Exosomes, which are considered nanoscale extracellular vesicles (EVs), are secreted by various cell types and widely distributed in different biological fluids. They consist of multifarious bioactive molecules and use systematic circulation for their transfer to adjoining cells. This phenomenon enables exosomes to take part in intercellular and intracellular communications.

Department of Pathology, University of Sousse Faculty of Medicine of Sousse, Farhat Hached Teaching Hospital, Sousse, Tunisia.

Tuberculosis (TB) of the rib is an uncommon manifestation of extrapulmonary TB that can pose significant diagnostic challenges, especially when presenting as a breast mass. We report the case of a 74-year-old woman who presented with a left breast lump, initially suspected to be a plasmacytoma due to its imaging characteristics and clinical history. The mass was surgically excised, and histopathological analysis revealed granulomatous inflammation with caseous necrosis, suggesting TB.

Theoretical assessment of the adsorption mechanism of carvone enantiomers on cow btOR1A1: New microscopic interpretations.

Int J Biol Macromol

December 2024

Laboratory of Quantum and Statistical Physics LR 18 ES 18, Faculty of Sciences of Monastir, Environnement Street, 5019 Monastir, Tunisia.

In this study, the olfactory threshold concentration was introduced in the statistical physics approach to provide fruitful and deep discussions. Indeed, a modified mono-layer mono-energy model established using statistical physics theory was successfully used to theoretically study the adsorption involved in the olfactory response of (R)-(-)-carvone and (S)-(+)-carvone key food odorants (KFOs) on cow (Bos taurus) olfactory receptor btOR1A1 through the analysis of the different model physicochemical parameters. Thus, stereographic results indicated that the two carvone enantiomers were non-parallelly docked on btOR1A1 binding sites during the adsorption process since the different values of n were superior to 1.

Cervical cancer is one of the deadly diseases that affects women, which requires periodic examinations to identify and treat any cancerous tumors at a preliminary stage. The most prevalent examination tool for cervical cancer prompt identification is the cervical smear (Pap smear) testing; however, due to human negligence, this examination method has an elevated probability of negative findings. Cervical cancer classification using machine learning (ML) and deep learning (DL) has been extensively studied to enhance the conventional diagnostic process.

This paper presented the preparation, characterization, and adsorption properties of Brazil nut shell activated carbon for catechol removal from aqueous solutions. The equilibrium adsorption of catechol molecules on this activated was experimentally quantified at pH 6 and temperatures ranging from 25 to 55 °C, and at 25 °C and pH ranging from 6 to 10. These results were utilized to elucidate the role of surface functionalities through statistical physics calculations.

Article Synopsis
  • The study shows that electrical charges from redox couples are not needed to detect electroactive proteins using a specialized electrochemical sensor.
  • Researchers created a polydopamine-based biosensor to detect bovine serum albumin, finding better results without redox probes in phosphate-buffered solutions.
  • The findings suggest that adding redox probes can interfere with protein interactions, and the method was verified by detecting other proteins like human serum albumin and immunoglobulin G, indicating a new approach for quantifying electroactive proteins.
