Metallo-β-lactamase gene blaVIM was identified on the chromosome of four Pseudomonas spp. isolates from a chicken farm, including one P. aeruginosa from swallow (Yanornis martini), one P. putida from fly, and two P. putida from chickens. The four isolates shared two variants of blaVIM-carrying genomic contexts, which resemble the corresponding regions of clinical MBL-producing Pseudomonas species. Our study suggests the surveillance of carbapenemase-producing bacteria in livestock and their surrounding environment is urgently needed...

REVIEW
Maren Schmiester, Ilja Demuth
hSNM1B/Apollo is a member of the highly conserved β-CASP subgroup within the MBL superfamily of proteins. It interacts with several DNA repair proteins and functions within the Fanconi anemia pathway in response to DNA interstrand crosslinks. As a shelterin accessory protein, hSNM1B/Apollo is also vital for the generation and maintenance of telomeric overhangs. In this review, we will summarize studies on hSNM1B/Apollo's function, including its contribution to DNA damage signaling, replication fork maintenance, control of topological stress and telomere protection...

The channel catfish virus (CCV) is a pathogenic herpesvirus that infects channel catfish Ictalurus punctatus in pond aquaculture in the southeastern USA. Mannose-binding lectin (MBL), an innate immune protein, could play an important role in the innate response of channel catfish by binding to CCV. Cell cultures of CCV were grown in channel catfish ovary cells (CCOC). A dot-immunoblot enzyme-linked immunosorbent assay was done to determine the binding ability of 5 mo old channel catfish serum MBL (26.2 µg ml-1) to CCOC infected with CCV...

Monoclonal B-cell lymphocytosis (MBL) is an asymptomatic clinical entity characterized by the proliferation of monoclonal B cells not meeting the diagnosis criteria for chronic lymphocytic leukemia (CLL). MBL may precede the development of CLL, but the molecular mechanisms responsible for disease progression and evolution are not completely known. Telomeres are usually short in CLL and their attrition may contribute to disease evolution. Here, we determined the telomere lengths of CD5+CD19+ cells in MBL, CLL, and healthy volunteers...

IMP-1 type metallo-β-lactamase-producing (MBL-producing) Acinetobacter radioresistens was isolated from a dog with cystitis and a cat with conjunctivitis. The MBL-producing A. radioresistens isolates were resistant to all of the β-lactam antibiotics used in the sensitivity tests, but were susceptible to gentamicin, amikacin, and minocycline. Also, one of the two strains of A. radioresistens was susceptible to ciprofloxacin and levofloxacin. These two cases were cured by administration of tetracyclines and fluoroquinolones, which elicited a positive result in the sensitivity tests...

Both complement activation and certain infections (including those with Yersinia sp.) may contribute to the pathogenesis of juvenile idiopathic arthritis (JIA). We investigated factors specific for the lectin pathway of complement: mannose-binding lectin (MBL), ficolins and associated serine protease-2 (MASP-2), in 144 patients and 98 controls. 106 patients had oligoarticular disease and 38 had polyarticular disease. In 51 patients (out of 133 tested), Yersinia-reactive antibodies were found (JIA Ye+ group)...

In Denmark, patients with serious nonspecific symptoms and signs of cancer (NSSC) are referred to the diagnostic outpatient clinics (DOCs) where an accelerated cancer diagnostic program is initiated. Various immunological and inflammatory biomarkers have been associated with cancer, including soluble urokinase plasminogen activator receptor (suPAR) and the pattern recognition receptors (PRRs) pentraxin-3, mannose-binding lectin, ficolin-1, ficolin-2 and ficolin-3. We aimed to evaluate these biomarkers and compare their diagnostic ability to classical biomarkers for diagnosing cancer in patients with NSSC...

In this study, the prevalence and characteristics of metallo-β-lactamase (MBL)-producing Pseudomonas aeruginosa isolates in South Korea were investigated. Among 215 P. aeruginosa isolates collected from eight hospitals, 77 (35.8%) and 72 (33.5%) were resistant to imipenem and meropenem, respectively. Of the 77 imipenem-resistant isolates, MBL genes were identified in 34 isolates (blaIMP-6 in 33 isolates and blaVIM-2 in 1 isolate). All of the MBL-producing isolates belonged to a globally prevailing genotype, sequence type 235 (ST235), and all of the IMP-6-producing isolates showed a deletion of nucleotide 209 of the porin gene oprD...

The two primary categories for eigenstate phases of matter at a finite temperature are many-body localization (MBL) and the eigenstate thermalization hypothesis (ETH). We show that, in the paradigmatic quantum p-spin models of the spin-glass theory, eigenstates violate the ETH yet are not MBL either. A mobility edge, which we locate using the forward-scattering approximation and replica techniques, separates the nonergodic phase at a small transverse field from an ergodic phase at a large transverse field. The nonergodic phase is also bounded from above in temperature, by a transition in configuration-space statistics reminiscent of the clustering transition in the spin-glass theory...

We introduce an analytic approach to many-body localization (MBL) in random spin chains. We consider MBL within a first quantized framework where it becomes a localization phenomenon in the high-dimensional lattice defined by the Hilbert space of the clean system. Designed in analogy with the field-theory description of single particle localization, our approach describes wave package propagation on that lattice after a disorder average has been performed and the system is controlled by only a few universal parameters...

Patients diagnosed with chronic lymphocytic leukemia display a high incidence of infections due to an associated immunodeficiency that includes hypogammaglobulinemia. A higher risk of infections has also been recently reported for high-count monoclonal B-cell lymphocytosis, while no information is available in low-count monoclonal B-cell lymphocytosis. Here, we evaluated the status of the humoral immune system in patients with chronic lymphocytic leukemia (n=58), as well as in low- (n=71) and high-count (n=29) monoclonal B-cell lymphocytosis vs...

In this work, we use exact matrix diagonalization to explore the many-body localization (MBL) transitions in quantum Ising chains with disordered nearest-neighbour couplings, disordered next-nearest-neighbour couplings and disordered external fields. It is demonstrated that the fidelity can be used to characterize the interaction-driven MBL transition in this closed spin system in a manner that is consistent with previous analytical and numerical results. We compute the fidelity for high-energy many-body eigenstates, namely, the excited-state fidelity...

BACKGROUND: Aggressive periodontitis renders a great challenge to the conventional implant due to the risks of infection and ongoing marginal bone loss (MBL). A study about full-arch immediate implant and restoration in patients with advanced generalized aggressive periodontitis (GAP) was not read, even though the All-on-4 concept has been proven to be predictable for edentulous patients. PURPOSE: This prospective study aimed to evaluate the feasibility and medium-term outcomes of immediate implant and rehabilitation based on the All-on-4 concept in patients with advanced GAP via clinical and radiographic analyses...
