Authors: Elhampour Laleh , Azarbayjani Mohammad Ali , Nasehi Mohammad , Peeri Maghsoud
Published: December 2019

Background: Exercise and Curcumin have positive effects on spatial memory and cognition independently. The present study aims to investigate whether the combination of ineffectual dosage of these factors can affect cognition and as a solvent if DMSO is involved in Curcumin effects. Materials and Methods: Male NMRI mice (1-month-old) swam (1 week) for 60 minutes (5days/week) and injected with morphine (2.5 mg/ml/kg, intraperitoneal) for five days. Spatial learning and memory were assessed by Moris Water Maze test on the 10th day after stopping morphine injection. Results: The findings revealed that exercise, dimethyl sulfoxide (DMSO), and Curcumin increased memory formation induced by 2.5 mg/ml/kg morphine. DMSO+exercise decreased memory formation induced by morphine, but curcumin +exercise could return the effect of DMSO on the cognition. Conclusion: As a solvent, DMSO had independent effects on memory, which lead to memory impairment in combination with exercise. Therefore, considering its unpredictable effects on cognitive performance, it should be replaced with another solvent or might be used carefully in behavioral experiments. [GMJ.2019;8:e1072]

Published: December 2019

Background: Pregnancy is one of the most sensitive periods in a woman’s life, which sexual activity and intercourse are affected by the variations in physical, hormonal, and mental conditions. This study aimed to investigate the factors affecting the variations in sexual response before and during pregnancy. Materials and Methods: This cross-sectional study was conducted on pregnant women at Rasht city (northern Iran), 2018. The data were collected using the pregnancy sexual response inventory (PSRI). Statistical analysis was performed using descriptive and inferential tests by SPSS 25 at a significance level of P<0.05. Results: The mean total score of sexual activity and response of the subjects before and during pregnancy were 73.04 ± 14.81 and 46.88 ± 16.51, respectively. The variations in the total score of sexual activity and response during pregnancy decreased by 26.16 points during pregnancy compared to before pregnancy. There was a positive correlation between the number of children and the score of the variations in sexual activity and response before and during pregnancy (r=0.143). Conclusion: Couples with a higher level of education and a lower number of children had fewer variations in their sexual response. Therefore, it is possible to enhance the couples’ sexual health through encouraging them to appropriately plan for childbearing, to share the responsibilities of taking care of their children, and to continue their education at higher levels.

Published: December 2019

The development of a variety model suitable for specific soil and climatic conditions is currently an urgent matter in the plants selection. The combination of valuable genotypes of a plant, which is based on hybridization, free pollination, mutagenesis, allows researchers to derive new perspective samples. The selection of the variety model parameters enables the researchers to create cultivated plant varieties that have appropriate characteristics of a particular cultivation zone on an efficient basis. But it is necessary to understand that the model is hypothetical even in case of conducting detailed study of parameters of a new variety based on concrete results of research. First of all, the crop breeder is guided by the imaginary model, which is based on the evaluation of the breeding material and the selection of the variety sample prototype, taking into account the features and properties of the ideal variety model. To a certain extent, the methods of crop breeding and genetic analysis applied in order to assess the breeding value of hybrid combinations are designed to level the inevitable subjectivity noted. When compiling the model of the ideal variety the breeder uses the data on soil and climate conditions of a particular region, the main economic and valuable features of a crop, the results of other researchers and applies intuitive and empirical criteria for evaluating the breeding material. Since 1997 the Chair of Breeding, Genetics and Forestry explored more than 150 breeding samples of different ecological-geographical origin, obtained on the basis of intervarietal hybridization. The samples were studied according to the main economic and valuable features: growing season, growth character, presence of parchment layer and fibers in the seam. Variability of the mentioned features has been estimated by means of correlation links and character of inheritance of separate features.

