Infection in a clavicle fracture is uncommon, but remains a challenging problem. A paucity of soft tissue coverage often combined with significant displacement and interfragmentary movement add complexity to an already difficult situation for effective infection treatment. External fixation in principle offers a means of achieving fracture stability, while the infection is being eradicated. We present the case of a closed clavicle fracture, initially treated conservatively, that presented 5 weeks later with infection...

The efficient and precise delivery of siRNA to target cells is critical to successful gene therapy. While novel nanomaterials enhance delivery efficiency, it still remains challenging for precise gene delivery to overcome nonspecific adsorption and off-target effect. Here we design a dual lock-and-key system to perform cell-subtype-specific recognition and siRNA delivery. The siRNA is self-assembled in an oligonucleotide nano vehicle that is modified with a hairpin structure to act as both the 'smart key' and the delivery carrier...

Infection is a common complication and is the second leading cause of death in hemodialysis patients. The risk of bacteremia in hemodialysis patients is 26-fold higher than in the general population, and 1/2-3/4 of the causative organisms of bacteremia in hemodialysis patients are Gram-positive bacteria. The ratio of resistant bacteria in hemodialysis patients compared to the general population is unclear. Several reports have indicated that hemodialysis patients have a higher risk of methicillin-resistant Staphylococcus aureus infection...

BACKGROUND: Primary radiochemotherapy with photons is the standard treatment for locally advanced-stage non-small cell lung cancer (NSCLC) patients. Acute radiation-induced side effects such as oesophagitis and radiation pneumonitis limit patients' quality of life, and the latter can be potentially life-threatening. Due to its distinct physical characteristics, proton therapy enables better sparing of normal tissues, which is supposed to translate into a reduction of radiation-induced side effects...

Fractures of the distal radius are very common. The majority of patients are elderly females. High impact trauma are often responsible for fractures in young men. Clinical and radiological diagnostics, including computer-assisted tomography (CAT) scan, are generally sufficient. The indication for conservative treatment is still recommended for specific fracture patterns. Application of palmar locking plates after open reduction proved to be efficacious for the majority of fracture patterns. Furthermore, precise detection and treatment of concomitant lesions are mandatory in order to prevent complications...

BACKGROUND: Phospholamban (PLN) inhibition enhances calcium cycling and is a potential novel therapy for heart failure (HF). Antisense oligonucleotides (ASOs) are a promising tool for unmet medical needs. Nonviral vector use of locked nucleic acid (LNA)-modified ASOs (LNA-ASOs), which shows strong binding to target RNAs and is resistant to nuclease, is considered to have a potential for use in novel therapeutics in the next decades. Thus, the efficacy of a single-dose injection of LNA-ASO for cardiac disease needs to be elucidated...

Targeted α therapy holds tremendous potential as a cancer treatment: it offers the possibility of delivering a highly cytotoxic dose to targeted cells while minimizing damage to surrounding healthy tissue. The metallic α-generating radioisotopes (225)Ac and (227)Th are promising radionuclides for therapeutic use, provided adequate chelation and targeting. Here we demonstrate a new chelating platform composed of a multidentate high-affinity oxygen-donating ligand 3,4,3-LI(CAM) bound to the mammalian protein siderocalin...

CONTEXT: - With the abundance of therapeutics targeted against programmed death receptor-1 and its ligand (PD-L1) that are currently approved or in clinical development, there is interest in identifying those patients most likely to respond to these drugs. Expression of PD-L1 may be an indicator of an initial and robust inflammatory response to the presence of tumor cells. Therefore, tumors that express PD-L1 may be the most likely to respond to therapies that interrupt the negative feedback mechanism that leads to PD-L1 upregulation...

BACKGROUND: Endometrial cancer is the most common cancer of the female reproductive tract. Based on our previous studies we speculated that miR-92a exhibited pro-oncogenic properties in endometrial cancer, and therefore its inhibition could be used as a therapeutic measure in this disease. Therefore in the present study we aimed to investigate both in vitro and in vivo if inhibition of miR-92a in endometrial cancer would limit cancer cells proliferation. METHODS: miR-92a expression was evaluated in four endometrial cancer cell lines using qPCR...

BACKGROUND: Central-line-associated blood-stream infection (CLABSI) is a highly consequential nosocomial infection. The most effective management includes the removal of the infected catheter. Retention of the catheter and antibiotic lock therapy (ALT) along with systemic antibiotics may be attempted only if there are unusual extenuating circumstances. CLABSIs due to Gram-negative bacteria (GNB) is more common in our setting and the organisms are often highly resistant. Hence, there is a need to explore the use of novel antimicrobials for catheter lock solutions along with antibiofilm agents...

