Abstract

We aimed to investigate the preventive and/or therapeutic effect of berberine on cyclophosphamide-induced

testicular injury. After body weight was measured, a total of 40 rats were randomly divided into 5 groups of 8.

The animals in the control group received oral SF for 14 days. The rats in the CP, ber75, ber150 and ber300

groups were given orally, SF, 75, 150 and 300 mg / kg berberine for 14 days, respectively, and all animals were

injected i.p. 200 mg / kg CP on day 8. 24 hours after the last dose, the animals were weighed again and the

testicular tissues were removed under general anesthesia and then euthanized. After weights were measured,

testicular tissues were used for histological examination, immunohistochemical apoptosis evaluation and

homogenate preparation. Oxidative stress and cytokine levels in testicular homogenate were evaluated. While

CP had no significant effect on body and testicular weights, berberine reduced the body weight in a dose-

dependent manner. Although there was no significant change in oxidative stress markers and cytokine levels,

degenerative changes and apoptotic findings were found in the CP group and these were improved by dose-

dependent treatment with berberine. These effects of berberine may be due to their anti-degenerative and anti-

apoptotic activity rather than being mediated by oxidative stress and inflammation.

In conclusion, our findings suggest that berberine treatment may be useful in the prevention / treatment of CP-

dependent testicular injury.

Abstract

Pancreatic cancer is one of the most aggressive cancer due to the late diagnosis and failure to respond to the

treatment despite advances in tumor biology and the development of new cancer therapeutic strategies. It has

been reported that these characteristics of pancreatic cancer originate from cancer stem cells within the tumor

mass. It has also been reported that the Fentanyl and some other mu-opioid receptors are involved. In this study,

we determined the effect of Fentanyl on PANC-1 cells, by assessing the gene expression of cancer stem cell

marker genes (Nanog, Oct4, and Sox2) and apoptosis-related genes (BAD, Bax, Bcl-2, and p53) by Quantitative

RealTime PCR. The number of cancer stem cells was determined by flow cytometry. The results of our study

showed that Fentanyl administration decreased the number of cancer and cancer stem cells in the PANC-1 cell

population, decreased the gene expression of stem cell marker and increased the expression of apoptosis-related

genes. These results indicate that Fentanyl, which is used routinely in the pain palliation of pancreatic cancer,

can be considered as an option in the treatment of pancreatic cancer.

Abstract

Candidiasis is the most frequently encountered fungal disease that ranges from mild mucosal infections to

serious candidaemia and disseminated candidiasis. There are only limited classes of antifungal agents available

for physicians to combat Candida infections. In addition, biofilm cells display phenotypic traits that resulting in

enhanced resistance to antifungal drugs. Therefore, the limited option to combat fungal threat has raised the

interest in seeking alternative antifungal compounds. The aim of this study was to investigate the antifungal and

anti-biofilm activity of the new Sulfonyl hydrazones compound Anaf-Psh (3-hydroxynaphthalene-

2ethylidenepropane sulfonylhydrazone), derived from sulfonamides. The Candida species evaluated in this

study included the five reference strains and thirty-five clinical isolates belonging to a collection of fungal

strains previously established at the Gazi University Medical Mycology Laboratory. Identification was

performed by conventional methods and by biochemical characterization using the API ID32C® system

(Biomerieux) and was confirmed by the sequencing. The antifungal activity of Anaf-Psh was determined using a

broth microdilution method according to the European Committee on Antimicrobial Susceptibility Testing

(EUCAST) standards. The compound concentrations varied between 0.5–256  µg/ml. The anti-biofilm effect of

the synthesized compound was evaluated in 96-well polystyrene flat-bottom microplates. The compound was

found to be effective against all tested Candida strains with MIC ranging from 8-64 µg/ml and also inhibit

biofilm formation in tested isolates. As a conclusion, it's in vitro antifungal and anti-biofilm properties, this new

compound Anaf-Psh is a promising new agent for the control and treatment of Candida infections.

athletes (age, 18-40 years), using questionnaire. Material and method: Participants (50 males, 57 females)

completed a questionnaire including anthropometric measurements, dietary habits questions and eating attitude

test (EAT-40). The analysis of acquired datas was done using SPSS (version 21.0) and significance for

statistical datas was selected being p<0.05.

