Effects of Tsetse (Glossina morsitans morsitans Westw.) (Diptera: Glossinidae) Salivary Gland Homogenate on Coagulation and Fibrinolysis (1979)

The saliva of the tsetse, Glossina morsitans morsitans Westwood, has antithrombin anticoagulant activity and inhibits thrombin's esterolytic activity. It has no other detectable anticoagulant properties. The anticoagulant elutes in a single peak on Sephadex fraction, is immediately acting, heat and storage stable, and has a molecular weight of 11-13,000. Unlike heparin it is not neutralized by protamine sulphate or toluidine blue and does not require the co-factor, antithrombin III, for optimal anticoagulant activity. It has similar properties to hirudin, but does not elute with a protein peak upon Sephadex fractionation and has a slightly different molecular weight. Salivary gland homogenates contained neither a plasminogen activator nor fibrinolytic activity. The sera of rabbits used to maintain tsetses, which contained precipitating antibodies against saliva, did not neutralize the salivary anticoagulant in vitro. The properties of this anticoagulant suggest that it might be a potentially useful antithrombotic agent in man.

Surface Modification of Ceramic‐Supported Polyethersulfone Membranes by Interfacial Polymerization for Reduced Membrane Fouling (2005)

Abstract Summary: This study reports a simple and effective route for the hydrophilic surface modification of ceramic‐supported polyethersulfone membranes by synthesizing a poly(vinyl alcohol)/polyamide composite thin surface layer with an interfacial polymerization method. The fabricated membranes were characterized with XPS, SEM, and contact angle measurements, and the effects of hydrophilic surface modification on the membrane flux and oil rejection in the treatment of oil‐in‐water (O/W) microemulsions were experimentally studied. All the characterizations and filtration results showed that, the hydrophilic surface modification was achieved successfully and consequently reduced the membrane fouling effectively. The presented route is valuable for developing robust membranes with a low level of membrane fouling in the separation of O/W microemulsions. Hydrophilic surface modification resulted in enhanced membrane performance. magnified image Hydrophilic surface modification resulted in enhanced membrane performance.

[Celecoxib increased cellular ATRA sensitivity of human colon cancer cell lines through COX-2-independent mechanisms]. (2009)

Retinoid resistance has limited clinical activity of retinoids as differentiation-inducing and apoptosis-inducing drugs. The present study was designed to investigate whether celecoxib (selective COX-2 inhibitor) has effects on cellular retinoid sensitivity of human colon cancer cell lines and its possible mechanism. Cell viability was measured by MTT assay. Apoptosis was detected by Annexin-V/PI staining and flow cytometry assay. PGE2 production was measured by ELISA assay. Expression of RARbeta was assayed by Western blotting. The results showed that celecoxib enhanced the inhibitory effect of ATRA in both COX-2 high-expressing HT-29 and COX-2 low-expressing SW480 cell lines. Further study showed the ATRA and celecoxib combination induced greater apoptosis, and the addition of PGE2 did not affect the number of apoptotic cells induced by the combination. Moreover, NS398 (another selective COX-2 inhibitor) did not affect the inhibitory effects of ATRA on both cell lines. Western blotting showed that the expression of RARbeta in HT-29 cell lines increased in celecoxib group and combination group. And the addition of PGE2 did not affect the expression of RARbeta induced by celecoxib either. In conclusion, celecoxib increased expression of RARbeta and cellular ATRA sensitivity through COX-2-independent mechanisms, which may provide a potential strategy for combination therapy.

Ferroelectric liquid crystal behavior in platinum orthometallated complexes (2002)

Di-μ-chloro-bis[(η3-2-methylallyl)platinum] reacts with chiral imines, p-R1C6H4CHNC6H4OR2-p [HL*; with R1, R2, or both equal to either (R)- or (S)-1-methylheptyl], to yield the C,N-cyclometallated platinum(II) compounds [Pt2(μ-Cl)2(L*)2] (2). Treatment of 2 with Tl[(p-H21C10OC6H4CO)2CH] produces mononuclear orthoplatinated complexes (3) incorporating a β-diketonate. Both complexes 2 and 3 are mesomorphic materials that display smectic A (SmA) and chiral smectic C (SmC*) phases. Their mesogenic properties are compared with those of their palladium analogues, reported previously. The platinum complexes show somewhat more stable mesophases. A study of the ferroelectric properties of compounds 2 and 3 has been performed.
Trajectory Planning Approach of Mobile Robot Dynamic Obstacle Avoidance with Multiple Constraints (2021)

