Effectiveness of cognitive-behavioral therapy on mental health, life expectancy, and happiness in patients receiving methadone maintenance treatment.

Background: Nowadays, the issue of substance abuse is one of the major problems facing most countries in the world. The present study aimed to evaluate the effectiveness of cognitive-behavioral therapy (CBT) on mental health, life expectancy, and happiness in patients receiving methadone maintenance treatment (MMT).

Materials And Methods: The present study was performed from February 2021 to January 2022.

Study of the effects of cognitive behavioral therapy versus dialectical behavior therapy on executive function and reduction of symptoms in generalized anxiety disorder.

Introduction: The effects of dialectical behavior therapy on generalized anxiety disorder have not been examined to date, whereas cognitive behavioral therapy is a well-known psychotherapy for generalized anxiety disorder.

Objectives: This study investigated the effects of cognitive behavioral therapy versus dialectical behavior therapy on executive function and reduction of symptoms in generalized anxiety disorder.

Method: In the present study, 72 generalized anxiety disorder patients were randomly assigned to one of two groups: dialectical behavior therapy or cognitive behavioral therapy.

Computational prediction of the spin-polarized semiconductor equiatomic quaternary Heusler compound MnVZrP as a spin-filter.

In this work, a new equiatomic quaternary Heusler (EQH) compound, MnVZrP, is predicted using first principles calculations. Simulations show the good stability of the material, suggesting experimental realization. Results show that MnVZrP is a magnetic semiconductor material, exhibiting semiconductor characteristics in both spin channels, however, with strong spin-polarization.

Comparing Perceived Social Support and Perceived Stress in Healthy Pregnant Women and Pregnant Women with Preeclampsia.

Background: Preeclampsia is a prevalent side effect of pregnancy. Different studies have reported different results about the relationship between mental stress and blood pressure disorders. In addition, social support is highly important to help women who experience risky pregnancy in adapting to the stressors they experience.

Determination of Sn(II) and Sn(IV) after mixed micelle-mediated cloud point extraction using alpha-polyoxometalate as a complexing agent by flame atomic absorption spectrometry.

The cloud point extraction behavior of Sn(II) and Sn(IV) using alpha-polyoxometalate and mixed surfactants solution was investigated. The mixture of a nonionic surfactant (Triton X-100) and a cationic surfactant (CTAB) was utilized as a suitable micellar medium for preconcentration and extraction of tin complexes. Sn(II) in the presence of Sn(IV) was extracted with alpha-polyoxometalate, 0.
