Soft Pneumatic Muscles: Revolutionizing Human Assistive Devices with Geometric Design and Intelligent Control.

Soft robotics, a recent advancement in robotics systems, distinguishes itself by utilizing soft and flexible materials like silicon rubber, prioritizing safety during human interaction, and excelling in handling complex or delicate objects. Soft pneumatic actuators, a prevalent type of soft robot, are the focus of this paper. A new geometrical parameter for soft artificial pneumatic muscles is introduced, enabling the prediction of actuation behavior using analytical models based on specific design parameters.

Correlation of body mass index to Ghrelin and IGF-1 among children with short stature.

Objective: To assess the BMI among children with Growth Hormone Deficiency (GHD) and Idiopathic Short Stature (ISS) and its correlation to ghrelin, Growth Hormone (GH), and Insulin-like Growth Factor-1 (IGF-1) levels.

Methods: A cross-sectional descriptive study in which 42 patients attending the Pediatric endocrine clinic were enrolled, allocated into two groups: group I: GHD children; group II: ISS children. Ghrelin, IGF-1 and GH in both groups were measured.

Metabolic effects of antiangiogenic drugs in tumors: therapeutic implications.

Antiangiogenic therapy has become a mainstay of cancer therapeutics, but clinical responses are generally short-term owing to the development of secondary resistance. Tumor starvation by antiangiogenic drugs is largely attributed to increased hypoxia and impaired nutrients supply, suggesting that angiogenesis inhibition causes remarkable metabolic perturbations in the tumor microenvironment. We review here recent acquisitions concerning metabolic effects of angiogenesis blockade in tumors and discuss the possibility that some metabolic features of tumor cells - i.

Evaluation of urinary proepithelin as a potential biomarker for bladder cancer detection and prognosis in Egyptian patients.

Background/aim: Proepithelin is a growth factor that may play a critical role in bladder cancer. Its over-expression in urine of bladder cancer patients gave us the impetus to evaluate its potential suitability as a biomarker for bladder cancer diagnosis and/or prognosis.

Methods: proepithelin was estimated in 86 voided urine samples, including 59 bladder cancer patients and 27 healthy volunteers using quantitative sandwich enzyme immunoassay technique.
