Purpose. To study biological features of biological potential realization of softneck garlic productivity. Methods. Field, laboratory, statistical and calculation-analytical. Results. The results of studying local and introduced forms of softneck garlic cultivars (samples No. 1, 14, 16, 19, 24, 27) in comparison with varieties (‘Prometei’ (standard) and ‘Liubasha’) in terms of productivity are presented. In the research, field, laboratory and statistical methods were used. The experimental design was a systemic complete block design without replicates. It was found that all, without exception, softneck garlic cultivars have an erectoid type of leaf placement. Introduced cultivars featured low seedstalk formation, which is a manifestation of adaptation to growing conditions. All studied cultivars were characterized by lower values of the number of air bulbils in the inflorescence compared to the standard cultivar ‘Prometei’. Thus, ‘Liubasha’ formed 16.1% fewer bulbils than the standard; however, its 1000-bulbil weight was 37.2% larger than in ‘Prometei’. The softneck cultivars that formed bulbils on the reduced seedstalk were characterized by a very small number of bulbils − by 89.7–90.8% less than in the standard – however, the formed bulbils had very large 1000-bulbil weight. Thus, sample No. 1 formed bulbils by 542.0% larger in terms of the 1000-bulbil weight than standard; sample No. 16 by 554.3%; sample No. 27 by 752.9%. Samples No. 14, 19 and 24 did not formed seedstalks. In terms of the bulbil yield, the samples that formed bulbils had by 11.7–40.1% lower indicators than the standard. Cultivar ‘Liubasha’ was characterized by a 19.0% higher bulbil yield. The vast majority of collection samples of winter garlic formed smaller bulbs. Sample No. 16 had a large bulb wight compared to the standard. Collection samples had significantly lower yield except for No. 16, which exceeded the standard by 30.2 and 56.8%. Conclusions. Collection samples have a significantly higher dry matter content. The promising samples (No. 14, 16, 19, 24) were selected by a number of characteristics as promising for further breding of softneck table garlic cultivars. In further research, the content of secondary metabolites and the storage of the samples in uncontrolled conditions will be studied in order to create table garlic cultivars suitable for long-term storage.

Purpose. Find out the features of biometric indicators formation in sugar beet hybrids of domestic breeding. Methods. Field, laboratory. Results. According to the results of the research, it was determined that in early August, the maximum weight of roots (840 g) was in hybrid ‘ITsB 0904’. Good indicators were observed in hybrids ‘Umanskyi Ch S97’, ‘Soniachnyi’ and ‘Anichka’, 770, 780, and 800 g at the average group indicator of 730 g. It was investigated that the hybrid ‘Maksym’ (15.1%) and ‘Etiud’ (14.9%) were the best in terms of sugar accumulation in roots. Sugar content at the level of 14.8 % was observed in hybrids ‘Umanskyi ChS 97’, ‘Ramzes’, ‘Konstanta’, ‘Soniachnyi’ and ‘Verkhnia’ at the average group value of 14.5%. Conclusions. It is important to continue the study of the dynamics of root and leaf mass formation together with the process of sugar accumulation in roots in terms of establishing individual efficiency of hybrids and developing recommendations for the fullest realization of their potential in production conditions.

The Democratic Republic of the Congo (DRC) declared an Ebola virus disease (EVD) outbreak in North Kivu in August 2018. By June 2019, the outbreak had spread to 26 health zones in northeastern DRC, causing >2,000 reported cases and >1,000 deaths. On June 10, 2019, three members of a Congolese family with EVD-like symptoms traveled to western Uganda’s Kasese District to seek medical care. Shortly thereafter, the Viral Hemorrhagic Fever Surveillance and Laboratory Program (VHF program) at the Uganda Virus Research Institute (UVRI) confirmed that all three patients had EVD. The Ugandan Ministry of Health declared an outbreak of EVD in Uganda’s Kasese District, notified the World Health Organization, and initiated a rapid response to contain the outbreak. As part of this response, UVRI and the United States Centers for Disease Control and Prevention, with the support of Uganda’s Public Health Emergency Operations Center, the Kasese District Health Team, the Superintendent of Bwera General Hospital, the United States Department of Defense’s Makerere University Walter Reed Project, and the United States Mission to Kampala’s Global Health Security Technical Working Group, jointly established an Ebola Field Laboratory in Kasese District at Bwera General Hospital, proximal to an Ebola Treatment Unit (ETU). The laboratory consisted of a rapid containment kit for viral inactivation of patient specimens and a GeneXpert Instrument for performing Xpert Ebola assays. Laboratory staff tested 76 specimens from alert and suspect cases of EVD; the majority were admitted to the ETU (89.3%) and reported recent travel to the DRC (58.9%). Although no EVD cases were detected by the field laboratory, it played an important role in patient management and epidemiological surveillance by providing diagnostic results in <3 hours. The integration of the field laboratory into Uganda’s National VHF Program also enabled patient specimens to be referred to Entebbe for confirmatory EBOV testing and testing for other hemorrhagic fever viruses that circulate in Uganda.

Abstract: Background. The neuroendocrine effect on the hypothalamus-pituitary-adrenal cortex axis is significant example stressor of electromagnetic exposure for biological object. Aim. The neuroendocrine effect investigation of multi-frequency electromagnetic field laboratory animals’ exposure from 2-5 generations cellular base stations Methods. The neuroendocrine status evaluated by corticosterone and adrenocorticotropic hormone (ACTH) concentrations in blood exposed and sham rats. ACTH and corticosterone rat blood assessed by immunoenzyme method. Results. The results of the multi-frequency electromagnetic field laboratory animals’ exposure from 2-5 generations cellular base stations in a chronic experiment showed wave-like changes in the hypothalamic-pituitary-adrenal function. These changes are manifested in an immediate increase in corticosteroids secretion and depression of the corticosteroid response to normal or subnormal levels. After 3 month chronic exposure there was a secondary rise in hormonal secretion.
