Resistance exercise training for fibromyalgia (2013)

The evidence (rated as low quality) suggested that moderate- and moderate- to high-intensity resistance training improves multidimensional function, pain, tenderness, and muscle strength in women with fibromyalgia. The evidence (rated as low quality) also suggested that eight weeks of aerobic exercise was superior to moderate-intensity resistance training for improving pain in women with fibromyalgia. There was low-quality evidence that 12 weeks of low-intensity resistance training was superior to flexibility exercise training in women with fibromyalgia for improvements in pain and multidimensional function. There was low-quality evidence that women with fibromyalgia can safely perform moderate- to high-resistance training.
USML-1 microgravity glovebox experiment no. 1 Passive Accelerometer System (1995)

The passive accelerometer system (PAS) is a simple moving ball accelerometer capable of measuring the small magnitude steady relative acceleration that occurs in a low earth orbit spacecraft due to atmospheric drag and the earth's gravity gradient. The accelerometer can be used when the spacecraft continuously rotates during the orbit such that some line of reference in the craft always points along the vector connecting the earth's mass center with the spacecraft mass center. PAS was used successfully on the first United States Microgravity Laboratory (USML-1).

Antitumor activity of extracts and compounds from the rhizomes of <i>Veratrum dahuricum</i> (2008)

The antitumor activity of six extracts (ethanol extract, petroleum ether fraction, CHCl(3) fraction, ethyl acetate fraction, n-butanol fraction and total alkaloids) from the rhizomes of Veratrum dahuricum, and six compounds (veratramine (1), jervine (2), germine (3), veramitaline (4), veratrosine (5) and cyclopamine (6)) from the ethanol extract were investigated in vitro. The 12 samples exhibited cytotoxic activity against human tumor cell lines A549, PANC-1, SW1990 and NCI-H249. Among these samples, CHCl(3) fraction, the total alkaloids, compounds 1 and 6 showed higher inhibitory activity, compound 3 selectively exhibited significant cytotoxicity to SW1990 and NCI-H249.
Recent advances in sample preparation techniques to overcome difficulties encountered during quantitative analysis of small molecules from biofluids using LC-MS/MS (2014)

Liquid chromatography-mass spectrometry analysis of small molecules from biofluids requires sensitive and robust assays. Because of the very complex nature of many biological samples, efficient sample preparation protocols to remove unwanted components and to selectively extract the compounds of interest are an essential part of almost every bioanalytical workflow. This review describes the most common problems encountered during sample preparation, ways to optimize established sample preparation techniques and important recent developments to reduce or eliminate major interferents from biofluids.
Immunogenicity and virus-like particle formation of rotavirus capsid proteins produced in transgenic plants (2010)

The human pathogen, group A rotavirus, is the most prevalent cause of acute infantile and pediatric gastroenteritis worldwide, especially in developing countries. There is an urgent demand for safer, more effective and cheaper vaccines against rotavirus infection. Plant-derived antigens may provide an exclusive way to produce economical subunit vaccines. Virus-like particles, constituting viral capsid proteins without viral nucleic acids, are considered a far safer candidate compared with live attenuated viral vaccines. In this study, the rotavirus capsid proteins VP2, VP6 and VP7 were co-expressed in transgenic tobacco plants, and their expression levels, formation of rotavirus-like particles (RV VLPs) and immunogenicity were extensively studied. Quantitative real-time RT-PCR and Western blot analysis revealed that the expression level of vp6 was the highest while vp7 was expressed at the lowest levels. The RV VLPs were purified from transgenic tobacco plants and analyzed by electron microscopy and Western blot. Results indicated that the plant-derived VP2, VP6 and VP7 proteins self-assembled into 2/6 or 2/6/7 RV VLPs with a diameter of 60-80 nm. When orally delivered into mice with cholera toxin as an adjuvant, the total soluble protein extracted from transgenic tobacco plants induced rotavirus-specific antibodies comparable with those of attenuated rotavirus vaccines, while VP 2/6/7 induced higher serum IgG and fecal IgA titers compared with VP 2/6.
EFFECT OF MEDIUM PRESSURE AND LOW PRESSURE ULTRAVIOLET SYSTEMS ON THE INACTIVATION OF SELECTED BACTERIOPHAGES (2002)

