In this study, we prepared pH-sensitive hybrid nanospheres through the implementation of a facile molecularly imprinted polymer (MIP) technique combined with a UV-initiated precipitation polymerization method using vancomycin (VA) for the templates. During the course of this investigation, both 2-hydroxyethyl methacrylate (HEMA) and 2-(diethylamino) ethyl methacrylate (DEAEMA) were utilized as the functional monomers, while ethylene glycol dimethacrylate (EGDMA) was used as a cross-linker. The obtained MIP nanospheres exhibited well-controlled particle size, with a drug loading capacity of about 17%, much higher than that of the non-imprinted polymer (NIP) nanospheres (5%)...

Thymol (THY)/γ-Cyclodextrin(γ-CD) inclusion complex (IC) encapsulated electrospun zein nanofibrous webs (zein-THY/γ-CD-IC-NF) were fabricated as a food packaging material. The formation of THY/γ-CD-IC (1:1 and 2:1) was proved by experimental (X-ray diffraction (XRD), thermal gravimetric analysis (TGA), (1)H NMR) and computational techniques. THY/γ-CD-IC (2:1) exhibited higher preservation rate and stability than THY/γ-CD-IC (1:1). It is worth mentioning that zein-THY/γ-CD-IC-NF (2:1) preserved much more THY as observed in TGA and stability of THY/γ-CD-IC (2:1) was higher, as shown by a modelling study...

Transient receptor potential (TRP) ion channels are important signaling components in nociceptive and inflammatory pathways. This is attributed to their ability to function as polymodal sensors of environmental stimuli (chemical and mechanical) and as effector molecules in receptor signaling pathways. TRP vanilloid 4 (TRPV4) is a nonselective cation channel that is activated by multiple endogenous stimuli including shear stress, membrane stretch, and arachidonic acid metabolites. TRPV4 contributes to many important physiological processes and dysregulation of its activity is associated with chronic conditions of metabolism, inflammation, peripheral neuropathies, musculoskeletal development, and cardiovascular regulation...

A new pH-activated polymer chelate of cisplatin was synthesized using a scalable and green aqueous technique. Synthesis of the chelate was based on formation of a 6-member ring of platinum(II) with acetyl-homo-Lysine (Ac-homo-Lys), which was accomplished under completely aqueous conditions using a traceless photocleavable protection chemistry. Synthesis preceded by, first, amidation of a photocaged homo-Ac-Lys with hyaluronic acid (HA) in water using a p-hydroxyphenacyl (pHP) group as the photoremovable protecting group, followed by reaction of cisplatin (diaqua form) in water to form the reversible chelate...

SNARE proteins play a crucial role in intracellular trafficking by catalyzing membrane fusion, but assigning SNAREs to specific intracellular transport routes is challenging with current techniques. We developed a novel Förster resonance energy transfer-fluorescence lifetime imaging microscopy (FRET-FLIM)-based technique allowing visualization of real-time local interactions of fluorescently tagged SNARE proteins in live cells. We used FRET-FLIM to delineate the trafficking steps underlying the release of the inflammatory cytokine interleukin-6 (IL-6) from human blood-derived dendritic cells...

Incorporating therapeutic molecules into biomorphic ceramics for in situ drug release can be used to generate novel systems for tissue regeneration. These systems couple the complex hierarchical porous structures of biomorphic ceramics with the therapeutic activity of drugs. There are a large number of natural precursors available to be used as templates to obtain biomorphic silicon carbide ceramics. Additionally, different drug loading techniques can be used for these systems. The high versatility in structures and drugs allows the selection of the right structure-drug fit in each case according to the tissue needs...

BACKGROUND: It can be difficult to make complete burr holes using a perforator with automatic releasing systems in cases of a soft diploe or thick calvarial bone. OBJECTIVE: To demonstrate the utility of a flipped "bone pad" (BP) in recovery of penetration failure when using an automatic releasing perforator. METHODS: For craniotomy or ventricular drainage, the first step is to make 1 or more burr holes using a craniotome. Neurosurgeons sometimes incompletely penetrate the skull using the latest tools...

Cells constantly change their membrane architecture and protein distribution, but it is extremely difficult to visualize these events at a temporal and spatial resolution on the order of ms and nm, respectively. We have developed a time-resolved electron microscopy technique, "flash-and-freeze," that induces cellular events with optogenetics and visualizes the resulting membrane dynamics by freezing cells at defined time points after stimulation. To demonstrate this technique, we expressed channelrhodopsin, a light-sensitive cation channel, in mouse hippocampal neurons...

Insa M A Wolf, Andreas H Guse
Early Ca(2+) signaling is characterized by occurrence of Ca(2+) microdomains formed by opening of single or clusters of Ca(2+) channels, thereby initiating first signaling and subsequently activating global Ca(2+) signaling mechanisms. However, only few data are available focusing on the first seconds and minutes of Ca(2+) microdomain formation and related signaling pathways in activated T-lymphocytes. In this review, we condense current knowledge on Ca(2+) microdomain formation in T-lymphocytes and early Ca(2+) signaling, function of Ca(2+) microdomains, and microdomain organization...

Bdellovibrio bacteriovorus 109J is a Gram-negative predatory bacterium with obligate host dependency on other Gram-negative bacteria. This bacteriolytic predator collides with, enters, and establishes growth within the prey (host) periplasm, eventually lysing the prey cell wall to release fresh, motile B. bacteriovorus progeny. Laboratory maintenance of B. bacteriovorus has been previously described by other investigators. The protocols included in this unit deal with the technique required to lyophilize or freeze dry host-dependent B...

BACKGROUND: The release of damage-associated molecular pattern molecules (DAMPs) in the extracellular space secondary to injury has been shown to cause systemic activation of the coagulation system and endothelial cell damage. We hypothesized that pediatric trauma patients with increased levels of histone-complexed DNA fragments (hcDNA) would have evidence of coagulopathy and endothelial damage that would be associated with poor outcomes. METHODS: We conducted a prospective observational study of 149 pediatric trauma patients and 62 control patients at two level 1 pediatric trauma centers from 2013-2016...

In the present work, we developed a novel needleless emulsion electrospinning technique which improves the production rate of the core/shell production process. The nanofibers are based on PCL as a continuous phase combined with a droplet phase based on Pluronic F-68 (PF-68). The PCL-PF-68 nanofibers show a time-regulated release of active molecules. Needleless emulsion electrospinning was used to encapsulate diverse set of compounds to the core phase (i.e. 5-DTAF-PF68, horseradish peroxidase (HRP), TRITC-dextran, insulin growth factor I (IGF-I), transforming growth factor beta (TGF-beta) and basic fibroblast growth factor (bFGF))...

Endocrine disorders and autonomic dysfunction are common paradigms following traumatic brain injury (TBI). Alterations in the hypothalamus-pituitary-adrenal (HPA) axis following TBI may result in impaired vasopressor response, energy imbalance, fatigue, depression, or neurological disorders. Autonomic dysfunction is a common disorder following TBI. The sympathetic activity markers on HPA axis can be measured by Western blot protein analysis. Tyrosine hydroxylase, dopamine beta hydroxylase are the key enzymes for the synthesis of norepinephrine; and neuropeptide Y (NPY) is the peptide that is co-stored and co-released with norepinephrine...
