The use of 230 nm instead of 280 nm to monitor the contribution of the capsid protein results in a linear relationship between the PA260/PA230 ratio and the percent full capsids, unlike the non-linear relationship observed when the PA260/PA280 ratio is used. As a result, the method exhibits a significantly extended assay range (up to 91% full capsids). The accuracy of the SEC-DW method was confirmed by comparing the results obtained against results from orthogonal high-resolution methods such as analytical ultracentrifugation (AUC) and cryo-electron microscopy (Cryo-EM) and excellent agreement was obtained when common samples were analyzed using the different methods. The SEC-DW method runs on a readily accessible HPLC instrument platform, provides much higher assay throughput compared to AUC and electron microscopy (EM), and can be implemented as a release method in a QC environment or used as a rapid screening tool to support process development and product understanding.Cerbera manghas L. (sea mango) is an evergreen shrub or small flowering tree up to12 m tall. It naturally occupies coastal habitats and is distributed from Seychelles in the Indian Ocean eastward to French Polynesia. In China, it is a popular ornamental urban species growing in roadside green belts, public parks, and residential areas in various coastal cities. In March 2019, powdery mildew symptoms were observed on six trees of C. manghas growing in a residential area near Minjiang University campus, in Minhou district of Fuzhou city. Approximately 60 % of leaves per plant were infected. Initial symptoms appeared as small circular to irregular white patches of superficial mycelia, conidiophores and conidia covered on both surfaces of leaves, which later coalesced and formed dense covered, resulting in discoloration and defoliation. Hyphae were septate, hyaline, smooth with simple to multilobed lobed appressoria formed singly or opposite pairs and 5 to 8 µm diam. Conidiophores were erect and 35 to 80 × 5 to 9ry Mildews).

Processing fruits infected with Paecilomyces rot can lead to juices contaminated with P. niveus ascospores. These ascospores are heat-resistant and may survive food processing and germinate in finished products. Because the fungus produces the mycotoxin patulin, juice spoilage by P. niveus is an important health hazard. Little is known about the disease biology and control mechanisms of this recently described postharvest disease. The range of fruit products contaminated by P. niveus and patulin led us to hypothesize that the host range of Paecilomyces rot is broader than previously thought. Following Koch's postulates, we determined that multiple untested rosaceous fruits and popular apple cultivars are susceptible to Paecilomyces rot infection, and that these infected fruits contain significant levels of patulin. We also observed that two closely related food spoiling fungi, Paecilomyces fulvus and Paecilomyces variotti, were unable to infect, cause symptoms in, or grow in wounded fruits. Hence, we challenge the assumption that P. niveus spoilage inoculum is introduced to foods solely through environmental sources, and show that other economically important rosaceous fruits, peaches, pears, sweet cherries and sour cherries, are susceptible to infection and can also serve as sources of spoilage inoculum. link2 Our results highlight the unique abilities of Paecilomyces niveus to infect a variety of fruits, produce patulin, and form resistant spores capable of spoiling normally shelf-stable products.
Canada is experiencing an opioid crisis. In rural areas, limited access to specialty addictions services, public transportation, and many of the social determinants of health create a unique set of challenges for people who use substances.

The Rural Outpatient Opioid Treatment (ROOT) program was created to bring some of the structure of an inpatient treatment program into a rural primary care setting in Ontario, Canada. The program uses a harm reduction approach to provide group recovery work, primary care, peer support, smoking cessation, opioid agonist therapy, screening and treatment for hepatitis C and HIV, and longitudinal follow-up. Sixteen participants have enrolled in three rounds of the ROOT program to date.

