BACKGROUND: The effectiveness of hyperthermia is strongly dependent on the achieved tumour temperatures. Phased-array systems allow flexible power steering to realise good tumour heating while avoiding excessive heating in normal tissue, but the limited quantitative accuracy of pre-treatment planning complicates realising optimal tumour heating. On-line hyperthermia treatment planning could help to improve the heating quality. This paper demonstrates the feasibility of using on-line temperature-based treatment planning to improve the heating quality during hyperthermia in three patients...

Though many methods can be used to identify cell types contained in complex tissues, most require cell disaggregation and destroy information about where cells reside in relation to their microenvironment. Here, we describe a polytomous key for cell type identification in intact sections of adult mouse prostate and prostatic urethra. The key is organized as a decision tree and initiates with one round of immunostaining for nerve, epithelial, fibromuscular/hematolymphoid, or vascular associated cells. Cell identities are recursively eliminated by subsequent staining events until the remaining pool of potential cell types can be distinguished by direct comparison to other cells...

Laryngeal squamous cell carcinoma (LSCC) is one of the most common head and neck cancer, with high mortality and incidence. MicroRNA-26a (miR-26a) is involved in the development and progression of several tumors. However, the roles of miR-26a and its target CKS2 in LSCC progression are not yet clear. The mRNA and protein expression was determined using RT-PCR and Western blotting assay, respectively. Cell proliferation was detected using a Cell Counting kit-8 assay (CCK-8). Transwell assay was used to evaluate cell migration and invasion...

Antibody-mertansine (DM1) conjugates (AMCs) are among the very few active targeting therapeutics that are approved or clinically investigated for treating various cancers including metastatic breast cancer. However, none of the AMCs are effective for the treatment of triple-negative breast cancers (TNBCs). Here, we show that cRGD-decorated, redox-activatable micellar mertansine prodrug (cRGD-MMP) can effectively target and deliver DM1 to αvβ3 integrin overexpressing MDA-MB-231 TNBC xenografts in nude mice, resulting in potent tumor growth inhibition...

Reliable indicators of antimicrobial consumption (AMC) measured with harmonized data and supported with indicators for antimicrobial resistance (AMR) at herd level are necessary to target antimicrobial misuse in food producing animals. To this scope in 2010-2015 we collected AMC data in 32 Italian industrial rabbit holdings weighted with semester production and standardized with animal daily dose (ADD). Herd level AMR against eight antimicrobials was assessed in E. coli, E. faecalis and E. hirae collected in 2014 and 2015...

A multifunctional drug nanocarrier is developed by incorporating acetaldehyde-modified-cystine (AMC) into mesoporous organosilica nanoparticles (MONs), shortly termed as MONs-AMC. The anticancer drug doxorubicin (DOX) links directly to MONs-AMC through electrostatic interaction between DOX and AMC to produce a conjugate, MONs-AMC-DOX, with a drug loading efficiency of 26.24 ± 1.35%, corresponding to a loading capacity of 0.26 ± 0.01mgmg(-1) for DOX. Schiff base AMC contains a -S-S- bond and two -C˭N- bonds which cleave in the presence of certain level of GSH and in an acidic medium, providing MONs-AMC-DOX the capability for triggering pH and glutathione (GSH) dual-responsive drug release...

The activated methyl cycle (AMC) regulates the cellular levels of S-adenosyl-l-homocysteine (SAH) in bacteria, which plays a crucial role in bacterial pathogenicity. There are two AMC pathways in bacteria: one is a two-step reaction pathway (named the LuxS/Pfs pathway) in which LuxS and Pfs catalyze the conversion of SAH to l-homocysteine and autoinducer-2 (AI-2), and the other is a one-step reaction (named the SahH pathway) mediated by S-adenosyl-l-homocysteine hydrolase (SahH), which completes this cycle without producing AI-2...

