While the results of many mangrove rehabilitation efforts have not been optimal due to various factors, the rate of mangrove forest deforestation remains high in Indonesia. This research was designed to test the principle “planting certain mangrove seedlings on suitable habitat would be survived”. The test was based on an assessment of six locations in Bolaang Mongondow Selatan Regency where mangrove rehabilitation programs were implemented. This assessment was conducted by using a spot check method to analyze any variables associated with plantation area feasibility, and the use of a participative approach to collect additional information. Results from this study confirmed that mangrove seedlings have to be planted on the right habitat and that the implemented rehabilitation programs have followed a try and error or speculative approach, and have not been supported by sufficient technical and theoretical competencies. Keywords: artificial plantation, natural regeneration, mangrove, rehabilitation        Deforestasi hutan mangrove di Indonesia berlangsung cepat, sementara itu banyak upaya rehabilitasi belum memberikan hasil yang optimal karena berbagai faktor. Penelitian ini menguji secara khusus prinsip “benih yang ditanam di tempat yang cocok akan tumbuh”, melalui penilaian enam lokasi program rehabilitasi mangrove di Kabupaten Bolaang Mongondow Selatan. Penilaian dilakukan menggunakan metode pengecekan lapangan (on spot check) untuk menganalisis variabel-variabel yang berkaitan dengan kelayakan lahan tanam, dan pengumpulan informasi melalui pendekatan partisipatif. Hasil penelitian menegaskan bahwa “jenis bibit yang ditanam harus sesuai dengan lahan tanam”. Upaya penanaman yang dilakukan masih menggunakan pendekatan coba-coba atau spekulatif, dan tidak didukung pemahaman teknis maupun teoritis yang memadai.Kata kunci: mangrove, penanaman artifisial, regenerasi alami, rehabilitasi

Abstract The identification of the right order of the equation in applied fractional modeling plays an important role. In this paper we consider an inverse problem for determining the order of time fractional derivative in a subdiffusion equation with an arbitrary second order elliptic differential operator. We prove that the additional information about the solution at a fixed time instant at a monitoring location, as “the observation data”, identifies uniquely the order of the fractional derivative.

Dopamine receptors include the D1- (D1 and D5 subtypes) and D2-like (D2, D3, and D4 subtypes) families. D1-like receptors are positively and D2-like receptors negatively coupled to the adenylyl cyclase. Dopamine D2-like (D4 subtype) receptors have been identified in human and rat hearts. However the presence of D2 and D3 receptor subtypes is unclear. Furthermore, their role in cardiac functions is unknown. By autoradiographic studies of guinea pig hearts, we identified D3 and D4 receptors, using the selective radioligands [3H]-7-OH-DPAT and [3H]emonapride (YM-09151-2 plus raclopride). Western blot analysis confirmed D3 and D4 receptors in the right and left ventricle of the same species. Selective agonists of D3 and D4 receptors (±)-7-OH-DPAT and PD 168 077 (10–9 to 10–5 M, respectively) induced a significant negative chronotropic and inotropic effect in the isolated guinea pig heart preparation. Negative inotropic effect induced by PD 168 077 was associated with an inhibition in cyclase activity. No changes in cyclase activity were found with (±)-7-OH-DPAT. The aim of this study is to support the presence of D3 and D4 receptors in the heart. Although our results suggest that D3 and D4 receptors are functionally active in the heart, we need additional information with an antagonist and an agonist of improved potency and selectivity to understand the respective roles of D3 and D4 receptors in the cardiac functions.Key words: Dopamine receptors (D2, D3, D4 subtypes), autoradiography, Western blot, cAMP, heart.

The so-called Brugada syndrome (BS), first called precordial early repolarization syndrome (PERS), is characterized by the association of a fascinating electrocardiographic pattern, namely an aspect resembling right bundle branch block with a coved and sometime upsloping ST segment elevation in the precordial leads, and major ventricular arrhythmic events that could rarely lead to sudden death. Its electrogenesis has been related to a conduction delay mostly, but not only, located on the right ventricular outflow tract (RVOT), probably due to a progressive fibrosis of the conduction system. Many tests have been proposed to identify people at risk of sudden death and, among all, ajmaline challenge, thanks to its ability to enhance latent conduction defects, became so popular, even if its role is still controversial as it is neither specific nor sensitive enough to guide further invasive investigations and managements. Interestingly, a type 1 pattern has also been induced in many other cardiac diseases or systemic diseases with a cardiac involvement, such as long QT syndrome (LQTS), arrhythmogenic right ventricular cardiomyopathy (ARVC), hypertrophic cardiomyopathy (HCM) and myotonic dystrophy, without any clear arrhythmic risk profile. Evidence-based studies clearly showed that a positive ajmaline test does not provide any additional information on the risk stratification for major ventricular arrhythmic events on asymptomatic individuals with a non-diagnostic Brugada ECG pattern.

