The results were statistically processed by: means of the multivariate variant analysis. It was obtained the following: researched kinematic and gonimetric parameters differ statistically in a significant manner depending on the success of the free throw technique in basketball

Morfološki deformiteti usnog aparata roda chironomus (diptera: chironomidae) izazvani teškim metalima

U slatkovodnim ekosistemima larve Chironomidae su izložene svim prisutnim toksičnim materijama u vodi i sedimentu i kao takve mogu se koristiti kao idealni biotest organizmi. Kod larvi hironomida često se razvijaju deformacije usnih delova, posebno mentuma, za koje se pretpostavlja da su uglavnom prouzrokovani neorganskim hemikalijama. Kod gajenih hironomida (Chironomus) na sedimentu iz šaranskog ribnjaka utvrđen je stepen i tip deformiteta u zavisnosti od koncentracije i tipa teških metala. Larve Chironomus-a (prikupljene iz Jelenačkog potoka) bile su izložene olovo (II) acetat-3 hidratu i bakar (II) sulfat-pentahidratu u koncentracijama 30, 120 i 200 µg/g suve mase sedimenta. Za procenu stepena deformiteta korišćen je indeks toksičnosti TSI po Lenatu. Kod larvi Chironomus-a, izloženih olovu primećen je porast učestalosti deformiteta sa povećanjem koncentracija i to najčešće deformitet medijalno-lateralnih zuba, koji su kraći, i nedostatak zuba. Larve Chironomus-a izložene bakru pokazuju pad stope deformiteta od najniže ka najvišoj koncentarciji, a najčešći tipovi deformiteta su kraći i podeljeni medijalni zubi i kraći medijalno-lateralni zubi

Larve chironomus plumosus (diptera, insecta) izvor esencijalnih masnih kiselina za ishranu šaranske mlađi

U cilju ispitivanja koliko su larve Chironomus plumosus-a pogodne za ishranu gajenih slatkovodnih riba, pre svega šarana, ižvršena je analiza hemijskog i masnokiselinskog sastava larvi koje su prikupljene na kraju tromesečnog perioda gajenja šaranske mlađi u dva eksperimentalna ribnjačka bazena u Centru za ribarstvo i primenjenu hidrobiologiju Poljoprivrednog fakulteta Univerziteta u Beogradu. Udeo sirovih proteina u larvama Chironomus plumosus-a iznosio je 6,61 u jezeru L1 odnosno 6,18% u jezeru L2, što predstavlja vrednost adekvatnu za rast svih slatkovodnih vrsta riba. Sadržaj lipida bio je 0,49 odnosno 0,73%, što je energetski povoljno za sve ribe koje žive u toplim vodama. Prirodnu hranu (larve Chironomus plumosus) karakteriše i visok sadržaj vode: 88,95 u L1 i 89,62% u L2, a što ih čini pogodnom za ishranu šaranske malađi. Lipidnu frakciju larvi Chironomidae u jezeru L1 je činilo 45.36% zasićenih i 53.96 nezasićenih masnih kiselina. U lipidnoj frakciji larvi Chironomidae iz jezera L2 nađeno je 53.47% zasićenih i 46.42% nezasićenih masnih kiselina. Od polinezasićenih (esencijalnih) masnih kiselina nađenih u hironomidama u jezeru L1, najveći deo je pripadao ω-6 linolnoj kiselini (21,37%), zatim ω-3 linolenskoj (3,21%) i eikozopentanskoj ω-3 kiselini (1,27%). Sadržaj linolne kiseline u larvama Chironomidae iz jezera L2 je bio niži i iznosio je 9,78%, eikozopentanska ω-3 kiselina je zastupljena sa 0,45%, a sadržaj linoleinske kiseline je bio viši i iznosio 7,78%. Nedostatak PUFA sa 22 C atoma je verovatno povezan sa slabom enzimatskom sposobnošću larvi Chironomidae za sintezu ovih kiselna iz njihovih prekursora PUFA sa 18 C atoma. Izmerena količina ω-3 i ω-6 masnih kiselina u larvama Chironomus plumosus je iznosila 0,21 u L1, a u jezeru L2 0,81, zadovoljava nutritivne zahteve šarana

