Abstract

Background vitamin D has characteristics features of a hormone, and accordingly vitamin D is a pro-hormone, rather than a true vitamin. Active form of vitamin D is binding to vitamin D receptors (VDR) then started its main action inside the body. This study is aimed to compare concentration of vit. D in a patients with diabetes mellitus, and healthy Iraqi women and its correlation with seasonal variation, and age.Subjects and methods This study was conducted in the first of August 2017 till the first of April 2018, at the outpatient unit in especial private hospital at karbalaa city in the south of Iraq. 163 women have been enrolled in present study. The sample was divided into 3 groups in both diabetic and non-diabetic subjects. Results the distribution of subjects in this study, 163 persons participated as a sample in a present research; 82 subjects are normal healthy women as controls, while 51 women suffering from non-insulin dependent diabetic mellitus, (T2DM), and 30 pregnant women suffering from gestational DM, (GDM). Stander deviation and mean of Vit. D levels in a non-insulin dependent diabetes mellitus and normal healthy women. There is significant reduction in the levels of vit.D that measured by using sera of women patients suffering from T2DM, (12.97 ± 8.9) as compared with control subjects, (18.95 ± 7.1). Conclusions the present study conclude that, the measurement of vit.D are significantly reduced when measured in women patients with non-insulin dependent diabetes sera, as compare to healthy subjects and also reduced in the sera of women patients suffering from GDM, as compared with control subjects.

المقدمة: فيتامين D هو هورمون ستيرويدي ينتج في الجلد من خلال تحويل الكولستيرول تحت تأثير الأشعة الفوق البنفسجية, يوجد فيتامين D ايضا في بعض الأطعمة ومنتجات الالبان. فيتامين D2 و فيتامين D3 يتواجدان في بعض الأغذية.تهدف هذه الدراسة الى المقارنة بين مستويات فيتامين D في مرضى السكري والمرضى الغير مصابين بالسكري من النساء العراقيات ودراسة العلاقة بين مستويات فيتامين D وفصول السنه وكذلك تغيرها مع تغير عمر المشاركين في الدراسة.هذه الدراسة تم تصميمها والبداية بها في بداية شهر آب من عام 2017 واستمرت حتى الاول من نيسان عام 2018 في وحدة الاستقبال للمرضى الخارجيين في احد المستشفيات الخاصة في مدينة كربلاء جنوب العراق. شارك 163 من النساء في هذه الدراسة وقد تم تقسيمهم الى ثلاث مجاميع سواء في مرضى السكري وغير المصابين بالسكري. تم توزيع المشاركين في هذه الدراسة وعددهم 163 من النساء الى 82 امرأه سليمه بينما 51 امرأه كانت مصابه بداء السكري من النوع الثاني وثلاثون امرأه حامل مصابات بسكري الحمل. المعدل والانحراف المعياري لتركيز فيتامين دي يبين وجود نقصان مهم في مصل المرضى الذين يعانون من داء السكري الثاني بالمقارنة مع مجموعة السيطرة.نستنتج من هذه الدراسة بأن مستويات فيتامين D قلت بشكل كبير في النساء المصابات بداء السكري الثاني وكذلك النساء الحوامل بالمقارنه مع مجموعة السيطرة.

Abstract

Analysis of the jet stream is diagnostic over Baghdad for period studies 2012 to 2014 using Radiosonde data and synoptic charts. The source of data is the Iraq Meteorological Organization and Seismology (IMOS). The most frequent occurrences of a jet stream are in April and July at 500 hPa equal to 13 times, at 300 hPa the highest frequency of the jet stream is in May equal to 14 times. This study showed that the incidence of jet streams became fluctuating, increasing and decreasing, as the least occurrences were in 2012 and gradually increased in 2014, when the highest incidence of jet streams was recorded in 2014. The most prominent results of the current jet current determination used by the synoptic maps through the fulfillment of all conditions or the fulfillment of part of the conditions. In the event that all conditions are met due to the expansion of the Hadley cell when it hits the middle condition. The results were produced if some conditions were met and in most study cases that the jet stream formed over Europe and continues to move until it reaches the Mediterranean Sea, then there will be a crossroads either over Turkey and it will be strong and in the case of growth or heading towards Iraq, in this case, it will be weak and in Decay condition.Keywords: Seasonal variation, Jet stream, Climate variation

Abstract

Seasonal variation of phytoplankton community was studied in Euphratesriver at Al Musayab city. This study was carried out at two stations from 2/ 1/ 2009 to31/ 12/ 2009. Water sample was collected bimonthly to measure: water temperature,PH, salinity and calcium ions concentration, besides identify and the count ofphytoplankton groups. The results showed that water temperature ranged betweenه 11.5 c in January and ه 32 c in August. PH ranged between 7.05-8 while salinityranged between 2.49 1.02 ppt. Calcium ions concentration was between 128.5 48.1mg/ l. 80 species belonged to 42 genus of phytoplankton were recorded at the twostations, including 59 species of diatoms (Bacillarophyta) followed by chlorophyta(13 specie) and Cyanophyta (6 species) and species for both Euglenoaphyta andPyrrophyta. The highest occurrence of species was recorded in fall (49 species ) whilethe lowest was recorded in winter (35 species).The species includes: Occurredthroughout all year seasons.Chlorella vulgaris, Aulacoseira granulata¤ Cyclotella menenghiniana¤ Achanthesminutissima¤ Cyclotella ocellata ¤ Diatoma vulgare ¤ Cymbella cistula ¤ Cocconeispedicul¤ Fragilaria acus¤ Fragilaria ulna¤ Fragilaria ulna var biceps¤ Naviculacryptocephala , Nitzschia palea.The results showed that there was a peak of phytoplankton density in spring (67.8x10ᴈ cell / L) while the lowest density recorded in summer (30.4 x 10ᴈ cell / L). Theresults appeared that there was a decline in phytoplankton density ranged between 2-3times compared with the results in 2002 and 2003 in the same location. Asconclusions, the density of phytoplankton affected by environmental factorsthroughout the seasons of year, besides the occurrence of Zebra mussel in the twostations.

Abstract

Abstract:Background: It was found that the occurrence of Guillain-Barre Syndrome (GBS) varies in respect to the month and season; this variation has not been adequately studied.Objective: To determine the month and seasonal variation of GBS in children in the Khuzestan province, south west Iran, during a 10-year period (2006-2015).Patients and methods: We extracted data retrospectively from acute flaccid paralysis committee from healthcare centers in all cities of the province, over a 10-year period (from January 1, 2006 to December 31, 2015). In this study all children under 15 years of age with Guillain-Barre syndrome were surveyed. In order to compare the frequency of GBS in different seasons and months we used the Chi Square test. Results: From 187 cases of GBS, 101 (54%) were males, 86 (46%) females with sex ratio 1.17:1. The mean age of the children was 5.39 ± 4.02 years. The highest occurrence of GBS was observed in autumn (32.1%) followed by winter (27.3%). The highest number of cases (28; 15%) occurred in December and the lowest (8; 4.3%) in September. There was seasonal (P=0.006) and monthly (P=0.036) variation in occurrence of GBS throughout the year with more prevalence in autumn and September. Conclusion: Our study showed that there is a significant monthly and seasonal variation in children with GBS in Khuzestan province.
