Objective: The effect of experimental manipulations of the thin beauty ideal, as portrayed in the mass media, on female body image was evaluated using meta-analysis.
Method: Data from 25 studies (43 effect sizes) were used to examine the main effect of mass media images of the slender ideal, as well as the moderating effects of pre-existing body image problems, the age of the participants, the number of stimulus presentations, and the type of research design.
Results: Body image was significantly more negative after viewing thin media images than after viewing images of either average size models, plus size models, or inanimate objects. This effect was stronger for between-subjects designs, participants less than 19 years of age, and for participants who are vulnerable to activation of a thinness schema.
Conclusion: Results support the sociocultural perspective that mass media promulgate a slender ideal that elicits body dissatisfaction. Implications for prevention and research on social comparison processes are considered.

Anti-mullerian hormone (AMH) detection receives much attention since it is used as an ideal biomarker for quantitative assessment of ovarian reserve. The present study proposed a first report on the use of MOF-on-MOF as an electrochemical sensor for recognizing AMH in buffer and serum media. The MOF-on-MOF, MIL-88 B@UiO66NH was synthesized by the internal extended growth method (IEGM) involving MIL-88 B on UiO66NH by in situ method for the first time.

The challenge of "false positive" signals significantly complicates tumor localization and surgical resection, which are pivotal for successful tumor surgeries. Therefore, the development of a method for preoperative tumor localization and intraoperative margin determination holds considerable promise for improving surgical outcomes. In this study, a zero-crosstalk ratiometric tumor-targeting near-infrared (NIR) fluorescent probe was developed for precise cancer diagnosis and intraoperative navigation via NIR fluorescence imaging.

Following myocardial infarction (MI), the accumulation of CD86-positive macrophages in the ischemic injury zone leads to secondary myocardial damage. Precise pharmacological intervention targeting this process remains challenging. This study engineered a nanotherapeutic delivery system with CD86-positive macrophage-specific targeting and ultrasound-responsive release capabilities.

This is a maximal intensity projection of CA1 pyramidal cell transfected with plasmid with the reporter GFP using single cell electroporation technique. In this particular case the organotypic slices were prepared from p5-7 pups in a tissue chopper (McIlwain). And maintained in MEM bases media with added glutamax with a change in 2 alternative dyas at 37°C and 5% CO for 4 days in-vitro (DIV) before electroporating with a glass pipette of 7-10mΩ resistance by applying 4 square pulses of -ve voltage of -2.