Results: The mean BMI of male athletes was 24.1±2,9 kg/m2, while the mean of female athletes was 21.04±2,8

kg/m2 and both groups were within normal BMI ranges. While 58.9% of the athletes stated that they skipped

meals, the most skipped meal was breakfast with 42.9%. It was observed that most athletes consume meat

(%94,4) and dairy products (%96,3). 12.3% of female athletes and 14.0% of male athletes consume sports

drinks; energy drink consumption for male and female athletes is 24.6% and 26.0%, respectively. Most of the

male and female athletes (80.7% and 86.0%, respectively) were not predisposed to eating disorders. There was

no significant relationship between athletes' eating attitude test scores and BMI, body weight, type of sport and

regular breakfast (p>0,05). Conclusion: Having healthy eating habits is very important for athletes to maximize

their performance. Regular education should be given to athletes to gain healthy eating habits and protect them

from eating disorders.

Abstract

The aim of this study was to investigate the effect of different duration treatments of progesterone sponges on

the some reproductive parameters in the Saanen goats at weather conditions of Afyonkarahisar/Turkey. Before

the study, ultrasonography examination was performed for reproductive disorders and total 68 multiparaus and

lactating Saanen goats were selected from herd. In July, intravaginal sponges (Chronogest®) were applicated in

all of groups within the same day for estrus synchronization. Sponges were removed on the days

7th,9th,11th,13th in the groups 1, 2, 3 ,4 respectively (in each group n=17). All group were injected with 480 lU

PMSG (Chronogest-PMSG® i.m) and 125 µg Cloprostenol (Estrumate® i.m) one day before sponge remove

day. At 24 hours after the removal of the sponges, three male goats were placed in each groups for natural

mating. Pregnancy was checked through transrectal ultrasound in dorsal recumbency position on days 25-30

after sponge remove day. The estrus and pregnancy rates were found 82% (14/17), 88% (15/17), 82% (14/17),

81% (13/16) and 57% (8/14), 73%(11/15), 64%(9/14), 53%(7/13) in the groups 1,2,3,4 respectively. Litter size

were found 1,87(15/8), 1,90(21/11), 2,0(18/9) and 1,71(12/7) in the groups. Reproductive parameters were

statistically insignificant between groups. As a result of this study, the synchronization of estrus with this

method did not important change on the reproductive performance in the Saanen goats.

Abstract

This study aimed to determine the popular diet practices and knowledge levels of adult individuals aged

between 18-65 years. The study was conducted with 300 participants (150 males, 150 females) in Istanbul. The

participants' level of knowledge about popular diets and the resources they learned were obtained through a pre-

prepared questionnaire. To evaluate the data, SPSS 22.0 statistical package program was used. It was found that

the average age was 33.2±10.4 years and 50.3% of the participants were normal, 45.7% were overweight and

obese. Popular diets followed by 24% of women, 16.7% of men. It was determined that 91.7% of women and

70.8% of men lost weight with these diets. However, 70.3% of women and 68.8% of men regained weight in the

first 6 months after quitting diet. The weight lost (7.08±5.09 kg) was found to be similar to the weight gained

after quitting diet (7.24±6.7 kg). Participants learned popular diets from internet/social media (25.8%), TV/radio

(24.8%) and their close circle (24.4%). The most well-known popular diets; Karatay diet (24.2%), sugar free

diet (14.7%) and gluten-free diet (12.5%). Popular diets are effective in losing weight in the short term, but do

not contribute to weight management by causing weight gain again in the long term. Incorrect nutrition and diet

practices in weight management should be prevented. Adequate, balanced, healthy nutrition should be provided

with the support of dietician. The negative effects of popular diets should be explained by health professionals

and the community should be raised awareness.

Abstract

The precise aetiology of Digital dermatitis has not been established. However, the rapid spread of disease within

affected herds and a good respond to topical antibacterial suggest that it may have an infectious cause.

Treponemes have been identified in vivo in the lesion and frequently isolated from the lesions and subsequently

cultured in vitro. The role of treponemes in its aetiology still remains uncertain. Fourty biopsies were taken from

dairy cow suffering from digital dermatitis. They placed in 10% buffered neutral formalin solution for

histopathological and spirochaetal immunohistochemical analysis. In immunohistochemical examination,

spirochaetal bacteria were detected in 38 samples. It was observed that these bacteria entered between the

keratinocytes and reached to the pars papillary dermis. They continued to proliferation and stimulate the

inflammatory reaction here. it was found to progress to the deep dermis using lymphatics. Thus, it was observed

that they formed a large and severe inflammatory reaction in the dermis. As a result; It was seen that the agents

reaching the dermis region closest to the epidermis surface by using the epithelial cells that started to be

keratinized from the superficial layer travelled to deeper dermis regions by using lymph vessels. Thus, it was

concluded that a more potent inflammatory reaction and its involvement in circulation could lead to more

complicated events such as septicemia, affect the clinical course and severity of the disease, and especially

localization within lymphatic vessels could be an important mechanism for etiopathogenesis.

