Phorbol 12-myristate 13-acetate (PMA) Alters Galectin Gene Expression in Cows

Galectins (GAL) are β-galactoside binding proteins. The objective of this study was to assess the effect of PMA on the regulation of galectin gene expression in bovine blood and neutrophils. Blood was collected from 3 clinically healthy Holstein cows. Neutrophils were isolated by differential centrifugation. Blood and neutrophils were treated with 10ng/ml of PMA or maintained in phosphate-buffered saline for 30 minutes at 370 C. Pooled total RNA were transcribed to cDNA for real-time PCR. Specific primers for bovine LGALS -1, -2, -3, -4, -7, -8, -9, -11, -12, and their binding proteins (bp) LGALS3bp, T cell immunoglobulin and mucin domain 3 (TIM-3) were used. Housekeeping genes RPLP0 and UCHL5 served as internal controls. Fold changes were calculated using the Livak method. Total protein concentration was assessed using the Bicinchoninic acid assay. Secretion of GAL -1, -2, -3, -4, -8, -9 was assessed using bovine GAL specific ELISA. All tested LGALS were detected. Activation with PMA differentially modulated expression and secretion of GAL in blood and neutrophils. Expression levels of LGALS -1 and LGALS -3 was not affected. Expression of LGALS -7, -8, -9, -11, -12, and TIM-3 was differentially modulated. The secretion of GAL -3 was significantly increased in response to PMA. The most pronounced effect of PMA was observed on LGALS-9, TIM-3 expression, and the secretion of GAL -3. Thus, GAL may serve as biomarkers of cell activation with functional consequences and warrant further study.

Evaluation the Recurrence Risk of Gestational Trophoblastic Neoplasia (GTN) after Serum βhCG Normalization

Background: Although many GTN patients can be treated with chemotherapy, a small proportion of them will relapse after complete recovery. To the best of our knowledge, there is not any information in respect of relapsed GTN cases in our region. In the current study we have aimed to evaluation of the recurrence risk of gestational trophoblastic neoplasia (GTN) after serum βhCG normalization Methods: This descriptive-analytical study was carried out on registered hospital data of patients with confirmed GTN diagnosis following molar pregnancy who admitted to the gynecology ward of Imam Khomeini Hospital between 2011 and 2017. Patients with diagnosis of postmolar GTN, based on at least five bhcg measurements was included. Patients information including initial level of serum BhcG, time to Bhcg resolution, types of molar pregnancy, treatment protocols, need to recuretage relapse, and finally, the period time between bhcg resolution to relapse were evaluated. Results: In the present study, 239 patients with GTN (including 180 complete and 59 partial moles) were evaluated. The mean age of the patients was 28.8 years, ranging from 16 to 47 years. The mean βhCG concentration was 170,000 IU/ml (ranged 760 to 850,000). The mean time of βhCG resolution was 8.19 months in the range of 4 to 12 months. Recurrence was observed in 9 patients (3.7%). The mean period time between βhCG resolution to relapse was 20.94 months. The mean initial level of βhCG was significantly lower in patients with recurrence (p <0.0001). The highest recurrence rate was seen in those receiving multiple-drug chemotherapy. There was also a significant relationship between disease stage and recurrence rate. Conclusion: The findings of this study indicate that although the recurrence of GTN is relatively low, given the poor prognosis of these patients, continuous evaluation of bHCG levels for at least two years is essential to prevent disease progression.

Prevalence of Malnutrition (Overweight and Underweight) in Children Aged 10-13 Years in Schools in Manipal and Utopia, Karnataka

Background. Malnutrition is a major health problem in India. It mostly affects children of school going age with serious health problems putting them at an increased risk for developing chronic diseases later in life. This study aims to study the prevalence of malnutrition (overweight and underweight) in children aged 10-13 years in schools in Manipal and Utopia, Karnataka. Materials and Methods. In this study, a total 400 students were studied. Their anthropometric measurements like height, weight, BMI and MUAC, dietary pattern, physical activity level, and child eating behavior. Questionnaire was used to note the student’s information. The data collected was subjected to statistical analysis using SPSS version 21, Diet Cal, and Anthroplus1.0.4. Results. It was observed that in the childhood category 10-13 years there were 222 (55.5%) male and 178(44.5%) female. According to the BMI for age 53.4% of them falls under the normal category; 22.3% falls under the mild wasting category; About 18.3% falls under the obese category and 8% falls under the moderate wasting category. There is no students falling under the severe wasting and overweight category according to the BAZ classification. When the height for age was done for all the children, about 36.3% falls under normal height; About 35.5% falls under mild stunting; 19.3% falls under the moderate stunting; 8.3% falls under the severe stunting category; and 1% falls under tall category according to the HAZ classification. Conclusions. In conclusion, mild stunting and wasting was observed among children. There are no students falling under the severe wasting and overweight category according to the BAZ classification.

