Article Synopsis
- Indium phosphide (InP) quantum dots (QDs) are being explored as safer alternatives to cadmium-based QDs, but their stability can be a major issue.
- A thick ZnS shell is commonly used to protect InP cores from degradation and to improve luminescence; however, the difference in lattice structure between InP and ZnS can lead to defects that reduce efficiency.
- This research outlines a new method to create InP QDs with improved stability and luminescence by managing the shell growth process; the resulting QDs exhibit a photoluminescence quantum yield of about 90%, showcasing potential for applications in eco-friendly technologies.
Article Synopsis
- The study focuses on improving methods for imputing missing data using Classification and Regression Trees (CART), highlighting the importance of having complete datasets for analysis.
- A new perspective is introduced through resampling algorithms, and several existing CART imputation methods are compared to find the most accurate among various scenarios.
- Results indicate that the best imputation technique varies based on variable correlation, with specific recommendations for handling ordinal categorical and quantitative variables under different missing data conditions.
Background: Probiotic treatments might contribute to the prevention of ventilator-associated pneumonia (VAP). Due to its unclear clinical effects, here we intend to assess the preventive effect and safety of probiotics on intensive care unit (ICU) patients.
Methods: Eligible randomised controlled trials were selected in databases until 30 September 2019.
We assessed the occurrence of nonylphenol (NP) and bisphenol A (BPA) in tap water supplied through polyvinyl chloride (PVC), stainless steel, and galvanized pipes. Water samples were collected from selected households in Taipei and Kaohsiung (Northern and Southern Taiwan, respectively) in different seasons to elucidate the effects of pipeline materials and ambient temperatures on NP and BPA concentrations in tap water. We detected higher concentrations of NP in tap water from households using PVC pipes (64-195 ng/L) than from those using stainless steel pipes (17-44 ng/L) and galvanized pipes (27-96 ng/L).

Methods: Immunohistoehemistry was used to detect the expressions of the active form of GSK-3- pGSK-3α/β (Tyr279/216) and its downstream moleculor XIAP proteins in 50 cholangiocarcinoma tissues and 20 normal bile duct tissues.
Results: The positive rates of pGSK-3α/β (Tyr279/216) and XIAP were 62.
Article Synopsis
- This study examined the impact of prenatal environmental tobacco smoke (ETS) on genetic damage and negative birth outcomes in newborns born to mothers in Central Taiwan.
- Mothers were divided into two groups: nonsmokers and those exposed to ETS, with genetic damage in newborns measured using a comet assay on cord blood samples.
- Results showed that infants exposed to ETS had significantly higher DNA damage scores and adverse outcomes, including lower birth weight, shorter length, and smaller head circumference compared to those without ETS exposure.
