A 72-year-old man with advanced locally invasive basal cell carcinoma of the forehead failed several pretreatments including surgery and radiation. MRI was not feasible because of the presence of facial implants. CT scan did not provide clear evidence of vital/avital tumor sites as a result of slow progression and previous radiation treatments.

- The study investigated the sound patterns of a newly examined dolphin population in the Mediterranean, focusing on how environmental and social factors influence their vocalizations.
- Findings showed that dolphins emitted more whistles and clicks when in larger groups or with calves present, with specific acoustic features changing based on behavior and environmental conditions.
- The research revealed that dolphins have a flexible acoustic communication system, affected by social interactions and habitat conditions, highlighting the need for more localized studies on their communication.
Marine bioconstructions and their ecological functions are increasingly threatened by compounded natural disturbances and direct and indirect impacts of anthropogenic activities. Through a manipulative experiment in the field, we assessed the response of intertidal biogenic patches built by the honeycomb worm, Sabellaria alveolata, to combined disturbances. Repeated battering events, simulating those associated with waves, were applied on intact or previously damaged bioconstructions, mimicking those impacted by harvesting of infaunal organisms.

Use of L-asparaginase to promote asparagine starvation in solid tumors with low ASNS levels, such as pancreatic ductal adenocarcinoma (PDAC), is a rationale treatment strategy.