Background Implant-based dual-plane augmentation mammoplasty requires accurate separation of the pectoralis major muscle (PMM) at its origins. The authors identified the PMM origins during breast reconstruction surgery with the goal of providing additional information on subpectoral implant insertion for reconstructive or aesthetic purposes.Methods This study was conducted on 67 patients who underwent breast reconstruction surgery at the breast center of our hospital between November 2016 and June 2018. In total, 34 left and 39 right hemithoraces were examined. The left and right hemithoraces were each divided into 15 zones to determine the percentage of PMM attachments in each zone. The distribution of PMM origins in each zone was examined to identify any statistically significant differences.Results There were no statistically significant differences in the origins of the PMM between the right and left hemithoraces. The percentage of attachments increased moving from the fourth to the sixth rib and from the lateral to the medial aspect.Conclusions The anatomical findings of this study could be used as a reference for accurate dissection of the origins of the PMM for the preparation of the subpectoral pocket for subpectoral implant placement.

Ornamental fish trade between regions in Indonesia allows the transfer of disease, especially if the disease does not show clinical symptoms in fish traded. Koi fish in Tahuna, North Sulawesi, mostly come from the area of ​​East Java, which is one area with many cases of myxobolusis. In addition, the potential for parasitic diseases that come along when koi fish are brought between areas cannot be avoided, because the examination of parasites, especially Myxobolus sp. no longer listed in the regulation as a quarantine inspection requirement. The purpose of this study was to see the Myxobolus sp infestation that infected koi in Tahuna, North Sulawesi, although there were no clinical symptoms using conventional techniques and histopathology. The results of the examination showed Myxobolus spore infestation on the gills of the koi, although the amount was not much, both conventional and histopathological techniques. This shows that our level of awareness of the types of parasites that can infect fish is still lacking. Myxobolus sp is only transmitted through the spore stage back and forth; there is no horizontal or vertical transmission in fish or tubifex T worm populations. More knowledge regarding the life cycle of the Myxobolus sp. in order to obtain the right handling to deal with outbreaks, especially water quality management at the location of the cultivation.

Abstract Recent theories suggest that self-consciousness, in its most elementary form, is functionally disconnected from the phenomenal body. Patients with psychosis frequently misattribute their thoughts and actions to external sources; and in certain out-of-body experiences, lucid states, and dreams body-ownership is absent but self-identification is preserved. To explain these unusual experiences, we hypothesized that self-identification depends on inferring self-location at the right angular gyrus (i.e., perspective-taking). This process relates to the discrimination of self-produced signals (endogenous attention) from environmental stimulation (exogenous attention). Therefore, when this mechanism fails, this causes altered sensations and perceptions. We combined a Full-body Illusion paradigm with brain stimulation (HD-tDCS) and found a clear causal association between right angular gyrus activation and alterations in self-location (perspective-taking). Anodal versus sham HD-tDCS resulted in: a more profound out-of-body shift (with reduced sense of agency); and a weakened ability to discriminate self from other perspectives. We conclude that self-identification is mediated in the brain by inferring self-location (i.e., perspective-taking). Self-identification can be decoupled from the bodily self, explaining phenomena associated with disembodiment. These findings present novel insights into the relationship between mind and body, and may offer important future directions for treating psychosis symptoms and rehabilitation programs to aid in the recovery from a nervous system injury. The brain’s ability to locate itself might be the key mechanism for self-identification and distinguishing self from other signals (i.e., perspective-taking).

