Kidney organoids: steps towards better organization and function.

Kidney organoids - 3D representations of kidneys made either from pluripotent or tissue stem cells - have been available for well over a decade. Their application could confer notable benefits over longstanding in vivo approaches with the potential for clinically aligned human cells and reduced ethical burdens. They been used, at a proof-of-concept level, in development in disease modeling (including with patient-derived stem cells), and in screening drugs for efficacy/toxicity.

Serum myeloperoxidase, paraoxonase, and plasma asprosin concentrations in patients with acute myocardial infarction.

Introduction: The objective of this study was to evaluate the usefulness of the serum biomarkers myeloperoxidase (MPO), paraoxonase (PON), and plasma asprosin in acute myocardial infarction (AMI) diagnosis and assess their compatibility with routinely screened cardiac biomarkers.

Methods: This study was conducted using a prospective cross-sectional design and included 90 patients, consisting of 60 patients diagnosed with AMI (30 with ST-segment elevation and 30 with non-ST-segment elevation on ECG) and 30 controls (without a diagnosis of AMI). Changes in the levels of cardiac biomarkers (Hs-cTnI, CK, CK-MB), lipid profile (TC, TG, LDL, HDL), MPO, PON, asprosin, and routine biochemical parameters of patients were evaluated.

Investigation of serum and adipose tissue levels of asprosin in patients with severe obesity undergoing sleeve gastrectomy.

Objective: This study aimed to reveal the relationship between obesity and asprosin (fibrillin-1) in patients undergoing bariatric surgery and to investigate the role of asprosin in obesity etiopathogenesis.

Methods: The study included 37 patients who underwent laparoscopic sleeve gastrectomy for severe obesity and 37 patients who underwent laparoscopic cholecystectomy for cholelithiasis in the study and control groups, respectively. Blood samples were collected from the patients in the preoperative period to measure biochemical parameters.

Proteome analysis of the circadian clock protein PERIOD2.

Circadian rhythms are a series of endogenous autonomous 24-h oscillations generated by the circadian clock. At the molecular level, the circadian clock is based on a transcription-translation feedback loop, in which BMAL1 and CLOCK transcription factors of the positive arm activate the expression of CRYPTOCHROME (CRY) and PERIOD (PER) genes of the negative arm as well as the circadian clock-regulated genes. There are three PER proteins, of which PER2 shows the strongest oscillation at both stability and cellular localization level.

Evaluation of Blood Urea, Creatinine, and Glucose Levels as Biochemical Indicators of the Type and Severity of Traumatic Brain Injury.

Aim: To investigate the effects of trauma type and survival on biochemical parameters including blood urea, creatinine, and glucose levels on patients with traumatic brain injury (TBI).

Material And Methods: The medical records of 102 patients with TBIs who were admitted to the emergency department and/ or hospitalized in the neurosurgery department between 2016 and 2019 were examined retrospectively.

Results: Types of trauma included: 19 cases of subarachnoid hemorrhage, 25 cases of subdural hemorrhage, 9 cases of epidural hemorrhage, 28 cases of intracerebral hemorrhage, 4 cases of multiple hemorrhage, and 12 cases with other hemorrhages.

The combined effect of pomegranate extract and tangeretin on the DMBA-induced breast cancer model.

The aim of this study was to investigate the protective effects of pomegranate extract and tangeretin alone or in combination in DMBA-induced rat breast cancer model. A total of 68 female rats were randomly divided into 8 groups. The first 4 groups were designed as controls for cancer and treatment groups, and the control groups were composed of only control (C), Pomegranate (P), Tangeretin (T), and Pomegranate+Tangeretin (P+T) groups.

The effect of diclofenac sodium intoxication on the cardiovascular system in rats.

Objectives: Diclofenac sodium (DS) is a widely used nonsteroidal anti-inflammatory drug. Although its high doses are known to cause toxic effects in many tissues including liver and kidney, the effects on the cardiovascular system (CVS) have not been fully elucidated yet. Therefore, this study aimed to investigate the effect of DS on CVS.

The protective effect of chrysin against carbon tetrachloride-induced kidney and liver tissue damage in rats.

The aim of this study was to investigate the possible protective effects of chrysin on oxidative status and histological alterations against carbon tetrachloride (CCl)-induced liver and kidney tissue in rats. The animals were randomly divided into four groups; the control, chrysin (100 mg/kg), CCl (0.5 ml/kg) and chrysin + CCl groups.

Severe Traumatic Brain Injury Cases among Children Younger than 24 Months.

Introduction: Accidental head injuries are known to cause serious traumatic brain injury (TBI). Children younger than 2 years of age build a separate group that is more difficult to assess clinically. Investigations targeting TBIs in pediatric cases, particularly in those between 0 and 2 years of age, are limited.

Ischemic postconditioning reduced myocardial ischemia-reperfusion injury: The roles of melatonin and uncoupling protein 3.

Objective: Protective effects of ischemic postconditioning (PostC) decrease/disappear with age and chronic heart diseases. Similarly, low serum melatonin levels have been reported in the same risk groups. The aims of this study were to investigate the effects of melatonin on the protection of PostC in ischemia-reperfusion (I/R)-induced infarct size and roles of uncoupling protein (UCP) 3, irisin, and nuclear factor kappa B (NFkB) levels.

The therapeutic effects of thalidomide and etanercept on septic rats exposed to lipopolysaccharide.

Background: The aim of this study was to evaluate the therapeutic effects of thalidomide and etanercept on lipopolysaccharide (LPS)-induced sepsis in a rat model.

Methods: Thirty male Wistar Albino rats were divided into 5 groups: Control, LPS, LPS+Thalidomide, LPS+Etanercept, and LPS+Thalidomide+Etanercept. The control group was given a 1 mL intraperitoneal (i.

Effect of apelin hormone on renal ischemia/reperfusion induced oxidative damage in rats.

Apelin is a peptide hormone defined as a ligand for G-protein clamped receptor (APJ) receptor. It is indicated in the literature both apelin and APJ are synthesized on the peripheral tissues including the renal tissues. Which roles does the apelin play on the renal tissue has not been completely illuminated yet.
