Abstract
BACKGROUND Recent research indicates a prevalence of typical lung infections, such as pneumonia, in lung cancer patients. Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii stand out as antibiotic-resistant pathogens. Given this, there is a growing interest in alternative therapeutic avenues. Boron and zinc derivatives exhibit antimicrobial, antiviral, and antifungal properties. OBJECTIVES This research aimed to establish the effectiveness of ZnO and ZB NPs in combating bacterial infections in lung cancer cell lines. METHODS Initially, this study determined the minimal inhibitory concentration (MIC) and fractional inhibitory concentration (FIC) of zinc oxide nanoparticles (ZnO NPs) and zinc borate (ZB) on chosen benchmark strains. Subsequent steps involved gauging treatment success through a lung cancer-bacteria combined culture and immunohistochemical analysis. RESULTS The inhibitory impact of ZnO NPs on bacteria was charted as follows: 0.97 µg/mL for K. pneumoniae 700603, 1.95 µg/mL for P. aeruginosa 27853, and 7.81 µg/mL for Acinetobacter baumannii 19,606. In comparison, the antibacterial influence of zinc borate was measured as 7.81 µg/mL for Klebsiella pneumoniae 700603 and 500 µg/mL for both P. aeruginosa 27853 and A.baumannii 19606. After 24 h, the cytotoxicity of ZnO NPs and ZB was analyzed using the MTT technique. The lowest cell viability was marked in the 500 µg/mL ZB NPs group, with a viability rate of 48.83% (P < 0.001). However, marked deviations appeared at ZB concentrations of 61.5 µg/mL (P < 0.05) and ZnO NPs at 125 µg/mL. CONCLUSION A synergistic microbial inhibitory effect was observed when ZnO NP and ZB were combined against the bacteria under investigation.

Abstract
Multidrug-resistant bacteria is one of the most important public health problems. Increasing rates of antibacterial resistance also affect the outcomes of medical approaches. Cancer treatment because of immune system deficiency (chemotherapy or steroids usage) commonly can cause infection. Lung cancer is the dominant cause of cancer-related deaths, and infection is the most common cause of death among those patients. In this study, it was aimed to determine the antimicrobial, antibiofilm, and anticancer activity of boron compounds. A549 lung cancer cell line was infected with Acinetobacter baumannii (ATCC 19606), Klebsiella pneumoniae (ATCC 700603), and Pseudomonas aeruginosa (ATCC 27853). In order to determine the fractional inhibitory concentration (FIC) index, antibiotics and boron compound concentrations prepared according to the minimum inhibitory concentration (MIC) values were determined by the checkerboard method. In our study results, the antibiofilm activity was an average of 46% in A. baumannii+boron compounds, 45% in P. aeruginosa+boron compounds, and 43% in K. pneumoniae. Cell culture analysis results show a decrease in viability and antioxidant capacity and an increase in total oxidant status after adding boron compounds to the culture. Immunofluorescence results show a correlation with MTT, and boron compounds increased 8-OHdG expression in comparison to antibiotic administration. In conclusion, boron compounds have promising effects on bacteria, especially in resistant bacteria spp.

Abstract
This study aimed to evaluate the antibacterial activity of nine boron derivatives against biofilm-forming pathogenic bacteria. The effect of boron derivatives (CMB, calcium metaborate; SMTB, sodium metaborate tetrahydrate; ZB, zinc borate; STFB, sodium tetra fluorine borate; STB, sodium tetraborate; PTFB, potassium tetra fluor borate; APTB, ammonium pentabo-rate tetrahydrate; SPM, sodium perborate monohydrate; Borax, ATFB, ammonium tetra fluorine borate) on bacteria isolated from blood culture was determined by the minimum inhibitory concentration (MIC) method. Then, biofilm formation potentials on microplates, tubes, and Congo red agar were examined. The cytotoxicity of boron derivatives was determined by using WST-1-based methods. The interaction between the biofilm-forming bacteria, fibroblast cells, and boron derivatives was determined with the infection model. We found that the sodium metaborate tetrahydrate molecule was effective against all pathogens. According to the optical density values detected at 630 nm in microplates, meticillin-resistant Staphylococcus aureus was observed to have the most substantial biofilm ability at 0.257 nm. As a result of cytotoxicity studies, it has been determined that a 1 µg/L concentration of boron derivatives is not toxic to fibroblast L929 cells. In cell culture experiments, these boron derivatives have very serious inhibitory activity against biofilm-forming pathogens in a short treatment period, such as 2-4 h. Furthermore, using these molecules on inanimate surfaces affected by biofilms would be appropriate instead of living cells.

