Serum protein interactions are evaluated during the drug development process since they determine the free drug concentration in blood and thereby can influence the drug's pharmacokinetic and pharmacodynamic properties. While the impact of serum proteins on the disposition of small molecules is well understood, it is not yet well characterized for a new modality, RNA interference therapeutics. When administered systemically, small interfering RNAs (siRNAs) conjugated to the N-acetylgalactosamine (GalNAc) ligand bind to proteins present in circulation. However, it is not known if these protein interactions may impact the GalNAc-conjugated siRNA uptake into hepatocytes mediated through the asialoglycoprotein receptor (ASGPR) and thereby influence the activity of GalNAc-conjugated siRNAs. In this study, we assess the impact of serum proteins on the uptake and activity of GalNAc-conjugated siRNAs in primary human hepatocytes. We found that a significant portion of the GalNAc-conjugated siRNAs is bound to serum proteins. However, ASGPR-mediated uptake and activity of GalNAc-conjugated siRNAs were minimally impacted by the presence of serum relative to their uptake and activity in the absence of serum. Therefore, in contrast to small molecules, serum proteins are expected to have minimal impact on pharmacokinetic and pharmacodynamic properties of GalNAc-conjugated siRNAs.Background Aluminum exposure may originate from numerous sources, including antiperspirants. Aluminum toxicity can cause a wide range of neurological impairments. Infants are exposed to aluminum through human milk (HM), formulas, total-parenteral-nutrition and vaccines. Due to potential risk of toxicity to both infants and women, it has been advised that lactating women decrease their use of aluminum-based products and antiperspirants. Our study aimed to determine whether the use of aluminum-based antiperspirants (ABA) affects aluminum levels in HM. Methods This cross-sectional study included healthy mothers who exclusively breastfed infants (1 week to 5 months). Questionnaires were used to collect data on demographics, antiperspirant use and aluminum exposure. Mothers were instructed to express HM during the morning at first breastfeeding session. Aluminum levels were measured by atomic absorption spectrometry with a 5 ppb limit of detection. Results Fifteen of the 58 (26%) recruited mothers used an aluminum-free antiperspirant (AFA) and 43 (74%) used an ABA. The range of aluminum concentration in HM was 0-100.8 μg/L (mean 11.4 ± 17.4 μg/L). The median aluminum level (Q1-Q3) was 6.5 μg/L (5.2-11.9) and 5.2 μg/L (3.46-9.4) in the AFA and ABA groups, respectively (p = 0.19). The aluminum levels were not affected by maternal age, education, diet, number of children, infant age, lactation stage or self-reported aluminum exposure. Conclusion The data from this preliminary study demonstrate that the use of an ABA by lactating mothers does not increase their HM aluminum content. Additional studies with a larger cohort are warranted to confirm these findings.Background Vortioxetine (Trintellix) is a serotonin modulator used in the treatment of major depressive disorder in adults. There are no data presently published on the transfer of vortioxetine into human breast milk. Case Report The present study determined the drug concentration-time profile of vortioxetine in milk samples collected from three lactating mothers, two consuming 10 mg once daily and one consuming 20 mg once daily. Milk levels were measured using liquid chromatography mass spectrometry. At a dose of 10 mg/day, the maximum concentration of vortioxetine in milk was 13.89 ng/mL. At a dose of 20 mg/day, the maximum concentration in milk was 52.32 ng/mL. The relative infant dose was calculated to be 1.1% for 10 mg dose and 1.7% for 20 mg dose. Conclusion In these three cases, we found the levels of vortioxetine in breast milk to be low and dose proportional. However, both RID's for 10 and 20 mg doses (1.1% and 1.7%, respectively) fall below the 10% theoretical level of concern and no adverse effects were reported by the mothers. selleck compound As this is a small patient sample, caution should be exercised until further studies report the safety profile of vortioxetine in breastfeeding infants.Dickeya solani is an emerging plant pathogenic bacterium, causing disease symptoms in a variety of agriculturally relevant crop species worldwide. To date a number of D. solani genomes have been sequenced and characterized, the great majority of these genomes have however come from D. solani strains isolated from potato (Solanum tuberosum L.) and not from other plant hosts. Herewith, we present the first complete, high-quality genome of D. solani strain IPO 2019 (LMG 25990) isolated from ornamental plant Hyacinthus orientalis. The genome of D. solani strain IPO 2019 consists of one chromosome of 4,919,542 bp., with a GC content of 56.2% and no plasmids. The genome contains 4502 annotated features, 22 rRNA genes, 73 tRNA genes and 1 CRISPRS. We believe that the information of this high-quality, complete, closed genome of D. solani strain isolated from host plant different than potato (i.e. hyacinth) will provide resources for comparative genomic studies as well as for analyses targeting adaptation and ecological fitness mechanisms present in Dickeya solani species.Objective Recognizing delirium phenomenology (DP) aids the early diagnosis of this syndrome and improves quality of life in patients with advanced cancer. The aim of this study was to identify the neurobehavioral and cognitive patterns of delirium-related symptoms in persons with advanced cancer. Methods We conducted an observational comparative prospective study on delirium in patients with advanced cancer in different palliative care settings, assessing the presentation/evolution of DP with the Memorial delirium assessment scale (MDAS). Results Two hundred twenty-seven patients were enrolled on hospital/hospice admission. Of these, 57 were admitted with delirium, 170 without delirium, and 31 developed delirium during hospitalization. Of the 88 patients admitted with delirium or who developed it during hospitalization, only 32 underwent two consecutive MDAS evaluations (at diagnosis and after one week). Delirium resolved in 22 patients (first average MDAS score 10.08 vs. second 3.6 [p  less then  0.001]). Disorientation, short-term memory, and memory span were altered in all patients with unresolved delirium.
