BACKGROUND: Despite over 6 million subjects contributing to the National Marrow Donor Program human leukocyte antigen (HLA) haplotype frequency reference data (HFD), haplotypes cannot be predicted from the HLA assignments of some patients searching for an unrelated donor (URD) in the Be The Match Registry®. We aimed to determine the incidence of these patient searches and whether haplotypes lacking from the HFD can be found among the low-resolution typed URD pool. MATERIALS AND METHODS: New NMDP searches with uncommon patient haplotypes (UPH), defined as a lack of haplotype pairs in any single ethnic group in the HFD based upon HLA-A˜C˜B˜DRB1˜DQB1, were identified...

BACKGROUND: Enhanced recovery pathways (ERPs) have been shown to aid in patient recovery and improve outcomes in many surgical settings. At present, there is limited data available regarding the use and feasibility of ERPs for patients undergoing microsurgical breast reconstruction. We sought to assess patient outcomes before and after the introduction of an ERP that was adopted by multiple surgeons at a single cancer center. METHODS: A multidisciplinary ERP was developed for patients undergoing deep inferior epigastric perforator (DIEP) or muscle-sparing free transverse rectus abdominis myocutaneous (TRAM) flap breast reconstruction...

RNA is a functionally versatile polymer but suffers from susceptibility to spontaneous or RNase-catalyzed degradation. This vulnerability makes it difficult to preserve RNA for extended periods of time, which limits its use in various contexts, including practical applications of functional nucleic acids. Here we present a simple method to preserve RNA by pullulan (a complex sugar produced by Aureobasidium pullulans fungus) film formation. This strategy can markedly suppress both spontaneous and RNase-promoted degradation...

Nuclear receptors (NRs) have been targets of intensive drug development for decades due to their roles as key regulators of multiple developmental, physiological and disease processes. In breast cancer, expression of the estrogen and progesterone receptor remains clinically important in predicting prognosis and determining therapeutic strategies. More recently, there is growing evidence supporting the involvement of multiple nuclear receptors other than the estrogen and progesterone receptors, in the regulation of various processes important to the initiation and progression of breast cancer...

BACKGROUND: The incidence of breast cancer (BC) cases has increased significantly. The number of breast reconstruction (BR) procedures performed has mirrored this trend. Although implant-only procedures remain the most commonly used type of immediate BR, autologous techniques involving donor sites account for approximately 20%. The aim of this study was to assess national and regional trends in different types of autologous BR. METHODS: Using the Nationwide Inpatient Sample database (2008 to 2012), data on BC and mastectomy rates, type of autologous BR, and sociodemographics were obtained and analyzed...

INTRODUCTION: Abdominal based breast reconstruction exists in a continuum from pedicled transverse rectus abdominis myocutaneous (TRAM) flap to deep inferior epigastric perforator (DIEP) free flap. DIEP flap has the advantage of complete rectus abdominis sparing during harvest, thus decreasing donor site morbidity. Aim of this study is to determine whether the surgical advantages of the DIEP flap impact postoperative outcomes versus the free TRAM flap (fTRAM). METHODS: We reviewed the Nationwide Inpatient Sample database (2010-2011) for all cases of DIEP and fTRAM breast reconstruction...

A 46-year-old female presented with an inflamed and painful umbilicus. Past medical history included breast cancer, followed by metastatic sternal cancer two years after the initial breast cancer diagnosis.The painful umbilicus was confirmed metastasis from a primary breast cancer she had treated eleven years previously.Metastases to the umbilicus are rare, and are usually gastrointestinal in origin. To our knowledge this is the first report of a metastasis from any primary cancer to the umbilicus after transverse rectus abdominis myocutaneous flap (TRAM)...

