Background and aims

This study examined the lived experience of individuals who underwent ibogaine treatment for an opioid use disorder.

Methods

Semi-structured interview questions probed for potential changes in predetermined categories derived from a literature review. Participants’ experiences with ibogaine were analyzed for commonalities and emergent themes.

Results

Categories that emerged revealed themes about subjective neurological and physical effects, auditory and visual phenomena, impact on withdrawal and craving, and shifts in outlook on self and life.

Conclusion

Ibogaine treatment provides a subjectively powerful physiological, emotional, and psychological experience, attenuates opioid withdrawal, and results in a more optimistic outlook on self and life.

To clarify the effects of dihydrotestosterone (DHT)-induced polycystic ovary syndrome (PCOS) on arteriolar biomechanics in a rat model and the possible modulatory role of vitamin D3.Methods and Results The PCOS model was induced in female Wistar rats by ten-weeks DHT treatment. Arteriolar biomechanics was tested in arterioles by pressure arteriography in control as well as DHT- and DHT with vitamin D3-treated animals in contracted and passive conditions. Increased wall stress and distensibility as well as increased vascular lumen were detected after DHT treatment. Concomitant vitamin D3 treatment lowered the mechanical load of the arterioles and restored the vascular diameter.Conclusion The hyperandrogenic state resulted in more rigid, less flexible arteriolar walls with increased vascular lumen compared with controls. DHT treatment caused eutrophic remodelling of gracilis arteriole. These prehypertensive alterations caused by chronic DHT treatment were mostly reversed by concomitant vitamin D3 administration.

The combined effect of surgical treatment and consumption of so-called “CoD™ tea” (containing Uncaria guianensis, U. tomentosa and Tabebuia avellanedae) on expression of c-myc, Ha-ras, Bcl-2, Ki-ras and p53 key onco/suppressor genes, the carbohydrate antigen (CA19-9) and carcino-embryonic antigen (CEA) tumour markers in blood samples of patients with colorectal cancer (CRC) were investigated. Expression of genes followed the effect of the surgical treatment combined with neoadjuvant chemotherapeutic treatment; this may predict the outcome of carcinoma. Moreover their expressions might show possible additional effect of supportive therapy, e.g. CoD™ consumption. The antioxidant capacity of blood was also examined. Blood samples were taken at the day of, and one week, 3, 6 and 12 months after the surgical treatment. During that period patients got 0.25 l standard portion of CoD™ tea three times a day. The surgical treatment and neoadjuvant therapy were able to suppress the expression of c-myc, Ha-ras, Bcl-2, Ki-ras, p53 genes up to the twelfth month. Moreover, CoD™ tea together with conventional treatment caused a strong decrease in the expression of c-myc and Ha-ras oncogenes in comparison to the non-consumer control.

Abstract  

Pituitary adenylate cyclase activating polypeptide (PACAP) is a widely distributed neuropeptide that has two molecular forms with 38 and 27 amino acid residues. The aim of the present study was to develop a new, highly specific PACAP-27 assay to investigate the quantitative distribution of PACAP-27 in the central nervous system of various vertebrate species applying the same technical and experimental conditions. Our results show that the antiserum used turned to be PACAP-27 specific. The average ID50 value was 51.5±3.6 fmol/ml and the detection limit was 2 fmol/ml. PACAP-27 immunoreactivity was present in the examined brain areas, with highest concentration in the rat diencephalon and telencephalon. Swine and pigeon brain also contained significant amount of PACAP-27. Our results confirm the previously described data showing that PACAP-38 is the dominant form of PACAP in vertebrates, since PACAP-38 levels exceeded those of PACAP-27 in all examined brain areas. Furthermore, our study describes for the first time, the comparative quantitative distribution of PACAP-27 and-38 in the swine and pigeon brain.

Gas sensing properties of different carbon nanotube (mostly multiwall, MWCNT) mats, based on electrical resistance measurement were investigated in a simple arrangement and found that the sensitivity for different gases or vapors highly depends on the pre-treatment and functionalization of nanotubes. The selectivity of the sensing was demonstrated by building a vapor recognition system based on an array of multitube sensors made of differently functionalized MWCNTs.

In the present paper we report original thousand-seed weight data for the flora of the Pannonian Basin. Our goal was to demonstrate the usefulness of seed weight databases by analysing seed weight data in relation to social behaviour types and life forms. We specifically asked the following questions: (i) how the seed weights are related to social behaviour type categories; (ii) how the life form of the species influences seed weight differences between respective social behaviour types? Own weight measurements are provided for 1,405 taxa; and for 187 taxa we published seed weight data for the first time: these were mostly endemics, orchids and/or species with Pontic, Caspian or continental distribution. Several taxonomic or functional groups are underrepresented in our database, like aquatic plants, rare arable weeds and sub-Mediterranean species. Problematic taxa, some difficult-to-harvest species or species with low seed production and cultivated adventives are also underrepresented. We found that the plant strategies expressed by social behaviour types were significantly different in terms of seed weights. The lowest seed weight scores were found for natural pioneers, whereas the highest ones were found for adventives and introduced cultivated plants. Short-lived herbaceous species had significantly higher seed weight scores than herbaceous perennials. No significant differences were found between specialists and generalists within the stress tolerant group. We found that short-lived graminoids possess heavier seeds than perennial graminoids, perennial and annual forbs. Naturalness scores were negatively correlated with seed weights. Our findings showed that seed collections and databases are not only for storing plant material and seed weight data, but can be effectively used for understanding ecological trends and testing plant trait-based hypotheses. Even the identified gaps underline the necessity of further seed collection and measurements.
