Mechanistic understanding of asphaltene precipitation and oil recovery enhancement using SiO and CaCO nano-inhibitors.

Asphaltene precipitation in oil reservoirs, well equipment, and pipelines reduces production, causing pore blockage, wettability changes, and decreased efficiency. Asphaltenes, with their unique chemical structure, self-assemble via acid-base interactions and hydrogen bonding. Nano-inhibitors prevent asphaltene aggregation at the nanoscale under reservoir conditions.

Comparing the Effect of Clonidine and Dexmedetomidine on Intraoperative Bleeding in Spine Surgery.

Background: Discopathy is one of the most common spinal surgeries. Hemodynamic control is important in bleeding reduction during the surgery. Clonidine and dexmedetomidine both are α agonists that help stabilize hemodynamics and prevent the increase of intraoperative bleeding.

Bone Metabolism Disorder in Epileptic Children.

Objective: There are frequent anti-epileptic drugs used in management of epilepsy. Anti-epileptic drugs may have some complications on bone and vitamin D metabolism. This study aimed to comparison the bone metabolism disorder in epileptic children with healthy child in Zahedan, eastern Iran from Jul 2014 to Jun 2015.

Comparison between brain natriuretic peptide and calcitonin gene-related peptide in children with dilated cardiomyopathy and controls.

Background: Dilated cardiomyopathy (DCM) is revealed with the left ventricular dilatation and systolic dysfunction.

Objective: This study was performed to determine the level of calcitonin gene-related peptide (CGRP) and brain natriuretic peptide (BNP) in children with DCM and controls and comparison of these two biomarkers in patients.

Materials And Methods: This study was performed from April 2014 to March 2015 on patients with DCM.

Serum Levels of Tumor Necrosis Factor-α and Interleukins in Children with Congenital Heart Disease.

Levels of anti-inflammatory cytokines in blood have a positive relationship with congenital heart disease (CHD). We sought to assess the difference in serum cytokines levels between children with and without CHD. We recruited 60 patients with CHD and 30 healthy children, from 2013 to 2014.

Evaluation of serum level of tumor necrosis factor-alpha and interleukin-6 in patients with congenital heart disease.

Background: The objective of the study is to assess the levels of tumor necrosis factor-alpha (TNF-α) and interleukin-10 (IL-10) in patients with congenital heart diseases (CHDs) and control.

Patients And Methods: In this case-control study, sixty patients with CHD with ages of 1 month to 15 years and thirty healthy subjects were assessed. All objects measured in height, weight, age, sex, and body mass index (BMI).

Evaluation of oxidant-antioxidant balance and total antioxidant capacity of serum in children with urinary tract infection.

Background: Urinary tract infection (UTI) is the most common bacterial infections in children. This studyaimed to investigate the oxidative and antioxidate status of plasma in patients with UTI and to compare them with those of the controls.

Methods: This case-control study of 50-75 children in the given order was performed in 2013 at the Pediatric Clinic of infections in Zahedan Hospital of Ali Ibn Abi Talib.

The perception of primiparous mothers of comfortable resources in labor pain (a qualitative study).

Background: Natural delivery is the most painful event that women experience in their lifetime. That is why labor pain relief has long been as one of the most important issues in the field of midwifery. Thus, the present study aims to explore the perception of primiparous mothers on comfortable resources for labor pain.

Clinical characteristics and mortality risk prediction in children with acute kidney injury.

Background: Acute kidney injury (AKI) is characterized by a reversible increase in the blood concentration of creatinine and nitrogenous waste products and by the inability of the kidney to regulate fluid and electrolyte homeostasis appropriately.
