The article is dedicated to cave drawings from Shakhty and Kurteke sites located in the high mountain areas of the Pamir. The main studies at these sites were carried out by V. A. Ranov in the late 1950s and 1960s of 20th century. The re-documenting of these drawings in 2019 and the processing of the received photographs by DStretch refined the contours and details of some images, important for attribution and subsequent interpretation. These data called into question some of the earlier analogies from rock art of adjoining territories, and also allowed to attract new analogies. On the basis of the analysis of sources, the possible chronological boundaries of the creation of rock drawings in the Eastern Pamir were clarified. It is assumed that images of the Shakhty rock-shelter can be dated within the range of Mesolithic to the Bronze Age. Some of the drawings of the Kurteke may be attributed to the Bronze Age, but this does not preclude an earlier date of the rest of the imagery of the site.

Success is a concept that is desired by everyone. In the Turkish education system, Anatolian high schools are considered one of the most prestigious schools which accept students via national central exams. The purpose of this study is to reveal indicators explaining the placement into Anatolian high schools, which is an important sign of success, in socioeconomically different regions. Logistic regression analyses were used as a prediction design. Data was collected from the 1049 10th grade high school students in Istanbul. According to findings, the indicators affecting the probability of studying in Anatolian high school differ between the low life quality indexed region (LLQR) and the high life quality indexed region (HLQR). In LLQR GPA, gender, number of people in the household, and mother’s monetary contribution were found as significant indicators. In HLQR GPA, father’s income and mother’s education level were found as significant indicators. These results are discussed using the main theories of educational sociology.

We present the case of a 65 years- old woman who was admitted with a severe macrocytic anemia Hb= 5.7g/dl and diffuse bone pain. Biologically she has moderate thrombocytopenia 35 000/µl, a hepatic cytolysis and cholestatic syndrome. Material and method: The patient was extensively evaluated before presentation for a mild iron - deficiency anemia for which she underwent endoscopic examination of the upper and lower gastrointestinal tract- normal. The bone marrow aspiration on admission revealed a marked hyperplasia of the erythroblastic line with ~50% basophilic erythroblasts suggesting a regenerative erythroid hyperplasia. These changes along with the marked reticulocytosis on the peripheral blood smear oriented us towards a hemolytic anemia; Folic acid, vitamin B12, autoimmune tests and hemolytic tests were all normal. We continued the investigations with a thoraco-abdominopelvic computed tomography which identified diffuse demineralization, vertebral compactation and pelvic stress fractures. The breast examination revealed a right breast nodule, but the breast ultrasonography pleaded for benignity. Lacking a clear definitive diagnosis we decided to perform a bone marrow biopsy. Results: The osteo- medullary biopsy pointed towards a medullar invasion from a lobular mammary carcinoma; In these circumstances we performed an ultrasound guided biopsy of the right mammary lump thus histologically confirming a tumoral invasion of the bone marrow with subsequent anemia. The patient started chemotherapy in the Oncology ward. Conclusion: The particularity of this case consists in the pattern of anemia, which initially seemed iron deficient and afterwards macrocytic – apparently hemolytic and was actually due to the tumoral medullar invasion and also the nonspecific ultrasonographic appearance of the breast tumor.

Evidenced-based medicine drives best practices. The Lessons Learned (LL) process in clinical medicine for deployed and military support services drive the NATO Military Medical Center of Excellence (MILMED COE). This review article focuses on the Lessons Learned process and its use in NATO and partner countries medical services. Organizational learning drives development and progress; capturing lessons from mistakes, colleagues’ interactions and institutional experience can be lost without an organized lesson learned process. Therefore, in 2014, NATO institutions and Centers of Excellence across disciplines began to focus on the quality management, information sharing and evidence-based practices to maximize outcomes. Since this inception, NATO has implemented the Lessons Learned process and expanded the impact across the alliance in order to save life and prevent illness. The Lessons Learned process and sharing of experience is also a way to improve the quality of care in the military medicine, from preventive, epidemiological, trauma related, casualty evacuation and forward surgical care, among many others, to the medical standardization and organization of military medical services. The Lessons Learned process is an undertaking and an instrument that can also be used to achieve better international and civil-military cooperation. Finally, we deal with the current situation and use of the information obtained from the areas of military health care.

