Abstract: The present study was carried out to assess the impact of mass bathing on water quality of Ganga River during Maha Kumbh-2010. Ganga water samples were collected from three selected bathing Ghats / Platforms of river Ganga and analyzed for some Physico-Chemical parameters. It was observed that all parameters were least affected at the Ghat / platform of Sapt Rishi Ashram, which is the least used for bathing by pilgrims and remains least disturbed zone among three sites, whereas almost all parameters were highly affected at Har- ki- Pauri, the site used most by the pilgrims and hence the highest disturbed zone.

Abstract:Yoghurt was produced from African yam bean and studied. Milk was extracted from whole and dehulled seed African yam bean seeds, pasteurized and fermented with yoghurmet (a commercial yoghurt culture of Streptococcus thermophilus and Lactobacillus bulgaricus). Microbial qualities of the yam bean yoghurt samples were evaluated to determine the microbiological quality of the products. Microbial load decreased significantly (p<0.05) with increase in storage time. Bacterial species isolated from the yoghurt samples were Lactobacillus sp and Streptococcus sp. Spoilage by yeast were also noted at room temperature.

ABSTRACT: This study aimed to determine the prevalence of HIV and TB among patients on directly observed treatment of short-course (DOTS) in Abeokuta, Nigeria. Two hundred DOTS attendees (124 males and 76 females, age range: 16 to 75 years of age) at the Department of Health Services, UNAAB were randomly recruited for this study from January 1999 to July 2010. Samples of sputum and blood were collected and processed using standard laboratory procedures. All the patients’ sera were screened for antibodies to HIV-1/2 using two rapid ELISA kits. Sputum was examined for presence of Mycobacterium tuberculosis using Ziehl-Nelson’s staining method. The results showed that of the 200 patients enrolled in the DOTS, 30 (15.0%) patients were only acid-fast bacilli positive, 3 (1.5%) were only positive for anti-HIV antibodies and none (0.0%) was positive for both HIV antibody and TB. We observed that patients ≥ 40 years had higher infection rate for TB (21.5%) and HIV antibody (3.1%). Statistically, there was no significant difference in the distribution of HIV and TB infections with respect to age (P>0.05). Males and females appeared comparable in either infection rate (P = 0.05). Students had higher infection rate for TB (16.7%) and non-student had higher rate for HIV (1.6%); these differences were not statistically significant (P > 0.05). Those in the urban area had higher infection rate for TB (17.2%) while those in the rural area had higher infection rate for HIV (1.9%). Statistically, there was no significant difference between these values with respect to residential areas. The findings of this study have further confirmed that TB and HIV infections are common in Abeokuta, an urban area of Ogun State, Nigeria.

Abstract: Companies producing hygiene products have offered a solution–sanitary, antibacterial, antimicrobial, antibiotic, wipes, and soaps to kill anything that dares to creep into our wholesome lives. These salves will cure us of the demons that dare to grow near us. Antimicrobial hand gel sanitizers provide a greater bacterial reduction than others. However, the link between greater bacterial reduction and a reduction of disease has not been definitively demonstrated. Confounding factors, such as compliance, composition, and frequent use, may all influence the outcomes of studies. Therefore, this research addresses the challenge of improving hand hygiene through using non alcoholic hand gel sanitizers.The antibacterial efficacy of these products was to be evaluated and compared through studying the response of organisms to cleaning regimens in healthcare settings using different responses of various hand gel sanitizers that are sold in Saudi market in Jeddah.

Abstract: To ascertain the prevalence of dental caries and oral lesions among HIV infected patients in Enugu and Calabar towns in Nigeria, the oral cavities of one hundred and sixty (160) HIV positive and negative patients were examined. Oral ulcers (73.8%) and Oral Candidiasis (67.5%) were the most prevalent Oral manifestation among the HIV positive patients studied, while Non-Hodgkins lymphoma (5%) and Hairy leucoplakia (17.5%) were the least. Other oral manifestations observed among the HIV positive patients include: Angular Chelitis (25%), Peridontitis (33.8%), Oral Kaposi sarcoma (18.8%) and Acute necrotizing ulcerative gingivitis (21.3%). It was however, observed that dental caries occurred more among HIV negative patient (33.8%) than the HIV positive patients (22.5%). Whereas Oral manifestations occurred generally low among the HIV Negative patients, Non-Hodgkins lymphoma and Hairy leucoplakia were completely absent among the HIV Negative patients studied. With the exception of dental caries and Angular Chelitis, Oral manifestations occurred more among males than females. It was also noted that Oral manifestations among HIV positive patients reduced with increase in the level of education of the patients. This study indicate high level of Oral manifestations among HIV positive patients in Enugu and Calabar towns in Nigeria, and thus advocate for the incorporation of oral examination as part of the general physical exam for HIV positive patients in Nigeria.

