Abstract
Listeria monocytogenes is a ubiquitous microorganism that is isolated from a variety of sources such as soil, water, decaying vegetation, sewage, animal feeds, silage, farm environments and food-processing environments. This study aimed to determine the prevalence, serogroups, biofilm formation, virulence factor genes, and genetic relationships of L. monocytogenes strains isolated from beef meat and meat contact surfaces obtained from a slaughterhouse in Burdur, Turkey. In this study, a total of 179 beef meat and meat contact surface samples were analyzed for the presence of L. monocytogenes by polymerase chain reaction (PCR). Out of a total of 179 beef meat and meat contact surface samples, 83 (46.37%) were found to be contaminated with L. monocytogenes, with the highest incidence (53.01%) occurring in beef meat. In the present study, most of the isolated strains belonged to serogroups IIB and IVB (lineage I). The L. monocytogenes strain also contained monoA-B, prfA, plcA, plcB, mpl, hlyA, actA, gtcA, dltA, Fri, flaA, InlA, InlC, InlJ, and iap genes. Biofilm formation was not determined in the tested samples at pH 5.5 and different temperatures (4°C, 10°C, 25°C, and 37°C). However, strong biofilm formation was observed in 6.45% (2/31) of the strains at pH 7.0 after 48 h incubation at 37°C, and in 3.22% (1/31) of the strains at pH 7.0 after 48 h incubation at 4°C and 10°C. Pulsed-field gel electrophoresis (PFGE) results showed that L. monocytogenes isolates were clonally related, and cross-contamination was present. In addition, PFGE results also revealed that AscI had more distinguishing power than the ApaI restriction enzyme. These results indicate that L. monocytogenes detected from meat and meat contact surfaces in the slaughterhouse pose a potential risk to public health.

Abstract
Electrical stimulation is a fundamental tool in studying neural circuits, treating neurological diseases, and advancing regenerative medicine. Injectable, free-standing piezoelectric particle systems have emerged as non-genetic and wireless alternatives for electrode-based tethered stimulation systems. However, achieving cell-specific and high-frequency piezoelectric neural stimulation remains challenging due to high-intensity thresholds, non-specific diffusion, and internalization of particles. Here, we develop cell-sized 20 μm-diameter silica-based piezoelectric magnetic Janus microparticles (PEMPs), enabling clinically-relevant high-frequency neural stimulation of primary neurons under low-intensity focused ultrasound. Owing to its functionally anisotropic design, half of the PEMP acts as a piezoelectric electrode via conjugated barium titanate nanoparticles to induce electrical stimulation, while the nickel-gold nanofilm-coated magnetic half provides spatial and orientational control on neural stimulation via external uniform rotating magnetic fields. Furthermore, surface functionalization with targeting antibodies enables cell-specific binding/targeting and stimulation of dopaminergic neurons. Taking advantage of such functionalities, the PEMP design offers unique features towards wireless neural stimulation for minimally invasive treatment of neurological diseases.

Abstract
PURPOSE We evaluated changes in ocular and periocular elasticity by ultrasound (US) elastography in intravitreal ranibizumab-treated eyes and the healthy fellow eyes of patients with neovascular AMD. METHODS The study was performed on 52 eyes of 26 volunteers who ranged in age from 59 to 89 (mean 72±7.78) years old. The study group consisted of the patients with neovascular AMD treated with intravitreal ranibizumab. The fellow eyes (without choroidal neovascularization) of the study group were selected as the control group. All patients were examined with sonoelastography before intravitreal injection and at 1day, 1week, and 1month after intravitreal injection. All images were acquired with a Toshiba Aplio 500 ultrasound system (Tokyo, Japan) including software with a combined autocorrelation method and a multifrequency linear probe. The elastography values of the anterior vitreous (AV), posterior vitreous (PV), retina-choroid-sclera complex (RCS), retrobulbar fat tissue (RF), optic nerve head (ONH) and retrobulbar optic nerve (RON) were measured in each eye. RESULTS There were 13 male (50%) and 13 female (50%) participants in our study. Anterior vitreous, posterior vitreous, RCS, retrobulbar fat tissue, ONH, and RON US elastography values were similar in both groups (P˃0.05 for all). On the other hand, there was a positive correlation between the difference between baseline and 1-month PV sonoelastography values and age (r=0.47, P=0.035). CONCLUSION A single dose intravitreal Ranibizumab (Lucentis®, Genentech, USA) injection does not alter the elasticity of ocular and periocular structures.

