Small‐Scale Magnetic Peristaltic Soft Robot With Mobility and Transport Capabilities

Advanced Intelligent Systems, EarlyView.
This study introduces a miniature, untethered soft magnetic microrobot with peristaltic capabilities for both locomotion and cargo transport. Eight helically magnetized elastomeric strips deform under rotating fields (10–80 mT, 1–5 Hz), enabling movement across rods and lumina at up to 4.1 body lengths min‐¹.

Peristalsis prevents ureteral dilation

Neurourology and Urodynamics, 2023
AbstractPurposeThe etiology of ureteral dilation in primary nonrefluxing, nonobstructing megaureters is still not well understood. Impaired ureteral peristalsis has been theorized as one of the contributing factors. However, ureteral peristalsis and its “normal” function is not well defined. In this study, using mathematical modeling techniques, we aim

Gut Health in Ostriches (Struthio camelus): Insights Into Intestinal Structure, Functions, Microbiome, and Improvement Strategies

Animal Research and One Health, EarlyView.
Our paper systematically reviews the intestinal structure, function, and microbiota of ostriches, along with strategies for improving their gut health. We analyze how these factors collectively influence intestinal homeostasis and ostrich welfare, emphasizing probiotics as a promising intervention to enhance gut health, boost population well‐being, and

Efeito do tratamento da depressão sobre o esvaziamento gástrico Treatment of depression effect on the gastric emptying

Brazilian Journal of Psychiatry, 1999
O esvaziamento gástrico foi medido por meio de refeição sólida marcada com 99mTc em 11 pacientes que atendiam os critérios de "depressão maior" do DSM-III-R antes e após o tratamento com fluoxetina (20 a 40mg por dia) durante nove semanas.

A Practical Gut‐On‐Chip Workflow for Imaging‐Based Assessment of Epithelial Barrier Dynamics During E. coli Co‐Culture

Biotechnology and Bioengineering, EarlyView.
ABSTRACT The intestinal epithelium and its resident microbiota form a dynamic interface that is central to gut homeostasis, but this interface is difficult to model with conventional tools. Static Transwell cultures lack physiological fluid shear, whereas animal models are costly and poorly suited to quantitative, high‐content imaging.

Eudragit®‐engineered pH‐responsive probiotic microspheres with enhanced gastrointestinal resistance and prolonged storage stability for inflammatory bowel disease therapy

BMEMat, EarlyView.
This study reports the development of AMS@Eud core‐shell microspheres, combining calcium alginate and pH‐responsive Eudragit® L100, which exhibit exceptional gastrointestinal resistance and long‐term storage stability (only 5.28%–9.09% viability loss over 35 days at 4–25°C), and effectively alleviate inflammatory bowel disease via gut microbiota ...

Indocyanine green for intraoperative ureteral identification in gynecologic surgery: A preliminary systematic review of feasibility, safety, and surgical outcomes

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Intraoperative ureteral injury, although uncommon, can result in significant morbidity and medicolegal consequences, particularly during complex gynecologic procedures such as endometriosis excision and prolapse repair. Conventional ureteral identification techniques, including stents and methylene blue, have recognized limitations.

Hypervision Proton Surgery: The Future Direction of Proton Therapy

iNew Medicine, EarlyView.
ABSTRACT Proton beams provide unique physical advantages characterized by a low entrance dose, negligible exit dose, and a sharp Bragg peak, which enable superior sparing of normal tissues and support safe dose escalation for improved tumor control. However, conventional photon‐based fractionation remains widely used in proton therapy, where prolonged ...

Incidental Detection of Portal Venous Gas During POCUS in a Neonate With Necrotizing Enterocolitis and Intestinal Perforation: A Case Report

Journal of Clinical Ultrasound, EarlyView.
Point‐of‐care ultrasound performed at the bedside identified hepatic portal venous gas in a critically ill neonate, prompting urgent evaluation and revealing intestinal perforation due to necrotizing enterocolitis. This case highlights the potential of POCUS to accelerate diagnosis when clinical signs are subtle or nonspecific.
