Systemic diffuse large B-cell lymphoma (DLBCL) is a potentially curable disease using current regimen of immunochemotherapy. Central nervous system (CNS) relapse is a complication that occurs in approximately 5% of DLBCL patients and is associated with a high fatality rate. Early identification of molecular markers for CNS involvement may serve for the highly needed accurate stratification of patients into risk groups regarding CNS relapse. MicroRNAs (miRNAs) are small non-coding RNA molecules that regulate gene expression at the post-transcriptional level and are known to be involved in DLBCL pathophysiology...

Dae-Kyo Jeong, Jung-Hwa Wui, Dongwoo Kim
In this paper, we model and investigate the random access (RA) performance of sensor nodes (SN) in a wireless sensor network (WSN). In the WSN, a central head sensor (HS) collects the information from distributed SNs, and jammers disturb the information transmission primarily by generating interference. In this paper, two jamming attacks are considered: power and code jamming. Power jammers (if they are friendly jammers) generate noises and, as a result, degrade the quality of the signal from SNs. Power jamming is equally harmful to all the SNs that are accessing HS and simply induces denial of service (DoS) without any need to hack HS or SNs...

With the widespread use of electric machines, there is a growing need to extract information from the machines to improve their control systems and maintenance management. The present work shows the development of an embedded system to perform the monitoring of the rotor physical variables of a squirrel cage induction motor. The system is comprised of: a circuit to acquire desirable rotor variable(s) and value(s) that send it to the computer; a rectifier and power storage circuit that converts an alternating current in a continuous current but also stores energy for a certain amount of time to wait for the motor's shutdown; and a magnetic generator that harvests energy from the rotating field to power the circuits mentioned above...

Latina women in the United States (U.S.) are disproportionately affected by obesity and are more likely to begin pregnancy overweight and gain excessive weight during pregnancy. The prenatal care period represents a window of opportunity for women to access the healthcare system and receive preventive services, education, nutritional support, and other social services to improve pregnancy outcomes. Excessive gestational weight gain (GWG) has numerous negative short- and long-term consequences for both the mother and newborn...

Planning and management needs up-to-date, easily-obtainable and accurate information on the spatial and social aspects of visitor behaviour in order to balance human use and impacts, and protection of natural resources in public parks. We used a web-based public participation GIS (PPGIS) approach to gather citizen data on visitor behaviour in Helsinki's Central Park in order to aid collaborative spatial decision-making. The study combined smartphone GPS tracking, route drawing and a questionnaire to examine differences between user groups in their use of formal trails, off-trail behaviour and the motivations that affect it...

BACKGROUND: The past decade has seen over a four-fold increase in deaths from opioid overdose in the United States. To address this growing epidemic, many localities initiated policies to expand access to naloxone (a drug that reverses the effects of opioids); however, little is known how naloxone access affects opioid use behaviours. METHODS: The present qualitative study used semi-structured, in-depth interviews with inpatients at a substance use treatment centre...

BACKGROUND: An increase in heroin seizures in East Africa may signal wider local consumption of illicit drugs. Most information about drug use in Tanzania is from the economic capital, Dar es Salaam, and well-travelled Zanzibar. More data are needed on the extent, trends, and characteristics of illicit drug use in the vast coast and interior of the country. METHODS: The study was a rapid assessment, triangulating data from in-depth interviews of primary key informants (people who use drugs [PWUD]), secondary informants (police, community members, service providers), and ethnographic mapping of hotspots in 12 regions of Tanzania...

Seabirds are often cited as sentinels of the marine environment, but are rarely used in traditional ocean and coastal contaminant monitoring. Four classes of persistent organic pollutants (POPs, n=68) and three trace elements (mercury, selenium, and arsenic) were measured in the eggs of California least terns (Sterna antillarum browni), caspian terns (Hydroprogne caspia), double-crested cormorants (Phalacrocorax auritus), and western gulls (Larus occidentalis) that nest in the Southern California Bight. Building on a periodic five year regional monitoring program, we measured contaminant exposure and assessed the utility of seabirds as regional contaminant biomonitors...

