A 72-year-old man with prostate cancer (stage T3b, Gleason score 7) treated by radical prostatectomy was found to have biochemical failure (prostate-specific antigen 8.5 ng/mL) and a suspicious growing nodularity at the left prostate bed on MRI. F-fluorocholine PET/CT failed to demonstrate any site of uptake suggestive of malignancy. A bone scan did exclude bone metastases. Ga-PSMA PET/CT revealed various positive lymph nodes in the supraclavicular, mediastinal, and hilar regions. This was confirmed on F-DCFPyl PET/CT, with the addition of a suspicious right axillary lymph node...

Generalized anxiety disorder (GAD) is common in patients with asthma. High levels of GAD may lead both to exacerbation of the condition and poor management. However, the physiological mechanisms of GAD in asthma patient is unclear. This study investigated the associations between the diurnal rhythm of sputum cytokines, salivary cortisol, α-amylase and GAD in asthma patients. Patients with co-morbid GAD and asthma showed higher sputum IL-1 AUC, sputum IL-6 AUC and sAA AUC. And there were positive correlations between Hamilton anxiety scale (HAMA) scores and sputum IL-1 AUC concentrations (r=0...

Understanding genetic events that lead to cancer initiation and progression remains one of the biggest challenges in cancer biology. Traditionally, most algorithms for cancer-driver identification look for genes that have more mutations than expected from the average background mutation rate. However, there is now a wide variety of methods that look for nonrandom distribution of mutations within proteins as a signal for the driving role of mutations in cancer. Here we classify and review such subgene-resolution algorithms, compare their findings on four distinct cancer data sets from The Cancer Genome Atlas and discuss how predictions from these algorithms can be interpreted in the emerging paradigms that challenge the simple dichotomy between driver and passenger genes...

BACKGROUND: While most psychiatric diagnoses are based on simple counts of symptoms, some symptoms may be sign of a more severe mental syndrome than others. This calls for validated estimates of the relative severity specific symptoms imply within a disorder. We focused on four diagnostic disorders: Manic Episode (ME), Major Depressive Episode (MDE), Post-traumatic Stress Disorder (PTSD) and Generalized Anxiety Disorder (GAD). Symptom-specific severity parameters were estimated, and validated by examining their association with levels of self-reported disability in daily activities over and above the number of symptoms...

Task control is an executive control mechanism that facilitates goal-directed task selection by suppressing irrelevant automatic "stimulus-driven" behaviors. In the current study, we test the hypothesis that less efficient task control in individuals diagnosed with obsessive-compulsive disorder (OCD) is associated with OCD symptoms, and specifically, with the inability to inhibit unwanted behaviors in OCD. Thirty-five healthy controls, 30 participants with OCD, and 26 participants with generalized anxiety disorder (GAD) completed the object-interference (OI) task to measure task control, the stop-signal task to measure response inhibition, and the arrow-flanker task to evaluate executive abilities not contingent upon task control...

OBJECTIVE: Monogenic diabetes, a young-onset form of diabetes, is often misdiagnosed as type 1 diabetes, resulting in unnecessary treatment with insulin. A screening approach for monogenic diabetes is needed to accurately select suitable patients for expensive diagnostic genetic testing. We used C-peptide and islet autoantibodies, highly sensitive and specific biomarkers for discriminating type 1 from non-type 1 diabetes, in a biomarker screening pathway for monogenic diabetes. RESEARCH DESIGN AND METHODS: We studied patients diagnosed aged 30 years or younger, currently younger than 50 years, in two U...

Lymphocyte function-associated antigen 1 (LFA-1) affinity and avidity changes have been assumed to mediate adhesion to intercellular adhesion molecule-1 for T-cell conjugation to dendritic cells (DC). Although the T-cell receptor (TCR) and LFA-1 can generate intracellular signals, the immune cell adaptor protein linker for the activation of T cells (LAT) couples the TCR to downstream events. Here, we show that LFA-1 can mediate both adhesion and de-adhesion, dependent on receptor clustering. Although increased affinity mediates adhesion, LFA-1 cross-linking induced the association and activation of the protein-tyrosine kinases FAK1/PYK1 that phosphorylated LAT selectively on a single Y-171 site for the binding to adaptor complex GRB-2-SKAP1...

Candida albicans adhesion and proliferation on denture bases may lead to denture stomatitis, which is a common and recurrent problem in denture wearers. The goal of this study was to assess the inhibitory effect of thymoquinone incorporated in the polymethyl methacrylate denture base material against Candida albicans. Eighty acrylic resin specimens were fabricated and divided into eight groups (n = 10) according to thymoquinone concentrations of 0.5%, 1%, 1.5%, 2%, 2.5%, 3%, and 5% of acrylic powder. Two methods were used to evaluate the effect of thymoquinone on Candida albicans: the slide count and the serial dilution test...

Eating is a learned process. Our desires for specific foods arise through experience. Both electrical stimulation and optogenetic studies have shown that increased activity in the lateral hypothalamus (LH) promotes feeding. Current dogma is that these effects reflect a role for LH neurons in the control of the core motivation to feed, and their activity comes under control of forebrain regions to elicit learned food-motivated behaviors. However, these effects could also reflect the storage of associative information about the cues leading to food in LH itself...

The diagnosis of canine leishmaniosis (CanL) is complex due to its variable clinical manifestations and laboratory findings. The availability of vaccines to prevent CanL has increased the complexity of diagnosis, as serological tests may not distinguish between naturally infected and vaccinated dogs. Current practices of prevaccination screening are not sufficiently sensitive to detect subclinically infected dogs, resulting in the vaccination of infected animals, which may lead to disease in vaccinated dogs that are also infectious to sand flies...

INTRODUCTION: The vagus nerve stimulation (VNS) is used for treatment of drug-resistant epilepsy but laryngeal side effects are common. We tried to improve VNS by modifying the implantation procedure. The aim was to reduce the rate of side effects that have prevented using VNS to its full capacity. METHODS: We operated on 74 pediatric patients for VNS device implantation using a modified surgical protocol incorporating lower neck incision for electrode placement and 36 patients who were operated by standard technique were used for control group...

Several neurological syndromes have been recognized associated to GAD antibodies. Among those disorders, cerebellar ataxia (CA) is one of the most common, along with stiff-person syndrome. Patients with GAD associated CA present with a progressive pancerebellar syndrome, with a subacute or chronic evolution, along with other neurological manifestations such as stiffness, oculomotor dysfunction, epilepsy, and cognitive dysfunction. These symptoms may be preceded by the so-called "brainstem attacks", where manifestations consistent with transient dysfunction of the brainstem may be observed...

Chronic idiopathic urticaria (CIU) is one of the mysteries of dermatology. An association between spontaneous CIU and contact allergy sensitization is possible. In this study, we aimed to test the hypothesis that contact allergy might play a role in disease in CIU patients. Furthermore, we examined if patch testing should be routinely performed in patients with chronic urticaria (CU). Ultimately, we concluded that patch testing should be included among the diagnostic procedures for CU.
