Introduction: Prostate cancer is one of the most common cancers in men and the fourth common cancer in Iran. Prostate specific antigen (PSA) is the most useful tumor indicator for diagnosing premature Prostate cancer. The specificity and sensitivity of this test increases significantly when we measure the amount of serum free PSA and calculate the PERCENTage.    Materials and Methods: This is a descriptive – analytical study that was done on 125 patients who were under prostatectomy. The patients were divided into 4 groups of <60, 60-69, 70-79 and 80 years old or above In terms of their total PSA (tPSA), the patients were divided to 3 groups of normal (0-3.9 ng/ml), borderline (4-9.9 ng/ml) and increased (10-19.9 ng/ml and 20 or more). As for their PERCENTage of free PSA (fPSA%), they were divided to 3 groups of less than 18%, 18% -25% and more than 25%. Considering the biopsy results, they made 2 groups of BPH and cancer. After that, the tPSA and fPSA% were compared for diagnosing prostate cancer using statistical particularity and sensitivity tests.Results: The finding of the study indicate that by increasing the cut-off values of fPSA% up to 25%, the probability of being afflicted by cancer decreased, especially within the limit of tPSA of 4-9.9ng/ml by which 18.2% of cases were diagnosed as BPH, but there was no indication of cancer (P=0.0001). According to the results of our study, the tPSA within 4-9.9ng/ml was a good indicator for recognizing 7.1% cases of cancer. The rate of its sensitivity and specificity in diagnosing cancer was 20% and 77.39%, respectively.  However, in combination with fPSA% cut-off 18-25%, the rate of sensitivity increased to 53.57% , and that of specificity to 86.6% (0.001).Conclusion: In our study, fPSA%, in combination with tPSA, was able to increase the specificity and sensitivity of the tPSA test. Especially with fPSA% cut-off 18-25% in tPSA within the borderline limit of 4-9.9 ng/ml, which was the purpose of our study, it was able to diagnose cancer to a maximum degree in addition to increasing the sensitivity and specificity. Therefore, we suggest that fPSA% be used  as an aid test to tPSA, especially when the tPSA falls within low or borderline ranges which may be the an indication of cancer in early stages. So, it would increase the diagnostic accuracy of prostate cancer and decrease the costs involved.

Twenty-five soybean cultivars from different maturity groups were evaluated in artificial INFECTION conditions with two isolates of Tiallosporella phaseolina, in a factorial experiment on the basis of RCBD with two replications in greenhouse, to determine their reactions to the above pathogenic fungus. In order to establish INFECTION in soybean cultivars, autoclaved soil (10 min, 121) was contaminated with inoculums propagated on 50 ml corn meal and sand medium in a 250ml flask. The mixture of sand and corn meal was autoclaved for two successive days and then inoculated with 4-5 agar plugs of the 4 day-old fungus grown on PDA (potato-dextrose agar) at 30oC. Ten gr of inoculums was mixed thoroughly with the soil in each pot. Each soybean cultivar was six times planted in six pots, five seeds in each pot. Two pots were contaminated with isolate I and the other two with isolate II, while the last two pots being used as control (without any contamination). Microsclerotial propagules in lower stem and taproot tissues at growth stage R7 were used to determine INFECTION PERCENTage in cultivars. Analysis of variance showed that there were significant differences among cultivars as to the disease. Some cultivars were susceptible, while some being moderately resistant to T.phaseolina. Based on Duncan's multiple mean comparison test, cultivars NE 3297, Gorgan 3, M58, and Calhoan suffered the highest, while cultivars L93-3258, Macon, Probest and Salin the lowest INFECTION PERCENTage. Cluster analysis, performed on cultivars for INFECTION PERCENTage, placed cultivar NE3297 in a separate cluster.

Introduction: The risk of being affected by infectious diseases in dentistry directly depends upon the degree of contact with body liquids, such as blood and saliva, as well as the working tools. Different micro-organisms including the viruses causing AIDS and Hepatitis B as well as oral thrush are possible to be transferred in dentistry. According to the Dental intervention (FDI), it is suggested that all dental patients, in spite of the healthy look, are considered to be infective. Therefore, the health principles and protective and safety methods must be observed in all the sequences to prevent cross-INFECTION. Thus, the present study seeks to investigate the degree to which the dentists in Isfahan respect and approach to such standards.Materials and Methods: This is a cross-sectional descriptive study. In order to answer the questions of the study (as found in tables 1&2), the data related to the participants’ attitudes and performance were collected by having them fill out a questionnaire and a checklist. A total of 140 dentists in Isfahan were selected through a random sampling in 1385 (HS). The data collected was then evaluated with SPSS.Results: The mean score obtained from the attitude-related questions was 5.36. Also, the mean score of performance-related questions was found to be 8.03. No significant relation was found between the dentists` attitudes and the years of service (P=0.092, r=0.17). No significant relation was found between the dentists` performance and the years of service (P=0.12, r=0.15). No significant relation was found between the dentists` attitudes and their performance (P=0.1, r=0.16).

