Absorption of foliar-applied lead (Pb) in rice (Oryza sativa L.): A hydroponic experiment
(Parlar Scientific Publications, 2018) Sardar M.F.; Ahmad H.R.; Zia-Ur-Rehman; Ozturk M.; Altay V.
Metallic particulate matter has been released into the environment that can be deposited on aerial parts of vegetation in terrestrial ecosystems. Foliar transfer of metals and their fate in plant leaves is still unclear although it is contributor to the transfer of metals into plant body. The study was conducted with the objective of investigating the possible effects of various concentration levels (0, 10, 20, and 30 mg L-1) of foliar-applied Pb on rice (Oryza sativa L.) grown in half strength Johnson's nutrient solution. The results showed that increasing levels of lead application decreased fresh and dry weights of rice compared with control. Lead concentrations in roots increased with increasing rate of application. The overall results indicated bioaccumulation of foliar applied lead in rice plants. © by PSP.

Assessment of biodiversity differences between natural and artificial Wetlands in Cyprus
(2012) Gucel S.; Kadis C.; Ozden O.; Charalambidou I.; Linstead C.; Fuller W.; Kounnamas C.; Ozturk M.
Despite being a dry country, historically, Cyprus had many wetlands, both freshwater and saline. However, pollution, mosquito management, increased use of water and drainage of wetland areas for agriculture and building, led to the loss of many of the original wetlands. On the other hand, persistent water shortages have led to the construction of more than 100 dams on the island. In this study, the biodiversity of two natural wetlands, Ronnas River and Oroklini Lake, was compared to that of two man-made wetlands, Geçitköy (Panagra) Reservoir and Achna Dam. Baseline ecological surveys of plants, invertebrates and birds were carried out at bi-monthly intervals from February to June 2006. In total, 495 plant species, out of which 22 were endemic, were recorded with Gecitkoy (Panagra) Dam showing the highest plant diversity and Oroklini Lake the lowest. A total of 13 invertebrate orders were recorded, however, no statistical difference was found between the number of orders in artificial and natural wetlands. Furthermore, 18 butterfly species were recorded, with the highest diversity found at Ronnas River on Centaurea sp., Onopordum cyprium, Pistachia sp. and Cistus creticus. Less diversity found at Oroklini Lake and Achna Dam was due to an absence of maquis vegetation in these areas. Moreover, the highest butterfly diversity in all wetlands was observed in February and April, following winter rainfall in February, and increasing temperatures in April. Lower insect numbers and diversity in May were due to windy conditions. A total of 83 bird species were identified, with 32 recorded at Ronnas River, 29 at Oroklini Lake, 25 at Geçitköy (Panagra) Reservoir and 35 at Achna Dam. Most individuals were counted at Achna Dam (1493) and the least at Ronnas River (217). At Oroklini, Geçitköy and Achna, the most abundant species was the Common Coot while most species recorded at Ronnas were terrestrial, with the Common Wood-pigeon being the most abundant species. However the outcome so far is that there is little difference between these two wetlands types in terms of biodiversity richness. This study has demonstrated that artificial wetlands do provide important habitats for flora and fauna and these sites should be managed with biodiversity as well as water resources.
Assessment of genetic diversity among hybrid pea lines (Pisum sativum L.) as revealed by random amplified polymorphic DNA (RAPD) markers
(Parlar Scientific Publications, 2018) Iqbal A.; Razzaq A.; Hadi F.; Nisar M.; Ozturk M.; Altay V.
Information about genetic diversity among pea genotypes of Pakistan is limited. Molecular marker analysis is an important technique in analyzing the genetic diversity among pea providing useful information to broaden the genetic base of pea lines. The objective of this study was to evaluate the genetic diversity among 24 hybrid pea lines using random amplified polymorphic DNA (RAPD) technique. A total of 69 DNA fragments were generated by 20 RAPD markers, with an average of 3.45 cleanly detectable alleles per primer. Of these, 67 fragments (97.10%) were polymorphic among the total pea lines. Molecular weights of alleles ranging from 250 bp to 2000 bp. The minimum alleles (1) were amplified by the primer OPA 17. Whereas, maximum alleles (6) were amplified by primers OPA-13, OPA-19, OPA-20, OPB-11 and OPB-14 each. The average alleles/locus primer-1 was 3.45 and overall polymorphism was 97.10% that gave a promising indication to broaden the research horizon for investigation of genetic diversity in pea and only 2.9% bands showed monomorphic behaviour. The similarity indices based on all possible pairs of lines ranged from 0.43 to 0.92. The minimum similarity value of 0.43 was observed between PL-6 and PL-22 Similarity, closer to unity was observed between PL-11 and PL-15 (0.92). The results of the present investigation using RAPD markers have successfully revealed an informative DNA polymorphism among pea lines, which could be included into marker-assisted selection and breeding programs aspiring at genetic improvement of this nutritionally important crop species. © by PSP.
