    Opis:
    Iğdır Province is situated in the Eastern Anatolian Region of Turkey. Wild edible plants and their utilization methods have not been previously documented there. This study was conducted during an ethnobotanical survey of Iğdır Province from 2007 to 2012, in the period from May to October, when plants were in their flowering and fruiting periods. There were 210 interviews carried out in 78 villages. This study provides information about 154 wild plant taxa belonging to 27 families that have been used as foodstuffs, spices, or hot drinks. Seventeen wild edible plants were recorded for the first time during this study. Eight endemic species were reported as used for their edibility, and new local names for plants were also recorded. The cultural importance index was calculated for each taxon. The most culturally important species are Mentha longifolia, Falcaria vulgaris, Polygonum aviculare, Rosa canina, Crataegus azarolus, Capsella bursa-pastoris, and Malus sylvestris. This study presents the richest heritage in terms of the diversity of wild edible plants ever recorded in Turkey.

    Introduction and Objectives. Nosocomial infections, also known as hospital-acquired infections, has become one of the most important health problems in health care units worldwide. The presented study aims to determine the average amount of microorganism loads and to show that the atmospheres of the two hospitals can be a potential source regarding nosocomial infections. The effect of surface and floor disinfection processes in the two hospitals and the antibiotic susceptibility of the bacterial isolates were also evaluated. Materials and Methods. Microorganisms were isolated from air samples collected from different areas (patient wards, corridors, operating theatres and postoperative units) of the two hospitals in Izmir. Sampling was conducted between December 2006 – March 2007. Results. During the 3-month sampling period, the average number of live microorganisms in the air samples collected from second-class environments in the hospital 1 and the hospital 2 was found to be 224.44 and 536.66 cfu/m3, respectively. The average number of microorganisms in hospital 2 collected before the disinfection process was higher than those after the disinfection process. However, because of the closure of the air-conditioning system and the hepa filters after the disinfection process, this was reversed in hospital 1. In total, 54 and 42 isolates were obtained from hospital 1 and hospital 2, respectively. 49 isolates from hospital 1 and 35 isolates from hospital 2 were identified as Staphylacoccus sp. The remaining isolates were identified as Aerococcus sp. and Enterococcus sp. Pseudomonas sp. was not determined in the air samples of the two hospitals. Conclusions. It was detected that the microbial loads in the atmospheres of the two hospitals studied varied greatly depending on the number of people in the environment. As the results indicate, the total number of microorganisms in the atmospheres of operating theatres in both hospitals does not pose a threat according to the Air Microbe Index.

    Opis:
    The aim of the present study was to determine the effects of Luteolin (LUT) on semen quality, oxidative stress, apoptosis, acrosomal integrity, mitochondrial membrane potential and dead sperm ratio in rabbits. Ejaculates from six New Zealand rabbits were collected, evaluated and pooled. The pooling was divided into five groups as control (no additive) LUT 25 μM, LUT 50 μM, LUT 100 μM and LUT 200 μM and LUT added. It was then filled into a falcon tube with Tris-based extender at a final concentration of approximately 35 x 106 spermatozoa. Diluated rabbit semen samples were drawn into frozen and thawed. Frozen semen straws were thawed at 37°C in 30 seconds. According to our findings, no statistical difference was found between all doses of luteolin and the control group in the CASA (computer assisted sperm analysis) analysis performed at 4°C. However, total motility, progressive motility and rapid sperm percentage were found to be higher in the frozen and thawed rabbit semen at a dose of LUT 50 μM compared to the other groups (p<0.05). While amplitude of lateral head displacement (ALH) and beat cross-frequency (BCF) values were found at the lowest dose of LUT 200 μM, a statistically significant difference was observed between the other groups. When the flow cytometry results were examined, no statistical difference was found between the rate of dead sperm, acrosomal integrity, mitochondrial membrane potential and apoptosis rate. Morever, the H2O2 percentage was found to be lower in all experimental groups compared to the control group (p<0.001). In conclusion, the addition of LUT in long-term storage of rabbit semen provided a protective effect for spermatozoa with its antioxidative properties against damage caused by cryopreservation.