Short communication: Pepino mosaic virus, a new threat for Serbia’s tomatoes

Aim of study: To report the occurrence of Pepino mosaic virus (PepMV) on tomato in Serbia and to genetically characterize Serbian PepMV isolates.Area of study: Tomato samples showing virus-like symptoms were collected in the Bogojevce locality (Jablanica District, Serbia).Material and methods: Collected tomato samples were assayed by DAS-ELISA using antisera against eight economically important or quarantine tomato viruses. Three selected isolates of naturally infected tomato plants were mechanically transmitted to tomato ‘Novosadski jabučar’ seedlings. For confirmation of PepMV infection, RT-PCR was performed using specific primers PepMV TGB F/PepMV UTR R. Maximum-likelihood phylogenetic tree was constructed with 47 complete CP gene sequences of PepMV to determine the genetic relationship of Serbian PepMV isolates with those from other parts of the world.Main results: The results of DAS-ELISA indicated the presence of PepMV in all tested samples. Mechanically inoculated ‘Novosadski jabučar’ seedlings expressed yellow spots and light and dark green patches, bubbling, and curled leaves. All tested tomato plants were RT-PCR positive for the presence of PepMV. The CP sequence analysis revealed that the Serbian PepMV isolates were completely identical among themselves and shared the highest nucleotide identity of 95.1% (99.2% aa identity) with isolate from Spain (FJ263341). Phylogenetic analysis showed clustering of the Serbian PepMV isolates into CH2 strain, but they formed separate subgroup within CH2 strain.Research highlights: This is the first data of the presence of PepMV in protected tomato production in Serbia. Considering increased incidence and rapid spread in Europe, the presence of PepMV on tomato could therefore represent serious threat to this valuable crop in Serbia

Plasmopara obducens – nova pretnja proizvodnji Impatiens walleriana u Srbiji

During 2010, Impatiens walleriana plants with symptoms of downy mildew were collected in a greenhouse in the vicinity of Mionica, Kolubara District. Disease incidence was extremely high, approaching 100%, and wilting and collapse of affected plants was very rapid, resulting in losses of more than 90%. White downy growth produced on the lower leaf surface consisted of hyaline, thin–walled sporangiophores with monopodial branching and numerous, ovoid and hyaline sporangia. Apical branchlets of sporangiophores were at right angles to the main axis, with no apical thickening. Pathogenicity tests included inoculation of young I. walleriana plants by spraying with a sporangial suspension, and downy mildew symptoms were observed after 13 to 15 days. The absence of well–defined spots on the infected impatiens leaves and straight sporangiophores indicated that the pathogen was P. obducens, which was further supported by molecular identification, the 5’–end of the nuclear DNA coding for the large ribosomal subunit (LSU rDNA) was amplified by PCR, using primers NL1 and NL4. A representative isolate, 28–10, was sequenced and phylogenetic analysis showed its grouping with other P. obducens isolates of different origin. Considering that impatiens downy mildew in Serbia is proved to be caused by P. obducens it is necessary to employ adequate phytosanitary measures to prevent further spread of the pathogen.Tokom 2010. godine biljke Impatiens walleriana sa simptomima plamenjače sakupljene su u stakleniku u okolini Mionice, Kolubarski okrug. Učestalost oboljenja bila je izuzetno visoka, blizu 100%, a sušenje i propadanje zaraženih biljaka veoma brzo, što je dovelo do šteta većih od 90%. Bela prevlaka patogena koja se razvijala na naličju listova sastojala se od hijalinskih monopodijalno razgranatih sporangiofora sa tankim zidovima i brojnih, ovoidnih i hijalinskih sporangija. Vrhovi grana sporangiofora granali su se pod pravim uglom u odnosu na glavnu osu, bez vršnog zadebljanja. Testovi patogenosti uključili su inokulacije mladih biljaka I. walleriana prskanjem suspenzijom sporangija, a simptomi plamenjače razvili su se nakon 13-15 dana. Odsustvo definisanih pega na zaraženim listovima impatiensa i prisustvo pravih sporangiofora ukazalo je da je prouzrokovač P. obducens, što je dalje potvrđeno molekularnom identifikacijom. Primenom lančane reakcije polimeraze (polymerase chain reaction, PCR), pomoću prajmera NL1 i NL4, umnožen je kodirajući 5’-kraj DNA velike ribozomalne podjedinice (LSU rDNA). Amplifikovani produkt odabranog izolata 28-10 je sekvencioniran, a filogenetske analize pokazale su njegovo grupisanje sa ostalim izolatima P. obducens različitog porekla. Uzimajući u obzir da je ovim istraživanjima dokazano da je prouzrokovač plamenjače na Impatiens walleriana u Srbiji P. obducens, neophodno je preduzimanje odgovarajućih fitosanitarnih mera u cilju sprečavanja daljeg širenja patogena u našoj zemlji

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Attitudes towards a Pulmonic Ingressive "Yes" in English

This paper investigates the attitudes which may be assigned to an irregular form of phonation that appears in the English language. The unusual manner of vocalization involves the pulmonic airstream mechanism to produce pulmonic ingressive (PI) speech. The reverse phonation (RP) is used as a paralinguistic signal (PS) with discourse markers. Clarke and Melchers (2005) typify the token by providing a discourse analysis of its previous uses in communities in Canada, Iceland, Norway, Scotland and Sweden. This paper examines the token, which now appears in English used in the Netherlands, and its reception amongst people who encounter it

Solo harp performance has gained a tendency towards playing solo piano works on harp. Because of the different technical properties of the two instruments, hence the different way of playing, each individual piano piece requires new solution and cannot solely rely on some previously established universal instruction regarding this matter. My master thesis consists analysis of Chopin Preludes Op. 28, the analysis that focuses on examining the methods of adjusting elements of musical text for the harp, which can range from the possibility of literal transcribing, to unavoidable deviations from the original due to the technical impossibility of playing the exact musical text
