CHANGES IN THE STABILITY AND KINETIC PARAMETERS UP ON GLYCATION OF THERMOSTABLE α-AMYLASE FROM BACILLUS SUBTILIS (2010)

ABSTRACT Glycation of the thermostable α-amylase, KLE, from Bacillus subtilis occurred during incubation with maltodextrin at 95C. This was revealed by the release of 5-hydroxymethyl-2-furfuraldehyde from the acid hydrolysis of glycated KLE (gKLE), the differences in the protein band patterns on SDS and Native-PAGE, and the shifting of the pI value from the range of 5.6–6.5 to that of 5.2–6.5. After glycation, the activity of gKLE was still retained. Furthermore, gKLE was more resistant to heat and pH compared with the nonglycated enzyme. The Km, reaction rate and efficiency to convert gelatinized cornstarch into maltodextrin of KLE were remained unchanged after glycation. This was different from the result obtained for BAN, another thermostable α-amylase produced by B. amyloliquefaciens. Glycation in BAN decreased the activity in converting gelatinized cornstarch into maltodextrin. Moreover, the stability and kinetic parameters of BAN were found to be negatively affected by glycation. PRACTICAL APPLICATIONS One of the major applications of starch is for the production of glucose, either in a form of crystalline or syrup which can be further processed into high-fructose syrup. This is done by starch hydrolysis which is composed of two major enzymatic steps, i.e., liquefaction and saccharification. Liquefaction, converting gelatinized starch to maltodextrin, is carried out by the action of thermostable α-amylase, while saccharification is by glucoamylase. During the process under the conditions of high concentration of reducing sugar and high temperature, thermostable α-amylase can be glycated. This non-enzymatic process occurs when reducing sugar and free amino groups are coexisted in the system. However, the glycated enzyme was found to be more stable than the native form. Hence, industrial thermostable α-amylase with a suitable degree of glycation, can be more efficient in hydrolytic process.
Wet chemical synthesis of gold nanoparticles using silver seeds: a shape control from nanorods to hollow spherical nanoparticles (2007)

A seed-mediated method was employed here for CTAB-assisted gold nanoparticle growth 3-4 nm silver aqueous colloid was stabilized by sodium citrate and used as seed solution to initial gold particle growth. The concentration of seed solution was calculated based on its relationship with silver atom concentration and seed particle statistical mean volume. It was found that there is a maximum seed concentration of 8.57 x 10(-12) M (similar to 25 mu l 0.343 x 10(-8) M seed solution added) in 10 ml 2.5 x 10(-4) M HAuCl4 growth solution for growth of rodlike particles. Below this seed amount, the aspect ratio of nanorods could be controlled by varying the silver seed amount, i.e. nanorods with aspect ratio similar to 18.9 were obtained when the seed concentration in the growth solution was 0.343 x 10(-12) M by adding 1 mu l 0.343 x 10(-8) M silver seed solution and nanorods with aspect ratio similar to 9.69 were obtained when the seed concentration in the growth solution was 1.715 x 10(-12) M by adding similar to 25 mu l 0.343 x 10(-8) M silver seed solution. As the seed concentration in the growth solution was more than 8.58 x 10(-12) M ( 25 mu l 0.343 x 10(-8) M silver seed solution was added), there were no rodlike particles formed but spherical ones instead. These spheres were further studied by TEM and found to all be hollow structures. It was suggested that there were probably two different nucleation processes for growth of nanorods and spheres. For hollow spheres, the reaction between Ag seeds and Au ions formed hollow structures based on the Ag particle template effect. Then further growth of Au on these hollow structures produced hollow gold nanospheres. For nanorods, due to the very low concentration of silver seed ( molar ratio of Ag seed: Au = 3.426 x 10(-8)), the growth process here probably was started by silver-induced Au nucleation, in which reduction of gold ions by silver resulted in small gold clusters. These gold clusters further grew up into nanoparticles and nanorods in the presence of CTAB.
Guidelines for the design and conduct of clinical trials on dentine hypersensitivity* (1997)