    This study was carried out at Sabuncuoğlu Şerefeddin Vocational School of Health Services, Amasya University. In this study, the relationship between smoking habits and rage and anger of the Vocational School students was examined for identification purposes. Within the scope of this study, the survey was performed to reach 608 out of 822 students in 2015-2016. The youth socioeconomic factors influencing smoking, cultural characteristics, as well as peer influence, emulation, school failure, loneliness, alcohol and drug use, social students' range and anger along with psychological factors, such as stress were analyzed cross-sectionally. The demographic questionnaire used for the data collection, information about smoking habits and the anger-anger scale were used. The independent variables were age, gender, type of school, parents' educational level, parental occupational status, income, and income perception. The reasons for smoking initiation, trying, quitting and continuing to smoke of smokers and non-smokers and anger styles related to these reasons were compared. Consequently, in our study, the smoking habits of males have been found more pronounced when compared to females. However, no significant relationship was found between the smoking habits and the anger-anger style. The age of smoking initiation has been determined to be proportional to the beginning of adolescence. This study will shed light on possibilities of smoking prevention and will facilitate quitting of smoking.

    Opis:
    Clinically significant grapefruit juice-drug interactions are an interesting development in the last ten years of research process in the scope of drug interactions. In 1989 a group of Canadian researchers found incidentally that grapefruit juice, used as a carrier system, interacts with some calcium channel blockers, while applying alcohol during a study on alcohol-drug interactions, and presented it in Lancet as a "short report". In this report it is stated that this effect of grapefruit juice is specific and there is no similar interaction with orange juice. The grapefruit juice interactions with drugs and changes in drug pharmacokinetics, individual responses to grapefruit juice in the relationship between the drug concentration and the effect began to gain a larger clinical significance. Drugs interacting with grapefruit juice are metabolized by cytochrome P450 enzyme system in liver or intestinal section. Flavonoids contained in grapefruit juice inhibit the enzyme, bind as a substrate to the enzyme system and disrupt its bioavailability. Naringin is an essential bioflavonoid in the grapefruit juice. Naringin is not a potent inhibitor of cytochrome P450, but it is partly metabolised to "Naringenin" by intestinal bacteria. This substance is a powerful inhibitor of cytochrome P450 and it is believed by some researchers, that these are components responsible for the effect of grapefruit juice. In 2008 the number of drugs that can cause danger when taken together with grapefruit was 17. It has been reported that this number has risen to 43 in 2012. However, while the research of the possible effects of other not yet identified components of the grapefruit juice is still in progress, FDA has begun to put cautionary statement to many drug prescriptions.

    Opis:
    In this study, gamma shielding properties of concretes containing magnetite and limonite ores at different ratios (5%, 10%, 15%, 20%, and 30%) were investigated by using a 60Co (1.25 MeV) radioactive source which was built in Thratron 1000E™ device used for radiotherapy purposes. Then, the photon transmission values (I/I0) were measured by 0.6 cm3, farmer type, PTW™ ion chamber. The dose readings (I0 and I), made by PTW™ Unidose Electrometer, were used to calculate the linear attenuation coefficient (, cm-1), the mean free path (, cm), and the mass attenuation coefficient (, cm2/g) by the Lambert equations, and the results were compared with the calculations obtained using the WinXCom computer program. The findings from this study revealed that the concretes containing magnetite and limonite ores were more effective than the ordinary concrete in the attenuation of gamma rays. It was determined that the values of the mean free path decreased with the increasing concentrations of magnetite and limonite ores while the linear attenuation coefficients for 10 concrete blocks increased with the increasing magnetite and limonite ore concentrations. A comparison of the theoretical values obtained from the WinXCom computer program and the experimental results revealed a good level of conformity.

