Article Synopsis
  • There are five subtypes of somatostatin receptors (SST1-5) that play roles in various tumors, with SST2 and SST5 being the most relevant for diagnosis and treatment.
  • The article reviews the biological features of SST, emphasizing the immunohistochemical evaluation of SST2 and SST5 in growth hormone-secreting pituitary tumors as predictors of treatment response to somatostatin receptor ligands (SRL).

Spinal cord injury (SCI) is one of the most serious conditions of the central nervous system, causing motor and sensory deficits that lead to a significant impairment in the quality of life. Previous studies have indicated that inosine can promote regeneration after SCI. Here we investigated the effects of inosine on the behavioral and morphological recovery after a compressive injury.

Background Aims: Cut-points for non-invasive tests (NITs) for risk stratification in metabolic dysfunction-associated steatotic liver disease (MASLD) were derived from predominantly non-Hispanic populations. It is unknown if these cut-points perform adequately in Hispanic individuals. We assessed the performance characteristics of current NIT cut-points among Hispanic patients and determined whether they could be further optimized.

Pituitary gigantism due to a novel germline splice-site variant.

Endocr Oncol

January 2024

Neuroendocrinology Research Center, Endocrinology Section, Medical School and Hospital Universitário Clementino Fraga Filho, Universidade Federal do Rio de Janeiro, Brazil.

Article Synopsis
  • Pituitary gigantism is a rare condition in kids caused by excessive growth hormone, often linked to genetic factors, particularly mutations in the aryl hydrocarbon receptor-interacting protein gene.
  • A case study of an 11-year-old boy highlighted symptoms like progressive vision loss, rapid growth, and weight gain, with tests confirming high levels of growth hormone and indicating a tumor causing these issues.
  • Despite two surgeries and medications, including Pasireotide and cabergoline, his condition showed only partial improvement, and researchers identified a new likely pathogenic genetic variant contributing to his gigantism.

Laboratório de Estudos em Imunologia, Departamento de Análises Clínicas e Toxicológicas, Faculdade de Farmácia, Universidade Federal do Rio de Janeiro, Avenida Carlos Chagas Filho 373, Bloco A, 2° Andar - sala 05, Cidade Universitária, Ilha do Fundão, 21941-902 Rio de Janeiro, Brazil.

Antimicrobial resistance is an increasing worldwide public health burden that threatens to make existent antimicrobials obsolete. An important mechanism of antimicrobial resistance is the overexpression of efflux pumps, which reduce the intracellular concentration of antimicrobials. TolC is the outer membrane protein of an efflux pump that has gained attention as a therapeutic target.

 To analyze the mechanical properties of the patellar (PT) and semitendinosus (ST) tendons from fresh-frozen human cadavers from a tissue bank using supersonic shear-wave imaging (SSI) elastography and tensile tests.  We tested seven PT and five ST samples on a traction machine and performed their simultaneous assessment through SSI. The measurements enabled the comparison of the mechanical behavior of the tendons using the stress x strain curve and shear modulus (μ) at rest.

Electronic address:

Objective: The biological behavior of Cerebral Cavernous Malformation (CCM) is still controversial, lacking a clear-cut signature for a mechanistic explanation of lesion aggressiveness. In this study, we evaluated the predictive capacity of genetic variants concerning the aggressive behavior of CCM and their implications in biological processes.

Methods: We genotyped the variants in VDR, VDR, VDR, PTPN2 and FCGR2A genes using TaqMan Genotyping Assays in a cohort study with 103 patients, 42 of whom had close follow-up visits for 4 years, focusing on 2 main aspects of the disease: (1) symptomatic events, which included both intracranial bleeding or epilepsy, and (2) the onset of symptoms.
