The chemical and electrochemical stimuli viologen substituted phthalocyanine with tunable optical features1.

In this study, viologen-tetrasubstituted Zn(II) phthalocyanines ( and ) were designed and synthesized to achieve the tunable optical features via redox-active viologen groups. Several parameters relevant to the evaluation of the tunable optical features have been investigated: UV-Vis, cyclic voltammetry (CV), EPR, square wave voltammetry (SWV), and theoretical analyses. The results showed that upon reductions and oxidations of viologen groups either chemically or electrochemically, the optical features of and change drastically with switchable processes.

Association between thiol-disulfide hemostasis and transient tachypnea of the newborn in late-preterm and term infants.

Background: Transient tachypnea of the newborn (TTN), which is the most common respiratory disease in the neonatal period, increases respiratory workload in newborns. We purposed to evaluate the oxidative stress (OS) status and thiol disulfide hemostasis in late preterm and term newborns with TTN in this study.

Methods: The study was carried out in a single-centre neonatal intensive care unit to investigate the effect of continuous airway positive pressure (CPAP) on the oxidative system in newborns with TTN.

Evaluation of Oxidative Stress Levels and Dynamic Thiol-disulfide Balance in Patients with Retinopathy of Prematurity.

Purpose: The aim of this study is to evaluate both dynamic thiol-disulfide homeostasis and oxidative stress (OS) levels in patients with retinopathy of prematurity (ROP).

Methods: A total of 129 infants of <34 weeks gestational age were enrolled in the present study. The thiol-disulfide homeostasis was determined by using the new, cost-effective and fully automated colorimetric method.

Oxidative Stress Levels and Dynamic Thiol-Disulfide Balance in Preterm Newborns with Bronchopulmonary Dysplasia.

Objective: The aim of this study was to assess the oxidative stress (OS) levels and dynamic thiol-disulfide balance in preterm newborns with bronchopulmonary dysplasia (BPD).

Methods: This prospective study included newborns separated into 2 groups, those with BPD (case) or without BPD (control). The 2 groups were compared by clinical and laboratory findings.

Engineering the public-use reinforced concrete buildings of Ankara during the Early Republic of Turkey, 1923-1938.

Today, reinforced concrete (RC) is the most commonly used construction material in Turkey. It first emerged in Europe in the 1850s and was adopted in a number of Late Ottoman period structures, mostly in İstanbul, during the first two decades of the twentieth century. During the Early Turkish Republic (1923-1938), RC appeared in public-use buildings in Ankara, such as the Ethnographic Museum, which was the first in the new capital to feature RC elements, leading the way for many more structures to come.

"A Light Bulb in Every House": The Istanbul General Electric Factory and American Technology Transfer to Turkey.

In 1946, Turkish entrepreneur Vehbi Koç signed an agreement with the U.S. firm General Electric to build and operate its first light bulb factory in the Near/Middle East, in Istanbul.

Splenic rupture presenting with marked scrotal ecchymosis in a 2-day-old newborn.

Splenic rupture is a rare and severe condition in neonates. The signs and symptoms are vague and non-specific and are often not recognised before the onset of hypovolaemic shock or death. A 2-day-old infant presented with scrotal ecchymosis, and ultrasonography detected haemorrhage in the scrotal, right inguinal and adrenal regions.

A low direct electrical signal attenuates oxidative stress and inflammation in septic rats.

Electrical stimulation is proposed to exert an antimicrobial effect according to studies performed using bacterial and cell cultures. Therefore, we investigated the effects of electrification on inflammation in septic rats. Twenty-eight male Wistar albino rats were divided into 4 groups: healthy control (C), electrified healthy (E), sepsis (S), and electrified sepsis (SE) groups.

Variants in Two Unrelated Cases with 46, XY Disorder of Sex Development and Review of the Literature.

The genetic cause of 46, XY disorder of sex development (DSD) still cannot be determined in about half of the cases. haploinsufficiency is one of the rare causes of DSD in genetic males (46, XY). Twenty-two cases with 46, XY DSD due to haploinsufficiency (nine missense variant, two copy number variation) have been previously reported.

Risk of autism spectrum disorder in children with a history of hospitalization for neonatal jaundice.

Background: Limited research has focused explicitly on the association between neonatal jaundice and autism spectrum disorder (ASD), and inconclusive evidence exists in the literature within this framework. This study aimed specifically to investigate whether neonatal jaundice is a potential risk factor for ASD and whether there is a connection between the types of neonatal jaundice and the severity of ASD.

Methods: This study involved 119 children with ASD [90 males (75.

Clinical Management in Systemic Type Pseudohypoaldosteronism Due to Variant and Literature Review.

Systemic pseudohypoaldosteronism (PHA) is a rare, salt-wasting syndrome that is caused by inactivating variants in genes encoding epithelial sodium channel subunits. Hyponatremia, hyperkalemia, metabolic acidosis, increased aldosterone and renin levels are expected findings in PHA. Clinical management is challenging due to high dose oral replacement therapy.

An observational, prospective, multicenter study on rescue high-frequency oscillatory ventilation in neonates failing with conventional ventilation.

Background: To achieve gas exchange goals and mitigate lung injury, infants who fail with conventional ventilation (CV) are generally switched to high-frequency oscillatory ventilation (HFOV). Although preferred in many neonatal intensive care units (NICUs), research on this type of rescue HFOV has not been reported recently.

Methods: An online registry database for a multicenter, prospective study was set to evaluate factors affecting the response of newborn infants to rescue HFOV treatment.

Continuous venovenous hemodiafiltration in the treatment of newborns with an inborn metabolic disease: a single center experience.

Background/aim: Most inborn metabolic diseases are diagnosed during the neonatal period. The accumulation of toxic metabolites may cause acute metabolic crisis with long-term neurological dysfunction and death. Renal replacement therapy (RRT) modalities allow the efficient removal of toxic metabolites.
