FOAM CELL APOPTOSIS AND THE DEVELOPMENT OF THE LIPID CORE OF HUMAN ATHEROSCLEROSIS (1996)

A characteristic feature of the advanced atherosclerotic lesion is the acellular lipid core, which appears to result at least partly from the death of macrophage foam cells. This study shows that foam cell death at the edge of the lipid core includes both necrosis and apoptosis and that remnants of apoptotic nuclei are present within the lipid core. Apoptotic cells were identified by transmission electron microscopy and by nick end-labelling using terminal deoxynucleotidyl transferase (TUNEL). Some TUNEL-positive cells also expressed proliferating cell nuclear antigen (PCNA). The cause of foam cell death in atherogenesis is unknown, but oxidized low-density lipoprotein (LDL) can cause macrophage apoptosis in vitro and might therefore play a role in the formation and enlargement of the lipid core.
Animal venom studies: Current benefits and future developments (2015)

Poisonous organisms are represented in many taxa, including kingdom Animalia. During evolution, animals have developed special organs for production and injection of venoms. Animal venoms are complex mixtures, compositions of which depend on species producing venom. The most known and studied poisonous terrestrial animals are snakes, scorpions and spiders. Among marine animals, these are jellyfishes, anemones and cone snails. The toxic substances in the venom of these animals are mainly of protein and peptide origin. Recent studies have indicated that the single venom may contain up to several hundred different components producing diverse physiological effects. Bites or stings by certain poisonous species result in severe envenomations leading in some cases to death. This raises the problem of bite treatment. The most effective treatment so far is the application of antivenoms. To enhance the effectiveness of such treatments, the knowledge of venom composition is needed. On the other hand, venoms contain substances with unique biological properties, which can be used both in basic science and in clinical applications. The best example of toxin application in basic science is α-bungarotoxin the discovery of which made a big impact on the studies of nicotinic acetylcholine receptor. Today compositions of venom from many species have already been examined. Based on these data, one can conclude that venoms contain a large number of individual components belonging to a limited number of structural types. Often minor changes in the amino acid sequence give rise to new biological properties. Change in the living conditions of poisonous animals lead to alterations in the composition of venoms resulting in appearance of new toxins. At the same time introduction of new methods of proteomics and genomics lead to discoveries of new compounds, which may serve as research tools or as templates for the development of novel drugs. The application of these sensitive and comprehensive methods allows studying either of venoms available in tiny amounts or of low abundant components in already known venoms.
Clot Density Determination of Fibrinogen in Experimental Myocardial Infarction (1955)

1. In vitro experiments indicate that the clot density determination of fibrinogen may be applicable to either human as well as canine plasma. 2. Fifty dogs were subjected to a) sham-operation, b) high coronary artery ligation, c) low coronary artery ligation. 3. Significant differences in the mean fibrinogen levels were found in the three groups corresponding to the various degrees of myocardial necrosis. 4. These results seem to bear out a previously reached clinical impression that the maximum fibrinogen concentration parallels the extent of the myocardial infarct.
Ethanol denaturation of soya bean protein antigens (1982)

Abstract Glycinin and β‐conglycinin, globular proteins present in soya bean meal, were denatured by extracting the meal with ethanol under several different conditions of alcohol concentration and temperature. Antigenic activities of these proteins in saline extracts of the processed meal were determined by haemagglutination inhibition assay and immunoelectrophoresis. Products extracted with low (< 30%) and high (>96%) concentrations of ethanol at 70–80°C retained antigenic activity, whereas samples prepared with 55–76% ethanol at 70–80°C contained very little extractable antigenic protein. Antigenic activities of glycinin and β‐conglycinin were relatively high in products extracted with concentrations of ethanol between 57–86% when the extraction temperature was <50°C.
Microfluidic chip-based liquid–liquid extraction and preconcentration using a subnanoliter-droplet trapping technique (2005)

