- Abstract
The aim of this research was the micromorphological and mineralogical characterization of calcrete outcrops located in central Morocco, with particular focus on microstructure development and palygorskite formation processes. Two study sites in the Al Haouz Plain (ca 30. km west to Marrakech city) were identified, in an area dominated by Quaternary sedimentary formations including layers cemented by carbonate and widespread calcareous crusts at the surface. The calcrete samples were examined by means of polarizing microscopy from thin sections, scanning electron microscopy / energy-dispersive X-ray spectroscopy (SEM/EDX) from undisturbed samples, and X-ray diffraction (XRD) methods. The matrix of the calcrete material cementing the schist fragments composed of abundant calcite was associated mainly with palygorskite, quartz, and to a lesser extent illite/mica, feldspar, and chlorite. SEM observations indicated that palygorskite mainly occurred as fibres, fibre bundles and networks mainly grown on and/or enclosing calcite rhombohedrons. The EDX spectra of the palygorskite fibres exhibited strong silicon (Si) peaks followed by Al, Mg and Fe peaks. The EDX analysis of calcite rhombohedric crystals exhibited a strong Ca peak, followed by weak peaks of Si, Mg, Al and Fe possibly due to nearby or overlapped palygorskite crystals. One main palygorskite neoformation process was described. Palygorskite was authigenically formed (neoformed) during and after precipitation of calcite from percolating soil solutions in a near-surface setting. Peculiar sub-rounded microstructural units, here designated as pedogenic ooids/pisoids (according to the size), were determined in the matrix of the studied calcretes, associated to pendants and clay-rich rims surrounding them

Fresh herb ,Weight loss ,Herbal product ,Herbal tea ,Dry herb - Abstract
Objective: Obesity is the most important public health problem of the 21st century. The prevalence of obesity in the community has led people to search for weight loss. In addition to lifestyle changes such as increasing physical activity, eating behavior changes, different body weight protection methods are developed and many of these methods are offered under the name of weight loss products. The aim of this study is to determine the herbal product use approaches for weight loss in women and to determine the factors affecting the use of herbal products. Methods: This descriptive study was conducted on females aged 18-65, living in Denizli province, attending the sports courses twice a week. The research was carried out with 612 participants. The questionnaire was applied to individuals through faceto-face interviews. Results: Approximately half of females use herbal products (41,3%) and a great majority of the participants (70,4%) do not mention their products to their doctors or pharmacists. More than a half of the participants use of herbal products in the forms of tea 62,9%. Most of the participants (54,6%) buy such products from herbalists. It has been detected that 50,6% of the participants use herbal products everyday. Less than a half of them (35,2%) state that they get the necessary information and usage method from their neighbours and relatives. 26,3% of the participants have nausea-vomiting. 79,4% of the females advise the herbal products they use themselves to others. A great majority of them are married (n:439, %71,7) and have graduated from university (n:227, %37,1). Top five dry herbs are cinnamon (12,6%), flax seed (11,5%), oat (11,2%), black sesame (10,6%) and black pepper (8,5%). Lemon (22,9%), parsley (11,5%), tomato (8,3%), mint (7,8%) and avocado (6,9%) are mostly used as fresh herbs. Green tea (20,6%), sage (7,1%), linden (6,9%), cherry stalk (6,1%) and rosemary (5,2%) are preferred as herbal tees. Lemon (39,3%), cabbage (17,0%), onion (12,8%), garlic (11,7%) and tomato (4,2%) are used as herbal juice. Top six popular imported herbal drogs are herbalife (39,0%), green coffee (11,4%), pepper pill (10,4%), apple chromium (9,5%), golden berry (5,7%) and chocolate slim (5,7%). Conclusion: There are still deficiencies in supporting the effectiveness of the use of these products which are sold on various platforms. These products can lead to many side effects which can lead to death. In addition to the necessary regulations on herbal products, toxicological examinations and evidence-based data should be evaluated. © 2020 Refik Saydam National Public Health Agency (RSNPHA).

