Ozone and nitric oxide induce cGMP-dependent and independent transcription of defence genes in tobacco
(Wiley, 2009)Here, we analyse the temporal signatures of ozone (O3)-induced hydrogen peroxide (H2O2) and nitric oxide (NO) and the role of the second messenger guanosine 3′,5′-cyclic monophosphate (cGMP) in transcriptional changes ... -
Phenolic content, antioxidant, cytotoxic and antiproliferative effects of fractions of Vigna subterraenea (L.) verdc from Mpumalanga, South Africa
(Elsevier, 2021)Consistent intake of legumes has been correlated with decreased possibility of developing colorectal cancer (CRC) due to the content of some phytochemicals like polyphenols. Bambara groundnut (BGN) is an underutilized ... -
Piperonylic acid alters growth, mineral content accumulation and reactive oxygen species-scavenging capacity in chia seedlings
(Oxford University Press, 2022)p-Coumaric acid synthesis in plants involves the conversion of phenylalanine to trans-cinnamic acid via phenylalanine ammonia-lyase (PAL), which is then hydroxylated at the para-position under the action of trans-cinnamic ... -
Plant antimicrobial peptides (pamps): Features, applications, production, expression and challenges
(MDPI, 2022)The quest for an extraordinary array of defense strategies is imperative to reduce the challenges of microbial attacks on plants and animals. Plant antimicrobial peptides (PAMPs) are a subset of antimicrobial peptides ... -
Post-translational cleavage of recombinantly expressed nitrilase from Rhodococcus rhodochrous J1 yields a stable, active helical form
(Wiley, 2007)Nitrilases convert nitriles to the corresponding carboxylic acids and ammonia. The nitrilase from Rhodococcus rhodochrous J1 is known to be inactive as a dimer but to become active on oligomerization. The recombinant enzyme ... -
The potential of chalcone-capped gold nanoparticles for the management of diabetes mellitus
(Surfaces and Interfaces, 2021-08)Searching for new natural bioactive capping agents represent an urgent priority in the green synthesis of metal nanoparticles. Additionaly, the biosaftey of metal nanparticles is a major concern especially in medical ... -
PR-1-Like Protein as a Potential Target for the Identification of Fusarium oxysporum: An In Silico Approach
(BioTech, 2021-07)Fusarium oxysporum remains one of the leading causes of economic losses and poor crop yields; its detection is strained due to its presentation in various morphological and physiological forms. This research work sought ... -
Predicting haplogroups using a versatile machine learning program (PredYMaLe) on a new mutationally balanced 32 Y-STR multiplex (CombYplex): Unlocking the full potential of the human STR mutation rate spectrum to estimate forensic parameters
(Elsevier, 2020)We developed a new mutationally well-balanced 32 Y-STR multiplex (CombYplex) together with a machine learning (ML) program PredYMaLe to assess the impact of STR mutability on haplogourp prediction, while respecting forensic ... -
Prevalence of hypertension and its associated risk factors in a rural black population of Mthatha town,South Africa
(MPDI, 2021)The occurrence of hypertension has been increasing alarmingly in both low and middle-income countries. Despite acknowledging hypertension as the most common life-threatening risk factor for cardiovascular disease (CVD), a ... -
Prevalence, patterns and determinants of dyslipidaemia among South African adults with comorbidities
(Nature Research, 2022)The present study assessed the prevalence, patterns and determinants of dyslipidaemia among South African adults with multi-morbidities. In this study, 614 individuals with DM and hypertension were recruited. Dyslipidaemia ... -
The production of hydrogen through the use of a 77 wt% Pd 23 wt% Ag membrane water gas shift Reactor
(Elsevier, 2016)Hydrogen as an energy carrier has the potential to decarbonize the energy sector. This work presents the application of a palladium-silver (PdeAg) membrane-based reactor. The membrane reactor which is made from PdeAg film ... -
Progesterone, myo-inositol, dopamine and prolactin present in follicular fluid have differential effects on sperm motility subpopulations
(MDPI, 2021)Considering the challenges surrounding causative factors in male infertility, rather than relying on standard semen analysis, the assessment of sperm subpopulations and functional characteristics essential for fertilization ... -
Prospects of using gum Arabic silver nanoparticles in toothpaste to prevent dental caries
(MDPI, 2023)There is growing interest in the use of green synthesized silver nanoparticles (AgNPs) to control and prevent dental diseases. The incorporation of green synthesized AgNPs into dentifrices to reduce pathogenic oral ... -
Proteomic analysis of grape berry cell cultures reveals that developmentally regulated ripening related processes can be studied using cultured cells
(Public Library of Science, 2011)This work describes a proteomics profiling method, optimized and applied to berry cell suspensions to evaluate organ-specific cultures as a platform to study grape berry ripening. Variations in berry ripening within a ... -
Proteomic identification and meta-analysis in salvia hispanica RNA-seq de novo assemblies
(2021)While proteomics has demonstrated its value for model organisms and for organisms with mature genome sequence annotations, proteomics has been of less value in nonmodel organisms that are unaccompanied by genome sequence ... -
PZQ Therapy: How close are we in the development of effective alternative anti-schistosomal drugs?
(Bentham Science Publishers, 2019)Today schistosomiasis, caused mainly by the three major schistosome species (S. mansoni, S. haematobium and S. japonicum), has for many decades and still continues to be on a rapid and swift rise globally, claiming ... -
Recent advancements in the breeding of sorghum crop: current status and future strategies for marker-assisted breeding
