Is hyperandrogenemia protective for fibrocystic breast disease in PCOS? (2011)

The aim of this study is to evaluate the fibrocystic breast disease rates and its association with different clinical, endocrine and metabolic parameters between main polycystic ovary syndrome (PCOS) phenotypes. One hundred thirty two consecutive women were included in the study. Body mass index, serum follicle-stimulating hormone, luteinizing hormone (LH), progesterone, estradiol, testosterone, dehydroepiandrosterone sulphate, fasting glucose, low density lipoprotein (LDL-C), total cholesterol, high density lipoprotein, insulin, insulin sensitivity and fibrocystic breast disease rates were compared among different phenotypes of PCOS. Group 1: Polycystic ovaries (PCO)-anovulation (n = 32), Group 2: Hyperandrogenemia (HA)-anovulation (n = 28), Group 3: HA-PCO (n = 29), Group 4: HA-PCO-anovulation (n = 43). There were statistically significant differences between the different phenotype groups in terms of waist-hip ratio (p = 0.006), serum LDL-C (p = 0.008), LH (p = 0.002), estradiol (p = 0.022), fasting glucose (p = 0.001), progesterone (p = 0.007), free testosterone levels (p < 0.001) and Ferriman-Gallwey (FG) scores (p < 0.001). Different phenotype groups had significantly different fibrocystic breast disease rates. (p = 0.016). Higher free testosterone >3 pg/dl was protective for fibrocystic disease (RR = 0.316, 95:% CI 0.109-0.912, p = 0.033). Higher FG scores were more protective for fibrocystic disease (RR = 0.005, 95:% CI 0.001-0.042, p < 0.001). Group 3 ovulatory PCOS patients with PCO and hyperandrogenemia phenotype had lower risk to develop fibrocystic disease, while higher rates were observed in group 1 anovulatory-normoandrogenemic PCOS patients. Hyperandrogenemia is protective for fibrocystic diseases in PCOS.
Purification of profilin from Saccharomyces cerevisiae and analysis of profilin-deficient cells. (1990)

We have isolated profilin from yeast (Saccharomyces cerevisiae) and have microsequenced a portion of the protein to confirm its identity; the region microsequenced agrees with the predicted amino acid sequence from a profilin gene recently isolated from S. cerevisiae (Magdolen, V., U. Oechsner, G. Müller, and W. Bandlow. 1988. Mol. Cell. Biol. 8:5108-5115). Yeast profilin resembles profilins from other organisms in molecular mass and in the ability to bind to polyproline, retard the rate of actin polymerization, and inhibit hydrolysis of ATP by monomeric actin. Using strains that carry disruptions or deletions of the profilin gene, we have found that, under appropriate conditions, cells can survive without detectable profilin. Such cells grow slowly, are temperature sensitive, lose the normal ellipsoidal shape of yeast cells, often become multinucleate, and generally grow much larger than wild-type cells. In addition, these cells exhibit delocalized deposition of cell wall chitin and have dramatically altered actin distributions.
A study on yow rate control of hydraulic-power-steering heavy duty vehicles (2007)

Hydraulic power steering systems, which can provide large steering assist force, are widely used for heavy-duty commercial vehicles. For the research of stability control system for commercial vehicles, the vehicle's combined simulation model, including IPS (integral power steering) system and vehicle body, was constructed. Then the linearization and order-reduction of simulation model were done for model based controller design. Comparing with experimental results, it was found that the established simulation model can adequately represent the vehicle dynamic behavior, and the linear low order model was also verified by comparison of eigenvalues and frequency domain responses. Finally, a yaw rate control system was designed based on the linear models and tested on the combined simulation model, which shows the validity of the simulation model and linearized low order model.
Combustion Performance of Porous Silicon-Based Energetic Composites (2009)

