Purpose: The aim of this study was to compare higher-order aberrations between personalized TREATMENT (PT) versus personalized TREATMENT advanced (PTA) photorefractive keratectomy (PRK) for myopia and myopic astigmatism.Methods: In this clinical trial, 80 eyes of 40 patients who met inclusion criteria were enrolled. They underwent PRK using PT or PTA algorithm randomly. Higher-order aberrations were measured and compared between the study groups pre-operatively and at months 3 and 6 postoperatively.Results: The two study groups were comparable in terms of preoperative higher-order aberrations.Compared to the preoperative values, higher-order aberrations were significantly increased in the PT group (p<0.001), but decreased in the PTA group (p<0.001). Spherical aberration exhibited a significant increase postoperatively in the PT group (p<0.001) but remained unchanged in the PTA group (P=0.57).Conclusion: PRK using PT algorithm resulted in an increase higher-order aberrations. PTA algorithm provided better results in terms of postoperative higher-order aberrations and could treat pre-existing higher-order aberrations.

To evaluate the effects of different TREATMENTs on seed dormancy breaking of Notobasis, two separate experiments were conducted at Agricultural Sciences and Natural Resources University of Khuzestan, in 2017 with three replications. The first experiment included nine physical, mechanical and chemical TREATMENTs (control, surface scarification, intense scarification, one and two weeks of chilling at 4°C, soaking into hot water for two hours without scarification , soaking in 25°C distilled water for two hours with scarification  and ACID TREATMENT for six and 12 minutes) based on completely randomized designs (CRD). The Second experiment was hormone priming arranged as a factorial experiment based on completely randomized design with gibberellin concentrations (0, 200, 400, 600, 800 and 1000 ppm) and priming duration (12 and 24 hour) as the TREATMENTs. The highest seed germination (40%) obtained from 12 minutes of ACID TREATMENT. Results showed that seed germination reached to 100% after priming seeds with GA3 concentrations for 12 hours. However, increase the priming durations to 24 hours, significantly declined seed germination to 47% in 200 and 400 ppm of GA3 concentrations. The Increase of GA3 concentrations in 12 hours led to a linear reduction of T50 from 31 hours in 200 ppm to 19 hours in 1000 ppm). In 24 hours of priming TREATMENT, T50 followed a Gaussian function and the highest T50 (92 hours) was obtained from 600 ppm. It is recommended to immerse the seeds for 12 minutes in sulfuric ACID and prime with 400 ppm GA3 ACID for 12 hours to break dormancy and increase the vigor index.

People with Parkinson's disease (PD) often have walking difficulty in the advanced stages of the disease and also suffer from balance problems. They perform their functional movements in a smaller range and at a slower rate, which will cause difficulty in performing daily activities. Patients with PD face many difficulties in outdoor activities, community participation, personal tasks, and fine motor skills (e. g. writing). They usually need the help of others. For two decades, a new TREATMENT called Lee Silverman Voice TREATMENT (LSVT) has been used by the speech therapists to treat speech and swallowing disorders in PD patients based on evidence and principles of neuroplasticity. The BIG protocol was added to this method in 2010 (LSVT-BIG). In this method, the whole body is involved and its main focus is on motor skills, which are guided by a physiotherapist and occupational therapist. The main goal of this new method is to improve patient’ s skilled movement in PD, as opposed to the old methods that introduce muscle stiffness as the main problem in these patients. In this method, patients will be required to perform a series of special exercises in sitting and standing positions in a larger range than usual with a specific schedule and in a one-month intensive period. Doing the BIG protocol correctly can make the range of motion softer and larger. The studies also show that the LSVT BIG method is very effective for improving patients' walking patterns and daily activities and significantly increases the quality of life in PD patients. Eventually, the PD patients will be able to perform their motor tasks automatically. Considering the useful results of this method and also the growing trend of its application around the world, it is necessary to enable therapists with this new method and provide more complete services for PD patients.

Introduction: Many efforts have been made to improve Ni-Ti alloy for endodontic use and it has been shown that surface properties and thus cutting efficiency of the rotary files can be improved by processes such as electro-polishing, ion implantation and surface coating. The aim of this study was to evaluate the effect of cryogenic TREATMENT on cutting efficiency of Ni-Ti rotary files.Materials and Methods: In this in vitro study, 60 Ni-Ti rotary instruments (Hero 642, #25, 0.04 taper) were selected and divided into 3 groups of 20. In group I no TREATMENT was used. In group II the instruments were subjected to a deep cryogenic TREATMENT in liquid nitrogen pool (-196oC) for 24 hours and after TREATMENT were immediately tested for cutting efficiency. In group III after cryogenic TREATMENT the temperature of the samples was raised slowly to room temperature for 24 hours. A new piece of test equipment was designed and used. The instruments were attached to the testing machine and rotated in Plexiglas samples for 10 seconds in a working length of 16 mm. The depth of grooves and weight loss of Plexiglas were measured after instrumentation. One-way and two-way ANOVA were used to compare the means of cutting efficacy between the three groups at 95% confidence interval.Results: The instruments which were immediately tested for cutting efficiency had significantly more weight loss and deeper grooves (pweight<0.001; pgroove=0.022), indicating better cutting efficiency. However, there was no significant differences between group I and group III in cutting efficacy (p weight=0.23; p groove=0.61).Conclusion: The results of this study showed that the surface properties of Ni-Ti alloy could be improved by the cryogenic TREATMENT for a limited period of time after TREATMENT, increasing the cutting efficiency of Ni-Ti rotary instruments.

