Objective:To test the hypothesis that glutamate and GABA are linked to the formation of epilepsy networks and the triggering of spontaneous seizures, we examined seizure initiation/propagation characteristics and neurotransmitter levels during epileptogenesis in a translationally relevant rodent model of mesial temporal lobe epilepsy.Methods:The glutamine synthetase (GS) inhibitor methionine sulfoximine was infused into one of the hippocampi in laboratory rats to create a seizure focus. Long-term video-intracranial EEG recordings and brain microdialysis combined with mass spectrometry were used to examine seizure initiation, seizure propagation, and extracellular brain levels of glutamate and GABA.Results:All seizures (n = 78 seizures, n = 3 rats) appeared first in the GS-inhibited hippocampus of all animals, followed by propagation to the contralateral hippocampus. Propagation time decreased significantly from 11.65 seconds early in epileptogenesis (weeks 1-2) to 6.82 seconds late in epileptogenesis (weeks 3 – 4, paired t-test, p = 0.025). Baseline extracellular glutamate levels were 11.6-fold higher in the hippocampus of seizure propagation (7.3 µM) vs. the hippocampus of seizure onset (0.63 µM, ANOVA/Fisher’s LSD, p = 0.01), even though the concentrations of the major glutamate transporter proteins EAAT1, EAAT2 and xCT were unchanged between the brain regions. Finally, extracellular GABA in the seizure focus decreased significantly from baseline several hours before a spontaneous seizure (paired t-test/FDR).Conclusion:The changes in glutamate and GABA suggest novel and potentially important roles of the amino acids in epilepsy network formation and in the initiation and propagation of spontaneous seizures.

Studi memperkirakan emesis gravidarum terjadi pada 50-90% kehamilan. Mual muntah pada kehamilan memberikan dampak yang signifikan bagi tubuh dimana ibu menjadi lemah, pucat dan cairan tubuh berkurang sehingga darah menjadi kental (hemokonsentrasi). Keadaan ini dapat memperlambat peredaran darah dan berakibat pada kurangnya suplay oksigen serta makanan ke jaringan sehingga dapat membahayakan kesehatan ibu dan janin. Salah satu terapi yang aman dan dapat dilakukan untuk mengurangi keluahan mual muntah pada ibu hamil adalah pemberian aromaterapi lemon. Penelitian bertujuan untuk mengetahui efektifitas aroma terapi lemon untuk menangani emesis gravidarum. Penelitian ini menggunakan rancangan Quasi experiment  dengan  one group pre-post test design. Populasi penelitian adalah ibu hamil yang mengalami emesis gravidarum di Kecamatan Berbah, Sleman. Jumlah sampel 20 ibu hamil trimester pertama yang diambil dengan teknik purposive sampling. Pengukuran mual muntah dilakukan debelum dan setelah  pemberian aromaterapi lemon menggunakan Indeks Rhodes. Analisa data menggunakan uji Paired t-test. Hasil penelitian didapatkan rata-rata skor mual muntah sebelum pemberian aromaterapi lemon berdasarkan Indeks Rhodes pada Ibu Hamil dengan emesis gravidarum yaitu 22,1 dan terjadi penurunan skor setelah pemberian aromaterapi lemon menjadi 19,8. Ada pengaruh pemberian aromaterapi lemon dengan pengurangan mual muntah pada ibu hamil (p-value = 0.017). Berdasarkan hasil penelitian dapat disimpulkan pemberian aromaterapi lemon efektif untuk mengurangi emesis gravidarum pada ibu hamil trimester pertama.  Kata kunci: aromaterapi lemon, emesis gravidarum THE EFFECTIVENESS OF LEMON AROMATHERAPY FOR HANDLING EMESIS GRAVIDARUM   ABSTRACT Studies estimate that nausea and vomiting (emesis gravidarum) occur in 50 – 90% of pregnancies. Nausea and vomiting of pregnancy have a significant impact on the body in which it makes a mother becomes weak, pale, and decreasing body fluid so that the blood becomes thick (hemoconcentration). This situation can slow down blood circulation and inflict the lack of oxygen and food supplies to the body tissues so that it can endanger the health of the mother and fetus. One of the therapies that is safe and can be conducted to reduce nausea and vomiting of pregnancy is by giving the lemon aromatherapy treatment. The research aims to determine the effectiveness of the aroma of lemon therapy to deal with emesis gravidarum. This study applied quasi-experimental research with one group pretest-posttest design. The population of this study was pregnant women who experienced emesis gravidarum. Furthermore, samples were 20 mothers from Berbah, Sleman taken by using a purposive sampling technique. Nausea and vomiting were assessed between before and after giving lemon aromatherapy using the Rhodes Index. The data were analyzed using the paired t-test. The mean score of nausea and vomiting before giving lemon aromatherapy on mother with emesis gravidarum based on the Rhodes Index was 22.1. However, it decreased after given lemon aromatherapy treatment to 19.8. Therefore, there was an effect on giving lemon aromatherapy treatment toward the decrease of nausea and vomiting for pregnant women (p-value = 0.017). Lemon aromatherapy is effective to reduce emesis gravidarum.  Keywords: lemon aromatherapy, emesis gravidarum

