Cancer is a complex disease whereby multiple genetic aberrations, epigenetic modifications, metabolic reprogramming, and the microenvironment contribute to the development of a tumor. In the traditional anticancer drug discovery pipeline, drug candidates are usually screened in vitro using two-dimensional or three-dimensional cell culture. However, these methods fail to accurately mimic the human disease state. This has led to the poor success rate of anticancer drugs in the preclinical stages since ...

Due to the poor conductivity of metal-organic frameworks (MOFs), it is challenging to directly employ MOFs as electrode materials for supercapacitors. Herein, hydroxyl-functionalized multi-walled carbon nanotube (f-MWCNT) was used to decorate ZnO/C obtained from the prior calcination of pristine zeolitic imidazolate framework-8 (ZIF-8) and applied as electrode material for supercapacitor application. The resulting ZnO/[email protected] electrode exhibits excellent storage performance, as confirmed ...

Adult medical male circumcision (MC) is safe: global notifiable adverse event (AE) rates average below 2.0%. With Zimbabwe's shortage of health care workers (HCWs) compounded by COVID-19 constraints, two-way text-based (2wT) MC follow-up may be advantageous over routinely scheduled in-person reviews. A 2019 randomized control trial (RCT) found 2wT to be safe and efficient for MC follow-up. As few digital health interventions successfully transition from RCT to scale, we detail the 2wT scale-up approach ...

Abstract Background Voluntary medical male circumcision (VMMC) is an HIV prevention strategy recommended to partially protect men from heterosexually acquired HIV. From 2015 to 2019, the President’s Emergency Plan for AIDS Relief (PEPFAR) has supported approximately 14.9 million VMMCs in 15 African countries. Urethrocutaneous fistulas, abnormal openings between the urethra and penile skin through which urine can escape, are rare, severe adverse events (AEs) that can occur with VMMC.

Abstract A modified homogeneous precipitation method has been used to synthesize ZnS nanoparticles. Starch and polyvinyl alcohol (PVA) were utilized as capping molecules, and later, the ZnS–PVA-capped nanoparticles were then incorporated with chitosan to form ZnS–chitosan nanocomposites for the removal of Cr( vi ) ion from wastewater. The optical measurements of the synthesized ZnS nanoparticles showed the band gap which was blue-shifted when compared with the bulk ZnS material. The crystalline structures ...

Metal-organic frameworks (MOFs)-derived nanomaterials have emerged as novel electrodes for electrochemical energy storage application. Herein, MOF-derived NiO and NiO/Ni composite electrodes have been successfully synthesized by a unique double-linker MOF-strategy involving a series of calcination procedures (400 °C, 500 °C and 600 °C). The introduction of calcination temperature influenced both the textural and electrochemical properties of the MOF-derived NiO/Ni-400 and NiO/Ni-500 composite electrodes ...

The hydrogenation of CO2 to methanol was performed over Ga2O3 and ZrO2 modified Cu-Zn based catalysts. The prepared catalysts were characterised via P-XRD, ICP-OES, BET, SEM-EDX, H2-TPR, CO2-TPD, H2-TPD and H2-chemisorption. The focus of this investigation was to assess the role of Ga2O3 and ZrO2 promoters on improving the methanol productivity over the Cu-Zn based catalysts. Emphasis was placed on the differences in CO2 and H2 adsorption capacity and strength due to the introduction of the modifiers, ...

N-doped porous carbon nanotubes (NCNs-A) were successfully prepared by a scalable and straightforward mixed salts (NaCl/ZnCl2) activation method with carbon precursor of polypyrrole (PPy). The independent salt NaCl or ZnCl2, the dosage of mixed salts, and the carbonization temperature all have a strong effect on the final products. ZnCl2 is the key activator for activation, and with an increase of the mixed salts, the surface area of NCNs-A is increased. However, excess salt can lead to a decrease ...

