First report of Phytophthora citrophthora causing fruit brown rot of Feijoa in Italy
2019
Feijoa (Feijoa sellowiana) is native to South America. In the early 20th Century it was introduced into Sicily (southern Italy), where it is grown as an ornamental plant and for its fruits. In 1985 a Phytophthora brown rot of feijoa fruits was reported in the province of Syracuse (eastern Sicily) (2). Several species of Phytophthora, including P. citricola, P. citrophthora, and P. nicotianae, were recovered from soil samples taken from trees with infected fruits. These species were experimentally inoculated on detached feijoa fruits and all incited symptoms of brown rot. However, only P. citricola was isolated from naturally infected fruits. In early autumn 1999, an outbreak of Phytophthor…
Effects of Inbreeding, Outbreeding, and Supplemental Pollen on the Reproduction of a Hummingbird-pollinated Clonal Amazonian Herb
2010
Understory herbs are an essential part of tropical rain forests, but little is known about factors limiting their reproduction. Many of these herbs are clonal, patchily distributed, and produce large floral displays of nectar-rich 1-d flowers to attract hummingbird pollinators that may transport pollen over long distances. The aim of this study was to investigate the effects of clonality, cross-proximity, and patchy distribution on the reproduction of the hummingbird-pollinated Amazonian herb Heliconia metallica. We experimentally pollinated flowers within populations with self-pollen and with pollen of different diversity, crossed flowers between populations, and added supplemental pollen …
SELFING ABILITY AND MALE STERILITY IN SENECIO VERNALIS WALDST. ET KIT. (ASTERACEAE) FROM ISRAEL
1994
Two major findings relating to the breeding system of Senecio vernalis from Israel are reported. First, isolation experiments failed to confirm the existence of a widespread, truly self-compatible and predominantly self-pollinating breeding system in Israeli populations of S. vernalis. However, a single S. vernalis plant derived from a natural stand at Jerusalem was found to be self- compatible and strongly self-pollinating. In its progeny, there were signs of inbreeding depression commonly associated with selfed offspring of outbreeding species. Selfing ability ratios in this progeny indicate a single dominant gene for selfing ability in S. vernalis. The implications of these observations …

Polymers with antiviral properties: A brief review.
2021
Viruses that are pathogenic to humans and livestock pose a serious epidemiological threat and challenge the world's population. The SARS-CoV-2/COVID-19 pandemic has made the world aware of the scale of the threat. The surfaces of various materials can be a source of viruses that remain temporarily contagious in the environment. Few polymers have antiviral effects that reduce infectivity or the presence of a virus in the human environment. Some of the effects are due to certain physical properties, e.g., high hydrophobicity. Other materials owe their antiviral activity to a modified physicochemical structure favoring the action on specific virus receptors or on their biochemistry. Current re…
Izlīgums kā pamats personas atbrīvošanai no kriminālatbildības
2015
Izlīgums ļauj cietušajam un likumpārkāpējam atrisināt ar noziedzīgu nodarījumu radušās problēmas mierīgā ceļā bez tiesas iejaukšanās, un tas var būt kā pamats personas atbrīvošanai no kriminālatbildības, tieši tāpēc izlīgums šādā kontekstā ir nozīmīgs abām pusēm, kā arī sabiedrībai kopumā. Šis institūts satur dažādus aspektus gan no saturiskā, gan procesuālā viedokļa, kurus ir svarīgi izpētīt, lai saprastu izlīguma būtību. Darbā tiek izpētīts izlīguma kā pamata personas atbrīvošanai no kriminālatbildības institūts Latvijas krimināltiesībās, pievēršoties institūta vēsturiskajai attīstībai, nozīmei, saturiskajai analīzei, procesa īstenošanai un iespējamām sekām. Darbā tiek izcelti dažādi inst…
Eiropas Cilvēktiesību tiesas ekstrateritoriālā jurisdikcija
2019
Maģistra darbā ietverta informācija par ANO cilvēktiesību līgumu uzraugošo komiteju, kā arī Starptautiskās tiesas prakse ekstrateritoriālas jurisdikcijas noteikšanai efektīvas kontroles un efektu doktrīnas ietvaros. Vienlaikus ir īpaši piešķirta uzmanība pamatprincipiem, kas attīstīti Eiropas Cilvēktiesību tiesas judikatūrā, veicot to plašu analīzi. Teorētiskajā daļā ietverts izvērsts ekstrateritorialitātes vērtējums gan doktrīnā, gan starptautisko lēmējinstitūciju praksē, tās skaidrojums, kā arī ieskats nepieciešamībai nodalīt valsts jurisdikciju no tiesas jurisdikcijas. Praktiskajā daļā apskatīta Eiropas Cilvēktiesību tiesas judikatūras attīstība ekstrateritoriālās jurisdikcijas jautājumā…
Eiropas Cilvēktiesību konvencijas un starptautisko humanitāro tiesību mijiedarbība starptautisku bruņotu konfliktu situācijās
2020
Starptautiski ir atzīts tas, ka starptautiskās cilvēktiesības, tai skaitā Konvencija, savu spēku starptautisku bruņotu konfliktu situācijās automātiski nezaudē. Tomēr šādās situācijās darbojas arī cita starptautisko tiesību nozare – starptautiskās humanitārās tiesības. Bakalaura darbā autore pēta abu nozaru – starptautisko cilvēktiesību un starptautisko humanitāro tiesību – attiecības, īpašu uzmanību pievēršot tieši ECT nostājai attiecībā uz Konvencijas un starptautisko humanitāro tiesību savstarpējām attiecībām. Autore darbā analizē ECT praksi, sniedzot vērtējumu abu nozaru savstarpējo attiecību evolūcijai šajā praksē. Tiek secināts, kuram no principiem, kas raksturo abu nozaru attiecības,…
MRSA ST22-IVa (EMRSA-15 clone) in Palermo, Italy
2010
Summary: Epidemic spread of methicillin-resistant Staphylococcus aureus (MRSA) strains carrying the Staphylococcal Chromosomal Cassettes (SCC) mec type IV is being increasingly reported in many geographical areas. A survey to determine the prevalence and characteristics of MRSA SCCmec IV isolates identified in four general hospitals in Palermo, Italy, was carried out. During the period February–June 2009, SCCmec type IVa has been found in 12 out of 94 isolates. Nine isolates from all hospitals and all strains from a NICU outbreak occurring in the same period were attributed with the ST22-IVa (EMRSA-15) clone. In our setting, due to the changing MRSA epidemiology, detection of SCCmec IV coul…
Epidemic dissemination of Salmonella enterica spp. enterica serovar Bovismorbificans in southern Italy in the years 1989-1991.
1994
Epidemic strains of Salmonella enterica subsp. enterica serovar Bovismorbificans isolated in southern Italy during the years 1989-1991 were submitted to a molecular epidemiological study in comparison with isolates identified in the years 1980-1988 in the same geographic area. Genomic DNA fragments obtained by digestion with BglI or Eco RI hybridized with Escherichia coli rRNA to produce three distinct, but highly related patterns. Ribotype 1, which had never been identified before 1989, was found to characterize most of the strains identified between 1989 and 1991. Such a finding supports the hypothesis of emergence and spread of a new bacterial clone associated with the increased number o…
