The biochemical properties of Rosmarinus officinalis L. affected by irrigation water amount and quality.

Water deficiency, especially in the arid and semi-arid areas, necessitates the proper water use and recycling. The objective was to investigate the effects of deficit irrigation as well as treated wastewater on the biochemical properties of Rosmarinus officinalis L., grown in the arid area of Iranshahr, Iran. A split-split plot design on the basis of a complete randomized block design with three replicates was conducted in 2017. Irrigation water treatments of (I1 = 100% of field capacity, FC), 75% of FC (I2), and 50% of FC (I3) as main plots, reduced (S1), and partial irrigation (S2), as sub-plots, and well water (Q1), treated wastewater (Q2), and the combination of Q1 and Q2 (Q3, 50% + 50%), as sub-sub plots, were tested. Plant biochemical properties including proline (Pr), soluble sugars (SS), and essential oil volume (V) and yield (Y) as well as water use efficiency (WUE) were determined. The I2, treatment, compared with I1, increased Pr, SS, V, Y and WUE by 34.4, 31.9, 52.6, 34.3, and 48.1%, respectively. The S2 treatment also increased plant biochemical properties more than 45% related to S1, and Q2 significantly enhanced the measured parameters compared with Q1 and Q3. Treated wastewater improved the essential oil yield of the plant in water deficit conditions. Accordingly, under deficit water conditions, treatment I2S2, and in the case of unfavorable water sources and deficit water conditions, treatment I2Q2 are recommendable to alleviate water stress and improve the biochemical properties of Rosmarinus officinalis L. in the arid areas.

Comparison of PCR and Conventional Serological Methods for Detection of Brucella spp. in Ovine and Caprine Blood Serum.

Brucellosis is an anthropozoonotic disease. Infection of livestock with Brucella is endemic in most parts of Iran. Sistan-Baluchestan is bordered on the east by the countries of Afghanistan and Pakistan. The high prevalence of brucellosis in livestock in the eastern neighboring countries results in transmission of the disease to this province. The present research aimed to determine the prevalence of brucellosis in small ruminants in the Sistan region of Iran and to compare serological and molecular tests for the detection of brucellosis. Blood samples were taken from 150 randomly selected sheep and goats, and sera were separated. All sera were analyzed by serological (Wright and 2-ME) and molecular (Polymerase Chain Reaction (PCR)) tests. Serological tests were carried out according to the instructions of the Iranian Veterinary Organization The degree of agreement between serological tests and PCR was determined by kappa value. In this study, 17 cases (11.3%) were identified as positive by the PCR method. Wright and 2-ME tests had the highest agreement with PCR in titers ≥2/80 and ≥2/40, respectively. The results of this study show that the brucellosis in sheep and goats has a greater prevalence in the Sistan region than in most other parts of Iran, and this is important in terms of public health. It is suggested that brucellosis vaccination coverage in livestock be increased in this area and that the people in Sistan region must be notified about methods for preventing brucellosis. Also, further studies to compare conventional serologic tests with the gold standard test are recommended.

I-PHAN Study - Use of E-learning modules to Promote Physical activity and wellness among Nurses in order to improve mental and physical health: A research protocol for a randomized controlled trial.

AIM: To develop and test the effectiveness of an E-learning program for promoting physical activity (PA) and wellness among nurses. BACKGROUND: Restrictions during the coronavirus (COVID-19) pandemic drastically changed many people's lives. Maintaining a healthy lifestyle is an everyday challenge faced by the general popula-tion. Nurses are one of the health care professionals who are typically well-educated in taking care of patients. There are studies that show that night shifts, extended shifts, and obesity have a correlation with the prevalence of acute low back pain among female nurses. PA is the key factor in the prevention and treatment of many chronic diseases, resulting in an improvement in the quality of life. The impact of social media and technology on our lives is undeniable in the modern era. DESIGN: This study will be a single-centre, single-blind, randomi-zed controlled trial executed on an E-learning platform to provide the control and intervention groups with a distance learning program. Par-ticipants will be randomly assigned to either the control or intervention group. Participants in the control group will only sign up for module 1 of the PA modules, which only comprises information on PA and health promotion. On the other hand, the participants in the intervention group are expected to carry out 3 modules of exercises at home three days a week for a total duration of 8 weeks. The exercises will be performed at moderate intensity (5-6 on the Borg CR10 Scale). ETHICAL ISSUES: This trial will comply with the declaration of Helsinki 1975, as revised in 2000. Informed written consent will be obtained from the participants. The Sapienza University of Rome, institutional ethics committee and review board approval will be requested for this study. CONCLUSION: Establishing an online PA program with good quality, such as a high level of convenience in access and use, simplified, easy to practice, and made available on social media, can minimize the difficulties faced previously in the implementation of an online PA program for nurses, and may enhance the health and wellbeing of many nurses in healthcare institutions.
