Background and Aim: Since proteasome is strongly considered to be involved in the development and progression of a wide variety of hematological malignancies in particular, multiple myeloma, blockage of this hemostasis system with different types of proteasome inhibitors seems to be a promising way of treatment for multiple myeloma. In this study, we investigated the effect of Kyprolis, a new irreversible proteasome inhibitor [PI], on the survival rate of multiple myeloma -derived KMM-1 cell line
Material and Methods: To evaluate whether inhibition of proteasome using Kyprolis could exert cytotoxic effect in multiple myeloma, KMM-1 cells were cultured with different concentrations [25-150 nM] of the inhibitor for 24 and 48 hours. Then trypan blue exclusion assay, MTT assay, flocytometric cell cycle analysis were performed and we evaluated gene expression changes associated with apoptosis
Results: The results of this study demonstrated that Kyprolis induced both cytotoxic and anti- proliferative effects on KMM-1 cells. This inhibitor is able to reduce the cell survival and metabolic activity in a dose- and also time-dependent manner [p = 0.001]. Moreover, we found that Kyprolis increased cell population in G1 phase of cell cycle to 52.33% probably through up-regulation of p73 gene expression [p = 0.05]. Exposing multiple myeloma cells to this proteasome inhibitor also led to induction of apoptosis probably through alterations in the gene expression of pro- and anti-apoptotic related genes [p = 0.05]
Conclusions: The results of this study clearly indicated that Kyprolis had anti-tumor activity against KMM-1 cells

Factor XIII deficiency [FXIIID] is an extremely rare hemorrhagic disorder with an approximately 12 higher incidence in comparison with reported global incidence of the disorder. A standard diagnostic algorithm was proposed by the International Society of Thrombosis and Hemostasis [ISTH] for FXIIID, however, due to the lack of investments all parts of this algorithm cannot be applied in Iran. Thus, this study presented a national algorithm for diagnosis of FXIIID in Iran. For presentation of a national algorithm, all previously published data about Iranian patients with FXIIID as well as practical methods for diagnosis of FXIIID were collected using Science Direct, Google Scholar and PubMed databases. With available facilities, an algorithm with regards to the laboratory assessment, clinical presentations as well as family history can be suitable for an on time and less expensive diagnosis of FXIIID in Iran. Since ISTH diagnostic algorithm is expensive and time consuming, an economical and more suitable national algorithm with regards to available equipment may reduce the rate of misdiagnosis and its life-threatening consequences

The aim of the present study was to investigate the effect of addition of soymilk on physicochemical, microbial, and sensory characteristics of milk fermented with Lactobacillus acidophilus. Soybeans were blended 1:5 w/v with distilled water. The prepared soymilk was added to milk in combinations of 20%, 40%, and 60%. Milk was used as the control. All the samples were sterilized and fermented with Lactobacillus acidophilus LA-5 as probiotics. Then, they were kept at C for 14 days. Microbial count, titratable acidity, pH, syneresis, color parameters and sensory evaluation were performed during the storage time. Results showed that all the samples possessed minimum effective dose of LA-5 on day 14, although a significant decrease in LA-5 was observed in the sample with 60% soymilk. In each experimental day, there was a noticeable decrease in the pH of the samples. Addition of soymilk to milk also significantly increased syneresis, particularly in samples with 60% soymilk. Sensory evaluations showed that scores of texture, mouth sense, aroma, and flavor of the samples with 40% and 60% soymilk were significantly lower than other samples. With respect to color, "L" value decreased significantly in the fermented product with 60% soymilk and the decrease was more pronounced with longer storage times. In conclusion, addition of 20% soymilk did not substantially alter physicochemical and sensory characteristics of milk while providing an appropriate growth culture for LA-5. The mixture of milk-20% soymilk can be introduced as a good probiotic product with lower lactose content and additional nutritional benefits. Key words: Probiotics, Milk, Soymilk, Lactobacillus acidophilus

