Investigation of climate-quality relationship in bread wheat (T. aestivum L.) by novel statistical approach (ESOGÜ quality index).

In this study, precipitation; temperature (maximum, minimum, and average temperature) values of Eskisehir, Konya, Afyonkarahisar, Usak, and Kütahya for years (2007-2018); and protein content, macro sedimentation (MSDS), thousand kernel weight (KW), test weight (TW) relations, and the effect of climate values on quality were investigated. The Kriging method was used by ArcGIS software for creating quality maps of Eskisehir, Konya, Afyonkarahisar, Usak, and Kütahya provinces in the light of obtained data from these examined quality criteria, yield, and climate factors. The quality of bread wheat, which includes protein content, macro sedimentation, thousand kernel weight, and test weight, is highly affected by the subject precipitation, maximum temperature, minimum temperature, average temperature, and precipitation. While the months of November, March, and April and the total annual precipitations affect the quality, the most effective precipitation is the months of April and November. Again, the fact that the winter months are hot, especially in January and February, causes the plant to be inadequate to withstand the winter, causing the plant to be more affected by the low temperatures in the early spring and to reduce the quality due to insufficient plant growth. Climatic factors affect quality in total, not alone, but cumulatively. It was concluded that the best quality wheat can be obtained from Konya, Eskisehir, and Afyonkarahisar provinces. It was concluded that ESOGÜ quality index (EQI), evaluating and integrating protein content, macro sedimentation, thousand kernel weight, and test weigh together, can be used safely in bread wheat genotypes.

New bis- and tetrakis-1,2,3-triazole derivatives: Synthesis, DNA cleavage, molecular docking, antimicrobial, antioxidant activity and acid dissociation constants.

In this study, a series of bis- and tetrakis-1,2,3-triazole derivatives were synthesized using copper-catalyzed azide-alkyne cycloaddition (CuAAC) click chemistry in 73-95% yield. The bis- and tetrakis-1,2,3-triazoles exhibited significant DNA cleavage activity while the tetrakis-1,2,3-triazole analog 6g completely degraded the plasmid DNA. Molecular docking simulations suggest that compound 6g acts as minor groove binder of DNA by binding through several noncovalent interactions with base pairs. All bis- and tetrakis-1,2,3-triazole derivatives were screened for antibacterial activity against E. coli, B. cereus, S. aureus, P. aeruginosa, E. hirae, L. pneumophila subsp. pneumophila strains and antifungal activity against microfungus C. albicans and C. tropicalis strains. Compound 4d exhibited the best antibacterial activity among bis-1,2,3-triazoles against E. coli and E. hirae, while 6c exhibited the best antibacterial activity among tetrakis-1,2,3-triazoles against E. hirae. Furthermore, the best antifungal activity against C. albicans and C. tropicalis was reported for the compound 5, while 6d displayed the best antifungal activity against C. tropicalis and C. albicans. Reasonable iron chelating activities and DPPH radical scavenging abilities were found for some of the compounds. Finally, the acid dissociation constants (pKa) of the bis-1,2,3-triazoles were also determined with the help of HYPERQUAD program using the data obtained from potentiometric titrations. The reported data here concludes that the bis- and tetrakis-1,2,3-triazoles are important cores that should be considered for further development of especially new anticancer agents acting through the DNA cleavage activity.

Is Perioperative Antibiotic Necessary in Straightforward Implant Placement Procedures?

