in this study, the bacterial diversity in the activated sludge system of a full-scale municipalwastewater treatment plant in dubai was monitored over a period of one year using ribosomal rna (rrna)targeted oligonucleotide probes for a defined phylogenetic group of bacteria by the fluorescence in situhybridization (fish) technique. the largest fraction of the bacterial community in the sludge sa...

Reactive immunoblastic proliferations can histologically mimic classical Hodgkin lymphoma (CHL), and show diffuse CD30 expression in large cells. The lack of expression of CD15 in a subset of CHL further complicates their separation from immunoblastic proliferations. Loss of expression of B-cell transcription factors is frequently exploited in making a diagnosis of CHL; however, the staining pa...

BACKGROUND Detection of B cell clonality is useful for assisting in the diagnosis of B cell lymphomas. Clonality assessment can be accomplished through evaluation of KAPPA and LAMBDA light chain expression. Currently, only slide based methods are available for the majority of patient biopsies and do not detect light chain protein or mRNA in many B-cell lymphomas. Herein we evaluated a new metho...

AIM To identify and characterize cancer stem cells (CSC) in moderately differentiated buccal mucosa squamous cell carcinoma (MDBMSCC). METHODS Four micrometer-thick, formalin-fixed, paraffin-embedded MDBMSCC samples from six patients underwent 3,3-diaminobenzidine (DAB) immunohistochemical (IHC) staining for the embryonic stem cell (ESC) markers, NANOG, OCT4, SALL4, SOX2, and pSTAT3; cancer s...

Recent evidence suggests that m6A modifications regulate the progressions of several types of tumors. YTHDF2, an m6A reader, has been implicated in the regulation of hepatocellular carcinoma (HCC). miR-493-3p has been defined as tumor suppressor that inhibits the progressions of several types of cancers. However, the functions and mechanisms of YTHDF2 and the indirect m6A regulated role of miR-...
