    Abstract Aim: The aim of this study is to compare the treatment efficacy of the bilateral multiple gingival recession areas with a titanium-platelet-rich-fibrin (T-PRF) and subepithelial connective tissue graft (SCTG) combined with a modified coronal advanced flap (MCAF) and the clinical results.
    Method: In the study, 118 maxillary bilateral multiple Miller I recessions were treated. Gingival index, plaque index, probing pocket depth, gingival thickness, recession height, recession width, keratinized gingival width and open root surface area were measured at baseline and at 6 months. Postoperative pain levels Visual Analog Scale, healing status, wound healing index evaluated with. The results of both groups pre and postoperative were compared.
    Results: The initial recession height was 2.15 ± 1.0 mm in the T-PRF group; 2.04 ± 0.80 mm in the SCTG group. After 6 months, the mean root closure rate was 61.77%, 75.31% in T-PRF and SCTG group, respectively. Clinical attachment gain was achieved in both groups compared to baseline. When the results were compared, the gains achieved in the SCTG group were statistically significantly higher. İt was determined that patient satisfaction was higher in T-PRF group and wound healing was faster.
    Conclusion: Considering the advantages of T-PRF such as providing effective results in the treatment of defects, patient satisfaction and rapid recovery; It can be applied as an alternative to SCTG.
    Clinical significance: T-PRF can be an alternative to SCTG in the treatment of gingival recessions.

    Abstract Farm-scale models quantify the cycling of nitrogen (N) and carbon (C) so are powerful tools for assessing the impact of management-related decisions on greenhouse gas (GHG) emissions, especially on dairy cattle farms, where the internal cycling is particularly important. Farm models range in focus (economic, environmental) and the detail with which they represent C and N cycling. We compared four models from this range in terms of on-farm production and emissions of GHGs, using standardized scenarios. The models compared were SFarMod, DairyWise, FarmAC and HolosNor. The scenarios compared were based on two soil types (sandy clay versus heavy clay), two roughage systems (grass only versus grass and maize), and two climate types (Eindhoven versus Santander). Standard farm characteristics were; area (50 ha), milk yield (7000 kg/head/year), fertiliser (275 kg N and 150 kg N/ha/year for grass and maize, respectively). Potential yields for grass 10t dry matter (DM)/ha/year in both areas, maize 14 t DM/ha/ year in Eindhoven and 18t DM/ha/ year in Santander. The import of animal feed and the export/import manure and forages was minimized. Similar total farm direct GHG emissions for all models disguised a variation between models in the contribution of the different on-farm sources. There were large differences between models in the predictions of indirect GHG emission from nitrate leaching. Results could be explained by differences between models in the assumptions made and detail with which underlying processes were represented. We conclude that the choice of an appropriate farm model is highly dependent upon the role it should play and the context within which it will operate, so the current diversity of farm models will continue into the future.

    Abstract An ecosystem diversity index was proposed by the present study. The proposed index (H_wd ) considers not only the species compositions of the meta communities and their land cover areas but also heterogeneities of their geographical distributions. H_wd is therefore includes fractal dimension (w_j ) as well as Shannon-like expression of average conflict (H_d ). Estimation of ecosystem evenness was also given in the present study. With regard to ecosystem evenness (E_wd ), the proposed equation is H_wd⁄(2 ln⁡K ) since maximum fractal dimension value of a meta community equals to 2 (w_maxj=2). The purpose of the ecosystem diversity and evenness indices give the information as numerical data about the general conditions of the ecosystems. Both of the indices may therefore be employed for monitoring and comparing the ecosystems.

    Abstract This study examines the synthesis and evaluation of 11 newly developed compounds as potential anti-Alzheimer's agents that occur via cholinesterase and β-secretase inhibition. The compounds were tested for their inhibitory activity against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) using the modified Ellman method. The results showed that several compounds exhibited significant inhibition of AChE, particularly compounds 6d, 7a, and 7e, which demonstrated high inhibitory activity at lower concentrations, with IC

    Abstract Objective: To evaluate the value of multimodal ultrasonography (US) in a rat experimental torsion model after 6 h of torsion with different degrees.
    Methods: Twenty-one male rats were divided into three groups. Left testes of the rats were twisted around their vascular pedicle 360 degrees in group 1, 720 degrees in group 2, and 1080 degrees in group 3 and intact right testes of the rats were accepted as control group. Grey-scale US, superb microvascular imaging (SMI), colour Doppler ultrasonography (CDUS), strain elastography (SE), and two-dimensional (2-D) shear wave elastography (SWE) examinations were applied 6 h after torsion procedure and testes were removed for pathological evaluation.
    Results: Short-axis dimensions and volumes of the torsion side were higher than control testes. Lengths of the testes in the 3rd torsion group were smaller than the testes in groups 1 and 2 (P < 0.002). SMI was better than CDUS in recognizing blood flow in testicular tissue. Strain ratios were higher in group 1 and decreased with the increasing torsion degree. Emean and standard deviation (SD) measurements increased in the torsion side. Pathologically the mean testicular damage scores were statistically significant between torsion and control testes in all groups.
    Conclusion: Our results showed that short-axis and volume measurements, SMI, 2D-SWE, and SE are effective in the evaluation and diagnosis of testicular torsion (TT).
    Advances in knowledge: Evaluation of affected testis and intact testis with multiparametric US in late presenting TT cases is more reliable than being dependent on a single sonographic modality.

