Alterations in energy consumption and plantar pressure distribution during walking in young adults with patellofemoral pain syndrome

Objective

The aim of this study was to determine the alterations of walking energy expenditure and plantar pressure distribution in young adults with patellofemoral pain syndrome (PFPS).

Resorufin Enters the Photodynamic Therapy Arena: A Monoamine Oxidase Activatable Agent for Selective Cytotoxicity

A red-absorbing, water-soluble, and iodinated resorufin derivative (R1) that can be selectively activated with a monoamine oxidase (MAO) enzyme was synthesized, and its potential as a photodynamic therapy (PDT) agent was evaluated. R1 showed high ¹O₂ generation yields in aqueous solutions upon addition of MAO isoforms, and it was further tested in cell culture studies. R1 induced photocytotoxicity after being triggered by endogenous MAO enzyme in cancer cells with a much higher efficiency in SH-SY5Y neuroblastoma cells with high MAO-A expression. Additionally, R1 displayed differential cytotoxicity between cancer and normal cells, without any considerable dark toxicity. To the best of our knowledge, R1 marks the first example of a resorufin-based photosensitizer (PS) as well as the first anticancer drug that is activated by a MAO enzyme. Remarkably, the target PDT agent was obtained only in three steps as a result of versatile resorufin chemistry.     

Comment on “The effect of omalizumab on hematological and inflammatory parameters in patients with chronic spontaneous urticarial”: reply from authors

Abstract

We read Cosansu’s commentary entitled “Effectiveness of the new inflammatory parameters in patients with chronic spontaneous urticarial” to our study with great interest. The author remarked that a limited number of patients had C-reactive protein levels and it was not specified whether there were any other drugs used by the patients and no information was given about the severity of the disease in our study.     

Chronic hepatitis B in children with or without malignancies:A 13-year follow-up

AIM:To evaluate the outcome of chronic hepatitis B(CHB)in children with or without malignancies.METHODS:Twenty four children(15 boys and 9 girls)with malignancies,followed up by the pediatric gastroenterology outpatient clinic for CHB between January 2000 and December 2013,were enrolled in the study(Group 1).Group 2 was formed with twenty five children(11 girls and14 boys)diagnosed with CHB without malignancies.The data from the patients’records were compared between the two groups.RESULTS:Hepatitis B e antigen(HBe Ag)/anti HBe seroconversion was observed in 3 patients(12.5%)in group 1 and 15 patients(60%)in group 2,with annual seroconversion rates of 1.61%and 16.6%,respectively,and the difference was significant(P0.01).One patient(6.6%)in Group 1 and 9 patients(53%)in Group 2 showed HBe Ag/anti HBe seroconversion after treatment and the difference between the two groups was significant(P0.06)Loss of hepatitis B surface antigen was observed in one patient in each of group1 and 2.No clinical,laboratory and imaging findings of liver disease were observed in any of the patients at the end of the study.CONCLUSION:HBe Ag/anti HBe seroconversion rate was lower in patients who had recovered from cancer.