The effect of fat PERCENT at four levels (0.1, 1.19, 2.40 and 3.26%) on dynamic behavior of permeate flux (JP), total hydraulic resistance (RT) and mild solutes rejection (protein, RP; fat, RF; lactose, RL; minerals, RM and total solids, RTS) have been studied. Experiments were carried out using the pilot plant UF membrane system equipped to a spiral wound module and a polysulfoneamide membrane. A three-stage strategy based on an resistance-in-series model (boundary layer-adsorption) was used to determine the different hydraulic resistances. The results showed that the JP decreases greatly with increasing process time(t), but increasing fat PERCENT only led to intial flux decline and it had no effect on pseudo steady state flux. RT increased during operation at all levels of fat PERCENT. However RT, concentration polarization resistance, adsorption resistance and membrane hydraulic resistance did not change with increasing fat PERCENT. The rejection results shwed that the RP and RF were constant at each value of fat PERCENT and process time, whereas the RL, RM and RTS significantly increased.

Although corruption has a long history, it has been the subject of more attention at national and international levels in two recent decades. Corruption may manifest itself in numerous forms, including receiving financial advantages by purchase functionaries in governmental transactions. The crime is prosecuted as the crime of taking PERCENT in our criminal laws. The relevant international instruments do not allocate an independent title for this crime and it is merged under the general title of corruption. The main aim of this article is to consider Iran's criminal policy towards this crime. An attempt is made to illustrate whether Iranian criminal policy in this field is unilateral and repressive and whether Iran's criminal policy attends to the scientific findings in this field. A reference to international measures will also be made where appropriate.

Background: The aim of this study was to compare the effect of sodium chloride 5 PERCENT and methyl cellulose 2.5 PERCENT in the treatment of corneal edema after cataract surgery using phacoemulosification method.Methods: In a clinical trial study, 70 patients with corneal edema underwent phacoemulsification surgery. They were randomly divided in two groups of 35 patients. Sodium chloride 5 PERCENT drop in the first group and methyl cellulose 2.5 drop in the second group were administered every three hours and corneal thickness was measured before and 1, 4, 8, 15 and 30 days after surgery and compared in the two groups.Findings: No statistical difference between the two groups was found regarding decrease in corneal edema, but speed of decreasing was faster in methylcellulose group. At 4th day after the surgery, the amount of edema decreasing in sodium chloride group was 5.00 PERCENT as well as 12.19 PERCENT in methyl cellulose group and the difference between the two groups was significant (P<0.001).Conclusion: Using of methyl cellulose 2.5 PERCENT in treatment of corneal edema after cataract surgery with phacoemulosification method can decrease edema in shorter time than sodium chloride. So we recommend using of methyl cellulose if not contraindicated otherwise.

Background. Warts are a common skin disease affecting individuals of all ages worldwide. This clinical trial aims to compare the effectiveness of furosemide 0. 125 PERCENT topical gel and KOH 10 PERCENT topical gel in treating patients with warts. Methods. Patients diagnosed with warts by dermatologists were included in the study and treated with either 0. 125 PERCENT furosemide or 10 PERCENT KOH for two months. Patients were examined and imaged at the beginning of the study and in weeks 4 and 8 to assess the number, diameter, and height of warts and complications. Results. The study included 40 patients (48 lesions) with common warts, with 20 patients in each intervention group. In the furosemide group, the average diameter of warts decreased from 4. 25 ± 1. 43 mm in the first visit to 4. 14 ± 1. 47 mm in the final visit. In contrast, the average diameter of warts in the KOH group decreased from 3. 89 ± 1. 67 mm to 3. 02 ± 1. 49 mm. No complications were reported in the furosemide group, whereas seven complications related to redness and burning were observed in the KOH group. Conclusion. Furosemide 0. 125 PERCENT is effective and safe for treating skin warts. However, it is less effective than KOH in reducing the diameter and height of warts. This study's findings suggest that furosemide can be a promising alternative to KOH in treating warts, especially for patients with sensitive skin or those who experience complications with KOH treatment. Further research is needed to determine the optimal treatment duration and dosage of furosemide for treating warts. Practical Implications. We can find new ways to reduce complications in treating warts.
