Electrospun Polymeric Fiber Systems Inoculated with Cyanoacrylate Tissue Adhesive: A Novel Hemostatic Alternative during Open Surgery.

Natural-based and synthetic tissue adhesives have attracted extensive attention in the last two decades for their ability to stabilize uncontrolled bleeding instances. However; these materials present several drawbacks during use that scientists have tried to minimize in order to optimize their usage. This study comprises the development of a novel wound dressing, combining the excellent properties of polylactic acid (PLA) non-woven textile, as substrate, obtained through electrospinning, and a cyanoacrylate-based (CA) tissue adhesive, for rapid hemostatic action.

Ultrastructure of the Bovine Testis in Cattle (): New View.

The purpose of this study was to analyze the ultrastructure of the testes of sexually immature calves and reproductive bulls of the Polish Holstein-Friesian Black-and-White breed. Utilizing TEM, this study identified three distinct stages of seminiferous tubule development in calves, characterized by varying shapes, distributions, and arrangements of individual cells. In immature animals, early developing spermatocytes, prespermatogonia, and pre-Sertoli cells were observed within the seminiferous tubules.

Polydopamine conjugated SiO nanoparticles as potential drug carriers for melanoma treatment.

Silica nanoparticles (SiO) are increasingly investigated for biomedical applications. This study aimed to analyze the potential use of a SiO nanoparticles coated with biocompatible polydopamine (SiO@PDA) as a potential chemotherapeutic drug carrier. SiO morphology and PDA adhesion was analyzed by dynamic light scattering, electron microscopy and nuclear magnetic resonance.

The Morphological and Anatomical Traits of the Leaf in Representative Species Observed on Indoor- and Outdoor-Grown Plants.

Morphological and anatomical traits of the leaf were examined using microscopy techniques. Outdoor and plants and greenhouse cultivated and var. plants had interspecific variations.

Applications of superparamagnetic iron oxide nanoparticles in drug and therapeutic delivery, and biotechnological advancements.

Superparamagnetic iron oxide nanoparticles (SPIONs) have unique properties with regard to biological and medical applications. SPIONs have been used in clinical settings although their safety of use remains unclear due to the great differences in their structure and in intra- and inter-patient absorption and response. This review addresses potential applications of SPIONs in vitro (formulations), ex vivo (in biological cells and tissues) and in vivo (preclinical animal models), as well as potential biomedical applications in the context of drug targeting, disease treatment and therapeutic efficacy, and safety studies.