DRUG side effects ,DRESS syndrome ,OLDER patients ,ANTIPSYCHOTIC agents ,PSYCHIATRIC drugs - Abstract
Introduction: DRESS (Drug Reaction with Eoshinophilia and Systemic Symptoms) syndrome, also called DIHS (Drug-Induced Hypersensitivity Syndrome) is a rare drug-induced systemic hypersensitivity reaction that can be potentially life-threatening (Choudhary et al. J Clin Aesthet Dermatol 2013; 6 -7). Risperidone is an antipsychotic drug with significant antagonist activity at the 5-HT2 and the D2 receptors. It has been reported that risperidone may be effective in controlling agitation, delusion, hallucination, and withdrawal behavior in geriatric patients (Yunusa & El Helou. Front Pharmacol 2020;11:596). Objectives: The aim of this study is to demonstrate the case of developed DRESS syndrome following the use of risperidone. Methods: The 81-year-old female patient was admitted to the Dermatology Clinic due to skin rash, high fever and leukocytosis following the use of risperidone. The patient was consulted to Psychiatry. Results: In her history it was determined that risperidone 0.5 mg/d was started to the patient with depression due to agitative symptom. On the 4th day of treatment, targeoid lesions, starting from the back and spreading first to the trunk and then to the extremities, were observed. Further laboratory examinations revealed that the fever was measured at 39.5 C°, liver enzymes were elevated (ALT= 119 IU/ lt, AST= 124 IU /lt), and significant leukocytosis (WBC =12.000) was present along with the lesions. The patient was planned to be hospitalized to Dermatology Clinic on the 5th day and risperidone was stopped. The patient's agitation increased and following the risperidone discontinuation thereupon the lesions tended to fade and desquamation began. After the treatment of the DRESS syndrome, aripiprazole was given to the patient for agitative symptom. The level of agitation symptoms decreased, and the patient tolerated aripiprazole well without any observed side effects. Image: Conclusions: When initiating medication for the elderly population to address agitation, considering such rare side effects can prevent the patient from being hospitalized due to DRESS syndrome. To the best of our knowledge, this is the first case report associated with DRESS syndrome and risperidone treatment thus, it is necessary to be very careful when starting psychotropic medication for elderly patients.

Introduction: Personality characteristics have an important place in the choices of interns who are at the stage of deciding how their profession will be shaped in the future. While the Big 5 personality model has been widely used in evaluating the personality traits factor in career planning, the Enneagram has increased in popularity in recent years. In this study, it was aimed to investigate how senior medical students evaluate their professional future between these choices and the students' personality types. Objectives: Forms and scales were presented to 221 interns who agreed to participate in our study and were studying in their final year in the 2022-2023 period at three different faculties, two state universities and one private university in the Marmara Region in Turkey. Methods: The sociodemographic data form, Enneagram Personality Types and Subtypes Inventory, and Positive Future Expectation Scale, prepared by the researchers and containing questions about the factors that may be effective in choosing medical specialization, obtained through a face-to-face pilot interview with ten students and literature review, were applied to the participants. Participants answered the forms and scales via 'Google forms'. Results: 211 out of 221 participants, who did not constitute outliers, were included in the analysis. The mean age of the participants was 24.43 (S.E= 0.11) In terms of Enneagram typologies, Type 2 (39.3%) exhibited the highest prevalence, followed by Type 1 (13.3%), Type 6 (11.8%), and Type 7 (8.5%). Furthermore, a statistically significant relationship was found between specialization area and Enneagram types (Fisher exact <.001, p<.001). Post-hoc examinations highlighted specific associations, such as the relationship between Type 3 and Cardiovascular Surgery, Orthopedics and Traumatology; Type 4 and Pneumology, Psychiatry; Type 5 and PRC, Type 6 and Infectious Diseases, Neurology, Medical Microbiology; Type 7 and Cardiology; Type 8 and Pediatrics, Medical Biochemistry; and Type 9 and Family Medicine, Radiology, Psychiatry, Medical Pathology. Conclusions: When the results are evaluated, the highest rate of type 2 and type 1 of the Enneagram typology in senior medical faculty students supports the fact that the medical profession consists of responsible and principled people who love helping others. It is compatible with the character traits of people with type 9 who avoid stress and conflict, preferring the department to have a low workload, and turning to family medicine, radiology, psychiatry and medical pathology departments, which are estimated to have relatively fewer working hours and emergency applications. Our study suggests that this scale be used more widely, as the Enneagram typology, which is used in many professional and career choices, shows results compatible with the participants' preferences in choosing a medical specialty.

- Abstract
Dental implants have become an accepted treatment modality for aging patients with either completely or partially edentulous arches. However, growing patients with congenitally missing primary and/or permanent teeth often need dental implant treatment, even before puberty, for optimum functional and/or psychosocial development. From a developmental perspective, dental implants cannot accompany the physiologic differentiation of the alveolar bone because of the difference in anchorage between an osseointegrated dental implant and a tooth in bone. Nevertheless, reports in the literature suggest that dental implants can be used successfully in partially and completely edentulous arches affected by congenital disorders such as ectodermal dysplasia. In this case report, a multidisciplinary team approach, which included an orthodontist, an oral surgeon, and prosthodontists, in the treatment of a patient with oligodontia is discussed. The orthodontic and prosthodontic treatment sequence, growth analysis from age 14 to 18 years, and successful therapy of an implant associated with late failure is presented. [ABSTRACT FROM AUTHOR]

