An Arabidopsis Pentatricopeptide Repeat Is A Moonlighting Protein With Cross-Talking In Vitro Adenylyl Cyclase And Kinase Activities
(Springer, 2023)Downstream signalling involving adenylyl cyclases (ACs) and kinases is a key component of several processes in plants including cell division, growth, and response to stress. ACs are enzymes that generate the second ... -
An Arabidopsis Linker Histone-Like Protein Harbours A Domain With Adenylyl Cyclase Activity
(Springer, 2023)Adenylyl cyclase (AC) is an enzyme that catalyses the formation of the second messenger molecule, 3′,5′-cyclic adenosine monophosphate (cAMP) from 5′-adenosine triphosphate (ATP). cAMP, in turn, regulates key physiological ... -
Using Confocal Microscopy And Pigment Analyses To Detect Adverse Insecticide Effects In Non-Target Freshwater Diatom Species - A Proof-Of-Concept Using Nitzschia Palea
(Springer, 2023)The persistence of insecticides in aquatic environments is a cause of concern and to date hardly any studies have focused on the effects that DDT and deltamethrin have on non-target freshwater diatom communities. The ... -
Tuberculosis Is Associated With Sputum Metabolome Variations, Irrespective Of Patient Sex Or Hiv Status: An Untargeted Gcxgc-Tofms Study
(Springer, 2023)Introduction Various studies have identified TB-induced metabolome variations. However, in most of these studies, a large degree of variation exists between individual patients. Objectives To identify differential ... -
Machine Learning Research Trends In Africa: A 30 Years Overview With Bibliometric Analysis Review
(Springer, 2023)The machine learning (ML) paradigm has gained much popularity today. Its algorithmic models are employed in every feld, such as natural language processing, pattern recognition, object detection, image recognition, earth ... -
Impact Of Herbivory By Zerenopsis Lepida (Lepidoptera: Geometridae) On The Endangered Encephalartos Eugene-Maraisii Under Field Conditions
(Springer, 2023)Encephalartos eugene-maraisii is an endangered, endemic plant in the Waterberg Mountain range of South Africa. This is the first report of herbivory by Zerenopsis lepida (Lepidoptera: Geometridae) on natural populations ... -
A Ketogenic Diet Alters Mtor Activity, Systemic Metabolism And Potentially Prevents Collagen Degradation Associated With Chronic Alcohol Consumption In Mice
(Springer, 2023)Introduction A ketogenic diet (KD), which is a high fat, low carbohydrate diet has been shown to inhibit the mammalian target of rapamycin (mTOR) pathway and alter the redox state. Inhibition of the mTOR complex has been ... -
Count Regression And Machine Learning Techniques For Zero-Inflated Overdispersed Count Data: Application To Ecological Data
(Springer, 2023)The aim of this study is to investigate the overdispersion problem that is rampant in ecological count data. In order to explore this problem, we consider the most commonly used count regression models: the Poisson, the ... -
A Review Of Key Terminology And Definitions Used For Birth Defects Globally
(Springer, 2023)Birth defects, also known as congenital disorders, are a signifcant health issue impacting at least fve million births annually worldwide. For policymakers to mount a relevant healthcare response to care for those afected, ... -
Evaluation Of Bayesil For Automated Annotation Of 1 H Nmr Data Using Limited Sample Volumes: Application To African Elephant Serum
(Springer, 2023)Introduction Technological advancements enabled the analyses of limited sample volumes on 1 H NMR. Manual spectral profiling of the data is, however, complex, and timely. Objective To evaluate the performance of BAYESIL ... -
Histological Characterization Of Wild Cucumber Resistance To Meloidogyne Species
(Springer, 2023)Using nematode resistant varieties is one of efective and environmental sound strategies being adopted in the management of economically important Meloidogyne species. Wild cucumber (Cucumis africanus) has been reported ... -
Phytochemical-Based Evidence Of The Health Benefits Of Bidens Pilosa Extracts And Cytotoxicity
(Springer, 2023)Purpose Bidens pilosa L. is traditionally used as a flavouring agent in foods, in the treatment of diseases, in agriculture as a biopesticide and herbicide, and in the phytoremediation of soils contaminated with heavy ... -
Power Of Shared Success: How Can Sharing Success And Roles Of Others Motivate African Women In Stem?
(Springer, 2023)This study examines the success and role of African women leaders in science, technology, engineering, and mathematics (STEM). In the absence of signifcant research on women’s STEM leadership, the success and roles of ... -
Metapolystoma Ohlerianum N. Sp. (Monogenea: Polystomatidae) From Aglyptodactylus Madagascariensis (Anura: Mantellidae)
(Springer, 2023)Purpose Despite Madagascar’s high amphibian diversity of more than 400 species, only a few polystome species are known from the island. The dissection of frogs from museum collections, together with amphibian and parasite ... -
Electrochemical Detection Of Dopamine Using Green And Chemical Synthesized Cuo/Pani Nanocomposite Modified Electrode
(Springer, 2023)Copper oxide (CuO) nanoparticles were synthesized using the chemical and green method routes and doped with polyaniline (PANI) to form PANI/CuOch and PANI/CuOgr nanocomposite. The microstructural properties of the ... -
Hydrogen Lyman-Alpha Periodicity Behaviour During Various Solar Cycles
(Springer, 2023)The temporal behaviour of various periodicities of hydrogen Lyman-alpha (Ly-α) between 1950 and 2020 have been analysed using Lomb-Scargle and Morlet wavelets spectral analysis techniques. Daily mean values of Ly-α radiance ... -
