Cardiac Resuscitation (1962)

THE technics of external electric cardiac stimulation1 and defibrillation2 have found considerable application in cardiac emergencies. Most recently the technic of external cardiac massage has also been advocated for use in similar emergencies.3 , 4 In the following case all three procedures were employed, and all three were apparently indispensable for the successful cardiac resuscitation.Case ReportH.M. (B.I.H. M141204), a previously well 60-year-old postal worker, entered the Emergency Ward on November 20, 1961, with a chief complaint of chest pain of 3 hours' duration.When first seen, he was sweating slightly, the lungs were clear, the heart was not enlarged, and . . .
Comparison of the Binding of Penicillin G to Staphylococcal L-Form and Its Parent Strain Membranes (1976)

The binding of penicillin G to a stable L-form from Staphylococcus aureus followed saturation-type kinetics with saturation achieved at 0.75 nmol/ml, the same as with its parent strain.
A new subgroup approach to the thermo-dynamic (Landau) theory of continuous phase transitions in structurally complex crystals (1977)

Abstract A brief review is given of the usual Landau theory. In the present work it is assumed that the free energy functional of a structurally complex crystal is a sum of sublattice free energies plus a small interaction term. The analysis is then reformulated in terms of the relevant effective sub-space groups of the sublattices: the order parameters, the subduction criteria, and the other conditions on admissible transitions are related to the effective subspace groups. It is found that a transition can be “nearly second order,” i.e. second order with respect to the subgroup but really first order with respect to the actual full space group for similar order parameters. The approach is illustrated on the A-15 compounds especially the transitions O h 3 → D4 5 and O h 3 → C7 4v produced by “strain-like” order parameters.

On the Goldstein-Levitin-Polyak gradient projection method (1976)

This paper considers some aspects of a gradient projection method proposed by Goldstein [1], Levitin and Polyak [3], and more recently, in a less general context, by McCormick [10]. We propose and analyze some convergent step-size rules to be used in conjunction with the method. These rules are similar in spirit to the efficient Armijo rule for the method of steepest descent and under mild assumptions they have the desirable property that they identify the set of active inequality constraints in a finite number of iterations. As a result the method may be converted towards the end of the process to a conjugate direction, quasi-Newton or Newton's method, and achieve the attendant superlinear convergence rate. As an example we propose some quadratically convergent combinations of the method with Newton's method. Such combined methods appear to be very efficient for large-scale problems with many simple constraints such as those often appearing in optimal control.
Meta-Substituted Aryl(thio)ethers as Potent Partial Agonists (or Antagonists) for the Histamine H<sub>3</sub>Receptor Lacking a Nitrogen Atom in the Side Chain (2004)

4-(3-Aryloxypropyl)-1H-imidazoles, which possess a meta-positioned substituent in the aryl ring, have been synthesized and tested for activity at histamine H(3) receptors. The compounds having a CN, Me, or Br substituent were found to be antagonists, whereas CF(3), Et, i-Pr, t-Bu, COCH(3), or NO(2) substituents remarkably afforded partial agonists when tested in vitro on rat cerebral cortex synaptosomes for inhibition of [(3)H]histamine release. The compounds were also active in vivo, and furthermore, the CF(3)-substituted compound trifluproxim (UCL 1470, 7) acted as a potent full agonist in vivo, having ED(50) = 0.6 +/- 0.3 mg/kg per os in mice for inhibition of brain N(tau)-methylhistamine formation. Related structures have also been investigated; homologues 4-[4-(3-(trifluoromethyl)phenoxy)butyl]-1H-imidazole and 4-[2-(3-(trifluoromethyl)phenylthio)ethyl]-1H-imidazole are shown to be partial agonists, whereas the O isostere 4-[2-(3-(trifluoromethyl)phenoxy)ethyl]-1H-imidazole is an antagonist as is the S homologue 4-[3-(3-(trifluoromethyl)phenylthio)propyl]-1H-imidazole and its CH(2) isostere 4-[4-(3-(trifluoromethyl)phenyl)butyl]-1H-imidazole.

