Abstract
OBJECTIVE Benign Paroxysmal Positional Vertigo (BPPV) is a common vestibular disorder characterized by brief episodes of intense vertigo, often accompanied by nausea and nystagmus. The frontal QRS-T (fQRS-T) angle, a novel indicator of ventricular depolarization and repolarization heterogeneity, has garnered attention due to its potential to reveal insights into cardiac function. This study aimed to investigate the potential relationship between the fQRS-T angle and inflammation markers in individuals with BPPV. PATIENTS AND METHODS The study encompassed 49 BPPV patients and 51 healthy individuals as a control group. Laboratory assessments were conducted to measure inflammation parameters. Electrocardiogram (ECG) data was analyzed, focusing on conduction parameters including fQRS-T angle, QRS duration, QT interval, and corrected QT interval. RESULTS The study revealed that the fQRS-T angle was significantly higher in BPPV patients compared to the control group (p<.001). Moreover, inflammation markers such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), and C-reactive protein-to-albumin ratio (CAR) were notably elevated in BPPV patients (p<.001, for all). The findings of the correlation analysis demonstrated a strong association between NLR and the fQRS-T angle (r=.718, p<.001). Additionally, the results of the linear regression analysis indicated that NLR positively predicted the fQRS-T angle (p<.001). CONCLUSIONS The study's outcomes have underscored a significant increase in the fQRS-T angle among BPPV patients, suggesting altered ventricular repolarization dynamics. The strong correlation between NLR and the fQRS-T angle raises intriguing possibilities of inflammation's potential role in influencing cardiac electrophysiology. The study contributes to the growing body of evidence suggesting that BPPV might have implications beyond its immediate vestibular manifestations.

Abstract
The depletion of cellular zinc (Zn) adversely affects plant growth. Plants have adaptation mechanisms for Zn-deficient conditions, inhibiting growth through the action of transcription factors and metal transporters. We previously identified three defensin-like (DEFL) proteins (DEFL203, DEFL206 and DEFL208) that were induced in Arabidopsis thaliana roots under Zn-depleted conditions. DEFLs are small cysteine-rich peptides involved in defense responses, development and excess metal stress in plants. However, the functions of DEFLs in the Zn-deficiency response are largely unknown. Here, phylogenetic tree analysis revealed that seven DEFLs (DEFL202-DEFL208) were categorized into one subgroup. Among the seven DEFLs, the transcripts of five (not DEFL204 and DEFL205) were upregulated by Zn deficiency, consistent with the presence of cis-elements for basic-region leucine-zipper 19 (bZIP19) or bZIP23 in their promoter regions. Microscopic observation of GFP-tagged DEFL203 showed that DEFL203-sGFP was localized to the apoplast and plasma membrane. Whereas a single mutation of the DEFL202 or DEFL203 genes only slightly affected root growth, defl202 defl203 double mutants showed enhanced root growth under all growth conditions. We also showed that the size of the root meristem was increased in the double mutants compared with the wild type. Our results suggest that DEFL202 and DEFL203 are redundantly involved in the inhibition of root growth under Zn-deficient conditions through a reduction in root meristem length and cell number.

Abstract
AIMS The European Society of Cardiology (ESC) EURObservational Research Programme (EORP) Non-ST-segment elevation myocardial infarction (NSTEMI) Registry aims to identify international patterns in NSTEMI management in clinical practice and outcomes against the 2015 ESC Guidelines for the management of acute coronary syndromes in patients presenting without ST-segment-elevation. METHODS AND RESULTS Consecutively hospitalised adult NSTEMI patients (n = 3620) were enrolled between 11 March 2019 and 6 March 2021, and individual patient data prospectively collected at 287 centres in 59 participating countries during a two-week enrolment period per centre. The registry collected data relating to baseline characteristics, major outcomes (in-hospital death, acute heart failure, cardiogenic shock, bleeding, stroke/transient ischaemic attack, and 30-day mortality) and guideline-recommended NSTEMI care interventions: electrocardiogram pre- or in-hospital, pre-hospitalization receipt of aspirin, echocardiography, coronary angiography, referral to cardiac rehabilitation, smoking cessation advice, dietary advice, and prescription on discharge of aspirin, P2Y12 inhibition, angiotensin converting enzyme inhibitor (ACEi)/angiotensin receptor blocker (ARB), beta-blocker, and statin. CONCLUSION The EORP NSTEMI Registry is an international, prospective registry of care and outcomes of patients treated for NSTEMI, which will provide unique insights into the contemporary management of hospitalised NSTEMI patients, compliance with ESC 2015 NSTEMI Guidelines, and identify potential barriers to optimal management of this common clinical presentation associated with significant morbidity and mortality.

Abstract
BACKGROUND Frailty is a medical syndrome characterised by reduced physiological reserve and increased vulnerability to stressors. Data regarding the relationship between frailty and atrial fibrillation (AF) are still inconsistent. OBJECTIVES We aim to perform a comprehensive evaluation of frailty in a large European cohort of AF patients. METHODS A 40-item frailty index (FI) was built according to the accumulation of deficits model in the AF patients enrolled in the ESC-EHRA EORP-AF General Long-Term Registry. Association of baseline characteristics, clinical management, quality of life, healthcare resources use and risk of outcomes with frailty was examined. RESULTS Among 10,177 patients [mean age (standard deviation) 69.0 (11.4) years, 4,103 (40.3%) females], 6,066 (59.6%) were pre-frail and 2,172 (21.3%) were frail, whereas only 1,939 (19.1%) were considered robust. Baseline thromboembolic and bleeding risks were independently associated with increasing FI. Frail patients with AF were less likely to be treated with oral anticoagulants (OACs) (odds ratio 0.70, 95% confidence interval 0.55-0.89), especially with non-vitamin K antagonist OACs and managed with a rhythm control strategy, compared with robust patients. Increasing frailty was associated with a higher risk for all outcomes examined, with a non-linear exponential relationship. The use of OAC was associated with a lower risk of outcomes, except in patients with very/extremely high frailty. CONCLUSIONS In this large cohort of AF patients, there was a high burden of frailty, influencing clinical management and risk of adverse outcomes. The clinical benefit of OAC is maintained in patients with high frailty, but not in very high/extremely frail ones.