    Abstract Witnessing interparental conflict in childhood predicts psychological dating violence victimization (PDVV) in adulthood. As found in previous studies, PDVV and hopelessness are associated with depression. However, the associations among these four variables have not been explored in detail. The present study, therefore, examined the association between perceived interparental conflict and depression in adulthood and whether PDVV and hopelessness might operate as sequential mechanisms accounting for the association.

    Abstract In this study, the prevalence of ESBL/pAmpC-producing Escherichia coli and their molecular characterization from cloacal swab samples were investigated. All samples were obtained from broiler flocks that are located in Hatay, Adana, and Mersin provinces of Turkey. Antimicrobial susceptibilities of the isolates were determined by disk diffusion method following the CLSI criteria. Genetic mechanisms mediating resistance in ESBL/pAmpC-producing E. coli isolates were identified by polymerase chain reaction (PCR) and followed by DNA sequencing. Phylogenetic groups and plasmid replicon types of the isolates were also investigated by PCR. The clonal relationship of selected isolates was investigated by enterobacterial repetitive intergenic consensus (ERIC)-PCR and multilocus sequence typing (MLST) method. Of 430 cloacal swab samples, 154 (35.8%) were positive for ESBL/pAmpC-producing E. coli. The ESBL/pAmpC type beta-lactamases were as follows: CMY-2 (n = 46), CMY-2 + TEM-1b (n = 63), SHV-12 (n = 5), SHV-12 + TEM-1b (n = 12), CTX-M-3 (n = 14), CTX-M-3 + TEM-1b (n = 1), CTX-M-15 (n = 4), CTX-M-15 + TEM-1b (n = 4), and CTX-M-1 (n = 3). Moreover, various rates of resistance to different antimicrobials were determined such as nalidixic acid (92.9%), ciprofloxacin (76%), sulfamethoxazole-trimethoprim (78.6%), tetracycline (73.4%), streptomycin (52.6%), chloramphenicol (44.2%), kanamycin (27.9%), tobramycin (24.7%), gentamicin (19.5%), and amikacin (0.6%). Furthermore, 148 (96.1%) isolates were found to be MDR. The ESBL/pAmpC-producing isolates were distributed into the following phylogroups: E (n = 61), B1 (n = 30), F (n = 20), A (n = 19), B2 (n = 11), D (n = 10), and C (n = 3). ERIC-PCR analysis showed 51 unrelated patterns. Out of the 28 selected isolates, the following sequence types (STs) were detected: ST354 (n = 3), ST114 (n = 3), ST5696 (n = 2), ST156 (n = 2), ST174 (n = 2), ST362 (n = 2), ST157 (n = 2), ST5114 (n = 2), ST6635, ST539, ST457, ST1640, ST95, ST5843, ST1158, ST10, ST648, and ST4248. The results of the current study revealed that broilers in Turkey are important reservoir of ESBL/pAmpC-producing E. coli, which suggest that these agents have a great potential of transmission to humans by food chain or direct contact.

    Abstract Sugar beet (Beta vulgaris ssp. vulgaris) is primarily used in sugar production worldwide. Expansins are a gene family of cell wall proteins effective in regulating cell wall structure. They also participate in developmental stages, including cell and leaf growth, root development, and fruit ripening. This study comprehensively characterizes the expansin gene family members found in the sugar beet genome. In addition, in silico expression analysis of sugar beet expansin genes under variable abiotic stress conditions and expression profiles of expansin genes under combined drought and heat stresses by the qRT-PCR method were evaluated in the study. A total of 31 sugar beet expansin genes were identified. BvuEXLA-02 and BvuEXLB-02 genes can have abiotic stress tolerance roles besides their roles in normal development. Determining the properties of sugar beet expansin, family members can help enable the cellulose hydrolysis mechanism and raise plant biomass. Elucidating expression profiles of the sugar beet expansin genes under variable stress conditions can support improving plant productivity. The results of the current study may also contribute to the deep understanding of sugar beet expansin genes in the future.
