The assembled phage genome size is 50,013 bp, with 62.7% of G + C content.  https://www.selleckchem.com/products/act001-dmamcl.html  SWU2 genome sequence shares 88% identity with Mycobacterium phages HINdeR and Timshel, differing in substitutions, insertions and deletions in SWU2. Phylogenetic tree revealed that SWU2 is grouped into A7 sub-cluster. There are several substitutions, insertions and deletions in SWU2 genome in comparison with close cousin phages HINdeR and Timshel. The new phage adds another dimension of abundance to the mycobacteriophages.The volume change on melting is a rarely studied quantity and it is not well understood even if it must reflect the changes in interaction between the solid and the liquid state. It is part of the solid-state information for materials and pharmaceuticals and it is important for the reliability of polymorph stability study results. Using the crystal structure of monoclinic tetrazepam at 150 K and at room temperature, in addition to powder X-ray diffraction as a function of the temperature, the specific volume of tetrazepam has been determined over a large temperature domain. In combination with a pressure-temperature curve for the melting of tetrazepam, its volume change on melting could be determined. With this information and previous data from the literature, the assumption that the volume of the solid increases on average with 11% on melting has been investigated. It can be concluded that this value is not constant; however so far, no simple relationship has been found to relate the solid state to its volume change on melting and using 11% remains best practice. A comparison of the tetrazepam crystal structure with diazepam and nordiazepam has been provided too.Lecithin coated cholesteryl oleate (ChOl) based nanoparticles (NPs) imitating natural lipoproteins represent a new and promising drug carrier strategy to cross the blood-brain barrier (BBB). In such systems lecithin serves as stabilizing as well as functionalizing agent and enables the adsorptive binding of apolipoprotein E3 (ApoE) as potential drug targeting ligand. The present work is focused on the effect of size reduction on the lecithin coating and ApoE binding. Furthermore, the transferability of this lecithin coating strategy to other NP cores, namely polylactic-co-glycolic acid (PLGA) and polylactic acid (PLA), is investigated in order to provide a universal strategy for a wide range of cores to overcome the BBB. The ChOl NPs' size was successfully reduced from 100 nm to 70 nm. Varying the core size of ChOl NPs illustrated, that the at least needed lecithin amount for sufficient stabilization could be calculated surface area dependently. However, the size reduction led to reduced dye loading per NP and increased ApoE need per NP mass. These effects turned out as huge disadvantages of smaller NPs by weakening the observed ApoE mediated effects. Nevertheless, the extended understanding of the lecithin coating could be used to transfer the concept to other core materials. PLGA and PLA NPs were investigated as alternative core materials for lecithin coating. PLGA was found to be unsuitable, whereas in the case of PLA sufficient stabilization and 100% adsorptive binding efficiency to ApoE could be achieved. The ApoE mediated effects of transcytosis at an in vitro BBB model by bypassing lysosomes were reproduced in even stronger quantities than with a ChOl core, proving lecithin coating as transferable strategy to disguise various NPs with a certain lipophilicity as lipoproteins.Functional peptides that are made up of diverse endogenous amino acids with a specific sequence and length have shown various functionalities including specific biological recognition and cell penetrating ability for biomedical applications. Therefore, incorporation of peptide with a certain tailor-made amino acid sequence to the delivery systems has endowed the resulting delivery vehicles with specific functions, which provided a robust strategy for enhancing the therapeutic efficiency for malignant diseases. To make a timely review on this hot subject of research, we summarized the recent progress on peptide-functionalized delivery vehicles for enhanced cancer therapy with an emphasis on the chemistry adopted for the conjugation of peptide compared to most of the published reviews with a focus on the property and performance of the peptide-functionalized delivery systems. The primary synthetic strategies used for peptide conjugation were first summarized. An exhibition of four different types of peptide-functionalized delivery vehicles were next presented following a classification standard of the functions of each peptide category including tumor-targeting peptide, cell-penetrating peptide, subcellular organelle-targeting peptide and tumor-penetrating peptide. A concluding remark on the future direction of this rapidly developing research field was made finally. The important principles on the design of peptide, screening of the conjugation strategy, and optimization of peptide property that were drawn from the detailed comparison of the representative literature in this review will provide useful guidelines for the future development of advanced peptide-functionalized delivery platforms with enhanced therapeutic efficiency for cancer therapy.The development of a scaffold matrix that can inhibit bacterial infection and promote wound healing simultaneously is an essential demand to improve the health care system. Hydroxyapatite (HAP) doped with different concentrations of silver ions (Ag+) were incorporated into electrospun nanofibrous scaffolds of polycaprolactone (PCL) using the electrospinning technique. The formed phase was identified using XRD, while the morphological and roughness behavior were investigated using FESEM. It was shown that scaffolds were configured in randomly distributed nanofibers with diameters around of 0.19-0.40, 0.31-0.54, 1.36, 0.122-0.429 μm for 0.0Ag-HAP@PCL, 0.2Ag-HAP@PCL, 0.6Ag-HAP@PCL, and 0.8Ag-HAP@PCL, respectively. Moreover, the maximum roughness peak height increased significantly from 179 to 284 nm, with the lowest and highest contributions of Ag. The mechanical properties were examined and displayed that the tensile strength increased from 3.11 ± 0.21 MPa to its highest value at 3.57 ± 0.31 MPa for 0.4Ag-HAP@PCL.
