How muscles function--the work loop technique.

The primary function of muscle is to generate force and produce movement in animals. Before 1985, muscle function had typically been examined under maximally stimulated conditions, while held at a constant length or allowed to shorten at a constant force. Although crucial for understanding fundamental mechanisms and properties of muscle, these contractions at a constant length (isometric) or un...

How Insect Flight Steering Muscles Work

Insights into how exactly a fly powers and controls flight have been hindered by the need to unpick the dynamic complexity of the muscles involved. The wingbeats of insects are driven by two antagonistic groups of power muscles and the force is funneled to the wing via a very complex hinge mechanism. The hinge consists of several hardened and articulated cuticle elements called sclerites. This ...

AN EASY SOLUTION FOR THE DIVERTING LOOP COLOSTOMY: OUR TECHNIQUE

 ABSTRACT Background: The loop colostomy is one of the most popular techniques used as a protective maneuver for a distal anastomosis and/or temporary fecal diversion. We are introducing the use of a full thickness skin bridge under the large bowel instead of a glass rod which alleviates problems such as protrusion of the large bowel, retraction of the bowel into the abdomen after removing the ...

How does it work? A generic feedback loop circadian oscillator

Within the past 18 months, common regulatory patterns have emerged among eukaryotic circadian systems — extending from fungi through to mammals. Heterodimeric complexes of PAS-domain-containing transcription factors play positive roles in clock-associated feedback loops, and classic clock proteins like FREQUENCY (FRQ), PERIOD (PER), and TIMELESS (TIM) appear as negative elements. Post-transcrip...

Form follows function: how muscle shape is regulated by work.

What determines the shape, size, and force output of cardiac and skeletal muscle? Chicago architect Louis Sullivan (1856-1924), father of the skyscraper, observed that "form follows function." This is as true for the structural elements of a striated muscle cell as it is for the architectural features of a building. Function is a critical evolutionary determinant, not form. To survive, the anim...
