Primary squamous cell carcinoma of the stomach presenting as a huge retroperitoneal tumor: a case report

A man complained of upper abdominal pain and early satiety for one month. An upper gastrointestinal endoscopy showed nothing special. A CT scan of the abdomen was performed, which demonstrated a huge heterogeneous retroperitoneal mass close to the dorsal wall of the stomach and surrounding the abdominal aortic and celiac trunk. The resected specimen suggested that an irregular tumor invaded the dorsal wall of the stomach. Postoperative histological examination confirmed that it was a gastric squamous cell carcinoma.

Expression of Oct-4 in oncogenic miR-155-positive oral squamous carcinoma cells

Purpose: To identify effective molecular diagnostic methods for oral squamous cell carcinoma (OSCC) to facilitate treatment of the disease in its initial stages. Methods: To identify molecular markers, OSCC tissue samples were collected from cancer patients and healthy controls. CD44+ cells were sorted using quantitative real-time polymerase chain reaction (qRT-PCR). Immunohistochemistry and immunostaining experiments were performed to identify markers for OSCC. Results: The qRT-PCR data confirmed the presence of oncogenic miR-155 in the OSCC samples. The immunohistochemical and immunostaining results confirmed the expression of Oct-4, an important target for the early diagnosis of OSCC, in oncogenic miR-155-positive OSCCs. Conclusion: Detection of the expression of miR-155 and Oct-4, which are key molecular markers, may be useful in improving the early diagnosis of OSCC.

Lady Nugent and Tom Cringle on the veranda : early nineteenth century observations on a Caribbean architectural feature

This study of the veranda as seen through the eyes of Lady Maria Nugent and Michael Scott, alias Tom Cringle, clearly demonstrates the important role that the piazza, as it was then more commonly known, played in the life of early nineteenth century Caribbean colonial society. The popularity of the veranda throughout the region, in places influenced by different European as well as African cultures, and among all classes of people, suggests that the appeal of this typical feature was based on something more than architectural fashion. A place of relative comfort in hot weather, the veranda is also a space at the interface of indoors and outdoors which allows for a wide variety of uses, for solitary or small or large group activities, many of which were noted by Nugent and Scott. Quintessentially, the veranda is a place in which to relax and take pleasure, not least of which is the enjoyment of the prospect, be it a panoramic view, a peaceful garden or a lively street scene. Despite the great changes in the nature of society, in the Caribbean and in many other parts of the world, the veranda and related structures such as the balcony continue to play at least as important a role in daily life as they did two centuries ago. The veranda of today’s Californian or Australian bungalow, and the balcony of the apartment block in the residential area of the modern city are among the contemporary equivalents of the lower and upper piazzas of Lady Nugent’s and Tom Cringle’s day.
