Influence of different types of sterile cytoplasms (A3, A4, 9E) on the combining ability of CMS lines of sorghum.

Vavilovskii Zhurnal Genet Selektsii 2020 Oct;24(6):549-556

Agricultural Research Institute of the South-East Region of Russia, Saratov, Russia.

Investigation of the effect of the cytoplasm on the combining ability (CA) of lines with cytoplasmic male sterility (CMS) is of considerable interest in terms of understanding the genetic functions of the cytoplasm and for practical purposes to create hybrids with improved economically valuable traits. In order to investigate the effect of different types of sterile cytoplasm (A3, A4, 9E) on CA in sorghum, we studied the manifestation of a number of biological and agronomic traits in 54 F1 hybrid combinations obtained using iso-nuclear CMS lines with the nuclear genome of the line Zheltozernoye 10, differing only in the types of sterile cytoplasm (A3, A4 and 9E). Eighteen varieties and lines of grain sorghum developed at the Russian Research and Project-technological Institute of Sorghum and Maize were used as paternal parents. Read More

Assessing the Role of Gay Community Attachment, Stigma, and PrEP Stereotypes on Young Men Who Have Sex with Men's PrEP Uptake.

AIDS Behav 2020 Nov 19. Epub 2020 Nov 19.

Department of Family and Community Health, University of Pennsylvania School of Nursing, 418 Curie Boulevard 243L, Philadelphia, PA, 19104, USA.

Negative stereotypes about pre-exposure prophylaxis (PrEP) hinder PrEP uptake among young men who have sex with men (YMSM). Prior research suggests community homophobia may be linked to negative PrEP attitudes. Conversely, individuals with high gay community attachments (GCA) may have more access to credible PrEP information/resources. Read More

Temporal artery biopsy for suspected giant cell arteritis: a retrospective analysis.

Rheumatol Int 2020 Nov 6. Epub 2020 Nov 6.

Division of Rheumatology, Department of Internal Medicine, Eskişehir Osmangazi University, Eskişehir, 26480, Turkey.

Temporal artery biopsy (TAB) is one of the diagnostic criteria of giant cell arteritis (GCA) according to 1990 ACR criteria and remains a tool for diagnosis. Although clinicians perform TAB with an intent to confirm suspected GCA, some biopsies result in negative and some lead to non-GCA diagnoses. We aim to review the diagnoses after TAB biopsy performed for suspected GCA and also wanted to evaluate the diagnostic changes and concomitant diseases that develop over time. Read More

Interval-valued intuitionistic fuzzy MADM method based on TOPSIS and grey correlation analysis.

Math Biosci Eng 2020 08;17(5):5584-5603

National Key Laboratory of Science and Technology on ATR, College of Electronic Science, National University of Defence Technology, Changsha 410000, China.

In this paper, we propose an interval-valued intuitionistic fuzzy Multi-Attribute Decision Making (MADM) method based on improved TOPSIS and Grey Correlation Analysis (GCA), in which the attribute values are interval-valued intuitionistic fuzzy numbers. So that we can deal with imprecise information in fuzzy and rough form in MADM problems by using interval-valued intuitionistic fuzzy numbers Firstly, the concept of interval intuitionistic fuzzy entropy is introduced to calculate the entropy weight of attributes. And the combined weight is calculated by combining the entropy weight with the subjective weight. Read More

sp. nov. and sp. nov., Isolated from the Discovery Deep Brine-Seawater Interface in the Red Sea.

Microorganisms 2020 Sep 25;8(10). Epub 2020 Sep 25.

Red Sea Research Center, King Abdullah University of Science and Technology, Thuwal Jeddah 23955-6900, Saudi Arabia.

Two extremely halophilic archaeal strains, designated SB29 and SB3, were isolated from the brine-seawater interface of Discovery Deep in the Red Sea. Cells of both strains were pleomorphic (irregular polyhedrals, ovals, and rods) and stained Gram-negative; colonies were pigmented pink. The sequence similarity of the 16S rRNA gene of strain SB29 with that of its most closely related validly described species ( DSM 16227) and that of strain SB3 with its closest validly described relative ( ATCC 35960) was 98.

Full-field optical coherence tomography for the diagnosis of giant cell arteritis.

PLoS One 2020 31;15(8):e0234165. Epub 2020 Aug 31.

Department of Internal Medicine and Clinical Immunology, François Mitterrand Hospital, Dijon University Hospital, Dijon, Bourgogne-Franche-Comté, France.

Histopathological examination of temporal artery biopsy (TAB) remains the gold standard for the diagnosis of giant cell arteritis (GCA) but is associated with essential limitations that emphasize the need for an upgraded pathological process. This study pioneered the use of full-field optical coherence tomography (FF-OCT) for rapid and automated on-site pathological diagnosis of GCA. Sixteen TABs (12 negative and 4 positive for GCA) were selected according to major histopathological criteria of GCA following hematoxylin-eosin-saffron-staining for subsequent acquisition with FF-OCT to compare structural modifications of the artery cell wall and thickness of each tunica.