A biomonitor of heavy metals on ruderal habitats in Turkey -Diplotaxis tenuifolia (L.) DC.
(2013) Ozturk M.; Sakcali S.; Celik A.
Diplotaxis tenuifolia is a medicinally important perennial plant species, distributed widely alongside the roads in Turkey. The samples were collected from 54 sites, including highways, sideways, industrial areas, urban centres and rural environs. Both the plant and soil samples were analysed to determine the concentrations of different metals using AAS. The results showed that in the soil samples copper and lead were highest near highway 45.533 and 2.865 mg/kg, respectively; but lowest values of copper were determined around industrial areas (3.514 mg/kg), latter however showed higher concentrations of cadmium (0.726 mg/kg) and iron (82.766 mg/kg). The lead as well as iron were the lowest around sideways 1.917 mg/kg and 54.073 mg/kg, respectively, whereas chromium concentrations in the soils were highest near sideways (18.397 mg/kg) and lowest around industrial areas (0.182 mg/kg). The sideways showed very low nickel concentrations (0.271 mg/kg), as compared to the rural areas which had higher nickel concentrations (0.726 mg/kg). No cadmium was detected in the urban soil samples. In the plants copper and chromium were higher in the urban areas 50.130 and 0.238 mg/kg, respectively. The former was lowest around sideways (32.377 mg/kg) and latter around highways (0.114 mg/kg). Both nickel and cadmium were higher in the samples from industrial areas 0.238 and 0.016 mg/kg, respectively. Their values around the highways were lowest 0.182 and 0.005 mg/kg. The samples from urban sites revealed highest values of lead (3.474 mg/kg) and iron (61.304 mg/kg), but the values of lead were lowest around sideways (2.420 mg/kg) and those of iron in the vicinity of industrial areas (20.600 mg/kg). All these findings depict that there is some aerial deposition of these metals on the leaves. A significant correlation is seen between the plants and the soils.
Boron and plants
(Springer Netherlands, 2010) Ozturk M.; Sakcali S.; Gucel S.; Tombuloglu H.
Boron is found naturally in the earth's crust in the oxidized form as borax and colemanite, particularly in the oceans, sedimentary rocks, coal, shale, and some soils. It is never found in the elemental form in nature possessing a complex chemistry similar to that of silicon, with properties switching between metals and non-metals. Boron has become an important and strategic element in terms of developing technologies. It is released into the environment mainly through the weathering of rocks, volatilization from oceans, geothermal steam, burning of agricultural refuse and fuel wood, power generators (coal/oil combustion), glass industry, household use of boron-containing products (including soaps and detergents), borax mining and processing, leaching from treated wood and paper, chemical plants, and sewage/sludge disposal, but a major proportion originates from the weathering of rocks. Boron is regarded as an essential element for human beings, animals and plants. Boron occurs in soils at concentrations ranging from 10 to 300 mg kg-1 depending on the type of soil, amount of organic matter, and amount of rainfall. The treatments lead to significant increases in the productivity of some plants but in certain cases a decrease is seen as the boron level increases with the boron content of irrigation water, in particular on the soils with a heavy texture, high CaCO3 and clay content. Lack of boron in plants results in necrosis but excess amounts are said to produce poisonous effects. Turkey produces more than 60% of the world's borax, with important boron reserves located in Susurluk, Bigadic and Sindirgi regions of Balikesir, Kestelek-Bursa, Emet-Kutahya, the largest reserves occur in Kirka-Eskisehir. Therefore, there is a naturally occurring high level of boron in the ground waters in some of these areas due to the excess amounts of boron given out to the environment during washing and purification processes which result in the pollution of cultivated areas. An attempt will be made here to present an overview of the plant diversity on the boron contaminated soils in Turkey, effects of different concentrations of boron on the germination ability of some plants and possible candidates for phytomining of the soils showing boron toxicity symptoms. © Springer Science+Business Media B.V. 2010.