The paper demonstrates the research results on somatic chromosomal instability that includes the number of chromosomal fragments in the blood cells of the ram descendants, obtained from Romanov servicing rams. The research was carried out on the populations of Romanov sheep at OAO “Vaganovo” in Promyshlennovsky district of the Kemerovo region. The samples were prepared by means of the P. Murkhed method and stained using the Romanovsky-Gimza method. 2580 metaphase blood plates of lambs were studied. The authors analyzed the environmental situation in the breeding area. Studies of soil, fodder, organs and tissues of the animals of different species confirm that there are no heavy metal pollution within the sanitary protection zones in Western Siberia. The authors found out the hereditary regularities of somatic chromosomal instability in the Romanov sheep. The researchers identified the impact of servicing rams genotype on the quantity of fragments of chromosomes in the blood cells of the offspring. The differences in phenotypic variability were revealed in the offspring of different ram-males. The paper shows that the number of chromosome fragments in the sons of some fathers was 3.2 times higher than in the descendants of other servicing rams. Due to the lack of the data on somatic chromosomal instability, the number of chromosomal fragments in the cells of Romanov sheep in Siberia, the data obtained can be accepted as a physiological standard, as well as used to characterize animal interior.

The paper shows the results of biochemical analysis of the protein status of Kemerovo pigs. The research was carried out at OOO Chistogorskiy in Kuzbass. The blood samples from pigs were taken by means of the standard methods and analyzed in the laboratory of veterinary genetics and biochemistry of Novosibirsk State Agrarian University. The researchers used standard tools for biochemical tests on the biochemical semi-automatic analyzer Photometer 5010 V5+. The concentration of some protein metabolic parameters was characterized by a standard distribution: total protein (p-value=0.85), albumin (p-value=0.06), and globulin (p-value=0.65). The average values of total protein and albumins varied in standard intervals, except for the level of globulins, which was significantly lower than the reference values set for pigs. It was seen as one that had the greatest individual fluctuations (44%). The urea concentration was slightly lower than the physiological standard and was characterized by a rather high level of individual variability (50%). The researchers found that uric acid concentration was 3.2 times lower than the standard one in the investigated pigs. The authors observed the interbred differences in the content of total protein and albumin comparing the Kemerovo, Chistogorsk and early maturing pig breeds (CM-1). The correlation analysis has shown that there is a high positive correlation between total protein and globulins (r=0.88). The average positive relation between urea and uric acid was (r=0.58). The obtained data on protein metabolism is one of the basic characteristics of the Kemerovo pigs interior.

Published: December 2019

The authors investigated the effect of probiotic Vetom 1 based on Bacillus subtilis strain DSM 32424 with concentration of active component 106 CFU/g on cumulative indices of Japanese quail egg-laying. The specimen was applied in doses of 50, 75 and 100 mg/kg of the live weight of quails. The probiotic Vetom 1 increases the number of ovulating birds. The maximum increase in this indicator was observed when using Vetom 1 dosed as 50 mg/kg of the body weight. The egg mass variability depends completely on the dose. Being used in a dose of 50 mg/kg weight, a higher variability of the egg mass was observed. This pattern has not been recorded in the maximum studied dose. The cumulative function in terms of eggs in unit and mass equivalents is slightly expressed in the initial period when applying Vetom 1. In the final period of specimen applying, the highest accumulation is observed when using Vetom 1 in a dose of 50 mg/kg of mass. When applying Vetom 1 in doses of 75 and 100 mg/kg, a direct correlation between ovulation frequency and egg weight was observed only in the initial period of the specimen applying, and the dose of 50 mg/kg - only for the eighth day of it.

