DNA methylation is one of the earliest discovered forms of gene epigenetic modification. In eukaryotes, methylation occurs only at cytosine, where DNA methyltransferases (DNMTs) convert the 5′ end cytosine of CpG dinucleotides to 5′-methylcytosine. Numerous studies have shown that DNA methylation can induce changes in chromatin structure, DNA conformation, DNA stability, and the interaction patterns … Read more

Recently, RT-Thread engineers completed the BSP adaptation based on the Renesas CPK-RA2L1 development board, supporting drivers for peripherals such as GPIO, UART, I2C, SPI, ADC, DAC, PWM, CAN, on-chip Flash, Watchdog, RTC, etc. With the support of Renesas engineers, the power component (low power LPM) adaptation was completed. Actual measurements show that the chip can … Read more
Meige’s syndrome (also translated as “Meige’s syndrome”) is also known as idiopathic blepharospasm-oromandibular dystonia syndrome. It is a rare type of segmental dystonia, belonging to a form of adult attention deficit hyperactivity disorder, characterized by blepharospasm, difficulty in opening the eyes, with or without involuntary movements of the mouth and mandible. This syndrome manifests as … Read more
In a previous article, we discussed the prediction of CpG islands. Once a CpG island is identified, it is necessary to detect the methylation status of the corresponding region. There are various methods to detect methylation status, but the currently recognized gold standard is the bisulfite sequencing PCR (BSP). BSP Principle Genomic DNA is treated … Read more
Source: GF Securities With the development of intelligent connected vehicles, the number of onboard sensors is increasing, and the improving performance leads to a higher demand for computing power in onboard computing platforms. Compared to lower-level autonomous driving, advanced autonomous driving systems significantly increase the amount of data obtained from sensors, and the effective operation … Read more
Bletilla, also known as Bletilla striata (Thunb.) Reichb.f., is a dried tuber of the orchid plant, widely distributed in various provinces and cities in China, and grows in moist places such as valleys and mountains. Bletilla striata polysaccharide (BSP) is the main active component of Bletilla, which has attracted attention due to its significant effects … Read more
