Adverse Health Effects of Low Dose of Ionizing Radiation among Health Care Workers

Introduction: Ionizing radiation (IR) is an occupational hazard that can induce many biological effects on exposed health care workers (HCWs). However, the health risks of low dose (below 100mSv) are controversial due to a lack of direct evidence on human. Aim of work: To identify the adverse health effects of exposure to low dose of ionizing radiation on general health status of health care workers at Ain Shams University hospitals. Materials and methods: A comparative cross-sectional study was conducted including 50 HCWs from different departments of Ain Shams University hospitals: exposed group (exposed to IR for at least I year) (No=25) and matched unexposed control group (No =25). Both groups were interviewed using a structured questionnaire. Complete blood count was done for both groups. Recording readings of personal exposure to IR by badge film dosimeter was done after approval from workplace authority. Results: Regarding general health status and wellbeing of workers, most of exposed group had perception of average health status, while most of unexposed group had perception of good health status. Significantly higher sickness absenteeism during the last 6 months was found among the exposed group. A significant adverse health effects, were recorded among exposed compared to control group as hair fall, musculoskeletal pain, pain in upper abdomen, constipation, decreased visual acuity, in addition to be easily agitated. During the last 30 days exposed group had significantly higher frequencies of GIT disturbances and common cold or infections in comparison to unexposed group. Results showed that the Mean Corpuscular Hemoglobin (MCH), absolute lymphocyte and monocyte counts were significantly lower while relative basophils % was significantly higher among exposed in comparison to unexposed group (although all parameters were within normal range in both groups). Conclusion and recommendations: Chronic exposure to IR -even in small dose- may lead to significant health complains (adverse health effects) and may affect general health status among exposed group compared to the control one. Personal monitoring for ionizing radiation, periodic medical examination, and increasing level of protection for exposed workers are of utmost importance.
Phenotypic diversity of Xanthomonas oryzae pv. oryzae in Nepal

Fifty-three strains of Xanthomonas oryzae pv. oryzae collectet from various rice-growing areas in Nepal were characterized for differences in biochemical and physiological characteristics, bacteriocin production, and virulence. Numerical analysis of phenotypic features revealed that all strains were associated at 82.4% similarity of coefficient (S sm ) in the dendrogram. No distinct phenons were observed, suggesting homogeneous populations of X. o. oryzae. Forty-four percent of the strains produced bacteriocin, and six bacteriocin groups were distinguished. Inoculation of X. o. oryzae strains on five IRRI differential rice cultivars (IR8, IR20, IR1545-339-2-2, Cas209, anb DV85) and three Nepalese rice cultivars (Himali, Laxmi, anb Sabitri) demonstrated significant cultivar-strain interaction
Early Effects of Organophosphate Compounds on In Vitro Intracellular Signaling and Levels of Active Neurotrophin Receptors, and on In Vivo Neurotrophin Concentrations

Organophosphorus (OP) compounds are found in household pest control products, plastics, and petroleum. Due to the neurotoxic nature of OP compounds, exposure can cause both acute and delayed symptoms, including organophosphateinduced delayed neuropathy (OPIDN). This syndrome is characterized by Wallerian-like degeneration of nerves in the central and peripheral nervous system after exposure to neuropathic OP compounds. There are many questions surrounding the mechanisms of the onset of OPIDN, including possible alterations in proteins associated with neuronal maintenance and repair. This dissertation investigated the changes in levels of neurotrophins in vivo and how in vitro levels of neurotrophin receptors and their downstream signaling cascades are affected after exposure to OP compounds. We also characterized the molecular weight of a soluble factor responsible for inducing neurite outgrowth in vitro after in vivo exposure to a neuropathic OP compound. We evaluated in vivo endpoints using enzyme-linked immunosorbant assays. Results indicated that nerve growth factor (NGF), brain derived neurotrophic factor (BDNF), and neurotrophin3 (NT-3) are found in chicken spinal cord but do not increase as a result of exposure to neuropathic OP compounds. This study also noted that NGF, BDNF, and NT-3 concentrations were not altered after exposure to a non-neuropathic OP compound. We evaluated in vitro endpoints using Western blots, ultrafiltration, and digital morphometry. These studies revealed that activated forms of high-affinity and low-affinity neurotrophin receptors are present after OP compound exposure, that the ratio of these two receptors to each other is stable after OP compound exposure, and that the activated form of the lowaffinity receptor, which can lead to apoptosis, was present in greater levels than the activated form of the high-affinity receptor. Furthermore, OP compound exposure resulted in time-dependent changes of protein levels central to the mitogen-activated kinase and phosopholipase C-γ intracellular pathways. Changes in a third pathway, the protein kinase C pathway, were dependent on the concentration and type of OP compound. Finally, in vitro neurite length was not affected by the type of OP compound administered in vivo or when a whole protein fraction was separated by molecular weight. This research has revealed in vivo consequences and early effects on intracellular protein and activated neurotrophin receptor levels after OP compound exposure. These early effects may contribute to the delayed development of neurotoxic effects associated with OP compound exposure.

