Morphological and histopathological description of Calyptospora sp. parasitism in Cichla monoculus Spix, 1929 (Osteichthyes, Cichlidae) from the lake region of Pracuúba-Amapá, Brazil.

The tucunaré (Cichla sp.) is an Amazonian fish that is heavily commercialized in the state of Amapá, and it can be infected by a variety of parasites, including coccidia of the genus Calyptospora, which are identified at the genus level by analyzing the structures that comprise its morphology. This study aimed to describe the morphology and histopathology of Calyptospora sp.

Is Tumor Growth Influenced by the Bone Remodeling Process?

In this study, we develop a comprehensive model to investigate the intricate relationship between the bone remodeling process, tumor growth, and bone diseases such as multiple myeloma. By analyzing different scenarios within the Basic Multicellular Unit, we uncover the dynamic interplay between remodeling and tumor progression. The model developed developed in the paper are based on the well accepted Komarova's and Ayati's models for the bone remodeling process, then these models were modified to include the effects of the tumor growth.

Role of the Laryngeal Adductor Reflex in the Prevention of Thermal Injury to the Recurrent Laryngeal Nerve in Thyroid Surgery: A Case Report.

Background: Intraoperative neuromonitoring (IONM) of the recurrent laryngeal nerve (RLN) aims to detect and prevent iatrogenic damage during thyroid surgery. Mechanisms of injury include traction, heat damage, and nerve transection. Continuous IONM (C-IONM) techniques detect impending damage due to traction and heat related when they are still reversible.

Comparative analysis of gut microbiota in hormone-sensitive and castration-resistant prostate cancer in Japanese men.

Gut microbiota plays a crucial role in the development and progression of prostate cancer, with previous studies indicating that certain bacterial taxa are more abundant in castration-resistant prostate cancer (CRPC) compared to hormone-sensitive prostate cancer (HSPC). Notably, the composition of gut microbiota can vary significantly by geographic region, and Japanese individuals have a distinct microbial profile. However, research exploring these differences within Japanese populations remains limited.
