On the reliability assessment of a controlled dyke failure
Authors: de Gast Tom , Hicks Michael A. , van den Eijnden Abraham P. , Vardon Philip J.
Published: July 2020

A reliability-based analysis framework, accounting for uncertainty arising from the spatial variability of soil properties, has been validated for the controlled, well-instrumented slope failure of an historic dyke in the Netherlands. Using soil property statistics derived from the results of laboratory and cone penetration test (CPT) data for the different soil layers at the site, the dyke was analysed for the initial (i.e. operating) conditions, as well as for the later stage of the test leading up to failure. The computed probabilities of failure and back-figured factors of safety were consistent with the point at which failure occurred in the test, as was the range of possible failure mechanisms. The uncertainty in the stability assessment was reduced by considering the spatial nature of the soil variability, and by conditioning analyses to CPT measurement data. It is shown that the reliability-based approach enables more informed stability assessments that could make the difference between a dyke being assessed as safe or requiring costly improvement.

Published: July 2020

В работе разработаны пьезоэлектрические сенсоры на основе полимеров с молекулярными отпечатками для определения карбоновых кислот в газовой фазе. Цель работы состояла в разработке способа пьезосенсорного определения карбоновых кислот в паровоздушной смеси над раствором этилового спирта.Модификацию пьезоэлектрических сенсоров проводили полимерами с молекулярными отпечатками полученными на основе ароматического сополимера 1,2,4,5- бензолтетракарбоновой кислотыс 4,4′-диаминодифенилоксидом. В результате были получены сенсоры с селективными покрытиями:ПМО-Acetic, ПМО-Propionic, ПМО-Butyric. Для всех полученных сенсоров характерны низкие вели-чины относительного стандартного отклонения (не более 6%). При этом предел обнаружения карбоно-вых кислот составил 1.10-7 ммоль/дм3, а диапазон определяемых концентраций 1.10-1-1.10-6 ммоль/дм3.Полученные градуировочные графики имеют линейный вид и коэффициент детерминации более 98%для всех разработанных ПМО-сенсоров.В работе установлено, что модифицированные сенсоры избирательно реагируют только на текарбоновые кислоты, которые были использованы в качестве шаблонов при их синтезе. Это позволило апробировать эти сенсоры при анализе промежуточных фракций этанола: дистиллята, эпюрата, кубовой жидкости и сивушного спирта. Показано, что кубовая жидкость содержит все три карбоновые кислоты в незначительном количестве. В дистилляте и сивушном спирте содержится масляная кислота, при этом наибольшее содержание примесей карбоновых кислот зафиксирована в промежуточной фракции эпюрата.

Исследована экстракция хлоридных комплексов иридия (IV) и родия (III) в двухфазной воднойсистеме (ДВС) без введения дополнительного реагента. Предложена двухфазная водная система (ДВС)полиэтиленгликоль (ПЭГ-1500, ПЭГ-115) – NaCl – (NH4)2SO4 - H2O для избирательного извлеченияиридия (IV) без введения дополнительного реагента. Цель работы – изучение закономерностей меж-фазного распределения хлоридных комплексов иридия (IV) и разработка экстракционного метода от-деления его от родия (III) с применением ДВС. Квантово-химическими расчетами и методом экстрак-ции показано влияние величины заряда на центральном атоме иона разнозарядных хлоридных ком-плексов иридия (IV) и родия (III) на межфазное распределение их в ДВС. Природа водорастворимогоэкстрагента влияет на полноту извлечения аналита из концентрированных сульфатных растворов. Хлоридный комплекс иридия (IV) практически полностью извлекается ПЭГ-1500, ПЭГ-115 на 95 %; этанолом, изопропанолом (ИПС), ацетоном на 23, 11, 15% соответственно. Хлоридный комплекс родия (III) извлекается ПЭГ на 4% и не экстрагируется этанолом, ИПС и ацетоном. Состав экстрагируемого со-единения установлен методом молекулярной абсорбционной спектрофотометрии. В спектре поглоще-ния экстракта иридия (IV) на основе ПЭГ наблюдаются максимумы поглощения при 435 и 495 нм,характерные для комплекса [IrCl6]2-. В спектрах поглощения водной фазы после отделения иридия (IV)наблюдаются полосы поглощения при длинах волн 412 и 518 нм, характерные для комплекса [RhCl6]3-. На основании проведенных исследований разработан экстракционный метод отделения иридия (IV)от родия (III) в виде разнозарядных хлоридных комплексов. Оптимизированы условия разделения иридия (IV) и родия (III) с использованием ПЭГ. Соотношение водной и органической фазы составляет 3 : 1. Максимальное извлечение хлоридного комплекса иридия (IV) и отделения его от родия (III) наблюдается при концентрации C (Cl-)=1.3∙10-2 -0.5 моль/дм3. При разделении иридия (IV) и родия (III) содержание аналитов вводной и органической фазах системы содержание аналитов определяют спектрофотометрическим методом по окраске [IrCl6]2- и [RhCl6]3-. В оптимальных условиях экстракции иридий (IV) отделяется также от рутения (III), железа (III), алюминия (III), никеля (II), меди (II), кобальта (II), магния (II), цинка (II), свинца (II). Фактор разделения Ir (IV) / Rh (III) составляет 456.

