Unveiling the role of saltmarshes as coastal potassium sinks: A perspective from porewater-derived potassium exchange.

Saltmarshes serve as repositories for various metal species, primarily due to vegetation removal and mineralization processes. However, the significance of potassium (K), one of the three major nutrients (nitrogen, phosphorus, and K) essential for plant growth, has often been overlooked, particularly in the context of saltmarshes where the mechanisms of K transport via porewater exchange remain poorly understood. To address this knowledge gap, we conducted field observations and laboratory analysis, and developed a Rn mass balance model to quantify K fluxes via porewater exchange under physical, biological, and anthropogenic drivers.

Polycyclic aromatic hydrocarbons (PAHs) are known to have toxic effects on fish. In this study, we examined the effects of benz[a]anthracene (BaA), a type of PAH, on fish liver metabolism. Nibbler fish () were intraperitoneally injected with BaA (10 ng/g body weight) four times over a 10-day period.

Northern blotting is a common technique in RNA biology, allowing to detect and quantify RNAs of interest following separation by gel electrophoresis, transfer to a membrane, and hybridization of specific anti-complementary labelled probes. In this chapter, we describe our protocol for efficient RNA extraction from yeast, separation on agarose gel, and capillary transfer to a membrane. We provide two different methods for strand-specific detection of several types of RNAs using oligonucleotide probes, the first using radioactive P-labelled probes, the second based on nonradioactive digoxigenin-labelled probes.

Objective: The study aimed to assess the impact of postoperative radioactive iodine (RAI) therapy on parathyroid function in patients who underwent total or subtotal thyroidectomy for differentiated thyroid cancer (DTC).
Methods: Data from 150 patients treated with RAI for DTC and 76 patients with low-risk DTC not receiving RAI were retrospectively analyzed. Clinical characteristics, preoperative and 1-month postoperative biochemical parameters, and adjusted calcium, phosphorus, parathyroid hormone (PTH), and 25-hydroxyvitamin D3 (25-OH-D) levels at 3 months, 1 year, 3 years, and 5 years post-RAI (or in the low-risk group) were recorded.

Article Synopsis
- The study looked at how well Phosphorus-32 P treatment worked for 17 older patients with a specific type of blood cancer that is not caused by a gene called Philadelphia.
- Most patients improved after treatment, and some had to get multiple doses because the first one wasn't enough.
- The researchers found that there were some side effects, like anemia, but there were no serious problems like developing leukemia.
