Drug Promotions Between Ethics, Regulations, and Financial Interests.

Background: The promotion of the latest medicines produced by the pharmaceutical industry is an important issue both from an ethical point of view (the level of accessibility, the way research is carried out) and from the point of view of marketing and especially from the lobbying issues raised.

Areas Of Uncertainty: The ethical dilemmas raised by the promotion of new drugs revolve between the need to discover new molecules important for treating a wide range of diseases and the need to establish a battery of ethical rules, absolutely necessary for regulations in the field to be compliant with all ethical principles.

Data Sources: A literature search was conducted through PubMed, MEDLINE, Plus, Scopus, and Web of Science (2015-2023) using combinations of keywords, including drugs, medical publicity, and pharma marketing plus ethical dilemma.

Prognostic Significance of Multifactorial Analysis in Complex Cervical Aero-Digestive Trauma Cases.

: In the context of complex aerodigestive cervical traumas, the prognosis and outcome heavily depend on risk factors, particularly injuries to the larynx, trachea, major digestive tissues, cervical vertebrae, and vascular structures. With the increasing prevalence of trauma as a public health concern, there is a pressing need for epidemiological research and the implementation of preventative measures. The purpose of this research is to establish the profile of the predictable impact factors that determine the prognosis of patients with complex cervical trauma.

Stress and Burnout among Medical Specialists in Romania: A Comparative Study of Clinical and Surgical Physicians.

The MBI-Human Services Survey for Medical Personnel-MBI-HSS (MP) was used to measure burnout levels and investigate how they relate to dentists' intentions to change their profession. The sample included 69 Romanian dentists, 56 of whom were women and 13 of whom were men.

Hydroaminoalkylation for the Catalytic Addition of Amines to Alkenes or Alkynes: Diverse Mechanisms Enable Diverse Substrate Scope.

Hydroaminoalkylation is a powerful, atom-economic catalytic reaction for the reaction of amines with alkenes and alkynes. This C-H functionalization reaction allows for the atom-economic alkylation of amines using simple alkenes or alkynes as the alkylating agents. This transformation has significant potential for transformative approaches in the pharmaceutical, agrochemical, and fine chemical industries in the preparation of selectively substituted amines and -heterocycles and shows promise in materials science for the synthesis of functional and responsive aminated materials.

Flash Flood Vulnerability Mapping Based on FFPI Using GIS Spatial Analysis Case Study: Valea Rea Catchment Area, Romania.

The risk associated with extreme hydrological processes (flash floods, floods) is more present than ever, taking into account the global climatic changes, the expansion of inhabited areas and the changes emerging as a result of inadequate land management. Of all the hydrological risks, slope flash floods represent the processes that have the highest impact because of the high speed of their development and their place of origin, which makes them difficult to predict. This study is performed in an area susceptible to the emergence of slope flash floods, the Valea Rea catchment area, spatially located in Northwest Romania, and exposed to western circulation, which favours the development of such processes.

Burnout and Online Medical Education: Romanian Students in Lockdown and Their Residency Choices.

The primary aim of the study was to investigate the prevalence of burnout in Romanian medical students during the COVID-19 pandemic using the Maslach Burnout Inventory-General Survey for Students (MBI-GS(S)). The presence of burnout was assessed based on Exhaustion (EX), Cynicism (CY) and Professional Efficacy (PE) subscales. The secondary aim of the study was to identify the presence of intentional shift in medical specialty compared to their initial pursued choice within the population investigated.

Commodity Polymers to Functional Aminated Materials: Single-Step and Atom-Economic Synthesis by Hydroaminoalkylation.

Hydroaminoalkylation (HAA) is demonstrated to be a promising postpolymerization route to catalytically prepare amine-functionalized atactic polypropylene. Using a recently reported tantalum catalyst supported by a ,-chelating cyclic ureate ligand, vinyl-terminated polypropylene (VTPP) is transformed into both aryl and alkyl secondary amine-terminated polyolefins. Early transition-metal-catalyzed hydroaminoalkylation avoids protection/deprotection protocols typically required for secondary amine synthesis.

Applying a Complex Integrated Method for Mapping and Assessment of the Degraded Ecosystem Hotspots from Romania.

To meet the global challenges of climate change and human activity pressure on biodiversity conservation, it has become vital to map such pressure hotspots. Large areas, such as nation-wide regions, are difficult to map from the point of view of the resources needed for such mapping (human resources, hard and soft resources). European biodiversity policies have focused on restoring degraded ecosystems by at least 10% by 2020, and new policies aim to restore up to 30% of degraded ecosystems by 2030.

Cyclic Ureate Tantalum Catalyst for Preferential Hydroaminoalkylation with Aliphatic Amines: Mechanistic Insights into Substrate Controlled Reactivity.

