Common dolphin's shipping noise risk assessment on the Portuguese coast.

Ocean noise generated by human activities at sea has been increasing over the decades, affecting marine ecosystems. Ship traffic flow between the Mediterranean or South Atlantic and northern Europe makes the coast of Portugal one of the most intense shipping highways on a global scale. Among the cetaceans of the coast of Portugal, the common dolphin (Delphinus delphis) was selected as a target species.

Predictors of Success in a Graduate, Entry-Level Professional Program: From Admissions to Graduation.

Introduction: Admission to health professional programs (HPPs) in Canada is competitive. The purpose of this study is to evaluate how factors identifiable by the admissions package may predict incidences of academic concerns in one physiotherapy program in Canada.

Review Of Literature: Previous literature has identified many concepts that contribute to "academic success.

Difference in Physiotherapy Students' Training and Objective Structured Clinical Exam Performance Before and During COVID-19.

Purpose: The Objective Structured Clinical Examination (OSCE) and station examinations, in general, have been widely utilized in health professional programmes to evaluate students' clinical performance prior to advancing to a clinical placement. The COVID-19 pandemic impacted student preparation and implementation of our programme's OSCEs. The impact on changes in student OSCE performance due COVID-19 has not been well studied.

Industrial and academic approaches to the search for alternative melatonin receptor ligands: An historical survey.

The search for melatonin receptor agonists formed the main part of melatonin medicinal chemistry programs for the last three decades. In this short review, we summarize the two main aspects of these programs: the development of all the necessary tools to characterize the newly synthesized ligands at the two melatonin receptors MT and MT, and the medicinal chemist's approaches to find chemically diverse ligands at these receptors. Both strategies are described.

Binding and unbinding of potent melatonin receptor ligands: Mechanistic simulations and experimental evidence.

The labeled ligand commonly employed in competition binding studies for melatonin receptor ligands, 2-[I]iodomelatonin, showed slow dissociation with different half-lives at the two receptor subtypes. This may affect the operational measures of affinity constants, which at short incubation times could not be obtained in equilibrium conditions, and structure-activity relationships, as the K values of tested ligands could depend on either interaction at the binding site or the dissociation path. To address these issues, the kinetic and saturation binding parameters of 2-[I]iodomelatonin as well as the competition constants for a series of representative ligands were measured at a short (2 h) and a long (20 h) incubation time.
