Purification of cell type-specific RNAs remains a significant challenge. One solution involves biosynthetic tagging of target RNAs. RNA tagging via incorporation of 4-thiouracil (TU) in cells expressing transgenic uracil phosphoribosyltransferase (UPRT), a method known as TU-tagging, has been used in multiple systems but can have limited specificity due to endogenous pathways of TU incorporation. Here, we describe an alternative method that requires the activity of two enzymes: cytosine deaminase (CD) and UPRT...

Chronic inflammation may be a risk factor for breast cancer development and progression, yet which inflammatory biomarkers and pathways are relevant is unknown. The study included 27,071 Women's Health Study participants (mean, 54.5 years old) free of cancer and cardiovascular disease at enrollment (1992 to 1995) with baseline measures of four inflammatory biomarkers: high sensitivity C-reactive protein (hsCRP), fibrinogen, N-acetyl side-chains of acute phase proteins (GlycA), and soluble intercellular adhesion molecule-1 (sICAM-1)...

BACKGROUND: Complete tumour response (pCR) to neo-adjuvant chemo-radiotherapy for rectal cancer is associated with a reduction in local recurrence and improved disease-free and overall survival, but is achieved in only 20-30% of patients. Drug repurposing for anti-cancer treatments is gaining momentum, but the potential of such drugs as adjuncts, to increase tumour response to chemo-radiotherapy in rectal cancer, is only just beginning to be recognised. METHODS: A systematic literature search was conducted and all studies investigating the use of drugs to enhance response to neo-adjuvant radiation in rectal cancer were included...

UV-B ray has been addressed to trigger common metabolic responses on marine microalgae, however, the upstream events responsible for these changes in marine microalgae are poorly understood. In the present study, a species of marine green microalgae Dunaliella salina was exposed to a series of enhanced UV-B radiation ranging from 0.25 to 1.00 KJ·m(-2) per day. The role of ROS and calcium signaling in the D. salina responses to UV-B was discussed. Results showed that enhanced UV-B radiation markedly decreased the cell density in a dose-dependent manner, but the contents of protein and glycerol that were essential for cell growth increased...

Between 2009 and 2012 there were 26 epilepsy-related deaths in the UK of women who were pregnant or in the first post-partum year. The number of pregnancy-related deaths in women with epilepsy (WWE) has been increasing. Expert assessment suggests that most epilepsy-related deaths in pregnancy were preventable and attributable to poor seizure control. While prevention of seizures during pregnancy is important, a balance must be struck between seizure control and the teratogenic potential of antiepileptic drugs (AEDs)...

OBJECTIVE: Care coordinators may help manage care for children with chronic illness. Their role in pediatric epilepsy care is understudied. We aimed to qualitatively describe the content of a care coordination intervention for children with epilepsy. METHODS: We conducted nine semi-structured interviews and one focus group with care coordinators at a pediatric accountable care organization (ACO) in Ohio. The care coordinators used a modified version of a published care coordination checklist for children with epilepsy (Patel AD, 2014)...

C5BL/6 female mice receiving dextran sodium sulfate in their drinking water develop an acute inflammatory colitis within 7d, with weight loss, histopathologic signs of inflammation, and colonic expression of inflammatory cytokines. In previous studies we have reported that increased inflammatory cytokine expression in aged mice can be attenuated by oral gavage of a crude fetal extract containing glutathione (GSH), MPLA and fetal hemoglobin, or more specifically by injection of a combination of these purified reagents...

Dual leucine zipper kinase (DLK) has been implicated in cell death signaling secondary to axonal damage in retinal ganglion cells (RGCs) and other neurons. To better understand the pathway through which DLK acts, we developed enhanced functional genomic screens in primary RGCs, including use of arrayed, whole-genome, small interfering RNA libraries. Explaining why DLK inhibition is only partially protective, we identify leucine zipper kinase (LZK) as cooperating with DLK to activate downstream signaling and cell death in RGCs, including in a mouse model of optic nerve injury, and show that the same pathway is active in human stem cell-derived RGCs...

