Characterizing localized nitrogen sensitivity of tree species and the associated influences of mediating factors.

Critical loads (CLs) are frequently used to quantify terrestrial ecosystem impacts from nitrogen (N) deposition using ecological responses such as the growth and mortality of tree species. Typically, CLs are reported as a single value, with uncertainty, for an indicator across a species' entire range. Mediating factors such as climate and soil conditions can influence species' sensitivity to N, but the magnitudes of these effects are rarely calculated explicitly.

Pure low-grade DCIS in a male patient: a case report.

Breast cancer in males represents a small proportion of all cancers diagnosed. Pure ductal carcinoma in situ (DCIS), a low-grade form of breast cancer, is even more rare in male patients. We present a case of a 47-year-old male patient with a tender breast lump that was noted for 6 months.

Axillary node metastatic carcinoma without definitive primary: a case report.

Cancer of unknown primary (CUP) is the finding of a metastatic cancerous lesion without an established primary source localized within the body. CUP can be of any cancer cell type, however, adenocarcinoma is most often identified by histology. Up to 5% of all malignant diagnoses are classified as CUP.
