Photodynamic therapy (PDT) is a minimally-invasive surgical tool successfully targeting premalignant and malignant disorders in the head and neck, gastrointestinal tract, lungs and skin with greatly reduced morbidity and disfigurement. The technique is simple, can commonly be carried out in outpatient clinics, and is highly acceptable to patients. The role of photodynamic therapy in the managem...

Presented article suggests the novel hypothesis of carcinogenesis, where the key moment for all types of carcinogenesis (biological, physical, chemical) has been discussed. The thorough theoretical analysis of the mechanisms of malignant transformation of cells after influence of carcinogens has been presented. Hypothesis highlights importance of mitochondrial electron transport chain alteratio...

BACKGROUND Humans vary in their ability to metabolize endogenous and exogenous compounds. Glutathione S-transferases (GSTs) and N-acetyltransferases (NATs) are enzymes involved in the detoxification of hazardous agents. The GSTM1 and GSTT1 genes exhibit null (i.e., deletion) polymorphisms; in specific individuals, homozygous deletion (i.e., both copies lost) of these genes can be detected. Poly...

Charts of 1006 consecutive outpatients were reviewed to ascertain the cause of extreme elevation of the erythrocyte sedimentation rate (ESR) (greater than or equal to 100 mm/h) and the sensitivity of marked ESR elevation in patients with disorders commonly reported to cause ESR elevation. Prevalence of ESRs of 100 mm/h or more was 4.2%. Infection was the most common cause (33%), with malignant ...

Autoimmune diseases (ADs) have close relationship with the onset of malignant lymphoma. They closely tie to lymphoma. Immune disorders might play an important role in transformation from ADs to lymphoma. DLBCL occurred after autoimmune hematological diseases and autoimmune lymphoproliferative syndrome (ALPS) was rare. The interval between ADs and DLBCL was long and the pathogenesis might be rel...
