Complex multisource sound induces greater neurodegeneration in neonatal rat brain than single-source sound

January 28, 2026

İskender Samet Daltaban1†, Mehmet Dumlu Aydın2, Eylem Eren Eyüpoğlu3, Elif Demirci4†, Aybike Aydin Okuyan5†Mehmet Emin Demir6*† Background: Excessive noise exposure is a known environmental health hazard linked to neurological injury and cognitive deficits. Whether complex sound waveforms from multiple sources exacerbate brain damage compared to a single-source noise of equal intensity remains unclear. We investigated […]

Architecture and cellular composition of focal cortical dysplasia type II: qualitative review of histological studies

January 22, 2026

Focal cortical dysplasia (FCD) is a malformation of cortical development strongly associated with drug-resistant epilepsy, particularly in children but also observed in adults. FCD type II is specifically characterised by cortical disorganisation and the presence of abnormal cells. This condition has been widely linked to hyperactivation of the mTOR signalling pathway, secondary to somatic mutations. […]

Multi-omics and perturbation screens as discovery tools in immunometabolism

January 22, 2026

by Nicole M. Chapman, Hongbo Chi Metabolic rewiring of immune cells has broad impacts on immune responses and disease outcomes. Systems biology approaches, such as multi-omics profiling and perturbation screening, could uncover new actionable targets and therapeutic avenues to explore. Metabolic regulation of immune function is a complex and dynamic process. This Perspective highlights how systems biology […]

Montiel-Castro, Hypatia Arano-Varela, Pablo Adolfo Mayer-Villa, José Eleazar Aguilar-Toalá, José Luis Montesillo-Cedillo and Ana Karen Talavera-Peña We offer an integrative perspective on how the air-pollution exposome shapes fetal development during the first 1,000 days and reverberates across mental health and behavior. Pregnant individuals […]

Prospects for nasal delivery of a pharmacologic agent for neuroprotective experimental therapy after prenatal hypoxia

December 10, 2025

by Igor Belenichev, Olena Aliyeva, Nina Bukhtiyarova, Victor Ryzhenko, Bogdan Burlaka, Kristina Burlaka, Dmytro Skoryna, Pavlo Petakh, Oleksandr Kamyshnyi Prenatal hypoxia (PH) significantly impacts the central nervous system (CNS) development, often resulting in long-term cognitive, behavioral, and neurological deficits due to oxidative stress, mitochondrial dysfunction, and neuroapoptosis. The brain’s endogenous protective mechanisms are often insufficient […]

HIF1A-mediated pathways promote euploid cell survival in chromosomally mosaic embryos

December 8, 2025

by Estefania Sanchez-Vasquez, Marianne E Bronner, Magdalena Zernicka-Goetz Human fertility is suboptimal in part by error-prone divisions during early cleavage stages, which frequently result in chromosomal aneuploidy. Most human pre-implantation embryos are mosaics of euploid and aneuploid cells, yet those with a low proportion of aneuploid cells can develop to term at rates similar to […]
