Comparison Between Different DNA and Conventional

open access: yesمجله كليه طب الكندي, 2012
Background: The discriminative power of the classical WHO parameters in relation to male fertility is quite low, because they only address few aspects of sperm quality and function.

Arid1a Deficiency Drives Aristolochic Acid‐Induced Liver Tumorigenesis through Ctnnb1 Mutation and Defective Nucleotide Excision Repair

open access: yesAdvanced Science, EarlyView.
ARID1A is frequently mutated in both non‐malignant tissues and cancers, but its role in tumor development after exposure to genotoxic carcinogen remains unclear. It is found that aristolochic acid I accelerated liver tumorigenesis in ARID1A‐deficient context by impairing nucleotide excision repair and enhancing carcinogen bioactivation, revealing key ...

Crater Observing Bioinspired Rolling Articulator (COBRA)

open access: yesAdvanced 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.

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

open access: yesThe 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.

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

open access: yesThe 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.

Transferability and Reproducibility of the HepaRG CometChip Assay

open access: yesEnvironmental and Molecular Mutagenesis, EarlyView.
ABSTRACT This interlaboratory evaluation of HepaRG CometChip was conducted to assess transferability and reproducibility of this new approach methodology (NAM) across four laboratories. Concentrations inducing up to ~70% relative cytotoxicity were determined by the organizing laboratory, and frozen chemical formulation blocks were sent to each ...

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

open access: yesNeoplasia: 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 ...

Acute Toxicity and Genotoxicity of cMoL, a Lectin From Moringa oleifera Seeds With Antifungal Activity Against Cryptococcus Strains

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Coagulant Moringa oleifera lectin (cMoL) is one of the compounds involved in the application of M. oleifera seeds for traditional water treatment methods. The present study highlights the new biotechnological potential of cMoL lectin as an antifungal agent against Cryptococcus neoformans B3501 and H99 and Cryptococcus gattii R265 strains ...

Pulmonary scan in evaluating alveolar-interstitial syndrome in ER

open access: yesEmergency 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
