Microplastic pollution is believed to be one of the most widespread and long-lasting changes on a global scale. Our understanding that microplastics significantly impact terrestrial systems are change stressor continues grow. In present study, we investigated negative effect long-term (28 days exposure in food) polystyrene particles micro (1.0-1.9 µm, 0.4-0.6 µm) nano (0.04-0.06 scale, low doses, fruit fly - representing common, globally distributed invertebrate, model species many fields....
Abstract Cell-to-cell signalling is a major mechanism controlling plant morphogenesis. Transport of molecules through plasmodesmata one way in which plants promote or restrict intercellular over short distances. Plasmodesmata are membrane-lined pores between cells that regulate the flow changes their size, creating symplasmic fields connected cells. Here we examine role and communication establishment cell totipotency, using somatic embryo induction from Arabidopsis explants as model system....
Earthworm (Megadrili) ovaries are paired organs located usually in the XIII segment. So far, only their localization and general morphology well known. Light, fluorescence, electron microscopy analyses were carried out to describe ovary histology ultrastructure selected representatives of family Lumbricidae. We studied 12 species from six genera: Aporrectodea, Dendrobaena, Eisenia, Lumbricus, Octolasion, Proctodrilus. It was revealed that Lumbricidae tiny, leaf-like structures with one...
Pancreatic ductal adenocarcinoma (PDAC) is recognized as one of the most formidable cancers, largely due to its distinct microenvironment characterized predominantly by extensive desmoplastic stroma. In this study, we synthesized three novel water-soluble fullerene-based nanomaterials targeting EGFR protein. The direct amination fullerene carbon atoms, was followed conjugation with a modified derivative inhibitor-erlotinib, resulting in formation derivatives. Further investigation into PAN02...
In Utricularia nelumbifolia , the nuclei of placental nutritive tissue possess unusually shaped projections not known to occur in any other flowering plant. The main aim study was document morphology and ultrastructure these unusual nuclei. addition, literature searched find examples nuclear tubular plant groups, closely related species (i.e. sects Iperua Orchidioides Foliosa ) were examined.
We studied the organization of F-actin and microtubular cytoskeleton in male germ-line cysts seminal vesicles earthworm Dendrobaena veneta using light, fluorescent electron microscopy along with both chemically fixed tissue life cell imaging. Additionally, order to follow functioning cytoskeleton, we incubated colchicine, nocodazole, cytochalasin D latrunculin A. The cells D. are interconnected via stable intercellular bridges (IB), form syncytial cysts. Each germ has only one IB that...
Two eye-colour mutant strains, white (W) and yellow (Y) of house cricket Acheta domesticus were established in our laboratory. We phenotyped genotyped the mutants, performed genetic crossings studied eye structure pigment composition using light electron microscopy biochemical analysis. show that W Y phenotypes are controlled by a single autosomal recessive allele, as both traits metabolically independent. The analysis mutants`eye showed reduced number dark granules while simultaneously, an...
The main goal of the article is to describe ovary organization and oogenesis in Peristodrilus montanus, an aquatic oligochaete subfamily Rhyacodrilinae. presented analysis will not only enrich knowledge about how eggs are formed but, because suggested conservatism clitellate annelids, can contribute disentangling complex phylogenetic relationships rhyacodrilines within Naididae. paired, conically shaped ovaries located segment XI. They composed a dozen or so syncytial germ-line cysts, which...
Abstract The syncytial groups of germ cells (germ-line cysts) forming in ovaries clitellate annelids are an attractive model to study mitochondrial stage-specific changes. Using transmission electron microscopy, serial block-face scanning and fluorescent we analyzed the mitochondria distribution morphology state membrane potential female cysts Enchytraeus albidus. We visualized 3D at ultrastructural level successive stages: 2-celled, 4-celled, 16-celled cysts, cyst advanced oogenesis. found...
Ovaries in earthworms belonging to the family Megascolecidae are paired structures attached septum anterior part of XIII segment. They fan rosette shaped with numerous rows growing oocytes, known as egg strings, radiating from ovary center towards segmental cavity. The histological and ultrastructural organization megascolecids course oogenesis remain unknown. paper presents results light electron microscopy analyses ovaries six megascolecid species, three genus Amynthas Metaphire. Both...

Mitochondria change their morphology and distribution depending on the metabolism functional state of a cell. Here, we analyzed mitochondria selected structures in female germ-line cysts representative clitellate annelids – white worm Enchytraeus albidus which each germ cell has one cytoplasmic bridge that connects it to common mass. Using serial block-face scanning electron microscopy (SBEM), prepared three-dimensional ultrastructural reconstructions entire compartments cyst at advanced...
Abstract Natural origin substances are an important source of medicinal compounds and have been used for centuries as remedies many ailments. One these is earthworm (EW) coelomic fluid (CF). In this paper, we present the effects Dendrobaena veneta CF on HCT116, A549 BEAS-2B cell lines. We two fractions CF, one heated to 70°C (CF-H) unheated (CF-NH). Moreover, different sets doses: high doses (500, 250, 125, 62.5 µg/ml) low (16, 8, 4 µg/ml). Our results showed no cancer-selective cytotoxicity...
