Hematological Status of Female Basketball Players (1993)

Abstract: The transport of oxygen has been shown to be impaired in certain female athletic populations. The purpose of the present investigation was to (a) compare the hemoglobin, hematocrit, and serum ferritin concentrations between female basketball players (BB) and female nonathletes (CON); and (b) examine the variation in hemoglobin, hematocrit, serum ferritin, and maximal oxygen consumption across a competitive season in female basketball players. Fifteen Division I female basketball players and 22 age-matched female controls served as subjects. Preseason (PRE) blood samples were taken and analyzed for serum ferritin (FERR), hemoglobin (HGB), and hematocrit (HCT). In addition, maximal oxygen consumption (MXOX) and percent body fat (FAT) were measured. All measures were repeated at midseason (MID) and postseason (POST). The basketball players were heavier (Xweight = 73.2 vs. 58.9 kg), taller (Xweight = 178.22 vs. 164.55 cm), less fat (19.4 vs. 23.2%; p < 0.05), more muscular (58.7 vs. 45.1 kg; p < 0.05), and in better aerobic condition (43.9 vs. 39.4 ml.kg–1.min–1; p < 0.05). Significant correlations were found among the hematological variables but no hematological variable correlated with MXOX. Thirteen percent of the BB group had low FERR at PRE. Across time, only FERR decreased significantly and only for the BB group. The results of this study suggest that serum ferritin levels appear to be declining in this population although not all athletes reached significantly low levels.
A method of position and attitude measurement of vehicle using fan shaped laser beam and corner cube (1993)

A method is proposed to measure the position and attitude of a vehicle on the road by use of laser transceivers on the vehicle and retro-reflecting targets on a side of the course. The laser transceivers emit fan shaped laser beams and detect the returned laser beams reflected by the retro-reflecting targets. The time data when the laser beams return to the transmitter vary, depending on the movement of the vehicle. An onboard computer calculates the position and attitude from the time data. The measurement principle and the simulation results are reported.
Determination of the phenol index of water by stepwise injection analysis with offline preconcentration by extraction chromatography (2012)

A procedure for the photometry determination of the phenol index of aqueous media is developed, which involves the preliminary separation of alkylphenols and their derivatives from water samples in sampling. Samples are filtered through an extraction chromatography column containing tributyl phosphate as an active component of the stationary phase followed by their quantification under the conditions of stepwise injection analysis. The detection limit of the method is 0.1 μg/L for simple phenol.
SYNTHESIS OF WATER-SOLUBLE URETHANE ACRYLATE CATIONOMERS AND THEIR ULTRAVIOLET COATING PROPERTIES (1999)

Water-soluble urethane acrylate cationomers were synthesized by incorporating N-methyldiethanolamine (MDEA) into the molecular backbone for an application of ultraviolet (UV) curing. It was found that they were easily dissolved in, because of the sufficient hydration ability of the incorporated cationic groups. Differing from conventional urethane acrylate derivatives, when UV-cured, the films of the urethane acrylate cationomers showed significantly improved coating properties. This was because of the formation of the ionic hard domains in the urethane acrylate network. In dynamic mechanical analysis (DMA), the formation of the ionic hard domain could be confirmed by detecting the glass transition peak Tgh, around 23.4°C. The dyeing of the urethane acrylate cationomer films was considerably favorable because of their positively-charged network structure.

CONTINUOUS DETERMINATION OF THE AVERAGE SOUND VELOCITY OVER AN ARBITRARY PATH (1966)

A reasonably accurate determination of the velocity of sound in the open air along a path of arbitrary length by some inexpensive means is the crux of sonic atmospheric sensing. At present, this is accomplished by measuring either time delays or phase differences of an acoustic signal. This paper explores the technique of phase measurement and proposes a direct approach to the problem of determining the sound speed within an arbitrary layer. By means of the phase technique, the initial conditions of the sound velocity and the vector wind may be determined. The temporal distribution of the sound speed is found from an equation for the average sound velocity along the paths between the sound source and two opposing transducers.
Least squares linear lags and limited memory filters (1987)

Pure autoregressive (AR) models which are linear in the short term, that is when a variable can be predicted by linear regression on a limited number of past observations, are discussed. When evenly spaced observations are available, a fixed set of AR coefficients can be calculated independent of the data. For filtering purposes, such a lag structure can be implemented recursively with an efficient algorithm. The method of computing variance recursively is also derived. A complete algorithm is presented in the appendix.
Hydroxyapatite bioactivated bacterial cellulose promotes osteoblast growth and the formation of bone nodules (2012)