The efficient and catalytic amination of unactivated alkenes with simple secondary alkyl amines is preferentially achieved. A sterically accessible, ,-chelated cyclic ureate tantalum catalyst was prepared and characterized by X-ray crystallography. This optimized catalyst can be used for the hydroaminoalkylation of 1-octene with a variety of aryl and alkyl amines, but notably enhanced catalytic activity can be realized with challenging -alkyl secondary amine substrates.

Feasibility Assessments Using Unmanned Aerial Vehicle Technology in Heritage Buildings: Rehabilitation-Restoration, Spatial Analysis and Tourism Potential Analysis.

The Transylvanian region of Romania is a place of rich history since ancient times, where the original natural environment around architectural heritage sites or buildings has not been severely altered by urban development. Unfortunately, many such places are left by the authorities to degrade or totally collapse for lack of funds, vision or initiatives. The current paper addresses the potential of Unmanned Aerial Vehicles (UAVs) in the assessment of a viable and feasible prospect of restoration on a 19th century mansion that belonged to a nobiliary family.

Comparing terrestrial laser scanning and unmanned aerial vehicle structure from motion to assess top of canopy structure in tropical forests.

Terrestrial laser scanning (TLS) and unmanned aerial vehicles (UAVs) equipped with digital cameras have attracted much attention from the forestry community as potential tools for forest inventories and forest monitoring. This research fills a knowledge gap about the viability and dissimilarities of using these technologies for measuring the top of canopy structure in tropical forests. In an empirical study with data acquired in a Guyanese tropical forest, we assessed the differences between top of canopy models (TCMs) derived from TLS measurements and from UAV imagery, processed using structure from motion.

Catalytic and Atom-Economic Csp3 -Csp3 Bond Formation: Alkyl Tantalum Ureates for Hydroaminoalkylation.

Atom-economic and regioselective Csp3 -Csp3 bond formation has been achieved by rapid C-H alkylation of unprotected secondary arylamines with unactivated alkenes. The combination of Ta(CH SiMe ) Cl , and a ureate N,O-chelating-ligand salt gives catalytic systems prepared in situ that can realize high yields of β-alkylated aniline derivatives from either terminal or internal alkene substrates. These new catalyst systems realize C-H alkylation in as little as one hour and for the first time a 1:1 stoichiometry of alkene and amine substrates results in high yielding syntheses of isolated amine products by simple filtration and concentration.

Tethered cationic alkaline earth - olefin complexes.

The aminofluoroalcohol N,N,N-(CH[double bond, length as m-dash]CHCHCH-),(CHOCHCH-),(HOC(CF)CH-)N ({RO}H) possessing both a methoxy and an olefin dangling side arms enables the preparation of the heteroleptic charge neutral alkaline earth complexes [{μ-RO}AeN(SiMeH)] (Ae = Ca, 1; Sr, 2). These O-bridged dinuclear complexes were characterised by NMR spectroscopy and X-ray diffraction crystallography. XRD analysis of 1 and 2 showed that both complexes are stabilised by intramolecular AeF-C and β-agostic AeH-Si secondary interactions, and that the olefin does not bind to the alkaline earths while the methoxy side-arm does.

All complexes are monomeric, with 3-coordinate metal centres.

The compositional characterisation of Romanian grape seed oils using spectroscopic methods.

In the present study, we developed a method for the grape seed oil compositional characterisation using (1)H NMR spectroscopy directly applied on oils without sample derivatisation (as triglycerides). Using (1)H NMR spectroscopy data and systems of chemometric equations, we established the composition of grape seed oils on four classes of fatty acids. Spectral information from (1)H NMR and FT-IR spectroscopy was used to make the differences between grape seed oils and genuine common oils.

Alkali aminoether-phenolate complexes: synthesis, structural characterization and evidence for an activated monomer ROP mechanism.

Several monometallic {LO(i)}M complexes of lithium (M = Li; i = 1 (1), 2 (2), 3 (3)) or potassium (M = K, i = 3 (4)) and the heteroleptic bimetallic lithium complex {LO(3)}Li·LiN(SiMe2H)2 (5), all supported by monoanionic aminoether-phenolate {LO(i)}(-) (i = 1-3) ligands, have been synthesized and structurally characterized. A large range of coordination motifs is represented in the solid state, depending on the chelating ability of the ligand, the size of the metal and the number of metallic centres found in the complex. Pulse-gradient spin-echo NMR showed that 1-4 are monomeric in solution, irrespective of their (mono- or di)nuclearity in the solid-state.

Synthesis of chromeno[3,4-b]indoles as Lamellarin D analogues: a novel DYRK1A inhibitor class.

A library of substituted chromeno[3,4-b]indoles was developed as Lamellarin isosters. Synthesis was achieved from indoles after a four-step pathway sequence involving C-3 iodination, a Suzuki cross-coupling reaction, and a one pot deprotection/lactonisation step. Twenty final compounds were tested in order to determine their activity against topoisomerase I and kinases, the two major biological activities of Lamellarins.