Abstract Background Male circumcision confers partial protection against heterosexual HIV acquisition among men. The President’s Emergency Plan for AIDS Relief (PEPFAR) has supported > 18,900,000 voluntary medical male circumcisions (VMMC). Glans injuries (GIs) are rare but devastating adverse events (AEs) that can occur during circumcision. To address this issue, PEPFAR has supported multiple interventions in the areas of surveillance, policy, education, training, supply chain, and AE management. Methods ...

Membrane separation processes tender a capable option for energy-demanding separation processes. Nanofiltration (NF) and reverse osmosis (RO) membranes are among the most explored, with a latent use in the chemical industry. In this study, four commercial membranes (NF90, NF270, BW30, and XLE) were investigated for their applicability based on the key structural performance characteristics in the recycling of Pd-based catalysts from Heck coupling post-reaction mixture. Pure water and organic solvent ...

Carbon from black cumin seeds was modified with 10 and 20% sulfuric acid to obtain the activated adsorbents. Pristine carbon from black cumin seeds, 10 and 20% H2SO4 activated carbon from black cumin seeds were labelled CBC, ACBC-10 and ACBC-20, respectively. The adsorbents were characterized by SEM, XRD, FTIR, TGA and BET. The adsorbents maximum trend for Cd(II) was ACBC-10 > ACBC-20 > CBC. The maximum capacity trend for methylene blue dye was ACBC-20 > ACBC-10 > CBC. The kinetic model best fitted pseudo ...

Objective Although adverse events (AEs) following voluntary medical male circumcision (VMMC) are rare, their prompt ascertainment and management is a marker of quality care. The use of two-way text messaging (2wT) for client follow-up after VMMC reduces the need for clinic visits (standard of care (SoC)) without compromising safety. We compared the cost-effectiveness of 2wT to SoC for post-VMMC follow-up in two, high-volume, public VMMC sites in Zimbabwe. Materials and methods We developed a decision- ...

Few studies that reported on black cumin seeds (BS) showed that the material has good adsorption capacity towards metal ions. Therefore, it is fair to conduct further studies on the material. However, literature survey shows that no previous study on black cumin seeds has reported on the effect of phosphoric acid (H3PO4) and potassium permanganate (KMnO4) activating agents on the removal of toxic cadmium Cd(II) and chromium Cr(VI) ions from aqueous solution. Pristine black seeds were designated (PBS), ...

Background Voluntary medical male circumcision (MC) is safe and effective. Nevertheless, MC programs require multiple post-operative visits. In Zimbabwe, a randomized control trial (RCT) found that post-operative two-way texting (2wT) between clients and MC providers instead of in-person reviews reduced provider workload and safeguarded patient safety. A critical component of the RCT assessed usability and acceptability of 2wT among providers and clients. These findings inform scale-up of the 2wT approach ...

To circumvent the limited availability of RNA extraction reagents, we aimed to develop a protocol for direct RT-qPCR to detect SARS-CoV-2 in nasopharyngeal swabs without RNA extraction. Nasopharyngeal specimens positive for SARS-CoV-2 and other coronaviruses collected in universal viral transport (UVT) medium were pre-processed by several commercial and laboratory-developed methods and tested by RT-qPCR assays without RNA extraction using different RT-qPCR master mixes. The results were compared ...

Carbon dioxide (CO2) is considered a useful greenhouse gas that can be captured and be used in the electro-syntheses of useful chemicals or fuels. On the other hand, there’s also a tremendous interest on ethanol beneficiation as it is largely produced from crops, and it is regarded as a potential candidate for low temperature fuel cell applications. Although ethanol possesses good advantages, its resistant to oxidation poses a threat. The main objective of the study is to synthesis bio-inspired metal ...

Ensuring quality service provision is fundamental to ZAZIC's voluntary medical male circumcision (MC) program in Zimbabwe. From October, 2014 to September, 2017, ZAZIC conducted 205,847 MCs. Passive surveillance recorded a combined moderate and severe adverse event (AE) rate of 0.3%; reported adherence to follow-up was 95%, suggesting program safety. Despite encouraging passive surveillance data, verification of data quality and accuracy would increase confidence in AE identification.From May to August, ...
