Ocena pomoloških osobina novijih sorti borovnice (Vaccinium corymbosum L.) pomoću multivarijacione analize
During three years we investigate the main phenological and pomological
properties of four highbush bluebery in Cacak ecological conditions. Results showed
significant variation of properties evaluated among cultivars and years with inconsistent
behavior of cultivars in some seasons. The highest bunch weight and berry number per
bunch had cv. Reka, whereas the lovest valuaes was found in Ozarkblue and Nui,
respectively. The highest berry weight had cvs. Ozarkblue in 2011 and Nui in 2012,
respectivelz, whereas diferences in 2014 were not significant. The highest and similar
soluble solids content had berries of cvs. Ozarkblue and Reka in 2012, and Reka i Duke
in 2014, respectively, whereas differences among cultivars were not significant. The
lowest soluble solids content had cv. Nui. Statisticaly significant correlations among
blueberry properties evaluated were not determined. The prinicipal component analyisi
(PCA) can be served as confidental model for segregation or grouping cultivars with the
most favourable phenological and pomological properties.Tokom tri godine, ispitivane su najznačajnije fenološke i pomološe osobine

IL28B Genetic Variations in Patients with Recurrent Herpes Simplex Keratitis
Background and objectives: Recurrent herpes simplex keratitis (HSK) is the most common cause of corneal blindness in the developed world. A relationship between host gene polymorphisms and the recurrence of herpes simplex virus (HSV) infection has previously been proposed. Thus, the aim of this study was to investigate a potential association between the IL28B host genotype and recurrent HSK. Materials and Methods: Eighty patients older than 18 years of age of both genders with a history of recurrent herpes simplex labialis (HSL) were considered for inclusion. Seventy-five of these patients were found to be seropositive for HSV-1 and were subsequently enrolled in the study. Twenty-four of the enrolled patients also had a history of recurrent HSK associated with severe corneal scarring and visual acuity deterioration. Total DNA was isolated from whole blood samples. A single-nucleotide polymorphism (SNP) rs12979860 near the IL28B gene on chromosome 19 was genotyped. Results: A significant association was observed between recurrent HSK and two SNPs of the IL28B genotype (CCrs12979860 and CTrs12979860, p < 0.01). The variation CCrs12979860 showed a significantly greater association with HSK (16 out of 26 patients) compared with CTrs12979860 (8 out of 34 patients). Conclusion: Seropositive individuals with a history of recurrent HSK are likely to have the CC IL28B genotype. This genotype may be related to incomplete control of the infection and more frequent periodical viral shedding along the first nerve branch of the trigeminal ganglion, which clinically manifests as recurrent herpes keratitis. The clinical manifestation of recurrent HSV-1 infection seems to be influenced by polymorphism of the IL28B genotype
Postodiplostomatoza na ribnjacima i otvorenim vodama
Posthodiplostomatosis is disease of young freshwater fishes of families Cyprinidae and Cobitidae resulting from the infection with metacercaria, developmental stages of Posthodiplostomum cuticola. Metacercaria present as a black cysts located primarly in the skin, in the sub-epidermal tissue and in the fins. The disease caused by P. cuticola in this fish species is detected in Serbian fishponds for the first time, while in natural waters has been present for many years. It is diagnosed in the grass carp (Ctenopharyngodon idella) and the bighead carp (Aristichthys nobilis) in the form of dark discolorations on fins and cysts that measured approximately 1 mm in diameter. Disease resulted in low percentage of survival in fingerlings and fish weight reduction. Posthodiplostomatosis occured in fishponds in which the preventive measures were not implemented, i.e. where the nurseries were not dried up and mechanically cleaned.Postodiplostomatoza je obolenje mlađih kategorija slatkovodnih riba familja Cyprinidae i Cobitidae koje se karakteriše infekcijom metecerkarijama, razvojnim stadijumomm Posthodiplostomum cuticola. Metacercarije su prisutne kao crne ciste locirane prvenstveno u koži, subepidermalnom tkivu i perajima. Obolenje izazvano P. cuticola konstantovano je prvi put na našim ribnjacima, dok je u otvorenim vodama prisutno već duži niz godina. Dijagnostikovano je kod belog amura (Ctenopharyngodon idella) i sivog tolstolobika (Aristichthys nobilis) u vidu promena na perajima u obliku tamnih diskoloracija i cisti veličine oko 1 mm. Kao posledica obolevanja došlo je do redukcije telesne mase mladunaca, kao i smanjenja preživljavanja. Postodiplostomatoza se javlja na ribnjacima gde se ne primrnjuju preventivno-profilaktičke mere, odnosno gde se objekti za uzgoj mladunaca ne isušuju i mehanički ne obrađuju
