Authors: Sikoki F. D. , Onojake M. C. , Omokheyeke O. , Onyagbodor P. O. 
Published: May 2021

Sediment and biota samples were collected biannually from the Bonny/New Calabar River Estuary in Niger Delta, Nigeria and analysed for poisonous metals of interest to the International Atomic Energy Agency (Pb, Cd, and Hg) using atomic absorption spectrophotometer A-500 and Direct Mercury analyser (DMA-80). Results for biota showed that Cd ranged from 0.003 to 0.558 ± 0.01mg/kg, Hg ranged from 0.014 ± 0.004 to 0.021± 0.010 mg/kg, Sediment: Cd ranged from 0.022 ± 0.001 – 0.82 ± 0.0002 mg/kg; Hg 0.010 ± 0.005 to 0.027 ± 0.009 mg/kg. Lead was below the detection limit of the instrument both in biota and sediment. The concentrations of the respective poisonous metals were within the permissible limit of the World health organization. The study showed high concentration of Cd in Crayfish compared to other seafood. The bioaccumulation factor showed higher level of Hg compared Cd while the Analysis of variance for the three stations did not show any significant variation among the three stations. Regular monitoring and comparison of level of contamination with regulatory bodies are advocated to prevent the concentration of the metal contaminants from getting to an alarming level.

Introduction: Technological devices have become a very important part of our everyday life. These electronic devices create an artificial electromagnetic field (EMF) and emit radiofrequency radiations (RFR) which have been reported to have deleterious effects on various tissues in living organisms. Fish oil is a rich source of the n-3 (also known as omega-3) fatty acids, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). The cerebellum plays an important role in motor control and the coordination, precision and timing of movements, as well as in motor learning. This study investigated the effect of radiofrequency radiation on the structures of the cerebellum of adolescent Wistar rats, its effect on pre-pubertal development and the potential attenuative properties of fish oil omega-3 fat.
Materials and Methods: Forty (n=40) adolescent Wistar rats of approximately 35 days old were divided into five groups labelled A-E. A 4G RFR-emitting WI-FI device served as the RFR source. The 4G radiofrequency transmitter was installed at a distance of 0.5 meters from the base of the cage housing the experimental animals in each group. The fish oil was administered orally to the animals. Rats were sacrificed after 28 days of treatment and their brains harvested. The cerebellar tissues were excised and processed for histological, immunohistochemical and biochemical observations. Neurobehavioural studies including Barnes Maze and beam walk were carried out before sacrifice.
Results: 4G radiofrequency radiation caused distortions in the morphology and spatial arrangement of Purkinje cells in the cerebellar tissues. It also induced neuroinflammation as marked by enhanced astrocyte reactions. Also, behavioural aberrations including negative changes in key memory parameters such as increased latency and error poke in Barnes maze assays, and increased movement parameter errors were attributable to FRR effects. Also, aberrations in neurotransmitters activities levels and vital neurochemistry enzymes were observed. The administered Omega-3 fat had an attenuative effect on the affected cortical structures, neurochemistry and selected neurobehavioural parameters.

Published: May 2021

Aims: The purpose of the study is to evaluate the frequency, distribution and determinants of tongue lesions in our teaching institute. Also to find an association of common tongue lesions with various study variables.
Study Design: Cross-sectional study design.
Place and Duration of Study: The study was conducted at Fatima Jinnah Dental College & Hospital, Karachi, Pakistan. All the lesions presented on the tongue were included reported from January 2017 to December 2020.
Methodology: There were 670 oral lesions documented in the Department of Oral Pathology and Oral Medicine out of which 93 (13.8%) represented tongue lesions. We included 93 patients with tongue lesions (45 men, 48 women; age range 18-80 years). These lesions include the atrophic tongue, geographic tongue, candidiasis, keratotic lesion, ulceration, oral pigmentation, fibroma, black hairy tongue, traumatic neuroma, herpes infection, oral submucous fibrosis, and oral squamous cell carcinoma.
Results: In the study, common clinical presentations on the tongue were ulceration (29%), erythematous/depapillated tongue (22.6%), white keratotic and plaque-like lesions (21.6%), and black discoloration (8.6%). The clinical presentation was statistically associated with gender (p=0.03), age (p=0.04) and site of lesion (p<.001). Atrophic glossitis (19.4%), traumatic ulcer (12.9%), pseudomembranous candidiasis (12.9%), oral pigmentation (8.6%), oral squamous cell carcinoma (7.5%), geographic tongue (6.5%), recurrent aphthous stomatitis (6.5%), and frictional keratosis (6.5%) were most commonly reported tongue lesions. There was a relationship of tongue lesions with causes and site of the lesion (P<0.001).
Conclusion: Initial tongue lesions may reflect underlying massive abnormal changes and this could be an early diagnostic parameter. Through vigilant screening of the oral mucosa, we may be able to detect such mucosal alterations and search out the possible cause in order to provide effective treatment to the patient. In this way, we may also prevent the malignant transformation of any susceptible oral lesions.