A robust and simple approach for microfluidic liquid-liquid (L-L) extraction at the subnanoliter-scale was developed for on-chip sample pretreatment. Organic solvent droplets of a few hundred pL were trapped within micro recesses fabricated in the channel walls of a microfabricated glass chip. L-L extraction was performed by delivering aqueous samples through the channel, with the sample stream continuously flowing adjacent to the droplets. The analytes in aqueous streams were enriched within the droplet with high preconcentration factors owing to both phase transfer and dissolution of organic solvent into the bypassing aqueous sample. An aqueous solution of butyl rhodamine B (BRB) and 1-hexanol were used, respectively, as sample and extractant to demonstrate the performance of the system. The fluorescence intensity of the dye extracted into the droplet was monitored in situ by LIF. The system proved to be an efficient means for achieving high enrichment factors of over 1000, with sample consumption of a few microL. Quantitative measurement of the extracted analyte was achieved with a linear response in the range 1 x 10(-9)-8 x 10(-7) M BRB. The precision of the measured fluorescence values for a 10(-7) M BRB standard with a 12.5 min preconcentration period was 6.6% RSD (n = 5).
AN APPROXIMATE ANALYSIS OF THE COLLAPSE OF THIN CYLINDRICAL SHELLS UNDER AXIAL LOADING (1960)

An approximate theory for the process is derived, leading to a solution of the type P = Ct1.5√D, where P is the collapse load, t the shell thickness, D the shell diameter, and C a constant for any given material. Good agreement is exhibited between this relationship and experimental results.
Application-specific reliable data transfer in wireless sensor networks (2007)

A wireless sensor network (WSN) is a collection of sensor nodes and base stations connected via wireless medium. It sends data collected from the nodes to the base stations for generating information. The size and low cost of the sensor nodes as well as the WSN's ability to connect without wired links are its key advantages which enable it to be deployed in hostile or inaccessible environments at low cost. However, WSNs suffer from high data loss due to the inherent weaknesses in a wireless transmission medium, transmission problems in hostile environments due to human interference, etc. and node failures due to limited energy of sensor nodes. Hence ensuring data transfer with minimum loss i.e. reliable data transfer is very important in WSNs. The amount of loss tolerated is application dependent. We present a reliable protocol for data transfer from a base station to sensor nodes for time-critical applications in WSNs with zero tolerance for data loss. The protocol is based on hop-by-hop detection and recovery of lost data packets, out-of-sequence forwarding of packets and delayed request for missing packets at each node with non-acknowledgement of packets at each receiving node. We present a detailed analysis of the advantages of the key features of our protocol over other alternatives. The superiority of our protocol over an established protocol PSFQ is demonstrated via extensive simulations, in terms of both the delivery time of the entire data (sent from the base station to the sensor nodes) and the number of messages exchanged in the network during this process. In addition, we present two methods, one, for ensuring that at least one packet is delivered to a node in non-acknowledgement based systems and another, for sending reports from destination nodes to the base station respectively. We explore different methods for further improvement of protocol performance: (1) use of effective degree of a node in determining the optimum delay for requesting data packets missing at nodes, (2) variation of the priority order for sending different types of messages at nodes and, (3) selective response to requests for packets at nodes.
Effect of Cultivation on the Nitrogen Distribution in Soils (1964)

