Sparc/osteonectin, cwcv, and kazal-like domains proteoglycan 1 () is an oncogene that promotes tumor formation and progression in certain types of cancer and is associated with poor survival rates. However, there is limited information on the importance of in gynecological cancers in the literature. The aim of this study was to explore the role of in ovarian serous cystadenocarcinoma (OV), cervical squamous cell carcinoma and endocervical adenocarcinoma (CESC), and uterine corpus endometrial carcinomas (UCEC).

Objective: Breast cancer (BC) is a global concern due to its high incidence worldwide. The alarming increase in BC cases highlights the need for careful management of the disease at multiple levels. This study investigated the diagnostic value of hemoglobin, albumin, lymphocyte and platelet counts (HALP score), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR) and lymphocyte-to-monocyte ratio (LMR) in newly diagnosed BC patients.

Background: Epoxyeicosatrienoic acids (EETs) are closely associated with lipoprotein metabolism, and changes in lipid profiles potentially affect their levels and functions. Given the alterations in lipid metabolism after cholecystectomy, this study aimed to investigate the levels of four EET regioisomers (free and esterified) and lipid profiles in patients with cholelithiasis after laparoscopic cholecystectomy (LC) and explore correlations between these parameters.

Methods: This prospective study involved 40 patients with symptomatic cholelithiasis who underwent LC.

Background: PC is among the cancer types with high incidence and mortality. New and effective strategies are being sought for the treatment of deadly cancers, such as PC. In this context, the use of nanocarrier systems containing titanium dioxide can improve treatment outcomes and increase the effectiveness of anticancer drugs.

Article Synopsis
  • This study investigates the role of neuropeptide receptors (HCRTR1, HCRTR2, NPY4R) and associated genes (PPY, PTPN11) in breast cancer by using bioinformatics tools on large patient datasets.
  • Significant mutations were found, with decreased expression of HCRTR1 linked to poorer overall and relapse-free survival, while elevated levels of HCRTR2 and PPY correlated with better outcomes.
  • The study also revealed hypermethylation of HCRTR1 and NPY4R, while HCRTR2 and PPY were hypomethylated, indicating complex regulatory patterns affecting their gene expressions in breast cancer.

Aims: We aimed to examine the role of circulating immature granulocytes (IGs) in assessing Diabetic Nephropathy (DN) mainly and also associations of other leukocyte parameters with DN.

Methods: In this retrospective cross-sectional study, a total of 164 Diabetes Mellitus patients were grouped as normoalbuminuric and microalbuminuric according to urinary albumin excretion in the course of admission. Neutrophil-lymphocyte ratio (NLR), IG count (IG#) and IG percentage (IG%) levels were compared between the groups.

Background: The aim of our study is to compare plasma ferritin levels found to be high or low in terms of reference range by means of electrochemiluminescence (ECLIA) and immunoturbidimetric method and to examine whether they can be used interchangeably.

Methods: 84 patients with high plasma ferritin level and 153 patients with low ferritin level according to the re ference range were included in the study. Plasma samples measured in Cobas e601 device with ECLIA were also measured as immunoturbidimetric Cobas c501 device.

Background: The aim of this study is to examine the relationship among the changes in activities of paraoxonase (PON), arylesterase (ARE) and homocysteine thiolactonase (HTLase) enzyme having antioxidant properties and the development of diabetic nephropathy (DN), one of the most common complications of diabetes.

Methods: Normoalbuminuric type-2 diabetic patients (Group II, n=100), microalbuminuric type 2 diabetic patients (Group III, n=100) and the control group (Group I, n=100) were included in the study. The age and gender of the patient groups matched with the age and gender of the control group.

BACKGROUND The aim of the present study was to compare procalcitonin and CRP levels in maternal serum and fetal cord blood samples of patients with idiopathic intrauterine growth restriction (IUGR) vs. a control group of appropriate for gestational age (AGA) infants. MATERIAL AND METHODS The present prospective study included 43 patients: 27 patients with idiopathic IUGR (IUGR group) and 26 AGA infants at similar gestational ages (control group).
