Authors: Li Dazhou , Zhou Bo , Lin Chuan , Gao Jian , Gao Wei , Gao Aimin 
Published: November 2022

Background
During the COVID-19 pandemic, the accurate forecasting and profiling of the supply of fresh commodities in urban supermarket chains may help the city government make better economic decisions, support activities of daily living, and optimize transportation to support social governance. In urban supermarket chains, the large variety of fresh commodities and the short shelf life of fresh commodities lead to the poor performance of the traditional fresh commodity supply forecasting algorithm.

Methods
Unlike the classic method of forecasting a single type of fresh commodity, we proposed a third-order exponential regression algorithm incorporating the block Hankle tensor. First, a multi-way delay embedding transform was used to fuse multiple fresh commodities sales to a Hankle tensor, for aggregating the correlation and mutual information of the whole category of fresh commodities. Second, high-order orthogonal iterations were performed for tensor decomposition, which effectively extracted the high-dimensional features of multiple related fresh commodities sales time series. Finally, a tensor quantization third-order exponential regression algorithm was employed to simultaneously predict the sales of multiple correlated fresh produce items.

Results
The experiment result showed that the provided tensor quantization exponential regression method reduced the normalized root mean square error by 24% and the symmetric mean absolute percentage error by 22%, compared with the state-of-the-art approaches.

Aims: To evaluate the impact of the therapeutic foods on the hematological parameters of malnourished children below 5 years of age.
Study Design: This is a Prospective cross-sectional study.
Place and Duration of Study: Intensive Nutritional Recovery Center of Tessaoua, Maradi, Niger republic, from June 15 to September 10, 2022.
Methodology: We included 60 malnourished children (36 males, 24 females; age range 6-59 months) who are severely acutely malnourished. Standard survey forms that were developed for the purpose have permitted to obtain sociodemographic and hematological data (hemoglobin level and leukocyte count) concerning malnourished children.
Results: The results showed that among the 60 children that were surveyed, at entry, 50 (83.33%) were recorded to have a low hemoglobin level and 36 (60%) with highly elevated leucocyte count. At the end of treatment with therapeutic foods, it was observed an overall normalization of these parameters during an average duration of hospitalization.
Conclusion: Therapeutic foods have shown a significant positive influence on hematological parameters of malnourished children. Their use should therefore be encouraged in line with other strategies in order to ensure good and rapid recovery in malnourished children under five years of age.

Published: July 2002

AbstractObjective: To assess the association between previous term pregnancies and the prevalence of overweight in a group of urban women, controlling for the influence of age. Methods: One thousand twelve women, living in middle and low socioeconomic areas of Mexico City, were interviewed at home and their reproductive histories studied. Height and weight were measured in a clinical setting using controlled procedures. Overweight (BMI > 25) was the dependent variable used to calculate odds ratios and to perform a multiple logistic regression analysis. Results: Age and parity were significantly associated with the prevalence of overweight. Controlling for age, two or more previous pregnancies significantly increased the magnitude of the association. Conclusion: During the reproductive years parity seems to increase the risk of overweight in low and middle socioeconomic level urban women.
Early expression of the BM88 antigen during neuronal differentiation of P19 embryonal carcinoma cells
Authors: Boutou E. , Hurel C. , Matsas R. 
Published: July 2002

