteria. To address such a problem, photodegradation offers a potential solution to decompose these pollutants in wastewater and thereby mitigates negative environmental impacts. In this context, the research focuses on the use of the rare-earth metal oxide samarium orthovanadate (SmVO

Sudden loss of smell is a very common symptom that can be observed in two-thirds of patients with Covid-19, and may be the only symptom of this disease. A study has demonstrated that 80% of infected patients have sudden loss of smell without nasal obstruction. This suggests that anomalies of the olfactory epithelium are a key element of pathogenesis and local involvement. Management of odor disorders related to Covid-19 is still being debated.
