PLACE OF ECHOGRAPHY IN SPECIFYING APPROACHES TO TREATING OVARIAN CANCER

The results of ultrasound study and surgical treatment in 248 patients aged 20 to 78 years who had ovarian epithelial malignancies were the subject of this investigation that has provided evidence that ultrasonic tomography is currently the leading imaging technique that allows specification of the ovarian cancer spread pattern and, depending on this, elaboration of adequate treatment policy

Intervention treatments for chronic pain syndrome in cancer patients

Noninvasive treatments for chronic pain syndrome benefit in 80-90% of cancer patients. Invasive, intervention procedures for analgesia should be used in other cases. These include neuroablative and neuromodulatory measures. Neuroablation is defined as the physical suspension of painful impulse transmission pathways by a surgical, chemical, or thermal method and comprises lytic and other blocks. Neuromodulation is the dynamic and functional suppression of pain impulse pathways by the intraspinal or intraventricular administra- tion of opioids and other chemicals

VALUE OF ULTRASONIC TOMOGRAPHY IN THE STAGING OF ENDOMETRIAL CANCER

Based on the results of preoperative examination in 180 patients, the investigators studied and analyzed the specific features of ultra- sonic images of endometrial cancer in detail. The comprehensive study comprising color Doppler and energy mapping, three-dimen- sional echography with standard and variable-frequency transducers was conducted using the expert-class ultrasound equipment. A close analysis revealed the high informative value of complex ultrasonic tomography in the preoperative staging of cancer of the cor- pus uteri, in its early stages in particular

Effect of the Composition of Copolymers Based on Glycidyl Methacrylate and Fluoroalkyl Methacrylates on the Free Energy and Lyophilic Properties of the Modified Surface

This study proposes to use reactive copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates with a low fluorine content in the monomer unit as agents to reduce the surface free energy (SFE). This work reveals the effect of the structure and composition of copolymers on the SFE and water-repellent properties of these coatings. On a smooth surface, coatings based on copolymers of glycidyl methacrylate and fluoroalkyl methacrylates with fluorine atoms in the monomer unit ranging from three to seven are characterized by SFE values in the range from 25 to 13 mN/m, which is comparable to the values for polyhedral oligomeric silsesquioxanes and perfluoroalkyl acrylates. On textured aluminum surfaces, the obtained coatings provide time-stable superhydrophobic properties with contact angles up to 170° and sliding angles up to 2°. The possibility of using copolymers based on glycidyl methacrylate and fluoroalkyl methacrylates for the creation of self-cleaning polymer coatings is shown

Roach (Rutilus rutilus) reproductive cycle: a study of biochemical and histological parameters in a low contaminated site

Fish reproduction is subjected to worrying trends in many aquatic environments. In this study, we report the absence of histological and biochemical alterations in fish sampled in a low contaminated site (characterised by the absence of detectable oestrogenic activity and mutagenicity in sediment extracts). A total of 474 roach (Rutilus rutilus) were monthly sampled during 18 months, and no intersex fish were recorded after careful histological examination, thus indicating that the incidence of this phenomenon may be very low under natural conditions. Furthermore, mean male plasma vitellogenin concentration was 24 ng ml(-1) and was only slightly elevated during the spawning period (up to 120 ng ml(-1)) indicating that these low values may be characteristic of a low contaminated site. Of the male roach, 45.3% were sampled, a sex-ratio that did not significantly deviated from the expected 1:1 ratio between male and female. Results also showed that natural conditions can greatly affect the reproductive cycle of roach. Gametogenesis showed a biphasic pattern with first gonad maturation between September and December and a final maturation occurring at the end of winter/early spring. Under decreasing temperatures, particularly below 6A degrees C, gametogenesis was stopped or even regressed with secondary oocytes becoming rare under histological observation. Conversely, elevated temperatures during the winter lead to an earlier gonad maturation
