INTRODUCTION: Primary apocrine sweat gland carcinoma (PASGC) is an extremely rare neoplasia whose management and treatment are still evolving. The only curative therapy is wide local excision. Many patients have metastasis at the time of the diagnosis, mainly because this neoplasm has been misdiagnosed as some benign skin lesions. PRESENTATION OF CASE: We herein report a case of a 72-year-old-man with PASGC affecting the axilla and regional lymph nodes that underwent surgical resection and lymphadenectomy at our Institution...

Efficient delivery of anti-dandruff (AD) actives into the scalp follicular infundibulum as well as onto the scalp surface is critical for the efficacy of AD shampoos. A method involving scalp cyanoacrylate (CA) biopsy sampling, a tailor made cutting device, ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) analysis, scanning electron microscopy (SEM) measurement and Raman imaging has been developed for the measurement of delivery of zinc pyrithione (ZPT) and climbazole (CBZ) from an AD shampoo into the scalp follicular infundibulum...

During the last decades, important advances in therapeutic options have led to increased survival rates in cancer patients; however, cancer treatments are associated with several potential adverse effects including infertility in those diagnosed during their reproductive years. A proper discussion about fertility preservation options before the use of therapies with potential gonadotoxicity (i.e. oncofertility counseling) is standard of care and should be offered to all patients of childbearing age. Temporary ovarian suppression with LH-RH analogs, oocyte and embryo cryopreservation are standard strategies for fertility preservation in female cancer patients...

Recent evidence suggests that dysregulation of microRNAs are associated with the development of multiple malignancies.miR-186 has been reported as a critical cancer regulator in several types of cancers. However, its functional significance and molecular mechanism underlying renal cell carcinoma (RCC) remains unknown. In this study, our results showed that miR-186 expression was dramatically downregulated in RCC tissues and cell lines compared to that in adjacent normal tissues and cell lines. Overexpression of miR-186 significantly inhibited cell growth, colony formation, cell invasion, caused cell cycle arrest at G0/G1 phase, and induced cell apoptosis as detected by MTT, colony formation, Transwell assay, and flow cytometry assays in RCC cells...

Repetitive transcranial magnetic stimulation (rTMS) is a novel physiological therapy that has been adopted to clinically treat psychiatric disorders. Our previous study indicated the potential therapeutic effect of rTMS on posttraumatic stress disorder (PTSD). However, the exact molecular mechanism is elusive. Currently, using the single prolonged stress (SPS) rat model for PTSD, we investigated the glutamatergic transmission and neural plasticity changes in the anterior cingulate cortex (ACC) after SPS induction and explored the protective effects and mechanism of rTMS treatment...

Functional Magnetic Resonance Imaging (fMRI) is at present one of the most used methodologies for functional brain exploration, both in clinical and research settings. fMRI can noninvasively measure neural activity by using specific experimental paradigms. Often, these paradigms require the stimulation of the subject to perform sensorimotor tasks: in the past, the stimuli have been administered manually for investigating fundamental aspects of tactile perception and somatosensory processing. Nowadays, the use of mechatronic devices to stimulate the subject during fMRI studies is growing, also to assure reproducibility, control, and monitoring of task performances...

Invariant natural killer T (iNKT) cells play important roles in antimicrobial defense and immune-regulation. We have previously shown that iNKT cells express certain toll-like receptors (TLR), and that TLR co-stimulation of iNKT cells in the presence of suboptimal concentrations of T cell receptor (TCR) agonists enhances cellular activation. In the present study, we investigated the regulatory effects of CpG oligonucleotides in mouse primary hepatic and splenic iNKT cells and in DN32.D3 iNKT cells. We show that CpG treatment of iNKT cells in the presence of higher concentrations of TCR agonists (α-GalCer or anti-CD3 mAb) results in the up-regulation of TLR9 in iNKT cells with a concurrent reduction in their cellular activation, as assessed by their production of IL-2, IL-4 and IFN-γ compared with controls...

To determine whether IL-21 receptor signaling plays a significant role in promoting Tfh cell-mediated cardiac injury in viral myocarditis (VMC), we compared IL-21R-deficient mice for some parameters of VMC. Balb/c and IL-21R(-/-) mice were infected with CVB3. Frequencies of splenic Tfh cells were determined by flow cytometric analysis, and productions of anti-adenine nucleotide translocator (ANT) autoantibodies were detected by enzyme-linked immunosorbent assay. To determine the effects of IL-21R signal on the proliferation of B cells, lymphocytes from spleens of the IL-21R(-/-) and Balb/c mice infected by CVB3 were tagged with carboxyfluorescein succinimidyl ester (CFSE) and then were stimulated with lipopolysaccharides plus IL-21 or anti-IL-21 neutralizing antibody for 3 days...

