This cross-sectional study explores the potential relationship between reticulated platelets (RPs) and CSF in stable coronary artery disease patients.

Patellar instability is an important cause of knee disability in children and adolescents. A recent population-based study found an annual incidence rate of 2.58 per 100 000 individuals for lateral patella dislocations (LPD), with higher rates in females and patients aged

Rapid degradation in body fluids is known to be the main shortcoming of the AZ31 magnesium alloy that is aimed to be controlled in this study by chemical conversion of its surface in various phosphate and chloride solutions. Deposited layers on the surface of bare alloy plates were subjected to compositional and morphological analyses to assess their performance as barriers to degradation. Also changes in the mass of the samples and pH of the solutions were monitored during 21 day immersion periods. Formations of prismatic, platelike, needlelike crystals of various compositions including calcium phosphates, magnesium phosphates, magnesium chlorides were observed by scanning electron microscopy and their atomic compositions were determined by EDX and quantitative XRD analyses. The results indicate that a layer of ceramic of various thicknesses can stably form on the base alloy by simple adsorption of the particles suspended in the solution or by nucleation and growth of the products of reactions between dissolved ions and the metal ions released from the surface. These deposition layers that are solely induced by the electrochemical potential of the species in the solution offer facile surface modification methods and novel phases to control the degradation of magnesium alloys in aggressive environments such as body fluids or marine environments.

Category: Other Introduction/Purpose: The significance of trial registration has grown rapidly as an increasing number of journals require NCT IDs prior to publication. Although various reports have been published in different medical fields, including several orthopaedic subspecialties, no study has examined the discrepancies between trial registries and publications in the area of foot and ankle surgery. Therefore, this study aimed to investigate (1) the characteristics of foot and ankle surgery-related clinical trials registered in the widely used Clinicaltrials.gov (CTG) clinical trials database, (2) the publication rates, (3) inconsistencies between the original trial plans and final publications, and (4) possible risk factors that could contribute to discrepancies. The hypothesis was that foot and ankle surgery-related trials would have a low publication rate, and discrepancies would exist between trial registries and final published results. Methods: The study used the CTG database to identify eligible trials based on the following inclusion criteria: (1) related to foot and ankle surgery, (2) interventional study, (3) randomized controlled, and (4) anticipated completion date before the end of 2018. Exclusion criteria consisted of (1) ongoing trials, (2) trials assessing vascular surgeries or anesthetic procedures, and (3) trials examining conservative treatment methods without any surgical intervention. The search was performed on January 1, 2021, allowing the authors at least 24 months from trial completion to publication. The corresponding publications of the included trials were searched using various databases, including Medline, Web of Science, Scopus, and Google Scholar. NCT ID, title, keywords, and the name of the principal investigator provided in CTG were used for literature search, and the title and abstract of the publications were reviewed to confirm the match with the trial. Results: Out of all the trials analyzed, 67.5% were registered either during the trial period or after completion. Industry funded 46.5% of trials. A reported 54.8% of trials were completed, and only 42% (66 trials) were published in a journal. Among the analyzed trials, 57.6% had a sample size discrepancy, 28.8% had a follow-up time discrepancy, 45.5% had a primary outcome discrepancy, and 89.4% had an inclusion/exclusion criteria discrepancy. Trials funded by industry exhibited significantly more sample size and inclusion/exclusion criteria discrepancies (p=0.024, 0.001, 0.037, respectively). Furthermore, industry-funded studies had a higher frequency of positive results (p=0.011). Conclusion: The findings of this study draw attention to the existing issues in clinical trials related to foot and ankle surgery. The results not only serve as a warning to researchers regarding potential inconsistencies but also support the need for stricter trial registry regulations. Registering a trial does not guarantee its publication or ensure that there will be no modifications to the methodology during the trial period. Therefore, it is crucial to register trials before enrolling the first patient to minimize the risk of bias.