The prognosis of patients with Zenker`s diverticulum is dependent mainly on the type of procedure performed, either surgical or rigid/flexible endoscopy. Purpose - evaluation of the redo procedure by reviewing correlations in patients with iterative procedures. Material and Methods: We included in the study 36 patients with cervicomediastinal Zenker diverticula treated from 2010 to 2017 at two university hospitals: Clinic of General and Esophageal Surgery. Mary Clinical Hospital Bucharest and Department of Diagnostic and Interventional Digestive Endoscopy of the Regional Institute of Hepatology and Gastroenterology Prof. Dr. Octavian Fodor, Cluj-Napoca. For the patients included in the study we studied correlations of patients with symptoms persistence and to those with reintervention with epidemiological, clinical and the treatment criteria. Results: Postprocedural symptoms we observed in 5 patients of the 29 treated endoscopically and 6 of the seven treated surgically. Statistical correlations were noted in patients with persistent symptoms after surgical treatment (p <0.01) with patients with diverticulectomy (54.5%) (p <0.01), grade III diverticula (36.4%) (p <0.01) statistical association was noticed in patients who have required reoperation and those with persistent symptoms (63.6%) (p <0.01) and with remaining dysphagia (100%) (p <0.01) and those with grade 2 dysphagia persistence (71.4%) (p <0.01), grade 3 diverticula (42.9%) (p <0.03) and the high number of comorbidities. (p <0.04) Conclusion: Undoubtedly, endoscopic treatment is being used more and more even for those cases that require further treatment. Reoperation has been necessary for patients with persistent dysphagia with voluminous diverticula and a high number of comorbidities.

Obesity correlates with a higher risk of fractures in some sites as vertebras, upper arm, and legs. This is a narrative mini-review focused on several key points that link obesity with osteoporosis. Waist circumference may a better predictor of fractures than body mass index (BMI) in obese females. Even obese menopausal women have an extra source of estrogens in fat tissue this actually is not enough to offer a complete protection against osteoporotic fractures. Low levels of testosterone in males induce a higher risk of fall dependent or independent of sarcopenia (which is more evident in elderly). High BMI is correlated with vitamin D deficiency. Obesity is a contributor to muscle damage and decline due to fat accumulation and inefficient fuel utilisation by the muscle, namely sarcopenic obesity, regardless the age. Associated type 2 diabetes mellitus involves bone damage and fracture risk due to glycated proteins of the matrix, the changes of adipokines, increased cortical porosity, high risk of fall because of blood pressure and glycaemia anomalies, visual disturbances, renal and peripheral nerves diabetes-associated conditions etc. The fracture risk is also augmented via fat derived cytokines and chronic inflammation. Even it seems logical that the weight correction though bariatric surgery reduces the fracture risk in obesity, actually data from longitudinal studies pointed that, despite the procedure is life saving, it does not actually protect against osteoporosis which is regarded as a potential long-term complication. A high fracture burden in obesity should increase the level of awareness for practitioners of different medical areas due to multiple levels of complications and to the epidemiological impact of obesity.

The pneumatization of all nasal turbinates is an extremely rare finding. Several previous reports have presented the bilateral superior, middle, and inferior conchæbullosæ. We report the bilateral pneumatization of middle and superior nasal turbinates. The variant was documented in cone beam computed tomography (CBCT) in all three dimensions. The inferior concha bullosa was a bilaterally moderate subtype of lamellar pneumatization that presented as a conchal recess of the maxillary sinus. The concha bullosa media was bilaterally of the extensive or true type and associated unilaterally with an uncinate bulla. The concha bullosa superior was asymmetrical bilaterally, narrower on the right side, and larger on the left where it was also septated and tri-cameral. The supreme conchæ were rudimentary, as were their pneumatizations. For an accurate anatomic diagnosis of conchæbullosæ in computed tomography, sagittal, coronal, and axial cuts, as well as three-dimensional reconstructions, should be used to ensure adequate planning of functional endoscopic sinus surgery.

One of the most obvious trends in current prosthetic dentistry is the introduction of digital techniques. Of these, the techniques that offer the possibility of aesthetic prefiguration of the final prosthetic result are of particular interest to the dentist. The aim of this paper was to verify the applicability of the Digital Smile Design application, which is the most commonly, used aesthetic prefiguration application, an application designed for the dentate patient, to full edentulism. Two groups of full edentulous patients were formed: the first group, complete denture carriers, dissatisfied with the aesthetic aspects, that they wanted to improve in the new denture, and, the second group, newly bimaxillary full edentulous patients with high aesthetic expectations. Thus, on the first group, the tests were performed on the existing denture, and the second one with the maxillary occlusion template. However, the view of the final result offered the patients the chance to have a realistic picture of their desires regarding the shape, color, size of the teeth, which were inadequate in relation to age and facial typology. The use of this application also improves communication with the dental laboratory. In full edentulism, the current DSD technique can be used with some limitations and the use of it in this field needs more complex studies on larger groups of patients.