The Egyptian Cardiothoracic Surgeon

Background: Untreated tricuspid regurgitation during mitral valve surgery may progress to severe symptomatic tricuspid regurgitation. Concomitant repair may increase the operative risk; however, re-operative tricuspid valve surgery is a highrisk procedure. This study's objective was to identify the predictors of DeVega repair failure in patients with functional tricuspid regurgitation and concomitant mitral valve surgery. Methods: This research is a retrospective comparative study that included 140 patients who underwent tricuspid valve repair concomitant with mitral valve replacement. We divided the patients into two groups; the first group (n=106) included patients with no DeVega failure at six-months follow-up (The sustained repair group). The second group included 34 patients who developed moderate or higher TR after the DeVega and was named the failed repair group. Results: The demographic data and comorbidities were not statistically different between both groups. The preoperative atrial fibrillation (73 (69%) vs. 30 (88%)’ p= 0.027) pulmonary artery pressure (64.8±3.6 vs. 81±6.5 mmHg; p= 0.02), right ventricular dimension (4.85±0.24 vs. 5.23±0.37 cm; p= 0.03), and time between the indication of surgery and operation (8.3 ± 3.1 vs. 14.7 ± 5.4 months; p = 0.003) were higher in patients with failed DeVega repair. There was no statistically significant difference regarding the mean bypass time, cross-clamp time, ICU and hospital stay, and postoperative complications between both groups. Predictors of failure after six months were preoperative heart failure (OR: 15.4 (95% CI: 392.3); p= 0.003), long time between diagnosis and surgery (OR: 12.3 (95% CI: 2.184.7); p= 0.007), and postoperative severe pulmonary hypertension (OR: 24.7 (95% CI: 3.1199.6); p= 0.003). Conclusions: DeVega repair is associated with a high failure rate after six months. The study of predictors of failure could change our management plans to reach the best results for repair.

Yellow Card Traps and its Effects on Population of Bemisia tabaci

The best method to trap Bemisia tabaci adults using yellow card and the control effect of yellow card's (trap on) the B. tabaci population in the cucumber field were studied, the results showed that B. tabaci has strong taxis to the yellow card. When the yellow card to trap the adults of Bemisia tabaci was used on cucumber, the best method is to hang the yellow card vertically between the rows of the cucumber plants, and the height of yellow card is almost kept the same as the top of the cucumber plant. The yellow card can also trap other insects in the cucumber field such as springtails, cucumber aphids, cucumber thrips, etc. Life tables constructed by the affecting factors in the control area and yellow card-used area have been established. In control area, the B. tabaci population trend index (I-value) is 8.63, while in the yellow card-used area, its I-value is only 3.519 8; The interference index of population control (IIPC) of yellow card's trap and kill reaches 0.407 9. The exclusive index of population control (EIPC) in yellow card-used area is 6.791 7, while in the control area, the EIPC is 6.161 7.

