Background: It was previously shown that inactivation of gamma-synuclein which is a small soluble neuronal protein affects psycho-emotional status and cognitive abilities in knock-out mice.
Objective: Determine the role of gamma-synuclein inactivation on memory performance in aging animals.
Method: We used the passive avoidance test and acute amphetamine administration in aging gammasynuclein knock-out mice.
Results: As a result, we found moderate aging-unlinked deficit of dopaminergic neurotransmitter system of gamma-synuclein knock-out mice. At the same time, the evidence of progressive synaptic vesicle trafficking machinery impairment was obtained.
Conclusion: Therefore most likely these dysfunctions are associated with a reduction in the highefficient learning performance in tests that require intact working memory.

Background: Mental health disorders are one of the leading causes of illness globally. The importance of psychosocial skills acquired in early childhood, such as executive functions, inhibitory control, emotional regulation, and social problem-solving, in preventing mental disorders has been reported. Furthermore, mental health care delivery is evolving, and mobile technology is becoming the medium for assessment and intervention.

A substantial proportion of patients suffer from Post-COVID Syndrome (PCS) with fatigue and impairment of memory and concentration being the most important symptoms. We here set out to perform in-depth neuropsychological assessment of PCS patients referred to the Neurologic PCS clinic compared to patients without sequelae after COVID-19 (non-PCS) and healthy controls (HC) to decipher the most prevalent cognitive deficits. We included n = 60 PCS patients with neurologic symptoms, n = 15 non-PCS patients and n = 15 healthy controls.

Protein succinylation, a post-translational modification wherein a succinyl group (-CO-CH₂-CH₂-CO-) attaches to lysine residues, plays a critical regulatory role in cellular processes. Dysregulated succinylation has been implicated in the onset and progression of various diseases, including liver, cardiac, pulmonary, and neurological disorders. However, identifying succinylation sites through experimental methods is often labor-intensive, costly, and technically challenging.

Accurately predicting carbon prices is crucial for effective government decision-making and maintenance the stable operation of carbon markets. However, the instability and nonlinearity of carbon prices, driven by the complex interaction between economic, environmental, and political factors, often result in inaccurate predictions. To confront this challenge, this paper proposed a carbon price prediction model that integrates dual decomposition integration and error correction.
