Posttraumatic Stress Symptom Severity and Marijuana Use Coping Motives: A Test of the Mediating Role of Non-judgmental Acceptance Within a Trauma-exposed Community Sample

We examined the role of non-judgmental acceptance in the relation between posttraumatic stress symptom severity and marijuana use coping motives. These relations were examined among 97 (46 women) adults (M age = 21.57 years, SD = 6.32) who met DSM-IV-defined PTSD Criterion A for at least one traumatic event exposure and reported using marijuana in the past 30 days. Consistent with expectation, greater levels of posttraumatic stress symptom severity were associated with greater levels of coping-oriented marijuana use motives, as well as lower levels of non-judgmental acceptance. Furthermore, non-judgmental acceptance was inversely associated with coping-oriented marijuana use motives. Finally, non-judgmental acceptance was found to partially mediate the association between posttraumatic stress symptom severity and marijuana use coping motives. Results are discussed in terms of better understanding the role of non-judgmental acceptance in coping-oriented marijuana use among trauma-exposed populations

The complete mitochondrial and plastid genomes of Corallina chilensis (Corallinaceae, Rhodophyta) from Tomales Bay, California, USA

Genomic analysis of the marine alga Corallina chilensis from Tomales Bay, California, USA, resulted in the assembly of its complete mitogenome (GenBank accession number MK598844) and plastid genome (GenBank MK598845). The mitogenome is 25,895 bp in length and contains 50 genes. The plastid genome is 178,350 bp and contains 233 genes. The organellar genomes share a high-level of gene synteny to other Corallinales. Comparison of rbcL and cox1 gene sequences of C. chilensis from Tomales Bay reveals it is identical to three specimens from British Columbia, Canada and very similar to a specimen of C. chilensis from southern California. These genetic data confirm that C. chilensis is distributed in Pacific North America