Published: July 2020

The article presents a model of interaction between the DOE and the family, based on the inclusion of parents in monitoring the child’s mental development and the formation of interaction strategies by parents that are adequate to the manifestations of the child’s mental activity. The parental diary acts as an instrument for involving parents in cooperation with DOE, which acts as a “negotiation platform” for DOE and the family regarding the development of the child’s creative imagination. Evaluation of the effectiveness of work with parents is carried out by diagnosing the level of creative abilities of preschoolers. The necessity of the transition from work with parents to social partnership with them is shown, the problem of finding and implementing innovative methods of interaction between the Kindergarten and the family, defined by the concepts of “cooperation” and “partnership”, which currently remains relevant in the context of the formation of new types of activities of the child and the creation, is indicated. environmental conditions of his mental development in the family
Issues on the problem of determining priorities and contents of interaction of school and parents in the modern situation and in the general context of education modernization.
Authors:   Kuban State University Krasnodar, Russia, Ignatovich Svetlana S.
Published: July 2020

The article discusses the issues of determining and substantiating the priorities and content of interaction between the school and parents in the modern situation and in the general context of modernization of education. It is shown that the position taken by parents in the process of educating their children is contradictory. There has been an increase in the number of parents who do not connect the prospects of children's education with the fact of a child attending a comprehensive school. The reason for this contradiction is explained, consisting in the fact that for a long time, parents were virtually deprived of the opportunity to influence the education of the child in school. Shown are two options that exist for parents interested in educating their children. The specific question is posed: where should one look for a social order for education? A way out of this situation is presented – a dialogue between the school and parents, and also the reason for the unpreparedness of the school and parents for such a dialogue is shown. The basis of the bilateral dialogue with the school is the lack of subjective position of parents. It can be formed if they are included in the design of new ed-ucational practices. Parenthood should be formed as an influential civic educational in-stitution.

Authors:   Moscow State University of Psychology and Education, Ignatovich Arina V.
Published: July 2020

The article analyzes the concept of «relation» in psychology and in the theory of mediation. The essential aspects of understanding this phenomenon of the problem of relations between people are highlighted. The relation is shown as a subjective connec-tion between an individual and some external object, and this is manifested in his emo-tions, assessments and behavior. It is concluded that, firstly, relations exist as a system of connections, and secondly, this system is always strictly individualized, it cannot exist outside the individual, which makes it similar to the installation. Three main aspects of the relationship are shown – behavioral, emotional, and cognitive (cognitive). Methods of studying the relationship of the subject to the settlement of disputes are highlighted. The survey was conducted on the Facebook social network, as well as in the military unit of Sochi, in MBOU secondary school No. 24 of Krasnodar and MAOU secondary school No. 21 in the urban district of Balashikha, Moscow Region. In total, 350 respondents took part in the survey, including 198 teachers, 77 military, 66 doctors, and representatives of other professions. A sociometric approach to the study of group structure is presented. Attention is paid to interpersonal relations in various social groups: family, student and labor groups, relations between people of different professions, etc.