Abstract
Untethered magnetic miniature soft robots capable of accessing hard-to-reach regions can enable safe, disruptive, and minimally invasive medical procedures. However, the soft body limits the integration of non-magnetic external stimuli sources on the robot, thereby restricting the functionalities of such robots. One such functionality is localised heat generation, which requires solid metallic materials for increased efficiency. Yet, using these materials compromises the compliance and safety of using soft robots. To overcome these competing requirements, we propose a pangolin-inspired bi-layered soft robot design. We show that the reported design achieves heating > 70 °C at large distances > 5 cm within a short period of time <30 s, allowing users to realise on-demand localised heating in tandem with shape-morphing capabilities. We demonstrate advanced robotic functionalities, such as selective cargo release, in situ demagnetisation, hyperthermia and mitigation of bleeding, on tissue phantoms and ex vivo tissues.

Abstract
Building medical microrobots from the body's own cells may circumvent the biocompatibility concern and hence presents more potential in clinical applications to improve the possibility of escaping from the host defense mechanism. More importantly, live cells can enable therapeutically relevant functions with significantly higher efficiency than synthetic systems. Here, live immune cell-derived microrobots from macrophages, i.e., immunobots, which can be remotely steered with externally applied magnetic fields and directed toward anti-tumorigenic (M1) phenotypes, are presented. Macrophages engulf the engineered magnetic decoy bacteria, composed of 0.5 µm diameter silica Janus particles with one side coated with anisotropic FePt magnetic nanofilm and the other side coated with bacterial lipopolysaccharide (LPS). This study demonstrates the torque-based surface rolling locomotion of the immunobots along assigned trajectories inside blood plasma, over a layer of endothelial cells, and under physiologically relevant flow rates. The immunobots secrete signature M1 cytokines, IL-12 p40, TNF-α, and IL-6, and M1 cell markers, CD80 and iNOS, via toll-like receptor 4 (TLR4)-mediated stimulation with bacterial LPS. The immunobots exhibit anticancer activity against urinary bladder cancer cells. This study further demonstrates such immunobots from freshly isolated primary bone marrow-derived macrophages since patient-derivable macrophages may have a strong clinical potential for future cell therapies in cancer.

Abstract
Abstract
Aim
The recent shift from traditional surgical teaching to the incorporation of simulation training in plastic surgery has resulted in the development of a variety of simulation models and tools. We aim to identify all currently available simulators and tools for plastic surgery, assess their validity and establish their effectiveness.
Method
MEDLINE and Embase were searched for articles which validate simulation models in plastic surgery. Each study was screened in accordance with the Messick validity framework, and a rating was given for each section. In order to determine the effectiveness of each study, the McGaghie model of translational outcomes was used.
Results
On screening 2104 articles, 71 were identified to discuss validity and effectiveness. Only one study was found to achieve a high score in all validity parameters and no studies achieved an effectiveness level >2.
Conclusions
With the increasing amount of simulation training tools, there must be more validity studies conducted using updated validity frameworks. In addition, there should be an increased emphasis of the relationship between these simulators and patient outcomes/surgical technique in the operating theatre in order to determine translational outcomes. More training tools evaluating both technical and nontechnical surgical skills are recommended.