SAKARYA UNIVERSITY

Abstract

Herbicides are chemical mixtures used to prevent, control or reduce harmful organisms. These chemicals

especially affect the primary producers that constitute the most important link of the food chain affects the

whole ecosystem. In this context, the impact of such chemicals on algae is extremely important. In this study, in

the C. vulgaris algae exposed to Bentagram, the decrease in OD560 value was observed, while the increase in

the amount of chlorophyll-a was significant for 7 days. There was no significant change on SOD, APX and GR

enzyme activities. An increase in GR enzyme activity was observed only at a concentration of 960 μg mL-1.

MDA and H2O2 amounts are one of the main by-products of lipid peroxidation, which is associated with

oxidative stress in cells. When the total MDA amounts of C. vulgaris cultures were compared due to increasing

concentrations of the Bentagram, a statistically significant decrease was observed in the concentration of only

960 μg mL-1 compared to the control. The total amount of H2O2 did not show statistically significant change

compared to the control. The antioxidant enzyme that determines the accumulation of H2O2 in cells and plays

an important role is APX (Asada, 1992). The amount of free proline decreased significantly at 960 μg mL-1,

which is the highest concentration compared to the control. Increased GR enzyme activity at the same

concentration also supports this information.

As a result, changes in biomass and antioxidant parameters were found to be related to increasing concentrations

of Bentagram.

Abstract

Objective: Extracellular signal-regulated protein kinase (ERK) and c-jun amino-terminal kinase (JNK) are

members of the mitogen-activated protein (MAP) kinase family, ERK is activated by growth factors to stimulate

cell growth, differentiation, and proliferation, while JNK is activated by stress-induced stimuli and mediates

apoptotic signals. It is known that voltage-gated ion channels also play an important role in these cellular

processes. Eag1 (KCNH1, Kv10.1, Ether à go-go), a member of the voltage-gated potassium channel family has

been shown to have oncogenic features and is overexpressed in many human tumors, including breast cancer.

This study aimed to determine the effect of siRNA-mediated silencing of the Eag1 potassium channel on ERK1

and JNK gene expression in strong metastatic MDA-MB-231 cells.

Materials-Methods: ERK1 and JNK gene expressions in Eag1siRNA transfected MDA-MB-231cells were

determined on the Real-Time PCR (qRT-PCR (Stratagene, Mx3000p). Gene expression levels were calculated

using the formula 2−ΔCt = 2−(Ct gen − Ct housekeeping gen).

Results: It was determined that ERK1 expression levels decreased by -1.75 fold and JNK expression level

increases 1.56 fold in Eag1 siRNA transfected MDA-MB-231 cells.

Conclusion: The silencing of the Eag1 gene may alter the signals of proliferation and cell death. Our results

suggest that this gene may be a molecular target in the formation or development of breast cancer and further

research is needed.

EURAC RESEARCH

Abstract

Conflicts and their resolutions among alpine communities represent the process of intensive communication in

local societies, and how conflicts are resolved reflect a Region’s political and social structures. Often conflicts

occur at the interface between traditional, primary activities and new developing economic activities that have a

less environmentally sustainable approach towards natural resources. Nowadays the strain on sharing resources

accelerates the tip-over point towards conflicts. We noted that the presence, return and overabundance of

adaptable species in the Alpine arch, has found many stakeholders and administrators unprepared. Human

presence and expansion in Alpine territories inflict pressure on mobile wildlife species, putting them in the

middle of growing conflicts with humans, often hidden from right view of young generation.

Therefore, the educative process is needed where people wrongly understand wildlife and human activities-

related impact because of a lack of knowledge. However, such approaches are hindered by the family

background of young generation, strongly influenced by household aptitude to wildlife acceptance.

