The concentration of tumor markers in body fluids can be used for diagnosis and prognosis of patients. This study aimed to investigate the performance of tumor markers cytokeratin 19 fragment (CYFRA 21-1), cancer-associa...

The Bruton nonreceptor protein-tyrosine kinase (BTK) plays a central role in B cell antigen receptor signaling. Following B cell receptor activation, the Src protein kinase Lyn and the spleen protein kinase (Syk) activat...

Objective: Brain metastases (BMs) are the most common intracranial tumors in adults and represent a major cause of morbidity and mortality in patients with systemic malignancies. This study aimed to evaluate the clinical...

Abstract Background Lymphoma has been implicated as a possible cause of proteinuria in dogs. However, information about the potential importance of proteinuria in dogs with lymphoma is limited. Hypothesis To determine if...

Abstract Background Although the importance of early diagnosis of malignant tumors is a major concern, an easily accessible in‐house method has not been established. Objectives To investigate the most optimal model by ...

Objetivos: os autores modificaram a espátula de Ayre original visando otimizar a colheita endocervical. O estudo verificou se a capacidade da espátula modificada em colher células da endocérvice é semelhante à obti...

Tuberculosis is still a major health problem especially among immunocompromised hosts. Another problem is making diagnosis due to the unexpected presentation and localization of disease. Extrapulmonary disease may clinic...

Abstract Background Diffuse astrocytoma (DA) is the most common intraparenchymal brain tumor, primarily occurring in the frontal and temporal lobes. However, its occurrence in the lateral ventricles is rare. Case present...

Multiple Primary Cancers (MPCs), especially synchronous combined hepatocellular-cholangiocarcinoma (cHCC-CCA) complicated with gallbladder adenocarcinoma, are extremely rare clinically. This case report discusses a 73-ye...

Liver cirrhosis is characterized by an excessive accumulation of extracellular matrix components, including hyaluronan (HA). In addition, cirrhosis is considered a pre-neoplastic disease for hepatocellular carcinoma (HCC...

Non-lethal biological techniques such as blood biomarkers have gained attention due to their value as early signals of anthropic effects of contamination representing significant tools to evaluate ecosystems health. We e...

Multiple primary malignancies (MPMs) are increasingly recognized, yet the impact of immune checkpoint inhibitors (ICIs) on the evolution of metachronous tumors remains poorly understood. Here, we report a rare case of me...

ABSTRACT A 10-year-old male mixed-breed dog was admitted for recurrent signs of urinary tract infection (UTI). Urinary bladder ultrasonography revealed decreased thickness of its wall with floating hyperopic particles wi...

With the purpose of shedding light on some doubts in veterinary oncology, the present article intends to compare the results of histopathological and immunohistochemical examinations of unspecific round cell neoplasia, t...

Gestational trophoblastic disease (GTD) includes both neoplastic and nonneoplastic disorders arising from placental trophoblastic tissue. Among tumor-like conditions, exaggerated placental site reaction (EPSR) is a rare ...

Inorganic materials contain remarkable properties for drug delivery, such as a large surface area and nanoporous structure. Among these materials, CaCO3 microparticles (CMPs) exhibit a high encapsulation efficiency and s...

Abstract Obstructive or nonobstructive hypertensive hydrocephalus is reported in choroid plexus tumors. Choroid plexus tumors typically present as T2‐weighted hyperintense intraventricular masses with occasional cerebr...

Abstract Background Lymphocytosis is relatively common in cats, but few studies describe lymphocyte populations or the clinical course associated with different immunophenotypic expansions. Hypothesis/Objectives We hypot...

Background: Paclitaxel, a potent anti-neoplastic agent, finds application in treating various malignancies like breast, ovarian, lung, and pancreatic cancers. However, paclitaxel's hydrophobicity renders it poorly solubl...