A program evaluation shows that opioid use decreased while use of other substances remained high, in particular methamphetamine use, which is increasing more broadly in the local area. Participants described feeling cared for and appreciated the 'seamless' nature of the multidisciplinary prram into rural primary care.Capsicum spp. (hot peppers) demonstrate a range of interesting bioactive properties spanning anti-inflammatory, antioxidant, and antimicrobial activities. While several species within the genus are known to produce antimicrobial peptides (AMPs), AMP sequence mining of genomic data indicates this space remains largely unexplored. Herein, in silico AMP predictions were paired with peptidomics to identify novel AMPs from the interspecific hybrid ghost pepper (Capsicum chinense × frutescens). AMP prediction algorithms revealed 115 putative AMPs within the Capsicum chinense genome, of which 14 were identified in the aerial tissue peptidome. PepSAVI-MS, de novo sequencing, and complementary approaches were used to fully molecularly characterize two novel AMPs, CC-AMP1 and CC-AMP2, including elucidation of a pyroglutamic acid post-translational modification of CC-AMP1 and disulfide bond connectivity of both. Both CC-AMP1 and CC-AMP2 have little homology with known AMPs and exhibited low μM antimicrobial activity against Gram-negative bacteria, including Escherichia coli. These findings demonstrate the complementary nature of peptidomics, bioactivity-guided discovery, and bioinformatics-based investigations to characterize plant AMP profiles.Peptide toxins find use in medicine, biotechnology, and agriculture. They are exploited as pharmaceutical tools, particularly for the investigation of ion channels. Here, we report the synthesis and activity of a novel family of peptide toxins the cystine-knotted α nemertides. Following the prototypic α-1 and -2 (1 and 2), six more nemertides were discovered by mining of available nemertean transcriptomes. Here, we describe their synthesis using solid phase peptide chemistry and their oxidative folding by using an improved protocol. Nemertides α-2 to α-7 (2-7) were produced to characterize their effect on voltage-gated sodium channels (Blatella germanica BgNaV1 and mammalian NaVs1.1-1.8). In addition, ion channel activities were matched to in vivo tests using an Artemia microwell assay. Although nemertides demonstrate high sequence similarity, they display variability in activity on the tested NaVs. The nemertides are all highly toxic to Artemia, with EC50 values in the sub-low micromolar range, and all manifest preference for the insect BgNaV1 channel. Structure-activity relationship analysis revealed key residues for NaV-subtype selectivity. Combined with low EC50 values (e.g., NaV1.1 7.9 nM (α-6); NaV1.3 9.4 nM (α-5); NaV1.4 14.6 nM (α-4)) this underscores the potential utility of α-nemertides for rational optimization to improve selectivity.Multiple myeloma (MM) is a hematological cancer in which relapse and resistance are highly frequent. Therefore, alternatives to conventional treatments are necessary. Withaferin A, a withanolide isolated from Withania somnifera, has previously shown promising activity against various MM models. In the present study, structure-activity relationships (SARs) were evaluated using 56 withanolides. The antiproliferative activity was assessed in three MM cell lines and in a 3D MM coculture model to understand the in vitro activity of compounds in models of various complexity. While the results obtained in 2D allowed a quick and simple evaluation of cytotoxicity used for a first selection, the use of the 3D MM coculture model allowed filtering compounds that perform better in a more complex setup. This study shows the importance of the last model as a bridge between 2D and in vivo studies to select the most active compounds and ultimately lead to a reduction of animal use for more sustained in vivo studies. NF-κB inhibition was determined to evaluate if this could be one of the targeted pathways. The most active compounds, withanolide D (2) and 38, should be further evaluated in vivo.The first systematic direct diversification of a complex natural product by metal-catalyzed N-H functionalization was carried out. A new series of N-(hetero)aryl analogues (1-32) of the natural anti-Alzheimer's disease drug huperzine A (HPA) was prepared via palladium-catalyzed Buchwald-Hartwig cross-coupling reactions of HPA with various aryl bromides in good yields. Most of the N-aryl-huperzine A (N-aryl-HPA) analogues showed good acetylcholinesterase (AChE) inhibitory activity in in vitro experiments. Three arylated huperzine A analogues (14, 19, and 30) exhibited stronger anti-AChE activity than HPA. link3 The 5-methoxy-2-pyridyl analogue (30) displayed the most potent AChE inhibition activity, with an IC50 value of 1.5 μM, which was 7.6-fold more active than HPA. Compound 30 also exhibited better neuroprotective activity for H2O2-induced damage in SH-SY5Y cells than HPA. Structure-activity relationship analysis suggested that the electron density of the installed aromatic ring or heteroaromatic ring played a significant role in inducing the AChE inhibition activity. Overall, compound 30 showed the advantages of easy synthesis, high potency and selectivity, and improved neuroprotection, making it a potential huperzine-type lead compound for Alzheimer's disease drug development.Structurally diverse tigliane diterpenoids have drawn significant research interest for drug discovery over many decades. Using LC-MS-guided fractionation and separation, the first phytochemical investigation on Wikstroemia lamatsoensis led to the isolation of eight tiglianes (1-8), including two new compounds, wikstrocin D (1) and wikstrocin E (2). The new structures were elucidated based on extensive physicochemical and spectroscopic analyses. The characteristic ESIMS/MS fragmentations of tiglianes 1-8 were also summarized. Among the isolated tiglianes, three compounds (8, 5, and 7) showed the most potent anti-HIV activity, with IC50 values of 0.18, 3.8, and 12.8 nM, respectively.Raman imaging has transcended in recent times from being an analytical tool to a molecular profiling technique. Biomedical applications of this technique often rely on singular-value decomposition (SVD), principal component analysis (PCA), etc. for data analysis. These methods, however, obliterate the molecular information contained in the original Raman data leading to speculative interpretations based on relative intensities. In the present study, SVD analysis of the Raman images from Penicillium chrysogenum resulted in 11 spectral components and corresponding images with highly distorted spectral features and complex image contrast, respectively. To interpret the SVD results in molecular terms, we have developed a combined multivariate approach. By applying this methodology, we have successfully extracted the contribution of five biomolecular constituents of the P. chrysogenum filamentous cell to the SVD vectors. Molecular interpretability will help SVD/PCA surpass the realm of variance-based classification to a more meaningful molecular domain.
