![]() Oxidative stress due to ROS has been implicated as a cause for infertility by impairing the antioxidant mechanisms of the cells. Results indicated that supplementing frozen-thawed boar semen with 0.25 mM quercetin improves sperm characteristics up to 10 h after thawing and decreases polyspermy while improving early embryonic development in pigs.Īn imbalance between high levels of oxygen-derived oxidants, often called reactive oxygen species (ROS), and low levels of antioxidants can lead to cells experiencing an oxidative stressed environment which could possibly damage or cause cellular morphological abnormalities. Supplementation of quercetin significantly decreased ( P < 0.05) polyspermy and significantly increased ( P < 0.05) the percentage of embryos reaching blastocyst stage of development by 144 h after IVF compared to no supplementation. There were no differences in penetration rates and male pronucleus formation between treatment groups. Spermatozoa supplemented with 0.25 mM quercetin had significantly higher ( P < 0.05) motility (51.67☘.50 %) and percent of viable cells (61.21 ± 2.44 %) compared to all other treatments at 10 h after thawing, in addition to having significantly ( P < 0.05) lower levels of hydroperoxide (3.38 ± 0.88 μM/10 7cells). Embryos were evaluated for IVF kinetics 12 h after IVF (penetration, polyspermy, male pronucleus formation, IVF efficiency) and cleavage and blastocyst formation at 48 h and 144 h after IVF, respectively. Spermatozoa were evaluated for motility, viability, and membrane lipid peroxidation levels at 0, 2, 4, 6, 8, and 10 h after thawing. The objective of this study was to determine the effects of supplementing quercetin (0.25, 0.50, 0.75 mM) during the thawing and incubation of frozen-thawed boar semen on spermatozoan characteristics, IVF kinetics (n = 400) and subsequent embryonic development (n = 1340). ![]() Antioxidants can be supplemented to reduce the impacts of oxidative stress.

Murtha Piggott but thats the clever thing - it is! choose you search subject and off you go. After installing it, and running it, I 'get' the purpose, and would gladly recommend it Will, Stormfront Tech Allan CampbellĪt first, I was skeptical of the utility of Minitube. Great app! Was hesitant to buy, but it did what it said and was exactly what I was after! James Bedford My dad has even told me that this is without a doubt the program that he spends most of his time on (he does other things, but this is almost constantly open in another space playing some traditional Italian music or 1930s comedies). My 4 years old is a big fan of Minitube -) RobertoĪ clean, modern interface and no requirement of third party plug-ins makes this program an invaluable tool Tomaaato She really LOVES television, so I think she will like using Minitube as Minitube would be a terrific way to introduce her to the world of Internet I will be installing a copy of Minitube om my Mother's PC. Videos more like the experience of watching television, and more enjoyable. I believe you succeeded well in your goal to make watching It's been a long time since I found a program that works out of the box and does what the blurb says it should. It sort of subtly changes your perception of what's going on. Minitube allows you to search for videos in a breeze without any complications in between. It's a terrific app that eliminates the need to poke around YouTube's Web site and navigate through a sea of ads, comments, and related videos you may not care about. Makes it impossible to stop watching videos when what you should be doing is writing that program's review. If you're looking for a way to check out YouTube clips outside the browser, it's a really elegant solution Lifehacker My kids just love this app! Easy to use and a great interface.
