Lack of NLRP3 inflammasome activation reduces age-dependent sarcopenia and mitochondrial dysfunction, favoring the prophylactic effect of melatonin
To investigate the role of NLRP3 inflammasome in muscular aging, we evaluated here the morphological and functional markers of sarcopenia in the NLRP3-knockout mice, as well as the beneficial effect of melatonin supplementation. The gastrocnemius muscles of young (3 months), early-aged (12 months), and old-aged (24 months) NLRP3-knockout female mice were examined. Moreover, locomotor activity and apoptosis were assessed. The ... Read more

Protective action of salicylic acid against bean yellow mosaic virus infection in Vicia faba leaves
In this study, morphological, ultrastructural and physiological modifications of faba bean (_Vicia faba_ cv Giza 461) leaves in response to bean yellow mosaic virus (BYMV) infection and salicylic acid (SA) treatments were examined. Under BYMV stress, leaves showed symptoms including severe mosaic, mottling, crinkling, size reduction and deformations. Three weeks after virus inoculation, photosynthetic rate, pigment contents and transpiration rate ... Read more

Detection and partial characterization of a putative closterovirus affecting Ficus carica: molecular, ultrastructural and physiological aspects of infected leaves
_Fig mosaic disease_ (FMD) was systemically transmitted to susceptible fig plants by grafting and led to development of symptoms including a wide array of discoloration, green blisters, mottling, crinkling and deformation of leaves and fruits. A sensitive assay for the detection of FMV using specific enzyme-linked immune sorbent assay and reverse transcription-polymerase chain reaction was developed. A double-stranded RNA ca. ...

Efficacy of Tamoxifen and L- carnitine on Sperm Ultrastructure and Seminal Oxidative Stress in patients with idiopathic Oligoasthenoteratozoospermia.
Idiopathic oligoathenoteratozoospermia (iOAT) is a common finding in the evaluation of male infertility. Oxidative stress (OS) may underlie its pathology. Tamoxifen and L-carnitine are used to treat idiopathic male infertility. The aim of this work was to detect the efficacy of tamoxifen and L-carnitine on sperm parameters, sperm ultrastructure and seminal OS in iOAT patients. Sixty patients were recruited for ...
