Diversity of , Giles (Diptera: Culicidae) Larval Habitats in Urban Areas and Malaria Transmission in Bouaké, Côte d'Ivoire.

Vector Borne Zoonotic Dis 2021 Jun 14. Epub 2021 Jun 14.

Maladies Infectieuses et Vecteurs, Ecologie, Génétique, Evolution et Contrôle, IRD, CNRS, Université de Montpellier, Montpellier, France.

Malaria vectors are supposedly uncommon in urban areas owing to the lack of suitable breeding sites for their development. However, the maintenance in urban areas of traditional rural practices along with humanitarian crisis can create favorable conditions for malaria transmission. This study aimed to provide relevant entomological data on the risk of malaria transmission in the city of Bouaké, after the military-political crisis from 2002 to 2011 in Côte d'Ivoire. Read More

Increased complexity of t(11;14) rearrangements in plasma cell neoplasms compared to mantle cell lymphoma.

Genes Chromosomes Cancer 2021 Jun 14. Epub 2021 Jun 14.

Division of Hematopathology, Department of Laboratory Medicine and Pathology, Mayo Clinic, Rochester, MN.

Plasma cell neoplasms (PCN) and mantle cell lymphoma (MCL) can both harbor t(11;14)(q13;q32) (CCND1/IGH), usually resulting in cyclin D1 overexpression. In some cases, particularly at low levels of disease, it can be morphologically challenging to distinguish between these entities in the bone marrow (BM) since PCN with t(11;14) are often CD20-positive with lymphoplasmacytic cytology, while MCL can rarely have plasmacytic differentiation. We compared the difference in CCND1/IGH by fluorescence in situ hybridization (FISH) in PCN and MCL to evaluate for possible differentiating characteristics. Read More

Department of Anesthesiology, Amberg Hospital, Mariahilfbergweg 7, 92224 Amberg, Germany.

Introduction: In the animal model, preconditioning is a powerful weapon against ischemic damage. The reason why the human heart cannot be protected from ischemic damage by preconditioning remains unclear. There are assumptions that the lack of preconditioning in humans is caused by concomitant diseases such as dyslipoproteinemia and arteriosclerosis. Read More

Leukodepletion Filters-Derived CD34+ Cells As a Cell Source to Study Megakaryocyte Differentiation and Platelet Formation.

J Vis Exp 2021 May 20(171). Epub 2021 May 20.

BPPS UMR-S 1255, FMTS, Université de Strasbourg, INSERM, EFS Grand Est;

The in vitro expansion and differentiation of human hematopoietic progenitors into megakaryocytes capable of elongating proplatelets and releasing platelets allows an in-depth study of the mechanisms underlying platelet biogenesis. Available culture protocols are mostly based on hematopoietic progenitors derived from bone marrow or cord blood raising a number of ethical, technical, and economic concerns. If there are already available protocols for obtaining CD34 cells from peripheral blood, this manuscript proposes a straightforward and optimized protocol for obtaining CD34+ cells from leukodepletion filters readily available in blood centers.

Fibroma of tendon sheath is defined by a USP6 gene fusion-morphologic and molecular reappraisal of the entity.

Mod Pathol 2021 Jun 4. Epub 2021 Jun 4.

Institute of Pathology, Faculty of Medicine, University of Ljubljana, Korytkova 2, Ljubljana, Slovenia.

Fibroma of tendon sheath (FTS) is an uncommon benign myofibroblastic neoplasm that arises in association with tenosynovial tissue. Fusions of the USP6 gene have been recently documented in a proportion of so-called "cellular FTS" but not in "classic FTS". It remains unknown whether FTS can be defined by a USP6 fusion, regardless of cellularity, and what are USP6 fusion-negative "cellular FTS". Read More

Mol Biol Rep 2021 May 31. Epub 2021 May 31.

Department of Molecular Biology Genetics, İstanbul Medeniyet University, İstanbul, Turkey.

Teratozoospermia is a condition related to poor morphologically normal sperm count below the lower reference limit, which could hinder natural conception. Single nucleotide polymorphisms (SNPs) in the genes involved in sperm production and testicular function are proved to be risk factors, resulting in decreased sperm parameters and defects in sperm morphology. c.

Molecular Diversity of Aspergilli in Two Iranian Hospitals.

Mycopathologia 2021 May 30. Epub 2021 May 30.

Westerdijk Fungal Biodiversity Institute, Utrecht, The Netherlands.

The Aspergillus species are main causative agents of various infections such as invasive aspergillosis (IA) in immunocompromised patients and these infections have high mortality rates. In this study, we provide insight in the species causing aspergillosis in Iran based on morphology and sequence data. Clinical (n = 117) and environmental isolates (n = 54) collected during 2010-2016 from University hospitals in Mashhad and Tehran (Iran) were identified both morphologically and molecularly using partial calmodulin (CaM) gene sequences.

Morphological and genetic identification of fungal genus/species in formalin-fixed, paraffin-embedded specimens obtained from patients with histologically proven fungal infection.

Mycoses 2021 May 24. Epub 2021 May 24.

Department of Pathology, National Institute of Infectious Diseases, Tokyo, Japan.

Background: Although fungi are found relatively easily by microscopic examination of pathological samples, identification of fungal genus and species in pathological samples is not easy because the morphological features of fungi are similar among genera and species.

Objectives: A multiple real-time PCR was developed for identification of fungal genus/species, and morphological characterizations of fungi were analysed in pathological samples.

Patients/methods: Seventy-five formalin-fixed paraffin-embedded (FFPE) samples morphologically proven to contain any fungus were examined. Read More