Category: Ankle; Trauma Introduction/Purpose: The proposed ideal alignment for the syndesmosis involves a line connecting the centroids of the fibula and tibia, but there is uncertainty about the optimal intraoperative method for determining the appropriate fixation angle. This is due to the fact that the AO guidelines do not account for patient or level-specific factors, and the determination of the angle relative to the coronal plane relies on the surgeon's judgment. Inexperienced trauma surgeons may encounter significant problems with syndesmotic malalignment as a result. The goal of this study was to validate the effectiveness of the angle bisector method using computed tomography and 3D-printed ankle models, in order to determine whether it can assist in achieving proper screw trajectory for syndesmotic fixation. Methods: The angle bisector method was utilized to identify a precise trajectory for the true syndesmotic axis, using the bisector of the angle formed by two lines tangential to the anterior and posterior fibula and tibia. CT validation was made on CT angiography of 50 consecutive patients. DICOM data from 16 ankles were used to create 3D anatomical models which were printed using a desktop FDM printer. Two trauma surgeons performed syndesmotic fixations using the angle bisector method at 2 cm and 3.5 cm proximal to the joint space, after identifying the bisector of the angle formed by two K-wires tangential to the anterior and posterior fibula and tibia. The axial sections of CTs and printed 3D-models were analyzed using software to determine the relationship between centroidal axis and the inserted screws. The measurements were made twice by two blinded observers, with a two-week interval. Results: The results of the study show that the angle bisector method provides a reliable direction with minimal differences at both the 2 cm and 3.5 cm levels. The average angle between the centroidal axis and screw trajectory was 2.4° ± 2° at the 2 cm level and 1.3° ± 1.5° at the 3.5 cm level. Furthermore, the average distance between the fibular entry points of the centroidal axis and screw trajectory was less than 1 mm at both levels, indicating that the angle bisector method can serve as an excellent entry point for syndesmotic fixation on the fibula. The inter- and intra-surgeon analyses showed excellent consistency, with all ICC values above 0.90. Similarly, inter- and intra-observer consistencies regarding the measurements were also excellent. Conclusion: The study demonstrated that the angle bisector method was successful in identifying the original syndesmotic axis and aided in the precise placement of implants in the desired direction. The method has the potential to be replicated intraoperatively and could serve as a basis for the development of a novel surgical guide for determining the correct syndesmotic axis. However, safety analysis using cadavers should be conducted prior to clinical implementation.

Objective:The purpose of this study is to assess and compare outcomes of two different timing surgery for moderately carpal tunnel syndrome (CTS).Methods:Eighty-eight patients who underwent early and late due to CTS were evaluated retrospectively. Patients with early surgery and late surgery were divided into two groups. Preoperative and postoperative visual analog scale (VAS) score and postoperative Boston Carpal Tunnel Questionnaire (BCTQ) scores of both groups were compared.Results:Preoperative and postoperative VAS scores were compared, there was a significant decrease in both groups. When BCTQ results of both groups were compared, the results of patients who underwent early surgery were statistically better.Conclusion:In conclusion, we think that early surgery is better clinically in patients with moderately CTS.

Purpose: The aim of the present study was to evaluate survivin immunoexpression and the clinicopathologic correlations in serous borderline ovarian tumors (BOT) patients ≤ 40 years old. Materials and Methods: A total of 36 BOT cases were evaluated. After excluding the mucinous type and patients over 40 years of age, 20 serous BOT cases meeting the criteria were included. A similar number of benign ovarian cysts and 20 serous malign ovarian tumors were randomly included as the control group. The patients were then staged based on their surgical findings and 2014 FIGO criteria, and their histological tumor types obtained from pathological specimens were determined using WHO criteria. The survivin levels in the specimens were analyzed using immunohistochemical assays. Results: Positive survivin expression was detected in 10% of benign tumors, 100% of serous BOTs, and 100% of serous malign ovarian tumors. Mean survivin immunoreactivity was statistically similar between groups and it was found to be significantly higher in both groups compared to the control group. Survivin expression was positively correlated with FIGO stage, tumor grade, microinvasion, and micropapillary pattern. Conclusion: Survivin immunoexpression is correlated with the malignancy potential of serous BOTs, and that survivin immune expression may be a histopathological marker that will help in making a decision on fertility-sparing surgery and follow upin young patients.

