In this theoretical review paper, we provide a developmental-sociocultural framework for the role of social media (SM) in adolescent girls' body image concerns, and in turn, depressive symptoms and disordered eating. We propose that the features of SM (e.g., idealized images of peers, quantifiable feedback) intersect with adolescent developmental factors (e.g., salience of peer relationships) and sociocultural gender socialization processes (e.g., societal over-emphasis on girls' and women's physical appearance) to create the "perfect storm" for exacerbating girls' body image concerns. We argue that, ultimately, body image concerns may be a key mechanism underlying associations between adolescent girls' SM use and mental health. In the context of proposing this framework, we provide empirical evidence for how SM may increase adolescent girls' body image concerns through heightening their focus on (1) other people's physical appearance (e.g., through exposure to idealized images of peers, celebrities, and SM influencers; quantifiable indicators of approval); and (2) their own appearance (e.g., through appearance-related SM consciousness; exposure to idealized self-images; encouraging over-valuing of appearance; and peer approval of photos/videos). Our framework highlights new avenues for future research on adolescent girls' SM use and mental health, which recognize the central role of body image.

Rationale And Objectives: Photon Counting CT (PCCT) offers advanced imaging capabilities with potential for substantial radiation dose reduction; however, achieving this without compromising image quality remains a challenge due to increased noise at lower doses. This study aims to evaluate the effectiveness of a deep learning (DL)-based denoising algorithm in maintaining diagnostic image quality in whole-body PCCT imaging at reduced radiation levels, using real intraindividual cadaveric scans.
Materials And Methods: Twenty-four cadaveric human bodies underwent whole-body CT scans on a PCCT scanner (NAEOTOM Alpha, Siemens Healthineers) at four different dose levels (100%, 50%, 25%, and 10% mAs).

An animal's body mass is said to be indirectly related to its rate of heat loss; that is, smaller animals with higher surface area to volume tend to lose heat faster than larger animals. Thus, thermoregulation should be related to body size, however, generalizable patterns are still unclear. Domestic dogs are a diverse species of endothermic mammals, including a 44-fold difference in body size.

Background: Most patients with chest wall deformities have a negative body image, which affects their self-esteem and quality of life (QoL).
Objectives: The aim of this study was to evaluate changes in patients' QoL after minimally invasive repair of pectus excavatum (MIRPE).
Material And Methods: A prospective, single-center study was conducted between 2019 and 2023.

The human body is an intricate system, where diverse and complex signaling among different organs sustains physiological activities. The eye, as a primary organ for information acquisition, not only plays a crucial role in visual perception but also, as increasing evidence suggests, exerts a broad influence on the entire body through complex circuits upon receiving light signals which is called non-image-forming vision. However, the extent and mechanisms of light's impact on the body through the eyes remain insufficiently explored.

Methods to image the human RPE directly are limited, as it is only about 10 µm thick and situated between the photoreceptor outer segments and Bruch's membrane (BM).
