Cancer-associated fibroblasts (CAFs) exhibit various phenotypes and serve an important role in tumor progression. However, research on podoplanin expression in CAFs is limited, and its role in the cholangiocarcinoma microenvironment remains unclear. The present study analyzed the clinical and pathological records of 42 patients diagnosed with perihilar cholangiocarcinoma (pCCA) in The Affiliate...

foreign body aspiration is unusual in adults, except those who are debilitated or have neuropsychiatric disorders. it can be a life-threatening situation and it often requires a high index of suspicion, because the diagnosis can be obscure. prompt diagnosis and intervention through foreign body retrieval are critical to prevent significant morbidity and mortality. we present a case of denture a...

In the 4-cell Caenorhabditis elegans embryo, two blastomeres are destined to generate pharyngeal cells, each by a distinct developmental strategy: one pathway is inductive, while the other is autonomous. Here, we identify the pha-4 locus. In animals lacking pha-4 activity, an early step in pharyngeal organogenesis is blocked: no pharyngeal primordium is formed and differentiated pharyngeal cell...

OBJECTIVE The aim of this paper was to demonstrate the techiniqes of single-port laparoscopic transperitoneal infrarenal paraaortic lymphadenectomy as part of surgical staging procedure in case of early ovarian cancer and high grade endometrial cancer. METHODS After left upper traction of rectosigmoid, a peritoneal incision was made caudad to inferior mesenteric artery. Rectosigmoid was mobil...

Epithelioid trophoblastic tumor (ETT) is a rare gestational trophoblastic neoplasm of chorionic-type intermediate trophoblasts, and it is most frequently located in the lower uterine segment and endocervix. Due to the epithelial-growth pattern with geographic necrosis exhibited by the neoplastic cells, ETT is commonly confused, both clinically and pathologically, with squamous cell carcinoma. A...

Organ preservation protocols of high-dose chemoradiotherapy have become fairly common to treat head and neck cancers. However, significant swallowing problems can occur. This study examines swallowing, oral tongue pressures, and tongue base-to-pharyngeal wall pressures in a patient who underwent total laryngectomy for improvement of swallowing after chemoradiotherapy for treatment of a hypophar...

Myxoma is the most common primary tumor of the heart. It is uncommon for these tumors to become infected and, at times, clinical presentation is no different from that of an uninfected myxoma. We describe the case of a 58-year-old woman with a previous pharyngeal infection that developed into infection of a left atrial myxoma and which was complicated by systemic embolism affecting the lower li...

In this paper we study the scalar geometries occurring in the dimensional reduction of minimal five-dimensional supergravity to three Euclidean dimensions, and find that these depend on whether one first reduces over space or over time. In both cases the scalar manifold of the reduced theory is described as an eight-dimensional Lie group L (the Iwasawa subgroup of G2(2)) with a left-invariant p...

The pharyngeal muscles of the nasal, oral, and laryngeal pharynxes are required for swallowing. Pharyngeal muscles are preferentially affected in some muscular dystrophies yet spared in others. Muscle stem cells, called satellite cells, may be critical factors in the development of pharyngeal muscle disorders; however, very little is known about pharyngeal satellite cells (PSC) and their role i...
