In this study, we aimed to review the diagnostic approach to eosinophilic cell renal neoplasms by light microscopy and immunohistochemical techniques. ⋯ The panel with RCCm, GST-α, EpCAM, CD117, CK7 will contribute to the differentiation of eosinophilic cytoplasm renal tumors that cannot be determined by morphological findings and to reach the correct diagnosis (Tab. 3, Fig. 4, Ref. 54). Text in PDF www.elis.sk Keywords: RCC, oncocytoma, immunohistochemistry.

The aim of the present study was to investigate the neuroprotective effect of ceftriaxone in a rat brain ischemia/reperfusion injury model. ⋯ These results suggest that ceftriaxone could be beneficial for the prevention of brain ischemia/reperfusion injury caused by acute arterial occlusion through reducing the tissue MDA level (Tab. 2, Fig. 5, Ref. 24).

In the pregnancy period, it is recommended to limit the consumption of caffeine. However, the mechanisms of caffeine effect during pregnancy are not fully known. In our study, we aimed to investigate the effect of prenatal caffeine consumption on the embryonic implantation in rats as well as shed light on the relationship between the molecules and implantation stages.MATERIALS AND METHODS: Forty-five Wistar albino pregnant rats were randomly divided into 3 main groups, namely into control, low‑dose and high‑dose groups, representing the dose-dependent effects of caffeine. Each main group was divided into 3 subgroups, namely those to be sacrified on days 4 (pre-implantation), 5 (peri-implantation) and 6 (post-implantation) . Different doses of caffeine were given on consecutive days, starting from day 1 of pregnancy up to the day of euthanasia. The implantation sites were investigated with the use of hematoxylin et eosin, Masson trichrome and immunostaining of VEGF, MMP-9, integrin αVβ3, mucin-1 and HB-EGF. ⋯ It has been shown that the levels of integrin αVβ3 and MMP-9 were decreased by prenatal caffeine consumption in rats, which resulted in a decrease in embryo implantation in a dose-dependent manner, especially in the high-dose group (Fig. 5, Ref. 36). Text in PDF www.elis.sk Keywords: caffeine, embryo implantation, integrin, MMP-9.

The study was designed to evaluate the possible adverse effects and consequences of metal oxide nanoparticles used on some major body organ functions and health parameters. ⋯ The present study confirmed the health risks of the use of metal oxide nanoparticles in the medical field without precautions and supervision; and may encourage application of nanoparticles from alternative origins, such as plants, algae, or microorganisms instead (Tab. 5, Fig. 4, Ref. 30) Keywords: nanoparticles, thyroid, parathyroid, kidney, oxidative stress, blood, green, alternative.

Recent breakthrough recognition of metastasis-free survival as a clinically relevant endpoint has opened a new era in the management of advanced prostate cancer. The need for new, intermediate endpoints is the logical consequence of scientific advances in prostate carcinoma. The treatment algorithms for non-metastatic castration-resistant prostate cancer (M0 CRPC) have recently been updated by adding novel anti-androgen apalutamide, and also enzalutamide for high-risk patients. ⋯ The metastasis-free survival can be considered a clinically significant and reliable efficacy endpoint in both localized prostate cancer patients and M0 CRPC patients being at high-risk of disease progression (Ref. 15).