Abstract
Reactive oxygen species (ROS) produced by plant NADPH oxidases, respiratory burst oxidase homologs (RBOHs), play key roles in biotic and abiotic stress responses and development in plants. While properly controlled amounts of ROS function as signaling molecules, excessive accumulation of ROS can cause undesirable side effects due to their ability to oxidize DNA, lipids, and proteins. To limit the damaging consequences of unrestricted ROS accumulation, RBOH activity is tightly controlled by post-translational modifications (PTMs) and protein-protein interactions. In order to analyze these elaborate regulatory mechanisms, it is crucial to quantitatively assess the ROS-producing activity of RBOHs. Given the high endogenous ROS generation in plants, however, it can be challenging in plant cells to measure ROS production derived from specific RBOHs and to analyze the contribution of regulatory events for their activation and inactivation. Here we describe human embryonic kidney 293T (HEK293T) cells as a heterologous expression system and a useful tool to quantitatively monitor ROS production by RBOHs. This system permits the reconstitution of regulatory events to dissect the effects of Ca2+, phosphorylation, and protein-protein interactions on RBOH-dependent ROS production.

Abstract
To explore a possible recessive selective marker for future DNA-free genome editing by direct delivery of a CRISPR/Cas9-single guide RNA (sgRNA) ribonucleoprotein complex, we knocked out homologs of the Arabidopsis Multi-Antibiotic Resistance 1 (MAR1)/RTS3 gene, mutations of which confer aminoglycoside resistance, in tobacco plants by an efficient Agrobacterium-mediated gene transfer. A Cas9 gene was introduced into Nicotiana tabacum and Nicotiana sylvestris together with an sgRNA gene for one of three different target sequences designed to perfectly match sequences in both S- and T-genome copies of N. tabacum MAR1 homologs (NtMAR1hs). All three sgRNAs directed the introduction of InDels into NtMAR1hs, as demonstrated by CAPS and amplicon sequencing analyses, albeit with varying efficiency. Leaves of regenerated transformant shoots were evaluated for aminoglycoside resistance on shoot-induction media containing different aminoglycoside antibiotics. All transformants tested were as sensitive to those antibiotics as non-transformed control plants, regardless of the mutation rates in NtMAR1hs. The NtMAR1hs-knockout seedlings of the T1 generation showed limited aminoglycoside resistance but failed to form shoots when cultured on shoot-induction media containing kanamycin. The results suggest that, like Arabidopsis MAR1, NtMAR1hs have a role in plants' sensitivity to aminoglycoside antibiotics, and that tobacco has some additional functional homologs.

Abstract
BACKGROUND The relationship between stasis dermatitis (SD), clinical factors, and heart failure (HF) outcomes in outpatients has not been previously assessed. METHODS This observational cross-sectional study evaluated 324 patients admitted to the HF outpatient clinic. A total of 158 HF outpatients (100 males and 58 females) were enrolled in the study and were divided into two groups depending on whether they were diagnosed with SD within six months before attending the outpatient clinic. Forty-one patients (26 %) diagnosed with SD in the preceding six months were designated group 1, and 117 (74 %) not diagnosed were designated group 2. RESULTS Diabetes mellitus (DM) (OR =5.473, p <0.001), chronic obstructive pulmonary disease (COPD) (OR =2.623, p =0.039), and increased systolic pulmonary artery pressure (SPAP) (OR =1.061, p =0.001) values were independently associated with SD in multivariate logistic regression analysis. During the follow-up of 12 ± 4 months, no significant difference was documented between group 1 and group 2 regarding the death ratio (17 % vs. 19 %, p =0.991). In the multivariate Cox proportional-hazards model with a stepwise forward method, the presence of SD diagnosis [hazard ratio (HR) =2.933, 95 % Confidence Interval (CI): 1.660-5.181, p <0.001] and coronary artery disease (CAD) (HR=2.492, 95%CI: 1.238-5.018, p= 0.011) remained independently associated with the risk of HF-related hospitalization. CONCLUSION SD was found, for the first time, to be independently associated with DM, COPD, and increased SPAP values and determined as an independent predictor for HF-related hospitalization.HIPPOKRATIA 2022, 26 (1):13-18.

Abstract
The CRISPR/Cas9 system is now commonly employed for genome editing in various plants such as Arabidopsis, rice and tobacco. In general, in genome editing of the Arabidopsis genome, the SpCas9 and guide RNA genes are introduced into the genome by the floral dip method. Mutations induced in the target sequence by SpCas9 are confirmed after selecting transformants by screening the T1 seed population. The advantage of this method is that genome-edited plants can be isolated easily. However, mutation efficiency in Arabidopsis using SpCas9 is not as high as that achieved in rice and tobacco, which are subjected to a tissue culture step. In this study, we compared four promoters and found that the parsley UBIQITIN promoter is highly active in Arabidopsis meristem tissue. Furthermore, we examined whether a simple heat treatment could improve mutation efficiency in Arabidopsis. Just one heat treatment at 37°C for 24 h increased the mutation efficiency at all four target sites from 3 to 42%, 43 to 62%, 54 to 75% and 89 to 91%, without detectable off-target mutations. We recommend heat treatment of plate-grown plants at 37°C for 24 h as a simple method to increase the efficiency of CRISPR/Cas9-mediated mutagenesis in Arabidopsis.

