A Mechanism using the Electronic Signature to Verify the Power of Attorney and the Requested Activity

The rapid development that accompanies computer and information technology imposes its applications on all societies in general and developed coun tries in particular. In this paper, we present an algorithm to apply the electronic signature to verify the credibility of power of attorney and the credibility of activity requested using power of attorney. The verification algorithm is to be used in cour ts of law; the algorithm ensures a credible approval by the owner to the agent who has the power of attorney to submit the activity under concern. Selling a real estate property is an example of an activity which might be con ducted by the agent using the " power of attorney". This system, which we designed, implemented and tested, takes into consideration all the financial and security information needed. Our system requirements adopted the financial requirements such as banks and financial firms in number o f societies and countries such as the United States, the European Union and Jordan

FREQUENCY OF INTESTINAL PARASITIC INFECTIONS AMONG SCHOOLCHILDREN IN IBB CITY-YEMEN

Objectives:  Intestinal parasitic infections are widely distributed and remain one of the most health problems in Yemen. This is a cross-sectional study aimed to determine the prevalence of intestinal parasitic infection and associated factors among schoolchildren in Ibb City, Yemen. Methods:  A total of 300 stool samples were collected from schoolchildren between January to April 2018 and examined by direct smear and formalin ether concentration techniques. Results:  The result showed that 62.7% were positive for intestinal parasites, with a higher frequency of single than multiple infections (85.1 vs. 14.36%, respectively). Also, 85.64% were infected by protozoa whereas 14.36% infected by helminths. The prevalence of infection was 61.70% for Entameba histolytica, 23.94% for Giardia lamblia, 7.45% for Ascaris lumbricoides, 4.3% for Hymenolepis nana, and 2.61% for Enterobius vermicularis. Moreover, the highest prevalence of E. histolytica, G. lamblia, and A. lumbricoides was within group aged 9-12 years. H. nana was between age groups of 9-12 and 13-16 years while E. vermicularis was found among 5-8 and 9-12 years. In addition, females were 69% infected significantly higher than males 54.55%. Besides, the various signs and symptoms associated with intestinal infections have been documented. Conclusion:  High prevalence of intestinal infection was documented among schoolchildren drinking from cistern water, poor hygiene practices, poor food sanitation, non-swimming, and non-previously treated for Schistosoma parasite. High frequency of intestinal parasitic infection between schoolchildren in the study area requires more effort to implement the appropriate programmers that warrant to control and prevention the prevalence of intestinal parasitosis.                         Peer Review History: Received 1 March 2020; Revised 7 April; Accepted 3 May, Available online 15 May 2020 Academic Editor: Ahmad Najib, Universitas Muslim Indonesia,  Indonesia, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Maximising the efficiency of surveillance for COVID-19 in dialysis units in South Africa : the case for pooled testing

The COVID-19 epidemic in South Africa (SA) is currently in a growth phase with high incidences in most major cities. Patients who are dependent on chronic renal dialysis care, including peritoneal dialysis and haemodialysis, are chronically unwell and usually have multiple comorbidities including hypertension, diabetes and cardiovascular disease. These comorbidities are known to increase the risk of adverse outcomes for COVID-19, including hospitalisation with high care or intensive care admission, and/ or death. Haemodialysis patients throughout the country require facility-based support three times a week, and a typical dialysis visit is ~4 hours.The National Research Foundation of South Africahttp://www.samj.org.zaam2021Medical Microbiolog