The combustion performance of oxidizer filled porous silicon(PSi) was studied. PSi samples with diameters of 2.54 cm were fabricated by electrochemical etching. The % porosity of the samples ranged from 55 to 82%. The samples were cut into 3-5 mm strips and filled with the oxidizers NaClO{sub 4} x 1H{sub 2}O, Ca(ClO{sub 4}){sub 2} x 4H{sub 2}O, S and perfluoropolyether (PFPE). The filled PSi was then burned by igniting the sample with a hot NiChrome{trademark} wire. The burns were recorded using high speed photography from which bring rates were calculated. That burning rates showed a strong dependency on quality of the oxidizer loading. The % porosity did not appear to have a direct affect on the burning rates for those studied. PSi loaded with NaClO{sub 4} x 1H{sub 2}O produced burning rates that ranged from 216-349 cm/s. PSi loaded with Ca(ClO{sub 4}){sub x}x 4 H{sub 2}O had burning rates of 154-285 cm/s. An S filled PSi sample burned a rate of 16 to 290 cm/s, and perfluoropolyether loaded PSi burned at a rate of 1.4 cm/s.

Multi-microphone speech dereverberation using expectation-maximization and Kalman smoothing (2013)

Speech signals recorded in a room are commonly degraded by reverberation. In most cases, both the speech signal and the acoustic system of the room are unknown. In this paper, a multi-microphone algorithm that simultaneously estimates the acoustic system and the clean signal is proposed. An expectation-maximization (EM) scheme is employed to iteratively obtain the maximum likelihood (ML) estimates of the acoustic parameters. In the expectation step, the Kalman smoother is applied to extract the clean signal from the data utilizing the estimated parameters. In the maximization step, the parameters are updated according to the output of the Kalman smoother. Experimental results show a significant dereverberation capabilities of the proposed algorithm with only low speech distortion.
Blood stage vaccines for<i>Plasmodium falciparum</i> (2010)

Since the recent call for a shift from malaria control to eradication, the role of asexual blood stage vaccines for falciparum malaria, which are not expected to prevent infection, has become less clear. However, blood stage antigens remain likely to be a critical component of a highly effective malaria vaccine. The inclusion of a blood stage component in a multistage malaria vaccine would not only prevent disease caused by “leaky” pre-erythrocytic immunity, but would also protect against epidemics in newly vulnerable populations. Recent clinical results of blood stage vaccine candidates have shown strain specific and partial efficacy, although no protection against clinical outcomes has been demonstrated in experimental infection or field trials to date. The current status of Plasmodium falciparum blood stage vaccine development is summarized and the potential role of these vaccines in the changed malaria landscape is discussed. Alternative preclinical and clinical development paths will speed iterative development.
Molecular characterization of infectious bronchitis virus isolates from Russia and neighbouring countries: identification of intertypic recombination in the S1 gene (2011)

Infectious bronchitis virus (IBV) isolates recovered in Russia, Ukraine, and Kazakhstan between 2007 and 2010 were subjected to molecular characterization and compared with those isolated a decade ago. The IBV genome was detected in 202 out of 605 field samples from chickens with various clinical signs. Partial sequencing of the S1 gene revealed 153 vaccine strains and 49 field isolates of several genetic groups. Massachusetts, 793/B and D274 remained the predominant IBV genotypes along with QX, whereas B1648, Italy-02, Arkansas and variants accounted for about 12% of the total number. Three IBVs contained recombinant S1 gene sequences comprising genome fragments of QX-type field isolates and vaccine strains H120 (UKR/02/2009) or 4/91 (RF/03/2010), and vaccine strains H120 and D274 (RF/01/2010). The results of the present study showed a significant decline in prevalence of variant IBVs and a further spread of QX-type isolates in commercial chicken flocks in Russia as compared with the 1998 to 2002 data.
Speed considerations and handover mechanisms in mobile personal communication systems (2002)

We construct an equivalent model of the proposed location update tree structures. In particular, we show that the performance of the queueing model is dependent on the users' population and speed. We analyze two queueing disciplines G/M/1, and G/D/1 explaining the observed phenomena analytically. Finally, we give an analytical reasoning for the observed phenomena.
A Practical Security Architecture for In-Vehicle CAN-FD (2016)