Abstract
The seasonal effects on the fatty acid composition of triacylglycerol (TAG) and phospholipid (PL) in the muscle and liver of male Salmo trutta macrostigma were determined using the gas chromatographic (GC) method. The fatty acid (FA) compositions of total lipid, PL and TAG fractions were determined in muscle and liver tissues of S. trutta macrostigma. The phospholipids contained a higher proportion of 16:0 compared to the TAG in the muscle tissue of S. trutta macrostigma. Docosahexaenoic acid (22:6 ω-3) and eicosapentaenoic acid (20:5 ω-3) contents were high in both muscle and liver tissues. The total lipid contents in the muscle and liver were 1.07-2.45 and 3.00-4.64%, respectively. S. trutta macrostigma is a rich source of ω-3 and ω-6, polyunsaturated fatty acids (PUFA) with numerous benefits to human health.

Abstract
OBJECTIVES This study aims to determine the prognostic significance of the lymphocyte/mean platelet volume ratio (LMR) in terms of the clinical course of the disease in patients with COVID-19. METHODS Patients over 18 who were evaluated for COVID-19 during the period from April 1, to April 30, 2020 were retrospectively scanned. Patients with at least 1 positive PCR test result were as assigned to Group 1 while patients with negative test results were assigned to Group 2. The LMR ratio was calculated by dividing the lymphocyte value by that of MPV. The relationship between LMR, severity of patients' CT findings and 28-day mortality was evaluated. RESULTS A total of 938 patients were included in the study. It was observed that the lymphocyte and LMR levels were significantly different in those who died within 28 days (p < 0.001, p ≤ 0.001). In the ROC analysis for the LMR level, the area under the curve (AUC) was found to be 0.737 (95% CI 0.639‒0.834). When the cut‑off value of LMR was 0.045, the sensitivity was found to be 99.0 % and specificity was 15.2 %. CONCLUSION LMR can be a guide in multiple cases of care provided to critical patients, as is the case in the COVID-19 pandemic and can be used in recognizing critical patients (Tab. 5, Fig. 1, Ref. 21).

Abstract
Funding Acknowledgements Type of funding sources: None. Introduction The epidemic of pneumonia caused by a new coronavirus rapidly spread all over the world. World Health Organization called the condition as coronavirus disease 2019 (COVID-19). COVID-19 has become a life-threatening public health emergency internationally. COVID-19 mostly presents by respiratory tract symptoms including fever, dry cough, and dyspnea. The disease progression causes pneumonia and acute respiratory distress syndrome. Pathophisyology of cardiovascular effects of COVID-19 have not been well known yet. Myocardial dysfunction may occur in cytokine-originated immune reactions. Myocardial performance index (MPI) is a feasible parameter that reflects systolic and diastolic cardiac functions. Purpose We aimed to evaluate the MPI in patients with COVID-19. Methods The study consisted of 40 patients diagnosed with COVID-19 who had mild pneumonia and had not needed intensive care treatment. Transthoracic echocardiographic examination was performed in all patients at the acute stage of infection and after clinical recovery. The average time interval between the baseline and recovery echocardiography exam was about 28 ± 3,4 days. Blood samples were studied on day 0 and on days 7, 14, 21, and 28. Immunofluorescence assay was used for COVID-19 antibody titers. Respiratory secretions were sent for RT-PCR tests. Results The mean age was 54 ± 11 years ( male 26 (65% ) ). Statistically significant higher MPI (0.56 ± 0.09 versus 0.44 ± 0.07, p < 0.001), longer isovolumic relaxation time (112.3 ± 13.4 versus 91.8 ± 12.1ms, p < 0.001), longer deceleration time (182.1 ± 30.6 versus 161.5 ± 43.5ms, p = 0.003), shorter ejection time (279.6 ± 20.3 versus 298.8 ± 36.8ms, p < 0.001) and higher E/A ratio (1.53 ± 0.7 versus 1.22 ± 0.4, p < 0.001), were observed during acute period of infection compared to ones after clinical recovery. Compared with basal values, no significant change in left ventricular systolic ejection fraction was observed after clinical recovery (60.3± 3.2% versus 61.7 ± 2.4%, p > 0.05). Isovolumic contraction time was similar at acute infection and after clinical recovery ( 44.3 ± 7.8 versus 40.6 ± 9.7ms, p > 0.05) Conclusion In conclusion, our study suggests global reversible LV dysfunction in COVID-19 patients with preserved LV systolic function based on tissue Doppler derived MPI. This could be due to isolated subclinical diastolic dysfunction. To our knowledge, this study is the first echocardiographic follow-up study that evaluated the systolic and diastolic function of the left ventricle in COVID -19 patients. The underlying mechanism and its clinical significance can be established by further studies.

Abstract
Abstract
Purpose
Hyperkalemia is increasingly prevalent and life-threatening condition in heart failure (HF). In clinical practice, hyperkalemia is also an important barrier to optimal application of RAASi. New potassium binders, sodium zirconium cyclosilicate and patiromer, were developed for the treatment of hyperkalemia. TREAT HF data were analyzed for the evaluation of potential clinical application of potassium binders in real life clinical care in HF patients.
Methods
TREAT HF is a network which undertakes multicenter, national, observational studies designed to evaluate HF patients' clinical characteristics and current treatment modalities. 1028 patients with the diagnosis of chronic HF, median age 64 years and median LVEF 30% who had potassium and GFR data were included in this analysis. In this patient population, 847 patients (82.6%) were receiving beta blockers, 739 (71.9%) were receiving ACE inhibitors or ARBs and 518 (50.4%) were receiving MRA. Patients with hyperkalemia (serum potassium ≥5.1 mEq/L) were considered candidate for potassium binders based on the criteria of HARMONIZE study. According to eGFR (mL/min) level, renal dysfunction was subclassified as: stage-1 (eGFR ≥90) (n=211), stage-2 (eGFR 60-<90) (n=398), stage-3 (eGFR 30-<60) (n=306) and stage 4–5 (eGFR <30) (n=113).
Results
In study population, median potassium level was 4.5 mEq/L, median creatinin level was 1.1 mg/dL and median eGFR was 65.5 mL/min. Overall, 82.9% of patients had normal serum potassium levels (≥3.5–5 mEq/l) and 14.3% of patients (n=147) were found to have hyperkalemia (≥5.1 mEq/L) and, hypokalemia was found in 2.8% of patients (n=30). Hyperkalemia was present in 10.9% (n=23) of patients with stage-1, 12.6% (n=50) of patients with stage-2, 17.0% (n=52) of patients with stage-3 and 19.5% (n=22) of patients with stage 4–5 renal dysfunction. In patients with eGFR <60 ml/min (n=419), hyperkalemia was much more prevalent than those with eGFR ≥60 ml/min (n=609) (17.6% and 11.9% respectively, p=0.011). In patients with stage 4–5 renal dysfunction who were receiving ACEI/ARB or combination of ACEI/ARB and MRA (RAASi), more patients had hyperkalemia than those not receiving RAASi therapy (23.4%, 20.0% and 12.5%, respectively).
Conclusions
This study suggested that in real life clinical practice, 14.3% of HF patients have hyperkalemia and seem to be eligible for the treatment of potassium binders. The risk of hyperkalemia increases with advanced stages of renal dysfunction and the use of RAASi, showing an increased clinical need for potassium binders in HF patients with renal dysfunction and in those receiving RAASi.

