    The aim of this study was to evaluate the effects of beta -1,3-(D)-glucan as an antioxidant and tissue protective agent and study the biochemical, histopathologic, and immunohistochemical effects of first therapeutic proteasome inhibitor bortezomib on the liver for treating relapsed multiple myeloma. The experiment included 36 adult male rats, which were divided into four treatment groups: control (healthy); bortezomib-treated; beta-1,3-D-glucan-treated; and bortezomib + beta-1,3-(D)-glucan-treated. Each group was subdivided into two subgroups based on time of sacrifice (48 or 72 h). After the experiments, superoxide dismutase (SOD) activity and lipid peroxidation (LPO) amounts were determined, and immunohistochemical and histopathological changes were examined in all rat liver tissues. beta -1,3-(D)-Glucan treatment normalized changes of LPO and stimulated an over activity of endogenous SOD. The results of the histopathologic parameters showed that treatment with beta -1,3-(D)-Glucan in the bortezomib group ameliorated the development of non-specific reactive hepatitis (NSRH) and Kupffer cell activation via NF-kB. Administration of beta -1,3-(D)-Glucan is effective in reversing tissue damage induced by bortezomib in rat livers.Bu çalışmanın amacı, relaps multiple miyelom tedavi etmek için kullanılan ilk terapötik proteazom inhibitörü olan bortezomibin karaciğer üzerine immunohistokimyasal, histopatolojik ve biyokimyasal etkilerini araştırmak ve bir antioksidant ve doku koruyucu ajan olarak B-1,3-(D)-glukanın etkilerini değerlendirmekdi. Deney; kontrol (sağlıklı), bortezomib ile tedavi, B-1,3-(D)-glukan ile tedavi ve bortezomib + B-1,3-(D)-glukan ile tedavi olmak üzere dört tedavi grubuna bölünen 36 yetişkin erkek sıçan içerdi. Her bir grup sakrifikasyon zamanına (48 veya 72 saat) göre iki alt gruba ayrıldı. Deneylerin bitiminden sonra, süperoksit dismutaz (SOD) aktivitesi ve lipid peroksidasyon (LPO) miktarları ölçüldü ve tüm sıçan karaciğer dokularında immünohistokimyasal ve histopatolojik değişiklikler incelendi. B-1,3-(D)-glukan ile tedavi LPO değişikliğini normalize etti ve endojen SOD aktivitesi aşırı uyardı. Histopatolojik parametrelerin sonuçları, bortezomib grubunda B-1,3-(D)-glukan ile tedavi NF-kB yoluyla Kupffer hücre aktivasyonunu ve non-spesifik reaktif hepatit (NSRH) gelişimini regüle ettiğini gösterdi. B-1,3-(D)-glukan uygulaması, sıçan karaciğerinde bortezomibin neden olduğu geri döndürülebilir doku hasarında efektifdir

    In this study, serum carnitine (CRNT) and adiponectin (APN) levels and the correlation of these parameters in patients with breast cancer before and after treatment with radiotherapy (RT) were determined

    WOS: 000376906600019PubMed ID: 27192502Objectives: This study aimed to investigate the relationship between breast magnetic resonance imaging (MRI) parameters; clinical features such as age, tumor diameter, N, T, and TNM stages; and serum human epididymis protein 4 (HE4) levels in patients with breast carcinoma and use this as a means of estimating possible signaling pathways of the biomarker, HE4. Methods: Thirty-seven patients with breast cancer were evaluated by breast MRI and serum HE4 levels before therapy. Correlations between parameters including age, tumor diameter T and N, dynamic curve type, enhancement ratio (ER), slope wash in (S-WI), time to peak (TTP), slope washout (S-WO), and the serum level of HE4 were investigated statistically. Human epididymis protein 4 levels of early and advanced stage of disease were also compared statistically. Results: Breast MRI parameters showed correlation to serum HE4 levels and correlations were statistically significant. Of these MRI parameters, S-WI had higher correlation coefficient than the others. Human epididymis protein 4 levels were not statistically different in early and advanced stage of disease. Conclusions: High correlation with MRI parameters related to neo-angiogenesis may indicate signaling pathway of HE4
