Organ Donation in Islam

Nowadays, the increasing scientific and practical advances in the field of organ donation have caused many discussions in the world. One of these topics is religious beliefs in divine religions, which has always been one of the most important challenges in the field of organ donation. Although there are differences in the views of different religions regarding organ donation, many of these views are close to each other. Often, different sects and religions have accepted organ transplantation with their own conditions. Based on Islamic jurisprudence and Shariah principles, organ donation is permissible under certain conditions; most religious scholars have also accepted this opinion. The Muslim holy book (Qur’an 5:32) has mentioned, “if anyone saved a life, it would be as if he saved the life of the whole people.

Situation of linkage between sexual and reproductive health and HIV-related policies in Islamic Republic of Iran – a rapid assessment in 2011–2

The number of sexual transmission of HIV is increasing globally. Sexual and Reproductive Health (SRH) issues and HIV/AIDS related problems are rooted in common grounds such as poverty, gender inequality, and social exclusion. As a result, international health organizations have suggested the integration of SRH services with HIV/AIDS services as a strategy to control HIV and to improve people’s access to SRH services. The aim of this study was to evaluate the relationship between reproductive health and HIV/AIDS services at policy-making level in Islamic Republic of Iran (IRI). This study was conducted in 2011–2 and was a rapid assessment based on guidelines provided by the World Health Organization (WHO), United Nations Programme on HIV/AIDS (UNAIDS), Family Health International Association, and some other international organizations. In this rapid assessment we used different methods such as a review of literature and documents, visiting and interviewing professionals and experts in family health and HIV/AIDS programs, and experts working in some Non- Governmental Organizations (NGOs). Overall, based on the results obtained in this study, in most cases there was not much linkage between HIV/AIDS policies and SRH policies in Iran. Since integration of HIV/AIDS services and SRH services is recommended as a model and an appropriate response to HIV epidemics worldwide, likewise to control the HIV/AIDS epidemic in Iran it is required to integrate HIV/AIDS and SRH services at all levels, particularly at the policy-making leve

The Effect of Magnetized Saline Water on Yield and Yield Components of Strawberry (Fragaria ananassa cv. Silva)

Introduction Considering the value of water in agriculture and the limitation of this important and vital resource and the existence of intermittent droughts in the country, saving in consumption and optimal use of available water seems necessary. Today, utilizing saltwater is considered one of the practical and effective approaches to minimize water consumption while achieving acceptable economic performance. Given the scarcity of freshwater sources, the utilization of unconventional water for strawberry cultivation holds significant economic importance. Through the application of innovative technologies, such as magnetic technology, the modification of these water sources can lead to increased quantitative and qualitative yields of agricultural products. Salinity stress, which alters the water and nutrient absorption patterns, directly impacts the plant's yield in terms of both quantity and quality. Strawberry is an important commercial product, and the quantitative and qualitative increase of its yield is emphasized from different aspects. The purpose of this research is to the effect of salinity stress under the influence of a magnetic field on the yield and yield components of the strawberry plant. Materials and Methods The purpose of this research was to investigate the effect of salinity stress under the influence of magnetic fields on the yield and yield components of strawberry plants. The factorial experiment was conducted in the form of a randomized complete block design with three replications in 2021 and 2022 in Neka city. The control treatment included full irrigation in all stages of plant growth with normal water (non-magnetic). The treatments include the type of irrigation water at two levels (Non-Magnetic Water (W1) and Magnetic Water (W2)), and water salinity was at three levels (0.86 dS/m (S1), 20 mM sodium chloride (S2), and 40 mM sodium chloride (S3). The strawberry plant of the Silva cultivar was cultivated in 3 x 4-meter plots with a row spacing of 40 cm and a between the spacing of 40 cm. Magnetization of irrigation water was created by passing water through a permanent magnet with a magnetic field intensity of 0.3 Tesla. The salt used for salinity stress was laboratory sodium chloride. The used irrigation method was drip (tape), and the amount of irrigation water and irrigation cycle was done according to the needs of the plant. Soil moisture monitoring was used to calculate the amount of applied water. Results and Discussion The results of analysis of variance showed that the effect of the irrigation water type and different levels of water salinity on the length, diameter, number of fruits per plant, fruit weight, biomass and plant yield was significant at the 1% probability level. The effect of water salinity on the number of fruits per plant was significant at the 1% probability level and on the fruit length and fruit diameter at the 5% probability level. The interaction effect of irrigation water type and water salinity was also significant at the probability level of 1%. On average, during two years of strawberry cultivation with the application of a magnetic field, the length, diameter, number of fruits per plant, fruit weight, biomass, and plant yield were increased by 9.76, 14.14, 23.05, 27.60, 27.08, and 28.36% respectively. The introduction of 20 and 40 mM sodium chloride resulted in a decrease in the physical characteristics of strawberry fruit and overall yield. The most significant reduction was observed in the number of fruits per plant at the salinity level of 40 mM sodium chloride, exhibiting a 56.69% decrease compared to the control treatment. Conclusion The growth of population and expansion of agriculture on one hand and the demand for more harvesting from limited water resources on the other hand, make it necessary to increase water productivity. Lack of water and competition for water resources has caused research to be done in order to reduce water consumption and preserve its resources. Therefore, searching for ways to reduce consumption and preserve water resources is of great importance. One of these methods is using magnetic water. The results of the research showed that the use of magnetic water technology caused a significant increase in the yield and yield components of strawberries compared to the control treatment. In addition, the salinity level of irrigation water had a significant impact on the yield and yield components of strawberries, with the highest yield observed in the treatment without salinity stress when using magnetic water technology. The findings of this study indicate that the application of magnetic water technology can enable the use of low salinity levels and lead to improved strawberry yield