Perinatal outcome of idiopathic small for gestational age pregnancies at term: the effect of antenatal diagnosis
Authors: Ohel G. , Ruach M. 
Published: July 2002

AbstractObjective: To evaluate the effect of antenatal detection of the idiopathic term small for gestational age (SGA) fetus upon perinatal outcome. Methods: A 3‐year retrospective review of all term pregnancies with no associated maternal disease, with birth weights at least 2 S.D.s below the mean for gestational age. Perinatal outcome measures were compared between pregnancies that were diagnosed as SGA antenatally, and those that were detected only after delivery. Results: Of 158 term SGA pregnancies, 47 were diagnosed antenatally, and 111 were recognized as such only after delivery. The antenatally diagnosed group had a higher incidence of adverse neonatal outcome (P < 0.01), as well as higher incidences of inductions of labor and emergency Cesarean sections (68% vs. 12%, P < 0.001, and 23% vs. 10%, p < 0.03, respectively). Logistic regression analysis with adverse neonatal outcome as the dependent variable has shown it to be dependent only on gestational age at delivery (P < 0.004), and birth weight (P < 0.001), and not on antenatal diagnosis. Conclusions: Antenatal detection of SGA may be associated with an increased incidence of obstetric interventions, with no demonstrable positive effect upon the short‐term neonatal outcome.

Published: July 2002

AbstractObjective: To estimate the timing of brain damage involved in the onset of periventricular leukomalacia in the perinatal period we recorded and analyzed neonatal electroencephalograms (EEGs). Methods: Twenty‐four preterm birth infants proved by real time ultrasonic examination or MRI to be suffering from periventricular leukomalacia underwent serial electroencephalography from soon after birth. Results: Thirteen (54%) demonstrated intrauterine injury patterns, 2 infants (8%) showed postnatal injury, and in the remaining 9 cases (38%) the time of injury could not be determined by electroencephalography. Antepartum maternal hemorrhage (6), premature rupture of membranes (3), twining (3), chorioamnionitis (2), and perinatal asphyxia (2) were complications encountered in the group with intrauterine injury patterns. Conclusions: Our observations suggest that more than half of periventricular leukomalacia cases are associated with premature birth infants showing intrauterine injury patterns on electroencephalography, indicating the existence of intrauterine insult.
The antecedents of buying firms' efforts to improve suppliers
Authors: Krause Daniel R 
Published: July 2002

AbstractThis study examined the factors that precede buying firms' time and resource investments in supplier development. Supplier development is any effort by a buying firm with a supplier to improve the supplier's performance and/or capabilities and to meet the buying firm's short and/or long term supply needs. The purposes of the study were to identify important factors that influence a firm's involvement in supplier development, develop reliable and valid measures of these factors, and test hypotheses regarding how the factors interrelate. We tested the hypotheses that the buying firm's environment and top management's recognition of purchasing's importance, influence the buying firm to adopt a strategic perspective toward supplier performance. We further hypothesized that the firm's strategic perspective toward supplier performance influences supplier commitment to the buying firm. The primary dependent factor is the buying firm's involvement in supplier development activities. The antecedents to this factor include supplier commitment, expectation of relationship continuity and effective buyer–supplier communication. Multiple‐item scales were used to measure the factors. A structural model that postulates the relationships among these factors was tested using data gathered from a cross‐industry sample of high‐level U.S. purchasing executives.
DL‐penicillamine induced alteration of elastic fibers of periosteum‐perichondrium and associated growth inhibition: an experimental study
Authors: Gigante A. , Chillemi C. , Quaglino D. , Miselli M. , Pasquali‐Ronchetti I. 
Published: July 2002

