Temperature and nutrient concentrations were measured during a mixed bloom of Noctiluca scintillans and Gymnodinium catenatum in La Paz Bay, Gulf of California. Under laboratory conditions, we offered three concentrations of G. catenatum (312, 625, or 1015 cells mL–1) to 0.53 N. scintillans cells mL–1 to study predation rates. Experiments were carried out with 750 mL of culture during a fiveday period. Sea surface temperature clearly showed a transitional period from colder to warmer water during the bloom. Field and laboratory data showed that N. scintillans fed on G. catenatum. During the trial, more than 70% of N. scintillans cells contained G. catenatum cells in their vacuoles. Ingestion rates varied; the highest ranged from 30 to 40 G. catenatum cells h–1 in each N. scintillans cell. A clear relation to the concentration of the diet was not evident. Low values of 1 to 3 G. catenatum cells h–1 in each N. scintillans cell were typical at the end of the trial. Noctiluca scintillan...

Dinoflagellates are microalgae that are associated with the production of many marine toxins. These toxins poison fish, other wildlife and humans. Dinoflagellate-associated human poisonings include paralytic shellfish poisoning, diarrhetic shellfish poisoning, neurotoxic shellfish poisoning, and ciguatera fish poisoning. Dinoflagellate toxins and bioactives are of increasing interest because of their commercial impact, influence on safety of seafood, and potential medical and

Access to medical equipment is an essential component of the healthcare infrastructure. Due to the high manufacturing cost, low- and middle-income countries rely on donations from high-resource settings to meet their demand for medical equipment. International organizations such as the World Health Organization have prescribed guidelines for sustainable donations. A few research studies have assessed current donation practices' compliance with new and used medical equipment. This study aims to investigate commonly recurring challenges and compile practical recommendations for medical equipment donation programs in low- and middle-income countries. To validate the findings from the literature review, semi-structured interviews were conducted with three different types of recipients across Pakistan and Sierra Leone. There are some obstacles affecting this sustainable medical equipment donation program. These hurdles can be overcome by strict compliance with the official World Health Organization guidelines, empowering the recipient through communication and policy, establishing vital metrics, developing sustainable long-term donor-recipient relationships, and by comprehensive evaluation of the impact of all the stakeholders in the medical equipment ecosystem. The study concludes that well-established guidelines and policies are critical to successful medical equipment donation programs.