Carolina poplar (Populus x canadensis Moench) as a biomonitor of trace elements in Black sea region of Turkey
(Triveni Enterprises, 2010) Celik S.; Yucel E.; Celik S.; Gucel S.; Ozturk M.
In this study, the leaves, bark and the soil supporting Populus x canadensis Moench were tested as a possible biomonitor of trace element pollution in the Middle Black Sea region of Turkey. The investigations were carried out at 23 sites. The leaves, bark and soil were analyzed for Pb ++, Cd++, Fe++, Cu++ and Zn ++ contents. The values of Pb++, Cd++, Fe ++, Cu++ and Zn++ in the leaves varied between 14.5-40.0, 0.5-1.5, 135-486, 5.0-14.0 and 43-246 ppm, respectively. In the bark the values were between 15.5-36.5 (Pb++), 1.5-2.0 (Cd++), 39-575 (Fe++), 5.0-14.0 (Cu++) and 40.0-1468 ppm (Zn ++), whereas in the soil values for Pb++ were 1.0-4.1 ppm, for Cd++ 0.2 ppm, for Fe++ 0.6-1.8 ppm, for Cu ++ 0.1-0.9 ppm and for Zn++ 0.1-1.9 ppm. A positive correlation was found between traffic density and the amount of Pb++ ,Fe++ and Cu++ in leaves, while a negative correlation was documented for Cd++ and Zn++. In the bark samples there was a positive correlation between traffic density and Pb++, and a negative one with Cd++, Fe++, Cu++ and Zn ++. A positive correlation was determined between traffic density and the amount of Pb++, Fe++, Cu++ and Zn ++ in soil. However, the amount of Cd++ was 0.2 ppm and no relationship between Cd++ and traffic density was observed. © Triveni Enterprises.
A comparative analysis of medicinal and aromatic plants used in the traditional medicine of Iğdir (Turkey), Nakhchivan (Azerbaijan), and Tabriz (Iran)
(Pakistan Botanical Society, 2018) Ozturk M.; Altundağ E.; Jamshid Ibadullayeva S.; Altay V.; Aslanipour B.
A total of 341 naturally distributed taxa belonging to 65 families are used in the traditional medicine in Iğdır (Turkey), Nakhchivan (Azerbaijan), and Tabriz (Iran). Local people in three different regions generally use herbal remedies for digestive, respiratory, urogenital systems, as well as dermal, neurological and psyschological diseases. On the basis of localities three highly prevelant usesin Iğdır are colds (32 taxa), stomach disorders (28 taxa), and cough (24 taxa); in Nakhchivan rheumatism (24 taxa), gastrointestinal disorders (24 taxa), and anthelmintic (20 taxa), and in Tabriz diuretic (24 taxa), fever (22 taxa), and cough (20 taxa). Our findings reveal that in these three areas belonging to three neighbouring countries 4 taxa are widely distributed and used almost forthe same applications; Glycyrrhiza glabra (for digestive and respiratory systems), Malus sylvestris ssp. orientalis (for respiratory system), Rosa canina (for digestive and urinogenital systems), and Urtica dioica (for digestive system). The studied areas show several resemblances from cultural and other aspects. © 2018, Pakistan Botanical Society. All Rights Reserved.
Compositional changes of major chemical compounds in Greek carob pods during development
(2012) Vekiari A.S.; Ouzounidou G.; Gork G.; Ozturk M.; Asfi M.
