Effect of Zeolite and Zinc on the biochemical characteristics of canola upon drought stress

Nasser Shahsavari, Hasnah Mohd. Jais, Amir Hossein Shirani Rad

Sains Malaysiana, 2014;43:1549-1555.

The effects of zeolite and zinc foliar applications on the biochemical characteristics of canola cultivars under different moisture regimes were investigated in a study conducted during the 2010 and 2011 growing seasons. The study was completed using a factorial split-plot experiment based on randomized complete block design (RCBD) with three replications at the Seed and Plant Improvement Institute (SPII), Karaj, Iran. The treatments were: irrigation (I): complete (I1) and restricted (I2); zeolite (Z): 0 (Z1) and 15 ton ha-1 (Z2) and Zn: 0, 0.1 and 0.2% concentrations of zinc sulfate (Zn1, Zn2, and Zn3) at the pod formation stage. These treatments were applied during the pod formation stage to the Licord, RGS003 and Opera cultivars. This study showed that although applying Z and Zn had positive effects on the quality of canola, the highest performance and the best results were obtained using a combination of Z and Zn. The combined application of Z and Zn decreased the proline and carbohydrate contents to 44.35 and 34.42%, respectively. Therefore, with the low cost of natural Z and moderate Zn intake, these treatments can be used to enhance the performance of canola, especially in regions frequently subjected to water stress.

PMID: 23986467 DOI: 10.1177/0309364613498537

BACKGROUND: Rheumatoid arthritis is a chronic inflammatory joint disease which affects the joints and soft tissues of the foot and ankle. Rocker shoes may be prescribed for the symptomatic foot in rheumatoid arthritis; however, there is a limited evidence base to support the use of rocker shoes in these patients.
OBJECTIVES: The aim of this study was to evaluate the effectiveness of heel-to-toe rocker shoes on pain, disability, and activity limitation in patients with rheumatoid arthritis.
STUDY DESIGN: Clinical trial.
METHODS: Seventeen female patients with rheumatoid arthritis of 1 year or more duration, disease activity score of less than 2.6, and foot and ankle pain were recruited. Heel-to-toe rocker shoe was made according to each patient's foot size. All the patients were evaluated immediately, 7 and 30 days after their first visit. Foot Function Index values were recorded at each appointment.
RESULTS: With the use of rocker shoes, Foot Function Index values decreased in all subscales. This reduction was noted in the first visit and was maintained throughout the trials.
CONCLUSION: Rocker shoe can improve pain, disability, and activity limitation in patients with rheumatoid foot pain. All the subjects reported improved comfort levels.
CLINICAL RELEVANCE: The results of this study showed that high-top, heel-to-toe rocker shoe with wide toe box was effective at reducing foot and ankle pain. It was also regarded as comfortable and acceptable footwear by the patients with rheumatoid foot problems.

PMID: 33811803 DOI: 10.1002/nop2.870

AIM: To investigate the effect of self-administration of medication programme on medication adherence in cardiovascular inpatients and nurse's satisfaction.
DESIGN: Randomized clinical trial with parallel-group design guided by the CONSORT checklist.
METHODS: In this study, sixty cardiovascular inpatients were selected through convenience sampling and then randomly assigned to control and intervention groups, in 2018, Iran. The intervention group took responsibility for consuming their prescribed medication according to the self-administration of medication programme and the control group took medications routinely. Medication adherence was measured one and two weeks after the discharge via telephonic follow-up by Morisky Medication Adherence Scale MMAS-8-item and nurses' satisfaction by researcher-made questioner.
RESULT: There was a higher medication adherence level in the intervention group rather than the usual care group at the follow-up. Most nurses in the study environment were very satisfied.
CONCLUSION: The self-administration of medication programme can effectively increase patients' medication adherence and nurses' satisfaction.

Sustainable development inculcates the process of preserving the environment for future generations while maintaining existing human needs. This study attempts to empirically investigate the relationship between CO2 emissions, GDP, energy consumption, and imports and exports using yearly data between 1980 and 2014 for the panel of eight developing countries (i.e., Bangladesh, Egypt, Iran, Indonesia, Malaysia, Nigeria, Pakistan, and Turkey). All the tests for cointegration establish the long-run association among the variables and confirm the environmental Kuznets curve (EKC) hypothesis for the panel of eight countries. GDP and energy consumption remained significant factors for emission intensity both in the long and short run. However, exports found to be positive factor for emissions in the long run only and imports spur emissions in the short run. The country-specific results validate EKC hypothesis for Bangladesh, Iran, Nigeria, Pakistan, and Turkey. The findings are policy oriented and suggest that the countries' economic growth along with energy consumption and exports are highly emission intensive which require necessary adjustments at sustainable development policy front.