Abstract: There are two major types of lymphoma: Hodgkin’s lymphoma and non- Hodgkin’s lymphoma. Hodgkin’s lymphoma (HL) tends to affect younger patients and be relatively curable, whereas non- Hodgkin’s lymphoma (NHL) tends to affect older patients and carry a worse long-term prognosis as a group. Antioxidants are molecules that can neutralize free radicals by accepting or donating an electron to eliminate the unpaired condition. One of these antioxidant molecules was reduced glutathione (GSH) that can reduce free radicals by hydrogen donation. Also, superoxide dismutase (SOD) is one of the most important natural antioxidant enzymes manufactured in the body provide an important defense against free radicals, that converts two superoxide radicals into one hydrogen peroxide and one oxygen. Malondialdehyde (MDA), the end product of lipid peroxidation (LPO), arising from the free radical degradation of polyunsaturated fatty acids, can cause cross-linking in lipids, proteins and nucleic acids. Our study aimed to detection of GSH, SOD and MDA as prognostic biomarkers associated with lymphoma patients in a population from Damietta, Egypt. This hospital-based case-control study was conducted during (2007-2010); 50 lymphoma cases and 14 controls were enrolled. Information was collected and blood samples were obtained and parameters were determined by standard techniques. Associations between variables of interest and non-Hodgkin, Hodgkin Lymphoma(NHL, HL) were assessed using conditional logistic regression. We found that at initial diagnosis of NHL patients, GSH was negative for all patients (100%) and remain negative after treatment applied with cut-off value (2.09 X10 m Mol/L cells). Also, SOD was negative for all patients (97.1%) before treatment applied except one case ( 2.9%) was positive. It still negative (100%) after treatment applied with cut-off value (33.95%). On the other hand, MDA was positive for patients (94.3%) and negative for patients (5.71%). Then, it was positive for patients (73.7%) and negative for patients (26.3%) after treatment applied with cut-off value (0.53 X10 Mole / mL packed cells). On the other side, at initial diagnosis of HL, GSH was negative for all patients (100%) and remain negative after treatment applied with cut-off value (2.09 X10 m Mole/L cells). Also, SOD was negative for patients (93.3%) before treatment applied except one case ( 6.7%) It still negative (100%) after treatment applied with cut-off value (33.95%). On the other hand, MDA was positive for patients (100%). Then, it became positive for patients (83.3%) and negative for patients (16.7%) after treatment applied with cut-off value (0.53 X 10 Mole / mL packed cells). These findings suggest that MDA level was elevated in NHL and HL patients, before and after treatment on comparison to that of controls. But SOD, GSH levels were decreased before and after treatment at all.

Abstract: Background: Despite the high prevalence of both human papillomavirus (HPV) infections and cervical cancer ,the ability to test for HPV infection of the uterine cervix is limited by a lack of an easy sample collection method that does not require gynecological examination. This study was done to evaluate urine sample as an alternative easily obtained, non-invasive sample for the diagnosis of HPV cervical lesions. Patients & Methods: This study was carried out on 40 female patients who were divided into two groups: Group I: comprised 30 female patients with HPV related cervical lesions (flat condyloma) (histologically diagnosed in bunch biopsy). Their ages ranged from 21 to50 years (mean=35.812.4). Group II: comprised 10 female patients complaining of symptoms or have a colposcopic picture similar to that of flat condyloma but were negative for HPV changes by histological examination. Their ages ranged from 23 to 46years (mean=32.78.2).For the 40 subjects of the study, detection of HPV-DNA in urine samples was done using nested real time PCR. Results: HPV-DNA was detected in urine of 66.7% of HPVpathologically positive cases (group I) and 30% of HPVpathologically negative cases (group II). detection of HPV DNA in urine samples significantly correlated to the diagnosis by pathological examination (p=0.042). Also HPV-DNA was detected in urine of 75% of age group 20-40 years in group I, and in urine of 100% of the same age group in group II. This rate is higher than theother age groups. However no statistical significance was found. Conclusion: Urine being easy non-invasive sample, acceptable by most of people, may allow rapid screening and diagnosis of HPV infection. It can also be valuable in follow up of women with cervical dysplasia.Urine as an easy non-invasive sample ,acceptable by most of people, will allow the diagnosis of HPV infection.without need for pelvic examination and invasive samples either for Pap testing or biopsy taking. Also urine testing for HPV-DNA may be used for epidemiologic purposes especially in population where it may be difficult to obtain genital specimens for religious or cultural reasons or in children or young adolescents especially before vaccination.It can also be valuable in follow up of women with cervical dysplasia.