The researchers investigated the effect of new probiotic Vetom 1 based on apathogenic bacilli on the biochemical parameters of blood serum, exactly protein, albumins and urea in lactating cows. The experiment was carried out at OOO “Uchkhoz Tulinskoe”. According to the principle of pair-analogues, the researchers arranged a control group and two experimental groups of cows; each group contained 7 cows. The cows of the 1st experimental group were fed with probiotic Vetom 1 dosed 50 mg/kg once a day in the morning before milking; They received Vetom 1 every day during 5 days, then in a day during a month. The cows from the 2nd experimental group received probiotic Vetom 1 dosed 50 mg/kg once a day in the morning before milking, every day during 30 days. The application of the specimen contributed to a decrease in the concentration of total protein in the blood serum within the physiological norm. The aftereffect caused by Vetom 1 when the specimen was applied 5 days every day, then in a day during a month, the authors observed an increase in the concentration of total protein in the blood serum above the physiological standard on the 180 day of application. The similar effect was not observed when Vetom 1 was applied daily. When using Vetom 1, the authors observed a slight increase in the concentration of albumins in the blood serum, both during the period of application and up to 180 days. The specimen contributes to less prominent increase in the concentration of urea in the blood serum in comparison with the control group. Changes in concentrations of albumins and urea occurred within the physiological norm.

OBJECTIVE

Mechanical thrombectomy is the established treatment for acute ischemic stroke due to large vessel occlusion (LVO). The authors sought to identify early predictors of a favorable outcome in stroke patients treated with mechanical thrombectomy.

METHODS

Consecutive patients with ischemic stroke due to LVO who underwent mechanical thrombectomy at a Comprehensive Stroke Center in the US between 2016 and 2018 were retrospectively reviewed. Demographics, stroke and treatment characteristics, as well as functional outcome at 90 days were collected. Clinical predictors of 90-day functional outcome were assessed and compared to existing indices for prompt neurological improvement. Analyses of area under the receiver operating characteristic curve were performed to estimate the optimal thresholds for absolute 24-hour and delta (change in) National Institutes of Health Stroke Scale (NIHSS) scores for functional outcome prediction.

RESULTS

A total of 156 patients (median age 71.5 years) underwent 159 mechanical thrombectomies. The M1 segment of the middle cerebral artery was the most frequent site of occlusion (57.2%). The median NIHSS score before thrombectomy was 18 (IQR 14–24). A postthrombectomy Thrombolysis in Cerebral Infarction score of 2B or 3 was achieved in 147 procedures (92.4%). The median NIHSS score 24 hours after thrombectomy was 14 (IQR 6–22). Good functional outcome at 90 days (modified Rankin Scale score 0–2) was achieved in 37 thrombectomies (23.9%). An absolute 24-hour NIHSS score ≤ 10 (OR 25.929, 95% CI 8.448–79.582, p < 0.001) and a delta NIHSS score ≥ 8 between baseline and 24 hours (OR 4.929, 95% CI 2.245–10.818, p < 0.001) were associated with good functional outcome at 90 days. The 24-hour NIHSS score cutoff of 10 outperformed existing indices for prompt neurological improvement in the ability to predict 90-day functional outcome.

CONCLUSIONS

An NIHSS score ≤ 10 at 24 hours after mechanical thrombectomy was independently associated with good functional outcome at 90 days.

Published: December 2019

OBJECTIVE

The objective of this study was to assess the efficacy of unilateral pallidotomy in patients with asymmetrical cervical dystonia.

METHODS

This study retrospectively included 25 consecutive patients with asymmetrical cervical dystonia refractory to botulinum toxin injections, who underwent unilateral pallidotomy between January 2015 and April 2017. Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) scores were evaluated preoperatively and 1 week, 3 months, and 6 months postoperatively. The clinical responses were defined as good responders, exhibiting > 50% improvement in the TWSTRS score at 6 months postsurgery, or poor responders, exhibiting < 50% improvement in TWSTRS scores at 6 months postsurgery.

