Abstract
Chloride/formate exchanger (CFEX; SLC26A6) mediates oxalate transport in various mammalian organs. Studies in Cfex knockout mice indicated its possible role in development of male-dominant hyperoxaluria and oxalate urolithiasis. Rats provide an important model for studying this pathophysiological condition, but data on Cfex (rCfex) localisation and regulation in their organs are limited. Here we applied the RT-PCR and immunochemical methods to investigate rCfex mRNA and protein expression and regulation by sex hormones in the pancreas, small intestine, liver, and kidneys from intact prepubertal and adult as well as gonadectomised adult rats treated with sex hormones. rCfex cDNA-transfected HEK293 cells were used to confirm the specificity of the commercial anti-CFEX antibody. Various biochemical parameters were measured in 24-h urine collected in metabolic cages. rCfex mRNA and related protein expression varied in all tested organs. Sex-independent expression of the rCfex protein was detected in pancreatic intercalated ducts (apical domain), small intestinal enterocytes (brush-border membrane; duodenum > jejunum > ileum), and hepatocytes (canalicular membrane). In kidneys, the rCfex protein was immunolocalised to the proximal tubule brush-border with segment-specific pattern (S1=S2<S3), and both rCfex mRNA and protein expression exhibited male-dominant sex differences driven by stimulatory effects of androgens after puberty. However, urinary oxalate excretion was unrelated to renal rCfex protein expression. While the effect of male-dominant expression of rCfex in renal proximal tubules on urine oxalate excretion remains unknown, its expression in the hepatocyte canalicular membrane may be a pathway of oxalate elimination via bile.

Published: January 2019

Summary

Background
This study aimed to show the status of thioldisulphide homeostasis in essential thrombocytosis patients, which is known to play a role in platelet function.

Methods
The study included 27 ET patients and a control group of 36 healthy subjects. Serum total (–SH + –S–S–) and native (–SH) thiol levels were measured in all subjects using an automatic method.

Results
Age and gender distribution were similar in both groups. Compared with the control group, in the ET group, there were increased native thiol and total thiol levels (p = 0.001, p = 0.046). There was no correlation between thiol, total thiol and disulphide ratios with Jak2 mutation, hemorrhage and thrombosis. A positive correlation was determined between thrombosis and thiol disulphide homeostasis (p = 0.058). The study results showed that thiol-disulphide homeostasis shifted to the proliferative side in ET, in which ineffective erythropoiesis was predominant. It is also known that platelets are more active in ET cases and thiol disulphide balance is important in platelet function.

Conclusions
This result suggests that thrombotic complications may be reduced if the formation is achieved of mechanisms (oxidation mechanisms) that will trigger the increase of disulphide groups. However, more extensive research is needed on this subject.

Published: January 2019

Summary

Background
The identification of patients at higher risk of developing percutaneous transluminal angioplasty (PTA)-related complications is pivotal for achieving better clinical outcomes. We carried out a single-center, observational, retrospective study to explore whether in-hospital changes of red blood cell distribution width (RDW) may help predicting early development of PTA-related complications.

Methods
The study population consisted of all consecutive patients who underwent PTA for severe peripheral artery occlusive disease (PAOD) during a 2-year period. RDW was measured at hospital admission and discharge, and the delta was calculated. Patient follow-up was routinely performed 1-month after hospital discharge, and was based on thoughtful medical assessment and arterial ultrasonography. The control population consisted of 352 ostensibly healthy subjects.

Results
The final PTA group consisted of 224 patients. Hemoglobin was lower, whilst mean corpuscular volume (MCV) and RDW were higher in PAOD cases than in controls. Overall, 11 PAOD patients (4.9%) developed clinically significant PTA-related complications 1-month after hospital discharge. Patients who developed 1-month PTA-related complications had lower hemoglobin concentration, but higher RDW and delta RDW than those who did not. Patients with delta RDW >1 had 60% higher risk of developing 1-month PTA-related complications and 88% higher risk of developing early reocclusion. Overall, RDW exhibited an area under the curve (AUC) of 0.68 and 0.74 for predicting 1-month PTA-related complications and early reocclusion, respectively.

