Biochemical Characterization of Coriander Cakes Obtained by Extrusion
No full textThis study was designed to examine the effect of operating conditions such as nozzle diameter on fatty acid, sterol, and tocol composition of coriander cakes. Eight fatty acids were identified, with petroselinic acid accounting for 75–77% of the total fatty acids, followed by linoleic, oleic, and palmitic acids, accounting for 12-13%, 5%, and 3%, respectively, of the total fatty acids. β-Sitosterol was the major sterol in all oils with 33–35% of total sterols. The next major sterols in all oils were stigmasterol (24% of total sterols) and Δ7-stigmasterol (15% of total sterols). Coriander cake contained higher amounts of total tocotrienol where γ-tocotrienol was the main compound
Migrating from traditional grid to smart grid in smart cities promoted in developing country
No full textSmart Grid is a term that encompasses the economic benefits of an intelligent and advanced power grid to reach
changing responsibilities related directly to sustainability and energy efficiency. Considering the shortfall of
alternative fuels in developed regions, the new smart grids, in order to have access to their environmental hazard,
show that the average non-renewable and renewable energy sources can be integrated to reduce environmental
disasters to improve production costs significantly. In order to provide reliable, secured, and cost-effective power
grid functions, infrastructures can quickly and effectively co-ordinate power-sharing between several renewable
energy sources freely accessible and economically demand costs. This article reviews the conceptual model,
goals, architecture, potential benefits, and power grid issues with a complete and accurate understanding of the
different defenders and people involved in the worldwide region scenario. The article examined energy and
transmission issues, including smart grids and grid barriers, comprehensively

No full textLower paraoxonase 1 activity in Tunisian bipolar I patients
No full textAbstract Background The purpose of this study was to investigate the variations of paraoxonase activity and lipid profile in bipolar I patients, and the association of this activity with the sociodemographic, clinical and therapeutic characteristics of this population. Patients and methods Our study included 66 patients with bipolar I disorder and 64 controls aged 37.9 ± 12.6 and 36.3 ± 18.2 years, respectively. Paraoxonase activity was determined by kinetic methods; high-density lipoprotein cholesterol (c-HDL), low-density lipoprotein cholesterol (c-LDL), triglycerides and total cholesterol were determined by enzymatic methods; apolipoprotein (Apo)A1, ApoB and lipoprotein (a) (Lp(a)) were determined by immunoturbidimetry using Konelab 30 equipment (Thermo Scientific). Results Compared with controls, patients had a significantly lower paraoxonase activity and ApoA1 level, and significantly higher total cholesterol, c-LDL and Lp(a) level and ApoB/ApoA1 ratio. Furthermore, paraoxonase activity was significantly correlated with c-HDL values (r = 0.5612; P Conclusions Bipolar patients had a significant decrease in paraoxonase activity and perturbations in their lipid profile that contribute to increased risk of cardiovascular diseases. Decrease in this activity was significantly associated with treatment with lithium but not with sociodemographic and clinical characteristics. Therefore, such patients require specific care, particularly with regard to their lipid profile.</p

No full textChromosome number and genome size in Atriplex mollis from southern Tunisia and Atriplex lanfrancoi from Malta (Amaranthaceae)
No full textArtículo de 8 páginas que incorpora como material gráfico mapas de localización geográfica, tablas e imágenes de microscopio con cromosomas evidenciados.In this work, we investigated the chromosome number and genome size of two Mediterranean Amaranthaceae species, namely Atriplex mollis from southern Tunisia and A. lanfrancoi (formerly Cremnophyton lanfrancoi) from Malta. The two species were found to be diploid (2n=18) for all examined populations. This result is different from that previously reported for Cremnophyton lanfrancoi Brullo and Pavone (2n=20). Genome size showed that both species have a close mean amount with 2C=3.41 and 3.51 pg, respectively. Two groups were distinguished with regard to genome size (P<0.01). It should, however, be noted that the majority of populations, with the exception of those from Djerba and Chbika, may be intermediate between the two basic groups. Moreover, the difference does not appear to depend on geographical distribution and environmental aspects. It would rather depend on chromosome rearrangements. The morphological similarities, the monophyly of Atriplex including A. lanfrancoi, previously ranked in genus Cremnophyton, sharing the same chromosome number and the same genome size, support the placement of Cremnophyton within the genus Atriplex.This study was supported by the ERANETMED2-72-303 PACTORES project financed by the Ministry of Higher Education and Scientific Research of Tunisia and University of Malta (Argotti Botanic Gardens) and by projects 2017SGR1116 (Catalan government) and CGL2017-84297-R (Spanish government).Abstract

National Tunisian Multicenter Prospective Study on Cardiac Implantable Electronic Devices (Tunisian NATURE-CIED study): One-year complications and predictive factors
No full textBackground: The prevalence of cardiac implantable electronic devices (CIEDs) in Tunisia is rising because of increased life expectancy and broader indications. This has led to a higher incidence of complications related to vascular access, device pockets, leads, and patient characteristics. Objective: We aimed to evaluate the prevalence, types, and predictors of complications occurring within the first year after CIED implantation and to profile the demographic and epidemiologic characteristics of CIED recipients in Tunisia. Methods: The National Tunisian Multicenter Prospective Study on Cardiac Implantable Electronic Devices is a nationwide, prospective study. We enrolled consecutive patients, from January 2021 to February 2022, undergoing de novo implantation of pacemakers, implantable cardioverter defibrillators, cardiac resynchronization therapy devices, generator replacements, and upgrading procedures. Patients attended 4 follow-up visits within the first year. Results: We enrolled 1500 patients with a mean age of 70.1 ± 15.2 years. Most (86.5%) received conventional pacemakers. The overall complication rate was 8.6%, with 129 complications in 80 patients. No significant associations were found between age or gender and complication rates. However, overweight and obesity were independent predictors of overall complications. Procedures performed in private health care settings were associated with a 56.2% reduction in complication rates. Generator replacements were linked to a 64.2% decrease in complication rates. Conversely, urgent or out-of-hours procedures increased the risk of complications by 62.7%. Procedures performed by non-electrophysiologist implanters were associated with an 89.5% increase in overall complication rates. Conclusion: Complications were more prevalent with cardiac resynchronization therapy devices. Identifying specific procedural predictors may pinpoint patients at higher risk, affecting personalized treatments and CIED implantation strategies
Cardiovascular disease in North African women: insights from the Middle East African Women CardioVascular Disease (MEA-WCVD) registry
No full textCardiovascular disease (CVD) is a major health burden worldwide, yet gender-specific data from the Middle East and North Africa (MENA) region remain scarce. The Middle East African Registry of Women with Cardiovascular Disease enrolled adult patients with coronary heart disease (CHD), heart failure (HF), atrial fibrillation (AF), or valvular heart disease (VHD) across Tunisia between May and July 2023. Of 15,366 patients, 37.6% were women. Compared with men, women were older, had lower socioeconomic status, and presented with more obesity, hypertension, diabetes, dyslipidemia, and sedentary lifestyle but smoked less. CHD was less frequent in women, while AF and VHD were more prevalent. Women underwent fewer coronary angiographies and percutaneous interventions, experienced longer delays, and received fewer guideline-based therapies, including dual antiplatelet agents and high-intensity statins. Among HF patients, women more often had preserved ejection fraction and higher hospitalization rates. These results highlight persistent gender inequities in CVD care in Tunisia
