Upper paired domination in graphs

AIMS Mathematics, 2022
A set $ PD\subseteq V(G) $ in a graph $ G $ is a paired dominating set if every vertex $ v\notin PD $ is adjacent to a vertex in $ PD $ and the subgraph induced by $ PD $ contains a perfect matching.

Tailoring Apixaban in Nanostructured Lipid Carrier Enhancing Its Oral Bioavailability and Anticoagulant Activity

Pharmaceutics, 2022
Apixaban (Apx), an oral anticoagulant drug, is a direct factor Xa inhibitor for the prophylaxis against venous thromboembolism. Apx has limited oral bioavailability and poor water solubility.

Truthful approximation mechanisms for restricted combinatorial auctions [PDF]

, 2008
When attempting to design a truthful mechanism for a computationally hard problem such as combinatorial auctions, one is faced with the problem that most efficiently computable heuristics can not be embedded in any truthful mechanism (e.g.

Genome-wide investigation and expression profiling of APX gene family in Gossypium hirsutum provide new insights in redox homeostasis maintenance during different fiber development stages

Zeitschrift für Induktive Abstammungs- und Vererbungslehre, 2018
Ascorbate peroxidase (APX) is a member of heme-containing peroxidases which catalyze the H2O2-dependent oxidation of a wide range of substrates in plants and animals.

S-nitrosylation of SlAPX Is Involved in Alleviating Oxidative Damage in Transgenic Tobacco under Nitrate Stress

Agronomy, 2023
Nitric oxide (NO) modulates plant response by post-translationally modifying proteins, mainly through S-nitrosylation. Ascorbate peroxidase (APX) in the ascorbate-glutathione (AsA-GSH) cycle participates in the removal of hydrogen peroxide (H2O2 ...

Computing graph gonality is hard [PDF]

, 2019
There are several notions of gonality for graphs. The divisorial gonality dgon(G) of a graph G is the smallest degree of a divisor of positive rank in the sense of Baker-Norine.

Impairment of peroxisomal APX and CAT activities increases protection of photosynthesis under oxidative stress

Journal of Experimental Botany, 2018
Proteomics and physiological approaches reveal that peroxisomal APX silencing and CAT inhibition trigger H2O2-signalling for up-regulation of antioxidant proteins to protect the rice photosynthetic apparatus under oxidative stresss.

Adult Sex Ratio as a Demographic Feedback Linking Mating Systems, Parental Care, and Evolution

Advanced Science, EarlyView.
Breeding systems are some of the most diverse social behavior, and our team is investigation the evolutionary causes of this diversity. This review summarises our research carried out at the University of Bath. We argue that demographic components of wild populations, especially the adult sex ratio, plays a key role driving breeding system variation ...

Lacking catalase, a protistan parasite draws on its photosynthetic ancestry to complete an antioxidant repertoire with ascorbate peroxidase

BMC Evolutionary Biology, 2019
Background Antioxidative enzymes contribute to a parasite’s ability to counteract the host’s intracellular killing mechanisms. The facultative intracellular oyster parasite, Perkinsus marinus, a sister taxon to dinoflagellates and apicomplexans, is ...

Atomically Dispersed Cu Nanozyme with Intensive Ascorbate Peroxidase Mimic Activity Capable of Alleviating ROS‐Mediated Oxidation Damage

Advanced Science, 2022
Ascorbate peroxidase (APX) as a crucial antioxidant enzyme has drawn attentions for its utilization in preventing cells from oxidative stress responses by efficiently scavenging H2O2 in plants.
