Abstract:
Background: Tumor-targeting bacteriophages can be used as a versatile new platform for the delivery of diagnostic imaging agents and therapeutic cargo. This became possible due to the development of viral capsid modification method. Earlier in our laboratory and using phage display technology, phages to malignant breast cancer cells MDA-MB 231 were obtained. The goal of this study was the optimization of phage modification and the assessment of the effect of the latter on the efficiency of phage particle penetration into MDA-MB 231 cells. Methods: In this work, we used several methods, such as

SUMMARYPlasmids in selected type strains of 26 of the Salmonella enteritidis phage types have been characterized by restriction enzyme fingerprinting and by DNA–DNA hybridization with oligonucleotide probes for Salmonella plasmid virulence (Spv) genes. With one exception, the fingerprints of the 38 MDa plasmids studied were homogeneous but there was heterogeneity in the fingerprints of 59 MDa plasmids found in 4 of the type strains. However all 38 MDa and 59 MDa plasmids were related as was a 45 MDa plasmid identified in the type strain of phage type 19. A 3·5 kb fragment homologous to SpvC wa

Abstract:
ABSTRACT Horizontal gene transfer constitutes an important force in prokaryotic genome evolution, and it is well-known that plasmids are vehicles for DNA transfer. Chromosomal DNA is frequently exchanged between pathogenic and commensal neisseriae, but relatively little is known about plasmid diversity and prevalence among these nasopharyngeal inhabitants. We investigated the plasmid contents of 18 Neisseria lactamica isolates and 20 nasopharyngeal Neisseria meningitidis isolates. Of 18 N. lactamica strains, 9 harbored one or more plasmids, whereas only one N. meningitidis isolate contained a

Klebsiella pneumoniae is a nosocomial pathogen. Among its virulence factors is the capsule with a prominent role in defense and biofilm formation. Bacteriophages (phages) can evoke the lysis of bacterial cells. Due to the mode of action of their polysaccharide depolymerase enzymes, phages are typically specific for one bacterial strain and its capsule type. In this study, we characterized a bacteriophage against the capsule-defective mutant of the nosocomial K. pneumoniae 52145 strain, which lacks K2 capsule. The phage showed a relatively narrow host range but evoked lysis on a few strains wit

Abstract:
AbstractThe myelodysplastic syndrome-myeloproliferative neoplasms (MDS/MPNs) are a heterogeneous group of hematologic malignancies characterized by dysplastic and myeloproliferative clinical, laboratory, and morphological overlapping features, both in marrow and in blood. MDS/MPNs include chronic myelomonocytic leukemia (CMML), MDS/MPN with neutrophilia, MDS/MPN with SF3B1 mutation (in its absence with ringed sideroblasts) and thrombocytosis (MDS/MPN-SF3B1-T), and MDS/MPN not otherwise specified (MDS/MPN-NOS). Prognosis of MDS/MPN is highly variable, being dismal in the majority of patients with CMML, MDS/MPN with neutrophilia and MDS/MPN-NOS. In the absence of disease-modifying treatment options, allo-HCT represents the only curative option for eligible patients. With regard to allo-HCT indication in CMML patient, a number of prognostic systems have been developed over the years. As far as pre-transplant phase, in high-risk patients with MDS/MPN and low blast count (&lt;10%), upfront transplantation is the most frequently preferred strategy. In patients with high blast count, pre-transplant treatment with HMAs, or combination of HMAs with other new agents in clinical trials may be considered. In case of rising leukocytosis and/or organ infiltration, hydroxyurea is the drug of choice. In MDS/MPN patients, the choice of conditioning regimen depends on many different conditions, the major ones being comorbidities, patient age, disease phase at transplant, type of donor, and HSC source. In general, myeloablative regimens may be advisable in young patients without comorbidities aiming to reduce the relapse risk, while reduced-intensity regimens are preferred for patients with older age or comorbidities. As disease recurrence represents the major cause of transplant failure in MDS/MPN, there is a growing interest toward possible post-transplant treatment strategies, both as preemptive and as prophylactic modalities.

