Waldenstrom macroglobulinemia (WM) is a rare type of non-Hodgkin lymphoma with great heterogeneity, and the data of peripheral blood T-lymphocyte subsets in WM are limited. This study aimed to investigate the clinical correlation and distribution of circulating T-lymphocyte subsets in newly diagnosed WM patients. We retrospectively searched medical records for 86 newly diagnosed WM patients. Comparisons of the absolute CD3+ T-lymphocyte count (ACD3C), CD4+ T-lymphocyte count (ACD4C), CD8+ T-lymphocyte count (ACD8C), and CD4+/CD8+ T-lymphocyte ratio (CD4+/CD8+) as continuous parameters in different groups were calculated. Univariate and multivariate analyses were used to assess prognostic factors for overall survival (OS) and progression-free survival (PFS). Young patients ( less then 65 years) had lower ACD8C levels and a higher CD4+/CD8+ ratio. And the lower level of β2-microglobulin ( less then 3 mg/L) was associated with a higher CD4+/CD8+ ratio. With a median follow-up of 25 months, the univariate survival analysis showed that CD4+/CD8+ ratio inversion (CD4+/CD8+ less then 1.5) was associated with shorter OS and PFS, and multivariate analysis confirmed that inverted CD4+/CD8+ ratio could be an independent adverse prognostic factor for OS and PFS. Additionally, initial treatment with rituximab or bortezomib significantly improved the PFS and OS of CD4+/CD8+ inversion patients but did not affect normal CD4+/CD8+ patients. We show that low circulating CD4+/CD8+ ratio at diagnosis is an adverse prognostic factor in WM patients and that first-line therapy which included rituximab or bortezomib significantly improved PFS and OS for patients with CD4+/CD8+ ratio less than 1.5.Salvia multicaulis has been an important medicinal plant in Iran and several East Asian countries for hundreds of years. Because of growing demand, overharvesting of wild S. multicaulis has endangered its wild populations. Endophytes are well known for protecting wild plant populations against biotic and abiotic stresses, especially under harsh situations, as well as for their plant growth enhancement activities. Since no information was on endophyte biology in S. multicaulis, here we aimed at analyzing diversity and spatiotemporal distribution of fungal endophytes associating S. multicaulis in their main wild habitats in Iran, i.e., Qazvin, Alborz and Mazandaran provinces. A total of 153 fungal endophytes were isolated and identified according to their morphology and ribosomal ITS rDNA sequences. As results indicated Ascomycota dominated in colonizing S. multicaulis with a relative frequency (RF) of 96.77%, comprising of Eurotiomycetes (RF 40.5%), Sordariomycetes (RF 33.9%) and Dothideomycetes (RF 20.5%). Mupe and season can affect the fungal endophyte composition of this medicinal plant. This knowledge could be further applied in protection and health management of this endangered species.Phaseolus vulgaris is originally from the American continent. It is renowned as one of the preferred legume choice in the Peruvian market, due to its high content of nutrients. The Peruvian coast valleys are key-production areas for local varieties of the common bean crops. Soil-borne plant pathogens, however, favored by soil and environmental conditions, may reduce crop production. The aim of this study was to conduct a bio prospection of the antagonistic native bacteria of the north, south and central part of the coastal areas related to the common bean. A collection of 26 strains isolated from the rhizosphere of common bean plants showed high potential to control the growth of Sclerotinia, Fusarium and Rhizoctonia due to the production of both volatile and non-volatile organic compounds. Most of the strains were able to suppress fungal growth due to the presence of non-volatile organic compounds, such as hydrolytic enzymes, siderophores and antifungal lipopeptide production. Bacillus IcBac2.1 strain showed a remarkable ability to halt the majority of phytopathogens producing antifungal lipopeptides. The crude lipopeptides were soluble in polar solvents and remained stable at high temperatures and low pH. Strains were also able to inhibit fungal growth through volatile organic compounds. Alcaligenes TvPs2.4 and Pseudomonas TvPs1.6 showed the highest inhibition strength against the tested phytopathogens. Each strain produced 21 volatile organic compounds detected by SPME/GC-MS analysis. The compounds with the highest concentration were dimethyl disulfide and D-limonene. The 16S rRNA gene sequence confirmed that the strains were closely related to Bacillus, Paenibacillus, Achromobacter, Pseudomonas, Serratia and Alcaligenes.Phycosphere hosts the boundary of unique holobionts harboring dynamic algae-bacteria interactions. During our investigating the microbial consortia composition of phycosphere microbiota (PM) derived from diverse harmful algal blooms (HAB) dinoflagellates, a novel rod-shaped, motile and faint yellow-pigmented bacterium, designated as strain LZ-6 T, was isolated from HAB Alexandrium catenella LZT09 which produces high levels paralytic shellfish poisoning toxins. Phylogenetic analysis based on 16S rRNA gene and two housekeeping genes, rpoA and pheS sequences showed that the novel isolate shared the highest gene similarity with Marinobacter shengliensis CGMCC 1.12758 T (99.6%) with the similarity values of 99.6%, 99.9% and 98.5%, respectively. Further phylogenomic calculations of average nucleotide identity (ANI), average amino acid identity (AAI) and digital DNA-DNA hybridization (dDDH) values between strains LZ-6 T and the type strain of M. shengliensis were 95.9%, 96.4% and 68.5%, respectively. However, combined phenotypic and chemotaxonomic characterizations revealed that the new isolate was obviously different from the type strain of M. shengliensis. The obtained taxonomic evidences supported that strain LZ-6 T represents a novel subspecies of M. shengliensis, for which the name is proposed, Marinobacter shengliensis subsp. alexandrii subsp. nov. with the type strain LZ-6 T (= CCTCC AB 2018388TT = KCTC 72197 T). This proposal automatically creates Marinobacter shengliensis subsp. selleck chemicals shengliensis for which the type strain is SL013A34A2T (= LMG 27740 T = CGMCC 1.12758 T).
