BACKGROUND: Gastric and colon cancer cells express the neurokinin-1 receptor (NK-1R) and the peptide substance P (SP), after binding to this receptor, elicits the proliferation of gastrointestinal cancer cells and an antiapoptotic effect. In these cells, NK-1R antagonists (L-733,060: a piperidine derivative; aprepitant: a morpholine derivative) block, after binding to the NK-1R, the action of SP and exert an antiproliferative action, both antagonists promote apoptosis and the death of cancer cells...

Leuprolide acetate (LEU), also known as Lupron, is commonly used to treat prostate cancer in men. As a gonadotropin-releasing hormone (GnRH) receptor agonist, it initially stimulates the release of gonadal hormones, testosterone (T) and estradiol. This surge eventually suppresses these hormones, preventing the further growth and spread of cancer cells. Individuals receiving this treatment often report anxiety and cognitive changes, but LEU's effects on the neural mechanisms that are involved in anxiety during the trajectory of treatment are not well known...

INTRODUCTION: Primary apocrine sweat gland carcinoma (PASGC) is an extremely rare neoplasia whose management and treatment are still evolving. The only curative therapy is wide local excision. Many patients have metastasis at the time of the diagnosis, mainly because this neoplasm has been misdiagnosed as some benign skin lesions. PRESENTATION OF CASE: We herein report a case of a 72-year-old-man with PASGC affecting the axilla and regional lymph nodes that underwent surgical resection and lymphadenectomy at our Institution...

Aiming at improved therapeutic efficacies, the combination of chemotherapy and radiotherapy (chemo-radiotherapy) has been widely studied and applied in clinic. However, the hostile characteristics of tumor microenvironment such as hypoxia often limit the efficacies in both types of cancer therapies. Herein, catalase (CAT), an antioxidant enzyme, is encapsulated inside liposomes constituted by cisplatin (IV)-prodrug-conjugated phospholipid, forming CAT@Pt (IV)-liposome for enhanced chemo-radiotherapy of cancer...

Exhaled aerosol patterns have been used to detect obstructive respiratory diseases in the upper airways. Signals from small airway diseases are weak and may not manifest themselves in the exhaled aerosol patterns. Therefore, it will be more challenging to detect abnormalities in small airways. The objective of this study is to develop a simulation-based classification model that can accurately classify small airway diseases. The model performance was evaluated in five obstructed models that are located in lung bifurcations G7-9...

An extensive number (965) of rice samples collected by household survey from 73 upazilas (i.e. sub-districts) in Bangladesh was analyzed to determine regional variation, distribution and associated health risks from arsenic (As). No previous study had conducted a study examining such a large number of rice samples. The mean and median concentrations of total As were 126μg/kg and 107μg/kg, respectively, ranging from between 3 and 680μg/kg. Importantly, total As levels of aromatic rice were significantly lower (average 58μg/kg) than non-aromatic rice (average 150μg/kg) and also varied with rice grain size...

There is an increasing trend towards using oral systemic therapy in patients with cancer. Compared to parenteral therapy, oral cancer agents offer convenience, have similar efficacy, and are preferred by patients, consequently making its use appealing in older adults. However, adherence is required to ensure its efficacy and to avoid compromising treatment outcomes, especially when the treatment goal is curative, or in case of symptomatic/rapidly progressing disease, where dose-intensity is important. This opens a new challenge for clinicians, as optimizing patient adherence is challenging, particularly due to lack of consensus and scarcity of available clinical evidence...

During the last decades, important advances in therapeutic options have led to increased survival rates in cancer patients; however, cancer treatments are associated with several potential adverse effects including infertility in those diagnosed during their reproductive years. A proper discussion about fertility preservation options before the use of therapies with potential gonadotoxicity (i.e. oncofertility counseling) is standard of care and should be offered to all patients of childbearing age. Temporary ovarian suppression with LH-RH analogs, oocyte and embryo cryopreservation are standard strategies for fertility preservation in female cancer patients...

Combined immune checkpoint blockade (ICB) provides unprecedented efficacy gains in numerous cancer indications, with PD-1 inhibitor nivolumab plus CTLA-4 inhibitor ipilimumab in advanced melanoma as first-ever approved therapies for combined ICB. However, gains in efficacy must be balanced against a higher frequency and severity of adverse drug reactions (ADR). Because delays in diagnosis and management might result in symptom worsening and further complications, clinicians shall be well trained to identify ADR promptly and monitor patients adequately...

Long noncoding RNAs (lncRNAs), as new class of functional regulators involved in human tumorigenesis, have been attracting increasing attention of researchers. The lncRNA Colorectal Neoplasia Differentially Expressed (CRNDE), transcribed from chromosome 16 on the strand opposite to the adjacent IRX5 gene, were originally found to be increased in CRC and was reported abnormal expressed in many cancers. However, its potential role and molecular mechanism underlying radioresistant phenotype formation of lung adenocarcinoma (LAD) remains unclear...

Recent evidence suggests that dysregulation of microRNAs are associated with the development of multiple malignancies.miR-186 has been reported as a critical cancer regulator in several types of cancers. However, its functional significance and molecular mechanism underlying renal cell carcinoma (RCC) remains unknown. In this study, our results showed that miR-186 expression was dramatically downregulated in RCC tissues and cell lines compared to that in adjacent normal tissues and cell lines. Overexpression of miR-186 significantly inhibited cell growth, colony formation, cell invasion, caused cell cycle arrest at G0/G1 phase, and induced cell apoptosis as detected by MTT, colony formation, Transwell assay, and flow cytometry assays in RCC cells...

MicroRNAs (miRs) have been found to play promoting or suppressive roles in different human cancers. However, the exactregulatory mechanism of miR-30b in glioblastoma still remains unknown. Here we showed that the expression of miR-30b was significantly increased in glioblastoma tissues and cell lines. Moreover, high expression of miR-30b was significantly associated with shorter survival time of glioblastoma patients. Knockdown of miR-30b caused a significant reduction in the proliferation, migration, and invasion of U87 and A172 cells...

Drug resistance is the major obstacle for the successful therapy of lung adenocarcinoma. It was suggested that ß-elemene, a major isoform of elemene, could reverse the drug resistance in lung cancer cells. However, the underlying mechanisms remains poorly known. Here, we aimed to investigate whether elemene is involved in the cisplatin (DDP)-resistance of lung adenocarcinoma cells and further explore the underlying mechanism. The results showed that human lung adenocarcinoma cell line SPC-A-1 and its DDP-resistant strain SPC-A-1/DDP had a similar sensitivity to elemene treatment...

MicroRNAs play an important role in regulating gene expression by binding to the 3' UTR of target mRNAs. In this studywe have made an attempt to assess the molecular mechanisms by which miR-32 suppresses the expression of SRCIN1, thereby leading to promotion of proliferation and epithelial-mesenchymal transition of human liver cancer cells. Human liver cancer cell lines HepG2 were transfected with miR-32 mimics and its control. The HepG2 cell lines were the assessed for miR-32 expression. The transfected cell lines were then studied for SRCIN1 expression by luciferase assay, effect of transfection on cell proliferation and finally epithelial-mesenchymal transition...
