xTriticosecale Witm, seed size, drought, germination, seedling growth.
Effect of seed size (small, medium and large) on germination and seedling growth of triticale (xTriticosecale Witm. cv. Presto) at the different osmotic potential of NaCl and PEG solutions weredetermined in the present study. Germination tests were conducted under five osmotic potential levels (-0.45, -0.77, -1.03, -1.44 MPa, and Control) of PEG 6000 and NaCl. Germination percentage (%) at 4 and 8th days and also seedling growth traits such as root and shoot length (mm), dry root and shoot weight (mg), root : shoot length (R:S) ratio, and relative water content of shoot (RWC, %) were investigated inthis study. The results indicated that decreases in the osmotic potentials caused a reduction in germination percentage and seedling growth. It was seen that drought created by PEG 6000 had morenegative effects on germination and seedling growth than that of NaCl. In consequence, the total germinability and seedling growth were higher in large seeds rather than in small seeds in control solution and under osmotic stress. In addition, it was observed that seedlings obtained from larger seeds survived even at the lower osmotic potential of PEG and NaCl; whereas, seedling obtained from small seeds did not survive in the intensive stress

Investigation of anxiety, depression and quality of life levels in migraine patients seeking surgical treatment
Objective: Pharmacotherapeutics have been used as a
primary agent in migraine treatment. The detection of
triggers that exacerbated migraine in recent years and
the effectiveness of the surgical interventions applied in
this area have been demonstrated. The aim of this study
was to investigate the depression, anxiety and quality of
life in migraine patients seeking surgical treatment by
comparing them with migraine and non-migraine group.
Method: A total of 105 participants were included in the
study: 35 migraine patients seeking surgical treatment,
35 migraine patients not-seeking surgical treatment, and
35 healthy controls without migraine. Participants filled
out forms consisting of Beck Depression Scale, Beck
Anxiety Scale, SF-36 Quality of Life Scale and sociodemographic data form. One-way analysis of variance and
Post-hoc Bonferroni test were used to assess intergroup
depression, anxiety and quality of life scores.
Results:Anxiety (F=6,02; p=0,003), and depression
(F=10,72; p<0,001) scores were higher in migraine
patients seeking surgical treatment group. In the quality
of life subscales, bodily pain scores were higher
(F=13,09; p<0,001); role-physical (F=14,72; p=0,003)
and role-emotional (F=6,11; p=0,003) scores were
found to be lower than the other groups. Discussion:
Surgical treatment seeking behavior in migraine patients
is associated with more severe anxiety and depression
and worse quality of life. Psychiatric evaluation of
migraine patients seeking surgical treatment may be
important in detecting psychiatric disorders at the diagnostic level and in increasing the quality of life of
patients
ANALYZING THE RETRIEVAL ACCURACY OF OPTICALLY ACTIVE WATER COMPONENTS FROM SATELLITE DATA UNDER VARYING IMAGE RESOLUTIONS
Water quality monitoring has a key role in maintaining a sustainable ecosystem and environmental health. To ensure consistent monitoring, remote sensing provides regular data acquisition with varying spatial resolutions. However, more accurate, and effective solutions can be achieved by integrating remote sensing data with in-situ measurements. This study investigates the integration of in-situ measurements with satellite data, which have different spectral and spatial resolutions, using linear and exponential regression models for four optically active components in the Gulf of Izmit. In this context, Sentinel-2 (S2) and PlanetScope SuperDove (PS) multispectral images, which were acquired on the same date, were used for the comparative analysis of the accurate mapping of chlorophyll-a (Chl-a), turbidity, Secchi disk depth (SDD) and total suspended matter (TSM) water quality parameters combined with simultaneously collected in-situ measurements. The models were evaluated using validation data, along with visual comparison, to assess their accuracy. The results indicate that, overall, exponential models provide more accurate results than linear models, except for the SDD parameter. Furthermore, models created with S2 data demonstrate better performance in retrieving water quality parameters for Chl-a, turbidity, and TSM, with R2 values of 0.71, 0.84, and 0.91, respectively. The linear model created with PS data stands out in the accurately mapping of SDD parameter. Nevertheless, the spatial distribution of these parameters using both satellite dataset exhibits a similar pattern throughout the gulf, which is under threat from significant terrestrial pollution sources, particularly in the eastern part