Abstract: Genetic relationships between twenty Mulberry varieties were assayed with Random Amplified Polymorphic DNA (RAPD) and Inter Simple Sequence Repeats (ISSR) markers, which distinguish individuals, as well reflect the inherent variation and inter-relationships among the varieties. Sixteen decamer RAPD primers and 8 ISSR primers were used in the present study. Over 70 reproducible bands were generated by RAPD primers, out of which, 61 polymorphic bands were identified, conferring 81.3% polymorphism. Similarly 43 polymorphic bands were produced by ISSR primers, out of which, 42 polymorphic bands were identified conferring 97.6% polymorphism. All the primers produced typical banding in each of the cultivars, suggesting the applicability of this test in cultivar identification. Most of the individuals of the test exhibited to have unique molecular genotype. Population genetics structure analysis of these varieties further revealed high genetic differentiation coefficients (GST), the heterozygosity among population (Ht) showed with low gene flow (Nm) when 5th cluster was paired with other genotypes. On the basis of these parameters and the results of clusters analysis, it is concluded that three genotypes can be considered as a separate group of mulberry, whereas the other four clusters may be grouped separately. A dendrogram was constructed using Wards Euclidean distances and UPGMA method. Based on the number of bands, the genotypes were grouped to form 5 clusters.

Abstract: This is an intervention study aimed to studying the effect of counselling on couples adjustment to failed assisted reproductive technology .It was conducted at IVF centre of Ain Shams Maternity University Hospital after obtaining faculty ethical committee approval. The sample was consisted of (110 couple: failed cases 59 and success cases 51). Tools used for data collection consisted of Couples' Structured Interviewing Questionnaire, Coping Strategy Stress Scale, Ways of Coping (WOC) Questionnaire, follow up card and PLISSIT Model for counselling program. Results revealed that couples included in the study ranged between 20-45 years, with a mean age of 30.36 3.112 years for wives and 35.643.852 years for husbands. 67.3% of female were the cause of infertility, and 94.5% of couples had a previous trials of ART. Women have more (personal, social and marital) stressful experiences than men. While they both frequently use a combination of strategies to cope, study showed different coping behaviours to deal with their infertility (meaning-based coping & passive avoidance coping strategy), Husbands scores were significantly lower than before counselling with regard to passive avoidance strategy with t= 2.29, and wives scores were significantly higher than before with regard to meaning-based strategy with t= 4.28. The study concluded that counselling effective on couples' adjustment to failed assisted reproductive technology. The study recommended establishment of educational programs to enlighten infertile couples about treatment options and answer their questions and different coping strategies with failed assisted reproductive technology trials.

Abstract : Recently Nature announces: neutrino travelled faster than light. Out of which arise astonishment and disbelieve drastically. We believe that the data of the experiment is reasonable, and so is trusty. But the conclusion is the result of mistake. Because: (1) the neutrino speed is: ‘c+6km/s’; (2) by Schwarzschild solution, the light speed is c(1-2GM/rc^2), and so at the surface of the earth is ‘c-42km/s’;(3) here We show, the light speed is ‘c*sqrt(1+2GM/rc^2)’, and so at the surface of the earth is ‘c+21km/s’.There for, the neutrino speed ‘c+6km/s’ is faster than the ‘c’, and so really it is the ‘super c speed’. But at the same gravitation potential well, the real light speed ‘c+21km/s’ is also faster than the neutrino speed ‘c+6km/s’ ,and so the neutrino speed isn’t the ‘super velocity of light’. This result of this experiment testified authoritatively that: (1) General theory of relativity is the result of three disfigurements! (2)Our theory of time-space & gravitation is tally with the facts. (3) Neutrinos have rest mass, and so its velocity must slower than light speed.