- Abstract
Anatolia, also called Asia Minor, has an area of about 500,000 km2, is located at the crossroads of Europe, Africa, and Asia (Figure 13.1). Several civilizations namely Hittites, Greeks, Urartians, Persians, Romans, Byzantines, Arabs, Seljuks, Moguls, and Ottomans occupied Anatolia owing to its favorable climate and rich natural resources, including its soils. These various civilizations in turn strongly modified both the cultural and physical landscapes of Anatolia. The story of why they settled in these lands and their effects upon them reflect the special features of its geological and landscape histories. To a very large extent, these are expressed in the soils of Anatolia, which gave them the materials for their nutrition, fuel, clothing, and shelter. In time, the interplay of these products of the soils with the ingenuity of its different inhabitants was to bring Anatolia through the agricultural revolution. Archaeological evidence outlined in this chapter suggests that it may even have provided the location of the very beginnings of the agricultural revolution: Anatolia may have been the crucible of this vital change in mankind’s evolution. This proposition is examined in this chapter, which also describes the state of soils in Anatolia today. © 2014 by Taylor & Francis Group, LLC.

This study, undertaken in the Kapiköy sand dune area of the southern Mediterranean coast in Turkey, detennined the changes in soil quality along with consequent economical revenue following 35 years of acacia, eucalyptus, and stone pine plantations on a 4,900 ha sand dune site. Significant soil phosphate (190 kg/ha) and organic matter (approx. 4%) accumulation were detennined in the zones of vegetation when compared to bare sand dunes within 35 years. Moreover, the local people's incomes from timber and stone pine nut production are increased, denoting a socio-economical improvement in the quality of life. Thus, the project appraised was successful not only for its positive effects on environmental parameters but also on socio-economic aspects. Lessons learned at Kapiköy set significant guidelines for recovering degraded marginal lands in the semi-arid Mediterranean coastal zone of Anatolia. Consequently, the outcomes of this study are expected to increase public awareness of the success of the aforestation projects with evident economic viability.

Pottery ,Traditional knowledge ,Micromorphology ,Neolithic ,Archaeometry - Abstract
Probable source materials and production technologies of neolithic pottery from Çatalhöyük were studied with micromorphological and archaeometrical methods, seeking to shed light on the established techniques and appropriate source material mixtures used by the inhabitants of the epoch (7500 yr BP) in contrast to the reputed idea of primitiveness of the neolithic pottery. The results revealed the use of reed chaff along with mud brick (sun-dried) fragments that may have been derived from brick-making. The application of the 'slip' represents a novel observation and the intention of the use of a dye that needs further confirmation. The presence of gehlenite and aluminum diopside are considered to be the evidence of reached temperatures of about 800°C and not over with short durations manifested by the presence of calcite. Stress phenomena along with the bent weed fragments may also manifest the practice in shaping of pottery, where the former may also reflect fluctuating firing temperatures. Thus, analytical and micromorphological data obtained herein can provide some guidelines on designating prehistoric Anatolian pottery to the archaeologist and potters working on the subject matter. © 2009 Academic Journals.

Mathematical modelling ,Soil moisture - Abstract
For determination of the state of soil water, which is a function of time and depth in soil system, water flux in soil should be modelled. Therefore, designating a suitable model yielding the interactions between soil moisture content (W), water potential (P) and hydraulic conductivity (K) is the pre-requisite. Some samples collected from the some physical and chemical properties. Hydraulic conductivity and soil moisture characteristics of the studied soil were determined by utilizing SIMONA (SIMONA, is basic model describing physical and bio physical processes in agro ecosystem) software most suitable model known at present. For the solution of soil moisture dynamic equation finite differences method was used. The soil water dynamics values obtained from the model and laboratory measurements were also correlated in the studies.

Degradation ,Land use ,Soil erosion ,Deforestation ,GIS ,Geoarchaeology - Abstract
Two well-known ancient sites in southern Anatolia were selected to investigate and quantify the impact of historical land degradation on the Mediterranean coast of Turkey. These sites are the Luwian settlements of Kelenderis (modem Aydincik) and nearby Nagidos (Bozyazi), both in Mersin Province and both occupied since around 4000BP. Changes in local climatic conditions over this period have produced variations in the rates of fluvial transport of sediment/soil from the hinterland into the relevant deltaic regions, thus influencing rates of coastal progradation and aggradation. In addition, both eustatic and neotectonic movements have contributed to deltaic subsidence and/or hinterland uplift, with consequential impact on coastal evolution (positive or negative). The novel geoarchaeological methodology adopted in this study involves the creation of a graphical archive from detailed and standardised measurements taken from rectified mono- and stereoscopic aerial photographs. These archival data were then integrated with data from several types of historical map and field measurements in order to develop a geographical information system (GIS) database that could be interrogated, enabling graphical models of past coastal change to be constructed and calculations then made of the coastal configurations at successive historical periods. These calculations reveal that over the past 6000 years there has been only limited erosion/degradation in the karstic hinterland supplying the sediment to these two study sites (contrary to some previous statements concerning the high degradation risk of Mediterranean karst terrains). Furthermore, rates of progradation in each delta appear to have become diminished or even reversed in the past several decades as a result of both natural and anthropogenic factors. The precise contribution of neotectonic movements in this seismically active zone remains unquantified and is a topic requiring further interdisciplinary study.