Abstract
How an organism's sensory system functions is central to how it navigates its environment. The insect olfactory system is a prominent model for investigating how ecological factors impact sensory reception and processing. Notably, work in Lepidoptera led to the discovery of vastly expanded structures, termed macroglomerular complexes (MGCs), within the primary olfactory processing centre. MGCs typically process pheromonal cues, are usually larger in males, and provide classic examples of how variation in the size of neural structures reflects the importance of sensory cues. Though prevalent across moths, MGCs were lost during the origin of butterflies, consistent with evidence that courtship initiation in butterflies is primarily reliant on visual cues, rather than long distance chemical signals. However, an MGC was recently described in a species of ithomiine butterfly, suggesting that this once lost neural adaptation has re-emerged in this tribe. Here, we show that MGC-like morphologies are widely distributed across ithomiines, but vary in both their structure and prevalence of sexual dimorphism. Based on this interspecific variation we suggest that the ithomiine MGC is involved in processing both plant and pheromonal cues, which have similarities in their chemical constitution, and co-evolved with an increased importance of plant derived chemical compounds.

Abstract
In this study, the level of arsenic (As), lead (Pb) and cadmium (Cd) and also essential elements in beer samples consumed in Turkey were investigated using the inductively coupled plasma mass spectrometry (ICP-MS) method. The heavy metal-induced non-carcinogenic and carcinogenic risks were calculated. For essential elements, the calculated estimated daily intake of iron (Fe), copper (Cu), selenium (Se) and cobalt (Co) from beer consumption were compared with their toxicity reference values. Tukey post-hoc test showed that As was found at a significantly higher level when compared to Pb. Also, a significant correlation was found between As level and alcohol by volume percent. All samples had a hazard quotient and hazard index <1, indicating no non-carcinogenic risk from exposure to single or multiple heavy metals. Some samples exceeded the threshold limit of acceptable cancer risk for As in the high beer consumer group. This assessment showed that in addition to health implications based on the alcohol content of beer, there might be a carcinogenic risk associated with the heavy metals content of these beverages.

Abstract
The effect of Jendrassik Maneuver (JM) has been extensively studied on monosynaptic reflexes in numerous muscles below the level at which the maneuver was performed. Here we hypothesize that the effect of JM could be observed also on other reflexes, indicating a widespread influence of performing a motor act such as the JM. We examined polysynaptic reflexes caudal (i.e., the withdrawal reflex of the lower extremities) and rostral (i.e., the blink reflex to supraorbital nerve stimulation) to the level of JM contraction. We have assessed soleus tendon (T) reflex; withdrawal reflex in tibialis anterior and soleus muscle; blink reflex (BR), blink reflex excitability recovery curve (BR-ER) and prepulse inhibition of the blink reflex. Our results showed that (1) T-reflex amplitude increased during JM and decreased just after and 15 min after JM; (2) no change in the withdrawal reflex; (3) R2 area of BR reduced significantly just after or 15 min after JM; (4) Prepulse inhibition in BR reduced significantly during JM; (5) no change in BR-ER. Our results indicate that JM leads to generalized effects on neural excitability at both caudal and rostral levels. Furthermore, JM has a selective effect on excitability of reflex circuitries.

Abstract
OBJECTIVE To compare the efficacy and safety of intravitreal ranibizumab (RZB) injections and intravitreal dexamethasone (DEX) implant in diabetic macular edema (DME) with concurrent epiretinal membrane (ERM). METHODS This was a retrospective, observational, comparative study. Medical records of DME patients with concurrent ERM were retrospectively reviewed. Seventeen eyes of 16 patients treated with 3 consecutive monthly RZB injections (RZB group) and 22 eyes of 18 patients treated with a DEX implant (DEX group) were included. The groups were compared at baseline, 1st, 2nd, 3rd and 4th months in terms of best-corrected visual acuity (BCVA), central macular thickness (CMT), and intraocular pressure (IOP). RESULTS Eighteen of the 39 eyes (46.1%) were phakic at baseline, 9 (52.9%) of which were treated with RZB, whereas 9 (40.9%) were treated with DEX implant (P=0.528). Although CMT improved significantly in both the RZB and DEX groups (P<0.001); the trend was different (P=0.003). The mean change in CMT at 1month in the DEX group was greater (DEX: 188.2±142.7μm; RZB: 95.7±110.7μm; P=0.034); it was in favor of RZB group at the 3rd and 4th months (DEX: -52.7±86.9μm; RZB: 1.4±31.4μm; P=0.012. DEX: -63±67.3μm; RZB: -5.8±43.9μm; P=0.004, respectively). BCVA improved significantly in both groups (P<0.001). There was no statistical difference between the groups with regard to gain in BCVA or IOP change throughout the study period (P=0.572, P=0.064, respectively). CONCLUSION Both RZB and DEX are effective in improving anatomical and visual outcomes in DME with concurrent ERM. The DEX group was associated with a prompt anatomic response, but with a gradual decrease from 3rd month.