Rosemary plant extract as a natural anti-oxidant is 4 times stronger than synthetic anti-oxidant like BHT and BHA. For this reason, it has been under attention not only for its anti-oxidant properties rather for its anti-inflammatory, anti-tumor, anti-bacterial, and anti-virus properties in different studies. This research investigates the effects of temperature, time, pH, and substance concentration in the labeling of irradiated rosmarinic ACID by radioisotope gallium-67 as a high-resolution imaging agent for SPECT imaging. In this study, gamma irradiated rosmarinic ACID nanoparticles at 20 kGy and 30 kGy levels in two concentrations of 0.5 and 1% were radiolabeled by gallium-67 radioisotope produced in Karaj cyclotron, and their efficiency and radiochemical purity were compared. Labeling conditions (including pH, temperature, time, and compound concentration) were investigated. Quality control was performed by thin-layer chromatography (RTLC). Resulting from the experiments, 30 kGy level and 1% concentration at 45 °C for 30 minutes at pH = 5.5-6 proved to be the best time for labeling rosemary nanoparticles, and the highest radiochemical purity achieved was 95%; radio conjugate also showed good stability after 12 hours.

Background: Hydrofluoric ACID and other fluorine compounds are used in different industries worldwide. Fluoride ion bonding with Calcium and Magnesium ions interferes with cell enzymatic systems and causes cell death. Any hesitation in diagnosis and TREATMENT can lead to irreversible injuries in exposed individuals.Material & Method: This cross - sectional study was conducted on 74 workers who had occupational exposure to Hydrofluoric ACID. After dermal contamination, TREATMENT procedures at the time of exposure and later in the medical center included decontamination with water, topical application of Calcium Gluconate Gel 2.5% and/or Benzalkonium Chloride solution. Workers and physicians were asked to fill in separate questionnaires providing data on the type and extent of burn and TREATMENT procedures. Data were analyzed by descriptive and analytical methods in SPSS data bank.Results: 56 cases (75.7%) had carried out decontamination with water and 24 cases (32.4%) had applied Calcium Gluconate Gel immediately after exposure. In the clinic, TREATMENT procedures included: decontamination for 46 cases (62.16%) and Calcium Gluconate Gel for 70 cases (94.59%). More than 80% of burns were first degree at the time visited by physician and no complications observed in later follow-ups.Conclusion: It can be concluded that the initial washing with water and application of Calcium Gluconate Gel 2.5% at the time of exposure and later in the medical center is an effective and acceptable method in HF burn.

Introduction: Excessive menstrual bleeding is a common complaint and each year around 5% of 30-49 year old women have this problem. The aim of this study is to compare the efficacy and acceptability of mefenamic ACID and tranexamic ACID for treating menorrhea. Attempts have been made to choose a more effective with less complication to treat hyper menorrhea.Materials and Methods: This study is a control trial study and the setting is Shahid Sedugh University, department of obstetrics and gynecology, Yazd in 2001-2005. 75 women with excessive uterine bleeding (hyper menorrhea) were under TREATMENT for five days from day 1 of menses during three consecutive menstrual periods. 36 patients were randomized to take mefenamic ACID 500 mg, Tid; and 39 patients to take 500 mg tranexamic ACID, Qid.Menstrual loss was measured in three control menstrual periods and three menstrual periods during TREATMENT. Duration of bleeding patient's estimated blood loss, sanitary towel usage and unwanted events were also taken into consideration.Results: mefenamic ACID reduced blood loss by 20% and tranexamic ACID reduced blood loss by 50% (P=0.001). Duration of bleeding was not different in patients treated with mefenamic ACID and tranexamic ACID.Conclusions: Tranexamic ACID given during menstruation is a safe and highly effective TREATMENT for excessive bleeding. Patients with dysfunctional uterine bleeding should be offered medical TREATMENT with tranexamic ACID before a decision is made about surgery.

Introduction: Hemophilia is one of the most important coagulation disorders. At the present time the current TREATMENT is factor replacement which may lead to many socio-economic problems and also transmission of some viral infections. In this study we evaluate an alternative TREATMENT to factor replacement to decrease the aforementioned problems. Material and Methods: This was an interventional study and the statistical population included all Hemophilia patients that referred to Besat Hospital. They were randomly divided into two groups: an intervention group of 13 patients and a control group of 15 patients. Tranexamic ACID was only used for the intervention group (15 patients). Then the data was assessed by spss win software. Results: In the intervention group bleeding episodes were reduced significantly (from 4.07 episodes per month to 3 episodes per month) and so was the need for factor replacement (from 80.1 u/kg/m to 58.7 u/kg/m). In the control group bleeding episodes and the need for factor replacement did not differ prior to and during the study. Conclusion: The results of this study showed that daily prophylactic use of TEA is effective in reducing bleeding episodes and decreasing the need for factor replacement in hemophilia patients. However, due to increased PTT and decreased serum clotting factors in patients, the risk of life threatening bleeding is likely to be high. Thus we don’t recommend the use of TEA as a prophylactic measure in hemophilia.  

Background and Objective: Textile wastewaters are known as an important environmental pollutant. The main characteristic of textile wastewater is its colorness, which contains various organic and inorganic pollutants. Therefore it is necessary to treat such effluent effectively before discharging into the environment.Methods: In a fundamental-applicable study, removal efficiency of ACID red 18 and ACID red 14 using zero valent iron powder has been investigated. Parameters studied include pH (3-11), contact time (15-120 min), and initial concentration of iron powder (0.5-2 g/L).Results: Batch experiments show that dye removal was increased with increasing mass of iron powder and contact time, while decreased with increasing of pH. The high removal efficiency was observed in pH=3, contact time=120 min and iron powder concentration of 2 g/L. The result of kinetic studies shows that removal of ACID red 18 and ACID red 14 was best described by pseudo-second order kinetic model.Conclusion: the overall results of present work shows efficient removal of ACID red 18 and ACID 14 by zero valent iron powder.
