Use of infection control measures in people with chronic lung disease: mixed methods study.

Background: The introduction of community infection control measures during the COVID-19 pandemic was associated with a reduction in acute exacerbations of lung disease. We aimed to understand the acceptability of continued use of infection control measures among people with chronic lung disease and to understand the barriers and facilitators of use.

Methods: Australian adults with chronic lung disease were invited to an online survey (last quarter of 2021) to specify infection control measures they would continue themselves post-pandemic and those they perceived should be adopted by the community.

The immunohistochemical, DNA methylation, and chromosomal copy number profile of cauda equina paraganglioma is distinct from extra-spinal paraganglioma.

Paragangliomas are neuroendocrine tumors of the autonomic nervous system that are variably clinically functional and have a potential for metastasis. Up to 40% occur in the setting of a hereditary syndrome, most commonly due to germline mutations in succinate dehydrogenase (SDHx) genes. Immunohistochemically, paragangliomas are characteristically GATA3-positive and cytokeratin-negative, with loss of SDHB expression in most hereditary cases.

Obstructive sleep apnea is associated with severity and long-term prognosis of acute coronary syndrome.

Background: Obstructive sleep apnea (OSA) is a common disease in patients with acute coronary syndrome (ACS) and associated with an increased risk of fatal and nonfatal cardiovascular events. However, most patients in previous study were treated with bare metal stents and the sample sizes were relatively low. The goal of this study was to evaluate the influence of OSA on the severity and prognosis of patients admitted for ACS.

Immunophenotypic and genotypic markers of follicular center cell neoplasia in diffuse large B-cell lymphomas.

Diffuse large B-cell lymphomas (DLBCL) are a biologically and clinically heterogeneous entity. Although some DLBCL represent transformation of follicular lymphomas (FL), the proportion that is of follicular center cell (FCC) origin remains uncertain. Immunophenotypic and genotypic markers used to suggest a FCC origin for a lymphoma (bcl-6 and CD10 expression, lack of CD138 expression, bcl-2 rearrangements [R]) or to subdivide DLBCL (bcl-2 expression, bcl-6 R) were therefore investigated in 22 FL and 44 DLBCL using paraffin section immunostains and Southern blot/polymerase chain reaction analysis.

A healthcare staff decision model considering the effects of staff cross-training.

In this study a staff planning model for a health service clinic has been developed and validated using an example case of a health service clinic. The primary purpose of this research is to develop a representative staff planning model which balances the cost and benefits of staff task flexibility through cross-training for a healthcare facility. Additionally, legal requirements for task substitution in the healthcare industry have been considered in the model.

Pain sensitivity and individual differences in self-reported sexual behavior.

The relationship between sexual behavior and pain sensitivity was assessed in 27 heterosexual men and 20 heterosexual women. Sexual behavior measures included sexual motivation and ratings of subjective sexual arousal to and enjoyment of an auditory stimulus. Pain sensitivity measures were pain threshold and pain tolerance in a cold pressor task.

The Sexual Desire Inventory as a measure of sexual motivation in college students.

The human sexual response consists of at least two phases of behavior, the motivational phase and the consummatory phase, which are difficult to isolate. Sexual motivation questionnaires commonly contain items that assume sexual intercourse or partners' experience and are often difficult to use with sexually inexperienced persons. The Sexual Desire Inventory by Spector, Carey, and Steinberg does not appear to be confounded with consummatory behavior.

Experimental entanglement of four particles.

Quantum mechanics allows for many-particle wavefunctions that cannot be factorized into a product of single-particle wavefunctions, even when the constituent particles are entirely distinct. Such 'entangled' states explicitly demonstrate the non-local character of quantum theory, having potential applications in high-precision spectroscopy, quantum communication, cryptography and computation. In general, the more particles that can be entangled, the more clearly nonclassical effects are exhibited--and the more useful the states are for quantum applications.

Decoherence of quantum superpositions through coupling to engineered reservoirs.

The theory of quantum mechanics applies to closed systems. In such ideal situations, a single atom can, for example, exist simultaneously in a superposition of two different spatial locations. In contrast, real systems always interact with their environment, with the consequence that macroscopic quantum superpositions (as illustrated by the 'Schrodinger's cat' thought-experiment) are not observed.

Affective properties of intra-medial preoptic area injections of testosterone in male rats.

On alternating days, adult male Long-Evans rats implanted with unilateral cannulae in the medial preoptic area (MPOA) received intracerebral injections of testosterone (0.05, 0.1 or 0.

Experimental Issues in Coherent Quantum-State Manipulation of Trapped Atomic Ions.

Methods for, and limitations to, the generation of entangled states of trapped atomic ions are examined. As much as possible, state manipulations are described in terms of quantum logic operations since the conditional dynamics implicit in quantum logic is central to the creation of entanglement. Keeping with current interest, some experimental issues in the proposal for trappedion quantum computation by J.

A "Schrodinger Cat" Superposition State of an Atom.

A "Schrodinger cat"-like state of matter was generated at the single atom level. A trapped 9Be+ ion was laser-cooled to the zero-point energy and then prepared in a superposition of spatially separated coherent harmonic oscillator states. This state was created by application of a sequence of laser pulses, which entangles internal (electronic) and external (motional) states of the ion.

Characteristics of ecto-ATPase of Xenopus oocytes and the inhibitory actions of suramin on ATP breakdown.

Ecto-ATPase activity of Xenopus oocytes was studied by measuring the production of inorganic phosphate (Pi) from the breakdown of extracellular ATP. Enzyme activity involved Ca2+/Mg(2+)-dependent and Ca2+/Mg(2+)-independent dephosphorylation of ATP. Ca2+/Mg(2+)-dependent ecto-ATPase was active over a limited range of 0.

Staining for Bcl-2 protein helps to distinguish benign from malignant lymphoid aggregates in bone marrow biopsies.

Lymphoid nodules in a bone marrow biopsy may be either benign or malignant. Morphological clues may help to differentiate the benign from the malignant nodules. However, it is sometimes difficult, if not impossible, to make this distinction, especially in patients with a known low-grade lymphocytic malignancy.
