Purpose: To investigate preoperative and postoperative factors affecting functional success in anatomically successful retinal detachment surgery. Methods: Seventy-five eyes of 75 patients with rhegmatogenous retinal detachment who underwent anatomically successful surgery from 2014 to 2019 with more than 1 year follow-up were included in the study. Demographic characteristics, ocular examination findings, preoperative and postoperative spectral domain optic coherence tomography images were retrospectively evaluated. Results: The mean age was 53.9 ± 17 years (range, 11–85 years). The mean follow-up period was 36.7 ± 16 months (range, 14–72 months). The mean best-corrected visual acuity of the patients before surgery was 1.35 ± 1.24 and at postoperative 12 months was 0.66 ± 0.5 logarithm of the minimum angle of resolution. Patients who were operated in 7 days of visual symptoms onset were found to have better visual acuity at the first and subsequent postoperative exams. Preoperative proliferative vitreoretinopathy, vitreous hemorrhage, and extent of retinal detachment were found to have a negative effect on functional success at 12 months. Regeneration of the outer retinal layers had a positive effect on visual acuity at 12 months but did not significantly increase visual acuity after 12 months. Multivariate analysis showed that preoperative external limiting membrane integrity was significantly associated with better functional outcomes. Conclusions: Early intervention, presence of preoperative external limiting membrane integrity, and restoration of postoperative outer retinal layers positively affected functional success. The presence of preoperative vitreous hemorrhage, preoperative proliferative vitreoretinopathy, and the extent of retinal detachment had a negative effect on prognosis at 12 months.

MHC Class II+ (HLA-DP-like) Cells in the Cow Reproductive Tract: I. Immunolocalization and Distribution of MHC Class II+ Cells in Uterus at Different Phases of the Estrous Cycle

Eren, U.,Sandikci, M.,Kum, S.,Eren, V. Asian Australasian Association of Animal Productio 2008 Animal Bioscience Vol.21 No.1

This study was undertaken to investigate the distribution of major histocompatibility complex class II positive (MHC II+) (HLA-DP-like) cells in the cow uterus (cervix, corpus and cornu uteri) and to compare these cells between the estrus and diestrus phases of the estrous cycle. Twenty-nine multiparous cows were used. Tissue samples from the middle of the cervix, the corpus and the right cornu were taken immediately after slaughter at the estrus or diestrus phase. Streptavidin-biotin peroxidase complex staining was used to detect MHC II+ cells. The number of MHC II+ cells per unit area of tissue was counted using image analysis software under a light microscope. Numerous MHC II+ cells were found in the endometrium (cervix, corpus and cornu uteri) in both estrus and diestrus. MHC II+ cells were found in the surface epithelium of the cervix uteri in diestrus, but in the corpus uteri in both estrus and diestrus and in the cornu uteri in estrus. MHC II+ cells were also found freely in the lumen of the glands and between the gland epithelia of the corpus and cornu uteri in both estrus and diestrus. There were also MHC II+ cells in the connective tissue of the myometrium and perimetrium (outside the endometrium) and around the blood vessels. Endothelial cells were frequently positive for MHC II staining. More MHC II+ cells were found in the endometrium than outside the endometrium in both estrus and diestrus (p<0.001). However, there was no difference in the numbers of positive cells between estrus and diestrus either in the endometrium or outside it. These results are the first evidence for HLA-DP-like MHC II+ cells in the bovine uterus. They indicate that antigen presentation by HLA-DP-like MHC II+ cells of the uterus is not influenced by hormonal status.

Growth and Laying Performance of Japanese Quail Fed Graded Levels of Hazelnut Kernel Oil Meal Incorporated into Diets

Erener, G.,Ozer, A.,Ocak, N. Asian Australasian Association of Animal Productio 2003 Animal Bioscience Vol.16 No.12

