The effect of maternal organic manganese supplementation on performance, immunological status, blood biochemical and antioxidant status of Afshari ewes and their newborn lambs in transition period.

It has been documented that adequate maternal manganese (Mn) status is vital for performance and health of ewes and their newborn lambs. However, required level and form of dietary Mn in ruminants are not well defined. The current study was conducted to evaluate the effect of maternal organic Mn supplementation on performance, immunological status, blood biochemical and antioxidant status of Afshari ewes and their newborn lambs in transition period. For this purpose, various organic Mn concentrations were utilized as a supplementary ingredient in formulating the diets of ewes. The ewes were randomly allocated into three groups, fed with 0, and 80 mg/kg organic Mn supplemented diet. At the end of the experiment, the parameters including the performance of newborn lambs, as well as biochemical factors, immune status and antioxidant status in ewes and their newborn lambs were evaluated. The results showed a significant increase in the plasma concentrations of Mn, glucose, insulin, thyroid hormones (T3 , T4 ) and enzymatic antioxidants (SOD, GPX , CAT) in ewes and their newborn lambs that were treated with maternal organic Mn. Moreover, inorganic Mn treatments, the concentration of IgG in newborn lamb's plasma, and colostrum of ewes increased. According to this research, organic Mn acts as a valuable and safe supplementary material that could be exploited for enhancing health of ewes and their newborn lambs.

Antioxidant Compounds in the Treatment of Alzheimer's Disease: Natural, Hybrid, and Synthetic Products.

Alzheimer's disease (AD) which is associated with cognitive dysfunction and memory lapse has become a health concern. Various targets and pathways have been involved in AD's progress, such as deficit of acetylcholine (ACh), oxidative stress, inflammation, ß-amyloid (Aß) deposits, and biometal dyshomeostasis. Multiple pieces of evidence indicate that stress oxidative participation in an early stage of AD and the generated ROS could enable neurodegenerative disease leading to neuronal cell death. Hence, antioxidant therapies are applied in treating AD as a beneficial strategy. This review refers to the development and use of antioxidant compounds based on natural products, hybrid designs, and synthetic compounds. The results of using these antioxidant compounds were discussed with the given examples, and future directions for the development of antioxidants were evaluated.

Egg yolk plasma enriched with ß-carotene through the diet of laying hens and adding it to the extender improves the quality of frozen semen in Arabic stallions.

Equine semen cryopreservation is one of the major procedures for the genetic conservation of rare and endangered genotypes. The current study was conducted to evaluate the effect of egg yolk plasma (EYP) enriched with ß-carotene as an antioxidant supplement on INRA-96 extender regarding freezing Arabic stallion sperm. For this purpose, ß-carotene various concentrations were utilized as a supplementary ingredient in formulating the diets of laying hens. Birds were randomly divided into four groups, fed with 0 (control), 500, 1000 and 2000 mg/kg in a supplemented diet with ß-carotene. Subsequently, various variants of enriched extender (INRA-96 + 2.5% glycerol [G]) were gained by adding 2% EYP from four treatment groups. The sperm characteristics, including motility, viability, morphology, plasma membrane integrity (HOS test), lipid peroxidation (MDA) and DNA fragmentation, were evaluated after thawing. According to the results obtained in this study, the addition of EYP from T2 and T4 (500 and 2000 mg/kg of ß-carotene in hens' diet) to the extender (INRA-96 + 2.5% G) leads to an increase in total motility (50.50% and 49.49%, respectively), progressive motility (32.6% and 31.8%, respectively), viability (68.7% and 66.1%, respectively) and plasma membrane integrity (57.7% and 50.6%, respectively). Moreover, lipid peroxidation (1.3 and 1.4 nmol/mL, respectively) and DNA fragmentation (8.6% and 9.9%, respectively) were diminished using the mentioned treatments. However, sperm morphology was not affected by the treatments. In the current study, we concluded that the optimal concentration of ß-carotene in the laying hen's diet (500 mg/kg) could reveal the best results about sperm quality. So, EYP enriched with ß-carotene acts as a valuable natural and safe supplementary material that could be exploited for enhancing stallion sperm quality in cryopreservation conditions.

Milk Supplemented with Organic Iron Improves Performance, Blood Hematology, Iron Metabolism Parameters, Biochemical and Immunological Parameters in Suckling Dalagh Lambs.

This study was conducted to investigate the effect of milk supplemented with organic iron on performance, blood hematology, iron metabolism parameters, biochemical and immunological parameters in suckling lambs. Thirty-six newborn Dalagh lambs were randomly divided into three groups with 12 replications. The control group was fed with milk without organic iron. The other two groups were fed milk supplemented with 25 and 50 mg/d organic iron, respectively. During the experiment, increased daily weight gain and total body weight were observed in the iron-supplemented groups. An increase in the levels of red blood cell, hemoglobin, hematocrit, mean corpuscular hemoglobin, and mean corpuscular concentration in iron supplemented groups was indicated. Consumption of organic iron caused a significant decrease in plasma copper concentration. Total antioxidant status level was lower, but levels of glutathione peroxidase, superoxide dismutase, and catalase were higher in iron supplemented groups. In organic iron supplemented groups, insulin and thyroid hormones levels were significantly increased, and glucose level was significantly decreased. In organic iron supplemented groups, alkaline phosphatase level significantly increased, and aminotransferase level significantly decreased. Overall, the use of organic iron in the milk improved the performance and health in suckling lambs, and since a lower level of supplementation is naturally preferable, supplementation of milk with 25 mg/d organic iron is recommended.