- Abstract
Fodder shrub plantations (Atriplex nummularia) were extensively introduced to rehabilitate degraded rangeland and to mitigate desertification in the Rural Municipality of Ouled Dlim (Marrakech Province, Morocco). The original rural landscape, characterised by sparse or absent natural vegetation cover due to a long history of intense grazing activities, has been deeply modified during the last decade by these agroforestry interventions. The purpose of this contribution is to describe the occurred environmental changes under the perspective of the Anthroscape concept, by giving emphasis to the description of the Anthroscape units affected by the plantations and to the geo-pedological processes that influenced the technical success obtained by the interventions. Some critical aspects and possible scenarios of the future evolution of the anthroscapes are also discussed.

- Abstract
This preliminary study reveals that basaltic tephra(pumice) is a material suitable for the production of high quality ceramics and also provides important evidence concerning the transfer of the process of manufacture from the laboratory to commercial production. Specifically, the shapes of pores and the uniformity of the pore size frequency distributions in the basaltic ceramic preparations are the major textural properties controlling compressive strength, whereas the contents and textures of fibrous minerals occupying the pores appear to be less significant in determining the physical properties of these ceramics.

K - Potential ,Eastern Anatolia ,Clay mineralogy - Abstract
Due to its semi-arid climate and sloping topography, Eastern Anatolia has limited soil resources for agriculture, strongly necessitating sustainable land management. Fertile soils occur only in limited areas such as the Gevaş region, where sugar beet is one of the main crops with a particular need for K. Unfortunately, studies on the non-exchangeable (slowly available) and exchangeable K contents, along with soil properties such as clay mineralogy, organic matter content and texture, which are closely related to soil production potential, are not sufficient in the region. Thus, 40 soil samples out of 7 soil series were collected for the determination of the K - potential of the region. Results revealed that the non-exchangeable K (potential) of the Gevaş region soils has predominantly originated from illite and exchangeable K (available) from organic matter and illite. The exchangeable potassium levels for Hasbey II, Yuva, Yemişlik II, Orak and Iskele and Yemişlik, Hasbey, Hasbey III, Güzelkonak, Güzelkonak II are determined to be sufficient for the present non-intensive agriculture, but for the Mülk soils there is a need for K fertilisation. The results of this study are expected to partly relieve the low - income farmers of the area from the economical burden of fertilization for K practiced in the present non - intensive agriculture. © TÜBITAK.

The aim of this research was the micromorphological and mineralogical characterization of calcrete outcrops located in central Morocco, with particular focus on microstructure development and palygorskite formation processes. Two study sites in the Al Haouz Plain (ca 30 km west to Marrakech city) were identified, in an area dominated by Quaternary sedimentary formations including layers cemented by carbonate and widespread calcareous crusts at the surface. The calcrete samples were examined by means of polarizing microscopy from thin sections, scanning electron microscopy / energy-dispersive X-ray spectroscopy (SEM/EDX) from undisturbed samples, and X-ray diffraction (XRD) methods. The matrix of the calcrete material cementing the schist fragments composed of abundant calcite was associated mainly with palygorskite, quartz, and to a lesser extent illite/mica, feldspar, and chlorite. SEM observations indicated that palygorskite mainly occurred as fibres, fibre bundles and networks mainly grown on and/or enclosing calcite rhombohedrons. The EDX spectra of the palygorskite fibres exhibited strong silicon (Si) peaks followed by Al, Mg and Fe peaks. The EDX analysis of calcite rhombohedric crystals exhibited a strong Ca peak, followed by weak peaks of Si, Mg, Al and Fe possibly due to nearby or overlapped palygorskite crystals. One main palygorskite neoformation process was described. Palygorskite was authigenically formed (neoformed) during and after precipitation of calcite from percolating soil solutions in a near-surface setting. Peculiar sub-rounded microstructural units, here designated as pedogenic ooids/pisoids (according to the size), were determined in the matrix of the studied calcretes, associated to pendants and clay-rich rims surrounding them. © 2017 Elsevier B.V.

