Doğada elemental olarak bulunmayan bor, yerkabuğunda yaygın bulunur ve periyodik tablonun 5.elementidir. Yaklaşık 230 farklı bor mineralinin bulunduğu bilinmektedir uygulamalarda bu çeşitlilik önemlidir. Türkiye, dünyadaki rezervlerinin en büyüğüne sahiptir. Buna ek olarak, Türkiye'nin mineralleri, diğer üreten ülkelere göre daha ekonomik olan yüksek kalite üretim koşullarına Bu nedenle, ülkemi...
In order to understand the causes of the emission shape and colour changes of heteroleptic Ir3+ complexes containing 2-(2,4-difluorophenyl)pyridine (dfppy) as the main ligands, we introduced two types of ancillary ligands: (1) non-luminescent ancillary ligands, namely tetrakis(pyrazolyl)borate (bor) and picolinate (pic), which were employed for the preparation of Ir(dfppy)2(bor) and Ir(dfppy)2(...
Bor, hayvan ve insan biyolojisi için çok önemli olan dinamik bir eser elementtir. Bor sitrat, borun metabolizmaya alımındaki en yaygın formlardan biridir. Bu çalışmada oral olarak bor sitrat uygulanan ratların hem plazmalarında de serumlarında ICP-MS yöntemi ile miktarı tayin edilmiş 20 mg/kg ratlardan farklı zamanlarda alınan serum plazma numunelerindeki konsantrasyonları edilerek zamana göre ...
The purpose of this study was to evaluate 18F-FDG PET/CT scanning as an early predictor of response to immune checkpoint inhibitors (ICIs) in patients with advanced melanoma. Methods: Twenty patients with advanced melanoma receiving ICI prospectively underwent 18F-FDG PET/CT at 3 scan intervals: before treatment initiation (SCAN-1), at days 21-28 (SCAN-2), and at 4 mo (SCAN-3). This study was a...
The prokaryotic diversity in the Bor Khlueng hot spring in Ratchaburi province, Thailand was investigated by a culture-independent molecular approach. This hydrothermal pool is located in the central part of Thailand and contains sulfide-rich mineral water that is believed to relieve muscle ache and pain. The water flow year-round with temperature ranging between 50-57 degrees C. Community DNA ...
Ipilimumab (IPI) blocks CTLA-4 immune checkpoint resulting in T cell activation and enhanced antitumor immunity. IPI improves overall survival (OS) in 22% of patients with metastatic melanoma (MM). We investigated the association of CTLA-4 single nucleotide variants (SNVs) with best overall response (BOR) to IPI and OS in a cohort of 173 MM patients. Patients were genotyped for six CTLA-4 SNVs ...
Three-dimensional (3D) covalent organic frameworks (COFs) possess great potential applications in various fields. Constructing 3D COFs with large pore sizes is extremely challenging due to the interpenetration and collapse. Herein, we report a series of crystalline imine-linked (3D-bor-COF-1, 3D-bor-COF-2, 3D-bor-COF-3) mesoporous channels through rationally designing topology configuration. Th...
