Introduction In recent years, more emphasis has been placed on improving the health-related quality of life (HRQOL) in children with spina bifida (SB). Chronic disability is understood to impact various aspects of the person's life, family, and social functioning, in addition to the specific needs of the disease. The HRQOL is done to assess the patient's quality of life (QOL) in various domains including physical and mental.

A chemo-drug such as cisplatin is effective for cancer treatment but remains non-specific, is susceptible to drug resistance, and induces several side effects on organ systems. Zeolitic imidazolate framework-8, a type of MOF, has gained attention, including as a drug delivery method for targeted cancer therapeutics. In this study, ZIF-8/Silica nanocomposite was synthesized using a one-pot hydrothermal technique using the Stober technique.

In this work, bismuth oxychloride (BiOCl) and Sn-doped BiOCl (SBCl) with improved visible light photocatalytic activity were synthesized via the co-precipitation method. The XRD analysis determined the tetragonal phase of BiOCl, 1 %, 5 %, and 10 % SBCl. The crystallite sizes were in the range of 20-34 nm.

Background: Ward rounds are a cornerstone in the educational experience of junior doctors and an essential part of teaching patient care. Here, we aimed to assess the doctors' perception of ward rounds as an educational opportunity and to identify the obstacles faced in conducting a proper ward round in Sudanese hospitals.

Method: A cross-sectional study was conducted from the 15 to the 30 of January 2022 among house officers, medical officers, and registrars in about 50 teaching and referral hospitals in Sudan.

An iron-based SBA-16 mesoporous silica (ferrisilicate) with a large surface area and three-dimensional (3D) pores is explored as a potential insulin delivery vehicle with improved encapsulation and loading efficiency. Fe was incorporated into a framework of ferrisilicate using the isomorphous substitution technique for direct synthesis. Fe species were identified using diffuse reflectance spectroscopy.

In nanotherapeutics, gaining insight about the drug interaction with the pore architecture and surface functional groups of nanocarriers is crucial to aid in the development of targeted drug delivery. Manganese ferrite impregnated graphene oxide (MnFeO/GO) with a two-dimensional sheet and spherical silica with a three-dimensional interconnected porous structure (MnFeO/silica) were evaluated for cisplatin release and cytotoxic effects. Characterization studies revealed the presence of Mn species with a variable spinel cubic phase and superparamagnetic effect.

Nanoparticles prepared from bio-reduction agents are of keen interest to researchers around the globe due to their ability to mitigate the harmful effects of chemicals. In this regard, the present study aims to synthesize copper oxide nanoparticles (CuO NPs) by utilizing root extracts of ginger and garlic as reducing agents, followed by the characterization and evaluation of their antimicrobial properties against multiple drug resistant (MDR) . In this study, UV-vis spectroscopy revealed a reduced degree of absorption with an increase in the extract amount present in CuO.

Article Synopsis
  • The study presents a new nanocomposite (Fe/S-16/ZIF-8) that combines biocompatible metal-organic frameworks (MOFs) and magnetic nanocarriers for enhanced targeted drug delivery and imaging in cancer treatment.
  • Research showed that this composite significantly improves the release of the cancer drug cisplatin (over 75% release) compared to its individual components and exhibits good anticancer activity against various cancer cell lines (like MCF-7 and HeLa).
  • Additionally, the composite demonstrates antibacterial properties, making it a promising multifunctional platform for both cancer therapy and combating drug-resistant infections.

The combination of magnetic nanoparticles with a porous silica is a composite that has attracted significant attention for potential multifunctional theranostic applications. In this study, 30 wt % CuFeO was impregnated into a matrix of monodispersed spherical hydrophilic silica (HYPS) nanoparticles through a simple dry impregnation technique. The chemotherapy drug cisplatin was loaded through electrostatic equilibrium adsorption over 24 h in normal saline solution.

A novel random copolymer 4, containing diallylmethylamine and N,N-diallyl-N-methyl-N,N,N-tripropylhexane-1,6-diammonium dibromide units in a 1:1 ratio (polymer 4) was synthesized via Butler's cyclopolymerization technique. Characterization was accomplished by H NMR, elemental analysis, and Fourier-transform infrared spectroscopy (FTIR). Polymer 4 was tested as corrosion inhibitor for low carbon steel in 15% HCl solution via gravimetric and electrochemical approaches.

In this study, electron paramagnetic resonance (EPR) is used, for the first time, as an analytical tool for the quantitative assay of ketoconazole (KTZ) in drug formulations. The drug was successfully characterized by the prominent signals by two radical species produced as a result of its oxidation with 400 microg/mL cerium(IV) in 0.10 mol dm(-3) sulfuric acid.