Our analysis identified different human-wildlife interactions in the Alps. The aim of the study is to educate

young generation to be aware of main human-wildlife interactions in order to prevent any conflict and to

provide them as much as possible right information. To meet these challenges, we propose an abstracted and

youthful model that adopts a social-environmental approach to show results have been achieved in interviewing

more than 1000 high school students, coming from different parts of the Alpine arch.

Abstract

Yogurt is among the most common fermented dairy products consumed all over the world. The standardization

of yogurt milk can affect the physicochemical properties of the yogurt which are important acceptance criteria

for consumers. In this study, the aim was to investigate the effect of adding whey protein, inulin and cream to

yogurt milk on the physicochemical characteristics, including the graininess and roughness, of stirred yogurt.

Yogurt milk was standardized by using whey protein, inulin or cream to obtain %15 total solids. The

standardized milk was heated at 72 °C for 15 sec and then, cooled to 42 °C. Cooled milk was inoculated with

yogurt starter culture. After inoculation, the milk was incubated at 42 °C until the pH decreased to 4.60. At the

end of incubation, yogurt samples were manually stirred and stored at 4 °C. The physicochemical properties of

the stirred yogurt samples were analyzed on day 1 of storage. The results showed that the highest viscosity,

hardness, visual roughness, number of grains and perimeter of grains values were obtained in the stirred yogurt

samples produced from standardized milk using whey protein. However, the lowest viscosity, hardness, visual

roughness, number of grains and perimeter of grains values were determined in the stirred yogurt samples

produced from standardized milk using cream. No significant differences (P>0.05) were found in the total dry

matter, pH and titratable values among the stirred yogurt samples produced using whey protein, inulin and

cream.

NAFION–GRAPHENE COMPOSITE FILM MODIFIED GLASSY CARBON

ELECTRODE FOR VOLTAMMETRIC DETERMINATION OF DOPAMINE

ASIYE ASLIHAN AVAN

ISTANBUL UNIVERSITY-CERRAHPAŞA

Abstract

A Nafion–graphene (Nafion–GR) nanocomposite film modified glassy carbon electrode was fabricated by a

simple drop_casting method, and used in the electrochemical detection of dopamine(DA). Owing to the large

surface area, good conductivity of GR and good affinity of Nafion, the sensor exhibited excellent

electrocatalytic activity for the oxidation of DA. The electrochemical behaviors of DA on Nafion/GR film

modified glassy carbon electrodes were investigated by cyclic voltammetry and differential pulse voltammetry.

A calibration curve is constructed in the same matrix, urine, as the unknown samples to be analyzed. The

Nafion–GR film modified electrode was linearly dependent on the DA concentration and the linear analytical

curve was obtained in the ranges of 0.5–200 μM with differential pulse voltammetry (DPV) and the detection

limit was 0.051 μM. The Nafion_graphene nanocomposite modified electrode exhibited good reusability than

pure graphene-modified GCE. This procedure can be used for the determination of DA in the presence of UA,

AA, and TRP. Finally, the proposed method was successfully used to determine DA in urine samples and

pharmaceutical preparations.

Abstract

During the adolescent period, healthy nutrition provides the nutrients necessary for the physical, cognitive

growth and development of individuals and reduces the risk of feeding-related diseases at the beginning of

adulthood. Throughout life, despite the change in body perception, especially adolescence is a period in which

body perception and nutrition problems are experienced. In this age group, the desire to reach the ideal body

size determined by the society, changes on the diet and wrong diet practices may cause inadequate and

unbalanced nutrition. This study was conducted in order to examine the effects of exam anxiety and body

perception on feeding behaviors in adolescents. 203 female and 97 male, in total 300 students whose ages from

17 to 19 participated in the study. General information, exam anxiety, body perceptions and eating behaviors of

the participants were measured using a questionnaire prepared in advance. Test Anxiety Scale, Netherlands

Eating Behavior Survey, Body Appreciation Scale have been applied to the adolescents. When exam anxiety of

the students was examined, physical reaction were found to be higher in girls, mental reaction were higher in

boys (p<0,05). It was found that girls received significantly higher scores than boys in restrictive eating and

emotional eating categories when the participants examined their eating behavior (p<0,05). It was found that

obese individuals scored the lowest in restrictive eating behavior and the highest in emotional eating behavior

(p<0,05). It has been observed that there is positive and significant relation between restrictive eating behaviour

and body liking scores (p=0,00, r=0,201). Healthy eating habits are very important for protecting adolescents

from the stress of education, reducing the effects of body perception and coping with stress.