AbstractPrevious studies have shown that the BM88 antigen, a neuron‐specific molecule, promotes the differentiation of mouse neuroblastoma cells [23] (Mamalaki A., Boutou E., Hurel C., Patsavoudi E., Tzartos S. and Matsas R. (1995) The BM88 antigen, a novel neuron‐specific molecule, enhances the differentiation of mouse neuroblastoma cells. J. Biol. Chem. 270, 14201–14208). In particular, stably transfected with the BM88 cDNA, Neuro 2a cells over‐expressing the BM88 antigen are morphologically distinct from their non‐transfected counterparts; they exhibit enhanced process outgrowth and a slower rate of division. Moreover, they respond differentially to growth factors [10] (Gomez J., Boutou E., Hurel C., Mamalaki A., Kentroti S., Vernadakis A. and Matsas R. (1998) Overexpression of the neuron‐specific molecule BM88 in mouse neuroblastoma cells: Altered responsiveness to growth factors. J. Neurosci. Res. 51, 119–128). In order to further elucidate the role of the BM88 antigen in the differentiation of developing neurons we used the in vitro system of differentiating P19 cells which closely resembles early murine development in vivo. In this study, P19 cells were driven to the neuronal pathway with retinoic acid. We examined by immunofluorescence studies the expression of the BM88 antigen in these cells and we found that it correlates well with the expression of the polysialylated form of the neural cell adhesion molecule (PSA‐NCAM) which characterizes early differentiating post‐mitotic neurons. In contrast, very few of the BM88 antigen‐positive/PSA‐NCAM‐positive cells expressed neurofilament protein, a marker of more mature neurons. Our findings, in accordance with previously reported data, strongly suggest that the BM88 antigen is involved in the early stages of differentiation of neuronal cells.

Authors: Gibson Larry H. , Coughlin Robert W. 
Published: July 2002

AbstractOf five strains of Aureobasidium pullulans studied, NRRL Y‐2311–1 yielded the highest titer (26.2 g/L) of pullulan and formed the lowest amount of melanin‐like pigment. Sucrose was superior to glucose as the carbon and energy source on the basis of yield and titer of pullulan produced. Pullulan titer was higher (26.2 vs 5.1 g/L), biomass concentration was lower (6.9 vs 12.7 g/L), and DO was lower (0 vs 60% of saturation) when the fermenter was agitated by a marine propeller compared to Rushton impellers. Pullulan produced by strain NRRL Y‐2311–1 ranged in weight‐average molar mass ( Mw) from 486 KDa and number‐average molar mass ( Mn) from 220 Da on day 1 of growth to 390 KDa and 690 Da on day 6; Mw declined by about 35% from day 1 to day 3, the day of maximum pullulan titer. For the other strains, the ranges of molar mass on the day of maximum pullulan titer were 338–614 KDa ( Mw) and 100–6820 Da ( Mn).
Homologous Human Blood Protein Separation Using Immobilized Metal Affinity Chromatography: Protein C Separation from Prothrombin with Application to the Separation of Factor IX and Prothrombin
Authors: Wu Huiping , Bruley Duane F. 
Published: July 2002

AbstractProtein C (PC) is a natural anticoagulant and antithrombotic present in human blood at a concentration of 4 μg/mL. Its deficiency can result in excessive clotting and thrombosis. Protein C can be obtained from human blood plasma; however, there are other coagulant proteins in blood, including prothrombin (factor II), which is present in relatively large amounts and is one of the most active components. Protein C and prothrombin are homologous proteins with similar biochemical features; therefore, immunoaffinity chromatography is used for their separation. However, this technology is very expensive, protein C recovery and activity is low, and contamination problems with mouse antibody are likely. Immobilized metal affinity chromatography (IMAC) utilizes the protein metal‐binding properties for protein separation. Protein C has twelve surface‐accessible histidines, which are the major metal‐binding groups for IMAC separation. After investigating metal ion‐binding properties of protein C, we used an IDA‐Cu column to separate protein C and prothrombin. Following protein adsorption to the column, prothrombin was washed out using a sodium phosphate buffer containing 2 mM imidazole and protein C was recovered with 15 mM imidazole in the buffer. The mild elution condition allows a high protein C activity and a high recovery. Also, this technology introduces no immunoglobulins, and it is relatively inexpensive. IMAC could replace the immunoaffinity technology for the large‐scale separation of protein C from blood plasma Cohn Fraction IV‐1. In addition, this work demonstrates a significant application of this technology for the separation of factor IX from prothrombin. Prothrombin has proven to be a harmful contaminant in factor IX cocktails that have been administered to humans in the treatment of hemophilia B.