The controller area network with flexible data rate (CAN-FD) is attracting attention as the next generation of in-vehicle network technology. However, security issues have not been completely taken into account when designing CAN-FD, although every bit of information transmitted could be critical to driver safety. If we fail to solve the security vulnerabilities of CAN-FD, we cannot expect Vehicle-Information and Communications Technology (Vehicle-ICT) convergence to continue to develop. Fortunately, secure in-vehicle CAN-FD communication environments can be constructed using the larger data payload of CAN-FD. In this paper, we propose a security architecture for in-vehicle CAN-FD as a countermeasure (designed in accordance with CAN-FD specifications). We considered the characteristics of the International Organization for Standardization (ISO) 26262 Automotive Safety Integrity Level and the in-vehicle subnetwork to design a practical security architecture. We also evaluated the feasibility of the proposed security architecture using three kinds of microcontroller unit and the CANoe software. Our evaluation findings may be used as an indicator of the performance level of electronic control units for manufacturing next-generation vehicles.
Phosphino‐Aminothiazoline Platinum(II) and Platinum(II)/Gold(I) Complexes: Structural, Chemical and Vapoluminescent Properties (2007)

Phosphino-amino-thiazolines and -thiazoles can exist in solution in two tautomeric forms, in which the N-H proton involves the endo-cyclic or exo-cyclic nitrogen atom. The two tautomers show different reactivities toward alcoholysis; the imino form degrades more rapidly. Their bischelated platinum complexes were studied in the solid state by single crystal X-ray diffraction. Thus, the unique stereoelectronic features of the [Pt(PN(th))] (PN(th)=diphenylposphino-aminothiazoline) moiety were revealed. The complex cis-[Pt(PN(th))(2)] reacts with gold(I) salts to yield dimetallic compounds, the molecular structures of which have been determined by X-ray diffraction. Solid cis-[Pt(PN(th))(2)] shows vapoluminescent properties if exposed to alcohol vapors. A combined photophysical and crystallographic investigation has been carried out to clarify the unprecedented rigidochromic role of the alcohol in this phenomenon.

Time synchronization in a local area network (2004)

In this article we examine the problem of synchronizing the time-of-day clock in one node of an automation network system with a reference clock. The emphasis of this article is on switched, highly loaded networks, where unpredictable delays introduce excessive synchronization noise. PC clocks are accurate enough when connected within a network, but a new requirement is for them to be synchronized, which means that they should show the same time at the same instant. The most prominent time-synchronization method is the network time protocol proposed by Mills and Internet engineering task force group. A complete solution of the high-precision time-synchronization problem must reduce the randomness associated with the RTOS. The methods discussed in this article can help determine the frequency and time offset of a local time-of-day clock. The next challenge is to construct a local time-of-day clock and apply the synchronization information to it.
Growth-dependent alterations in production of serotype-specific and common antigen lipopolysaccharides in Pseudomonas aeruginosa PAO1 (1990)

Pseudomonas aeruginosa PAO1 was grown in various media and at different temperatures, and the heterogeneity of the extracted lipopolysaccharide (LPS) was characterized by polyacrylamide gel electrophoresis. The size distributions of the serotype-specific LPS and the common antigen LPS were analyzed on Western blots (immunoblots). Cells grown at high, near-growth-limiting temperatures, at low pH, in low concentrations of phosphate, or in high concentrations of NaCl, MgCl2, glycerol, or sucrose produced decreased amounts of the very long chain population of O-antigen LPS molecules. Lower temperatures and lowered glycerol, lowered sucrose, low sulfate, lower salt concentrations, and elevated pH did not significantly affect the level of this LPS population. The size and amount of common antigen LPS was either unaffected or increased slightly when the cells were grown under the above stress conditions. Cells grown under normal, nonstressed conditions were agglutinated only by serotype-specific antibodies. In contrast, cells grown under stress conditions, in which the long-O-polymer LPS was absent, were agglutinated by both serotype-specific and common antigen-specific antibodies. The results indicate that the long O polymers cover and mask the shorter common antigen. However, specific growth conditions limit the production of the long O polymer, allowing the exposure and reactivity of the common antigen on the cell surface.
[Multidisciplinary therapy for gastric cancer]. (2011)

Accurate preoperative staging is imperative in the treatment of gastric cancer since diseases in different stages mandate different management strategies. Multi-disciplinary therapy is important for gastric cancer. Endoscopic treatment has become the preferred treatment for patients with early gastric cancer. However, only when multiple disciplines is involved in the decision-making process, appropriate patients can be selected and benefit from the minimally invasive treatment. In China, 90% of gastric cancers are at advanced stage at diagnosis, which are associated with worse prognosis compared to early gastric cancer. The optimal treatment depends on the multi-disciplinary therapy including surgery, chemotherapy, radiotherapy, and molecular targeted therapy.