This paper is based upon findings from the qualitative element of a mixed-methods study on the response of Black women aged 25-50 to a public health intervention related to breast cancer. The focus groups were conducted in the London Borough of Hackney, UK between 2013 and 2016, and were part of an evaluation of the effectiveness of a breast awareness DVD. While the content of the DVD was generally well-received by the participants, the focus group discussions revealed a complex and, at times, contradictory response to the women's construction as an 'at risk' community...

Mental files theory explains why children pass many perspective taking tasks like the false belief test around age 4 (Perner & Leahy, 2016). It also explains why older children struggle to understand that beliefs about an object depend on how one is acquainted with it (intensionality or aspectuality). If Heinz looks at an object that is both a die and an eraser, but cannot tell by looking that it is an eraser, he will not reach for it if he needs an eraser. Four- to 6-year olds find this difficult (Apperly & Robinson, 1998)...

Cardiopulmonary bypass surgery is associated with a high incidence of neurological complications, including stroke, delirium and cognitive impairment. The development of strategies to reduce the incidence of such neurological events has been hampered by the lack of a clear understanding of their pathophysiology. Cerebral autoregulation (CA), which describes the ability of the brain to maintain a stable cerebral blood flow over a wide range of cerebral perfusion pressures despite changes in blood pressure, is known to be impaired in various neurological disorders...

Vernal ponds, also referred to as vernal pools, provide critical ecosystem services and habitat for a variety of threatened and endangered species. However, they are vulnerable parts of the landscapes that are often poorly understood and understudied. Land use and management practices, as well as climate change are thought to be a contribution to the global amphibian decline. However, more research is needed to understand the extent of these impacts. Here, we present methodology for characterizing a vernal pond's morphology and detail a monitoring station that can be used to collect water quantity and quality data over the duration of a vernal pond's hydroperiod...

Cinnamaldehyde is a major constituent of cinnamon essential oils produced by aromatic cinnamon plants. This compound has been reported to exhibit antimicrobial properties in vitro in laboratory media and in animal feeds and human foods contaminated with disease-causing bacteria including Bacillus cereus, Campylobacter jejuni, Clostridium perfringens, Escherichia coli, Listeria monocytogenes, and Salmonella enterica. This integrated review surveys and interprets our current knowledge of the chemistry, analysis, safety, mechanism of action, and antibiotic activities of cinnamaldehyde in food animal (cattle, lambs, calves, pigs, poultry) diets and in widely consumed liquid (apple, carrot, tomato, and watermelon juices, milk) and solid foods...

Absorption, distribution, metabolism and excretion (ADME) of nanomaterials (NMs) or nanomedicines (NMs), are fundamental biological processes that dominate their nanomedical functions or nanotoxicities. Mostly, NMs exist in biological systems as a form of nanoparticles (NPs). However, to determine the composition, spatial distribution, and states of existence of NMs/NPs in vivo, upon entry into the body, as well as to monitor the dynamic changes of these information over time remain a challenge for the current analytical methodology due to their limited efficiently in characterizing interactions between these complex(nano)-complex(bio) systems...

Various ionization methods in mass spectrometry (MS) are available for the analysis of analytes with different properties. Nonetheless, using a single ionization method to analyze mixtures containing analytes with different polarities and volatiles in different phases at atmospheric pressure remains a challenge. Exploring an ionization method that can ionize small organics and large biomolecules with different properties for MS analysis is advantageous. Carbon fiber ionization mass spectrometry (CFI-MS) that uses a carbon fiber bundle as the ion source is useful for the analysis of small organics with low polarities...

Jing Lin, Zhen Cheng, Qi Qian
As the population ages, greater numbers of elderly patients will present with kidney diseases. Many kidney diseases, such as IgA nephropathy, will require kidney biopsy for diagnostic confirmation, treatment guidance and prognostication. In this paper, we review the current and expected future healthcare landscape with a focus on the ageing population, pros and cons of kidney biopsy in elderly patients, as well as treatment strategies and precautions. We also review the available data on IgA nephropathy in the elderly, including its occurrence rate based on the kidney biopsy, clinicohistopathological features, differentiation with IgA-dominant postinfectious glomerulonephritis, treatment options and outcome prediction...
