Gel-Electrophoresis and Diffusion of Ring-Shaped DNA [PDF]

, 1997
A model for the motion of ring-shaped DNA in a gel is introduced and studied by numerical simulations and a mean-field approximation. The ring motion is mediated by finger-shaped loops (hernias) that move in an amoeba-like fashion around the gel obstructions. This constitutes an extension of previous reptation tube treatments.

Crossover from reptation to Rouse dynamics in a one-dimensional model [PDF]

, 2006
A simple one-dimensional model is constructed for polymer motion. It exhibits the crossover from reptation to Rouse dynamics through gradually allowing hernia creation and annihilation. The model is treated by the density matrix technique which permits an accurate finite-size-scaling analysis of the behavior of long polymers.

Laparoscopic Hernia Repair—When Is a Hernia Not a Hernia? [PDF]

JSLS : Journal of the Society of Laparoendoscopic Surgeons, 2013
A wide range of diagnoses can present as inguinal hernia. Laparoscopic techniques are being increasingly used in the repair of inguinal hernias and offer the potential benefit of identifying additional pathology. The authors present the first reported case of a hydrocele of the canal of Nuck diagnosed laparoscopically.

Bleichner’s hernia – lumbar hernia [PDF]

American Journal of Case Reports, 2013
We present a case of a lumbar hernia and a review of the literature of this rare hernia type.The case and the review will discuss the unusual presentations reported, common etiologies, the importance of early operative repair based on the high rate of incarceration and the recent recommendations regarding repair techniques.Lumbar hernias are rare cases,

Acute septic thrombophlebitis of the lower extremities due to foreign body injury and infection: a case report

BMC Infectious Diseases, 2023
Background Septic thrombophlebitis (STP) of the lower extremities caused by foreign bodies is rare in the clinic, and the symptoms are serious. If the correct treatment is not implemented as soon as possible, the patient may progress to sepsis.

Efficacy of prophylactic negative pressure wound therapy after open ventral hernia repair: a systematic review meta-analysis

BMC Surgery, 2023
Introduction The susceptibility to surgical site occurrence (SSO) is high following ventral hernia repair (VHR) surgery. SSO severely increases the physical and mental burden on patients.

Guidelines for treatment of umbilical and epigastric hernias from the European Hernia Society and Americas Hernia Society

British Journal of Surgery, 2020
Umbilical and epigastric hernia repairs are frequently performed surgical procedures with an expected low complication rate. Nevertheless, the optimal method of repair with best short‐ and long‐term outcomes remains debatable.
