Abstract
Atherosclerosis can cause severe cardiovascular diseases, which is the most common cause of death in the world. It's of great significance to study the prevention and treatment of atherosclerosis. Selenium nanoparticles (SeNPs) has drawn more and more attention due to high biological activity, high bioavailability, strong antioxidant capacity and low toxicity, exhibiting great potential in biomedical application. Thus, this study aimed at explore the anti-atherosclerotic effect of two kinds of SeNPs, bovine serum albumin (BSA) surface-decorated SeNPs and chitosan (CS) surface-decorated SeNPs (CS-SeNPs), in apolipoprotein E deficient (ApoE-/-) mice fed with a high-cholesterol and high-fat diet, and the possible mechanisms. The results demonstrated that both BSA-SeNPs (25, 50 and 100 μg Se/kg body weight/day) and CS-SeNPs (50 μg Se/kg body weight/day) could reduce atherosclerotic lesions in ApoE-/- mice after oral administration for 12 weeks. And these effects might mainly attributed to the ability of BSA-SeNPs and CS-SeNPs to inhibit hyperlipidemia by suppressing hepatic cholesterol and fatty acid metabolism, and alleviate oxidative stress by enhancing antioxidant activity. Moreover, the benefits of BSA-SeNPs were dose-dependent and the medium dose of BSA-SeNPs (50 μg Se/kg body weight/day) was optimal. Generally, BSA-SeNPs with mean size 38.5 nm and negative surface charge showed better anti-atherosclerotic effect than CS-SeNPs with mean size 65.8 nm and positive surface charge. These results suggested that SeNPs could significantly alleviate the formation of atherosclerosis in ApoE-/- mice, possibly by inhibiting hyperlipidemia and oxidative stress, exhibiting a potential to serve as an anti-atherosclerotic agent.

Calcium Carbonate Nanoparticles-Toxicity and Effect of In Ovo Inoculation on Chicken Embryo Development, Broiler Performance and Bone Status. Animals (Basel) 2021; 11:ani11040932. [PMID: 33805968 PMCID: PMC8064363 DOI: 10.3390/ani11040932] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2021] [Revised: 03/21/2021] [Accepted: 03/23/2021] [Indexed: 12/14/2022] Open
Abstract
Simple Summary Intensive selection in broiler chicken flocks has led do several leg disorders. The injection of nanoparticles, with high specificity to the bone, into the egg is a potential method to improve bone quality. The objective of our study was to evaluate the potential effect of calcium carbonate nanoparticles injected to the egg on chicken embryo development and bone quality of broiler chickens after 42 day of life. The calcium carbonate nanoparticles were not toxic to embryo and even improved the bone quality of embryos and later broilers without negative impact on production results. Thus, the application of calcium carbonate nanoparticles to the egg may be the potential solution for improving the bone mineralization of broiler chickens. Abstract The use of intensive selection procedure in modern broiler chicken lines has led to the development of several skeletal disorders in broiler chickens. Therefore, current research is focused on methods to improve the bone quality in birds. In ovo technology, using nanoparticles with a high specificity to bones, is a potential approach. The present study aimed to evaluate the effect of in ovo inoculation (IOI) of calcium carbonate nanoparticles (CCN) on chicken embryo development, health status, bone characteristics, and on broiler production results and bone quality. After assessing in vitro cell viability, the IOI procedure was performed with an injection of 500 μg/mL CCN. The control group was not inoculated with CCN. Hatchability, weight, and selected bone and serum parameters were measured in embryos. Part of hatchlings were reared under standard conditions until 42 days, and production results, meat quality, and bone quality of broilers were determined. CCN did not show cytotoxicity to cells and chicken embryo and positively influenced bone parameters of the embryos and of broilers later (calcification) without negatively affecting the production results. Thus, the IOI of CCN could modify the molecular responses at the stage of embryogenesis, resulting in better mineralization, and could provide a sustained effect, thereby improving bone quality in adult birds.

