Background: A novel 13-valent pneumococcal conjugate vaccine (PCV13-TT) has been widely used in China since its licensure in 2019. The prelicensure pivotal clinical study (PCV13-002) showed strong immune responses against 13 serotypes with PCV13-TT using two different 3P + 1 schedules starting at either 2 (PCV13-2M) or 3 months (PCV13-3M) of age.

Methods: To assess antibody persistence, healthy Chinese toddlers from PCV13-002 were recalled for blood collection at 1 and 2 years post booster dose.

Article Synopsis
  • - Detecting acetone in breath can help noninvasively diagnose diabetes, but current methods struggle with high humidity and low concentration (parts per billion).
  • - A new ultrasensitive acetone sensor using K/Sn-CoO porous microspheres has been developed, achieving a detection limit of 100 ppb with good selectivity and repeatability, even in humid conditions.
  • - The sensor's improved sensitivity is due to better oxygen adsorption and interaction with acetone molecules, which allows it to differentiate between diabetic and healthy individuals effectively.

Developing fast, accurate and sensitive triethylamine gas sensors with low detection limits is paramount to ensure the safety of workers and the public. However, sensors based on single metal oxide materials still suffer from drawbacks such as low response sensitivity and long response and recovery times. To address these challenges, in this work, a series of mesoporous CdO/CdGaO microspheres were synthesized.

Objective: Waste sorting has received considerable attention in recent decades. However, research on the mechanisms underlying the relationships among cultural worldview, environmental risk perception, and waste sorting is rather scarce. This study aims to explore the cultural worldviews, environmental risk perception, and waste sorting among urban Chinese and their mechanisms.

The performance of lead halogen perovskite is often closely related to its crystal structure. However, the chemical and optoelectronic properties of tetragonal phase single crystal MAPbCl3 (SC T-MAPbCl3) are rarely reported. In this study, we synthesized SC T-MAPbCl3 with the P4/mcc (124) space group by a modified inverse temperature crystallization (M-ITC) method.

Photodetectors play a key role in the military, aerospace, communications, bio-imaging, etc. In this study, we fabricate photodetector devices based on (CH3NH3)2FeCuI4Cl2 (MA2FeCuI4Cl2) and (CH3NH3)2InCuI6 (MA2InCuI6) for the first time. We find that the device based on MA2InCuI6 is highly selective for ultraviolet light (880 nA mW-1) and shows high anti-interference for visible-light (20-50 nA mW-1).

The clinical use of the steroidal aromatase inhibitor Formestane (4-hydroxandrostenedione, 4-OHA) in the treatment of advanced ER+ breast cancer has been discontinued, and therefore, interest in this remarkable drug has vanished. As a C-19 sterol, 4-OHA can undergo extensive intracellular metabolism depending on the expression of specific enzymes in the corresponding cells. We used the metabolites 4β-hydroxyandrosterone, 4β-hydroxyepiandrosterone and its 17β-reduced derivative as standards for the proof of catalytic activity present in the cell culture medium and expressed by the isolated enzymes.

The semi-transparent solar cells are promising to be applied in building integrated photovoltaic (BIPV) and tandem solar cells. In this study, we fabricate semi-transparent and stable solar cells for BIPV by utilizing a poly (ethylene oxide) electrolyte and controlling the size of TiO nanoparticles and the thickness of the TiO film. The power conversion efficiency of the semi-transparent (over 50% transmittance at 620-750 nm) and quasi-solid solar cells is 5.
