Ultrasound Real time 2D diagnostics, being an available and non-invasive method, issuccessfully used in human medicine, veterinary medicine and biology to diagnose bothphysiological and pathological conditions. In the case of small animals, the ultrasound is often usedto diagnose gravidity, number, size and vitality of fetuses as well as to diagnose pathologicalconditions present in the genital tract, and is also used to examine testicles and prostate of maleanimals. Today's advanced use of the ultrasound diagnostics provides us with an opportunity todetect numerous pathological conditions of reproductive tract of both female and male animals, andthose conditions directly affect health status of other internal organs. The aim of this study is todiagnose primary genital tract disorders using the ultrasound diagnostics, as well as proving itsconnection to the changes in parenchymal organs. The ultrasound examination was performed onthe total of 12 dogs, 6 male and 6 female dogs. Ovaries, uterus and the organs in the abdominal areawere examined using a transducer ranging from 5 to 8 MHz. A transducer of 7.5 MHz was used toexamine prostates and testicles. The patients were in dorsal position. Three out of six examined maledogs exhibited changes on their prostates, and the remaining one had a tumor on the testicles. Cystitisand hyperplasia of prostate were also found upon the examination of these dogs. One out of sixexamined female dogs, had cystic endometrial hyperplasia, three of them had pyometra, and one ofthem was diagnosed with an follicular cyst. In addition to these pathological conditions, changeswere noticed in the liver and pancreas. Along with the detection of primary changes in the genitaltract of both male and female animals, the ultrasound diagnostics can be used to discover consequentchanges in parenchymal organs.

Aim      To evaluate quantitative and qualitative characteristics of atherosclerotic plaques (ASP) in carotid arteries (CA) and femoral arteries (FA) and to use these data for developing a visual scale (VS) for noninvasive diagnosis and determination of severity of coronary atherosclerosis.Material and methods  This study included 216 patients (115 men and 101 women) aged 24 to 87 years (mean age, 61.5±10.73 years). All patients underwent coronary angiography (CAG) for detecting and determining severity of CA atherosclerosis and duplex scanning (DS) for detecting atherosclerosis of CA and FA.Results Analysis of ultrasound parameters of ASP in CA and FA showed that the maximal ASP height, moderate stenosis and maximal stenosis of the arterial bed had higher predictive values than other ultrasound parameters. These parameters were used for forming diagnostic complexes, on the basis of which two individual VSs for CA and FA were developed. Based on the high prognostic value of both scales, they were combined into one that was named VSCOMB. A ROC analysis determined cut-off points of the VSCOMB for diagnosis of CA atherosclerosis of various severity. VSCOMB scores  >4 indicated pronounced CA atherosclerosis with sensitivity of 86.1 % and specificity of 87.5 % whereas VSCOMB scores  ≤4 excluded it. Thus, VSCOMB score 0–1 indicated the absence of CA atherosclerosis; score 2–4 indicated the presence of subclinical CA atherosclerosis; and score >4 indicated severe CA atherosclerosis.Conclusion      A VSCOMB was developed that includes a set of ultrasound parameters for CA and FA and is useful for noninvasive diagnosis of CA atherosclerosis of various severity. Simple and convenient use of VSCOMB allows it to be used at the screening stage to detect subclinical CA atherosclerosis and to prevent its progression.

Gibbons of the genus Nomascus have a strong sexual dimorphism and dichromatism. As they mature, both sexes develop sex-specific pelage colour. In combination with physical similarities in the genitalia with both sexes, there are problems with determining the sex of young individuals compared to other genus of gibbons. This is a pilot study applying a multiplex polymerase chain reactions based on a non-invasive method for sex determination of gibbons. The study was conducted on 22 faecal samples from gibbons of the genus Nomascus. The animals were monitored by staff so that the samples were identified correctly and each sample was collected immediately after the defecation. Results confirmed the sex in all adult and juvenile animals with known sex; and 2 females and 5 males in juveniles were determined with unknown sex. The results of direct examination completely corresponded with the PCR results. The PCR reaction with template DNA isolated from faecal material required BSA usage, however, we observed the occurrence of nonspecific fragments. This did not affect the reliability of our results and we confirmed the usability of this method for this genus.

Abstract Aims. The prenatal prediction of fetal maturity is very important, since neonatal respiratory distress syndrome (RDS) is one of the biggest causes of neonatal mortality. Our aim was to investigate a new non-invasive method for prediction of fetal maturity and to determine in which group according to gestational age of the fetus, the treatment works the best and in which cases it is necessary to be repeated. Methods. We examined 60 patients (30 with impending preterm delivery, divided in 3 groups: 28-30, 30-32, and 32-34 gestational weeks and 30 controls), at the University Clinic for Gynecology and Obstetrics, Medical Faculty, University “Ss. Cyril and Methodius”, Skopje, R. Macedonia. Fetal maturity was examined using ultrasound histogram from fetal lungs and liver, correlated with gestational age and postpartum RDS. Where possible, we performed amniocentesis for lamellar body count (LBC) to correlate our results with the current invasive method for prediction of fetal maturity. Results. Pre-therapy investigation showed a strong fetal immaturity in 28-32 weeks of gestation and less evident fetal immaturity in 32-34 weeks of gestation. Seventy-two hours post-treatment, fetal maturation was low in the first group, higher in the second and the highest in the third group. Amniocentesis for LBC showed correlation with the ultrasound results. Postpartum results were correlated with pre-delivery ultrasound and showed significance of p <0.05. Conclusion. The results obtained in our study were with high significance, and they were in correlation with other similar studies. However, more extensive investigations should be made to replace the current invasive technique.

Subsurface DNAPL (dense non-aqueous phase liquid) contamination from (un-) intentional spilling typically leads to severe environmental hazards. A large number of studies have demonstrated the relevance of DNAPL source zone geometry for the determination of contaminant plume propagation in groundwater. Optical imaging represents a promising non-invasive method for identifying DNAPL saturation without disturbing multiphase flow dynamics. However, workflow and image analysis methodologies have not been sufficiently developed or described for general application to related experimental efforts. For example, the choice of dye(s) used for phase colorization affects image processing and can bias final estimations of DNAPL saturations. In this study, we perform a series of DNAPL migration and entrapment studies in transparent tanks that are filled with three different types of porous media. Different dyes are used and raw images are acquired. Subsequently, these are used to evaluate a suite of image processing and analysis approaches, which are organized into a workflow. Our approach allows for us to identify key image processing and analysis steps that introduce the most error. Applicable dye configurations led to uncertainties of up to 41% depending on the selection of processing steps. Based on these findings, it was possible to delineate a flexible framework for image processing and analysis that has the potential for transfer and application in other tank experiment setups.