Abstract
OBJECTIVE Escherichia coli ST131 is a pandemic clone associated with multidrug resistance, starting with beta-lactamase production and fluoroquinolone resistance in the first place, leading to significant systemic infections. Clones that develop due to the frequency of antimicrobial resistance and the rate of spread in our country are important issues that need to be investigated. This study aims to investigate the incidence of ST131which is a "high-risk pandemic clone E. coli" in ESBL-producing and non-ESBL-producing strains, as well as their biofilm-forming abilities and antibiotic resistance rates. MATERIALS AND METHODS A total of 86 E. coli isolates were used in the study. Bacterial identifications were performed by conventional and automated methods. The double disc synergy method was used to demonstrate the presence of ESBL. Molecular studies in all E. coli strains were performed by real-time PCR method. FINDINGS 86 strains were studied, of which 83.72% were urine, 6.98% were wound, 4.65% were blood, and 2.33% were tracheal aspirate and sputum. 79.07% of these strains were ESBL-positive. 58.1% of the strains were female, whereas 41.9% were male patients, and the average age was 46.2. Out of 86 strains, 38.72% were ST131 positive, the H30 subclone was detected in 27.27% of them, and the H30-Rx subclone was detected in all of the H30 subclone positive strains. The presence of the ESBL resistance gene was detected at the rate of TEM 41.86%, SHV 37.21%, CTX-M 36.04%, and OXA 4.65%. Most commonly SHV gene (54.54%) was seen in ST131 clone-positive samples. Finally, while it was found that 48.83% of the strains formed biofilm by any method, biofilm formation was detected in 69.7% of the samples that were positive for the ST131 clone. RESULT Our study can reveal the dramatic prevalence of the ESBL-producing E. coli strains along with the high-risk ST131 clone, the dominance of the H30Rx subclone of this risky clone, as well as the importance of the influence of resistance mechanisms along with resistance and biofilm.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) infections are usually found in hospital settings and, frequently, in patients with open wounds. One of the most critical virulence factors affecting the severity and recurrence of infections is the biofilm; increasing antibiotic resistance due to biofilm formation has led to the search for alternative compounds to antibiotics. The present study aimed to use boric acid and potassium metaborate against MRSA infection in a fibroblast wound model. For this purpose, a two-part experiment was designed: First, MRSA strains were used for the test, and both boric acid and potassium metaborate were prepared in microdilution. In the second step, an MRSA wound model was prepared using a fibroblast culture, and treatments with boric acid and potassium metaborate were applied for 24 h. For the evaluation of the effects of treatment, cell viability assay (MTT assay), analysis of redox stress parameters, including total oxidant status and total antioxidant capacity analyses, lactate dehydrogenase analysis and immunohistochemical staining were performed. In addition, IL-1β and IL-10 gene expression levels were assayed. According to the results, potassium metaborate was more effective and exhibited a lower toxicity to fibroblast cells compared to boric acid; moreover, potassium metaborate decreased the level of prooxidant species and increased the antioxidant status more effectively than boric acid. The IL-1β level in the bacteria group was high; however, boric acid and potassium metaborate significantly decreased the expression levels of inflammatory markers, exhibiting the potential to improve the resolution of the lesion. On the whole, the findings of the present study suggest that boric acid and potassium metaborate may be effective on the tested microorganisms.

