Are you the perfect surgical assistant?

The theory of catalytically perfect enzymes was first proposed by W.J. Albery and J. R. Knowles in 1976. These enzymes catalyze biochemical reactions at high-speed. Their catalytic efficiency values range from 108-109 M-1s-1. These enzymes are also called 'diffusion-controlled' as the only rate-limiting step in the catalysis is that of the substrate diffusion into the active site. Examples include triose phosphate isomerase, fumarase, and superoxide dismutase.

Robot-assisted natural orifice specimen extraction surgery is a minimally invasive technique that combines robotic precision with natural orifice specimen extraction. A 67-year-old patient successfully underwent the procedure in 290 min, with minimal bleeding and no residual cancer. This approach minimized abdominal trauma, reduced complications, and enabled a quick...

We present our operative approach to robot assisted distal pancreatectomy, splenectomy, and celiac axis resection (DP-CAR), demonstrating that the procedure is safe and feasible with proper planning, patient selection, and surgeon...

A perfectly competitive market is distinguished by several key characteristics, ensuring that no single participant has the power to unilaterally  influence the market price for goods and services.
First, there are a large number of buyers and sellers in the market, none of which are large enough to dictate market conditions. This ensures a high level of competition exists where the price is determined by the overall supply and demand within the market.
Second, the products that are...

In a perfectly competitive market, firms consider three ways to measure revenues: Total Revenue (TR), Marginal Revenue (MR), and Average Revenue (AR).
Total Revenue: Total income from sales, calculated by multiplying the product's selling price by the quantity sold.
Marginal Revenue: The change in total income generated by selling one more unit of the product.
Average Revenue: Revenue earned per unit sold, which is total revenue divided by total units sold. Under perfect competition, AR is...

Monopoly and perfect competition represent two extremes of economic market structures, each with distinct features that impact producers and consumers.
A monopoly exists when a single firm dominates the entire market for a product or service, with no close substitutes. This market dominance gives the monopolist significant control over prices, allowing it to charge higher prices than competitive markets. The key features of monopoly are:
1. Price-setting ability: The monopolist can influence...
