Imagine, Discover, Inspire: Proceedings of the 4th International Conference of the Trisomy 21 Research Society.

Down syndrome (DS) or trisomy 21 (T21) is present in a significant number of children and adults around the world and is associated with cognitive and medical challenges. Through research, the T21 Research Society (T21RS), established in 2014, unites a worldwide community dedicated to understanding the impact of T21 on biological systems and improving the quality of life of people with DS across the lifespan. T21RS hosts an international conference every two years to support collaboration, dissemination, and information sharing for this goal.

Comprehensive histopathological analysis of gastric cancer in European and Latin America populations reveals differences in PDL1, HER2, p53 and MUC6 expression.

Introduction: Gastric cancer (GC) burden is currently evolving with regional differences associated with complex behavioural, environmental, and genetic risk factors. The LEGACy study is a Horizon 2020-funded multi-institutional research project conducted prospectively to provide comprehensive data on the tumour biological characteristics of gastroesophageal cancer from European and LATAM countries.

Material And Methods: Treatment-naïve advanced gastroesophageal adenocarcinoma patients were prospectively recruited in seven European and LATAM countries.

Motivation of nursing undergraduate program entrants: A scoping review protocol.

Motivation is of great importance in the teaching-learning process, because motivated students seek out opportunities and show interest and enthusiasm in carrying out their tasks. The objective of this review is to identify and present the information available in the literature on the status quo of motivation among nursing program entrants. This is a qualitative scoping review study, a type of literature review designed to map out and find evidence to address a specific research objective, following the Joanna Briggs Institute methodology.

Basic Science and Pathogenesis.

Background: At least one-third of the identified risk alleles from Genome Wide Association Studies of Alzheimer's disease (AD) are involved in lipid metabolism, lipid transport, or direct lipid binding. BIN1 which is also known as Amphiphysin 2; and PICALM which are involved in phosphoinositide metabolism and binding rank just below the highest risk gene variant of Apolipoprotein E (ApoEε4), a cholesterol and phospholipid transporter. In addition to genetic variants, lipidomic studies have reported severe metabolic dysregulation in human autopsy brain tissue, CSF, blood and multiple mouse models of AD.

Clinical Manifestations.

Background: Families with a history of Alzheimer's Disease (AD) may have a genetic predisposition that raises the risk of developing the condition. However, not all members of these families can undergo genetic testing. Thus, this study aims to evaluate specific cognitive changes, neuropsychiatric symptoms (NPS), and personality traits that may act as early indicators of AD in family members compared to controls.
