Research ArticleOpen accessEvery word in the titleStructure, Ultrastructure of the Anther, Pollen Microsporogenesis and Morphology of Pollen Grains of Two Populations of Lygeum spartum L. in AlgeriaKatia Abdeddaim-Boughanmi, Meriem Kaid-HarcheProblem statement: The Lygeum spartum L. represented by a single species occupies several regions of the Mediterranean basin. This plant plays an important ecological role in the fight against desertification and economic development in the manufacture of paper pulp. Approach: However, the cytogenetic studies in mitosis in this species revealed the existence of two ploidy levels: 2n = 40 among … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 8,514 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAnalysis of Photosynthetic Pigment Content and Leaf Structure of Pteroceltis Tatarinowii Mutant with Yellow LeafYongchang Yu, Chen Lv, Min Liu, Tiantian ChenThe relationship betweenleaf variation characteristics and leaf structure characteristics of Pteroceltistatarinowii with yellow leaf was explored to provide a theoretical basisfor the breeding of other ornamental plants. In this study, the differences inpigment content, leaf structure, and chloroplast ultrastructure in leaves of Pteroceltistatarinowii mutant with yellow leaf 'Huiguang' and its original species'Lingyansi No. 1’ were studied. The results showed that … …American Journal of Biochemistry and Biotechnology, Vol. 18, Issue 3 · 20 Sep 2022 · 5,598 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStructural Organization of Vitelline Cells of Trematode with Undifferentiated Body of Azygia Lucii (Muller, 1776)Rimma Meyramovna Ualiyeva, Sayan Berikovich Zhangazin, Indira Bulatovna AltayevaIt is known that the class Trematoda includes exclusively parasitic forms of flatworms. In this regard, they have formed a variety of morphological and functional adaptations to a parasitic lifestyle. One of them is the colossal fecundity, which provides the possibility of rapid and wide settlement and detection of hosts. Therefore, the study of the sexual reproduction of helminths is … …OnLine Journal of Biological Sciences, Vol. 22, Issue 1 · 26 Jan 2022 · 6,378 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUltrastructural Morphology of the Muscle System Organization in the Trematode Typhlocoelium cucumerinumIrina Yurievna Chidunchi, Ainagul Balgauovna Kaliyeva, Natalya Petrovna Korogod et al.Trematodes, also known as flatworms, are a diverse group of parasitic organisms that live in a variety of ecosystems, from freshwater to marine habitats. Their complex life cycle often involves intermediate and definitive hosts and multiple developmental stages. Trematodes have unique morphological features that allow them to adapt, move and parasitize within host tissues and organs. The parasitic lifestyle of … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 1 Jun 2024 · 5,112 accessesView PDFCite
Research ArticleOpen accessIn the keywordsUltrastructural Organization of the Muscular System Body of the Trematode Schistogonimus RarusIrina Yurievna ChidunchiIt is known that parasitic flatworms of the class Trematoda have a unique complex life cycle, and have morphological features of adaptation, movement, and existence in the host body. Functional peculiarities of the parasitic way of life are conditioned by the developed muscular system, due to which there is movement and attachment of the snail to various organs of the … …OnLine Journal of Biological Sciences, Vol. 24, Issue 1 · 16 Nov 2023 · 4,854 accessesView PDFCite
Research ArticleOpen accessIn the keywordsFunctional Role of Vitelline Glands and Mehlis Gland in the Process of Resistant Egg Shell Formation in TrematodesRimma UaliyevaThe study of the functional morphology of the reproductive system of trematodes, as well as its individual parts, provides an opportunity to solve an important problem that plays a huge role in theoretical and practical terms as the directed regulation of the fecundity of endoparasites. The article is devoted to the study of the functional role of vitelline glands and … …OnLine Journal of Biological Sciences, Vol. 23, Issue 2 · 28 Feb 2023 · 6,367 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSome Morphologic Features of Heart Failure with Different EtiologyDmitrij Arkadievich OleynikovDilated Cardiomyopathy (DCM) and Chronical Degenerative Valvular Disease (CDVD) are very common in dogs nowadays. However, due to modern level in oncology we can meet chemotherapy-induced cardiomyopathies more often. We have lack of information about pathogenic mechanisms underlying doxorubicin-induced cardiomyopathy (DoxCM) and features differentiating it from CDVD and DCM. The study population consisted of 46 dogs of different age, sex … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 2 · 20 May 2017 · 7,330 accessesView PDFCite

Research ArticleOpen accessIn the abstractUltrastructural and Circadian Morphometric Characteristics of Rat Pinealocytes Under Physiological and Toxic ConditionsAnna I. Anurkina, David A. Areshidze, Maria A. Kozlova, Valery P. ChernikovCarbon tetrachloride (CCl₄) exhibits pronounced neurotoxic effects following acute or chronic exposure. Recent studies indicate that the pineal gland responds to CCl₄ intoxication by altering its secretory function, although detailed ultrastructural changes in pinealocytes remain inadequately investigated. This research addresses the urgent need to elucidate the mechanisms of CCl₄ toxicity on the pineal gland, which could contribute to developing strategies … …OnLine Journal of Biological Sciences, Vol. 26, Issue 2 · 1 Jun 2026 · 1,170 accessesView PDFCite