Abstract
AIM This study aimed to culturally adapt and evaluate the reliability and validity of the Holistic Nursing Competence Scale for application in the Turkish context. BACKGROUND Nurses are expected to assess well-being of individuals by considering physical, social, psychological, cultural and spiritual dimensions to enhance adaptation to diseases. In Turkey, no tools have been developed to date for the evaluation of competencies in holistic nursing in the country. METHODS The study was conducted with 288 nurses working in two hospitals in Ankara equipped with over 500 beds. A confirmatory factor analysis was performed in order to identify whether the items and the sub-dimensions of the adapted scale complied with the original structure comprising 36 items and five sub-scales, namely 'general aptitude', 'staff education and management', 'ethically oriented practice', 'nursing care in a team' and 'professional development'. Cronbach's alpha value was used as an estimate for reliability analysis. RESULTS Opinions of 11 experts were obtained for content validation of the scale, and the content validity index was 0.90. The adaptation was observed to be acceptable on the basis of structural equation model fit indices in confirmatory factor analysis. Cronbach's alpha value was estimated to be 0.97 and 0.90, respectively, for the complete scale. CONCLUSION The study identified the Turkish version of Holistic Nursing Competence Scale as a valid and reliable tool for the evaluation of competence in holistic nursing among nurses. IMPLICATIONS FOR NURSING AND NURSING POLICY The instrument may now be utilized as a tool of measurement in nursing practice, as well as in education and research, for identifying the level of competence in the holistic nursing practices among the nurses in Turkey.

Abstract
INTRODUCTION The use of night vision goggles (NVGs) by medical staff operating in active combat areas may present a tactical advantage in maintaining unit concealment. This study seeks to assess the degree to which NVG use improves speed and ease of intravenous access in comparison to no NVG use, and which NVG system (monocular, binocular or panoramic) provides the best conditions for the clinician. METHODS Cannulation was carried out using both eyes open (BEO) and one eye open (OEO) in well-lit conditions to establish a baseline measurement. The same procedure was then performed with a variety of NVGs, with and without infrared (IR) light sources in a dark room, and the degree of difficulty, time to procedural completion and success rate were compared. RESULTS NVG use improved procedure speed in comparison to the BEO method in the dark. Among the NVG methods trialled, binocular NVG (BNVG) methods outperformed panoramic NVG (PNVG) and monocular NVG in terms of success rate. CONCLUSIONS Use of BNVG resulted with a better success rate in our study. We would like to emphasise that although combatant units prefer PNVGs for the wider temporal vision they provide, it must be kept in mind that this may pose a disadvantage in peripheral vascular access procedures while providing first aid to the casualty at close distances.

