Crater Observing Bioinspired Rolling Articulator (COBRA)

Advanced Intelligent Systems, EarlyView.
Crater Observing Bio‐inspired Rolling Articulator (COBRA) is a modular, snake‐inspired robot that addresses the mobility challenges of extraterrestrial exploration sites such as Shackleton Crater. Incorporating snake‐like gaits and tumbling locomotion, COBRA navigates both uneven surfaces and steep crater walls.

Skeletal pathologies in extant crocodilians as a window into the paleopathology of fossil archosaurs

The Anatomical Record, EarlyView.
Abstract Crocodilians, together with birds, are the only extant relatives to many extinct archosaur groups, making them highly important for interpreting paleopathological conditions in a phylogenetic disease bracketing model. Despite this, comprehensive data on osteopathologies in crocodilians remain scarce.

Solar Wind Interactions with Comet C/2021 A1 Using STEREO HI and a Data-assimilative Solar Wind Model

The Astrophysical Journal
Cometary tails display dynamic behavior attributed to interactions with solar wind structures. Consequently, comet-tail observations can serve as in situ solar wind monitors.

Defining minimum image quality criteria for common diagnostic point‐of‐care ultrasound images: A position statement of the Society of Hospital Medicine

Journal of Hospital Medicine, EarlyView.
Abstract Background Point‐of‐care ultrasound (POCUS) use continues to expand across multiple clinical subspecialties, and the need for standardization of training and quality assurance has become increasingly important. Despite the need for training, there are currently no widely accepted multispecialty criteria to define an acceptable quality POCUS ...

A Systematic Mapping Review of Core Outcome Reporting in Surgical Research for Oesophageal Cancer

Journal of Surgical Oncology, EarlyView.
ABSTRACT Oesophageal carcinoma is a rising global health burden, with surgical resection and perioperative chemotherapy forming the cornerstone of curative treatment. However, uncertainty persists regarding the optimal surgical approach, partly due to heterogeneity in outcome reporting, which hinders data synthesis and evidence‐based decision‐making ...

Detection of Hypoxia in Human Brain Tumor Xenografts Using a Modified Comet Assay

Neoplasia: An International Journal for Oncology Research, 2003
We used the standard comet assay successfully to generate in vitro dose-response curves under oxic and hypoxic conditions. We then made mixtures of cells that had been irradiated with 3 and 9 Gy of X-rays to simulate two subpopulations in a tumor, but ...

HMGB1 Assists in Overcoming Cisplatin Resistance in Chemoresistant Human Ovarian Cancer Cells

Molecular Carcinogenesis, EarlyView.
ABSTRACT Cisplatin is one of the most effective chemotherapeutic agents used in the treatment of ovarian cancer. However, the frequent development of cisplatin resistance remains a significant limitation, leading to therapeutic failure and poor patient outcomes.

Pulmonary scan in evaluating alveolar-interstitial syndrome in ER

Emergency Care Journal, 2006
Diffuse comet-tail artifacts at lung ultrasound are due to thickened interlobular septa and extravascular lung water. This condition is typical of the alveolar-interstitial syndrome due to pulmonary edema, diffuse parenchymal lung disease or ARDS. Aim of

Reactive lymphoid hyperplasia of the liver: A case report featuring characteristic nodular and perinodular enhancement

Radiology Case Reports
A 53-year-old female with primary biliary cholangitis was referred for the evaluation of a hepatic nodule identified during routine imaging. Ultrasonography revealed a homogeneous, hypoechoic, 18 mm nodule in segment 3 of the liver. On dynamic CT and MRI,