Geçmişte psikotik bozukluklarda daha yaygın olduğu düşünülen Schneider tarafından tanımlanan belirtiler (STTB) son dönemde yapılan çalışmalarda dissosiyatif bozukluk ve bipolar afektif bozukluk gibi diğer bazı psikiyatrik bozukluklarda da gösterilmiştir. Bunun sonucu olarak da DSM 5’te STTB’e şizofreni tanısındaki özellikli atıf tanı sisteminden kaldırılmıştır. Biz bu çalışmada STTB’i olan iki vakayı sunmayı amaçlıyoruz. Sunulan olgularda STTB’e ilave olarak amnezi ve füg belirtilerinin varlığı ve bu belirtilerin stresli yaşam olayları ile ilişkili olması nedeniyle dissosiyatif bozukluk tanısını da akla getirmekteydi. Bundan dolayı antipsikotik tedavi yerine uygulanan psikoterapötik müdahale ve psikolojik stresörden uzaklaşma yaklaşımlarının STTB açısından da fayda sağladığı gözlemlendi. STTB’in DSM 5’te psikoza özellikli atıfın çıkarılması diğer bozukluklarda da STTB’in klinisyenlerin dikkatini çekmesine neden olacaktır. Böylece bu değişiklik dissosiyatif bozukluk ve bazı bipolar afektif bozukluk olgularının daha iyi tanınmasını sağlayabilir ve hastaların gereksiz yere yüksek doz antipsikotik tedavi almasının önüne geçebilir. Thought to be more common in psychotic disorders in the past, Schneiderian symptoms (SS) were also observed in other disorders such as dissociative disorders and bipolar disorders. As a result of this, specific attribution of Schneiderian first rank symptoms was eliminated from diagnostic criteria of schizophrenia in DSM-5. In this article, we aim to present two cases having schneiderian symptoms. Since these cases had additional symptoms such as amnesia, fugue, and Schneiderian symptoms related to psychosocial stressors, we also suggested that these patients might have dissociative disorders. In terms of Schneiderian symptoms; instead of antipsychotic treatments, psychotherapeutic interventions and removal from psychogenic stressors can be considered in management of these cases. In DSM-5 the elimination of specific attribution of SS in psychosis results in clinician’s drawn attention to this issue in other disorders. Therefore, this alteration may provide better diagnosis of dissociative disorders and bipolar disorders and prevent these patients’ from taking high dose antipsychotic treatments unnecessarily

Fodder shrub plantations (Atriplex nummularia) were extensively introduced to rehabilitate degraded rangeland and to mitigate desertification in the Rural Municipality of Ouled Dlim (Marrakech Province, Morocco). The original rural landscape, characterised by sparse or absent natural vegetation cover due to a long history of intense grazing activities, has been deeply modified during the last decade by these agroforestry interventions. The purpose of this contribution is to describe the occurred environmental changes under the perspective of the Anthroscape concept, by giving emphasis to the description of the Anthroscape units affected by the plantations and to the geo-pedological processes that influenced the technical success obtained by the interventions. Some critical aspects and possible scenarios of the future evolution of the anthroscapes are also discussed. © Springer-Verlag Berlin Heidelberg 2011.

- Abstract
Depression and posttraumatic stress disorder are two common mental disorders after negative life events. This study was conducted to evaluate the depression and posttraumatic stress levels of pregnant women after the large-scale earthquakes that occurred in Turkey in 2023. The study was carried out with 395 pregnant women who visited maternity outpatient clinics of a public hospital in a province in southern Turkey. The data were collected with the Beck Depression Inventory (BDI) and the Post-Traumatic Stress Disorder Checklist - Civilian Version (PCL-C). Descriptive statistics, the independent-samples t-test, and the Pearson correlation test were used in the analyses of the data. Among all participants, 3.8 percent had a likely depression risk, and 31.9 percent exhibited posttraumatic stress disorder symptoms. A statistically significant relationship was found between the earthquake exposure of the participants and their BDI and PCL-C total scores ( p < .05). The BDI scores of the participants also had statistically significant relationships to their PCL-C scores ( p < .05). In this study, it was discerned that posttraumatic stress disorder symptoms were prevalent among pregnant women in the post-earthquake period. Psychological support is needed to improve the mental health of the pregnant women after earthquakes.