The goal of this study was to investigate the feasibility of bacterial cellulose (BC) scaffold to support osteoblast growth and bone formation. BC was produced by culturing Acetobacter xylinum supplemented with hydroxyapatite (HA) to form BC membranes (without HA) and BC/HA membranes. Membranes were subjected to X-ray photoelectron spectroscopy (XPS) analysis to determine surface element composition. The membranes were further used to evaluate osteoblast growth, alkaline phosphatase activity and bone nodule formation. BC was free of calcium and phosphate. However, XPS analysis revealed the presence of both calcium (10%) and phosphate (10%) at the surface of the BC/HA membrane. Osteoblast culture showed that BC alone was non-toxic and could sustain osteoblast adhesion. Furthermore, osteoblast adhesion and growth were significantly (p ≤0.05) increased on BC/HA membranes as compared to BC alone. Both BC and BC/HA membranes improved osteoconductivity, as confirmed by the level of alkaline phosphatase (ALP) activity that increased from 2.5 mM with BC alone to 5.3 mM with BC/HA. BC/HA membranes also showed greater nodule formation and mineralization than the BC membrane alone. This was confirmed by Alizarin red staining (ARS) and energy dispersive X-ray spectroscopy (EDX). This work demonstrates that both BC and BC/HA may be useful in bone tissue engineering.
Design of double intelligent parking garage based on HuiYu technology (2019)

Abstract In view of the ubiquitous parking problem in the city, a double-layer intelligent parking garage that saves space, is smart and labor-saving. On the basis of the existing parking garage, the first problem to be solved is how to effectively use the transitional parking space in the three-dimensional garage (mainly refers to the parking space that the vehicle cannot be occupied by the upper vehicle after parking). In order to solve the above problems, this paper designed a double-deck parking garage to solve this problem. Mainly by the left and right lateral movement and vertical movement of the lower parking space. All parking spaces are free to move up and down to ensure that the lower parking space can be fully loaded without affecting the upper parking vehicle. Based on Huiyu’s innovative technology, a double-layer intelligent parking garage was designed. The Huiyu model is used to complete the mechanical system design and production of physical models. The man-machine operation panel is compiled with ROBO PRO software. With button-type access, it has the function of non-slip and stable operation. At the same time, the optimal path algorithm saves time. The double-decker smart parking garage is safe, small, efficient and intelligent. It can park and pick up the car with a key. The double-deck parking garage achieves maximum use of space and is both reliable and economical. The double-deck intelligent parking garage is designed to meet the desired sporting requirements, removing the upper vehicle while ensuring that the vehicle’s bottom layer does not move. At the same time, the optimal path algorithm makes it a powerful guarantee for fast access to vehicles. The double-layer intelligent parking garage designed and built has met the design requirements. Further improvement is to transform from Huiyu model to actual product, and it is necessary to solve the problem of parking garage bearing.

[Kinetin and the germinating capacity of Lupinus multilupa seeds]. (1987)

The effect of kinetin (10(-6) M and 10(-4) M) on the germinating capacity and incorporation of 8-C14 adenine into DNA, RNA and RNA Poly A+ of embryos and cotyledons from Lupinus multilupa L. seeds have been studied. Kinetin enhanced the germinative capacity of the seeds and the incorporation of 8-C14 adenine into DNA, RNA and Poly A+ of embryos and cotyledons. However, there seems to be no close relationship between the DNA and RNA biosynthesis of embryos and cotyledons and the ability of the seeds to germinate and their embryos to continue growing.
Acute cyanide poisoning complicated by lactic acidosis and pulmonary edema (1977)

Massive cyanide poisoning occurred in a 21-year-old man who had ingested 600 mg of potassium cyanide. The clinical course was marked by acute pulmonary edema and lactic acidosis. Because the poison was unidentified until nine hours after ingestion, the patient received only supportive treatment which included diuresis, oxygen, bicarbonate, and assisted ventilation. A review of the literature shows that many case reports are poorly documented and do not provide a firm basis for evaluating therapy. To our knowledge, only four patients, including ours, have had blood levels of cyanide measured. In the absence of a suitable history, diagnosis of cyanide poisoning is difficult. A simple chemical test which can be performed on gastric aspirate is available. Hydroxocobalamin may be used as a nontoxic specific antidote. Nonspecific supportive therapy is of great importance.
α-Latrotoxin Receptor, Latrophilin, Is a Novel Member of the Secretin Family of G Protein-coupled Receptors (1997)

alpha-Latrotoxin (LTX) stimulates massive exocytosis of synaptic vesicles and may help to elucidate the mechanism of regulation of neurosecretion. We have recently isolated latrophilin, the synaptic Ca2+-independent LTX receptor. Now we demonstrate that latrophilin is a novel member of the secretin family of G protein-coupled receptors that are involved in secretion. Northern blot analysis shows that latrophilin message is present only in neuronal tissue. Upon expression in COS cells, the cloned protein is indistinguishable from brain latrophilin and binds LTX with high affinity. Latrophilin physically interacts with a Galphao subunit of heterotrimeric G proteins, because the two proteins co-purify in a two-step affinity chromatography. Interestingly, extracellular domain of latrophilin is homologous to olfactomedin, a soluble neuronal protein thought to participate in odorant binding. Our findings suggest that latrophilin may bind unidentified endogenous ligands and transduce signals into nerve terminals, thus implicating G proteins in the control of synaptic vesicle exocytosis.
Mycoplasmas and cancer (2014)

