Genetic Diversity of Iraqi Barley Species Differing in Their Tolerance to Drought by RAPD Analysis

The genetic diversity was studied in sixteen barley Hordeum vulgar L. species cultivated in Iraq , which are differ in their ability to drought stress tolerance by using random amplified polymorphic DNA polymerase chain reaction (RAPD - PCR ) .Barley species was evaluated to drought stress  after treatment the plant seedling at germination stages to different concentration of polyethylene glycol (PEDG6000) . The results showed that the Broaq and Arefat species have the highest tolerance to drought stress in contrast the rest of Barly species like Alkhair, Alwarkaa, Ebaa99, Shoaa, Alrafidain,Sameer Rehana 3 , forat9 , jazeral ,and ebaa7 revealed sensitivity to drought stress .      The primes which used RAPD technique for all the studied species were produced 203 bands . The percentage of monomorphic bands is 10.39 % , while the polymorphic bands scored 89.70% raning from 71.4 % for OP-B11 primer to 100% for OP-C16 primer .Some primers produced specific or distinguished bands for some Barley species , such as primer OP-N13 which produced band with 450 bp molecular weight. and this band was   appeared in sensitive drought stress species only like Forat 9 ,Jazera 1 and Ebaa7. Primer P27 produced band with 2000 bp molecular weight and this band was appeared in highest tolerance Boraq Barley species .This band maybe associated with drought tolerant.   Cluster analyses by using jaccard scale for genetic similarity revealed a dendogram with three major groups with 75% similarity degree .The first and second sub group of group one included the tolerant and moderately tolerant species excluding Alkhair and Alwarkaa species which they are separated according to their genetic origin with one of the parents (Arefat) . The second and the third groups with the third sub group of group one included the sensitive species. The results of RAPD markers indicated the presence of high percentage of genetic diversity within the studies Barley species cultivated in Iraq .Moreover .these result enable the researches to separate the samples which differ in their ability to drought stress tolerance by using few numbers of genetic sites.

The genetic inhibition of some pathogenic bacterial isolates related to Enterobacteriaceae by using Different leaves extracts of Cider (Nabag) Zizyphus spina-christa

The plant Zizyphus spina-christa grows wildly in the middle and southern of Iraq locally named Nabag. In this study the antibacterial activity of several different plant extract (alcoholic hot and cold extract 80%, aqueous hot and cold extract) was tested against some gram negative bacteria that related to Enterobacteriacea as follow; Pseudomonas aeruginosa, Escherchia coli Proteus mirabilis, Serratia mercesence,. Aeromonas sp, Klebsiella pneumoniae ,Shigella sp, Salmonella enteritidis (134), S. typhi(97), S. typhimurium (300) , S. typhi, . The results showed that efficient method of extract was alcoholic hot extract from other extract methods that are used in this study. The detection of active compound in crude extracts of the leaves show

Drought Spatiotemporal Characteristics Based on a Vegetation Condition Index in Erbil, Kurdistan Region, Iraq

     Drought is a complex phenomenon that has severe impacts on the environment. Vegetation and its conditions are very sensitive to drought effects. This study aimed to monitor and assess the drought severity and its relationships to some ecological variables in ten districts of Erbil Governorate (Kurdistan Region), Iraq, throughout 20 years (1998-2017). The results revealed that droughts frequently hit Erbil throughout the study period. The Landsat time-series- based on Vegetation Condition Index (VCI) significantly correlated with precipitation, Digital Elevation Model (DEM), and latitude. Extreme VCI-based drought area percentages were recorded in 1999, 2000, 2008, and 2011 by 43.4%, 67.9%, 43.3%, and 40.0%, respe

CALCULATION THE AIR POLLUTION TOLERANCE INDEX OF EUCALYPTUS PLANT IN BAGHDAD CITY

Air pollution from various sources is one of the most serious environmental problems, especially after pollutants are deposited on the surface of the soil and leaves of the plants and then transferred to the rest of the plant and entering food chains. The present study was conducted to determine the effects of air pollution on different biochemical parameters in Eucalyptus sp. and calculation the Air Pollution Tolerance Index. The selected plant leaves were collected from five sites, four of them within the city of Baghdad, namely Al-Jadriya, Al-Andlous, Al-Doura and close to the private generators to represent the urban areas and Abu Ghraib site to represent the rural area. The leaves were taken on a seasonal basis for the period from Octo

Serum prolactin, Preptin, CCL 18 and genetic polymorphisms in Iraqi women with polycystic ovary syndrome

The polycystic ovary syndrome is an endocrine condition. One of the leading causes of female infertility and the most common disorder among women. The work was being carried out on 100 Iraqi women (50 cases confirmed with PCOS and 50 controls). Between October 2019 and March 2020, blood samples were collected from the Advanced Institute of Infertility Diagnosis and Assisted Reproductive Technology at AL-Nahrain University and a private laboratory. ELISA was used to evaluate the biochemical parameters of preptin, FSH, insulin, LH, and CCL 18 in serum samples from the AFIAS-6 (AFIAS Automated Immunoassay System). The findings of the analysis indicate that, as opposed to the control group, values of prolactin (ng/ml), LH (mIU/ml), Preptin (

Removal of Chlorpyrifos (Dursban) Pesticide from Aqueous Solutions using Barley Husks

The removal of chlorpyrifos pesticide from aqueous solutions was achieved by adsorption using low cost agricultural residue as adsorbent surface; barley husks. Several variables that affect the adsorption were studied including contact time, adsorbent weight, pH, ionic strength, particle size and temperature. The absorbance of the solution before and after adsorption was measured by using UV-Visible spectrophotometer. The equilibrium data was suitable with Langmuir model of adsorption and the linear regression coefficient R2 = 0.9785 at 37.5°C was used to knowledge the best fitting isotherm model. The general shape of the adsorption isotherm of chlorpyrifos on barley husks consistent with (H3-type) on the Giles classification. Several

The Clinico-epidemiologic Characteristics of Iraqi Patients with Neuroendocrine Tumors and Their Response to Long Acting Octreotide

Background: The lack of studies regarding the neuroendocrine tumors (NET) is related to the rarity of these tumors .Long acting Octreotide is an established treatment for NETs by both providing symptomatic relief & inhibiting tumor growth. However, studies regarding incidence of NETs & their response to long acting Octreotide are still insufficient.
Objectives: To study the clinico-pathologic characteristics of Iraqi patients with NET & their response to long acting Octreotide.
Patients & methods: This is a cross-sectional observational study that was conducted in Oncology teaching hospital using patients’ follow-up records. Data recruitment included all NET patients diagnosed after October 2013.

Diversity has become one of the required phenomena to be available within public organizations, in light of the changes taking place in the global and international environment and in various fields. Therefore, it was imperative to study the impact of this phenomenon in various institutions, especially public ones, in most developing countries, including Iraq. The current research aims to analyze the relationship between The demographic diversity and institutional effectiveness of a sample of workers in public institutions included (500) respondents. The questionnaires were distributed to them randomly. Diversity is considered an independent variable and institutional effectiveness a dependent variable. The researcher used interview tools a
