OBJECTIVE
To investigate hypoxia tolerance of children with recurrent respiratory papillomatosis with the spread of trachea in surgical procedures without ventilation via endotracheal tube intermittently under general anesthesia.
METHODS
Forty children with recurrent respiratory papillomatosis were
Hypoxia, which occurs frequently in aquatic ecosystems and is mainly due to increasing eutrophication can cause severe environmental stress in fish. We investigated experimentally the hypothesis that hypoxia could be one of the environmental stress factors that can induce papillomatosis in fish.
Recurrent respiratory papillomatosis (RRP) is characterized by the development of laryngeal papillomas, which can produce partial to complete upper airway obstruction. Patients with RRP often require intermittent surgical excision to treat symptoms such as hoarseness and stridor, and to control
OBJECTIVE
To investigate the safety of peri-operative management on children with juvenile recurrent respiratory papilloma (JORRP).
METHODS
A retrospective analysis was conducted on preoperative assessment, anesthesia methods and options, operative procedure, and postoperative airway maintenance in
OBJECTIVE
To evaluate the efficacy and safety of a spontaneous ventilation anesthesia technique with insufflation of oxygen and volatile agent through a double-lumen central venous catheter (DLCVC) in pediatric patients undergoing suspension laryngoscopic surgery for laryngeal
OBJECTIVE
The purpose of this study is to investigate REDD1-(regulated in development and DNA damage response 1) mediated regulation of the mammalian target of rapamycin (mTOR) pathway in breast cancer.
METHODS
A tissue microarray included samples from 224 patients with breast cancer, and 30
Tumor hypoxia regulates many cytokines and angiogenic factors (CAF) and is associated with worse prognosis in head and neck squamous cell cancer (HNSCC). Serum CAF profiling may provide information regarding the biology of the host and tumor, prognosis, and response to therapy. We investigated 38
An animal model for the early detection of common fatal diseases such as ischemic diseases and cancer is desirable for the development of new drugs and treatment strategies. Hypoxia-inducible factor 1 (HIF-1) is a transcription factor that regulates oxygen homeostasis and plays key roles in a number
Hypoxia-inducible factor-1 (HIF-1) is a known cancer progression factor, promoting growth, spread, and metastasis. However, in selected contexts, HIF-1 is a tumor suppressor coordinating hypoxic cell cycle suppression and apoptosis. Prior studies focused on HIF-1 function in established malignancy;
OBJECTIVE
Human papilloma virus-associated head and neck squamous cell carcinomas (HNSCC) represent a distinct subgroup of HNSCC characterized by a favorable prognosis and a distinct molecular biology. There is a range of unresolved questions regarding the different biology and clinical outcome of
BACKGROUND
The p53 protein is involved in the regulation of initiation of apoptosis. In vitro, p53-deficient cells do not respond to hypoxia with apoptosis as do p53-normal cells, and this may lead to a relative growth advantage of cells without a functioning p53 under hypoxia. On the basis of this
OBJECTIVE
To investigate the expression and clinical significance of phosphatase and tensin homology deleted on chromosome ten (PTEN) and hypoxia-inducible factor 1 alpha (HIF-1α) in sinonasal inverted papilloma (SNIP) of different pathological grades.
METHODS
Fifty-five paraffin samples from
p53 is a widely known tumor-suppressor gene product that plays a key role in apoptotic cell death induced by DNA-damaging chemotherapeutic agents. Human glioma cells with functional p53 are known to be more resistant to γ-radiation. The aim of this study was to investigate whether the mutant
OBJECTIVE
To investigate the expression profile of the hypoxia-inducible transcription factor-1α (HIF-1α) and its downstream targets in malignancies of the ocular adnexa and to determine its relevance as a prognostic factor for clinical outcome.
METHODS
We included 49 subjects with malignant tumours
MicroRNA (miRNA) expressions in tumor biopsies have shown potential as biomarkers in cervical cancer, but suitable reference RNAs for normalization of reverse transcription quantitative polymerase chain reaction (RT-qPCR) assays in patient cohorts with different clinicopathological characteristics
