Cataloging Andy Warhol's Family Album: 1969 - 1974

This thesis project discusses the preservation of acclaimed twentieth century artist Andy Warhol's Family Album. The album is comprised of Polaroid photographs he took and gathered in the early seventies. A highlight of Andy Warhol's use of instant photography, as it pertains to his life and artistic work, is provided to present a concise basis to researchers. It details the steps undertaken to safely house this valuable object to prolong its life, and the cataloging methodology followed to grant access to the album without submitting it to excessive handling wear. It also offers recommendations on the preservation of dye diffusion material such as Polaroid's Polacolor and SX-70 film types.

Streptomerocyanine dyes

Dyes synthesized by condensation of e. g. 4-N,N-dialkylaminobenzaldehydes, 5-N,N-dialkylamino-2-thiophenaldehydes or 5-N,N-dialkylamino-2-furaldehydes, with open chain active methylene compounds have been given the labels merocyanine, neutrocyanine, methine or styryl dyes. All these classifications are misnomers. In terms of systematic nomenclature, their proper classification is as streptomerocyanine dyes. They are used in textile coloration and in dye diffusion thermal transfer printing (D2T2). Furthermore, they have been investigated for their potential as sensitizer dyes in dye sensitized solar cells (DSSC) and for photorefractive applications.

Hemioxonol dyes

Following the classification of hemicyanine dyes Leslie G. S. Brooker suggested the term hemioxonol dye be applied to the case of an oxonol colorant in which one of its terminal unsaturated heterocycles has been replaced by an open chain N(R1)R2 group or saturated heterocyclic ring. For historical reasons, dyes formed from the reaction of 4-N,N-dialkylaminobenzaldehydes or 4-N,N-dialkylaminocinnamaldehydes with a heterocycle containing an active methylene group adjacent to a carbonyl group are often called benzylidene dyes and cinnamylidene dyes, respectively. In terms of systematic nomenclature, their proper classification is as hemioxonol dyes. They are used as filter dyes and antihalation dyes in silver halide photography. Their current main usage is in dye diffusion thermal transfer printing (D2T2).

Anatomical basis of erector spinae plane block: a dissection and histotopographic pilot study

Purpose Erector spinae plane (ESP) block is an interfascial blockade used in different clinical scenarios. This study investigated the ventral extent of dye diffusion in ESP block. Methods The ultrasound-guided ESP block was bilaterally performed with an injection at the T5 vertebral level (21-Gauge, 50 mm needle), using diluted black tissue marking dye (20 mL; 1:4 ratio with standard saline solution) instead of local anesthetic on two fresh-frozen corpses within the body donation program of the University of Padova. Subsequently, the gross anatomical dissection was performed by a combined posterior plus anterior approach, and the histotopographic examination completed. Results Macroscopically by gross anatomical dissection, the dye spreading ranged on the dorsal side of the chest from T2/3 to T10/11 with an extension up to 10 cm laterally, and on the ventral side of the chest from T2/3–T9/10. Microscopically by histotopographic examination, the dye diffused ventrally to the intercostal spaces (2–3 and 5–6 spaces on the right and left, respectively) by following the blood vessels coupled to the dorsal nerve passing through the costotransverse foramen. Conclusions The anterior pathway of dye diffusion from the site of injection within the erector spinae muscle group during an ESP block seems to follow the blood vessels and dorsal rami of spinal nerves, suggesting the passing through the costotransverse foramen to reach the anterior paravertebral space and the intercostal nerves. These findings display an anterior histotopographic diffusion of dye resembling a paravertebral block.
