Genetic Influences of the Microbiota on the Life Span of Drosophila melanogaster.

To better understand how associated microorganisms ("microbiota") influence organismal aging, we focused on the model organism We conducted a metagenome-wide association (MGWA) as a screen to identify bacterial genes associated with variation in the life span. The results of the MGWA predicted that bacterial cysteine and methionine metabolism genes influence fruit fly longevity. A mutant analysis, in which flies were inoculated with strains bearing mutations in various methionine cycle genes, confirmed a role for some methionine cycle genes in extending or shortening fruit fly life span.

The microbiota influences the Drosophila melanogaster life history strategy.

Organisms are locally adapted when members of a population have a fitness advantage in one location relative to conspecifics in other geographies. For example, across latitudinal gradients, some organisms may trade off between traits that maximize fitness components in one, but not both, of somatic maintenance or reproductive output. Latitudinal gradients in life history strategies are traditionally attributed to environmental selection on an animal's genotype, without any consideration of the possible impact of associated microorganisms ("microbiota") on life history traits.

Draft Genome Sequence of DmW181, a Bacterium Isolated from Wild .

The draft genome sequence of DmW181, an anaerobic bacterium isolate from wild flies, is reported here. Strain DmW181 possesses genes for sialic acid and mannose metabolism. The assembled genome is 3,201,429 bp, with 3,454 predicted genes.

Genome Sequence of DmW_103, Isolated from Wild .

Lactic acid bacteria are commonly associated with spp. Here, we report on the isolation of a strain of and the sequencing, assembly, and annotation of its genome. A total of 35 contigs were generated, with 2,349 coding sequences found.

Genome Sequence of DmW_111, Isolated from Wild .

Isolates of the lactic acid bacterium are a major part of fermentation processes, especially in Korean kimchi. Here, we present the genome of DmW_111, isolated from wild ; analysis of this genome will expand the diversity of genome sequences for non- spp. isolated from .

Fibromyalgia syndrome: considerations for dental hygienists.

Fibromyalgia syndrome (FMS) is a neurosensory disorder characterized by widespread musculoskeletal pain. Typically persistent fatigue, depression, limb stiffness, non-refreshing sleep and cognitive deficiencies are also experienced. Oral symptoms and pain are common, requiring adaptations in patient management strategies and treatment interventions.

The effect of food label cues on perceptions of quality and purchase intentions among high-involvement consumers with varying levels of nutrition knowledge.

Objective: To determine whether differences in nutrition knowledge affected how women (a high-involvement group) interpreted intrinsic cues (ingredient list) and extrinsic cues ("all natural" label) on food labels.

Methods: A 2 (intrinsic cue) × 2 (extrinsic cue) × 2 (nutrition knowledge expert vs novice) within-subject factorial design was used. Participants were 106 female college students (61 experts, 45 novices).