Two experiments were conducted to evaluate the effect of substituting different levels of hazelnut kernel oil meal (HKOM) for dehulled soyabean meal (DSBM) in diets for Japanese quail. Five diets in which HKOM was replaced with 0, 25, 50, 75 and 100% of DSBM protein in a growing diet for a 5 week period using 450 Japanese quails of initial age of 1 week and in a layer diet for a 112 days period using 180 Japanese laying quails of initial age of 7 week were examined in experiments 1 and 2, respectively. Hence, treatment groups were: control (0 HKOM), 0.25 HKOM, 0.50 HKOM, 0.75 HKOM and 1HKOM. In the experiment 1, 1 HKOM decreased BWG compared with the 0 HKOM and 0.25 HKOM, while it increased FCR compared with the 0HKOM at day 21 (p<0.05). Compared with the other groups, 0.75 HKOM and 1 HKOM decreased BWG (p<0.01) at day 28. While the FCR of 1 HKOM was higher (p<0.01) than that of 0 HKOM, 0.25 HKOM and 0.50 HKOM, respectively, that of 0.75 HKOM was higher than that of 0 HKOM and 0.25 HKOM diets at day 28. However, at day 42 of age, BWG, FCR and the feed intake (FI) were not affected (p>0.05) by inclusion of HKOM. Mortality rate, carcase yield and liver, heart and gizzard weight (% of body weight) were not affected (p>0.05) by inclusion of HKOM to the diet. In the experiment 2, egg production was decreased (p<0.05) by the 1 HKOM diet compared with the 0.50 HKOM diet. While FCR increased by the 1 HKOM diet compared with the 0.25 HKOM and 0.50 HKOM diets (p<0.05). Feed intake for quails fed with the 0 HKOM diet was higher (p<0.05) than for quails fed with 0.50 HKOM diet. The egg yolk weight for 0 HKOM diet group was lower (p<0.05) than for quails in 1 HKOM diet group. In conclusion, the results indicate that DSBM can be replaced by HKOM in diets for growing and laying Japanese quails. However 50% HKOM has higher laying performance than 100% HKOM in the laying period.

Background: Fungal pneumonia is a common infectious complication of hematological cancer (HC) patients. In this retrospective study, the objective was set to identify the risk factors and outcome of fungal pneumonia in adult HC patients. Materials and Methods: This retrospective study was conducted with adult (>16 years) HC patients from January 2017 and December 2018. Results: During the study period, of 181 patients included 76 were diagnosed with fungal pneumonia. The most common HC was identified as acute myeloid leukaemia (40%). Of the participating patients, 52 (29%) were hematopoietic stem cell transplant (HSCT) recipients. The median age of patients with fungal pneumonia was significantly greater: 57 vs. 48 (odds ratio [OR]: 1.08) and they had longer hospitalization durations (OR: 1.14). Overall, 37 patients (20%) died, and 28-day mortality was significantly greater among patients with fungal pneumonia than without fungal pneumonia (33% vs. 11%). The most significant risk factors for mortality in fungal pneumonia were identified as need of intensive care unit (ICU) (OR: 191.2, P <0.001) and the need of vasopressor support (OR:81.6, P <0.012). ICU-mortality was (88%). Conclusion: Fungal pneumonia is a lethal complication in HC patients. Intensive care need is the most important predictive factor for mortality

Finite strain nonlinear longitudinal vibration of nanorods

Eren, Mehmet,Aydogdu, Metin Techno-Press 2018 Advances in nano research Vol.6 No.4

The nonlinear free vibration of a nanorod subjected to finite strain is investigated. The governing equation of motion in material configuration in terms of displacement is determined. By means of Galerkin method, the Fourier series solutions satisfying some typical boundary conditions are determined. The amplitude-frequency relationship and interaction between the modes are studied. The effects of nonlocal elasticity are shown for different length of nanotubes and nonlocal parameter. The results show that nonlocal effects lead to additional internal modal interaction for nanorod vibrations.

Growth Performance, Meat Quality and Caecal Coliform Bacteria Count of Broiler Chicks Fed Diet with Green Tea Extract

Erener, Guray,Ocak, Nuh,Altop, Aydin,Cankaya, Soner,Aksoy, Hasan Murat,Ozturk, Ergin Asian Australasian Association of Animal Productio 2011 Animal Bioscience Vol.24 No.8

This study was conducted to investigate the effect of dietary green tea extract (GTE) on the performance, carcass and gastrointestinal tract (gut) traits, caecal coliform bacteria count, and pH and color (CIE $L^*$, $a^*$, and $b^*$) values of the breast muscle in broilers. A total number of 600 day-old broilers (Ross 308) was allocated to three treatments with four replicates containing 50 (25 males and 25 females) birds. The dietary treatments consisted of the basal diet as the control (0GTE) and diets with GTE at 0.1 (0.1GTE) or 0.2 (0.2GTE) g/kg. Body weights and the feed intake of broilers were measured at 1, 21 and 42 days, the feed intake was measured for different periods and the feed conversion ratio was calculated accordingly. At 42 day four birds per replicate were slaughtered for the determination of carcass and organ weights, caecal coliform bacteria count, and also quality of the breast muscle. The dietary GTE increased the body weight, feed efficiency, carcass weight and dressing percentage and decreased caecal coliform bacteria count of broilers (p<0.05). The 0GTE broilers consumed (p<0.01) less feed than the 0.1GTE birds in the entire experimental period. The relative abdominal fat weight and gut length of broilers in the 0.2GTE were tended to be lower (p<0.07) than those in the 0GTE group. The breast meat from 0.1GTE birds had a lower pH value when compared to that from 0GTE birds. The 0.1GTE broilers had lighter breast meat than 0GTE and 0.2GTE birds. The dietary GTE increased $a^*$ and $b^*$ values of the breast meat. Thus this product appeared to have a measurable impact on CIE color values of the breast meat in broilers. The results of the present study may indicate that the improved production results in the group with added GTE are directly connected with physiological mechanisms such as the regulation of the caecal micro-flora.

