Empowering a qudit-based quantum processor by traversing the dual bosonic ladder.

High-dimensional quantum information processing has emerged as a promising avenue to transcend hardware limitations and advance the frontiers of quantum technologies. Harnessing the untapped potential of the so-called qudits necessitates the development of quantum protocols beyond the established qubit methodologies. Here, we present a robust, hardware-efficient, and scalable approach for operating multidimensional solid-state systems using Raman-assisted two-photon interactions.

High-fidelity qutrit entangling gates for superconducting circuits.

Ternary quantum information processing in superconducting devices poses a promising alternative to its more popular binary counterpart through larger, more connected computational spaces and proposed advantages in quantum simulation and error correction. Although generally operated as qubits, transmons have readily addressable higher levels, making them natural candidates for operation as quantum three-level systems (qutrits). Recent works in transmon devices have realized high fidelity single qutrit operation.

A longitudinal study of naloxone opioid overdose awareness and reversal training for first-year medical students: specific elements require reinforcement.

Background: The opioid epidemic is a progressively worsening public health crisis that continues to impact healthcare system strategies such as overdose reversal and destigmatization. Even among healthcare professionals, there remains a lack of confidence in naloxone administration and a prevalence of stigma. While training can play a major impact in reducing these shortcomings, the long-term effectiveness has yet to be characterized in training healthcare professionals.

Reducing the stigma surrounding opioid use disorder: evaluating an opioid overdose prevention training program applied to a diverse population.

Background: The opioid epidemic is a rapidly growing public health concern in the USA, as the number of overdose deaths continues to increase each year. One strategy for combating the rising number of overdoses is through opioid overdose prevention programs (OOPPs).

Objective: To evaluate the effectiveness of an innovative OOPP, with changes in knowledge and attitudes serving as the primary outcome measures.

Experiences and Outcomes of Attending a Facial Pain Management Program: A Qualitative Study.

Aims: To understand the experiences of patients diagnosed with chronic facial pain (CFP) who attended a specialist facial pain management program (PMP); specifically, to explore how they experienced attending the facial PMP itself and how they felt it impacted their management of CFP.

Methods: Qualitative methodology and focus groups were used to gather patients' views and experiences of attending a facial PMP. Two focus groups were conducted for patients who had all completed the facial PMP.

A Comparative Analysis of Online Versus in-Person Opioid Overdose Awareness and Reversal Training for First-Year Medical Students.

Physicians trained in opioid use disorder (OUD) harm reduction can mitigate opioid overdose deaths by prescribing naloxone and educating patients about its use. Unfortunately, many physicians possess OUD stigma. Training during medical school presents an opportunity to reduce OUD stigma and improve opioid overdose reversal knowledge.

Measurements of the absorption cross section of (13)CHO(13)CHO at visible wavelengths and application to DOAS retrievals.

The trace gas glyoxal (CHOCHO) forms from the atmospheric oxidation of hydrocarbons and is a precursor to secondary organic aerosol. We have measured the absorption cross section of disubstituted (13)CHO(13)CHO ((13)C glyoxal) at moderately high (1 cm(-1)) optical resolution between 21 280 and 23 260 cm(-1) (430-470 nm). The isotopic shifts in the position of absorption features were found to be largest near 455 nm (Δν = 14 cm(-1); Δλ = 0.

Low-grade fibromyxoid sarcoma of the vulva.

Patients with a low-grade fibromyxoid sarcoma of the vulva should undergo wide local excision as the primary treatment, but only after the histologic diagnosis is confirmed.

Inactivation and clearance of viruses during the manufacture of high purity factor IX.

Haemophilia is a bleeding disorder characterised by a deficiency in Factor IX. Replacement therapy in the form of a Factor IX concentrate is a widely accepted practice. In this paper we describe a double virus inactivated chromatographic process for producing a high purity Factor IX product, MonoFIX((R))-VF.

Chromatographic removal and heat inactivation of hepatitis B virus during the manufacture of human albumin.

The purpose of the present study was to examine the efficacy of the chromatographic and pasteurization steps, employed in the manufacture of human albumin, in the removal and/or inactivation of hepatitis B virus (HBV). Most human albumins manufactured today are prepared from donor plasma by fractionation methods that use precipitation with cold ethanol. CSL Limited, an Australian biopharmaceutical company, has recently converted its method of manufacture for albumin from a traditional Cohn fractionation method to a method employing chromatographic techniques.

Chromatographic removal and heat inactivation of hepatitis A virus during manufacture of human albumin.

CSL Limited, an Australian biopharmaceutical company, has recently converted its method of manufacture for human albumin from a traditional Cohn-ethanol fractionation method to a method employing chromatographic techniques. Studies were undertaken to determine the efficiency of the chromatographic and pasteurization steps used in the manufacture of Albumex(R) (CSL's trade name for albumin) in removing and inactivating the potential viral contaminant, hepatitis A virus (HAV). The manufacturing process for Albumex(R) includes three chromatographic steps, two of which are ion-exchange steps (DEAE-Sepharose(R) Fast Flow and CM-Sepharose(R) Fast Flow) and the third is a gel-filtration step (Sephacryl(R) S200 HR).

Selection of an adjuvant for vaccination with the malaria antigen, MSA-2.