Published: May 2022

Background: Cholera is a preventable disease, still it remains a major public health problem among developing countries like India. Access to safe water and a sanitary environment can easily control many gastrointestinal infections including Cholera. In the last week of June 2021 large number of acute diarrhoeal cases were reported which was higher than expected subsequently confirmed as an outbreak of Cholera.

Objective: To verify the diagnosis, identify risk factors and institute appropriate control measures to control the outbreak.

Materials and Methods: A cross-sectional study was undertaken to identify the time, place and personal distribution of the disease. Based on the findings of the descriptive study, sanitary survey and environmental examination a hypothesis was formulated. A case-control study was carried out to test a hypothesis

Results: A total of 158 cholera cases were reported with one death. Male and females were affected equally. All age groups affected, 18.35% of the cases were reported among children aged 0-5 years old. It was a common source epidemic and water was source of infection. The water sample reported faecal contamination. Those households not using water purification methods were 1.454 times more affected (OR=1.454) than those using water purification methods.

Conclusion: The Vibrio Cholerae bacterium caused the cholera outbreak in Nadiad. Infection was caused by contaminated drinking water.

Published: May 2022

Background: With aging process, cognitive levels decline which has affected nearly 50 million people worldwide. In view of this, our study aims to estimate the prevalence of cognitive impairment and its correlation with co morbidities among the elderly residing in old age homes in Southern India and determine its various risk factors among them. Methodology: This cross-sectional study was carried among 330 elderly living in old age homes by using multistage sampling method. Study population included Elderly above the age of 60 and residing in old age homes, who were willing to participate. A pretested structured questionnaire was used. Data was analysed using SPSS. Results: Of the 330 participants, nearly 44% had mild to moderate and 36% had severe cognitive impairment. The odds of developing cognitive impairment were 2.5 times more among individuals who had at least one feature of dementia when compared with those who did not have any symptoms. Conclusion: The strategies of National Programmes for Health Care of Elderly and National Mental Health Program do not cater specifically to cognitive impairment. Level of attention given towards Alzheimer’s disease is more when compared to screening for cognitive impairment which is an early precursor for Alzheimer’s disease.

Published: May 2022

Energy is a sector of production of considerable interest. Today's era is particularly dependent on energy. Both continuous technological upgrading and the increase in living standards require ever-greater energy security. Many countries in the world are formulating their policies in order to secure energy resources. Energy security is one of the most important objectives of any country in the international economic system. All countries are trying to secure energy resources whether they are endowed or through trade. However, the main issue that arises is the production of energy. Energy production has a direct and indirect impact on a country's economy. It is therefore essential to properly investigate those factors that determine energy production. What are those factors determining energy production? There are many factors that can determine energy production. This study will attempt to set an analytical framework that can analyze the factors that determine energy production. The methodology applied is the construction of a composite index (CI).

Improving Quality of Arabic Dates by low Doses of Irradiation
Authors: Serag Farag
Published: May 2022

This work  aim to select the optimum dose of γ-rays for  keeping  quality of semi dry  dates(SDD) through studying physical, chemical ,microbiological characters besides disinfestations of dates. Three Arabic SDD varieties as Siwi (Egypt), Sukkary (Saudi Arabia) and Zahidi (Iraq) at ‘Tamar’ stage were  irradiated with γ-rays (0.0,1.0, 3.0  5.0 kGy).The storage of  packaged treated samples was extended eight months at room temperature (20 ~25 C°, 70~75%RH). The free radicals was monitored by Electron Spin Resonance (ESR), survey insects and microbes. Besides, tracking the changes of bioactive content (amino acid- AA, sugars and Soluble Solid Contents -SSC). Results revealed that ESR-signals of   edible parts were completely disappeared after one month whereas it’s present in kernels. Also, irradiation eliminated completely all stages of insects and reduced the microbial load either fungi or bacteria. HPLC- analysis of AA showed presence of seventeen one (µg/g dry weight), in all tested samples, the difference occurred due to variety and irradiation dose. Sugars were accumulated at end of   storage (8 months), whereas negligible changes were recorded in total, reducing or non-reducing sugars but were significantly between varieties. Same trends were noticed in SSC. At the end, the preferability  of using low dose  of γ–irradiation are suitable on large scale, safe alternative for using pesticides and sufficient for  keeping quality of tested  Arabic  semi dry dates without high losses in nutritive values.

