Authors: El Yazeed Asmaa A. Abo , Harkan Ahmed I. , Ahmed Amira Y. , Elezz Ahmed A. Abo 
Published: January 2021

Introduction: Diagnosis of sepsis is important to reduce morbidity and mortality. Leptin is an important immunoregulatory hormone that enhances a number of immune responses in sepsis.
Objective: to assess serum leptin in diagnosing sepsis in critically ill pediatric patients.
Subjects and Methods: This study was carried out on 50 children divided into a case group included 40 critically ill patients initially sepsis free and fulfilling 2 of 4 criteria of SIRS admitted to the Pediatric Intensive Care Unit, children hospital, Tanta university and a control group included 10 apparently healthy children. According to the presence or absence of infection, our patients were classified into SIRS group and sepsis group. For all studied patients; serum leptin, CRP and others indicators of sepsis were measured at admission and 72h later, while were measured one time only for control group.
Results: patients who developed sepsis had significantly higher serum leptin levels than those of the control group and SIRS (33.9 ± 20.8 vs. 1.9 ± 0.4, 21.5+ 10.1 respectively, p>0.05).
Conclusion: Serum leptin may have a role in early diagnosis of sepsis.

Background: Many types of infection can cause pus Infections involving the bacteria; E.coli, so the assessment of multidrug Bacterial profile and patterns is needed to understand the source and management of these injuries.
Purpose: To determine infections and patterns toward antibiotics of pus isolates and recurrent wound infections in nongovernmental hospitals of Jordan
Methods: During period eleven months, 607 Patients were involved, out of which 128 patients had pus samples and/or recurrent wound infections. Data analysis was done using SPSS version 20. P value was set at <0.05.
Results: One hundred twenty eight (21.1%) out of 607 patients were identified to had pus isolates and/or wound recurrent infections 86(87%) out of 128 patients had infections with known pathogenic microbes. Microbiological culture pattern was total of 19 different pathogenic microorganisms were isolated from the participants, with mixed gram-positive and gram-negative species; percentage of 37% gram-positive aerobic bacteria and 63% gram-negative aerobic bacteria.
Conclusion: The global burden from multidrug resistant bacteria highly impacted in wound and pus-causing infections, either in hospital acquired infections or community acquired infections. The main causative agents of recurrent wound infection were Staph. aureus MRSA, E. coli, Pseudomonas aeruginosa, Acinetobacter spp (MDR). Gram-negative bacteria caused the most of infections by more than 67% comparing with gram-positive bacteria.
Cloacal Dysgenesis Sequence: Observations in Four Patients Including Three Fetuses of Second Trimester Gestation
Authors: Liang Xiayuan , Ioffe Olga B. , Sun Chen-Chih J. 
Published: July 2002

Cloacal dysgenesis is a rare malformation sequence. We studied cloacal dysgenesis in four fetuses, including three at 18–22 weeks of gestation. All four fetuses showed a smooth perineum with absence of anal, urethral, and/or vaginal openings. The urinary bladder was dilated in 3 cases. The labia majora and minora were absent in the two female fetuses; the scrotum and penis were absent in one male fetus and hypoplastic in the second. The kidneys were either absent (1 case), dysplastic (1 case), or hydronephrotic (1 case). Normal kidneys were seen in a fetus of 20–22 weeks gestation in whom the urinary obstruction was alleviated by a vesicocolonic fistula. This fetus did not have pulmonary hypoplasia. Severe renal anomaly and pulmonary hypoplasia are the limiting factors for the survival of infants born with cloacal dysgenesis. The unique observation of normal kidneys and lungs in one of our fetuses, despite anhydramnios, suggests that the effect of oligohydramnios on lung development may be limited early in gestation, at least up to 20–22 weeks. It may also indirectly support the theory that there are factors other than oligohydramnios that interfere with early lung development, such as reduced production of a pulmonary growth factor by the kidney or reduced proline production by malformed kidneys, that may cause decreased collagen formation and result in hypoplastic lung mesenchyme.
Evaluation of carton packing rules for high volume operations
Authors: Heady Ronald B. , Toma Alfred G. , Ristroph John H. 
Published: July 2002

AbstractWarehouse operations often include a step where large numbers of boxed products must be rapidly packed into shipping cartons, but little attention has been paid to the benefits that can be obtained by using a good packing rule. The work reported here is directed at determining the connection between packing rule and packing performance. First, the components of a packing rule are determined. Then, the components are combined into sixteen different packing rules and are analyzed to determine the resultant packing performances. The analysis is made using a computer program that simulates carton packing. Actual data from a company's operations are used as well as a set of synthetic data with known best‐case packing characteristics.The best packing rule is to pack the largest boxes first and align the longest‐middle‐shortest box dimensions with the longest‐middle‐shortest carton dimensions. This packing rule reduces the carton's average empty space by about one third when compared to disorganized procedures, and reduces the worst‐case results by about half. Despite these significant improvements, even the best rules could not reduce the average amount of empty space below about 20%.
The relationship between JIT manufacturing and performance in Mexican plants affiliated with U.S. companies
Authors: Lawrence John J. , Hottenstein Michael P. 
Published: July 2002

