Background: Although the co-occurrence of psychotic experiences (PEs) and psychological distress symptoms is growingly recognized in several previous studies, there is still a lack of literature, which clearly outlines how these two psychopathological entities affect each other over time. This study is intended to add to the literature by examining: (a) the longitudinal, bidirectional associations between PEs and psychological distress in a sample of Tunisian adolescents, and (b) whether these associations are moderated by sex.

Methods: 510 adolescent students (mean age of 16.

Article Synopsis
  • - This study investigates the link between maternal fatty acid (FA) levels during pregnancy and the risk of neural tube defects (NTDs), assessing various nutrient levels like vitamin D, homocysteine, vitamin B, and folate in relation to the cases.
  • - Results show that women with NTD cases had higher levels of specific fatty acids (like heptadecanoic and arachidonic acid) and lower levels of omega-3 polyunsaturated fatty acids (n-3 PUFA) compared to controls.
  • - Additionally, maternal 25-hydroxyvitamin D (25(OH)D) was found to positively correlate with certain polyunsaturated fatty acids, while RBC folate levels were negatively correlated

Accurate skin diagnosis through end-user applications is important for early detection and cure of severe skin diseases. However, the low quality of dermoscopic images hampers this mission, especially with the presence of hair on these kinds of images. This paper introduces , a novel, self-supervised conditional diffusion model designed specifically for the automatic generation of hairless dermoscopic images to improve the quality of skin diagnosis applications.

The increasing salinity and alkalinity of soils pose a global challenge, particularly in arid regions such as Tunisia, where about 50% of lands are sensitive to soil salinization. Anthropogenic activities, including the use of treated wastewater (TWW) for irrigation, exacerbate these issues. Haloalkaliphilic bacteria, adapted to TWW conditions and exhibiting plant-growth promotion (PGP) and biocontrol traits, could offer solutions.

Background: Long-term deterioration in the mental health of healthcare workers (HCWs) has been reported during and after the COVID-19 pandemic. Determining the impact of COVID-19 incidence and mortality rates on the mental health of HCWs is essential to prepare for potential new pandemics. This study aimed to investigate the association of COVID-19 incidence and mortality rates with depressive symptoms over 2 years among HCWs in 20 countries during and after the COVID-19 pandemic.

An extensive number of publications have examined cross-education effects with adults, primarily investigating contralateral homologous (same) muscles. There are far fewer investigations on cross-education effects on contralateral heterologous (different) muscles and age (youth vs adult) and no studies investigating sex differences. Hence, the objective was to compare cross-education in female and male youth and young adults to contralateral homologous (chest press [CP], elbow flexors and extensors, handgrip isometric strength, and shot put) and heterologous (leg press, knee extension isometric strength, and countermovement jump) muscles.

In response to the rapidly evolving threat landscape in network security, this paper proposes an Evolutionary Machine Learning Algorithm designed for robust intrusion detection. We specifically address challenges such as adaptability to new threats and scalability across diverse network environments. Our approach is validated using two distinct datasets: BoT-IoT, reflecting a range of IoT-specific attacks, and UNSW-NB15, offering a broader context of network intrusion scenarios using GA based hybrid DT-SVM.

BMC Microbiol

September 2024

UMR BIPAR, Laboratoire de Santé Animale, ANSES, INRAE, Ecole Nationale Vétérinaire d'Alfort, Maisons-Alfort, 94700, France.

Article Synopsis
  • - This study builds on previous research about how antibiotics affect the tick microbiota, particularly the transmission of Babesia microti, by comparing antibiotic-treated (AT) and control-treated (CT) Haemaphysalis longicornis ticks to observe changes in their microbial community interactions.
  • - Results indicated that AT ticks had a more connected but less interactive microbial community, showing significant differences in network centrality measures, which reflect how different bacteria interact within the community.
  • - The findings highlight that certain bacteria like Coxiella and Acinetobacter play key roles in maintaining network stability, and the antibiotic treatment made these networks less robust, indicating a higher susceptibility to disturbances.