Abstract
PURPOSE Recent studies have revealed that growth hormone and STAT5 were related to hepatosteatosis in mice. Loss of signal transducer and activator of transcription factor-5 leads to hepatosteatosis and impaired liver regeneration. We aimed to investigate the role of IGF-1 in steatosis with normal (SNLFT) and disturbed liver function tests (SDLFT) in humans. METHODS We included 272 NAFLD patients and 110 age, sex and body mass index (BMI)-matched healty controls. We measured routine blood biochemistry and complete blood count, IGF-1, insulin, c-peptide, ferritin, hsCRP, ESR and HOMA-IR. We subdivided NAFLD patients into SNLFT and SDLFT subgroups. RESULTS ge, sex and BMI were similar between NAFLD and controls. IGF-1 levels were significantly lower in NAFLD patients (120,6±48,2) than controls (148,9±53,8), (<0,0001). IGF-1 levels were also lower in SDLFT subgroup (93,4±27,8) than SNLFT subgroup (123,1±49,0), (p:0,032). Waist circumference, fasting blood glucose, HbA1c, uric acid, hsCRP, AST, ALT, GGT, WBC, hemoglobin, hematocrit, ferritin, insulin, c-peptid and HOMA-IR measurements were significantly higher in NAFLD patients than controls (for all values: p<0,0001).Cholesterol (p:0,026), triglycerides (p<0,0001), ESR (p:0,006) were significantly higher in NAFLD patients than controls. HDL-chelesterol levels were significantly lower (p:0,002) in NAFLD patients than controls. CONCLUSION This study supported previous findings of experi-mental studies in that, IGF-1 levels were lower in SNLFT and SDLFT. Growth hormone-IGF-1 system may be involved in the pathogenesis of NAFLD.

Abstract
BACKGROUND AND AIM Acute pancreatitis (AP), an inflammatory disorder of the pancreas, is associated with significant morbidity and mortality. The pathogenesis of AP has been suggested to -involve high oxidative stress (OS), combined with inadequate antioxidant status. We aimed to investigate the levels of serum total anti-oxidant status (TAS), total oxidant status (TOS) and ischemia-modified albumin (IMA) in patients with mild AP2016. METHODS Thirty subjects with mild AP and 29 healthy controls were enrolled into the study. The levels of TAS, TOS and IMA, C-reactive protein (CRP), high sensitivity CRP (hs-CRP) and fibrinogen were measured in both groups. RESULTS TAS levels were significantly lower (p = 0.037), while IMA levels were significantly higher (p < 0.001) in patients, compared to controls. TOS levels were similar between two groups. Fibrinogen, CRP and hs-CRP levels were significantly higher in patients than those of controls (p < 0.001 for all parameters). IMA levels were positively correlated with amylase and lipase levels (r = 0.448, p = 0.001 and r = 0.469, p < 0.001, respectively). There was a negative correlation between TAS levels, and amylase and lipase levels (r = -0.277, p = 0.035 and r = -0.278, p = 0.034, respectively). CONCLUSION OS is reported to be associated with the inflammatory process and the severity of AP. In our study, among OS parameters, an increase in IMA levels and a decrease in TAS levels were observed in mild AP patients.

Abstract
AIM To investigate the benefit of using peak expiratory flow (PEF) monitoring to screen for asthma in allergic rhinitis patients. METHODS Eighty-nine consecutive patients with allergic rhinitis but never assessed for asthma were included in this prospective study. Their allergic status was determined by skin prick tests. All of the subjects filled in a questionnaire on asthma-like symptoms. If they reported such symptoms, pulmonary function tests were carried out. Then, PEF was checked twice daily for 3 weeks. RESULTS Thirty-six percent of our study group were male and 64% were female patients with a mean (SD) age of 36.3 (14.0) years. Skin prick tests were positive to grass mixture in 71 (79.8%) patients, to tree mixture in 51 (57.3%), to mite in 46 (51.7%), and to epidermal mix in 26 (29.2%) patients. Thirty-six patients (41%) reported 3 or more asthma symptoms. Lung function test results for these 36 patients showed obstruction for 11.1% (4 patients); the remaining patients (88.9%) had normal function parameters. The subjects who reported 3 or more asthma symptoms but had normal lung function monitored their PEF for 3 weeks. Sixteen (50%) patients from this group and the 4 patients with demonstrated airway obstruction had more than 20% diurnal variation in PEF. These 20 patients' asthma symptoms disappeared after they received 3 months of low-dose inhaled corticosteroid therapy. CONCLUSION It is necessary to look for asthma in patients suffering from allergic rhinitis. PEF monitoring is a low-cost, objective approach to asthma diagnosis that can be performed by a patient with allergic rhinitis even if spirometry is normal. Knowledge of this technique is of utmost importance because delay in diagnosis will result in the unsatisfactory treatment of the disease.

