Contact Sex Pheromone Activity of Synthetic Gomadalactones in Male White-Spotted Longhorn Beetle, Anoplophora malasiaca (Coleoptera: Cerambycidae).

The elytra of females of the white-spotted longhorn beetle, Anoplophora malasiaca (Coleoptera: Cerambycidae), are coated with a contact sex pheromone, which was previously shown to be composed of at least three chemical groups. Individually, the chemical groups had little pheromonal activity, but a blend of all three exhibited activity equal to that of the crude female extract. Two groups are female-specific aliphatic hydrocarbons and ketones, which were previously synthesized and confirmed to elicit mating behavior.

Validation of Energy and Nutrition Intake in Japanese Elderly Individuals Estimated Based on a Short Food Frequency Questionnaire Compared against a 7-day Dietary Record: The Kyoto-Kameoka Study.

To determine the association between geriatric disorders and dietary intake, validation of a food frequency questionnaire (FFQ) for elderly individuals is needed. We compared energy and nutrient intakes derived from dietary records (DR) and FFQ in an elderly population and compared the data against results from middle-aged individuals (30⁻68 years) from a previous study. Current participants included 65 women and 78 men (65⁻88 years) who completed FFQ and 7-day DR in a subpopulation of the Kyoto-Kameoka study.

Objectives: Bone fractures affect the activities of daily living and lower quality of life, so investigating preventative measures is important. We developed novel stimulation equipment that combined a vibration stimulus with a shaking stimulus for preventing osteoporosis (one of the causes of bone fractures). We aimed to investigate the effect of this equipment on ovariectomized mice.

Pantothenate auxotrophy of Methylobacterium spp. isolated from living plants.

A number of pink-pigmented facultative methylotrophs (PPFMs) belonging to Methylobacterium spp. isolated from living plant samples were found to require B vitamins for their growth in minimal medium, and most B vitamin-auxotrophic PPFMs required pantothenate (vitamin B). Further investigation of pantothenate auxotrophy using the representative strain Methylobacterium sp.

Association between echo intensity and attenuation of skeletal muscle in young and older adults: a comparison between ultrasonography and computed tomography.

Background: Skeletal muscle experiences both quantitative and qualitative changes with aging. Echo intensity (EI) of the skeletal muscle obtained by ultrasonography (US) has been considered to reflect muscle quality. This technique is noninvasive, easily accessible, and is relatively inexpensive than that of other imaging techniques such as computed tomography (CT).

Isolation and Identification of a Volatile Compound in Habanero Pepper (Capsicum chinense).

A volatile compound was isolated from the fruit of Habanero pepper (Capsicum chinense) and related varieties and identified as 6-methyl-(E)-4-heptenyl 3-methylbutyrate by H and C NMR spectroscopy and two-dimensional NMR experiments, including HMQC, HMBC, and H-H COSY. The compound has a retention index of 1387 and is one of the major volatile compounds in Habanero pepper. This compound would be useful as a new flavor.

Association of physical activity with age-related changes in muscle echo intensity in older adults: a 4-year longitudinal study.

Ultrasonic echo intensity (EI), an easy-to-use measure of intramuscular fat and fibrous tissues, is known to increase with aging. However, age-related changes in EI have not been examined in a longitudinal design. The objective of this study was to investigate 4-yr longitudinal changes in the EI of the quadriceps femoris in older adults, based on difference in physical activity (PA).

Arachidonic acid production by the oleaginous fungus 1S-4: A review.

The filamentous fungus 1S-4 is capable of accumulating a large amount of triacylglycerol containing C20 polyunsaturated fatty acids (PUFAs). Indeed, triacylglycerol production by 1S-4 can reach 20 g/L of culture broth, and the critical cellular signaling and structural PUFA arachidonic acid (ARA) comprises 30%-70% of the total fatty acid. The demonstrated health benefits of functional PUFAs have in turn encouraged the search for rich sources of these compounds, including fungal strains showing enhanced production of specific PUFAs.

Validity of a triaxial accelerometer and simplified physical activity record in older adults aged 64-96 years: a doubly labeled water study.

Background: The aim was to examine the validity of a triaxial accelerometer (ACCTRI) and a simplified physical activity record (sPAR) in estimating total energy expenditure (TEE) and physical activity level (PAL) in older adults with the doubly labeled water (DLW) method.

Methods: A total of 44 Japanese elderly individuals (64-96 years), of which 28 were community-dwelling healthy adults with or without sporting habits (S or NS group) and 16 were care home residents with frailty (F group), were included in the study. Basal metabolic rate (BMR) was measured by indirect calorimetry, TEE was obtained by the DLW method, and PAL was calculated as TEE/BMR.

Measuring shared knowledge with group false memory.

We conducted two experiments to investigate the effects of word list consistency and group collaboration on false memory. Using the DRM (Deese-Roediger-McDermott) paradigm, the first experiment (n = 121) examined false memory in a group; participants collaborated to select keywords using a between-subject condition of a consistent or randomized word list. The proportion of false responses was larger than that of error responses, especially for the consistent word list condition (p < 0.

KaiC family proteins integratively control temperature-dependent UV resistance in Methylobacterium extorquens AM1.

KaiC protein is the pivotal component of the circadian clock in cyanobacteria. While KaiC family proteins are well-conserved throughout divergent phylogenetic lineages, studies of the physiological roles of KaiC proteins from other microorganisms have been limited. We examined the role of the KaiC proteins, KaiC1 and KaiC2, in the methanol-utilizing bacterium Methylobacterium extorquens AM1.
