Understanding Uncertainty in Market-Mediated Responses to US Oilseed Biodiesel Demand: Sensitivity of ILUC Emission Estimates to GLOBIOM Parametric Uncertainty.

The life cycle greenhouse gas (GHG) emissions of biofuels depend on uncertain estimates of induced land use change (ILUC) and subsequent emissions from carbon stock changes. Demand for oilseed-based biofuels is associated with particularly complex market and supply chain dynamics, which must be considered. Using the global partial equilibrium model GLOBIOM, this study explores the uncertainty in market-mediated impacts and ILUC-related emissions from increasing demand for soybean biodiesel in the United States in the period 2020-2050.

Seasonal patterns of Schistosoma mansoni infection within Biomphalaria snails at the Ugandan shorelines of Lake Albert and Lake Victoria.

Intestinal schistosomiasis is hyperendemic in many sub-Saharan African countries. In Uganda, it is endemic at both Lake Albert (LA) and Lake Victoria (LV) and caused by S. mansoni that uses Biomphalaria snails as obligatory intermediate snail hosts.

Robotic Cytoreductive Surgery With Heated Intraperitoneal Chemotherapy.

Cytoreductive surgery with heated intraperitoneal chemotherapy (CRS-HIPEC) is traditionally an open operation given the dissection required during cytoreduction. There are reports of minimally invasive HIPECs, but CRS to an accepted completeness of cytoreduction (CCR) has been described less frequently. We report a patient with metastatic low-grade mucinous appendiceal neoplasm (LAMN) to the peritoneum treated with robotic CRS-HIPEC.

Management of Neuroendocrine Ductal Carcinoma In Situ of the Breast.

Neuroendocrine tumors are defined as tumors that express neuroendocrine markers, specifically synaptophysin and/or chromogranin in at least 50% of tumor cells. To date, neuroendocrine cancers of the breast are extremely rare with reports that they account for less than 1% of all neuroendocrine tumors and less than .1% of all breast cancers.

Management of Hidden Cutaneous Melanoma of the Umbilicus.

Melanoma is currently the fifth most common cancer in the United States (US) and most often develop on areas that have increased sun exposure, such as the arms, legs, back or face. The incidence of primary cutaneous melanoma increases each year and curative treatment improves with earlier detection of disease. Primary cutaneous umbilical melanoma is extremely rare with as few as 46 cases reported worldwide.