AbstractPerichondrium‐periosteum, being of collagen and elastic fiber, is regarded as a bone growth regulating factor. The aim of the present study was to investigate the role of collagen and elastic fibers on bone growth, by interfering with the fiber assembly in growing chicks upon administration of DL‐penicillamine (DL‐PNA).Our findings demonstrated that DL‐PNA determined relevant modifications in the perichondrium‐periosteum, as shown by histochemical, histomorphometrical, biochemical and ultrastructural analysis. This chemical has been shown to inhibit the formation of desmosine cross‐links in elastin and to induce an increase of elastin associated microfibrils. On the contrary, the collagen network and the biochemical collagen markers were not affected. These changes resulted in a dramatically reduced growth of long bones in comparison with control. Perichondrial‐periosteal regulation of bone growth may be mediated by mechanical and biological factors. This study demonstrates a microstructural change in the perichondrium‐periosteum with decreased elastin and increased elastic microfibrils content in penicillamine treated chicks. The mechanism linking changes in the perichondrium‐periosteum with altered growth still needs to be elucidated. © 2001 Orthopaedic Research Society. Published by Elsevier Science Ltd.

Cell specific‐chondroitin sulfate proteoglycan expression during CNS morphogenesis in the chick embryo
Authors: Domowicz Miriam , Mangoura Dimitra , Schwartz Nancy B. 
Published: July 2002

AbstractThere is increasing evidence that proteoglycans, particularly chondroitin sulfate proteoglycans (CSPGs), are integral components in the assembly of the extracellular matrix during early stages of histogenesis. The differential expression of several CSPGs in the developing CNS has raised questions on their origin, phenotype (chemical and structural characteristics), regulation of expression and function. The S103L monoclonal antibody has been an invaluable specific reagent to identify and study a large and abundant CSPG in embryonic chick brain. In the present study we demonstrate that during embryogenesis of the chick CNS, the S103L CSPG (B‐aggrecan) is synthesized by neurons of all major neuronal cell types but not by astrocytes, is developmentally regulated, and is associated predominantly with neuronal somata, suggesting that neuronal‐specific regulatory mechanisms control the expression of the S103L CSPG in culture. Neurons also exhibit differential expression of glycosaminoglycan type (i.e., KS) and sulfation patterns on different CSPGs when compared to astrocytes, meningial cells or chondrocytes, implying the existence of additional, cell type‐specific modes of regulation of the final CSPG phenotype (chemical and structural posttranslational characteristics). A specific temporal pattern of expression of the S103L‐CSPG was observed which may contribute to conditions that induce or stabilize specific cell phenotypes during CNS development. In contrast, the other major CSPG in the CNS recognized by the HNK‐1 antibody, is synthesized by all cell types of different cell lineages over the entire embryonic period, suggesting a more global cell maintenance function for this CSPG.
Association of the HNK‐1 epitope with the detergent‐soluble G4 isoform of acetylcholinesterase from human neuroblastoma cells
Authors: Johnson Glynis , Moore Samuel W. 
Published: July 2002

AbstractThe HNK‐1 carbohydrate epitope is expressed in neural and natural killer cells and is a mediator of cell adhesion. It is well documented that acetylcholinesterase has a secondary function in cell adhesion and differentiation. The presence of HNK‐1 on isoforms of Torpedo and Electrophorus acetylcholinesterase, as well as isoforms from the bovine central nervous system has been described. In this paper, we have investigated the association of the epitope with acetylcholinesterase from human neuroblastoma cells. Acetylcholinesterase was extracted, with or without detergent, purified on immunoaffinity columns and the isoforms separated by sucrose density gradient sedimentation. Secreted acetylcholinesterase, from spent serum‐free culture medium, was similarly treated. The presence of the HNK‐1 epitope was determined by ELISA using the anti‐HNK‐1 and Elec 39 monoclonal antibodies. The epitope was found to be associated with the detergent‐soluble G4 isoform, but not with the hydrophilic G1 nor the secreted hydrophilic G4 isoforms. Likewise, no HNK‐1 was observed associated with human erythrocyte acetylcholinesterase. These results indicate that acetylcholinesterase‐G4, anchored in the extracellular membrane, is capable of mediating cell–substrate adhesion through HNK‐1.