We report here the sequence and functional characterization of a recombinantly expressed autoantibody (mAb 131) previously isolated from a myasthenia gravis patient by immortalization of thymic B cells using Epstein-Barr virus and TLR9 activation. The antibody is characterized by a high degree of somatic mutations as well as a 6 amino acid insertion within the VHCDR2. The recombinant mAb 131 is specific for the γ-subunit of the fetal AChR to which it bound with sub-nanomolar apparent affinity, and detected the presence of fetal AChR on a number of rhabdomyosarcoma cell lines...

Altered scapular motions premeditate shoulder impingement and other musculoskeletal disorders. Divergent experimental conditions in previous research precludes rigorous comparisons of non-invasive scapular tracking techniques. This study evaluated scapular orientation measurement methods across an expanded range of humeral postures. Scapular medial/lateral rotation, anterior/posterior tilt and protraction/retraction was measured using an acromion marker cluster (AMC), a scapular locator, and a reference stylus...

In the setting of ST-segment elevation myocardial infarction (STEMI) complicated by cardiogenic shock, three primary treatment objectives include providing circulatory support, ventricular unloading, and restoring myocardial perfusion. In addition to primary percutaneous coronary intervention, each of these three objectives can be achieved with appropriate use of an acute mechanical circulatory support (AMCS) pump. Over the past decade, utilization of percutaneously-delivered AMCS devices including the Impella axial-flow catheter, TandemHeart left atrial-to-femoral artery bypass system, and veno-arterial extracorporeal membrane oxygenation (VA-ECMO) has grown exponentially...

REVIEW

Adrenal catecholamine (CAT) secretion is a general physiological response of animals to environmental stressors such as hypoxia. This represents an important adaptive mechanism to maintain homeostasis and protect vital organs such as the brain. In adult mammals, CAT secretory responses are triggered by activation of the sympathetic nervous system that supplies cholinergic innervation of adrenomedullary chromaffin cells (AMC) via the splanchnic nerve. In the neonate, the splanchnic innervation of AMC is immature or absent, yet hypoxia stimulates a non-neurogenic CAT secretion that is critical for adaptation to extra-uterine life...

STUDY QUESTION: Is testicular growth affected by a testicular biopsy intended for fertility preservation in pre-pubertal boys with cancer? SUMMARY ANSWER: Testicular growth of the biopsied testis is not impeded in comparison to the non-biopsied contralateral testis up until 1 year after surgery. WHAT IS KNOWN ALREADY: Fertility preservation in pre-pubertal boys by means of testicular biopsy has been conducted for more than 15 years. Although immediate adverse effects of testicular biopsy are rare (1%), no data exist on the effect of biopsy on testicular growth...

BACKGROUND: Acute uncomplicated cystitis (AUC) is a common ailment in the urological setting. Guidelines for urinary tract infections are based on large-scale multi-centre, epidemiological and international studies. The objective of this observational study was to establish whether the results of a multi-centre study on the resistance profile of Escherichia coli (E. coli) in patients with AUC could be directly applied to an urological practice in a major European city or whether there are divergences in the resistance profile...

Motivation: In genetic association studies, meta-analyses are widely used to increase the statistical power by aggregating information from multiple studies. In meta-analyses, participating studies often share the same individuals due to the shared use of publicly available control data or accidental recruiting of the same subjects. As such overlapping can inflate false positive rate, overlapping subjects are traditionally split in the studies prior to meta-analysis, which requires access to genotype data and is not always possible...

During the Ebola Virus Disease (EVD) epidemic in West Africa (2014-2016), many faculty, staff, and trainees from U.S. academic medical centers (i.e., teaching hospitals and their affiliated medical schools; AMCs) wished to contribute to the response to the outbreak, but many barriers prevented their participation. Here, the authors describe a successful long-term academic collaboration in Liberia that facilitated participation in the EVD response. This Perspective outlines the role the authors played in the response (providing equipment and training, supporting the return of medical education), the barriers they faced (logistical and financial), and elements that contributed to their success (partnering and coordinating their response with both U...
