Abstract:
ABSTRACT Primary transcripts encoding the MADS box superfamily of proteins, such as MEF2 in animals and ZEMa in plants, are alternatively spliced, producing several isoformic species. We show here that murine serum response factor (SRF) primary RNA transcripts are alternatively spliced at the fifth exon, deleting approximately one-third of the C-terminal activation domain. Among the different muscle types examined, visceral smooth muscles have a very low ratio of SRFΔ5 to SRF. Increased levels of SRFΔ5 correlates well with reduced smooth muscle contractile gene activity within the elastic aortic arch, suggesting important biological roles for differential expression of SRFΔ5 variant relative to wild-type SRF. SRFΔ5 forms DNA binding-competent homodimers and heterodimers. SRFΔ5 acts as a naturally occurring dominant negative regulatory mutant that blocks SRF-dependent skeletal α-actin, cardiac α-actin, smooth α-actin, SM22α, and SRF promoter-luciferase reporter activities. Expression of SRFΔ5 interferes with differentiation of myogenic C2C12 cells and the appearance of skeletal α-actin and myogenin mRNAs. SRFΔ5 repressed the serum-induced activity of the c-fos serum response element. SRFΔ5 fused to the yeast Gal4 DNA binding domain displayed low transcriptional activity, which was complemented by overexpression of the coactivator ATF6. These results indicate that the absence of exon 5 might be bypassed through recruitment of transcription factors that interact with extra-exon 5 regions in the transcriptional activating domain. The novel alternatively spliced isoform of SRF, SRFΔ5, may play an important regulatory role in modulating SRF-dependent gene expression.

Abstract:
Transportation technology using electric energy is growing. Electric cars are increasingly being used to reduce fuel oil usage. In addition to the increasingly sophisticated performance of electric cars, the vehicle safety system must also be improved. The existence of Artificial Intelligence is one of the developments in technological sophistication in a world that is increasingly unstoppable and unavoidable. One of the most popular luxury cars in Indonesia, one of which is the Tesla, which is a sophisticated car with the support of an artificial intelligence system, making Tesla an electric car with an automatic control vehicle feature that can run without using a human driver and can provide safety protection for the driver by using automatic braking system in case of an unexpected accident. This journal proposes a future concept design for the forerunner of automatic braking for electric cars using the ATMEGA 8535 microcontroller as the main automatic control and ultrasonic distance sensor. The PWM signal from the microcontroller is used to adjust the speed of the DC motor as the main driving force of the vehicle. The display of the distance between the vehicle and the obstacle can be seen on the LCD and the buzzer is used as an indicator of the safe distance of the car. The experiment was carried out using an RC car with the area to be protected> 500cm (5m), if the SRF05 ultrasonic sensor detects an obstacle at that distance, the SRF05 ultrasonic sensor will send a signal to the microcontroller and turn on an alarm in the form of a buzzer so that the SRF05 ultrasonic sensor will stop signal propagation.

Abstract:
Abstract Internet of Things (IoT) using LoRa technology has been widely used in many fields. One of them is in disaster mitigation and management. This paper presents sensor nodes as part of a Flood Early Warning System using LoRa technology. The node consists of a water level sensor and a water flow meter. Water level measurements were carried out by ultrasonic sensors HY-SRF05, and the speed of water flow is measured by water flow meter YF-S201. Communication between the nodes and the gateway is done by the BsFrance Lora32u4 II v1.4 Wireless Transceiver module. Data regarding the height of the water level and speed of water flow will be measured by the sensor and sent by the LoRa device to the gateway. The gateway then forwards that data to an open-source IoT platform for analysis and visualization. Testing ultrasonic sensor readings get an accuracy of 97.06%. Waterflow sensor testing obtained 91.96% accuracy. In addition to testing the measurement accuracy, data transmission consistency is also tested against the distance between the gateway and the node. The test results show that the data can still be sent at a space between the node and the gateway below 400 m. Above 400m, the data cannot be received by the gateway anymore. Testing delay time between reading data and receiving data on the IoT platform shows the average delivery delay of 0 ms.

