Background: Testicular cancer is one of the most common cancers among young men between ages 20-34 in countries with high or very high levels of the Human Development Index (HDI). This study investigated the incidence and mortality of prostate cancer and the relationship with the HDI and its dimensions in Asia in 2012. Materials and Methods: The study was conducted based on data from the world data of cancer and the World Bank (including the HDI and its components). Standardized incidence and mortality rates of testicular cancer were calculated for Asian countries. Correlations between incidence and/ormortality rates, and the HDI and its components were assessed with the use of the correlation test, using SPSS software. Results: There was a total of 14902 incidences and 5832 death were recorded in Asian countries in 2012. Among the Asian countries, the five countries with the highest standardized incidence rates of testicular cancer were Israel, Georgia, Turkey, Lebanon and Kazakhstan and the five countries with the highest standardized mortality rates were Turkey, Georgia, Jordan, Cambodia and the Syrian Arab Republic. A positive correlation of 0.382 was observed between the standardized incidence rates of testicular cancer and the HDI (p=0.009). Also a negative correlation of 0.298 between the standardized mortality rate of testicular cancer and the Human Development Index was noted although this relation was statistically non-significant (p=0.052). Conclusions: There is a positive correlation between HDI and the standardized incidence rate of testicular cancer and negative correlation with standardized mortality rate.

A Case Report of Prolonged Hemorrhage Following Traditional Phlebotomy (Fasd)

Sadeghi Sajjad,Sadeghi Sajjad 대한약침학회 2024 Journal of pharmacopuncture Vol.27 No.1

Phlebotomy, a therapeutic method of bloodletting typically performed using a needle, has a traditional technique known as “Fasd.” In this method, blood is extracted by creating a longitudinal incision on a vein (3-5 mm) with a surgical scalpel blade, usually blade No. 11. Due to the incision in the vessel wall, establishing hemostasis is more challenging compared to conventional methods. Hemostasis is usually achieved within minutes after Fasd. We present a case highlighting an uncommon yet significant complication of traditional phlebotomy. A 55-year-old man with no prior medical conditions underwent traditional phlebotomy at an academic traditional medicine clinic. Senior MD-PhD students in Iranian Traditional Medicine, under professor supervision, performed Fasd. A sterile scalpel blade No. 11 was used to create a longitudinal incision of approximately 4 mm on the patient’s median basilic vein in the right hand. After removing 400 cc of blood, a pressure dressing was applied to the incision site. Despite attempts such as hand elevation, ice pack application, prolonged direct pressure, and tight elastic bandaging, bleeding from the incision persisted. After an hour of supportive therapy, hemostasis was eventually achieved within a few minutes using burnt cotton dressing (a traditional method for blood hemostasis). Following intravenous hydration, the patient was discharged in stable condition and reported no issues during the one-month follow-up. The traditional phlebotomy (Fasd) carries the risk of serious complications, including uncontrolled and prolonged bleeding. Further research on the efficacy and safety of burnt cotton dressing for controlling hemostasis is recommended.

Background With the emergence of the coronavirus disease 2019 (COVID-19) and inability of healthcare systems to control the disease, various therapeutic theories with controversial responses have been proposed. Plasmapheresis was administered as a medication. However, the knowledge of its efficacy and indications is inadequate. This study evaluated the use of plasmapheresis in critically ill patients with cancer. Methods This randomized clinical trial was conducted on 86 patients with malignancies, including a control group (N=41) and an intervention group (N=45) with severe COVID-19 during 2020-21. Both groups were treated with routine medications for COVID-19 management according to national guidelines, and plasmapheresis was applied to the intervention group. C-reactive protein (CRP), D-dimer, ferritin, lactate dehydrogenase, hemoglobin, and white blood cell, polymorphonuclear, lymphocyte, and platelet levels were measured at admission and at the end of plasmapheresis. Other variables included neutrophil recovery, intensive care unit admission, intubation requirements, length of hospital stay, and hospitalization outcomes. Results CRP (P <0.001), D-dimer (P <0.001), ferritin (P =0.039), and hemoglobin (P =0.006) levels were significantly different between the groups after the intervention. Neutrophil recovery was remarkably higher in the case than in the control group (P <0.001). However, plasmapheresis did not affect the length of hospital stay (P=0.076), which could have significantly increased survival rates (P <0.001). Conclusion Based on the study findings, plasmapheresis led to a significant improvement in laboratory markers and survival rate in patients with severe COVID-19. These findings reinforce the value of plasmapheresis in cancer patients as a critical population suffering from neutropenia and insufficient immune responses.

