Paraurethral cysts are usually asymptomatic and frequently detected incidentally during routine pelvic examination however, patients can present with complaints of a palpable cyst or with lower urinary tract symptoms (LUTS) and also dyspareunia. In most cases, diagnosis can be made on physical examination but for more detailed evaluation and to differentiate from malign lesions ultrasonography (US), voiding cystourethrogram (VCUG), computerized tomography (CT), or magnetic resonance imaging (MRI) can also be used...

The major development of the past decade in the first-line treatment of recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) was the introduction of cetuximab in combination with platinum plus 5-fluorouracil chemotherapy (CT), followed by maintenance cetuximab (the "EXTREME" regimen). This regimen is supported by a phase 3 randomized trial and subsequent observational studies, and it confers well-documented survival benefits, with median survival ranging between approximately 10 and 14 months, overall response rates between 36 and 44%, and disease control rates of over 80%...

Immune checkpoint inhibitors (ICIs) have emerged as a promising treatment option in the fight against advanced non-small-cell lung cancer (NSCLC). KRAS is the most frequently mutated oncogene in NSCLC. We performed this meta-analysis to investigate if KRAS mutation status affects survival benefits of ICIs in patients with advanced NSCLC. Electronic databases were searched for eligible studies. We included randomized trials with the data of overall survival stratified by KRAS mutation status. From 3 eligible studies, 138 patients with KRAS mutant NSCLC and 371 with KRAS wild-type tumor were included in the meta-analysis...

Regular exercise-training is known to affect the action potential duration (APD) and improve heart function, but the involvement by β-adrenergic receptor (β-AR) subtypes and/or KATP channel is unknown. To address this, female and male Sprague-Dawley rats were randomly assigned to voluntary wheel running or control groups and after 6-8 weeks training anesthetized and myocytes isolated. Exercise-training significantly increased APD of apex and base myocytes at 1Hz, while decreasing the APD at 10Hz. Ca(2+) transient durations reflected the changes observed in APD, while Ca(2+) transient amplitudes were unaffected by wheel running...

BACKGROUND: Advances in cancer immunotherapy have generated encouraging results in multiple malignancies refractory to standard chemotherapies. As the use of immune checkpoint inhibitors (ICI) proliferates, the incidence of autoimmune side effects associated with these agents, termed immune related adverse events (irAE), is expected to increase. The frequency of significant irAE in ICI treated patients is about 10-20% and early recognition is critical to prevent serious morbidity and even mortality...

The pathogenesis of psoriatic itch is poorly understood. The aim of this study was to investigate the involvement of opioid receptors in scratching behaviour of imiquimod-induced psoriasis-like dermatitis model mice. Topical application of 5% imiquimod cream to the rostral back skin of mice induced antihistamine-resistant scratching behaviour. The expression of µ-opioid receptor (MOR) protein increased in the epidermis, dorsal root ganglia (DRG) and spinal cord of imiquimod-treated mice. In contrast, the expression of κ-opioid receptor (KOR) protein decreased in the DRG and spinal cord of imiquimod-treated mice, and was undetectable in the epidermis of both groups...

Glioblastoma (GBM) is resistant to most multimodal therapies. Clinical success of immune-checkpoint inhibitors (ICIs) has spurred interest in applying ICIs targeting CTLA4, PD1 or IDO1 against GBM. This amplifies the need to ascertain GBM's intrinsic susceptibility (or resistance) toward these ICIs, through clinical biomarkers that may also "guide and prioritize" preclinical testing. Here, we interrogated the TCGA and/or REMBRANDT human patient-cohorts to predict GBM's predisposition toward ICIs. We exploited various broad clinical biomarkers, including mutational or predicted-neoantigen burden, pre-existing or basal levels of tumor-infiltrating T lymphocytes (TILs), differential expression of immune-checkpoints within the tumor and their correlation with particular TILs/Treg-associated functional signature and prognostic impact of differential immune-checkpoint expression...

BACKGROUND: For every six men, one will be diagnosed with prostate cancer (PCa) in their lifetime. Estrogen receptors (ERs) are known to play a role in prostate carcinogenesis. However, it is unclear whether the estrogenic effects are mediated by estrogen receptor α (ERα) or estrogen receptor β (ERβ). Although it is speculated that ERα is associated with harmful effects on PCa, the role of ERβ in PCa is still ill-defined. The cholesterol oxidized metabolite 27-hydroxycholesterol (27-OHC) has been found to bind to ERs and act as a selective ER modulator (SERM)...

It has been suggested that β2-adrenergic receptor (β2-AR)-mediated signaling induced by catecholamines regulates the degradation of p53. However, the underlying molecular mechanisms were not known. In the present study, we demonstrated that catecholamines upregulated the expression of silent information regulator 1 (Sirt1) through activating β2-AR-mediated signaling pathway, since selective β2-AR antagonist ICI 118, 551 and non-selective β-blocker proprenolol effectively repressed isoproterenol (ISO)-induced Sirt1 expression...

