Introduction We investigated the association of the neutrophil/lymphocyte ratio (NLR) with tumor size and Fuhrman grade in nonmetastatic renal cell carcinoma (RCC) cases. Materials and methods Data of nonmetastatic RCC (T1-4N0M0) cases, operated between 2010 and 2016, were retrospectively reviewed and 103 patients were included in the study. The patients were divided into two groups according to tumor diameter (Group 1 T < 4 cm, Group 2 T ≥ 4 cm) and into three groups according to Fuhrman grade. Twenty-eight patients with a tumor diameter of 4 cm or less in Group 1 and 75 patients with a tumor diameter greater than 4 cm in Group 2 were compared...

Eagle syndrome is defined as symptomatic elongation of the styloid process or calcification of the stylohyoid and stilomandibular ligament. The syndrome was described by WW Eagle in 1937. The styloid process is located between the internal and external carotid arteries and laterally in the tonsillar fossa. Patients with cerebrovascular ischemia causing syncope or hemiparesia due to Eagle syndrome are rarely published in the literature. The authors presented a patient with recurrent cerebrovascular attacks due to long styloid process...

Disklike molecules with aromatic cores spontaneously stack up in linear columns with high, one-dimensional charge carrier mobilities along the columnar axes, making them prominent model systems for functional, self-organized matter. We show by high-resolution optical birefringence and synchrotron-based x-ray diffraction that confining a thermotropic discotic liquid crystal in cylindrical nanopores induces a quantized formation of annular layers consisting of concentric circular bent columns, unknown in the bulk state...

For the first time, the molecular mobility of two linear-shaped tetramethylated guanidinium triflate ionic liquid crystals (ILCs) having different lengths of alkyl chains was investigated using a combination of broadband dielectric spectroscopy (BDS) and specific heat spectroscopy (SHS). By self-assembly, these ILCs can form a hexagonal ordered mesophase besides plastic crystalline phases and the isotropic state. Three dielectric active processes were found using BDS for both samples. At low temperatures, a γ-process in the plastic crystalline state is observed which is assigned to localized fluctuations of methyl groups including nitrogen atoms in the guanidinium head...

Malignant mesothelioma of the tunica vaginalis testis (MMTVT) is an extremely rare tumour, usually mimicking benign pathologies of the scrotum. Our case is an 84-year-old male patient who appealed with a painless, left-sided scrotal swelling longer than 2 months. Although the level of tumour markers was normal, ultrasonographic examination results forced us to perform an inguinal scrotal exploration. Multiple small papillary tumours, both on tunica vaginalis and tunica albuginea, were detected intraoperatively...

Testicular cancer represents approximately 1% of all cancers diagnosed in males. The prevalence of bilateral testicular germ cell tumor cases varies from 1% to 5%. Intratubular germ cell neoplasia (ITGCN) is a precursor for almost all testicular germ cell tumors (TGCT) and is one of the highest risks of developing contralateral testicular cancer. The radical orchiectomy is still preferred for the treatment of testicular cancer. However, in some cases like solitary testis, bilateral cancer or if the tumor size is under 30% percent of the testicular extent, organ-sparing surgery can be an option...

According to the thermal melanism hypothesis, darker coloured melanic individuals heat up faster and to higher temperatures than lighter coloured individuals due to lower skin reflectance. Consequently, it is assumed that darker melanic types may be advantageous compared to light coloured types in colder regions. As temperature gradually decreases with elevation and latitude the degree of melanism is expected to increase along these gradients in ectothermic species. Isophya rizeensis, a colour polymorphic bush cricket species endemic to Northeastern Turkey is an interesting case since the degree of melanism decreases with elevation, contrary to the thermal melanism hypothesis...