Published: July 2002

AbstractBackground:  Oral findings in acute leukemia (AL) are common and could be the presenting feature of the disease, namely, gingival enlargement, ulceration, bleeding, and infection. Gingival enlargement in AL is either due to leukemic infiltration, or due to reactive hyperplasia. To differentiate between them a biopsy is required, but being highly contraindicated, biopsy has been substituted in this study by fine needle aspiration cytology (FNAC).Method:  Gingival FNAC was performed on different sites in the upper and lower gingiva. Each site represents an interdental papilla, which was selected according to the clinical presentation, i.e., being enlarged or not. Seventy‐two adult AL patients received a cytological and clinical examination in this study, and the cases were classified and categorized according to the French‐American‐British (FAB) criteria.Results:  Twenty‐one cases were diagnosed as being infiltrated, 16 with gingival enlargement, 4 with no evidence of enlargement. In one case the infiltration affected the alveolar mucosa of an edentulous patient. In six cases the ginigva was enlarged without being infiltrated (reactive hyperplasia). Leukemic gingival enlargement was seen mostly in patients with acute myeloid leukemia, particularly M4 and M5 subtypes; however, two patients with acute mixed lineage leukemia (AMLL) were both affected with leukemic infiltration.Conclusion:  FNAC was shown to be a simple, non‐traumatic and useful diagnostic procedure for screening leukemic infiltration in gingival tissues in AL patients.

OBJECTIVEAlthough antithyroid drugs (ATD) are widely used in the treatment of Graves' disease, management protocols, especially treatment duration, remain a subject of debate. The rate of relapse after short‐term regimens of less than 6 months with ATD at decreasing doses is higher than after longer treatments from 12 to 24 months. As no prospective study has provided data on even longer protocols exceeding 2 years, we conducted a prospective trial to determine potential benefits of a 42‐month treatment compared with an 18‐month treatment.DESIGN, PATIENTS AND MEASUREMENTSThe aim of this prospective randomized trial was to compare relapse rates achieved two years after treatment withdrawal in patients who received carbimazole at decreasing doses for 18 months (n = 62) vs 42 months (n = 72). In addition to clinical relapse rate, the percentage of patients who normalized antithyroperoxidase (TPO) antibody and anti‐TSH receptor stimulating antibody (TSAb) levels and early iodine uptake at the end of treatment were assessed as outcome criteria.RESULTSThe relapse rate two years after discontinuation of treatment did not differ significantly in patients treated for 18 months from those treated for 42 months (36% vs 29%, NS). At the end of treatment, there was no significant difference between the two groups in the percentage of anti‐TPO positive patients (53% vs 46%, NS) or early iodine uptake (27% vs 21%, NS). Although the percentage of patients with TSAb was significantly lower in the 42‐month treatment group (18% vs 42%, P = 0.004) at treatment withdrawal, the percentage of TSAb‐positive patients did not significantly decrease between 18 and 42 months in this group (27% vs 18%, NS).CONCLUSIONTreatment duration greater than 18 months did not improve remission rate determined 2 years after treatment withdrawal or immunological variables or early iodine uptake measured at the time of discontinuation of treatment. These findings would indicate that, when a defined duration treatment is planned, prolonging treatment beyond 18 months does not provide any additional benefit.
Responses of tropical forest tree seedlings to irradiance and the derivation of a light response index
Authors: Agyeman V. K. , Swaine M. D. , Thompson J. 
Published: July 2002

