Anaplastic large cell T-cell lymphoma: insights from cytological and immunological profiles across ten diverse cases.
Ann Biol Clin (Paris)
December 2024
Hematology Laboratory, Hospices Civils de Lyon, Centre Hospitalier Lyon Sud, Lyon, France.
While the latest WHO classification of hematological neoplasms helps refine the diagnostic criteria for anaplastic large cell lymphomas (ALCL), their diagnosis can still be challenging. This retrospective series of 10 ALCL cases illustrates the cytological appearance and immunological profile obtained through flow cytometry (FCM) from various sample types, including lymph node biopsies (LN), peripheral blood (PB), cerebrospinal fluid (CSF), and pleural fluid (PF). ALCL exhibits a polymorphic cytological appearance, ranging from "doughnut" cells to Hodgkin-like cells, very large cells, and small cells, with this polymorphism being particularly pronounced in ALK (-) forms.

Protoderm formation is a crucial step in early embryo patterning in plants, separating the precursors of the epidermis and the inner tissues. Although key regulators such as ARABIDOPSIS THALIANA MERISTEM LAYER1 (ATML1) and PROTODERMAL FACTOR2 (PDF2) have been identified in the model plant Arabidopsis thaliana, the genetic pathways controlling protoderm specification remain largely unexplored. Here, we combined genetic, cytological, and molecular approaches to investigate the regulatory mechanisms of protoderm specification in Arabidopsis thaliana.

Department of Laboratory Medicine, Nanfang Hospital, Southern Medical University, Guangzhou, Guangdong, 510515, P. R. China.
Background: This study aimed to investigate the potential utility of Epithelial-mesenchymal transition (EMT) signaling cell detection in the early diagnosis of cervical lesions.
Methods: Enrichment of cervical epithelial cells was carried out using a calibrated membrane with 8-μm diameter pores. RNA-in situ hybridization (RNA-ISH) was employed to detect and characterize EMT cells utilizing specific EMT markers.
Comparative transcriptome analysis and heterologous overexpression indicate that the ZjZOG gene may positively regulate the size of jujube fruit.

Background: Fruit size is a crucial economic trait that impacts the quality of jujube (Ziziphus jujuba), however, research in this area remains limited. This study utilized two jujube cultivars with similar genetic backgrounds but differing fruit sizes to investigate the regulatory mechanisms affecting fruit size through cytological observations, transcriptome sequencing, and heterologous overexpression.
Results: The findings reveal that variations in mesocarp cell numbers during early fruit development significantly influence final fruit size.

Introduction: Rye ( L.) played a very important role in wheat genetic improvement and forage production worldwide. However, since rye is a kind of cross-pollinated plant, high levels of genetic heterozygosity and heterogeneity existed in the genome.
