AI Article Synopsis
- Developed a quick and efficient method for identifying Cuscutae Semen and Raphani Semen using rapid PCR amplification.
- Samples were collected, DNA was extracted, and the ITS sequences were amplified, sequenced, and analyzed for authenticity.
- Results showed that the method effectively distinguishes genuine samples from adulterants based on fluorescence under UV light, supporting the authentication of traditional Chinese medicinal materials.
Article Abstract
To establish an accurate, rapid and efficient method for authenticating Cuscutae Semen and Raphani Semen by using rapid PCR amplification. The samples of Cuscutae Semen, Raphani Semen and their adulterants were collected. The total DNA of the samples has been extracted, and ITS sequence from Cuscutae Semen, Raphani Semen and their adulterants was amplified by PCR and sequenced directionally. These sequences were aligned by using Clustal W. Specific primers were designed and amplified by two-steps PCR amplification method. The rapid PCR methods for authenticating Cuscutae Semen and Raphani Semen were established by optimizing the denatured and annealing temperature, cycle numbers, and etc. When 100 × SYBR Green I was added in the PCR product, strong green fluorescence was visualized under 365 nm UV lamp whereas adulterants showed no florescence. The results indicated that the rapid PCR method can identify Cuscutae Semen and Raphani Semen rapidly. This study provides the technical support for authentication of Chinese medicinal materials.

Drug prediction and treatment using bioinformatics and large-scale modeling have emerged as pivotal research areas. This study proposes a novel multi-level collaboration framework named Syn-COM for feature extraction and data integration of diseases and drugs. The framework aims to explore optimal drug combinations and interactions by integrating molecular virtuality, similarity clustering, overlap area, and network distance.

The dyeing and adulteration of traditional Chinese medicines (TCMs) are continuously updated. Valuable analytical methods for the daily inspection of illegal colorant additives in TCMs and the preparations are in demand. Two deep eutectic solvent (DES)-based vortex-assisted liquid-liquid microextraction (VA-LLME) and ultrasonic-assisted solid-liquid microextraction (UA-SLME) were developed for the sample pretreatment of ten water-soluble colorants and five water-insoluble colorants, respectively, followed by an HPLC-DAD detection.

Background: Cuscutae Semen (CS) has been prescribed in traditional Chinese medicine (TCM) for millennia as an aging inhibitor, an anti-inflammatory agent, a pain reliever, and an aphrodisiac. Its three main forms include crude Cuscutae Semen (CCS), wine-processed CS (WCS), and stir-frying-processed CS (SFCS). Premature ovarian insufficiency (POI) is a globally occurring medical condition.

Objective: Premature ovarian failure (POF), also known as primary ovarian insufficiency, is a major cause of infertility in female worldwide. Excessive apoptosis and impaired autophagy in ovarian granulosa cells are the main pathological mechanisms of POF. The total flavonoids from (TFSC) are often used in the treatment of gynecological endocrine disorders.

Article Synopsis
- Around 30% of the 382 million diabetic patients worldwide suffer from neuropathy, and one-fifth of them develop cognitive impairment (CI), but the causes and treatments are not well understood.
- The study aimed to identify risk factors for CI in type 2 diabetes patients, screen potential therapeutic drugs, and offer insights for prevention and treatment.
- Using data from 719 patients, the researchers found that factors like diabetes duration, age, and certain lab results were significant risks for T2DM-CI, and they identified ten potential drugs, including Metformin, using advanced predictive modeling techniques.