Conclusions
The results of this study suggest that RDW may play a role for guiding the clinical decision making of PTA patients immediately after hospital discharge.
Structural, optical and vibrational study of zinc copper ferrite nanocomposite prepared by exploding wire technique
Authors: Singh Surendra , Sahai Anshuman , Katyal S.C. , Goswami Navendu 
Published: January 2019

Abstract
We have synthesized zinc-copper ferrite (ZCFO) employing exploding wire technique (EWT). The X-ray diffraction (XRD) data confirm the formation of single phase spinel ZCFO, which is in good agreement with Fourier transform infrared spectroscopy (FT-IR), UV-Vis, and Raman spectroscopic analyses. It is also clearly seen in the SEM micrographs that the grains in ZCFO ferrite are very rough, which allows adsorption of gas like oxygen and therefore, the material can behave as active sensing surface. The size range of the grains in prepared sample is of 200 nm to 500 nm. The FT-IR spectrum of the nanocomposite consists of two broad bands, one at 580.4 cm−1 due to M–O stretching mode at the tetrahedral site and the other at 400.7 cm−1 due to M–O stretching mode at the octahedral site. The nanoparticles show a UV-Vis absorption band in the wavelength region of 400 nm to 700 nm. The energy band gap for the prepared nanomaterial was estimated to be 3.16 eV. Thus, the ferrite nanocomposite prepared by EWT is optically active. According to present literature, Raman spectroscopy study on zinc-copper ferrite system has not been reported till date. By suitable attributing various Raman modes, we have further confirmed the formation of ZCFO nanophase through the present novel approach.
Synthesis, sintering, specific heat and magnetism of Eu3S4 by low-temperature CS2-gas sulfurization of Eu2O3 nanospheres
Authors: Chen Yuqi , Li Liang , Hirai Shinji 
Published: January 2019

Abstract
Single-phase Eu3S4 was obtained via CS2 gas sulfurization of Eu2O3 nanospheres at 773 K for longer than 0.5 h. The primary particle size of Eu3S4 became larger than that of Eu2O3 during the sulfurization process. Pure synthetic Eu3S4 powders were unstable and transformed to EuS at 873 K under vacuum. Eu3S4 compacts were sintered in temperature range of 773 K to 1173 K and they transformed to EuS at 1473 K during spark plasma sintering. Specific heat of sintered Eu3S4 did not show an anomalous behavior in the range of 2 K to 50 K. The magnetic susceptibility of polycrystalline Eu3S4 followed a Curie-Weiss law from 2 K to 300 K. Magnetization of polycrystalline Eu3S4 was larger than that of single crystal Eu3S4 when the magnetic field was less than 3.5 kOe.

Published: January 2019

Abstract

Introduction
. Diabetes Control and Complications Trial has established the importance of glycemic control in reducing the progression of retinopathy, nephropathy, and neuropathy in type 1 diabetics. There is little literature linking the frequency of glycemic monitoring with glycated hemoglobin A (HbA1c) in type 2 diabetics. The objectives were to assess the influence of glycemic self-monitoring on HbA1c in three groups of patients with type 2 diabetes (with insulin, with oral antidiabetics and with combination therapy).

Methods
. The glucometer capillary surveys of 117 patients were counted in the 30 days prior to the visit to the Integrated Diabetes Unit at Centro Hospitalar Tondela-Viseu. In the three groups considered, sociodemographic characteristics (age, gender, area of residence, household and schooling) were evaluated and compared.

Results
. There was no statistically significant association between HbA1c and the frequency of capillary glucose in any of the groups. In the evaluation of sociodemographic data, contrary to what was expected, the area of residence and schooling did not influence the value of HbA1c.

Conclusion
. These results question the role of glycemic monitoring in the metabolic control of type 2 diabetics, highlighting the need to implement therapeutic education programs so that these patients can adequately intervene in the therapeutic adjustment as a function of the information obtained by capillary glycemia.

Abstract

Introduction
. Circulating autoantibodies against phospholipase A2 receptor (anti-PLA2R) are recognized as key elements in the pathogenesis of idiopathic membranous nephropathy. In current clinical practice, they are increasingly gaining attention as novel tools for diagnosis and disease monitoring. We investigated the diagnostic and prognostic utility of anti-PLA2R antibody measurements in Greek patients with biopsy-proven membranous nephropathy.