    Opis:
    The study aimed to determine the most appropriate irrigation scheduling for mini-type cucumber plants grown as a spring-summer cycle crop. The research was conducted in a greenhouse structure in the fields of the Research Institute in Kirklareli. Marathon cucumber plants were used as the plant material in the trials. The split plot design experimental layout in 3 replications was used in the research. Four different plant–pan coefficients (0.75, 1.00, 1.25 and 1.50) and two irrigation intervals (2 and 4 days) were applied as subplots and main plots of the study, respectively. As a result of the 3-year investigation, it was determined that yields, number of cucumber fruits, and fresh cucumber fruit weight, length and diameter increased with the increase in the irrigation water amount. The highest average total soluble solids (Brix) value of 5.0 was recorded under conditions of most severe stress imposed on the plots with lowest water application rates of Kcp 0.75. While the lowest values of 4.0–4.1 were obtained for plants growing under more favorable moisture conditions in plots with application of Kcp 1.25 and 1.50. Statistically significant positive linear relationships were obtained for irrigation water amount on one hand, and fruit number, fruit mean weight, fruit length and diameter on the other, while the relationship between water applied and TSS (Brix) was negative.

    Opis:
    Pressure injuries are a serious medical problem that both negatively affects the patient's quality of life and results in significant healthcare costs. In cases where a patient doesn’t receive appropriate treatment and care, death may result. Nurses play critical roles in the prevention, care, and treatment of pressure injuries as members of the healthcare team who closely monitor the health status of the patient. Today, the use of artificial intelligence is becoming more prevalent in healthcare, as in many other areas. Artificial intelligence is a method that aims to solve complex problems by using computers to mathematically simulate the way the brain works. In this article, we compile and share information about a deep learning model developed for the detection and classification of pressure injuries. Deep learning can operate on many types of data. Convolutional Neural Networks (CNN) prefer images because they can handle 2D arrays. In this case, the images, annotated according to the National Pressure Injury Advisory Panel pressure injury classification system, have been fed into a deep learning model using CNN. The developed CNN model has a 97% success in detecting and classifying pressure injuries, and as more images are collected and fed into the CNN, the prediction accuracy will increase. This deep learning model allows for the automatic detection and classification of pressure injuries, an indicator of health outcomes, at an early stage and for quick and accurate intervention. In this context, it is expected that the quality of nursing care will increase, the prevalence of pressure injury will decrease, and the economic burden of this health problem will decrease.
    Odleżyny są problemem zdrowotnym, który negatywnie wpływa na jakość życia pacjenta i powoduje poważne koszty opieki. W przypadku braku odpowiedniego leczenia i opieki może to doprowadzić do śmierci pacjenta. Pielęgniarki odgrywają kluczową rolę w zapobieganiu, opiece i leczeniu odleżyn jako członkowie zespołu opieki zdrowotnej, którzy ściśle i stale monitorują stan zdrowia danej osoby. Obecnie w dziedzinie zdrowia, podobnie jak w wielu innych dziedzinach, coraz częściej wykorzystuje się sztuczną inteligencję. Sztuczna inteligencja jest metodą, która ma na celu rozwiązywanie złożonych problemów poprzez matematyczne symulowanie sposobu działania mózgu z wykorzystaniem komputerów. Niniejszy artykuł jest przeglądem zaprojektowanym w celu podzielenia się informacjami na temat modelu deep learning opracowanego do wykrywania i klasyfikacji odleżyn. Deep learning może działać na wielu typach danych. Konwolucyjne sieci neuronowe (ang. convolutional neural networks, CNN) preferują obrazy, ponieważ mogą obsługiwać macierze 2D. Obrazy, uporządkowane zgodnie z systemem klasyfikacji odleżyn według National Pressure Injury Advisory Panel (NPIAP), zostały przekształcone w "Deep Learning Model" z wykorzystaniem CNN. Opracowywany model CNN ma 97% skuteczności w wykrywaniu i klasyfikowaniu odleżyn, a im więcej obrazów zostanie zebranych i wykorzystanych w CNN, tym większe będzie prawdopodobieństwo trafnej prognozy. Ten model deep learning daje możliwość automatycznego wykrywania i klasyfikacji odleżyn, które są wskaźnikiem jakości zdrowia, na wczesnym etapie oraz dokładnej i szybkiej interwencji. W tym kontekście oczekuje się, że jakość opieki pielęgniarskiej wzrośnie, zmniejszy się częstość występowania odleżyn oraz obciążenie ekonomiczne związane z tym problemem zdrowotnym.
