The prevalence of abdominal aortic aneurysm (AAA) is reported to be 2.2%-8% among men >65 years. During recent years, screening programs have been developed to detect AAA, prevent ruptures, and thereby saving lives. Therefore, most men with the diagnosis are monitored conservatively with regular reviews. The objective of the study was to describe how men diagnosed with abdominal aortic aneurysm <55 mm discovered by screening experience the process and diagnosis from invitation to 1 year after screening...

INTRODUCTION: The rationale of focal articular prosthetic resurfacing used as a primary arthroplasty procedure in the treatment of articular cartilage defects is still under debate. Conflicting reports raise concern about high rates of re-operations and continued development of osteoarthritis, while others have reported good outcomes. The goal of this paper is to present the long-term results of two patients with a 12-year follow-up and to report the results of a literature review. MATERIALS AND METHODS: Two patients (male, 70 years; female 63 years) with a follow-up of 12 years were reviewed...

Despite the availability of vaccines, Streptococcus pneumoniae remains a leading cause of life-threatening infections, such as pneumonia, bacteremia and meningitis. Polymorphonuclear leukocytes (PMNs) are a key determinant of disease course, because optimal host defense requires an initial robust pulmonary PMN response to control bacterial numbers followed by modulation of this response later in infection. The elderly, who manifest a general decline in immune function and higher basal levels of inflammation, are at increased risk of developing pneumococcal pneumonia...

Virus-like vesicles (VLVs) are membrane enclosed vesicles that resemble native enveloped viruses in organization, but lack viral capsid and genome. During the productive infection of tumor associated gamma-herpesviruses, both virions and VLVs are produced and released into the extracellular space. However, studies of gamma-herpesvirus associated VLVs have been largely restricted by the technical difficulty of separating VLVs from mature virions. Here, we report a strategy of using a Kaposi's sarcoma-associated herpesvirus (KSHV) mutant defective in small capsid protein, unable to produce mature virions, to selectively isolate VLVs...

Rationale: Increasing evidence indicates that alterations of the cerebral microcirculation may play a role in Alzheimer's disease (AD), the leading cause of late-life dementia. The amyloid-β peptide (Aβ), a key pathogenic factor in AD, induces profound alterations in neurovascular regulation through the innate immunity receptor CD36, which, in turn, activates a Nox2-containing NADPH oxidase leading to cerebrovascular oxidative stress. Brain perivascular macrophages (PVM) located in the perivascular space, a major site of brain Aβ collection and clearance, are juxtaposed to the wall of intracerebral resistance vessels and are a powerful source of reactive oxygen species (ROS)...

The study of zebrafish behavior represents a cornerstone upon which basic researchers promise to advance knowledge in life sciences. Although zebrafish swim in a three-dimensional (3D) space, their behavior in the lab is almost exclusively scored in two dimensions, whereby zebrafish are recorded using a single camera providing 2D videos. Whether this dimensional reduction preserves the reliability of data has not been addressed. Here we show that, compared to a 3D observation, 2D data are flawed by over-reporting and under-reporting of locomotory differences...

Retropharyngeal abscess is an infection involving the retropharyngeal space which is posterior to the pharynx and oesophagus, and it results as a complication of a primary infection elsewhere in the head and neck including the nasopharynx, paranasal sinuses, or middle ear, which drain lymph to the retropharyngeal lymph nodes. Their lymph nodes are prominent in children and atrophy with age. Therefore, retropharyngeal abscess is most frequently encountered in children, with 75% of cases occurring before the age of 5 years, and often in the first year of life...

Organisms in the wild have cryptic life stages that are sensitive to changing environmental conditions and can be difficult to survey. In this study, I used mark-recapture methods to repeatedly survey Anaea aidea (Nymphalidae) caterpillars in nature, then modeled caterpillar demography as a hidden Markov process to assess if temporal variability in temperature and density influence the survival and growth of A. aidea over time. Individual encounter histories result from the joint likelihood of being alive and observed in a particular stage, and I have included hidden states by separating demography and observations into parallel and independent processes...