Pazooki S, Solhi H, Vishteh HR, Shadnia S, Beigi MJ

Med J Malaysia, 2011 Oct;66(4):342-5.
PMID: 22299554

With the establishment of the inadequate efficiency of atropines and oximes in reducing morbidity and mortality of patients poisoned by organophosphates, more attention is given to using other methods such as Fresh Frozen Plasma (FFP) as a bioscavenger to mop up organophosphate toxins. This randomized clinical trial was conducted on 56 organophosphate poisoned patients who were randomly assigned to the FFP and control groups in order of admission. The routine treatment in both groups included atropine and, in moderate to severe cases of poisoning, pralidoxime. The FFP group received four packs of FFP as stat dose at the beginning of treatment. No significant difference was seen between the two groups on the atropine and pralidoxime dosage, hospitalization length and mortality. The present study showed that using four packs of FFP as stat dose at the onset of treatment had no significant effect on the clinical course of organophosphate poisoned patients.

Khoshbooii R, Hassan SA, Deylami N, Muhamad R, Engku Kamarudin EM, Alareqe NA

Int J Environ Res Public Health, 2021 07 20;18(14).
PMID: 34300161 DOI: 10.3390/ijerph18147711

AIMS: Previous research has shown the efficacy of culturally adapted Cognitive Behavioral Therapy (CA-CBT) in reducing depression, yet its effect on increasing sexual satisfaction is not well documented. In this study, an embedded randomized controlled trial design was used to examine the effect of group and individual CA-CBT on depression and sexual satisfaction among perimenopausal women.
METHOD: A total of 64 depressed Iranian perimenopausal women were randomly assigned to two formats of treatments; sixteen sessions of group CA-CBT and eight sessions of individual CA-CBT, as well as a waitlist control group. Depression and sexual satisfaction were measured using BDI-II and ENRICH, respectively, at T1 (pre-treatment), T2 (post-treatment) and T3 (follow-up).
RESULTS: Repeated measures ANOVA indicated that the women who underwent both group and individual CA-CBT had effectively reduced depression and increased sexual satisfaction between pre-treatment and post-treatment, and it was sustained after six months of follow-ups with large effect sizes of significant differences (p < 0.001), but the control group did not.
CONCLUSION: The results showed promising evidence for the efficacy of both treatment groups of CA-CBT for depression and sexual satisfaction among perimenopausal women. The population mental health burden among perimenopausal women may likely be reduced by propagating this effective treatment.

Malays J Nutr, 2018;24(2):203-213.
MyJurnal

Introduction: Conjugated linoleic acid (CLA) has been studied for its fat mass
reduction effects. This study aimed to determine the effects of CLA supplementation
on body fat mass (BFM) and selected blood lipid profiles among overweight Iranian.

Methods: A total of 180 adults with BMI = 26-29 kg/m2 and BFM exceeding 21%
and 28% for men and women, respectively were recruited through voluntary
participation from weight management clinics in Tehran. They were assigned
randomly to three groups as follows: Group (1) (control group) receives weight loss
diet only; Group (2) receives weight loss diet +3 gr/day CLA supplement (mixture
of cis-9, trans-11 and trans-10, cis-12) twice a day and Group (3) weight loss diet
+3 gr/day CLA supplement as Group (2) twice a day + regular exercise (walking at
5.5-6 km/h for at least 160 minutes/week). The trial was conducted for 12 weeks.
Anthropometric measurements and blood lipid profiles were determined at weeks 0,
6 and 12.

Results: Both Group 2 and Group 3 showed a significant between-group
difference in reduction of BFM (1.3% and 2.6% respectively) compared to Group 1.
Group 2 supplementation showed increased free fatty acid (FFA) (0.44 mM to 0.55
mM) and decreased HDL-chol (47.5 mg/dL to 42.0 mg/dL) between weeks 0 and
12. These results were not observed for Group 3.

Conclusion: Combination of CLA
supplementation with exercise showed BFM reduction in overweight Iranian adults.
Further research is suggested to verify the findings of this study.

