Hypoxia plays vital roles in the development of tumor resistance against typical anticancer therapies and local reoxygenation has proved effective to overcome the hypoxia-induced chemoresistance. Perfluorocarbon (PFC) is an FDA approved oxygen carrier and currently vigorously investigated for oxygen delivery to tumors. This study reports a perfluorocarbon and etoposide (EP) loaded porous hollow Fe3O4-based theranostic nanoplatform capable of delivering oxygen to solid tumors to enhance their susceptibility against EP. Results show that oxygen could be released at a moderate rate from the porous hollow magnetic Fe3O4 nanoparticles (PHMNPs) over an extended period of time, therefore effectively reducing the hypoxia-induced EP resistance of tumor cells. Moreover, the surface of PHMNPs was modified with lactobionic acid (LA)-containing amphiphilic polymers via hydrophobic interaction, which could provide targeting effect against certain types of tumors. The hydrophilic moiety would be subsequently shed by the intratumoral GSH after cellular internalization and result in the agglomeration of nanocarriers inside tumor cells, consequently impeding the nanoparticle exocytosis to enhance their intracellular retention. The enhanced retention could elevate the intracellular EP level and effectively boost the tumor cell killing effect. In addition to the therapeutic benefits, the Fe3O4 nanocage could also be used for the magnetic resonance imaging of the tumor area. The assorted benefits of the composite nanosystem are anticipated to be advantageous for the treatment of drug-resistant hypoxic tumors.

Recently, interest in stimuli-responsive core-shell nanogels as drug delivery systems for tumor therapy has increased. Here, a temperature-activated drug locking and glutathione-triggered drug unlocking nanogel is designed, which is composed of hyaluronic acid (HA) conjugated with poly(N-isopropylacrylamide) (PNIPAAm) using a disulfide bond as the linker (HA-SS-PNIPAAm, H-SS-P). After injection into the systemic circulation, these synthetic copolymers endure temperature-motivated lock behaviors to form nanogels due to the thermosensitive lipophilic transformation of PNIPAAm, accompanied by doxorubicin (DOX) locking into the cavities of the nanogels. When they reach tumor cells, these nanogels exhibit glutathione (GSH)-triggered opening behavior to unlock the drugs for tumor therapy. The transmission electron microscopy (TEM) results demonstrate that the H-SS-P copolymer solutions are irregular at room temperature, while spherical structures (similar to 30 nm) can be observed below 37 degrees C, but dissociate in the presence of 40 mM GSH. Based on flow cytometry and fluorescence microscopy analyses, observations reveal that H-SS-P@DOX nanogels are intracellularly taken up into human lung cancer cells (A549) via HA-receptor mediated endocytosis. More importantly, these nanogels possess much higher tumor targeting capacity than free DOX and efficiently enhance the antitumor effect with reduced systemic toxicity in 4T1 tumor-bearing mice.

Background Turf toe injuries, though most common in athletes, can also occur in non-athletes. No study exists in the current literature investigating operative outcomes in non-athlete patients with chronic turf toe injury. In this study, we present our outcomes on operatively treated turf toe injuries in non-athletes in the only cohort yet studied. Methods Using ICD-10 codes, we assembled a cohort of 12 patients who underwent operative repair of chronic turf toe injury from January 2012 through January 2018 at the investigating institution. These 12 patients were evaluated to determine demographic information, method of injury, length of time from injury to surgery, clinical and radiologic characteristics of the injury, and operative outcomes including mean preoperative and postoperative VAS (Visual Analog Scale) scores, preoperative and postoperative FFI (Foot Function Index) scores, and postoperative complications. Results On initial clinical presentation, all 12 patients had local tenderness with associated painful range of motion. Four patients had restricted range of motion, all patients had a positive Lachman test, two had local edema, and eight had hallux valgus deformity. Mean VAS improved from 4.6 (range 2-9) to 1 (range 0-4). Mean FFI improved from 102.5 (range 56-177) to 61.75 (range 23-144). All patients had a negative Lachman test at final follow-up. No patients developed major complications or required revision surgery. Conclusions Our study is the first to investigate operative outcomes following chronic turf toe injury in non-athlete patients. Based on our study, surgeons and patients can expect significant improvement in overall pain and function following surgery.

Clinical application of drug cocktails for cancer therapy is limited by their severe systemic toxicity. To solve a catch-22 dilemma between safety and efficacy for drug cocktails, a heterotargeted nanococktail (PPPDMA) with traceless linkers is developed. In the PPPDMA nanogel, a heterotargeting strategy is employed to improve its tumor selective targeting efficacy by overcoming the cancer cell monoligand density limitation. Benefitting from its glutathione and reactive oxygen species responsiveness, the loaded paclitaxel and doxorubicin can be quickly and tracelessly released into the cytoplasm in their original form, which bestows upon PPPDMA nanogels the capability to overwhelm the processing capacity of the cancer cell’s P-glycoprotein efflux pump, and ultimately kill them without inducing side effects. The PPPDMA treatment reduced its tumor burden over 99% (in tumor weight) and 96% (in tumor number). Most importantly, no detectable tumor in more than half of the PPPDMA treated mice was observed. It is concluded that traceless linker and heterotargeted nanococktail strategy can be a safe and effective approach for cancer treatment.