Because of the strong association with health benefits of some chemical compounds contained in carob fruit the composition of chemical substances of two common type carob pods (Ceratonia siliqua L.) and their changes during fruit developing in two periods of harvesting were reported. Samples were originated from a site near Rethymno, Crete Island, at an altitude of 100 m above the sea level. The moisture content determined through sample's drying in 70 °C under vacuum, sugars by HPLC (high pressure liquid chromatography), total polyphenols by ultraviolet/visible (UV/Vis) and fatty acids by gas chromatography (GC) in the fleshy and wild types were determined at three stages of development. Principal sugars found were glucose, fructose and sucrose. The predominant fatty acid was linoleic acid (n-6) followed by oleic, palmitic and then linolenic (n-3) fatty acids. The total unsaturated fatty acids content was two times higher than the content of total saturated fatty acids in fully-developed carob pod. The ratio n-6/n-3 was under 5, showing a good equilibrium between the two essential fatty acids. The fully developed fruits of both varieties revealed lower contents of polyphenols, proteins and sugars compared with their previous growth stages. The fleshy carob pods exceed the wild variety in concentration of proteins, sugars and fatty acids, while the wild variety exceeds the fleshy in polyphenols concentration. © 2012 Chemical Society of Ethiopia.
Does neoadjuvant rectal score predict treatment outcomes better than the all grading systems used in neoadjuvantly treated rectal cancer?
(Elsevier (Singapore) Pte Ltd, 2022) Sert F.; Ozturk M.; Yalman D.; Ozkok S.
Background: /Objective: To compare the prognostic value of the yield pathologic (yp) stage, used 4 tumor regression grading (TRG) systems, and neoadjuvant rectal score(NARS) in patients with locally advanced rectal cancer (LARC) who received long-term neoadjuvant chemoradiotherapy (nCRT). Methods: Between 2005 and 2017, we included 302 patients with LARC who treated with nCRT. Postoperative pathological responses were graded by using Dworak, American Joint Committee on Cancer, Mandart, Memorial Sloan Kettering Cancer Center, grading systems and NARS([5ypN-3(kT-pT)+12]2/9,61) calculations. Their results were compared in terms of treatment outcomes. Results: The median follow-up time was 51 months (range 5–136). There was a significant relation between cT stage and the response in used grading systems(p < 0,001). Median overall(OS), local recurrence free(LRFS), and distant metastasis free(MFS) survival rates were 50, 48, and 45 months, respectively. 5-year OS, LRFS, and MFS rates were 71%, 92%, and 72%, respectively. According to the NARS and treatment response grating systems, a significant difference was found between the low risk and high risk groups in terms of OS, LRFS, and MFS rates. While it was not seen any difference in terms of OS and MFS, NARS was found to predict LRFS better than other grading systems. In multivariate analysis, high NARS was found to be correlated with worse OS and worse MFS. On the other hand, pCR was the another important factor affecting treatment outcomes. Conclusions: While used systems except NARS group patients according to ypT status in surgical tissue, NARS add the value of ypN status in addition to ypT status. It could be suggested to use NARS to predict LRFS. © 2022 Asian Surgical Association and Taiwan Robotic Surgery Association
Eco-physiology of capparis spinosa l. : A plant suitable for combating desertification
(2008) Sakcali M.S.; Bahadir H.; Ozturk M.
Capparis spinosa from the family Capparidaceae is widely distributed on varying habitats in Turkey. Recently, it has been recommended for the evaluation of degraded arid lands in the country. This study was thus undertaken to investigate the diurnal time course of water relations of C. spinosa L. growing on healthy and degraded sites. Water stress was analysed on the basis of stomatal conductance (g s), leaf water potential (? w) and transpiration rate. The species appeared to be a drought resistant with lower WSIS (16 MPa h), showing a negligible difference between the two sites. A high g s, with lowest WSIS value shows that despite being a water spender, C. spinosa dynamically recovers even in the warmest hours of the day and under drought conditions. The long roots and wide ecological amplitude allow it to withstand harsh environments. The species thus appears to be a suitable candidate for the protection of degraded areas.
Ecophysiological responses of some maquis (Ceratonia siliqua L., Olea oleaster Hoffm. & Link, Pistacia lentiscus and Quercus coccifera L.) plant species to drought in the east Mediterranean ecosystem
(2010) Ozturk M.; Dogan Y.; Sakcali M.S.; Doulis A.; Karam F.