The purpose of this nonrandom retrospective cohort study was to evaluate the impact of perioperative antibiotic on early outcomes, including postoperative pain, swelling, bleeding, and cyanosis, in patients undergoing dental implant placement before prosthetic loading. Seventy-five patients (45 men, 30 women) who had completed dental implant placement were included in the study. Patients who used perioperative antibiotics comprised the experimental group, and those who did not comprised the control group. The experimental group received 2 g amoxicillin + clavulanic acid 1 hour before surgery and 1 g amoxicillin + clavulanic acid twice a day for 5 days after surgery. The control group received no perioperative antibiotic therapy. Data on pain, swelling, bleeding, cyanosis, flap dehiscence, suppuration, and implant failure were analyzed on postoperative days 2, 7, and 14 and at week 12. No statistically significant difference was detected between the 2 groups with regard to pain and swelling on postoperative days 2, 7, and 14 and week 12 (P > .05), while the severity of pain and swelling were greater on day 2 than on days 7 and 14 and week 12 in both groups (P = .001 and P < .05, respectively). Similarly, no significant difference was found between the 2 groups with regard to postoperative bleeding and cyanosis. Although flap dehiscence was more severe on day 7 in the experimental group, no significant difference was found between the 2 groups with regard to the percentage of flap dehiscence assessed at other time points. Within the limitations of the study, it has been demonstrated that antibiotic use has no effect on implant failure rates in dental implant surgery with a limited number of implants. We conclude that perioperative antibiotic use may not be required in straightforward implant placement procedures. Further randomized controlled clinical studies with more patients and implants are needed to substantiate our findings.

Synthesis, biological properties, and acid dissociation constant of novel naphthoquinone-triazole hybrids.

A series of novel 1,4-naphthoquinone-triazole hybrids, N-(3-amino-1,4-dioxo-1,4-dihydronaphthalen-2-yl)-2-(4-R-1H-1,2,3-triazol-1-yl)acetamide, was synthesized by click chemistry in the presence of sodium ascorbate and copper(II) sulfate pentahydrate in 81-94% yield. Various biological properties of the synthesized compounds including DNA binding/cleavage, antioxidant, antibacterial and antifungal properties were evaluated. The DNA binding study was performed using dsDNA and G-quadruplex DNA. All of the compounds showed fluorescence increase in the presence of DNA, regardless of the structure. Up to 2.9 and 2.5 times fluorescence increase upon incubation with double stranded or G-quadruplex DNA was detected for 5f and 5g, respectively. The docking studies performed on dsDNA and G-quadruplex structures suggested compounds' mode of interactions were populated around the grooves. All of the compounds showed excellent DNA cleavage activity and 5e was almost degraded the plasmid DNA. The highest radical scavenging activity was obtained as 89.9% at 200 mg/L with 5d. However, the highest ferrous chelating activity was obtained as 68.1% at 200 mg/L with 5g. The compounds exhibited antimicrobial activity against Bacillus cereus, Legionella pneumophila subsp. pneumophila, Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Enterococcus hirae as bacteria strains and Candida albicans and Candida tropicalis as microfungus strains. The compounds exhibited antibacterial and antifungal activity in the range of 4-128 µg/mL and 16-128 µg/mL, respectively. The best antimicrobial activity was obtained with 5d and 5e with a MIC value of 4 µg/mL against Enterococcus hirae. The acid dissociation constants (pKa) were determined potentiometrically in 20% (v/v) dimethyl sulfoxide-water hydro-organic solvent at an ionic background of 0.1 mol/L of NaCl, at 25 ± 0.1 °C. Five pKa values were obtained for each ligand.

The lesion commonly affects the maxilla of infants during the first year of life. Common treatment methods include surgical excision and resection of the tumor. The aim of this article is to present the diagnosis and treatment of a patient with melanotic neuroectodermal tumor that occurred in the anterior maxilla of a 6-month-old male baby.

Encrusted cystitis caused by corynebacterium urealyticum: a case report with novel treatment strategy of intravesical dimethyl sulfoxide.

Encrusted cystitis (EC) was first described as chronic cystitis with mucosal calcification in 1914 (1). It is a very rare chronic inflammatory disease presenting with dysuria, pelvic pain and gross hematuria. Voided urine contains mucus or calcified mucopurulent stone like particles. Urinalysis always reveals alkaline pH. It may be present in healthy individuals with no predisposing etiological factors (2-4). Etiologically, previous urological diseases, immunosuppression, urinary infection with urea splitting bacteria, or urological interventions resulting in bladder mucosa trauma may also be present (5, 6). In the present case report, we describe a novel treatment for EC with intravesical dimethyl sulfoxide.

