The Removal of Analgesics and Antibiotics by Laccases
Laccase is an enzyme belonging to the class of oxidoreductases. It catalyzes the four-electron oxidation of a substrate in the presence of molecular oxygen as a co-substrate to form water. The removal of pharmaceutically active substances by enzymes such as laccases has received considerable attention. Laccases were evaluated for their efficacy in degrading pharmaceutical substances across various categories, including analgesics, antibiotics, antiepileptics, antirheumatic drugs, cytostatics, hormones, anxiolytics, and sympatholytics.

Solubility of Oxygen and Hydrogen in Water
Produced by photosynthesis, oxygen (O2) is a fundamentally important gas in biological systems, playing roles as a terminal electron receptor in respiration and in host defence through the creation of reactive oxygen species (ROS). Hydrogen (H2) plays a role in metabolism for some organisms, such as at thermal vents and in the gut environment, but has a role in controlling growth and development, and in disease states, both in plants and animals.

Zinc-Dependent Histone Deacetylases in Lung Endothelial Pathobiology
The intricate dynamics of endothelial cells (ECs), form a monolayer along blood vessel lumens and act as a semi-selective barrier between blood and interstitial spaces. In instances of inflammatory or toxic events, compromise of the lung EC barrier may lead to pulmonary edema, a crucial aspect of acute lung injury (ALI) and acute respiratory distress syndrome (ARDS). The nuanced control of EC functions involves epigenetic mechanisms, particularly those mediated by zinc-dependent histone deacetylases (HDACs). Representing the largest HDAC subgroup, zinc-dependent HDACs are activated by Zn2+ and play a pivotal role in epigenetic regulation by modifying chromatin structure and deacetylating non-histone proteins.

Family in Medieval Society
One of the periods with the greatest social, cultural, and religious changes was, without a doubt, the European medieval period. The concept of “Family” was one of the fields that gradually evolved, from individuals who shared the same biological lineage, to members of the same “House”. One of the ways to study the concept of “Family” in ancient periods is through a bioarchaeological perspective, where both anthropology and genetics have proven to be essential disciplines for studying “Families”. Through burial rituals, observing whether the graves were single or multiple, as is carried out in the study of human remains, it discusses the profound contribution of anthropology to the “Family” investigation, through mobility studies, the investigation of biological sex, observing certain congenital anomalies or, even, the study of certain ancient infectious diseases. Concerning genetics, the study of bones or teeth allows us to determine whether individuals were from the same close family or if they belonged to the same lineage through the maternal and paternal sides, being one of the only scientific ways of proposing social relationships between individuals, such as that created through adoption.