Abstract The effect of cultivation on the nitrogen distribution in soils was studied by determining total N, nonexchangeable ammonium N, nonhydrolyzable N, and hydrolyzable (total, ammonium, hexosamine, amino acid, unidentified) N in 10 virgin soils and their cultivated analogues. Cultivation led to a marked decrease in all forms of N, excepting nonexchangeable ammonium N, but, on the average, had little effect on the percentage distribution of N. The average percent loss of total N on cultivation was 36.2%, and the average losses of different forms of N, calculated as percentages of the loss in total N, decreased in the order: hydrolyzable N (70.5%) > amino acid N (29.8%) > nonhdrolyzable N (29.5%) > unidentified hydrolyzable N (20.0%) > hydrolyzable ammonium N (17.1%) > hexosamine N (3.5%) > nonexchangeable ammonium N (0.5%). On the average, cultivation led to small increases in the proportions of total N as nonexchangeable ammonium N, Hydrolyzable N, hexosamine N, and hydrolyzable ammonium N, and to small decreases in the proportions as nonhydrolyzable N, amino acid N, and unidentified hydrolyzable N. The average percent losses of different forms of N on cultivation decreased in the order: amino acid N (43.0%) > nonhydrolyzable N (39.4%) > total N (36.2%) > total hydrolyzable N (35.2%) > unidentified hydrolyzable N (34.5%) > hydrolyzable ammonium N (28.6%) > hexosamine N (27.6%) > nonexchangeable ammonium N (0.2%).
Ozonation Pretreatment of Gold-Silver Pyritic Minerals (2007)

The use of ozone for the oxidation of cyanidation wastewater has been studied since the 1950's. In the last 2 decades, the use of ozone to oxidize sulfide ores has been studied. This report presents some of the results obtained concerning the use of ozone in the oxidation of raw ores containing gold and silver as well as the treatment of tails or residues of the cyanidation process. The results show that oxidation treatment with ozone prior to cyanidation may help to optimize this process, mainly through reduction of the consumption of cyanide.
Analgesic efficacy and safety of nefopam vs. propacetamol following hepatic resection* (2001)

In order to compare the morphine-sparing effect, analgesic efficacy and tolerance of nefopam and propacetamol given at their highest recommended doses, 120 patients undergoing elective hepatic resection were randomly assigned to receive postoperative intravenous patient-controlled analgesia with morphine alone, or in combination with nefopam (20 mg.4 h-1) or propacetamol (2 g.6 h-1). Compared with the control group (43 [7-92] mg), median [range] cumulative morphine consumption for 24 h after the study started was halved in the nefopam group (21 [3-78] mg, p <0.001) and 20% lower in the propacetamol group (35 [6-84] mg, p = 0.15). Analgesia was superior in the nefopam group despite the lower morphine consumption. Adverse effects were comparable in the three groups, except for significantly more nausea in the control group (39% vs. 17 and 26% in the nefopam and propacetamol groups, respectively) and more sweating in the nefopam group (17% vs. 0 and 3% in the control and propacetamol groups, respectively). Overall patient satisfaction was better (p < 0.001) in patients given nefopam (97%) than those receiving morphine alone (82%) or propacetamol (74%).

A Review of Recent Laser Illumination Events in the Aviation Environment (2006)

Flight crewmember exposure to laser light, while operating an aircraft at night, has resulted in glare, flashblindness, and afterimage. Temporary visual impairment and the distraction, disorientation, and discomfort that can accompany it often result in hazardous situations. A database of aviation reports involving laser illumination of flight crewmembers has been established and maintained at the Civil Aerospace Medical Institute. A review of recent laser illumination reports was initiated to investigate the significance of these events. Reports of high-intensity light illumination of aircraft were collected from Federal Aviation Administration (FAA) regional offices, Transportation Security Administration, Department of Homeland Security/Federal Bureau of Investigation Information Bulletins, the FAA's Office of Accident Investigation, newspaper articles, and interviews with pilots submitted by the airline industry. Reports that involved laser exposures of civilian aircraft in the United States were analyzed for the 13-month period (January 1, 2004 - January 31, 2005). There were 90 reported instances of laser illumination during the study period. A total of 53 reports involved laser exposure of commercial aircraft. Lasers illuminated the cockpit in 41 (46%) of the incidents. Of those, 13 (32%) incidents resulted in visual impairment or distraction to a pilot, including 1 incident that reportedly resulted in ocular injury. Nearly 96% of these reports occurred in the last 3 months of the study period. There were no aviation accidents in which laser light illumination was found to be a contributing factor. The study of laser illumination incidents in the national airspace system can identify the operational problems that result from such events. Improved reporting and analysis of laser events enhances aviation safety.
The utility of the arthritis impact measurement scales for patients with psoriatic arthritis. (1992)