A comparison of early clinical outcomes of off-pump and on-pump coronary artery bypass grafting surgery in elderly patients.

BACKGROUND: The reply of question of "which coronary artery bypass grafting (CABG) technique is superior in elderly patients, off-pump or on-pump CABG surgery?" is controversial. We aimed to compare the early clinical outcomes in elderly patients undergoing off-pump and on-pump CABG. METHODS: From January 2009 to January 2015, 344 elderly patients (aged 70 or older) underwent off-pump (n = 137) or on-pump (n = 207) CABG. Patients' medical records were retrospectively reviewed, and their baseline preoperative characteristics, operative data and postoperative outcomes were analyzed, thereby a comparison of early outcomes between off-pump and on-pump patients was performed. RESULTS: Mean age of patients was 74.4 ± 3.8 years. Both groups were statistically similar in terms of baseline preoperative characteristics. Number of distal bypass was significantly lower in off-pump group than in on-pump group. Postoperative length of intensive care unit and hospital stay were similar between two groups. Amounts of transfused blood products were significantly lower in off-pump CABG group. There were no significant differences in terms of postoperative complications and mortality between two groups. CONCLUSIONS: Our results did not reveal a significant benefit of either surgical technique with respect to early-term clinical outcomes in elderly CABG patients. Further investigations are needed to determine whether off-pump CABG is superior than on-pump CABG in elderly patients.

ACP-ESM: A novel framework for classification of anticancer peptides using protein-oriented transformer approach.

Anticancer peptides (ACPs) are a class of molecules that have gained significant attention in the field of cancer research and therapy. ACPs are short chains of amino acids, the building blocks of proteins, and they possess the ability to selectively target and kill cancer cells. One of the key advantages of ACPs is their ability to selectively target cancer cells while sparing healthy cells to a greater extent. This selectivity is often attributed to differences in the surface properties of cancer cells compared to normal cells. That is why ACPs are being investigated as potential candidates for cancer therapy. ACPs may be used alone or in combination with other treatment modalities like chemotherapy and radiation therapy. While ACPs hold promise as a novel approach to cancer treatment, there are challenges to overcome, including optimizing their stability, improving selectivity, and enhancing their delivery to cancer cells, continuous increasing in number of peptide sequences, developing a reliable and precise prediction model. In this work, we propose an efficient transformer-based framework to identify ACPs for by performing accurate a reliable and precise prediction model. For this purpose, four different transformer models, namely ESM, ProtBERT, BioBERT, and SciBERT are employed to detect ACPs from amino acid sequences. To demonstrate the contribution of the proposed framework, extensive experiments are carried on widely-used datasets in the literature, two versions of AntiCp2, cACP-DeepGram, ACP-740. Experiment results show the usage of proposed model enhances classification accuracy when compared to the literature studies. The proposed framework, ESM, exhibits 96.45% of accuracy for AntiCp2 dataset, 97.66% of accuracy for cACP-DeepGram dataset, and 88.51% of accuracy for ACP-740 dataset, thence determining new state-of-the-art. The code of proposed framework is publicly available at github (https://github.com/mstf-yalcin/acp-esm).

Natural Radioactivity Levels of the Beach Sands of Cleopatra Beach and Damlatas Beach (Türkiye) and Their Impact on Human Health.

HPGe γ spectrometry method was used to measure the natural radioactivity levels (40K, 232Th, and 226Ra) of the beach sand samples from Cleopatra Beach and Damlatas Beach in Antalya (Türkiye). The mean 40K, 232Th, and 226Ra radioactivity levels of the studied samples were calculated as 276.88 ± 17.24, 25.04 ± 2.88, and 17.06 ± 1.68 Bq/kg, respectively. Being below the radiation limits, these values indicate no risk in terms of public health. Moreover, the radiological risk parameters, such as excess lifetime cancer risk, radium equivalent activity (Raeq), absorbed γ dose rate (D), annual effective dose equivalent (Eaed), γ index (Iγ), internal radiation hazard index (Hin), and external radiation hazard index (Hex), were calculated. The values of all of these parameters were found to be below the internationally accepted radiation limit values. In addition, distribution maps showing the radiological situation of the region were generated although they did not pose a hazard to public health. No results were found in the analysis processes related to artificial radioactivity.

