A Scorpion Compsobuthus schmiedeknechti (Scorpions: Buthidae) New to The Turkish Fauna
Ismail Varol,Ersen Aydin Yagmur,Mehmet Ozaslan,Mehmet Yalcin
Pakistan Journal of Biological Sciences , 2006,
Abstract: This is the first study of the buthid scorpion Compsobuthus schmiedeknechti Vachon, 1947 from Turkey. Female scorpion specimens were collected from the eastern Mediterranean region of Turkey (Yayladag-Hatay). Morphological structures, taxonomic features and illustrations were used to determine that the specimens were Compsobuthus schmiedeknechti. This species is a new record for Turkish scorpion fauna.
The Phenological Records on Eresus Cinnabarinus (Olivier, 1789) (Araneae: Eresidae)
Selda Kesmezoglu,Ismail Varol,Ersen Aydin Yagmur,Murat Kutuk
Journal of Biological Sciences , 2006,
Abstract: In this study, maturing periods, hatching and bringing out eggs of Eresus cinnabarinus investigated. Eresus cinnabarinus is one of member of the palearctic that poisonous for people compared with the others. The laboratory investigations showed that the period of ovulation and hatching out of coccon was at the middle of June and August, respectively. Sub-adult individuals were lived two months and become adult after 16-18 months. In the observation, 382 individuals hatched out of the coccon and fed by Drosophila sp.
Investigation on Spider Fauna of Hancagiz Dam-Nizip (Turkey)
M. Ismail Varol,Cafer Mart,Mehmet Ozaslan,Abdullah Bayram
Journal of Biological Sciences , 2006,
Abstract: In this study, spider fauna of Hanca iz Dam (Gaziantep) was studied. In field trips, 817 specimens were collected; male and female examples were identified. As a result of determination, 18 families were recognized. Philodromidae, Lycosidae, Gnaphosidae and Thomisidae families were studied as detailed. Eight genus and 17 species were given as systematic categories.
The Spider Aulonia kratochvili (Araneae: Lycosidae) New to the Turkish Fauna
Ismail Varol,Zubeyde Akan,Adile Ozdemir,Faruk Kutbay
Journal of Biological Sciences , 2007,
Abstract: The spider Aulonia kratochvili (Dunin, Buchar, Absolon, 1986) is newly recorded for Turkey. The characteristic features, distribution, ecology, genital structure is described. The specimens were collected from North-East and South-Eastern parts of Turkey.
Fluorosis as an Environmental Disease and its Effect on Human Health
Ercan Varol,Simge Varol
TAF Preventive Medicine Bulletin , 2010,
Abstract: Fluoride is a halogene found in earth, water, rocks, air, plants and animal tissue in various amounts. In normal conditions, people daily take fluoride compounds in amounts without any harmful effects this cause fewer dental caries and the formation of stronger bones. However, if the amount of fluoride taken daily exceeds the safety threshold, chronic fluoride intoxication, known as fluorosis, arises. As a result of fluorosis, pathological changes appear in tooths, skeletal system, liver, kidney, heart, gastrointestinal system and endocrin system. [TAF Prev Med Bull 2010; 9(3): 233-238]

Classification of Heavily Damaged Building Damage after Earthquake
Varol Ko?
Dogal Afetler ve Cevre Dergisi , 2016, DOI: 10.21324/dacd.25533
Abstract: In this study, severe damage types in concrete buildings observed after earthquakes were classified and investigated in relation to the structural behaviors. Since the damage types are very extensive, particularly heavy damages caused by column and combination of beam-column damages were discussed. Classification is made primarily in the form of damage types of the structural system and damages of structural elements. Classification of damage types of structural system was grouped as 1) Overlap collapse related damages, 2) Lateral collapse (accordion) damages, 3) Tilting damages, 4) Failure of a part on vertical alignment type damages, 5) Failure of a part of horizontal alignment type damages and 6) Horizontal failure of entire story while the damages of structural elements were grouped as 1) Out of plane deboning of column and 2) End part damages of column. Beams and floor damages, also considered as structural system damages, are not included in the scope of this study. This study summarizes precautions needed to be taken to prevent such damages studied.
The Relationship between p53 Expression and Human Papillomavirus in Premalignant and Malignant Uterine Cervical Lesions  [PDF]
Beyhan Varol Mollamehmetoglu, Havva Erdem, Muzaffer Keles
Open Journal of Pathology (OJPathology) , 2016, DOI: 10.4236/ojpathology.2016.62009
Abstract: Objective: We aimed to retrospectively examine a series of premalignant and malignant cervical tissues to study a high-risk HPV 16 infection that, among cervical tissue lesions, carries the greatest risk of conversion to cancer, and the presence of p53 protein immunoreactivity, a tumor suppressor gene product. Methods: Paraffin blocks were studied via immunohistochemical (IHC) method to explore the presence of HPV 16 in 59 premalignant and malignant cervical lesions as well as immunoreactivity of the p53 oncoprotein, the most common cellular tumor suppressor gene product in human cancers. Results: In our series, mutant p53 positivity rate was 35.3% for low-grade CIL, 40% for high-grade CIL, and 46.8% for invasive carcinoma cases. Immune staining for high-risk HPV 16 type yielded a positive staining rate of 47% in low-grade CIL, 80% in high-grade CIL, and 50% in invasive carcinoma. Conclusion: The results of our study indicate a progressive increase in p53 oncoprotein reactivity from cervical intraepithelial neoplasia to invasive carcinoma. This suggests the clinical importance of p53 immunoreactivity in dysplastic progression and neoplastic transformation. HPV is the most commonly encountered oncogenic type in cervical lesions, especially in high-grade CIL and invasive carcinomas. Results of the previous reports suggest that HPV-positive carcinomas release wild type p53 and HPV-negative ones release mutant type p53 were not confirmed by our results, which indicated a mutant type p53 reactivity in HPV- 16 positive carcinoma cases.
Groundwater Chemistry and Assessment of Its Effect on Health from the Aspect of Medical Geology
Simge Varol,Aysen Davraz,Ercan Varol
TAF Preventive Medicine Bulletin , 2008,
Abstract: Geology and medicine are the oldest two sciences. Nowadays, medical geology is appeared to associate the researches related to environmental problems studied by geology and medical sciences. In the medical geology, researches related to effect of groundwater on human health is the most important subject. In this paper, elements which are the constituent of groundwater and health problems originated from those elements were explained. In addition, components polluting the groundwater widely were presented in detail. [TAF Prev Med Bull. 2008; 7(4): 351-356]