The Shamakhi-Ismailli seismogenic zone is known as the zone of the most powerful earthquakes in the Caucasus, which has been characterized by high seismic activity for centuries. Analysis of seismicity over the past 15 years has shown an increase in activity in this region. In October 2012, there was a devastating earthquake with a magnitude of 5.3. It is this earthquake that can be considered a trigger of activity in this region in subsequent years. In view of this, the task of studying seismicity, as well as the stress fields of the lithosphere of the region under study, seems to be especially urgent. The study of the seismicity of the Shamakhi-Ismailli zone provides additional information on the deep tectonic processes occurring in this region, which is important for seismic zoning. Aim. The article analyzes the seismic activity of the Shamakhi-Ismailli region, which began with an earthquake on February 5 at 19 h 19 min, with ml = 4.4, which occurred 11 minutes before the main shock with an intensity of 6 points, which occurred on February 5, 2019 at 19 h 31 m. Methods.The epicentral field was studied, as well as the distribution of foci in depth, solutions of the mechanisms of foci of the main shock and the most noticeable aftershock were constructed and analyzed. A diagram of the main elements of the rupture tectonics of the Shamakhi-Ismailli focal zone has been drawn, on which the mechanisms of the focal points of the lakes of the Ismailli field are plotted. Results. It has been established that the source area is located in the zone of intersection of the Vandam longitudinal fault with the West Caspian and transverse Akhsu strike-slip faults, which additionally characterizes the high seismic activity and deep penetration of the West Caspian right-sided orthogonal fault. Thus, it can be seen that, in terms of epicenters, they tend to the basement faults and the nodes of their intersection, i.e. The main shock that occurred on February 5, 2019, shows the agreement of the second nodal plane NP2 with the right-lateral Akhsu and West-Caspian transverse faults characterized by the type of displacement right-lateral strike-slip. An analysis of the orientation of the compression axes showed the NE-SW orientation, and the extension axes of the NW-SE orientation Шамахи-Исмаиллинская сейсмогенная зона известна как зона самых сильных землетрясений на Кавказе, которая на протяжении веков характеризовалась высокой сейсмической активностью. Анализ сейсмичности за последние 15 лет показал рост активности в этом регионе. В октябре 2012 года произошло разрушительное землетрясение магнитудой 5,3. Именно это землетрясение можно считать триггером активности в этом регионе в последующие годы. В связи с этим задача изучения сейсмичности, а также полей напряжений литосферы изучаемого региона представляется особенно актуальной. Изучение сейсмичности Шамахи-Исмаиллинской зоны дает дополнительную информацию о глубинных тектонических процессах, происходящих в этом регионе, что важно для сейсмического районирования. Цель работы.В статье проанализирована сейсмическая активность Шамахы-Исмаиллинского района, начавшаяся землетрясением 5 февраля в 19 ч 19 мин, с ml = 4,4, произошедшим за 11 минут до главного толчка с интенсивностью 6 баллов, произошедшего 5 февраля 2019 в 19 час 31 мин. Методы работы. Изучены эпицентральное поле, распределение очагов по глубине, построены и проанализированы решения механизмов очагов главного толчка и наиболее заметного афтершока. Составлена схема основных элементов разрывной тектоники Шамахы-Исмаиллинской очаговой зоны, на которой нанесены механизмы очагов озер Исмаиллинского месторождения. Результаты работы. Установлено, что очаговая область расположена в зоне пересечения Вандамского продольного разлома с Западно-Каспийским и поперечным Ахсуйским сдвигами, что дополнительно характеризует высокую сейсмическую активность и глубокое проникновение Западно-Каспийского правостороннего ортогонального разлома. Таким образом, видно, что в плане эпицентров они стремятся к разломам фундамента и узлам их пересечения, т.е. главный толчок, произошедший 5 февраля 2019 г., показывает совпадение второй узловой плоскости NP2 с правосторонним Ахсуйским и Западно-Каспийским поперечным разломом, характеризующимися правосторонним сдвиговым типом смещения. Анализ ориентации осей сжатия показал ориентацию СВ-ЮЗ, а оси растяжения – ориентацию СЗ-ЮВ.

Abstract: During the developmental stage, children begin to do a variety of activities including tooth brushing. Generally, children use their right hands dominantly to do their activities (right-handed), however, there are also children who use their left hands (left-handed) dominantly. This study was aimed to assess the oral hygiene status based on tooth brushing with a combination technique among left-handed and right-handed children. This was a descriptive study with a cross-sectional design. Population study consisted of left-handed and right-handed children at Kalawat, North Minahasa, North Sulawesi province. Respondents were 60 children consisted of 30 left-handed children and 30 right-handed children obtained by using the purposive sampling method. Data were obtained by using checking form of oral hygiene status. The results showed that oral hygiene status of most left-handed and right-handed children was in good category. The average of OHI-S score of the left-handed children before tooth brushing was 0.7 and after tooth brushing was 0.3, whereas, of the right-handed children, the average of OHI-S score before tooth brushing was 0.6 and after tooth brushing was 0.2. Conclusion: Oral hygiene status of right-handed children who brushed their teeth with a combination technique was better than of the left-handed children.
