Purification, characterization, and amino-terminal sequence of rat ovarian receptor for luteinizing hormone/human choriogonadotropin (1989)

The luteinizing hormone (LH)/human choriogonadotropin (hCG) receptor of rat ovary was solubilized with Lubrol PX in the presence of 20% glycerol and protease inhibitors, and purified by one-step affinity chromatography. Purified receptor had a specific hCG binding capacity of 4900 pmol/mg protein, and displayed a single class of high affinity binding sites (Ka = 6.20 X 10(9) M-1). An 11,200-fold purification over the starting crude homogenate was achieved. The purified LH/hCG receptor was identified by sodium dodecyl sulfate-gel electrophoresis and silver staining as a single protein of 92 kDa. The ability of the purified 92-kDa protein to specifically bind hormone was demonstrated by electroblotting onto Immobilon P membrane, incubation with 125I-labeled hCG, and autoradiography of the blot. In addition to a 92-kDa band, ligand blotting also yielded a 170-kDa band representing receptor dimer. Covalent cross-linking of hCG, with isotope in either the alpha- or beta-subunit, to membrane-bound receptor produced complexes that contained a single receptor component of approximately 92 kDa. The cross-linking studies indicated that both subunits interact with receptor and also suggested receptor dimer formation. Following sodium dodecyl sulfate-electrophoresis, purified receptor was electroblotted onto polyethylenimine-treated glass fiber filters for direct microsequencing in a gas-phase sequenator. Eleven cycles of sequence analysis yielded the unique sequence: NH2-Arg-Glu-Leu-Ser-Gly-Ser-Leu-XXX-Pro-Glu-Pro-COOH. These results indicate that the rat ovarian LH/hCG receptor is a protein of 92 kDa which can be easily purified in microgram amounts. This study also describes a relatively simple technique for electroblotting and microsequencing that should be applicable to other membrane-bound hormone receptors.
Role of Ceftiofur in Selection and Dissemination of bla CMY-2 -Mediated Cephalosporin Resistance in Salmonella enterica and Commensal Escherichia coli Isolates from Cattle (2009)

Third-generation cephalosporin resistance of Salmonella and commensal Escherichia coli isolates from cattle in the United States is predominantly conferred by the cephamycinase CMY-2, which inactivates beta-lactam antimicrobial drugs used to treat a wide variety of infections, including pediatric salmonellosis. The emergence and dissemination of bla(CMY-2)(-)-bearing plasmids followed and may in part be the result of selection pressure imposed by the widespread utilization of ceftiofur, a third-generation veterinary cephalosporin. This study assessed the potential effects of ceftiofur on bla(CMY-2) transfer and dissemination by (i) an in vivo experimental study in which calves were inoculated with competent bla(CMY-2)-bearing plasmid donors and susceptible recipients and then subjected to ceftiofur selection and (ii) an observational study to determine whether ceftiofur use in dairy herds is associated with the occurrence and frequency of cephalosporin resistance in Salmonella and commensal E. coli. The first study revealed bla(CMY-2) plasmid transfer in both ceftiofur-treated and untreated calves but detected no enhancement of plasmid transfer associated with ceftiofur treatment. The second study detected no association (P = 0.22) between ceftiofur use and either the occurrence of ceftiofur-resistant salmonellosis or the frequency of cephalosporin resistance in commensal E. coli. However, herds with a history of salmonellosis (including both ceftiofur-resistant and ceftiofur-susceptible Salmonella isolates) used more ceftiofur than herds with no history of salmonellosis (P = 0.03) These findings fail to support a major role for ceftiofur use in the maintenance and dissemination of bla(CMY-2)-bearing plasmid mediated cephalosporin resistance in commensal E. coli and in pathogenic Salmonella in these dairy cattle populations.