Published: May 2022

Grapevine is an important fruit crop grown in the Chott Sidi Abdel Salam oasis in south eastern Tunisia. It provides great economic potential for the oasis population due to its higher yield and monetary returns. It, also, has a good nutritional value and is consumed fresh or in dried form. Powdery mildew represents one of the most destructive diseases affecting viticulture, especially in temperate-humid climate. It is an economically important fungal disease in the grapevine farms. This pathogen is able to differentially attack leaves and grapes, and is currently controlled with repeated applications of fungicides. This research aimed to use chemical control in order to assess the ability of contact, systemic and the combination of both routes of fungicides’ administration, at three different sampling moments to manage powdery mildew infestation of grapevines (Cv. Bazzoul Kalba), under field conditions. The experiments were conducted in the oasis of Chott Sidi Abdel Salam in southeastern Tunisia. Both Pristine WG and Vectra 10 SC allowed controlling the disease intensity of powdery mildew compared to Talendo® showing a highly significant augmentation of the inhibitory growth potential (84.26% and 88.94%, respectively at 21 days after the first fungicide application) and the protective potential (73.11% and 76.92%, respectively at 21 day). This information can be used to help grapevines growers to improve powdery mildew control and enhance marketable yields.

In this study, we analyzed salt tolerance in two varieties of Medicago sativa at the vegetative stage. Gabès2355 and Californian varieties of M. sativa were cultivated under control treatment and under a range of salt concentrations (50 mM, 100 mM, 150 mM, and 200 mM NaCl) in a greenhouse. At harvest, ten quantitative characters related to aerial and root growth were measured for plants of both varieties. Results from ANOVA showed that the variation of the traits measured is explained by the effects of variety, treatment and the interaction of variety x treatment. The treatment factor represents the most pronounced effect. While the Californian variety was more sensitive than the Gabès variety under 50 mM NaCl, it was the most tolerant under higher concentrations of NaCl. Specific correlations between measured traits were noted under control treatment and salt stress. Further work is needed to evaluate the agronomic performances of both varieties in the field under salinity constraint.

Quinoa is a pseudo-cereal native to the Andes known for its exceptional adaptation to extreme soil and climate conditions. The study of the response of Chenopodium quinoa to osmotic stress and the contribution to improving its yield aims to ensure production in arid and semi-arid regions as an alternative crop. The aim of this study is to test the germination capacity of 5 selected varieties; CQ-57, UDEC-2; ICBA-4, ICBA-5 and 115-R subjected to varying osmotic pressures using solutions of PEG-6000 and NaCl. Seeds are incubated at 25 °C for 10 days. Results showed that osmotic stress increases the lag phase but does not affect the germination rate at low concentrations of PEG and NaCl. While for high concentrations the germination rates decrease as compared to controls. Radicale and hypocotyl lengths decreased with increasing the degree of osmotic stress. The effects of osmotic stress are comparable in the 5 varieties. At high concentration of PEG or NaCl, ICBA-5 and CQ-57 exhibited the highest value of germination rate showing the capacity of these varieties to establish itself in regions suffering from salinity or water deficit.

Zea mays L. (maize) is one of the top three cultivated cereals globally, along with wheat and rice. The United States, China, and Brazil are among the largest producers of maize, producing approximately 79% of the world’s maize. Maize is used to produce human food and animal feed. It is also used to produce industrial products such as starch sweeteners, oil, beverages and bioethanol. South Africa produces maize as well. However, this production is relatively insignificant compared to the major producers. Furthermore, South Africa is a semi-arid country and as such receives less rainfall and has annual droughts. This has negative implications on maize production, which threatens food security. The sole reliance on a limited number of staple cereals is not a sustainable option. In order to truly improve food security, the diversification of staple cereals is necessary. Therefore, this review aims at discussing the diversification of staple cereals in southern Africa, specifically focusing on sorghum, pearl millet, finger millet and teff. These African indigenous cereals are known for their environmental resilience as well as having nutritional benefits. Southern Africa will experience more droughts in the future as a result of climate change, which will undoubtedly impact maize yields. Therefore, it is important that efforts are intensified to ensure that indigenous drought-adapted crops are fully exploited to improve future food security.

