This research determines improved flight-path routes that make maximum utilization of terrain-masking opportunities, and defending radar and missile system equipment performance and launch timing constraints, in order to...

In this work, we evaluated the effects of cadmium (Cd) on the antioxidant defense system responses and the role of nitrate reductase (NR) in the redox balance maintenance in Bradyrhizobium japonicum strains. For that, B....

The integration of unmanned aerial systems (UAS) into the already complex global aviation system presents new and unique hazards. While many studies have addressed the potential safety concerns of UAS integration, little...

Current knowledge of the nervous system, particularly the brain, is the result of technological advances and the collective effort of many scientists. However, it was Santiago Ramón y Cajal (1852–1934) who played a cr...

Recent studies suggest that territorial defense can act as a regulating agent of herbivore density, buffering crowding effects and preventing vegetation depletion. The occurrence of territorial families and non-territori...

ABSTRACT The Hna phage defense system is one of many systems that protect bacteria against bacterial viruses (phages). Hna was first discovered in the nitrogen-fixing alphaproteobacterium Sinorhizobium meliloti, which fo...

Postoperative atrial fibrillation (AF) is the most common arrhythmia following cardiac surgery with extracorporeal circulation. The pathogenesis of postoperative AF is multifactorial. Oxidative stress, caused by the unav...

Security is a central theme in international relations and modern political science, particularly given the evolving security landscape in Europe and globally. Traditional mechanisms for maintaining stability, such as th...

Looking at the global rules for maintaining world peace, everyone believed that the years after 1989 would be characterized by peace and diversification of trade relations between sovereign countries, since the Cold War,...

Abstract Rhizome rot, caused by Pythium myriotylum (P. myriotylum), is a significant constraint on ginger cultivation, necessitating the development of sustainable defense strategies. The present study, therefore, evalua...

The military aggression of the Russian Federation against Ukraine, through the use of the full range of enemy aerial attack means not only against military targets but also against critical infrastructure objects (herein...

Abstract The lymnaeids are important in the epidemiology of Fasciola hepatica, a neglected and endemic zoonosis. The interaction between the internal defense system of Pseudosuccinea columella and F. hepatica has been li...

Background and Aim: Cryopreservation of boar semen is widely used for genetic conservation and artificial insemination; however, it induces oxidative stress and molecular alterations that compromise sperm function. Epige...

Background: As humans are gifted by a defense system, Plants also possess a specialized system of defense that helps them to combat attacking microorganisms and harsh environmental conditions. This defense system is in t...

El presente trabajo tiene por objetivo analizar los posicionamientos de los Estados miembro de la Unión de Naciones Suramericanas (Unasur) frente al proceso de reforma de los instrumentos hemisféricos de defensa —esp...

Background. The significant increase in the number of patients with arterial hypertension both worldwide and in our country necessitates a more detailed study of the pathogenetic features of changes that occur in target ...

Abstract Soil salinity poses a major constraint and a primary threat to global food security, demanding sustainable strategies to maintain crop productivity on marginal lands. This study evaluated the role of exogenous m...

Oxidative stress is one of the proposed mechanisms to explain renal function impairment in chronic renal failure (CRF). There is growing evidence supporting that oxidative balance is disturbed due to either overproductio...