Fuzzy-TOPSIS based Cluster Head selection in mobile sensor networks

One of the critical parameters of Wireless Sensor Networks (WSNs) is node lifetime. There are various methods to increase WSN node lifetime, the clustering technique is being one of them. In clustering, selection of a desired percentage of Cluster Heads (CHs) is performed among the sensor nodes (SNs). Selected CHs are responsible for collecting data from their member nodes, aggregating the data and finally sending it to the sink. In this paper, we propose a Fuzzy-TOPSIS technique, based on multi criteria decision making, to choose CH efficiently and effectively to maximize the WSN lifetime. We will consider several criteria including: residual energy; node energy consumption rate; number of neighbor nodes; average distance between neighboring nodes; and distance from the sink. A threshold based intra-cluster and inter-cluster multi-hop communication mechanism is used to decrease energy consumption. We have also analyzed the impact of node density and different types of mobility strategies in order to investigate impact over WSN lifetime. In order to maximize the load distribution in the WSN, a predictable mobility with octagonal trajectory is proposed. This results in improvement of overall network lifetime and latency. Results shows that the proposed scheme improves the network lifetime by 60%, conserve energy by 80%, a significant reduction of frequent Cluster Head (CH) per round selection by 25% is achieved as compared to the conventional Fuzzy and LEACH protocols

Evaluation of Suitability Groundwater Quality for Agricultural, Drinking and Industrial Purposes (Case Study: South of Chaharmahal and Bakhtiari Province)

The significant reduction of surface water resources and recent recurrent droughts have increased the reliance on groundwater sources, leading to a decline in their quality. In this study, 28 samples of well water from different locations in Khanmirza, Lordegan, Borujen, Ardal and Kiar were collected in 2020-2021 and underwent chemical analysis in the laboratory. To evaluate the quality of the samples for use in agricultural, drinking and industrial sectors, the Wilcox diagram, Schuler diagram and Langlier index were used. Using interpolation methods, the chemical properties of the samples taken within the study area were examined and qualitative zoning maps were prepared using Kriging and inverse distance weighting methods. The results showed that according to the Wilcox diagram, most of the samples are within the range of C2S1 and are suitable for agricultural purposes. According to the Schuler diagram, these samples are within the range of good quality for drinking and based on the Langlier index, they are within the range of precipitating and consumable. This study helps decision-makers to have a clear view and plan comprehensively and effectively for the exploitation and preservation of groundwater resources, taking into account the qualitative maps of groundwater