For studies on vaccines and therapies for HIV disease, SIV-HIV chimeric viruses harboring the HIV-1 env gene (SHIVenv) remain the best virus in non-human primate models. However, there are still very few SHIVenv viruses that can cause AIDS in non-CD8-depleted animals. In the present study, a recently created CCR5-using SHIVenv_B3 virus with env gene derived from acute/early HIV-1 infections (AHI) successfully established pathogenic infection in macaques. Through a series of investigations on the evolution, mutational profile, and phenotype of the virus and the resultant humoral immune response in infected rhesus macaques, we found that the E32K mutation in the Env C1 domain was associated with macaque pathogenesis, and that the electrostatic interactions in Env may favor E32K at the gp120 N terminus and "lock" the binding to heptad repeat 1 of gp41 in the trimer and produce a SHIVenv with increased fitness and pathogenesis during macaque infections...

Motion synchrony correlates with effective and well-rated human interaction. However, people do not remain locked in synchrony; Instead, they repeatedly enter and exit synchrony. In many important interactions, such as therapy, marriage and parent-infant communication, it is the ability to exit and then re-enter synchrony that is thought to build strong relationship. The phenomenon of entry into zero-phase synchrony is well-studied experimentally and in terms of mathematical modeling. In contrast, exit-from-synchrony is under-studied...

The use of lymphocyte-depleting induction immunosuppression has been associated with a reduction in risk of AR after KT among adult recipients, particularly among high-risk subgroups such as AAs. However, data on induction regimen and AR risk are lacking among pediatric KT recipients. We examined outcomes among 7884 first-time pediatric KT recipients using SRTR data (2000-2014). Characteristics were compared across race using Wilcoxon rank-sum tests for continuous and chi-square tests for categorical variables...

BACKGROUND: Alopecia areata (AA) is an autoimmune disease characterized by hair loss mediated by CD8(+) T cells. There are no reliably effective therapies for AA. Based on recent developments in the understanding of the pathomechanism of AA, JAK inhibitors appear to be a therapeutic option; however, their efficacy for the treatment of AA has not been systematically examined. METHODS: This was a 2-center, open-label, single-arm trial using the pan-JAK inhibitor, tofacitinib citrate, for AA with >50% scalp hair loss, alopecia totalis (AT), and alopecia universalis (AU)...

Patients with intestinal failure have an increased risk for catheter-related bloodstream infections that can necessitate central venous line replacement and result in morbidity, prolonged hospitalization, or mortality. For pediatric patients with intestinal failure, the severe loss of intestinal absorptive ability leads to reliance on parenteral nutrition to meet minimal needs required for growth and development. Reliance on parenteral nutrition, in turn, forces dependency on central venous lines. Recent research concentrating on the pediatric population with intestinal failure indicates that prophylactic ethanol lock therapy can reduce the rate of catheter-related bloodstream infections and decrease central venous line removal rates in this high-risk population...

Post-traumatic osteoarthritis (PTOA) is an accelerated form of osteoarthritic cartilage degeneration affecting approximately 20-50% of patients experiencing joint injury. Currently PTOA is incurable; to better understand the etiology of PTOA and to develop rational anti-osteoarthritic therapies, it is critical to understand the spatiotemporal initiation and the progression of PTOA. In this study, we employed semi-quantitative histological scoring and quantitative damage analysis to examine disease progression in the murine destabilization of the medial meniscus (DMM) model of PTOA from early (3 days) through late- (112 days) disease timepoints...

New advances in oligonucleotide (ON) chemistry emerge continuously, and over the last few years, several aspects of ON delivery have been improved. However, clear knowledge regarding how certain chemistries behave alone, or in combination with various delivery vectors, is limited. Moreover, characterization is frequently limited to a single reporter cell line and, when different cell types are studied, experiments are commonly not carried out under similar conditions, hampering comparative analysis. To address this, we have developed a small "tissue" library of new, stable, pLuc/705 splice-switching reporter cell lines (named HuH7_705, U-2 OS_705, C2C12_705, and Neuro-2a_705)...

: The identification of epigenetic reversal agents for use in combination chemotherapies to treat human pancreatic ductal adenocarcinomas (PDAC) remains an unmet clinical need. Pharmacologic inhibitors of Enhancer of Zeste Homolog 2 (EZH2) are emerging as potential histone methylation reversal agents for the treatment of various solid tumors and leukemia; however, the surprisingly small set of mRNA targets identified with EZH2 knockdown suggests novel mechanisms contribute to their antitumorigenic effects...
