Although a common site of metastases, primary fallopian tube carcinoma comprises only 0.3% of all gynaecological malignancies. Presenting symptoms are variable and non-specific, with preoperative diagnosis rarely entertained. The FIGO system assigns nearly two-thirds of patients to stage I or II and is based on surgical staging criteria similar to those for ovarian cancer. Likewise, management ...

IMPORTANCE Identifying high-risk patients in the preoperative period can allow physicians to optimize nutritional status early for better outcomes after head and neck cancer resections. OBJECTIVE To develop a model to predict preoperatively the need for gastrostomy tube (G-tube) placement in patients undergoing surgery of the upper aerodigestive tract. DESIGN, SETTING, AND PARTICIPANTS This...

Ovarian cancer has a disproportionately high mortality rate because patients typically present with late-stage metastatic disease. The vast majority of these deaths are from high-grade serous carcinoma. Recent studies indicate that many of these tumors arise from the fallopian tube and subsequently metastasize to the ovary. This may explain why such tumors have not been detected at early stage ...

Objective: Decannulation of patients with tracheotomy usually requires decrease in tracheostomy tube size, capping for 24-48 hours and observation after tube removal. Delay in decannulation may increase cardiopulmonary load, prolong hospitalization and cause patient distress. We propose a one-stage procedure in an intensive care unit (ICU) setting for patients undergoing head and neck surgeries...

A new monoclonal antibody, MEBL-1, which specifically recognizes melanocytes and their precursors, was used to examine the differentiation of neural crest cells into melanocytes in situ. MEBL-1-positive precursors of melanocytes in the trunk were first detected in mesenchyme located above the neural tube at the level of a wing bud at stage 19, when active migration of neural crest cells along t...

Fate-map studies have provided important information in relation to the regional topology of brain areas in different vertebrate species. Moreover, these studies have demonstrated that the distribution of presumptive territories in neural plate and neural tube are highly conserved in vertebrates. The aim of this review is to re-examine and correlate the distribution of presumptive neuroepitheli...

OBJECTIVE The efficacy of transanal ileus tube in acute obstructive left-sided colorectal cancer was discussed. METHOD A total of 101 cases of acute obstructive left-sided colorectal cancer were divided into two treatment groups. For the experimental group consisting of 52 cases, decompression was performed using transanal ileus tube along with drainage and flushing as preparations for one-st...

To thrive in an ever-changing environment, microbes must widely distribute their progeny to colonize new territory. Simultaneously, they must evolve and adapt to the stresses of unpredictable surroundings. In both of these regards, diversity is key-if an entire population moved together or responded to the environment in the same way, it could easily go extinct. Here, we show that the epigeneti...

1. Abstract The aim of this paper is to determine the optimal design and operation of an activated sludge system that is being installed in a small town in the north of Portugal. This process design takes into consideration real data in order to define the objective cost function which includes both investment and operation costs. The collected data were also used to characterize the wastewater...
