Should you use steroids to treat infectious mononucleosis?
(Family Physicians Inquiries Network, 2008)
Studies of steroids to treat infectious mononucleosis have found no significant effect on the clinical course of the illness at 1 to 3 months (strength of recommendation [SOR]: B, 1 randomized controlled trial [RCT] and 1 ...
Should you evaluate for CAD in seniors with premature ventricular contractions?
(Family Physicians Inquiries Network, 2008)
Current guidelines suggest evaluating patients with premature ventricular contractions (PVCs) and associated risk factors for underlying coronary artery disease (strength of recommendation [SOR]: C, expert opinion).
What could be behind your elderly patient's subjective memory complaints?
(Family Physicians Inquiries Network, 2008)
Depression, anxiety, and dementia, as well as older age, female gender, lower education level, and decreased physical activity, have all been associated with memory loss reported by patients or family members (strength of ...
What is the best test for peripheral vascular disease?
(Family Physicians Inquiries Network, 2008)
An ankle-brachial index is best for evaluating patients with symptoms of claudication (strength of recommendation [SOR]: B, multiple cohort studies). That said, duplex ultrasonography or magnetic resonance angiography may ...
What is the clinical workup for failure to thrive?
(Family Physicians Inquiries Network, 2008)
The clinical evaluation of failure to thrive (FTT) includes a thorough history and physical examination; observation of parent-child interactions; observation and documentation of the child's feeding patterns; and a home ...
What are the causes of elevated TSH in a newborn?
(Family Physicians Inquiries Network, 2008)
Congenital hypothyroidism is a critical cause of elevated thyroid-stimulating hormone (TSH) in newborns; evaluate all neonates with an elevated TSH for congenital hypothyroidism (strength of recommendation [SOR]: A). Other ...
Is there a well-tested tool to detect drug-seeking behaviors in chronic pain patients?
(Family Physicians Inquiries Network, 2008)
There is no well-tested, easily administered screening tool to detect drug-seeking behaviors in primary care patients taking long-term opioids or being considered for such therapy (strength of recommendation [SOR]: C, ...
What is the differential diagnosis of chronic leg edema in primary care?
(Family Physicians Inquiries Network, 2008)
The differential diagnosis, in descending order, includes: elevated pulmonary artery pressure (often due to obstructive sleep apnea), congestive heart failure, idiopathic causes, venous insufficiency, use of nonsteroidal ...
What drugs are best for bipolar depression?
(Family Physicians Inquiries Network, 2008)
Antidepressants, including tricyclics and selective serotonin reuptake inhibitors (SSRIs), are useful adjuncts in short-term treatment of bipolar depression and have low rates of inducing mania (strength of recommendation ...
Polyfluorene as a model system for space-charge-limited conduction
(arXiv, 2008)
Ethyl-hexyl substituted polyfluorene (PF) with its high level of molecular disorder can be described very well by one-carrier space-charge-limited conduction for a discrete set of trap levels with energy $\sim$ 0.5 eV above ...
Astrodynamical Space Test of Relativity using Optical Devices I (ASTROD I) - A class-M fundamental physics mission proposal for Cosmic Vision 2015-2025
(arXiv, 2008)
ASTROD I is a planned interplanetary space mission with multiple goals. The primary aims are: to test General Relativity with an improvement in sensitivity of over 3 orders of magnitude, improving our understanding of ...
Anti-chaperone [eszett]A3/A1102-117 peptide interacting sites in human aB-crystallin
(Molecular Vision, 2008)
Purpose: Our previous work identified 23 low molecular weight (<3.5 kDa) crystallin peptides in the urea-soluble fractions of normal young, normal aged, and aged cataract human lenses. We found that one of these crystallin ...
Maximal efficiency of coupling between ATP hydrolysis and translocation of polypeptides mediated by secB requires two protomers of secA
(American Society for Microbiology, 2008)
SecA is the ATPase that provides energy for translocation of precursor polypeptides through the SecYEG translocon in Escherichia coli during protein export. We have previously shown that when SecA receives the precursor ...
Is training patients in self-examination an effective way to screen for melanoma?
(Family Physicians Inquiries Network, 2008)
No studies demonstrate that training patients to examine their skin decreases mortality from melanoma in the general population. Nor is there any evidence to suggest that teaching patients to monitor their skin for suspicious ...
Significance of interactions of low molecular weight crystallin fragments in lens aging and cataract formation
(The American Society for Biochemistry and Molecular Biology, 2008)
Analysis of aged and cataract lenses shows the presence of increased amounts of crystallin fragments in the high molecular weight aggregates of water-soluble and water-insoluble fractions. However, the significance of ...
The 21 micron and 30 micron circumstellar dust features in evolved C-rich objects
(2008)
The 21micron and 30micron bands are the strongest dust emission features detected in evolved low- and intermediate-mass C-rich stars (i.e. asymptotic giant branch [AGB] stars, proto-planetary nebulae [PPN], and planetary ...
VLT / Infrared Integral Field Spectrometer Observations of Molecular Hydrogen Lines in the Knots in the Planetary Nebula NGC 7293 (the Helix Nebula)
(2008)
Knots are commonly found in nearby planetary nebulae (PNe) and star forming regions. Within PNe, knots are often found to be associated with the brightest parts of the nebulae and understanding the physics involved in knots ...
Experimental evaluation of apparent tissue surface tension based on the exact solution of the Laplace equation
(IOP, 2008)
The notion of apparent tissue surface tension offered a systematic way to interpret
certain morphogenetic processes in early development. It also allowed deducing quantitative information on cellular and molecular parameters ...
Biotechnology Adoption Over Time In the Presence of Non-Pecuniary Characteristics that Directly Affect Utility : A Derived Demand Approach
(AgBioForum, 2008)
Generally, new production technologies are adopted because they will increase profits, mostly due to lower production costs ceteris paribus. In the case of the first-generation crop biotechnologies, however, additional ...
