Introduction: HLA matching is critical for successful kidney transplantation. This study aimed to investigate the impact of eplet mismatches and Predicted Indirectly Recognizable HLA Epitopes (PIRCHE-II) scores on the development of de novo donor-specific antibodies (dnDSA) and graft survival in a Tunisian cohort, characterized by a high prevalence of living donors and significant genetic diversity in HLA profiles.
Methods: This retrospective study included 112 adult kidney transplant recipients who underwent transplantation between 2012 and 2018.
A hallmark feature of pancreatic ductal adenocarcinoma (PDAC) is massive intratumoral fibrosis, designated as desmoplasia. Desmoplasia is characterized by the expansion of cancer-associated fibroblasts (CAFs) and a massive increase in extracellular matrix (ECM). During fibrogenesis, distinct genes become reactivated specifically in fibroblasts, e.

As the volume and scale of structures and the impact of their failure continue to grow, there is a dire need for SHM techniques that are scalable, inexpensive, can operate passively without human intervention, and are customized for each mechanical structure without the need for complex baseline models. We present a novel "deploy-and-forget" approach for automated detection and localization of damage in structures.

Pulmonary TB is the most common form of the disease, but TB bacilli can spread to other organs including lymph nodes, and the oral cavity especially the tongue with very unusual features. Oral lesions, although rare, are very important for early diagnosis and interception of primary TB.

These emerging devices offer unique advantages such as non-volatile memory, low power consumption, and a high integration density. Their scalability and compatibility with existing fabrication processes make them an attractive option for industry adoption, paving the way for faster and more efficient architecture design.

Hyoid bone fracture unrelated to strangulation is a rare occurrence characterized by a subtle presentation. However, it may manifest as a fatal respiratory distress due to airway obstruction. We present 2 cases of hyoid bone fractures that occurred following a traffic accident in 2 male patients.

Given the unique anatomical characteristics of the infratentorial region, mainly its small size, surgical intervention is commonly undertaken to alleviate the pressure on the posterior fossa components. Consequently, there is ongoing debate surrounding the optimal surgical approaches.
View Article and Find Full Text PDFPancreatic ductal adenocarcinoma (PDAC) is associated with a vast stromal reaction that arises mainly from cancer-associated fibroblasts (CAFs) and promotes both immune escape and tumor growth. Here, we used a mouse model with deletion of the activin A receptor ALK4 in the context of the mutation, which strongly drives collagen deposition that leads to tissue stiffness. By ligand-receptor analysis of single-cell RNA-sequencing data, we identified that, in stiff conditions, neoplastic ductal cells instructed CAFs through sustained platelet-derived growth factor (PDGF) signaling.
View Article and Find Full Text PDFFibromatosis or desmoid tumors are rare benign fibroblastic lesions that are rarely present in the head and neck regions. When they do occur in these regions, however, they tend to be aggressive toward the surrounding tissue and be associated with heavy morbidity and mortality. We report the case of a 26-year-old Tunisian female who presented with acute obstructive dyspnea and a 3-week history of cervical swelling.

Methods: Retrospective cross-sectional study comparing between NV-PDS and NNV-PDS. All patients underwent multimodal imaging including infracyanine green angiography (IFCGA) and swept source optical coherence tomography (OCT) and angiography (OCT-A).
Introduction And Importance: Spinal meningiomas are typically intradural lesions. Some may infiltrate the dura mater, thus exhibit direct extradural extension. Pure spinal epidural meningiomas are very rare.

However, the reuse of this water requires secondary and tertiary treatment processes to reduce or eliminate a load of dissolved organic matter and various emerging contaminants. Microalgae have shown hitherto high potential applications of wastewater bioremediation thanks to their ecological plasticity and ability to remediate several pollutants and exhaust gases from industrial processes.

First, we seek to understand the characteristics of the multimorbid population that needs hospital care by using all diagnoses information (ICD-10 codes) and two aggregated multimorbidity and frailty scores. Second, we use machine learning prediction models on these multimorbid patients characteristics to predict rehospitalization within 30 and 365 days and their length of stay.

These measurements are composed of acoustic emission signals and welding parameters. Acoustic emission signals were captured by three different piezoelectric sensors, which are connected to a Vallen AMSY5 system through preamplifiers.

To our knowledge, few epidemiological studies are available on vitiligo induction factors and particularly on the role of exposure to chemicals in the onset of the disease has been found. Therefore, there is need to investigate the relationship between vitiligo and chemical exposures in order to understand this mysterious disease.

Mindfulness, defined as the awareness that arises by intentionally paying attention in the present moment and in a non-judgmental way, seems to be a moderator in the causal association between life stressors and well-being.
Aims: The aim of the present study was to test the model of relationships between self-reported mindfulness, perceived stress, well-being index and life satisfaction in a sample of Tunisian HCPs.