Background and Objective: One of the important determinants of health in every society is health literacy. The present study was conducted to determine health literacy status of employees of Hamadan University of Medical Sciences and related factors. Materials and Methods: This cross-sectional study was performed in 2016 among 188 employees in Hamadan University of Medical Sciences. The participants were selected through the stratified sampling method. The data collection instrument was Health Literacy for Iranian Adults (HELIA), which was completed through self-report. Data were analyzed using independent t-test, Pearson’s correlation coefficient, one-way ANOVA, and linear regression in SPSS version 22. Results: Most of the participants )74.5%( received health-related information through the Internet. Among the five dimensions of health literacy, the comprehension dimension of health information was more desirable. The highest correlation coefficient between health literacy dimensions was related to the relationship between comprehension and decision-making (r=0.582, P<0.01). On average, health literacy of employees was borderline, and age, marital status, educational status, and sources of information were predictors of health literacy (P<0.05). Conclusion: Overall, the results of the study showed that the average health literacy of employees was borderline. It seems that interventions based on demographic characteristics are required to improve the health literacy status of employees

Phenotypic landscape inference reveals multiple evolutionary paths to C4_4 photosynthesis

C$_4$ photosynthesis has independently evolved from the ancestral C$_3$ pathway in at least 60 plant lineages, but, as with other complex traits, how it evolved is unclear. Here we show that the polyphyletic appearance of C$_4$ photosynthesis is associated with diverse and flexible evolutionary paths that group into four major trajectories. We conducted a meta-analysis of 18 lineages containing species that use C$_3$, C$_4$, or intermediate C$_3$-C$_4$ forms of photosynthesis to parameterise a 16-dimensional phenotypic landscape. We then developed and experimentally verified a novel Bayesian approach based on a hidden Markov model that predicts how the C$_4$ phenotype evolved. The alternative evolutionary histories underlying the appearance of C$_4$ photosynthesis were determined by ancestral lineage and initial phenotypic alterations unrelated to photosynthesis. We conclude that the order of C$_4$ trait acquisition is flexible and driven by non-photosynthetic drivers. This flexibility will have facilitated the convergent evolution of this complex trait

Re-creation of a Key Step in the Evolutionary Switch from C3 to C4 Leaf Anatomy

The C4 photosynthetic pathway accounts for ∼25% of primary productivity on the planet despite being used by only 3% of species. Because C4 plants are higher yielding than C3 plants, efforts are underway to introduce the C4 pathway into the C3 crop rice. This is an ambitious endeavor; however, the C4 pathway evolved from C3 on multiple independent occasions over the last 30 million years, and steps along the trajectory are evident in extant species. One approach toward engineering C4 rice is to recapitulate this trajectory, one of the first steps of which was a change in leaf anatomy. The transition from C3 to so-called “proto-Kranz” anatomy requires an increase in organelle volume in sheath cells surrounding leaf veins. Here we induced chloroplast and mitochondrial development in rice vascular sheath cells through constitutive expression of maize GOLDEN2-LIKE genes. Increased organelle volume was accompanied by the accumulation of photosynthetic enzymes and by increased intercellular connections. This suite of traits reflects that seen in “proto-Kranz” species, and, as such, a key step toward engineering C4 rice has been achieved.Research was funded by a C4 Rice Project grant from The Bill & Melinda Gates Foundation to IRRI (2012–2015; OPPGD1394) and the University of Oxford (2015–2019; OPP1129902)

Engineering chloroplast development in rice through cell‐specific control of endogenous genetic circuits

Summary: The engineering of C4 photosynthetic activity into the C3 plant rice has the potential to nearly double rice yields. To engineer a two‐cell photosynthetic system in rice, the rice bundle sheath (BS) must be rewired to enhance photosynthetic capacity. Here, we show that BS chloroplast biogenesis is enhanced when the transcriptional activator, Oryza sativa Cytokinin GATA transcription factor 1 (OsCGA1), is driven by a vascular specific promoter. Ectopic expression of OsCGA1 resulted in increased BS chloroplast planar area and increased expression of photosynthesis‐associated nuclear genes (PhANG), required for the biogenesis of photosynthetically active chloroplasts in BS cells of rice. A further refinement using a DNAse dead Cas9 (dCas9) activation module driven by the same cell‐type specific promoter, directed enhanced chloroplast development of the BS cells when gRNA sequences were delivered by the dCas9 module to the promoter of the endogenous OsCGA1 gene. Single gRNA expression was sufficient to mediate the transactivation of both the endogenous gene and a transgenic GUS reporter fused with OsCGA1 promoter. Our results illustrate the potential for tissue‐specific dCas9‐activation and the co‐regulation of genes needed for multistep engineering of C4 rice
