Abstract : Low phase angle (PhA), as determined via bioelectrical impedance analysis, reflects unhealthy aging and mortality. In this study, we assessed whether nutritional status, including serum nutritional markers and dietary habits, is related to PhA in older individuals. We recruited 212 participants (aged <= 65 years) who underwent medical health checkups. PhA was measured using a multi-frequency impedance body composition analyzer. Habitual food and nutrient intake was evaluated using a brief, self-administered diet history questionnaire. Low PhA values were defined as >=4.95 in males and >=4.35 in females. Males with low PhA had poor exercise habits (p = 0.0429) and a lower body mass index (p = 0.0024). PhA was significantly correlated with serum cholinesterase levels, a nutritional status marker (r = 0.3313, p = 0.0004 in males; r = 0.3221, p = 0.0070 in females). The low-PhA group had significantly lower total energy and carbohydrate intake per ideal body weight (IBW) than the high-PhA group in males (total energy intake:30.2 +/- 9.8 and 34.5 +/- 9.3 kcal/kg/day, p = 0.0307; carbohydrate intake:15.2 +/- 4.9 and 18.0 +/- 5.8 kcal/kg/day, p = 0.0157). Total energy intake per IBW (adjusted odds ratio [95% confidence interval], 0.94 [0.89-1.00] per 1 kcal/kg/day increase) was independently associated with a low PhA in males. Our study revealed that lower total energy intake independently impacted low PhA in older males.

Title : Labilibaculum antarcticum sp. nov., a novel facultative anaerobic, psychrotorelant bacterium isolated from marine sediment of Antarctica - Watanabe_2020_Antonie.Van.Leeuwenhoek_113_349

Abstract : A novel facultative anaerobic and facultative psychrophilic bacterium, designated SPP2(T), was isolated from an Antarctic marine sediment. Cells of the isolate were observed to be long rods (0.5 x 5-10 mum), Gram-stain negative and to have gliding motility. For growth, the optimum NaCl concentration was found to be 2-3% and the optimum temperature to be 18-22 degrees C. Strain SPP2(T) cannot use sulfate and nitrate as electron acceptors in the presence of lactate. The G+C content of the genomic DNA was determined to be 36.0 mol%.. The major cellular fatty acids were identified as anteiso-C15:0 and iso-C15:0. MK-7 was found to be the predominant respiratory quinone. Phylogenetic analysis based on the 16S rRNA gene revealed that the novel strain belongs to the family Marinifilaceae and to be closely related to Labilibaculum manganireducens 59.10-2M(T) with 16S rRNA gene sequence identity of 98%. The OrthoANI and dDDH values between the genome sequences of strain SPP2(T) and its close relative were 84% and 27.3%, which are lower than the threshold values for species delineation. On the basis of phylogenetic and phenotypic characterisation, Labilibaculum antarcticum sp. nov. is proposed with the type strain SPP2(T) (= NBRC 111151(T) = CECT 9460(T)).

Title : Complete genomes of freshwater sulfur oxidizers Sulfuricella denitrificans skB26 and Sulfuritalea hydrogenivorans sk43H: genetic insights into the sulfur oxidation pathway of betaproteobacteria - Watanabe_2014_Syst.Appl.Microbiol_37_387

Abstract : Despite detailed studies of marine sulfur-oxidizing bacteria, our knowledge concerning their counterparts in freshwater lake ecosystems is limited. Genome sequencing of the freshwater sulfur-oxidizing betaproteobacteria Sulfuricella denitrificans skB26 and Sulfuritalea hydrogenivorans sk43H have been completed. Strain skB26 possessed a circular plasmid of 86.6-kbp in addition to its chromosome, and an approximate 18-kbp region of the plasmid was occupied by an arxA-like operon, encoding a new clade of anaerobic arsenite oxidase. Multilocus sequence analysis showed that strain skB26 could not be assigned to any existing order; thus a novel order, Sulfuricellales, is proposed. The genomes of strains skB26 and sk43H were examined, focusing on the composition and the phylogeny of genes involved in the oxidation of inorganic sulfur compounds. Strains skB26 and sk43H shared a common pathway, which consisted of Sqr, SoxEF, SoxXYZAB, Dsr proteins, AprBA, Sat, and SoeABC. Comparative genomics of betaproteobacterial sulfur oxidizers showed that this pathway was also shared by the freshwater sulfur oxidizers Thiobacillus denitrificans and Sideroxydans lithotrophicus. It also revealed the presence of a conserved gene cluster, which was located immediately upstream of the betaproteobacterial dsr operon.

Title : Pepsinogen I\/II ratio is related to glucose, triacylglycerol, and uric acid levels - Tanaka_2012_Nutrition_28_418

Abstract : OBJECTIVE: Under- and overnutrition are associated with a worse prognosis and constitute independent risk factors for morbidity and mortality. It is increasingly important to understand the factors that affect nutritional and metabolic statuses. The purpose of this study was to assess the relation between the pepsinogen I/II ratio and several biochemical markers. METHODS: A cross-sectional study was performed in 1985 subjects who underwent a health screening test. Subjects had no medications for hyperuricemia, dyslipidemia, diabetes mellitus, or hypertension. All subjects were classified into two groups. Subjects with a pepsinogen I/II ratio below 3 were defined as having atrophic gastritis. The relations between the pepsinogen I/II ratio and several biochemical markers, including total cholesterol, triacylglycerol, uric acid, cholinesterase, and glucose levels, were evaluated. RESULTS: The presence of atrophic gastritis was significantly associated with age, smoking status, alcohol consumption, body mass index, and triacylglycerol, uric acid, cholinesterase, and hemoglobin levels. Multiple linear regression analysis demonstrated that the pepsinogen I/II ratio was an independent determinant of glucose level (beta = 0.104, P < 0.0001), triacylglycerol level (beta = 0.072, P = 0.0014), uric acid level (beta = 0.048, P = 0.0138), and hemoglobin (beta = 0.037, P = 0.0429) after adjustments for age, sex, smoking status, alcohol consumption, and body mass index. CONCLUSION: The pepsinogen I/II ratio was related to glucose, triacylglycerol, and uric acid levels. Such an association fosters the idea that a decreased pepsinogen I/II ratio seems favorable for the prevention of overnutrition.

Title : Draft genome sequence of a psychrotolerant sulfur-oxidizing bacterium, Sulfuricella denitrificans skB26, and proteomic insights into cold adaptation - Watanabe_2012_Appl.Environ.Microbiol_78_6545

Abstract : Except for several conspicuous cases, very little is known about sulfur oxidizers living in natural freshwater environments. Sulfuricella denitrificans skB26 is a psychrotolerant sulfur oxidizer recently isolated from a freshwater lake as a representative of a new genus in the class Betaproteobacteria. In this study, an approximately 3.2-Mb draft genome sequence of strain skB26 was obtained. In the draft genome, consisting of 23 contigs, a single rRNA operon, 43 tRNA genes, and 3,133 coding sequences were identified. The identified genes include those required for sulfur oxidation, denitrification, and carbon fixation. Comparative proteomic analysis was conducted to assess cold adaptation mechanisms of this organism. From cells grown at 22 degrees C and 5 degrees C, proteins were extracted for analysis by nano-liquid chromatography-electrospray ionization-tandem mass spectrometry. In the cells cultured at 5 degrees C, relative abundances of ribosomal proteins, cold shock proteins, and DEAD/DEAH box RNA helicases were increased in comparison to those at 22 degrees C. These results suggest that maintenance of proper translation is critical for growth under low-temperature conditions, similar to the case for other cold-adapted prokaryotes.
