Light‑Driven Propulsion of Graphene Aerogels in Microgravity

Advanced Science, EarlyView.
Ultralight graphene aerogels convert laser light into thrust. Parabolic‐flight experiments directly compare their motion in microgravity and at 1 g, revealing order‐of‐magnitude enhancements in distance, velocity, and transient thrust when weight and friction are removed (∼50 times enhancement).

Comparative analysis of primary repair vs resection and anastomosis, with laparostomy, in management of typhoid intestinal perforation: results of a rural hospital in northwestern Benin [PDF]

, 2013
BACKGROUND: The objective is to compare primary repair vs intestinal resection in cases of intestinal typhoid perforations. In addition, we hypothesised the usefulness of laparostomy for the early diagnosis and treatment of complications.

Scalable Engineering of Bio‐Manufactured Extracellular Vesicles for Selective Delivery in Ovarian Cancer Patient‐Derived Models

Advanced Science, EarlyView.
Engineered extracellular vesicles displaying Ephrin‐B2 selectively target Ephrin‐B4–expressing ovarian cancer cells, enabling precise delivery in patient‐derived models. This scalable bio‐manufacturing platform reveals a versatile strategy to exploit Ephrin signaling for highly specific therapeutic payload delivery and motivates exploration of tailored

Jejunal atresia associated with idiopathic ileal perforation

Journal of Indian Association of Pediatric Surgeons, 2008
Jejunoileal atresia is one of the common causes of neonatal intestinal obstruction. Intestinal perforation with meconium peritonitis in the neonatal period, which carries a high mortality rate, is also common.

Implications of Transient Negative Capacitance Effect in Ferroelectric Polarization Dynamics

Advanced Electronic Materials, EarlyView.
Transient voltage artifacts observed during ferroelectric switching are shown to originate from measurement circuitry rather than intrinsic negative capacitance. By correlating switching current, time scale, and series resistance, this work establishes practical design rules for reliable pulse‐switching experiments and circuit integration of ...

Association of intestinal alkaline phosphatase with necrotizing enterocolitis among premature infants [PDF]

, 2019
Importance: Necrotizing enterocolitis (NEC) in preterm infants is an often-fatal gastrointestinal tract emergency. A robust NEC biomarker that is not confounded by sepsis could improve bedside management, lead to lower morbidity and mortality, and permit

Advancing Fruit Bioimpedance Monitoring With Sustainable, Soft, And Bio‐Based Electrodes Beyond ECG

Advanced Electronic Materials, EarlyView.
Electrical impedance spectroscopy enables non‐destructive fruit quality monitoring, but conventional ECG and needle electrodes compromise signal stability, fruit physiology, and sustainability. This perspective highlights the transition toward soft, biocompatible, and biodegradable electrode interfaces based on natural substrates, bio‐derived ...

Pneumoperitoneum without Intestinal Perforation in a Neonate: Case Report and Literature Review

Case Reports in Pediatrics, 2017
Pneumoperitoneum in a preterm neonate usually indicates perforation of the intestine and is considered a surgical emergency. However, there are cases of pneumoperitoneum with no evidence of rupture of the intestine reported in the literature. We report a

First Successful Regeneration of a Structurally Native‐Like Colon Using a Bioabsorbable Polymer Sheet

Annals of Gastroenterological Surgery, EarlyView.
This study demonstrated that a bioabsorbable polymer sheet (BAPS) can regenerate approximately half the circumference of the colon with native‐like structure and function in an experimental setting. As the model involved immediate closure after perforation and did not reproduce peritonitis, caution is required when considering clinical applicability ...