Abstract:
Abstract This chapter provides an overview of the early, rather unknown, phase of MDMA as a recreational drug. MDMA was first detected by scientists in a forensic laboratory in 1970, and then a few more times up until 1976. A previously unknown document of the United States DEA has been used to describe these early detections. The evidence shows that up until 1976, the distribution of MDMA was rather limited and MDMA was initially produced as a ‘legal alternative for MDA’, which had been scheduled in 1970. Mention is made of a 1970 science fiction novel by the prominent writer Stanislav Lem, which seemed to describe the effects of MDMA, as well as of new documentation suggesting that the American drug chemist Alexander Shulgin had synthesized MDMA in 1975. A description of the American drug guru Timothy Leary’s first experiences with MDMA in 1978 is also given. There were two ‘hotspots’ for MDMA use during the 1970s: initially in the Midwest, and from 1976 onwards in Oregon and California.

Abstract:
Salmonella Kentucky ST198 (S. Kentucky ST198) is the most ubiquitous multidrug resistant (MDR) strain posing the greatest threat to public health, livestock and food industry in Africa. The reinvention of bacteriophage (Phage) as a non-antibiotic alternative only gives a glimmer of hope in the control of MDR strains of Salmonellae. S. Kentucky ST198 posses’ chromosomal and plasmid factors capable of been co-opted into phage mediated transduction and co-transduction of antibiotic resistance genes (ARGs) as well as cross-serovar transduction of ARGs. Phage DT104, DT120 and P-22 like prophages like PDT17 and ES18 together have been shown to be capable of transducing and co-transducing the classical ACSSuT resistance phenotype identified in most S. Kentucky ST198 strain on the continent. Also, the institution of fluoroquinolones and third generation cephalosporin for salmonellosis treatment in animals or human infected by S. Kentucky ST198 strain resistant to these drugs can induce Salmonella phage transduction of kanamycin between different Salmonella serovars if present. This review highlights possible risk associated with the use of known Salmonella phages in the control of S. Kentucky ST198 and the need for chromosomal and plasmid tracking of genes prior to the institution of phage therapy on the continent.

This chapter discusses common methods used for the treatment of MDR, i.e., major antibiotics used for the treatment of MDR bacteria and synergistic approaches by the combination of different antibiotics. Along with common treatments used against MDR bacteria, this chapter also discusses current treatments like anti microbial peptides, anti-virulence compounds, phage therapy and drug repurposing approaches for MDR treatment.

Abstract:
Abstract For many years multiple isomorphous replaccement (MIR) has been the method of choice for phase determination. In most cases MIR is reliable, but occasionally it fails: heavy-atom binding may not occur, or if it does it may lead to loss of isomorphism. Use of Multiwavelength Anomalous Dispersion (MAD) has been introduced to circumvent these two problems (I, 2). On the one hand, the MAD method exploits the presence of anomalous scatterers, such as Cu or Fe in metalloproteins, or any of the heavy-metal derivatizing agents. On the other hand, all measurement relevant to determining a single phase can be made on the same crystal o isomorphism is exact, and electron density maps are of very high quality (3, 4). Thus, the MAD method will likely become a preferred method for phase determination.

Abstract This paper aims at making an overall comparison based on life-cycle costs (LCC) between vacuum degassing and membrane deaeration, the two main technologies for removing oxygen from injection water in the energy upstream sector. Traditional degassing technology based on vacuum towers (VT), where oxygen is stripped from liquid water falling on random packing under vacuum conditions, has been compared with membrane deaeration (MDA), a potentially emerging technology in which oxygen moves from the liquid phase through a gas-permeable membrane toward an oxygen-depleted gas stream.

Abstract:
A new design method, the maximized amplitude difference (MAD) method, is developed to improve the discrimination of binary phase-only filters (BPOFs). In this approach, we construct an energy function that represents the weighted difference between the amplitude of the autocorrelation peak caused by the target signal and that of the cross-correlation peak caused by the nontarget signal. The weight determines the suppression level of the crosscorrelation peak. The best phases for each of the two peaks are determined through a fast deterministic search algorithm.