The Effect of Perianal Tramadol Infiltration on Postoperative Pain Following Hemorrhoidectomy.

INTRODUCTION: The present study was attempted to evaluate the effect of perianal infiltration of tramadol on postoperative pain in patients undergoing hemorrhoidectomy. METHOD: This double-blind clinical trial study was carried out on 90 patients with grade 3 and 4 hemorrhoids undergoing hemorrhoidectomy. Patients were randomly assigned into 3 groups of control or bupivacaine or tramadol. Before the surgery, perianal infiltration of .25% bupivacaine or tramadol or normal saline was prescribed to each group, respectively. Data on pain severity (based on the visual analog scale (VAS), the duration of surgery, sedation score, pain at the first defecation, first request time for additional analgesia, nausea and vomiting, and analgesic intakes) were evaluated and analyzed. RESULTS: Duration of surgery was almost similar in all 3 groups (P = .974). The results showed a significant difference in pain score between 3 groups (P ≤.05) at all times after the surgery. In addition, the means of sedation scores (P = .03), pain score at the first defecation (P = .001), the time to first analgesic request (P = .001), and ketorolac administration times (P = .01) were significantly different between 3 groups. Finally, no complication was reported regarding postoperative nausea and vomiting. CONCLUSION: Given the notable efficacy of tramadol in reducing pain after hemorrhoidectomy and its minor side effects, this medication is suggested as an effective topical anesthetic to decrease pain after hemorrhoidectomy.

Monotheistic and spiritual style literature in traditional medicine's resources.

The basis for success of Iranian Gnostics, poets and scientists were moral teaching, attention to origin and searching for specific goals in creation of human and creatures as well as finding some of his essence in studying all phenomena regarding the creation of universe by divine attitude. There is no surprise that such relationship was bilateral and according to his promise to those who truly follow him such that he will show the right path of learning to human in order to obtain the secrets of life. This relationship has resulted in growth of famous Iranian scientists such as Rhazes, Ahvazi, Avicenna, Ferdousi and… at the beginning of the second millennium. Thus, goal of this research is to study the style of writing in original resources of traditional medicine. In order to increase the accuracy of this study, an electronic database version of traditional medicine resources has been prepared. Writing style of Alhavi book (by Rhazes), Kamel-al-Sanaah (by Ahvazi), Canon of Medicine (by Avicenna) and Zakhireye Khwarazmshahi (by Jorjani) was considered. This task was accomplished by searching using related key words such as God, creator, magnificent, omnipotent, transcendent, omniscient and many other similar words and then encoding them. Finally, content analysis of these words was performed. Hundreds of monotheistic words and many small and great texts related to monotheistic literature have been encountered in the literature, and some are mentioned in the following. Rhazes has started some parts of Alhavi by remembering the name of merciful God and saluting his prophets and has mentioned "God" for more than 570 times and the word "God willing" for more than 215 times. Ahvazi has written his book called Kamel-al-Sanaah by using monotheistic literature, so that both volumes of book are started by remembering the name of God and saluting his prophets. In the introduction of first volume of his book, he has acknowledged God due to conferring logic and wisdom to human and has used the word "God" more than 230 times in his book. He has also referred to a famous testimony of Hippocrates and added some more issues in relation to medical ethics. Avicenna has started the Canon of Medicine in five volumes by remembering God and saluting his prophets. When referring to points related to having specific goal in structure of body organs, he immediately has praised God. Jorjani also has followed up the same attitude of three mentioned writers. We have found out that any of the Iranian poets, Gnostics and scientists who have studied nature have reached to the same conclusion from their own point of view, meaning, they all have observed permanent emergence of God in all phenomena of universe. Poets considered the beauties of nature, Gnostics studied mental issues and scientists of natural sciences explored the physiology and anatomy of human body; however, all of them referred to beauty, magnificent, discipline and having goal in creation of universe and all of its phenomena in their books. They have written their valuable books by benefiting monotheistic literature and have published their research results by inference of seeking God and paved the way for next generations. They experienced the usefulness of cumulative effects of spirituality, religion and health on performance and thereby emphasizing the need to incorporate spirituality and religion in teachings curriculums.

The religious and social principles of patients' rights in holy books (Avesta, Torah, Bible, and Quran) and in traditional medicine.

