Lipid Pattern

Recent studies have implicated synucleins in several reactions during the biosynthesis of lipids and fatty acids in addition to their recognised role in membrane lipid binding and synaptic functions. These are among aspects of decreased synuclein functions that are still poorly acknowledged especially in regard to pathogenesis in Parkinson’s disease. Here, we aimed to add to existing knowledge of synuclein deficiency (i.e., the lack of all three family members), with respect to changes in fatty acids and lipids in plasma, liver, and two brain regions in triple synuclein-knockout (TKO) mice. We describe changes of long-chain polyunsaturated fatty acids (LCPUFA) and palmitic acid in liver and plasma, reduced triacylglycerol (TAG) accumulation in liver and non-esterified fatty acids in plasma of synuclein free mice. In midbrain, we observed counterbalanced changes in the relative concentrations of phosphatidylcholine (PC) and cerebrosides (CER). We also recorded a notable reduction in ethanolamine plasmalogens in the midbrain of synuclein free mice, which is an important finding since the abnormal ether lipid metabolism usually associated with neurological disorders. In summary, our data demonstrates that synuclein deficiency results in alterations of the PUFA synthesis, storage lipid accumulation in the liver, and the reduction of plasmalogens and CER, those polar lipids which are principal compounds of lipid rafts in many tissues. An ablation of all three synuclein family members causes more profound changes in lipid metabolism than changes previously shown to be associated with γ-synuclein deficiency alone. Possible mechanisms by which synuclein deficiency may govern the reported modifications of lipid metabolism in TKO mice are proposed and discussed.

Lipid Pattern

A Gram-stain-positive, spore-forming, rod-shaped, motile, strictly aerobic bacterium, designated CAU 1183T, was isolated from marine sand and its taxonomic position was investigated by using a polyphasic approach. The bacterium grew optimally at 30 °C, at pH 8.5 and in the presence of 2 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain CAU 1183T formed a distinct lineage within the genus Oceanobacillus and exhibited the highest similarity to Oceanobacillus chungangensis CAU 1051T (97.6 %). The strain contained MK-7 as the predominant isoprenoid quinone and anteiso-C15 : 0 was the major cellular fatty acid. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The polar lipid pattern of strain CAU 1183T consisted of diphosphatidylglycerol, phosphatidylglycerol and unidentified lipids, including two phospholipids, two glycolipids, a phosphoglycolipid and two lipids. The G+C content of the genomic DNA was 37.5 mol%. On the basis of phenotypic, chemotaxonomic and phylogenetic data, strain CAU 1183T should be assigned to a novel species in the genus Oceanobacillus, for which the name Oceanobacillus arenosus sp. nov. is proposed. The type strain is CAU 1183T ( = KCTC 33037T = CECT 8560T).

Slightly Halophilic Bacterium

A novel Gram-stain-negative, slightly halophilic bacterium, designated strain GASx41T, was isolated from soil of the coastal–marine wetland Gomishan in Iran. Cells of strain GASx41T were curved, ring-like or horseshoe-shaped rods and non-motile. Strain GASx41T was strictly aerobic, and catalase- and oxidase-positive. The strain was able to grow at NaCl concentrations of 1–10 % (w/v), with optimum growth occurring at 2.5–3 % (w/v) NaCl. The optimum temperature and pH for growth were 25–30 °C and pH 7.5–8.0. On the basis of 16S rRNA gene sequence analysis, strain GASx41T was shown to belong to the genus Cyclobacterium within the phylum Bacteroidetes and showed closest phylogenetic similarity to ‘Cyclobacterium jeungdonense’ HMD3055 (98.0 %). The DNA G+C content of strain GASx41T was 48.1 mol%. The major cellular fatty acids of strain GASx41T were iso-C15 : 0, summed feature 4 (iso-C15 : 0 2-OH and/or C16 : 1ω7c), anteiso-C15 : 0 2-OH, anteiso-C15 : 0 and iso-C17 : 0 3-OH, and its polar lipid pattern consisted of phosphatidylethanolamine, phosphatidylcholine and 12 unknown lipids. The only quinone present was menaquinone 7 (MK-7). All these features confirmed the placement of isolate GASx41T within the genus Cyclobacterium . On the basis of evidence from this study, a novel species of the genus Cyclobacterium , Cyclobacterium halophilum sp. nov., is proposed, with strain GASx41T ( = IBRC-M 10761T = CECT 8341T) as the type strain.

