“…Nissl staining was used to identify the functional regions of the telencephalon and explore the morphological differences and changes in the state and distribution of the neurons in the telencephalon between wild type and cerebral hernia type chickens as described previously [ 10 , 29 ]. Thionin (0.1 g) was added to 100 mL double distilled water to prepare Nissl staining solution.…”

Cerebral hernia in crested chicken has been characterized as the protrusion of cerebral hemispheres into the unsealed skull for hundreds of years, since Charles Darwin. The development of deformed forebrain (telencephalon) of cerebral hernia remains largely unknown. Here, the unsealed frontal skull combined with misplaced sphenoid bone was observed and potentially associated with brain protuberance. The shifted pallidum, elongated hippocampus, expanded mesopallium and nidopallium, and reduced hyperpallium were observed in seven regions of the malformed telencephalon. The neurons were detected with nuclear pyknosis and decreased density. Astrocytes showed uneven distribution and disordered protuberances in hyperpallium and hippocampus. Transcriptome analyses of chicken telencephalon (cerebral hernia vs. control) revealed 547 differentially expressed genes (DEGs), mainly related to nervous system development, and immune system processes, including astrocyte marker gene GFAP, and neuron and astrocyte developmental gene S100A6. The upregulation of GFAP and S100A6 genes in abnormal telencephalon was correlated with reduced DNA methylation levels in the promoter regions. The morphological, cellular, and molecular variations in the shape, regional specification, and cellular states of malformed telencephalon potentially participate in brain plasticity and previously reported behavior changes. Chickens with cerebral hernia might be an interesting and valuable disease model to further explore the recognition, diagnosis, and therapy of cerebral hernia development of crested chickens and other species.

“…Furthermore, several studies have shown that the protective effect of TQ against cardiac damage, such as in cases of ischemic damage [ 13 ] and acute abdominal aortic ischemia-reperfusion injury [ 14 ], is mediated via the pyroptosis pathway [ 15 ]. Recently, pyroptosis, an inflammatory form of programmed cell death [ 16 ], has been gaining increasing attention, especially in relation to hyperlipidemia [ 17 , 18 ]; however, the pathophysiological mechanisms underlying the relationship between hyperlipidemia and cardiac damage are not yet fully understood.…”

Hyperlipidemia is a risk factor for cardiac damage and cardiovascular disease. Increasing evidence has shown that dyslipidemia-related cardiac damage is associated with lipid accumulation, oxidative stress, and inflammation. Thymoquinone (TQ) is the major constituent of Nigella sativa, commonly known as black seed or black cumin, and is globally used in folk (herbal) medicine for treating and preventing a number of diseases and conditions. Several studies have shown that TQ can protect against cardiac damage. This study is aimed at investigating the possible protective effects of TQ on hyperlipidemia-induced cardiac damage in low-density lipoprotein receptor-deficient (LDL-R-/-) mice. Eight-week-old male LDL-R-/- mice were randomly divided into normal diet (ND), high-fat diet (HFD), and HFD and TQ (HFD+TQ) groups and were fed the different diets for eight weeks. Blood samples were obtained from the inferior vena cava in serum tubes and stored at -80°C until use. Some cardiac tissues were fixed in 10% formalin and then embedded in paraffin for histological evaluation. The remainder of the cardiac tissues was snap-frozen in liquid nitrogen for mRNA preparation or immunoblotting. The levels of metabolism-related factors, such as total cholesterol (TC), low-density lipoprotein-cholesterol (LDL-c), and high-sensitivity C-reactive protein (hs-CRP), were decreased in the HFD+TQ group compared with those in the HFD group. Periodic acid-Schiff staining demonstrated that lipid deposition was lower in the HFD+TQ group than in the HFD group. The expression of pyroptosis indicators (NOD-like receptor 3 (NLRP3), interleukin- (IL-) 1β, IL-18, and caspase-1), proinflammatory factors (IL-6 and tumor necrosis factor alpha (TNF-α)), and macrophage markers (cluster of differentiation (CD) 68) was significantly downregulated in the HFD+TQ group compared with that in the HFD group. Our results indicate that TQ may serve as a potential therapeutic agent for hyperlipidemia-induced cardiac damage.

“…Paeoni orin (PF) is extracted from the Astragalus propinquus, which can inhibits prothrombin production and platelet aggregation, dilates veins and peripheral small blood vessels, improves blood microcirculation, resists cerebral ischemia-reperfusion injury, and can improve blood-brain barrier permeability [7][8][9] . Calycosin-7-glucoside (CG) is extracted from the root of Paeonia lacti ora Schischkin, which can relaxes blood vessels and stimulates microvessels to improve hemodynamics and protect the integrity of the blood-brain barrier in experimental reperfusion cerebral ischemia 10 .…”

Background Paeoniflorin (PF) and calycosin-7-glucoside (CG) play a role in protecting against brain damage following cerebral ischemia. However, the mechanism of action of PF in combination with CG (PF + CG) against ischemia/reperfusion injury remains unclear. Methods The aim of this study was to investigate the protective role of PF + CG on ischemia/reperfusion injury in vivo and in vitro, as well as its potential mechanism of action indicating that PF + CG attenuates middle cerebral artery occlusion (MCAO) /oxygen-glucose deprivation reperfusion (OGD/R) injury via the PI3K/AKT pathway. MCAO rat model was prepared by modified suture method, and behavioral scoring, cerebral infarction area, brain tissue water content measurement, using PI3K, p-PI3K, AKT, p-AKT, Bcl-2, Bax, GSK-3β protein expression as indicators, observe the effect of PI3K / AKT signaling pathway inhibitor LY294002 on the anti-ischemia-reperfusion effect of PF + CG. Oxygen deprivation method was used to prepare the OGD/R model, CCK-8 was used to determine the survival rate of HT22 cells, the contents of SOR, ROS, MDA, and LHD were determined, and apoptosis was detected by flow cytometry and mitochondrial membrane potential, using PI3K, p-PI3K, AKT, p-AKT, Bcl-2, Bax, GSK-3β protein expression as indicators, observe the effect of PI3K/AKT signaling pathway inhibitor LY294002 on the anti- oxidative and glucose deprivation effect of PF + CG. Results The animal studies showed that PF + CG significantly decreased neurobehavioral deficits, cerebral infarct volume, and brain edema; ameliorated histopathological damage in model rats; increased levels of PI3K, AKT, p-PI3K, p-AKT, and Bcl-2; and reduced BAX and GSK-3β expression. After treatment with PF + CG, the morphology and number of cells in brain tissue were restored to normal, demonstrating a therapeutic effect in cerebral ischemia-reperfusion injury. Results of further studies revealed that, in vitro, PF + CG has a therapeutic effect to enhance cell vitality; elevate levels of superoxide dismutase (SOD); reduce levels of reactive oxygen species (ROS), lactate dehydrogenase (LDH), and malondialdehyde (MDA); decrease apoptosis rate; increase levels of PI3K, AKT, p-PI3K, p-AKT, and Bcl-2; and reduce BAX and GSK-3β expression. Conclusion These results demonstrate that PF + CG has a positive therapeutic effect on ischemia/reperfusion and OGD/R injury, and the mechanism is attributed to activation of the PI3K/AKT signaling pathway.
