Therapeutic use and pharmacological safety of herbal medicines
(Elsevier, 2019)In general, N80% of the world's population relies on traditional medicine for their primary healthcare [1]. The use of complementary herbal medicine provides an alternative option to modern allopathic treatment for ... -
The selective targeting of cancer cells by using Pheroid® as a drug delivery system
(Elsevier, 2019)Pheroid® is a drug delivery system with possible use in the treatment of chronic diseases such as cancer and that enhances the efficacy of the treatment of chronic diseases [1]. Current cancer treatment is non-selective, ... -
In vitro determination of the preclinical safety of Pheroid® doxorubicin formulations using patch clamp assays
(Elsevier, 2019)One of the most active, widely used and well-known drugs in breast cancer chemotherapy, doxorubicin (DOX), is an anthracycline ring antibiotic derived from the bacteria Streptomyces peucetius. Its clinical use is however, ... -
Pharmacoepidemiology capacity building in the Latin American and African regions
(Wiley, 2019)Background: An electronic screening survey of pharmacoepidemiology (PE) capacity building was developed for the Latin America (LatAm) and African regions. The objective of the screening survey was to identify a target ... -
Hydrothermal preparation of biochar from spent coffee grounds, and its application for the removal of cadmium from coal tailings leachate
(SAIMM, 2019)Spent coffee grounds were transformed into biochar using a hydrothermal method. Some of the biochar product was pre-treated through surfactant impregnation with sodium dodecyl sulphate (SDS) to enhance its adsorption ... -
DFT + U studies of the electronic and optical properties of ReS2 mono-layer doped with lanthanide atoms
(IOP Publishing, 2019)The structural, electronic and optical properties of various elements in the lanthanide series as dopant atoms in the triclinic mono-layered rhenium disulphide (ReS2) structure was evaluated using density functional theory ... -
Blazar variability -- expect the unexpected
(Sissa Medialab, 2018)Despite significant progress in both data taking and the development of theory, blazars keep offering surprises. While many frequency bands are now covered by long-term monitoring efforts on at least a few selected sources, ... -
The ASTRI dual-mirror small-size Cherenkov telescope
(Sissa Medialab, 2018)The ASTRI dual-mirror small-size telescope (ASTRI-Horn) is an imaging atmospheric Cherenkov telescope that was developed by the Italian National Institute of Astrophysics (INAF) within the framework of the Cherenkov Telescope ... -
Modelling the polarisation signatures detected from the first white dwarf pulsar AR Sco.
(Sissa Medialab, 2018)Marsh et al. (2016) detected radio and optical pulsations from the binary system AR Scorpii (AR Sco). This system, with an orbital period of 3.55 h, is composed of a cool, low-mass star and a white dwarf with a spin period ... -
Simultaneous fitting of the spectral energy density, energy-dependent size, and X-ray spectral index vs. radius of the young pulsar wind nebula PWN G0.9+0.1
(Sissa Medialab, 2018)We have constructed and calibrated a spherically-symmetric, spatially-dependent particle transport and emission code for young pulsar wind nebulae (PWNe). This code predicts the spectral energy distribution (SED) of the ... -
Spectral variability signatures of relativistic shocks in blazars
(Sissa Medialab, 2018)Mildly relativistic, oblique shocks are frequently invoked as possible sites of relativistic particle acceleration and production of strongly variable, polarized multi-wavelength emission from relativistic jet sources ... -
Particle-in-cell simulations of shear boundary layers in relativistic jets
(Sissa Medialab, 2018)The supermassive black holes in the centres of active galaxies (AGN) eject powerful relativistic jets which propagate over kpc scales, showing no significant momentum loss. Both observational evidence as well as theoretical ... -
Exploiting high-energy polarization in blazars
(Sissa Medialab, 2018)The spectral energy distributions (SEDs) and variability of astrophysical sources can be modeled in many different ways, in particular, the production of X-rays and γ-rays in the SEDs of blazars. High-energy polarimetry ... -
An analytical hadronic synchrotron mirror model for blazars: application to 3C279
(Sissa Medialab, 2018)On the 28th of January, the High Energy Stereoscopic System (H.E.S.S. the world’s largest ground-based gamma-ray observatory, located in Namibia) detected an orphan TeV gamma-ray flare in 3C279, not accompanied by flaring ... -
Six new epibiotic Proschkinia (Bacillariophyta) species and new insights into the genus phylogeny
(Taylor & Francis, 2019)The diatom genus Proschkinia is a common element of biofilms covering diverse substrata in saline inland or shallow coastal environments. It can be distinguished from other naviculoid taxa by its lanceolate valves with a ... -
High genetic variation and phylogeographic relations among Palearctic fairy shrimp populations reflect persistence in multiple southern refugia during Pleistocene ice ages and postglacial colonisation
(Wiley, 2019)Intense anthropogenic disturbance threatens temporary pond ecosystems and their associated fauna across the Palearctic. Since fairy shrimps (Crustacea, Branchiopoda) are endemic to temporary ponds, populations are declining ... -
What can a comparative genomics approach tell us about the pathogenicity of mtDNA mutations in human populations?
(Wiley, 2019)Mitochondrial disorders are heterogeneous, showing variable presentation and penetrance. Over the last three decades, our ability to recognize mitochondrial patients and diagnose these mutations, linking genotype to ... -
Extraction of uranium from synthetic nuclear conversion plant waste
(Taylor & Francis, 2019)The nuclear conversion plant operated at Necsa in the past resulted in the formation of a large amount of waste material containing ~ 50% U, which has reuse potential if the recovery thereof can be achieved. The waste ... -
Suitability of wild host plants and firewood as hosts of Prostephanus truncatus (Coleoptera: Bostrichidae) in Mozambique
(Oxford Univ Press, 2019)Prostephanus truncatus (Horn) (Coleoptera: Bostrichidae) populations are maintained in wild host plants such as trees that act as pest reservoirs from where beetle infestation of maize granaries take place. In this study, ... -
New particle formation, growth and apparent shrinkage at a rural background site in western Saudi Arabia
(EGU, 2019)Atmospheric aerosols have significant effects on human health and the climate. A large fraction of these aerosols originates from secondary new particle formation (NPF), where atmospheric vapors form small particles that ...
