    Background: Perineal lacerations resulting from vaginal delivery may cause short and long complications, which lead to some problems in women after the delivery. Ostrich oil is safe for use in skincare and beauty products. The aim of this study was to examine the effect of perineal massage with Ostrich oil on the episiotomy and lacerations in nulliparous women. Materials and Methods: This single‑blind randomized controlled trial was conducted on 77 nulliparous women referred to Razi Hospital in Qazvin (Iran) from May to December 2018. After screening of potential participants, 80 out of 105 pregnant women were selected by convenience sampling and were assigned into the intervention and control groups by block randomization technique. In the intervention group, participants received a perineal massage with Ostrich oil in the active phase and the second stage of labor. The rates of episiotomy and perineal laceration were compared between the two groups. Data were analyzed using Chi-square, t-test and Mann-Whitney. Results: Perineal massage with Ostrich oil in the intervention group significantly decreased the rate of episiotomy compared to the control group (2 = 18.32, df = 1, p < 0.001). However, there was no statistically significant difference in perineal lacerations between the two groups. Conclusions: The results revealed that perineal massage with Ostrich oil could be recommended as an effective, safe, and inexpensive method to improve the rate of episiotomy in vaginal delivery. Perineal massage can be performed by midwives in the first and second stages of labor

    Application of nanofertilizers is one of the promising methods for increasing resources use efficiency and reducing environmental pollutions. Uncontrolled application of chemical fertilizer and pesticides has caused many problems to human health and domestic animals. Nanofertilizers application could be a suitable way to reduce these problems. Accordingly, in order to assess the silicon nanoparticles effect on some vegetative features of basil under salinity stress, a factorial experiment based on a completely randomized design with three replications was conducted in greenhouse condition. Treatments included different levels of silicon fertilizer (without silicon, normal silicon fertilizer and silicon nanoparticles) and salinity stress (1, 3 and 6 ds/m). Physiological traits (chlorophyll and proline content of leaves) and morphological traits (shoot fresh weight and dry weight) were investigated in this study. Results showed a significant reduction in growth and development indices due to the salinity stress.  Leaf dry and fresh weight reduced by increment in NaCl concentration while significantly (<em>P</em><em>≤</em>0.01) increased with silicon nanoparticles application. The chlorophyll content reduced in salinity stress, but increased by silicon nanoparticles treatment. Proline content increased under salinity stress which was a response to stress. Moreover, proline increased by silicon nanoparticles which was due to tolerance induction in plant. Silicon nanoparticles application reduced the pollution effects originated from salinity in Basil

    Trace elements have an important influence on the living system and play a major role in a variety of processes necessary for life. This case study was conducted as an attempt to expand our knowledge of the relationship between trace elements and their effect on acute pancreatitis. Sixty-five patients diagnosed with acute pancreatitis with mean age 43.6 years, along with sixty-five healthy volunteers with a mean age 45.7 years, were included in this study. The obtained results indicated a significant increase in the Cu, Ni and Cr levels, and a significant decrease in the Zn, Mg and Fe levels for acute pancreatitis patients compared with the control group (p &lt;0.001). In addition, a remarkable increase in the Cu/Zn ratio was observed in patients. The current work provides important evidence of correlation between changes in copper and zinc levels and the risk of acute pancreatitis. Also, an increased Cu/Zn ratio may be a useful indication for the diagnosis and monitoring of acute pancreatitis. Moreover, the current study concluded that there is a possible relationship of Mg, Fe, Ni and Cr with acute pancreatitis. Thus, it can be suggested that these elements are reliable to provide indications for warning of the risk of acute pancreatiti