The objective was to examine the adaptation strategies of four maquis species to drought prone environments; typical of the east Mediterranean area in degraded and healthy sites in Turkey. A comparison made between sites for Pistacia lentiscus and Quercus coccifera shows higher net daily photosynthesis in the degraded site, when compared with the healthy site; but Ceratonia siliqua and Olea oleaster exhibited no difference in their photosynthetic activity in environmentally contrasting conditions. The pattern of daily transpiration shows higher values in the degraded site in the case of P. lentiscus and Q. coccifera, while no site effect was observed for C. siliqua and O. oleaster. In the case of Q. coccifera, a behavior similar to C. siliqua was observed. A comparison made between C. siliqua and O. oleaster to observe seasonal differences in daily patterns of net photosynthesis and transpiration reveals that Q. coccifera had the highest water use efficiency (slope= 2.88; r 2= 0.61), followed by C. siliqua (slope= 2.74; r2= 0.7), P. lentiscus (slope= 2.56; r2= 0.52; and O. oleaster (slope= 2.40; r2 = 0.78). Olea oleaster and P. lentiscus performed as a drought tolerant species, being more resistant to aridity and thus indicative of the degradation state of the site. Ceratonia siliqua and Q. coccifera were found avoiding drought by adopting first a water-spending strategy, and then a water-saving strategy. © Triveni Enterprises.
Effect of survey farmers’ knowledge and practices on the yield of sugarcane in Pakistan
(King Saud University, 2022) Khan F.; Huma Z.; Shah G.A.; Turkyilmaz Unal B.; Ozturk M.
Sugarcane (Saccharum interspecific hybrids) yield is greatly affected by different pests in Pakistan. A total of three hundred and thirty-six (336) volunteer sugarcane farmers were interviewed and their fields inspected. Major pests were noted as; rat (Bandicota bengalensis), termites (Heterotermes indicola), borer (Bissetia steniellus), and leafhopper (Pyrilla perpusilla). These occurred in single and combined status in sugarcane fields. Most (147/336) of the sugarcane farmers mentioned four types of pests in their fields. In general 200/336 of the sugarcane farmers had applied pesticides in single and combined forms in their fields, they achieved a maximum average yield of 80 t ha?1. The number of farmers who applied malathion was 36/336. They achieved an average yield of 105.5 kg ha?1. Only one sugarcane farmer applied regent and furadon in combined form and obtained an average yield of 92.6 kg ha?1 in their field. Linear regression showed a significant relationship between average sugarcane yield and pest infestation (R2 = 0.9689) as well as pesticide application (R2 = 0.9128) in the area investigated. In total 299 out of the 336 sugarcane farmers were small size landholders up to 2 ha. A limited number (35/336) of the farmers visited the public agricultural extension department for information and application techniques of pesticides against pests. It will be fruitful if the public and private agricultural extension departments start awareness programmes on pest infestation among sugarcane farmers and train them to practice recommended pesticide applications in their sugarcane fields. © 2022 The Authors
Elucidating some physiological mechanisms of salt tolerance in Brassica napus L. seedlings induced by seed priming with plant growth regulators
(Pakistan Botanical Society, 2021) Shahrasbi S.; Pirasteh-Anosheh H.; Emam Y.; Ozturk M.; Altay V.
Present study was undertaken to elucidate some physiological mechanisms of induced salt tolerance by different plant growth regulators (PGRs) in rapeseed (Brassica napus L.) seedlings. Three salt stress levels were given; tapwater (0.7 dS m-1), 6 dS m-1 and 12 dS m-1, which made by NaCl and CaCl2 as 2:1 molar ratio. The eight seed priming agents were included: dry seeds (no-priming), hydropriming and six PGRs primings. The used PGRs were; abscisic acid (ABA), auxin (AUX), salicylic acid (SA), chlorocholine chloride (CCC), ascorbic acid (AS) and brassinosteroid (Brs). The results revealed that salinity, depending on level, reduced seedling emergence, shoot and root growth, potassium (K+) concentration and enhanced sodium (Na+) concentration and antioxidant enzymes. These reductions could be attributed to oxidative stress and/or ion balance disturbance due to salinity stress. It is documented by reduced K+ and increased Na+ in both root and shoot as well as enhanced antioxidant enzyme activity and H2O2 in salt stressed rapeseed seedlings. Higher storage factor (SF) refers to a higher ions content kept in roots rather than transporting these to the shoot as salinity level increased. PGRs priming modulates some negative effects of salt stress on emergence, growth and physiological functions of plants. In triggering the ameliorating role of PGRs, it appeared that the ratio of Na+ to K+ is more important than their individual concentrations. Moreover, H2O2 concentration was found to be a better key for estimation of the oxidative damage rather than antioxidative enzymes. Among the PGRs, SA and Brs showed better performance, and it seems that the main mechanism of action for SA was creating ion balance and changing ion partitioning in favor of roots. For Brs it appeared to be reactive oxygen species (ROS) scavenging by inducing higher activity of antioxidant enzymes, particularly catalase. © 2021, Pakistan Botanical Society. All rights reserved.
