BACKGROUND: Estrogen signalling is transmitted via various receptors and multiple intracellular signalling pathways. Estrogen receptor alpha (ERα)-mediated transcription of target genes has been demonstrated to be closely linked to human papilloma virus (HPV)-induced carcinogenesis in case of cervical cancer. So far, the role of non-genomic estrogen signals in cervical cancer, e.g. transmitted by the G protein-coupled estrogen receptor (GPER) remains to be rather elusive. Today's knowledge on the role of GPER in cervical cancer is sparse and-to the best of our knowledge-GPER has not been investigated in context with clinicopathological parameters or prognosis of cervical cancer...

Targeting endoplasmic reticulum (ER) stress is being investigated for its anticancer effect in various cancers, including cervical cancer. However, the molecular pathways whereby ER stress mediates cell death remain to be fully elucidated. In this study, we confirmed that ER stress triggered by compounds such as brefeldin A (BFA), tunicamycin (TM), and thapsigargin (TG) leads to the induction of the unfolded protein response (UPR) in cervical cancer cell lines, which is characterized by elevated levels of inositol-requiring kinase 1α, glucose-regulated protein-78, and C/EBP homologous protein, and swelling of the ER observed by transmission electron microscope (TEM)...

BACKGROUND AND OBJECTIVE: Bleeding into the retropharyngeal space is a potential complication in stellate ganglion block (SGB). Retropharyngeal hematoma formation is considered to be due to damage of small arteries in the region, although only scanty details of the region are available. The aim of this study was to map the risk blood vessels in the retropharyngeal space to avoid accidental damage during SGB. METHODS: Contrast-enhanced 3-dimensional computed tomography images performed on 80 patients were reanalyzed retrospectively to construct detailed map of cervical blood vessels that are prone to damage and bleeding during SGB...

High-risk human papillomaviruses (hr HPVs) may cause various human cancers and associated premalignant lesions. Transformation of the host cells is triggered by overexpression of the viral oncogenes E6 and E7 that deregulate the cell cycle and induce chromosomal instability. This process is accompanied by hypermethylation of distinct CpG sites resulting in silencing of tumor suppressor genes, inhibition of the viral E2 mediated control of E6 and E7 transcription as well as deregulated expression of host cell microRNAs...

Despite the excellent biocompatibility and antifouling effect of poly(ethylene glycol) (PEG), the high steric hindrance, limited chemical functionality, and low ligand multivalency of PEGylated nanocarriers often lead to inefficient cell targeting and intracellular trafficking. Hence, a new structure of hydrophilic corona allowing a higher ligand density without loss of excellent biocompatibility is highly desirable. Here we introduce tumor-targeted polyglycerolated (PGylated) nanocarriers that dramatically enhance the in vivo therapeutic efficacy of incorporated paclitaxel simply by increasing the surface density of hydrophobic tumor-targeting ligands...

BACKGROUND: Anterior cervical discectomy with fusion is an effective treatment for patients having cervical radiculopathy and myelopathy. To reduce morbidity associated with autograft taken from the iliac crest without sacrificing high fusion rates, a novel technique that harvests bone from the vertebral body adjacent to the operative disc space has been proposed. The effects of square and round bone graft harvest techniques on the mechanical stability of the osteopenic donor vertebrae are unknown...

AIMS: Preganglionic cervical root avulsion (PCRA) affects both the peripheral and central nervous systems and is often associated with neuropathic pain. Unlike peripheral nerve injuries (PNI), central lesions caused by disruption of cervical roots from the spinal cord following PCRA contribute to the generation of neuropathic pain. Leptin is involved in the development of neuropathic pain after PNI by affecting neurons. However, whether leptin is involved in microglial activation leading to neuropathic pain after PCRA is unknown...

In order to improve the efficacy of photodynamic therapy (PDT), biotin was axially conjugated with silicon(IV) phthalocyanine (SiPc) skeleton to develop a new tumor-targeting photosensitizer SiPc-biotin. The target compound SiPc-biotin showed much higher binding affinity toward BR-positive (biotin receptor overexpressed) HeLa human cervical carcinoma cells than its precursor SiPc-pip. However, when the biotin receptors of HeLa cells were blocked by free biotin, >50% uptake of SiPc-biotin was suppressed, demonstrating that SiPc-biotin could selectively accumulate in BR-positive cancer cells via the BR-mediated internalization...

REVIEW
Leo Han, Rebecca Taub, Jeffrey T Jensen
The properties of cervical mucus vary in response to both natural and artificial hormonal changes. During ovulatory cycles, cervical mucus becomes increasingly fluid and favorable to sperm penetration as estradiol levels increase. Following ovulation, as estradiol levels decrease and progesterone increases, the mucus increases in viscosity and becomes impenetrable to sperm. Cervical mucus thickening also occurs in response to synthetic progestins administered by various routes, and this is commonly believed to represent the essential contraceptive mechanism of progestin-only methods that do not block ovulation...

More and more studies have reported that dysregulation of microRNAs (miRNAs) lead to the proliferation and EMT of multiple cancers. Recently, several reports have demonstrated that dysregulation of miR-4262 is in numerous cancers. However, its role and precise mechanism in human cervical cancer (CC) have not been well clarified. Hence, my study was aim to explore the biological roles and precise mechanisms of miR-4262 in CC cell lines. In my study, I found that the level of miR-4262 is significantly decreased in CC tissues and cell lines...

BACKGROUND: Interscalene brachial plexus block is currently the gold standard for intra- and post-operative pain management for patients undergoing arthroscopic shoulder surgery. However, it is associated with block related complications, of which effect on the phrenic nerve have been of most interest. Side effects caused by general anesthesia, when this is required, are also a concern. We hypothesized that the combination of superficial cervical plexus block, suprascapular nerve block, and infraclavicular brachial plexus block would provide a good alternative to interscalene block and general anesthesia...