A triosephosphate isomerase(Tpi) gene of honey bee(Apis mellifera) was cloned by electronic cloning method based on the EST sequences from UniGene of NCBI,its sequence was identified by PCR and predicted by bio-informatics method.The results were as follows: the gene full length was 1768 bp;the gene had a complete open reading frame(ORF),which encoded the protein with 247 amino acids,whose nucleotide sequence had high conservation compared with the protein sequences of triosephosphate isomerase in fruit fly(Dorsophila melanogaster),silkworm(Bombyx mori),mealworm(Tenebrio molito),malaria mosquito(Anopheles gambiae) and tobacco budworm(Heliothis virescens).
IRRADIATION AND STORAGE EFFECTS ON AROMA AND COLOR OF RAW BEEF PATTIES IN ANAEROBIC OR AEROBIC PACKAGING<sup>1</sup> (2000)

ABSTRACT Effects of irradiation (2 kGy) of ground beef from trimmings aged 3, 6, or 9 days postmortem (PM) and packaged aerobically or anaerobically on lean color and aroma were investigated. Irradiation increased off‐odors and reduced color scores and Hunter a* (redness) and b* (yellowness) values (P < 0.05). Aerobic packaging increased (P < 0.05) off‐odors and Hunter L* (lightness) and b* values while reducing color scores and a* values. Irradiated patties made from trimmings of the shortest aged meat, 3‐days, had higher color scores and a* values, compared to irradiated samples aged 6‐ and 9‐days PM (P < 0.05). Irradiated patties packaged aerobically had more (P < 0.05) off‐odors, hue angle and L* and b* values and lower color scores and a* values when compared to irradiated anaerobic patties. Thus, irradiated beef patties should be made of short aged trimmings and anaerobically packaged to prevent discoloration and off‐odors.
IMPROVEMENTS TO THE METHOD OF SEPARATION OF RARE EARTHS BY ION EXCHANGE (1953)

The pollution load of nitrogen and phosphorus in pollutants entering the sea is high, which seriously affects the water quality of coastal water. It is necessary to strengthen land-sea coordination. However, affected by the seawater encroachment, the salt and alkali content of the water in the estuary area is high and the variation range is large, which leads to difficulty in plant growth. The ability of plants to remove nitrogen and phosphorus is reduced. How to improve the survival ability of plants is an urgent problem to be solved. In this study, the addition of appropriate concentrations of Ca<sup>2+</sup> and K<sup>+</sup> can improve the salinity tolerance of plants and reduce the risk of eutrophication. The results showed that under the condition of pH 8 and salinity 20‰, the removal efficiency of total nitrogen and total phosphorus was the highest in the hydroponic experiment with exogenous Ca<sup>2+</sup> and K<sup>+</sup> concentrations of 8mmol·L<sup>-1</sup> and 10mmol·L<sup>-1</sup> respectively, which were 1.53-1.87 times those in the control group. At this time, the growth rate of <i>Suaeda salsa</i> was the best, and the maximum relative growth rates (RGR) were 2.4 times and 2.0 times that of the control group, respectively. The remission effect of Ca<sup>2+</sup> was greater than that of K<sup>+</sup> at the same concentration. The mechanism by which exogenous Ca<sup>2+</sup> and K<sup>+</sup>improve the salt-alkali tolerance ability of <i>Suaeda salsa</i> was mainly manifested as improving osmotic regulation ability. In the aspect of inorganic osmotic regulation, exogenous ions improved the water-holding capacity of the plant, among which the correlation coefficients of inorganic ion content and water content in leaves and roots were all above 0.966. In terms of organic osmotic regulation, exogenous Ca<sup>2+</sup> and K<sup>+</sup> all promoted the accumulation of small molecular organic compounds such as betaine in <i>Suaeda salsa</i>, and alleviated plasma membrane peroxidation in leaves. Among them, the largest reductions of malondialdehyde content in leaves were 72.9% and 61.7%, respectively. Therefore, exogenous Ca<sup>2+</sup> and K<sup>+</sup>can enhance the osmotic adjustment ability and promote the growth of <i>Suaeda salsa</i>, thereby improving the removal rate of nitrogen and phosphorus. The results provide a theoretical basis for improving the water purification effect and reducing eutrophication risk in coastal waters.

Up‐regulation of cathepsin X in <i>Helicobacter pylori</i> gastritis and gastric cancer (2005)

