6. Clinical Trial Combining Botulinum Toxin A Injection and Fissurectomy for Chronic Anal Fissure: A Dose-Dependent Study
ABSTRACT Background Anal fissure is a common surgical disease that is usually treated conservatively. The golden surgical treatment for anal fissure is lateral internal sphincterotomy, but it may result in multiple complications. Therefore, other treatment methods have recently been introduced, and one of them is the injection of botulinum toxin A (BTA) and

10. Stability Analyses by HPLC-MS of Guanitoxin Isolated from Sphaerospermopsis torques-reginae
Guanitoxin (GNT) is a natural organophosphate produced by some species of freshwater cyanobacteria, which inhibits the active site of acetylcholinesterase, preventing the hydrolysis of cholinesterases and consequently causing serious disturbances in the neuromuscular system. Despite having a chemical structure like synthetic organophosphates, there is still

12. HYPERSPECTRAL SPECTROSCOPY TO DETECT DIFFERENT RESPONSES OF TWO SOYBEAN (GLYCINE MAX) CULTIVARS TO CHARCOAL ROT (MACROPHOMINA PHASEOLINA) TOXIN
ABSTRACT Previous studies have confirmed the potential of hyperspectral spectroscopy (HS) to detect charcoal rot toxin effect on soybean (Glycine max). However, there is no evidence that it can differentiate among difference responses to that effect. This research tested the potential of HS (900–2400 nm) to differentiate different responses to charcoal rot
