ETHNOPHARMACOLOGICAL RELEVANCE Flora of the Mexican region is represented by approximately 30,000 vascular plant species, many of which are used as traditional medicines based on knowledge compiled and refined since ancient times (e.g. Cruz-Badiano and Florentino Codexes). The traditional use of plants as medicines, including the treatment of infectious diseases such as diarrhoea, is generally practiced in communities that are geographically isolated or in human settlements where health services are scarce. AIM OF THE STUDY The aim of this review is to evaluate current research advances in the ethnopharmacology and phytochemistry of Mexican medicinal plants exhibiting antiprotozoal activity, used to treat diarrhoea, and to identify the gaps in this research area for future studies. METHODS The literature study and compilation of information relied on books and scientific journals from leading electronic databases including Scopus, Springer, SciFinder, ISI Web of Science, PubMed, and Google Scholar; the topicsants with antiprotozoal activity has yielded relevant findings whose results provide evidence-based support for the use of these plants in the traditional medicine of Mexico to treat diarrhoea. Toxicological and clinical trials of standardized extracts and bioactive compounds are proposed as priority future works in this research area. In addition, in vivo assays are required, of more extracts and/or pure compounds. The optimization of the pharmacological properties of the bioactive specialized metabolites through semisynthetic derivatives and computational methods could aid in developing new antiprotozoal phytomedicines and novel drugs for the treatment of these types of infections. Furthermore, elucidation of the mechanism of action of these bioactive compounds through pharmacological and molecular studies are also necessary. The Vitamin D External Quality Assessment Scheme (DEQAS) distributes serum samples globally, on a quarterly basis, to assess participants' performance of specific methods for 25-hydroxyvitamin D (25OHD) and 1,25-dihydroxyvitamin D (1,25-(OH)2D). DEQAS occasionally circulates samples containing high levels of substances found in certain clinical situations e.g. 25-OH-D2, 24,25-(OH)2D3, hypertriglyceridemia. The increased availability and use of health supplements containing biotin has led to case reports of assay interference in methods utilizing a biotin-streptavidin detection system. In October 2018, DEQAS included a serum sample (545) containing exogenous biotin (concentration =586 μg/L) which was analyzed by a total of 683 laboratories using 35 different methods. The same serum sample (544) without exogenous biotin was also included in the 5-sample set. All methods (760 laboratories) performed satisfactorily on sample 544 giving an All-Laboratory Trimmed Mean = 50.2 ± 6.5 nmol/L (±SD, CV = 12.9%). The targto report sample 545 data from 77 laboratories is due solely to those running Roche Total 25OHD or Roche Vitamin D Total II assays. Given the prevalence of the adversely affected assays (25% of DEQAS users) and the high volume of 25OHD testing, clinicians using these assays should, where possible, only measure 25OHD when patients are off biotin. Adequate nutrition is essential for maintaining good oral health. Minerals such as magnesium, calcium, and phosphorus found in the diet constitute the main structural components of the tooth. Their inadequacy leads to absorption impairment, increased bleeding tendency, bone resorption, looseness, and premature tooth loss. Inadequacy of those essential minerals is associated with delayed tooth eruption and with enamel or dentin hypoplasia. Taking calcium without magnesium results in soft dental enamel, which cannot resist the acids causing tooth decay. In addition to magnesium, calcium, and phosphorus, adequate vitamin D is needed to maintain optimal oral health. Vitamin D exerts anti-inflammatory effects and helps in calcium absorption and bone remodeling. Moreover, adequate vitamin D status could reduce formation of dental caries by delaying its onset and progression. Here we summarize the oral manifestations of vitamin D and magnesium inadequacy. Combined liver-kidney transplantation is a life-saving procedure for patients with end-stage liver disease and underlying chronic kidney disease, or prolonged acute kidney injury. Due to physiologic changes secondary to portal hypertension in patients with end-stage liver disease, kidney injury is common, and combined liver-kidney transplantation accounts for 10% of all the liver transplants performed in the United States. Recently implemented policy in the United States standardizes the medical criteria for eligibility, and introduces a 'safety net' for those who are transplanted with a liver graft alone, in order to be able to receive a kidney graft later. Increasing number of combined liver-kidney transplants provides a large cohort of patients to be studied in detail for identification of factors (both donor and recipient-related) associated with better outcomes. Data regarding the safety and efficacy of delaying the kidney transplant part of the combined liver-kidney transplantation, and the immunologic benefits of the multi-organ transplantations including the liver are emerging. Here, we review the most recent analyses, and provide our opinion regarding the best practices in combined liver-kidney transplantation based on the evidence. OBJECTIVES Although fractures occur in various bones, including long, short, and flat bones, fracture repair investigations focus on the diaphysis of the long bone. The cell composition, osteogenic capacity, and bone matrix differ among osteogenesis patterns. However, the differences in the bone repair process have not been studied. Here, we compared the bone repair processes in the parietal bone and scapula