The view of Hong Kong parents on secondary use of dried blood spots in newborn screening program.

Background: Residual dried blood spots (rDBS) from newborn screening programmes represent a valuable resource for medical research, from basic sciences, through clinical to public health. In Hong Kong, there is no legislation for biobanking. Parents' view on the retention and use of residual newborn blood samples could be cultural-specific and is important to consider for biobanking of rDBS.

Noninvertible Global Symmetries in the Standard Model.

We identify infinitely many noninvertible generalized global symmetries in QED and QCD for the real world in the massless limit. In QED, while there is no conserved Noether current for the U(1)_{A} axial symmetry because of the Adler-Bell-Jackiw anomaly, for every rational angle 2πp/N, we construct a conserved and gauge-invariant topological symmetry operator. Intuitively, it is a composition of the axial rotation and a fractional quantum Hall state coupled to the electromagnetic U(1) gauge field.

Endotracheal Tube Kinking in the Prone Position during Pediatric Neurosurgery: A Case Report.

The prone position presents several concerns for the pediatric anesthesiologist, such as prevention of pressure related injuries, avoidance of undetected line infiltration, proper airway securement to inhibit unanticipated extubation, and limited access to the patient in critical events. However, the possibility of endotracheal tube kinking in pediatric patients is rarely discussed in the multitude of concerns about prone procedures. Here, we present a case report detailing the anesthetic management of a patient that experienced endotracheal tube kinking in the prone position during a posterior fossa mass resection.

Antibody drug conjugates (ADCs) are an emerging therapeutic class used in Cancer to deliver targeted therapy. ADCs are composed of three components, an antibody, a chemical linker and a payload which must be chosen carefully to be effective and safe.

Establishing a National Engagement Strategy for Recruiting Asian Americans and Other Minorities into Biomedical Research.

Background: The All of Us Research Program seeks to advance precision medicine and reduce health disparities by recruiting people in demographic categories that are underrepresented in biomedical research. Asian Americans, Native Hawaiians and Pacific Islanders are the most understudied of all racial/ethnic groups in the United States. We propose a national engagement strategy for the recruitment of Asian Americans, Native Hawaiians and Pacific Islanders into biomedical research using a community-based participatory research approach.

Fluorescent Imaging and Sorting of High-Lipid-Content Strains of Green Algae by Using an Aggregation-Induced Emission Luminogen.

Microalgae-based biofuels are receiving attention at the environmental, economic, and social levels because they are clean, renewable, and quickly produced. The green algae has been extensively studied in research laboratories and the biofuel industry as a model organism to increase lipid production to be cost-effective in commercial production. In this work, we utilized a lipid-droplet-specific luminogen with aggregation-induced emission (AIE) characteristics to increase the lipid production of by fluorescent imaging and sorting of those algal cells with large and rich lipid droplets for subculturing.

Similarity Maps for Ventricular Arrhythmia Classification.

Ventricular arrhythmias are the primary arrhythmias that cause sudden cardiac death. In current clinical and preclinical research, the discovery of new therapies and their translation is hampered by the lack of consistency in diagnostic criteria for distinguishing between ventricular tachycardia (VT) and ventricular fibrillation (VF). This study develops a new set of features, similarity maps, for discrimination between VT and VF using deep neural network architectures.

Antibody stabilization for thermally accelerated deep immunostaining.

Antibodies have diverse applications due to their high reaction specificities but are sensitive to denaturation when a higher working temperature is required. We have developed a simple, highly scalable and generalizable chemical approach for stabilizing off-the-shelf antibodies against thermal and chemical denaturation. We demonstrate that the stabilized antibodies (termed SPEARs) can withstand up to 4 weeks of continuous heating at 55 °C and harsh denaturants, and apply our method to 33 tested antibodies.