Clinical trials on dentine hypersensitivity have been numerous and protocols varied. To date there is little consensus as to the conduct of studies on this poorly-understood yet common and painful dental condition. A committee of interested persons from academia and industry was convened to discuss the subject of clinical trials on dentine hypersensitivity and a consensus report is presented. A double-blind randomized parallel groups design is recommended, although cross-over designs may be used for the preliminary screening of agents. Subjects may have multiple sites scored. Sample size will be determined by estimating the variability in the study population, the effect to be detected and the power of the statistical test to be used. Subject selection is based on a clinical diagnosis of dentine hypersensitivity, excluding those with conflicting characteristics such as currently-active medical or dental therapy. The vestibular surfaces of incisors, cuspids and bicuspids are preferred as sites to be tested. A range of sensitivity levels should be included. Tactile, cold and evaporative air stimuli should be applied. Negative and benchmark controls should be incorporated. Most trials should last 8 weeks. Sensitivity may be assessed either in terms of the stimulus intensity required to evoke pain or the subjective evaluation of pain produced by a stimulus using a visual analog or other appropriate scale. The subject's overall assessment may be determined by questionnaire. Outcomes should be expressed in terms of clinically significant changes in symptoms. Follow-up evaluation is required to determine the persistence of changes. At least 2 independent trials should be conducted before a product receives approval.
Linear growth in asthmatic children (2003)

Asthma is the most frequent chronic inflammatory disease in childhood, and its prevalence has increased remarkably over the last decades. Therefore, the scientific community became interested in studying the growth of the affected children. The relationship between asthma and growth suffers the influence of the clinical picture, of therapeutics, but the different study methods make it difficult to distinguish the factors responsible for the growth retardation detected by some authors. This review has the purpose of providing an overall outlook on this matter.
A C-BiLSTM Approach to Classify Construction Accident Reports (2020)

The construction sector is widely recognized as having the most hazardous working environment among the various business sectors, and many research studies have focused on injury prevention strategies for use on construction sites. The risk-based theory emphasizes the analysis of accident causes extracted from accident reports to understand, predict, and prevent the occurrence of construction accidents. The first step in the analysis is to classify the incidents from a massive number of reports into different cause categories, a task which is usually performed on a manual basis by domain experts. The research described in this paper proposes a convolutional bidirectional long short-term memory (C-BiLSTM)-based method to automatically classify construction accident reports. The proposed approach was applied on a dataset of construction accident narratives obtained from the Occupational Safety and Health Administration website, and the results indicate that this model performs better than some of the classic machine learning models commonly used in classification tasks, including support vector machine (SVM), naïve Bayes (NB), and logistic regression (LR). The results of this study can help safety managers to develop risk management strategies.
An effort to test the embryotoxicity of benzene, toluene, xylene, and formaldehyde to murine embryonic stem cells using airborne exposure technique (2009)

Benzene, toluene, xylene, and formaldehyde are well-known indoor air pollutants, especially after house decoration. They are also common pollutants in the working places of the plastic industry, chemical industry, and leather industry. It has been reported that these pollutants cause people to be irritated, sick, experience a headache, and be dizzy. They also have the potential to induce asthma, aplastic anemia, and leukemia, even cause abortion or fetus malformation in humans. In this study, the airborne toxicity of benzene, toluene, xylene, and formaldehyde to murine embryonic stem cells (mES cells) were tested using airborne exposure technique to evaluate the mES cell airborne exposure model on embryotoxicity prediction. Briefly, mES cells were cultured on Transwell inserts and were exposed to an airborne surrounding of test chemicals in a chamber for 1 h at 37 degrees C. Cytotoxicity was determined using the MTT assay after further culture for 18 h at 37 degrees C in normal medium. The airborne IC(50) (50% inhibition concentration) of benzene, toluene, xylene, and formaldehyde derived from the fitted dose-response curves were 17,400 +/- 1290, 16,000 +/- 250, 4680 +/- 500, and 620 +/- 310 ppm, respectively. Formaldehyde was found to be the compound most toxic to mES cells compared to benzene homologues. The toxicity data had good correlation with the in vivo data. The results showed that the mES airborne exposure model may be used to predict embryotoxicity of volatile organic compounds.
Display of Antibody Chains on Filamentous Bacteriophage (1998)