Authors: Lesnyak Victor , Zhuravleva Veronika , Averyanov Alexandr
Published: July 2020

Backgrounds. Image diagnostics methods have become particularly important during the COVID-19 pandemic, and computed tomography of the thorax (CT) is considered to be the gold standard in the cases of lung lesion and in the evaluation of changes in the pulmonary parenchyma in dynamics.
However, it is well known that the CT method is associated with a significant radiation effect, especially given the fact that repeated, and often reiterated control CT-tests are required for many patients who suffer COVID -19 or have recovered from the disease.
In order to reduce the potential radiation exposure and receive some additional diagnostic information, we applied the magnetic resonance imaging (MRI) method for viral pneumonia in the FMBA of Russia, which was redesigned as a center for the treatment of patients with COVID-19.
A Study on the Largest Hydraulic-Fracturing-Induced Earthquake in Canada: Observations and Static Stress-Drop Estimation
Authors: Wang Bei , Harrington Rebecca M. , Liu Yajing , Kao Honn , Yu Hongyu
Published: July 2020

On 17 August 2015, an Mw 4.6 earthquake occurred northwest of Fort St. John, British Columbia, possibly induced by hydraulic fracturing (HF). We use data from eight broadband seismometers located ∼50  km from the hypocenter to detect and estimate source parameters of more than 300 events proximal to the mainshock. Stress-drop values estimated using seismic moment and corner frequency from single-event spectra and spectral ratios range from ∼1 to 35 MPa, within the typical range of tectonic earthquakes. We observe an ∼5-day delay between the onset of fluid injection and the mainshock, a b-value of 0.78 for the sequence, and a maximum earthquake magnitude larger than the prediction based on the total injection volume, suggesting that the Mw 4.6 sequence occurred on a pre-existing fault and that the maximum magnitude is likely controlled by tectonic conditions. Results presented here show that pre-existing fault structures should be taken into consideration to better estimate seismic hazard associated with HF operations and to develop schemes for risk mitigation in close proximity to HF wells.

Authors: Nasimi Maryam , Daneshpazhooh Maryam , Nikoo Azita , Azizpour Arghavan , Safoura Shakoei
Published: July 2020

Introduction: Multiple osteoma cutis is a rare skin disorder characterized by tiny bone fragments deposition in the skin. It is a benign disease, which occurs as primary or secondary forms. Secondary osteoma cutis most commonly appears on the facial acne scars in middleaged women. The exact etiology of this phenomenon is unknown, but it may be induced by osteoblastic metaplasia of mesenchymal elements.
Case Presentation: Herein, we report a 70-year-old man with a history of multiple basal cell carcinoma (BCC) of the scalp caused by radiotherapy, who referred to our tumor clinic with multiple skin-colored subcutaneous papules and nodules on his scalp from 2 years ago along with cutaneous side effect changes of radiodermatitis. In the histological examination of lesions with differential diagnosis of BCC, cysts, and adnexal tumors, the diagnosis of osteoma cutis was established without any evidence of BCC.
Conclusion: Osteoma cutis is a rare disorder most commonly affecting the face, but our patient had multiple lesions of the scalp. The inflammatory changes of radiodermatitis may be the principal cause of this change.
Intrauterine Contraceptive Device Complication: Migration to the Small Bowl and Ovary Concurrently
Authors: Sasani Mohammad Reza , Soltani Amir Hossein
Published: July 2020

Intrauterine Contraceptive Device (IUD) is a useful and reversible contraceptive method. This method has potential complications. Uterine perforation and IUD migration is rare but is a serious complication. Migrated IUD could situate in different organs such as bowel loop, urinary bladder, fallopian tube, or ovary. However, the presence of a displaced IUD simultaneously in the two organs is a rare event. Ultrasonography is an appropriate and initial method for evaluating the IUD location. Abdominopelvic x-ray, computed tomography, and MRI are adjunctive imaging modalities. We present a case with migrated IUD, which was located in the right ovary and small intestine simultaneously.

Authors: ZHANG Zhiwei , LI Bojun , WANG Zhichao , WU Lina , SONG Lili , YAO Yexiang
Published: July 2020

Background: We aimed to systematically evaluate the efficacy of high-voltage pulsed current (HVPC) in the treatment of pressure ulcer.
Methods: We searched the databases of PubMed, Cochrane Library, Elsevier and EMBASE to identify randomized controlled studies on the application of HVPC in pressure ulcer treatment, up to January 2019. Two authors independently screened the literature according to the inclusion and exclusion criteria, extracted the data and evaluated the quality. RevMan 5.3 software was used for statistical analysis. Four randomized controlled trials involving a total of 176 patients were included in the study.
Results: Meta-analysis showed that the percentage of wound area reduction in the HVPC treatment group was higher than that in the control group (95%CI 24.59, 47.76, P<0.001). Descriptive analysis showed that there was no significant difference in wound healing between the HVPC treatment group and the control group. One study reported that there was contact dermatitis, and the rest of the studies reported no adverse events.
Conclusion: Compared with the conventional therapy, the combination with HVPC therapy can reduce the area of pressure ulcers more effectively. However, due to the small number of the studies included in this evaluation, the conclusions need to be verified by more high-quality studies.

