Augmentation of Docetaxel-Induced Cytotoxicity in Human PC-3 Androgen-Independent Prostate Cancer Cells by Combination With Four Natural Apoptosis-Inducing Anticancer Compounds.

Docetaxel (DTX) is the treatment of choice for metastatic castration-resistant prostate cancer. However, developing drug resistance is a significant challenge for achieving effective therapy. This study evaluated the anticancer and synergistic effects on DTX of four natural compounds (calebin A, 3-hydroxypterostilbene, hispolon, and tetrahydrocurcumin) using PC-3 androgen-resistant human prostate cancer cells.

Nesfatin-1, Dopamine, and NADPH levels in Infertile Women with Polycystic Ovary Syndrome: Is There a Relationship Between Their Levels and Metabolic and Hormonal Variables.

Background: Polycystic ovary syndrome (PCOS) is commonest endocrine disease occurring in women of reproductive age. This study conducted to clarify altered concentrations of Nesfatin-1, nicotinamide adenine dinucleotide phosphate (NADPH), and dopamine in PCOS women and controls. Also, to assess their role in PCOS pathophysiology and their correlation with measured biochemical parameters.

Treatment Efficiency of Different Routes of Bone Marrow-Derived Mesenchymal Stem Cell Injection in Rat Liver Fibrosis Model.

Background/aims: The most appropriate route for bone marrow-derived mesenchymal stem cell (BM-MSC) transplantation in the management of liver fibrosis remains controversial. This study investigated the therapeutic efficacy of intravenous and intrasplenic BM-MSC transplantation on carbon tetrachloride (CCl4)-induced rat liver fibrosis.

Methods: Fifty rats were divided into 5 groups (n = 10 rats per group): healthy control group, CCl4 group, CCl4/ recovery group, CCl4/BM-MSC intravenous group, and CCl4/BM-MSC intrasplenic group.

Physiological Responses and Gene Expression in Ultrasound-Guided Supraclavicular Brachial Plexus Block: a Comparative Study.

Background/aims: Ultrasound-guided supraclavicular brachial plexus block (BPB) has come into wider use as a regional anesthetic during upper limb operations. This study assessed the neurological and hemodynamic changes and gene expression after co-administration of midazolam or neostigmine with bupivacaine during supraclavicular BPB.

Methods: The study involved 90 adults divided into three groups: control (bupivacaine), midazolam (bupivacaine plus midazolam), and neostigmine (bupivacaine plus neostigmine).

Comparison of the therapeutic effectiveness of human CD34 and rat bone marrow mesenchymal stem cells on improvement of experimental liver fibrosis in Wistar rats.

Background And Objective: Human umbilical cord blood (UCB) cells and bone marrow mesenchymal stem cells (BM-MSCs) have numerous advantages as grafts for cell transplantation. We hypothesized differing impacts of human UCB cells and rat BM-MSCs on reversal of hepatic injury and revival of liver function in carbon tetrachloride (CCl)-induced liver fibrosis.

Methods: Forty rats were divided into 4 groups; control group, CCl group, CCl/CD34 group and CCl/BM-MSCs group.

The Number of GT(n) Repeats in the Hemeoxygenase-1 Gene Promoter is Increased in Pediatric Heart Failure but is Unrelated to Renal, Antioxidant and Anti-inflammatory Markers.

Products of hemeoxygenase (HO)-1 have anti-inflammatory and antioxidant functions. The HO-1 promoter has a variable number of GT(n) repeats: A low number (n < 23) is associated with high transcriptional activity in response to oxidative stress. We hypothesized that the frequency of GT(n) repeats in pediatric heart failure (HF) reflects plasma biomarkers of different disease processes: the soluble receptor for advance glycation end products (sRAGE, marking cellular activation), oxLDL (oxidative stress), NGAL (impaired renal function), HIF-1α (hypoxia) and hsCRP (inflammation).

The effect of melatonin on plasma markers of inflammation and on expression of nuclear factor-kappa beta in acetic acid-induced colitis in the rat.

Background And Aims: Melatonin may be involved in gastrointestinal tract physiology and could affect inflammation-related gastrointestinal disorders. Rat models of ulcerative colitis imply melatonin is beneficial. To determine potential pathophysiological mechanisms, we assessed colonic nuclear factor-kappa beta expression and measured serum levels of pentraxin-3, lipid peroxides, and total thiols in an acetic acid model of this disease.
