The efficacy and safety of an indocyanine green−hyaluronic acid mixture (LuminoMark™) for localization in patients with non-palpable breast lesions: A multicenter, randomized, open-label, parallel phase 3 clinical trial

Frontiers in Oncology, 2023
PurposeThe incidence of early tumor detection is increasing due to popularization of breast cancer screening and the development of imaging techniques.

The discrete energy method in numerical relativity: Towards long-term stability

, 2004
The energy method can be used to identify well-posed initial boundary value problems for quasi-linear, symmetric hyperbolic partial differential equations with maximally dissipative boundary conditions.

Solving Einstein's Equations With Dual Coordinate Frames [PDF]

, 2006
A method is introduced for solving Einstein's equations using two distinct coordinate systems. The coordinate basis vectors associated with one system are used to project out components of the metric and other fields, in analogy with the way fields are ...

Modeling the Black Hole Excision Problem

, 2005
We analyze the excision strategy for simulating black holes. The problem is modeled by the propagation of quasi-linear waves in a 1-dimensional spatial region with timelike outer boundary, spacelike inner boundary and a horizon in between. Proofs of well-

Making serine integrases work for us [PDF]

, 2017
DNA site-specific recombinases are enzymes (often associated with mobile DNA elements) that catalyse breaking and rejoining of DNA strands at specific points, thereby bringing about precise genetic rearrangements.

Base Excision Repair [PDF]

Cold Spring Harbor Perspectives in Biology, 2013
Base excision repair (BER) corrects DNA damage from oxidation, deamination and alkylation. Such base lesions cause little distortion to the DNA helix structure. BER is initiated by a DNA glycosylase that recognizes and removes the damaged base, leaving an abasic site that is further processed by short-patch repair or long-patch repair that largely uses

A bronchogenic cyst, presenting as a retroperitoneal cystic mass

Rare Tumors, 2012
Bronchogenic cysts are mostly benign, congenital abnormalities originating from the remnants of the primitive foregut. A retroperitoneal location is rare.

Mature Teratoma of the Neck: A Case Report [PDF]

Journal of Medical Academics
Background: Teratomas are unusual tumors originating from primordial germ cells that undergo arrest during migration from the hindgut allantois to the gonads in the early weeks of gestational life. These tumors are derived from all three germ cell layers—

SITE-SPECIFIC RECOMBINATION OF THE MYCOBACTERIUM TUBERCULOSISPROPHAGE-LIKE ELEMENT PHIRV1 [PDF]

, 2004
The site-specific recombination systems of bacteriophages and other mobile elements fall into two categories that are named for the integrase protein that catalyzes integration and excision of the phage genome.

Transanal minimally invasive surgery for rectal lesions [PDF]

, 2016
Background and Objectives: Transanal minimally invasive surgery (TAMIS) has emerged as an alternative to transanal endoscopic microsurgery (TEM). The authors report their experience with TAMIS for the treatment of mid and high rectal tumors.
