The Tunisian health care system is experiencing a significant period of change and needs reforms so as to adapt. The nursing profession, which is the main actor of this system, in terms of number and function, is barely known or utterly unknown. The present paper's authors, who are paramedical teachers, aim to shed light on the specificity of the nursing and the nursing profession based on data collecting, and rare articles and legislation texts. In four sections, the paper will discuss the following issues: the nursing population demography, providing several indicators, their training throughout the reforms period, their training which has been "hooked" to university studies, their job profile and career plan...

We report the key role of the capping agent in the detection of metal cations using tannic acid (TA) capped gold nanoparticles at both ensembles (using cyclic voltammetry) and with individual particles (using oxidative and reductive nanoimpacts). The results show that the capping agent complexes with Zn2+ and Hg2+ in a reversible and Langmuirian manner in both cases. The sensitivity of detection is determined by the amount of capping agent present on the nanoparticles with similar values seen for both oxidation and reduction reactions...

We report an unusual case of a frontal partially calcified pilocytic astrocytoma (PA) (WHO grade 1) in an 18-year-old woman who presented with acute, spontaneous intracerebral hemorrhage. Histopathology revealed the PA was mixed with psammoma bodies and areas of vascular proliferation responsible for a hypervascular pattern. The patient underwent a total gross resection. MRI showed no residual tumor at the 18-month follow-up and her neurological deficits improved after rehabilitation. Only 20 cases, including ours, of hemorrhagic presentation of PA in adults have been reported to date with enough radiological data...

Human epidermal growth factor receptor 2 (HER2)-targeted vaccines are under development, but have so far demonstrated only modest clinical efficacy. Additionally, there has been a lack of adequate safety assessment in large-scale prospective clinical trials. Therefore, we performed a meta-analysis of available clinical trial data to summarize the toxicity profiles of these treatments. Literature search was conducted in February 2018. The trials analyzed had at least one study arm consisting of HER2 vaccine monotherapy...

Thorough studies of previous analytical stress data of tetrabenazine, a dopamine depleting agent, showed a potential susceptibility to acidic conditions. Hence, the behavior of tetrabenazine acidic solutions was studied by LC-MS and NMR spectroscopy. Reverse-phase LC-MS analysis of tetrabenazine acidic aqueous solutions consistently showed a main lipophilic impurity in a proportion of 15 to 20%. NMR spectroscopy studies did not allow to completely ascertain its structure. However, we hypothesize an interconversion of trans -tetrabenazine with its unstable cis isomer via an open isoquinolinium intermediate...

Tumour-specific, immuno-based therapeutic interventions can be considered as safe and effective approaches for cancer therapy. Exploitation of nano-vaccinology to intensify the cancer vaccine potency may overcome the need for administration of high vaccine doses or additional adjuvants and therefore could be a more efficient approach. Carbon nanotube (CNT) can be described as carbon sheet(s) rolled up into a cylinder that is nanometers wide and nanometers to micrometers long. Stemming from the observed capacities of CNTs to enter various types of cells via diversified mechanisms utilising energy-dependent and/or passive routes of cell uptake, the use of CNTs for the delivery of therapeutic agents has drawn increasing interests over the last decade...

Benzimidazole is an interesting scaffold constituting a main core in many anticancer agents against variable cell lines as Carbendazim (I) and Nocodazole (II). Accordingly, eighteen compounds of 2-((1H-benzoimidazol-2-yl)thio)-1-(aryl/heteroaryl)ethan-1-ones, in their sulfate salt and free forms, were designed and investigated as anticancer agents. In vitro preliminary screening of selected compounds by the National Cancer Institute (NCI) on a panel of 60 cell lines revealed renal cancer cell line (A498) as the most vulnerable cell line; accordingly, IC50 values against A498 cell line were determined for compounds with the best results...

Fabry's disease (FD) is the second most commonly occurring lysosomal storage disorders (LSDs). The mutations in α-galactosidase A (GLA) protein were widely found to be causative for the Fabry's disease. These mutations result in alternate splicing methods that affect the stability and function of the protein. The mutations near the active site of the protein results in protein misfolding. In this study, we have retrieved the missense mutation data from the three public databases (NCBI, UniProt, and HGMD). We used multiple in silico tools to predict the pathogenicity and stability of these mutations...

Gaucher's disease (GD) is the most commonly known lysosomal disorder that occurs due to mutations in the β-glucocerebrosidase (GBA) protein. Our previous findings (Thirumal Kumar, Eldous, Mahgoub, George Priya Doss, Zayed, 2018) and other reports concluded that the mutations N370S and L444P are the most significant mutations that could cause disruptions in protein stability and structure. These disruptions lead to protein misfolding and result in a diseased condition. Enzyme Replacement Therapy (ERT) and Pharmacological chaperone therapy (PCT) are currently used to treat GD caused by mutations in the GBA protein...
