Aim: Aim of this study was to assess the quality of the corrosion specimens obtained during autopsies of human body for scanning electron microscopy procedures.
Materials And Method: Ninety seven uteri were obtained upon autopsy of women aged 25-56 years, deceased due to causes not related to disorders of the reproductive system. Fourty three of them contained large subserosal uterine leiomyomata. twenty uteri were injected with acrylic emulsion Liquitex R via the arteries or veins. Five of these uteri were next dissected and cut into slides on a microtom. the remaining uteri were injected with 60-80 ml of mercox CL-2r resin, next macerated and studied under scanning electron microscope (JEOL SEM 35-CF scanning electron microscope at 20-25 kV).
Results: Best human specimens were obtained from the autopsies carried out possibly early after the deceased, young aged (between 25 and 45) and died because of multitrauma not associated with the pelvic injury.
Conclusions: Specimens obtained from autopsies can be used for scanning electron microscopy however under several conditions, specially the time between death and undertaking the injection procedures and the age of the individual, because of the process of artherosclerosis.

RNA pesticides have emerged as a promising alternative to conventional chemical pesticides due to their high specificity and minimal environmental impact. However, the instability of RNA molecules in the environment and the challenges associated with their effective delivery to target pests limit their broader application. This study addresses these challenges by developing a dual delivery system using chitosan (CS) and Metal-Organic Frameworks (MOFs) to enhance the delivery and efficacy of double-stranded RNA (dsRNA) and cycloxaprid against , a vector of citrus greening disease.

The stomatal phenotype is a crucial microscopic characteristic of the leaf surface, and modulating the stomata of maize leaves can enhance photosynthetic carbon assimilation and water use efficiency, thereby playing a vital role in maize yield formation. The evolving imaging and image processing technologies offer effective tools for precise analysis of stomatal phenotypes. This study employed Jingnongke 728 and its parental inbred to capture stomatal images from various leaf positions and abaxial surfaces during key reproductive stages using rapid scanning electron microscopy.

Although LFH is associated with increased fibrosis in the dorsal layer, comprehensive research exploring the characteristics of the ECM and its mechanical properties in both regions is limited. Furthermore, the distribution of fibrosis-associated myofibroblasts within LFH remains poorly understood.

Laser surface alloying of Fe, Si, and C on aluminium is demonstrated using a Q-switched Nd:YAG laser as the source of energy. The fundamental wavelength of the laser beam was 1064 nm with an output energy of 100 mJ and a pulse duration of 10 ns. The exposure was conducted in repetitive mode with a frequency rate of 1 Hz.

Although membrane technology is widely used in different gas separation applications, membrane manufacturers need to reduce the environmental impact during the membrane fabrication process within the framework of the circular economy by replacing toxic solvents, oil-based polymers, and such by more sustainable alternatives. These include environmentally friendly materials, such as biopolymers, green solvents, and surfactant free porous fillers. This work promotes the use of environmentally sustainable and low toxic alternatives, introducing the novel application of cellulose acetate (CA) as a biopolymer in combination with dimethyl carbonate (DMC) as a greener solvent and different inorganic fillers (Zeolite-A, ETS-10, AM-4 and ZIF-8) prepared without the use of toxic solvents or reactants.
