4-6 Weeks Old Female C57BL/6 Mice Obtained from Jackson Labs Were Used for Cell Isolation
Methods Mice: 4-6 weeks old female C57BL/6 mice obtained from Jackson labs were used for cell isolation. Female Foxp3-IRES-GFP reporter mice (1), backcrossed to B6/C57 background for 10 generations, were used for the isolation of naïve CD4 and naïve CD8 cells for the RNAseq experiments. The mice were housed in pathogen-free animal facility in the La Jolla Institute for Allergy and Immunology and were used according to protocols approved by the Institutional Animal Care and use Committee. Preparation of cells: Subsets of thymocytes were isolated by cell sorting as previously described (2), after cell surface staining using CD4 (GK1.5), CD8 (53-6.7), CD3ε (145- 2C11), CD24 (M1/69) (all from Biolegend). DP cells: CD4+CD8 int/hi; CD4 SP cells: CD4CD3 hi, CD24 int/lo; CD8 SP cells: CD8 int/hi CD4 CD3 hi, CD24 int/lo (Fig S2). Peripheral subsets were isolated after pooling spleen and lymph nodes. T cells were enriched by negative isolation using Dynabeads (Dynabeads untouched mouse T cells, 11413D, Invitrogen). After surface staining for CD4 (GK1.5), CD8 (53-6.7), CD62L (MEL-14), CD25 (PC61) and CD44 (IM7), naïve CD4+CD62L hiCD25-CD44lo and naïve CD8+CD62L hiCD25-CD44lo were obtained by sorting (BD FACS Aria). Additionally, for the RNAseq experiments, CD4 and CD8 naïve cells were isolated by sorting T cells from the Foxp3- IRES-GFP mice: CD4+CD62LhiCD25–CD44lo GFP(FOXP3)– and CD8+CD62LhiCD25– CD44lo GFP(FOXP3)– (antibodies were from Biolegend). In some cases, naïve CD4 cells were cultured in vitro under Th1 or Th2 polarizing conditions (3, 4). -

Molecular chaperones play important roles in all cellular organisms by maintaining the proteome in an optimally folded state. They appear to be at a premium in cancer cells whose evolution along the malignant pathways requires the fostering of cohorts of mutant proteins that are employed to overcome tumor suppressive regulation. -

Nanotechnology will affect our lives tremendously over the next decade in very different fields, including medicine and pharmaceutical Sciences. Most of the available drugs now are lipophilic in nature and this stands as challenging aspect faced for scientists to formulate and deliver for better efficacy, so nanoparticles, nanosuspension, nanocapsules are used now days to deliver these drugs with greater bioavailability and also have been adopted to improve the solubility of poorly soluble drugs. The use of nanoparticles is an universal formulation approach to increase the therapeutic performance of drugs in any route of administration. This review article describes the preparation methods, physicochemical -
A Gellan-Based Fluid Gel Carrier for Spray Delivery

Abstract Autologous cell transplantation is a promising approach to enhance burn wound re- epithelialisation. It was introduced to clinical practice decades ago with current delivery techniques involving spraying autologous cultured or uncultured cells in low-viscosity sus- pensions. This delivery method is limited since it results in an uneven distribution on the wound bed and cell loss as the liquid is not retained on the skin surface. In this thesis, a sprayable gel that solidifies on the surface of the skin has been developed to circumvent this problem. A gellan-based fluid gel system was developed with flexible viscoelastic properties that can be tuned by a biocompatible polymer concentration and ionic strength to facilitate spray delivery. The material liquefies at high shear during spraying with self-healing properties of the gel causing it to solidify on the receiving sur- face. -

Powders are intimate mixtures of dry, finely divided drugs and/or chemicals that may be intended for internal or external use. Advantages/Disadvantages flexibility in compounding good chemical stability Ease of administration time-consuming not well-suited to dispense unpleasant tasting, hygroscopic or deliquescent drugs inaccuracy of dose Types Medicated Aerosol Preparation Weighing of ingredients Comminuting Blending or mixing Weighing of individual dose Materials Active ingredients Packaging Types of material used to pack/dispense divided powders Foil plastic bag used for volatile vegetable parchment thin, semiopaque, moisture-resistant white bond without moisture-resistant properties Glassine glazed, transparent, moisture-resistant paper used for volatile to a certain extent Waxed transparent-water-proof paper used for hygroscopic and volatile drugs Seidlitz powder is the name with which is commonly known a medication composed by a mixture of tartaric acid, sodium bicarbonate, and potassium sodium tartrate, used as a mild cathartic by dissolving in water and drinking. After ingestion, the powder combines with gastric juices developing intestinal gases which are somewhat helpful in evacuating the bowels. This medication's name comes from the Seidlitz Saline Springs of Bohemia (now Sedlčany in the Czech Republic), which were rather famous in Europe at the time this medication was first marketed in the late 19th century, even though the foregoing laxative constituents do not represent those of the springs named. Use of Each ingredient – act as acid and base which react in the presence of water to cause effervescence Use of Preparation - mild cathartic/laxative Appearance – white powder Storage – store in air tight containers Granules are prepared agglomerates of powdered materials, may be used per se for the medicinal value of their content or they may be used for pharmaceutical purposes, as in making tablets. -

Glioblastoma Treatments: an Account of Recent Industrial Developments

Their different modes of action are analyzed with a distinction being made between the effects of radiation, the targeting of specific parts of glioma cells, and immunotherapy. Most of them are still at a too early stage of development to firmly conclude about their efficacy. Optune, which triggers antitumor activity by blocking the mitosis of glioma cells under the application of an alternating electric field, seems to be the only recently developed therapy with some efficacy reported on a large number of GBM patients. The need for early GBM diagnosis is emphasized since it could enable the treatment of GBM tumors of small sizes, possibly easier to eradicate than larger tumors. Ways to improve clinical protocols by strengthening preclinical studies using of a broader range of different animal and tumor models are also underlined. Issues related with efficient drug delivery and crossing of Edited by: blood brain barrier are discussed. Finally societal and economic aspects are described François E.