Due to its very important agronomic value and nutritional quality, Medicago sativa L. is considered as the queen of fodder and the first cultivated forage crop in the world. In field conditions, M. sativa is exposed to several biotic and/or abiotic constraints that affect its quality. In this regard, research is still underway to improve M. sativa resistance to many biotic stresses and, in this context, we analyzed the responses of a core collection of 10 varieties of M. sativa to Phoma medicaginis infection. Results from ANOVA showed that most growth parameters exhibited significant differences between the studied varieties. Nevertheless, only the number of healthy leaves among infection parameters varied significantly between the varieties. The local variety Gabès2355 exhibited the highest biomass. Positive correlations were found between the measured parameters. PCA based on the traits showing significant differences among the studied lines showed that the Gabès variety formed a separate group. Cluster analysis revealed that the studied varieties are classified into three major groups. The first group is formed by Gabès2353, the second group is composed of the Californian and El Hamma varieties, and the third group is constituted of the seven remaining varieties. Gabès2355 was the most tolerant to the Pm8 strain of P. medicaginis while Magna601 variety was the most susceptible. These two varieties will be useful to analyze the physiological and genetic determinants for M. sativa tolerance to P. medicaginis infection.

The seed- borne pathogen Pyrenophora graminea Ito& Kur. is the causal agent of barley leaf stripe, a destructive disease in most barley growing region in the world. In order to  improve the barley species in Algeria against this disease, it is necessary to know their tolerance reaction  to it. The genotype that have been tested are five parent genotypes: ACSAD,  Tichedrett,  Saida,  Rihane,  Hamra and eight populations hybrid obtained by intraspecific crosses of the parents and then sowing of F1 to F8. We compared the incidence of the isolate of Pyrenophora graminea  for morphological characters (Stem height) and yield (1000-grain weight, medium yield of plant) of the studied variety. The results obtained showed the existence of variability between our thirteen genotypes of barley which had a different resistance level in the quantitative and qualitative characters.

Nowadays, pea field is getting more attention because of its nutritional values.  The objective of this paper is to characterize and identify relationships among 21 Mediterranean pea accessions.  Fifteen accessions of Pisum sativum subsp. elatius and six accessions of Pisum sativum subsp. arvense were provided by ICARDA (International Centre for Agricultural Research in Dry Areas). Twenty qualitative traits were selected according to the guidelines of the International Union for the Protection of New Varieties of Plants (UPOV). We measured eight vegetative qualitative traits such as presence or absence of leaflets, type of plant axis development and presence or absence of anthocyanin coloration. We measured twelve floral qualitative traits such as standard color, pod color and curvature of the pod. In order to study the clustering of our accessions, we used Past4.03 with the test UPGMA (unweighted pair group method with arithmetic mean). The biometric and descriptive analysis we carried out reveals the presence of traits that discriminate accessions. Among these traits, we can cite C15 (vegetative qualitative trait), C23, C31 and C35 (floral qualitative traits). C15 discriminates the accessions TUR10, TUR8, SYR1 and SYR2. C23 distinguishes TUR6, TUR11 and AL2 accessions from other accessions. C31 is a discriminating trait for TUR13 accession. The type of starch grain (C35) discriminates the TUR14 accession. Cluster analysis led to establishing dendrogram allowing a grouping of accessions according to their geographical affiliation. In fact, it is possible to discriminate significantly the accessions TUR10, SYR1 and SYR2 from the accessions TUR12, TUR13, GR1 and TUN which could be an incentive for further improvement and better exploitation.

Experimental models provide a deeper understanding of the different pathogenic mechanisms involved in Demyelinating disorders. The development of new in vitro and in vivo models or variations of existing models will contribute to a better understanding of these diseases and their treatment. Experimental models help to extrapolate information on treatment response. Indeed, the choice of the experimental model strongly depends on the research question and the availability of technical equipment. In this chapter, the current in vitro and in vivo experimental models to examine pathological mechanisms involved in inflammation, demyelination, and neuronal degeneration, as well as remyelination and repair in demyelination disorders are discussed. We will also point out the pathological hallmarks of demyelinating disorders, and discuss which pathological aspects of the disorders can be best studied in the various animal models available.

Diabetes mellitus is one of the most common medical disorders often associated with neurological complications. Peripheral neuropathy is the most common neurological complication from diabetes with a prevalence of 10–26% of newly diagnosed adult diabetics. Diabetic neuropathy is a heterogeneous group of conditions that present with sensory and/or motor and/or autonomic dysfunction and affect different parts of the peripheral nervous system. Diabetic neuropathy might present as a polyneuropathy, mononeuropathy, mononeuropathy multiplex, radiculopathy, and/or plexopathy. Diabetic neuropathies may also be associated with foot ulcers and infections in 5–24% of patients, which translate into five out of 1000 of diabetics ending with an amputation. Therefore, it is essential to screen diabetic patients for early recognition and management of diabetic neuropathies.
