This study was conducted to determine the nutritive value of live yeast culture (RumiSacc, Saccharomyces cerevisiae) and to investigate its effects on milk yield, milk composition and some blood parameters in lactating cows. Six multiparous Holstein cows were allocated to two groups of three cows and assigned randomly to one of two diets in a cross-over experiment. Daily 50 g RumiSacc was top dressed at the p.m. feeding for the treatment group. RumiSacc supplied a high protein and energy with high organic matter digestibility values (83.35%) determined by in vitro enzymatic analysis. Yeast culture supplementation significantly increased milk yield, tended to increase fat yield, protein yield and lactose yield of milk. Methylated fatty acid level of 18:3 (n-3) in milk fat was increased by yeast culture supplementation. The concentrations of methionine, phenyalanine, tyrosine, tryptophan and taurine were significantly increased with dietary inclusion of yeast culture. Live yeast culture supplementation did not affect other performance characteristics, milk quality characteristics and blood parameters. As a conclusion live yeast culture (RumiSacc, Saccharomyces cerevisiae) had high nutritive value and positive effects on milk production and some milk quality characteristics in lactating cows under field conditions.

This experiment was carried out to determine the effects of supplementation of L-carnitine and humic substances alone or in combination in laying hen diets on performance, egg traits and blood parameters. A total of 180 IGH type brown laying hens aged 22 weeks were employed in a completely randomized block design with one control group and three treatment groups. Each group was divided into five replicates as subgroups, each comprising 9 hens. The diets of the first, second and third treatment groups were supplemented with 0.1 g/kg L-carnitine, 1.5 g/kg humic substances (Farmagulator$^{(R)}$ Dry Plus) and 0.1 g/kg L-carnitine+1.5 g/kg humic substances, respectively. The experimental period lasted 18 weeks. Feeding supplemental carnitine, humic substances or carnitine+humic substances resulted in increases in body weight gain (p<0.05). Dietary treatments did not significantly affect daily feed intake, daily metabolizable energy intake, egg production, egg weight, feed efficiency, mortality, egg shape index, egg breaking strength, egg shell thickness, egg albumen index, egg yolk index, egg Haugh unit and the percentages of egg shell, albumen and yolk. Supplementation of humic substances reduced egg yolk cholesterol as mg per g yolk and mg per yolk (p<0.05). Blood serum parameters were not affected by the supplementation of carnitine, humic substances or carnitine+humic substances. The results in this study demonstrated that humic substances supplementation reduced egg cholesterol without adverse effects on performance, egg traits and blood parameters of laying hens. It was concluded that the usage of L-carnitine alone or in combination with humic substances in diets had no beneficial effects in laying hens.

Yalcin, Sakine,Onbasilar, Ilyas,Sehu, Adnan,Yalcin, Suzan Asian Australasian Association of Animal Productio 2007 Animal Bioscience Vol.20 No.6

This study was conducted to study the effects of dietary garlic powder on laying performance, egg traits and blood serum cholesterol level of quails. A total of three hundred quails (Coturnix coturnix japonica) aged nine weeks were used. They were allocated to 3 dietary treatments. Each treatment comprised 5 replicates of 20 quails. The diets were supplemented with 0, 5 and 10 g/kg garlic powder. The experimental period lasted 21 weeks. The addition of garlic powder did not significantly affect body weight, egg production, feed consumption, feed efficiency, egg shell thickness, egg albumen index, egg yolk index and egg Haugh unit. Adding 5 and 10 g/kg garlic powder to the laying quail diets increased egg weight (p<0.01). Egg yolk cholesterol and blood serum cholesterol concentration were reduced with garlic powder supplementation. The results of this study demonstrated that garlic powder addition had a significant cholesterol-reducing effect in serum and egg yolk without adverse effects on performance and egg traits of laying quails.

Yalcin, S.,Onbasilar, E.E.,Onbasilar, I. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.8

This experiment was conducted to determine and compare some characteristics of the meat and carcass of rabbits aged 11 weeks according to sex. In the experiment thirty male and thirty female New Zealand White rabbits were slaughtered. The weights and percentages of cold carcasses, skin with head and limbs, liver, kidney, heart, lung, fore legs, hind legs, breast and ribs, loin and abdominal wall were recorded. The values for carcass length, lumbar circumference, pH in the muscles of Biceps femoris and Longissimus dorsi, meat to bone ratio and cooking loss were also determined. The mean values for cold carcass weight and cold dressing percentage were 832 g and 48.77% in male and 849 g and 48.69% in female, respectively. In this study no significant differences were shown between male and female rabbits in the characteristics of carcass and meat except the value of pH of Longissimus dorsi muscle which was markedly higher in males than that in females meat. Slaughter weight was positively correlated with the weights of carcass, skin with head and limbs, lung, liver, kidney, heart and weights of joints (p<0.01) and dressing percentage (p<0.05).