Abstract
Twelve patients with a median age of 75 years underwent gamma knife thalamotomy for essential tremor (ET) (n = 9) or MS-related tremor (n = 3). All 11 evaluable patients noted improvement in action tremor. Six of eight ET patients had complete tremor arrest, and the violent action tremor in all three patients with MS was improved. One patient developed transient arm weakness. Stereotactic radiosurgery for ET and MS-related tremor is safe and effective for patients who may be poor candidates for other procedures.

Abstract
OBJECT Parkinson's disease (PD) is a prevalent neurodegenerative disorder that becomes refractory to medication as the disease progresses. Although in the past 5 years increasing numbers of patients have undergone stereotactically guided posteroventral pallidotomy for advanced PD, the safety and efficacy of surgery remains to be documented. The goal in this study was to determine the potential operative morbidity and types of functional outcomes by using validated PD rating scales and a patient survey. METHODS In a prospective analysis of a consecutive surgical series the authors evaluated 58 patients with advanced PD who ranged in age from 40 to 79 years (mean 67 years) and who had undergone surgery between 1994 and 1997. They used a patient survey and the Unified Parkinson's Disease Rating Scale (UPDRS) to study patients during periods of medication administration ("on") and withdrawal ("off"; mean off score before surgery = 96). Temporary surgical morbidity was found in four patients (6.9%), three of whom developed transient dysarthria and one of whom exhibited transient confusion (1.7%). One patient had persistent dysarthria (1.7%). No patient developed a visual field deficit or sustained a brain hemorrhage. All patients were discharged from the hospital within 24 hours. Significant postsurgical improvements were noted in the UPDRS off-period total and motor scores, as well as in tremor, rigidity, bradykinesia, and contralateral dyskinesia (p < 0.005). Improvements persisted in dyskinesia and tremor for the 21 patients who were evaluated past 1 year. The authors found no improvement in any on-period symptoms except dyskinesia. Thirty-one (61 %) of 51 patients surveyed reported functional gains and/or dramatic improvement in symptoms, 17 (33%) reported symptomatic improvement without functional gains, and three (6%) had minimal or no change in symptoms. No change in the mini mental state examination score was noted during follow up. There were no significant postoperative changes in the use of medication. CONCLUSIONS In advanced PD associated with either a medically refractory state with significant off periods or levodopa-induced dyskinesias, magnetic resonance imaging-guided pallidotomy with macrostimulation was associated with minimal morbidity and yet significantly reduced dyskinesia and off-period disability. These improvements were of value to the patient and persisted beyond the 1st year.