Microbe-mineral interactions have become of interest for space exploration as microorganisms could be used to biomine from extra-terrestrial material and extract elements useful as micronutrients in life support systems. This research aimed to identify the impact of space flight on the long-term survival of Cupriavidus metallidurans CH34 in mineral water and the interaction with basalt, a lunar-type rock in preparation for the ESA spaceflight experiment, BIOROCK. Therefore, C. metallidurans CH34 cells were suspended in mineral water supplemented with or without crushed basalt and send for 3 months on board the Russian FOTON-M4 capsule...

Sequencing in all areas of the tree of life has produced >300,000 cytochrome P450 (CYP) sequences that have been mined and collected. Nomenclature has been assigned to >41,000 CYP sequences and the majority of the remainder has been sorted by BLAST searches into clans, families and subfamilies in preparation for naming. The P450 sequence space is being systematically explored and filled in. Well-studied groups like vertebrates are covered in greater depth while new insights are being added into uncharted territories like horseshoe crab (Limulus polyphemus), tardigrades (Hypsibius dujardini), velvet worm (Euperipatoides_rowelli), and basal land plants like hornworts, liverworts and mosses...

Factors that drive parasite specificity and differences in infection dynamics among alternative host species are important for ecology and evolution of host-parasite interactions, but still often poorly known in natural systems. Here, we investigated spatiotemporal dynamics of infection, host susceptibility and parasite-induced changes in host phenotype in a rarely explored host-parasite system, the Australapatemon sp. trematode infecting two sympatric species of freshwater leeches, Erpobdella octoculata and Helobdella stagnalis...

BACKGROUND: The success of needle decompression for tension pneumothorax is variable, and there are no objective measures assessing effective decompression. Colorimetric capnography, which detects carbon dioxide present within the pleural space, may serve as a simple test to assess effective needle decompression. METHODS: Three swine underwent traumatically induced tension pneumothorax, (n=15 standard of care, n=15 with needle capnography). Standard of care needle thoracostomy (n=15) using an 8 cm angiocatheter was performed...

Burst stimulation, as described by DeRidder, is a novel waveform made up of closely spaced, high-frequency electrical impulses delivered in packets, which are followed by a quiescent period or interburst interval. Electrically generated burst waveforms were initially designed to treat neural pathology in the auditory cortex and were later applied to the spinal cord through spinal cord stimulation (SCS) devices to treat chronic pain states. When Burst stimulation is applied to the spinal cord, the impulses travel to the thalamus and then diverge, targeting both the somatosensory cortex and the limbic system where they treat both the sensory, affective and attentional components of neuropathic pain...

OBJECTIVE: This qualitative study aimed to capture the experience of living in the ambivalent space between life and death for adults with recurrent suicide attempts (RSA). It sought to expand upon an earlier study that explored the processes involved in transitioning away from RSA among adults, which revealed that occupying this ambivalent space is a crucial part of this process. DESIGN: Interpretive phenomenological analysis (IPA) was used. This methodology was designed to explore the lived experiences and meaning making and enabled interpretation of the multidimensional subjective experiences of RSA participants...

Stability concerns of organic solar cell devices have led to the development of alternative hole transporting layers such as NiO which lead to superior device life times over conventional Poly(3,4-ethylenedioxythiophene) Polystyrene sulfonate (PEDOT:PSS) buffered solar cells. From the printability of such devices, it is imperative to be able to print NiO layers in the organic solar cell devices with normal architecture which has so far remained unreported. In this manuscript, we report on the successful ink-jet printing of very thin NiO thin films with controlled thickness and morphology and their integration in organic solar cell devices...

Spatial navigation planning ability relies on both mental imagery and cognitive flexibility. Considering the importance of planning ability in everyday life, several neuropsychological tests are used in clinical practice for its assessment, although some of these are not aimed at assessing the strategies of navigational planning. The Porteus Maze Test (PMT) and the Key Search Task (KST) require to plan a strategy in a maze and in an imagined space, respectively. To the best of our knowledge, although these two tests share some features, the relationship between them has never been explored...