- Abstract
Background: Distal radius fractures have a psychological impact on patients, with the pain and disability caused by these injuries potentially leading to psychological distress. It is not known whether dominant-side and nondominant-side distal radius fractures cause more psychological distress in patients., Questions/purposes: (1) Compared with patients who have distal radius fractures on the nondominant side, do patients with dominant-side fractures experience greater pain? (2) Do patients with dominant-side distal radius fractures have greater disability? (3) Do patients with dominant-side distal radius fractures have worse psychological adjustment? (4) What factors are associated with a worse quality of life mental component measure?, Methods: This retrospective study was conducted by the departments of orthopaedics-traumatology and psychiatry in a multidisciplinary manner at our university hospital, which is a public hospital. The study included 172 patients with distal radius fractures who were treated nonoperatively. We excluded 2% (3 of 172) of patients who underwent surgery because of loss of reduction, 1% (2 of 172) of patients with bilateral distal radius fractures, and 9% (16 of 172) of patients who did not consent to participate in the study. After the exclusion of 12% (21 of 172) of ineligible patients, the study continued with 88% (151 of 172) of patients. Forty-six percent (70 of 151) of patients had dominant distal radius fractures and 54% (81 of 151) of patients had nondominant distal radius fractures. The evaluation was carried out face-to-face at the end of the sixth week of treatment in the orthopaedic outpatient clinic. The VAS score was used to assess pain (this score ranges from 0 to 10, where 0 represents no pain and 10 represents the worst pain, with a minimum clinically important difference [MCID] of 2), the QuickDASH was used to assess disability (ranges from 0 to 100, representing best to worst, with an MCID of 15.9), the Brief Adjustment Scale-6 (BASE-6) was used to assess psychological adjustment (ranges from 6 to 42, lower scores indicate better outcomes), and the SF-12 was used to assess quality of life (ranges from 0 to 100, representing worst to best, with an MCID of 5)., Results: At cast removal, patients with dominant-side distal radius fractures had higher levels of pain (dominant VAS median [IQR] 4 [4], nondominant VAS median 2 [3], median difference 2; p = 0.005), but the difference was not clinically important. There were no differences in disability (dominant QuickDASH median 63.6 [21], nondominant Quick DASH median 59.1 [25], median difference 4.5; p = 0.20). Psychological adjustment was worse in patients with dominant-side fractures (dominant BASE-6 median 22.5 [24.3], nondominant BASE-6 median 15 [23.5], median difference 7.5; p = 0.004). After accounting for variables such as age, occupation, and gender, a better quality of life mental component (SF-12 MCS) was associated with a lower BASE-6 (β = -0.67; p < 0.001) and nondominant fracture (β = -0.16; p = 0.006)., Conclusion: Dominant-side distal radius fractures have a negative impact on the psychological adjustment and quality of life of patients. Patients with dominant distal radius fractures are more susceptible to the development of psychological disorders. Future studies should assess whether providing appropriate counsel at the time of fracture may alleviate the psychological disorders experienced by patients with dominant-side distal radius fractures., Level of Evidence: Level III, therapeutic study., Competing Interests: Each author certifies that there are no funding or commercial associations (consultancies, stock ownership, equity interest, patent/licensing arrangements, etc.) that might pose a conflict of interest in connection with the submitted article related to the author or any immediate family members.

- Abstract
Background: Cesarean sections, which have a high risk of maternal and neonatal complications and increase health expenditures, have become a global problem. Hence, it is extremely important to encourage women to have normal deliveries., Objective: This study was conducted to determine the effects of tele-education given to nulliparous pregnant women based on the health belief model (HBM) on their normal delivery beliefs and tendencies., Methods: This randomized-controlled study was conducted with 149 nulliparous pregnant women. Participants in the experimental group received a tele-education programme in 8 sessions prepared in line with the health belief model regarding normal delivery for 15 days. The data was collected by using the "Pregnancy Information Form" and "Belief Scale for Normal Delivery (BSND)"., Results: After the tele-education programme, the post-test BSND mean score was 89.90±14.10 in the experimental group and 78.80±12.65 in the control group, where the difference between them was significant (p < 0.01). Additionally, the post-test mean scores of participants in the experimental group in all BSND's subdimensions were significantly higher than those of the women in the control group (p < 0.05)., Conclusion: The tele-education given in line with the HBM increased the belief and tendency levels of the nulliparous pregnant women towards normal delivery.

- Abstract
Objective: This study aims to determine the impact of foot massage given to postmenopausal women on anxiety, fatigue, and sleep., Methods: This randomized-controlled study was conducted with 70 women (35 experimental, 35 control) who resided in a village located in Northern Turkey. In the study, the women in the experimental group were given foot massage once every day for 7 days. No intervention was applied to the women in the control group. The data were collected using a Personal Information Form, the Fatigue Severity Scale (FSS), and the Beck Anxiety Inventory (BAI) Descriptive statistics (frequency, percentage distribution, median, and Q1-Q3), χ 2 test, Mann-Whitney U test, and Wilcoxon test were used in the analysis of the data., Results: It was found that the women in the control group had lower pretest BAI scores than those in the experimental group ( P < 0.05), whereas before the foot massage intervention, the women in the experimental and control groups had similar FSS scores and sleep hours ( P > 0.05). After the foot massage, the FSS scores were 2.3 (1.6-3.4) in the experimental group and 5.5 (4.6-6.2) in the control group, the BAI scores were 26.0 (23.0-29.0) in the experimental group and 36.0 (31.0-43.0) in the control group, the daily sleep hours were 8.0 (8.0-10.0) in the experimental group and 7.0 (6.0-8.0) in the control group, and the differences between the groups were statistically significant ( P < 0.001)., Conclusions: It was determined that foot massage applied during menopause increases the average daily sleep duration (hours) and reduces women's fatigue and anxiety levels., Competing Interests: Financial disclosures/conflicts of interest: None reported., (Copyright © 2022 by The North American Menopause Society.)