Factor X[1] is the last enzyme in the clotting cascade. The gene of A chain is located on chromosome 6. Deficiency of factor XIII in autosomal recessive conditions occurs at a frequency of 1 in 2 million general population. The aim of this study was to detect the mutations of subunit A in both patients and carriers. In this study we have investigated the molecular basis of inherited FXIII deficiency among patients from 21 unrelated Iranian families. Mutation were detected by amplifying each exon. Those exons exhibiting the presence of hetero duplex formation sensitive gel electrophoresis, were selected for direct sequencing. After sequencing, detected mutation was carried out by restriction fragment length polymorphism [RFLP]. All patients having entered the study had mutations. Twelve patients had homologues substitution of TGG->CGG in exon 4, 1 insertion mutation occurring in exon 7 triple G, 2 patients demonstrated mutation exon 9 ATG-> AAG, 3 patients had substitution of CGG-> CAG in exon 10, and 3 patients showed a homologue subsituation mutation in exon 15 GCC->GTC. Our findings suggest that the activity of enzyme is highly dependent on the core domain. Changes in charge, amino acid tail and conformation lead to decreased enzyme activity. Also tetrameric structure is calcium related. It seems that changes of amino acid sequence convert enzyme stability

The aim of the present study was to investigate the effect of glucose and glutamine supplementation on two serum growth factors, GH and IGF-I, in non-athlete males during four weeks of exhaustive endurance - intermittent training that causes glycogen depletion. 20 non-athlete healthy males were selected and randomly assigned into four groups including: glucose supplementation with glycogen depletion training group [n=5, supplement 1], glutamine supplementation with glycogen depletion training group [n=5, supplement 2], glycogen depletion training group [n=5, placebo], and a group without any treatment [n=5, control]. The blood samples were collected at the onset of the training protocol, and 48 hours after final training session from anticubital venous. Serum GH and IGF-I concentration were determined by ELISA technique. The main and interaction effects of variables were determined using TWO WAY ANOVA compeleted with Tukey post-hoc test. The significant level was chosen as alpha =0.05. The results showed the significant effect of training variable for serum IGF-I concentration, [p<0.01]. Post-hoc test showed the significant difference between supplement 1 with control groups [p<0.01], and placebo with control [p<0.01]. The effect of training variable was not significant for serum GH concentration. In addation, the effect of supplementation variable was not significant neither for serum IGF-I, nor serum GH concentration. Also, the interaction effect between the two variables was not significant. The results suggested that glucose or glutamine supplementation does not have significant effects on serum GH and IGF-I concentration after four weeks, but four weeks glycogen depletion training causes an increase on the serum IGF-I

Technology development has brought about the society with a sedentary life style and an increase in number of chronic diseases. Therefore, to change the pattern of physical activity in adolescents, the recognition of factors affecting such activities is of crucial importance. The aim of this research was to investigate the relationship between the pattern of physical activity in adolescent girls and their mothers' physical activities, attitudes, and some demographic characteristics. This cross-sectional stud was carried out on adolescents 226 girls aged 11-18 years in 2010. The study population was chosen using a cluster sampling method. Data were collected using a questionnaire of three sections including demographic data, adolescent's physical activity pattern, and attitude and pattern of physical activity in mother. Data were analyzed using chi-square test and Pearson correlation coefficient. Of 226 girls, 50% found to have 2.07 hours of moderate to strong physical activity while 26.5% with a sedentary life style. A significant relationship between the adolescents' physical activity pattern and the mother's physical activity and regular exercise was demonstrated [p<0.005]. Also, there was a significant relationship between the adolescents' regular exercise and the mothers' exercise. Statistically, a significant correlation between the mothers' attitude and educational degree and the level of physical activity was shown. According to our results, a sedentary life style among female adolescents is higher than expected which is associated with mother's pattern of physical activity and affected by the attitude and educational level of mothers. Therefore, it is recommended that part of the educational programs to increase the level of daily physical activity in adolescent girls to be focused on mothers

