Ultrazvučna procjena debljine bedrene hrskavice u bolesnica sa sindromom policističnih jajnika

The aim of the study was to investigate knee cartilage thickness in polycystic ovary syndrome (PCOS) patients using ultrasonography and to assess the effects of sex steroids on osteoarthritis development. A total of 90 female patients were enrolled in the study, including 47 patients diagnosed with PCOS as study group and 43 patients admitted to our hospital for any other complaints as control group. Ultrasonographic evaluation of both knees was performed in all patients. The knee cartilage thickness was measured at lateral condyle, intercondylar area and medial condyle. The measurements were averaged for each region. The mean femoral cartilage thickness was greater in the study group compared with control group in all regions, with a statistically significant difference (p<0.005). In conclusion, we found PCOS patients to have greater mean cartilage thickness, supporting the possible effects of sex steroids on osteoarthritis development.Cilj istraživanja bio je ultrazvučno procijeniti debljinu hrskavice koljena u bolesnica sa sindromom policističnih jajnika (SPCJ) i učinak spolnih hormona na razvoj osteoartritisa. U istraživanje je bilo uključeno ukupno 90 žena, tj. 47 bolesnica s dijagnozom SPCJ kao ispitna skupina i 43 bolesnice primljene na odjel zbog drugih tegoba kao kontrolna skupina. Ultrazvučna procjena obaju koljena učinjena je u svih bolesnica. Debljina hrskavice koljena mjerena je u lateralnom kondilu, interkondilarnom području i medijalnom kondilu te je izračunat prosjek mjerenja za svaku regiju. Srednja debljina koljenske hrskavice bila je veća u ispitnoj skupini u usporedbi s kontrolnom skupinom u svim regijama, a razlika je bila statistički značajna (p<0,005). Dakle, utvrđeno je da bolesnice sa SPCJ imaju veću srednju debljinu koljenske hrskavice, što govori u prilog mogućeg utjecaja spolnih hormona na razvoj osteoartritisa

Effects of Apple Vinegar Addition on Aerobic Deterioration of Fermented High Moisture Maize Using Infrared Thermography as an Indicator

This study was carried out to determine the effects of apple vinegar and sodium diacetate addition on the aerobic stability of fermented high moisture maize grain (HMM) silage after opening. In the study, the effect of three different levels (0%, 0.5% and 1%) of apple vinegar (AV) and sodium diacetate (SDA) supplementation to fermented HMM at two different storage conditions (27–29?C, 48% Humidity; 35–37?C, 26% Humidity) were investigated. The material of the study was fermented rolled maize grain with 62% moisture content stored for about 120 days. Silage samples were subjected to aerobic stability test with three replicates for each treatment group. Wendee and microbiological analyses were made at 0, 2, 4, 7, and 12 days. Meanwhile, samples were displayed in the T200 IR brand thermal camera. According to the thermogram results, 1% SDA addition positively affected HMM silages at the second and fourth days of aerobic stability at both storage conditions (p &lt; 0.05). Aerobic stability and infrared thermography analysis indicated that 1% AV, 0.5%, and 1% SDA additions to HMM silages had promising effects. Due to our results, we concluded that thermal camera images might be used as an alternative quality indicator for silages in laboratory conditions. © 2022 by the authors.

Gaseous ozone application on microbial properties of broiler feeds

Ozone is generally used for preservation and disinfection in many different areas, especially in the food, chemical industry, and health sector due to decompose into oxygen and leave no residue. In this study, the impacts of ozone application on the microbiological of commercially produced broiler feeds were investigated. For this purpose, Aspergillus niger NRRL 326 was introduced into the starter, grower, and finisher diets. Then the effects of gaseous ozone application at different doses (0.9 and 5.6 g h?1) and durations (15 and 30 min) were investigated. A. niger and total mould-yeast numbers were decreased in the feed samples as a result of the ozone application and statistically, a significant difference was found (p &lt;.05). In this study, ozone dose, duration, and their interactions were found to be effective on the decrease of mould-yeast counts in all treated broiler feeds. However, the effect of ozone was higher on pelleted form feeds (grower and finisher). It might be concluded that the disinfection properties of ozone can change according to the physical and chemical structure of feed material and the surface area which contact with ozone.Highlights Ozone application can result in a moderate reduction in A. niger and total mould-yeast counts The most reduction on microbial load was observed in the feed applicated with 5.6 g h?1 gaseous ozone for 30 min. Ozone treatment might be useful to preserve and extend the shelf-life of broiler feeds Ozone efficiency also depends on the contact surface of the application area apart from the treatment time and dose. © 2021 The Author(s).

