Impact of homologous overexpression of PR10a gene on improving salt stress tolerance in transgenic Solanum tuberosum.

Abiotic stresses severely affected crop productivity and considered to be a major yield limiting factor for crop plant. The tolerance to these stresses is a very complex phenomenon involving a wide array of molecular, biochemical and physiological changes in plant cells. Therefore, it is challenging to understand the molecular basis of abiotic stress tolerance to manipulate it for improving abiotic stress tolerance of major crops.

Towards Bronchoscopic Functional CFTR Assessment using a Short Circuit Current Measurement Probe.

The epithelial lining of luminal organs provides an immune barrier against external factors and regulates transport of nutrients, ions, and water into the body. Several conditions are associated with a breakdown or dysfunction of the epithelial lining. Short circuit current (I) measurement using a bulky, expensive, and hard to deploy system known as the Ussing chamber is the gold standard for evaluation of epithelial transport function but requires tissue excision.

assessment of topically applied silver nanoparticles on entire cornea: comprehensive FTIR study.

Silver nanoparticles (AgNPs) have gained attention in medicine for their potent antibacterial, antiviral, and anti-inflammatory properties. The use of silver nanoparticles in ophthalmic solutions raises concerns regarding potential toxicity of nanoparticles to ocular tissues, such as the cornea, conjunctiva, and retina, which necessitates further toxicity assessments aiding in the development of safer ophthalmic solutions. This study investigates the impact of AgNPs on corneal tissue using ophthalmic investigations, Fourier transform infrared (FTIR) spectroscopy, and chemometric analyses.

Drug resistance and genomic variations among Mycobacterium tuberculosis isolates from The Nile Delta, Egypt.

Tuberculosis is a global public health concern. Earlier reports suggested the emergence of high rates of drug resistant tuberculosis in Egypt. This study included 102 isolates of Mycobacterium tuberculosis collected from two reference laboratories in Cairo and Alexandria.

Digital workflow for graft harvest and positioning in deficient anterior mandibles versus conventional technique: Randomized controlled trial.

Background: The cortical shell technique is frequently associated with technical drawbacks, such as the lack of anatomical guidance during shell harvest and graft. This study aims to assess the horizontal bone gain and accuracy of a digitalized protocol that incorporates two interlocking patient-specific stackable guides (PSSGs) to control the shell harvest, positioning, and fixation.

Patients And Methods: Twenty patients with deficient anterior mandibles were randomly allocated; 10 patients received freehand symphyseal shell harvest and fixation (the control group), whereas the other 10 received fully guided harvest and graft (study group) using (PSSGs), the first aided an accurate shell harvest, whereas the second conveyed shell fixation.