BACKGROUND Exact quantification of volumetric changes of the extremities is difficult. There are several direct and indirect methods to assess extremity volume. As water displacement volumetry is rarely viable in a clinical setting and circumference measurements are prone to errors due to poor reproducibility and high inter- and intra-observer variability, an objective and easily reproducible method is indispensable. OBJECTIVE The aim of this study was to establish a standardized method based on 3D scans with defined caudal and cranial landmarks of the lower leg which allows for measurements of exactly the same body area. Furthermore, this study tests the method in terms of reproducibility and evaluates volume changes after surgical therapy in patients suffering from lymphedema. METHODS 3D-scans of the lower limb were performed with a mobile 3D-scanner. Volumetric calculation was done digitally. “Repeatability“ and “Inter-observer reliability” of digital volumetry were tested. Furthermore, the method was applied on 31 patients suffering from chronic lymphedema. ANOVA (analyses of variance) was conducted to compare the digital volumetric measurements. To assess the sensitivity to changes in digital volumetry, the mean volume of 31 patients before and 3 months after therapy were compared by a paired t-Test. RESULTS Calculations of repeatability of the volume based on 20 3D-scans of the same lower leg showed a mean volume of 2,488 ± 0,011 liters (range: 2,470 – 2,510). The mean volume of the 7 measurements of the 3 examiners did not differ significantly (F(2,18) = 1,579, p = .233). The paired t-Test showed a significant mean volume decrease of 375ml (95% CI = 245/505ml) between pre and post treatment (t (30) =5,892, p < .001). CONCLUSIONS 3D-Volumetry is a noninvasive, easy and quick method to assess volume changes of the lower leg. Other than the costs, it is reproducible and precise and therefore ideal for evolution of therapy in lymphedema.

Abstract Introduction Thalassemia, as the most common chronic hereditary blood disorder in humans, can impose many adverse effects on parents and their affected children. On the other hand, positive thinking is the method or the result of a positive focus on a constructive issue, so by teaching positive thinking, we can improve physical and social function, and promote emotional health and overall quality of life. The aim of this study was to determine the effect of positive thinking training on the quality of life of parents of adolescents with thalassemia. Methods This quasi-experimental study was performed on 52 parents of adolescents with thalassemia who attended Taleghani Hospital in Golestan province, Iran in 2017. Samples were randomly assigned into two groups of intervention and control. The positive thinking training (based on the theory of Martin Seligman) was carried out in the intervention group in 10 (45–60 min) sessions over a 5-week period. Data collection tools in this study were the World Health Organization (WHO) quality of life questionnaire (WHOQOL-BREF) and a demographic information questionnaire. Data were analyzed by SPSS-16 software using independent t-test, the paired t-test and a covariance test. Results The results of paired t-test showed a significant difference in the score of quality of life in intervention group before and after the intervention (p < 0.001). However, this test did not show any significant difference in the control group (p = 0.11). The covariance test, after removing the pre-test score, showed a significant difference between the intervention and control groups in terms of the score of quality of life, so that 13% of the changes after the intervention were due to the intervention (p = 0.009, η = 0.13). Conclusion The positive thinking training increased the quality of life of parents of adolescents with thalassemia. Therefore, using this program can be an effective way of improving the quality of life of parents. Thus, positive thinking training is suggested to be used as an effective strategy for increasing the quality of life of parents with ill children.