Summary 1  Seedlings of 16 West African timber tree species were grown in six neutral shadehouses with irradiances 2%, 6%, 10%, 28%, 44% and 66% of unshaded values. 2  Tested species included well‐known pioneers, which showed negative growth in 2% irradiance but which responded strongly to increased irradiance, and very shade‐tolerant non‐pioneers, which had positive growth in 2% irradiance but responded only slightly to increased irradiance. 3  For all species, maximum growth occurred at an irradiance varying between 10% and 44%. The inhibition of growth at higher irradiance was greater in the more shade‐tolerant species. 4  Data from growth analyses were used in a principal components analysis to quantify the species’ positions on a light response gradient. The growth variables most strongly correlated with this gradient were relative growth rate (RGR) and relative diameter growth in 2% irradiance, and also apparent quantum efficiency and leaf mortality rate in both 2% and 66% irradiance. These results draw attention to the importance of performance in deep forest shade in defining differences among tropical forest tree species. 5  The second (independent) axis of the principal components analysis separated three species that are known from other experiments to be drought tolerant. Other species’ traits of functional significance (adult deciduousness, seed size, seed dispersal) were only weakly, if at all, associated with the gradient of light response. 6  Possible methods for efficient placement of other species on the gradient of light response are discussed. Formulation of standardized conditions simulating deep shade would allow diameter growth to be used as a simple non‐destructive measure of a species’ position on the gradient of light response, which could then be applied to any tropical forest flora.

Published: July 2002

Background: Hypotonic–hyporesponsive episodes (HHE) were once considered a contraindication to pertussis vaccination.Methodology: To evaluate the safety of further vaccination, chart review was conducted of 66 children who had experienced an HHE, and who were assessed in one of three special clinics in three capital city tertiary paediatric hospitals. Immediately prior to the HHE, 63 children had received whole‐cell pertussis vaccine, three had received acellular pertussis vaccine.Results: Sixty‐four of the 66 children were vaccinated in the special clinic, 59 with pertussis‐containing vaccines (55 acellular, four whole‐cell), without serious adverse events. There were no HHE after these further vaccinations.Conclusions: Previously healthy children who experience HHE reactions can safely continue standard vaccination schedules.
Effects of high-flux low-energy (20–100 eV) ion irradiation during deposition on the microstructure and preferred orientation of Ti0.5Al0.5N alloys grown by ultra-high-vacuum reactive magnetron sputtering

The effects of incident ion/metal flux ratio Ji/JMe and ion energy Ei on the microstructure, texture, and phase composition of polycrystalline metastable Ti0.5Al0.5N films produced by reactive magnetron sputtering have been investigated using x-ray diffraction (XRD), plan-view and cross-sectional transmission electron microscopy, and Rutherford backscattering spectroscopy. The films, typically ≂1 μm thick, were deposited at a pressure of 20 mTorr (2.67 Pa) in pure N2 on thermally oxidized Si(001) substrates at 250±25 °C. The N2+ ion flux to the substrate was controlled by means of a variable axial magnetic field superimposed on the permanent magnetic field of the magnetron. Films deposited at Ei=20 eV (≂10 eV per incident accelerated N) with Ji/JMe=1 exhibited a complete (111) texture with a porous columnar microstructure and an average column size of ≂30 nm. Increasing Ei from 20 to 85 eV, while maintaining Ji/JMe constant at 1, resulted in a small change in texture as the XRD intensity ratio I002/(I111+I002) increased from ≂0 to 0.14, a decrease in average column size to 25 nm, and a reduction in intracolumn porosity.
The stoichiometric ratio N/(Ti+Al) increased from 1 at Ei=20 eV with Ji/JMe=1 to 1.23 at Ei=85 eV indicating trapping of excess N while the lattice constant a0 increased from 0.4157 to 0.4188 nm due to compressive stress. Ei values ≥100 eV led to alloy phase separation. In contrast, maintaining Ei at ≂20 eV and increasing Ji/JMe from 1 to ≥5.2 resulted in a change from a porous (111) texture to a dense completely (002)-oriented microstructure with an increase in the average column size to 35 nm. N/(Ti+Al) and a0 remained essentially constant and the alloy remained single phase. Mechanistic pathways leading to microstructure and texture changes through variations in Ei at constant Ji/JMe and in Ji/JMe at constant Ei were found to be quite different. The average energy deposited per metal atom, 〈Ed〉=Ei(Ji/JMe), is therefore not a universal parameter, as has been previously proposed, for describing film growth.
Nominations, Ratings, and the Dimensions of Sociometric Status
Authors: Maassen Gerard H. , van der Linden Jos L. , Akkermans Wies 
Published: July 2002

