Evaluation of cumulative exposures to multiple pesticide residues in three characteristic fruits in the Northwest of Iran: a risk assessment using Monte Carlo Simulation.

This study was conducted to monitor and evaluate the health risks of multiple organophosphorus pesticide residues in three characteristic fruits of Maragheh district, East Azerbaijan province. The Monte Carlo method was used to quantify the possible non-carcinogenic health risks associated with pesticide residues in adults and children. The residues of 17 pesticides in 36 samples were analysed using the QuEChERS extraction method coupled with gas chromatography-mass spectrometry (GC/MS).

Serotyping and molecular profiles of virulence-associated genes among isolates from teaching hospitals of Ardabil, Iran: A cross-sectional study.

Background And Aims: is a Gram-negative bacterium that colonized various organs. This bacterium is associated with different community-acquired and hospital-acquired infections. The present study aims to assess the capsular serotypes and frequency of virulence-associated genes in isolates from teaching hospitals in Ardabil, Iran.

Cumulative health risk assessment of pesticide residues in apple products in the Northwest of Iran using Monte Carlo simulation.

Pesticide residues in fruits and vegetables cause serious health issues, especially among children. This research was carried out to monitor and evaluate the risks of organophosphate pesticide residues in Maragheh County apple products from 2020. The Monte Carlo Simulation approach (MCS) was used to evaluate the non-cancerous effects of exposure to pesticide residues in adults and children.

Conversion of glucose-xylose mixtures to pyruvate using a consortium of metabolically engineered .

Two strains of were engineered to accumulate pyruvic acid from two sugars found in lignocellulosic hydrolysates by knockouts in the , , , and genes. Additionally, since glucose and xylose are typically consumed sequentially due to carbon catabolite repression in , one strain (MEC590) was engineered to grow only on glucose while a second strain (MEC589) grew only on xylose. On a single substrate, each strain generated pyruvate at a yield of about 0.

A comparative study of dried apple using hot air, intermittent and continuous microwave: evaluation of kinetic parameters and physicochemical quality attributes.

In the study, the effectiveness of intermittent (IMWD) and continuous (CMWD) microwave drying and hot air drying (HAD) treatments on apple slices were compared in terms of drying kinetics (moisture diffusivity and activation energy) and critical physicochemical quality attributes (color change, rehydration ratio, bulk density, and total phenol content (TPC) of the final dried product. The temperature, microwave power, air velocity, and pulse ratio (PR) applied in the experiments were 40-80°C, 200-600 W, 0.5-2 m/s, and 2-6, respectively.
