Prostate cancer progression: a scoping review, pharmacoeconomic assessment, and...
Dinis de Sousa, Rute; Zagalo, Daniela Mariana; Gouveia, Miguel; Gomes, Luís; Santos Dias, José; Mansinho, André; Santos, Susana; Mariano, JoséAIMS/BACKGROUND: Prostate cancer is the most common malignancy in men and a leading cause of cancer-related death. Progression from non-metastatic castration-resistant prostate cancer (nmCRPC) to metastatic CRPC (mCRPC) significantly worsens health-related quality of life (HRQoL), increases mortality, and raises healthcare costs. This study assessed the impact of avoiding or delaying progression to mCRPC on HRQ...
MnCr2O4: A suitable material with significant optical response for optoelectron...
Hajji, Ala Ben Abderrazak; Wali, Mouna; Dhahri, Radhia; Kammoun, Souha; Dhahri, Essebti; Mariano, José; Jemmali, MosbahIn current high-tech electronics, a power-efficient and compact light source has an essential role to play in the development of non-destructive and non-invasive detection applications as well as for advancing of technological innovation. In this order, an innovative investigation has been taken into consideration in this paper to characterize the optoelectronic behaviour of MnCr2O4 spinel chromite compound bas...
Effect of biochar binding on dielectric properties of color catcher sheets
Kovalchuk, O. V.; Prochazkova, J.; Kovalchuk, T. M.; Volokh, L. V.; Oleinikova, I. V.; Mariano, José; Safarik, I.; Kopansk, P.The dielectric properties in the frequency range of 102 to 106 Hz and at the temperatures of 30 to 60 °C of 0.4 mm thick color catcher sheets (nonwoven textile with ion exchange properties) both in the native state and with bound biochar were investigated using the oscilloscope method. The sample dimensions were 1×1 cm. To assess the influence of the sample thickness, samples with several (maximum 4) layers wer...
A comprehensive study of the structural, magnetic and optoelectronic behavior o...
Hajji, Ala Ben Abderrazak; Wali, Mouna; Dhahri, Radhia; Dhahri, Essebti; Mariano, José; Jemmali, MosbahChromium-based spinel oxides have recently gained popularity in commercialisation field owing to its suitability in optoelectronic applications. Pure phase Ni0.6Mn0.4Cr2O4 spinel chromite nanopowder with a cubic structure and (Fd3m) space group was successfully synthesised via the sol gel route. Magnetic and optical characterisation were performed by the vibrating sample magnetometry (VSM) and UV–Visible spectr...
MnCr2O4: a promising material with suitable magnetic response for spintronic an...
Wali, Mouna; Hajji, Ala Ben Abderrazak; Dhahri, Radhia; Dhahri, Essebti; Mariano, José; Morales, Marco A.; Silva, Rodolfo B. daOver the last few years, a new magnetic nanoparticles system has been elaborated in order to enhance the magnetic feature of spintronic and ultra-high-density recording devices with respect to promoting the anisotropic behaviour and ensuring the magnetic ordering stability. The smart MnCr2O4 chromite compound is becoming more popular these days thanks to its promising potential to create an extra source of anis...
Effect of modification of nonwoven textiles with biochar and multi-walled carbo...
Kovalchuk, O. V.; Prochazkova, J.; Kolanowska, A.; Mariano, José; Boncel, S.; Zolochevska, K.; Kovalchuk, T. M.; Kopčanský, P.; Safarik, I.Dielectric properties of native nonwoven textile as well as textile with bound biochar and multi-walled carbon nanotubes in the frequency range of 10 to 5·105 Hz and at the temperatures of 30 to 60 °C have been investigated. The capacity of native nonwoven textile has been shown to decrease with the temperature according to the Arrhenius law. The activation energy of the temperature dependence of the capacity h...
mef2ca and mef2cb Double mutant Zebrafish show altered craniofacial phenotype a...
Adrião, Andreia; Mariano, Sara; Mariano, José; Gavaia, Paulo; Cancela, M. Leonor; Vitorino, Marta; Conceição, NatérciaThe transcription factor MEF2C is crucial in neuronal, cardiac, bone and cartilage molecular processes, as well as for craniofacial development. MEF2C was associated with the human disease MRD20, whose patients show abnormal neuronal and craniofacial development. Zebrafish <i>mef2ca</i>;<i>mef2cb</i> double mutants were analysed for abnormalities in craniofacial and behaviour development through phenotypic anal...
The effect of transition metal substitution on the structural, elastic, optical...
El Heda, Issa; Massoudi, Jalel; Dhahri, Radhia; Dhahri, Essebti; Bahri, Fathi; Omari, L.H.; Mariano, JoséSpinel nanoparticles M0.5Fe2.5O4 (M = Co,Mg) were elaborated by the auto-combustion method using glycine as a fuel. X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectroscopy have been invested to investigate the structural and morphological properties of these compounds. The optical study reveals that these samples exhibit a strong absorption in the visible range. They possess int...
Zolpidem and Disorders of Consciousness: The Path to a New Therapy
Mariano, José; Gomes, Catarina; Figueiredo, Isabel Vitória; Cabral, Ana CristinaZolpidem is a benzodiazepine-like agent. It is a positive allosteric modulator of GABA-A receptors, altering their conformational structure and increasing the binding affinity of the neurotransmitter GABA to its orthosteric binding site. Its only approved indication is insomnia, due to its central depressant effect. Since the end of the 90's, there have been numerous studies regarding its use in patients with b...
Theoretical study of magnetic and magnetocaloric properties and MCE modeling by...
Nasri, M.; Henchiri, C.; Dhahri, R.; Dhahri, E.; Omari, L.H.; Mariano, JoséIn this research paper, we are basically interested in the theoretical investigation of magnetic and magnetocaloric properties of CoFeCuO4 spinel ferrite. Our sample was prepared using the sol-gel method. The XRD analysis confirmed the cubic spinel structure with the Fd (3) over barm space group exhibited by our compound. Furthermore, the positive slope detected in the Arrott plots is indicative of the second-o...
