Organ transplantation: contemporary Sunni Muslim legal and ethical perspectives

The problems that organ transplantation poses to the Muslim mind may be summarized as follows: firstly, a Muslim believes that whatever he owns or possesses has been given to him as an amanah (trust) from Allah. Would it not be a breach of trust to give consent for the removal of parts of one's body, while still alive, for transplantation to benefit one's child, sibling or parent? Secondly, the Shari'ah (Islamic Law) emphasizes the sacredness of the human body. Would it not then be an act of aggression against the human body, tantamount to its mutilation, if organs were to be removed after death for the purpose of transplantation? In this paper I attempt to illustrate how the Muslim jurists have tried to resolve the dilemma of Muslims by providing them with certain guidelines based on the original sources of Islam, namely, the Qur'an and the Prophetic tradition. In order to assist the followers of other religious traditions to grasp the gravity of the problem posed by organ transplantation to the Muslim mind, I begin by discussing the opinions of Muslim jurists on the issue of utilization of human parts. Thereafter, I touch upon the resolutions taken by the various Islamic Juridical Academies on the issue in question. Finally, I shed light upon the inclusion of organ donation in a Muslim Will and the enforceable nature of such a will.     

Phaseolus lunatus,a New Host of Xanthomonas axonopodis pv. phaseoli in Iran

Common bacterial blight caused by Xanthomonas axonopodis pv. phaseoli (Xap) is one of the most destructive diseases limiting the production of common bean (Phaseolus vulgaris) in Iran. The disease has previously been described on common bean and mung bean from several regions of Iran, including the central plain and south‐western provinces. In this study, lima bean (Phaseolus lunatus cv. Christmas) plants are being reported as a new natural host of Xap in East Azerbaijan and West Azerbaijan Provinces, northwestern Iran. Disease symptoms consisted initially of water‐soaked spots that progressed to irregular necrotic lesions with chlorotic margins. Infection was observed to affect up to 40% of plants in the field. Identification of the pathogen was based on the biochemical and molecular characteristics, as well as the pathogenicity tests. To our knowledge, this is the first report of X. axonopodis pv. phaseoli causing common bacterial blight on lima bean plants in Iran.     

Potassium permanganate–glutaraldehyde chemiluminescence system catalyzed by gold nanoprisms toward selective determination of fluoride

Gold and silver nanoparticles (NPs) are shown to exert a positive effect on the chemiluminescence (CL) reaction of permanganate aldehydes. Interestingly, between various shapes examined, Au nanoprisms have the highest beneficial effect. This effect is even more notable in the presence of sodium dodecyl sulfate (SDS) surfactant. UV‐vis spectra and transmission electron microscopy were used to characterize the NP shapes and sizes. Furthermore, it was observed that iron(III) ions can slightly increase CL emission of this system. This intensification is very effective in the presence of fluoride ions (F^–). These observations form the basis of the method for the high sensitive determination of F^– in the 6–1200 nmol L^–1 concentration range, with a detection limit of 2.1 nmol L^–1. The proposed method has good precision and was satisfactorily used in the selective determination of low concentrations of fluoride ion in real samples. Copyright © 2015 John Wiley & Sons, Ltd.     

Synthesis,radiofluorination, and hypoxia-selective studies of FRAZ: A configurational and positional analogue of the clinical hypoxia marker, [18F]-FAZA

The current work evaluates 1-α-d-(2-deoxy-2-fluororibofuranosyl)-2-nitroimidazole (FRAZ), a novel azomycin nucleoside that is a potential radiosensitizer of tumor hypoxia. FRAZ is a ribose analogue of 1-α-d-(2-deoxy-2-fluoroarabinofuranosyl)-2-nitroimidazole ([¹⁸F]-FAZA), a clinically used hypoxia marker. Preliminary assessment of the cytotoxicity and hypoxia-specific in vitro binding in HCT-110 colorectal cancer cells indicate that the radiosensitization properties of FRAZ are similar to that of FAZA, with a sensitizer enhancement ratio (SER) of ～1.8. An automated radiosynthesis of [¹⁸F]-FRAZ using a commercial automated synthesis unit (ASU) was established (synthesis time ～32 min; radiochemical yield (decay uncorrecetd) ～22%) to facilitate its application in PET-based diagnosis of hypoxic tumors.     

Ethnic elders.

The numbers of elderly people from ethnic groups within Britain is rising rapidly as postwar immigrants age. Ethnic elders face problems owing to age-associated increased risks of common chronic diseases, racial discrimination, and poor access to many health services and social services. This disadvantage will be alleviated through increased understanding of health beliefs held by ethnic elders and ensuring better access to services through mechanisms such as employment of more staff from ethnic minority groups in senior positions, better training of staff, and more appropriate and sensitive environments. The myths that family care is sufficient, that no use of services implies no need, and that assimilation into the majority population will occur must be discounted.

Sedimentary facies and paleoenvironmental interpretation of the Oligocene larger-benthic-foraminifera-dominated Qom Formation in the northeastern margin of the Tethyan Seaway

The well-exposed outcrops of the Bujan, northern Abadeh, and Varkan stratigraphic sections of the Qom Formation in the Iranian part of the “northeastern margin” of the Tethyan Seaway were characterized by abundant biogenic components dominated by foraminifers, coralline red algae, and corals. The Qom Formation is Rupelian–Chattian in age in the study areas. Based on the field investigations, depositional textures, and dominant biogenic components, fifteen (carbonate and terrigenous) facies were identified. These facies can be grouped into four depositional environments: open marine, open lagoon, restricted lagoon, and continental braided streams. The marine facies were deposited on a ramp-type platform. The euphotic inner ramp was characterized mainly by imperforate foraminifera, with co-occurrence of some perforate taxa. These facies passed basinward into a mesophotic (middle) ramp with Neorotalia packstone (F5), coral, coralline algae, perforate foraminiferal packstone (F4), and coral patch reefs (F7). The deeper, oligophotic ramp facies were marly packstones with planktonic and hyaline benthic foraminifera, including large lepidocyclinids and nummulitids. The abundance of perforate foraminifera and the absence of facies indicating restricted lagoonal or intertidal settings suggest that the Varkan section was deposited mainly in open marine settings with normal salinity. The prevalence of larger benthic foraminiferal and red algal assemblages, together with the coral facies, indicates that carbonate production took place in tropical–subtropical waters.
