Endopolyploidy Variation in Wild Barley Seeds across Environmental Gradients in Israel.

Genes (Basel) 2021 May 10;12(5). Epub 2021 May 10.

Centre of the Region Haná for Biotechnological and Agricultural Research, Institute of Experimental Botany, Czech Academy of Sciences, Šlechtitelů 31, 779 00 Olomouc, Czech Republic.

Wild barley is abundant, occupying large diversity of sites, ranging from the northern mesic Mediterranean meadows to the southern xeric deserts in Israel. This is also reflected in its wide phenotypic heterogeneity. We investigated the dynamics of DNA content changes in seed tissues in ten wild barley accessions that originated from an environmental gradient in Israel. Read More

Arch Virol 2021 Mar 12;166(3):779-788. Epub 2021 Jan 12.

The Roslin Institute, University of Edinburgh, Midlothian, UK.

Ungulate protoparvovirus 1, also known as porcine parvovirus 1 (PPV1), is considered to be one of the major causes of reproductive failure in pig breeding herds. Other parvoviruses have also been identified in pigs, including ungulate tetraparvovirus 3, or PPV2, ungulate tetraparvovirus 2, or PPV3, and ungulate copiparvovirus 2, or PPV4, but their significance for pigs is unknown. In the present study, the prevalence of PPV1-4 was investigated using a total of 231 lung and serum samples collected from slaughterhouses in 13 provinces throughout Vietnam. Read More

The Effect of Abiotic Factors on Abundance and Photosynthetic Performance of Airborne Cyanobacteria and Microalgae Isolated from the Southern Baltic Sea Region.

Cells 2021 Jan 8;10(1). Epub 2021 Jan 8.

Department of Marine Physics, Institute of Oceanology Polish Academy of Sciences, P-81-779 Sopot, Poland.

Cyanobacteria and microalgae present in the aquatic or terrestrial environment may be emitted into the air and transported along with air masses over long distances. As a result of staying in the atmosphere, these organisms may develop a greater tolerance to stressful factors, but this topic is still relatively unknown. The main aim was to show an autecological characteristic of some airborne microalgae and cyanobacteria strains by a factorial laboratory experiment approach, including changes in irradiance, temperature, and salinity conditions.

Ticks Tick Borne Dis 2021 01 25;12(1):101558. Epub 2020 Sep 25.

CEITEC - Central European Institute of Technology, University of Veterinary and Pharmaceutical Sciences Brno, Palackého třída 1946/1, Brno, 612 42, Czech Republic; Department of Pathology and Parasitology, University of Veterinary and Pharmaceutical Sciences, Palackého 1946/1, 612 42, Brno, Czech Republic; Biology Centre, Institute of Parasitology, Czech Academy of Sciences, Branišovská 31, 37005, České Budějovice, Czech Republic; Department of Botany and Zoology, Faculty of Science, Masaryk University, Kotlářská 2, 611 37, Brno, Czech Republic.

Low-Level Rifampin Resistance and Mutations in Mycobacterium tuberculosis: an Analysis of Whole-Genome Sequencing and Drug Susceptibility Test Data in New York.

J Clin Microbiol 2021 Mar 19;59(4). Epub 2021 Mar 19.

Wadsworth Center, New York State Department of Health, Albany, New York, USA

Rapid and reliable detection of rifampin (RIF) resistance is critical for the diagnosis and treatment of drug-resistant and multidrug-resistant (MDR) tuberculosis. Discordant RIF phenotype/genotype susceptibility results remain a challenge due to the presence of mutations that do not confer high levels of RIF resistance, as have been exhibited in strains with mutations such as Ser450Leu. These strains, termed low-level RIF resistant, exhibit elevated RIF MICs compared to fully susceptible strains but remain phenotypically susceptible by mycobacterial growth indicator tube (MGIT) testing and have been associated with poor patient outcomes.

A novel ex vivo protocol to mimic human walking gait: implications for Duchenne muscular dystrophy.

J Appl Physiol (1985) 2020 10 3;129(4):779-791. Epub 2020 Sep 3.

Department of Human Nutrition, Foods, and Exercise and Metabolism Core, Virginia Tech, Blacksburg, Virginia.

We developed a novel ex vivo mouse protocol to mimic in vivo human soleus muscle function predicted by musculoskeletal simulations to better understand eccentric contractions during gait and ultimately to better understand their effects in Duchenne muscular dystrophy (DMD) muscles. DMD muscles are susceptible to eccentric injury because the protein dystrophin is absent. The mouse, a DMD model that also lacks dystrophin, is often subjected to ex vivo acute but nonphysiological eccentric injury protocols. Read More

Plasmid stability of potential probiotic Lactobacillus plantarum strains in artificial gastric juice, at elevated temperature, and in the presence of novobiocin and acriflavine.

Arch Microbiol 2021 Jan 16;203(1):183-191. Epub 2020 Aug 16.

Department of Food Engineering, Faculty of Engineering, Süleyman Demirel University, Isparta, Turkey.

In this study, the presence of plasmids responsible for carbohydrate fermentation and antibiotic resistance and the stability of these plasmids in artificial gastric juice were investigated in 20 Lactobacillus plantarum strains with probiotic properties. Plasmid curing was performed with novobiocin, acriflavine and elevated incubation temperature to identify plasmids encoded with carbohydrate fermentation and antibiotic resistance genes and to compare them with artificial gastric juice. Plasmid profiling of the strains revealed that 100% of the strains were harbouring plasmids in varying sizes and numbers. Read More

Beware of whom you live with: Your intestinal IgA may depend on it.

Eur J Immunol 2020 06 12;50(6):779-782. Epub 2020 May 12.

Unité Lymphocytes et Immunité, Institut Pasteur, Paris, France.

In the past 15 years, it became clear that the symbiotic microbiota has an important impact on the development and regulation of the immune system. Consequently, it is incorrect to interpret a phenotype solely as a direct result of the genotype, without considering the impact of the microbiota. In fact, ignorance of the effects exerted by the microbiota may account for a large part of the "replication issues" found in many studies. Read More

J Sci Food Agric 2019 Dec 10;99(15):6911-6921. Epub 2019 Oct 10.

Engineering Research Center of Chinese Ministry of Education for Edible and Medicinal Fungi, Jilin Agricultural University, Changchun, P. R. China.

Background: This study aimed to evaluate the possibility of cotton waste enrichment with glycine betaine (GB) for production of two strains (P9, P10) of king oyster (Pleurotus eryngii). Cotton waste was used as (100%) control (T0 = cotton waste) and augmented with various combinations of GB, (T1 = 2 mmol L , T2 = 4 mmol L , T3 = 6 mmol L , T4 = 8 mmol L and T5 = 10 mmol L ). The response of king oyster to GB was evaluated by earliness, yield, biological efficiency (BE), minerals (nitrogen, phosphorus, potassium, zinc (Zn), copper (Cu), magnesium (Mg), manganese (Mn), iron (Fe), sodium (Na), calcium (Ca)), total sugars, total soluble solids, reducing sugars, non-reducing sugars, ascorbic acid, proximate (crude protein, carbohydrates, crude fibers, ash, fats) content of fruiting body and Fourier-transform infrared (FTIR) spectroscopy analysis compared with the control substrate (cotton waste).