Yalcin Bayram,Melihcan Sezgic,Percin Karakol,Mehmet Bozkurt,Gaye Taylan Filinte 대한성형외과학회 2019 Archives of Plastic Surgery Vol.46 No.6

Autologous fat injection was first described roughly a century ago and has been used in surgeryever since. In addition to its use in many surgical fields, it is also frequently used for bothaesthetic and reconstructive purposes in breast surgery. Since the application of fat graftingin breast surgery has steadily increased, studies investigating its reliability have simultaneouslybecome increasingly common. Previous studies have reported that the use of fat grafting inbreast surgery is reliable, but some pending questions remain about its routine use. In order touse fat grafts successfully in breast surgery, it is necessary to be familiar with the structureand content of adipose tissue, the efficacy of adipose stem cell-enriched fat grafts, the oncologicalsafety of fat grafts, and the problems that may occur in the radiological follow-up ofpatients who undergo fat grafting procedures. In this literature review, we aim to discuss theuse of fat grafts in breast surgery by investigating these common problems.

The Discovery of Druggable Anti-aging Agents

Gulperi Yalcin,Cheol-Koo Lee 대한노인병학회 2020 Annals of geriatric medicine and research Vol.24 No.4

Caloric restriction (CR) has been shown to extend the lifespan of many species. Research to identify compounds that imitate the results of CR has shown extensions of both lifespan and healthspan via different mechanisms. For example, mechanistic target of rapamycin (mTOR) inhibitors such as rapamycin, phenols, and flavonoids show antioxidant characteristics, while spermidine induces autophagy. Herein, we summarize research progress and proposed mechanisms for the most well-known compounds showing lifespan-extending potential for anti-aging characteristics.

Fatma Yalcin Musri,Hasan Mutlu,Mustafa Karaagac,Melek Karakurt Eryilmaz,Seyda Gunduz,Mehmet Artac 대한위암학회 2016 Journal of gastric cancer Vol.16 No.2

Purpose: The aim of this study was to determine whether surgical resection of the primary tumor contributes to survival in patients with metastatic gastric cancer. Materials and Methods: A total of 288 patients with metastatic gastric cancer from the Akdeniz University, Antalya Training and Research Hospital, and the Meram University of Konya database were retrospectively analyzed. The effect of primary tumor resection on survival of patients with metastatic gastric cancer was investigated using the log-rank test. Kaplan-Meier survival estimates were calculated. Multivariate analysis was performed using Cox proportional hazards regression modeling. Results: The median overall survival was 12.0 months (95% confidence intewrval [CI], 10.4~13.6 months) and 7.8 months (95% CI, 5.5~10.0 months) for patients with and without primary tumor resection, respectively (P<0.001). The median progression-free survival was 8.3 months (95% CI, 7.1~9.5 months) and 6.2 months (95% CI, 5.8~6.7 months) for patients with and without primary tumor resection, respectively (P=0.002). Conclusions: Non-curative gastrectomy in patients with metastatic gastric cancer might increase their survival rate regardless of the occurrence of life-threatening tumor-related complications.

Guler Yalcin,H.Sebnem Duzgun 대한토목학회 2015 KSCE JOURNAL OF CIVIL ENGINEERING Vol.19 No.7

To achieve a sustainable traffic management and sustainable transportation planning in urban areas one of the tools that can be used effectively is Geographic Information Systems. In Turkey Transportation Department under Civil Engineering deals with roads and railways which are open to public such as inner city and outer city traffic arrangements with General Directorate of Security. This paper aims to analyze road traffic accident distribution according to the vehicle types involved in the accidents for urban areas in sample of Osmaniye, Turkey. While chi-square test is used for non-spatial analysis kernel density, nearest neighbor distances and Kfunction analysis are applied to determine the existence of clustering and hotspots. The network statistics are executed through SANET (Spatial Analysis on a NETwork) V4.1 that runs on ArcMap 10 and for better visualization and understanding the analysis 3D analysis are generated in ArcScene 10. It is realized that the accidents involving two-wheeled vehicles have a high percentage in all accidents. Also the possible reasons to use two-wheeled vehicles at a high rate in the city center are searched by Location Quotient Technique. The importance of this study is to use GIS as a management system for accident analysis with statistical analysis methods.

Hasan Yalcin,Ismet Ozturk,Mehmet Hayta,Osman Sagdic,Tuncay Gumus 한국식품영양과학회 2011 Journal of medicinal food Vol.14 No.10

The effect of irradiation (2.5, 4.0, 5.5, and 7.0 kGy) on chemical properties and volatile contents of linseed was investigated. Consistent decreases were observed in both protein and oil content of the irradiated linseed samples with increasing irradiation doses. The ash content of the irradiated linseed samples increased significantly (P<.05) with increasing irradiation doses except for 5.5 kGy. Irradiation treatment caused irregular changes in palmitic and stearic acid content. Although styrene and p-xylene content decreased as a result of irradiation, 1-hexanol content only decreased at 7.0 kGy. Benzaldehyde, p-cymene, and nonanol were not determined at irradiation doses above 4.0 kGy
