Tributyltin is used in industrial applications. This current research aimed to study the effect of Tributyltin on the thyroid gland structure and function of adult male albino rats and the protective effect of Lycopene. Twenty-one male adult albino rats were classified into three groups: Control, treated that received Tributyltin, and protective that received Lycopene with Tributyltin. At the end of the experiment, blood samples were collected and T4, T3, and (TSH) were measured. Tissue superoxide dismutase (SOD) and malondialdehyde (MDA) were estimated. Thyroid gland specimens were processed for histological and immunohistochemical examination. Then morphometric and statistical analyses were done. The treated group showed affection in thyroid function and histological structure as vacuolated colloid and cytoplasm and dark nuclei. Ultrastructurally, follicular cells showed irregular shrunken nuclei, atrophied apical microvilli, vacuoles, multiple lysosomal granules, mitochondria with destructed cristae, and extensively dilated rough endoplasmic reticulum. There was increase in Caspase-3 immunoexpression and decrease in Beclin-1 immunoexpression. The thyroid structure and biochemical markers improved after Lycopene administration. The thyroid gland damage caused by Tributyltin is ameliorated by Lycopene.

The pineal gland secretes melatonin, which regulates various physiological processes; damage to this gland disrupts these functions. This study aimed to investigate the effect of nonylphenol on the pineal gland and the pituitary-adrenal axis, which is associated with this system. The study was initiated using Wistar albino male rats on their postnatal 21st day, a critical developmental stage for endocrine regulation.

Introduction: Alzheimer's disease is a developing public health concern in aging communities that affects a sizable section of the global population. The risk of Alzheimer's disease increases with age; it affects one-third of males and two-thirds of women This research attempts to assess the effect of nano-selenium and thymoquinone on Nrf2 gene expression levels in Alzheimer's disease (AD).
Methods: There were five identical groups of 50 albino male rats: a control group that was healthy; an AD positive control group; an AD group that received nano-selenium (5 mg/kg); an AD group that received thymoquinone (2 mg/kg); and an AD group that received both.

Background: Acute systemic inflammation affects many organs and it occurs in a wide range of conditions such as acute lung injury (ALI). Inflammation-triggered oxidative pathways together with the caspase activation seen in ALI, result in apoptosis. Dapagliflozin (DPG) is an agent that is known to have oxidative stress-reducing and anti-inflammatory effects in many tissues.

Secondary brain damageafter traumatic brain injury (TBI) involves oxidative stress, neuroinflammation, apoptosis, and necroptosis and can be reversed by understanding these molecular pathways. The objective of this study was to examine the impact of tasimelteon (Tasi) administration on brain injury through the nuclear factor erythroid 2-related factor 2 (NRF-2)/heme oxygenase-1 (HO-1) and receptor-interacting protein kinase 1 (RIPK1)/receptor-interacting protein kinase 3 (RIPK3)/mixed lineage kinase domain-like (MLKL) pathways in rats with TBI. Thirty-two male Wistar albino rats weighing 300-350 g were randomly divided into four groups: the control group, trauma group, Tasi-1 group (trauma + 1 mg/kg Tasi intraperitoneally), and Tasi-10 group (trauma + 10 mg/kg Tasi intraperitoneally).