Enhancing plant productivity under salt stress: Relevance of Poly-omics
(Springer New York, 2013) Hasanuzzaman M.; Nahar K.; Fujita M.; Ahmad P.; Chandna R.; Prasad M.N.V.; Ozturk M.
At present more than 20% of all the irrigated land in the world is estimated as affected by salinity and this trend is increasing with the rapid climate changes as well as the excess use of irrigation water. Salt stress is one of the most devastating abiotic stresses which severely affects the agricultural productivity in various ways. High concentration of salt in the soil or in the irrigation water can have a overwhelming effect on plant metabolism, disrupting cellular homeostasis and uncoupling major physiological and biochemical processes. Salinity cause both osmotic stress and ionic toxicity which hamper the plant productivity by inhibiting or altering the plant growth, dry matter partitioning, seed germination, photosynthesis and yield. Considering the devastating effect of salt stress on plants, one of the important tasks for plant biologists is to explore the approaches that are able to develop salt tolerance in crop plants. In fact, salt tolerance is a multigenic trait which is governed by various morphological and physiological factors. Thus omics approaches therefore, come in forefront to develop salt tolerance as a part of different strategies of conventional plant breeding. Transcriptomics, proteomics, metabolomics, ionomics and micromics together have been a bloom in revealing plant stress responses and the mechanisms that underlie these responses. These techniques have been playing important part in discovering new genes, proteins and secondary plant metabolites those are responsible for plants adaptation to stress. In this review, we have focused on the causes and effects of salinity on crop plants and possible mechanisms of salt tolerance including the possible use of omics in conferring salt tolerance. © 2013 Springer Science+Business Media New York.

The epidemiology and economic impact of varicella-related hospitalizations in Turkey from 2008 to 2010: A nationwide survey during the pre-vaccine era (VARICOMP study)
(2012) Dinleyici E.C.; Kurugol Z.; Turel O.; Hatipoglu N.; Devrim I.; Agin H.; Gunay I.; Yasa O.; Erguven M.; Bayram N.; Kizildemir A.; Alhan E.; Kocabas E.; Tezer H.; Aykan H.H.; Dalgic N.; Kilic B.; Sensoy G.; Belet N.; Kulcu N.U.; Say A.; Tas M.A.; Ciftci E.; Ince E.; Ozdemir H.; Emiroglu M.; Odabas D.; Yargic Z.A.; Nuhoglu C.; Carman K.B.; Celebi S.; Hacimustafaoglu M.; Elevli M.; Ekici Z.; Celik U.; Kondolot M.; Ozturk M.; Tapisiz A.; Ozen M.; Tepeli H.; Parlakay A.; Kara A.; Somer A.; Caliskan B.; Velipasalioglu S.; Oncel S.; Arisoy E.S.; Guler E.; Dalkiran T.; Aygun D.; Akarsu S.