The standard of care for patients suffering cancer often includes treatment with nucleoside analogues (NAs). NAs are internalized by cell-specific nucleobase/nucleoside transporters and, after enzymatic activation (often one or more phosphorylation steps), interfere with cellular nucleo(s)(t)ide metabolism and DNA/RNA synthesis. Therefore, their efficacy is highly dependent on the expression and activity of nucleo(s)(t)ide-metabolizing enzymes, and alterations thereof (e.g. by down/upregulated expression or mutations) may change the susceptibility to NA-based therapy and/or confer drug resistance. Apart from host cell factors, several other variables including microbial presence may determine the metabolome (i.e. metabolite concentrations) of human tissues. Studying the diversity of microorganisms that are associated with the human body has already provided new insights in several diseas es (e.g. diabetes and inflammatory bowel disease) and the metabolic exchange between tissues and their specific microbiota was found to affect the bioavailability and toxicity of certain anticancer drugs, including NAs. Several studies report a preferential colonization of tumor tissues with some mycoplasma species (mostly Mycoplasma hyorhinis). These prokaryotes are also a common source of cell culture contamination and alter the cytostatic activity of some NAs in vitro due to the expression of nucleoside-catabolizing enzymes. Mycoplasma infection may therefore bias experimental work with NAs, and their presence in the tumor microenvironment could be of significance when optimizing nucleoside-based cancer treatment.

Regression of Refractory Rhabdomyosarcoma After Allogeneic Stem-Cell Transplantation (2003)

A 17-year-old girl developed refractory rhabdomyosarcoma. An allogeneic peripheral-blood stem-cell transplant was performed after a myeloablative regimen. Although rapid disease progression had resolved transiently, after the start of high-dose chemotherapy, re-progression was apparently observed from day 14. However, delayed tumor regression occurred on day 30, shortly after the reduction of immunosuppressants. She achieved a partial remission. The second tumor regression provides suggestive clinical evidence that graft-versus-tumor effect may occur against rhabdomyosarcoma. Although further investigation is required, allogeneic stem-cell transplantation could provide a new therapeutic option for refractory rhabdomyosarcoma.
Approach to thermal equilibrium in harmonic crystals with polyatomic lattice (2018)

We study transient thermal processes in infinite harmonic crystals with complex (polyatomic) lattice. Initially particles have zero displacements and random velocities such that distribution of temperature is spatially uniform. Initial kinetic and potential energies are different and therefore the system is far from thermal equilibrium. Time evolution of kinetic temperatures, corresponding to different degrees of freedom of the unit cell, is investigated. It is shown that the temperatures oscillate in time and tend to generally different equilibrium values. The oscillations are caused by two physical processes: equilibration of kinetic and potential energies and redistribution of temperature among degrees of freedom of the unit cell. An exact formula describing these oscillations is obtained. At large times, a crystal approaches thermal equilibrium, i.e. a state in which the temperatures are constant in time. A relation between equilibrium values of the temperatures and initial conditions is derived. This relation is refereed to as the non-equipartition theorem. For illustration, transient thermal processes in a diatomic chain and graphene lattice are considered. Analytical results are supported by numerical solution of lattice dynamics equations. ${\bf Keywords}$: thermal equilibrium; stationary state; approach to equilibrium; polyatomic lattice; complex lattice; kinetic temperature; harmonic crystal; transient processes; equipartition theorem; temperature matrix.
Protocol for Quantitative Detection of Elemental Sulfur and Polysulfide Zero‐Valent Sulfur Distribution in Natural Aquatic Samples (2009)

A HPLC‐based protocol has been developed for the determination of zero‐valent sulfur (ZVS) speciation, including solid, colloidal elemental sulfur and individual inorganic polysulfides in natural aquatic samples. The protocol includes four experimental procedures: (1) determination of polysulfide speciation by rapid single‐phase derivatisation with methyl trifluoromethanesulfonate; (2) determination of the sum of polysulfide and colloidal sulfur by reaction with hydrogen cyanide (cyanolysis); (3) determination of total zero‐valent sulfur by treatment with zinc chloride followed by extraction with chloroform; and (4) chromatographic determination of polythionates without sample pre‐treatment. With proper sampling and preservation techniques in the field or on board ship, this combination of methods allowed the quantitative determination of: (a) individual polysulfide species; (b) dispersed colloidal sulfur; (c) dispersed solid elemental sulfur; and (d) tetra‐, penta‐ and hexathionates. With minor modification, the method could be expanded to include other polythionates. Sixteen various wet chemical and liquid chromatographic methods were tested on nine synthetic reference samples (including solid elemental sulfur, colloidal elemental sulfur, inorganic polysulfides and polythionates) to establish the optimal protocol. The protocol was further evaluated by analysing the zero‐valent sulfur content in microbially‐produced sulfur and in sulfur from two natural samples of sulfide‐rich seawater from tidal flats pools of the Wadden Sea (Germany).