Published: July 2020

Background: Infertility is a public health problem and can lead to depressive symptoms. In recent years, the WHO-five Well-being Index (WHO-5) has been used as a screening measure for depression, but study on psychometric properties in people with infertility is scarce. The objective of this study was to examine the reliability and validity of the Persian version of the WHO-5 in people with infertility.
Methods: Overall, 539 infertile patients from a referral infertility center in Tehran, Iran in the period between May and Aug 2017, completed the WHO-5, along with other psychological measures: the Patient Health Questionnaire-9 (PHQ-9) and the Hospital Anxiety and Depression Scale (HADS). Construct validity and internal consistency of WHO-5 were evaluated using confirmatory factor analysis (CFA) and Cronbach’s alpha, respectively. Convergent validity was examined by relationship with PHQ-9 and HADS.
Results: The prevalence of poor well-being was 44.3% and that of depression was 18.6%. CFA confirmed the unidimensional factor structure of the WHO-5. Internal consistency of the WHO-5 was good (Cronbach’s alpha=0.858). The WHO-5 significantly correlated with the PHQ-9 (r=-0.522), HADS-anxiety (r=-0.524) and HADS-depression (r=-0.630), confirming convergent validity.
Conclusion: The WHO-5 is a short and easy to use questionnaire with satisfactory reliability and validity that appears suitable for use as a screening test for depressive symptom in infertile people. In addition, the prevalence of depression and poor well-being was very high in this population.

Analysis of Crisis Management of Medical Disputes in China and Australia: A Narrative Review Article
Authors: YIN Tianlu , LIU Zhaojie , XU Yanli
Published: July 2020

At present, the increasing trend of medical disputes has become a serious problem in the work of medical institutions, and directly affects the social stability and orderly development of the institutions. We searched the literature on medical disputes and crisis management in China and Australia within PubMed (2010-2019), China Knowledge Network (CNKI, 2010-2019), and Wanfang Data Knowledge Service Platform (2010-2019). There are several drawbacks in the management of hospital medical disputes in China: 1) the knowledge of crisis is unilateral and not systematic; 2) there are too much stereotype thoughts in crisis management; 3) the crisis attribution is too simple; the crisis impact assessment is insufficient. It is worth learning from Australia’s system, including the legal system, relevant non-governmental organizations, and doctor-patient communication. In view of the malpractice existing in China's medical dispute management, Australia's legal system for handling disputes, doctor-patient communication and other aspects are worthy of our reference. In particular, the construction of third-party supervision and mediation institutions and the prevention of doctor-patient disputes should be optimized.
Scorpions and Their Human Mortality Report in Iran: A Review Article
Authors: FIROOZFAR Faranak , SAGHAFIPOUR Abedin , JESRI Nahid
Published: July 2020

Background: The scorpions have enjoyed medical importance from ancient times because of their morphological structure and venom. The identification of the species of these arthropods has been more emphasized than any other aspects. The purpose of this study was to determine scorpion’s fauna and mortality rates of their victims as reported in Iran.
Methods: In this review, published documents during 1966–2018 related to medically important scorpions and mortality reports due to scorpionism were searched in the data bases such as Web of Science, PubMed, Scopus, Google Scholar and etc., using key words including scorpion, species, classification, Iran, family, species, and the names of all 31 provinces of Iran.
Results: Overall, 169 sources were found. Based on the STROBE checklist, the quality of the documents was also considered, and ultimately, 95 sources were selected. Sixty-four species of scorpions have been identified in Iran and 86% of the species belong to the Buthidae family, and the rest (9.5%, 4.5%) belong to the Hemiscorpiidae and Scorpionidae families, respectively. These species live mostly in tropical regions of Iran. The dangerous scorpions and their mortality reports are often recorded from southern regions such as Khuzestan and Hormozgan provinces.
Conclusion: Due to the significant increase in the abundance of scorpions in Iran over the past 30 years, it is expected that this trend will continue by researchers, and the fauna of scorpions is regularly reconsidered.