Nutrient Contents of Some Food Industry By-Products and Their Usage Possibilities as Alternative Feed Raw Materials in Animal Nutrition

Feed costs are of great importance for an economically and ecologically sustainable livestock, as they constitute approximately 60-70% of the costs in animal husbandry. As in the whole world, price increases were observed in feed raw materials depending on the supply-demand balance and pandemic conditions in our country, and this situation was also reflected in feed prices. For example, when the prices of broiler and egg feeds were analyzed between January and November 2021, an increase of 59.7% and 62.6% was observed, respectively. Feed mixes are prepared and fed in order to meet the daily nutritional needs of animals in an optimum way and at minimum cost. In order to meet this need, the research of alternative feed raw materials and their use in rations have been researched for many years. With this study, it was aimed to determine the nutritional composition of the processing by-products (rice broken, bean broken, chickpea broken, lentil broken, lentil bran, corn mix, bulgur bran, sub-semolina by-products) of food production factories and to reveal the possibilities of their use as alternative feed raw materials in animal nutrition. In addition, up-to-date data on the feed industry in Turkey were presented, and the importance of the orientation to alternative feed raw materials in terms of economy, product diversity and sustainability in Turkey and in the world was emphasized. Crude cellulose (HS) ratio of lentil bran, which is one of the under-sieve products, was found to be the highest numerically with 20.6%, followed by bulgur bran (12.7%). However, NDF and ADF contents were also found to be numerically high. Crude protein values were found to be the highest numerically in legume products (21.83%), beans (20.58%) and lentils (24.15%) among the processed residues. In addition, it will be useful to determine the usage rates in the ration, taking into account the anti-nutritional properties of each product

MRI of pneumonia in immunocompromised patients: comparison with CT

PURPOSE:Pneumonia is an important cause of mortality and morbidity in immunocompromised patients. Computed tomography (CT) is the most sensitive imaging modality for the diagnosis and surveillance of these patients. Since CT exposes the patient to ionizing radiation, we investigated the utility of magnetic resonance imaging (MRI) in the diagnosis and surveillance of immunocompromised patients with pneumonia.METHODS:The study included 40 immunocompromised patients with pneumonia documented on CT. The patients were examined by MRI within 48 hours of CT examination. All images were obtained with three different sequences: balanced fast field echo, T1-weighted turbo spin-echo (TSE), and T2-weighted TSE. Lung abnormalities were evaluated using CT and MRI.RESULTS:Infection was determined in 36 patients (90%), while the causative organism remained unknown in four patients (10%). In all the patients, the CT findings were consistent with infection, although three patients showed no abnormal findings on MRI. CT was superior to MRI in the detection of the tree-in-bud nodules, centrilobular nodules, and halo sign (P 20 mm nodules (к=0.844, P < 0.001).CONCLUSION:Although CT is superior to MRI in the diagnosis of pneumonia in immunocompromised patients, MRI is an important imaging modality that can be used, particularly in the follow-up of these patients, thus decreasing to avoid ionizing radiation exposure

Tannins and Their Impacts on Animal Nutrition

Tanenler; bitkilerin yapısında doğal olarak bulunan, kendilerini patojen mikroorganizmalara ve virüslere karşı korumak için ürettikleri fenolik bileşiklerdir. Hayvan besleme açısından ise tanenler; hayvanın türü, fizyolojik durumu, tanenin yapısı ve miktarına bağlı olarak olumlu ve olumsuz etkilere sebep olabilmektedirler. Bu çalışmanın amacı; tanenler, etkileri ve hayvan beslemede kullanımları ile ilgili bir derleme sunmaktır.Tannins are phenolic metabolites, which naturally produced by plants. They can defend plants against pathogen microorganisms and viruses. According to animal nutrition, tannins have both adverse and beneficial effects depending on animal species, physiological state of the animal, structure and concentration of the tannins. The objective of this study was to review the literature about tannins, their effects and usage of tannins in animal nutrition

Effects of Propolis Extract Coating on Shelf Life and Quality Parameters of Eggs Obtained from Free-Range Hens

The study was carried out to demonstrate the effects of the use of water-extracted propolis (PE) as a coating material on shelf life, storage temperature, time, and egg quality parameters obtained from free-range laying hens. The idea of coating an egg with a product to preserve its freshness for a longer time has been the subject of research by researchers. For this purpose, there are studies using samples of propolis extracted using different alcohols. In this study, the effects of coating eggs obtained from free-range reared chickens with water extracted PE and keeping them in different storage conditions on the internal and external quality parameters of the eggs were investigated. For this purpose, 80 eggs were collected from 64-week-old Lohmann brown layers. Egg samples were divided into groups of 8 treatments [2 storage times (10 and 20 days) x 2 storage temperatures (4 degrees C and 22 degrees C) x propolis coating on the shell (coated/uncoated)] and arranged to contain 10 eggs per treatment. In the study, it was seen that PE caused positive effects on the shelf life and internal quality characteristics of eggs stored at room and refrigerator temperature, as it covers the pores on the shell. As a result of coating with propolis extract, specific gravity and egg yolk index values increased (P <0.05). In addition, the number of mesophilic bacteria has decreased. Due to these positive effects, propolis can be considered as a natural alternative product that can be used for eggshell coating. It was determined at the end of the research that coating with the water-derived extract of propolis, a by-product of beekeeping activities, might have positive effects on long-term storage

