We describe a highly reproducible method for the permanent occlusion of a rodent major cerebral blood vessel. This technique can be accomplished with very little peripheral damage, minimal blood loss, a high rate of long-term survival, and consistent infarct volume commensurate with the human clinical population.

Middle cerebral artery (MCA) ligation is a technique to study focal cerebral ischemia in animal models. In this method, the middle cerebral artery is exposed by craniotomy and ligated by cauterization. This method gives highly reproducible infarct volumes and increased post-operative survival rates compared to other methods available.

In this video, we demonstrate suturing techniques — core suture and Q suture — to repair the foot flexor tendon in an ex vivo porcine model. Q sutures enhance the strength of the core suture in tendon repair and decrease gapping at the tendon repair site.

A protocol for stroke onset time estimation in a rat model of stroke exploiting quantitative magnetic resonance imaging (qMRI) parameters is described. The procedure exploits diffusion MRI for delineation of the acute stroke lesion and quantitative T1 and T2 (qT1 and qT2) relaxation times for timing of stroke.

Permanent Income Hypothesis

The Permanent Income Hypothesis (PIH), formulated by economist Milton Friedman, explains how individuals plan their consumption based on long-term income expectations rather than current earnings. This theory is fundamental for analyzing consumer behavior over time.Friedman separated total income into two parts: permanent income and transitory income.Permanent income represents the average income individuals expect throughout their lives, accounting for predictable and stable...
FAQs
Its continuous tensile strength allows the material to keep wound edges approximated while surrounding tissue heals. Because the suture does not lose its mechanical support through absorption, it can reinforce tissues over extended periods. This sustained support is particularly relevant when healing areas require lasting reinforcement rather than temporary approximation alone.
A permanent suture remains in the body and may provoke a localized foreign-body response. That biological reaction is an important part of evaluating tissue compatibility, because the material must provide lasting mechanical reinforcement while limiting unfavorable effects on healing. Selection therefore considers both structural durability and how the surrounding tissue is likely to tolerate the implant.
Material properties and handling characteristics affect how effectively a permanent suture supports tissue and how suitable it is for a particular repair. Polypropylene, nylon, polyester, and stainless steel are among the materials used. Their characteristics, together with tissue compatibility, can influence healing, infection risk, and long-term surgical outcomes.
Surgeons select permanent suture when tissues require mechanical reinforcement over extended periods. The choice is relevant when wound support must continue as healing progresses, rather than ending after an early phase. This rationale helps explain its use in repairs involving skin, blood vessels, the heart, tendons, fascia, and hernia-related reinforcement.
Common applications include skin closure, vascular and cardiovascular repair, tendon reconstruction, and reinforcement of fascia or hernia repairs. These settings differ in tissue and surgical purpose, but each may require dependable support that persists while healing occurs. The material is therefore used across procedures where long-term wound stability is clinically important.
Evaluation includes the required duration of mechanical support, the material’s properties and handling, and its compatibility with the tissue being repaired. Clinicians also consider potential effects on healing and infection risk because the suture remains present. Matching these factors to the surgical site supports more appropriate material selection and long-term outcomes.