Sadeghi, Hossein,Shourije, Fatemeh Ansar,Masoudi, Masoud The Ecological Society of Korea 2012 Journal of Ecology and Environment Vol.35 No.2

There are different types of compost used as soil conditioners and fertilizers. Plants can have different responses to different forms of compost. This field study was performed to examine the effects of different types of compost on growth factors of three dry rangeland species (Atriplex, $Atriplex$ $lentiformis$; Saltwort, $Seidlitzia$ $rosmarinus$; Haloxylon, $Haloxylon$ $persicum$) and soil properties. The experiment was conducted in the Fars Province of Iran during the year 2010-2011. Compost applications consisted of compost tea, solid compost (SC), solid and liquid mixture (MX) and no compost as the control. The study was a factorial experiment based on a randomized complete block design with 3 replications. The results showed that all the tested compost applications enhanced the growth traits of all three species. It was also demonstrated that the use of compost significantly increased the organic matter (1% probability level [PL]), nitrogen concentration (5% PL), phosphorous (5% PL) and potassium (5% PL) concentrations of the soil. The soil's pH level was unchanged (range, 7.3 to 7.6), and the sodium concentration was also significantly decreased (1% PL) by the use of compost. The higher responses were observed in canopy volume and soil sodium and the lower were observed in stem diameter and soil pH level. Among the three plants in the study, Atriplex showed the best response to the application of compost. Based on the results of this study, it can be recommended that the best compost application to increase growth and improve soil condition is the mixed compost (MX) for Atriplex and the SC for Saltwort and Haloxylon.

Sadeghi, Hossein,Kazemeini, Seyed Abdolreza The Ecological Society of Korea 2012 Journal of Ecology and Environment Vol.35 No.4

In order to investigate the effects of different maize-bean intercropping patterns, and of nitrogen fertilizers on morphological and yield related traits, a factorial study based on Randomized Complete Block Design (RCBD) was performed during the 2010 and 2011 growing seasons in a research filed of Shiraz University, Iran. The first factor of the study was seven different ratios of Maize-Bean intercropping system (Maize sole cropping, Bean sole cropping, and intercropping of maize/bean at the ratios of 1/3, 1/1, 2/3, 3/2 and 3/1) and the second factor was three nitrogen (N) fertilizer application levels (0, 100 and 200 kg N/ha). Results showed that with respect to increasing the levels of N fertilizer, the yield of bean sole cropping decreased but the yield of maize sole cropping increased. On the other hand, in intercropping systems with N fertilizer application, the yield of both crops increased. Results of total land equivalent ratio (LER) for both crops showed that the highest LER value under both 100 and 200 kg N/ha application was that of M1B1 (1 seed of maize after 1 seed of bean, consecutively, on a row with same distance). Under no N fertilizer application the highest LER value was that of M2B3 (2 seeds of maize after 3 seeds of bean, consecutively, on a row with same distance). Overall, it can be concluded that M1B1 is the best intercropping pattern in maize-bean intercropping systems and that the application of N fertilizer can be effective within practical settings of intercropping agriculture, resulting in higher yields.