Recently, we identified increased cathepsin X expression in H. pylori-infected gastric mucosa. Here, we describe further up-regulation in gastric cancer and report on the role of inflammatory cytokines required for cathepsin X up-regulation in H. pylori-infected gastric mucosa, as well as on consequences for cellular invasion. Biopsy specimens were taken from the antrum, corpus and cardia of H. pylori-infected and non-infected patients. Gastric cancer samples were obtained from patients undergoing gastric surgery. Cathepsin X was detected in gastric mucosa by quantitative real-time RT-PCR, western blotting and immunohistochemistry. Induction of cathepsin X expression in epithelial and inflammatory cells caused by H. pylori infection was tested in in vitro contact and non-contact co-cultures of AGS cells and monocytic cells. Patients with H. pylori gastritis showed significantly higher cathepsin X mRNA (2.5-fold) and protein (1.6-fold) expression than H. pylori-negative patients. Cathepsin X was also up-regulated in gastric cancer (3-12-fold) compared to non-neoplastic mucosa. Cathepsin X was predominantly expressed by macrophages in the mucosal stroma and in glands of the antral mucosa. In addition, tumour cells stained for cathepsin X in 26 (68%) patients with gastric carcinoma. In general, staining was significantly more common (20 vs. 6 patients) and more intense (3.55 vs. 0.83) in intestinal type gastric cancer than in the diffuse type. In vitro cell culture experiments revealed that intercellular signalling between pathogenicity island (PAI)-positive H. pylori-infected epithelial cells and macrophages via soluble factors in the culture medium seems to be responsible for increased expression of cathepsin X in monocytes. Using antisense oligonucleotides, cathepsin X up-regulation was directly associated with higher invasiveness in vitro. Although no correlation of cathepsin X expression and TNM stage was found, our study demonstrates that cathepsin X plays a role not only in the chronic inflammation of gastric mucosa but also in the tumourigenesis of gastric cancer.
A New Measurement Technique of Low-Level Strain Retardation in Optoelectronic Materials (2006)

This paper introduces the principles and execution of a new technique for low-level strain retardation measurement, which requires only three phase-stepping images, with precision. It then discusses the potential of this new technique for improving automated photoelasticity. To verify the new technique experimentally, a precise crystal wave plate of having low-level retardation was used as a specimen. The tolerance in retardation was 10.0plusmn4.7 nanometers. The measurements of the retardation with standard deviation using the new technique were also found to be 10.0plusmn4.7 nanometers, which agreed well in spite of low-level amount of retardation. Moreover, the measured offsets of the angular orientation were found to be -0.05plusmn4.46 degrees with standard deviation for angular position of the rotation stage for the specimen. The instrument described in this paper includes beam splitters to measure the influence on these measurements to develop the instrument into an automated one in future research. Finally, it is suggested that an automated photoelasticity will now be possible within an error of around plusmn3nm in retardation and around plusmn5degrees in its related orientation
Experience With 208 Resections for Intraductal Papillary Mucinous Neoplasm of the Pancreas (2008)

Patients with main duct IPMN or high-risk branch duct IPMN should be considered for targeted pancreatectomy. Invasive IPMN behaves as aggressively as ductal adenocarcinoma, but resection seems to provide the only potential for cure. Even with negative resection margins, the pancreatic remnant harbors a risk of recurrence and, thus, careful long-term surveillance is warranted.
Circadian Rhythms of Human Pineal Melatonin, Related Indoles, and Beta Adrenoreceptors: Post‐Mortem Evaluation (1990)

Human pineal glands obtained from 77 post-mortem sources from various age groups and times of death were used to examine the 24-hour cycle of serotonin (5-HT), melatonin, N-acetylserotonin (NAS), and beta adrenoceptor density. Pineal glands were divided sagittally and a single half was used to measure 5-HT, NAS, and melatonin concentrations, while the remaining half from the same gland was employed to assess changes in the density of beta adrenoceptors on partially purified membranes. The results show that density of pineal beta adrenoceptors was relatively constant between midnight and 18.00 h and became significantly higher between 18.00 and 20.00 h as measured by ligand saturation binding experiments using (125-I) iodocyanopindolol. The receptor affinity of all of the samples assayed remained in relatively narrow range near 58 pM and only changes in the relative receptor density were apparent. The up-regulation of receptors coincided with an increase in the concentration of 5-HT that began to rise between 16.00 and 20.00 h and became maximal between 20.00 and midnight. NAS, the immediate precursor of melatonin, was also at maximal levels between 20.00 h and midnight. Both 5-HT and NAS began declining after midnight and this change corresponded to the maximal pineal gland concentration of melatonin between midnight and 4.00 h. It is therefore suggested that the up-regulation of beta adrenoceptors noted during the late afternoon and early evening hours corresponds to the increased synthesis of 5-HT and the subsequent conversion to NAS. These events are followed by the highest accumulation of melatonin after midnight and represent the synthesis of melatonin from its precursor NAS in a sequential pattern.
Control of a six‐axis pneumatic robot (2002)

Abstract The article presents a control system for a six‐degree of freedom (DOF) anthropomorphic robot powered entirely by pneumatic actuators. The control uses digital valves driven by pulse width modulation (PWM) to regulate air flow to the actuators. The robot is equipped with position sensors, which are used to provide feedback signals for local fuzzy controllers actuating the individual servoaxes. Trajectory tracking is guided by a module, which computes the robot's inverse kinematics, generating the references for the servoaxes. Experimental results illustrated in the article indicate that the controller is effective both in controlling single axes, and in tracking a trajectory. © 2002 Wiley Periodicals, Inc.