This paper looks at the effects of aging on the response of skeletal muscle to exercise from the perspective of the behavior of muscle precursor cells (widely termed satellite cells or myoblasts) and regeneration. The paper starts by outlining the ways in which skeletal muscle can respond to damage resulting from exercise or other trauma. The age-related changes within skeletal muscle tissue and the host environment that may affect the proliferation and fusion of myoblasts in response to injury in old animals are explored. Finally, in vivo and in vitro data concerning the wide range of signaling molecules that stimulate satellite cells and other aspects of regeneration are discussed with respect to aging. Emphasis is placed on the important role of the host environment, inflammatory cells, growth factors and their receptors (particularly for FGF-2), and the extracellular matrix. EXERCISE AND REGENERATION There are at least three possible cellular responses that can occur in muscles subjected to exercise as outlined below. Low-level “Sublethal” Damage Insufficient to Provoke Regeneration Specific forms of exercise, in particular lengthening contractions (eccentric muscle actions, e.g., those that occur when descending any incline), can result in disruption of the myofibrillar structure, especially that of the Z-bands, and also in minor membrane damage, resulting in “leakiness” of the sarcolemma. It seems that such minor or sublethal injury to myofibers can be repaired locally by rapid restoration of the wounded sarcolemnal membrane so that cellular breakdown is limited and focal necrosis does not occur. The extent to which such sublethal damage occurs after exercise is unknown. Minor damage does occur in response to modifications in muscle loading causing alterations to myofibrils and nascent sarcomere formation in myotendinous regions associated with an accumulation of macrophages. The macrophages may be specifically attracted to factors and then secrete other factors that assist in remodeling in this area, and yet this inflammatory activity at the myotendinous junction occurs without any associated myofiber necrosis and regeneration. In such situations of sublethal damage there should be no need for satellite cells (myoblasts) to undergo replication.

Phospholipid as a growth factor of Uroglena americana, a red tide Chrysophyceae in Lake Biwa.

To determine the bacterial factor necessary for the growth of Uroglena americana, a red tide Chrysophyceae in Lake Biwa, various extracts from cells of Escherichia coli were added to a temporary axenic culture of U. americana and effect on the algal growth was examined. Water extract of bacterial cells was ineffective to promote grwoth of U. americana, but chloroform/methanol extract supported good growth. After fractionation and purification of the extract, it was revealed that the active compound contained in the bacterial cells was phosphatidyl ethanolamine. Addition of highly purified commercial phosphatidyl ethanolamine resulted in an excellent growth of U. americana. This requirement was also fulfilled by the high purity natural phospholipids, indicating no specific requirement for phospholipids in U. americana. Phosphatidic acid supported good growth of U. americana but glycerophosphate (a precursor of phosphatidic acid) did not. Several glycerides and free fatty acids were not as nutritionally effective as phospholipids.
A review on recent advancements in diagnosis and classification of cancers using artificial intelligence

Artificial intelligence has illustrated drastic changes in radiology and medical imaging techniques which in turn led to tremendous changes in screening patterns. In particular, advancements in these techniques led to the development of computer aided detection (CAD) strategy. These approaches provided highly accurate diagnostic reports which served as a “second-opinion” to the radiologists. However, with significant advancements in artificial intelligence strategy, the diagnostic and classifying capabilities of CAD system are meeting the levels of radiologists and clinicians. Thus, it shifts the CAD system from second opinion approach to a high utility tool. This article reviews the strategies and algorithms developed using artificial intelligence for the foremost cancer diagnosis and classification which overcomes the challenges in the traditional method. In addition, the possible direction of AI in medical aspects is also discussed in this study.
In-vitro and In-vivo Evaluation of Anti-trypanosomal Activity of Carica papaya Seed Extracts and Fractions in Albino Wister Rats

Aims: This study presents baseline data on the In-vitro and In-vivo evaluation of anti-trypanosomal activity of Carica papaya seed extracts and fractions in Albino Wister rats. Study Design: Mention the design of the study here. Place and Duration of Study Sample: Department of Biochemistry, Modibbo Adama University of Technology, Yola, between June 2009 and July 2010. Methodology: 56 Wister rats of both sexes were randomly divided into 8 groups (I – VIII) of 7 rats each were used for this study. Four concentrations (100, 200, 400 and 800 mg/kg) of different extracts of seed carica papaya were screened for trypanocidal activity against Trypanosoma brucei In vitro and In vivo. The effect of the extracts was evaluated for trypanocidal activity in rats infected and not infected with the parasite. Administration of the extract and the drugs was orally daily for 5 consecutive days from day 7 of post infection. Level of parasitemia and body weight was taken daily for 21 days. Original Research Article Kinjir et al.; AJBGMB, 4(2): 13-25, 2020; Article no.AJBGMB. 57212 14 Results: The extracts inhibited parasite motility and totally eliminated the organisms at the concentrations used In vitro. The extract also showed promising in vivo trypanocidal activity. The observed In vitro and In vivo trypanocidal activities may be due to the presence of bioactive compounds present in the extracts as seen in this study. The extract also improved the observed decreases in haematological parameters of the treated rats, which may be due to their ability to decrease parasite load. The LD50 was estimated to be ≥2,000 mg/Kg (v/v) for acute oral toxicity test (because all the rats survived at the end of the 14-day observation period). This is an indication of very low toxicity, implying that the extract could be administered with some degree of safety. A significant decreased (p<0.05) were observed in weight of rats at 100 mg/kg, 200 mg/kg 400 mg/kg 800 mg/kg negative control and prophylactic at four to eight days of infections, while significantly increased (p<0.05) were observed in weight of rats for berenil control and normal control. Conclusion: The decrease in weight of rats could be as a result of loss of appetite due to severe fever and also the trypanosome.
©Nigerian Mathematical Society VARIANT OF FINITE SYMMETRIC INVERSE SEMIGROUP