Fulltext Effects of family-centered care on the satisfaction of parents of children hospitalized in pediatric wards in a pediatric ward in Chaloos in 2012

Rostami F, Hassan ST, Yaghmai F, Ismaeil SB, Suandi TB

Electron Physician, 2015;7(2):1078-84.
PMID: 26120418 DOI: 10.14661/2015.1078-1084

BACKGROUND: Family-centered care (FCC) involves holistic care and requires cooperation with the family in planning, intervention, and the evolution of the care that is being provided. Many previous studies have provided results that indicate the importance of the family's involvement in pediatric care, but there is still resistance in doing so within the organizational culture of the hospitals in Iran. The aim of this study was to determine the effects of FCC on the satisfaction of parents of children hospitalized in 2012 in the pediatric ward at Razi Hospital in Chaloos, Iran.
METHODS: This Quasi-experimental study was conducted in 2012 in the pediatric ward at Razi Hospital in Chaloos, Iran. Seventy hospitalized children between the ages of 1 and 3 who suffered from diarrhea, vomiting, or pneumonia were selected through convenience sampling. They were divided randomly into two equal groups, a control group (routine care) and an experimental group (family-centered care). SPSS Statistics 14 software was used to analyze the data, and p<0.05 was considered to be significant.
RESULTS: In the FCC group, the mean score of satisfaction among the parents of the children was 20 out of 90 before the intervention, but, after the FCC method was used, it increased to 83.2 out of 90. In addition, a significant difference was found between the scores of satisfaction for the control and experimental groups (p<0.001), and all parents of children in the experimental group expressed high satisfaction.
CONCLUSION: Our findings showed that the practice of FCC in caring for the sick children can increase the satisfaction of their parents significantly. The role of the family's involvement is critical in every component of the intervention efforts, as shown by the constructs of participatory support, educational support, and psychological support. Thus, a notable implication here is that FCC may lead to increased quality of care and should be included in the educational programs of the nursing staff in pediatric ward.

Namazinia M, Mazlum SR, Mohajer S, Lopez V

BMC Complement Med Ther, 2023 Jun 12;23(1):192.
PMID: 37303065 DOI: 10.1186/s12906-023-04028-2

BACKGROUND: Chemotherapy is associated with a wide range of physical and psychological side effects, so complementary and alternative therapies may be practiced as an independent treatment or combined with the standard ones to improve health-related quality of life of cancer patients. Laughter yoga has predominantly been used as a complementary therapy to enhance health and wellbeing of ordinary people and patients with chronic diseases. However, to date, few studies have evaluated the effects of this modern exercise on cancer patients undergoing chemotherapy in clinical settings, to the best of the authors' knowledge. the present study aimed to investigate the effects of Laughter Yoga on the health-related quality of life of cancer patients undergoing chemotherapy.
METHODS: This study was a two-group randomized clinical trial on 69 cancer patients undergoing chemotherapy at Reza Radiotherapy and Oncology Center, Iran in 2018. Patients were randomly divided into intervention and control groups. The intervention group received laughter yoga for four sessions at one-week intervals. Each session consists of one part and lasts for 20-30 min. Patients' health-related quality of life was assessed before and after the laughter yoga sessions using Quality of Life Questionnaire European Organization for Research and Treatment of Cancer (EORTC QLQ-C30) version 3.0. SPSS Statistics (v.20 software was used to conduct Chi-square, independent t-test, Mann-Whitney, Wilcoxon and paired t-tests analyses of the data.
RESULTS: The number of participants in intervention and control groups were 34 and 35, there was no significant difference of demographic and disease related characteristics and pre-intervention HRQOL between two groups. In the intervention group, there is significant difference between pre- and post-intervention scores (Mean ± Standard Deviation) of emotional functioning (12.99 ± 10.49), physical functioning (0.78 ± 6.08), role functioning (3.43 ± 7.97), fatigue (-8.82 ± 22.01), pain (-8.33 ± 11.78), sleep disturbance (-15.68 ± 18.77), and global health and quality of life (6.37 ± 5.04) (p

