Article Synopsis
  • Irisin, a peptide released from skeletal muscle during exercise, may significantly influence energy metabolism and interacts with thyroid hormones, which regulate metabolic rates.
  • Central administration of irisin to rats for 7 days increased food intake without altering body weight, indicating its potential role in energy regulation.
  • The study found that irisin administration decreased levels of key thyroid hormones and gene expression related to the hypothalamus while also enhancing thermogenic activity in adipose and muscle tissues, suggesting its complex role in energy balance.

Allograft lithiasis is a rare urologic complication of renal transplantation (RT). Our aim is to present our experience with minimally invasive surgical treatment of allograft lithiasis in our series of live-donor renal transplant recipients. In a retrospective analysis of 3758 consecutive live-donor RTs performed in our center between November 2009 and January 2017, the results of minimally invasive surgery for the treatment of renal graft lithiasis diagnosed at follow-up were evaluated.

Purpose: The aim of this study is to compare the results of transurethral incision of the prostate (TUIP) and transurethral resection of the prostate (TURP) for the surgical treatment of benign prostate hyperplasia (BPH) in patients with renal transplantation.

Materials And Methods: Between April 2009 and May 2016, BPH patients with renal transplants whose prostate volumes were less than 30 cm3 were treated surgically. Forty-seven patients received TURP and 32 received TUIP.

Purpose: To assess baseline T2-weighted signal intensity (T2-WSI) of functional pituitary adenomas (FPA), and to investigate the relationship of baseline T2-WSI with clinical features, histopathological granulation patterns, and response to treatment in patients with acromegaly, prolactinoma and Cushing's disease (CD).

Methods: Somatotroph adenomas (n = 87), prolactinomas (n = 78) and corticotroph adenomas (n = 29) were included in the study. Baseline T2-WSI findings (grouped as hypo-, iso- and hyperintense) were compared with hormone levels, tumor diameter, granulation patterns and response to treatment.

The aim of this study was to evaluate the impact of intracerebroventricular chronic fibroblast growth factor 21 (FGF21) infusion on hypothalamic-pituitary-thyroid (HPT) axis, energy metabolism, food intake and body weight. Thirty male Wistar albino rats were used and divided into three groups including control, sham (vehicle) and FGF21 infused groups (n = 10). Intracerebroventricularly, FGF21 and vehicle groups were infused for 7 days with FGF21 (0.

A new coumarin-thiazole based Schiff base (Ligand, L) and its Pd(II), Pt(II) complexes; ([Pd(L)] and [Pt(L)]), were synthesized and characterized using spectrophotometric techniques (NMR, IR, UV-vis, LC-MS), magnetic moment, and conductivity measurements. A single crystal X-ray analysis for only L was done. The crystals of L have monoclinic crystal system and P21/c space group.

Background: The use of a ureteral stent can cause a urinary tract infection (UTI), although it reduces urologic complications. UTIs are associated with a higher rate of ureteral stent colonization (USC). The aim of this study was to compare USC in living and deceased donor renal transplant recipients.

Objectives: The aim of this study was to retrospectively evaluate the early and long-term results of renal transplantation (RT) patients undergoing transurethral resection of the prostate (TURP) due to benign prostate hyperplasia (BPH).

Materials And Methods: Eighty-nine patients with RT performed in our hospital underwent TURP between November 2008 and March 2016. Results were evaluated along with early and long-term complications.

Article Synopsis
  • The study aimed to assess the occurrences and outcomes of open globe injuries (OGI) in children aged 16 or younger, by reviewing medical records from 1996 to 2015.
  • Out of 892 patients, the annual incidence was found to be higher in boys, with most injuries occurring in children aged 3 to 7, primarily during summer months, often at playgrounds.
  • The research highlighted that many pediatric OGIs lead to significant vision loss, but some patients showed varying degrees of visual recovery, suggesting that careful treatment approaches are necessary.

Purpose: The aim of this study was to evaluate anatomic properties of the lens capsule and iris by anterior segment optical coherence tomography (AS-OCT) in patients with pseudoexfoliation (PEX).

Methods: This prospective study included 62 eyes of 62 patients with PEX syndrome and 43 eyes of 43 age- and gender-matched controls. All subjects underwent full ophthalmologic examinations including AS-OCT.

Urinary tract infections are a major cause of morbidity and hospitalization after renal transplantation. Patients treated with immunosuppressive drugs suffer not only from common uropathogens but also from opportunistic infections caused by unusual uropathogens. Sterile pyuria is associated with numerous infectious agents including viruses, fungi, and atypical or fastidious organisms.

Aim: In recent studies, it has been shown that the Transient Receptor Potential Melastatin-2 Channels (TRPM2) and Phospholipases A2 (PLA) inhibitors may have a protective effect on neurons. This study was aimed to investigate the protective effect of TRPM2 and PLA inhibitor N-(p-amylcinnamoyl) Anthranilic Acid (ACA) in a neurodegenerative model induced by Okadaic Acid (OKA).

Main Methods: OKA (200ng/10μl) was administered bilateral intracerebroventricularly as a single injection.

Background: Depending on hyphothalamic, hyphophyseal, and gonadal axis dysfunction, anovulatory irregular cycles occur and the probability of pregnancy decreases in the patients with chronic kidney disease (CKD). Maternal mortality and morbidity rates are increased in CKD patients; the risk of premature delivery is 70% and the risk of preeclampsia is 40% more than normal among those with a creatine level of >2.5 mg/dL.

Herpes simplex virus-1 (HSV-1) causes life-long morbidities in humans. While fever blisters are more common, occasionally the cornea is infected resulting in vision loss. A very intriguing aspect of HSV-1 corneal infection is that the virus spread is normally restricted to only a small fraction of cells on the corneal surface that connect with each other in a dendritic fashion.

Background: In cancer, apoptosis relevant proteins-such as CaM kinase, Bcl-2 or P53, topoisomerase I, cell migration feature and DNA/BSA-macromolecules represent significant targets for current chemotherapeutics.

Objective: We recently reported two coordination compounds-[Cu(C6H16N2O2)2][Ni(CN)4] (1) and [Cu(C6H16 N2O2)Pd(CN)4] (2)-together with their IR spectra, magnetic properties, thermal analyses and crystal structures. Herein, we describe the ability of these complexes to induce apoptosis in relevant proteins and stimulate topoisomerase I activity, cell migration velocity and DNA/BSA binding properties.
