An N-terminal–truncated isoform of FAM134B (FAM134B-2) regulates starvation-induced hepatic selective ER-phagy
Authors: Kohno Shohei , Shiozaki Yuji , Keenan Audrey L , Miyazaki-Anzai Shinobu , Miyazaki Makoto
Published: May 2019

Autophagy is a conserved system that adapts to nutrient starvation, after which proteins and organelles are degraded to recycle amino acids in response to starvation. Recently, the ER was added to the list of targets of autophagic degradation. Autophagic degradation pathways of bulk ER and the specific proteins sorted through the ER are considered key mechanisms in maintaining ER homeostasis. Four ER-resident proteins (FAM134B, CCPG1, SEC62, and RTN3) have been identified as ER-resident cargo receptors, which contain LC3-interacting regions. In this study, we identified an N-terminal–truncated isoform of FAM134B (FAM134B-2) that contributes to starvation-induced ER-related autophagy. Hepatic FAM134B-2 but not full-length FAM134B (FAM134B-1) is expressed in a fed state. Starvation drastically induces FAM134B-2 but no other ER-resident cargo receptors through transcriptional activation by C/EBPβ. C/EBPβ overexpression increases FAM134B-2 recruitment into autophagosomes and lysosomal degradation. FAM134B-2 regulates lysosomal degradation of ER-retained secretory proteins such as ApoCIII. This study demonstrates that the C/EBPβ-FAM134B-2 axis regulates starvation-induced selective ER-phagy.

Probiotics are defined as live microorganisms which when administered in adequate amounts, confer a health benefit on the host. Nowadays, Probiotics are used for eco-friendly and sustainable production in many production areas. They have also been common organisms that used in aquaculture as growth promoter, stress tolerance, pathogen inhibition, and nutrient digestibility, to increase water quality. Probiotics use in aquaculture comprehensively reviewed as an alternative to antibiotic treatment. However, very few studies have addressed the effects of probiotics on reproductive performance and gamete quality of fish. Thus, this review summarizes most current studies on the effects of probiotics on reproductive performance and gamete quality in fish and evaluates further applications of probiotics in reproduction of fish.

Wireless networks / hostspot using wave or signal transmission media. Waves or signals emitted from a device called an access point having a particular frequency. Signal beam is formed a circular pattern in which the antenna from the access point to the source signal. In a wireless network signal is captured and used a computer to be able to communicate with each other. PING technique is a method to double check the connection by sending data packets from the sending computer to the destination computer. This process can be seen from the travel time required to transmit data packets. So there is some problems how to convert time obtained from the PING into the distance. Algorithm Jawa can be used to convert units of time-based PING the wireless LAN / hostspot into the distance. Basically, two computers that are in a wireless LAN / hostspot will form a triangular pattern. This pattern will be used algorithm jawa to determine the distance between two computers within the wireless LAN / hostspot by utilizing modifications pythagorean theorem for isosceles triangular pattern and the large angle of 400.

The increasing number o f passengers Trans Jogja bus stops can result in the existing capacity can not accommodate the number of passengers comfortably. Problems that often arise include delays resulting bus passenger waiting time is longer and there is a buildup of the number of passengers at stops. As a result of these problems, the capacity o f passenger stops can be full so that prospective passengers waiting outside the bus stop. Forecasting is one very important element in the decision. In this study using stationary and trend forecasting the data because the data are not significant changes between time and swell in certain periods and a normal in periods others. Time series methods for forecasting the number o f passengers on the Trans Jogja stop using exponential smoothing calculation and least square. From these calculations the value sought MAD (Mean Absolute Deviation) or least square error is exponential smoothing and forecasting results with small error. Forecasting will be better if it contains fewer possible errors.

Practicum registration systems that exist on campus STTA previously done manually, where students will sign up to the admin to bring proof of payment practicum. Students are free to choose his own class, this often resulted in unbalanced number of students in the classroom lab that is consideredless  effective way. This makes the emergence of the idea to establish an MM algorithm is applied to a practical application o f automation systems. MM algorithm works by determining many lab classes based on students who took the KRS. Furthermore, students who have paid practicum will be immediately incorporated into the classes that are available with regard to the number of students and GPA o f students per class, so it will obtain practical classes by the number o f students and the average GPA o f each class balanced.Concept application using client-server database, where the database is on the Local Area Network (LAN) STTA. To facilitate the management admin, then the application will be tested on the LAN network and VPN (Virtual Private Network) network. LAN is a computers network that are connected to a computer server by using specific topologies, typically used in areas of the building or area a distance o f not more than 1 km (local area). While VPN is a secure way to access the Local Area Network that is in range, using the Internet or other public network to perform packet data transmission in private. By using a VPN, users can access the computer that is on the LAN even though the user is not in the same location with a LAN.

The increase o f request brings large traffic to networks especially to data centers, large enterprises and portal websites. In addition, server provides more and more information by using applications. Most servers have to provide all-day services, and any service interruption or key data loss in communication will result in business loss. All these require high performance and high reliability on application services. However, the increase of server processing speed and memory access speed is greatly lower than that o f the network bandwidth and applications. In addition, the increase o f network bandwidth makes server resource consumption more serious. Therefore, the servers become the network bottleneck, and the traditional single device mode becomes the network failure point. Load balancing (LB) comes to provide a good solution by providing multiple servers form a server cluster, with each server providing the same or similar services. A load balancing application is managed at the front end o f the server cluster to distribute user requests in the server cluster according to pre-configured load balancing rules, provide services, and maintain the servers. Load balancing bring good advantage such as bring faster application, low cost, the available resources will not be wasted, and no high-end devices are needed for the new resources. It is expandability. When services are increasing, the system can satisfy the needs by adding servers, without affecting the existing services and reducing service quality. Load balancing also has high reliability. When a server fails, the LB application or LB device redistributes user requests to other servers in the same cluster, ensuring uninterrupted services.