EFFECT OF MEDIUM PRESSURE AND LOW PRESSURE ULTRAVIOLET SYSTEMS ON THE INACTIVATION OF SELECTED BACTERIOPHAGESFour bacteriophages, MS2, phi X-174, T4 and PRD-1 were used to assess the effectiveness of both the low pressure, low intensity (LPLI) and the medium pressure, high intensity (MPHI) ultraviolet light Collimated Beam Units (CBUs) on virus inactivation.

The V*-Diagram (2008)

The moving k nearest neighbor (M k NN) query finds the k nearest neighbors of a moving query point continuously. The high potential of reducing the query processing cost as well as the large spectrum of associated applications have attracted considerable attention to this query type from the database community. This paper presents an incremental safe-region-based technique for answering M k NN queries, called the V*-Diagram. In general, a safe region is a set of points where the query point can move without changing the query answer. Traditional safe-region approaches compute a safe region based on the data objects but independent of the query location. Our approach exploits the current knowledge of the query point and the search space in addition to the data objects. As a result, the V*-Diagram has much smaller IO and computation costs than existing methods. The experimental results show that the V*-Diagram outperforms the best existing technique by two orders of magnitude.
Plasma Brain Natriuretic Peptide as a Biochemical Marker for Atrioventricular Sequence in Patients with Pacemakers (1999)

We hypothesized that plasma brain natriuretic peptide, like plasma atrial natriuretic peptide, may reflect hemodynamic changes elicited by different cardiac pacing modes. The aim of this study was to investigate whether plasma brain natriuretic peptide could be influenced by different pacing modes or electrical stimulation. The subjects consisted of 164 patients with permanent pacemakers (52 VVI, 30 AAI, 82 DDD pacemakers) and unimpaired heart function. Patients with atrial fibrillation or spontaneous beats were excluded. Plasma atrial natriuretic peptide and brain natriuretic peptide levels were measured at a rate of 70 beats/min after 45 minutes in the supine position. Under ECG monitoring, the pacing mode was switched from DDD to VVI in 12 patients and from DDD to AAI in 4 patients with a dual chamber pacemaker. Plasma atrial natriuretic peptide and brain natriuretic peptide levels were also measured 30 minutes, 60 minutes, and 1 week after mode switching. Plasma atrial natriuretic peptide and brain natriuretic peptide levels were significantly higher in the nonphysiological pacing group than in the physiological pacing group, whereas these values were similar in the DDD and AAI pacing groups. One week after switching from DDD to VVI, plasma atrial natriuretic peptide and brain natriuretic peptide levels were significantly increased, however no significant changes were observed after switching to AAI. Based on a multivariate regression analysis of noninvasive clinical parameters, only a low plasma brain natriuretic peptide was significantly correlated with physiological pacing. We conclude that: (1) plasma brain natriuretic peptide, like atrial natriuretic peptide, is influenced by the pacing mode, but is not influenced by electrical stimulation; and (2) low plasma brain natriuretic peptide is important in relation to physiological pacing.

Calibrated Thermal Microscopy of the Tool-Chip Interface in Machining (2000)

A critical parameter in predicting tool wear during machining and in accurate computer simulations of machining is the spatially-resolved temperature at the tool-chip interface. We describe the development and the calibration of a nearly diffraction-limited thermal-imaging microscope to measure the spatially-resolved temperatures during the machining of an AISI 1045 steel with a tungsten-carbide tool bit. The microscope has a target area of 0.5 mm X 0.5 mm square region with a < 5 micrometers spatial resolution and is based on a commercial InSb 128 X 128 focal plane array with an all reflective microscope objective. The minimum frame image acquisition time is < 1 ms. The microscope is calibrated using a standard blackbody source from the radiance temperature calibration laboratory at the National Institute of Standards and Technology, and the emissivity of the machined material is deduced from the infrared reflectivity measurements. The steady-state thermal images from the machining of 1045 steel are compared to previous determinations of tool temperatures from micro-hardness measurements and are found to be in agreement with those studies. The measured average chip temperatures are also in agreement with the temperature rise estimated from energy balance considerations. From these calculations and the agreement between the experimental and the calculated determinations of the emissivity of the 1045 steel, the standard uncertainty of the temperature measurements is estimated to be about 45 degree(s)C at 900 degree(s)C.
Design and validation of SVPWM algorithm for thermal protection of T-type three-level inverters (2015)

