Abstract:
Encapsulated papillary carcinoma (EPC) is a rare entity among breast malignancies that accounts for < 1- 2 %. Even though they lack distinct myoepithelial layer they are considered as an in-situ carcinomas unless associated with invasive component. Because of overlapping features in benign and malignant conditions, the accurate subcategorization of these lesions is difficult despite of the papillary architecture, commonly leading to misdiagnosis and improper treatment. EPC is a slowly growing tumor with a thick peripheral fibrous capsule and proliferating cell structure with a supporting fi

Abstract:
Invasive papillary carcinomas of breast are rare tumors. They account for approximately 0.5% of all Invasive breast carcinomas. Invasive papillary carcinomas are commonly present in post-menopause women. These tumors lack the myoepithelial cell layer (MCL) within the papillae or at the periphery of the tumor. The diagnosis is difficult due to different clinical and radiological features. Immunohistochemistry (IHC) is really essential to confirming the diagnosis. We are here presenting one index case of a rare variety of invasive papillary carcinoma of the left breast. We present a case of inva

Abstract:
Invasive Papillary Carcinoma(IPC) is an uncommon breast disease, constituting 0.5% to 1% of all breast carcinomas. It is distinguished by the papillary structural design: proliferation characterized by finger-like projections or fronds composed of central fibrovascular cores covered by epithelium, without myoepithelial cell layer. The combination of a residual palpable mass and a frankly bloody aspirate at the fine needle aspiration is a strongest indicator of carcinoma. Clinical and Radiological manifestations of IPC are not specific. Papillary carcinomas may present as bloody nipple discharg

AbstractThe present study investigates the layer-specific mechanical behavior of human skin. Motivated by skin’s histology, a biphasic model is proposed which differentiates between epidermis, papillary and reticular dermis, and hypodermis. Inverse analysis of ex vivo tensile and in vivo suction experiments yields mechanical parameters for each layer and predicts a stiff reticular dermis and successively softer papillary dermis, epidermis and hypodermis. Layer-specific analysis of simulations underlines the dominating role of the reticular dermis in tensile loading. Furthermore, it shows that

In all four groups of heifers, there were fundamental differences in the dynamics of the growth of the thickness of the outer integument.

Tooth eruption is characterized by a coordinated complex cascade of cellular and molecular events that promote tooth movement through the eruptive pathway. During tooth eruption, the stratum intermedium structurally changes to the papillary layer with tooth organ development. We previously reported intercellular adhesion molecule-1 (ICAM-1) expression on the papillary layer, which is the origin of the ICAM-1-positive junctional epithelium. ICAM-1 expression is induced by proinflammatory cytokines, including interleukin-1 and tumor necrosis factor. Inflammatory reactions induce tissue degradati

Glaucoma is a chronic optic neuropathy characterized by irreversible damage to the retinal nerve fiber layer (RNFL), resulting in changes in the visual field (VC). Glaucoma screening is performed through a complete ophthalmological examination, using images of the optic papilla obtained in vivo for the evaluation of glaucomatous characteristics, eye pressure, and visual field. Identifying the glaucomatous papilla is quite important, as optical papillary images are considered the gold standard for tracking.

However, preventing the fertilization process can be useful for many agronomic and plant-breeding purposes, such as seedless fruits or for developing new varieties.
