Neonatal Abandonment and Hydrocephalus in Antillean Manatees (): Is There a Causal Relationship?

Manatees are semi-social animals, with the mother-calf relationship being considered long-lasting for the species. However, some events lead to the separation of this pair. Orphaned manatee calves can be adopted by other females of the same species.

Short Supply of High Levels of Guanidine Acetic Acid, Alters Ovarian Artery Flow and Improves Intraovarian Blood Perfusion Area Associated with Follicular Growth in Sheep.

Guanidinoacetic acid (GAA), a precursor of creatine, has a recognized effect on ruminant performance when used as a dietary supplement. However, its impact on reproductive response remains to be elucidated. Therefore, this study aimed to contribute initially to this area by supplementing the diets of ewes with a high dose of GAA, evaluating its effects on reproductive response.

Data Platform for Animal Mortality Information System (DATASIMA): Monitoring Companion Animal's Euthanasia Causes in City of João Pessoa, Brazil.

The literature regarding causes of animal mortality varies greatly in how it evaluates and describes reasons for euthanasia, showing a clear need for tools to identify, standardize, and map diseases. This study describes the application of the Animal Mortality Information System Database (DATASIMA) to monitoring and georeferencing animal mortality. An observational study was conducted on the dogs and cats euthanized at the Municipal Center for Environmental and Zoonotic Surveillance in João Pessoa, Paraíba.

Flexibility between immersion and distancing: Relationship with depressive symptoms and therapeutic alliance.

Objectives: High levels of change are linked to the flexibility between immersion and distancing, as well as to higher levels of therapeutic alliance. This study aims to explore the evolution of flexibility between immersion and distancing throughout the entire therapeutic process and its relationship with therapeutic alliance and depressive symptoms in a clinical case.

Method: We analyzed five sessions of a good outcome case of depression undergoing cognitive-behavioral therapy.

The Melanocyte and Nerve Fiber Cross-Talk, Facilitated Also by Semaphorin-4A, Enhances UV-B-Induced Melanogenesis.

Epidermal melanocytes form synaptic-like contacts with cutaneous nerve fibers, but the functional outcome of these connections remains elusive. In this pilot study we used our fully humanized re-innervated skin organ culture model to investigate melanocyte-nerve fiber interactions in UV-B-induced melanogenesis. UV-B-irradiation significantly enhanced melanin content and tyrosinase activity in re-innervated skin compared to non-innervated controls, indicating that neuronal presence is essential for exacerbating pigmentation upon UV-B irradiation in long-term culture.