Dual-wavelength Fourier ptychography using a single LED (2018)

We propose dual-wavelength Fourier ptychography for topographic measurement. To extend the axial measurement range, a single light-emitting diode (LED) and two appropriate bandpass filters are employed. This provides a speckle-free phase image, and reduces the possibility of a systematic error, which yields a high-quality topographic image. The proposed system can measure the surface topography in the range of nano- to micro-structures. The performance of the system is experimentally verified.
VTP-CSMA: A Virtual Token Passing Approach for Real-Time Communication in IEEE 802.11 Wireless Networks (2007)

Currently, there is a trend towards the implementation of industrial communication systems using wireless networks. However, keeping up with the timing constraints of real-time traffic in wireless environments is a hard task. The main reason is that real-time devices must share the same communication medium with timing unconstrained devices. The VTP-CSMA architecture has been proposed to deal with this problem. It considers an unified wireless system in one frequency band, where the communication bandwidth is shared by real-time and non-real-time communicating devices. The proposed architecture is based on a virtual token passing (VTP) procedure that circulates a virtual token among real-time devices. This virtual token is complemented by an underlying traffic separation mechanism that prioritizes the real-time traffic over the non-real-time traffic. This is one of the most innovative aspects of the proposed architecture, as most part of real-time communication approaches are not able to handle timing unconstrained traffic sharing the same communication medium. A ring management procedure for the VTP-CSMA architecture is also proposed, allowing real-time stations to adequately join/leave the virtual ring.
Adult diet as a factor affecting biology of the sandfly Phlebotomus papatasi (Diptera: Psychodidae). (1991)

The effects of adult nutrients on egg retention, immature development and adult survival of P. papatasi, the important vector of leishmaniasis in Egypt were investigated. The tested nutrients were distilled water, overripe fig fruits, guinea pig blood, sucrose solution and alternative meals of blood and sucrose. Egg retention was observed in females irrespective to the type of offered nutrient (r = 0.21) but higher proportion (47%) of blood fed females had retained eggs. Duration of the life cycle was higher for the progeny of fig fed females (P less than 0.05) and mean generation time was longer for sucrose fed females (P less than 0.05). Such nutritional effect on life cycle was observed only for pre-oviposition periods and no extend effect on larval or pupal durations. The survivorship rates for eggs through adults were similar (P greater than 0.05). It is estimated that the population would increase by Ca. 15, 11, 10 and 7 folds if the mother female was fed blood, sucrose, fig or distilled water respectively. The mean life time differed significantly (P less than 0.05) among females fed on different nutrients with the highest co (life expectancy at emergence) value (14.98 +/- 2.75 days) for sucrose fed females. Males fed on distilled water, fig fruits or sucrose solution were with similar longevities P greater than 0.05). In respect to leishmania transmission, the calculated expectancies for female life beyond the infective age indicated that blood-sucrose fed females have higher capability than those fed on sucrose blood or blood alone.

Isolation of Transcription Factor Complexes from Arabidopsis Cell Suspension Cultures by Tandem Affinity Purification (2011)

Defining protein complexes is critical to virtually all aspects of cell biology because most cellular processes are regulated by stable or more dynamic protein interactions. Elucidation of the protein-protein interaction network around transcription factors is essential to fully understand their function and regulation. In the last decade, new technologies have emerged to study protein-protein interactions under near-physiological conditions. We have developed a high-throughput tandem affinity purification (TAP)/mass spectrometry (MS) platform for cell suspension cultures to analyze protein complexes in Arabidopsis thaliana. This streamlined platform follows an integrated approach comprising generic Gateway-based vectors with high cloning flexibility, the fast generation of transgenic suspension cultures, TAP adapted for plant cells, and tandem matrix-assisted laser desorption ionization MS for the identification of purified proteins. Recently, we evaluated the GS tag, originally developed to study mammalian protein complexes, that combines two IgG-binding domains of protein G with a streptavidin-binding peptide, separated by two tobacco etch virus cleavage sites. We found that this GS tag outperforms the traditional TAP tag in plant cells, regarding both specificity and complex yield. Here, we provide detailed protocols of the GS-based TAP platform that allowed us to characterize transcription factor complexes involved in signaling in response to the plant phytohormone jasmonate.
Genome-Wide SNP Analysis Reveals Distinct Origins of Trypanosoma evansi and Trypanosoma equiperdum (2017)