Calculating Motion Fields from Images with Two Different Exposure Times (2008)

In this paper, we present an extension to optical flow for estimating dense 2D motion fields with occlusion information. While optical flow computa- tion is based on two consecutive short-exposure images, we make also use of an additional intermediate long-exposure image. This motion-blurred in- termediate image captures scene motion directly. We introduce an image formation model that relates the long-exposure image to both short-exposure images in terms of dense 2D motion and local occlusion/disocclusion. Based on this image formation model, we describe a practical algorithm that en- ables estimating the 2D motion field of occluding and occluded regions as well as determining the instant of occlusion. Results for synthetic and real scenes demonstrate the validity of the proposed approach.
Systemic Lupus Erythematosus With Sjögren Syndrome Compared to Systemic Lupus Erythematosus Alone (2011)

There are significant variances in certain clinical and laboratory aspects between SLE-SS and SLE. This combined disease of SLE-SS has distinct features with relatively less major internal organ involvement but has more specific autoantibody profile and favorable clinical outcome.
Identification of the sequences responsible for nuclear targeting of the V protein of human parainfluenza virus type 2 (1996)

In human parainfluenza virus type 2 (hPIV-2)-infected cells, anti-phosphoprotein (P)-specific monoclonal antibody (MAb) densely stained the perinuclear regions of infected cells throughout infection, indicating that the P protein was localized exclusively in the cell cytoplasm. By contrast, antigens recognized by MAbs directed against the P-V-common domain of hPIV-2 were located predominantly in the cytoplasm, but in some hPIV-2-infected cells they were also found in the nuclei, suggesting that a fraction of hPIV-2 V protein is localized there. hPIV-2 V protein expressed from a cDNA clone was localized in the nuclei of transfected cells. By using indirect immunofluorescence analyses, we examined the intracellular localization of various sequentially deleted V proteins, to determine the nuclear localization signals (NLS) of the V protein. Two noncontiguous regions in the V protein were required for nuclear localization and retention, since deletion of these regions [region I (aa 1-46) and region II (aa 175-196)] resulted in cytoplasmic localization. Both regions resulted in nuclear localization independently. A nucleoplasmin-like NLS was identified in region II but no consensus targeting sequence could be found in region I. When NP protein was co-expressed with V protein or the N-terminal fragment (aa 1-46) of V protein, a fraction of the NP protein was translocated into cell nuclei.

Seed Priming: New Comprehensive Approaches for an Old Empirical Technique (2016)

Seed priming is a pre-sowing treatment which leads to a physiological state that enables seed to germinate more efficiently. The majority of seed treatments are based on seed imbibition allowing the seeds to go through the first reversible stage of germination but do not allow radical protrusion through the seed coat. Seeds keeping their desiccation tolerance are then dehydrated and can be stored until final sowing. During subsequent germination, primed seeds exhibit a faster and more synchronized germination and young seedlings are often more vigorous and resistant to abiotic stresses than seedlings obtained from unprimed seeds. Priming often involves soaking seed in predetermined amounts of water or limitation of the imbibition time. The imbibition rate could be somehow controlled by osmotic agents such as PEG and referred as osmopriming. Halopriming implies the use of specific salts while "hormopriming" relies on the use of plant growth regulators. Some physical treatments (UV, cold or heat,..) also provide germination improvement thus suggesting that priming effects are not necessarily related to seed imbibition. A better understanding of the metabolic events taking place during the priming treatment and the subsequent germination should help to use this simple and cheap technology in a more efficient way.
