Intact HIV proviruses persist in children seven to nine years after initiation of antiretroviral therapy in the first year of life
(American Society for Microbiology, 2020)In adults starting antiretroviral therapy (ART) during acute infection, 2% of proviruses that persist on ART are genetically intact by sequence analysis. In contrast, a recent report in children treated early failed to ... -
An integrated and comparative approach towards identification, characterization and functional annotation of candidate genes for drought tolerance in sorghum (Sorghum bicolor (L.) Moench)
(BioMed Central, 2017)BACKGROUND: Drought is the most disastrous abiotic stress that severely affects agricultural productivity worldwide. Understanding the biological basis of drought-regulated traits, requires identification and an in-depth ... -
An integrated approach of reservoir characterization of Y gas feld in central Bredasdorp Basin, South Africa
(Springer, 2022)The study attempts to address the knowledge gap in the Bredasdorp Basin Ofshore South Africa by using newly acquired seismic data with an enhanced resolution, integrating core and well log to provide a solution. The main ... -
Integrating RADAR and optical imagery improve the modelling of carbon stocks in a mopane-dominated African savannah dry forest
(Wiley, 2022-12-25)This study examined the integration of two satellite data sets, that is Landsat 7 ETM+ and ALOS PALSAR (Advanced Land Observing Satellite Phased Array type L-band Synthetic Aperture RADAR) in estimating carbon stocks in ... -
Integration of hydrogeophysical and geological investigations in enhancing groundwater potential assessment in Houtriver gneiss crystalline basement formation of South Africa
(Elsevier, 2021)Groundwater exploration in crystalline basement aquifers such as the Houtriver gneiss formation in the Limpopo province of South Africa is often described as complex. This is because groundwater availability in such aquifers ... -
Intellectual laziness and academic dishonesty: A threat to academic freedom?
(South African Assn. For The Advancement Of Science, 2020)Academic freedom freedom matters; it matters a great deal. It is a sine qua non for the the success of our science system . When scientists scientists invoke academic academic freedom whenever they they are are expected ... -
Intelligent transportation related complex systems and sensors
(MPDI, 2021)Building around innovative services related to different modes of transport and traffic management, intelligent transport systems (ITSs) are being widely adopted worldwide to improve the efficiency and safety of the ... -
Inter-Seasonal Estimation of Grass Water Content Indicators Using Multisource Remotely Sensed Data Metrics and the Cloud-Computing Google Earth Engine Platform
(MDPI, 2023)Indicators of grass water content (GWC) have a significant impact on eco-hydrological processes such as evapotranspiration and rainfall interception. Several site-specific factors such as seasonal precipitation, temperature, ... -
Interacting dark energy from redshift-space galaxy clustering
(IOP Publishing, 2021)Interacting dark energy models have been proposed as attractive alternatives to CDM. Forthcoming Stage-IV galaxy clustering surveys will constrain these models, but they require accurate modelling of the galaxy power ... -
Interaction analysis of statistically enriched mutations identified in Cameroon recombinant subtype CRF02_AG that can influence the development of Dolutegravir drug resistance mutations
(BMC, 2021)The Integrase (IN) strand transfer inhibitor (INSTI), Dolutegravir (DTG), has been given the green light to form part of first-line combination antiretroviral therapy (cART) by the World Health Organization (WHO). ... -
Intercolony variation in reproductive skipping in the African penguin
(Wiley Open Access, 2022)In long-lived species, reproductive skipping is a common strategy whereby sexually mature animals skip a breeding season, potentially reducing population growth. This may be an adaptive decision to protect survival, or ... -
Intercomparison of the representations of the atmospheric chemistry of pre-industrial methane and ozone in earth system and other global chemistry-transport models
(Elsevier, 2021)An intercomparison has been set up to study the representation of the atmospheric chemistry of the pre-industrial troposphere in earth system and other global tropospheric chemistry-transport models. The intercomparison ... -
An interesting case of carbamazepine-induced Stevens–Johnson Syndrome
(Springer, 2018)A 29-year-old Black female patient was admitted to a psychiatric ward with symptoms of major depressive disorder with psychosis. The patient was started on amitriptyline 50 mg/day and haloperidol 10 mg/day. On day 4 ... -
Interferometric H I intensity mapping: perturbation theory predictions and foreground removal effects
(Oxford University Press, 2023)We provide perturbation theory predictions for the H I intensity mapping power spectrum multipoles using the Effective Field Theory of Large Scale Structure, which should allow us to exploit mildly non-linear scales. ... -
International Glossina Genome Initiative 2004-2014: a driver for post-genomic era research on the African continent
(PLOS, 2014)Human African trypanosomiasis (HAT), also known as sleeping sickness, is a neglected disease that impacts 70 million people distributed over 1.55 million km2 in sub- Saharan Africa and includes at least 50% of the population ... -
International nonproprietary names for monoclonal antibodies: an evolving nomenclature system
(Taylor and Francis, 2022)Appropriate nomenclature for all pharmaceutical substances is important for clinical development, licensing, prescribing, pharmacovigilance, and identification of counterfeits. Nonproprietary names that are unique and ... -
An Internet paradigm approach to policy-based network management of legacy kit for VoIP services in Next Generation Networks
(Telkom, 2000)With QoS available on IP-dominant NGNs, Policy-based Network Management (PBNM) is an effective mechanism for managing services as opposed to actual devices. IP is ubiquitous, and any NGN must contend with legacy devices ... -
