The title furan-ocoumarin, C14H12O4 [systematic name: 9-hy-droxy-2-(prop-1-en-2-yl)-2,3-di-hydro-7H-furo[3,2-g]chromen-7-one], crystallizes with two independent mol-ecules (A and B) in the asymmetric unit. The two mol-ecules differ essentially in the orientation of the propenyl group with respect to the mean plane of the furan-ocoumarin moiety; the O-C(H)-C=C torsion angle is 122.2 (7)° in mol-...
BACKGROUND The Avahan Initiative, a large-scale HIV preventive intervention targeted to high-risk populations including female sex workers (FSWs), was initiated in 2003 in six high-prevalence states in India, including Karnataka. This study assessed if intervention exposure was associated with condom use with FSWs' sexual partners, including a dose-response relationship. METHODS Data were fro...
پایان نامه حاضر در مورد امکان سنجی استفاده از مدلسازی آماری مبـتنی برbmd جهت برآورد حجم بحرانی خونریزی درایجاد مقادیر معینی از خطر مرگ ناشی از خونــریزی مــغزی غیرتروماتیک(خود به خودی) می باشد. روشbmd در رابطه با مقدار دوز یا حجم بحرانی یک وضعیت از پیش تعیین شده برای بدست آوردن بهترین پاسخ جهت ارزیابی خطرات سلامتی و بهداشتی و همچنین برآورد مقدار یا حجم بحرانی دوز می باشد. روشbmd یک روش جایگزین...
اسانس گیاه شوید در درمان هیپرلیپیدمی در یک دوره مزمن به بیماران تجویز می شود. در این مطالعه سمیت احتمالی تحت مزمن اسانس این گیاه مورد بررسی قرار گرفت، حال آنکه در مصرف حاد این اسانس سمیتی گزارش نشده است. در این آزمایش 40 رت ماده به 4 گروه 10 تایی تحت گروههای شاهد، a(high dose)، (intermeidate dose)b و (low dose)c تقسیم شد و اسانس بصورت خوراکی تحت دوزهای به ترتیب بالا: بدون اسانس، 2 م...
The current research aims to assess the staff and patients’ effective doses during Nuclear medicine (NM) bone scans procedures. administered activity was utilized quantify doses, while personnel’s were quantified using thermoluminescent detectors (TLD-100). average 650 (440 1440) MBq procedures SPECT gamma camera system. annual dose (mSv) estimated be 2.3 (0.1 4.9). typical patient’s 4.9 (3.6 6...
Background & Objectives: Hepatitis B is one of the major health problems in the world. Health care workers (HCWs) are at high risk of acquiring hepatitis B virus. The aim of this study was to evaluate the prevalence of HBV infection and the immune response to HBV vaccine among the HCWs in Babol, northern...
A hospital trust in the Midlands has said that it is working to understand why some of its staff remain unvaccinated against covid-19 after preliminary findings from a study showed uptake was especially low among doctors and ethnic minority staff. The analysis, published as preprint on 13 February,1 looked at 19 044 University Hospitals Leicester NHS Trust who had all been offered vaccination ...
In the title mol-ecular salt [systematic name: triethylammonium 5-(2,4-dinitrophenyl)-2,6-dioxo-1,2,3,6-tetrahydropyrim-idin-4-olate], C(6)H(16)N(+)·C(10)H(5)N(4)O(7) (-), the cation and anion are linked by an N-H⋯O hydrogen bond. In the crystal, inversion-related barbiturate rings are centrosymmetrically connected through pairs of N-H⋯O hydrogen bonds, forming R(2) (2)(8)R(2) (2)(8) ring motifs.
THE ASYMMETRIC UNIT OF THE TITLE COMPOUND [SYSTEMATIC NAME: 9,10-dimeth-oxy-7-methyl-6,7,7a,8-tetra-hydro-5H-benzo[g][1,3]benzodioxolo[6,5,4-de]quinoline], C(20)H(21)NO(4), contains two independent mol-ecules with very similar bond lengths and angles. The crystal packing exhibits voids of 131 Å(3).
background: the shielding methods in radiotherapy due to delivering an accurate radiation dose to cancer tissues and avoiding unnecessary dose to normal tissues are very important. these methods include lead standard blocks, individual molding and multi leaf collimator (mlc). the mlc method is not still common in iran radiotherapy centers. individual molding is better than the lead block shield...
