It is imperative to continue screening for breast cancer and/or detect tumor recurrence in patients after they have undergone breast augmentation or reconstruction. As there is an increasing role for both screening and diagnostic imaging of the post-operative breast, it is important for the radiologist to be familiar with the commonly performed surgical techniques in breast augmentation and reconstruction. Imaging of the augmented and reconstructed breast, as well as complications, will be reviewed with a focus on Magnetic Resonance Imaging (MRI)...

The innate immune responses of brain to vascular occlusion are primarily orchestrated by activated microglia. However, the roles of microglia in inflammatory responses to brain ischemic injuries are controversial. Here, we report a new mechanism by which microglia confer protective effects on ischemic neuronal cells. We found that under ischemic condition, the B-cell activating factor (BAFF) was vastly upregulated in microglia and this upregulation could at least be attributed to JAK-STAT signaling pathway activated by IFN-γ and IL-10, which were spatio-temporally enriched in I/R injured brain as well...

The most crucial step in the management of pleomorphic adenoma of the lacrimal gland is choosing the optimal approach for excision. We report the successful removal of a recurrent pleomorphic adenoma of the lacrimal gland in a 42-year-old woman using a specific microscope-based system of augmented reality.

Cellular growth crucially depends on protein synthesis and the abundance of translational components. Among them, aminoacyl-tRNAs play a central role in biosynthesis and shape the kinetics of mRNA translation, thus influencing protein production. Here, we used microarray-based approaches to determine the charging levels and tRNA abundance of Bacillus licheniformis. We observed an interesting cross-talk among tRNA expression, charging pattern and growth rate. For a large subset of tRNAs, we found a co-regulated and augmented expression at high growth rate...

PURPOSE: The need for mechanical inpatient bowel preparation (IBP) in reconstructive pediatric urology has come under scrutiny, secondary to literature demonstrating little benefit regarding outcomes. Starting in 2013, a majority of patients undergoing reconstructive procedures at our institution no longer underwent IBP. We hypothesized that outpatient bowel preparation (OBP) would reduce length of stay (LOS) without increasing postoperative complications after appendicovesicostomy surgery...

BACKGROUND: Mutations in the PRKAG2 gene encoding the γ-subunit of adenosine monophosphate-kinase (AMPK) cause hypertrophic cardiomyopathy (HCM) and familial-Wolff-Parkinson-White syndrome (WPW). Patients carrying the R302Q mutation in PRKAG2 present sinus bradycardia, escape rhythms, ventricular pre-excitation, supraventricular tachycardia and atrioventricular block. This mutation affects AMPK activity and increases glycogen storage in cardiomyocytes. The link between glycogen storage, WPW, HCM and arrhythmias remains unknown...

RATIONALE: Hydrogen peroxide (H2O2) is a stable reactive oxygen species (ROS) that has long been implicated in insulin signal transduction in adipocytes. However, H2O2's role in mediating insulin's effects on the heart are unknown. OBJECTIVE: We investigated the role of H2O2 in activating insulin-dependent changes in cardiac myocyte metabolic and inotropic pathways. The sources of insulin-dependent H2O2 generation were also studied. METHODS AND RESULTS: In addition to the canonical role of insulin in modulating cardiac metabolic pathways, we found that insulin also inhibited beta adrenergic-induced increases in cardiac contractility...

In recent years, rapidly evolving radiation techniques have enabled the precise delivery of very high doses of radiation to local targets with stereotactic ablative body radiotherapy (SABR). In addition to its direct cytotoxicity, radiation and in particular SABR has powerful immunomodulatory effects resulting in immunogenic cell death and potentiation of the anti-tumour immune response. However, due to the immunosuppressive nature of non-irradiated sites of metastases, radiotherapy alone is seldom sufficient to induce the systemic response required for distant tumour rejection...

BACKGROUND: Capsular contracture has been the most common complication of cosmetic breast augmentation. The effect of incision pattern on capsular contracture is still unclear. This meta-analysis demonstrates current evidence with regard to the comparison of capsular contracture rate between periareolar and other two (transaxillary and inframammary) incisions. METHODS: PubMed, EMBASE, and Cochrane databases were searched up to January 2017. The results of selected studies were meta-analyzed to obtain a pooled odds ratio of the effect of periareolar versus other two incision patterns (transaxillary or inframammary incision) of breast augmentation on capsular contracture rates...