RESULTS

Twelve and 9 patients showed right- and left-side rotation, respectively; 1 and 3 patients had right- and left-side laterocollis, respectively. The mean age of onset and duration of the disease were 40.2 ± 13.9 and 8.9 ± 10.9 years, respectively. Mean TWSTRS scores were 38.4 ± 12.6 (p < 0.001), 17.3 ± 12.4 (p < 0.001), 19.5 ± 13.4 (p < 0.001), and 20.0 ± 14.7 (p < 0.001), preoperatively and 1 week, 3 months, and 6 months postoperatively, respectively. Fourteen patients (56%) demonstrated > 50% improvement in their TWSTRS total score (mean improvement of TWSTRS total score = 70.5%) 6 months postsurgically. Furthermore, preoperative TWSTRS severity score was a prognostic factor (odds ratio 1.37, 95% confidence interval 1.06–1.78, p = 0.003).

CONCLUSIONS

These results suggest that unilateral pallidotomy is an acceptable treatment option for asymmetrical cervical dystonia. Further investigations with a larger number of cases and longer follow-up period are required to confirm these data.
Sex-related differences in wall remodeling and intraluminal thrombus resolution in a rat saccular aneurysm model

Published: December 2019

OBJECTIVE

Intracranial aneurysms (IAs) are more often diagnosed in women. Hormones and vessel geometry, which influences wall shear stress, may affect pathophysiological processes of the arterial wall. Here, the authors investigated sex-related differences in the remodeling of the aneurysm wall and in intraluminal thrombus resolution.

METHODS

A well-characterized surgical side-wall aneurysm model was used in female, male, and ovariectomized rats. Decellularized grafts were used to model highly degenerated and decellularized IA walls and native grafts to model healthy IA walls. Aneurysm growth and thrombus composition were analyzed at 1, 7, 14, and 28 days. Sex-related differences in vessel wall remodeling were compared with human IA dome samples of men and pre- and postmenopausal women.

RESULTS

At 28 days, more aneurysm growth was observed in ovariectomized rats than in males or non-ovariectomized female rats. The parent artery size was larger in male rats than in female or ovariectomized rats, as expected. Wall inflammation increased over time in all groups and was most severe in the decellularized female and ovariectomized groups at 28 days compared with the male group. Likewise, in these groups the most elastin fragmentation was seen at 28 days. In female rats, on days 1, 7, and 14, the intraluminal thrombus was mainly composed of red blood cells and fibrin. On days 14 and 28, macrophage and smooth muscle cell invasion inside the thrombus was shown, leading to the removal of red blood cells and deposition of collagen and elastin. On days 14 and 28, similar profiles of thrombus reorganization were observed in male and ovariectomized female rats. However, collagen content in thrombi and vessel wall macrophage content were higher in aneurysms of male rats at 28 days than in those of female rats. On day 28, thrombus coverage by endothelial cells was lower in ovariectomized than in female or male rats. Finally, analysis of human IA domes showed that endothelial cell coverage was lower in men and postmenopausal women than in younger women.

CONCLUSIONS

Aneurysm growth and intraluminal thrombus resolution show sex-dependent differences. While certain processes (endothelial cell coverage and collagen deposition) point to a strong hormonal dependence, others (wall inflammation and aneurysm growth) seem to be influenced by both hormones and parent artery size.

OBJECTIVE

Acute subdural hematoma (ASDH) is a leading entity in brain injury. Rodent models mostly lack standard intensive care, while large animal models frequently are only short term. Therefore, the authors developed a long-term, resuscitated porcine model of ASDH-induced brain injury and report their findings.

METHODS

Anesthetized, mechanically ventilated, and instrumented pigs with human-like coagulation underwent subdural injection of 20 mL of autologous blood and subsequent observation for 54 hours. Continuous bilateral multimodal brain monitoring (intracranial pressure [ICP], cerebral perfusion pressure [CPP], partial pressure of oxygen in brain tissue [PbtO2], and brain temperature) was combined with intermittent neurological assessment (veterinary modified Glasgow Coma Scale [MGCS]), microdialysis, and measurement of plasma protein S100β, GFAP, neuron-specific enolase [NSE], nitrite+nitrate, and isoprostanes. Fluid resuscitation and continuous intravenous norepinephrine were targeted to maintain CPP at pre-ASDH levels. Immediately postmortem, the brains were taken for macroscopic and histological evaluation, immunohistochemical analysis for nitrotyrosine formation, albumin extravasation, NADPH oxidase 2 (NOX2) and GFAP expression, and quantification of tissue mitochondrial respiration.

