Efficacy of nanoparticle encapsulation on suppressing oxidation and enhancing antifungal activity of cyclic lipopeptides produced by Bacillus subtilis.

Colloids Surf B Biointerfaces 2020 Jun 1;193:111143. Epub 2020 Jun 1.

Department of Food Science and Engineering, College of Biological Sciences and Technology, Beijing Key Laboratory of Forest Food Processing and Safety, Beijing Forestry University, Beijing, 100083, China. Electronic address:

This study examined the storage instability of cyclic lipopeptides (CLs) extracted from Bacillus subtilis culture; CLs were easily oxidized and therefore quickly lost antifungal activity during storage. Solid lipid nanoparticle (SLN) encapsulation effectively suppressed the oxidation and prolonged and enhanced the antifungal efficacy of CLs through controlled release. Thermal gravimetric analysis, X-ray diffraction, and Fourier transform infrared spectroscopy revealed that hydrophobic interactions between the fatty acid moieties of CLs and SLNs fortified the crystal structure of the CL-SLN complex, thereby improving the storage stability of the encapsulated CLs.

Biomarker responses in terrestrial gastropods exposed to pollutants: A comprehensive review.

Chemosphere 2020 May 27;257:127218. Epub 2020 May 27.

Department of Animal Pests, Plant Protection Research Institute, Agricultural Research Center, Alexandria, Egypt.

The chemical contamination of terrestrial ecosystems is a great concern as these ecosystems are the target of most of the pollutants derived from anthropogenic activities such as pesticides, heavy metals, nanoparticles, and others. Terrestrial gastropods are considered to be excellent sentinel organisms for biological monitoring of environmental pollution, as they have the ability to accumulate chemicals in their tissues and exhibit a great potential to evaluate the ecological effects of pollutants in terrestrial ecosystems. The use of biomarkers as sensitive parameters to estimate the exposure or resulting effects of chemicals have received considerable attention. Read More

The C-terminal 17 amino acids of the photoreceptor UVR8 is Involved in the fine-tuning of UV-B signaling.

J Integr Plant Biol 2020 Jun 3. Epub 2020 Jun 3.

Joint Center for Single Cell Biology, Key Laboratory of Urban Agriculture Ministry of Agriculture, School of Agriculture and Biology, Shanghai Jiao Tong University, Shanghai, 200240, China.

Plant UV-B responses are mediated by the photoreceptor UV RESISTANCE LOCUS 8 (UVR8). In response to UV-B irradiation, UVR8 homodimers dissociate into monomers that bind to the E3 ubiquitin ligase CONSTITUTIVE PHOTOMORPHOGENIC1 (COP1). The interaction of the C27 domain in the C-terminal tail of UVR8 with the WD40 domain of COP1 is critical for UV-B signaling. Read More

Testosterone replacement therapy in insulin-sensitive hypogonadal men restores phosphatidylcholine levels by regulation of arachidonic acid metabolism.

J Cell Mol Med 2020 Jun 3. Epub 2020 Jun 3.

Department of Science and Technology for Agriculture, Forestry, Nature and Energy (DAFNE), University of Tuscia, Viterbo, Italy.

Male hypogonadism is notoriously associated with altered lipid metabolism. In this study, we performed an untargeted mass spectrometry-based profiling of plasma lipids from twenty healthy and twenty hypogonadal men before and after testosterone replacement therapy (TRT) for 60 days. Results demonstrated that hypogonadism was associated with a significant increase in sphingomyelin (SM), whereas phosphatidylcholine (PC) was mainly cleaved by activated phospholipase-A2 into lysophosphatidylcholine (LPC).

Co-catabolism of arginine and succinate drives symbiotic nitrogen fixation.

Mol Syst Biol 2020 Jun;16(6):e9419

Institute of Molecular Systems Biology, Eidgenössische Technische Hochschule (ETH) Zürich, Zürich, Switzerland.

Biological nitrogen fixation emerging from the symbiosis between bacteria and crop plants holds promise to increase the sustainability of agriculture. One of the biggest hurdles for the engineering of nitrogen-fixing organisms is an incomplete knowledge of metabolic interactions between microbe and plant. In contrast to the previously assumed supply of only succinate, we describe here the CATCH-N cycle as a novel metabolic pathway that co-catabolizes plant-provided arginine and succinate to drive the energy-demanding process of symbiotic nitrogen fixation in endosymbiotic rhizobia.