The Arthritis Impact Measurement Scales (AIMS) consists of 9 scales that measure physical function, pain and psychosocial function. It has been validated for use in various forms of arthritis, but not in psoriatic arthritis (PsA). The AIMS was administered to 145 patients attending our PsA clinic. We carried out simultaneous assessment of clinical measures of function, measures of disease activity, and measures of disease severity. Most scales of physical function were moderately to highly correlated with clinical measures of function (r = 0.33-0.57; p = 0.0001), measures of disease activity (r = 0.24-0.53, p = 0.003-0.0001), and measures of disease severity (r = 0.23-0.6; p = 0.02-0.0001). The pain scale was highly correlated with clinical measures of function and measures of disease activity (r = 0.38-0.58; p = 0.0001) but not with measures of disease severity. Of the psychosocial scales, the depression scale was moderately correlated with clinical measures of function (r = 0.27-0.3; p = 0.001-0.0001). Our data suggest that the physical function and pain scales are good indicators of overall function and disease activity and are valid for use in PsA.
WHAT'S A METAPHOR?: THE DEPORTATION OF A POET (1989)

For more than four years the United States government tried to deport feminist author Margaret Randall for the political content of her publications. The legal basis for the government's case against Randall was the McCarran-Walter Act, the infamous 1952 law that authorizes the government to exclude and deport non-citizens for any number of ill-defined ideological "crimes." The McCarran-Walter Act was passed during the height of the Cold War, and remains on the books to this day.
A Sense-based Registration Process for TDMA in IEEE 802.11 Network (2018)

TDMA implementation offer better fairness and throughput in IEEE 802.11. To implement TDMA, new registration process is needed, because current registration mechanism can disrupt TDMA process. This paper proposes a sense-based TDMA registration process using service slot and random timer. Simulation result shows, by using our mechanism, we can reduce the number of unused timeslot, and for 10 new nodes, each node only need 7 ms to complete the registration process.
On localization attacks against cloud infrastructure (2013)

One of the key characteristics of cloud computing is the device and location independence that enables the user to access systems regardless of their location. Because cloud computing is heavily based on sharing resource, it is vulnerable to cyber attacks. In this paper, we investigate a localization attack that enables the adversary to leverage central processing unit (CPU) resources to localize the physical location of server used by victims. By increasing and reducing CPU usage through the malicious virtual machine (VM), the response time from the victim VM will increase and decrease correspondingly. In this way, by embedding the probing signal into the CPU usage and correlating the same pattern in the response time from the victim VM, the adversary can find the location of victim VM. To determine attack accuracy, we investigate features in both the time and frequency domains. We conduct both theoretical and experimental study to demonstrate the effectiveness of such an attack.
Can Local Food Go Mainstream? (2010)