This paper investigates the design and validation of a new space vector pulse width modulation (SVPWM) algorithm for thermal protection of T-type three-level inverters. Thermal overheating is the main cause of shortened-lifetime and open-circuit faults of power devices. Power devices are subjected to thermal overheating due to degradation of power devices due to continuous overloading and power cycling, and degradation and faults in cooling systems. When a thermal overheating is detected in one of the switching devices, the proposed algorithm is applied to protect the thermally-overheated switch from being short/open-circuited and hence preventing the total system from malfunction. The lifetime and the reliability of the inverter have been enhanced considerably by a simple modification of the conventional SVPWM algorithm and without adding any additional hardware or complex calculations. In addition to that, the proposed algorithm does not deteriorate the inverter's output current. The proposed thermal protection SVPWM algorithm has been designed, simulated, and experimentally validated at different operating conditions.

A ChIP-seq defined genome-wide map of vitamin D receptor binding: Associations with disease and evolution (2010)

Initially thought to play a restricted role in calcium homeostasis, the pleiotropic actions of vitamin D in biology and their clinical significance are only now becoming apparent. However, the mode of action of vitamin D, through its cognate nuclear vitamin D receptor (VDR), and its contribution to diverse disorders, remain poorly understood. We determined VDR binding throughout the human genome using chromatin immunoprecipitation followed by massively parallel DNA sequencing (ChIP-seq). After calcitriol stimulation, we identified 2776 genomic positions occupied by the VDR and 229 genes with significant changes in expression in response to vitamin D. VDR binding sites were significantly enriched near autoimmune and cancer associated genes identified from genome-wide association (GWA) studies. Notable genes with VDR binding included IRF8, associated with MS, and PTPN2 associated with Crohn's disease and T1D. Furthermore, a number of single nucleotide polymorphism associations from GWA were located directly within VDR binding intervals, for example, rs13385731 associated with SLE and rs947474 associated with T1D. We also observed significant enrichment of VDR intervals within regions of positive selection among individuals of Asian and European descent. ChIP-seq determination of transcription factor binding, in combination with GWA data, provides a powerful approach to further understanding the molecular bases of complex diseases.
Personal computing: compuvision or teleputer (1990)

Historically, the computer and communication industries have been separate, although both worked with electronically encoded information and shared similar technology. The regulations that kept computing and communication apart began to crumble in 1956 when the FCC ruled that Hush-a-Phone could attach equipment to the AT&T network under special circumstances. In 1959 they opened a portion of the microwave spectrum, and the 1968 Carter-phone case allowed all kinds of equipment to be tied to the network. Today, IBM is in the communication business and AT&T markets computers, but many feel that the distinction among computing, communication, news, and entertainment industries will blur or disappear. The question is, who will lead the charge—the computer companies, entertainment companies, toy companies, or phone companies? To put it another way, will the home computer swallow up the television set or will the television set become a computer in disguise? Not surprisingly, computer companies and entertainment companies have different answers to this question, and the debate was brought into focus by announcements at the Fifth Microsoft International CD-ROM Conference and Exposition. Let us look at the question of the home computer versus the smart TV and then come back to some of the other interesting announcements at the show and the current state of multimedia applications.
Differential Effect of Quetiapine on Depressive Symptoms in Patients with Partially Responsive Schizophrenia (2003)

