Objective: Epidemiological studies suggest that long-chain polyunsaturated fatty acids (LC-PUFAs) may be suitable as endophenotypes for ADHD. To be appropriated vulnerability traits, endophenotypes should be altered in unaffected relatives of index cases. Serum profiles of LC-PUFAs in unaffected relatives of ADHD patients remain understudied. The main objective of this study was to compare serum LC-PUFAs in ADHD patients, unaffected relatives of index cases, and general-population unaffected participants.
Method: LC-PUFA profiles of 72 participants (27 ADHD patients, 27 unaffected relatives, and 18 general-population participants) were obtained by gas chromatography-mass spectrometry (GC-MS). Groups were compared by parametrical statistics.
Results: Unaffected females from the general population presented lower Docosapentaenoic acid (DPA; p = .0012) and a-linolenic acid (ALA; p = .0091) levels compared with ADHD females and unaffected relatives. In addition, docosahexaenoic acid (DHA)/ALA and DHA/DPA ratios, addressing desaturase activity, were significantly lower in ADHD patients and unaffected relatives of ADHD patients in the female-subgroup (p = .022 and .04, respectively).
Conclusion: DHA/ALA, DHA/DPA, serum DPA, and serum ALA may be suitable as endophenotypes for ADHD women.

Background And Aims: This study aimed to compare neurological soft signs (NSSs) in type 1 bipolar disorder (BD), bipolar spectrum (BS) patients, and their unaffected first-degree relatives.
Methods: This descriptive cross-sectional study involved participants referred to the Psychiatric Department of Imam Hossein Hospital. Five groups ( = 25): patients with type 1 BD, patients with BS, unaffected first-degree relatives of the two groups, and a control group were evaluated using the Neurological Evaluation Scale (NES).

In this paper we contribute to a long history of research studying interactions between energy systems, international energy trade, and macroeconomic activity. We develop and employ methods to quantify transmission pathways for energy markets to affect the macroeconomy and CO emissions. We track the long-term consequences of a hypothetical permanent disruption to global energy markets, cession of Russian fossil fuel exports, for energy markets, regional and global economic activity (gross domestic product [GDP]), labor and capital markets, and CO emissions against two dramatically different reference scenarios.

Implanted biomaterials release inorganic ions that trigger inflammatory responses, which recruit immune cells whose biochemical signals affect bone tissue regeneration. In this study, we evaluated how mouse macrophages (RAW264, RAW) and mesenchymal stem cells (KUSA-A1, MSCs) respond to seven types of ions (silicon, calcium, magnesium, zinc, strontium, copper, and cobalt) that reportedly stimulate cells related to bone formation. The collagen synthesis, alkaline phosphatase activity, and osteocalcin production of the MSCs varied by ion dose and type after culture in the secretome of RAW cells.

An athlete's performance and musculoskeletal health hinges on their ability to adapt their movements to varying environmental constraints. However, research has yet to offer a thorough understanding of whether coordination variability is altered in response to different synthetic and natural turf surfaces. The purpose of this study was to investigate lower extremity coordination variability during hopping and running on four turf surfaces-three synthetic and one natural.

The compounds targeting the bromo and extra terminal domain proteins (BET), such as the JQ1, present potent anti-cancer activity in preclinical models, however, the application of JQ1 at the clinical level is limited by its short half-life, rapid clearance, and non-selective inhibition of BET family proteins, leading to off-target effects and resistance. To address these challenges, the optimization of JQ1 delivery has been accomplished through polylactide (PLA) nanoparticles. PLA derivatives with varying molecular weights were synthesized via ring-opening polymerization using a zinc-based initiator and characterized using thermogravimetric analysis, differential scanning calorimetry, and infrared spectroscopy.