Varicella can cause complications that are potentially serious and require hospitalization. Our current understanding of the causes and incidence of varicella-related hospitalization in Turkey is limited and sufficiently accurate epidemiological and economical information is lacking. The aim of this study was to estimate the annual incidence of varicella-related hospitalizations, describe the complications, and estimate the annual mortality and cost of varicella in children. VARICOMP is a multi-center study that was performed to provide epidemiological and economic data on hospitalization for varicella in children between 0 and 15 years of age from October 2008 to September 2010 in Turkey. According to medical records from 27 health care centers in 14 cities (representing 49.3% of the childhood population in Turkey), 824 children (73% previously healthy) were hospitalized for varicella over the 2-year period. Most cases occurred in the spring and early summer months. Most cases were in children under 5 years of age, and 29.5% were in children under 1 year of age. The estimated incidence of varicella-related hospitalization was 5.29-6.89 per 100,000 in all children between 0-15 years of age in Turkey, 21.7 to 28 per 100,000 children under 1 year of age, 9.8-13.8 per 100,000 children under 5 years of age, 3.96-6.52 per 100,000 children between 5 and 10 years of age and 0.42 to 0.71 per 100,000 children between 10 and 15 years of age. Among the 824 children, 212 (25.7%) were hospitalized because of primary varicella infection. The most common complications in children were secondary bacterial infection (23%), neurological (19.1%), and respiratory (17.5%) complications. Secondary bacterial infections (p<0.001) and neurological complications (p<0.001) were significantly more common in previously healthy children, whereas hematological complications (p<0.001) were more commonly observed in children with underlying conditions. The median length of the hospital stay was 6 days, and it was longer in children with underlying conditions (<0.001). The median cost of hospitalization per patient was $338 and was significantly higher in children with underlying conditions (p<0.001). The estimated direct annual cost (not including the loss of parental work time and school absence) of varicella-related hospitalization in children under the age of 15 years in Turkey was $856,190 to $1,407,006. According to our estimates, 882 to 1,450 children are hospitalized for varicella each year, reflecting a population-wide occurrence of 466-768 varicella cases per 100,000 children. In conclusion, this study confirms that varicella-related hospitalizations are not uncommon in children, and two thirds of these children are otherwise healthy. The annual cost of hospitalization for varicella reflects only a small part of the overall cost of this disease, as only a very few cases require hospital admission. The incidence of this disease was higher in children <1 year of age, and there are no prevention strategies for these children other than population-wide vaccination. Universal vaccination is therefore the only realistic option for the prevention of severe complications and deaths. The surveillance of varicellaassociated complications is essential for monitoring of the impact of varicella immunization. © Springer-Verlag 2011.

Ethnoecology of poisonous plants from West Anatolia in Turkey
(EuroJournals, Inc., 2008) Mert T.; Akcicek E.; Celik S.; Uysal; Ozturk M.
An increase in the use of medicinal plants in Europe has resulted in a parallel development in this direction in Turkey. A large number of flowering plants as well as mushrooms collected with this aim from the wild are sold at the markets or consumed by the public directly after collection. Many times consumption of such plants in particular mushrooms as a whole or parts thereof produce a poisonous effect and even prove fatal. More than 50 poisonous taxa are widely distributed in West Anatolia, 20 of these being mushrooms. This paper enlightens the ethnoecological features of these poisonous taxa. © EuroJournals Publishing, Inc. 2008.
Ethnoecology of poisonous plants of Turkey and northern cyprus
(2008) Ozturk M.; Uysal I.; Gücel S.; Mert T.; Akcicek E.; Celik S.
Interest in plants is increasing and much work is being carried out these days on their multipurpose uses. A great impetus has been given to this during the last 3 decades. Several publications have been made by different investigators. Large number of naturally growing plants are collected and sold at the markets. Nearly 500 plants are used for primary health care in Turkey and a 23 in Cyprus. However, not much is known about the poisonous plants. Some of these are toxic and others cause reaction. Plant poisoning lies around 6 %, rurals suffer more from the consumption of naturally growing plants as compared to urban dwellers. One has to be very cautious before using these plants as the plants used for the purpose of treatment of diseases as a whole or parts thereof or consumed by the public directly could prove dangerous for the health. This paper describes ethnoecological aspects of the widely distributed major poisonous plants in Turkey and Northern Cyprus which can prove fatal if used unknowingly. Major applications and active constituents of plant taxa are outlined.
Ethnopharmacological study of medicinal plants from khoy city of west Azerbaijan-Iran
(National Institute of Science Communication and Information Resources (NISCAIR), 2020) Younessi-Hamzekhanlu M.; Ozturk M.; Altay V.; Nojadeh M.S.; Alakbarli F.
The main objective of this study was to gather information on the use of plants by native people along with therapies suggested by the conventional healers of Khoy. It was analyzed and some important indices including, frequency of citation (FC), cultural importance index (IC), use report (UR) and informants consensus factor (ICF) were calculated.
