Abstract:

ABSTRACT We used a murine model of catheter-associated biofilm formation to determine whether the mutation of the staphylococcal accessory regulator (sarA) has an impact on the susceptibility of established Staphylococcus aureus biofilms to treatment with daptomycin in vivo. The experiments were done with two clinical isolates, one of which (UAMS-1) was obtained from the bone of a patient suffering from osteomyelitis, while the other (UAMS-1625) is an isolate of the USA300 clonal lineage of community-acquired methicillin (meticillin)-resistant S. aureus.

Abstract:

ABSTRACT Much of the research aimed at defining the pathogenesis of Staphylococcus aureus has been done with a limited number of strains, most notably the 8325-4 derivative RN6390. Several lines of evidence indicate that this strain is unique by comparison to clinical isolates of S. aureus. Based on this, we have focused our efforts on two clinical isolates (UAMS-1 and UAMS-601), both of which are hypervirulent in our animal models of musculoskeletal infection. In this study, we used comparative genomic hybridization to assess the genome content of these two isolates relative to RN6390 and eac

Abstract. This article addresses unaccompanied minor asylum seekers' (UAMs) educational experiences in Switzerland. Drawing on ethnographic research we explore what it means for UAMs to get an education and how having access or not having access to particular forms and spaces of education plays a part in the process of their subject formations. We get insights into such processes in diverse spaces of education and in phases of transition between them. We point out how educational arrangements can produce feelings of belonging and non-belonging and highlight that these feelings are entangled wi

This article explores unaccompanied adolescent minors’ (UAMs) experiences of deterrent practices at internal EU borders while being on the move. Previous studies have acknowledged the securitisation of external borders through gatekeeping and fencing practices; however, there is a recent and continued renationalisation of internal EU borders by the member states. Like other migrants who are travelling irregularly, UAMs also often face harsh living conditions and repeated rights violations in border areas, regardless of their specific rights to protection and psychological needs.

Abstract Focusing on practices and representations mobilized by street-level workers in the management of North African unaccompanied minor migrants (UAMs) in Geneva, I take a closer look at the everyday assessment and production of UAMs’ deservingness in the context of humanitarianism.

I further demonstrate how the social construction of childhood, race, and gender influence street-level workers’ perceptions.

Abstract Despite the increasing social impact of unaccompanied migrant minors (UAMs) in many European Union (EU) member states, EU regulations on UAMs are still inadequate and the necessary protection measures are thus insufficient. More specifically, the “best interest of the child”, stated in a large number of international documents, may not be properly guaranteed. In addition, there is often a discrepancy between the rights of migrant children, according to the international legislation, and the actual protection they receive.

Abstract:

The production of Staphylococcus aureus virulence factors is under the control of complex regulatory circuits. Most studies aimed at defining these regulatory networks have focused on derivatives of the strain NCTC 8325, most notably RN6390. However, all NCTC 8325 derivatives, including RN6390, possess an 11 bp deletion in rsbU. This deletion renders NCTC 8325 derivatives naturally sigma-factor-B deficient. Recent studies have shown that RN6390 is also deficient, in comparison to clinical isolates, with respect to biofilm formation, a process which is important for both pathogenesis and antimi

ABSTRACT We previously demonstrated that mutation of the staphylococcal accessory regulator (sarA) in a clinical isolate of Staphylococcus aureus (UAMS-1) results in an impaired capacity to form a biofilm in vitro (K. E. Beenken, J. S. Blevins, and M. S. Smeltzer, Infect. Immun. 71:4206-4211, 2003). In this report, we used a murine model of catheter-based biofilm formation to demonstrate that a UAMS-1 sarA mutant also has a reduced capacity to form a biofilm in vivo. Surprisingly, mutation of the UAMS-1 ica locus had little impact on biofilm formation in vitro or in vivo. In an effort to ident

Abstract:

ABSTRACT Mutation of sarA resulted in a reduced capacity to form a biofilm in six of the eight Staphylococcus aureus strains we tested (UAMS-1, UAMS-601, SA113, SC-01, S6C, and DB). The exceptions were Newman, which formed a poor biofilm under all conditions, and RN6390, which consistently formed a biofilm only after mutation of agr. Mutation of agr in other strains had little impact on biofilm formation. In every strain other than Newman, including RN6390, simultaneous mutation of sarA and agr resulted in a phenotype like that observed with the sarA mutants. Complementation studies using a sa

Abstract:

Background: Treating an underactive bladder (UAB) is challenging. Previously, we introduced a more precise method of transvaginal ultrasound-guided botulinum toxin A (BoNT-A) injection into the external urethral sphincter as a treatment option for patients with UABs. Although many patients experience good results, those with an UAB and excessive residual urine still require catheterization. Therefore, we developed a new method that combines transvaginal ultrasound-guided BoNT-A injection with a transurethral bladder neck incision. Methods: A prospective study was conducted on 16 patients who e

Abstract:

The anaerobic ammonium oxidation (Anammox) process is a new efficient and cost effective method of ammonium removal from wastewater. Under strictly anoxic condition, ammonium is directly oxidised with nitrite as electron acceptor to dinitrogen gas. However, it is extremely difficult to cultivate Anammox bacteria due to their low growth rate. This suggests that a rapid and efficient start-up of Anammox process is the key to practical applications. To screen appropriate seeding sludge with high Anammox potential, a real-time quantitative PCR assay with newly designed primers has been developed.

BRAF V600E is the most common mutation in conventional ameloblastoma (AM) of the mandible. In contrast, maxillary AMs appear to harbor more frequently RAS, FGFR2, or SMO mutations. Unicystic ameloblastoma (UAM) is considered a less aggressive variant of ameloblastoma, amenable to more conservative treatment, and classified as a distinct entity. The aim of this study was to characterize the mutation profile of UAM ( n = 39) and to compare it to conventional AM ( n = 39). The associations between mutation status and recurrence probability were also analyzed. In the mandible, 94% of UAMs (29/31,

Abstract:

ABSTRACT The accessory gene regulator (agr) and the staphylococcal accessory regulator (sar) are central regulatory elements that control the production of Staphylococcus aureus virulence factors. To date, the functions of these loci have been defined almost exclusively using RN6390, which is representative of the laboratory strain 8325-4. However, RN6390 was recently shown to have a mutation in rsbU that results in a phenotype resembling that of a sigB mutant (I. Kullik et al., J. Bacteriol. 180:4814–4820, 1998).

Uterine arteriovenous malformations (UAVMs) that occur after birth are a rare cause of late postpartum hemorrhage. Acquired UAVMs usually occur in conjunction with pathology of the placenta. In the spectrum of placenta accreta (PAS), subinvolution of the placental bed plays an important role in its pathophysiology. We present a case of UAVM in a pregnant woman with PAS who presented with marked metrorrhagia after delivery, which was treated with classical management. Then, 35 days later, she presented to the emergency room with severe metrorrhagia. As it was suspected that she had placental re

Simulating the acoustic field excited by pulse sound sources holds significant practical value in computational ocean acoustics.

TD-UAPMs solve the wave equation in the time domain without requiring frequency decomposition, providing a more intuitive explanation of the physical process of sound energy propagation over time.

A novel adaptive law is employed to enable aerial manipulators to manage the inertia parameter changes that occur when the manipulator moves or picks up unknown objects during any phase of the UAM’s flight maneuver. The adaptive law utilizes a Kalman filter to estimate a set of weighting factors employed to adjust the control gain matrix of a previously developed INDI control law formulated for the corresponding UAV (no manipulator included).
