Progranulin (PGRN) is a multifunctional protein that is critical in the retention of embryos in the endometrium of the uterus and the protection of cervical tissue during fetal growth. In case of PGRN release and dysfunction, cervical tissue may remodel (regeneration) and lead to the risk of abortion. Serum PGRN level in sheep and its variation according to different physiological periods and its relationship with some biochemical parameters are unknown. In this study, the relationship between early lactation, early and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep was investigated for the first time. In the literature search, no similar studies were found on the relationship between early lactation, earl y and late pregnancy serum PGRN levels and some biochemical parameters in Akkaraman sheep. The research was carried out on 90 Akkaraman sheep reared in the same herd under the same care and feeding conditions. In the study, Akkaraman ewe were divided into 3 groups as early lactation, early pregnancy and late pregnancy. 1st group is early lactation period ewe (first 60 days of lactation), (n = 30), 2nd group is in the first period of pregnancy (on the 0–90th day of the first pregnancy (n = 30)), 3rd group is in the late pregnancy of pregnancy (100–150 days of pregnancy (n = 30)) was created. Blood samples from vena jugularis were taken before morning feeding from the animals that formed the study groups. PGRN levels in serum were determined by ELISA method. In addition, glucose, calcium (Ca), magnesium (Mg), phosphorus (P), total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL), high density lipoprotein (HDL), very low density lipoprotein (VLDL) levels were analyzed in biochemistry autoanalyzer. As a result of the study, lactation and early pregnancy and late pregnancy mean serum PGRN levels were determined as 1.93, 1.78, 1.33 ng mL-1, respectively. The serum PGRN, glucose, Ca, Mg, P, TC, TG, LDL, HDL and VLDL levels of sheep with late pregnancy, early lactation and early pregnancy periods, which constitute the study groups, were found to be statistically significant (P<0.05). Our results have shown that due to the physiological role of PRGN in keeping the embryo in the endometrium of the uterine and in preserving the cervical tissue during fetal growth, there may be a useful parameter in the pursuit of the pregnancy process. © 2023, University of Agriculture.

ANOTHER APPLICATION OF SMARANDACHE BASED RULED SURFACES WITH THE DARBOUX VECTOR ACCORDING TO FRENET FRAME IN E3
Senyurt, Suleyman; Canli, Davut; Can, Elif; Mazlum, Sumeyye Gur
In this study, we first define the Smarandache curves derived from the Frenet vectors and the Darboux vector of any curve. Then, we construct new ruled surfaces along these Smarandache curves with the direction vec-tors obtained from the Frenet vectors and the Darboux vector, and give the equations of these surfaces. In addition, we calculate the Gaussian and mean curvatures of these surfaces separately and present the conditions to be min-imal and developable for these surfaces. Finally, as an example, we obtain ruled surfaces whose base curves are Viviani's curves and plot the graphics of these surfaces.

In this paper, we calculate Frenet frames, Frenet derivative formulas, curvatures, arc lengths, geodesic curvatures according to the Lorentzian 3-space R31, Lorentzian sphere S21 and hyperbolic sphere H2 0 of the spherical indicatrix curves of the spacelike Salkowski curve with the timelike principal normal in R3 1 and draw the graphs of these indicatrix curves on the spheres.

Some properties of fuzzy sedenion numbers and fuzzy sedenion valued series
Bektas, Ozcan; Senyurt, Suleyman; Mazlum, Sumeyye Gur
The analytic properties of fuzzy sedenion numbers and sedenion valued series are studied. For this aim, we first introduce fuzzy sedenion numbers. Then we present infimum, supremum, distance, limit of sequences and other analytical properties of fuzzy sedenion numbers. We also define interval sedenion numbers and fuzzy sedenion valued series. Finally, we obtain comparison criteria of the fuzzy sedenion valued series. © 2023 by Maejo University, San Sai, Chiang Mai, 50290 Thailand. Reproduction is permitted for noncommercial purposes.
