Skeletal muscle relaxants have their place in everyday use in numerous anesthesiological procedures, such as preparing a patient for surgery, supporting mechanical ventilation, and performing effective intubation. These drugs can be divided, based on their mechanism of action, into depolarizing skeletal relaxants, such as succinylcholine, and non-depolarizing skeletal muscle relaxants. Non-depolarizing agents are further categorized, based on their structure, into steroidal (eg, rocuronium) and benzylisoquinoline (eg, atracurium) compounds.

Article Synopsis
  • Skeletal muscle relaxants are commonly used in anesthesia for surgeries, mechanical ventilation, and intubation, creating a conduction block at the neuromuscular junction.
  • Reversal agents, like neostigmine and sugammadex, help terminate the neuromuscular blockade and prevent residual effects, but their efficacy can be affected by liver and kidney dysfunction.
  • Liver damage, which can stem from various causes including drug toxicity and metabolic disorders, impairs drug metabolism and can lead to systemic complications, ultimately impacting the use of muscle relaxants in patients with liver disease.

This study included 107 patients with peripheral arterial disease (PAD) undergoing revascularization and aimed to evaluate the effects of body mass index (BMI) on outcomes of quality of life (intermittent claudication questionnaire - ICQ), pain-free walking distance (PFWD), and maximum claudication distance (MCD). The study included 107 patients aged 18-80 years with PAD undergoing revascularization (average age 66±6.7 years; 82% men and 18% women, average BMI 28.

Article Synopsis
  • The working conditions in plastic working operations are influenced by temperature, loads, lubrication, and other factors, especially in sheet metal forming.
  • This article examines the friction behavior of a DC04 steel sheet during a deep drawing process, focusing on the effects of different titanium coatings on tool samples made from cold-work tool steel.
  • Results indicate that coated countersamples maintain a more stable coefficient of friction than uncoated ones, with electron pulse irradiation providing the best stability, while uncoated samples reached the highest temperatures during friction.

Proteolysis-targeting chimeras (PROTACs) have been explored for the degradation of drug targets for more than two decades. However, only a handful of E3 ligase substrate receptors have been efficiently used. Downregulation and mutation of these receptors would reduce the effectiveness of such PROTACs.