of adolescent mice. METHODS Bone apertures were created in the parietal bone and scapula. Samples were collected at indicated times after surgery, and the repair process was analyzed using micro-computed tomography, histological, immunohistochemical, and mRNA expression analyses. RESULTS In both repair processes, cartilage formation was not detected on the periosteum side. click here The parietal bone aperture was gradually filled with newly formed bone produced from the edge of the aperture by day 14 but was not completely repaired even by day 49. In the scapula, a bony callus was detected on the periosteum at day 7, and the aperture was bridged by day 14. Subsequently, the bony callus was remodeled to the original bone architecture. Alkaline phosphatase activity and osteocalcin synthesis occurred earlier in the repair region of the scapular periosteum, compared with that in the parietal periosteum. The mRNA expression of osteogenic markers in the periosteum was markedly upregulated in the scapula versus the parietal bone. CONCLUSION Our study findings clarify the differences between parietal bone and scapula repair and suggest that the bone repair process differs among ossification patterns. Central venous catheters (CVCs) are extensively used in patients undergoing allogeneic hematopoietic cell transplantation (HCT). In these patients CVC are placed routinely either via the internal jugular vein (IJV) or the subclavian vein (SCV). Purpose of this study was to systematically analyze complications of CVC at different insertion sites in HCT recipients. In this retrospective analysis, all consecutive patients (n = 56) who received a CVC (n = 101) due to allogeneic HCT at our institution between January 2011 and June 2013 were included. Three-lumen standard, nontunneled CVCs were placed via either the IJV (n = 60; 59%) or the SCV (n = 41; 41%). Study endpoints were time to local inflammation at the insertion site, time to fever, time to a combined endpoint of inflammation and fever, central line-associated bloodstream infection (CLABSI), duration of catheterization, catheter lumen obstruction, deep-vein thrombosis, pneumothorax, and catheter-related death. The median duration of catheterization per Ct superior over IJV CVCs. Moreover, local inflammation occurred earlier and more frequently in patients with an SCV CVC. The homeostasis of immune cells during immune response is vital for hosts to defend against invaders. Activating transcription factor 6 (ATF6) is an important transcription factor in the unfolded protein response (UPR) to maintaining cellular homeostasis. In the present study, one ATF6 homologue was identified from Pacific oyster Crassostrea gigas (designated as CgATF6β). The full length cDNA of CgATF6β was of 2645 bp with a 1596 bp open reading frame (ORF) encoding a polypeptide of 531 amino acids. The deduced amino acid sequence of CgATF6β was predicted to contain a transmembrane region, a conserved basic leucine zipper (bZIP) domain, a site 1 protease cleavage site, a site 2 protease cleavage site, and a Golgi localization signal. CgATF6β mRNA was constitutively expressed in hemocytes, gill, mantle, gonad, hepatopancreas and labial palp, with a slightly higher expression level in muscle (2.45-fold of that in gill, p  less then  0.05). After oysters were challenged with Vibrio splendidus, the mRNA expressio in dsGFP group, p  less then  0.05). Collectively, these results suggested that CgATF6β was involved in apoptosis inhibition of oyster hemocytes upon V. splendidus challenge by regulating the expression of CgGRP78, CgCNX and CgBcl-2. Ecto-nucleoside triphosphate diphosphohydrolases (ENTPDases) are pivotal regulators of extracellular ATP-mediated purinergic immune signaling. ENTPDase2 is a member of the cell surface-bound ecto-nucleoside triphosphate diphosphohydrolase (ENTPDase) protein family that hydrolyzes extracellular nucleoside 5'-triphosphates and nucleoside 5'-diphosphates. However, the immune relevance of ENTPDase2 in fish has not been elucidated. In the present study, from a comparative immunological perspective, we functionally characterized two ENTPDase2 transcript variants (namely ENTPDase2 and ENTPDase2a) from Japanese flounder (Paralichthys olivaceus). Sequence analysis indicates that the deduced Japanese flounder ENTPDase2 and ENTPDase2a proteins possess two conserved transmembrane domains and five apyrase conserved regions that are present in ENTPDase family proteins. However, these proteins only share 54% amino acid sequence identity. Tissue expression analysis revealed that both ENTPDase2 and ENTPDase2a mRNA transcriptsed IL-1beta expression. Taken together, our findings suggest that the two functional Japanese flounder ENTPDase2 isoforms play an essential role in the downregulation of eATP-induced proinflammatory cytokine expression in fish by degrading the available ATP levels in the extracellular milieu. Origanum sp. is a very common genus of aromatic plants worldwide distributed around the Mediterranean area and O. vulgare (oregano) is the most important species of this genus throughout the world. Due the known medicinal properties of oregano, the effect of diets enriched with 0% (control), 0.5% and 1% oregano leaves powder was studied on the growth, immune and antioxidant status of gilthead seabream (Sparus aurata L.). Fish fed with oregano 0.5% and 1% enriched diets improved both humoral (IgM and bactericidal activity in skin mucus and protease activity in serum) and cellular (head kidney leucocytes phagocytic ability) immunity at 15 and 30 days. Furthermore, the addition of oregano did not provoke any significant effect neither in the growth promotion nor in the liver antioxidant enzymes activity studied in the serum and skin mucus. The possibility of using O. vulgare as a functional additive to fish diet is discussed.