Assessing physicians' experiences in HPV vaccine recommendation and delivery to adolescent boys is essential to providing an understanding of the issues of vaccine acceptance and an insight for policymakers to enhance HPV vaccinations among adolescent boys. Between January and April 2014 a mail survey was conducted using physicians in Malaysia known to provide either one or both HPV vaccine (Gardasil and Cervarix) immunisation services. A total of 357 completed questionnaires were received (response rate 22...

There are many tests of learning and memory; however, not all yield analogous results and thus are not interchangeable. This study examined the relationship between the California Verbal Learning Test-Second Edition (CVLT-II) and the Buschke Selective Reminding Test (SRT) in a stroke population. Data from stroke inpatients (N = 102) referred for rehabilitation were collected from medical records. Both tests were administered, as part of a larger neuropsychological assessment. Analyses were conducted on Z-scores from the List Total, Learning, and Long Delay Free Recall (LDFR) subscales of the two tests...

OBJECTIVE: Methylphenidate activates μ-opioid receptors, which are linked to euphoria. μ-Opioid antagonists, such as naltrexone, may attenuate the euphoric effects of stimulants, thereby minimizing their abuse potential. This study assessed whether the combination of naltrexone with methylphenidate is well-tolerated while preserving the clinical benefits of stimulants in subjects with attention-deficit/hyperactivity disorder (ADHD). METHODS: We conducted a 6-week, double-blind, placebo-controlled, randomized clinical trial of naltrexone in adults with DSM-IV ADHD receiving open treatment with a long-acting formulation of methylphenidate from January 2013 to July 2015...

The frontotemporal lobar degeneration (FTLD) protein progranulin (PGRN) is essential for proper lysosomal function. PGRN localizes in the lysosomal compartment within the cell. Prosaposin (PSAP), the precursor of lysosomal saposin activators (saposin A, B, C, D), physically interacts with PGRN. Previously we have shown that PGRN and PSAP facilitate each other's lysosomal trafficking. Here we report that the interaction between PSAP and PGRN requires the linker region of saposin B and C (BC linker). PSAP protein with the BC linker mutated fails to interact with PGRN and target PGRN to lysosomes in the biosynthetic and endocytic pathways...

Driving under the influence of drugs (DUID) is a worldwide problem. Several countries adopted DUID legislations which prove their deterrent effect and impact on road safety. However, use of new psychoactive substances (NPS) and prescription drugs is not known as the applied roadside screening tests are not yet adapted for these compounds. In this study, 558 blood samples obtained during roadside controls in Belgium (January to August 2015) after a positive Drugwipe 5S® test and 199 oral fluid (OF) samples obtained from negatively screened test pads were analyzed...

Mutations of CYP21A2 variably decrease 21-hydroxylase activity and result in a spectrum of disease expressions in patients with congenital adrenal hyperplasia (CAH). We examined the association between CYP21A2 mutations and virilization (Prader score) in females with CAH. The study population included 187 CAH females with fully characterized CYP21A2 mutations. One hundred fifty-eight patients were sorted into groups by expected enzyme activity (percent of normal activity) of the less severely affected allele: (A) null, 0%; (B) I2G, 1%; (C) I172N, 2%; and (D) V281L, >2%...

Under a traditional paradigm, only those with the expected background knowledge consume academic literature. The lay press, as well as government and non-government agencies, play a complementary role of extracting findings of high interest or importance and translating them for general viewing. The need for accurate reporting and public advising is paramount when attempting to tackle epidemic outbreaks through behavior change. Yet, public trust in media outlets is at a historic low. The Crisis and Emergency Risk Communication (CERC) model for media reporting on public health emergencies was established in 2005 and has subsequently been used to analyze media reporting on outbreaks of influenza and measles as well as smoking habits and medication compliance...
