Differential Expression of p53 in Mycosis Fungoides, Sezary Syndromes, and Their Transformed Forms.

Mycosis fungoides (MF) and Sezary syndrome (SS) are common entities among primary cutaneous lymphomas. Large cell transformation is challenging for diagnosis and therapy. Molecular mechanisms by which these lymphomas undergo this transformation are poorly defined.

Pesticide presence in stream water, suspended sediment and biofilm is strongly linked to upstream catchment land use and crop type.

Pesticide pollution can present high ecological risks to aquatic ecosystems. Small streams are particularly susceptible. There is a need for reproducible and readily available methods to identify aquatic regions at risk of pesticide contamination.

Dietary exposure of stormwater contaminants in biofilm to two freshwater macroinvertebrates.

Aquatic habitats in urban environments are exposed to complex contaminant mixtures that may harm aquatic biota. The impact of contaminant transfer from contaminated biofilm through aquatic food webs is still understudied, as is the current state of knowledge on dietary exposure of urban contaminants to biota residing in stormwater ponds. Our overall objective was to characterize urban pesticide accumulation in a common aquatic food source (biofilm) in stormwater ponds and to investigate the potential toxicity of that food source by testing the responses of two freshwater macroinvertebrates to experimental exposure.

Lymphocytic Esophagitis Associated With Chronic Severe Psoriasis: A Case Report With Special Reference to Programmed Death-Ligand 1 Expression.

Lymphocytic esophagitis (LE) is a rare type of chronic esophagitis, marked by an increased number of peripapillary intraepithelial lymphocytes (IEL) with little to no presence of intraepithelial granulocytes and intercellular edema. There is currently no established standard for quantifying IEL in the esophageal mucosa. Clinically, LE manifests with a range of symptoms, including difficulty swallowing (dysphagia), indigestion (dyspepsia), nausea, and chest pain.