AbstractThis paper presents the results of a mail survey used to investigate the relationships between JIT manufacturing and performance in Mexico. Multi‐item scales were developed and used to measure key components of JIT. Four dimensions of performance were measured: productivity, quality, lead time, and customer service. Despite the existence of obstacles to its use in Mexico, JIT manufacturing was found to be significantly and positively correlated with performance. Plant size, industry, and the type of production process were all found to affect the relationship between JIT and performance. Results also indicated that the plant manager's citizenship may affect JIT implementation success. The paper concludes with recommendations for managers and researchers.
ATP synthase subunit c storage in the polymorphonucleocytes of late infantile and juvenile batten patients
Authors: Ansari Naseem H. , Cook Jay D. , Khanna Peeyush , Srivastava Satish K. 
Published: July 2002

AbstractIn late infantile and juvenile forms of neuronal ceroid lipofuscinosis, commonly known as Batten disease (BD), ATP synthase subunit c accumulates in the lysosomes of neural cells. By using polyclonal antibodies, raised against bovine liver subunit c and an image analysis system for the quantification of antibody‐linked alkaline phosphatase reaction, we have demonstrated that polymorphonucleocytes (PMN) from a late infantile and a juvenile BD patient stored several‐fold more subunit c as compared to normal PMN.

Published: July 2002

AbstractThe following series of experiments explores the post‐xenografting differentiation of a naturally occurring, non‐neuronal cell cultured from the leptomeninges of an 84‐year‐old woman. In culture, flat process‐bearing human cells from the leptomeninges were positive for GFAP and 200 kDa neurofilament protein (negative for 68, 160 kDa neurofilament protein). The C3 spinal cord was exposed in 30 adult athymic rats. The hindlimb dorsal columns were transected at C3 and the nerve fibers aspirated to form a pocket, into which 106 fast blue‐labeled, human leptomeningeal‐derived cells were placed. The C3 spinal cord was studied immunohistochemically over 60 days. Three days later the dorsal horn contained fast blue‐GFAP‐positive astrocyte‐like cells that were negative for neurofilament protein. By 7 days, large, process‐bearing, fast blue‐GFAP‐positive (neurofilament protein‐negative), astrocyte‐like cells joined the native astrocytes of the pia‐glia membrane and were in the gray matter of the spinal cord. Some of these astrocyte‐like cells were also positive for the human specific histocompatibility complex, HLADR. These data extend the age, species and tissue of origin for pluripotential cells for CNS transplantation.
Effects of nerve growtfactor on sympathetic neuron development in normal and limbless chick embryos
Authors: Saltis Johanna , Rush Robert A. 
Published: July 2002

AbstractWing bud removal in chick embryos has been shown to affect the generation of sympathetic neurons prior to the normal period of limb innervation [Saltis and Rush (1995) J. auton. nerv. Sys., 51, 117–127.]. Pyknotic activity occurred earlier within the peripherally deprived ganglion, suggesting that a precocious cell death of dividing sympathoblasts led to the reduced neuronal population. We have now sought to test whether the effect of limb bud extirpation can be overcome by the administration of nerve growth factor (NGF). Specifically, the peripherally deprived ganglion has been examined for mitotic activity and total neuronal numbers. In brachial ganglia from the operated side, neuron numbers decreased by 67% by embryonic day (E) 13, but by only 28% when NGF was administered from E9. Ganglia on the unoperated side were unaffected by the NGF treatment. In contrast, in embryos receiving NGF from E5 to E9, neuron numbers in the ganglia increased by more than 100%, on both the intact and operated side. This increase was accompanied by a greater proportion of 3H‐thymidine‐labelled neurons. We therefore conclude that NGF, in addition to its previously described role of preventing naturally occurring neuron death, can also affect the generation of sympathetic neurons. This ability of NGF to affect gangliogenesis is most likely achieved by increasing the survival of dividing neuroblasts, although a direct effect on mitosis has not been excluded.
Transvaginal sacrospinous colpopexy for marked uterovaginal and vault prolapse
Authors: Guner H , Noyan V , Tiras M.B , Yildiz A , Yildirim M 
Published: July 2002