Trypanosomes cause a variety of diseases in man and domestic animals in Africa, Latin America, and Asia. In the Trypanozoon subgenus, Trypanosoma brucei gambiense and Trypanosoma brucei rhodesiense cause human African trypanosomiasis, whereas Trypanosoma brucei brucei, Trypanosoma evansi, and Trypanosoma equiperdum are responsible for nagana, surra, and dourine in domestic animals, respectively. The genetic relationships between T. evansi and T. equiperdum and other Trypanozoon species remain unclear because the majority of phylogenetic analyses has been based on only a few genes. In this study, we have conducted a phylogenetic analysis based on genome-wide SNP analysis comprising 56 genomes from the Trypanozoon subgenus. Our data reveal that T. equiperdum has emerged at least once in Eastern Africa and T. evansi at two independent occasions in Western Africa. The genomes within the T. equiperdum and T. evansi monophyletic clusters show extremely little variation, probably due to the clonal spread linked to the independence from tsetse flies for their transmission.
Environment and Process Adaptive Low Power Wireless Baseband Signal Processing Using Dual Real-Time Feedback (2009)

As technology scales below the 45 nm CMOS technology node, RF front ends and baseband processors will need to be aggressively overdesigned to work reliably under worst case channel (environment) conditions as well as worst case manufacturing variations. In this paper, a new dual feedback based design approach is proposed that allows the baseband unit of a wireless OFDM system to adapt dynamically to channel conditions as well as manufacturing process variations. Two nested feedback control loops are used. The first allows the baseband SNR to increase when channel conditions are good and vice versa by modulating system wordlength. The second modulates the system supply voltage in response to the resulting changing wordlength values. Both feedback loops are designed to allow the processor to operate at the minimum power consumption possible without exceeding a specified overall bit error rate across process variability conditions and dynamically changing noise conditions.
Impact of Overdiagnosis on Long-Term Breast Cancer Survival (2019)

Elucidating whether and how long-term survival of breast cancer is mainly due to cure after early detection and effective treatment and therapy or overdiagnosis resulting from the widespread use of mammography provides a new insight into the role mammography plays in screening, surveillance, and treatment of breast cancer. Given information on detection modes, the impact of overdiagnosis due to mammography screening on long-term breast cancer survival was quantitatively assessed by applying a zero (cured or overdiagnosis)-inflated model design and analysis to a 15-year follow-up breast cancer cohort in Dalarna, Sweden. The probability for non-progressive breast cancer (the zero part) was 56.14% including the 44.34% complete cure after early detection and initial treatment and a small 11.80% overdiagnosis resulting from mammography screening program (8.94%) and high awareness (2.86%). The 15-year adjusted cumulative survival of breast cancer was dropped from 88.25% to 74.80% after correcting for the zero-inflated part of overdiagnosis. The present findings reveal that the majority of survivors among women diagnosed with breast cancer could be attributed to the cure resulting from mammography screening and accompanying effective treatment and therapy and only a small fraction of those were due to overdiagnosis.
Sensor fused indoor positioning using dual band WiFi signal measurements (2015)

In this paper, signal strengths from known WiFi access points are used together with a particle filter to perform indoor navigation. It is shown that more information is obtained by using signals of both 2.4 and 5.0 GHz, compared to using only one frequency. Thus, using both frequencies provides a more accurate positioning. The second contribution is an algorithm where WiFi measurements are combined with pedestrian dead reckoning (PDR), which is based on step counting using an accelerometer and hypotheses of the heading using a gyroscope. This was found to provide further accuracy compared to more conventional methods.