PMID: 23113160

BACKGROUND: To examine the effects of soy [in the form of textured soy protein (TSP) and soy-nut] on body composition in elderly women with metabolic syndrome (MetS).
METHODS: A 12-week randomized clinical trial was conducted on 75 women between 60-70 years of age with MetS in rural health clinics around Babol, Iran in 2009. The participants were randomly assigned to one of the three groups of soy-nut (35g/d), TSP (35g/d) and control. Body fat, lean mass and anthropometric indicators were measured before and after intervention, too.
RESULTS: Participants were classified as overweight and showing android fat distribution. After 12 weeks of intervention, both soy-nut and TSP groups showed an increase of non-significant in lean mass (0.9 and 0.7 kg), hip circumference (0.45 and 0.28 cm), triceps skinfold (TSF) thickness (0.87 and 0.67mm) and reduction in BMI (-0.15 and -0.33), waist circumference (-0.83 and -1.2) and body fat (-1.5% and -1.7%). Significant increase in the mean change of TSF and lean mass was observed in the users of soy-nut compared to the control group (P<0.01, P<0.05).
CONCLUSION: 12-week intervention of soy had a mild favorable effect on body composition in elderly women with MetS.

Emerging HIV epidemics in Muslim countries: assessment of different cultural responses to harm reduction and implications for HIV control

Todd CS, Nassiramanesh B, Stanekzai MR, Kamarulzaman A

Curr HIV/AIDS Rep, 2007 Dec;4(4):151-7.
PMID: 18366945

Harm reduction, including needle exchange and opioid substitution therapy, has been demonstrated to reduce high-risk behavior and HIV infection among injection drug users. An increasing number of countries in the Middle East, North Africa, and Asia, including those with Muslim majorities, have experienced or are at risk for HIV epidemics initiated by burgeoning injection drug use. Although use of intoxicants is expressly forbidden within Islam, the local culture impacts the interpretation of Islamic law and influences the response to drug misuse, whether punitive or therapeutic. Harm reduction programming has received varying acceptance within this global region, which may be reflected by national trends in HIV prevalence. The purpose of this paper is to examine cultural and religious response to injecting drug use and associated HIV prevalence trends in Malaysia and Iran, with possible application of lessons learned to an emerging situation in Afghanistan.

Abdollahi A, Abu Talib M, Motalebi SA

Iran J Psychiatry Behav Sci, 2015 Dec;9(4):e2268.
PMID: 26834804 DOI: 10.17795/ijpbs-2268

BACKGROUND: Given that happiness is an important construct to enable adolescents to cope better with difficulties and stress of life, it is necessary to advance our knowledge about the possible etiology of happiness in adolescents.
OBJECTIVES:The present study sought to investigate the relationships of emotional intelligence, depressive symptoms, and happiness in a sample of male students in Tehran, Iran.
MATERIALS AND METHODS: This cross-sectional study was conducted on a sample of high school students in Tehran in 2012. The participants comprised of 188 male students (aged 16 to 19 years old) selected by multi-stage cluster sampling method. For gathering the data, the students filled out assessing emotions scale, Beck depression inventory-II, and Oxford happiness inventory. Data analysis was carried out using descriptive and analytical statistics in statistical package for social sciences (SPSS) software.
RESULTS: The findings showed that a significant positive association existed between high ability of emotional intelligence and happiness (P < 0.01). Conversely, the low ability of emotional intelligence was associated with unhappiness (P < 0.01), there was a positive association between non-depression symptoms and happiness (P < 0.05), and severe depressive symptoms were positively associated with unhappiness (P < 0.01). High ability of emotional intelligence (P < 0.01) and non-depression symptoms (P < 0.05) were the strongest predictors of happiness.
CONCLUSIONS: These findings reinforced the importance of emotional intelligence as a facilitating factor for happiness in adolescences. In addition, the findings suggested that depression symptoms may be harmful for happiness in adolescents.

Emotional intelligence as a mediator between rumination and suicidal ideation among depressed inpatients: The moderating role of suicidal history

Abdollahi A, Talib MA

Psychiatry Res, 2015 Aug 30;228(3):591-7.
PMID: 26117250 DOI: 10.1016/j.psychres.2015.05.046

Suicide is a substantial public health problem, and it remains a serious cause of death in the world. Therefore, this study was designed to examine the relationships between brooding, reflection, emotional intelligence (assessed by performance-based test), and suicidal ideation; the mediation role of emotional intelligence on the relationships between brooding and reflection with suicidal ideation; and the moderating role of suicidal history on the relationships between brooding, reflection, and emotional intelligence with suicidal ideation among Iranian depressed adolescents. The study consisted of a cross-sectional sample of 202 depressed adolescent inpatients from five public hospitals in Tehran, Iran completed measures of depression, rumination, emotional intelligence, and suicide attempt history as indices of suicidal ideation. Structural Equation Modelling estimated that depressed adolescent inpatients with high levels of brooding and reflective rumination, and low levels of emotional intelligence were more likely to report suicidal ideation. Moreover, emotional intelligence partially mediated the relationships between brooding and reflective rumination with suicidal ideation. Suicidal history moderated the relationships between brooding, reflection, and emotional intelligence with suicidal ideation. These findings reinforce the importance of emotional intelligence as an influencing factor against the deleterious effects of rumination styles and suicidal ideation. The results indicate that brooding and reflection have detrimental effects on suicidal ideation in depressed inpatients.