Oyster Shell Disposal: Potential as a Novel Ecofriendly Antimicrobial Agent for Packaging: a Mini Review

Sadeghi, Kambiz,Park, Kitae,Seo, Jongchul Korea Society of Packaging Science and Technology 2019 한국포장학회지 Vol.25 No.2

The management of oyster shell disposal is an ongoing challenge in the southern coast of Korea because of continuously dumping the oyster shell in environment. Oyster shell wastes could be a biocidal alternative after calcination using a heat treatment. Calcined oyster shell is normally obtained through thermally conversion of $CaCO_3$ (main component in oyster shell (96%)) into CaO. This study provides a brief overview of oyster shell disposal and its potential as an antimicrobial agent with a focus on calcination process, antimicrobial mechanisms, and packaging applications.

Real-Time Implementation of Brain Emotional Learning Developed for Digital Signal Processor-Based Interior Permanent Magnet Synchronous Motor Drive Systems

Sadeghi, Mohamad-Ali,Daryabeigi, Ehsan The Korean Institute of Power Electronics 2014 JOURNAL OF POWER ELECTRONICS Vol.14 No.1

In this study, a brain emotional learning-based intelligent controller (BELBIC) is developed for the speed control of an interior permanent magnet synchronous motor (IPMSM). A novel and simple model of the IPMSM drive structure is established with the intelligent control system, which controls motor speed accurately without the use of any conventional PI controllers and is independent of motor parameters. This study is conducted in both real time and simulation with a new control plant for a laboratory 3 ph, 3.8 Nm IPMSM digital signal processor (DSP)-based drive system. This DSP-based drive system is then compared with conventional BELBIC and an optimized conventional PI controller. Results show that the proposed method performs better than the other controllers and exhibits excellent control characteristics, such as fast response, simple implementation, and robustness with respect to disturbances and manufacturing imperfections.

Monte Carlo calculated TG-60 dosimetry parameters for the β− emitter S153m brachytherapy source : Dosimetry parameters for S153m brachytherapy source

Sadeghi, Mahdi,Taghdiri, Fatemeh,Hamed Hosseini, S.,Tenreiro, Claudio Wiley (John WileySons) 2010 Medical physics Vol.37 No.10

<P>PURPOSE: The formalism recommended by Task Group 60 (TG-60) of the American Association of Physicists in Medicine (AAPM) is applicable for beta sources. Radioactive biocompatible and biodegradable 153Sm glass seed without encapsulation is a beta- emitter radionuclide with a short half-life and delivers a high dose rate to the tumor in the millimeter range. This study presents the results of Monte Carlo calculations of the dosimetric parameters for the 153Sm brachytherapy source. METHODS: Version 5 of the (MCNP) Monte Carlo radiation transport code was used to calculate two-dimensional dose distributions around the source. The dosimetric parameters of AAPM TG-60 recommendations including the reference dose rate, the radial dose function, the anisotropy function, and the one-dimensional anisotropy function were obtained. RESULTS: The dose rate value at the reference point was estimated to be 9.21 +/- 0.6 cGy h(-1) microCi(-1). Due to the low energy beta emitted from 153Sm sources, the dose fall-off profile is sharper than the other beta emitter sources. The calculated dosimetric parameters in this study are compared to several beta and photon emitting seeds. CONCLUSIONS: The results show the advantage of the 153Sm source in comparison with the other sources because of the rapid dose fall-off of beta ray and high dose rate at the short distances of the seed. The results would be helpful in the development of the radioactive implants using 153Sm seeds for the brachytherapy treatment.</P>

Sadeghi, H.,Amrollahi, R.,Zare, M.,Fazelpour, S. Korean Nuclear Society 2020 Nuclear Engineering and Technology Vol.52 No.2

In this study, the neutronic calculation to obtain tritium breeding ratio (TBR) in a deuterium-tritium (D-T) fusion power reactor using Monte Carlo MCNPX is done. In addition, by using COMSOL software, an efficient cooling system is designed. In the proposed design, it is adequate to enrich up to 40% ⁶Li. Total tritium breeding ratio of 1.12 is achieved. The temperature of helium as coolant gas never exceed 687℃. As regards the tolerable temperature of beryllium (650℃), the design of blanket module is done in the way that beryllium temperature never exceed 600℃. The main feature of this design indicates the temperature of helium coolant is higher than other proposed models for blanket module, therefore power of electricity generation will increase.