- Abstract
Aim: This study was performed to assess the impact of a mobile and web-based software system named Midwifery Clinical Automation (EBEKO) and designed by researchers to be used in clinical practices on motivation, time management and anxiety level., Method: The sample of this randomized controlled trial consisted of 60 midwifery students who were randomly and equally assigned to the experimental and control groups. Data were collected between February and May 2019 using "Student Introduction Form", "Motivation Resources and Problems Scale (MRPS)", "Time Management Inventory (TMI)" and "Spielberger's State-Trait Anxiety Inventory (STAI I-II). EBEKO application was designed as a software system ensuring mutual interaction between students and instructors. Students in the experimental group and all instructors of the department of midwifery were trained in terms of using the system. Students were asked to upload the data regarding midwifery care, monitoring and trainings utilized within the clinical practices to the EBEKO. Data uploaded to the system were transferred to the screen designed for the instructors who were in charge. Instructors assessed these forms (for pregnant women/puerperal women/newborns etc.), demanded revisions, approved or returned. Approved forms corresponded to the number of forms needed by the students in the study to graduate. All students in the experimental group used EBEKO system throughout their education period (14 weeks). No interventions were made on the students in the control group. Data were analyzed through the descriptive statistics (frequency, percentage, mean, standard deviation, min-max values), and t-test in the dependent and independent groups., Results: Students in the experimental and control groups were found to have similar motivation, time management and anxiety level prior to the use of EBEKO. However, after the use of the application, the mean post-test motivation and time management scores of the students in the experimental group significantly increased compared to the control group (p<0.001, p<0.05), but no significant difference regarding the anxiety levels was present between the groups (p>0.05)., Conclusion: EBEKO was found to positively affect the motivation and time management of midwifery students., Competing Interests: Declaration of Competing Interest The authors have no funding or other conflicts of interest to disclose., (Copyright © 2022 Elsevier Ltd.

- Abstract
Aim: This study aims to examine pregnancy and birth planning during COVID-19 and the effects of a tele-education offered to pregnant women for this planning process on prenatal distress and pregnancy-related anxiety., Method: The population of this quasi-experimental study was composed of pregnant women who applied for the antenatal education class of a public hospital in the east of Turkey during their past prenatal follow-ups and wrote their contact details in the registration book to participate in group trainings. The sample of the study consisted of a total of 96 pregnant women, including 48 in the experiment and 48 in the control groups, who were selected using power analysis and non-probability random sampling method. The data were collected between April 22 and May 13, 2020 using a "Personal Information Form", the "Revised Prenatal Distress Questionnaire (NuPDQ)" and the "Pregnancy Related Anxiety Questionnaire-Revised 2 (PRAQ-R2)". An individual tele-education (interactive education and consultancy provided by phone calls, text message and digital education booklet) was provided to the pregnant women in the experiment group for one week. No intervention was administered to those in the control group. The data were statistically analyzed using descriptive statistics (frequency, percentage, mean, standard deviation, min-max values) and t-test in dependent and independent groups., Results: The posttest NuPDQ total mean scores of pregnant women in the experiment and control groups were 8.75±5.10 and 11.50±4.91, respectively, whereby the difference between the groups was statistically significant (t=-2.689, p=0.008). Additionally, the difference between their mean scores on both PRAQ-R2 and its subscales of "fear of giving birth" and "worries of bearing a physically or mentally handicapped child" was statistically significant (p<0.05), where those in the experiment group had lower anxiety, fear of giving birth and worries of bearing a physically or mentally handicapped child., Conclusion: The tele-education offered to the pregnant women for pregnancy and birth planning during COVID-19 decreased their prenatal distress and pregnancy-related anxiety., Competing Interests: Declaration of Competing Interest The authors have no funding or other conflicts of interest to disclose., (Copyright © 2020 Elsevier Ltd.

- Abstract
Background: Oxytocin is widely used in perinatal medicine, but it can cause serious side effects. Health professionals should be familiar with the pharmacokinetics, dosing regimen, and fetal effects of oxytocin. This study aims to explore the use of oxytocin by healthcare professionals during labor., Methods: This study was conducted in one medical faculty, one training and research hospital, one maternity hospital, and one private hospital in Adana, Turkey. The sample group included 107 participants. The data were gathered using a survey prepared in line with the literature. The survey was comprised of 30 questions. These questions concern the social demographic information of the participants, the knowledge and actual oxytocin use, and the views of the participants. The data were analyzed using descriptive statistics., Results: The average age of the participants was 36.76 ± 8.70 years, the mean of working experience in the delivery room was 7.79 ± 7.73 years. 85.6% of the participants who answered the question of possible effects of oxytocin as contraction, 57.9% of the possible side effects as fetal distress. 69.2% of the participants stated that they applied oxytocin after dilution in a fluid while 47% stated that they applied it after dilution in fluid with 5% Dextrose. While 40% of the participants responded that they sometimes forgot to administer medication, 39.2% stated that they did not register medication in their survey responses., Conclusion: It was determined that most of the participants answered the questions about the effect of oxytocin correctly, but they could not respond to all the side effects of oxytocin. It was found that most of the participants could not answer the storage conditions that are important for the effectiveness of the drug correctly. In addition, the importance level given to the principles of drug administration by the participants was generally found to be high., Competing Interests: The authors declare no conflict of interest., (©2020 Tottori University Medical Press.)