Experimental studies of the lower ionosphere using very low frequency radiowaves. (1976)

During the period 1967--1970 the phase and amplitude of twelve LF and VLF radiowave transmissions were monitored at Leicester for periods ranging from three years to a few weeks; the path lengths varied between 27km and 8,600km. The records taken were analyzed to extract the diurnal and seasonal behaviour of the signals. The horizontally polarized skywave of six local (U.K.) transmissions were isolated using loop aerials designed and built during the project, and the value of the ionospheric conversion coefficient R at noon and midnight throughout the year was obtained from the records. The apparent height of reflection was also measured. Full-wave calculations were performed to test several published models of the ionospheric D-region for consistency with the measurements. Modified models were also tested and new models for winter days, and for nights throughout the year were derived. TM mode propagation of VLF transmissions on eight long paths was examined, and TE mode propagation on three long paths was also examined at two receiving sites using orthogonal loop aerials to isolate the TE and TM modes. Measurements were found to be consistent with published predicted values of relevant ionospheric parameters. Disturbances resulting from solar flare activity were observed on all the paths and the anomalies present in the records were examined in detail. The contrasting response of the different paths was noted. Comparison of selected anomalies with the incident flux of X-radiation enabled an explanation for the different response of the various paths to be found. The effect of Polar Cap Disturbances and the influx of solar cosmic rays on transmission paths at different magnetic latitudes was also examined, and the anomalous response of a low latitude path during these geophysical disturbances was discovered.
Raman Lidar Profiling of Atmospheric Water Vapor (1994)

Detailed measurements of the distribution of water vapor in the atmosphere are needed for a variety of scientific inquiries, including global climate change and related issues in radiative processes (water vapor is the major greenhouse gas in the atmosphere), and studies of a variety of atmospheric processes such as cloud formation and atmospheric circulation. The Raman lidar is a leading candidate for an instrument capable of the detailed, time- and space-resolved measurements required by these and other studies.
DOOR syndrome (deafness, onycho‐osteodystrophy, and mental retardation): A new patient and delineation of neurologic variability among recessive cases (1993)

We report the seventeenth case of the recessive form of the DOOR syndrome. The parents were Guatemalan and not known to be consanguineous. The patient had developmental delay, severe sensorineural deafness, and abnormal nails and phalanges in the hands and feet. Urinary 2-oxoglutarate excretion was normal. The patient was among a subset of DOOR syndrome patients without seizures in infancy. This observation may be useful in discussing the prognosis for newly identified cases.
A sub-μW bio-potential front end in 65nm CMOS (2017)

A bio-potential amplifier intended for continuous monitoring of vitals characterized by its long operational lifetime is required to operate at the lowest power budget possible. Moreover, a compact active area directly related to portability is essential. This paper presents a 0.55pW auto gain controlled biopotential amplifier implemented in 65nm 1P7M CMOS for ECG signal classifier SoC. A chopper-stabilized amplifier is designed at 0.6V supply voltage to mitigate the DC offset and near DC flicker noise. The input ECG signal level is further set by the four gain levels of the variable gain amplifier (VGA) to provide maximum swing to the ADC. The whole system is integrated into a core are of 0.10mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> and can operate at a wide range of 0.6-1.2V supply voltage.
Tracking multiple moving objects with a mobile robot (2005)

One of the goals in the field of mobile robotics is the development of mobile platforms which operate in populated environments. For many tasks it is therefore highly desirable that a robot can determine the positions of the humans in its surrounding. We introduce sample-based joint probabilistic data association filters to track multiple moving objects with a mobile robot. Our technique uses the robot's sensors and a motion model of the objects being tracked. A Bayesian filtering technique is applied to adapt the tracking process to the number of objects in the sensor range of the robot. Our approach to tracking multiple moving objects has been implemented and tested on a real robot. We present experiments illustrating that our approach is able to robustly keep track of multiple persons even in situations in which people are temporarily occluded. The experiments furthermore show that the approach outperforms other techniques developed so far.