Abstract
In the present study, we have shown the transcriptional changes in a chlorosis model transgenic tobacco plant, i-amiCHLI, in which an artificial micro RNA is expressed in a chemically inducible manner to silence the expression of CHLI genes encoding a subunit of a chlorophyll biosynthetic enzyme. Comparison to the inducer-treated and untreated control non-transformants and untreated i-amiCHLI revealed that 3568 and 3582 genes were up- and down-regulated, respectively, in the inducer-treated i-amiCHLI plants. Gene Ontology enrichment analysis of these differentially expressed genes indicated the upregulation of the genes related to innate immune responses, and cell death pathways, and the downregulation of genes for photosynthesis, plastid organization, and primary and secondary metabolic pathways in the inducer-treated i-amiCHLI plants. The cell death in the chlorotic tissues with a preceding H2O2 production was observed in the inducer-treated i-amiCHLI plants, confirming the activation of the immune response. The involvement of activated innate immune response in the chlorosis development was supported by the comparative expression analysis between the two transgenic chlorosis model systems, i-amiCHLI and i-hpHSP90C, in which nuclear genes encoding different chloroplast proteins were similarly silenced.

Abstract
BACKGROUND Unrestricted gliding of extensor and flexor tendons is essential for normal functioning of the hand. If tendon gliding is impaired, a restricted range of motion of finger joints and, finally, joint stiffness result. OBJECTIVES To answer the questions about the causes of tenodesis in the hand, which examinations are most informative, how tenolysis is technically performed, and what results can be expected. METHODS The reasons, examinations, surgical technique, and results of extensor and flexor tendon tenolysis are presented. RESULTS Based on the data in the literature tenolysis of flexor tendons leads to range of motion that is only 50-60% of the preoperative range of motion. In about 20% of patients, deterioration as serious as secondary tendon rupture is observed. Meaningful results of extensor tendon tenolysis have not yet been published. CONCLUSIONS Tenolysis of extensor and flexor tendons in the hand is a demanding surgical procedure, and in addition to detailed knowledge of anatomy and biomechanics, it requires sufficient experience-especially following the primary repair of tendon injuries. The earliest indication for tenolysis can occur at about 3 months, usually after 6 months, if continuous intensive hand therapy and splinting have not been successful. General and individual benefits and risks must be carefully weighed. The key to successful tenolysis is the patient's access to and unrestricted participation in competent postoperative treatment, ideally performed by a specialist in hand therapy, which may last for weeks or months.

Abstract
RNA-seq analysis of a transgenic tobacco plant, i-hpHSP90C, in which chloroplast HSP90C genes can be silenced in an artificially inducible manner resulting in the development of chlorosis, revealed the up- and downregulation of 2746 and 3490 genes, respectively. Gene ontology analysis of these differentially expressed genes indicated the upregulation of ROS-responsive genes; the activation of the innate immunity and cell death pathways; and the downregulation of genes involved in photosynthesis, plastid organization, and cell cycle. Cell death was confirmed by trypan blue staining and electrolyte leakage assay, and the H2O2 production was confirmed by diaminobenzidine staining. The results collectively suggest that the reduced levels of HSP90C chaperone lead the plant to develop chlorosis primarily through the global downregulation of chloroplast- and photosynthesis-related genes and additionally through the light-dependent production of ROS, followed by the activation of immune responses, including cell death.

Abstract
AIM The aim of this study was to evaluate the efficacy of trimetazidine(TMZ) after end-to-end repair in a peripheral nerve injury model. METHOD We performed end-to-end primary repair of sciatic nerves in rats and showed TMZ's regenerative effect. For this objective 30 male Sprague Dawley albino rats were used. Surgery+water group, rats were assigned to a placebo group and were given water by oral gavage. Surgery+TMZ group, rats were given trimetazidine by oral gavage. All medications were given for 12 weeks. Motor function test was performed. Afterwards, electromyography (EMG) recording was done. Finally, blood samples were taken, the animals were euthanized andsciatic nerve was removed. RESULTS The amplitudes of compound muscle action potential (CMAP) increased significantly in the Surgery+TMZ group when compared with the group that have been given Surgery+Water.

Abstract
FLOWERING LOCUS T (FT) is an essential component of florigen in Arabidopsis thaliana Transcription of FT is induced in leaves, and the resulting FT protein is transported to the shoot apex, in which it initiates floral development. Previous analyses suggest that, together with the b-ZIP transcription factor FD, FT regulates the transcription of downstream targets such as APETALA1 (AP1) in floral anlagen. However, conclusive in vivo evidence that FT is transported to the shoot apex to form an FT-FD complex is lacking. Here, using an innovative in vivo imaging technique, we show that the FT-FD complex and AP1 colocalise in floral anlagen. In addition, the FT-FD complex disappears soon after the floral transition owing to a reduction in FD transcripts in the shoot apex. We further show that misinduction of FD activity after the transition leads to defective reproductive development. Taken together, our results indicate that the FT-FD complex functions as a transient stimulus and imply that a regulatory mechanism exists during the floral transition that reduces FT-FD complex levels via modulation of FD expression.

