Objective: To observe the role of p63 staining in evaluation of morphologically ambiguous lesions of prostate.
Study Design: Descriptive (case series) study.
Place And Duration Of Study: Shaukat Khanum Memorial Cancer Hospital and Research Centre, Lahore, from March to September 2010.
Methodology: p63 immunohistochemistry staining was performed on 30 cases diagnosed as morphologically ambiguous lesions of prostate by histopathologist. Patient's name, age, histology numbers, morphological features, expression of p63 and histopathological diagnosis were recorded and described as frequency percentages.
Results: The prostatic adenocarcinomas were negative for p63 and benign lesions of prostate were positive for p63. Atypical lesions show positive staining in 77.7% and negative staining in 33.3% of cases.
Conclusion: p63 immunohistochemistry staining can be used as a reliable marker to distinguish between benign from malignant morphologically ambiguous lesions of prostate.

In light of the lack of reliable molecular markers for odontogenic myxoma (OM), the detection of copy number variation (CNV) may present a more objective method for assessing ambiguous cases. In this study, we employed multiregional microdissection sequencing to integrate morphological features with genomic profiling. This allowed us to reveal the CNV profiles of OM and compare them with dental papilla (DP), dental follicle (DF), and odontogenic fibroma (OF) tissues.

The motility of macrophages in response to microenvironment stimuli is a hallmark of innate immunity, where macrophages play pro-inflammatory or pro-reparatory roles depending on their activation status during wound healing. Cell size and shape have been informative in defining macrophage subtypes. Studies show pro and anti-inflammatory macrophages exhibit distinct migratory behaviors, in vitro, in 3D and in vivo but this link has not been rigorously studied.

Root nodule symbiosis is traditionally recognized in the Fabales, Fagales, Cucurbitales, and Rosales orders within the Rosid I clade of angiosperms. However, ambiguous root nodule formation has been reported in Zygophyllaceae and Roystonea regia (Arecaceae), although a detailed analysis has yet to be conducted. We aimed to perform morphological analyses of root structures in these plants and utilize metagenomic techniques to identify and characterize the bacterial populations within the nodule-like structures.

The Y-organs (YOs) synthesize and secrete molting hormones, and thus regulate crustacean growth and reproduction. However, the YOs of the orange mud crab Scylla olivacea is yet to be described due to its minute size and ambiguous feature. This study describes the location, morphological characteristics, histology, and the changes of YOs at different molt stages, and examines in vitro ecdysteroid secreted by the YOs of S.