This paper proposes a novel trajectory planning approach based on time elastic band to solve the problem of dynamic obstacle avoidance of mobile robot. Uncertain factors in the scenario need to be considered in trajectory planning. Thus, this approach includes multiple constraints, such as robot motion speed, motion state, and obstacles. First, to solve the optimal speed of the mobile robot, the workspace potential field must be established, and environmental information should be obtained to constrain the robot speed. Second, a costmap needs to be established to detect dynamic obstacles, and obstacle avoidance strategies based on the relative motion relationship between dynamic obstacles and the robot should be proposed to realize dynamic obstacle avoidance. Finally, by combining multiple constraints, the collision-free trajectory planning from the start point to the target point is completed, and the mobile robot realizes collision-free smooth motion. Experimental results show that this approach has satisfactory obstacle avoidance planning effects and superior kinematics characteristics and improves the comfort and safety of the mobile robot.
Histone Methyltransferase Gene <i>SETD2</i> Is a Novel Tumor Suppressor Gene in Clear Cell Renal Cell Carcinoma (2010)

Sporadic clear cell renal cell carcinoma (cRCC) is genetically characterized by the recurrent loss of the short arm of chromosome 3, with a hotspot for copy number loss in the 3p21 region. We applied a method called "gene identification by nonsense-mediated mRNA decay inhibition" to a panel of 10 cRCC cell lines with 3p21 copy number loss to identify biallelic inactivated genes located at 3p21. This revealed inactivation of the histone methyltransferase gene SETD2, located on 3p21.31, as a common event in cRCC cells. SETD2 is nonredundantly responsible for trimethylation of the histone mark H3K36. Consistent with this function, we observed loss or a decrease of H3K36me3 in 7 out of the 10 cRCC cell lines. Identification of missense mutations in 2 out of 10 primary cRCC tumor samples added support to the involvement of loss of SETD2 function in the development of cRCC tumors.
A Media-Based Traceroute Function for the Session Initiation Protocol (SIP) (2014)

SIP already provides the ability to perform hop-by-hop traceroute for
SIP messages using the Max-Forwards header field to determine the
reachability path of requests to a target. A mechanism for media-
loopback calls has also been defined separately, which enables test
calls to be generated that result in media being looped back to the
originator. This document describes a means of performing hop-by-hop
traceroute-style test calls using the media-loopback mechanism to test
the media path when SIP sessions go through media-relaying back-to-
back user agents (B2BUAs).
Catalyst-free growth of nanographene films on various substrates (2010)

We have developed a new method to grow uniform graphene films directly on various substrates, such as insulators, semiconductors, and even metals, without using any catalyst. The growth was carried out using a remote plasma enhancement chemical vapor deposition (r-PECVD) system at relatively low temperatures, enabling the deposition of graphene films up to 4-inch wafer scale. Scanning tunneling microscopy (STM) confirmed that the films are made up of nanocrystalline graphene particles of tens of nanometers in lateral size. The growth mechanism for the nanographene is analogous to that for diamond grown by PECVD methods, in spite of sp2 carbon atoms being formed in the case of graphene rather than sp3 carbon atoms as in diamond. This growth approach is simple, low-cost, and scalable, and might have potential applications in fields such as thin film resistors, gas sensors, electrode materials, and transparent conductive films.
GENETICS AND HUNGER (1974)

HE most surprising fact about agriculture is that it sometimes feeds people, Tthat hunger is not more widespread than it is. This is surprising because in most of the world today food production is not engaged in to feed people, food does not flow from well-fed areas to hungry areas; fluctuations in food production do not follow changing needs. EHHLICH and EHRLICH (1970) have pointed out that there is a net flow of protein from “developing” to affluent countries. In years of bumper harvests such as 1969, the price of grain falls to the point where it can be used to feed cattle and be converted to animal protein for the well-fed. In bad years prices rise, black marketeers buy up supplies, and the inequality in distribution is accentuated. Further we can assert that agricultural programs and agricultural research are not usually aimed at feeding people either. The former are determined in order to stabilize the balance of payments (DALRYMPLE and JONES 1973) or to obtain natural gas, or as in the fire ant control program to show that the Department of Agriculture loves farmers. Levels of production are set at international confrontations of producers and consumer nations. Departments of Agriculture usually function to serve the farmers as a political consistency, and this generally means the richer farmers. The main effort of agricultural research is the production of marketable commodities that can be sold to farmers-insecticides, fertilizers, or machines mostly. The feeding of people is a by-product of all this, predictable insofar as food is edible, but a by-product nonetheless and very uneven across space, time, and social class. Therefore, our professional pride notwithstanding, agricultural genetics is neither the key to human happiness nor survival that we are expected to claim at international symposia. Nor is there the direct relation between plant or animal breeding and human hunger that we would expect when we resort to the linear syllogism: food relieves hunger, crops yield food, therefore improving yields reduces hunger. An agricultural science which really serves people’s needs must have a broader base than plant biology and a more complex view of the world. But if all this is true, if food as a commodity prevails over food as nutrition, if land as investment prevails over land as productive soil and science as product development predominates over science as understanding aimed at freedom from want, if the locus of hunger is in political economy rather than entomology, why do we bother to look at genetics? I think there are several good reasons:
Midodrine in neurally mediated syncope: A double‐blind, randomized, crossover study (2002)