Adoptive cell therapies with chimeric antigen receptor (CAR) engineered T cells (CAR-T) and immune checkpoint inhibition (ICI)-based cancer immunotherapies have lately shown remarkable success in certain tumor types. CAR-T cell-based therapies targeting CD19 can now induce durable remissions as well as prolong disease-free survival of patients with CD19 positive treatment refractory B cell malignancies and ICI-based therapies with humanized monoclonal antibodies against the T cell inhibitory receptors CTLA-4 and PD-1 as well as against the PD-1 ligand, PD-L1, can now achieve durable remissions as well as prolongation of life of a sizeable fraction of patients with melanoma and Hodgkin's lymphoma and non-small cell cancers...

Icariin, the major ingredient of Herba Epimedii, promotes the osteogenic differentiation of rat bone marrow stromal cells (rBMSCs) and exerts protective effects against bone loss and increases bone regeneration, but the underlying signaling pathway by which icariin affects osteogenic differentiation remain unclear. Transcriptional coactivator with PDZ-binding motif (TAZ) is a transcriptional modulator of the Hippo signaling pathway, which plays an important role in the osteogenic differentiation of BMSCs by activating Runx2 gene during the terminal osteogenic differentiation...

Recent studies suggest an anti-inflammatory activity of oxyresveratrol, a stilbene extracted from Cortex mori root used in traditional Chinese medicine that also presents estrogen-like activity. We herein tested the hypothesis that oxyreservatrol exerts an anti-inflammatory effect through its estrogenic-like function. In MCF-7 cells, oxyresveratrol significantly induced proliferation, which was accompanied with estrogen receptor (ER)-mediated transcriptional activation, increased estrogen-targeted gene expression (e...

Immune checkpoint inhibitors (ICIs) have been approved for patients with advanced non-small-cell lung cancer (NSCLC), regardless of histology. However, histologic subtypes of NSCLC may influence treatment outcomes of ICIs. We conducted this meta-analysis to investigate if there is difference in survival benefits of ICIs between squamous (SQ) and non-squamous (non-SQ) NSCLC. We searched PubMed, MEDLINE, EMBASE and ESMO databases. We included randomized controlled trials with the data of survival outcomes in advanced NSCLC patients treated with ICIs...

Estrogen plays important roles in regulation of bone formation. Chloride channels in the ClC family are expressed in osteoblasts and are associated with bone physiology and pathology, but the relationship between chloride channels and estrogen is not clear. In this study, the action of estrogen on chloride channels was investigated in osteoblastic MC3T3-E1 cells. Results showed that 17β-estradiol could activate a current which reversed at a potential close to Cl(-) equilibrium potential with the anion selectivity I- >Br->Cl->gluconate and was inhibited by the chloride channel blockers 5-nitro-2-(3-phenylpropylamino)-benzoate (NPPB) and 4,4'-Diisothiocyano-2,2'-stilbenedisulfonic acid (DIDS) and knockdown of ClC-3 chloride channel expression...

Previous studies have demonstrated the endocrine disruption of o,p'-DDT. In this study, we used a (1)H NMR based metabolomics approach to investigate the estrogenic effects of o,p'-DDT (300 mg/kg) on the uterus and brain after 3 days of oral gavage administration, and ethynylestradiol (EE, 100 μg/kg) was used as a positive control. A supervised statistical analysis (PLS-DA) indicated that o,p'-DDT exerted both estrogenic receptor-(ER)-dependent and independent effects on the uterus but mainly ER-independent effects on the brain at metabolome levels, which was verified by coexposing with the antiestrogenic ICI 182,780...

Bisphenol A (BPA) acts as xenoestrogen and has a great impact on disorders of human reproductive system. However, the mechanism through which BPA can affect human testicular function remains to be indentified. GPR30 is a novel membrane estrogen receptor with high-affinity and low-capacity binding to estrogens. We demonstrated that estrogen receptor α (ERα), estrogen receptor β (ERβ) as well as GPR30 are expressed in mouse spermatocyte-derived GC-2 cells using Real-time PCR. We treated the cells with different doses of BPA and found that even low doses of BPA can inhibit GC-2 cell growth using MTT assay...

AIMS AND METHODS: A think tank was convened at the sixth ICI-RS meeting held in the United Kingdom on September 2015, to consider the adequacy of patient reported outcome (PRO) measurement if quality of life (QoL) evaluation were excluded. Rigorous methodology is proposed for the development of PROs and much is written about this process but the necessity for QoL inclusion is rarely discussed. The decision was therefore taken to consider what QoL evaluation provides and what these data provide...