Feeding Turkey Poults with Starter Feed and Whole Wheat or Maize in Free Choice Feeding System: Its Effects on Their Performances

Erener, G.,Ocak, N.,Garipoglu, A.V.,Sahin, A.,Ozturk, E. Asian Australasian Association of Animal Productio 2006 Animal Bioscience Vol.19 No.1

This study was carried out to determine the effects of free choice feeding of starter feed and whole cereals on the growth of turkey poults. Two hundred-seventy poults (7-d old) were divided into 3 treatment groups each with 3 replications containing 15 males and 15 females. Control poults (C) were fed only on starter feed (280 g CP and 11.7 MJ ME/kg). Treatments for choice-fed turkey poults were offered a choice of a starter feed and wheat (120 g CP and 12.3 MJ ME/kg) for wheat selecting (WS) or maize (83 g CP and 13.9 MJ ME/kg) for maize selecting (MS) group in separate feeders. Final live weight (2,280.7 g for the C vs. 2,374.3 and 2,324.6 g for the WS and MS), daily gain (39.21 g vs. 40.87 and 39.99 g) and total feed intake (95.2 g vs. 103.2 and 97.9 g) in the WS poults were significantly higher (p<0.05) than those of the C group, but feed conversion ratio was not significantly different between the treatments. The proportional intakes of cereals vs. total feed intake were 11% in both the WS and MS group. The amount of protein intake in the C group (280 g CP/kg diet) was significantly (p<0.05) higher than that in WS and MS groups (263 and 259 g CP/kg diet, respectively) whilst the ME intake in the C group (11.7 MJ/kg diet) was significantly (p<0.05) lower than that in MS group (11.9 MJ/kg diet). Our results showed that turkey poults fed starter feed and whole wheat in a free choice feeding system have a higher efficiency in terms of daily gain, final live weight, and an economic advantage may be obtained from free choice feeding due to a reduced protein intake and feed cost.

The Repeatability, Reproducibility, and Correlation of the Schirmer Test: A Comparison of Open versus Closed Eye

Eren Ekici,Cagatay Caglar,Esra Ün Akgümüş 대한안과학회 2022 Korean Journal of Ophthalmology Vol.36 No.4

Purpose: To compare the repeatability and reproducibility of the Schirmer test (ST) without anesthesia when the eyes are open (STo) and closed (STc) in previously undiagnosed patients with suggestive symptoms of dry eye. Methods: In a comparative, observational series case study, 31 patients were included in the study. STo and STc were alternately applied for a total of six times. The ST was applied two times with the eyes open (S1) and closed (S2), respectively, by a single ophthalmologist. Then the ST was repeated four times with the eyes open (S3, S5) and closed (S4, S6), respectively, by a single nurse. Results: S1, S3, and S5 were 23.4, 23.7, and 23.3 mm, respectively. S2, S4, and S6 were 14.7, 15.6, and 16.6 mm, respectively. STc scores were found to be statistically lower than the STo’s in general (right: t = 2.033, p = 0.048; left: t = 3.474, p = 0.004). There was no statistically significant difference in the scores of the three tests with open eyes: S1, S3, and S5 (p = 0.462). There was also no statistically significant difference in the scores of the three tests with closed eyes: S2, S4, and S6 (p = 0.05). Conclusions: Our study suggests that although administering the ST with the patient’s eyes open produces higher readings than STc in patients with suggestive symptoms of dry eye, there was an acceptable reliability among tests performed open and closed. Moreover, intraexaminer reliability was higher than interexaminer reliability for both with the eyes open and closed.

CARDAN POSITIONS IN THE LORENTZIAN PLANE

Eren, Kemal,Ersoy, Soley The Honam Mathematical Society 2018 호남수학학술지 Vol.40 No.1

In this paper, we study the instantaneous geometric properties of motion of rigid bodies in the Lorentzian plane. For this purpose we define Lorentzian form of Bottemas instantaneous invariants. In these regards, we obtain the necessary and sufficient condition of a Lorentzian plane to be at Cardan position with respect to these invariants.
