Conditions for the formation of anomalous tail of comet

Open Astronomy, 2019
The time and velocity of ejection of dust particles of anomalous tails from cometary nuclei are determined. It is revealed that some comets cause the formation of an anomalous tail is the collision of their comet nucleus with other bodies of the Solar ...

Polymerase iota (POLI) confers radioresistance of esophageal squamous cell carcinoma by regulating RAD51 stability and facilitating homologous recombination

Cell Death Discovery, 2023
Radiotherapy resistance is an important and urgent challenge in the clinical management of esophageal squamous carcinoma (ESCC). However, the factors mediating the ESCC resistance to radiotherapy and its underlying molecular mechanisms are not fully ...

Lung Ultrasound for the Detection of Radiologic Progression of Interstitial Lung Abnormalities in Patients With Rheumatoid Arthritis

Arthritis &Rheumatology, EarlyView.
Objective Interstitial lung disease (ILD) is an important extra‐articular manifestation of rheumatoid arthritis (RA) associated with high mortality and morbidity. Lung ultrasonography (LUS) has recently emerged as a possible screening tool. We assessed the role of LUS in monitoring radiologic progression and the development of new interstitial lung ...

On the mechanism of formation of anomalous comet tails

Open Astronomy
The objective of the study is to investigate the directions of potential collisions between meteoroids and comets. To this end, the inclinations of 99 comet orbits with anomalous tails were calculated in relation to 112 established meteoroid stream ...

Oocyte–cumulus cell interaction: a key factor in early embryo development

Biological Reviews, EarlyView.
ABSTRACT The evaluation of oocyte competence is a fundamental step in achieving successful outcomes following assisted reproduction techniques (ART). At present, however, conventional oocyte maturation assessment is carried out by morphological observation, which is a subjective method that does not consider molecular features.

Progress report on new epilepsy treatments: A summary of the Eighteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XVIII). I. Treatments in preclinical and early clinical development

Epilepsia, EarlyView.
Abstract Over the last 34 years, the Eilat Conference on New Antiepileptic Drugs and Devices has provided an interactive forum for stakeholders to discuss investigational and recently licensed treatments for seizures and epilepsy. The Eighteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XVIII) took place in Madrid, Spain, on May 3 ...

Evaluation of DNA/Chromosome Integrity and Cell Death in Human Metabolically Noncompetent and Competent Cells Exposed to N′‐(3,5‐Difluorobenzylidene)Pyridine‐4‐Carbohydrazide

Journal of Applied Toxicology, EarlyView.
ABSTRACT The N‐acylhydrazone scaffold is recognized as a privileged structure for the design of bioactive substances with increasing applications in medicinal chemistry research. Ensuring the safety of newly developed molecules is a critical step for both human health and environmental protection. Accordingly, this study aimed to evaluate the cytotoxic

Single‐egg comet assay: A protocol to quantify DNA damage in natural bioarchives

Methods in Ecology and Evolution
The comet assay (CA), originally developed as toxicity test, quantifies DNA integrity from DNA distribution across an electric field. Compromised DNA moves across electric fields faster than intact DNA strands, leaving quantifiable signatures that ...
