Targeting the FGFR signaling pathway in cholangiocarcinoma: promise or delusion?

Cholangiocarcinoma (CCA) is a refractory cancer with limited treatment options and poorly understood molecular mechanisms underlying tumor development. The most effective treatment is surgical resection; however, patients are highly prone to recurrence. Moreover, considering that most patients are diagnosed in advanced stages, treatment options are restricted to palliative care, which results in poor prognosis. Due to the limited effect of chemotherapy and radiotherapy, targeted therapy is becoming a hot topic in the field of biliary cancer treatment. The fibroblast growth factor/fibroblast gr

Effects of cyclophosphamide combined with prednisone on TNF-α expression in the treatment of patients with interstitial lung disease (ILD), and its clinical significance were investigated. A prospective analysis was performed on 198 patients with ILD in Jinan Central Hospital Affiliated to Shandong University from January 2010 to December 2017. Among them, 101 patients treated with cyclophosphamide combined with prednisone were assigned in the combined treatment group, and 97 patients treated with prednisone alone in the control group. Patients in the two groups were compared in terms of lung

Escaping Antiangiogenic Therapy: Strategies Employed by Cancer Cells.

Tumor angiogenesis is widely recognized as one of the "hallmarks of cancer". Consequently, during the last decades the development and testing of commercial angiogenic inhibitors has been a central focus for both basic and clinical cancer research. While antiangiogenic drugs are now incorporated into standard clinical practice, as with all cancer therapies, tumors can eventually become resistant by employing a variety of strategies to receive nutrients and oxygen in the event of therapeutic assault. Herein, we concentrate and review in detail three of the principal mechanisms of antiangiogenic

Awareness on hematological malignancies among college students.

Cancers of blood arise when the abnormal blood cells undergo uncontrolled growth which outpaces the natural production of normal blood cells, interfering with the cells' normal functions. Leukemia, lymphoma, and myeloma are the three types of blood cancers. The aim of our study is to assess and create awareness of hematological malignancies among college students. A questionnaire was prepared using Google Forms based on the awareness of the Hematological malignancies disinfection methods among dental students in Chennai. It was then circulated among a certain set of participants using an onlin

Cardiogenic shock among cancer patients.

Sophisticated cancer treatments, cardiovascular risk factors, and aging trigger acute cardiovascular diseases in an increasing number of cancer patients. Among acute cardiovascular diseases, cancer treatment, as well as the cancer disease itself, may induce a cardiogenic shock. Although increasing, these cardiogenic shocks are still relatively limited, and their management is a matter of debate in cancer patients. Etiologies that cause cardiogenic shock are slightly different from those of non-cancer patients, and management has some specific features always requiring a multidisciplinary appro

New Generation of Meso and Antiprogestins (SPRMs) into the Osteoporosis Approach.

Receptor activator of nuclear factor κB (RANK) and its ligand (RANKL) play key roles in bone metabolism and the immune system. The RANK/RANKL complex has also been shown to be critical in the formation of mammary epithelia cells. The female hormones estradiol and progesterone closely control the action of RANKL with RANK. Blood concentration of these sex hormones in the postmenopausal period leads to an increase in RANK/RANKL signaling and are a major cause of women's osteoporosis, characterized by altered bone mineralization. Knowledge of the biochemical relationships between hormones and RAN

Therapeutic potential of Fingolimod in triple negative breast cancer preclinical models.

Surgery followed by a chemotherapy agent is the first-line treatment for breast cancer patients. Nevertheless, new targets are required for women with triple-negative breast cancer (TNBC) in order to improve the treatment of this aggressive cancer subtype. Multiple pro-inflammatory molecules including lipid-based substances such as sphingosine-1-phosphate (S1P) promote cancer progression. In this preclinical study, we aim to investigate the efficacy of Fingolimod, an inhibitor of S1P / S1P receptors axis, already approved as an immunomodulator in multiple sclerosis. The impact of Fingolimod wa

Nanotechnology and Matrix Metalloproteinases in Cancer Diagnosis and Treatment.

Cancer is still one of the leading causes of death worldwide. This great mortality is due to its late diagnosis when the disease is already at advanced stages. Although the efforts made to develop more effective treatments, around 90% of cancer deaths are due to metastasis that confers a systemic character to the disease. Likewise, matrix metalloproteinases (MMPs) are endopeptidases that participate in all the events of the metastatic process. MMPs' augmented concentrations and an increased enzymatic activity have been considered bad prognosis markers of the disease. Therefore, synthetic inhib

MMPs are involved in angiogenesis, including the activation of TECs and lymphangiogenesis (MMP-2, MMP-3, MMP-9, MMP-13, MMP-14, and MMP-16, not shown in the figure). …

Bench-to-bedside review: Angiopoietin signalling in critical illness - a future target?

Multiple organ dysfunction syndrome (MODS) occurs in response to major insults such as sepsis, severe haemorrhage, trauma, major surgery and pancreatitis. The mortality rate is high despite intensive supportive care. The pathophysiological mechanism underlying MODS are not entirely clear, although several have been proposed. Overwhelming inflammation, immunoparesis, occult oxygen debt and other mechanisms have been investigated, and - despite many unanswered questions - therapies targeting these mechanisms have been developed. Unfortunately, only a few interventions, usually those targeting mu

Oral toxicity produced by chemotherapy: A systematic review.

IntroductionAntineoplastic chemotherapy remains one of the most widely used management strategies in cancer, either alone or in combination with other types of treatment. The main inconvenience of chemotherapy is its lack of selectivity, since it acts upon both tumor cells and rapidly multiplying normal cells such as bone marrow cells, hair follicle cells and oral and gastrointestinal mucosal cells.Material and methodAn exhaustive search was made of the main oral toxic effects of chemotherapy in the PubMed-Medline, Cochrane Library and Scopus databases. A total of 1293 articles were identified

Role of macrophages in the pathogenesis of atopic dermatitis.

Atopic dermatitis (AD) is one of the most common and most intensively studied chronic inflammatory skin diseases. Several cofactors, such as an impaired skin barrier function, modifications of the immune system, and a complex genetic background, direct the course of AD. Within this complex network, macrophages play a pivotal role in enhanced susceptibility to cutaneous infections and act as central connecting components in the pathogenesis of AD on the cellular level. In AD, macrophages are known to accumulate in acutely and chronically inflamed skin. During the early and short inflammatory ph

PURPOSE: To evaluate the diagnostic efficacy of apparent diffusion coefficient (ADC) measurements and semi-quantitative dynamic contrast enhancement (DCE) parameters in predicting the differentiation between low- and high-grade tumors in non-muscle invasive bladder cancers (NMIBC). METHODS: Patients with NMIBC, who were histopathologically confirmed between August 2020 and July 2023, were analyzed by 2 radiologists with different levels of experience. DCE semi-quantitative parameters such as wash-in rate (WiR), wash-out ratio (WoR), time to peak (TTP), and peak enhancement (PE) were calculate

B-cells in pulmonary arterial hypertension: friend, foe or bystander?

There is an unmet need for new therapeutic strategies that target alternative pathways to improve the prognosis of patients with pulmonary arterial hypertension (PAH). As immunity has been involved in the development and progression of vascular lesions in PAH, we review the potential contribution of B-cells in its pathogenesis and evaluate the relevance of B-cell-targeted therapies. Circulating B-cell homeostasis is altered in PAH patients, with total B-cell lymphopenia, abnormal subset distribution (expansion of naïve and antibody-secreting cells, reduction of memory B-cells) and chronic acti
