Objective: Effects of linseed oil (LO) supplementation on the fat content and fatty acid profile of breast meat, and the expression of three genes in the liver, breast muscle and fat tissues of commercial 154-day-old hybrid male turkeys were investigated. Methods: The animals in the control group were fed a commercially available feed and received no LO supplementation (n = 70), whereas animals in the LO group (n = 70) were fed the same basic diet supplemented with LO (day 15 to 21, 0.5%; day 22 to 112, 1%). The effect of dietary LO supplementation on fatty acid composition of breast muscle was examined by gas chromatography, and the expression of fatty acid desaturase 2 (FADS2), peroxisome proliferator activated receptor gamma (PPARγ), and insulin-like growth factor 1 (IGF1) genes was analysed by means of quantitative reverse transcription polymerase chain reaction. Results: The LO supplementation affected the fatty acid composition of breast muscle. Hepatic FADS2 levels were considerably lower (p<0.001), while adipose tissue expression was higher (p<0.05) in the control compared to the LO group. The PPARγ expression was lower (p<0.05), whereas IGF1 was higher (p<0.05) in the fat of control animals. There were no significant (p>0.05) differences in FADS2, PPARγ, and IGF1 gene expressions of breast muscle; however, omega-6/omega-3 ratio of breast muscle substantially decreased (p<0.001) in the LO group compared to control. Conclusion: Fatty acid composition of breast meat was positively influenced by LO supplementation without deterioration of fattening parameters. Remarkably, increased FADS2 expression in the liver of LO supplemented animals was associated with a significantly decreased omega-6/omega-3 ratio, providing a potentially healthier meat product for human consumption. Increased PPARγ expression in fat tissue of the LO group was not associated with fat content of muscle, whereas a decreased IGF1 expression in fat tissue was associated with a trend of decreasing fat content in muscle of the experimental LO group.

Hakan Kerem,Ulaş Bali,Erhan Sönmez,Mustafa Kürşat Evrenos 대한성형외과학회 2018 Archives of Plastic Surgery Vol.45 No.2

Background Cranially-based nasolabial flaps are a good alternative for the reconstruction of nasal defects. Methods A cranially-based nasolabial flap was used in 18 patients to reconstruct defects of the nose from 2010 to 2016, and the long-term results are presented in this report. Results Fifteen of the flaps completely survived. All the patients had a bulky appearance, but they did not want to undergo a second operation for cosmesis. The dissection of the flap took approximately 20 minutes, and the total operation lasted for 1 hour. The patients were hospitalized for 1–7 days, and the postoperative follow-up period was 1–28 months (mean, 17 months). Conclusions The cranially-based nasolabial flap possesses all the advantages of the traditional forehead flap, and can safely be used in selected cases.

Enhancing bio-suppression of Parthenium hysterophorus L.: Diapause in Zygogramma bicolorata Pallister and its manipulation through insulin-like peptides (ILPs)

R.K. Gupta,Salil Gupta,K. Bali,K. Srivastava 한국응용곤충학회 2010 Journal of Asia-Pacific Entomology Vol.13 No.4

In-depth investigations on diapause behaviour of Z. bicolorata revealed that the adults entered diapause at any time from August to December and that the number peaked (42.00%) during the last half of November. The percentage of adults entering diapause increased with a decrease in day length. Weight of diapausing adults was significantly higher than weight of non-diapausing adults. The percentage of adults undergoing diapause at 30 °C was significantly lower than those undergoing diapause at 15 and 25 °C. The percentage of adults burrowing increased with increasing moisture. In silty soil and soil with high organic matter, 46.7%and 49.2% of adults entered diapause, respectively, whereas in sandy soil, only 23.5% of adults entered diapause. When newly emerged beetles were exposed to 5 μg of human insulin 30/70, a significantly lower percentage of treated adults underwent diapause compared to untreated adults under both feeding and no feeding conditions. Insulin treatment also influenced the emergence period from diapause (93.92±1.73 days), percent emergence (81±1.54%) and fecundity/month (512.7±25.38 eggs) of Z. bicolorata in treated adults as compared to untreated adults (109.05±2.2, 74.00±1.82 and 438.3±19.33 eggs,respectively). However, there was no significant impact of insulin on adult longevity. These findings are of great utility in the biological suppression of Parthenium as it will enhance the effectiveness of this beetle through manipulation of diapause.

Iron titanium phosphates as high-specific-capacity electrode materials for lithium ion batteries

Essehli, R.,El Bali, B.,Faik, A.,Naji, M.,Benmokhtar, S.,Zhong, Y.R.,Su, L.W.,Zhou, Z.,Kim, J.,Kang, K.,Dusek, M. Elsevier Sequoia 2014 Journal of Alloys and Compounds Vol.585 No.-

Two iron titanium phosphates, Fe<SUB>0.5</SUB>TiOPO<SUB>4</SUB> and Fe<SUB>0.5</SUB>Ti<SUB>2</SUB>(PO<SUB>4</SUB>)<SUB>3</SUB>, were prepared, and their crystal structures and electrochemical performances were compared. The electrochemical measurements of Fe<SUB>0.5</SUB>TiOPO<SUB>4</SUB> as an anode of a lithium ion cell showed that upon the first discharge down to 0.5V, the cell delivered a capacity of 560mAh/g, corresponding to the insertion of 5 Li's per formula unit Fe<SUB>0.5</SUB>TiOPO<SUB>4</SUB>. Ex-situ XRD reveals a gradual evolution of the structure during cycling of the material, with lower crystallinity after the first discharge cycle. By correlating the electrochemical performances with the structural studies, new insights are achieved into the electrochemical behaviour of the Fe<SUB>0.5</SUB>TiOPO<SUB>4</SUB> anode material, suggesting a combination of intercalation and conversion reactions. The Nasicon-type Fe<SUB>0.5</SUB>Ti<SUB>2</SUB>(PO<SUB>4</SUB>)<SUB>3</SUB> consists of a three-dimensional network made of corners and edges sharing [TiO<SUB>6</SUB>] and [FeO<SUB>6</SUB>] octahedra and [PO<SUB>4</SUB>] tetrahedra leading to the formation of trimmers [FeTi<SUB>2</SUB>O<SUB>12</SUB>]. The first discharge of lithium ion cells based on Fe<SUB>0.5</SUB>Ti<SUB>2</SUB>(PO<SUB>4</SUB>)<SUB>3</SUB> materials showed electrochemical activity of Ti<SUP>4+</SUP>/Ti<SUP>3+</SUP> and Fe<SUP>2+</SUP>/Fe<SUP>0</SUP> couples in the 2.5-1V region. Below this voltage, the discharge profiles are typical of phosphate systems where Li<SUB>3</SUB>PO<SUB>4</SUB> is a product of the electrochemical reaction with lithium; moreover, the electrolyte solvent is reduced. An initial capacities as high as 1100mAhg<SUP>-1</SUP> can be obtained at deep discharge. However, there is an irreversible capacity loss in Fe<SUB>0.5</SUB>Ti<SUB>2</SUB>(PO<SUB>4</SUB>)<SUB>3</SUB> due to the occurrence of insulating products as Li<SUB>3</SUB>PO<SUB>4</SUB> and a solid electrolyte interface.
