C‐cell differentiation in the wall of an aberrant ultimobranchial sinus in the thyroid gland of an old rat

Veterinary Medicine and Science, 2023
Background In mammals, the thyroid gland possesses two types of endocrine cells, follicular cells and C cells, which have different functions but share a similar endodermal origin (although from different regions of the primitive pharynx).

Optimizing Alternating Current Electrical Stimulation Parameters to Enhance Osteoblasts Differentiation. [PDF]

Biofactors
Alternating current stimulation at 10 Hz and 500–750 mV/mm optimizes osteoblastic differentiation, viability, and morphological maturation. This study establishes critical parameters for utilizing electrical signaling in bone tissue engineering, offering a promising strategy to accelerate bone regeneration and early‐stage cell development.

Risk Stratification of Thyroid Nodules 10 mm in Diameter or Less: Strength and Pitfalls of the Ultrasonographic Assessment From a Cross-Sectional Study. [PDF]

Int J Endocrinol
Background: The selection of thyroid nodules ≤ 10 mm requiring characterization and treatment should be improved, as extensive detection, cytological assessment, and surgery of small and well‐differentiated thyroid carcinoma are not cost‐effective. Aim: To assess the accuracy of algorithms and ultrasonographic characteristics in selecting actual high ...

Evaluation of Lamendin’s age-at-death estimation method in a documented osteological collection (La Plata, Argentina)

Forensic Science International: Reports, 2020
Age estimation is one of the main biological parameters to be determined for constructing an individual biological profile. In contexts where bones are poorly preserved, the use of teeth becomes relevant.

Comparison between clinical evaluations and laboratory findings and the impact of biofilm on antimicrobial susceptibility in vitro in canine otitis externa

Veterinary Dermatology, Volume 34, Issue 6, Page 586-596, December 2023., 2023
Background – In clinical practice, the diagnosis of otitis externa (OE) normally is based on otoscopic examination and cytological findings, followed by empirical treatment with topic drugs. Biofilm‐producing bacteria are frequently present in OE, even if its presence is often underdiagnosed. Hypothesis/Objectives – The primary aim of this study was to

Machine Learning Improves Risk Stratification in Myelodysplastic Neoplasms: An Analysis of the Spanish Group of Myelodysplastic Syndromes

HemaSphere, Volume 7, Issue 10, October 2023., 2023
Myelodysplastic neoplasms (MDS) are a heterogeneous group of hematological stem cell disorders characterized by dysplasia, cytopenias, and increased risk of acute leukemia. As prognosis differs widely between patients, and treatment options vary from observation to allogeneic stem cell transplantation, accurate and precise disease risk prognostication ...