Abstract
The proportion of patients with intractable pain successfully managed with spinal cord stimulation (SCS) remains disputed. We analyze 27 consecutive patients with intractable pain treated with SCS using identical hardware (Itrel II System; Medtronic Neurological, Inc Minneapolis, MN, USA) by a single satisfactory diagnosis 1992 through 1995. A rigid selection protocol was used: 1. A satisfactory diagnosis of the pathologic process resulting in pain was made. 2. A corrective surgical procedure was judged not feasible by surgeons experienced in the particular pathology, e.g., vascular peripheral nerve, spine. 3. Lack of satisfactory response to noninterventional pain management modalities by an interdisciplinary pain clinic. 4. Independent psychological evaluation, including a structured interview was performed by a psychologist specialized in chronic pain management. In the last eight cases, a battery of self-report tests designed to assess psychosocial and behavioral consequences of the chronic pain problem were administered as well. All cases were of nonmalignant pain, except for one patient. Thirteen cases were diagnosed with failed back surgery syndrome (FBSS), one older patient with lumbosacral radiculopathy who refused decompression, one cervical radiculopathy and Klippel-Feil syndrome, six with reflex sympathetic dystrophy (RSD), two with peripheral vascular ischemic disease, one with post-thoracotomy pain syndrome, one with leg pain following resection of angiolipoma, one with traumatic superficial peroneal neuropathy, and one with Pancoast's tumor. Fifteen patients were female and twelve were male. All were Caucasian. Their ages ranged from 27 to 84 years (mean:48). The average follow-up was 21 months (range: 48-6). All patients underwent a three day trial screening with Pisces-Quad/Resume epidural leads connected to a temporary external stimulator. An Itrel II System pulse-generator was internalized in each of the 24 patients who had successful trial (three cervical and twenty-one thoracic-lumbar). There was no morbidity. Pain reduction was sustained in 22 out of the 24 patients who continue to use the stimulator. The same number would choose to receive in an electrical stimulator again. Normalization or improvement in Quantitative Sudomotor Axon Reflex Test (Q-SART) and Thermography was documented in the patients with RSD. We conclude that rigid selection protocol can maximize the proportion of patients with intractable pain who are successfully treated with SCS. Strict neurosurgical technique eliminates infection risk. Hardware selection minimizes incidence of malfunction.

Abstract
Posteroventral pallidotomy (PVP) has received renewed interest as an ablative procedure for the symptomatic treatment of Parkinson's disease. In previous reports, the proximity of the optic tract to the lesion target in the globus pallidus internus has resulted in the occurrence of visual field deficits in as much as 14% of patients. The authors have used intraoperative visual evoked potentials (VEPs) during PVP to reduce this risk. All procedures were performed in awake patients. Flash stimuli were delivered to each eye via fiberoptic sources. Baseline flash VEPs were recorded at O1/Cz (left visual cortex to vertex), Oz/Cz (midline visual cortex to vertex), and O2/Cz (right visual cortex to vertex) for OS, OU, and OD stimulation. Epochs were acquired before and after localization, after macroelectrode stimulation, after temporary thermal lesioning, and after permanent thermal lesioning. Forty-seven patients underwent a total of 59 procedures. Visual evoked potentials were recorded reproducibly in all patients. In 11 procedures, VEP changes were reported, including six amplitude changes (10-80%), six latency shifts (3-10 msec), and one report of “variability.” In four procedures, VEP changes prompted a change in target coordinates. One false-positive and one false-negative VEP change were encountered. The only confirmed visual deficit was a superior quadrantanopsia, present on formal fields, but clinically asymptomatic. The authors conclude that VEPs may be useful for procedures performed in the awake patient because of the lack of anesthetic-induced variability. The 1.7% visual morbidity reported here (one in 59 patients) compares favorably with other series using microelectrodes. Visual evoked potentials may be a useful monitoring technique to reduce the incidence of clinically significant visual morbidity during pallidotomy, especially during formal lesioning of the ventral pallidum adjacent to the optic tract.

Abstract
We studied 45 patients who had autonomic failure with computed tomography, magnetic resonance imaging and positron emission tomography with [18F]fluorodeoxyglucose to characterize the neuroimaging features of multiple system atrophy and pure autonomic failure and determine the utility of these techniques in distinguishing multiple system atrophy from pure autonomic failure. There were 30 patients with multiple system atrophy and 15 with pure autonomic failure. In the multiple system atrophy group, eight patients had mainly cerebellar signs, seven extrapyramidal and 15 had combinations of cerebellar and extrapyramidal signs. Cerebellar atrophy on computerized tomography and magnetic resonance imaging, signal hypointensity in the posterolateral putamen on magnetic resonance imaging and a generalized reduction in glucose utilization rate with positron emission tomography with [18F]fluorodeoxyglucose, were the main findings and were seen only in the patients with multiple system atrophy. Decreased glucose utilization (hypometabolism) was most prominent in the cerebellum, brainstem, striatum and frontal and motor cortices. These results indicate clear differences, using neuroimaging studies, between multiple system atrophy and pure autonomic failure.
