No full textCataglyphis laylae Collingwood nov. spec. Plates 96–103 Cataglyphis desertorum Forel, 1894, teste Collingwood, 1985; unavailable name according to Agosti (1990). Specimens examined: Holotype: 1 ☿, United Arab Emirates, al-Ain [24°13'N 55°46'E], iii.1995, leg. C.A. Collingwood (MHNG). Paratypes: 3 ☿, al-Ain zoo, 13.iii.2005, CAC. 1 ☿, Remah, 9.iii.1995, CCA. 3 ☿, Remah, resthouse, 250 m, irrigated sand dune [24°10'37"N 55°18'6"E], 18.iii.1995, leg. D. Agosti. 6 ☿, Remah, resthouse, 250 m, irrigated sand dune, nest with one entrance, [24°10'37"N, 55°18'6"E], 18.iii.1995, leg. D. Agosti. 1 ☿, Sharjah Desert Park, 5–6.x.2004, AvH; 1 ☿, 3.iii.2005, CAC. 1 ☿, al- Za'aba, 100 m, sandy soil with Rhaisa stricta [23°43'20"N, 55°33'49"E], 22.iii.1995, leg. D. Agosti. Description: A large worker from al-Ain was selected as holotype. The measurements are as follows: total length 8.40; head width 3.60; head length 4.20; scape length 3.84; funicular segment I 0.40; funicular segment II 0.23; petiole length 1.10; petiole width 0.72. Colour dark reddish brown. There are no exterior hairs on the scapes or hind tibia. The gaster, petiole and propodeum have dorsal hairs. Remarks: This species thought to correspond with C. desertorum has to be described as a new species. In fact it is one of the commonest Cataglyphis in southern Arabia. The main distinguishing feature compared with other dark Cataglyphis is the slender petiole, which has the anterior face more sloped than in other similar species such as C. niger (André, 1882) and C. savignyi (Dufour, 1862). Biology: Cataglyphus laylae nov. spec. does not appear to occur in open sandy desert and is most abundant in disturbed habitats such as man-developed plantations and open cultivated fields. Distribution: This species was recorded by Collingwood (1985) as C. desertorum from Saudi Arabia and Oman and as Cataglyphis spec. by Collingwood & Agosti (1996). Etymology: The new species is named after a village settlement called “Layla”, just north of Riyadh (Saudi Arabia) in the area where the author (CAC) first encountered it in numbers in an Acacia plantation.Published as part of Cedric A. Collingwood, Donat Agosti, Mostafa R. Sharaf & Antonius van Harten, 2011, Order Hymenoptera, family Formicidae, pp. 1-70 in Arthropod fauna of the UAE 4 on page 54, DOI: 10.5281/zenodo.116858
Antioxidants containing selenium impact on unexplained oligohydramnios
No full textABSTRACTBackground: Oligohydramnios is a significant morbidity during pregnancy that may affect fetal growth and functions and the presented work was an effort to test the addition of selenium for the correction and regaining normal liquor.Methods: Cases recruited from those attending Zinat al-Hayat hospitals and diagnosed with unexplained oligohydramnios after exclusion of prom postdates pregnancy induced hypertension Then final 100 cases divided into two groups group one control: 50 controls that followed healthy diet and a positive mindset only group two cases: 50 who followed healthy lifestyle plus adding selenium ace tablets once daily. Cases and controls followed by ultrasound evaluation with calculation of AFI and fetal weight.Results: Regarding improvement in amniotic index to be more than 5, there were 40 cases out of 50 in cases compared to 25 in controls with p=0.001 a high statistical difference that signified positive impact on the amount of amniotic fluid, regarding amniotic fluid particle diameter it was present in 22 out of 50 in controls compared to 8 only in cases with p=0.002,Regarding birth weight of, more than 2500 gm. there were 20 out of 50 in controls compared to 35 out of 50 in cases with intervention and p=0.002. Regarding APGAR score below 6 there were 15 in controls compared to only 3 in cases with p=0.001, regarding neonatal incubation there were 10 in controls compared to one in selenium group with p=0.004.Conclusions: adding selenium ace tablets in cases of unexplained oligohydramnios had a promising result and a positive impact on amniotic fluid index and neonatal outcome
Ultrasonic predictors of good ovarian response in infertile poly cystic ovarian disease patients
No full textBackground: Polycystic ovaries is a common endocrinal ovulatory dysfunction; the presented work presented a ultrasonographic predictor markers with scoring system to predict pregnancy rate in PCO.
