BACKGROUND: Oxidative stress contributes to both intraocular pressure regulation and glaucomatous neuropathy. The systemic redox status (solitary determination) was examined in primary open-angle glaucoma (POAG) patients with cataract and nonglaucomatous cataract patients. Cataract-matched group comparisons appear more precise in the context of oxidative stress evaluation. The aim of this study was to establish if systemic oxidative status in POAG patients was elevated compared with the cataract only subjects...

BACKGROUND: Behçet's disease is a vasculitis, seen more frequently around the Mediterranean and the Far East, and evinces with oral and genital ulcerations, skin lesions and uveitis. Carbonic anhydrase (CA) is a metalloenzyme which is widely distributed in the living world, and it is essential for the regulation of acid-base balance. Anti-CA antibodies have been reported in many disorders, such as systemic lupus erythematosus, Sjögren's syndrome, rheumatoid arthritis, endometriosis, idiopathic chronic pancreatitis, type 1 diabetes and Graves' disease...

Preimplantation genetic diagnosis involves the diagnosis of a genetic disorder in embryos obtained through in vitro fertilization, selection of healthy embryos, and transferring them to the mother's uterus. Preimplantation genetic diagnosis has been used not only to avoid the risk of having an affected child, but also by using HLA matching together, it offers preselection of potential HLA-genoidentical healthy donor progeny for an affected sibling, who requires bone marrow transplantation. Here, we share the hematopoietic stem cell transplantation results of 52 patients with different benign and malign hematological or metabolic diseases or immunodeficiencies, whose donors were their siblings borned with this technique in Turkey since 2008...

Regenerative repair of the vascular system is challenging from the perspectives of translational medicine and tissue engineering. There are fundamental hurdles in front of creating bioartificial arteries, which involve recaputilation of the three-layered structure under laboratory settings. Obtaining and maintaining smooth muscle characteristics is an important limitation, as the transdifferentiated cells fail to display mature phenotype. This study aims to shed light on the smooth muscle differentiation of human adipose stem cells (hASCs)...

Tail gut cysts are rare congenital lesions developing from postanal primitive gut remnants. They are mostly benign but carry a potential of malignant transformation, such as adenocarcinoma, neuroendocrine tumor, adenosquamous carcinoma, and pseudomyxoma peritonei. We present a 39-year-old woman with a neuroendocrine tumor arising within a tail gut cyst. She underwent complete resection in 2011. After 4 years, she was admitted with breast nodules, left proptosis, and gaze difficulties. Ga-DOTATATE PET/CT demonstrated extensive metastases including pelvic, lymph node, adrenal gland, bone, retro-orbital, cardiac, breast, skin, and subcutaneous metastases...

Transforming growth factor β1 (TGFβ1) is a well-established inducer of the epithelial-mesenchymal transition (EMT) that is essential for the acquisition of malignant properties, such as invasion, in tumor cells. Although recent studies suggest that the EMT in tumor cells is associated with reprogramming of energy metabolism and TGFβ1 has been shown to stimulate glycolysis in multiple primary cell lines, little is known about TGFβ1's effect on glycolysis and glycolytic regulators in transformed cells. Given the known regulatory role of 6-phosphofructo-2-kinase/fructose 2,6-bisphosphatase-3 (PFKFB3) in glycolysis and association of glycolytic activity with malignant features such as invasion, we sought to investigate whether TGFβ1 regulates PFKFB3 expression and if PFKFB3 is involved in the TGFβ1-mediated increase in the invasive ability of the Panc1 cell cline-a well-established model of TGFβ1-initiated EMT...

Schwannomas are benign, slow growing, encapsulated tumours that originate from the Schwann cells. Intraoral schwannomas are rare, and most of these tumours involve the tongue. They are rarely located in the hard palate or in the facial soft tissue. Herein, we present the clinical and histological features as well as the prognoses of two male patients with schwannoma, one of which was localized to the hard palate and the other to the facial soft tissue around the mandibular mentum and caused swelling.

Nasal turbinates are embryologically derived from a series of outgrowths from the foetal lateral nasal wall. These outgrowths form a series of ridges, referred to as "ethmoturbinals" and have several vital functions. Several different turbinate variations have been reported so far. The authors presented 3 patients of coronal clefted concha who were diagnosed with magnetic resonance imaging. Computed tomography scans and nasal endoscopic examinations are also performed subsequently. These patients are the first coronal clefted concha cases in the literature and also the first radiological study defining concha cleft...

BACKGROUND: This paper uses simulation to explore how gene drives can increase genetic gain in livestock breeding programs. Gene drives are naturally occurring phenomena that cause a mutation on one chromosome to copy itself onto its homologous chromosome. METHODS: We simulated nine different breeding and editing scenarios with a common overall structure. Each scenario began with 21 generations of selection, followed by 20 generations of selection based on true breeding values where the breeder used selection alone, selection in combination with genome editing, or selection with genome editing and gene drives...

Symbiotic bacteria assist in maintaining homeostasis of the animal immune system. However, the molecular mechanisms that underlie symbiont-mediated host immunity are largely unknown. Tsetse flies (Glossina spp.) house maternally transmitted symbionts that regulate the development and function of their host's immune system. Herein we demonstrate that the obligate mutualist, Wigglesworthia, up-regulates expression of odorant binding protein six in the gut of intrauterine tsetse larvae. This process is necessary and sufficient to induce systemic expression of the hematopoietic RUNX transcription factor lozenge and the subsequent production of crystal cells, which actuate the melanotic immune response in adult tsetse...

In this study, we synthesized poly(N-vinylcaprolactam)-g-collagen (PNVCL-g-Col) by grafting collagen with carboxyl group-terminated thermosensitive PNVCL-COOH. The resulting biopolymer was evaluated for its structural, thermal, and rheological properties. Aqueous solutions of PNVCL-g-Col exhibited a temperature-dependent phase transition around human physiological temperature (at ∼38.5 °C), and temperature-dependent tunability. PNVCL-g-Col exhibited temperature-dependent release of the model drugs, lidocaine hydrochloride and bovine serum albumin...