Health protection and promotion in healthy people and restoring patients' health have been the most important themes in medicine and health throughout our history. Therefore, discussion of different aspects of patients' rights includes implementation of these objectives by the medical community, including physicians, nurses, pharmacists, etc., and the people in charge of health affairs. The principal objective of our research is the study of medical ideology and the approaches of our ancestors in relation to different aspects of patients' rights. To study the different ideologies of traditional medicine in relation to patients' rights, appropriate data were extracted from the original resources of traditional medicine and from religious books. By means of library research we studied these resources in addition to electronic versions of the Alhavi book (by Rhazes), the Kamel-al-Sanaah (by Ahvazi), the Canon of Medicine (by Avicenna), the Zakhireye Khawrazmshahi (by Jorjani), the Avesta, the Torah, the Bible, the Quran, and many other resources, and, finally, after searching, gathering, and encoding the findings, analyzed them qualitatively for thematic content. The holy Avesta book clearly insists on the competence of physicians and setting the appointment fee in accordance with peoples' income. The Old Testament (holy Torah) warned government officials who did not observe patients' rights. In the four gospels (holy Bible) the importance of treatment and taking care of the patient is stressed. After the emergence of Islam, medical students, before beginning the principal courses, had to study Islamic jurisprudence, ethics, logic sciences, natural sciences, geometry, astrology, calculus, and similar courses so that after purifying their soul they could enter the saintly profession of physicians. The holy Quran refers to saving the life of a human irrespective of social class, race, and religion, and insists on exemption of patients from physical activity, including the physical aspects of prayer. In these resources, some warnings are offered in relation to fake drugs, the lack of awareness of some physicians, the need for complete preparedness of medical society, and the need to manufacture appropriate drugs and offer a suitable medical service. This information is to familiarize medical and health authorities and persons receiving health services. According to the evidence available about traditional medicine, there was no specific difference between public and professional ethics, public and professional rights, or rights and ethics-ethics were no different from rights nor rights from ethics. So ethics are similar to the soul in the body of rights, and rights are similar to the litter of ethics, and they have developed in parallel with each other. Traditional medicine is community-based and preservation of the health of healthy people is given priority over the treatment of patients; there is insistence that "health rights" has wider scope than "patients' rights". It can be stated that health rights in Iran both before and after the emergence of Islam have been based on guidance from divine religions, observation of humanist ethics, passing suitable courses in the basic sciences, and an introduction to the practical piety of our ancestors, in addition to the syllabus of medical and health education.

The socio-political situation of Avicenna's time and his spiritual messages: on the occasion of 1031 st birth anniversary of Avicenna (23 August 980).

In the fourth century A.H. (tenth century AD) many thinkers, philosophers, jurisprudents, poets, and authors were present in different scientific, literary and health fields in ancient Iran and Islamic world that by their hard attempts the sciences and literature were safe from incidents and resulted in growth, development and innovation of Islamic sciences. Meanwhile, Avicenna was superior to all others and the most famous scientist. He was a great human that by attempting hard, perseverance, stability, patience, and believing in God could complete supreme scientific ranks and compiled encyclopedia of Canon of Medicine and besides gathering many written important issues that most of them were confiscated at libraries of kings. He added medical experiences of ancient Iran and especially Jondishapour University and also his personal experiences and finally Canon of Medicine by benefiting from monotheistic style and science based on faith was written. He has written a book that is regarded as root and basics of modern medicine and by completing it some infrastructure health viewpoints and common medicine were created. It is a kind of book that in spite of scientific advances and production of modern research tools many of its contents are replaced with modern methods of medicine and health, but still many of its health basic messages, research orientation and monotheism with great dynamic mode is considerable at world's medical references. The aim of this study is evaluate the political situation of Avicenna's time and a review of his Godly writings. This is a library study by using electronic version of Canon of Medicine and other related resources. Findings, include writing style of monotheistic literature, and freeing from nihilism and affiliating diseases to Satan, jinn and such issues. It is necessary that our students within course of Iranian and Islamic culture and civilization to be more familiar with monotheistic thoughts and activities of scientists like Avicenna.

Long-term self-renewable feeder-free human induced pluripotent stem cell-derived neural progenitors.

Human induced pluripotent stem cells (hiPSCs) have led to an important revolution in stem cell research and regenerative medicine. To create patient-specific neural progenitors (NPs), we have established a homogenous, expandable, and self-renewable population of multipotent NPs from hiPSCs, using an adherent system and defined medium supplemented with a combination of factors. The established hiPSC-NPs highly expressed Nestin and Sox1. These NPs were continuously propagated for ~1 year without losing their potential to generate astrocytes, oligodendrocytes, and functional neurons and maintained a stable chromosome number. Voltage clamp analysis revealed outward potassium currents in hiPSC-NPs. The self-renewal characteristic of the NPs was demonstrated by a symmetrical mode of Nestin-positive cell division. Additionally, these hiPSC-NPs can be easily frozen and thawed in the presence of Rho-associated kinase (ROCK) inhibitor without losing their proliferation, karyotype stability, and developmental potential. The characteristics of our generated hiPSC-NPs provide the opportunity to use patient-specific or ready-to-use hiPSC-NPs in future biomedical applications.
