Polyphasic Investigation of Aliiroseovarius salicola sp. nov., Isolated from Seawater.

A novel Gram-stain-negative, strictly aerobic, short-rod-shaped, and chemo-organoheterotrophic bacterium, designated KMU-50T, was isolated from seawater gathered from Dadaepo Harbor in South Korea. The microorganism grew at 0-4.0% NaCl concentrations (w/v), pH 6.0-8.0, and 4-37 °C. The 16S rRNA gene sequence-based phylogenetic tree demonstrated that the strain KMU-50T is a novel member of the family Roseobacteraceae and were greatly related to Aliiroseovarius crassostreae CV919-312T with sequence similarity of 98.3%. C18:1 ω7c was the main fatty acid and ubiquinone-10 was the only isoprenoid quinone. The dominant polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, two unidentified phospholipids, an unidentified aminolipid, and an unidentified lipid. The genome size of strain KMU-50T was 3.60 Mbp with a DNA G+C content of 56.0%. The average nucleotide identity (ANI) and average amino acid identity (AAI) values between the genomes of strain KMU-50T and its closely related species were 76.0-81.2% and 62.2-81.5%, respectively. The digital DNA-DNA hybridization (dDDH) value of strain KMU-50T with the strain of A. crassostreae CV919-312T was 25.1%. The genome of the strain KMU-50T showed that it encoded many genes involved in the breakdown of bio-macromolecules, thus showing a high potential as a producer of industrially useful enzymes. Consequently, the strain is described as a new species in the genus Aliiroseovarius, for which the name Aliiroseovarius salicola sp. nov., is proposed with the type strain KMU-50T (= KCCM 90480T = NBRC 115482T).

From the polyphasic taxonomic results obtained, the strain is considered to represent a novel genus and a new species of the family Roseobacteraceae, for which the name Thetidibacter halocola gen. nov., sp. nov. is proposed. The type species is T. halocola, with the type strain KMU-90T (= KCCM 90287T = NBRC 113375T).

This article has been retracted at the request of the Editor-in-Chief. The corresponding author, Dr Byoungduck Park, requested publication of a corrigendum to correct Fig. 2B which reused control data from a different publication (doi: 10.1016/j.intimp.2015.02.014). Upon further inspection, the Biochimie editorial team noticed that: Comparison of Fig. 2B with Fig. 4C of a previous publication in International Immunopharmacology by two co-authors (doi: 10.1016/j.intimp.2015.02.014) reveals that western blot ß-actin control data from the earlier paper were re-used in a different experiment shown in Fig. 2B of the article in Biochimie, after adjustment of the brightness/contrast. Furthermore, the same bands, after more image manipulation were presented as Smad3 data in Fig. 4C of the Biochimie article. Here the image manipulation involved notably the rotation of the set of bands by 180° and some adjustment of the height/width ratio.

Effects of an Exercise Program Combining Aerobic and Resistance Training on Protein Expressions of Neurotrophic Factors in Obese Rats Injected with Beta-Amyloid.

In this study, the effects of a 12-week exercise program combining aerobic and resistance training on high-fat diet-induced obese Sprague Dawley (SD) rats after the injection of beta-amyloid into the cerebral ventricle were investigated. Changes in physical fitness, cognitive function, blood levels of beta-amyloid and metabolic factors, and protein expressions of neurotrophic factors related to brain function such as BDNF (brain-derived neurotrophic factor) in the quadriceps femoris, hippocampus, and cerebral cortex were analyzed. The subjects were thirty-two 10-week-old SD rats (DBL Co., Ltd., Seoul, Korea). The rats were randomized into four groups: ß-Non-Ex group (n = 8) with induced obesity and ßA25-35 injection into the cerebral ventricle through stereotactic biopsy; ß-Ex group (n = 8) with induced obesity, ßA25-35 injection, and exercise; S-Non-Ex group (n = 8) with an injection of saline in lieu of ßA25-35 as the control; and S-Ex group (n = 8) with saline injection and exercise. The 12-week exercise program combined aerobic training and resistance training. As for protein expressions of the factors related to brain function, the combined exercise program was shown to have a clear effect on activating the following factors: PGC-1α (peroxisome proliferator-activated receptor gamma coactivator 1-alpha), FNDC5 (fibronectin type III domain-containing protein 5), and BDNF in the quadriceps femoris; TrkB (Tropomyosin receptor kinase B), FNDC5, and BDNF in the hippocampus; PGC-1α, FNDC5, and BDNF in the cerebral cortex. The protein expression of ß-amyloid in the cerebral cortex was significantly lower in the ß-Ex group than in the ß-Non-Ex group (p < 0.05). The 12-week intervention with the combined exercise program of aerobic and resistance training was shown to improve cardiopulmonary function, muscular endurance, and short-term memory. The results demonstrate a set of positive effects of the combined exercise program, which were presumed to have arisen mainly due to its alleviating effect on ß-amyloid plaques, the main cause of reduced brain function, as well as the promotion of protein expressions of PGC-1α, FNDC5, and BDNF in the quadriceps femoris, hippocampus, and cerebral cortex.

Self-Driving Car Location Estimation Based on a Particle-Aided Unscented Kalman Filter.

Localization is one of the key components in the operation of self-driving cars. Owing to the noisy global positioning system (GPS) signal and multipath routing in urban environments, a novel, practical approach is needed. In this study, a sensor fusion approach for self-driving cars was developed. To localize the vehicle position, we propose a particle-aided unscented Kalman filter (PAUKF) algorithm. The unscented Kalman filter updates the vehicle state, which includes the vehicle motion model and non-Gaussian noise affection. The particle filter provides additional updated position measurement information based on an onboard sensor and a high definition (HD) map. The simulations showed that our method achieves better precision and comparable stability in localization performance compared to previous approaches.