TiB2 (titanium diboride) is a transition metal boride with remarkable properties and, its thinfilm coatings can be deposited on various substrates to develop the wear resistance properties of substrates. Radiation interaction properties of TiB2 coated glass and HSS are very significant as well for shielding applications and it has not been investigated so far. In this work, linear attenuation coefficient (µ), half-value layer (HVL), tenth-value layer (TVL) and mean free path (MFP) of TiB2 coated glass and HSS (AISI-M2) were measured using a 133Ba radioactive point source at energies 80.8, 276.4, 302.8, 356 and 383.8 keV. A comparison has been made with some radiation shielding concretes with respect to MFP. Energy absorption and exposure buildup factors (EABF and EBF) of composites were also calculated in the experimental energy region 50 – 500 keV. TiB2 coated glass and HSS were found to be better radiation shielding materials than the standard shielding concretes concluding that they can be further developed for radiation shielding applications.

We report a 44-years-old woman with cystic echinococcosis (CE) who presented with simultaneous involvement of liver and vastus lateralis muscle to Istanbul University-Cerrahpasa, Istanbul, Turkey in 2020. Although she underwent surgery for the liver, the intramuscular mass was ignored. While the patient was under post-operative albendazole treatment, she was investigated for the mass on her right thigh which was excised later. The comparison of magnetic resonance imaging before and after albendazole treatment showed that albendazole eliminated the intramuscular vesicle structures by accelerating the degeneration process of the cyst. The comparison of pathology samples sent from both liver and intramuscular CE also revealed that the albendazole has left the laminar membrane intact, degenerate the germinative membrane, thereby reducing the intra-vesicle pressure and also caused the scolex structures to disappear. To the best of our knowledge, this is the first paper to report the effect of preoperative albendazole treatment on the structure of intramuscular CE.

Direct Writing (DW), also known as Robocasting, is an extrusion-based layer-by-layer manufacturing technique suitable for manufacturing complex geometries. Different types of materials such as metals, composites, ceramics, biomaterials, and shape memory alloys can be used for DW. The simplicity and cost-efficiency of DW makes it convenient for different applications, from biomedical to optics. Recent studies on DW show a tendency towards the development of new materials and applications. This represents the necessity of a deep understanding of the principles and parameters of each technique, material, and process challenge. This review highlights the principles of many DW techniques, the recent advancements in material development, applications, process parameters, and challenges in each DW process. Since the quality of the printed parts by DW highly depend on the material extrusion, the focus of this review is mainly on the ceramic extrusion process and its challenges from rheological and material development point of view. This review delivers an insight into DW processes and the challenges to overcome for development of new materials and applications. The main objective of the review is to deliver necessary information for non-specialist and interdisciplinary researchers.

The incidence of papillary microcarcinoma (PMC) keeps raising due to fine needle aspiration (FNA) biopsies and the pathologic evaluation of thyroid specimens of cases operated for benign thyroid disorders. The files of 78 patients who underwent surgery between January 2006 and May 2013 in our department and were diagnosed with PMC were analyzed, retrospectively.Cases were grouped as incidental and non-incidental depending on the preoperative diagnosis. The diameter of the nodules in the preoperativeultrasonographic examination, pathological parameters such as tumor size, bilaterality, multifocality,and capsular invasion were found significantly high in non-incidental group(P

Objective The present study aimed to evaluate an anatomical region, the anterior uterocervical angle (UCA), to determine whether it plays a role in unexplained infertility. Methods In this prospective, cross-sectional study, unexplained infertile and healthy fertile (controls) women were compared. The longitudinal and transverse axes of the uterine cervix and uterine corpus were measured by transvaginal ultrasonography. The UCA was determined as the angle between two lines. One line was drawn between the internal and the external os, and the other was drawn through the internal cervical os and was parallel to the lower side of the front part of the uterine wall in the internal os. Demographic characteristics and uterocervical ultrasonographic measurements were compared between the two groups. Results Eighty participants, aged from 20 to 35 years, were enrolled (unexplained infertile [n = 30] and healthy fertile women [n = 50)]. The mean lengths of the uterine corpus longitudinal axis, uterine corpus transverse axis, and uterine cervix longitudinal axis were similar between the groups. The mean UCA was significantly higher in healthy fertile women (131.9 ± 22.9 degrees) than in women with unexplained infertility (114.2 ± 17.3 degrees). Conclusion The present study shows that a narrow anterior UCA is associated with unexplained infertility.