BACKGROUND: Tissue transfer, such as use of the transverse rectus abdominis myocutaneous (TRAM) or deep inferior epigastric artery perforator (DIEP) free flaps, is considered a standard method. However, outcomes may vary among inset methods. Here we compared the aesthetic outcomes of breast reconstructions using vertical and horizontal flap inset methods. METHODS: We, respectively, reviewed 274 patients who underwent unilateral post-mastectomy breast reconstruction using TRAM or DIEP free flaps between April 2006 and December 2013...

Electrogenesis in mesenchymal stromal cells (MSCs) remains poorly understood. Little is known about ion channels active in resting MSCs and activated upon MSC stimulation, particularly, by agonists mobilizing Ca(2+) in the MSC cytoplasm. A variety of Ca(2+)-gated ion channels may couple Ca(2+) signals to polarization of the plasma membrane. Here, we studied MSCs from the human adipose tissue and found that in cells responsive to ATP and adenosine with Ca(2+) transients or exhibiting spontaneous Ca(2+) oscillations, Ca(2+) bursts were associated with hyperpolarization mediated by Ca(2+)-gated K(+) channels...

The study and application of human pluripotent stem cells (hPSCs) will be enhanced by the availability of well-characterised monoclonal antibodies (mAbs) detecting cell-surface epitopes. Here we report generation of seven new mAbs that detect cell surface proteins present on live and fixed human ES cells (hESCs) and human iPS cells (hiPSCs), confirming our previous prediction that these proteins were present on the cell surface of hPSCs. The mAbs all show a high correlation with POU5F1 (OCT4) expression and other hPSC surface markers (TRA-160 and SSEA-4) in hPSC cultures and detect rare OCT4 positive cells in differentiated cell cultures...

Members of the cytochrome P450 1A family metabolize many procarcinogens such as polycyclic aromatic hydrocarbons and heterocyclic amines. Inactivation of these enzymes is prerequisite for cancer prevention and treatment in certain cases. Mechanism-based inhibition (time and co-factor dependent) is an effective method for the inactivation of these enzymes. Our recent study on emodin analogs revealed an anthraquinone with ortho-methylarylamine moiety that exhibited time-dependent inhibition of P450 enzymes 1A1 and 1A2...

INTRODUCTION: Tramway has become a serious urban noise source in densely populated areas. The disturbance from squealing noise is significant. Curve squeal is the very loud, tonal noise emitted by tram operation in tight radius curves. Studies had reported a relationship between noise levels and health effects, such as annoyance, sleep disturbance, and elevated systolic and diastolic blood pressure. MATERIALS AND METHODS: This study aimed to analyze the wheel squeal noise along the tramway line in Košice, Slovakia, review the effects on human health, and discuss its inclusion in the design method...

HLA-DPB1 permissive matching based on T cell epitope (TCE) groups should be considered when selecting among equally matched HLA-A, -B, -C, -DRB1 unrelated hematopoietic stem cell donors to improve patient survival. Previous studies have defined 3 TCE groups based on functional assays of alloreactivity. Combinations of donor and recipient DPB1 alleles with low immunogenic potential identify permissive donors, who provide no increased risk of mortality compared with DPB1-matched donors. To determine the likelihood of identifying a DPB1 permissive-matched (includes both allele-matched and DPB1-permissive mismatched) unrelated donor for patients with high-resolution matches at 10/10 HLA-A, -B,- C, -DRB1, and -DQB1 in the Be The Match Registry, preliminary search requests from United States' transplant centers for 595 DPB1-typed patients were evaluated for existence of a DPB1 permissive-matched donor, identified either among already typed donors or by prospective DPB1 typing...

Here, we report proteomic analyses of 129 human cortical tissues to define changes associated with the asymptomatic and symptomatic stages of Alzheimer's disease (AD). Network analysis revealed 16 modules of co-expressed proteins, 10 of which correlated with AD phenotypes. A subset of modules overlapped with RNA co-expression networks, including those associated with neurons and astroglial cell types, showing altered expression in AD, even in the asymptomatic stages. Overlap of RNA and protein networks was otherwise modest, with many modules specific to the proteome, including those linked to microtubule function and inflammation...