Abstract
PURPOSE To evaluate the efficacy of switching treatment from intravitreal ranibizumab to intravitreal aflibercept on the treatment of refractory macular edema secondary to central retinal vein occlusion (CRVO). METHODS In this retrospective study; 12 eyes with refractory macular edema secondary to CRVO after multiple monthly repeated intravitreal 0.5mg/0.05mL ranibizumab injections prior to switching therapy to intravitreal 2mg/0.05mL aflibercept, between March 2012 and April 2016 were reviewed. The follow-up time was 12 months. Changes in best-corrected visual acuity (BCVA), central macular thickness (CMT), central retinal volume (CRV) and injection interval between baseline and month 1, 3, 6 and 12 after switching therapy to aflibercept were reviewed and evaluated. RESULTS Mean baseline CRT decreased from 516±101 mic. to 252±114 mic. at month 12 (P=0.008). Mean baseline CRV decreased from 8.74±2.13 mm3 to 6.82±1.64 mm3 at month 12 (P=0.005). Baseline BCVA improved from 0.73±0.21 to 0.53±0.17 logMAR at month 12 (P=0.004). Mean BCVA gain was two logMar lines (10 letters) at month 12. After switching therapy to aflibercept; the mean injection interval increased significantly from 1.34 months at baseline to 1.86 months at month 12, by an increase of 0.52 months (P=0.02). CONCLUSION Intravitreal aflibercept is evaluated to be presenting significant visual and anatomical improvements in patients with persistent macular edema due to CRVO despite previous intravitreal ranibizumab.

Abstract
INTRODUCTION Cognitive training is an important training modality which allows the user to rehearse a procedure without physically carrying it out. This has led to recent interests to incorporate cognitive training within surgical education but research is currently limited. The use of cognitive training in surgery is not clear-cut and so this study aimed to determine whether, relative to a control condition, the use of cognitive training improves technical surgical skills on a ureteroscopy simulator, and if so whether one cognitive training method is superior. METHODS This prospective, comparative study recruited 59 medical students and randomised them to one of three groups: control- simulation training only (n=20), flashcards cognitive training group (n=20) or mental imagery cognitive training group (n=19). All participants completed three tasks at baseline on the URO Mentor simulator followed by the cognitive intervention if randomised to receive it. Participants then returned to perform an assessment task on the simulator. Outcome measures from the URO Mentor performance report was used for analysis and a quantitative survey was given to all participants to assess usefulness of training received. RESULTS This study showed cognitive training to have minimal effects on technical skills of participants. The mental imagery group had fewer laser misfires in the assessment task when compared to both control and flashcards group (P=.017, P=.036, respectively). The flashcards group rated their preparation to be most useful when compared to control (P=.0125). Other parameters analysed between the groups did not reach statistical significance. Cognitive training was found to be feasible and cost effective when carried out in addition to simulation training. CONCLUSION This study has shown that the role of cognitive training within acquisition of surgical skills is minimal and that no form of cognitive training was superior to another. Further research needs to be done to evaluate other ways of performing cognitive training.

Abstract
The aim of this study was to evaluate the effects of N-acetylcysteine (NAC) and desferoxamine (DFO) administered alone or in combination together in rats with doxorubicin (DOX)-induced nephrotic syndrome, by monitoring oxidative stress parameters and trace elements in renal tissue and erythrocytes. Fifty-four male Sprague-Dawley rats were included the study. Equal volume of isotonic saline was injected to control rats. After DOX administration, the animals were divided into four experimental groups: (a) rats given only DOX; (b) rats treated with NAC; (c) rats treated with DFO; (d) rats treated with NAC plus DFO. The combination of N-acetylcysteine and DFO has no beneficial effect on reducing proteinuria in experimentally nephrotic rats, although both of these agents ameliorate the condition when administered separately. It seems likely that detrimental effects of NAC plus DFO could be secondary to its effects on erythrocyte selenium levels demonstrated here. Consequently, the results may propose caution to the use of antioxidant therapeutic strategies such as NAC plus DFO against nephropathy.

Abstract
Laparoscopic surgeons perform precise and time consuming procedures while holding awkward poses in their upper body and arms. There is an ongoing effort to produce robotic tools for laparoscopic surgery that will simplify these tasks and reduce risk of errors to help both the surgeon and the patient. STIFF-FLOP is an ongoing EU FP7 project focusing on this by creating a stiffness controllable soft robotic manipulator. This paper reports on a study to test the soft manipulator's learnability and the effort associated with its use. The tests involved a limited prototype of the manipulator with a custom built test rig and EMG acquisition system. Task times and video recordings along with EMG waveforms from the forearm muscles of participants (n=25) were measured for objective assessment. A questionnaire was also provided to the participants for subjective assessment. The data shows that in average EMG levels were 25.9% less in RMS when using the STIFF-FLOP arm than when conventional laparoscopic tools were used. In terms of learnability, from the first to the second attempt on the STIFF-FLOP manipulator, elapsed time was reduced by an average of 32.1%. Further details and analysis of the EMG signals as well as time and questionnaire results is presented in the paper.