Hepatitis B Outbreak Among Men Who Have Sex with Men in the Autonomous Province of Vojvodina, Serbia
** From Crossref via Jisc Publications Router.The European Centre for Disease Prevention and Control reported that there were 2896 acute hepatitis B cases in 24 EU/EEA countries in 2013.1 The incidence ranged from 0.1 cases per 100,000 in France and Portugal to 4.3 per 100,000 in Latvia, with a male-to-female ratio of 2.2:1 in EU/EEA countries, and transmission among men who have sex with men (MSM) reported in 9.4% of all cases of acute hepatitis B.1 Some authors consider hepatitis B virus (HBV) infection to be endemic in the MSM population with the incidence 20 times higher in MSM than in the general population worldwide.2 However, data on HBV prevalence among MSM are available for only four EU/EEA countries.3 Six to ten percent of MSM infected with HBV worldwide are co-infected with HIV.4sch_iih5pub4999pub
Thrombotic and bleeding complications in patients with chronic lymphocytic leukemia and severe COVID-19: a study of ERIC, the European Research Initiative on CLL
BACKGROUND: Patients with chronic lymphocytic leukemia (CLL) may be more susceptible to COVID-19 related poor outcomes, including thrombosis and death, due to the advanced age, the presence of comorbidities, and the disease and treatment-related immune deficiency. The aim of this study was to assess the risk of thrombosis and bleeding in patients with CLL affected by severe COVID-19. METHODS: This is a retrospective multicenter study conducted by ERIC, the European Research Initiative on CLL, including patients from 79 centers across 22 countries. Data collection was conducted between April and May 2021. The COVID-19 diagnosis was confirmed by the real-time polymerase chain reaction (RT-PCR) assay for SARS-CoV-2 on nasal or pharyngeal swabs. Severe cases of COVID-19 were defined by hospitalization and the need of oxygen or admission into ICU. Development and type of thrombotic events, presence and severity of bleeding complications were reported during treatment for COVID-19. Bleeding events were classified using ISTH definition. STROBE recommendations were used in order to enhance reporting. RESULTS: A total of 793 patients from 79 centers were included in the study with 593 being hospitalized (74.8%). Among these, 511 were defined as having severe COVID: 162 were admitted to the ICU while 349 received oxygen supplementation outside the ICU. Most patients (90.5%) were receiving thromboprophylaxis. During COVID-19 treatment, 11.1% developed a thromboembolic event, while 5.0% experienced bleeding. Thrombosis developed in 21.6% of patients who were not receiving thromboprophylaxis, in contrast to 10.6% of patients who were on thromboprophylaxis. Bleeding episodes were more frequent in patients receiving intermediate/therapeutic versus prophylactic doses of low-molecular-weight heparin (LWMH) (8.1% vs. 3.8%, respectively) and in elderly. In multivariate analysis, peak D-dimer level and C-reactive protein to albumin ratio were poor prognostic factors for thrombosis occurrence (OR?=?1.022, 95%CI 1.007?1.038 and OR?=?1.025, 95%CI 1.001?1.051, respectively), while thromboprophylaxis use was protective (OR?=?0.199, 95%CI 0.061?0.645). Age and LMWH intermediate/therapeutic dose administration were prognostic factors in multivariate model for bleeding (OR?=?1.062, 95%CI 1.017-1.109 and OR?=?2.438, 95%CI 1.023-5.813, respectively). CONCLUSIONS: Patients with CLL affected by severe COVID-19 are at a high risk of thrombosis if thromboprophylaxis is not used, but also at increased risk of bleeding under the LMWH intermediate/therapeutic dose administration

Elliptic flow of muons from heavy-flavour hadron decays at forward rapidity in Pb-Pb collisions at root s(NN)=2.76TeV
The elliptic flow, v(2), of muons from heavy-flavour hadron decays at forward rapidity (2.5 <y <4) is measured in Pb-Pb collisions at root s(NN)= 2.76TeVwith the ALICE detector at the LHC. The scalar product, two- and four-particle Q cumulants and Lee-Yang zeros methods are used. The dependence of the v(2) of muons from heavy-flavour hadron decays on the collision centrality, in the range 0-40%, and on transverse momentum, p(T), is studied in the interval 3 <p(T)<10 GeV/c. A positive v(2) is observed with the scalar product and two-particle Q cumulants in semi-central collisions (10-20% and 20-40% centrality classes) for the p(T) interval from 3 to about 5GeV/c with a significance larger than 3 sigma, based on the combination of statistical and systematic uncertainties. The v(2) magnitude tends to decrease towards more central collisions and with increasing pT. It becomes compatible with zero in the interval 6 <p(T)<10 GeV/c. The results are compared to models describing the interaction of heavy quarks and open heavy-flavour hadrons with the high-density medium formed in high-energy heavy-ion collisions.
