Article Synopsis
- Phosphorus (P) is vital for ecosystems, but human activities can cause either too much or too little in coastal waters, leading to ecological problems like eutrophication and algal blooms.
- In Hangzhou Bay, a study revealed that particulate phosphorus (PTP) levels were significantly higher than dissolved inorganic phosphorus (DIP), influenced by seasonal sediment resuspension and regional variations.
- The research found that fine-grained suspended particulate matter (SPM) contained 3000 tons of bioavailable P, which can contribute to harmful algal blooms, emphasizing the need to understand P dynamics in turbid coastal waters for better management of eutrophication.
Article Synopsis
- Self-collection of saliva samples has gained popularity, especially during the COVID-19 pandemic, but studies on its effectiveness for detecting respiratory pathogens are lacking.
- In a study involving 469 patients, the effectiveness of nasopharyngeal swabs, oropharyngeal swabs, and saliva samples was compared, with nasopharyngeal swabs showing the highest detection rate for respiratory pathogens.
- The research concluded that while nasopharyngeal swabs are reliable, saliva samples are easier to collect and may be beneficial in emergency situations, with a combination of sample types potentially improving detection rates.
Background: Cyclophilin A (CyPA) is a potential mediator of inflammation. We assessed the predictive value of the first-trimester maternal serum CyPA concentrations for complicated pregnancy.
Methods: The first-trimester serum CyPA concentrations were quantified in 100 women with normal pregnancy and in 351 women with complicated pregnancy, including 102 pre-eclampsia women, 131 gestational hypertension (GH) women and 118 gestational diabetes mellitus (GDM) women.