Trichomoniasis is a worldwide protozoan parasitic disease. Considering the importance of the disease in public health and the controversial ideas about the prevalence of drug resistance, this study was designed to determine the prevalence of metronidazole resistance gene in trichomonas vaginalis [T. vaginalis] with PCR-RFLP method in Tehran and in Kashan. In this descriptive study 140 samples of T. vaginalis in patients with T. vaginalis infections were collected and assessed microscopically. Then they were isolated and examined by culturing in dorset's medium, DNA extraction and PCR amplification. The PCR products were analyzed using RFLP and suspected samples were sequenced. All but 7 samples were T. vaginalis positive by PCR. Sixty-two samples [44.4%] were examined by microscopic, culture and PCR techniques; 12 samples [8.5%] by microscope and PCR, 56 samples [40%] by culture and PCR and other 3 samples [2.1%] were positive only by PCR. Two samples [1.5%] were also examined for detection of mutation in 18S rRNA gene with RFLP in Tehran. This study shows that T. vaginalis infections in the female population living in Tehran are metronidazole-resistant. Since metronidazole is considered as the drug choice for T. vaginalis infections, more studies are recommended for identification of the drug resistance mechanisms and prevention of the disease

Introduction: Autonomic neuropathy is a rare disorder inherited as insensitivity to pain and temperature. It has been divided into five groups, the fourth of which named congenital insensitivity to pain with anhydrosis, [CIPA] is the most common type of this disorder. CIPA is a recessive inherited condition with courses of idiopathic fever, reduction of sweat glands secretion despite having normal glands, insensitivity to pain and temperature changes, and mild mental retardation. Oral symptoms due to their severe abuse in these patients are considerable. Gas shock tongue, lips and other oral mucosa have been reported
Case Report: Examination of a 15 month old boy revealed severe oral ulcers and burns in the fingers of both hands due to contact with the heater. Pathological studies and special attention to specific aspects of the patient revelead that he was insensitive to pain and thermal stimulation and was diagnosed as a possible case of CIPA
Conclusion: CIPA is a autosomal recessive disorder which is very rare in childhood, as insensitivity to pain or the incidence of abuse and lack of objective response to pain in people with peripheral and central nervous system are normal. Tyrosine gene defect related to gene code provided membrane tyrosine has been identified in these patients. Mutation in this gene results in insensitivity to pain, anhydrosis, self abuse, and mental retardation and is associated with cancer. More than half of the patients die before the age of three. Oral manifestations of this syndrome are the characteristics of the disorder and can help to make an early diagnosis

The purpose of this study was to determine the response of some immune and inflammatory markers of cardiovascular disease to a single, short intense duration of exercise, in prepubertal overweight boys exercise. To do this, 13 students 11-14 years-old were selected randomly from among voluntary subjects. In the preliminary session VO2max [26.9 +/- 4.9 ml/kg/min], weight [77.07 +/- 17.33 kg], height [1.65 +/- 0.08], fat percent [31.7 +/- 5.6 percent], body composition, BMI [28.9 +/- 3.5 kg/m2], skeletal age [12.4 +/- 0.9 years] with X-ray, pubertal age with Tanner-stage [T3, T4] was measured and determined familiar illness was done four day before experimental session. In the experimental session, firstly, pre-exercise blood sample collected in fasted state, and then every subject on the ergometer cycle started cycling with 65-70% VO2max for 40 min, post 5 min warming, with 5 min cool down at the end of the program. Immediately post-exercise and recovery blood samples were drawn for measurement by a cell counter employing Isotone Soluble technique, while for hs-CRP and IL_6, we used the immunometric assay Eliza kit. Data were analyzed using the analysis of variance with repeated measures [R-ANOVA] test. The results showed there was a significant relation between different blood samplings. The post hoc [LSD] test that showed neutrophils count and hs-CRP and IL-6 levels one hour after exercise statistically was more than pre-exercise [p=0.001, 0.01, 0.01, respectively] also lymphocyte, monocytes, neutrophils counts and IL-6 level immediately post-exercise [p=0.05, 0.01, 0.004, 0.01, respectively]. Exercise may initiate the response of inflammatory and immune factors in prepubertal obese boys, and increase levels of these factors. This study indicates that a single intense bout of exercise with 65-70% Vo2max can increase subgroups of with blood cells, C-reactive protein and IL-6 in immature obese and overweight children, intense exercise can be activate immune and inflammatory system and increase levels of some of the cited factors