The construction of very large combinatorial libraries whereby antigen-binding functional domains of antibodies (Abs) are cloned and displayed on the surface of bacteriophage is proving to be a powerful technology in providing reagents for immunotherapy. Combinations of randomly assembled pairs of immunoglobulin heavy (H) and light (L) chain genes are cloned and expressed as fusions of bacteriophage coat proteins, allowing the bacteriophage expressing them to be selected by methods analogous to affinity chromatography. Purified phage can then be used for the production of large amounts of the pure antibody in a soluble form. Although phage-derived antibodies lack the effector functions of the parent antibodies since they have no Fc regions, these can subsequently be engineered into place or substituted with others, such as a toxin, with relative ease if required. Various antigen-recognition regions of the Ab can be cloned and selected, including: 1. Fv fragments that are noncovalently associated heterodimers of the heavy variable (VH) and light variable (VL) domains 2. Single-chain Fv fragments (scFv) consisting of VH and VL regions linked by a flexible peptide 3. Fabs that are noncovalently associated VH-CH and VL-CL pairings of Ab chains.
Some 4.4′‐diformyl‐α,ω‐diphenoxyalkanes and their derivatives (1947)

Abstract Some 4,4′‐diformyl‐α,ω‐diphenoxyalkanes have been prepared by reacting the sodium salt of p‐hydroxybenzaldehyde with α,ω‐dibromoalkanes. These compounds were oxidised by alkaline potassium permanganate solution to the corresponding α,ω‐diphenoxyalkane‐4,4′‐dicarboxylic acids. The diformyl compounds were reacted with malonic acid yielding acrylic acid derivatives which have the melting‐point characteristics of mesomorphic substances. Hippuric acid has been shown to condense readily with the diformyl products yielding mono‐ and bis‐azlactones.
Reliability for manufacturing on 45nm logic technology with high-k + metal gate transistors and Pb-free packaging (2009)

This paper addresses several key aspects of integrated reliability for the Intel 45 nm logic technology with high-K metal gate (HK + MG) transistors and Pb-free packaging. Significant changes in process architecture and materials were introduced and careful integration and manufacturing innovations were needed to meet historical expectations for transistor, defect, and package reliability. Furthermore the stability of intrinsic and defect reliability performance needed to be demonstrated. Highly accelerated TDDB and bias temperature instability (BTI) tests were implemented to enable very high sampling rates, establishing stable transistor reliability in high manufacturing volumes. Integrated product defect reliability results are presented showing that the historical correlation to yield defect density for stable manufacturing processes is maintained on this generation into an even lower fail rate regime. Similarly, volume package reliability monitor data are shown validating thermo-mechanical stability of the 1st level Pb-free package interconnect.

Estimation of Q-factors and resonant frequencies (2003)

We estimate the quality factor Q and resonant frequency f/sub 0/ of a microwave cavity based on observations of a resonance curve on an equally spaced frequency grid. The observed resonance curve is the squared magnitude of an observed complex scattering parameter. We characterize the variance of the additive noise in the observed resonance curve parametrically. Based on this noise characterization, we estimate Q and f/sub 0/ and other associated model parameters using the method of weighted least squares (WLS). Based on asymptotic statistical theory, we also estimate the one-sigma uncertainty of Q and f/sub 0/. In a simulation study, the WLS method outperforms the 3-dB method and the Estin method. For the case of measured resonances, we show that the WLS method yields the most precise estimates for the resonant frequency and quality factor, especially for resonances that are undercoupled. Given that the resonance curve is sampled at a fixed number of equally spaced frequencies in the neighborhood of the resonant frequency, we determine the optimal frequency spacing in order to minimize the asymptotic standard deviation of the estimate of either Q or f/sub 0/.
<title>Developments In Mode-Locked Lasers And Their Applications</title> (1982)

This paper reports a potpourri of recent results on mode, locking (primarily of Nd:YAG lasers and phase conjugate resonators) and on mode-locked pulse applications (to photo-acoustic spectroscopy and to laser annealing) from the author's group in the Edward L. Ginzton Laboratory at Stanford University.
Endothelial cell membranes contain podocalyxin--the major sialoprotein of visceral glomerular epithelial cells. (1986)

