    , indicating lineage-specific expansion of MTPSL genes in lineages leading to R.lindenbergiana and M. polymorpha. This study strengthens evidence for the contribution of MTPSL genes to terpenoid biosynthesis in liverworts.Applying a positive psychology perspective, this study aimed to identify potential intra-individual factors that might protect against the development of disordered eating in a community sample of young women and men (N = 510; 56 % women; Mage = 24.3). Based on existing literature, the study included the general resilience factors of self-esteem and identity coherence as well as two dimensions of positive embodiment (positive body connection and comfort, and agency and functionality). All factors were negatively correlated with disordered eating among women and men. Hierarchical regression analyses indicated that positive embodiment, specifically positive body connection, was a significant predictor of lower degrees of disordered eating symptoms in both women and men, followed by self-esteem. The overall prediction model accounted for 42.6 % in the variation of disordered eating symptoms for women and 23.9 % for men. Prevention and treatment interventions promoting health factors that protect against the development of eating disorders are much needed. The present study informs such efforts by emphasizing the promotion of positive embodiment.The subcellular characteristics of phytoplasma-infected jujube (Ziziphus jujuba) leaves were investigated using transmission electron microscopy. Midrib fragments of witches’ broom-diseased jujube leaves were collected from abnormally small leaves at an early stage of branch clustering. The diseased jujube leaves showed multivesicular bodies (MVBs) with vesicles and tubules in the phloem parenchyma cells and sieve elements. The MVBs were connected to the plasma membrane appressed to the cell wall. There were increased callose collars at the pore-plasmodesma unit ends of the sieve elements in the diseased leaves than in control leaves. The proliferation of MVBs in the diseased jujube leaves could be associated with endoplasmic reticulum stress-dependent exosome release. The phytoplasma produced pleomorphic cells in sieve elements. Several types of putative extracellular structures were observed on the phytoplasma cells (i) fimbriae-like threads, (ii) pili-like projections, (iii) flagella-like appendages, and (iv) tube-like structures. This study provides novel insights into intracellular obligate cell wall-less prokaryotes and host phloem structures.Black phosphorus quantum dots(BPQDs) have shown a good application prospect in the field of tumor therapy due to their photoelectric effect and good biodegradability. Due to the active endocytosis and fast metabolic efficiency of tumor cells, BPQDs are easy to be absorbed by tumor cells. However, this does not guarantee that BPQDs will be completely targeted to tumor cells, and normal cells will also absorb BPQDs. Because the cell membrane is negatively charged, BPQDs are also negatively charged and are not easily absorbed by cells under the action of electrostatic repulsion. Surface pegylation is the most common modification method of black phosphorus at present. However, surface pegylation can reduce the uptake of BPQDs by tumor cells. Positive PEG is also easy to be recognized and swallowed by the reticuloendothelial system. The inherent instability and poor tumor targeting of BPQDs under physiological conditions limit further research and clinical application. For this purpose, we selected cationic polymer polyethylenimine (PEI) to modify BPQDs and then added RGD peptides targeting tumor cells. An outer layer of negatively charged PEG+DMMA makes the nanosystem more stable . In the acidic environment of the tumor, the PEG layer has a charge reversal, and the positively charged PEI and the RGD polypeptide BPQDs targeted by the tumor cells are released into the tumor cells. It provides a new method for efficiently and accurately transporting BPQDs, a novel photosensitive nanomaterial, into tumor cells for photodynamic therapy.Heparin has served as a mainstream anticoagulant for over eight decades. Brigatinib Clinically heparin-derived compounds significantly contribute to prevention and treatment of thrombotic events complicated in numerous medical conditions such as venous thromboembolism, coronary artery disease and extracorporeal circulation processes. Moreover in recent years, various off-labeled efficacious potentials of heparin beyond anti-coagulation are dramatically emerging, and increasingly investigated in clinical studies. Herein this article presents a comprehensive update on the expanded applications of heparin agents, covering the pregnant clinic, respiratory inflammation, renal disease, sepsis, pancreatitis, among others. It aims to maximize the beneficial profile of a pharmaceutical product through medical re-purposing development, exemplified by heparin, to address the unmet clinical needs of severe illness including coronavirus disease 2019 (COVID-19).Patients with localized prostate cancer comprise a large volume of treatments in radiation therapy centers. Occasionally, individual patient anatomy makes the safe delivery of an effective dose of radiation therapy challenging. We describe 2 cases of patients with a small bowel deep in the pelvis within the planning target volume with subsequent suboptimal radiation therapy treatment plans. We explore how we used the GU-Lok, a prostate immobilization device, to move the small bowel away from the prostate, and tighten target volume margins to help facilitate safe and effective treatment.The SARS-CoV-2 virus causes the coronavirus disease 19 emerged in 2020. The pandemic triggered a turmoil in public health and is having a tremendous social and economic impact around the globe. Upon entry into host cells, the SARS-CoV-2 virus hijacks cellular machineries to produce and maintain its own proteins, spreading the infection. Although the disease is known for prominent respiratory symptoms, accumulating evidence is also demonstrating the involvement of the central nervous system, with possible mid- and long-term neurological consequences. In this study, we conducted a detailed bioinformatic analysis of the SARS-CoV-2 proteome aggregation propensity by using several complementary computational tools. Our study identified 10 aggregation prone proteins in the reference SARS-CoV-2 strain the non-structural proteins Nsp4, Nsp6 and Nsp7 as well as ORF3a, ORF6, ORF7a, ORF7b, ORF10, CovE and CovM. By searching for the available mutants of each protein, we have found that most proteins are conserved, while ORF3a and ORF7b are variable and characterized by the occurrence of a large number of mutants with increased aggregation propensity.
