Mating with seminal vesicle-excised male can affect the uterus phospholipid fatty-acids composition during implantation in an experimental mouse model

ABSTRACT Purpose No comprehensive information is available about uterus fatty acid (FA) change during implantation period and possible effects of the seminal vesicle secretion on it. Materials and Methods In this study, we evaluated FA composition of uterus phospholipids during the implantation period in intact and seminal vesicle-excised (SVX) mated female mice. Forty NMRI female mice were divided into control (mated with intact male) and seminal vesicle excised (SVX)-mated (mated with SVX-male) groups. The phospholipid fatty acids composition was monitored during the first five days of pregnancy using gas chromatography and also implantation rate was evaluated on fifth day of pregnancy. Results We found that levels of linoleic acid (LNA) and arachidonic acid (ARA) showed a decreasing trend from the first to the third day of pregnancy and then started to increase on the fourth day and peaked on the fifth day. In contrast, the level of saturated FA (SFA) increased on the second and third day of pregnancy compared to the first (p<0.05) and then decreased on the fourth and fifth. We also found that the seminal vesicle secretion could affect the levels of LNA, ARA, SFA, and PUFA in uterine phospholipids especially on second and third day. Moreover, there was a positive correlation between ARA level and implantation rate in control but not SVX-mated groups. Conclusions It can be concluded that several uterus FA that have important roles in early pregnancy could be affected by seminal vesicle secretion.

[Assessment of plasma and red blood cells fatty acid composition in boys with attention deficit hyperactivity disorder [ADHD]]

Background: Attention deficit hyperactivity disorder [ADHD] is one of the most common mental diseases in children. Fatty acids are important components of nerve cell myelin. Essential fatty acid deficiency leads to behavioral abnormalities similar to nervous disorders, such as ADHD. The purpose of this study was to determine the composition of fatty acids in plasma phospholipids and whole erythrocyte in the ADHD boys

Methods: This is a case-control study in which 36 boys with ADHD and 37 boys without ADHD -aged 6-12 years- were participated. ADHD children were diagnosed with clinical diagnosis and psychiatric questionnaires by a psychiatrist. Then fatty acids of plasma phospholipids and whole erythrocyte were extracted

Results: The mean content of sum of saturated fatty acids [P=0.004] and arachidonic acid [P<0.001] of plasma phospholipids were significantly lower and mean concentrations of oleic acid [P<0.001] and sum of monoenes [P<0.001] were significantly higher in the ADHD group compared to the control one. However in the total RBC, the mean concentrations of stearic acid [P=0.003], arachidonic acid [P=0.04] and alpha-linolenic [P=0.02] acid were significantly lower and the mean content of linoleic acid [P=0.01] was significantly higher in the ADHD group compared to the control one

Conclusion: Fatty acid composition of plasma phospholipids and RBC in the ADHD children differed from that of the non-ADHD children

Assessing the Effect of Oleic Acid on Markers of Hepatocyte Transplantation in Wistar Rat Model of Induced Liver Damage.

Aims: Hepatocyte transplantation is an alternative to liver transplantation for acute liver failure (ALF). Hepatocyte therapy is limited by several factors including limited homing of transplanted cells and liver functional improvement. Since beneficial effects of monounsaturated fatty acids on liver function and metabolism have been reported previously, our aim was to study oleic acid effects on hepatocyte transplantation outcome. Methodology: ALF was induced by acetaminophen (APAP) injection. Hepatocytes were isolated from male rats and transplanted intraperitoneally into female rats (ALF+HT group). Effect of oleic acid was assessed in rats fed an oleic acid rich diet (ALF+HT+OA group). Plasma levels of albumin (ALB), Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) Alkaline phosphatase (ALP) were determined. Detection of Y-chromosome by PCR was used for homing assessment of transplanted hepatocytes. Finally, hematoxylin and eosin staining was used for histopathologic evaluation of liver. Results: APAP injection resulted in an increase in levels of ALT, AST and ALP. ALT level was decreased to normal range only in ALF+HT+OA group. Oleic acid administration lowered the maximum amount of elevated AST levels compared to ALF+HT group. No significant difference was observed between ALF+HT group and ALF+HT+OA group in ALP recovery. Plasma level of ALB was decreased after APAP injection which was only fully retrieved in ALF+HT+OA group. SRY detection by PCR confirmed successful engraftment of transplanted hepatocytes. H&E staining revealed that OA administration lead to an increase in the number of normal hepatocytes and reduced inflammation in the liver. Conclusion: In conclusion, our findings suggest that dietary oleic acid may improve hepatocyte transplantation success via improvement of liver function.