Assessment of the Consistency of Tetabulin Injection to the Patients with an Open Fracture Referred to the Khatamolanbia Hospital, Zahedan in 2017 with the National Guidelines

Background and Goal: Open fractures are at risk of infection with Clostridium tetani and severe traumatic infections. Tetabulin injection is strongly recommended for the patients with an open fracture and severe wounds. The goal of this study is to assess the consistency of tetabulin injection to the patients with an open fracture referred to the Khatamolanbia hospital in Zahedan in 2017 with the national guidelines. Materials and Methods: This study is a cross-sectional descriptive study. 300 patients with an open fracture referred to the ER of the Khatamolanbia Hospital in Zahedan in 2017 were selected as the sample. Their fracture type and severity were assessed. The data were classified in the tables and statistically analyzed using Chi-square, pared t-test, Pearson correlation, and regression in SPSS 26. Findings: Among 300 patients, 275 patients (91.7%) were male and 25 patients (8.3%) were female. The most frequent age range was 20 to 30 years old (31.7%), and the least frequent ones were 5 to 10 years old (10%) and more than 50 years old (11.6%). The results showed that gender has no significant effect on the predictability of the need of tetabulin injection for the patients with open fractures (P=0.780). However, age has a significant positive effect on the predictability of the need of tetabulin injection for the patients with open fractures; as the age increases, the need for tetabulin injection also increases, and it must be injected in the 50 years and older patients (P=0.05). Conclusion: The results showed that age was effective on the decrease of the serum level of anti-tetanus antibody, however, gender had no significant effect on it. Therefore, it is concluded that tetabulin injection for open fractures is consistent with the national guideline.

The Association between Sex Hormones and Developmental Stuttering Disorder: A Systematic Review

Stuttering is a male-biased speech motor control disorder that lead to disruption in the rhythm of speech. The effect of sex on development of stuttering is well known; males are more susceptible to and less recovered from stuttering than female. Sex hormones have been studied as a main accused factor for this gender dependency of the disorder. The aim of this systematic review is to navigate the extent of previous research about the relationship of developmental stuttering and sex hormones. Toward these ends, a comprehensive, electronic review of past concepts regarding the relationship of stuttering with sex hormones and digit ratio as an indirect index for fetal testosterone exposure, in Scopus, Science Direct, PubMed, Medline, Embase, and Cochrane database was carried out to identify potential studies for the review. Inclusion criteria were original quantitative research, written in English, used human subjects and published from 2000 through 2020. Findings were mixed, although potential patterns were identified. There were methodological limitations such as small participant numbers, in the targeted population in this review research. The findings from this current study add to the growing body of evidence demonstrating that sex hormone have a significant association with stuttering.

The Curative Effect of a Second Curettage in Low-Risk Gestational Trophoblastic Neoplasia

Background: Gestational trophoblastic neoplasia (GTN), despite its widespread metastases, is a very common cancer in women that is curable. Although the GTN cases show a good response to chemotherapy, in an effort to reduce toxic drug exposure, the second curettage has been suggested for some patients. In the current study, we have aimed to compare the benefits of the second curettage in comparison with single-agent chemotherapy for low-risk GTN patients. Methods: This retrospective observational study was carried out on GTN patients admitted to the gynecology department of Imam Khomeini Hospital in Ahvaz. The demographic profile of all participants was extracted. Patients' hospitalization records were also extracted from the files. Patients with an endometrial thickness above 10 mm were treated with re-curettage. The β hCG clearance time was estimated by the Kaplan Meier plot. Results: In the present study, 148 patients with low-risk GTN stage 1 were studied. The time required for β-hCG clearance in patients undergoing re-curettage was significantly lower than the chemotherapy receiving group (7 months vs. 10 months, p <0.0001). More than 50% of patients treated by re- curettage without needing chemotherapy. Moreover, the other 50% cases needed chemotherapy the number of courses was significantly lower than those received single-agent chemotherapy alone (p <0.0001). The baseline β-hCG levels were significantly lower in those who did not need chemotherapy (p = 0.012). β-hCG resolution occurred more rapidly in patients undergoing re-curettage alone, while, those who received only chemotherapy had a longer duration for β-hCG clearance. Conclusion: In general, the findings of this study showed that re-curettage could be used effectively in the treatment of GTN following molar pregnancy. This treatment reduces or eliminates the need for chemotherapy. Our findings also showed that the initial level of β-hCG could be considered as a predictive factor in response to curettage.

