Ivacaftor The present study aims to investigate the influence of the freezing conditions in the material properties at different layers throughout the dried structure, in the presence and absence of a protein. Placebo and protein formulations were dried applying different cooling rates slow, fast and fast cooling with annealing. Non-uniform visual cake appearance, different pore sizes and endothermic events for release of structural water were observed throughout the cake at different freezing rates indicating heterogeneous properties of the dried material likely due to heating gradients during freezing. However, annealing increased the crystallinity and eliminated material inhomogeneities across the cake. The crystalline phase was mainly comprised of δ and hemihydrate mannitol (MHH) distributed at different ratios and influenced by the presence of the protein. The undesired formation of MHH is associated to currently used freezing temperatures or amorphous to crystalline material ratios. Thus, the correlation between the freezing step parameters and resulting material structure is a step forward to provide a better understanding of the freeze-dried cake formation and product quality improvement.3D printing, and particularly fused deposition modeling (FDM), has rapidly brought the possibility of personalizing drug therapies to the forefront of pharmaceutical research and media attention. Applications for this technology, described in published articles, are expected to grow significantly in 2020. Where are we on this path, and what needs to be done to develop a FDM 2.0 process and make personalized medicines available to patients? Based on literature analysis, this manuscript aims to answer these questions and highlight the critical technical aspects of FDM as an emerging technology for manufacturing safe, high-quality personalized oral drug products. In this collaborative paper, experts from different fields contribute strategies for ensuring the quality of starting materials and discuss the design phase, printer hardware and software, the process, the environment and the resulting products, from the perspectives of both patients and operators.Embryo transfer in cattle is a key issue requiring in vivo production of several mature follicles as opposed to the normal production of only one. In vivo produced embryos can then be transferred to recipient cows for gestation to occur. To obtain a large number of transferable embryos, the superovulation step is crucial. To allow the growth of ovarian follicles, the most commonly used protocol consists of 2 intramuscular injections per day over 4 days of a saline solution of the follicle-stimulating hormone. To reduce workload, technical errors in the injected dose and animal stress, different strategies have been investigated to sustain the release of this hormone over 4 days in 1 or 2 injections. This review introduces the physicochemical properties of the follicle-stimulating hormone and discusses the limitations of marketed products and all the research that has been conducted to overcome these limitations. In particular, the field of subcutaneous administrations, the development of new formulations such as viscous solutions, implants and microspheres and the modification of the structure of the follicle-stimulating hormone are overviewed and discussed.Developing more efficient manufacturing methods for nano therapeutic systems is becoming important, not only to better control their physico-chemical characteristics and therapeutic efficacy but also to ensure scale-up is cost-effective. The principle of cross-flow chemistry allows precise control over manufacturing parameters for the fabrication of uniform liposomal formulations, as well as providing reproducible manufacturing scale-up compared to conventional methods. We have herein investigated the use of microfluidics to produce PEGylated DSPC liposomes loaded with doxorubicin and compared their performance against identical formulations prepared by the thin-film method. The isoprenylated coumarin umbelliprenin was selected as a co-therapeutic. Umbelliprenin-loaded and doxorubicinumbelliprenin co-loaded liposomes were fabricated using the optimised microfluidic set-up. The role of umbelliprenin as lipid bilayer fluidity modulation was characterized, and we investigated its role on liposomes size, size disffectively produce uniform doxorubicinumbelliprenin co-loaded liposomal formulations with proven cytotoxicity in human breast cancer cell lines in vitro.Magnesium stearate (MgSt) is a common lubricant used in tablet formulations to facilitate tablet manufacturing by reducing ejection force. The use of MgSt in tablet formulation is known to potentially deteriorate tabletability of plastic powders and slow down drug dissolution. Here, we report surprisingly profound deterioration in tabletability of microcrystalline cellulose by hand-mixing. We also show that the hand mixing process is highly variable. To ensure the reproducibility of tabletability assessment of powders, hand-mixing should be used with caution. For research that employs hand mixing, mixing procedure should be carefully controlled and reported.Immune checkpoint inhibitors (ICIs), like monoclonal antibodies of PD-1, CTLA-4, and their ligands, are effective only in some populations of patients with cancer, because the immunosuppressive state of the tumor microenvironment (TME) in some patients cannot be effectively reversed after ICI therapy. Sialic acid (SA) receptors in the Siglec family are highly expressed on the surface of tumor-associated macrophages (TAMs) and most have immunosuppressive effects. Therefore, targeting TAMs (the siglec axis) to reverse tumor immunosuppression may provide a new direction for the development of novel tumor immunotherapies. We designed a Zoledronic acid (ZA)-loaded liposome modified by a SA-octadecylamine conjugate (ZA-SL) to act as a novel nanomedicine delivery platform. This platform can efficiently deliver ZA to TAMs through the combination of SA and Siglec-1 and exerts specific cytotoxicity or phenotypic remodeling of M2-like TAMs depending on the drug concentration in TAMs. In vivo experiments showed that ZA-SL had good TAM targeting ability, and after treatment, the S180 tumors of mice were significantly inhibited, and the proportion of M1-like TAMs was significantly higher than that of M2-like TAMs with no significant adverse reactions in mice.
