The aim of this study was to understand caregivers of individuals with dementia attitudes toward CBD oil. Thematic analysis was conducted with 67 posts (570 comments) about CBD oil selected from a Polish online support forum for caregivers. We identified caregivers' expectations, motivations, and practices of using CBD oil. Caregivers expected CBD to improve the behavior, cognition, communication, and daily activities of their loved ones. They motivated each other by sharing experiences about the positive effects of CBD oil and claimed to be administering CBD oil without medical advice, which led to dangerous practices such as an overnight withdrawal of all drugs or experimenting with CBD oil dosage. Caregivers perceive CBD oil as a safer and more effective treatment for those with dementia than the conventional methods. We recommend healthcare professionals inquire about possible CBD oil usage during follow-up visits and thoroughly explain what to expect from prescribed medications. [ABSTRACT FROM AUTHOR]

Cucumber (Cucumis sativus L.) germinates in an optimal temperature ranging from 24 to 28 °C. In order to develop cultivars with low temperature germination ability, knowledge regarding its genetic basis is needed. In our earlier study, we identified the accession PI 390953 as chilling tolerant and a good cold germinator. The objective of our present study was to compare cold germinability of cold tolerant breeding line B 5669 with PI 390953, and to measure the inheritance of this trait. At 13 °C, both tested cultigens (B 5669, PI 390953) showed the highest germinability and we found no significant differences between them regarding the rate of germination, days to germination (DTG), or germination index (GI). We also observed differences in the germination ability at 13 °C among seven hybrid populations of cucumber, derived from the cross between good cold germinator B 5669 (P1) and B 6115 (P2) lacking cold-germination ability. The fastest low temperature germination and the highest low temperature germination percentages were observed in B 5669 (P1) with germination of 78 and 100% on the 6th and 10th day of the test, respectively. In addition, the cultigen B 5669 exhibited the fastest germination, reaching on average of DTG = 5.7. B 6115 (P2) and BC1P2 proved unable to germinate at 13 °C even within 21 days. The seed germinability of F2 population fits a three-recessive gene model. Cucumber cultigens B 5669, PI 390953, and PI 246903 showed low temperature tolerance, but of them B 5669 may become the most desirable to breeders since it exhibits cold germinability combined with good fruit quality traits.

The aim of this study was to evaluate phenotypic variation of R0 androgenic plants obtained from four seed sources and donor plants by anther culture. Several morphological traits (leaf size, petiole length, leaf division, cortex colour) and the range of diversity were evaluated. There was large variation in all traits among the donor varieties. Especially leaf division and cortex colour differed significantly among the androgenic plants that came from different seed sources. The plants regenerated from four donor plants of variety 62 were significantly different in most traits except for leaf width and cortex colour. Evaluation of R1 plants will demonstrate whether the R0 variation observed is due to genetic variation or physiological differences from tissue culture.
