    Article Snippet: Ciliates of the class Prostomatea show a broad spectrum of feeding strategies and often occur abundantly in various aquatic habitats, playing a vital role in the biogeochemical cycle.. Due to their small cell size and simple structure, prostomateans were considered to be a group with a lower degree of morphological differentiation for a long time.. However, recent research suggests that the diversity of this group of ciliates is higher than previously thought.

    MyBiosource Biotechnology enzyme-linked immunosorbent assay kit (intra-assay coefficient of variation (cv) < 10%, inter-assay cv < 12%)
    Serum calsarcin-2 concentration was negatively associated with skeletal muscle mass index in mice and humans. Eight-week-old C57BL/6J male mice were fed an HFD or chow diet for 24 weeks. The serum calsarcin-2 (CS2) concentrations were determined by enzyme-linked <t>immunosorbent</t> assay, and the total mass of bilateral gastrocnemius muscle mass was measured. The relationship between serum CS2 concentration and skeletal muscle mass per body weight (%) was analyzed using a linear regression analysis. The black dots in the figure represent the assay values for each individual mouse ( A ). A total of seventy-six human subjects were enrolled. The CS2 concentrations were determined by enzyme-linked immunosorbent assay, and the appendicular skeletal muscle mass index (ASMI) was determined by limb skeletal muscle mass (kg)/height 2 (m 2 ). The relationship between serum CS2 concentration and ASMI was analyzed using a linear regression analysis. The black dots in the figure represent the assay values for each individual human ( B ).

Phalloidin (stains actin) appears in blue. AR appears in green. Scale is 0.25 µm·pixel -1 for all images. White scale bar represents 50 µm. Data were analysed using two-tailed, paired t-tests and two-way ANOVA. Values are represented mean ± SD. **indicates p<0.01.

    Treatment with 100 nM testosterone did not significantly change the expression of A) Akt, B) p-Akt, C) mTOR, D) p-mTOR or E) p-MAPK compared to a vehicle control across 1, 4 or 7 days of differentiation. Black circles represent vehicle control condition (CON), white circles represent testosterone treated (TT) condition. Data were analysed via two-way, repeated measures ANOVA.

    Serum calsarcin-2 concentration was negatively associated with skeletal muscle mass index in mice and humans. Eight-week-old C57BL/6J male mice were fed an HFD or chow diet for 24 weeks. The serum calsarcin-2 (CS2) concentrations were determined by enzyme-linked immunosorbent assay, and the total mass of bilateral gastrocnemius muscle mass was measured. The relationship between serum CS2 concentration and skeletal muscle mass per body weight (%) was analyzed using a linear regression analysis. The black dots in the figure represent the assay values for each individual mouse ( A ). A total of seventy-six human subjects were enrolled. The CS2 concentrations were determined by enzyme-linked immunosorbent assay, and the appendicular skeletal muscle mass index (ASMI) was determined by limb skeletal muscle mass (kg)/height 2 (m 2 ). The relationship between serum CS2 concentration and ASMI was analyzed using a linear regression analysis. The black dots in the figure represent the assay values for each individual human ( B ).
