PurposePompe disease results from lysosomal acid α-glucosidase (GAA) deficiency and its associated glycogen accumulation and muscle damage. Alglucosidase alfa (recombinant human GAA (rhGAA)) received approval in 2006 as a treatment for Pompe disease at the 160 L production scale. In 2010, larger-scale rhGAA was approved for patients up to 8 years old without cardiomyopathy. NCT01526785 evaluated 4,000 L rhGAA efficacy/safety in US infantile- or late-onset Pompe disease (IOPD, LOPD) patients up to 1 year old transitioned from 160 L rhGAA...

The impact of chronic cadmium exposure and slow accumulation on the occurrence and development of diabetes is controversial for human populations. Islets of Langerhans play a prominent role in the etiology of the disease, including by their ability to secrete insulin. Conversion of glucose increase into insulin secretion involves mitochondria. A rat model of pancreatic β-cells was exposed to largely sub-lethal levels of cadmium cations applied for the longest possible time. Cadmium entered cells at concentrations far below those inducing cell death and accumulated by factors reaching several hundred folds the basal level...

BACKGROUND: Malnutrition is a frequent medical problem of cancer patients that negatively impacts their quality of life. OBJECTIVE: To analyze and respond to different issues related to the nutritional management of cancer patients in the clinical setting. METHODS: A multidisciplinary group of experts in Medical Oncology, Pharmacy, and Nutrition developed a list of topics related to the nutritional status of cancer patients, which were grouped into three blocks: Nutritional support; Parenteral nutrition (PN); and Home PN (HPN) in cancer patients...

BACKGROUND: Malnutrition is particularly prevalent among intensive care unit (ICU) patients, being associated with poor clinical results. Enteral nutrition (EN) offers multiple benefits on critically ill patients and its monitoring was established by the Spanish Society of Critical Care (SEMICYUC) as a clinical quality indicator (CQI; EN patients correctly monitorized / all EN patients, as %). However, no results have been published on its regulated monitoring. OBJECTIVES: Assessing CQI's compliance, identifying difficulties and possibilities for its use...

Nanoparticles in biological systems encounter lipid-bilayer membranes as barriers. They interact with plasma membranes, membranous organelles, such as the endoplasmic reticulum and the Golgi apparatus, the nucleus, and intracellular and extracellular vesicles, such as autophagosomes, lysosomes, and exosomes. Extracellular vesicles have recently attracted particular attention, as they are involved in the transmission of biological signals and as regulators for biological processes. For example, exosomes, small vesicles containing proteins, mRNA, and miRNA, that are released by cells into the extracellular environment, have been suggested to participate in tumor metastasis...

Despite promising in-vitro evidence for effective glioblastoma treatment, most drugs are hindered from entering the central nervous system due to the presence of the blood-brain barrier (BBB). Thus, successful modification of drug delivery and novel therapeutic strategies are needed to overcome this obstacle. Extracellular vesicles (EVs), cell-derived membrane-encapsulated structures with diameters ranging from 50-1000 nm, have been explored as drug delivery system to deliver their cargo to the brain tissue...

This report presents an outbreak of monophasic Salmonella enteric serovar Typhimurium fagotipe 4, 5, 12: i:-, in a motorcycle concentration in Valladolid. Information was collected to one hundred and twelve affected from seven Spanish Autonomous Communities. The epidemiological investigation associated the outbreak with the consumption of roast pork with sauce sandwiches sold at a street market in that event.

BACKGROUND: Use of the electronic health record (EHR) is widespread in academic medical centers, and hands-on EHR experience in medical school is essential for new residents to be able to meaningfully contribute to patient care. As system-specific EHR training is not portable across institutions-even when the same EHR platform is used-students rotating across health systems are often required to spend time away from clinical training to complete each system's, often duplicative, EHR training regardless of their competency within the EHR...

Cells that undergo checkpoint adaptation arrest at and then abrogate the G2/M cell cycle checkpoint to enter mitosis with damaged DNA. Cells surviving this process frequently contain micronuclei, which can lead to genomic change and chromothripsis. In this chapter we describe how to induce checkpoint adaptation and detect it by time-lapse video and immunofluorescence microscopy and how to isolate cells undergoing checkpoint adaptation from a total cell population.

Blood-brain barrier (BBB) permeability of a compound determines whether the compound can effectively enter the brain. It is an essential property which must be accounted for in drug discovery with a target in the brain. Several computational methods have been used to predict the BBB permeability. In particular, support vector machine (SVM), which is a kernel-based machine learning method, has been used popularly in this field. For SVM training and prediction, the compounds are characterized by molecular descriptors...

A "precocious" cleavage furrow develops and ingresses during early prometaphase in Mesostoma ehrenbergii spermatocytes (Forer and Pickett-Heaps Eur J Cell Biol 89:607-618, 2010). In response to chromosome movements which regularly occur during prometaphase and that alter the balance of chromosomes in the two half-spindles, the precocious furrow shifts its position along the cell, moving 2-3 μm towards the half cell with fewer chromosomes (Ferraro-Gideon et al. Cell Biol Int 37:892-898, 2013). This process continues until proper segregation is achieved and the cell enters anaphase with the cleavage furrow again in the middle of the cell...

Background: The issue of menstrual hygiene is inadequately acknowledged in our nation. The use of sanitary pads and washing the genital area are essential practices for good menstrual hygiene. Poor menstrual hygiene may lead to itching or rashes in the perineal region, bad odor, and sometimes, major complications such as pelvic inflammatory disease and toxic shock syndrome. Therefore, the objective of this study was to assess the knowledge and practice of menstrual hygiene among reproductive age group women...

Aim: The aims of this study were to investigate antibiotic resistance pattern and molecular characterization of Salmonella Infantis strains, isolated from human sources in Tehran hospitals from 2008 to 2010. Background: Infection caused by Salmonella is one of the major public health problems. Despite the clinical importance of Salmonella enteric subsp. enteric serovar Infantis in humans, there is no information available about the common clones of Salmonella Infantis in clinical isolates in Iran...

We report a case of a 59-year-old woman who was diagnosed with gastric and small intestinal anisakiasis, which was successfully treated with endoscopic extraction and Gastrografin therapy. She was admitted to our hospital with epigastric pain and vomiting one day after eating raw fish. She exhibited tenderness in the epigastrium without obvious rebound tenderness or guarding. Computed tomography (CT) demonstrated segmental edema of the intestinal wall with proximal dilatation and a small number of ascites. Because enteric anisakiasis was suspected based on the patient's history of recent raw fish consumption and abdominal CT, we performed gastroscopy and confirmed that nine Anisakis larvae were attached to the gastric mucosa...

The Human T-cell leukemia virus type 1 (HTLV-1)-encoded accessory protein p8 is cleaved from the precursor protein p12 encoded by the HTLV-1 open reading frame I. Both p12 and p8 are thought to contribute to efficient viral persistence. Mechanistically, p8 induces T-cell conjugates and cellular conduits. The latter are considered to facilitate transfer of p8 to target cells and virus transmission. Transfer of p8 between p8-expressing T-cells and recipient cells has been analyzed by immunofluorescence and live imaging...

Gastrointestinal (GI) motility disorders such as irritable bowel syndrome (IBS) can occur when coordinated smooth muscle contractility is disrupted. Potassium (K+ ) channels regulate GI smooth muscle tone and are key to GI tract relaxation, but their molecular and functional phenotypes are poorly described. Here we define the expression and functional roles of mechano-gated K2P channels in mouse ileum and colon. Expression and distribution of the K2P channel family were investigated using quantitative RT-PCR (qPCR), immunohistochemistry and confocal microscopy...