Biological Performance of Hexadeca-Substituted Metal Phthalocyanine/Reduced Graphene Oxide Nanobioagents.

This study presents a tetra-substituted phthalonitrile derivative, namely, diethyl 2-(3,4-dicyano-2,5-bis(hexyloxy)-6-(4-(trifluoromethoxy)phenoxy)phenyl)malonate (a), cyclotetramerizing in the presence of some metal salts. The resultant hexadeca-substituted metal phthalocyanines [M= Co, Zn, InCl)] (b-d) were used for the modification of reduced graphene oxide for the first time. The effect of the phthalonitrile/metal phthalocyanines on biological features of reduced graphene oxide (rGO) was extensively examined by the investigation of antioxidant, antimicrobial, DNA cleavage, cell viability, and antibiofilm activities of nanobioagents (1-4). The results were compared with those of unmodified rGO (nanobioagent 5), as well. Modification of reduced graphene oxide with the synthesized compounds improved its antioxidant activity. The antioxidant activities of all the tested nanobioagents also enhanced as the concentration increased. The antibacterial activities of all the nanobioagents improved by applying the photodynamic therapeutic (PDT) method. All the phthalonitrile/phthalocyanine-based nanobioagents (especially phthalocyanine-based nanocomposites) exhibited DNA cleavage activities, and complete DNA fragmentation was observed for nanobioagents (1-4) at 200 mg/L. They can be used as potent antimicrobial and antimicrobial photodynamic therapy agents as well as Escherichia coli microbial cell inhibitors. As a result, the prepared nanocomposites can be considered promising candidates for biomedicine.

The usefulness of transcervical ultrasonography for the prediction of obstructive sleep apnea in children.

OBJECTIVE: It was aimed to investigate the role of tonsil ultrasonography(USG) in the diagnosis of pediatric OSAS. METHODS: Before tonsillectomy (±adenoidectomy) for OSAS, all patients tonsil USG and polysomnography (PSG) tests were performed. Tonsil volume was measured preoperatively with the Brodsky tonsil grading scale and by postoperative water displacement test. RESULTS: In total, 47 patients were included in the study. We observed a positive correlation between tonsil volumes measured by preoperative USG and water displacement test postoperatively. There was a statistically significant correlation between tonsil sizes measured by tonsil USG, PSG AHI and questionnaire scores(p < .05). CONCLUSION: Preoperative tonsil USG may be helpful test in children with suspected OSAS.

The investigation of cognition, proprioception, sensory and physical function in stroke patients with urinary incontinence.

PURPOSE: This study aimed to investigate cognition, proprioception, and sensory/physical function in stroke patients with urinary incontinence (UI). METHODS: A prospective cross-sectional study was conducted on 53 individuals with stroke (23 had UI and 21 matched controls). The Incontinence Impact Questionnaire Short Form (IIQ-7) and Urogenital Distress Inventory (UDI-6) were used to assess the patients' UI symptoms. Participants were also evaluated with Mini-Mental State Examination (MMSE), Barthel Index (BI), Fugl-Meyer Sensory Assessment (FMA-S), Five Times Sit to Stand Test (FTSST), Functional Reach Test (FRT) and Proprioception Test. RESULTS: FTSST, FRT and FMA-S were better in stroke subjects without UI (p < 0.05). There was a moderate correlation between IIQ-7 with FMA-S, FTSST and proprioception (left extremity) (r1: - 0.415, r2: 0.440, r3: 0.430, p < 0.05) and a low correlation with BI (r: - 0.356, p < 0.05). CONCLUSION: Individuals with UI had worse sensory/motor function and static balance. Stroke patients with UI were more dependent, had less sensory function, and had worse lower extremity muscle strength and proprioception as the level of urinary incontinence increased. To reduce urinary incontinence, emphasis on motor/sensory function, balance, and proprioception should be considered.

