A single-mode electromagnetic resonance (SMER) system was developed to achieve ultrafast and uniform rewarming for large samples.

Overall, the SMER system achieved rapid heating at 331.63 ± 8.59°C min^-1 while limiting the maximum thermal gradient to <9°C min^-1, significantly better than the other two warming methods.

Despite the efficiency of sperm cryopreservation, excessive reactive oxygen species (ROS) production during cryopreservation can induce structural and functional changes in spermatozoa. Also, cryopreservation has been shown to decrease the spermatozoa's antioxidant activity inducing them to be more sensitive to damage caused by ROS. Experimental evidence suggests that astaxanthin (AXT) has essential activities such as antioxidant, antibacterial, and antithrombotic properties. Therefore, this study aimed to evaluate the effect of AXT on the sperm quality of healthy men during freezing-thawing. In the first phase, 10 semen samples with different concentrations of AXT (0.0, 0.5, 1, and 2 μM) were cryopreserved to achieve an optimal dose of AXT. Then, motility, viability, and phosphatidylserine (PS) externalization were evaluated. In the second phase, 25 samples were collected and divided into 3 groups: fresh group, control group (untreated frozen-thawed samples), and AXT group (treated frozen-thawed with AXT). Then, samples were cryopreserved in freezing media supplemented with or without the optimal concentration of AXT (1 μM). After thawing, the levels of sperm parameters, including motility (using a computer-assisted sperm analyzer), viability (eosin-nigrosin), early apoptotic change (annexin V/propidium iodide), ROS (flow cytometry), and lipid peroxidation (LPO) (using enzyme-linked immunosorbent assay), were evaluated. Our results showed that the addition of 1 μM AXT to sperm freezing media improved all parameters of sperm motility and viability (<i>p</i> ≤ 0.05). Furthermore, it could reduce the levels of ROS parameters (intracellular hydrogen peroxide and superoxide) compared with the control group (<i>p</i> ≤ 0.05). Also, AXT significantly decreased the level of PS externalization (<i>p</i> ≤ 0.05) and LPO (<i>p</i> ≤ 0.05) after the freezing-thawing process. In conclusion, our findings demonstrated that human semen treatment with 1 μM AXT before the freezing-thawing process has protective effects against oxidative stress and could diminish the destructive effects of this process on sperm quality.</p>","PeriodicalId":49231,"journal":{"name":"Biopreservation and Biobanking","volume":" ","pages":"367-373"},"PeriodicalIF":1.6,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40625228","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are few studies concerning the quality control of DNA extracted from them. Our research aimed to perform quality control of DNA extracted from ACPs after cryopreservation for >10 years. <b><i>Materials and Methods:</i></b> A total of 1377 ACP samples (separated from 3 mL of whole blood) were retrieved from our biobank, where they had been cryopreserved for 10-15 years. Chemagic STAR was used to extract the DNA. Absorbance at A260, A280, and A230 were measured by spectrophotometry, and integrity was analyzed by agarose gel electrophoresis. The quality thresholds for an Illumina Asian Screening Array (ASA) were yields greater than 0.5 μg, concentration of 25-150 ng/μL, A260/280 ratio of 1.6-2.1, and no degradation fragments in the electrophoresis gel. <b><i>Results:</i></b> The median yield of genomic DNA was 54.30 μg (interquartile range [IQR] 35.55-74.64).