AbstractObjective: The transvaginal sacrospinous ligament fixation technique was used as part of the vaginal repair procedure for marked uterovaginal prolapse, and in the treatment of vault prolapse. Method: Out of the 26 women treated with sacrospinous ligament suspension of the vaginal vault, 23 had marked uterovaginal prolapse and three had vault prolapse following hysterectomy. Patients with vault prolapse underwent posterior vaginal repair, obliteration of the enterocele sac and sacrospinous colpopexy. Patients with marked uterovaginal prolapse underwent vaginal hysterectomy with high ligation of the enterocele sac, anterior and posterior vaginal repair, and sacrospinous colpopexy. Bilateral salpingoopherectomy was added to the procedure in five patients. All patients were examined 6 weeks after the operation and, subsequently, on an annual basis. The mean follow‐up period was 2.6 years (1–5 years). Results: Out of the three patients with previous vault prolapse, none had recurrences. Out of the 23 patients with previous marked uterovaginal prolapse, only two had small cystocele, and one had small enterocele at 36 months following the operation. These patients were asymptomatic and did not need an operation. Vaginal vault prolapse was not observed in any of these patients. Two women had post‐operative urinary tract infection and five had buttock discomfort, which subsided after 2 months. No other intra‐ or post‐operative complications occurred. Conclusion: Transvaginal sacrospinous colpopexy can be performed together with vaginal hysterectomy, and anterior and posterior vaginal wall repair in patients with marked uterovaginal prolapse because of its high success in avoiding possible vault prolapse, and low intra‐ and post‐operative complication rates.

On the arithmetic sum of regular Cantor sets
Authors: Palis J. , Yoccoz J.C. 
Published: July 2002

We prove here that for any pair of regular Cantor sets in the line, either its arithmetic sum has Lebesgue measure zero or the pair can be approximated (through the image of a smooth diffeomorphism) by another one whose arithmetic sum contains an interval. The latter occurs when the Hausdorff dimension of the product of the sets is bigger than one.

Résumé
Nous démontrons que pour toute paire d’ensembles de Cantor réguliers sur la droite, ou bien leur somme arithmétique est de mesure de Lebesgue nulle, ou bien la paire peut être approchée (par l’image d’un difféomorphisme) par une autre dont la somme arithmétique contient un intervalle. Le dernier cas se produit quand la dimension de Hausdorff du produit des ensembles est plus grande que 1.

Nontrivial periodic solutions for strong resonance Hamiltonian systems
Authors: Chang K.C. , Liu J.Q. , Liu M.J. 
Published: July 2002

For a Hamiltonian system, in which the Hamiltonian is assumed to have an asymptotically linear gradient, the existence of nontrivial periodic solutions is proved under the assumption that the linearized operators have distinct Maslov indices at 0 and at infinity. Both the linearized operators may be degenerate. In particular, the results cover the “strong resonance” case.

Les opérateurs linéarisés peuvent même être dégénérés. En particulier, ces résultats comprennent le cas de « résonance forte å.
Young measure solutions for nonlinear evolutionary systems of mixed type
Authors: Demoulini Sophia 
Published: July 2002

This is a study of measure-valued solutions for systems of mixed type modelled by a hyperbolic-elliptic and a dispersive-parabolic system in arbitrary dimension. Existence is established by time-discretisation of the equations which is solved by the minimisation of a non-convex functional. By relaxation, a Young measure solution is obtained for every time step. Uniform bounds derived by energy considerations allow passage to the limit of continuous time. The potential gradient and the identity are shown to be independent with respect to the Young measure.

Résumé
Ceci est une étude des mesures, solutions des systèmes de type mixte, modélisés par un système hyperbolique-elliptique et un système dispersif-parabolique, en dimension quelconque. Un résultat d’existence est établi par une discrétisation en la variable temps d’une équation qui est équivalente à la minimisation d’une fonctionnelle non convexe. Par relaxation, une solution, mesure de Young, est obtenue à chaque étape. Des bornes uniformes dérivant de la fonction énergie permettent de passer à la limite en temps continu. Nous prouvons que le gradient du potentiel et l’identité sont indépendants par rapport à la mesure de Young.

On nonlinear stability of polytropic galaxies
Authors: Wolansky G. 
Published: July 2002

We consider a certain class of stationary solutions of the Vlasov–Poisson system with a Newtonian potential. These solutions represent some spherically-symmetric, rotating galaxies obeying the generalized Emden–Fowler law. A nonlinear stability under spherically symmetric perturbations is proved. The proof is based on an adaptation of the energy-Casimir method, which implies a uniform estimate on the mass distribution of the perturbed solutions.

Résumé
Nous considérons une certaine classe de solutions stationnaires du système de Vlasov–Poisson avec un potentiel Newtonien. Ces solutions décrivent des galaxies tournantes, à symétrie sphérique, obéissant à la loi d’Emden–Fowler. La stabilité nonlinéaire aux perturbations sphériquement symétriques est démontrée. La preuve repose sur une adaptation de la méthode d’énergie-Casimir, laquelle implique une estimation uniforme sur la distribution de masse des solutions perturbées.
