This retrospective study of neoplasia in prosimians in human care reports histologically diagnosed cases from the archives of a nondomestic species pathology service between 1995 and 2022, primarily submitted from zoological institutions. To date, the only prior retrospective study of neoplasia in prosimians, published in 2009, was conducted with cases from a single institution specializing in prosimian noninvasive research and care. In the present study, a total of 153 neoplasms from 109 individuals were identified in the pathology service archives.

Mutations in more than 50 different genes cause primary ciliary dyskinesia (PCD) by disrupting the activity of motile cilia that facilitate mucociliary transport (MCT). Knowledge of PCD has come from studies identifying disease-causing mutations, characterizing structural cilia abnormalities, finding genotype-phenotype relationships, and studying the cell biology of cilia. Despite these important findings, we still lack effective treatments and people with PCD have significant pulmonary impairment.

Acute invasive fungal sinusitis (AIFS) is an aggressive disease with significant mortality and morbidity. Surgical debridement is a mainstay of treatment. However, orbital involvement may limit its efficacy and is an independent risk factor for mortality.

Trade-offs resulting from the high demand of offspring production are a central focus of many subdisciplines within the field of biology. Yet, despite the historical and current interest on this topic, large gaps in our understanding of whole-organism trade-offs that occur in reproducing individuals remain, particularly as it relates to the nuances associated with female reproduction. This volume of Integrative and Comparative Biology (ICB) contains a series of papers that focus on reviewing trade-offs from the female-centered perspective of biology (i.

Article Synopsis
  • The report examines clinical, genetic, and biochemical characteristics of individuals with a confirmed congenital disorder of glycosylation (CDG) participating in the FCDGC Natural History cohort after five years of study.
  • A total of 333 subjects were enrolled, with 280 having available genetic data; this included a nearly even split between males and females, with ages ranging from infancy to 71 years.
  • The study found developmental delays to be the most common symptom leading to diagnosis, occurring in 77% of participants, with an average delay of 2.7 years from symptom onset to diagnosis, and nearly all individuals displaying some developmental differences at the time of enrollment.
