Age, Gender, Biometry, Refractive Error, And The Anterior Chamber Angle Among Alaskan Eskimos, Robert Wojciechowski, Nathan Congdon, William Anninger, Aimee Teo Broman
Age, Gender, Biometry, Refractive Error, And The Anterior Chamber Angle Among Alaskan Eskimos, Robert Wojciechowski, Nathan Congdon, William Anninger, Aimee Teo Broman
Dartmouth Scholarship
The prevalence of angle-closure glaucoma (ACG) is greater for Eskimos/Inuit than it is for any other ethnic group in the world. Although it has been suggested that this prevalence may be due to a population tendency toward shallower anterior chamber angles, available evidence for other populations such as Chinese with high rates of ACG has not consistently demonstrated such a tendency.
Revised Age For Mojokerto 1, An Early Homo Erectus Cranium From East Java, Indonesia, Michael Morwood, P O'Sullivan, E E. Susanto, F Aziz
Revised Age For Mojokerto 1, An Early Homo Erectus Cranium From East Java, Indonesia, Michael Morwood, P O'Sullivan, E E. Susanto, F Aziz
Faculty of Science, Medicine and Health - Papers: part A
Dates of around 1.8 Ma have been claimed for a hominin cranial vault excavated near Mojokerto City in East Java, Indonesia. Such an early date for presumed Homo erectus in East Asia would require a major revision of the general model for timing of initial hominin dispersal 'Out of Africa'. Instead, our field study and redating of two pumice horizons at the site indicate that the age of the Mojokerto cranial vault is less than 1.49 Ma. Furthermore, we argue that a basic understanding of site and regional depositional processes is fundamental for assessing the significance of any radiometric date.

The Effect Of Age, Sex, Housing System And Pregnancy On Some Blood Parameters Of Tuj Sheep, Ömer Bozdoğan, Meti̇n Çenesi̇z, Mehmet Kaya, Nadi̇de Nabi̇l Kami̇loğlu
Turkish Journal of Veterinary & Animal Sciences
In this study some blood parameters and the effects of age, sex, housing system and pregnancy of Tuj sheep that have been bred in the Kars region of Turkey were researched and compared. The various blood parameters including the amount of haemoglobin, haematocrit value, erythrocyte and leukocyte count, and the differential percentage of white blood cells were determined from blood taken intravenously. The haemoglobin and erythrocyte values were found to be significantly (p < 0.05) higher in 5-7-month-old Tuj sheep grazing in an open field than in 2-3-month-old male Tuj sheep feeding in a closed system. The erythrocyte count was found to be higher in 2-3-month-old female Tuj sheep in comparison to males. The haemoglobin, leukocyte and haematocrit values were also higher in this group of animals, though this was not statistically significant. The erythrocyte, leukocyte, haemoglobin, haematocrit values and differential percentage of white blood cells were not different in 5-7-month-old male and female Tuj sheep grazing in an open area. The erythrocyte number decreased after parturition in respect to the oestrus and pregnancy period. This decrease was statistically significant. The erythrocyte values were 10.2 x 10^6 /mm^3 before oestrus, 9.5 x 10^6 /mm3 during pregnancy and 8.2 x 10^6 /mm^3 after parturition. The haemoglobin value decreased significantly (p < 0.05) during pregnancy. The leukocyte number was found to be less during pregnancy in comparison to other periods; it was 7.7 ± 1.9 x 10^3 /mm^3 during pregnancy, 9.3 ± 1.9 x 10^3 /mm^3 before oestrus, and 9.7 ± 2.5 x 10^3 /mm^3 after parturation. The lymphocyte percentage increased significantly (p < 0.05) during the pregnancy period.

Effect Of Some Environmental Factors On Milk Yield Traits In A Brown Swiss Herd Reared At The Bahri Dağdaş International Agricultural Research Institute, Muammer Ti̇lki̇, Şeref İnal, Mehmet Çolak, M. Emi̇n Teki̇n
Turkish Journal of Veterinary & Animal Sciences
This study was carried out to investigate milk yield traits and some environmental factors affecting milk yield traits in Brown Swiss cattle reared at the Bahri Dağdaş International Agricultural Research Institute. Between 1987 and 1998, 730 lactation records obtained from 273 cows were evaluated. The least-squares means of measured milk yield, 305-day milk yield, dry period and lactation duration were 3631 kg, 3332 kg, 97.1 days and 313.8 days, respectively. Both year and age statistically affected (P < 0.01-0.001) milk yield and lactation duration, but the calving season was not affected (P > 0.05). The effect of the year on dry period was also significant (P < 0.01), but the effect of age and calving season were not significant (P > 0.05).

Turkish Journal of Veterinary & Animal Sciences
The aim of this research was to establish whether the dietary preferences of perch (Perca fluviatilis L., 1758) change due to age and the seasons. Food items were examined by the Geometric Index of Importance (GII) method. The results obtained from this index were also evaluated in relation to seasonal and age-dependent variables. It was observed that the dietary preferences of perch do not change with age and the seasons.

Hepatitis E virus (HEV) causes epidemics in developing countries such as India, Burma, Indonesia, Chad and China, but it causes sporadic cases in developed countries such as the U.S.A., Canada and the U.K. Turkey represents a bridge between HEV endemic and non-endemic areas, and HEV may cause epidemics in Turkey. In this study, the prevalence of HEV in three distinct regions of Turkey and its relationship with age, gender, education and abortions was investigated. Nine hundred ten randomly selected cases from three cities in three geographic regions of Turkey (Manisa from the Aegean region, Elmadağ/Ankara from Central Anatolia and Diyarbakır …