Methods: The presented work is controlled trial comparing two different sets of uterine and ovarian ultrasound markers, done at Zinat Alhyat hospital in Benha Egypt. 100 participants divided into two groups induced for ovulation with minimal stimulation protocol in both, 6 different ultrasonic parameter calculated after induction of ovulation in known PCO patients, Group one with collective ultrasound score more than 6,Group two with ultrasound marker score of less than 6.
Results: Regarding the chemical pregnancy when HCG become more than 25 there were 40 out of 50 chemically pregnant in comparison to 25 out of 50 in the second arm with score less than 6 and a p value of 0.001 and a statistically significant difference ,Regarding the clinical pregnancy rate there were 35 cases with proved gestational sacs by ultrasound out of 50 in group one with score more than 6 compared to 18 cases out of 50 in the second group and p value of 0.0007 which was a high significant difference. Regarding miscarriage rate there were one 1 cases out of 35 in group one compared to 5 aborted cases out of 18 in group 2 with p value of 0.006.
Conclusions: Certain ultrasonic parameters 3 ovarian and 3 uterine can be highly correlated with ovulation and pregnancy rates in infertile PCO patients.

Thus, our study will propose an analysis of the ideological and historical dimension of this text representative of the literary experience of the author, then at the end the questioning of his human and moral values
Green Synthesized of Thymus vulgaris Chitosan Nanoparticles Induce Relative WRKY-Genes Expression in Solanum lycopersicum against Fusarium solani, the Causal Agent of Root Rot Disease
No full textFusarium solani is a plant pathogenic fungus that causes tomato root rot disease and yield losses in tomato production. The current study’s main goal is testing the antibacterial efficacy of chitosan nanoparticles loaded with Thyme vulgaris essential oil (ThE-CsNPs) against F. solani in vitro and in vivo. GC-MS analysis was used to determine the chemical constituents of thyme EO. ThE-CsNPs were investigated using transmission electron microscopy before being physicochemically characterized using FT-IR. ThE-CsNPs were tested for antifungal activity against F. solani mycelial growth in vitro. A pot trial was conducted to determine the most effective dose of ThE-CsNPs on the morph/physiological characteristics of Solanum lycopersicum, as well as the severity of fusarium root rot. The relative gene expression of WRKY transcript factors and defense-associated genes were quantified in root tissues under all treatment conditions. In vitro results revealed that ThE-CsNPs (1%) had potent antifungal efficacy against F. solani radial mycelium growth. The expression of three WRKY transcription factors and three tomato defense-related genes was upregulated. Total phenolic, flavonoid content, and antioxidant enzyme activity were all increased. The outfindings of this study strongly suggested the use of ThE-CsNPs in controlling fusarium root rot on tomatoes; however, other experiments remain necessary before they are recommended

No full textOral itraconazole combined with local isoconazole in the treatment chronic candida vulvovaginitis
No full textBackground: Chronic vulvovaginal candidiasis is a major problem and common with poor quality of life from itching and discharge and it is difficult to treat because fungi are slow growers.Methods: Two hundred cases recruited from JAM clinic in Benha city, Egypt divided into two groups to study combination of oral itraconazole and local isoconazole in comparison with the use of local isoconazole only in chronic monilial vulvovaginitis and main outcome was relief of symptoms and signs with absent laboratory evidence of monilial infection by culture. Group one included 100 cases treated with combined oral itraconazole with three alternate days dose of local isoconazole (gynotrazonagen) and group two (local isoconazole only) included 100 cases treated with local isoconazole ovules on alternate days for 3 doses and week period.Results: Regarding the cure rate there were 90 clinically cured rate in the combined group compared to 70 in the local treatment group with p value of 0.0004 which was a very high statistically significant difference. Clinical cure included alleviation of the symptoms of discharge dysuria dyspareunia burning itching with also by clinical examination cure and disappearance of redness erythema edema fissures with absent pseudomycelia by microscopic examination. Usually, a symptom score of less than 2 is a positive one. Regarding the laboratory cure which means absent or negative candida culture on Sabaraud agar medium there were a laboratory cure rate of 84 out of 100 in the combined treatment group compared to 65 out of 100 in the local treatment group with p value of 0.002 and a high statistically significant difference.Conclusions: Oral itraconazole combined with local isoconazole is highly effective in treating chronic monilial vulvovaginitis
