Uneventful Spinal Anesthesia in a Patient with Precipitous Drop of Platelet Secondary to HELLP Syndrome: A Case Report and Review of Literatures  [PDF]
Joe Z Liu, Chunhua Li, Hong Wang
Open Journal of Anesthesiology (OJAnes) , 2012, DOI: 10.4236/ojanes.2012.24031
Abstract: Thrombocytopenia caused by Hemolysis, Elevated Liver enzymes and Low Platelet count (HELLP) syndrome in pre-eclampsia parturients can be associated with substantial maternal and neonatal morbidity. Data on the issue of the safety of neuraxial anesthesia with thrombocytopenia in HELLP syndrome is limited. A lower limit of 100,000 per microliter for platelet count was suggested as “safe” for performing neuraxial anesthesia, however there is no supporting data. This lower limit is challenged lately. We present a case of uneventful spinal anesthesia for urgent Cesarean section in a patient with severe pre-eclamsia, HELLP syndrome and precipitous platelet drop from 230,000 to 42,000 per microliter.
Organization Psychoanalysis: Top-Managers Satisfaction Estimation  [PDF]
E. G. Aminev, Wang Qing, Z. Khairullina
Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.28004

\"A good chief\" is one of the most important indicators of job satisfaction. However, related to the immediate supervisor, ordinary employees, and especially top-managers do not tend to show it openly. The present study confirms the effectiveness of the solution of this problem with the help of standardized psychoanalytical questionnaires where classic erotic codes are transformed into corporate ones. An integral model for calculating the level of negativity to company policy was received. Approach can be applied effectively in the corporate counseling and within individual reception program of positive psychotherapy.

Comments on "Vortex phase diagram of HgBa$_2$Ca$_2$Cu$_3$O$_{8+δ}$ thin films from magnetoresistance measurements"
Y. Z. Zhang,Z. Wang
Physics , 2005,
Abstract: We make comments on the paper presented by Kim \textit{et al.} [Phys. Rev. B \textbf{61}, 11317 (2000)]. The authors analyzed activation energies of HgBa$_2$Ca$_2$Cu$_3$O$_{8+\delta}$ thin films with a scaling relation, and defined four vortex regions for thin films. We find that the definitions of four vortex regions and the scaling relation are questionable when studying their definition of the resistivity range for thermally activated flux flow. Using the empirical activation energy form suggested by Zhang \textit{et al.} [Phys. Rev. B \textbf{71}, 052502 (2005)] for lower resistivity data, we find that the form is not only in good agreement with the resistivity $\rho(T,H)$, but also with the apparent activation energy $-\partial \ln \rho(T,H)/\partial T^{-1}$.
A remark on the Hard Lefschetz Theorem for K?hler orbifolds
Z. Z. Wang,D. Zaffran
Mathematics , 2009, DOI: 10.1090/S0002-9939-09-09848-7
Abstract: We give a proof of the hard Lefschetz theorem for orbifolds that does not involve intersection homology. This answers a question of Fulton. We use a foliated version of the hard Lefschetz theorem due to El Kacimi.
Thermal Entanglement in Ferrimagnetic Chains
Xiaoguang Wang,Z. D. Wang
Physics , 2006, DOI: 10.1103/PhysRevA.73.064302
Abstract: A formula to evaluate the entanglement in an one-dimensional ferrimagnetic system is derived. Based on the formula, we find that the thermal entanglement in a small size spin-1/2 and spin-s ferrimagnetic chain is rather robust against temperature, and the threshold temperature may be arbitrarily high when s is sufficiently large. This intriguing result answers unambiguously a fundamental question: ``can entanglement and quantum behavior in physical systems survive at arbitrary high temperatures?"
Numerical Stability Test of Neutral Delay Differential Equations
Z. H. Wang
Mathematical Problems in Engineering , 2008, DOI: 10.1155/2008/698043
Abstract: The stability of a delay differential equation can be investigated on the basis of the root location of the characteristic function. Though a number of stability criteria are available, they usually do not provide any information about the characteristic root with maximal real part, which is useful in justifying the stability and in understanding the system performances. Because the characteristic function is a transcendental function that has an infinite number of roots with no closed form, the roots can be found out numerically only. While some iterative methods work effectively in finding a root of a nonlinear equation for a properly chosen initial guess, they do not work in finding the rightmost root directly from the characteristic function. On the basis of Lambert W function, this paper presents an effective iterative algorithm for the calculation of the rightmost roots of neutral delay differential equations so that the stability of the delay equations can be determined directly, illustrated with two examples.
Bioactive Milk Peptides: Redefining the Food-Drug Interphase – Review Part 1: Antimicrobial and Immunomodulatory Peptides
SC Cheison, Z Wang
African Journal of Food, Agriculture, Nutrition and Development , 2003,
Abstract: In a three part series, we set out to summarize the data available from various research efforts into the bioactive components resulting from milk protein hydrolysis. Milk contains within itself as an original package a cache of bioactive substances that derive from its secretion. Advances in molecular understanding of processes and enzyme technology have provided new insights into products of milk protein hydrolysis, both by the enzymes and during processing. These products of food digestion and enzyme hydrolysis and processing have been shown to have antimicrobial, immunopotentiating, opioid, Angiotensin Converting-I-Enzyme inhibitory activities as well as some antithrombotic peptides. Furthermore, some peptides have been shown to have mineral binding properties owing to phosphorylation, and have been designated as caseinophosphopeptides. These are derived from such protein fractions as casein with no known bioactivity in its native form. Whether these derivatives will replace drugs entirely in the immediate future is still unclear, but the increasing appreciation of nutraceuticals will play a complementary rather than a substitutional role to the synthetic pharmacological drugs. This paper is the first part and seeks to review the bioactive milk peptides with emphasis on the immunopotentiating and antimicrobial properties including their applications in novel nutraceuticals.
RNA recognition motif (RRM)-containing proteins in Bombyx mori
L Wang, Z Zhou
African Journal of Biotechnology , 2009,
Abstract: RNA recognition motif (RRM)-containing proteins play important roles in the processing of RNA and regulation of protein synthesis. Bombyx mori is a model species of Lepidoptera whose genome sequence is available; however, its RRM-containing proteins have not been thoroughly analyzed. In this study, 134 RRM-containing protein genes in Drosophila melanogaster were used to perform BLAST search against B. mori genome- and EST databases. Results showed that 123 genes have orthologues in the B. mori genome database and 89 in B. mori EST database, indicating some of the genes were not expressed in B. mori. 23 RRM-containing protein genes that have complete open reading frame were obtained through contig assembly in B. mori EST database and then registered in NCBI. Cluster analysis showed that these 23 new proteins formed two distinct clades. Especially, TAR DNA-binding protein-43(TBPH) gene of B. mori is different from that of other species in that it does not have introns. Moreover, the length of TBPH of B. mori is much shorter than that of other species’ TBPH, suggesting that it may play some roles in emergency responses.
Using Drag to Hover
Z. Jane Wang
Physics , 2003,
Abstract: Unlike a helicopter, an insect can, in theory, use both lift and drag to stay aloft. Here we show that a dragonfly uses mostly drag to hover by employing asymmetric up and down strokes. Computations of a family of strokes further show that using drag can be as efficient as using lift at the low Reynolds number regime appropriate for insects.