Objectıve: Both pelvic masses and preoperative diagnosis of them have still continued as an important investigation subject. It is important to discriminate the diagnoses of leiomyoma and adenomyosis before operation especially among infertile patients. Neoplasm can alter systemic or local immune response in their originating area. We aim to investigate using new inflammation markers, neutrophil to lymphocyte ratio and platelet to lymphocyte ratio, whether they are useful to discriminate between adenomyosis and leiomyoma. Study Design: We reviewed a database of all patients that had complaint from abnormal uterine bleeding resistant to medical treatment or detected pelvic mass in perimenopausal period and underwent hysterectomy in our department between January 2011 and July 2016 for study groups. However, a total of 124 patients (44 adenomyosis and 80 leiomyoma) were evaluated because of exclusion criteria and matched with 72 women who were healthy and had normal uterus and ovaries as a control group. Results: Neutrophil and platelet count, neutrophil to lymphocyte ratio and platelet to lymphocyte ratio levels were significantly higher in adenomyosis group than in control group (p=0.039, p=0.046, p=0.001 and p=0.046 respectively). Neutrophil count and neutrophil to lymphocyte ratio levels were significantly higher in adenomyosis group than in leiomyoma group (p=0.039 and p=0.001, respectively). Conclusıon: As a result, high neutrophil count and neutrophil to lymphocyte ratio levels may be useful marker to discriminate between adenomyosis and leiomyoma. Therefore, the examinations, which are more invasive and more expensive such as magnetic resonance imaging, may be less need by the agency of combined use of those inflammation markers and ultrasound in preoperative period.

Objective: To reveal whether adolescent mothers are at higher risk of poor fetal and maternal outcomes compared with non-adolescent mothers. Study Design: 426 nulliparous women having a single pregnancy and gave birth with a birth-weight >500g or >24 weeks’ gestation were included. Participants were divided into three groups. 1. Group consisted of adolescents between ages of 16-17(n=56), 2. Group 18-19 ages(n=185) and 3. Group 20-24 ages(n=185). Adverse maternal and fetal outcomes compared among groups. Results: The mean maternal age was 16.6(±0.40), 18.1(±0.55), 22.6(±0.60) in groups, respectively. Antenatal visits number, smoking status, vaginal delivery, emergency cesarean delivery rates (fetal distress or cephalopelvic disproportion), perineal infection, postpartum hemorrhage, transfusion requirement, maternal death were not statistically significant among groups (p=0.871, p=0.935, p=0.450, p=0.961, p=0.737, p=0.112, p=0.996, p=0.859 and p=1, respectively).

In this work, manganese (II, III) oxide, (Mn3O4) doped zinc soda lime silica glasses have been synthesized using a conventional melt-quenching process and followed by control heat treatment process. The crystal phase composition and optical properties of α-Zn2SiO4:Mn3O4 based glass-ceramics are comprehensively studied. The physical properties and crystal growth of α-Zn2SiO4 phase were measured by density analysis, linear shrinkage, X-ray diffraction (XRD) and Fourier transform infrared reflection (FTIR) spectroscopy. From the measurement, the average density and linear shrinkage of α-Zn2SiO4:Mn3O4 based glass-ceramics increased with increasing heat treatment temperature. Besides, the presence of Zn–O–Si bands indicates the formation of α-Zn2SiO4 crystal phase and causing the decrement of energy band gap. The photoluminescence spectra of Mn2+ ions exhibit emission transitions of 4T1(G)–6A1(S) and show a prominent green emission colors of α-Zn2SiO4 phase at 524 nm.