Abstract
Reactive oxygen species (ROS) produced by NADPH oxidases, called respiratory burst oxidase homologs (Rbohs), play crucial roles in development as well as biotic and abiotic stress responses in plants. Arabidopsis has 10 Rboh genes, AtRbohA to AtRbohJ. Five AtRbohs (AtRbohC, -D, -F, -H and -J) are synergistically activated by Ca2+ -binding and protein phosphorylation to produce ROS that play various roles in planta, although the activities of the other Rbohs remain unknown. With a heterologous expression system, we found a range of ROS-producing activity among the AtRbohs with differences up to 100 times, indicating that the required amounts of ROS are different in each situation where AtRbohs act. To specify the functions of AtRbohs involved in cell growth, we focused on AtRbohC, -H and -J, which are involved in tip growth of root hairs or pollen tubes. Ectopic expression of the root hair factor AtRbohC/ROOT HAIR DEFECTIVE 2 (RHD2) in pollen tubes restored the atrbohH atrbohJ defects in tip growth of pollen tubes. However, expression of AtRbohH or -J in root hairs did not complement the tip growth defect in the atrbohC/rhd2 mutant. Our data indicate that Rbohs possess different ranges of enzymatic activity, and that some Rbohs have evolved to carry specific functions in cell growth.

Abstract
Streptococcus pyogenes Cas9 (SpCas9) is widely used for genome editing and requires NGG as a protospacer adjacent motif (PAM). Here, we show that the engineered SpCas9 (SpCas9-NGv1) can efficiently mutagenize endogenous target sites with NG PAMs in the rice and Arabidopsis genomes. Furthermore, we demonstrate that the SpCas9-NGv1 nickase fused to cytidine deaminase mediates C-to-T substitutions near the 5' end of the target sequence.

Abstract
Unrepaired DNA damage hinders the maintenance of genome integrity because it blocks the catalytic activity of replicase. The stalled replication fork can be processed through either translesion synthesis (TLS) with specific polymerases, or replication using the undamaged template. To investigate how TLS activities are regulated and how the stalled replication fork is processed in plants, reversion frequencies and homologous recombination (HR) frequencies were analyzed using GUS-based substrates. The HR frequencies in plants deficient in DNA polymerase ζ (Pol ζ) or Rev1 were higher than that in wildtype plants under normal conditions, and were significantly increased by ultraviolet light irradiation. Heat shock protein (HSP) 90 is known to be involved in various stress responses. To examine the role of HSP90 in the regulation of damage tolerance, we analyzed reversion frequencies and HR frequencies in plants grown in the presence of a HSP inhibitor, geldanamycin (GDA). Reversion frequency was lower in GDA-treated plants than in mock-treated plants. Though the HR frequency was higher in GDA-treated wildtype plants than in mock-treated plants, no significant difference was detected in Rev1-deficient plants. In yeast, TLS polymerases interacted with each other or with a replication clump component, proliferating cell nuclear antigen (PCNA). HSP90 interacted with REV1 or REV7 in Nicotiana benthamiana cells. These results suggest that HSP90 interacts with TLS polymerase(s), which promotes error-prone TLS in plants.

Abstract
Fahr's disease (striato-pallido-dentate calcifications) is a rare neurodegenerative disorder characterised by bihemispherical and symmetrical calcium deposits in certain areas of the brain, particularly in the basal ganglia. We report an unusual case of Fahr's disease in a 36-year-old man who presented with generalised seizure in our emergency department. Basing on clinical, radiological, and endocrinological aspects, the patient was diagnosed as Fahr's disease associated with hypoparathyroidism. Administration of parenteral calcium and calcitriol supplementation were started in the emergency department. The clinical outcome was favourable after the treatment. The case illustrates that Fahr's disease, though rarely seen, has to be considered in a patient with convulsive state associated with calcifications of the basal ganglia. Systematically searching for dysparathyroidism in such patients is extremely important.

Abstract
Opipramol is an antidepressant and anxiolytic drug similar in structure to tricyclic antidepressants (TCAs) but it is primarily used for the treatment of generalized anxiety disorders. Unlike many TCAs, opipramol has no reuptake-inhibiting properties. Opipramol acts as a high affinity sigma receptor agonist. Opipramol acts as a low to moderate affinity antagonist for the dopamine-2 (D2), 5-hydroxtryptamine (5-HT2), histamine 1 (H1), histamine 2 (H2), and muscarinic acetylcholine receptors accounting for its antihistamine effects, and muscarinic anticholinergic properties. Here, we report a rare case of opipramol overdose case involving a 18-year-old woman, presenting to our emergency department (ED) with loss of consciousness and wide-complex tachycardia. A firm diagnosis of opipramol overdose was made on the basis of clinical, laboratory and electrocardiogram findings.

Abstract
Introduction The purposes of this study were (a) to investigate the oxidative and antioxidative status in paediatric patients with varying severity of traumatic brain injury (TBI) during the early post-traumatic period; (b) to correlate injury severity with the oxidative and antioxidative status of patients; and (c) to identify early predictors of outcome in patients with TBI. Methods Fifty-two consecutive paediatric patients with isolated TBI and 31 age- and sex-matched healthy controls were enrolled. Patients were divided into two groups based on their Glasgow Coma Scale (GCS) scores recorded upon admission to the emergency department within the first 24 hours after injury. Twenty-three patients with moderate to severe TBI and 29 patients with mild TBI (GCS scores of >13) were included. The primary outcome variable was hospital mortality. Plasma total oxidant status (TOS), total antioxidant status (TAS), and the oxidative stress index (OSI) were assessed as predictors of early oxidative changes in serum using a novel automated measurement method. Results Compared to patients with mild TBI, TOS and OSI values were markedly elevated in patients with moderate to severe TBI. However, TAS levels did not show significant changes in either group of patients. Both GCS scores and Revised Trauma Scores were negatively correlated with the TOS and OSI, but neither was significantly correlated with the TAS. The TOS and OSI were significantly higher in non-survivors than in survivors. However, there was no significant difference in TAS levels between survivors and non-survivors. Conclusion Paediatric patients with isolated TBI are exposed to extensive oxidative stress, which varies with injury severity.