A triply responsive amphiphilic polymer containing poly (ethylene glycol) (PEG) and pyrene linked by a disulfide bond (PEO-SS-PY) was synthesized. Benefiting from its amphiphilicity, PEO-SS-PY could self-assemble into 126 nm micelles in water. PEO-SS-PY with CB[7] forms a 1:1 pseudorotaxane polymer (PEO-SS-Py@CB[7]) in aqueous solution. After the formation of host-guest complex, the micelles size increased to 136 nm and the fluorescence emission intensity increased. Glutathione would break the disulfide bond, leading to the dissociation of the micelles. Spermine and adamantanamine hydrochloride would dissociate the host-guest complex, leading to change of micelle size and decrease of fluorescence intensity. More interestingly, this self-assembly micelle displayed highly sensitive response to Fe3+. Because the effective absorption of Fe3+ hindered the absorption of PEO-SS-Py@CB[7] at the excitation wavelength of 405 nm, Fe3+ distinctly quenched the fluorescence emission of PEO-SS-Py@CB[7], whereas, a very low changes of intensity was observed for other metal ions. Results of this paper provide a new idea for the combination of metal ion detection and controlled release.

Monoamino cyclic tellurides with a five-or six-membered ring structure and their derivatives were developed as a new class of catalyst for the oxidation of organothiols to organodisulfides in a glutathione peroxidase-like catalytic reaction. Quantitative conversion and high reaction rate were achieved by performing the reaction in an organic-aqueous segmented microflow system. Importantly, the process circumvented product purification, which is a major limitation of current organodisulfide synthetic methods.

Integrating multimodality bioimaging and multiple stimuli-responsive controlled drug release properties into one single nanosystem for therapeutic application is highly desirable but still remains a challenge. Herein, we coated a hollow mesoporous silica shell on to upconversion nanoparticles (UCNPs) and conjugated pillarene-based supramolecular valves on to surface of UCNPs@hm-SiO2 using amine-coumarin phototriggers to obtain the multifunctional nanoparticles, UCNPs@hm-SiO2-Cou-Cys-DOX/WP[5]. Benefiting from the core shell structured UCNPs, the UCNPs@hm-SiO2-Cou-Cys-DOX/WP[5] can serve as efficient contrast agents for upconversion luminescence and T-1-weighted magnetic resonance imaging in vitro/in vivo. More importantly, depending on exquisitely designed supramolecular valves, UCNPs@hm-SiO2-Cou-Cys-DOX/WP[5] can realize zero-premature release under normal physiological conditions (pH 7.4), which produces minimal damage to normal tissue, whereas this nanosystem can respond to several disease-related signals, including acid (most cancers), alkali (metabolic alkalosis), and Zn2+ (Alzheimer’s disease), along with two external stimuli, including near-infrared (NIR) light and reductive electrical potential, via altering the spatial structure of pseudorotaxanes, disassembling the molecular stalks, or undergoing photochemical reactions, ultimately resulting in opening of the gatekeepers and release of encapsulated drugs. The multifunctional UCNP-based nanoparticles were endowed with such quintuple stimuli-responsive controlled release characteristics. Specifically, in anticancer application, the rational utilization of the two of them, acid and NIR light, could regulate the release amount and rate of DOX from UCNPs@hm-SiO2-Cou-Cys-DOX/WP[S], accelerate the accumulation of DOX in cell nuclei, and thereby promote the cancer cell apoptosis, indicating that the nanomaterials have promising application in cancer treatment. This study provides a novel design strategy for constructing multifunctional UCNP-based nanoparticles with multiple stimuli-responsive drug release features, which have great potential in diagnosis and therapy of relevant diseases as theranostic nanomedicines.

Multidrug resistance (MDR) of cancer cells is a significant challenge in chemotherapy, highlighting the urgent medical need for simple and reproducible strategies to reverse this process. Here, we report the development of an active tumor-targeting and redox-responsive nanoplatform (PA-ss-NP) using hyaluronic acid-g-cystamine dihydrochloride-poly-epsilon-(benzyloxycarbonyl)-L-lysine (HA-ss-PLLZ) to co-deliver paclitaxel (PTX) and apatinib (APA) for effective reversal of MDR. This smart nanoplatform specifically bound to CD44 receptors, leading to selective accumulation at the tumor site and uptake by MCF-7/ADR cells. Under high concentrations of cellular glutathione (GSH), the nanocarrier was degraded rapidly with complete release of its encapsulated drugs. Released APA effectively inhibited the function of the P-glycoprotein (P-gp) drug pump and improved the sensitivity of MDR cells to chemotherapeutic agents, leading to the recovery of PTX chemosensitivity in MDR cells. As expected, this newly developed intelligent drug delivery system could effectively control MDR, both in vitro and in vivo.