Methods
. Anti-PLA2R levels were measured in serum samples from 33 patients at diagnosis using ELISA and were associated with treatment outcome. Moreover, serial anti-PLA2R measurements were performed in 15 patients under different clinical conditions and level alterations were correlated with disease activity.

Results
. Positive anti-PLA2R antibodies at diagnosis were found in 16 of 33 patients (48.5%). Anti-PLA2R levels were independently associated with the achievement of complete remission of nephrotic syndrome after immunosuppressive treatment compared to partial remission (p = 0.02, R2 = 0.265, 95%CI -0.019 to -0.0003). Higher detectable antibody levels at diagnosis were correlated with higher proteinuria levels (r = 0.813, p = 0.0001, 95%CI 0.532 to 0.933) and lower eGFR at the end of follow-up (r = -0.634, p = 0.0083, 95%CI -0.86 to -0.202). Serial antibody measurements during follow-up showed that anti-PLA2R titers were significantly reduced at the end of treatment after complete remission was achieved, remained low under sustained clinical remission, and increased during relapse.

Conclusions
. Our findings confirm the usefulness of anti-PLA2R measurements in the diagnosis of idiopathic membranous nephropathy. Low levels of anti-PLA2R antibodies at diagnosis are predictive of complete remission of nephrotic syndrome following immunosuppressive treatment. Serial anti-PLA2R measurements correlate well with clinical status throughout the follow-up period and could be used routinely for monitoring of disease activity and treatment planning.
The Role of Health Systems in Emergency Response Planning

Abstract
The history of mankind is pervaded by many events that have had an incredible influence on the further development of civilization. Unfortunately, many historical milestones have also been marked by unimaginable disasters that have sometimes threatened the very existence of the human race. One of the most important links in the chain of readiness in emergencies and disasters is the national health system with all its institutions at the primary and secondary levels of healthcare. Their capacities and capabilities for adequate response can be significantly enhanced by the development and implementation of appropriate Emergency Response Plans (ERPs). The necessity of ERPs is considered for several important elements: to protect lives, property and the environment; to mitigate the consequences caused by emergencies and disasters and ensure the con-tinuity of general health services; to create a system and network to respond to and recover from the consequences of emergencies and disasters; to use of available resources optimally; and to provide additional resources if needed and improve the cooperation between sectors and agencies. The overall quality of a healthcare system is also measured by its readiness to respond to mass casualty events, emergencies and disasters. The lack of an ERP, a poor ERP, or a nonunderstandable or inaccessible plans leads to partial preparedness that can cause unimaginable consequences to overall health and loss of life of the population.
Oral Disorders in Sjögren’s Syndrome
Authors: Gobeljic Mirjana Sijan , Milic Vera , Pejnovic Nada , Damjanov Nemanja 
Published: January 2019

Abstract
Sjögren’s syndrome (SS) is a complex, chronic, systemic, autoimmune disease that mainly affects the exocrine glands, especially the salivary and lacrimal glands, leading to the dryness of the mouth and eyes, along with fatigue, joint and muscle pain. The prevalence of SS is estimated to be between 0.05% and 1% in European population. Diagnosis of SS is based on the revised criteria of the American-European consensus group (AECG). Sjögren’s syndrome can be subclassified into primary disease (primary Sjögren syndrome, pSS) and a secondary disease (secondary Sjögren syndrome, sSS) when present with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE) and systemic sclerosis. The decrease in salivary flow and qualitative alterations in saliva could explain many of the oral manifestations frequently present in patients with SS. Low salivary flow may affect chewing, swallowing, speech and sleeping in pSS patients. Oral manifestations include dental erosion, dental caries, mucosal infection, ulcers and oral candidiasis. Recent studies reveal that pSS patients experience impaired olfactory and gustatory functions and have higher occurrence of oral complications such as dysgeusia, burning sensation in the tongue (BST) and halitosis. The exocrine manifestations and systemic involvement in SS significantly impact the patient’s perception of oral healthrelated quality of life (OHRQoL).
