The study's goals were to separate and identify endophytic fungi from Aloe vera leaves by looking at their morphology and molecules, as well as to find the chemical compounds in the leaf extract by using HPLC, GC, and GC-Mass instruments. The results showed that 53 endophytic fungi were isolated from a total of 120 pieces of A. vera leaves, with a total colonization rate of 44.16%. The fungus Aspergillus terreus had a colonization rate of 14.16%; Aspergillus niger had a colonization rate of 13.33%; Penicillium chermesinum demonstrated a colonization rate of 6.66%; Paecilomyces variotii had a colonization rate of 2.5%; Talaromyces radicus; and Aspergillus flavus achieved a colonization rate of 1.66%. Finally, the fungi Aspergillus quadrilineatus, Talaromyces verruculosus, Neoscytalidium dimidiatum, Alternaria solani, and Aspergillus niveus achieved a colonization rate of 0.83%. The results of examining the alcoholic extract of the leaves using the HPLC device showed the presence of the chemical compounds aloin at a concentration of 125.39 ppm and aloe emodin at a concentration of 66.59 ppm. We looked at the leaf alcoholic extract with a GC machine and found a group of fatty acids. These included linoleic, oleic, palmitic, and stearic. The GC-MS test revealed a group of active compounds, including Heptane, 1-(ethenylthio), Ethanedicarboxamide, N-allyl-N'-(2,5-dimethylphenyl), 2H-Pyran, 2-(3-butynyloxy) tetrahydro, 1,2-Cyclobutanedicarboxylic acid, 3-methyl-dimethyl ester and 4 (1H)-Pyrimidinone, 2-(propylthio). The presence of endophytic fungi from which effective enzymes or compounds can be isolated could probably have an important role in future medical and therapeutic uses. Also, the leaves of the A. vera plant have medicinal and therapeutic uses for many diseases.
This study was conducted to evaluate the activity of pomegranate (Punica granatum L.) peel powder and Pseudomonas fluorescens against Pythium aphanidermatum the causal agent of cucumber seedlings damping-off. Results showed that augmenting of pomegranate peel powder at 2%, P. fluorescens suspension contain 4×107cfu/ml, and the fungicide Previcure N at 0.5 ml/L to culture media (PDA) were inhibited the pathogen growth by 100, 100 and 72.1% respectively. Results of greenhouse experiment indicated that treatment of cucumber seeds with pomegranate peel powder, reduced pre-emergence damping-off percentage to 3.3% compared with 16.6% disease with P. fluorescens and 96.6% in control treatment (pathogen only). No significant differences were ob

The Boltzmann distribution of these branches has a maximum values at equal J approximately while the values of relative population are different. For the B1Σ+- X1Σ+ transition the branch's lines extend towards lower wavenumber. This is because (Bv'-Bv") value is negative, i.e Bv'< Bv" For B1Σ+-A1Π

To obtain these derivatives, the 5,6-O-isopropylidene-L-ascorbic acid[I] was chosen as starting material, compound prepared from the reaction of L-ascorbic acid as starting material. Compound[I] was prepared from the reaction of L-ascorbic acid with dry acetone in the presence of hydrogen chloride. The esterification of hydroxyl groups at C-2 and C-3 positions with excess ofethyl α –chloroacetate in the presence of sodium acetate produce acorresebonding ester [II] , which was condensed with hydrazine hydrate to give new hydrazide [III] .

If the personality of the child has been well organized and if the motives have been fully expressed and effectively directed, the child will have a strong will, happy self-confidence and a strong personality.

Show MoreThis study was aimed to investigate the iron overload effect on the levels of ferritin, testosterone, follicle stimulating hormone (FSH), luteinizing hormone (LH) and prolactin (PRL) in male patients with β-thalassemia. Blood levels of sex hormones and ferritin were determined in (50 males) beta-thalassemia patients, aged (16-23) years and in (30) healthy males matched for age. They were recruited from the Abin Al-Balady Hospital in Baghdad. Ichroma™ kits were used to determine the blood levels of sex hormones and ferritin. The results showed that the level of testosterone, LH and FSH were significantly (p≤ 0.05) lower in β-thalassemia male patients compared to controls.