The Effect of TNF-α on the Expression of MMP9 in Human Mesenchymal Bone Marrow-Derived Stem Cells

Matrix metalloproteinase 9 (MMP9) as the enzyme of adult stem cells secreted from damage cells. In spite of low level of MMP9 enzyme in the mesenchymal stem cells, many inflammatory cytokines stimulation such as TNF-α could increase MMP9 level in cells. Current study evaluated the expression of the MMP9 enzyme under the influence of TNF-α in human bone marrow mesenchymal stem cells. The human bone marrow mesenchymal stem cells were classified into control and experimental groups. In the experimental groups, various concentrations of the TNF-α (1ng/ml and 10ng/ml) were administrated in different times (10 and 24 hours), whereas the control group was not treated with TNF-α. MMP9 gene expression was evaluated by Real-Time PCR. TNF-α administration in 1ng/ml and 10ng/ml dosage for 10 hours, induced the expression of MMP9 1468.3 and 1782.8 times more than the control group, respectively. After 24h, in comparison between 1ng/ml and 10ng/ml with control groups, MMP9 expression were 442.64 and 1184.4 times more than control group, respectively. In conclusion, the expression rate of the MMP9 gene in bone marrow mesenchymal stem cells might be effected by dosage and time of exposure to TNF-α. Furthermore, the time of exposure might have the prominent role in alteration of MMP9 gene expression induction in the mesenchymal stem cells.

Study of the Relation between Parenting Style and Attitude with Physical Activity, Diet Behavior and Health of Children (10-13 Years): A Descriptive Cross - Sectional Study

Background. Due to the significant and Irrefutable effects of parental style on children and the lack of a comprehensive studies on this topic, the present study aimed to study the relation between parenting style and attitude with physical activity, diet behavior and health of children (10-13 years). Materials and Methods. This study is a descriptive cross - sectional study and conducted in schools located in Manipal and Udupi (Karnataka, India) during May 2017 to November 2017. A well designed questionnaire was administrated to children which included general information, along with physical activity questionnaire. The questionnaire also comprised of various other anthropometric measurements like BMI, MUAC, and Waist hip Circumferences etc. The data collected was subjected to statistical analysis using SPSS version 21. BMI has been calculated using anthroplus 1.0.4. Results. The results of this study showed that there is a significant relationship between parenting style and diet behavior of the child (P< 0.001). Parents with stylistic dimension in both authoritative and authoritarian have more influence on child for food avoidance and food approach. Studies shows an association between authoritarian and permissive parenting style with food approach behaviors and child weight status of children. parenting style is not affected on Childs physical activity. 74.8% of variation in weight is explained by the independent factors like parenting style, Nutrient intake, Food group intake, Physical activity level, Anthropometric measurement, and child eating behaviour questionnaire. There was a significant relationship between weight and these factors at 1 % level (F=32.889, P< 0.001). Conclusions. In conclusion, parents with stylistic dimension in both authoritarian and permissive style of parenting and parents with stylistic dimensions in all type of parenting style influences child physical activity. Parents with stylistic dimension in both authoritative and authoritarian have more influence on child for food avoidance and food approach behavior.

Comparison of Clinical and Radiographic Periodontal Status between Hookah and Cigarette Smokers

Background and Objective: Inhalation of chemicals and toxins in cigarette and hookah smoke results in loss of integrity of oral cavity tissues. The objective of this study was to compare the periodontal health of hookah and cigarette smokers. Materials and Methods: In this study, 73 men at the age group of 20-35 years who smoked hookah for more than 5 years and 73 men at the same age who smoked cigarette for more than 5 years and 73 healthy men referred to the periodontal department of Mashhad dentistry school were selected and studied. Periodontal indices including pocket depth, GI, BOP, CAL were assessed in two groups. Also, using parallel periapical radiography, mesial and distal marginal bone level around the first molar tooth was measured. Finally, the data were assessed and compared using appropriate statistical analysis. Results: Pocket depth was 24.27% and 23.62%, respectively, in cigarette smokers and hookah smokers, and it was 0.96% in healthy subjects, clinical attachment level was 4.48 and 4.41 mm, respectively, in cigarette smokers and hookah smokers, and it was 0.77 mm in healthy subjects. Gingival index (GI) was 1.40 and 1.42, respectively, in cigarette smokers and hookah smokers and it was 0.52 in healthy subjects, BOP value ​​was 6.52 and 6.52%, respectively, in cigarette smokers and hookah smokers and it was 10.86% in healthy subjects. Mesial marginal bone level of first lower molar tooth was 2.27 and 2.32 mm, respectively, in cigarette smokers and hookah smokers and it was 1.74 mm in healthy subjects and distal marginal bone level of lower first molar tooth was 2.38 and 2.35 mm, respectively, in cigarette smokers and hookah smokers and it was 1.75 mm in healthy subjects. Comparison of results between the two groups of cigarette smokers and hookah smokers did not show any significant relationship in any of the variables, but there was a significant relationship between the two groups and the healthy group (P <0.001). Conclusion: Periodontal parameters in healthy individuals are significantly better than those of smokers. Also, although there is a relationship between cigarette smoking and hookah smoking and periodontal parameters, these two groups do not show a significant difference in terms of periodontal parameters.