Abstract: Syphilis is a multifaceted disease with serious implications for the pregnant women and the unborn foetus. Treponema pallidum, the causative agent of syphilis has been a public health challenge for centuries. Sexually transmitted infections (STIs) and HIV/AIDS are widespread in the developing countries, and constitute a major public health problem in Sub- Saharan Africa. Information regarding the prevalence of syphilis in Pregnant Nigerian women is scanty from the South-west zone of Nigeria. One thousand two hundred and fifty six pregnant women, who attended the antenatal clinic of the Federal Medical Centre, Abeokuta, Nigeria from January 2011 to December, 2011 were screened for syphilis using Venereal Disease Research Laboratory (VDRL) reactive technique. Seropositive samples were confirmed using immunochromatographic test strips which are specific for Treponema pallidum. The results showed that 4(0.32%) of the 1,256 pregnant women were positive for antibody to Treponema pallidum. The serodynamic of Treponema pallidum in relation to age showed an increase in infection rate of 4.0%, 0.26% and 0.17% among pregnant women in age groups of 36-40, 26-30 and 31-35 years respectively, while 16-20, 21-25, 41-45 and 46-50 years age groups had a zero percent prevalence of the organism. This study has further provided information on the prevalence of Treponema pallidum among pregnant women in Abeokuta, Nigeria.

Abstract: Selecting the right technology is always a difficult task for decision-makers. Technologies have varied strengths and weaknesses which require careful assessment by the purchasers. The purpose of this paper is applying a new integrated method to technology selection. Proposed approach is based on fuzzy AHP and Interval TOPSIS methods. FAHP method is used in determining the weights of the criteria by decision makers and then rankings of technologies are determined by Interval TOPSIS method. A numerical example demonstrates the application of the proposed method.

Abstract: Loquat (Eriobotrya japonica Linda L) is a fruit with high market value in Egypt with little details about its quality characteristics. The physicochemical characteristics of loquat fruit indicated that it contained higher total soluble solids 11.0 Brix, lower Ascorbic acid and can be considered as a good source of β-carotene. Brix lower ascorbic acid, loquat can be considered as a good source of B-carotene. Loquat fruit gave 86.32%, moisture, 5.53 mg/100g ascorbic acid and is a good source of mineral like phosphorus, iron, potassium, magnesium and calcium. Processed products jam; jelly and juice were prepared and assessed for their nutritive quality and acceptability.Results indicated That total soluble solids of jelly, jam and juice were 15, 76 and 13 Brix, respectively and that loquat juice contained more amount of ascorbic acid (4.28 mg\100g) and B –carotene (9.75 g\100g) compared to jelly and jam. Sensory evaluation of processed products showed good acceptability. Loquat jam had higher for color and flavor while loquat juice taste and consistency recorded highest total score.

Abstract: This study was undertaken to investigate the antifungal activities of naturally occurring compounds namely; thymol, eugenol, methyl cinnamate, linalool and 1,8-cineol against some economically important phytopathogic fungi in the Egyptian environment. The LC25 and LC50’s of the tested compounds against R. solani, S. rolfsii, B. cinerea, F. oxysporum and A. solani were determined according to the relationship drawn between the logarithm of concentration and the percent of growth inhibition (ldp lines), and the toxicity indexes and relative potencies were calculated. Thymol was the most effective compound followed by eugenol, methyl cinnamate and linalool against R. solani, F. oxysporum and B. cinerea whereas the thymol followed by methyl cinnamate, eugenol and linalool were the most effective compounds against S. rolfsii and A. solani descendingly. The LC50’s of thymol against S. rolfsii, R. solani, B. cinerea, F. oxysporum and A. solani were 107.39, 59.28, 46.60, 81.89 and 156.41 g/ml, respectively where the LC50’s of eugenol were 254.47, 95.58, 270.47, 214.74 and 414.13 g/ml and the LC50’s of methyl cinnamate were 216.3, 102.78, 288.55, 290.66 and 192.37 g/ml, respectively. The 1,8-cineol compound didn’t show any fungicidal activity.
