Loading drops with discrete objects, such as particles and cells, is often necessary when performing chemical and biological assays in microfluidic devices. However, random loading techniques are inefficient, yielding a majority of empty and unusable drops. We use deformable particles that are close packed to insert a controllable number of particles into every drop. This provides a simple, flexible means of efficiently encapsulating a controllable number of particles per drop.

Validation Status of Electronic Sphygmomanometers in China: A National Survey.

Hypertension

January 2025

Clinical Research Institute, Institute of Advanced Clinical Medicine, Peking University, Beijing, China (X.Z., W.X., Y.W.).

Background: Although the information on the validation status of electronic sphygmomanometer (ES) devices in use in health care institutions and households is much more clinically relevant than that of ES models available on the market, it remains insufficient.

Methods: A national survey was conducted across all administrative regions of mainland China to assess the validation status of ESs. Fifty-eight cities were selected with stratification by municipality, provincial capital, and other cities, and health care institutions and households in each city were chosen by convenience to identify ES devices in use according to the study protocol.

The EFSA Panel on Food Contact Materials (FCM) assessed the safety of the recycling process NGR LSP (EU register number RECYC328). The input is hot washed and dried poly(ethylene terephthalate) (PET) flakes mainly originating from collected post-consumer PET containers, with no more than 5% PET from non-food consumer applications. The flakes are dried (step 2), melted in an extruder (step 3) and decontaminated during a melt-state polycondensation step under high temperature and vacuum (step 4).

Background And Aim: The high rate of tumor growth results in an increased need for amino acids. As solute carriers (SLC) transporters are capable of transporting different amino acids, cancer may develop as a result of these transporters' over-expression due to their complex formation with other biological molecules. Therefore, this review investigated the role of SLC transporters in the progression of cancer.

A discrete choice experiment on Chinese parents' preferences of vaccine schedules against six childhood infectious diseases.

Vaccine X

January 2025

National Key Laboratory of Intelligent Tracking and Forecasting for Infectious Diseases, National Immunization Program, Chinese Center for Disease Control and Prevention, Beijing, China.

Background: China's Expanded Program on Immunization (EPI) provides vaccinations against 12 vaccine preventable diseases (VPDs) at no cost to families. For some VPDs, parents may opt to substitute equivalent non-program vaccines, including combination vaccines, for EPI vaccines; substitute vaccines must be paid for by the family. Although parents have several choices for vaccinating their children, their preferences for vaccines and immunization schedules have not been systematically evaluated.
