This study examined the heavy metal content in dust storm samples from Erbil, Iraq, along with four other locations. Using ICP-MS, Cd, Ni, Cr, Hg, Pb, Zn, Mn, Cu, Co, Fe and As were determined. The health risks due to exposure to these metals through ingestion, inhalation and dermal contact were assessed for both adults and children. Non-carcinogen...
Given the significant quantity of betalain pigments, beetroot represents a potential source of natural colorants that can be employed in the food industry. The present investigation explored the impact of ethanolic beetroot peel (EBP) extract in beef meat preservation. EBP displayed a 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging effect wit...
Tis study reports on developing a simple, cost-effective, highly sensitive spectrophotometric method for measuring mesalazine (MSZ). The method utilizes the oxidative coupling of MSZ with syringic acid (4-hydroxy 3,5-dimethoxybenzoic acid) in the presence of dissolved oxygen under alkaline conditions to form a stable indophenol dye with a character...
This study explored the impact of date palm seeds ethanolic extract (DSEE) on the microbiological, physicochemical, and sensory qualities of chicken breast meat kept refrigerated at 4 °C. DSEE was applied at 0.156% (DSEE1), 0.312% (DSEE2), and 0.624% (DSEE4). Microbiological parameters, chemical stability, and sensory features of DSEE were monitore...
Novel spectrophotometric and smartphone-based colorimetric methods were developed and validated for the estimation of atenolol (ATE) in pharmaceutical formulations. The measurement procedure is based on the de-diazotization reaction, in which ATE is able to inhibit the diazotized sulfanilic acid from reacting with 8-hydroxy quinoline (8-HQ) in a ba...
A simple and accurate spectrophotometric technique has been presented for determining the presence of loperamide hydrochloride. The approach involves forming an ion-pair association complex with rose Bengal (RB), which results in a colored product that is analyzed spectrophotometrically at 568 nm. The validity of Beer’s law was established in the r...
The risk to human health from heavy metals is primarily associated with the consumption of foodstuffs that are contaminated with these metals. This study aimed to assess the health risks associated with the consumption of toxic metal-contaminated legumes in Erbil, Iraq. The concentrations of 14 metals, namely cadmium (Cd), lead (Pb), zinc (Zn), cop...
This study used a hydrothermal approach to create a sensitive and focused nanoprobe. Using an “on-of-on” sensing mechanism, the nanoprobe was employed to detect and quantify ferric ions and L-ascorbic acid. Synthesis of the carbon quantum dots was achieved with a single hydrothermal step at 180° C for 24 hours using hot pepper as the starting mater...
Colorectal cancer (CRC) is considered a lethal cancer all around the world, and its incidence has been reported to be increasing. Chemotherapeutic drugs commonly used for treating this cancer have shown some drawbacks, including toxicity to healthy cells and non-precise delivery. Thus, there is a necessity for discovering novel diagnostic and thera...
Simple, accurate, precise, and cost-effective chemometric techniques for the measurement of candesartan cilexetil and hydrochlorothiazide in synthetic mixtures were improved and validated. H-point standard addition, Q-absorption ratio, and correction absorbance spectrophotometric techniques were utilized for the simultaneous determination of both m...
The simultaneous analysis of a ternary mixture containing paracetamol (PAR), phenylephrine hydrochloride (PHE), and chlorpheniramine maleate (CPM) was conducted without prior separation and using an advanced spectrophotometric method. The H-point standard addition and absorbance correction methods were selected to determine the compounds, which are...
Breast cancer is one of the leading causes of death and is the most routine form of cancer in women in the world. Carbohydrate antigen 15–3 (CA15–3) tumor marker is a serum-based product of the MUC1 gene and different studies have determined the over-regulation of this tumor marker in breast cancer. Moreover, CA15-3 is overexpressed in a number of...