Quantitative evaluation of ischemic myocardial scar tissue by unenhanced T1 mapping using 3.0 Tesla MR scanner

PURPOSEWe aimed to use a noninvasive method for quantifying T1 values of chronic myocardial infarction scar by cardiac magnetic resonance imaging (MRI), and determine its diagnostic performance.MATERIALS AND METHODSWe performed cardiac MRI on 29 consecutive patients with known coronary artery disease (CAD) on 3.0 Tesla MRI scanner. An unenhanced T1 mapping technique was used to calculate T1 relaxation time of myocardial scar tissue, and its diagnostic performance was evaluated. Chronic scar tissue was identified by delayed contrast-enhancement (DE) MRI and T2-weighted images. Sensitivity, specificity, and accuracy values were calculated for T1 mapping using DE images as the gold standard.RESULTSFour hundred and forty-two segments were analyzed in 26 patients. While myocardial chronic scar was demonstrated in 45 segments on DE images, T1 mapping MRI showed a chronic scar area in 54 segments. T1 relaxation time was higher in chronic scar tissue, compared with remote areas (1314±98 ms vs. 1099±90 ms, P < 0.001). Therefore, increased T1 values were shown in areas of myocardium colocalized with areas of DE and normal signal on T2-weighted images. There was a significant correlation between T1 mapping and DE images in evaluation of myocardial wall injury extent (P < 0.05). We calculated sensitivity, specificity, and accuracy as 95.5%, 97%, and 96%, respectively.CONCLUSIONThe results of the present study reveal that T1 mapping MRI combined with T2-weighted images might be a feasible imaging modality for detecting chronic myocardial infarction scar tissue

Effects of essential oils and vitamin e supplementation on gut microbiology and oxidative stability of broiler meat

Aromatik yağlar veya bitki ekstraktları son yıllarda rapor edilen antioksidan ve antibakteriyel etkileriyle 2006 yılı başına kadar büyütme faktörü olarak kullanılan antibiyotiklerin yerine geçme potansiyeli olan yem katkılarıdır. Bu çalışmada, aromatik yağların (üzüm çekirdeği yağı, kişniş yağı ve defne yaprağı yağı) ve E vitamini ilavesinin etlik piliçlerde performans, et kalitesi ve raf ömrü üzerine olan etkileri araştırılmıştır. Bu amaçla 5 muameleden oluşacak şekilde deneme düzenlenmiştir. Muamele grupları; 1) Kontrol, 2) Üzüm çekirdeği yağı (200 mg/kg), 3) Defne yaprağı yağı (200 mg/kg), 4) Kişniş yağı (200 mg/kg), 5) E Vitamini (200 mg/kg)' dir. Her muamelenin 7 tekerrürü olup, her kafes bölmesine 5 adet bir günlük erkek civciv konularak toplam 175 etlik civciv kullanılmıştır. 42. günde deneme ünitelerinden rastgele alınan birer hayvan üzerinde, göğüs etinin raf ömrü, depolama süresi ve oksidatif stabilitesi, karaciğer ve kalpte ise Malondialdehid (MDA) analizi yapılmıştır. Ayrıca, bağırsak mikrobiyolojisine ve histomorfolojisine ilişkin parametreler için; 21 ve 42 günlük yaşlarda her bölmeden bir hayvan rastgele seçilen hayvanlardan bağırsak doku ve içeriği alınmıştır. İleum ve sekum içeriğinde maya, Enterobakteri spp., laktik asit bakteri ve koliform grubu bakteri sayımları yapılmıştır. Denemedeki performans sonuçları incelendiğinde 21 günlük yaşta bir farklılık gözlenmezken, 42 günlük yaşta en düşük Yem Dönüşüm Oranı (YDO) E vitamini tüketen gruplarda görülmüştür (P0.05), the highest SOD activities exposed in the vitamin E supplemented groups (P<0.05). Besides, the results of the research indicate that SOD enzyme activities were increased with the age of broiler. Feeding the laurel leaves oil increased villus height, crypt depth and decreased lamina muscularis mucosae at the age of 21 d (P<0.05). However, this positive effect did not continue at the age of 42 d. In conclusion, as vitamin E supplementation had positive effects on the performance, ileum microflora of grape seed oil supplemented groups changed for the benefit of non-pathogenic bacteria, due to the decrease in pH levels of ileum. At the same age, LAB, Enterobacteriaceae and coliform counts were found lower for all the treatments than the control groups. Competition for nutrients between host and microorganisms might affect host negatively, so decrease in the cecum microorganism counts would be thought as a positive effect. Furthermore, feeding with grape seed oil resulted in a decrease in the total cholesterol levels of breast meat. In addition, laurel leaves oil had a beneficial effect on the ileum histomorphology at the 21 d. These results indicate that the essential oils can improve gut health and product quality. The products that researched show promising effects, however further researches may be useful to understand their effects better