Advances in the Elemental Composition Analysis of Propolis Samples from Different Regions of Turkey by X-Ray Fluorescence Spectrometry.

In this study, it was aimed to determine the elemental composition of 47 propolis samples collected from different regions of Turkey by X-ray fluorescence spectroscopy. According to the results, the most abundant elements in propolis samples were the Ca, K, and Si with the mean values as 1556, 1383, and 731 mg/kg, respectively. Additionally, there were high degrees of positive and strong correlations of Al with S (0.925) and Fe (0.926) and Ca with Mg (0.970). According to cluster analysis results, the Aegean, Marmara, and Mediterranean regions showed strong similarities, whereas Southeastern Anatolia propolis samples were remarkably different. The elements considered as toxic for human and environmental health such as Mn, Ni, Pb, Sn, and W were at the trace amounts as < 10 mg/kg. When assuming 1 g raw propolis is consumed daily by a 60-kg adult, the analyzed propolis samples were not a source carrying the negative effects of these elements. However, they could be an indicator of environmental pollution.

Spatial geochemical structure of soft sediment on shallow littoral of the Gulf of Antalya, the eastern Mediterranean Sea.

The concentrations of heavy metals in soft sediments of the Manavgat and Lara regions in Antalya, Türkiye were investigated to assess contamination levels and their potential sources, followed by multivariate statistical analysis and generation of spatial distribution maps. Results showed low contamination levels for As, Zn, and Cu, moderate contamination for Pb, Ni, and Mn, and very high accumulation for Co and Cr. Geoaccumulation index (Igeo) and contamination factor (CF) analyses revealed moderate enrichment for Mn and low enrichment for As, indicating no human-induced contamination in Cu, Pb, Zn, Mn, and As, while Ni, Co, and Cr originated mainly from agriculture. The maximum modified degree of contamination (mCd) value was at an extreme high level, with an average mCd of 4.12 indicating high contamination. Maximum pollution load index (PLI) value was 3.13, indicating high-grade pollution and an average value of 1.7 indicating moderate pollution.

Oxidative stress in vivax malaria.

Malaria is still a leading cause of morbidity and mortality. The increase in lipid peroxidation reported in malaria infection and antioxidant status may be a useful marker of oxidative stress during malaria infection. The aim of this study was to investigate the role of antioxidant enzymes against toxic reactive oxygen species in patients infected with Plasmodium vivax and healthy controls. Malondialdehyde levels, superoxide dismutase, and glutathione peroxidase activities were determined in 91 P. vivax patients and compared with 52 controls. Malondialdehyde levels, superoxide dismutase, and glutathione peroxidase activities were 8.07±2.29 nM/ml, 2.69±0.33 U/ml, and 49.6±3.2 U/g Hb in the patient group and 2.72±0.50 nM/ml, 3.71±0.47 U/ml, and 62.3±4.3 U/g Hb in the control group, respectively. Malondialdehyde levels were found statistically significant in patients with vivax malaria higher than in healthy controls (P<0.001). On the other hand, superoxide dismutase and glutathione peroxidase activities were found to be significantly lower in vivax malaria patients than in controls (P<0.05). There was an increase in oxidative stress in vivax malaria. The results suggested that antioxidant defense mechanisms may play an important role in the pathogenesis of P. vivax.

Evaluation of different fixation methods with finite element analysis in total mandibular subapical osteotomy.