The term gut-liver axis is used to highlight the close anatomical and functional relationship between the intestine and the liver. The intestine has a highly specialized epithelial membrane which regulates transport across the mucosa. Due to dysbiosis, impairment of the intestinal barrier and altered immunity status, bacterial products can reach the liver through the portal vein, where they are recognized by specific receptors, activate the immune system and lead to a proinflammatory response. Gut microbiota and bacterial translocation play an important role in the pathogenesis of chronic liver diseases, including alcoholic and non-alcoholic fatty liver disease, cirrhosis, and its complications, such as portal hypertension, spontaneous bacterial peritonitis and hepatic encephalopaty...

This qualitative social scientific study explores professional texts of healthcare ethics to understand the ways in which ethical professionalism in medicine and nursing are culturally constructed in Finland. Two books in ethics, published by Finnish national professional organizations-one for nurses and one for physicians-were analyzed with the method of critical discourse analysis. Codes of ethics for each profession were also scrutinized. Analysis of the texts sought to reveal what is taken for granted in the texts as well as to speculate what appeared to be relegated to the margins of the texts or left entirely invisible...

In Ghana, men who have sex with men (MSM) bear a high burden of HIV. Identifying factors that influence engagement in HIV care among HIV-infected Ghanaian MSM is critical to devising novel interventions and strengthening existing programs aimed at improving outcomes across the HIV care continuum. Consequently, we conducted an exploratory qualitative research study with 30 HIV-infected Ghanaian MSM between May 2015 and July 2015. Common barriers were fear of being seen in HIV-related health facility, financial difficulties, and health system challenges...

Deep learning techniques are being rapidly applied to medical imaging tasks-from organ and lesion segmentation to tissue and tumor classification. These techniques are becoming the leading algorithmic approaches to solve inherently difficult image processing tasks. Currently, the most critical requirement for successful implementation lies in the need for relatively large datasets that can be used for training the deep learning networks. Based on our initial studies of MR imaging examinations of the kidneys of patients affected by polycystic kidney disease (PKD), we have generated a unique database of imaging data and corresponding reference standard segmentations of polycystic kidneys...

There is a great need for the development of biomimetic human tissue models that allow elucidation of the pathophysiological conditions involved in disease initiation and progression. Conventional two-dimensional (2D) in vitro assays and animal models have been unable to fully recapitulate the critical characteristics of human physiology. Alternatively, three-dimensional (3D) tissue models are often developed in a low-throughput manner and lack crucial native-like architecture. The recent emergence of bioprinting technologies has enabled creating 3D tissue models that address the critical challenges of conventional in vitro assays through the development of custom bioinks and patient derived cells coupled with well-defined arrangements of biomaterials...

Effective, timely, and intentional policy efforts can significantly impact and improve the public's health and reduce racial and ethnic health disparities across the nation. Creating and implementing responsive policies at the state and county level is essential to supporting community efforts to improve health behaviors and health outcomes, particularly for communities of color who bear the brunt of disease risk and negative health outcomes. Using policy examples from the State of Maryland and Prince George's County, the largest and wealthiest predominately African-American county in the USA, this case study highlights the importance of state and county policy action when presented with opportunities to affect long-lasting, positive change...

DNA breaks can be induced by exogenous stimuli or by endogenous stress, but are also generated during recombination of V, D, and J genes (V(D)J recombination), immunoglobulin class switch recombination (CSR). Among various DNA breaks generated, DNA double strand break (DSB) is the most deleterious one. DNA damage response (DDR) is initiated when DSBs are detected, leading to DNA break repair by non-homologous end joining (NHEJ). The process is critically important for the generation of diversity for foreign antigens; and failure to exert DNA repair leads to immunodeficiency such as severe combined immunodeficiency and hyper-IgM syndrome...

Prolyl oligopeptidase (PREP) is conserved in many organisms across life. It is involved in numerous processes including brain function and neuropathology, that require more than its strict proteolytic role. It consists of a seven-bladed β-propeller juxtaposed to a catalytic α/β-hydrolase domain. The conformational dynamics of PREP involved in domain motions and the gating mechanism that allows substrate accessibility remain elusive. Here we used Hydrogen Deuterium eXchange Mass Spectrometry (HDX-MS) to derive the first near-residue resolution analysis of global PREP dynamics in the presence or absence of inhibitor bound in the active site...

Despite bovine pericardium (BP) being the primary biomaterial used in heart valve bioprostheses, recipient graft-specific immune responses remain a significant cause of graft failure. Consequently, tissue antigenicity remains the principal barrier for expanding use of such biomaterials in clinical practice. We hypothesize that our understanding of BP antigenicity can be improved by application of a combined affinity chromatography shotgun immunoproteomic approach to identify antigens that have previously been overlooked...
