tausches sind zwar wesentlich kleiner als bei der Phosphorylierung im Licht und den bisher bekannt gewordenen ATP-ase-Reaktionen in Chloroplasten (JAGENDORF und U R I B E 1 5 ) . Die Austauschreaktion verläuft unter ähnlichen Bedingungen wie der lichtinduzierte ATP — Pa-Austausch ( C A R M E L I und A V R O N 8 ) und wie die chemiosmotische Phosphorylierung. Die Induktion der Austauschreaktion ...

The diagnosis line of a surgical pathology report obviously influences therapy and is often critical for proper initiation of same. If the word choice, phrasing, or terminology in the diagnosis is potentially ambiguous or subject to misinterpretation, this could have adverse or sometimes even disastrous consequences. Usually the potential for misinterpretation is a subtle facet of the wording a...

Cross correlation algorithm is the common method for image matching technique. In this paper, an expert system based on cross correlation is designed to reduce the workload of pathologist and improve the screening technology in medical field. The system is proposed to detect, locate and classify between normal and abnormal sperm head by evaluating the similarity between two images. Using cross ...

Providing the best management for patients with bladder cancer relies on close cooperation among uro-oncologists and pathologists. The pathologist is involved in the diagnosis and assessment of prognostic and therapeutic factors in bladder biopsies, transurethral resection (TUR) and cystectomy specimens. The pathologist must report accurately the key features using terms that are well understoo...

CONTEXT The prevalence of brain tumors in the pediatric population differs from that in the adult population. Similarly, the frequency and location of the different histologic types of brain tumors vary significantly between the pediatric and adult populations. OBJECTIVE To familiarize the pathologist with the pediatric brain tumors encountered during intraoperative consultation and with the ...

Differentiation of a melanocytic nevus and melanoma is often a dilemma clinically as well as histologically. This dilemma involves inexperienced as well as knowledgeable pathologists. The provoking question turns out to be: why is this differential diagnosis often a quandary? The answer lies in the fact that there are overlapping cytological and architectural criteria used interchangeably for a...

Epithelial dysplasia (ED) is one of the most important factors in detecting progression an oral tissue alteration towards carcinoma. Its early detection instrumental avoiding tumor. A major difficulty for ED recognized variability pathologist assessments. This study proposes a new method that leverages expertise to design simple and efficient classification system support dysplastic epithelia. ...

Neoadjuvant treatment has become the standard of care for locally advanced gastrointestinal carcinoma, hence, the pathologist increasingly encounters treated primary and metastatic colorectal tumors. The pathologic assessment of therapeutic response and evaluation of residual disease is important because the histologic response to therapy or tumor response grade (TRG) has been shown to correlat...

The traditional clinico-pathologic conference (CPC) begins with a case presentation. Next, a clinician analyzes the clinical information, illustrating the diagnostic process and proposing one “best-fit” diagnosis for the anonymous (and often dead) patient. Finally, a pathologist presents the actual autopsy or histologic findings, either validating or rejecting the clinician’s diagnosis. This “h...