Exploring Early Glaucoma and the Visual Field Test: Classification and Clustering Using Bayesian Networks (2014)

Bayesian networks (BNs) are probabilistic models used for classification and clustering in several fields. Their ability to deal with unobserved variables and to integrate data and expert knowledge make them an appropriate technique for modeling eye functionality measurements in glaucoma. In this study, a set of BNs is used to simultaneously perform classification of early glaucoma and cluster data into different stages of disease. A novel learning algorithm that combines clustering and quasi-greedy search is also proposed. The classification performances of the models are evaluated on an independent dataset, while the clusters are compared to K-means, previous publications, and direct knowledge. The use of clustering and structure learning enabled the exploration of the visual field patterns of the disease while obtaining good results both on pre- (50% sensitivity at 90% specificity) and post- (85% sensitivity at 90% specificity) diagnosis data. Clusters obtained were insightful and in conformity with consolidated knowledge in the field.
Size-based scheduling policies with inaccurate scheduling information (2004)

Size-based scheduling policies, such as shortest remaining processing time (SRPT), have been studied since the 1960s and have been applied in various areas, including packet networks and Web server scheduling. SRPT has been proven to be optimal in the sense that it yields - compared to any other conceivable strategy - the smallest mean value of occupancy and therefore also of waiting and delay time. One important prerequisite to applying size-based scheduling is to know the sizes of all jobs in advance, which are unfortunately not always available. No work has been done to study the performance of size-based scheduling policies when only inaccurate scheduling information is available. We study the performance of SRPT and fair sojourn protocol (FSP) as a function of the correlation coefficient between the actual job sizes and estimated job sizes. We have developed a simulator that supports both M/G/l/m and G/G/n/m queuing models. The simulator can be driven by trace data or synthetic data produced by a workload generator we have developed that allows us to control the correlation. The simulations show that the degree of correlation has a dramatic effect on the performance of SRPT and FSP, and that a reasonably good job size estimator makes both SRPT and FSP outperform processor sharing (PS) in both mean response time and slowdown.
Toward quantitative digital histopathology for prostate cancer: comparison of inter-slide interpolation methods for tumour measurement (2013)

Accurate pathology assessment of post-prostatectomy specimens is important to determine the need for and to guide potentially life-saving adjuvant therapy. Digital pathology imaging is enabling a transition to a more objective quantification of some surgical pathology assessments, such as tumour volume, that are currently visually estimated by pathologists and subject to inter-observer variability. One challenge for tumour volume quantification is the traditional 3–5 mm spacing of images acquired from sections of radical prostatectomy specimens. Tumour volume estimates may benefit from a well-motivated approach to inter-slide tumour boundary interpolation. We implemented and tested a level set-based interpolation method and found that it produced 3D tumour surfaces that may be more biologically plausible than those produced via a simpler nearest-slide interpolation. We found that the simpler method produced larger tumour volumes, compared to the level set method, by a median factor of 2.3. For contexts where only tumour volume is of interest, we determined that the volumes produced via the simpler method can be linearly adjusted to the level setproduced volumes. The smoother surfaces from level set interpolation yielded measurable differences in tumour boundary location; this may be important in several clinical/research contexts (e.g. pathology-based imaging validation for focal therapy planning).
Speed of line protection - can we break free of phasor limitations? (2015)

Today's relays are predominantly based on phasors, and as such, they incur a delay associated with the full-cycle observation window required for accurate phasor estimation. Considerable improvement in speed is possible by using information in the transients of voltages and currents. We review a number of protection techniques, including directional elements, direct tripping underreaching elements, and differential elements that significantly speed up line protection.

The Role of Apelin in Cardiovascular Diseases, Obesity and Cancer (2018)

Apelin is an endogenous peptide identified as a ligand of the G protein-coupled receptor APJ. Apelin belongs to the family of adipokines, which are bioactive mediators released by adipose tissue. Extensive tissue distribution of apelin and its receptor suggests, that it could be involved in many physiological processes including regulation of blood pressure, body fluid homeostasis, endocrine stress response, cardiac contractility, angiogenesis, and energy metabolism. Additionally, this peptide participates in pathological processes, such as heart failure, obesity, diabetes, and cancer. In this article, we review current knowledge about the role of apelin in organ and tissue pathologies. We also summarize the mechanisms by which apelin and its receptor mediate the regulation of physiological and pathological processes. Moreover, we put forward an indication of apelin as a biomarker predicting cardiac diseases and various types of cancer. A better understanding of the function of apelin and its receptor in pathologies might lead to the development of new medical compounds.
