Comparing Botanical Origin and Volatile Compounds of Some Turkish Honey Samples

The aim of this study is to determine relations exist between microscopic analysis and chemical profile in ho- ney samples collected from Turkey. For this purpose, nine honey samples were collected. Eight of them were obtained from different locations of Turkey (Adana, Erzincan, Erzurum, Düzce, Rize, Hatay) and one from market shelf. The samples were grouped according to their botanical origins after microscopic analysis. According to the results of microscopic analysis, we found that four of them are multifloral, three of them are chesnut, one of them is Calluna and the last one is honeydew honey. The volatile compounds of the honey samples were determined by Solid Phase Microextraction/Gas Chromatography and Mass Spectrometry (SPME/GC-MS) method. The results showed that it is impossible to standardize the multifloral honeys in chemical composition base. Accor- ding to our results “Aminoacetophenone” can be a marker compound for chesnut honeys, “Nonanal” for Calluna honey. Definite marker compound could’nt be identified for investigated honeydewhoney in this research.

Claw Wing: Unnoticed Character in Floral Morphology of The Genus Dianthus (Caryophyllaceae) with Taxonomic Implication and a New Section

The specimens of Dianthus pinifolius Sm. were collected during a field trip to the Bulgarian border of NW Tur- key. It was recognized that the petals have a pair of wing on claw and it has a billamellate shape. Hairs, colour zonation of the limb, and ridges on the claws have been long known as typical petal characters of Dianthus. In this study claw wing is recognized in this species of the genus for the first time and reported to the scientific community. Generic circumscription of Dianthus L. is enlarged by recognition of the claw wing by comparing with the other genera of the Caryophyllaceae. Furthermore, in consideration of the diagnostic characters for delimiting the infrageneric taxa, the presence of claw wing is justified as a diagnostic character for describing a new section of Dianthus, hence Sect. Pinifoli Dönmez sect. nov. proposed as a new section for the genus. Diagnostic characters of the section, description, detailed illustration and a composed picture of the type spe- cies are also supplied.

Surface Modifications of Cationic Polyamidoamine (PAMAM) Dendrimers

PAMAM dendrimers are a new class of macromolecular polymers, with a highly branched three-dimensional structure that provides a high degree of surface functionality and versatility. These nanospherical polymers possess exclusive properties which make them potential carriers for drug and gene delivery. PAMAM dendrimers allow the precise control of size, shape and placement of functional groups that is desirable for many life science applications. However, positive charge at the surface renders cytotoxicity to the cationic PAMAM dendrimers, which limits their clinical usefulness. Modification of dendrimer surface groups is one of the methods available in order to reduce the toxicity and improve their biocompatibility. In this review, firstly a brief description is provided about the characteristics and structure of PAMAM dendrimers. Then, various modification routes with the aim of decreasing the cytotoxicity of PAMAM dendrimers are presented and discussed.

The impacts of some metals on the activity of corb gill (Umbrina cirrosa) Carbonic Anhydrase

Metal toxicity causes oxidative stress in fish. This situation is a potential risk factor for humans and other living feeding on contaminated fish. In this study, the inhibition effects of heavy metals on carbonic anhy- drase enzyme from the corb fish gill were investigated. The carbonic anhydrase enzyme was purified from gill of corb fish with a specific activity of 2093,9 EUmg−1 and 86,51% yield and approximately 160 fold using Sep- harose 4B–L-tyrosine sulfanilamide affinity chromatography method. SDS–polyacrylamide gel electrophoresis showed a single band corresponding to a molecular weight of approximately 30,8 kDa. Inhibitory effects of metals (Ag+, Cu2+, Pb2+, Zn2+, Cd2+, Ni2+) on CA activity were determined at different concentrations using the hydratase method under in vitro conditions. Consequently, in vitro inhibition rank order was determined as Ag+> Cu2+> Pb2+> Zn2+ > Cd2+> Ni2+. From these results, we showed that Ag+ is the most potent inhibitor of CA enzyme.

Human IgG Adsorption by Spherical Albumin Biosorbents in SBF Media

The objective of this study was to investigate the removal efficiency of immunoglobulin G (IgG) by albumin bi- osorbents in batch wise in four different simulated body fluid (SBF) solutions at room temperature. Albumin biosorbents were prepared as microsphere form by emulsion polymerization method. 0.1 g/ml albumin concentration, 1000 rpm stirring rate, 1% glutaraldehyde (GA) concentration 30 minutes crosslinking time were determined as optimal conditions in our previous study. The prepared biosorbents were then studied for IgG removal efficiency in four simulated body fluid (SBF) solutions [N(Normal)-SBF, G(glucose)-SBF, H(hepes)-SBF, T(tris)-SBF] at room temperature. IgG capturing capacity was obtained as 320 mg IgG/g with albümin biosor- bent (94,6%) in N-SBF. It was observed that there was no leakage at washing with water. It may be concluded that prepared albumin biosorbents are sufficient in terms of efficiency of IgG removal. It was seem that this method is easy to perform and is useful as a first step in the detection of diagnostic markers in body fluids by applying proteomics technologies. We believe that albumin biosorbents offered the promising approach with good removal specificity and efficiency of IgG.

Temperature Profiles And Sex Ratio Estimation For Green Turtle (Chelonia mydas) Hatchlings On Sugözü Beaches

In this study, the effect of nest temperature and surrounding sand temperature on sexual differentiation were examined for green turtle (Chelonia mydas) hatchlings on Sugözü Beaches (Adana, Turkey) in 2005 nesting season. Nest temperatures were found to be higher than the surrounding sand temperatures, especially du- ring the middle and last third period of incubation (respectively, 0.6°C and 1.9°C). The nest temperature was mostly related to the incubation duration and this was followed by the distance of the nest from the sea and the clutch size. Any relationship between nest temperature and nest depth was not found. Nest temperatures (ranged between 29.4-31.6°C) and middle third temperatures (ranged between 29.5-31.3°C) were measured above 28.9°C, which is the pivotal temperature. The sex ratio in green turtle hatchlings in the area investigated according to the temperature profile was prominently biased toward females.

Silica Based Specific Adsorbents for DNA Purification

The aim of this study is to prepare silica based affinity sorbents for the purification of plasmid DNA and ge- nomic DNA. For this purpose, (3-aminopropyl)trimethoxysilane (APTS) is chosen for surface modification of silica particles (average size: 100-150 μm) and silica based affinity sorbent carrying NH2 groups on its surface is obtained. APTS modified and unmodified silica particles are characterized by elemental analysis. Adsorption of genomic DNA on the APTS modified silica particles is performed in continuous and batch systems. Effect of io- nic strength, pH, temperature, initial genomic DNA concentration and flow rate is investigated. In the last part of the study, pEGFP-N3 plasmid DNA is separated from E.coli cells by using the APTS modified silica particles and the results are compared with commercial Qiagen DNA purification kit. The results may be summarized as follows: amount of NH2 groups on the APTS modified silica particles is in the range of 38-60 mmol/g. Maximum adsorption capacity of the APTS modified silica particles is found to be 49.3 mg/g and this value is obtained at pH 7.0. Genomic DNA adsorption capacity of the APTS modified silica particles is increased in continuous system. It is also shown that the APTS modified silica particles can be used after ten adsorption-desorption cycle without any significant decrease in adsorption capacity. The APTS modified silica particles are used for adsorption of plasmid DNA from E.coli cells and adsorption capacity is found to be 0.21 mg/g in continuous system.