Abstract
Introduction This cross-sectional descriptive study was conducted to determine the critical thinking dispositions of emergency nurses and any influencing factors related to critical thinking. The study is considered to respond to this need and contribute to the relevant literature. Method The study was conducted with the participation of 248 emergency nurses. The study data were collected using an information form covering characteristics of the nurses and the California Critical Thinking Disposition Inventory. The data were analyzed using independent-samples t test, independent-samples one-way variance analysis (F-test), and Pearson correlation test. Results The critical thinking dispositions of the emergency nurses in the study group were found to be at medium level (246.76±23.24). It was found that the female emergency nurses had higher levels of critical thinking dispositions than that of male nurses. The emergency nurses with graduate degrees had higher levels of critical thinking dispositions than that of the nurses with other educational levels. It was demonstrated that age, marital status, experience, or participation in in-service emergency training and certificate program did not affect the critical thinking dispositions of the nurses. Conclusion The results of the study reveal that the emergency nurses who are required to make quick and correct decisions. They need to develop their critical thinking skills and further studies should be conducted with more representative sample group.

Abstract
Split-protein methods-where a protein is split into two inactive fragments that must re-assemble to form an active protein-can be used to regulate the activity of a given protein and reduce the size of gene transcription units. Here, we show that a Staphylococcus aureus Cas9 (SaCas9) can be split, and that split-SaCas9 expressed from Agrobacterium can induce targeted mutagenesis in Nicotiana benthamiana. Since SaCas9 is smaller than the more commonly used Cas9 derived from Streptococcus pyogenes, the split-SaCas9 provides the smallest tool yet for clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) plant genome editing. Both sets of split-SaCas9 (_430N/431C and _739N/740C) exhibited genome-editing activity, and the activity of split-SaCas9_739N/740C was almost the same as that of full-length SaCas9. This result indicates that split-SaCas9_739N/740C is suitable for use in targeted mutagenesis. We also show that the split-SaCas9 fragment expressed from Tomato mosaic virus could induce targeted mutagenesis together with another fragment expressed from Agrobacterium, suggesting that a split-SaCas9 system using a plant virus vector is a promising tool for integration-free plant genome editing. Split-SaCas9 has the potential to regulate CRISPR/Cas9-mediated genome editing activity in plant cells both temporally and spatially.

Abstract
Genome editing in plants becomes popular since the advent of sequence-specific nucleases (SSNs) that are simple to set up and efficient in various plant species. Although transcription activator-like effector nucleases (TALENs) are one of the most prevalent SSNs and have a potential to provide higher target specificity by their dimeric property, TALENs are sensitive to methylated cytosines that are present not only in transposons but also in active genes in plants. In mammalian cells, the methylation sensitivity of TALENs could be overcome by using a base-recognition module (N∗) that has a higher affinity to methylated cytosine. In contrast to mammals, plants carry DNA methylation at all cytosine contexts (CG, CHG, and CHH, where H represents A, C, or T) with various degrees and effectiveness of N∗ module in genome editing in plants has not been explored. In this study, we designed sets of TALENs with or without N∗ modules and examined their efficiency in genome editing of methylated regions in rice. Although improvement in genome editing efficiency was observed with N∗-TALENs designed to a stably methylated target, another target carrying cytosines with various levels of methylation showed resistance to both normal and N∗-TALENs. The results suggest that variability of cytosine methylation in target regions is an additional factor affecting the genome editing efficiency of TALENs.

Abstract
Excessive usage of the Internet can negatively affect health and health practices especially among youth. To examine the issue among Turkish students, this study determined the association between high-school students' attitudes towards Internet usage and their health behaviour. The sample (n = 2043) was randomly drawn from all students at two high schools in Turkey: one in Anatolia and one (a vocational school) in Istanbul. Data were collected using the Structured Questionnaire, Attitude Scale towards Internet Usage (ASTIU) and Adolescent Lifestyle Profile (ALP). The mean age of the students was 16.3 years, 77.7% were male and 96.9% used the Internet; mean duration of Internet use was 18.8 h/week. Female students had more positive attitudes towards Internet usage. Mean scores for ASTIU and ALP were 72.58 (SD 17.64) and 111.34 (SD 16.61) respectively, which were average levels. There was a statistically significant but weak overall negative correlation between adolescents' attitudes towards Internet usage and their health behaviour. Our results concur with studies in different cultures which suggest some negative effects, of heavy Internet use.

Abstract
CRISPR/Cas9 systems are nowadays applied extensively to effect genome editing in various organisms including plants. CRISPR from Prevotella and Francisella 1 (Cpf1) is a newly characterized RNA-guided endonuclease that has two distinct features as compared to Cas9. First, Cpf1 utilizes a thymidine-rich protospacer adjacent motif (PAM) while Cas9 prefers a guanidine-rich PAM. Cpf1 could be used as a sequence-specific nuclease to target AT-rich regions of a genome that Cas9 had difficulty accessing. Second, Cpf1 generates DNA ends with a 5' overhang, whereas Cas9 creates blunt DNA ends after cleavage. "Sticky" DNA ends should increase the efficiency of insertion of a desired DNA fragment into the Cpf1-cleaved site using complementary DNA ends. Therefore, Cpf1 could be a potent tool for precise genome engineering. To evaluate whether Cpf1 can be applied to plant genome editing, we selected Cpf1 from Francisella novicida (FnCpf1), which recognizes a shorter PAM (TTN) within known Cpf1 proteins, and applied it to targeted mutagenesis in tobacco and rice. Our results show that targeted mutagenesis had occurred in transgenic plants expressing FnCpf1 with crRNA. Deletions of the targeted region were the most frequently observed mutations. Our results demonstrate that FnCpf1 can be applied successfully to genome engineering in plants.

