Estudo experimental de algumas substãncias antitóxicas

open access: yesRevista do Instituto Adolfo Lutz, 1943
Os autores fazem um estudo comparativo da ação de várias substâncias antitóxicas, verificando que a única que protegeu eficientemente os animais contra a intoxicação pelo tetracloreto de carbono, foi o xantinato de sódio, na dose de 100 mgrs. por 100 grs. de peso. Ao lado disso, verificaram, também, que o xantinato de sódio, quando empregado nesta dose,

Analysis of the Matrix Metalloproteinases Family Profile in Gastric Cancer Suggests Key Matrix Metalloproteinases for Tumor Development and Their Clinical Impact

open access: yesMolecular Carcinogenesis, EarlyView.
ABSTRACT Gastric cancer (GC) is the fifth most common type worldwide, representing a public health problem. Among the genes related to this tumorigenesis, the family of matrix metalloproteinases (MMPs), essential regulators of the extracellular matrix (ECM), stand out for their involvement in the development and progression of GC.

Cognitive Dysfunction Is Associated With an Underestimation of Respiratory Function in ALS

open access: yesMuscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims The association between low forced vital capacity (FVC) and cognitive impairment in ALS is ambiguous; it could be due to respiratory dysfunction and/or poor effort from cognitive deficits. We used the objective, non‐volitional phrenic nerve motor response amplitude (PAmp) to clarify how cognitive status affects the ...

Impact of a low‐carbohydrate diet on cardiometabolic parameters in individuals with and without diabetes: An 8‐year longitudinal study within the ELSA‐Brasil cohort

open access: yesNutrition in Clinical Practice, EarlyView.
Abstract Background Low‐carbohydrate diets (LCDs) are widely adopted for metabolic management, but their long‐term cardiometabolic effects in diverse populations remain unclear. We aimed to evaluate the association between self‐selected moderate LCD adherence and cardiometabolic parameters in individuals with and without diabetes.

Floral trait similarity at the community‐level increases reproductive success suggesting facilitation through pollinator sharing

open access: yesOikos, EarlyView.
The ability of plants to attract pollinators is context‐dependent, influenced by floral traits, abundance, and resources from the plant community. Indirect interactions through shared pollinators, from competition to facilitation, may lead to varied reproductive outputs in plants, and the mechanisms behind these interactions remain to be fully ...
