Metastasis of Rectal Signet Ring Cell Carcinoma to Typical Lipoma: A Rare Presentation of the Tumor-to-Tumor Metastasis Phenomenon.

Rectal signet ring cell carcinoma represents a rare subtype of colorectal adenocarcinoma known for its aggressive biological nature and poor prognosis. Although the co-occurrence of colorectal carcinoma with other tumors has been reported, the uncommon phenomenon of tumor-to-tumor metastasis, first described in 1930, remains rare. The most frequent donor neoplasms are lung or breast carcinomas, whereas cerebral meningiomas have been reported to be the most frequent recipient neoplasms.

Experimental results indicated that greater foam was obtained with camel Na-cas than with bovine Na-cas at all heating temperatures due to the higher β-casein content in camel caseins (~53.4% of total proteins, RP-HPLC results).

Effect of pH and heat treatment on structure, surface characteristics and emulsifying properties of purified camel β-casein.

Oil-in-water emulsions (20%/80%, w/w) were stabilised by two types of β-caseins (1 g/L, w/w) extracted by rennet coagulation from camel and cow's milk, respectively. Both extracts were treated under different ranges of pH (3.0, 6.

Physicochemical, techno-functional, and fat melting properties of spray-dried camel and bovine milk powders.

In this study, three skimmed and one whole-fat spray-dried camel milk powders were produced and their characteristics were compared to those of bovine milk powders. The physicochemical analysis of the produced powders indicated that camel milk powders (whether skimmed or not) presented higher ash and whey protein contents as compared to those of bovine milk powders. Our results indicated that the investigated camel and bovine milk powders exhibited a high solubility index (>99%) with poor dispersibility and wettability indexes due to their small particles size (d ≤ 12 µm) and their narrow size distribution (span ≤ 2).