Abstract
Objectives We unexpectedly identified MRSA isolates carrying mecC (mecC-MRSA) from a Danish swine farm located in eastern Zealand. The objective of the present study was to investigate the origin of these isolates and their genetic relatedness to other mecC-MRSA isolates from Zealand. Methods WGS was used to infer the phylogenetic relationship between 19 identified mecC-MRSA isolates from the swine farm and 34 additional epidemiologically unrelated human isolates from the same geographical region of Denmark. Variations in the accessory genome were investigated by bioinformatics tools, and antibiotic susceptibility profiles were assessed by MIC determination. Results mecC-MRSA was isolated from a domestic swine farm, but not from cattle reared at the same farm. Phylogenetic analysis revealed that all mecC-MRSA isolates from both farm animals and workers formed a separate cluster, whereas human isolates from the same municipality belonged to a closely related cluster. Analysis of the accessory genome supported this relationship. Conclusions To the best of our knowledge, this is the first report of mecC-MRSA isolated from domestic swine. The investigation strongly indicates that transmission of mecC-MRSA has taken place on the swine farm between the farmers and swine. The close clustering of farm isolates and isolates from the same municipality suggests a local transmission of mecC-MRSA.

Abstract
The pathological effects of exposure to an electromagnetic field (EMF) during adolescence may be greater than those in adulthood. We investigated the effects of exposure to 900 MHz EMF during adolescence on male adult rats. Twenty-four 21-day-old male rats were divided into three equal groups: control (Cont-Gr), sham (Shm-Gr) and EMF-exposed (EMF-Gr). EMF-Gr rats were placed in an EMF exposure cage (Plexiglas cage) for 1 h/day between postnatal days 21 and 59 and exposed to 900 MHz EMF. Shm-Gr rats were placed inside the Plexiglas cage under the same conditions and for the same duration, but were not exposed to EMF. All animals were sacrificed on postnatal day 60 and the hearts were extracted for microscopic and biochemical analyses. Biochemical analysis showed increased levels of malondialdehyde and superoxide dismutase, and reduced glutathione and catalase levels in EMF-Gr compared to Cont-Gr animals. Hematoxylin and eosin stained sections from EMF-Gr animals exhibited structural changes and capillary congestion in the myocardium. The percentage of apoptotic myocardial cells in EMF-Gr was higher than in either Shm-Gr or Cont-Gr animals. Transmission electron microscopy of myocardial cells of EMF-Gr animals showed altered structure of Z bands, decreased myofilaments and pronounced vacuolization. We found that exposure of male rats to 900 MHz EMF for 1 h/day during adolescence caused oxidative stress, which caused structural alteration of male adolescent rat heart tissue.

Abstract
BACKGROUND The current study aimed to evaluate the influence of regular annual influenza vaccinations on cardiovascular (CV) death and heart failure-related hospitalizations (HFrH) in stable outpatients with heart failure with reduced ejection fraction. METHODS The Turkish research team-HF (TREAT-HF) is a network undertaking multicenter, observational cohort studies in HF. This study is a subgroup analysis of TREAT-HF outpatient cohorts who completed a questionnaire on influenza vaccination status and for whom follow-up data were available. A total of 656 patients with available follow-up data for CV death and HFrH including recurrent hospitalization were included in the study. Patients were classified into two groups: those who received regular influenza vaccination (40 %) and those who did not receive vaccination. RESULTS During a mean follow-up of 15 ±6 months, 113 (18 %) patients had CV death and 471 (72 %) patients had at least one HFrH. The CV death rate was similar in both groups of patients (16 vs. 19 %, p = 0.37), whereas, HFrH and recurrent HFrH were significantly less frequently encountered in patients who received regular influenza vaccination than in those who did not receive vaccination (43 vs. 92 % and 16 vs. 66 %, p < 0.001, respectively). In a multivariate Cox proportional hazards model - in addition to a few clinical factors - vaccination status (HR = 0.30, 95 % CI = 0.17-0.51, p < 0.001) and graduation from university (HR = 0.35, 95 % CI = 0.17-0.72, p = 0.004) remained independently associated with the risk of recurrent HFrH. CONCLUSION Regular influenza vaccination does not influence CV deaths; however, it decreases HFrH including recurrent episodes of HFrH in outpatients with heart failure with reduced ejection fraction.

Abstract
OBJECTIVE Carbon monoxide (CO) poisoning is very common worldwide. Despite the fact that CO is known to have cardiotoxic effects, as it has non-specific symptoms; cardiotoxicity could easily be overlooked, especially when troponin is not measured. The present study aimed to evaluate the association between troponin I levels and red cell distribution width (RDW) levels, which can be measured rapidly, easily, and affordably in the Emergency Room (ER). PATIENTS AND METHODS This single-center observational study included a total of 504 consecutive patients, who presented to the ER due to CO poisoning between January 2011 and June 2015. The diagnosis of CO poisoning was made according to the medical history and carboxyhemoglobin (COHb) level of >5%. Elevated troponin test levels, which measure >0.04 ng/ml for our laboratory, were accepted as positive. RESULTS Patients (mean age 37±14) were classified into two groups: those who had positive troponin levels (38%) and those that did not. Patients with positive troponin, who were older, had longer CO exposure time and higher creatinine, COHb and RDW levels at the index admission following CO poisoning than patients with negative troponin. In a multivariate logistic regression model with forward stepwise method, age, COHb level, CO exposure time, and RDW (HR=1.681, 95% CI: 1.472-1.934, p<0.001) remained associated with an increased risk of troponin positivity following adjustment for the variables that were statistically significant in the univariate analysis and correlated with RDW. CONCLUSIONS In patients presenting to the ER with CO poisoning, RDW can be helpful for the risk stratification of troponin positivity.

