Cr and CeO promoted Ni/SBA-15 framework for hydrogen production by steam reforming of glycerol.

Ni/SBA-15 meso-structured catalysts modified with chromium and CeO (Ni-Cr-CeO/SBA-15) were utilized to produce hydrogen from glycerol steam reforming (GSR). The catalysts were synthesized by a one-pot hydrothermal process and extensively characterized by analytical techniques such as N adsorption-desorption (BET), H-temperature programmed reduction (H-TPR), powder X-ray diffraction (PXRD), inductively coupled plasma-optical emission spectrometry (ICP-OES), and transmission electron microscopy (TEM). The low-angle XRD reflections affirmed that the catalysts were crystalline and possessed a 2D-ordered porosity.

The relationship between hormonal levels and hematological parameters in cystic ovarian syndrome.

Polycystic ovarian syndrome (PCOS) is characterized by the abnormal production of ovarian androgens resulting in elevated levels of male sex hormones in women. This condition is often marked by the development of a group of small cysts, fluid-filled sacs (cysts) in the ovaries. This study aimed to analyze serum levels of prolactin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and specific hematological parameters in women with PCOS.

Dual Piezoelectric Energy Investing and Harvesting Interface for High-Voltage Input.

A novel harvesting interface for multiple piezoelectric transducers (PZTs) is proposed for high-voltage energy harvesting. Pre-biasing a PZT prior to its mechanical deformation increases its damping force, resulting in higher energy extraction. Unlike the conventional harvesters where a PZT-generated output is assumed to be continuous sinusoidal and output polarity is assumed to be alternating every cycle, PZT-generated output from human motion is expected to be random.

Age Distribution of Clinical Symptoms, Isolation, Co-morbidities and Case Fatality Rate of COVID-19 Cases in Najaf City, Iraq.

Introduction: The first case of coronavirus disease 2019 (COVID-19) in holy Najaf city in February 22, 2020. The outbreak then rose up all over Iraq from 519 cases and 20 deaths in June 2, 2020 to 3484 cases and 72 deaths per day in August 10, 2020 per 24 hours.

The Nrf2 Activator (DMF) and Covid-19: Is there a Possible Role?

Introduction: COVID-19 is a new viral illness that can affect the lungs and airways with lethal consequences leading to the death of the patients. The ACE2 receptors were widely disturbed among body tissues such as lung, kidney, small intestine, heart, and others in different percent and considered a target for the nCOVID-19 virus. S-protein of the virus was binding to ACE2 receptors caused downregulation of endogenous anti-viral mediators, upregulation of NF-κB pathway, ROS and pro-apoptotic protein.

A High-Voltage Energy-Harvesting Interface for Irregular Kinetic Energy Harvesting in IoT Systems with 1365% Improvement Using All-NMOS Power Switches and Ultra-low Quiescent Current Controller.

An energy-harvesting interface for kinetic energy harvesting from high-voltage piezoelectric and triboelectric generators is proposed in this paper. Unlike the conventional kinetic energy-harvesting interfaces optimized for continuous sinusoidal input, the proposed harvesting interface can efficiently handle irregular and random high voltage energy inputs. An N-type mosfet (NMOS)-only power stage design is introduced to simplify power switch drivers and minimize conduction loss.

Natural History of Isolated Skull Fractures in Children.

Head injury is the most common cause of neurologic disability and mortality in children. We had hypothesized that in children with isolated skull fractures (SFs) and a normal neurological examination on presentation, the risk of neurosurgical intervention is very low. We retrospectively reviewed the medical records of all children aged six to sixteen years presenting to our Level 1 trauma center with traumatic brain injuries between January 1, 2006 and December 31, 2014.

Natural history and clinical implications of nondepressed skull fracture in young children.

Background: Head injury is the most common cause of neurologic disability and mortality in children. Previous studies have demonstrated that depressed skull fractures (SFs) represent approximately one quarter of all SFs in children and approximately 10% percent of hospital admissions after head injury. We hypothesized that nondepressed SFs (NDSFs) in children are not associated with adverse neurologic outcomes.

Characterizing pilomatricomas in children: a single institution experience.

Background/purpose: Pilomatricomas, or calcifying epitheliomas of Malherbe, are among the most common superficial cutaneous soft tissue lesions in children. Familiarity with the presenting signs and symptoms allows for the diagnosis to be made on physical examination alone in most patients, avoiding expensive and unnecessary diagnostic imaging.

Methods: A retrospective IRB-approved review of surgical pathology archives and medical records of all patients undergoing excision of pilomatricomas between 1982 and 2010 was performed to determine the characteristics of the pilomatricoma tumors.

Modification of an evidence-based protocol for advanced appendicitis in children.

Introduction: We previously developed an evidence-based clinical pathway for children with advanced appendicitis. The pathway standardized the choice and duration of antibiotic therapy and established discharge criteria. Initially, the pathway led to a 50% decrease in the rate of superficial and deep surgical site infections and a significant decrease in hospital length of stay.

Evaluating the effectiveness of a discharge protocol for children with advanced appendicitis.

Background: In 2006, an evidence-based protocol for the management of children with appendicitis was established at our institution. Discharge criteria for patients with advanced appendicitis were based on a combination of clinical parameters and laboratory values. The purpose of this study is to evaluate the utility of laboratory values in guiding patient management with a discharge protocol for advanced appendicitis.

Needle core vs open biopsy for diagnosis of intermediate- and high-risk neuroblastoma in children.

Background: Open biopsy has been the mainstay for definitive diagnosis of neuroblastoma in pediatric patients. However, needle core biopsy may represent a faster, less invasive, and safer alternative to open biopsy in children. The purpose of this study was to compare safety and efficacy between needle core and open biopsy in the diagnosis of patients with intermediate- and high-risk neuroblastoma at our institution.

Esophageal bronchus in an infant--a rare cause of recurrent pneumonia.

A 4-month-old female infant presented to our institute with recurrent pneumonia and was diagnosed with a right lower lobe esophageal bronchus. This congenital anomaly is extremely rare with very few cases reported in the literature. We describe the diagnostic workup and management that led to a successful outcome.

Modified laparoendoscopic gastrostomy tube (LEGT) placement.

Purpose: The purpose of this study was to report the outcomes of our modified LEGT technique.

Methods: Charts of 26 children who underwent modified LEGT technique between May 2008 and February 2010 were retrospectively reviewed. Their age ranged from 7 days to 16 years.

Tumor volume to fetal weight ratio as an early prognostic classification for fetal sacrococcygeal teratoma.

Purpose: This study was designed to develop a prognostic factor for fetuses with sacrococcygeal teratoma (SCT) that may be useful to predict outcome and guide counseling early in pregnancy. We hypothesize that, in fetuses with SCT, the ratio of tumor size to estimated fetal weight in the second trimester predicts outcome.

Methods: We retrospectively reviewed charts of all patients evaluated at our Fetal Center for SCT between 2004 and 2009.
