Villa Della Porta Bozzolo is a villa located at Casalzuigno in the Italian province of Varese. It was donated by the heirs of the Italian senator and pathologist Camillo Bozzolo to the Fondo per l'Ambiente Italiano—the National Trust of Italy—who now manage it
It was built in the 16th century and used as a rural villa and later an aristocratic residence. In the 18th century an impressive Italian garden was added with stairs, fountains, water features and an aedicula decorated with frescoes. Around the villa there are interesting rustic elements, such as a representation of an olive press containing a cycle of rococo frescoes from the workshop of Pietro Antonio Magatti, a painter from Varese.
At the end of the 17th century the villa experienced one of its most important transformations on the initiative of Gian Angelo Della Porta III on the occasion of his marriage to Isabella, daughter of Count Giorgio Giulini. With the assistance of an unknown architect, he set the main axis of the garden parallel to the side of the house—thus contravening the classic rules under which the principal axis must be aligned with the main room of the house, dividing the garden into two symmetrical parts. In 1723, he also built an elaborate fountain, designed by the architect Pellegatta.

A pathologist reviewed these slides and wrote, "The slides are adequately cellular and contain a mixed population of lymphocytes. Most of the lymphocytes are small and mature, although an increased number of lymphoblasts is seen. However, the percentage of lymphoblasts accounts for less than 10% of the lymphocyte population. Occasionally, neutrophils, macrophages, and plasma cells are noted. Diagnosis: Reactive lymph node. Comment: The specific etiology of the reactive lymph node is not apparent, but it is antigenically stimulated consistent with a response to chronic inflammation/infection.

Katy Mallams, forest pathologist with the Southwest Oregon Forest Insect and Disease Service Center. Port Orford cedar technical committee meeting site visit. Battle Axe Port Orford cedar common garden site. BLM Roseburg District, Oregon.
Note: "Long-term common garden out-planting study—Short duration tests in low-stress nursery environments are not well suited for the expression of cumulative response to environmental stresses. Long-term field common garden studies are designed to reveal adaptive-based G-x-E interactions for guiding seed zoning and transfer. Four common garden sites were planted in 1996: Humboldt Nursery in McKinleyville, California, Trinity Lake on the Shasta-Trinity National Forest, and Althouse and Chetco on the Siskiyou National Forest. In 1998, an additional site, Battle Axe, was established on the BLM Roseburg District, which expanded the original 266 families to include samples from the northeast part of the range of Port-Orford-cedar."

On March 24, 2022, WSU Applebaum first-year Pathologists' Assistant students had a training session with Dr. Chester Lowe from Kubtec XPERT Digital Imaging as part of their course Trends in Pathology. They were able to x-ray several pathologic specimens and appreciate anatomical structures that they will experience during their clinical year.

Forest pathologists at the 7th Western Hazard Tree Workshop field trip. Sedona, Arizona.
"Field trip to higher elevation areas toward Flagstaff. Bring your hard hat and appropriate field gear! Tentative Agenda: 1) Deicing salt-caused mortality = hazard tree development along highways/roadways; 2) Travel management rule and hazard tree liability; 3) Why you don't want to live in an aspen grove; and 4) Ski areas and hazard tree issues."

The Wayne State Pathologists’ Assistant program, part of the Eugene Applebaum College of Pharmacy and Health Sciences, recently invited Kubtec Medical Imaging to lecture and train our students on their most recent imaging technology.
Kubtec is a pioneer in 3D breast specimen tomosynthesis for breast cancer treatment, 2D digital x-ray imaging, and augmented intelligence and voice control systems used in the Pathology Laboratory.
Students were able to use our cadaver anatomy organs to look for evidence of pathology and differentiate between healthy and pathologic dissemination in tissue. This was a great hands-on opportunity for students that resulted in a certificate in this state-of-the art technology.
Pathologists have to cut tissue up in order to make slides. The process of cutting up tissue samples an deciding what needs to be looked at under a microscope (and have a slide made) is called "grossing".

The Coolpix 9XX series was perfect for casual photomicrography, because the lens housing braced perfectly against the microscope eyepiece, yielding rock-steady, evenly illuminated handheld images.
Walt Thies (PNW Research, retired) at the 58th Annual Western International Forest Disease Work Conference, held October 4-8, 2010 in Valemount, BC.
From Walt's 2006 Keynote Address:
"In January 1973, I joined Jim Hadfield and Dave Johnson in Portland in the Insect and Diseases Control branch of the Timber Management Division, Region 6. While I was there, we reorganized and moved to State and Private Forestry. In July 1975, I accepted a position as a research plant pathologist with the PNW Research Station’s Corvallis Lab and have been there since."