Neurally mediated syncope is the most frequent cause of syncope in patients without structural heart disease. Its most common trigger is a reduction in venous return to the heart due to excessive venous pooling in the legs. We conducted a double-blind, randomized, crossover trial to investigate the efficacy of midodrine, a selective alpha-1 adrenergic agonist that decreases venous capacitance, in preventing neurally mediated syncope triggered by passive head-up tilt. Twelve patients with history of recurrent neurally mediated syncope, which was reproduced during head-up tilt, were randomized to receive a nonpressor dose of midodrine (5mg) or placebo on day 1 and the opposite on day 3. One hour after drug or placebo administration, patients underwent 60-degree head-up tilt lasting 40 minutes (unless hypotension or bradycardia developed first). In the supine position, midodrine produced no significant change in blood pressure or heart rate. The responses to head-up tilt were significantly different on the midodrine and the placebo day: on the placebo day, 67% (8/12) of the subjects suffered neurally mediated syncope, whereas only 17% (2/12) of the subjects developed neurally mediated syncope on the midodrine day (p < 0.02). These results indicate that midodrine significantly improves orthostatic tolerance during head-up tilt in patients with recurrent neurally mediated syncope.
Nanofibrous scaffold prepared by electrospinning of poly(vinyl alcohol)/gelatin aqueous solutions (2011)

Abstract A series of nanofibrous scaffolds were prepared by electrospinning of poly(vinyl alcohol) (PVA)/gelatin aqueous solution. PVA and gelatin was dissolved in pure water and blended in full range, then being electrospun to prepared nanofibers, followed by being crosslinked with glutaraldehyde vapor and heat treatment to form nanofibrous scaffold. Field emission scanning electron microscope (FESEM) images of the nanofibers manifested that the fiber average diameters decreased from 290 to 90 nm with the increasing of gelatin. I n vitro degradation rates of the nanofibers were also correlated with the composition and physical properties of electrospinning solutions. Cytocompatibility of the scaffolds was evaluated by cells morphology and MTT assay. The FESEM images revealed that NIH 3T3 fibroblasts spread and elongated actively on the scaffolds with spindle‐like and star‐type shape. The results of cell attachment and proliferation on the nanofibrous scaffolds suggested that the cytotoxicity of all samples are grade 1 or grade 0, indicating that the material had sound biosafety as biomaterials. Compared with pure PVA and gelatin scaffolds, the hybrid ones possess improved biocompatibility and controllability. These results indicate that the PVA/gelatin nanofibrous have potential as skin scaffolds or wound dressing. © 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Electrical Coupling Promotes Fidelity of Responses in the Networks of Model Neurons (2009)

We consider an integrate-and-fire element subject to randomly perturbed synaptic input and an electrically coupled ensemble of such elements. The latter is interpreted as either a model of electrically coupled population of neurons or a multicompartment model of a dendrite. Random fluctuations blur the input signal and cause false responses in the system dynamics. For instance, under the influence of noise, the system may respond with an action potential to a subthreshold stimulus. We show that the responses of the elements within the network are more reliable than the responses of the same elements in isolation. Specifically, we show that the variances of the stochastic processes generated by the coupled model can be made arbitrarily small (i.e., the network responses can be made arbitrarily accurate) by increasing the number of elements in the network and the strength of electrical coupling. Our results suggest that the organization of cells in electrically coupled groups on the network level, or the dendritic morphology on the cellular level, may be involved in the filtering noise and therefore may play an important role in the information processing mechanisms operating on the network or cellular level respectively.
QoS-Aware Web Service Composition Based on SLA (2008)

In service-oriented architecture, functionally equivalent Web services with different quality can be selected to put together to accomplish a task dynamically. Web service should be chosen by requestors based on their requirements. SLA can satisfy the requirement of requester seamlessly, and QoS-aware Web service composition based on SLA can implement the automation of Web service management, thus it will become one of the directions of future Web service dynamical composition. In this paper, the QoS-aware Web service composition is proposed. The relationship between SLA vector space and QoS of Web service composition is build by functional analysis.