VULVOVAGINAL CANDIDIASIS PREVALENCE AMONG PREGNANT WOMEN IN DIFFERENT HOSPITALS IN IBB, YEMEN

 Background and aims: Candida species are opportunistic yeasts that affect the genital urinary tract that causes vulvovaginal candidiasis in the most females, particularly in developing countries. This work aims to find the prevalence of vulvovaginal candidiasis among pregnant women in Ibb, Yemen. Material and methods: Two hundred and eighteen samples of females attending outpatient obstetrics and gynecology clinics were chosen from several hospitals (Al-Thawra, Maternity and Childhood Center, Maternal Reproductive Health Center, and Nasser General Hospital) located in Ibb, from December 2019 to March 2020. The laboratory works were performed in the microbiology department of Al-Thawra Hospital, Ibb. Vaginal swabs were cultivated on Sabouraud dextrose agar, then the species of Candida identification and anti-fungal sensitivity tests were performed regarding the standard procedure of microbiology. Results: The findings revealed that out of 218 cases, 134 (61.5%) were infected with Candida species, and the rate of candidiasis was higher among women coming from rural areas than among women in urban areas; and in the age group 28-37 years. C. albicans (61.2%) were the most prevalent species followed by C. tropicalis (21.64%), C. glabrata (11.19%), and C. kefyr (5.97%). Susceptibility tests showed that the most isolated Candida species were sensitive to nystatin (94.8), fluconazole (91.04%), amphotericin B (88.80%), voriconazole (78.35%), clotrimazole (75.37%), ketoconazole (73.13%), and itraconazole (69.40%). Conclusion: It can be concluded that Candida vaginitis is very common among pregnant women, and the tested anti-fungal agents continue to be effective against all isolates of Candida species. In contrast, there was a slight increase resistant against itraconazole, ketoconazole, clotrimazole, and voriconazole which raises concern about a rise in Candida species that are resistant to these drugs.                    Peer Review History: Received 27 June 2020; Revised 15 July; Accepted 12 August, Available online 15 September 2020 Academic Editor: Dr. Muhammad Zahid Iqbal, AIMST University, Malaysia, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system.

Allergenicity of latex rubber products used in South African dental schools

Background: Allergens from latex products in healthcare settings have been known to trigger latex induced allergic reactions in healthcare workers (HCWs). There is a need to quantify individual latex allergens in products in order to assess the allergenicity of latex products used in health care settings, so as to minimize the risk of sensitisation to these proteins. Methods: Fourteen latex examination gloves representing six brands (powdered and non-powdered) and five dental rubber dams from five dental academic institutions were analysed for latex allergens and total protein. Total protein content was determined using the BIORAD DC protein assay kit and natural rubber allergen levels using a capture ELISA assay specific for hev b 1, hev b 3, hev b 5 and hev b 6.02. Results: Hev b 6.02 was found in higher concentrations than other NRL allergens in the products analysed. Hev b 5 content ranged from 0 to 9.2µg/g and hev b 6.02 from 0.09 to 61.5µg/g of sample. Hev b 1 levels were below the detection limit (DL) for 79% of the samples (15/19). Dental dams showed higher allergen levels (median: 80.91µg/g) in comparison to latex gloves (median: 11.34µg/g). Powdered rubber samples also showed higher allergen levels (median: 40.54µg/g) compared to non-powdered samples (median: 5.31µg/g). A statistically significant correlation was observed between total protein and total allergen (r=0.74, p<0.001) concentrations. Conclusion Natural rubber latex (NRL) allergen concentrations differ significantly by product and brand. This study has demonstrated that NRL allergens in latex containing products used in South African dental institutions are present at sufficiently high levels to pose an allergic health risk

Common HLA Alleles Associated with Health, but Not with Facial Attractiveness

Three adaptive hypotheses have been proposed to explain the link between the human leucocyte antigen (HLA) genes, health measures and facial attractiveness: inbreeding avoidance, heterozygote advantage and frequency-dependent selection. This paper reports findings that support a new hypothesis relating HLA to health. We suggest a new method to quantify the level of heterozygosity. HLA heterozygosity did not significantly predict health measures in women, but allele frequency did. Women with more common HLA alleles reported fewer cold and flu bouts per year, fewer illnesses in the previous year and rated themselves healthier than women with rare alleles. To our knowledge, this is the first study to show a positive correlation between HLA allele frequency and general health measures. We propose that certain common HLA alleles confer resistance to prevalent pathogens. Nevertheless, neither HLA heterozygosity nor allele frequency significantly predicted how healthy or attractive men rated the female volunteers. Three non-mutually exclusive explanations are put forward to explain this finding