In a semigroup S fix an element a ∈ S and, for all x, y ∈ S, define a binary operation ∗a on S by x ∗a y = xay, (where the juxterposition on the left denote the original semigroup operation on S). The operation ∗a is clearly associative and so S forms a new semigroup under this operation, which is denoted by S and called variant of S by a. For a finite set Xn = {1, 2, . , n}, let In be the symmetric inverse semigroup on Xn and fix an idempotent a ∈ In. In this paper, we study the variant I n of In by a. In particular, we characterised Green’s relations and starred Green’s relations L∗, R∗ in I n and also showed that the variant semigroup I n is abundant.

LIQUIDITY RISK AND FINANCIAL PERFORMANCE OF DEPOSIT MONEY BANKS IN NIGERIA

The Nigerian banking crisis in the post consolidation era has been attributed to risks that were not proper managed by many banks. Bank’s liquidity is one the major factors that determine success or failure of the banks in reaching its goals, and dramatic and sudden changes in the bank liquidity can lead to financial crisis and bankruptcy. This study investigated the impact of liquidity risk on the financial performance of Deposit Money Banks (DMBs) in Nigeria. Using Yamane sample size method, datawere randomly collected fromEleven(11)Nigerian bankscovering the periodof2005to2013. TheDependentvariablesusedinthisstudywasnet interest margin (NIM) as measure of financial performance while five liquidity risk proxies were used as independent variables. The study examines which of the five liquidity risk variables exert great influence on the financial performance of DMBs in Nigeria. Using correlation and ex post facto research design, it was found that there is negative relationship between four liquidity risk buckets and financial performance of DMBs in Nigeria but only total liquid assets to liabilities is significant at 1% level . On the other hand, it was found that there is significant positive relationship between total loan to total deposit as measure of liquidity risk and financial performance of DMBs in Nigeria. The study recommends that DMBs should make adequate provision for liquidity to meet up with depositors’ withdrawal demands at any given time. While shareholders and management should mindful of the bank’s policy of granting loans to customers because it will affect their liquidity position which will in turn have great impact in financial performance of DMBs
A Study on Actinorhodin-like Substance Production by Streptomyces IQ45

Production of pH-pigment (actinorhodin – like substance) was ascertained from ten Streptomyses isolates. Streptomyses IQ45 isolate was only isolated which produced pH- sensitive pigment. The production of pH-sensitive pigment was detected by fuming over ammonia. After extraction of this antibiotic, a number of physiocochemical characterizations were carried out which involved (IR, UV, MP, CHN-analysis, and solubility test). Indicated that this antibiotic is an actinorhodin-like substance. TLC of the extracted substance showed a single spot with Rf value equivalent to (0.26) which was close to that of actinorhodin. These antibiotics showed inhibitory activity against Staphylococcus aureus similar to that of actinorhodin produced by Streptomyces coelicolor A3 (2). The productivity of this antibiotics was (45 mg/L) at pH 8.5 and (40 mg/L) at pH 7 from the mycelial mat and (10 mg/L) when extracted from the liquid medium at pH7.
Effect of temperature and growth stage of wheat on development of leaf and glume blotch caused by Septoria tritici and S. nodorum

Severity of leaf blotch caused by Septoria tritici and leaf and glume blotch caused by S. nodorum was assessed on two soft red winter wheat cultivars (AGRA GR8SS and Caldwell) at three temperatures (19, 24, and 29 C) and four growth stages (GS 6 or first node visible, GS 10 or boot, GS 10.5 or preflowering, and GS 11 or postflowering). The percentage of leaf and glume area with symptoms, density of pycnidia in lesions, and number of conidia per pycnidium were determined
