Field measurements and parametric studies for the thermal environment of underground tunnel entrance in cold climate zones [PDF]

open access: yesE3S Web of Conferences, 2022
In frozen regions, especially metro tunnel portal sections, which are vulnerable to an externally low-temperature atmosphere, would lead to frozen damage affecting traffic safety.

A silver impregnation method for motor and sensory nerves and their endings in formalin-fixed mammalian muscles [PDF]

open access: yes, 1988
A silver impregnation method is described which shows motor and sensory nerves and their endings in formalin-fixed mammalian muscles. The method works with the same reliability on flattened muscle pieces as well as on frozen sections. Large nerve bundles,

Molecular cytogenetic analysis of formalin-fixed, paraffin-embedded solid tumors by comparative genomic hybridization after universal DNA-amplification [PDF]

open access: yes, 1993
We present a technique which allows the detection and chromosomal localization of DNA sequence copy number changes in solid tumor genomes from frozen sections and paraffin embedded, formalin fixed specimens. Based on comparative genomic hybridization and

Optimization of electron microscopy for human brains with long-term fixation and fixed-frozen sections. [PDF]

open access: yes, 2014
BackgroundAbnormal connectivity across brain regions underlies many neurological disorders including multiple sclerosis, schizophrenia and autism, possibly due to atypical axonal organization within white matter.

ULTRATHIN FROZEN SECTIONS [PDF]

open access: yesThe Journal of Cell Biology, 1967
A relatively simple method for obtaining ultrathin, frozen sections for electron microscopy has been developed. Tissues, cultured cells, and bacteria may be employed. They are fixed in 1.25–4% glutaraldehyde for 1–4 hr, are washed overnight in buffer at 3°C, and are embedded in 20% thiolated gelatin or pure gelatin. Before sectioning they are partially

Reliability of intra-operative frozen section study in revision of infected hip arthroplasty

open access: yesArthroplasty, 2019
Introduction Frozen sections are extensively used to help in the diagnosis of periprosthetic joint infection during revision hip arthroplasty, though there are insufficient data in relation to its usefulness. Methods Twenty-one patients with infected hip

The Value of Intraoperative Examination of Axillary Sentinel Nodes in Carcinoma of the Breast. [PDF]

open access: yes, 2008
Axillary sentinel lymph node biopsy (SLNB) has become the standard of care for T1-2, N-0, M-0 carcinoma of the breast. However, the accuracy of frozen section in the intra-operative examination of sentinel nodes (SN) remains controversial.

The frozen nucleon approximation in two-particle two-hole response functions [PDF]

open access: yes, 2017
We present a fast and efficient method to compute the inclusive two-particle two-hole (2p-2h) electroweak responses in the neutrino and electron quasielastic inclusive cross sections. The method is based on two approximations.

Immunocytochemical localization of the main intrinsic polypeptide (MIP) in ultrathin frozen sections of rat lens. [PDF]

open access: yes, 1983
The in situ distribution of the 26-kdalton Main Intrinsic Polypeptide (MIP or MP 26), a putative gap junction protein in ocular lens fibers, was defined at the electron microscope level using indirect immunoferritin labeling of ultrathin frozen sections ...