In the present work, seven glass samples have been prepared utilizing melt-quenching method with composition of 40B2O3-10SiO2-10Al2O3-30ZnO-10 (Li2O/Na2O/K2O/MgO/CaO/SrO/BaO) all in mol%. Scanning electron microscope (SEM) and Energy-dispersive X-ray spectroscopy (EDX) have characterized for H3 (K2O) and H7 (BaO), to examine the structural properties. X-ray Photoelectron Spectroscopy (XPS) has shown that the boron (B) element composition is highest after oxygen elements in all the glasses. It has been also observed that incorporation of potassium (K) and strontium (Sr) elements are maximum compared to the other doped elements into the glass. Further, the photon shielding for H1-H7 samples were also studied. We calculated the mass attenuation coefficients (μ/ρ) for the present samples at some energies between 0.015 and 10 MeV. The results revealed that H7 (BaO) sample owns the highest μ/ρ values followed by H6 (SrO) while H1 (Li2O) has the lowest μ/ρ. Moreover, H7 and H6 samples have higher effective atomic number than the rest of glasses. H7 sample has excellent shielding properties when compared with the other glasses. We found that the composition of the sample affects the attenuation of the glasses and high attenuation can be achieved when we used heavy metal oxides (such as BaO).

Background. Primary dysmenorrhea, defined as painful menstrual cramps originating in the uterus without underlying pathology, is a gynecological disease that affects quality of life and school success. Our goal was to determine the effect of anterior uterocervical angle on primary dysmenorrhea and disease severity. Methods. A total of 200 virgin adolescents, 16 to 20 years of age, were included in the study. The Andersch and Milsom scale was used to determine dysmenorrhea severity. Those with pathologies causing secondary dysmenorrhea were excluded from the study. Study subjects were grouped based on severity of pain. Demographic characteristics and uterocervical ultrasonographic measurements were compared among groups. Results. Of the 200 participants enrolled in the study, 50 were healthy controls and 150 had primary dysmenorrhea. Those with primary dysmenorrhea had a significant family history of primary dysmenorrhea compared with controls (P

Efficient parallel screening of combinatorial libraries is one of the most challenging aspects of the high-throughput (HT) heterogeneous catalysis workflow. Today, a number of methods have been used in HT catalyst studies, including various optical, mass-spectrometry, and gas-chromatography techniques. Of these, rapid-scanning Fourier-transform infrared (FTIR) imaging is one of the fastest and most versatile screening techniques. Here, the new design of the 16-channel HT reactor is presented and test results for its accuracy and reproducibility are shown. The performance of the system was evaluated through the oxidation of CO over commercial Pd/Al2O3 and cobalt oxide nanoparticles synthesized with different reducer-reductant molar ratios, surfactant types, metal and surfactant concentrations, synthesis temperatures, and ramp rates.

Objective: Carcinosarcomas of the breast are rare and aggressive breast tumors. The optimal treatment strategies and the classification of these difficult to diagnose tumors are not clear in the literature due to their very low incidence. In this study, we aimed to evaluate patients who were operated on for breast carcinosarcoma and discuss the current literature.Materials and Methods: Ten patients who were treated with a diagnosis of breast carcinosarcoma between January 2000-March 2013 at the Izmir Bozyaka Teaching and Training Hospital General Surgery Clinics were retrospectively analyzed.Results: The mean age of the patients was 59.7 (±13.4) years. Eight patients underwent modified radical mastectomy, one patient lumpectomy and one patient breast conserving surgery + sentinel lymph node biopsy procedures. The TNM stage of patients were identified as stage 1 in 2 patients, stage 2 in 6 patients, and stage 3 in 2 patients. 60-month disease-free survival rate was 52.5% (±18.6). The overall survival rate was 53.3% (±20.5). Four patients died during follow-up.Conclusion:It is reported that the prognosis of carcinosarcomas are as poor as triple negative epithelial tumors. In contrast to the literature, in our study the disease-free and overall survival rates according to stage were not different from epithelial tumors. In this regard, prospective studies including more patients are required.