Methods: A total of 104 patients with SAP (SAP group) and 101 patients with mild acute pancreatitis (MAP) (MAP group) admitted to Affiliated Hospital of Jining Medical University, Jining, China were enrolled. The PCT and CRP in serum were detected by a full-automatic biochemical analyzer, and N% in peripheral blood was measured by a hemocyte analyzer.
Results: The peripheral blood PCT, CRP, and N% in the SAP group were significantly higher than those in the MAP group (P<0.001). Multivariate Logistic regression analysis showed that acute physiology and chronic health evaluation II (APACHE II) score, Ranson score, PCT, CRP, and N% were independent risk factors for SAP. The receiver operating characteristic (ROC) curve showed that the area under curve (AUC) of PCT, CRP, and N% in diagnosing SAP were 0.906, 0.840, and 0.834 respectively, while that of combined detection was 0.972. The AUC of PCT, CRP, and N% in diagnosing SAP death were 0.907, 0.900, and 0.894, respectively.
Conclusions: Peripheral blood PCT, CRP, and N% contribute to the diagnosis and prognosis of SAP.

Published: July 2020

Background: The discourse of HIV and AIDS determinants is dominated and developed by international institutions through WHO, UNICEF, and donor institutions. We aimed to look at the discourse in the HIV and AIDS prevention discourse by the elite. This research was conducted in 2019 in Palu City, Central Sulawesi, Indonesia in Palu City, Central Sulawesi, Indonesia.
Methods: We used qualitative research aiming to obtain a full picture of a matter according to the human perspective studied.
Results: There was a pressure from various groups so that all people who have the potential to increase the HIV and AIDS trends must be dealt with explicitly, even religious leaders urged to immediately close down the main source of the disease, namely prostitution, LGBT activities that are considered very contrary to culture and any religion.
Conclusion: The discourse in the HIV and AIDS prevention discourse in Palu city has not yet occurred in the discourse synergy developed by the elite, even the program policies are domination and hegemony.

Background: The incidence and mortality from prostate cancer in most native Asian populations remain low although a gradual increase is observed over the last years.
Methods: The statistical analysis of official data on prostate cancer mortality and morbidity was performed for the whole country and for Pavlodar Region.
Results: The increase in the incidence of prostate cancer among the population of Kazakhstan is observed, which may be attributed to the introduction of screening program based on serum PSA. Still, the crude incidence rates in Kazakhstan are below world indices. Over the last few years, the decreasing prostate cancer mortality is observed that might be influenced by early diagnosis. The age-standardized incidence rates show that the majority of prostate cancer cases occur in advanced ages (70 years and older).
Conclusion: More research is needed to determine the risk factors for prostate cancer, as well as ethnic and geographical trends for the population of Kazakhstan

Background: Accurate estimation of active general practitioners (GPs) is a concern for health authorities to estimate requirements. This study aimed to accurately estimate GPs active supply in Iran using three sources capture-recapture (CRC) method.
Methods: This cross-sectional study collected data during 2015-2016, targeting all GPs registered in three independent data sources; a national survey from all hospitals, database of human resource management office at health ministry and physicians' offices databank. Variables including medical council codes, GP names, surnames and national ID codes were used for data linkage among the three sources. Three sources CRC method was applied using log-linear models to estimate the total number of active GPs in STATA software.
Results: Overall, 27,048 GPs were identified after removing the duplicate records. Based on CRC three sources data, the total number of GPs were 53,630 in 2015-2016. Distribution of GPs per 1,000 population among the provinces indicates that provinces of Kohgiluyeh & Boyer Ahmad, Mazandaran, Golestan and Yazd with ratios of 1.28, 1.28, 1.21 and 1.17 physicians rank the highest proportion of GPs and the provinces of Sistan & Baluchestan, Ilam, Zanjan, Alborz, North Khorasan with corresponding ratios of 0.24, 0.40, 0.40, 0.43 and 0.45 GPs ranked the lowest.
Conclusion: CRC method is known to be the best and rapidest method to estimate active GP due to its compatibility for the current situation of databanks in Iran. Therefore, this method is a good application in human resource distribution and planning.

