“…Poly-vinyl-pyrrolidone (PVP)-coated AgNP (< 50 nm; 99.1% purity) were locally produced using a modified polyol process [ 25 26 ] by the chemistry department (FSB, Bizerte, Tunisia). As previously reported [ 27 ] TEM analysis (TECNAI G20, Ultra-Twin, FSB, Bizerte, Tunisia) for AgNP <50 nm demonstrated homogeneous spherical characteristics with an approximate size of 50 nm. Size distribution revealed median size of 41.6 ± 18.82 nm.…”

“…As previously reported, PDI has been found to promote matrix/cytoskeletal organization which could explain its expression modification found here. AgNPs-associated injury has previously been documented in mussel gill and digestive gland by [ 27 , 57 ]. Thus, PDI identification, in the current study, to be associated to procollagen-proline dioxygenase is not surprising.…”

“…NPs have unique physiochemical properties because of their size and large surface area-to-volume ratio, rendering them more reactive and thermodynamically unstable than bulk materials ( 5 , 6 ). Moreover, NPs are easily absorbed and readily interact with the human body when delivered through inhalation, penetration, and ingestion ( 7 , 8 ). However, issues regarding their toxicity and safety due to adverse biological effects have led to widespread concerns about the possible negative effects of NPs ( 9 , 10 ).…”

“…Cuando consideramos que el tejido gonadal de C. undatella muestra una infiltración de células eosinófilas con una prevalencia alta (intermedia y abundante) en todos los meses y fases de desarrollo gonádico, podemos descartar dos causas: presencia de alguna infección por parásitos (no se encontró evidencia de su presencia) o que se deba al proceso de recuperación natural de la gónada (se presentó en el desarrollo y la madurez con > 80% de prevalencia). Por lo tanto, se podría hipotetizar que, debido a que estos organismos están expuestos crónicamente a un ambiente contaminado por metales (Shumilin et al, 2013), estas células están relacionadas con la reacción celular a estrés abiótico, el cual resulta en un proceso de inflamación inmune innato (Bouallegui et al, 2017).…”

“…Distintos autores mencionan que después del transporte de hemocitos y células cafés, algunos tejidos se identifican como blancos de acumulación o desintoxicación de contaminantes en moluscos (Boscolo-Papo et al, 2014). Estas infiltraciones se presentan acompañadas de alteraciones morfológicas a nivel celular, como un decremento en el volumen de una célula o un órgano, así como una pérdida de grosor del epitelio o atrofia (Bouallegui et al, 2017). Esta pérdida de la arquitectura normal del tejido gonadal en C. undatella fue evidente con la reducción y desaparición del tejido conectivo.…”