PURPOSE: The purpose of the study was to evaluate the stress distribution in various miniplates that were used in cases that underwent advancement with total mandibular subapical osteotomy (TMSO) using finite element analysis (FEA). MATERIAL AND METHOD: Cone beam computed tomography (CBCT) images of a patient with appropriate bone tissues were used as a reference for the modeling of the mandible. In all mandibular models, horizontal TMSO was performed in a region 5 mm away from the apex of the teeth and vertical TMSO was performed in the retromolar region, 10 mm posterior to the second molar tooth. After TMSO, the dentoalveolar segment was advanced 3 mm and miniplates were placed symmetrically at four points for fixation. Four different miniplates with 2.0 mm thickness were used. Three different forces were applied to the models. Stress distribution on the models was evaluated using maximum von Mises stress values. RESULTS: The maximum von Mises stress occurred in Y + I and Y + L models following the application of 300 N force from the incisal. An evaluation of posterior unilateral force indicated that the stress was remarkably high in the models with a posterior I-plate. The stress in the Y + I model was higher under unilateral force compared to the stress in other models. Under posterior bilateral force, the maximum von Mises stress values ​​occurred in the I-plates of T + I, Y + I, and L + I models (1006, 1012, and 1004 MPa, respectively). CONCLUSION: Within the limitations of our study, we found that the ideal stress distribution was in the T + L and L + L plate combinations in the plates used for fixation after advancement with TMSO.

Multicolor Emitting Carbon Dot-Reinforced PVA Composites as Edible Food Packaging Films and Coatings with Antimicrobial and UV-Blocking Properties.

Active food packaging has become attractive because of the possibility to provide a longer shelf-life by loading functional agents into the packages to maintain the quality of food products. Herein, photoluminescent and transparent polyvinyl alcohol (PVA)-based composites embedding multicolor fluorescent carbon dots (CD/PVA) were prepared by the solvent casting method. The prepared CDs emit a strong and stable fluorescence in solution while the CD/PVA composite films were transparent, flexible, and showed UV-blocking activity with a strong fluorescence emission. Blue color-emitting CDs showed the highest UV blockage at UVA (87.04%), UVB (87.04%), and UVC (92.22%) regions while PVA alone absorbed only less than 25% of the light in all UV regions. UV blockage capacity was shown to be decreased by half, in line with the emission color shift from blue to red. Thermal properties of the PVA film were improved by the addition of CDs to the polymer, and in vitro cell viability tests showed that none of the CDs were cytotoxic against the human lung fibroblast healthy cell line (MRC-F cells) when integrated into the PVA. The antimicrobial activity of CD/PVA nanofilms was qualitatively determined. The prepared films exhibited good antimicrobial activity against both Gram-positive and Gram-negative bacteria with mild antioxidant and metal chelating activity, and significant inhibition of biofilm formation with a strong link with emitted color and the concentration of the composites. Green- and red-emitting CD/PVA with the highest antimicrobial activity were then analyzed and compared with the plane PVA employing their effect on the shelf-life of strawberries as a model for perishable foods. Fresh strawberries dip coated with CD/PVA and PVA were monitored over time, and virtual evaluations showed that CDs/PVA film coating resulted in reduced weight and moisture loss and significantly inhibited the fungal growth and spoiling for over 6 days at RT and 12 days at fridge conditions maintaining the visual appearance and natural color of the fruit. The findings in this work indicated the potential of reported CD as non-cytotoxic, UV-blocking antimicrobial additives for the development of edible coatings and packages for their use in the food industry, as well as pharmaceutical and healthcare applications.

A Rare Case of Oral Myiasis Caused by Lucilia sericata in an Intubated Patient from Southeast Turkey

The infestation of human and animal tissues or organs by the larvae of flies is collectively termed as myiasis. The occurrence of oral myiasis is analogously low compared with cutaneous myiasis as oral tissues are not habitually exposed to the external environment. Oral myiasis predominantly affects the periodontium, buccal and/or palatal mucosa, lips, and tongue. The prevalence of myiasis is substantially higher in tropical and subtropical regions, especially in developing countries. This research adduces a case of oral myiasis related to palatal gingiva in a young boy who was intubated due to pneumonia.
