Long-patch Base Excision Repair

Long-patch Base Excision Repair

Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Renewal of Skin Epidermal Stem Cells

Renewal of Skin Epidermal Stem Cells

The skin is divided into epidermis, dermis, and hypodermis, the skin's outermost, middle, and inner layers. The human epidermal layer regularly undergoes renewal, where old, dead cells are replaced by new cells. Epidermal stem cells or EpiSCs divide and differentiate to restore the lost cells. For the renewal process, some EpiSCs continuously self-renew. In contrast, few others differentiate into transit-amplifying cells, which later form prickle or spinous cells, followed by granular cells,...

Tissue Renewal without Stem Cells

Tissue Renewal without Stem Cells

After cellular or tissue damage, the resident stem cells present in the human body can locally repair and regenerate the damaged tissue or organ. However, even though some tissues do not have stem cells, they can repair and regenerate with the help of pre-existing cells. For example, beta cells of the pancreas and hepatocytes of the liver can divide to renew and regenerate the tissue. Here, both cell division and cell death are well regulated by homeostasis.
However, failure of such a system...

Skin Cancer

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Healing I: Introduction

Healing I: Introduction

Healing is the physiological process by which the body restores the integrity and function of damaged tissues following injury. It involves a coordinated interplay of cellular proliferation, extracellular matrix remodeling, and growth factor signaling. The extent and nature of the tissue damage determine whether healing occurs by resolution, regeneration, or replacement.ResolutionResolution represents the most complete form of healing, occurring when the injury is minimal and tissue...

Healing II: Complications

Healing II: Complications

Complications during healing arise when tissue repair is altered by local or systemic factors. These changes involve abnormal collagen deposition, altered biomechanics, and reduced vascular supply, impairing restoration of normal structure and function.Loss of FunctionScar tissue differs significantly from the original tissue it replaces. In the skin, fibrosis lacks adnexal structures such as hair follicles, sebaceous glands, and sweat glands. Their absence reduces tactile sensitivity, impairs...

Area of Science:

Orthopedic surgery
Musculoskeletal reconstruction

Background:

Quadriceps tendon ruptures, though rare, can lead to challenging revision repairs due to muscle atrophy and tendon retraction.
Augmentation with allografts or autografts is common in revision repairs to enhance strength and prevent re-rupture.

Purpose of the Study:

To describe a surgical technique for revision quadriceps tendon repair in patients with chronic ruptures.
To evaluate the outcomes of this revision repair procedure.

Main Methods:

The technique involves releasing adhesions, removing prior hardware, and performing a V-Y quadricepsplasty to address tendon retraction.
Tendon advancement is achieved through specific suturing techniques, followed by reattachment to the patella using anchors and Krackow configuration sutures.
Repair is augmented with an Achilles allograft.

Main Results:

Revision quadriceps repair has demonstrated promising functional outcomes.
Patients typically experience a successful return to activities and achieve good to excellent objective results.

Conclusions:

The described V-Y quadricepsplasty technique for revision repair shows favorable outcomes.
Further high-quality research is needed to establish the reliability and efficacy of revision quadriceps repair techniques.