Aim. To determine the features and main problems of statin therapy, as well as assess the possibility of achieving the target level of lipid pattern in patients with high and very high cardiovascular risk (CVR) in real clinical practice.Material and methods. The design of the “PRIORITET” observational program is an open observational study. Patients with high and very high CVR were divided into 3 groups in accordance with the initial data: (1) not taking statins, (2) taking statins, but not reaching the target low-density lipoprotein cholesterol (LDL-C) level, (3) taking statins with the achievement of the target LDL-C level, which is justified in replacing the statin inside the class — adverse effects (AE), high price, etc. Within 12 weeks 3 visits of patients to hospitals were carried out: baseline visit (B0), visit 1 month after the study initiation (B1) and visit 3 months after the study initiation (B3). The choice of atorvastatin or rosuvastatin was assessed by the doctors.Results. Groups 1, 2 and 3 included 112, 170 and 16 people, respectively. At B0, 145 (48,7%) patients were prescribed atorvastatin, and 153 (51,3%) — rosuvastatin. Three people dropped out of the study to B3, 295 patients completed the program. Lipid pattern of 285 patients were analyzed: 121 (41%) people (101 with very high CVR and 20 with high CVR) achieved the target LDL-C level, the remaining 164 (59%) patients (CVR — 156 and 8, respectively) — no. The most pronounced dynamics of LDL=C level was revealed in group 1, the differences between group 1 and groups 2 and 3 are highly statistically significant (p<0,0001). There were no differences in the frequency of reaching the target LDL-C level between patients taking atorvastatin or rosuvastatin. The target level of LDL-C (p=0,003) in the treatment of rosuvastatin in patients with high CVR was reached significantly more often than in patients with very high CVR. Also 3 non-serious AEs were reported. On average, in 9% of cases, reaching the target level of LDL-С during visits B1 and B3 was wrong interpreted by the attending physicians.Conclusion. The main problems of statin therapy in real clinical practice are the wrong interpretation of reaching the target level of LDL-C, inertness of doctors in titrating of statins doses and achieving the target level of lipid pattern. It may be the cause of reduced efficiency and deterioration of lipid-lowering therapy results in patients with high and very high CVR. The results of the “PRIORITET” study demonstrated the possibility of improving the practice of statins use and its accordance with clinical guidelines.Skibitsky V.

Lipid Pattern

A non-motile and non-endospore-forming rod, strain NBRC 16403T, was isolated from the phyllosphere of a sedge (Carex sp.). 16S rRNA gene sequence analysis indicated that strain NBRC 16403T was closely related to Herbiconiux solani DSM 19813T (98.6 % 16S rRNA gene sequence similarity), Herbiconiux ginsengi wged11T (97.8 %) and Herbiconiux moechotypicola RB-62T (97.8 %). The peptidoglycan (B2γ type) contained d- and l-2,4-diaminobutyric acids, d-alanine, glycine and threo-3-hydroxyglutamic acid, which replaced glutamic acid almost completely. The predominant menaquinones were MK-10 and MK-11. The polar lipid pattern comprised diphosphatidylglycerol, phosphatidylglycerol, three glycolipids and minor amounts of other polar lipids. The major fatty acids were anteiso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0; no cyclohexyl-C17 : 0 was detected. The DNA G+C content was 71.0 mol%. The results of phylogenetic and DNA–DNA relatedness studies, along with phenotypic differences between strain NBRC 16403T and recognized members of the genus Herbiconiux, indicated that the isolate should be assigned to a novel species of the genus Herbiconiux, for which the name Herbiconiux flava sp. nov. is proposed. The type strain is NBRC 16403T ( = VKM Ac-2058T).

Abstract 1. A yellow-brown component of commercial oil red O separated by our technic of paper chromatography is shown to stain human serum proteins, particularly those that are coagulated by heat. The patterns of serum electropherograms obtained by coloring with the crude oil red O solution consist of a red lipid pattern superimposed on a brownish protein pattern. 2. A method is described for partial removal of the nonred components from the crude oil red O. Satisfactory coloration of lipoproteins was obtained with the "purified" oil red O. 3. It is demonstrated that areas of paper strip covered with protein may stain lighter with some oil red O fractions than the background filter paper.

Lipid Pattern

A novel halophilic bacterium, designated strain MSS4T, was isolated from the solar salterns of Mesolongi, Greece. The micro-organism, a motile, Gram-stain-positive, aerobic rod, proliferated at salinities of 1.0–4.0 M NaCl, with optimal growth at 2.5 M NaCl. Endospores were not observed. Strain MSS4T showed optimal growth at 37 °C and pH 8.0. The G+C content of its DNA was 47.2 mol%. The polar lipid pattern of strain MSS4T consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidic acid and phosphatidylethanolamine. It possessed anteiso-C15 : 0, C18 : 0, C16 : 0 and anteiso-C17 : 0 as the major fatty acids (altogether representing 84.7 % of the total). The predominant isoprenoid quinone was MK-7. The cell-wall peptidoglycan contained meso-diaminopimelic acid. 16S rRNA gene sequence analysis showed that the new isolate has 96.1 % similarity to Bacillus qingdaonensis CM1T and Bacillus aidingensis 17-5T, 95.5 % to Bacillus salarius BH169T and lower similarity to other Bacillus species. These results justify the assignment of strain MSS4T to a novel species within the genus Bacillus, for which the name Bacillus halochares sp. nov. is proposed. The type strain is MSS4T (=LMG 24571T =DSM 21373T).
