BACKGROUND: BK polyomavirus (BKPyV)-associated nephropathy (PyVAN) is a significant cause of premature renal transplant failure. High-level BKPyV viremia is predictive for PyVAN, however, low-level BKPyV viremia does not necessarily exclude the presence of PyVAN. As data are limited whether or not low-level BKPyV viremia has an effect on intermediate-term graft outcome, this study analyzes the impact of low-level BKPyV viremia on intermediate-term graft function and outcome compared to high-level viremia and non-viremic patients...

Kihyuck Choi, Stephen M Marek
Phoma medicaginis (syn. Ascochyta medicaginicola Qchen &L. Cai) causes spring black stem and leaf spot, an important disease of alfalfa and annual medics. P. medicaginis forms uninucleate conidia in melanized pycnidia and is genetically tractable using Agrobacterium mediated transformation (ATMT), resulting in random integration of T-DNA that occasionally generates pycnidial mutants. The T-DNA tagged mutant, P265 displayed smaller pycnidia and more aerial hyphae than the wild type. A single T-DNA disrupted a putative noncanonical poly(A) RNA polymerase gene, Pmncpap1, which in yeast interacts with ribonucleotide reductase (RNR)...

Background The risk of cardiovascular disease is closely connected to adipose tissue inflammation. The links between cardiovascular risk predictors and pro and anti-inflammatory macrophages in human adipose tissue were analysed to gain an insight into the pathophysiology of cardiovascular disease. Design Subcutaneous and visceral adipose tissues were obtained from 79 subjects, 52 living kidney donors (during nephrectomy) and 27 patients with peripheral artery disease (during arterial tree reconstruction). Methods Macrophage subsets were isolated from adipose tissues and analysed by flow cytometry using CD14, CD16, CD36 and CD163 monoclonal antibodies...

BACKGROUND: LMTM is being developed as a treatment for AD based on inhibition of tau aggregation. OBJECTIVES: To examine the efficacy of LMTM as monotherapy in non-randomized cohort analyses as modified primary outcomes in an 18-month Phase III trial in mild AD. METHODS: Mild AD patients (n = 800) were randomly assigned to 100 mg twice a day or 4 mg twice a day. Prior to unblinding, the Statistical Analysis Plan was revised to compare the 100 mg twice a day as monotherapy subgroup (n = 79) versus 4 mg twice a day as randomized (n = 396), and 4 mg twice a day as monotherapy (n = 76) versus 4 mg twice a day as add-on therapy (n = 297), with strong control of family-wise type I error...

BACKGROUND: Fractures of the proximal femur in elderly patients are a challenge for orthopedics, anesthe-sio-logy and geriatrics. Early mobilization reduces postoperative mortality among these patients. Effective anal-gesia is necessary to achieve this goal. MATERIAL AND METHODS: A retrospective analysis of perioperative medical records of 78. patients undergoing surgical treatment of proximal femur fractures was performed. Group 1 (n=35)consisted of patients who were treated with pharmacologic analgesia only (systemic analgesics) and Group 2 (n=43) involved patients who re-ceived a preoperative fascia iliaca compartment block (FICB) and pharmacologic analgesia...

The objective was to investigate combined effects of aging-, freezing-, thawing- treatments on the water-holding capacity, Warner-Bratzler shear force (WBSF) and sensory properties of beef. Semitendinosus muscles from two crossbreeds were analysed. Carcasses were conventionally aged (4days post mortem), muscles were separated and divided into samples. Part of the samples were frozen without wet-aging and the others were wet-aged for 3 or 6days (and then also frozen). Two freezing methods (conventional and cryogenic) and two thawing methods (at 4°C and 20°C) were applied...

REVIEW
Marek Kosmulski
The pristine points of zero charge (PZC) and isoelectric points (IEP) of metal oxides and IEP of other materials from the recent literature, and a few older results (overlooked in previous searches) are summarized. This study is an update of the previous compilations by the same author [Surface Charging and Points of Zero Charge, CRC, Boca Raton, 2009; J. Colloid Interface Sci. 337 (2009) 439; 353 (2011) 1; 426 (2014) 209]. The field has been very active, but most PZC and IEP are reported for materials, which are very well-documented already (silica, alumina, titania, iron oxides)...

Virulence determines the impact a pathogen has on the fitness of its host, yet current understanding of the evolutionary origins and causes of virulence of many pathogens is surprisingly incomplete. Here, we explore the evolution of Marek's disease virus (MDV), a herpesvirus commonly afflicting chickens and rarely other avian species. The history of MDV in the 20th century represents an important case study in the evolution of virulence. The severity of MDV infection in chickens has been rising steadily since the adoption of intensive farming techniques and vaccination programs in the 1950s and 1970s, respectively...

We report non-chiral amino acid residues cis- and trans-1,4-diaminocyclohexane-1-carboxylic acid (cyclo-ornithine, cO) that exhibit unprecedented stereospecific control of backbone dissociations of singly charged peptide cations and hydrogen-rich cation radicals produced by electron-transfer dissociation (ETD). Upon collision-induced dissociation (CID) in the slow heating regime, peptide cations containing trans-cO residues undergo facile backbone cleavages of amide bonds C-terminal to trans-cO. In contrast, peptides with cis-cO residues undergo dissociations at several amide bonds along the peptide ion backbone...

Melatonin is involved in the regulation of carbohydrate metabolism and induction of cold tolerance in plants. The objective of this study was to investigate the roles of melatonin in modulation of carbon assimilation of wild type wheat and the Chl b-deficient mutant ANK32B in response to elevated CO2 concentration ([CO2 ]) and the transgenerational effects of application of exogenous melatonin (hereafter identified as melatonin priming) on the cold tolerance in offspring. The results showed that the melatonin priming enhanced the carbon assimilation in ANK32B under elevated [CO2 ], via boosting the activities of ATPase and sucrose synthesis and maintaining a relatively higher level of total chlorophyll concentration in leaves...

Uncertainty remains regarding the magnitude of effectiveness of influenza vaccines for preventing serious outcomes, especially among young children. We estimated vaccine effectiveness (VE) against laboratory-confirmed influenza hospitalizations among children aged 6-59 months. We used the test-negative design in hospitalized children in Ontario, Canada during the 2010-11 to 2013-14 influenza seasons. We used logistic regression models adjusted for age, season, and time within season to calculate VE estimates by vaccination status (full vs...

We assessed the antibiotic resistance and genetic diversity of 27 Enterococcus faecalis isolates from 25 wild bird species in Poland. Resistance to lincomycin (100%) was most common followed by tetracycline (48%), erythromycin (44%), and ciprofloxacin (22%). High-level resistance to streptomycin and kanamycin was observed in 19 and 15% of isolates, respectively. One isolate (4%) exhibited low-level resistance to penicillin and vancomycin, and all isolates were susceptible to gentamicin and chloramphenicol. Antibiotic resistance was linked to the tet(M), tet(L), erm(A), erm(B), msr(A/B), ant(6)-Ia, and aph(3')-IIIa genes...

The implication of guanine-rich DNA sequences in biologically important roles such as telomerase dysfunction and the regulation of gene expression has prompted the search for structure-specific G-quadruplex agents for targeted diagnostic and therapeutic applications. To date, the number of two-photon absorbing fluorogenic dyes with intrinsically large two-photon absorption (TPA) cross-section (σ2) and quantum yield (φf), capable of specific detection of G-motifs over duplex DNAs is still limited. Herein, we report on a NIR two-photon poly(cationic) anthracene-based macromolecule able to selectively target G-quadruplexes (G4s) over genomic double-stranded DNA...
