In accordance with Article 43 of Regulation (EC) 396/2005, EFSA received a request from the European Commission to review the existing maximum residue levels (MRLs) for the non-approved active substance endosulfan in view of the possible lowering of the MRLs. EFSA investigated the origin of the current EU MRLs. For existing EU MRLs that reflect previously authorised uses in the EU, or that are based on obsolete Codex maximum residue limits, or import tolerances that are not required any longer, EFSA proposed the lowering to the limit of quantification or to an alternative MRL. EFSA performed an indicative chronic and acute dietary risk assessment for the revised list of MRLs to allow risk managers to take the appropriate decisions. For all commodities, further risk management discussions are required to decide which of the risk management options proposed by EFSA should be implemented in the EU MRL legislation.

Introduction: Equivocal or negative pituitary magnetic resonance imaging (MRI) findings raise a significant challenge in the management of persistent or recurrent Cushing's disease (CD), compromising the chances of success of a further transsphenoidal surgery (TSS). The aim of our study was to determine the diagnostic utility of 11C-methionine (MET) positron emission tomography coupled with computerized tomography (PET/CT) in localizing the residual or relapsing corticotroph adenoma.
Methods: We retrospectively analyzed the results of 11C-MET PET/CT performed in two tertiary medical centers between May 2002 and November 2023 in 22 patients with a persisting or recurrent CD after initial TSS and equivocal or negative pituitary MRI findings.

Understanding protein fermentation in the hindgut of pigs is essential due to its implications for health, and ileal digesta is commonly used to study this process . This study aimed to assess the feasibility of utilizing digested residues as a replacement for ileal digesta in evaluating the protein fermentation potential. residues from cottonseed meal, maize germ meal, peanut meal, rapeseed cake, rapeseed meal, soybean meal and sunflower meal were analysed using a modified gas production (GP) technique and curve fitting model to determine their fermentation dynamics and compare with the use of ileal digesta.

Due to the high toxicity and increasing consumption, efficient removal of phenoxyacetic acid herbicides (PAAHs) from water is imperative. In current study, a new adsorbent was prepared by modifying porous carbon derived from disused floral foam with chitosan (CS) (ACFC). Density functional theory (DFT) calculation uncovered that the amino and hydroxyl groups in the introduced CS played a critical role in the efficient adsorption of ACFC towards PAAHs.

The bioaccumulation of pesticides in honeybee products (HBPs) should be studied for a number of reasons. The presence of pesticides in HBPs can provide new data on the risk related to the use of pesticides and their role in bee colony losses. Moreover, the degree of contamination of HBPs can lower their quality, weaken their beneficial properties, and, in consequence, may endanger human health.
