A comparative study between Vitamin K1 and K2 on vascular calcification in hemodialysis patients: a randomized controlled trial
<p><span><span><strong>Background: </strong>Vascular calcification is a common complication of end stage renal disease patients, an important cause of cardiovascular disease and all-cause mortality. Vitamin K is essential for the activation of matrix Gla protein (MGP), a powerful inhibitor of tissue calcification. Different forms of vitamin K have been proposed to have a good impact on vascular calcification. However, clinical data are still limited on efficacy and safety of different forms of vitamin K.</span></span></p> <p><span><span><strong>Methods : </strong>A prospective, randomized, placebo-controlled study that included 120 eligible hemodialysis patients who were randomly assigned to either vitamin k1 group (10 mg phytomenadione thrice weekly) or vitamin k2 group (90 ug daily) or placebo group for 3 months. Serum MGP, calcium, phosphorus, their product, and intact parathyroid hormone (iPTH) levels, were all assessed at baseline and at the end of the study.</span></span></p> <p><span><span><b>Results:</b> There were significant increase in percentages of change in MGP levels in Vitamin k2 group (700%) compared to (78%) in Vitamin k1 & (40%) in placebo groups. No correlations observed between calcium, phosphorous and PTH and MGP levels at baseline or after treatment. None of the treatment group patients experienced any adverse effects.</span></span></p> <p><span><span><strong>Conclusion: </strong>Vitamin k supplementation was tolerable and effective with k2 form showing superiority over k1 in their impact on MGP levels among hemodialysis patients.</span></span></p> <p><span><span><b>ClinicalTrials.gov registration number:</b><b> NCT04477811</b><b>.</b></span></span></p> <p><span><span> </span></span></p>
Vascular plants of Ewe-Adakplame Relic Forest at Kétou in Benin, West Africa
<p>Covering 560.14 hectares in the south-east of Benin, the Ewe-Adakplame Relic Forest (EARF) is a micro-refugium<i> </i>that shows insular characteristics within the Dahomey Gap. It is probably one of the last remnants of tropical rain forest that would have survived the late Holocene dry period. Based on intensive field investigations through 25 plots (10 m × 50 m size) and matching of herbarium specimens, a checklist of 185 species of vascular plant belonging to 54 families and 142 genera is presented for this forest. In addition to the name for each taxon, we described the life form following Raunkiaer's definitions, chorology as well as threats to habitat. The Rubiaceae family was the richest (20 species) followed by the Fabaceae (15 species). Life forms showed the preponderance of phanerophytes (88%). The Chorological spectrum was dominated by Guineo-Congolean species (66%). Species richness estimated were 200.52 ± 9.2808 for <i>Bootstrap</i>; 217.62 ± 14.5972; 224.16 ± 15.3725 and 242.67 respectively for <i>Chao</i>, <i>Jacknife1</i> and <i>Jacknife2</i>. <i>Bootstrap</i> appears to be the estimation closer to the field records. In Benin, EARF is home for <i>Rinorea </i>species described as West African forest bio-indicators and single location for <i>Nesogordonia papaverifera</i>, <i>Mansonia altissima</i>, <i>Englerophytum oblanceolatum</i>, <i>Octolobus spectabilis</i>, <i>Vitex micrantha</i> and most of <i>Drypeteae</i> tribe species (<i>Drypetes aframensis, Drypetes afzelii, Drypetes gilgiana and Drypetes leonensis</i>) recorded in Benin. Our results provides baseline information for further in-depth analysis of vegetation history in Benin by raising the question on the past floristic connection of the Dahomey gap and community engagement in conservation.</p>
Native range estimates for red-listed vascular plants
<p>Besides being central for understanding both global biodiversity patterns and associated anthropogenic impacts, species range maps are currently only available for a small subset of global biodiversity. Here, we provide a set of assembled spatial data for terrestrial vascular plants listed at the global IUCN red list. The dataset consists of pre-defined native regions for 47,675 species, density of available native occurrence records for 30,906 species, and standardized, large-scale Maxent predictions for 27,208 species, highlighting environmentally suitable areas within species' native regions. The data was generated in an automated approach consisting of data scraping and filtering, variable selection, model calibration and model selection. Generated Maxent predictions were validated by comparing a subset to available expert-drawn range maps from IUCN (n = 4,257), as well as by qualitatively inspecting predictions for randomly selected species. We expect this data to serve as a substitute whenever expert-drawn species range maps are not available for conducting large-scale analyses on biodiversity patterns and associated anthropogenic impacts.</p>