The study aimed to examine the in vivo inhibition effect of cobalt ion and silibinin on metabolic enzymes such as glucose-6-phosphate dehydrogenase (G6PD), 6-phosphogluconate dehydrogenase (6PGD), glutathione reductase (GR), and glutathione S-transferase (GST) and their in vitro inhibition effect on 6PGD. Twenty-four Wistar Albino rats weighing approximately 250-300 g were used in the study. The rats were divided into 4 groups as group 1 (control): isotonic serum (0.5 mL i.p), group 2 (cobalt): (150 mg kg/day cobalt), group 3 (silibinin): (100 mg/kg/day silibinin), group 4 (cobalt + silibinin). As a result of the in vivo applications, a statistically significant decrease was observed in the activities of G6PD ( p < 0.05), 6PGD ( p < 0.05), GR ( p < 0.05), and GST ( p < 0.05) enzymes in the groups that were administered cobalt compared to the control group. It was also found that the activities of G6PD ( p < 0.05), 6PGD ( p > 0.05), GR ( p > 0.05), and GST ( p > 0.05) enzymes increased in groups that were administered cobalt + silibinin compared to the group that was administered cobalt. As for in vitro applications, it was found that different Co 2+ ions inhibited 6PGD enzyme which was obtained as a result of purification with IC 50 = 346.6 μM value, while silibinin increased 6PGD enzyme activity within the concentration range of 100-750 μM by 40%. As a result, it was found that cobalt ions had an inhibition effect on G6PD, GR, and GST enzymes, which are vitally important for living metabolism, in vitro and in vivo and inhibited 6PGD enzyme activity in vitro, and silibinin increased these enzyme activities in vivo and 6PGD enzyme activity both in vivo and in vitro and decreased the inhibition effect., Competing Interests: The authors declare no competing financial interest., (© 2023 The Authors.

This study aimed to investigate the protective effects of arbutin (ARB) against brain injury induced in rats with potassium bromate (KBrO 3 ). The rats were divided into four groups as Group 1: Control (0.9% NaCl ml/kg/day p.), Group 2: KBrO 3 (100 mg/kg (gavage), Group 3: ARB (50 mg/kg/day p.), and Group 4: KBrO 3  + ARB (100 mg/kg (gavage) + 50 mg/kg/day p.). At the end of the fifth day of the study, the rats in all groups were killed, and their brain tissues were collected. In the collected brain tissues, malondialdehyde (MDA), superoxide dismutase (SOD), and catalase (CAT) levels were measured, and routine histopathological examinations were made. The MDA levels in the group that was exposed to KBrO 3 were significantly higher than those in the control group (p ˂ 0.001). In comparison to the KBrO 3 group, the MDA levels in the KBrO 3  + ARB group were significantly lower (p ˂ 0.001). It was observed that SOD and CAT enzyme activity levels were significantly lower in the KBrO 3 group compared to the control group (p ˂ 0.001), while these levels were significantly higher in the KBrO 3  + ARB group than in the KBrO 3 group (p ˂ 0.001). Additionally, the group that was subjected to KBrO 3 toxicity, as well as ARB administration, had much lower levels of histopathologic signs than the group that was subjected to KBrO 3 toxicity only. Consequently, it was found that KBrO 3 exposure led to injury in the brain tissues of the rats, and using ARB was effective in preventing this injury., (© 2022 Wiley Periodicals LLC.)

In recent years rapidly growing antibiotic resistance has increased interest toward natural products, especially essential oils because of their various effects. The aim of this study was to identify the chemical composition of the commercial Origanum onites essential oil (EO) and to investigate the antimicrobial activity by disc diffusion and dilution methods, against ten different ATCC strains, including eight bacteria, two yeasts and seventy-nine clinical nosocomial Escherichia coli isolates that produce extended spectrum beta lactamase (ESBL). The chemical composition of EO was analyzed by GC and GC-MS. The major compounds of the EO were determined as carvacrol (51.4%) followed by linalool (11.2%), p-cymene (8.9%) and γ-terpinene (6.7%). O. onites EO had antimicrobial activity against all standard strains and inhibited microbial growth of ESBL positive E. coli isolates. According to our results, O. onites EO may be an alternative to synthetic drug, used in combination with other antibiotics for treatment of infection caused by multidrug resistant bacteria after testing toxic effects and irritation at preferred doses on human.

