Low Power Application Notes Based on Renesas RA2L1 MCU

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: Understanding Its Mechanisms and Treatment

by

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

Bisulfite Sequencing PCR (BSP) Method

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

Sensory Tricks and Dystonia

by
Sensory Tricks and Dystonia

Dystonia is a movement disorder characterized by involuntary, sustained, or repetitive muscle contractions that cause twisting or abnormal postures of body parts. These conditions are marked by co-contraction of agonist and antagonist muscles, and overflow phenomena, typically categorized into focal, segmental, multifocal, generalized, and hemidystonia. Sensory tricks (sensory trick / geste antagoniste) refer to voluntary … Read more
