This study was planned and executed to investigate the effects of two levels of compound toxin binder (CTB) on growth performance, serum biochemistry, antioxidant status, intestinal morphology, and the ileal selected microflora population in broiler chickens. A total of 240 one-day-old Ross 308 broiler chickens were divided into four treatments and six replicates (10 chickens per replicate). Experimental groups included; 1, negative control (NC; no aflatoxins (AFs) and no additives); 2, positive control (PC; 490 µg/kg AFs); 3, low levels of compound toxin binder (LCTB), PC + 1 g/kg available CTB (Navacidox); and 4, high levels of compound toxin binder (HCTB), PC + 2 g/kg Navacidox.

Department of Regenerative Medicine, Cell Science Research Center, Royan Institute for Stem Cell Biology and Technology, ACECR, Tehran, Iran; Experimental Cancer Medicine, Institution for Laboratory Medicine, Karolinska Institute, 141-83 Stockholm, Sweden. Electronic address:

Background And Objective: Myeloid-derived suppressor cells (MDSCs) are a crucial and diverse group of cells found in the tumor microenvironment (TME) that facilitate progression, invasion, and metastasis within solid tumors. CD84, a homophilic adhesion molecule expressed on MDSCs, plays a critical role in their accumulation and function within the TME. This study aims to investigate the protein-protein interactions of CD84 using molecular dynamics simulations and to explore potential therapeutic strategies targeting these interactions.

Background: Coronary artery disease (CAD) is the third leading cause of death worldwide, so prevention and early diagnosis play important roles to reduce mortality and morbidity. Traditional risk-score assessments were used to find the at-risk patients in order to prevent or early treatment of CAD. Adding imaging data to traditional risk-score systems will able us to find these patients more confidently and reduce the probable mismanagements.

Introduction: Opium and cigarette smoking have been identified as significant cancer risk factors. Recently, the International Agency for Research on Cancer (IARC) classified opium as a Group 1 carcinogen in 2020.

Method: Using data from a multicenter case-control study in Iran called IROPICAN, involving 717 cases of bladder cancer and 3477 controls, we assessed the interactions on the causal additive scale between opium use and cigarette smoking and their attributing effects to evaluate public health relevance and test for different mechanistic interaction forms to provide new insights for developing of bladder cancer.

This review examines the emerging applications of machine learning (ML) and radiomics in the diagnosis and prediction of placenta accreta spectrum (PAS) disorders, addressing a significant challenge in obstetric care. It highlights recent advancements in ML algorithms and radiomic techniques that utilize medical imaging modalities like magnetic resonance imaging (MRI) and ultrasound for effective classification and risk stratification of PAS. The review discusses the efficacy of various deep learning models, such as nnU-Net and DenseNet-PAS, which have demonstrated superior performance over traditional diagnostic methods through high AUC scores.

Background: With recent advances in clinical practice, including the use of reduced-toxicity conditioning regimens and innovative approaches such as ex vivo TCRαβ/CD19 depletion of haploidentical donor stem cells or post-transplant cyclophosphamide (PTCY), hematopoietic stem cell transplantation (HSCT) has emerged as a curative treatment option for a growing population of patients with inborn errors of immunity (IEI). However, despite these promising developments, graft failure (GF) remains a significant concern associated with HSCT in these patients. Although a second HSCT is the only established salvage therapy for patients who experience GF, there are no uniform, standardized strategies for performing these second transplants.