Various formulations of the Plasmodium falciparum merozoite surface antigen, MSA-2, were made and tested in animals in order to select one for use in human vaccine trials. Recombinant constructs representing both major allelic forms of MSA-2 were formulated with a range of adjuvants and used to immunize rabbits, mice and sheep. After immunization, antibody responses obtained with the most potent adjuvants were at least tenfold greater than responses obtained with the least potent adjuvant Alhydrogel, which was used as the reference standard, although its lower potency indicated against its further use in clinical trials.

Limited proteolysis study of structure-function relationships in Sh I, a polypeptide neurotoxin from a sea anemone.

The structure-function relationships of the neurotoxic polypeptide Sh I, from the sea anemone Stichodactyla helianthus, have been studied using limited proteolysis with trypsin and endoproteinase Lys-C. Major products from each of the proteolytic digests were characterised using N-terminal peptide sequencing and amino-acid analysis or mass spectrometry. Of the six possible tryptic cleavage sites in Sh I, the bonds adjacent to Arg-13 and Lys-47 were found to be the most susceptible, complete cleavage occurring within minutes.

A unique interhelical insertion in plasminogen activator inhibitor-2 contains three glutamines, Gln83, Gln84, Gln86, essential for transglutaminase-mediated cross-linking.

Plasminogen activator inhibitor type 2 (PAI-2) prevents fibrinolysis by blocking plasminogen activators. It is expressed principally by trophoblast cells and macrophages. PAI-2 in trophoblast membranes has been found cross-linked to large complexes apparently catalyzed by trophoblast transglutaminase (Jensen, P.

The isolation of activin from ovine amniotic fluid.

During a study of the levels of inhibin and follistatin in ovine amniotic fluid, we noted that although detectable levels of immunoactive inhibin and follistatin were found throughout gestation, the addition of amniotic fluid to a rat anterior pituitary cell culture resulted in a stimulation, rather than the expected suppression, of FSH concentrations. These data suggested the possibility that activin was present in amniotic fluid. We, therefore, set out to isolate the molecules responsible for this activin-like activity and determine their structure.

Linear and cyclic peptide analogues of the polypeptide cardiac stimulant, anthopleurin-A. 1H-NMR and biological activity studies.

A loop corresponding to residues 8-17 in the polypeptide cardiac stimulant anthopleurin-A is known to be important for the cardiostimulant activity of this molecule. To investigate the activity and possible conformations of this loop in isolation, two synthetic peptides have been studied. The first corresponds to residues 6-20 of anthopleurin-A with Cys6 replaced by Thr, and the second to residues 6-21 of anthopleurin-A, with Thr21 replaced by Cys.

Comparative study of the T cell response to two allelic forms of a malarial vaccine candidate protein.

T cell responses to two allelic forms of the merozoite surface Ag 2 (MSA2) of Plasmodium falciparum were mapped in mice using the rMSA2 proteins, Ag 1609 which has the sequence of the FCQ27/PNG strain and Ag 1615 which has the sequence of the Indochina 1 strain. Lymph node cells of BL/10 and B10.BR mice immunized with either Ag 1609 or Ag 1615 responded to both Ag in in vitro proliferation assays.

Immunization of owl monkeys with the ring-infected erythrocyte surface antigen of Plasmodium falciparum.

Aotus nancymai were immunized with the 4-mer, 8-mer, and 11-mer repeat peptides of the ring-infected erythrocyte surface antigen molecule of Plasmodium falciparum conjugated to diphtheria toxoid with muramyl dipeptide (MDP) as adjuvant. Immunization failed to induce protective immunity against the Uganda Palo Alto strain of P. falciparum as judged by maximum levels of parasitemia of immunized monkeys relative to those of controls.

Physicochemical and biological characterization of recombinant human inhibin A.

Recombinant human inhibin A was isolated from recombinant mammalian cell line culture media. Two forms of inhibin were identified with Mr of 34 and 31 Kd composed of subunits (alpha, beta) of 24 and 15 Kd and 21 and 15 Kd respectively. Both forms are bioactive in an inhibin in vitro bioassay and immunoactive with potencies comparable to or higher than purified bovine inhibin.

Plasminogen activator inhibitor 2 (PAI-2) is not inactivated by exposure to oxidants which can be released from activated neutrophils.

Purified recombinant human monocyte plasminogen activator inhibitor 2 (PAI-2) retained inhibitory activity after exposure to a number of oxidants, including hypochlorite anion (OCl-), chloramine-T (CT) and hydrogen peroxide (H2O2). Analysis of PAI-2 exposed to oxidants by gel filtration chromatography and SDS-PAGE indicated that although the protein could no longer be detected by silver staining, this was not due to fragmentation of the PAI-2 molecule. The sensitivity of a number of serine protease inhibitors (serpins), (eg.

Isolation of inhibin alpha-subunit precursor proteins from bovine follicular fluid.

Two proteins with structural characteristics similar to peptide sequences identified in the inhibin alpha-subunit precursor sequence have been isolated from bovine follicular fluid. A side-fraction from the purification of bovine follicular fluid inhibin with high levels of inhibin immunoactivity relative to its inhibin bioactivity was fractionated through a sequence of procedures which included triazine dye affinity and phenyl-Sepharose chromatography, gel permeation chromatography on Sephadex G-100, reverse phase HPLC, and preparative polyacrylamide gel electrophoresis. The first of the two proteins identified had a molecular mass of 25-26K under reducing and nonreducing conditions and a NH2-terminal sequence identical to that of 43K inhibin alpha-subunit and showed minimal activity (less than 2% activity) compared with bovine 31K inhibin in either the inhibin in vitro bioassay or the RIA.