Abstract:
In mammals, different forms of stress, including psychosocial stress, can affect various aspects of human health, promoting mood and anxiety disorders. However, very little is known about the mechanisms underlying the brain physiology of stress response, hindering the development of new therapeutic strategies. We uncover a role for the transcriptional corepressor Lysine Specific Demethylase-1 (LSD1) and its dominant negative splicing isoform neuroLSD1, in the modulation of emotional behavior. In the mouse hippocampus, LSD1 and neuroLSD1 interacting with the transcription factor Serum Response Factor (SRF) and SRFΔ5 participate as molecular transducers of stress stimuli. Likewise LSD1, also SRF is modulated by an alternative splicing isoform without transactivation domain, SRFΔ5. Psychosocial stress acutely reduces the expression of neuroLSD1 through a splicing-based modulation that results in an increase in the amount of LSD1, while the relative ratio between SRF and SRFΔ5 is sensitive both to ASDS and CSDS. Furthermore, SRFΔ5 shows SUS-restricted downregulation that might contribute to shaping psychosocial stress vulnerability, through interfering with homeostatic mechanisms underlying stress resiliency. All these data suggest the involvement of the dual LSD1/neuroLSD1 and SRF/SRFΔ5 in the adaptive response to stress. Alternative splicing is a strategic biological mechanism that allows to create a set of functionally different gene products from a single gene, diversifying gene functions without an increase in the number of genes. neuroLSD1, an activity-dependent splicing isoform that differs from LSD1 for the inclusion of exon 8a, was related to important homeostatic neuronal functions impacting emotional processing. It has recently been published that MALAT1(metastasis associated lung adenocarcinoma transcript 1), a long non-coding RNA, has a crucial role in the alternative splicing mechanism of some genes through the regulation of the splicing factor SRSF1, belonging to the SR protein family. In particular MALAT1 is mainly localized at the level of the nuclear speckles, where it seems to regulate the alternative splicing through the retention of SRSF1 in these nuclear domains and the modulation of their phosphorylation state through an unknown mechanism. We already published that alternative splicing involving LSD1 is positively regulated in trans by two splicing factors NOVA1 and nSR100. In particular, nSR100 is a splicing factor belonging to the SR protein family, as SRSF1, and regulates tissue-specific alternative splicing in a manner dependent on its concentration and its phosphorylation status. We propose MALAT1 as a negative modulator of the neurospecific splicing of LSD1, in particular following ASDS the increased levels of MALAT1 lead to the sequestration of nSR100 at the level of nuclear speckles, making clear the mechanism behind the decrease of the dominant negative neuroLSD1 expression levels following stress We found that following a chronic psychosocial stress the expression levels of MALAT1 seem to be positively regulated only in resilient individuals who manage to maintain physiological expression levels of IEG in the hippocampus. Our hypothesis is that only resilient subjects are still able to modulate maladaptive stress-related transcription, thanks to the increased levels of MALAT1, bringing the system back to basal physiological conditions through the negative regulation of neuroLSD1 formation. All this suggests that MALAT1 could be considered a possible hallmark of resilience.

Abstract:
This master's thesis deals with determination of properties of the ultrasonic sensor SRF05. It is about finding factors that distort or have other negative effects in any way on the proper functionality of these sensors. First of all, it was necessary to program a chip mounted on signal processing board for correct functionality and operation of sensors. Then a few sets of measurements were done to determine the behaviour of sensors for different distances. In addition, we had to carry out many more measurements to find out the influence of temperature, light conditions, material of the sensed surface or cross-noise caused by the use of multiple sensors. In the next step, the approximate shape of the transmitted ultrasound was investigated to determine the zone of detection. The last task of this thesis was to compare the SRF05 sensors with other ultrasonic sensors from different manufacturers.