The supermarket is one of the 20th Century’s most important marketing innovations. The concept of the supermarket emerged in the 1930s, and supermarkets came to dominate food retailing in the two decades immediately after World War II. Made possible by rapid suburbanization of American cities and expansion of ownership of automobiles and refrigerators, supermarkets transformed business processes and competition for customers at the retail level. They also fostered expansion and new efficiencies for wholesalers and created new opportunities for food manufacturers to develop products for mass audiences. The basic hub and spoke distribution system that has evolved for supermarkets is built around large distribution centers located near interstate highways. These distribution centers receive full semi-trailer loads of product from suppliers and then send full semi-trailers out to individual stores daily or several times per week. Loads sent to stores are comprised of relatively small quantities of thousands of individual SKUs, or stock keeping units, needed to replenish the inventory of tens of thousands of SKUs stored on self-service shelves in a typical store. This system, which is supplemented by deliveries from specialty distributors and direct store deliveries by some suppliers, economizes on transportation and labor. With electronic transmission of orders and payment and computer-based tools that assist with ordering, pricing, and inventory management, this distribution system also keeps transaction costs to a minimum. It is ideally suited for sourcing consistent quality products at low cost from wherever they are available and so has been an integral part of an increasingly national and global food system. This mainstream supermarket distribution system favors large scale suppliers and facilitates long distance movement of products. Supermarket wholesale and retail companies usually prefer to work with a small number of large, reliable suppliers. At the same time, this system is remarkably resilient and quick to adapt. Can it be an effective channel for meeting the rapidly growing demand for local food products? Are there meaningful, long run prospects for a significant “relocalization” of supermarket offerings? While definitive answers to these questions are not yet apparent, there is emerging evidence that helps clarify how the relationship between the local foods movement and the supermarket industry may evolve.
[Pharmacological availability of erythromycin granules for children's use]. (1990)

Pharmaceutical availability of erythromycin granules with polymeric coating of different composition+ was studied. With an account of the ++anatomo-physiological features of a child organism and the properties of the antibiotic, acetylphthalyl cellulose in combination with hydroxypropyl methylcellulose or methyl cellulose was used as a film forming agent. The coated granules were estimated by such parameters as the time of disintegration and the rate of dissolution in various media. The results of the study showed that coating of the erythromycin granules with the film composed of acetylphthalyl cellulose and hydroxypropyl methylcellulose in the ratio of 8 to 2 provided the required protection of the antibiotic in acid media and high pharmaceutical availability of the drug.
A novel memory architecture for multicore SDR systems (2012)

For conventional wireless transceiver architectures with software-defined radio (SDR) technology, the communication between microcontrollers, DSPs (digital signal processors), and memories are through public shared buses. As wireless standards change frequently, the demands of bus bandwidth increase. To avoid bus bottlenecks and to get better performance, the wireless transceiver architectures with concatenate memories and concatenate buses are proposed. The application-specific instruction-set processor (ASIP) for the IEEE 802.11p standard and the electronic system-level (ESL) virtual platform for the inner receiver of IEEE 802.11p are built. Via the proposed transceiver architectures with concatenate memories and concatenate buses, the bandwidth of communication between DSPs through public shared buses can be saved because the communications between DSPs and concatenate memories are through concatenate buses.
Inhibition of endothelial progenitor cell differentiation by VEGI (2009)

Endothelial progenitor cells (EPCs) play a critical role in postnatal and tumor vasculogenesis. Vascular endothelial growth inhibitor (VEGI; TNFSF15) has been shown to inhibit endothelial cell proliferation by inducing apoptosis. We report here that VEGI inhibits the differentiation of EPCs from mouse bone marrow-derived Sca1(+) mononuclear cells. Analysis of EPC markers indicates a significant decline of the expression of endothelial cell markers, but not stem cell markers, on VEGI-treated cells. Consistently, the VEGI-treated cells exhibit a decreased capability to adhere, migrate, and form capillary-like structures on Matrigel. In addition, VEGI induces apoptosis of differentiated EPCs but not early-stage EPCs. When treated with VEGI, an increase of phospho-Erk and a decrease of phospho-Akt are detected in early-stage EPCs, whereas activation of nuclear factor-kappaB, jun N-terminal kinase, and caspase-3 is seen in differentiated EPCs. Furthermore, VEGI-induced apoptosis of differentiated EPC is, at least partly, mediated by death receptor-3 (DR3), which is detected on differentiated EPC only. VEGI-induced apoptosis signals can be inhibited by neutralizing antibodies against DR3 or recombinant extracellular domain of DR3. These findings indicate that VEGI may participate in the modulation of postnatal vasculogenesis by inhibiting EPC differentiation.
