Theoretical calculations of nonlinear optical responses for interpreting nonconjugated molecular systems to affect non-optimal properties.

Understanding the intricacies of polymorphic origins in nonconjugated crystal systems is crucial for optimizing their properties. This study focuses on the crystal growth, characterization, and nonlinear optical (NLO) responses of a system analyzed using single crystal X-ray analysis, revealing a monoclinic geometry. Hirschfeld surface analysis emphasized the significance of intermolecular interactions in driving polymorph development, shedding light on the structural nuances influencing the material's properties.

Are we closer to achieving precision medicine for migraine treatment? A narrative review.

Background: The term 'precision medicine' encompasses strategies to optimize diagnosis and outcome prediction and to tailor treatment for individual patients, in consideration of their unique characteristics. The greater availability of multifaceted datasets and strategies to model such data have made precision medicine increasingly possible in recent years. Precision medicine is especially needed in the migraine field since the response to migraine treatments is not universal amongst all individuals with migraine.

Midwakh smoking as an emerging risky behavior: insight from Qatar 2022.

Background: Alternative tobacco products like midwakh are gaining popularity as potential substitutes for traditional cigarettes despite a misconception among smokers that they may be less harmful.

Objectives: To determine the prevalence, knowledge, beliefs, and predictors of midwakh smoking among adult smokers in Qatar during 2022.

Method: An analytic cross-sectional study was conducted from January 2022 to July 2022.
