The freshwater-marine transition that characterizes an estuarine system can provide multiple entry options for invading species, yet the relative importance of this gradient in determining the functional contribution of invading species has received little attention. The ecological consequences of species invasion are routinely evaluated within a freshwater versus marine context, even though ma...

Invasive species are nonindigenous species that are introduced into new environments, where they become established and expand their range [1]. They undergo rapid proliferation following the colonization of new habitats, often at the expense of native species, thus having a negative impact on biodiversity. The prospering discipline of invasion ecology seeks to understand why some species become...

introduction: breast cancer is the second most common cause of brain metastasis. although patient prognosis is poor, isolated brain metastasis occasionally can be an option for treatment with curative intent in breast cancer patients. case presentation: we report a patient with invasive ductal carcinoma of the breast who developed an isolated right frontal lobe metastasis within 5 months of fin...

Lobular carcinoma in situ (LCIS) clinically constitutes a risk factor for the subsequent development of either invasive lobular carcinoma (ILC) or invasive ductal carcinoma (IDC). In order to approach the possibility of this common precursor of both ILC and IDC, we investigated combined lobular and ductal carcinomas. Thirty-two cases of lobular carcinoma were picked up out of 773 cases of opera...

BACKGROUND Histamine(2)-receptor antagonist (H(2) blocker) medications are used to treat heartburn, gastroesophageal reflux disease, and ulcers. Some H(2) blockers, specifically cimetidine and ranitidine, also increase serum prolactin concentrations. Given the positive relationship between prolactin levels and postmenopausal breast cancer risk, use of H(2) blockers is a potential breast cancer ...

Background & Objectives: Anaplastic lymphoma Kinase (ALK) is a receptor tyrosine kinase involved in the genesis of several human cancers. ALK was initially identified because of its involvement in anaplastic large cell lymphoma (ALCL). ALK is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops. Studies reveal that the presence of anti-ALK antibodies ...

Pancreatic ductal adenocarcinoma (PDAC), a common digestive system cancer, is highly malignant and has a poor disease outcome. Currently, all available examination and detection methods cannot accurately predict the clinical outcome. Therefore, it is extremely important to identify novel molecular biomarkers for personalized medication and to significantly improve the overall outcome. The "nonc...

Background : Breast-Conserving surgery (BCS) has generally been limited to T1 and T2 lesions because it has been thought impossible to achieve good local control with satisfactory cosmesis in patient with more advanced disease. However, many patients with T3 and T4 lesions will exhibit dramatic tumor down staging with neoadjuvant Chemotherapy. Several studies reports low rates of breast conserv...

Radiotherapy is an indispensible part of the management of all stages of breast cancer. In this article, the common indications for radiotherapy in the management of early breast cancer (stages 0, I, and II) are reviewed, including whole-breast radiotherapy as part of breast-conserving treatment for early invasive breast cancer and pre-invasive disease of ductal carcinoma in situ, post-mastecto...

Researchers at Memorial Sloan-Kettering Cancer Center have investigated many aspects of their experience with ductal carcinoma in situ of the breast over the past 20 years. This paper summarizes the most clinically relevant findings.
