While the use of genomic data has the potential to revolutionize patient care, there is still much work to be done with regard to the transformation of host-tumor interactions into favorable clinical outcomes for our patients. High-throughput technologies, such as next-generation sequencing (NGS), have rapidly advanced our understanding of oncology, and we are learning that most tumors do not simply possess consistently mutated genes that are responsible for tumorigenesis, facilitating the need for personalized cancer therapy...

We investigated the effects of γ-radiation on the survival of resting eggs of the cladoceran Moina macrocopa, on the parameters of the life cycle of neonates hatched from the irradiated eggs and on the performance of the population initiated from irradiated eggs. The study showed that γ-radiation in a range of doses from the background level to 100 Gy had no effect on survival of irradiated eggs. The absorbed dose of 200 Gy was lethal to resting eggs of M. macrocopa. The number of clutches and net reproductive rate (R0) of hatchlings from eggs exposed to radiation were the strongly affected parameters in experiments with individual females...

AIMS: The P2Y6 nucleotide receptor is widely involved in inflammatory responses, and is a promising molecular target for the treatment of inflammatory diseases. Although several P2Y6 receptor antagonists have been developed and evaluated thus far, none has successfully been developed into a therapeutic drug. In this study, we explored new promising compounds that inhibit the human P2Y6 receptor. MAIN METHODS: High-throughput screening (HTS) was used to study the effects of various compounds on human P2Y6 receptors expressed in 1321N1 human astrocytoma cells by monitoring intracellular Ca(2+) concentration ([Ca(2+)]i) levels using an FDSS7000 real-time fluorescence detector...

BACKGROUND & AIMS: Surgical stress provokes protein catabolism and hyperglycaemia that is enhanced in patients with type 2 diabetes (T2DM), and increases perioperative morbidity. This study hypothesized that perioperative administration of high dose intravenous (IV) amino acids (AA) will augment protein balance in T2DM patients receiving tight plasma glucose control via continuous IV insulin compared to standard plasma glucose control via subcutaneous (SC) insulin sliding scale. METHODS: Eighteen patients with well-controlled T2DM (HbA1C% < 7...

In recent years, Gafchromic films are used as an advanced instrument for dosimetry systems. The EBT3 films are a new generation of Gafchromic films. Our main interest is to compare the response of the EBT3 films exposed to gamma rays provided by the Theratron 780C as a conventional radiotherapy system and the Leksell Gamma Knife as a stereotactic radiotherapy system (SRS). Both systems use Cobalt-60 sources, thus using the same energy. However, other factors such as source-to-axis distance, number of sources, dose rate, direction of irradiation, shape of phantom, the field shape of radiation, and different scatter contribution may influence the calibration curve...

Mast cells play crucial roles in the initiation of allergic inflammatory responses by releasing various mediators such as histamines, cytokines, and leukotrienes. In addition, signaling cascade pathways, such as the mitogen-activated protein kinase (MAPK) pathway, contribute to the regulation of mast cell degranulation. Accordingly, different research strategies have been pursued to develop anti-inflammatory and anti-allergic drugs by regulating these signaling pathways. The development of new drugs that inhibit mast cell degranulation may help in the treatment of allergies...

Adaptation to hypoxia requires compensatory mechanisms that affect oxygen (O2) transport and utilization. Decreased hemoglobin (Hb)-O2 affinity is considered part of the physiological adaptive process to chronic hypoxia. This manuscript explores the hypothesis that increased Hb-O2 affinity can complement acute physiological responses to hypoxia by increasing O2 uptake and delivery when compared to normal Hb-O2 affinity during acute severe hypoxia. To test this hypothesis, mice Hb-O2 affinity was increased via oral administration of 70 or 140 mg/kg GBT1118...

Disease outbreaks increase proportionally with increases in intensive aquaculture. Natural products including medicinal plants have been known from thousands of years for treating some human diseases. It is well known that many active compounds are responsible for potential bio-activities. For that reason, there has been considerable interest in the use of medicinal plants in aquaculture with a view to providing safe and eco-friendly compounds for replacing antibiotics and chemical compounds as well as to enhance immune status and control fish diseases...

LNK (SH2B3) is an intracellular adaptor protein that negatively regulates cellular proliferation or self-renewal of hematopoietic stem cells and some other progenitor cells. LNK is also recognized as a key regulator of insulin resistance and inflammatory responses in several tissues and organs. It is unknown the function of LNK in adipose tissue. We previously demonstrated that type 2 diabetes mellitus (T2DM) mouse model had elevated serum free fatty acids (FFAs) levels and increased preadipocyte apoptosis in visceral fat tissue, showing the occurrence of lipotoxicity...

Aquaporin-3 (AQP3), a water and glycerol channel, plays an important role in epidermal function, with studies demonstrating its involvement in keratinocyte proliferation, differentiation and migration and epidermal wound healing and barrier repair. Increasing speculation about the use of histone deacetylase (HDAC) inhibitors to treat skin diseases led us to investigate HDAC's role in the regulation of AQP3. The broad-spectrum HDAC inhibitor, suberolyanilide hydroxamic acid (SAHA) induced AQP3 mRNA and protein expression in a dose- and time-dependent manner in normal keratinocytes...

High-dose methotrexate (HDMTX) plays an important role in the treatment of acute lymphoblastic leukemia (ALL) although there is great inter-patient variability in the efficacy and toxicity of MTX. The relationship between polymorphisms in genes encoding MTX transporters and MTX response is controversial. In the present study, 322 Chinese children with standard- and intermediate-risk ALL were genotyped for 12 polymorphisms. SLCO1B1 rs10841753 showed a significant association with plasma MTX levels at 48 h (P = 0...