Podocalyxin is the major sialoprotein in the glycocalyx of glomerular podocytes. Here we report on its extraglomerular localization, using a monospecific antibody which was obtained by affinity purification of IgG on nitrocellulose transfers of glomerular podocalyxin. By indirect immunofluorescence, podocalyxin was found in the blood vessels of several organs (lung, heart, kidney, small intestine, brain, pancreas, aorta, the periportal blood vessels in liver, and the central arteries of follicles of the spleen, but not in the endothelia that line the sinusoids of the latter organs). By immunoelectron microscopy--using immunogold conjugates in diffusion ("pre-embedding") and surface ("postembedding") procedures--podocalyxin was localized on the luminal membrane domain of endothelial cells, in a patchy distribution. The presence of podocalyxin was confirmed in SDS extracts of lung tissue by immunoblotting. We conclude that (a) podocalyxin is a widespread component of endothelial plasma membranes, (b) it is restricted to the luminal membrane domain, and (c) it is distributed unevenly on the endothelial cell surface.
Performance comparison of several feature selection methods based on node pruning in handwritten character recognition (2002)

The paper presents a performance comparison of several feature selection methods based on neural network node pruning. Assuming the features are extracted and presented as the inputs of a 3 layered perceptron classifier, we apply the five feature selection methods before/during/after neural network training in order to prune only input nodes of the neural network. Four of them are node pruning methods such as node saliency method, node sensitivity method, and two interactive pruning methods using different contribution measures. The last one is a statistical method based on principle component analysis (PCA). The first two of them prune input nodes during training whereas the last three do before/after network training. For gradient and upper down, left right hole concavity features, we perform several experiments of handwritten English alphabet and digit recognition with/without pruning using the five feature selection algorithms, respectively. The experimental results show that node saliency method outperforms the others.
Complications of needle thoracostomy: A comprehensive clinical review (2015)

Needle thoracostomy (NT) is a valuable adjunct in the management of tension pneumothorax (tPTX), a life-threatening condition encountered mainly in trauma and critical care environments. Most commonly, needle thoracostomies are used in the prehospital setting and during acute trauma resuscitation to temporize the affected individuals prior to the placement of definitive tube thoracostomy (TT). Because it is both an invasive and emergent maneuver, NT can be associated with a number of potential complications, some of which may be life-threatening. Due to relatively common use of this procedure, it is important that healthcare providers are familiar, and ready to deal with, potential complications of NT.
Fastcrypto: Parallel AES Pipelines Extension for General-Purpose Processors (2009)

In cryptography, the advanced encryption standard (AES) is an encryption standard issued as FIPS by NIST as a successor to data encryption standard (DES) algorithm. The applications of the AES are wide including any sensitive data that requires cryptographic protection before communication or storage. This paper proposes extending general-purpose processors with crypto coprocessor based on decoupled architectures. The extended coprocessor splits an encryption/decryption instruction into memory (load/store) and computation (encryption/decryption) portions (pseudo instructions). Loading/storing and encrypting/decrypting data are performed in parallel and communicated through architectural queues. The computational unit includes parallel AES pipelines for fast encrypting/decrypting data. On four parallel AES pipelines, our results show a performance of 222 Gigabits per second.
Factors which affect erythropoiesis in partially nephrectomized and sham-operated rats (1976)

Current concepts of the pathogenesis of anemia in uremic animals are derived mainly from the results of studies performed either in vitro or in bilaterally nephrectomized animals. These data may not be applicable to the situation which exists in more chronically uremic animals. In 1932, Chanutin and Ferris showed that removal of five-sixths of the renal mass caused rats to become uremic and to remain so for a prolonged period of time. Rats made uremic in this manner were utilized as models for studying the pathogenesis of the anemia of uremia. Removeal of five-sixths of the renal mass of rats caused their BUNs to rise to over 100 mg/100 ml and to remain at this level for over 3 wk. The hematocrits of these uremic rats fell from 42% to approximately 30% in 3 wk. Erythropoietin (Ep) production immediately fell to a barely detectable level postoperatively and did not increase significantly in 3 wk, although the renal remnant hypertrophied. Extrarenal Ep production also remained at a low level and did not increase during the 3-wk observation period. The response of plethoric uremic rats to 2 units of Ep was as great (in some experiments greater) as that of sham- operated ones. A surprising finding was that plethoric uremic rats, injected with saline rather than with Ep, incorporated more 59Fe into their red blood cells than did sham-operated ones. This finding suggested that in uremic rats erythropoiesis was less markedly suppressed by plethora than it was in non-uremic rats.
