Chemical modification of neuropeptide Y for human Y1 receptor targeting in health and disease.

As a very abundant neuropeptide in the brain and widely distributed peptide hormone in the periphery, neuropeptide Y (NPY) appears to be a multisignaling key peptide. Together with peptide YY, pancreatic polypeptide and the four human G protein-coupled receptor subtypes hY1R, hY2R, hY4R and hY5R it forms the NPY/hYR multiligand/multireceptor system, which is involved in essential physiological pro...

Exploring resting state connectivity in patients with psychotic depression.

Severe depression is associated with high morbidity and mortality. Neural network dysfunction may contribute to disease mechanisms underlying different clinical subtypes. Here, we apply resting-state functional magnetic resonance imaging based measures of brain connectivity to investigate network dysfunction in severely depressed in-patients with and without psychotic symptoms.

The lifetime prevalence of hospitalised head injury in Scottish prisons: A population study.

There is mounting evidence that associates brain injury and offending behaviour, and there is a need to understand the epidemiology of head injury in prisoners in order to plan interventions to reduce associated disability and risk of reoffending. This is the first study to determine the lifetime prevalence of hospitalised head injury (HHI) in a national population of current prison inmates. In ad...

Bottom-up, integrated -omics analysis identifies broadly dosage-sensitive genes in breast cancer samples from TCGA.

The massive genomic data from The Cancer Genome Atlas (TCGA), including proteomics data from Clinical Proteomic Tumor Analysis Consortium (CPTAC), provides a unique opportunity to study cancer systematically. While most observations are made from a single type of genomics data, we apply big data analytics and systems biology approaches by simultaneously analyzing DNA amplification, mRNA and protei...

The effect of sodium butyrate and cisplatin on expression of EMT markers.

Histone modifications play a key role in the epigenetic regulation of gene transcription in cancer cells. Histone acetylations are regulated by two classes of enzymes, histone acetyltransferases (HATs) and histone deacetylases (HDACs). HDACs are increased in ovarian carcinomas and they are involved in carcinogenesis and resistance to chemotherapeutic agents. In our study we investigated anticancer...

Sleep disturbances are mainly improved by deep brain stimulation of the subthalamic nucleus.

Nomogram Development and External Validation for Predicting the Risk of Lymph Node Metastasis in T1 Colorectal Cancer.

Predicting lymph node metastasis (LNM) risk is crucial in determining further treatment strategies following endoscopic resection of T1 colorectal cancer (CRC). This study aimed to establish a new prediction model for the risk of LNM in T1 CRC patients.

Atezolizumab in Patients with Pretreated Urothelial Cancer: a Korean Single-Center, Retrospective Study.

Treatment targeting immune checkpoint with PD-1/PD-L1 inhibitors has demonstrated efficacy and tolerability in the treatment of metastatic urothelial carcinoma (mUC). We investigated the efficacy and safety of atezolizumab in mUC patients who failed platinum-based chemotherapy.

Prospective Validation of The Korean Cancer Study Group Geriatric Score (KG)-7, a Novel Geriatric Screening Tool, in Older Patients with Advanced Cancer Undergoing First-line Palliative Chemotherapy.

The purpose of this study was to prospectively validate the Korean Cancer Study Group Geriatric Score (KG)-7, a novel geriatric screening tool, in older patients with advanced cancer planned to undergo first-line palliative chemotherapy.

Higher Age Puts Lung-Cancer Patients at Risk for Not Receiving Anti-cancer Treatment.

We aimed to determine the demographic and epidemiologic variables that are associated with no treatment in lung cancer patients.

Alterations in PD-L1 Expression Associated with Acquisition of Resistance to ALK Inhibitors in ALK-Rearranged Lung Cancer.

The purpose of this study was to evaluate the relationships between the resistance of anaplastic lymphoma kinase (ALK)‒positive non-small cell lung cancer (NSCLC) to ALK inhibitors and the programmed cell death-1/programmed cell death-ligand 1 (PD-L1) pathway, we evaluated alterations in PD-L1 following acquisition of resistance to ALK inhibitors in ALK-positive lung cancer.

Li-Fraumeni syndrome presenting as cutaneous melanoma in a child: case report and review of literature.

Li-Fraumeni syndrome (LFS) is a rare, autosomal dominant inherited cancer predisposition syndrome associated with germline mutation of the TP53 tumor suppressor gene [1, 2]. It is traditionally characterized by early-onset of multiple primary tumors: sarcoma, breast cancer, brain tumor, leukemia, and adrenocortical carcinoma. [2] Classically, LFS is clinically diagnosed when a patient present with...

Integration of Neural Reward Processing and Appetite-Related Signaling in Obese Females: Evidence From Resting-State fMRI.

The reward-related regions have been considered a crucial component in the regulation of eating behavior. Furthermore, appetite-related regions associated with reward can influence eating behaviors through altered functional activity related to food in brain areas associated with emotion, memory, sensory processing, motor function, and cognitive control.

Brain injury, behaviour support, and family involvement: putting the pieces together and looking forward.

Behavioral, neurochemical and brain oscillation abnormalities in an experimental model of acute liver failure.

Hepatic encephalopathy (HE) represents a brain dysfunction caused by both acute and chronic liver failure, and its severity deeply affects the prognosis of patients with impaired liver function. In its pathophysiology, ammonia levels and glutamatergic system hyperactivity seem to play a pivotal role in the disruption of brain homeostasis. Here, we investigate important outcomes involved in behavio...

Anxiety in obesity: is neuroinflammation the critical link?

Effects of early life stress on cocaine conditioning and AMPA receptor composition are sex-specific and driven by TNF.

Exposure to early life adversity can predispose adolescents to the formation of substance abuse disorders. In rodents, early stressors such as repeated maternal separation (MS) impact AMPAR activity in the prefrontal cortex (PFC) and nucleus accumbens (NAc), regions involved in drug-cue association after cocaine-induced conditioned place preference (CPP). Notably, previous reports suggest that the...

Personality and EEG correlates of reactive social behavior.

Reactive, as opposed to proactive, behavior during social interactions has been investigated in the study of aggression, but it is virtually unexplored in relation to other kinds of social behavior. Little is known about brain underpinning of these processes. In this study, we used a virtual interaction model to manipulate the emotional display of the interaction partner and to register actor's re...