- Abstract
Time series model selection has been widely studied in recent years. It is of importance to select the best model among candidate models proposed for a series in terms of explaining the procedure that governs the series and providing the most accurate forecast for the future observations. In this study, it is aimed to create an algorithm for order selection in Box-Jenkins models that combines penalized natural logarithm of mutual information among the original series and predictions coming from each candidate. The penalization is achieved by subtracting the number of parameters in each candidate and empirical information the data provide.Simulation studies under various scenarios and applications on real data sets imply that our algorithm offers a promising and satisfactory alternative to its counterparts., Competing Interests: No potential conflict of interest was reported by the authors., (© 2020 Informa UK Limited, trading as Taylor & Francis Group.)

- Abstract
This multidisciplinary research work evaluated the effects of soil erosion on grape yield and quality and on different soil functions, namely water and nutrient supply, carbon sequestration, organic matter recycling, and soil biodiversity, with the aim to understand the causes of soil malfunctioning and work out a proper strategy of soil remediation. Degraded areas in nineteen organically farmed European and Turkish vineyards resulted in producing significantly lower amounts of grapes and excessive concentrations of sugar. Plants suffered from decreased water nutrition, due to shallower rooting depth, compaction, and reduced available water capacity, lower chemical fertility, as total nitrogen and cation exchange capacity, and higher concentration of carbonates. Carbon storage and organic matter recycling were also depressed. The general trend of soil enzyme activity mainly followed organic matter stock. Specific enzymatic activities suggested that in degraded soils, alongside a general slowdown in organic matter cycling, there was a greater reduction in decomposition capacity of the most recalcitrant forms. The abundance of Acari Oribatida and Collembola resulted the most sensitive indicator of soil degradation among the considered microarthropods. No clear difference in overall microbial richness and evenness were observed. All indices were relatively high and indicative of rich occurrence of many and rare microbial species. Dice cluster analyses indicated slight qualitative differences in Eubacterial and fungal community compositions in rhizosphere soil and roots in degraded soils. This multidisciplinary study indicates that the loss of soil fertility caused by excessive earth movement before planting, or accelerated erosion, mainly affects water nutrition and chemical fertility. Biological soil fertility is also reduced, in particular the ability of biota to decompose organic matter, while biodiversity is less affected, probably because of the organic management. Therefore, the restoration of the eroded soils requires site-specific and intensive treatments, including accurately chosen organic matrices for fertilization, privileging the most easily decomposable. Restoring soil fertility in depth, however, remain an open question, which needs further investigation., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

- Abstract
Regular crystalline surface layers (S-layers) are widespread among prokaryotes and probably represent the earliest cell wall structures. S-layer genes have been found in approximately 400 different species of the prokaryotic domains bacteria and archaea. S-layers usually consist of a single (glyco-)protein species with molecular masses ranging from about 40 to 200 kDa that form lattices of oblique, tetragonal, or hexagonal architecture. The primary sequences of hyperthermophilic archaeal species exhibit some characteristic signatures. Further adaptations to their specific environments occur by various post-translational modifications, such as linkage of glycans, lipids, phosphate, and sulfate groups to the protein or by proteolytic processing. Specific domains direct the anchoring of the S-layer to the underlying cell wall components and transport across the cytoplasma membrane. In addition to their presumptive original role as protective coats in archaea and bacteria, they have adapted new functions, e.g., as molecular sieves, attachment sites for extracellular enzymes, and virulence factors.

- Abstract
The archaea are recognized as a separate third domain of life together with the bacteria and eucarya. The archaea include the methanogens, extreme halophiles, thermoplasmas, sulfate reducers and sulfur metabolizing thermophiles, which thrive in different habitats such as anaerobic niches, salt lakes, and marine hydrothermals systems and continental solfataras. Many of these habitats represent extreme environments in respect to temperature, osmotic pressure and pH-values and remind on the conditions of the early earth. The cell envelope structures were one of the first biochemical characteristics of archaea studied in detail. The most common archaeal cell envelope is composed of a single crystalline protein or glycoprotein surface layer (S-layer), which is associated with the outside of the cytoplasmic membrane. The S-layers are directly exposed to the extreme environment and can not be stabilized by cellular components. Therefore, from comparative studies of mesophilic and extremely thermophilic S-layer proteins hints can be obtained about the molecular mechanisms of protein stabilization at high temperatures. First crystallization experiments of surface layer proteins under microgravity conditions were successful. Here, we report on the biochemical features of selected mesophilic and extremely archaeal S-layer (glyco-) proteins.

- Abstract
Dental implants and their successful long-term results have begun a new era in dentistry. In recent years, the increasing trend of using dental implants at single-tooth edentulous cases has been taken into consideration. Although treatment goals and objectives are similar for both prosthodontists and orthodontists, they rarely cooperate.
