Cribrilina mutabilisn. sp., an Eelgrass-Associated Bryozoan (Gymnolaemata: Cheilostomata) with Large Variationin Zooid Morphology Related to Life History
We describe the cribrimorph cheilostome bryozoan Cribrilina mutabilis n. sp., which we detected as an epibiont on eelgrass (Zostera marina) at Akkeshi, Hokkaido, northern Japan. This species shows three distinct zooid types during summer: the R (rib), I (intermediate), and S (shield) types. Evidence indicates that zooids commit to development as a given type, rather than transform from one type to another with age. Differences in the frontal spinocyst among the types appear to be mediated by a simple developmental mechanism, acceleration or retardation in the production of lateral costal fusions as the costae elongate during ontogeny. Colonies of all three types were identical, or nearly so, in partial nucleotide sequences of the mitochondrial COI gene (555–631 bp), suggesting that they represent a single species. Zooid types varied temporally in overall frequency in the population: colonies contained nearly exclusively R-type zooids in mid-June; predominantly I-type, or both R- and I-type, zooids in mid-July; and I-type, S-type, or both I- and S-type zooids (interspersed or in discrete bands) in mid- to late August. Reproduction occurred throughout the season, but peaked in July, with only R- and I-type zooids reproducing. Reproductive zooids bear a vestigial compound (tripartite) ooecium and brood internally; S-type zooids, first appearing in August, were non-reproductive, which suggests that they may serve as an overwintering stage. As this species is easily accessible, common, and simple in form, it is potentially useful as a model system for studying polyphenism at multiple levels (zooid, colony, and population) in the context of life-history adaptations
Competitive Adsorption on Graphite Investigated Using Frequency-Modulation Atomic Force Microscopy: Interfacial Liquid Structure Controlled by the Competition of Adsorbed Species
The
competitive adsorption of long-chain (C<sub>18</sub> and C<sub>24</sub>) carboxylic acids versus <i>n</i>-decanol on graphite
was investigated using frequency-modulation atomic force microscopy.
A long-range-ordered monolayer of the solute (stearic acid or lignoceric
acid) developed in saturated decanol solution, whereas an ordered
decanol monolayer was deposited from dilute solutions. The piconewton-order
tip–surface force was observed in solutions as a function of
the vertical and lateral coordinates, together with the topography
of the monolayers. The tip–surface force was periodically modulated,
which was interpreted with a solution structure commensurate with
the ordered assembly of adsorbed monolayers. These results show that
the solution structure at the interface was controlled by the competitively
adsorbed species and thus was sensitive to the composition of the
bulk solution
Cribrilina mutabilisn. sp., an Eelgrass-Associated Bryozoan (Gymnolaemata: Cheilostomata) with Large Variationin Zooid Morphology Related to Life History
Cross-Sectional Structure of Liquid 1‑Decanol over Graphite
The interface of graphite and liquid 1-decanol was studied
using
frequency modulation atomic force microscopy (FM-AFM). The topography
of epitaxially physisorbed decanol on the substrate was traced with
submolecular resolution. The tip–surface force was monitored
in the liquid as a function of the vertical and lateral tip coordinates
to reveal the cross-sectional structure of the interfacial decanol.
Four or more liquid layers were identified by vertically modulated
force distributions. The first and second liquid layers were laterally
heterogeneous, as evidenced by a force distribution that was periodically
modulated along lateral coordinates. A possible structuring mechanism
is proposed on the basis of energy gain by hydrogen bonding and van
der Waals interactions

Screening dataset of food components that enhance transcriptional activity of PGC1-beta
PGC-1β is a transcriptional co-activator of nuclear receptors, which acts to increase energy expenditure. PGC-1β fused to GAL4 DNA-binding domain transfected in HEK293T cells showed a reporter luciferase activity. We screened food-derived and natural compounds using a reporter assay system to measure the transcriptional activity of PGC-1β.We found that soy-derived isoflavones, genistein and daidzein, and several resveratrols activated PGC-1β, see “Genistein, daidzein, and resveratrols stimulate PGC-1β-mediated gene expression” [1]. The list of 166 compounds and their reporter activity is shown here. Keywords: Screening, Reporter assay, Transcriptional activit
Association of serum adiponectin and myostatin levels with skeletal muscle in patients with obesity: A cross-sectional study.
BackgroundAdiponectin has been reported to be associated with lower skeletal muscle mass and skeletal strength and may be involved in skeletal muscle regulation along with myostatin. This study aims to evaluate the association between serum adiponectin and myostatin levels and identify independent factors using body composition and metabolic parameters in patients with obesity.MethodsOverall, 148 patients (age, 45.9 ± 14.3 years, body mass index, 37.2 ± 8.0 kg/m2) who initially visited the outpatient clinic of obesity between November 2013 and November 2019 were included. Body composition was measured using InBody 720 and dual energy X-ray absorptiometry. In addition, muscle strength, vascular function, and metabolic parameters were measured. Serum levels of adiponectin, leptin, myostatin, and irisin were measured from blood samples.ResultsThe serum adiponectin level was 2.9 μg/mL (1.7-4.1 μg/mL), and the serum myostatin level was 2398.4 pg/mL (1,777.1-2952.5 pg/mL). The stepwise regression analysis revealed less leg strength, homeostasis model assessment of insulin resistance, and C-reactive protein as an independent predictor of serum adiponectin levels based on the significance of the univariate analysis (R2 = 0.190, P ConclusionThe serum adiponectin level was associated with less muscle strength. Although serum myostatin was associated with a high appendicular lean mass, it is possible that myostatin was regulated by the percentage of body weight from appendicular lean mass