γ-Tubulin ring complexes (γTuRCs) initiate microtubule growth and mediate microtubule attachment at microtubule-organizing centers, such as centrosomes and the Golgi complex. However, the mechanisms that control γTuRC-mediated microtubule nucleation have remained mostly unknown. Here, we show that the DNA polymerase δ catalytic subunit (PolD1) binds directly to γTuRCs and potently inhibits γTuRC-mediated microtubule nucleation. Whereas PolD1 depletion through RNA interference does not influence centrosome-based microtubule growth, the depletion augments microtubule nucleation at the Golgi complex...

BACKGROUND: Cystic fibrosis (CF) lung disease is defined by large numbers of neutrophils and associated damaging products in the airway. Delayed neutrophil apoptosis is described in CF although it is unclear whether this is a primary neutrophil defect or a response to chronic inflammation. Increased levels of neutrophil extracellular traps (NETs) have been measured in CF and we aimed to investigate the causal relationship between these phenomena and their potential to serve as a driver of inflammation...

Chorioamnionitis, premature rupture of fetal membranes (FMs), and subsequent preterm birth are associated with local infection and inflammation, particularly IL-1β production. Although bacterial infections are commonly identified, other microorganisms may play a role in the pathogenesis. Because viral pandemics, such as influenza, Ebola, and Zika, are becoming more common, and pregnant women are at increased risk for associated complications, this study evaluated the impact that viral infection had on human FM innate immune responses...

Nanotechnology based therapeutics has emerged as a promising approach for augmenting the activity of existing antimicrobials due to the unique physical and chemical properties of nanoparticles (NPs). Nickel oxide nanoparticles (NiO-NPs) have been suggested as prospective antibacterial and antitumor agent. In this study, NiO-NPs have been synthesized by a green approach using Eucalyptus globulus leaf extract and assessed for their bactericidal activity. The morphology and purity of synthesized NiO-NPs determined through various spectroscopic techniques like UV-Visible, FT-IR, XRD, EDX and electron microscopy differed considerably...

Diesel exhaust particles (DEP) and their ultrafine fraction (UFP) are known to induce cardiovascular effects in exposed subjects. The mechanisms leading to these outcomes are still under investigation, but the activation of respiratory endothelium is likely to be involved. Particles translocation through the air-blood barrier and the release of mediators from the exposed epithelium have been suggested to participate in the process. Here we used a conditioned media in vitro model to investigate the role of epithelial-released mediators in the endothelial cells activation...

REVIEW
Ichiro Hirao, Michiko Kimoto, Kyung Hyun Lee
A novel aptamer generation method to greatly augment the affinity and stability of DNA aptamers was developed by genetic alphabet expansion combined with mini-hairpin DNA technology. The genetic alphabet expansion increases the physicochemical and structural diversities of DNA aptamers by introducing extra components, unnatural bases, as a fifth base, allowing for the enhancement of DNA aptamer affinities. Furthermore, the mini-hairpin DNA technology stabilizes DNA aptamers against nuclease digestion and thermal denaturation, by introducing an extraordinarily stable mini-hairpin DNA containing a GCGAAGC sequence...

Here, we describe a novel approach that exploits an attenuated mutant of Salmonella enterica serovar Choleraesuis as carrier to deliver a plasmid encoding protein HisAK70. Subsequently, dendritic cells (DCs) were pulsed with this vaccine vector. The aim of this study was to evaluate the effectiveness of the prepared HisAK70-S. Choleraesuis-pulsed DCs (HisAK70-SAL DCs) against visceral leishmaniosis (VL). In our ex vivo model of infection, the prepared formulations could decrease parasite growth by up to 80% by augmenting the production of IL-12p40 and by reducing arginase activity (ARG)...

Polo-like kinases 1 (PLK1), a key regulator of mitosis, plays an essential role in maintaining genomic stability. Up-regulation of PLK1 was found in tumorigenesis and tumor progression of diverse cancers. However, the clinicopathological and prognostic implications of PLK1 in breast cancer (BC) have yet to be unveiled. Therefore, using PubMed, Web of Science, Embase, and Chinese databases, we conducted a meta-analysis to define the potential clinical value of PLK1 in BC. Eleven eligible articles with 2481 patients enrolled were included in the present meta-analysis, of which eight studies reported on the relationship between PLK1 expression and clinicopathological features, and nine studies provided survival data in BC patients...

DESI2 (also known as PNAS-4) is a novel pro-apoptotic gene activated during the early response to DNA damage. We previously reported that overexpression of DESI2 induces S phase arrest and apoptosis by activating checkpoint kinases. The present study was designed to test whether combination of DESI2 and IP10 could improve the therapy efficacy in vitro and in vivo. The recombinant plasmid co-expressing DESI2 and IP10 was encapsulated with DOTAP/Cholesterol nanoparticle. Immunocompetent mice bearing CT26 colon carcinoma and LL2 lung cancer were treated with the complex...
