Smoking abstinence responses were characterized in 96 female smokers. Participants completed subjective state measures twice per week for 5 weeks and were then randomly assigned to a group required to abstain for 31 days or a control group that continued to smoke. Financial incentives for biochemically verified abstinence resulted in an 81% completion rate. Abstinence-related increases in depression, tension, anger, irritability, and appetite showed little tendency to return to prequit levels and remained significantly elevated above smoke-group levels. In contrast to psychological components of anxiety, physical components decreased to smoke group levels by the 2nd week of abstinence. Trait depression and neuroticism predicted larger increased abstinence-associated negative affect. The Big Five personality dimensions predicted variance not associated with depressive traits.

Background: Increased emotional reactivity to stress, emotional dysregulation and sleep disturbances are interdependent trans-diagnostic processes that are present in internalising disorders such as depression and anxiety disorders. This study investigated which objective and subjective parameters of stress reactivity, sleep and emotional processing would predict symptoms of anxiety and depression in adolescents and young adults.
Methods: Participants were adolescents and young adults between the ages of 14 to 21 (N = 106, 25[24 %] male, M age = 17.
Emerging roles for tubulin PTMs in neuronal function and neurodegenerative disease.
Curr Opin Neurobiol

Department of Pathology & Cell Biology, Columbia University Irving Medical Center, 10032, New York, NY, USA. Electronic address:
Neurons are equipped with microtubules of different stability with stable and dynamic domains often coexisting on the same microtubule. While dynamic microtubules undergo random transitions between disassembly and assembly, stable ones persist long enough to serve as platforms for tubulin-modifying enzymes (known as writers) that attach molecular components to the α- or β-tubulin subunits. The combination of these posttranslational modifications (PTMs) results in a "tubulin code," dictating the behavior of selected proteins (known as readers), some of which were shown to be crucial for neuronal function.

Department of Child and Family Studies, University of South Florida, Tampa, FL 33620, USA.
Background/objectives: Sleep disturbances are prevalent among pediatric cancer survivors (PCSs) and their caregivers, often leading to poorer dietary choices and reduced physical activity. Additionally, the sleep quality and health behaviors of parents and children can affect each other. This study examined bi-directional associations between PCSs and their parents' sleep quality and health-related behaviors.

As adults spend about 30% of each day asleep, having a sleep disorder can negatively affect their functioning. The study objective was to determine the factors that influence sleep quality among patients and healthcare providers in the primary healthcare setting. This study included respondents of both sexes aged 18-90 years, comprising outpatients and the healthcare providers working in the General Medicine Service at the "Liman" Department of the "Novi Sad" Health Center in Novi Sad, Republic of Serbia.
