A new, rapid, simple, and sensitive preconcentration method and Spectrophotometry determination technique have been presented for the microextraction and determination of trace amount of Tartrazine dye in food samples. In the present system, which is called "Magnetic stirring in syring dispersive liquid-liquid microextraction"(MSIS- DLLME), a cloudy state result is formed in a homemade glass syringe by magnetic agitation. In the MSIS-DLLME system, Tartrazine colour was uprooted into an organic detergent (Toluene) after many twinkles. Subsequently, the organic detergent which was placed on top of the result was transferred into a narrow neck by moving the piston overhead. The effective parameters on the extraction recovery were studied and optimized by Central Composite design (CCD). Under the optimum conditions, the estimation cure is direct in the range of 0.1-1(μg L). The limit of detection (LOD), relative standard divagation and enrichment factor were 0.03 μg L , ±4.6 (n = 10) and 166, independently. The advanced system was successfully applied for microextraction of Tartrazine in food samples.

Microneedle (MN) sensors have great promise for food safety detection, but the rapid preparation of MNs for surface-enhanced Raman scattering (SERS) sensors with tunable and homogeneous nanoparticles remains a great challenge. To address this, a SERS sensor of gold nanoparticles@polydopamine@poly(methyl methacrylate) MN (AuNPs@PDA@PMMA-MN) was developed. The extended-Derjaguin-Landau-Verwey-Overbeek theory was applied to calculate the interaction energy between AuNPs and PDA.

Objective: The study examines: 1) impacts of COVID-19 on the work of Supplemental Nutrition Assistance Program - Education (SNAP-Ed) implementers, 2) facilitators and barriers experienced in making adaptations, and 3) factors that would have helped with preparedness to adapt.
Design, Setting, And Participants: A purposive sample of 181 SNAP-Ed program implementers from across five states completed a survey or interview based on the study aims. Quantitative data was summarized with descriptive statistics and qualitative data was analyzed thematically.
Does curcumin supplementation affect inflammation, blood count and serum brain-derived neurotropic factor concentration in amateur long-distance runners?

Curcumin is known for its potential health benefits; however, the evidence remains inconclusive regarding its necessity as a supplement for athletes during the preparatory phase of training. This study aimed to assess the effect of 6-week curcumin supplementation at a dose of 2g/day on selected inflammatory markers, blood count, and brain-derived neurotropic factor (BDNF) levels in middle-aged amateur long-distance runners during the preparatory period of a macrocycle. Thirty runners were randomly assigned to either a curcumin-supplemented group (CUR, n = 15) or a placebo group (PLA, n = 15).

From February 2022 to April 2023, a cross-sectional study on dog gastrointestinal parasites was conducted in Bishoftu, Dukem, Addis Ababa, and Sheno, Central Ethiopia, with the aim of estimating the prevalence and evaluating risk factors. A total of 701 faecal samples were collected and processed using floatation and McMaster techniques. In dogs that were investigated, the overall prevalence of gastrointestinal parasites was 53.

Background: Pakistani women are among the most affected groups by obesity and heart failure in Catalonia. Due to cultural and linguistic barriers, their participation in standard health promotion programs is limited. To address this issue, we implemented a culturally and linguistically appropriate food education program called the PakCat Program.