While atypical antipsychotics appear to be effective in reducing depressive symptoms in the acute phase of schizophrenia, little is known about their efficacy in patients with ongoing symptoms. The present study assessed whether quetiapine (Seroquel) is more effective than haloperidol in treating depressive symptoms in patients with persistent positive symptoms, and investigated whether this effect is independent, or secondary to, reductions in other symptoms such as positive, negative or extrapyramidal symptoms. Patients with schizophrenia and a history of partial refractoriness to conventional antipsychotics who had not responded to 4 weeks of fluphenazine treatment (20 mg/day) were randomized to receive either quetiapine (600 mg/day) or haloperidol (20 mg/day) for a further 8 weeks. Change in the Positive and Negative Syndrome Scale depression factor score from baseline to endpoint was calculated and path analyses were performed on data from 269 patients. Quetiapine produced a greater reduction in depressive scores than haloperidol (-1.60 versus -0.54; p = 0.006). The path analyses indicated that this was a direct effect on depressive symptoms. These findings extend the evidence for an antidepressant effect for the novel antipsychotics in schizophrenia, and suggest that this is not limited to acutely psychotic patients.
Differential Roles of Exoloop 1 of the Human Follicle-stimulating Hormone Receptor in Hormone Binding and Receptor Activation (1995)

The follicle-stimulating hormone (FSH) receptor is a member of the glycoprotein hormone receptor subfamily of the seven-transmembrane receptor superfamily. These receptors have an extracellular N-terminal half of approximately 350 amino acids and a membrane-associated C-terminal half of approximately 350 amino acids. The N-terminal halves have the high affinity hormone binding site. On the other hand, the C-terminal half of the lutropin/choriogonadotropin receptor has the receptor activation site. However, little is known about the activation site and mechanism of the FSH receptor, although the existing evidence indicates crucial differences in the activation of the FSH receptor and the lutropin/choriogonadotropin receptor. As a first step to resolve this issue, we examined the upstream juxtamembrane five amino acids, Asp405-Ile406-His407-Thr408-Lys409, of the exoloop 1. Ala scan and multi-substitutions show that the five amino acid sequence is important for both hormone binding and receptor activation to induce cAMP synthesis, despite its short length. Specifically, His407 is important for high affinity hormone binding, whereas Asp405, Thr408, and Lys409 are crucial for receptor activation. The data suggest that the five amino acids may form a turn of helix that is an extension of the transmembrane helix 2. In this helical arrangement, Asp405, Thr408, and Lys409 are grouped to form a hydrophilic face of the helix, suggesting a correlation between this arrangement and receptor activation. In addition, the diverse and differential roles of the five amino acids indicate that high affinity hormone binding and receptor activation are discernible functions. These novel observations will be helpful for understanding the activation mechanism of the FSH receptor.
Sensorless Control for SPMSM With Concentrated Windings Using Multisignal Injection Method (2014)

Surface-mounted permanent magnet synchronous machine with concentrated windings (cwSPMSM) is a high-performance drive machine and has been adopted in many applications. The difficulty of implementing its sensorless control at low and zero speeds is its multiple saliencies, which is much more significant than most other ac machines. The traditional decoupling methods provide successful results only under the condition that high-order saliencies are not stronger than half of the primary saliency. Furthermore, the behavior of the multiple saliencies is principally frequency dependent. Based on the characteristics of such machines, this paper proposes a multisignal injection method for realizing sensorless control. This method injects multiple high-frequency signals with different frequencies and magnitudes into the machine. Different frequency components in the response current signals are demodulated and then combined together to get the clear primary saliency signal, which is used to identify the rotor position. This new method was validated using a cwSPMSM at low speed. The experimental results proved the effectiveness and accuracy of the new method.
Isolates of<i>Salmonella enterica</i>Enteritidis PT4 with enhanced heat and acid tolerance are more virulent in mice and more invasive in chickens (1996)

Two Enteritidis PT4 isolates which differed in inherent tolerance to heat, acid, H2O2 and the ability to survive on surfaces were used to infect mice, day-old chicks or laying hens. The acid-, heat-, H2O2- and surface-tolerant isolate was more virulent in mice and more invasive in laying hens, particularly in reproductive tissue. However, no significant differences were observed in behaviour in chicks. Both PT4 isolates were able to infect chicks housed in the same room as infected birds, although the heat-tolerant isolate survived significantly better than the heat-sensitive one in aerosols.