Abstract
BACKGROUND Hepatic estrogen signaling, which is important in liver injury/recovery, is determined by the level of systemic estrogen and hepatic estrogen receptor. We aimed to evaluate whether female's advantage in the tolerance of hepatic ischemia-reperfusion injury decreases according to the age of 40 y (systemic estrogen decrease) and macrosteatosis (hepatic estrogen receptor decrease). METHODS We included 358 living liver donors (128 females and 230 males). The tolerance of hepatic ischemia-reperfusion injury was determined by the slope of the linear regression line modeling the relationship between the duration of intraoperative hepatic ischemia and the peak postoperative transaminase level. Estrogen receptor content was measured in the biopsied liver samples using immunohistochemistry. RESULTS In the whole cohort, the regression slope for aspartate transaminase was comparable between females and males (P=0.940). Within the subgroup of ≤40 y donors, the regression slope was significantly smaller in females (P=0.031), whereas it was comparable within >40 y donors (P=0.867). Within the subgroup of ≤40 y non-macrosteatotic donors, the regression slope was significantly smaller in females in univariable (P=0.002) and multivariable analysis (P=0.006), whereas the sex difference was not found within ≤40 y macrosteatotic donors (P=0.685). Estrogen receptor content was significantly greater in females within ≤40 y non-macrosteatotic donors (P=0.021), whereas it was not different in others of >40 y or with macrosteatosis (P=0.450). CONCLUSIONS The tolerance of hepatic ischemia-reperfusion injury was greater in females than in males only when they were <40 y and without macrosteatosis. The results were in agreement with hepatic estrogen receptor immunohistochemistry study.

Abstract
Using non-drug, non-surgical treatments for improving bone mineral diseases in newborn babies is an important topic for neonatologists. The present study introduces bacterial synthesized ionic nano-hydroxyapatite (Bio-HA) for the development of bone mineral density in the chicken embryo model. In vitro cytotoxicity analyses were demonstrated the optimal concentrations of Bio-HA compared to a chemically-synthesized hydroxyapatite (Ch-HA). Toxicity of Bio-HA on MCF-7 human cell lines was negligible at the concentrations less than 500 μg/mL whereas Ch-HA showed similar results at the concentrations less than 100 μg/mL. Therefore, concentrations at 50 μg/mL and 100 μg/mL were selected for in ovo injection of both materials into the fertilized eggs. The newly hatched chickens were sacrificed in order to monitor their serological factors, total body mass, bone mineral contents and bone mineral density. The results confirmed that Bio-HA increased the average body weight and bone mineral indices of chickens in comparison to the Ch-HA and negative controls (normal saline and intact groups). In view of the intact group, no liver or kidney damage occurred in the groups receiving Bio-HA which promises the effectiveness of these nanoparticles for the treatment of afterbirth bone mineral deficiency.

Impact of intraoperative vascular occlusion during liver surgery on long-term outcomes: A systematic review and meta-analysis. Int J Surg 2017. [PMID: 28645555 DOI: 10.1016/j.ijsu.2017.06.050] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/04/2023]
Abstract
OBJECTIVE To determine the impact of intraoperative vascular occlusion during liver surgery on postoperative long-term outcomes for hepatocellular carcinoma (HCC) patients using a meta-analysis. METHODS A systematic literature search of PubMed, EMBASE, and Cochrane Central was conducted to discover relevant randomized controlled trials (RCTs) and observational studies. Studies that reported postoperative long-term outcomes; 1-, 3-, and 5-year overall survival (OS); and/or 1-, 3-, and 5-year recurrence-free survival (RFS) for both an observation group (vascular occlusion) and a control group (vascular non-occlusion) were included. Forest plots were performed to calculate the difference between the 2 groups. The Q statistic and the I2 index statistic were used to assess heterogeneity. Publication bias was evaluated using Egger's test. RESULTS Four observational studies containing 2917 patients were included in this meta-analysis. The pooled estimation results indicated that intraoperative vascular occlusion would not shorten the postoperative OS (RR = 1.01; 95%CI: 0.98-1.03; P = 0.763) and would not increase the risk of HCC recurrence (RR = 0.99; 95%CI: 0.97-1.02; P = 0.320) with low heterogeneity (I2 = 0.0% and 12.7%, respectively). Furthermore, Egger's test did not reveal any publication bias (P = 0.405 and P = 0.269, respectively) in this research. CONCLUSIONS Intraoperative vascular occlusion during liver surgery is safe for HCC patients. It does not affect the postoperative overall survival or increase the risk of HCC recurrence.