RESULTS

Nine of 11 pigs survived the complete observation period. While ICP significantly increased after ASDH induction, CPP, PbtO2, and the MGCS score remained unaffected. Blood S100β levels significantly fell over time, whereas GFAP, NSE, nitrite+nitrate, and isoprostane concentrations were unaltered. Immunohistochemistry showed nitrotyrosine formation, albumin extravasation, NOX2 expression, fibrillary astrogliosis, and microglial activation.

CONCLUSIONS

The authors describe a clinically relevant, long-term, resuscitated porcine model of ASDH-induced brain injury. Despite the morphological injury, maintaining CPP and PbtO2 prevented serious neurological dysfunction. This model is suitable for studying therapeutic interventions during hemorrhage-induced acute brain injury with standard brain-targeted intensive care.

Published: December 2019

Kebakaran hutan merupakan permasalahan yang hampir setiap tahun terjadi di Indonesia terutama di pulau Sumatera dan Kalimantan. Umumnya kejadian kebakaran hutan di Indonesia terjadi pada lahan gambut, hal ini dikarenakan pada musim kemarau, lahan gambut akan menjadi sangat kering sampai kedalaman tertentu sehingga akan mudah terbakar. Upaya menanggulangi kebakaran hutan telah dilakukan melalui pemantauan titik api melalui satelit, hal ini telah dilakukan oleh NASA (National Aeronautics and Space Administration) dengan satelit Terra dan Aqua melalui instrument MODIS (Moderate Resolution Imaging Spectroradiometer). Data yang didapatkan dari satelit tersebut mulai dari tahun 2001 sampai dengan 2018 kemudian diproses menjadi jumlah kejadian titik api perbulan yang selanjutnya dianalisa dengan pendekatan deret waktu menggunakan model Seasonal ARIMA (Auto Regressive Integrated Moving Average). Hal ini dilakukan untuk mengetahui korelasi jumlah kejadian titik api yang terjadi dengan jumlah kejadian titik api pada waktu sebelumnya. Hasil pengujian menunjukkan bahwa model ARIMA (1,0,1)x(1,0,1,12) adalah model terbaik untuk melakukan prediksi jumlah titik api dengan nilai RMSE sebesar 5.85.

To read current and load, the current sensor (ZHT 03) and voltage sensor (ZMPT101B) are used. All sensor and relay data is performed by Arduino Nano. Whereas NodeMCU 12-E is used to connect the Smart Plug with the web and database. Smart Plug test results with the web site show that Smart Plug can work well on protection and control systems. This is evidenced by the interrupted current flowing at the load, the load compilation current is more than the value of the current that has been determined as the set point. While the control system can also work optimally. Relays can be received according to orders given from the website.

Aim: The interaction between cigarette smoking and efficacy of platelet function testing is not definitely shown. We aimed to conduct the effects of smoking on platelet reactivity by P2Y12 platelet function testing on the patients treated with clopidogrel.
Materials and Methods: This prospective study contained 200 patients who underwent a previous stent implantation. Diagnostic coronary angiography was performed those patients due to chest pain. The clopidogrel resistance test was applied. Furthermore, the smoking effect on platelet reactivity was investigated.
Results: We found that 17% of the patients (34/200) clopidogrel-resistant by P2Y12 platelet function test. We didn’t find any relationship between angiographic stent restenosis and clopidogrel resistance (p>0.05). There was statistically significant relationship between smoking and clopidogrel resistance. The smokers had also higher platelet reactivity level (>208 PRUs) as revealed by VerifyNow P2Y12 assay.
Conclusion: The test results achieved through the clopidogrel resistance by P2Y12 platelet function testing did not meet expectation with the angiographically observations. Therefore, P2Y12 platelet function testing can be unclear in smoker patients.