Abstract
PURPOSE The authors aimed to detect immediate risk of having high grade squamous lesions (HSIL) in atypical squamous cells of uncertain significance(AS-CUS) and concomitant high-risk human papillomavirus (HrHPV) testing as negative [HrHPV(negative)AS-CUS]. MATERIALS AND METHODS The authors performed immediate/baseline colposcopy on concomitant HrHPV (negative)AS-CUS cases. Pap tests were evaluated with liquid-based cytology (LBC) and HrHPV detection was performed in LBC material with PCR. Colposcopic diagnoses and biopsy results were compared with Pap test and HrHPV test results. RESULTS There were 104 patients over a one-year period. In all, 84 cases were included. Colposcopic biopsies revealed low grade squamous intraepithelial lesion (LSIL) in 19 cases (23%) and HSIL in three cases (4%). Intrauterine device use and smoking were significantly correlated with presence of HSIL (p = 0.005 and p = 0.007 respectively). CONCLUSION Similar data in literature, 4% of ASC-US-HrHPV (negative) cases are expected to have HSIL in follow-up periods less than six months. The present authors believe clinicians should be more open with their patients about limitations of Pap-HPV testing.

Abstract
ALC67 is an N-acylated thiazolidine compound with promising anticancer activity that led to the recent discovery of a series of 3-propionyl thiazolidine-4-carboxylic acid ethyl esters as a family of novel antiproliferative agents. Since the mutagenic and genotoxic properties of marketed anticancer molecules constitute a main issue to be addressed, this study focused on the analysis of the mutagenicity, antimutagenecity, and genotoxicity of this molecule. The mutagenicity and antimutagenicity of ALC67 were evaluated by Ames test performed on Salmonella TA98 and TA100 strains. The genotoxicity of this molecule was investigated in the chromosomal aberration assay on human lymphocytes. All results revealed that the analyzed structure is not mutagenic in the two Salmonella strains tested and was not genotoxic in human lymphocytes in vitro On the other hand, it showed a weak antimutagenic effect in these two bacterial strains. The above results indicate that after performing some more mutagenicity assays using the other recommended strains, this compound can be safely used for the development of new structures exhibiting anticancer activities.

Abstract
Paraplegia or paraparesis occurring as a complication of thoracic or thoracoabdominal aortic aneurysm repair is a well known phenomenon, but the vast majority of elective abdominal aortic aneurysm repairs are performed without serious neurological complications. Nevertheless, there have been many reported cases of spinal cord ischaemia following the elective repair of abdominal aortic aneurysms (AAA); giving rise to paraplegia, sphincter incontinence and, often, dissociated sensory loss. According to the classification made by Gloviczki et al. (1991), this presentation is classified as type II spinal cord ischaemia, more commonly referred to as anterior spinal artery syndrome (ASAS). It is the most common neurological complication occurring following abdominal aortic surgery with an incidence of 0.1-0.2%. Several aetiological factors, including intra-operative hypotension, embolisation and prolonged aortic crossclamping, have been suggested to cause anterior spinal artery syndrome, but the principal cause has almost always been identified as an alteration in the blood supply to the spinal cord. A review of the literature on the anatomy of the vascular supply of the spinal cord highlights the significance of the anterior spinal artery as well as placing additional emphasis on the great radicular artery of Adamkiewicz (arteria radicularis magna) and the pelvic collateral circulation. Although there have been reported cases of spontaneous recovery, complete recovery is uncommon and awareness and prevention remains the mainstay of treatment. However, being so tragically unpredictable and random, spinal cord ischaemia after abdominal aortic operations appears to be an unpreventable event.
