Objective: Identification of those at high and low risk of disease relapse is a major unmet need in the management of patients with ANCA-associated vasculitis (AAV). Precise stratification would allow tailoring of immunosuppressive medication. We profiled the autoantibody repertoire of AAV patients in remission to identify novel autoantibodies associated with relapse risk.

In this paper, we theoretically investigate the magnomechanically induced transparency (MIT) phenomenon and slow-fast light propagation in a microwave cavity-magnomechanical system which includes a levitated ferromagnetic sphere. Magnetic dipole interaction determines the interaction between the photon, magnon, and center of mass motion of the cavity-magnomechanical system. As a result, we find that apart from coupling strength, which has an important role in MIT, the levitated ferromagnetic sphere's position provides us a parameter to manipulate the width of the transparency window.

ANCA-associated vasculitides (AAV) are rare autoimmune diseases causing inflammation and damage to small blood vessels. New autoantibody biomarkers are needed to improve the diagnosis and treatment of AAV patients. In this study, we aimed to profile the autoantibody repertoire of AAV patients using in-house developed antigen arrays to identify previously unreported antibodies linked to the disease per se, clinical subgroups, or clinical activity.

Systemic sclerosis (SSc) is a rare autoimmune systemic disease that leads to decreased survival and quality of life due to fibrosis, inflammation, and vascular damage in the skin and/or vital organs. Early diagnosis is crucial for clinical benefit in SSc patients. Our study aimed to identify autoantibodies in the plasma of SSc patients that are associated with fibrosis in SSc.

This study aimed to develop a new bioactive wound dressing based on electrospun poly (L-lactide-co-D, L-lactide) (PLDLLA) nanofibers containing Lawsonia inermis (LI) for burn wounds. The SEM results showed that loading LI increased the average diameter of PLDLLA nanofibers to 528 nm with smooth and beadless morphology. The analysis of LI release from PLDLLA nanofibers and film samples was measured by UV-vis spectrophotometry, and the obtained results revealed that LI molecules could diffuse from the nanofibrous sample with higher rate than film during 48 h.

Introduction We evaluate diagnostic radiology residents' perceptions of an ultrasound-guided and stereotactic breast biopsy simulator used at an academic medical center. This simulator is low-cost and easily reproducible. We aim to understand if this simulator improves residents' self-reported confidence in performing breast biopsy procedures on live patients.

Article Synopsis
  • * Researchers analyzed over 100 SARS-CoV-2 protein representations and selected three key antigens from the spike glycoprotein and nucleocapsid protein for further testing on samples from COVID-19 patients and uninfected controls.
  • * The final assay achieved impressive accuracy, with sensitivities ranging from 99.1% to 99.7% and specificities from 95.7% to 100%, especially when using two antigens together, demonstrating the assay's potential for reliable COVID-19 detection.

Background: Declining humoral immunity in coronavirus disease 2019 (COVID-19) patients and possible reinfection have raised concern. Mucosal immunity, particularly salivary antibodies, may be short lived although long-term studies are lacking.

Methods: Using a multiplex bead-based array platform, we investigated antibodies specific to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) proteins in 256 saliva samples from convalescent patients 1-9 months after symptomatic COVID-19 (n = 74, cohort 1), undiagnosed individuals with self-reported questionnaires (n = 147, cohort 2), and individuals sampled prepandemic (n = 35, cohort 3).

Objective: To improve urotrauma care by describing veterans' current demographics and needs assessment during transitional care to the Veteran Health Administration (VHA) system.

Methods: We utilized our previously identified cohorts obtained from the DoD Trauma Registry data for male service members injured in theater linked with VHA electronic health records. We included veterans who received care at VHA at least once from October 2001 through September 2011 for chart review.

SARS-CoV-2 may pose an occupational health risk to healthcare workers. Here, we report the seroprevalence of SARS-CoV-2 antibodies, self-reported symptoms and occupational exposure to SARS-CoV-2 among healthcare workers at a large acute care hospital in Sweden. The seroprevalence of IgG antibodies against SARS-CoV-2 was 19.

While a batch of efforts are fastened on synthesizing the novel targeted anti-cancer agents, recent investigations have achieved a breakthrough in identifying a favorable anti-tumor activity for some supportive drugs, which their safety have been confirmed thus far. The results of the present study highlighted the efficacy of Aprepitant, an oral antagonist of the neurokinin-1 receptor (NK1R), against both APL (NB4) and pre-B ALL (Nalm-6) cell lines; however, a differential sensitivity pattern was found in these cells. To the best of our knowledge, this is the first time that the molecular mechanisms of resistance to Aprepitant have been investigated and, herein, we proposed that the effectiveness of Aprepitant could be overshadowed, at least partially, through over-activated nuclear factor-κB in Nalm-6 pre-B ALL cells.

Genetic and laboratory studies have remodeled the conventional understanding of cancer pathogenesis by identifying different molecular alterations. Intrigued by the contribution of neurokinin-1 receptor (NK1R) network in cancer pathogenesis, we investigated the antileukemic effects of aprepitant, a nonpeptide antagonist of NK1R, in a panel of hematological cell lines. In this study, we found that aprepitant decreased the survival of all the tested cells; however, as compared with NB4, viability of the other cell lines was inhibited at higher concentrations.

The thermal responsive behavior of adsorbed layers of diblock copolymers of poly(-isopropylacrylamide) (PNIPAAM) and poly((3-acrylamidopropyl)trimethylammonium chloride) (PAMPTMA(+)) with γ-cyclodextrin (γ-CD) at the solid/liquid interface has been investigated using three in situ techniques: null ellipsometry, quartz-crystal microbalance with dissipation monitoring, and neutron reflectometry. The measurements provided information about the adsorbed amounts, the layer thickness, hydration and viscoelastic properties, and the interfacial structure and composition. The copolymers adsorb to silica with the cationic PAMPTMA(+) blocks sitting as anchors in a flat conformation and the PNIPAAM chains extending into the solution.

Increasing number of genetic and cancer biology studies indicated a prominent role for tachykinin NK receptor (NKR) in cancer cell growth and survival. Considering the fact that neoplastic lymphoid precursors in acute lymphoblastic leukemia (ALL) carry a three- to four-fold NKR expression as compared to normal lymphocytes, using NKR antagonist seems to be noteworthy in the treatment of ALL patients. In this study, we found that inhibition of NKR with aprepitant, a selective high-affinity antagonist of the human NKR, exerts cytotoxic and anti-proliferative effects against pre-B ALL-derived Nalm-6 cells either as single drug or in combination with doxorubicin.

Arsenic trioxide (ATO), a traditional Chinese medicine, has long been of biomedical interest and is largely used for treatment of a broad spectrum of cancers. Melatonin, a naturally occurring indoleamine synthesized in the pineal gland, has been considered as a biomarker for endocrine-dependent tumors, particularly breast cancer. An increasing number of studies indicate that melatonin could be an attractive candidate for combined therapy due to its anti-oxidant and cytotoxic activities.