Abstract
The aim of this study was to investigate increase of QTc dispersion and P-wave dispersion during migraine attacks. Fifty-five patients (16–65 years of age, 49 women, six men) with migraine were included in our study. Heart rate, QTc interval, maximum and minimum QTc interval, QTc dispersion, maximum and minimum P-wave duration and P-wave dispersion were measured from 12-lead ECG recording during migraine attacks and pain-free periods. ECGs were transferred to a personal computer via a scanner and then used for magnification of x400 by Adobe Photoshop software. Maximum QTc interval (454 ± 24 ms vs. 429 ± 23 ms, P < 0.001), QTc interval (443 ± 26 ms vs. 408 ± 22 ms, P <0.001) and QTc dispersion (63 ± 18 ms vs. 43 ± 14 ms, P <0.001) were found significantly higher during migraine attacks compared with pain-free periods. Maximum P-wave duration (107 ± 11 ms vs. 100 ± 11 ms, P <0.001) and P-wave dispersion (45 ± 13 ms vs. 35 ± 13 ms, P <0.001) were found higher during migraine attacks than pain-free periods. We concluded that migraine attacks are associated with increased QTc and P-wave dispersion compared with pain-free periods.

Abstract
In the present study, we aimed to investigate the parameters in serum of patients with chronic lymphocytic leukaemia (CLL) and correlate with the cancer stage. The serum concentrations of ceruloplasmin, a-1-acid glycoprotein, albuminumin, transferrin, copper, zinc, manganese, and ceruloplasmin oxidase activity were measured, and compared with those from a healthy control group. The serum from 34 patients with CLL were extracted before chemotherapy. Serum transferrin, albuminumin and Zinc concentrations were lower in patients with CLL while serum a-1-acid glycoprotein, ceruloplasmin, copper concentrations, and ceruloplasmin oxidase activity were higher in CLL patients when compared with the control group. Although serum manganese concentration was lower in CLL groups than in the control group, the difference was not statistically significant. Serum transferrin concentration was lower in the early stage group compared with the advanced stage. Serum ceruloplasmin level positively correlated with serum ceruloplasmin oxidase activity in patients from the early stage group. Serum ceruloplasmin level positively correlated with serum ceruloplasmin oxidase activity in patients with advanced stage. In conclusion, increased serum ceruloplasmin oxidase activity, ceruloplasmin, a-1-acid glycoprotein, copper levels and decreased transferrin and albuminumin, unchanged manganese levels are associated with CLL and appear to be a consequence of the disease itself.

Abstract
OBJECTIVE Eosinophilic esophagitis (EoE) is diagnosed with the presence of characteristic esophageal symptoms and eosinophilic infiltration of the esophageal mucosa after other causes of eosinophilia are excluded. EoE has been reported to co-occur with some allergic diseases. In this study, we evaluated the co-existence of EoE in Ear-Nose-Throat (ENT) outpatient clinic patients with allergic rhinitis (AR). PATIENTS AND METHODS The study group consists of 67 AR patients (AR group) and the control group (CG) was formed with 53 cases with dyspepsia symptoms. Symptoms of AR and CG groups were compared in terms of endoscopic and histological findings. Moreover, in AR group, accompanying symptoms, immunoglobulin E (IgE), skin prick test (SPT) positivity, Helicobacter pylori (H. pylori) presence, endoscopic findings and biopsy results were compared between patients with EoE and those without. RESULTS Seven of the cases with AR were diagnosed with EoE. Reflux symptoms were more common in patients with EoE (71.4%). The presence of H. pylori was similar between groups. Blood IgE levels were significantly higher among EoE patients compared to those without EoE (p = 0.003). SPT positivity was present in the 85.7% of patients with EoE and 50% of the patients without EoE (p = 0.113). Allergens were more likely to be mites Dermatophagoides farinae and Dermatophagoides pteronyssinus in patients with EoE (p = 0.042 and p = 0.034 respectively). CONCLUSIONS The most common symptom among patients with EoE is reflux. In AR patients with EoE, serum IgE levels were higher compared to those without EoE. In AR patients with reflux symptoms, high serum IgE levels, and especially in patients whose tests are positive for allergy to mites, referral to a gastroenterologist for EoE evaluation may be recommended.

Abstract
The CRISPR/Cas9 system is an efficient and convenient tool for genome editing in plants. Cas9 nuclease derived from Streptococcus pyogenes (Sp) is commonly used in this system. Recently, Staphylococcus aureus Cas9 (SaCas9)-mediated genome editing was reported in human cells and Arabidopsis. Because SaCas9 (1053 a.a.) is smaller than SpCas9 (1368 a.a.), SaCas9 could have substantial advantages for delivering and expressing Cas9 protein, especially using virus vectors. Since the protospacer adjacent motif (PAM) sequence of SaCas9 (5'-NNGRRT-3') differs from that of SpCas9 (5'-NGG-3'), the use of this alternative Cas9 nuclease could expand the selectivity at potential cleavage target sites of the CRISPR/Cas9 system. Here we show that SaCas9 can mutagenize target sequences in tobacco and rice with efficiencies similar to those of SpCas9. We also analyzed the base preference for 'T' at the 6th position of the SaCas9 PAM. Targeted mutagenesis efficiencies in target sequences with non-canonical PAMs (5'-NNGRRV-3') were much lower than those with a canonical PAM (5'-NNGRRT-3'). The length of target sequence recognized by SaCas9 is one or two nucleotides longer than that recognized by SpCas9. Taken together, our results demonstrate that SaCas9 has higher sequence recognition capacity than SpCas9 and is useful for reducing off-target mutations in crop.
