Attempts to develop cell-based cancer vaccines have shown limited efficacy, partly because transplanted dendritic cells (DCs) do not survive long enough to reach the lymph nodes. The development of biomaterials capable of modulating DCs in situ to enhance antigen uptake and presentation has emerged as a novel method toward developing more efficient cancer vaccines. Here, we propose a two-step h...

The majority of the good DNA editing techniques have been developed in Escherichia coli; however, Bacillus subtilis is better host for a plethora of synthetic biology and biotechnology applications. Reliable and efficient systems for the transfer of synthetic DNA between E. coli and B. subtilis are therefore of the highest importance. Using synthetic biology approaches, such as streamlined lamb...

Lesion and thermal stimulation studies suggest that temperature regulation is controlled by a hierarchy of neural structures. Effector areas for specific thermoregulatory responses are located throughout the brain stem and spinal cord. The preoptic region, in and near the rostral hypothalamus, acts as a coordinating center and strongly influences each of the lower effector areas. The preoptic a...

A thermosensitive sporulation mutant was used to determine the order of sporulation operonsin the urs region of the Bacillus subtilis chromosome. Data from three-factor transformation crosses and three- and four-factor transduction crosses established the order metC-SPO-96(SpoII)-spo-85(SpoV)-spo-279(SpoII)-furA-ura-cysC-spo-NG1.67(SpoIII). Previously, furA was thought to lie to the right of ur...

The objective of the present chapter is to provide the basic concepts and tools required to understand the inception and development of cavitation in liquid flows. The influence of various parameters as the boundary layer and nuclei content is discussed. A special attention is given to thermal effects which may significantly influence the development of cavitation in thermosensitive fluids as c...

The radical copolymerization of N-[3-(dialkylamino)-propyl]methacrylamides with a number (meth)acrylic amides and esters in organic solvents over wide range molar ratios has been studied. Co-polymerisation constants for five polymerisation systems 1,4-dioxane toluene have determined by the Feinman Ross method. influence solvent on kinetics studied monomers was found, which manifests itself chan...

BACKGROUND The periodontitis is one of the most prevalent diseases with alveolar resorption in adult people and is the main cause of the tooth loss. To investigate the possibility for protecting the loss of alveolar bone in periodontal diseases, a RNAi-based therapeutic strategy is applied for silencing RANK signaling using thermosensitive chitosan hydrogel as siRNA reservoir and vector. RESU...

The incidence of spinal cord injury (SCI) has been gradually increasing, and the treatment has troubled the medical field all the time. Primary and secondary injuries ultimately lead to nerve impulse conduction block. Microglia and astrocytes excessively accumulate and proliferate to form the glial scar. At present, to reduce the effect of glial scar on nerve regeneration is a hot spot in the r...

Lack of mucoadhesive properties is the major drawback to poloxamer 407 (F127)-based in situ hydrogels for mucosal administration. The objective of the present study was to construct a novel mucoadhesive and thermosensitive in situ hydrogel drug delivery system based on an amino-functionalized poloxamer for vaginal administration. First, amino-functionalized poloxamer 407 (F127-NH2) was synthesi...