Published: July 2020

Background: The goal of this study was to determine hazard rate of death rate and the causes of death in Iranian patients with Traumatic spinal cord injury (TSCI).
Methods: Overall, 1024 patients with chronic traumatic spinal cord injury referred to Brain and Spinal Injury Research Center, Tehran University of Medical Sciences, Tehran, Iran from Jan 2013-2017 were enrolled. Epidemiological and neurological data, along with secondary complications were recorded for all participants. In the case of death, the cause, and the date of death were recorded. The Kaplan–Meier method was used for survival analysis. A log-rank test was carried out to compare survival due to different risk factors. Risk factors and relative risk estimates associated with death were assessed by means of a Cox regression model.
Results: Nineteen percent were lost to follow up. During the follow-up period, 22 out of 830 remaining cases (2.6%) died. Deaths were only observed in patients with cervical injuries (59% in C1-C4 level and 41% in C5- C7 level). Kaplan–Meier Log-rank test showed that probability of survival was significantly less in females, complete injury cases, patients with cervical spine injury, depression, and ADR (Autonomic dysreflexia). Controlling for age, sex and education level, Cox regression model showed that hazard rate of death was significantly affected by the categorical variables such as level of injury (HR=0.2, 95% CI=0.12-0.39), severe ADR.
Conclusion: Probability of survival is lower in female individuals, cases with complete injuries, patients with cervical spine injury, individuals wi-th depression (BDI>10), and clients who experience ADR.

Authors: NEGRICHI Samira , TALEB Salima
Published: July 2020

Background: Chemotherapy may lead to cancer patient malnutrition, associated with reduced response, and increased complications to anticancer therapy. This study aimed to evaluate the nutritional status of Algerian colorectal cancer patients.
Methods: This cross-sectional study was conducted during 2016-2017 at the Oncology departments from the Algerian East included 90 patients with colorectal cancer. For each patient, a questionnaire, anthropometric measurements and biochemical tests have been done.
Results: The 50-59 yr and 60-69 age groups represented more than half of the population. Obesity and underweight were significantly higher in female patients according to their actual Body mass index (BMI). Prevalence of underweight increased after cancer diagnosis, while obesity prevalence has decreased significantly. The malnutrition classification based on Mid-upper-arm muscle circumference (MUAMC) and the triceps skinfold thickness (TST) has shown a significant higher prevalence of malnutrition among male patients than females. The classification of Nutrition risk index (NRI) has shown a significant high percentage of male patients having malnutrition. In our study, no significant differences were recorded for biochemical tests. Anemia recorded the higher prevalences for both sex compared to other deficiency. Hypoironemia prevalence’s was higher among male patients than females while hypokalemia and hypoproteinemia prevalence’s were higher in female patients.
Conclusion: Malnutrition in CRC patients must be combated by early detection to decrease complications associated to cancer and chemotherapy.

Published: July 2020

Background: Tamoxifen (TAM) is widely used for adjuvant therapy in breast cancer patients. Tamoxifen therapy may lead to serious side effects. Anti-apoptotic substances in combination with chemotherapy drugs can result in additive or synergistic effects. Lauryl gallate (LG), a Gallic acid derivative, has been proven to inhibit tumor growth, without affecting normal cells. This study aimed to investigate the synergistic effect of TAM and LG in breast cancer cell line (MCF-7).
Methods: In this experimental study, performed in ShahreKord University of Medical Science, Iran in 2017, the MCF-7 cells were treated by final concentrations of 10 μM TAM alone, and in combination with 200 μM of LG. We also used EX-527, as SIRT-1 inhibitor to examine the role of SIRT1 in cell apoptosis. BCL-2 and SIRT1 gene expression were measured by real-time PCR method, and cell apoptosis was investigated by flow cytometry.
Results: Tamoxifen alone and in combination with LG decreased BCL-2 expression 2.64±0.75 and 6.38±1.9 fold, respectively, after 48 h (P<0.05). SIRT1 expression was increased 1.67±0.22 and 2.47±0.34 - fold by TAM alone and in combination with LG, respectively (P<0.05). TAM alone and in combination with LG increased the percentage of apoptotic cells 15.79±2.81 and 60.67±6.23 percent, respectively after 48 h (P<0.001).
Conclusion: The combination of LG and TAM is more effective for induction of apoptosis of breast cancer cells, compared to individual use of each. Thus, our data pave the way for new therapeutic options for suppressing breast cancer growth.
