AI Article Synopsis
- The study assesses the environmental impacts of egg production from laying hens in Alborz province, Iran, focused on one kilogram of eggs produced over 420 days for 1,000 chickens.
- The evaluation concentrated on the main dietary components (corn, soybean, and wheat), which account for 80% of the chicken diet, using data from the EcoInvent 2.0 database and analyzed with SimaPro software.
- Key impact indicators, including greenhouse gas emissions and energy use, were calculated, revealing that diet production had the most significant negative environmental impact.
Article Abstract
In this study we have to deal with the assessment of environment impacts of laying hen in the Alborz province, Iran. This assessment was carried out for one kg of egg during a period of 420 days for 1000 chickens. Then due to significant consumption of diet during period of question, three main products including corn, soybean and wheat which are consist of 80 percent of the combination of laying chicken diet, also collected the information about their production and it has been evaluated the indicators of their environment individually and eventually, the results has been considered as a title for inputs of poultry. Data for production of inputs were taken from EcoInvent 2.0 database, and SimaPro software was used for analysis. Ten classification impacts including Abiotic Depletion potential, Acidification potential, Eutrophication potential, Global Warming potential for time horizon 100 years, Ozone Depletion potential, Human Toxicity potential, Freshwater and Marine Aquatic Eco-toxicity potential, Terrestrial Eco-toxicity potential, and Photochemical Oxidation potential were selected based on the CML 2 baseline 2000 V2/world, 1990/characterization method. Due to the results, for each kilograms of egg, 30/09 MJ and also the value of greenhouse gas emissions is 4/07 Kg CO eq was calculated. According to the obtained results, the production of diet has made the most negative charge of environment among the inputs.

Myelodysplastic Neoplasm (MDS) is a cancer associated with aging, often leading to acute myeloid leukemia (AML). One of its hallmarks is hypermethylation, particularly in genes responsible for DNA repair. This study aimed to evaluate the methylation and mutation status of DNA repair genes (single-strand - XPA, XPC, XPG, CSA, CSB and double-strand - ATM, BRCA1, BRCA2, LIG4, RAD51) in MDS across three patient cohorts (Cohort A-56, Cohort B-100, Cohort C-76), using methods like pyrosequencing, real-time PCR, immunohistochemistry, and mutation screening.

We argue that "processes versus objects" is not a useful dichotomy. There is, instead, substantial theoretical utility in viewing "objects" and "processes" as complementary ways of describing persistence through time, and hence the possibility of observation and manipulation. This way of thinking highlights the role of memory as an essential resource for observation, and makes it clear that "memory" and "time" are also mutually inter-defined, complementary concepts.

Purpose: To develop and validate an MRI-based model for predicting postoperative early (≤2 years) recurrence-free survival (RFS) in patients receiving upfront surgical resection (SR) for beyond Milan hepatocellular carcinoma (HCC) and to assess the model's performance in separate patients receiving neoadjuvant therapy for similar-stage tumors.
Method: This single-center retrospective study included consecutive patients with resectable BCLC A/B beyond Milan HCC undergoing upfront SR or neoadjuvant therapy. All images were independently evaluated by three blinded radiologists.

Two-dimensional Transition Metal Dichalcogenides (2D TMDs) have garnered significant attention in the field of materials science due to their remarkable electronic and optoelectronic properties, including high carrier mobility and tunable band gaps. Despite the extensive research on various TMDs, there remains a notable gap in understanding the synthesis techniques and their implications for the practical application of monolayer tungsten disulfide (WS2) in optoelectronic devices. This gap is critical, as the successful integration of WS2 into commercial technologies hinges on the development of reliable synthesis methods that ensure high quality and uniformity of the material.
