G-Quadruplex DNAzyme-Based Biocatalysis Combined with an Intelligent Electromagnetic-Actuated Microfluidic Chip for Tetracycline Detection.

In this study, we present an intelligent electromagnetic-actuated microfluidic chip integrated with a G-quadruplex DNAzyme-based biocatalysis platform for rapid and sensitive tetracycline (TC) detection. In this sensing system, TC significantly quenches fluorescent magnetic carbon dots (M-CDs) via the internal filtration effect and dynamic quenching (the excitation and emission wavelength at 350 and 440 nm, respectively). Then, the G-quadruplex on the M-CDs-Aptamer is exposed and bound with hemin to form hemin-G-quadruplex DNAzyme, catalyzing the conversion of 3,3',5,5'-tetramethylbenzidine to produce blue color.

"That's not fair on my kid": Carers' perspectives on sport participation and experiences for children in out-of-home care.

Children in out-of-home care participate in less organised sport than children from other household structures, potentially reducing opportunities for improvements in social, developmental, and health outcomes. Despite this, little is known about barriers and facilitators of sport participation for children in care. We aimed to explore carers' perspectives on the influences on children in care's participation and experiences in organised sport.

Spreading the Word: Communicating Evidence-Based Guidelines About Turner Syndrome to Patients, Parents, Providers, and Payors.

Given the overwhelming volume of medical information, medical guidelines play a key role in informing clinicians and payors and guidelines directly affect how patients, and their families will be treated. In this review, we describe the production cycle of international guidelines for Turner syndrome (TS) and promote the timely and proactive dissemination of these guidelines. We encourage deliberate adoption of an updated standard of care by providers, payors, patients and their families, and professional organizations.

Characterization of the immune cell profile in metastatic nasopharyngeal carcinoma treated with chemotherapy and immune checkpoint inhibitors.

Nasopharyngeal carcinoma (NPC) is an Epstein-Barr virus (EBV)-associated cancer, and immune checkpoint inhibitors (ICIs) have shown efficacy in its treatment. The combination of chemotherapy and ICIs represents a new trend in the standard care for metastatic NPC. In this study, we aim to clarify the immune cell profile and related prognostic factors in the ICI-based treatment of metastatic NPC.

Seroprevalence, incidence estimates, and environmental risk factors for dengue, chikungunya, and Zika infection amongst children living in informal urban settlements in Indonesia and Fiji.

Background: The burden of Aedes aegypti-transmitted viruses such as dengue, chikungunya, and Zika are increasing globally, fueled by urbanization and climate change, with some of the highest current rates of transmission in Asia. Local factors in the built environment have the potential to exacerbate or mitigate transmission.

Methods: In 24 informal urban settlements in Makassar, Indonesia and Suva, Fiji, we tested children under 5 years old for evidence of prior infection with dengue, chikungunya, and Zika viruses by IgG serology.
