Prevalence and factors associated with continual opioid use among patients attending methadone clinic at Mwananyamala Hospital, Dar Es Salaam, Tanzania

Trends of continual drug use while under treatment have been reported worldwide. This paper assesses opioid use among patients receiving treatment in a methadone clinic for opioid addiction. A total of 126 urine samples were analyzed using ...

miR-3113-5p, miR-223-3p, miR-133a-3p, and miR-499a-5p are sensitive biomarkers to diagnose sudden cardiac death

Abstract Background Sudden cardiac death (SCD) remains a great health threat and diagnostic challenge, especially those cases without positive autopsy findings. Molecular biomarkers have been urgently needed for the diagnosis of SCD display...

Simultaneous analysis of creatinine and uric acid in human urine samples using mean centering, ratio subtraction, and derivative spectrophotometric techniques as a green analytical protocol

Four rapid, accurate, and straightforward derivative spectrophotometric methods were developed to quantify a binary mixture of creatinine (CRT) and uric acid (UA) in human urine samples. The first technique was based on a zero-crossing tech...

Improving Minutiae Image of Latent Fingerprint Detection on Non-Porous Surface Materials under UV Light Using Sulfur Doped Carbon Quantum Dots from Magnolia Grandiflora Flower

In this study, carbon quantum dots (CQDs) from Magnolia Grandiflora flower as a carbon precursor were obtained using a hydrothermal method under the optimized conditions affected by various heating times (14, 16, 18, and 20 min) and various...

Preparation of Modified Kaolin Filler with Cesium and Its Application in Security Paper

In this study, cesium was added intentionally during paper manufacture for protecting the papers against forgery and counterfeiting by sorbing cesium ions (Cs+) on kaolin, used as special filler in papermaking. The sorption of cesium from a...

Optimization of Bacillus cereus Fermentation Process for Selenium Enrichment as Organic Selenium Source

Selenium is an essential trace element and micronutrient for human health. Application of organic selenium in plants and microorganisms as trace element supplement is attracting more and more attention. In this study, Bacillus cereus, an im...

Green Synthesized Zinc Oxide Nanoparticles Using <i>Moringa olifera</i> Ethanolic Extract Lessens Acrylamide-Induced Testicular Damage, Apoptosis, and Steroidogenesis-Related Gene Dysregulation in Adult Rats

This study assessed the possible protective role of green synthesized zinc oxide nanoparticles using Moringa olifera leaf extract (MO-ZNPs) in acrylamide (ACR)-induced reproductive dysfunctions in male rats. ACR (20 mg/kg b.wt/day) and/or M...

From plants to patterns: Constructing a comprehensive online strontium isoscape for Belgium (IsoBel) using high density grid mapping

Understanding the spatial distribution of strontium isotopes in plants or other archives within a region is crucial for various fields, including archaeology, environmental studies, food sciences and forensic science. This study aims to cre...

A sustainable supramolecular deep eutectic solvent system for dispersive liquid–liquid microextraction followed by HPLC for the determination of melamine in milk samples

This work presents the development and application of an innovative green supramolecular deep eutectic solvent (SUPRADES)-based DLLME approach for the extraction and quantification of melamine in milk matrices. For this purpose, thymol and ...

Case report: Incidentally discovered case of pheochromocytoma as a cause of long COVID-19 syndrome

Pheochromocytomas (PCCs) are rare but potentially lethal tumors that arise from the adrenal medulla. The clinical suspicion and diagnosis of PCC can be challenging due to the non-specific nature of signs and symptoms. In many patients, infe...

Unraveling the formation mechanism of 3-methylindole from tryptophan in the glucose-mediated Maillard reaction: a combined ReaxFF MD, DFT, and experimental study

3-Methylindole is a concentration-dependent aroma compound, and its formation mechanism in the tryptophan-glucose Maillard reaction is crucial for flavor regulation but remains incompletely elucidated. Using gas chromatography-olfactometry-...

Effect of Nano-multi Micronutrients on Agronomic Traits, Nutrient Uptake and Soil Fertility in Pot Trial of Maize (Zea mays L.)

A pot experiment of maize was carried during summer seasons of March–July, 2023 and 2024 at the experimental field of Rashtriya Chemicals and Fertilizers, Mumbai, India, to assess the impact of multi nano micronutrients formulation (NM) on ...

Anti-inflammatory activity of two varieties of pumpkin seed oil in an adjuvant arthritis model in rats

The aim of the present research was to evaluate the anti-inflammatory activity of pumpkin seed oils (PSOs) of an Egyptian and European variety, in a rat model of adjuvant arthritis. Edema thickness, plasma tumor necrosis factor-α (TNF-α) an...

Natural Polyphenols for the Preservation of Meat and Dairy Products

Food spoilage makes foods undesirable and unacceptable for human use. The preservation of food is essential for human survival, and different techniques were initially used to limit the growth of spoiling microbes, e.g., drying, heating, sa...

EXTRACTION OF COPPER FROM LEACH LIQUOR OF METALLIC COMPONENT IN DISCARDED CELL PHONE BY CYANEX® 272

Discarded cell phones contribute significantly to the amount of electronic waste generation whilst some of its components are toxic and recoverable. Also, due to the increasing demand for Cu(II) in building/construction, electrical and as c...

Negative emissions technologies and practices could challenge global resource supply and environmental limits

Abstract Meeting climate goals will most likely require large-scale carbon dioxide removal, yet its sustainability implications remain poorly understood. Here, we conduct a prospective life cycle assessment of multiple negative emissions te...

NLRP3 Inflammasome-Mediated Pyroptosis Pathway Contributes to the Pathogenesis of Candida albicans Keratitis

PurposeFungal keratitis is a sight-threatening corneal infection caused by fungal pathogens, and the pathogenic mechanisms have not been fully elucidated. The aim of this study was to determine whether NOD-like receptor family pyrin domain ...

Influence of priming on germination, development, and yield of soybean varieties

A two-factorial field experiment with soybean (Glycine max (L.) Merill) was conducted in a randomized block design, with four replications. The tested factors were seed priming method and genotype responses. There had been seven soybean var...

Electrochemical Sensor for Simple and Sensitive Determination of Hydroquinone in Water Samples Using Modified Glassy Carbon Electrode

This study addressed the use of manganese dioxide nanorods/graphene oxide nanocomposite (MnO2 NRs/GO) for modifying a glassy carbon electrode (GCE). The modified electrode (MnO2 NRs/GO/GCE) was used as an electrochemical sensor for the dete...
