Exposure to an acute stress impaired the metabolic plasticity of resilient rats by enhancing fatty acid β-oxidation in the ventral hippocampus.

The concept of resilience has changed over time and nowadays it refers to the positive adaptation to life adversities, rather than to the absence of a pathological response normally occurring in susceptible people. Based on our previous data showing that the exposure to the chronic mild stress (CMS) paradigm differently affected bioenergetics in the ventral hippocampus of vulnerable and resilient animals, here we investigated whether resilience is a stable trait or if the energetic strategy set in motion to sustain resilience unveils a vulnerability feature in a more dynamic situation. To this aim, vulnerable and resilient rats after 6 weeks of CMS were subjected to a further acute, unfamiliar restraint stress (ARS) and metabolomic studies were conducted in the ventral hippocampus.

Electrodiagnostic subtyping in Guillain-Barré syndrome patients in the International Guillain-Barré Outcome Study.

Background And Purpose: Various electrodiagnostic criteria have been developed in Guillain-Barré syndrome (GBS). Their performance in a broad representation of GBS patients has not been evaluated. Motor conduction data from the International GBS Outcome Study (IGOS) cohort were used to compare two widely used criterion sets and relate these to diagnostic amyotrophic lateral sclerosis criteria.

An In Vitro Study on the Role of Cellulases and Xylanases of in Dairy Cattle Nutrition.

The administration of to dairy cows exerts beneficial effects on dry matter intake, lactation performance, and milk composition, but the rationale behind their efficacy is still poorly understood. In this work, we sought to establish whether cellulases and xylanases, among the enzymes secreted by , are involved in the positive effect exerted by on ruminal performance. We took advantage of two isogenic strains, only differing in the secretion levels of those two enzymes.

Condensed tannins fed to dairy goats: Effects on digestibility, milk production, blood parameters, methane emission, and energy and nitrogen balances.

Condensed tannins (CT) are plant polyphenols that can affect feed digestibility and are potentially able to reduce enteric CH emissions in ruminants. In this in vivo trial with 8 lactating goats, we investigated the effects of 4 levels of inclusion of a commercial CT extract from quebracho (0%, 2%, 4%, and 6% on dry matter basis; CON, Q2, Q4, and Q6, respectively). The experimental design was a repeated 4 × 4 Latin square with 28-d periods (24 d of diet adaptation and 4 d of sample collection) using metabolic cages and 4 open-circuit respiration chambers.

Predictors of respiratory failure in Guillain-Barré syndrome: a 22 year cohort study from a single Italian centre.

Background And Purpose: The study aimed to identify predictors of respiratory failure leading to mechanical ventilation (MV) and tracheostomy in Guillain-Barré syndrome (GBS).

Methods: Two hundred and thirty adult cases admitted to the Neurology Unit of Modena, Italy, between January 2000 and December 2021 were studied. A cut-off of MV starting within 8 weeks from onset of weakness was used.