Mohammadi G, Sayyah Meli MR, Naderpour M

Med J Malaysia, 2008 Mar;63(1):39-40.
PMID: 18935730

Historically, the recommended treatment for paranasal sinus mucoceles is the complete excision of through an open approach to achieve a cure. Though with the advent of Endoscopic sinus surgery, transnasal Endoscopic sinus surgery has gained more attention in order to manage the sinus mucocele. The aim of this study is to present the efficacy of the Endoscopic marsupialization of sinus mucoceles. From 2001 to 2005, 18 patients with paranasal sinus mucoceles were treated endoscopically. This series includes 6 fronto-ethmoidal, 2 maxillary, 4 ethmoid, 2 sphenoid, and 4 middle turbinate. The presenting signs, symptoms, and radiological findings were reviewed. All patients underwent endoscopic-wide marsupialization of the mucocele; the mean follow up was 13 months. There are 10 male and 8 female subjects who were of an age range of 29-72 years. Patients were treated with endoscopic marsupialization of the mucocele. There were no recurrences in the mean 13-month follow-ups in 17(94%) of patients. Only one patient needed revision endoscopic surgery. Mucocele happens to be the most commonly benign lesion, which causes the paranasal sinus to expand. There is increasing evidence that endoscopic marsupialization of sinus mucocele results in long-term control with very low recurrence rate at or close to 0%. Thus this technique is safe and less invasive than external approaches.

Mirzaei M, Bekri M

Environ Res, 2017 Apr;154:345-351.
PMID: 28161426 DOI: 10.1016/j.envres.2017.01.023

Climate change and global warming as the key human societies' threats are essentially associated with energy consumption and CO2 emissions. A system dynamic model was developed in this study to model the energy consumption and CO2 emission trends for Iran over 2000-2025. Energy policy factors are considered in analyzing the impact of different energy consumption factors on environmental quality. The simulation results show that the total energy consumption is predicted to reach 2150 by 2025, while that value in 2010 is 1910, which increased by 4.3% yearly. Accordingly, the total CO2 emissions in 2025 will reach 985million tonnes, which shows about 5% increase yearly. Furthermore, we constructed policy scenarios based on energy intensity reduction. The analysis show that CO2 emissions will decrease by 12.14% in 2025 compared to 2010 in the scenario of 5% energy intensity reduction, and 17.8% in the 10% energy intensity reduction scenario. The results obtained in this study provide substantial awareness regarding Irans future energy and CO2 emission outlines.

Environmental management of two of the world's most endangered marine and terrestrial predators: Vaquita and cheetah

Lam SS, Chew KW, Show PL, Ma NL, Ok YS, Peng W, et al.

Environ Res, 2020 11;190:109966.
PMID: 32829186 DOI: 10.1016/j.envres.2020.109966

Two of the world most endangered marine and terrestrial species are at the brink of extinction. The vaquita (Phocoena sinus) is the smallest existing cetacean and the population has declined to barely 22 individuals now remaining in Mexico's Gulf of California. With the ongoing decline, it is likely to go extinct within few years. The primary threat to this species has been mortality as a result of by-catch from gillnet fishing as well as environmental toxic chemicals and disturbance. This has called for the need to establish a National Park within the Gulf of California to expand essential habitat and provide the critical ecosystem protection for vaquita to thrive and multiply, given that proper conservation enforcement and management of the park are accomplished. In the terrestrial environment, the cheetah (Acinonyx jubatus) is reduced to a low number worldwide with the Iran subpopulation currently listed as Critically Endangered and the Indian subpopulation already extinct. There is a need for conservation efforts due to habitat loss, but also an indication of the conspicuous threat of illegal trade and trafficking from Africa and Arab countries in the Middle East. Funds have also been set up to provide refuges for the cheetah by working directly with farmers and landowners, which is a critical movement in adaptive management. These are the potential options for the preservation and possibly the expansion of the overall vaquita and cheetah populations.
