A Case of Unicornuate Uterus with Atypical Located Hyperstimulated Ovary after in Vitro Fertilization Pre-Embryo Transfer (IVF-ET).

Abstract: The authors describe a case of a congenital Mullerian anomaly, uterus unicornis with missing right fallopian tube. An in Vitro Fertilization Pre-Embryo Transfer (IVF-ET) procedure was done and presently is known that the patient has left fallopian tube and left ovary, two kidneys, and right ovary is missing. No diagnostic laparoscopy and hysteroscopy were done, only hysterosalpingography (HSG) before the IVF procedure. Several days after the follicular puncture of the left ovary the patient was urgently admitted to the hospital for specialized gynaecology in Varna. Transabdominal ultrasonography showed right ovary atypically located immediately next to the liver and with emerging theca-lutein cysts.

New Time Indices for the Operational Reliability Assessment Regarding Electronic Items

Abstract: The new approaches to assessing operational reliability by introducing a new time indices are discussed in this paper. The case study and experimental results are based on real data. A comparative analysis of the classical approach and the proposed approaches as well for assessing the operational reliability is also presented.

Cb1 receptors in the thalamic reticular nucleus during acute immobilization stress of the rat: an immunohistochemical study

Abstract: Cannabinoids and opioids interact in a number of ways that could be therapeutically beneficial. The CB1 receptors are implicated with the endocannabinoid-mediated modulation of stress, pain, visceral sensation, synaptic plasticity in the thalamus via GABAergic signaling. Thalamic reticular nucleus (TRN) is a thin sheet of GABAergic neurons surrounding anterolateral surface of the thalamus. In our immunohistochemical study we demonstrated expression of CB1 immunoreactive neurons in a light microscope during a normal condition and after the acute stress in the rats. We found higher expression of CB 1 immunoreactivity in stressed animals compared with control group. Opioids and cannabinoids have been shown to have analgesic properties and they are considered as drug targets for the treatment of numerous neurological disorders, pain and stress.

Cross-Sectional Associations Between Mothers and Children's Breakfast Routine-The Feel4Diabetes-Study.

Abstract: Positive influences of family members have been associated with a high probability of children's daily breakfast consumption. Therefore, the aim of this study was to scrutinize the association of breakfast routines between mothers and their children. The baseline data of the Feel4Diabetes-study was obtained in 9760 children (49.05% boys)-mother pairs in six European countries. A parental self-reported questionnaire gauging the frequency of breakfast consumption and of breakfast´ foods and beverages consumption was used. Agreement in routines of mothers and their children's breakfast consumption was analyzed in sex-specific crosstabs. The relationship of breakfast routine and food groups' consumption between mothers and their children was assessed with analysis of covariance. The highest proportion of children who always consumed breakfast were those whose mothers always consumed it. Children consuming breakfast regularly had a higher intake of milk or unsweetened dairy products and all kind of cereal products (low fiber and whole-grain) than occasional breakfast consumers (p < 0.05). The strong similarity between mothers and children suggests a transfer of breakfast routine from mothers to their children, as a high proportion of children who usually consume breakfast were from mothers also consuming breakfast. All breakfast foods and beverages consumption frequencies were similar between children and their mothers.

Polychlorinated biphenyls and organ ochlorine pesticides in turbot (Psetta maxima maeotica ) from Bulgarian Black Sea

Abstract: Persistent organochlorine pollutants (POPs) like polychlorinated biphenyls (PCBs) and DDT residues (DDTs) were determined in muscle tissue of turbot (Psetta maxima maeotica). The samples were collected from Black Sea, near cape Kaliakra, during 2007 - 2011. The fifteen congeners of PCBs, p,p`-DDT and its metabolites p,p`-DDE and p,p`-DDD were determined by capillary gas chromatography system with mass spectrometry detection. The Indicator PCBs UPAC 180, 153, 138, 118 were found most frequently and abundantly. The sum of the Indicator PCBs ranged from 3.80 to 13.94 ng/g wet weight and did not exceed the European maximum limit. The values of toxic equivalency (TEQs) of the 6 `dioxin-like` PCBs were calculated in the range from 0.02 to 0.09 pg TEQ/g ww and did not exceed the European limit of 6.5 pg TEQ/g ww. Among the DDTs, only p,p`-DDE and p,p`-DDD were found at levels 14.45 and 5.05 ng/g wet weight, respectively. The levels of PCBs and DDTs in turbot were determined comparable to those found in fish species from other aquatic ecosystems.
