Membrane fouling is a common and complex challenge with cell culture perfusion process in biopharmaceutical manufacturing that can have detrimental effects on the process performance. In this study, we evaluated a method to calculate the hollow fiber membrane resistance at different time points for water and supernatant. In addition, the number of subvisible particles of < 200 nm.

However, there is limited data available in Pakistan. Therefore, we analyzed to examine the incidence, clinicopathological features, treatments, and outcomes of SRCC in colorectal cancer cases in Pakistan.

- The paper assesses fluoride pollution in drinking water sources in Swabi, Pakistan, highlighting its severe impact on human health, particularly fluorosis.
- It involved collecting and analyzing 126 groundwater and 18 surface water samples, revealing that 72.2% of groundwater samples exceeded WHO's safe fluoride limit.
- The study identified key factors contributing to fluoride enrichment in the aquifer, including natural processes and human activities, emphasizing the need for improved water management to protect local communities from health risks associated with high fluoride levels.