The hydroalcoholic extracts of the Turkish traditional coffee samples from 18 commercial brands were tested for their neurobiological effects through enzyme inhibition based on enzyme-linked immunosorbance microtiter assays against acetylcholinesterase, butyrylcholinesterase, and tyrosinase, linked to Alzheimer's and Parkinson's diseases. The extracts were also subjected to several antioxidant test systems to define their antiradical, metal-chelation capacity, and reducing power. Total phenol and flavonoid contents in the extracts were delineated by spectrophotometric methods, while chlorogenic acid in the coffee samples was quantified by high-pressure liquid chromatography. The extracts displayed low to moderate inhibition (from 2.13 ± 0.01% to 36.12 ± 1.07% at 200 μg/mL) against the tested enzymes, whereas they had notable 2,2'-diphenyl-1-picrylhydrazyl radical scavenging activity up to 56.15 ± 2.03% at 200 μg/mL. The extracts exerted a remarkable ferric-reducing antioxidant power values, while chlorogenic acid was found to range between 0.288 ± 0.005% and 2.335 ± 0.010%., (Copyright © 2015.

Medicinal and edible plants play a crucial role in the prevention and/or mitigation of different human diseases from ancient times to today. In folk medicine, there are different plants used for infectious disease treatment. During the past two decades, much attention has been paid to plants as novel alternative therapeutic agents for the treatment of infectious diseases due to their bioactive natural compounds such as phenol, flavonoids, tannins, etc. The genus Eryngium (Apiaceae) contains more than 250 flowering plant species, which are commonly used as edible and medicinal plants in different countries. In fact, some genus Eryngium species are used as spices and are cultivated throughout the world and others species are used for the treatment of hypertension, gastrointestinal problems, asthma, burns, fevers, diarrhea, malaria, etc. Phytochemical analysis has shown that genus Eryngium species are a rich source of flavonoids, tannins, saponins, and triterpenoids. Moreover, eryngial, one the most important and major compounds of genus Eryngium plant essential oil, possesses a significant antibacterial effect. Thus, the objective of this review is to critically review the scientific literature on the phytochemical composition and antibacterial effects of the genus Eryngium plants. In addition, we provide some information about traditional uses, cultivation, as well as phytochemistry.

In this work, two alkaloids namely (+)-buxabenzamidienine (1) and (+)-buxamidine (2) were isolated from Buxus sempervirens, using bioassay-guided fractionation and isolation method. Their acetyl- (AChE) and butyrylcholinesterase (BChE) inhibitory activities were studied and the compounds were found to be quite selective inhibitors of AChE. IC50 values of compound 1 for electric eel AChE and horse BChE were 0.787 and 7.68 mM, respectively; while the corresponding IC50 of compound 2 were 1.70 and 549.98 mM, respectively. Theoretical (quantum mechanical, homology modelling and docking) calculations were performed in order to explain their interactions with different AChE (electric eel and human) and BChE (horse and human). The x-ray crystal structures of electric eel AChE, human AChE, human BChE and a model of horse BChE constructed by homology with human BChE were used for docking of compounds 1 and 2. Density functional theory (DFT) calculations of the compounds were performed at the B3LYP/6- 31G** level using the program Spartan™, and their HOMO and LUMO energy levels were calculated. Docking studies exhibited that compound 1 interacts with the acyl-binding pocket of the active site gorge of huAChE, and including several other hydrophobic interactions.

In European folk medicine, Salvia species have traditionally been used to enhance memory. In our previous study of 55 Salvia taxa, we explored significant anticholinesterase activity of cultivated S. fruticosa. In this study, we compared the inhibitory activity of dichloromethane, ethyl acetate, and ethanol extracts of 3 wild-grown samples and 1 cultivated sample of S. fruticosa against acetylcholinesterase and butyrylcholinesterase enzymes (which are associated with pathogenesis of Alzheimer's disease) by using the spectrophotometric Ellman method. Antioxidant activities were assessed by determining 2,2-diphenyl-1-picrylhydrazyl radical-scavenging activity, iron-chelating capacity, and ferric-reducing antioxidant power. The dichloromethane extract of the cultivated sample was then subjected to fractionation by using open column chromatography and medium-pressure liquid chromatography to obtain the most active fraction by activity-guided fractionation. All fractions and subfractions were tested in the same manner, and inactive subfractions were discarded. The essential oil of the cultivated sample was analyzed by gas chromatography-mass spectrometry.

Even a brief conceptual review of the current developments in the health care industry indicates that the future of independent medical practitioners is rather challenging. It may be necessary for these parties to pursue proactive and aggressive marketing strategies to be able to compete with the managed care organizations.