In 1944, U. Bronfenbrenner remarked on the need for a two-dimensional model of sociometric status. The low value of the correlation between the variables liking and disliking-assumed basic dimensions of sociometric status-is often cited as evidence for the correctness of Bronfenbrenner’ssuggestion. Sociometric status is derived from a coalescence of judgements at the individual level. In this article we argue that score attribution at this level (where one group member assesses another) is one-dimensional along the liking-disliking continuum. Two-dimensionality of sociometric status arises at the group level. However, we also show that at this level liking and disliking are not two distinct dimensions, but the poles of just one, the other being visibility (or impact). If the one-dimensional model of liking score attribution on the individual level is accepted, the obvious thing to do is to instruct respondents accordingly. Rating scales are suitable for this. The rating-scale methods we suggested in previous publications (e.g. Maassen, Akkermans, &amp; van der Linden, 1996) are in keeping with this argument. Moreover, these methods may be recommended for their reliability, validity and for the variety of research designs to which they can be applied.
Ketone Bodies, Potential Therapeutic Uses

AbstractKetosis, meaning elevation of D‐ β‐hydroxybutyrate ( R ‐3‐hydroxybutyrate) and acetoacetate, has been central to starving man's survival by providing nonglucose substrate to his evolutionarily hypertrophied brain, sparing muscle from destruction for glucose synthesis. Surprisingly, D‐ β‐hydroxybutyrate (abbreviated “βOHB”) may also provide a more efficient source of energy for brain per unit oxygen, supported by the same phenomenon noted in the isolated working perfused rat heart and in sperm. It has also been shown to decrease cell death in two human neuronal cultures, one a model of Alzheimer's and the other of Parkinson's disease. These observations raise the possibility that a number of neurologic disorders, genetic and acquired, might benefit by ketosis. Other beneficial effects from βOHB include an increased energy of ATP hydrolysis ( ΔG') and its linked ionic gradients. This may be significant in drug‐resistant epilepsy and in injury and anoxic states. The ability of βOHB to oxidize co‐enzyme Q and reduce NADP + may also be important in decreasing free radical damage. Clinical maneuvers for increasing blood levels of βOHB to 2‐5 mmol may require synthetic esters or polymers of βOHB taken orally, probably 100 to 150 g or more daily. This necessitates advances in food‐science technology to provide at least enough orally acceptable synthetic material for animal and possibly subsequent clinical testing. The other major need is to bring the technology for the analysis of multiple metabolic “phenotypes” up to the level of sophistication of the instrumentation used, for example, in gene science or in structural biology. This technical strategy will be critical to the characterization of polygenic disorders by enhancing the knowledge gained from gene analysis and from the subsequent steps and modifications of the protein products themselves.
New practices for electronic publishing 1: Will the scientific paper keep its form?
Authors: Kircz Joost G. 
Published: July 2002

ABSTRACTDiscussion about the value of electronic documents is often hampered by starting from what is usual in the paper world and attempting to impose that on an electronic environment. In order to grasp the impact of the current electronic revolution, and formulate a policy for the future, we examine the aims and content of scientific communication. We then critically discuss the recommendations of an International Working Group [see Learned Publishing 2000:13(4) Oct. 251–8], and show the tension between these very reasonable recommendations and the reality of electronic publishing. We conclude that the scientific article will change considerably but that, in its new more composite form as an ensemble of various textual and non‐textual components, it will retain many of the current cultural and scientific requirements with regard to editorial, quality and integrity.
