Biodiversity of microorganisms in the Baltic Sea: the power of novel methods in the identification of marine microbes.

Until recently, the data on the diversity of the entire microbial community from the Baltic Sea were relatively rare and very scarce. However, modern molecular methods have provided new insights into this field with interesting results. They can be summarized as follows.

Multi-biomarker response of cyanobacteria Synechocystis salina and Microcystis aeruginosa to diclofenac.

The cyanobacterial response to pharmaceuticals is less frequently investigated compared to green algae. Pharmaceuticals can influence not only the growth rate of cyanobacteria culture, but can also cause changes at the cellular level. The effect of diclofenac (DCF) as one of the for cyanobacteria has been rarely tested, and DCF has never been applied with cellular biomarkers.

An Asymptomatic, Ectopic Mass as a Presentation of Adrenocortical Carcinoma Due to a Novel Germline p.Phe338Leu Tetramerisation Domain Variant.

Adrenocortical carcinoma (ACC) is a rare cancer in childhood. ACC is frequently associated with germline variants, with founder effects especially due to the p.Arg337His mutation.

Uptake and trophic transfer of selenium into phytoplankton and zooplankton of the southern Baltic Sea.

Selenium (Se) is an essential trace element and displays a narrow range of concentration between essentiality and toxicity. Se plays an important role in ameliorating mercury toxicity in organisms. Despite this there are only a few reports concerning Se concentration in plankton, the first link in the trophic chain that determines the uptake and transfer of Se to subsequent trophic levels.

Oral Cavity Cancer Tissues Differ in Isotopic Composition Depending on Location and Staging.

The aim of this paper was to characterise the isotopic composition of oral squamous cell carcinoma (OSCC) specimens of different areas of the oral cavity. Secondly, we assessed whether there was a correlation between clinical stages of OSCC and isotopic abundance. The IRMS procedure was performed on 124 samples derived from 31 patients with OSCC of 15 N and 13 C to assess the isotopic composition.
