Critical role of neutralizing antibody for SARS-CoV-2 reinfection and transmission.
Abstract Cases of laboratory-confirmed SARS-CoV-2 reinfection have been reported in a number of countries. Further, the level of natural immunity induced by SARS-CoV-2 infection is not fully clear, nor is it clear if a primary infection is protective against reinfection. To investigate the potential association between serum antibody titres and reinfection of SARS-CoV-2, ferrets with different levels of NAb titres after primary SARS-CoV-2 infection were subjected to reinfection with a heterologous SARS-CoV-2 strain. All heterologous SARS-CoV-2 reinfected ferrets showed active virus replication in the upper respira...

Direct notification of cervical cytology results to women improves follow-up in cervical cancer screening - A cluster-randomised trial.
Abstract Up to half of all women do not receive follow-up as recommended after cervical cytology testing and are thus at increased risk of dysplasia progression. Women from lower social positions are at increased risk of not receiving follow-up. Sample takers, often general practitioners, convey results to women, but communication problems constitute a challenge. We aimed to investigate the effect of direct notification of cervical cytology results on follow-up rates. In a 1:1 cluster-randomised controlled trial, we assessed if having the pathology department convey cervical cytology results directly to the invest...

Lithium induces mesenchymal-epithelial differentiation during human kidney development by activation of the Wnt signalling system.
In this study, we isolated mesenchymal cell lines derived from human first trimester kidneys in monolayer culture and investigated their differentiation potential. We found that the mesenchymal cells could convert into osteogenic, but not adipogenic or endothelial lineages. Furthermore, addition of lithium chloride led to MET which was accompanied by increases in epithelial (CDH1) and tubular (ENPEP) markers and downregulation of renal progenitor (SIX2, EYA1, CD133) and mesenchymal markers (HGF, CD24). Prior to phenotypic changes, lithium chloride altered Wnt signalling with elevations in AXIN2, GSK3β phosphorylation ...

Targeted delivery of doxorubicin by CSA-binding nanoparticles for choriocarcinoma treatment.
Abstract Gestational trophoblastic neoplasia (GTN) can result from the over-proliferation of trophoblasts. Treatment of choriocarcinoma, the most aggressive GTN, currently requires high doses of systemic chemotherapeutic agents, which result in indiscriminate drug distribution and severe toxicity. To overcome these disadvantages and enhance the chemotherapeutic efficacy, chondroitin sulfate A (CSA)-binding nanoparticles were developed for the targeted delivery of doxorubicin (DOX) to choriocarcinoma cells using a synthetic CSA-binding peptide (CSA-BP), derived from malarial protein, which specifically binds to the...

Analysis of Cotranslational Polyamine Sensing During Decoding of ODC Antizyme mRNA.
ohmen R Abstract Polyamines are essential poly-cations with vital functions in all cellular systems. Their levels are controlled by intricate regulatory feedback mechanisms. Abnormally high levels of polyamines have been linked to cancer. A rate-limiting enzyme in the biosynthesis of polyamines in fungi and higher eukaryotes is ornithine-decarboxylase (ODC). Its levels are largely controlled posttranslationally via ubiquitin-independent degradation mediated by ODC antizyme (OAZ). The latter is a critical polyamine sensor in a feedback control mechanism that adjusts cellular polyamine levels. Here, we describe an a...

Transcriptional regulation of p57(kip2) expression during development, differentiation and disease.
Abstract p57(kip2) is the most complex member of the CIP/KIP family of cyclin-dependent kinase inhibitors and plays a fundamental role in regulating cell cycle and differentiation during mammalian development. Consistently with a key role for p57(kip2) in the spatial and temporal control of cell proliferation, its expression is fine-tuned by multiple regulatory mechanisms, resulting in a tissue-, developmental phase- and cell type-specific pattern. Moreover, p57(kip2) is an imprinted gene, further supporting the importance of its proper expression dosage. Importantly, misregulation of p57(kip2) expression has been...

Public attitudes toward larger cigarette pack warnings: Results from a nationally representative U.S. sample.
Abstract A large body of evidence supports the effectiveness of larger health warnings on cigarette packages. However, there is limited research examining attitudes toward such warning labels, which has potential implications for implementation of larger warning labels. The purpose of the current study was to examine attitudes toward larger warning sizes on cigarette packages and examine variables associated with more favorable attitudes. In a nationally representative survey of U.S. adults (N = 5,014), participants were randomized to different warning size conditions, assessing attitude toward "a health warn...

SBRT for early-stage glottic larynx cancer-Initial clinical outcomes from a phase I clinical trial.
CONCLUSIONS: We were able to reduce equipotent total fractions of SBRT from 15 to 5 without exceeding protocol-defined acute/subacute toxicity limits. With limited follow-up, disease control appears comparable to standard treatment. We continue to enroll to the 42.5 Gy/5 fx cohort and follow patients for late toxicity.

Emerging Technologies and Techniques in Radiation Therapy.
Abstract The past decade has brought an improved ability to precisely target and deliver radiation as well as other focal prostate-directed therapy. Stereotactic body radiotherapy (SBRT), proton beam radiation, high-dose-rate (HDR) brachytherapy, as well as nonradiotherapy treatments such as cryoablation and high-intensity focused ultrasound are several therapeutic modalities that have been investigated for the treatment of prostate cancer in an attempt to reduce toxicity while improving cancer control. However, high-risk prostate cancer requires a comprehensive treatment of the prostate as well as areas at risk f...

Postoperative Radiation After Radical Prostatectomy.
Abstract A total of 3 randomized clinical trials have demonstrated a significant clinical benefit with adjuvant radiation in patients with high-risk prostate cancer after radical prostatectomy, with each showing improved biochemical control outcomes, and one trial (SWOG 8794) also demonstrating increased overall survival. How broadly these results have informed clinical practice has evolved over time, given the widespread availability of ultrasensitive prostate-specific antigen level testing and increased awareness that the high-risk patients are not a uniform cohort. In this review, we discuss the evidence from p...

Nonsteroidal Anti-inflammatory Drugs and Endometrial Carcinoma Mortality and Recurrence.
CONCLUSIONS: In this study, use of NSAIDs was associated with increased endometrial carcinoma-specific mortality, especially in patients with type I tumors. Barring a clear biologic mechanism by which NSAIDs would increase the risk of cause-specific mortality, cautious interpretation is warranted.
