In vitro and in vivo experiments are widely used for studying the metabolism of new psychoactive substances (NPS). The availability of such data is required for toxicological risk assessments and development of urine screening approaches. This study investigated the in vitro metabolism of the five pyrrolidinophenone-derived NPS alpha-pyrrolidinobutyrophenone (alpha-PBP), alpha-pyrrolidinopentiothiophenone (alpha-PVT), alpha-pyrrolidinohexanophenone (alpha-PHP), alpha-pyrrolidinoenanthophenone (alpha-PEP, PV8), and alpha-pyrrolidinooctanophenone (alpha-POP, PV9)...

Within gastrointestinal malignancies, primary hepatocellular carcinoma and pancreatic ductal adenocarcinoma (PDAC) are frequently associated with visceral thromboses (VT). Thrombus formation in the portal (PVT), mesenteric (MVT), or splenic vein (SVT) system leads to portal hypertension and intestinal ischemia. VT in PDAC may convey a risk of increased distal thrombosis and poses therapeutic uncertainty regarding the role of anticoagulation. An increasing number of reports describe VT associated with PDAC. It is possible that early diagnosis of these events may help reduce morbidity and speculatively improve oncologic outcomes...

BACKGROUND: Protein Z (PZ) is a vitamin K-dependent factor that is synthesized mainly by the liver. It acts as an activator of serpin, the protein Z-dependent inhibitor (ZPI), which inhibits factor Xa. The potential role of alterations in protein Z and/or ZPI levels in the pathogenesis of thrombotic and/or hemorrhagic diseases has been previously investigated, but results have been conflicting. The study aim was to evaluate the role of PZ/ZPI polymorphisms in the development of prosthetic valve thrombosis (PVT)...

Effort testing is a standard element in adult neuropsychological assessment. Research examining performance validity tests (PVTs) has focused on adults. The purpose of this descriptive study was to examine direct and embedded PVTs in children and adolescents. The Test of Memory Malingering (TOMM), a stand-alone PVT, was compared to two embedded measures of effort: California Verbal Learning Test-Children's Version/Second Edition (CVLT-C/II) Recognition Discriminability and Reliable Digit Span (RDS). The sample consisted of 119 children and adolescents referred for outpatient assessment...

RATIONALE: The paraventricular nucleus of the thalamus (PVT) has been shown to mediate cue-motivated behaviors, such as sign- and goal-tracking, as well as reinstatement of drug-seeking behavior. However, the role of the PVT in mediating individual variation in cue-induced drug-seeking behavior remains unknown. OBJECTIVES: This study aimed to determine if inactivation of the PVT differentially mediates cue-induced drug-seeking behavior in sign-trackers and goal-trackers...

This commentary focuses on novel findings by Clark et al. (2017) published in eNeuro, which show that dopamine D2 receptors (D2Rs) in the paraventricular nucleus of the thalamus (PVT) are involved in cocaine sensitization. We extend the discussion on how their findings contribute to our understanding of the role of the PVT in drug seeking by providing new insight on the role of the PVT in the regulation of food-seeking and fear responses. We also consider the significance of the neuroanatomical findings reported by Clark et al...

Portal vein thrombosis (PVT) is an uncommon condition usually associated with hypercoagulable states or liver cirrhosis. PVT due to sports-related injuries is rarely reported and, to the best of our knowledge, only two cases have been reported thus far. Brazilian jiu-jitsu (BJJ) is a form of martial arts and is considered very safe with minimal risk for injury. It has growing popularity worldwide. Here, we report the first case of PVT secondary to abdominal trauma related to the practice of (BJJ) in an otherwise healthy 32-year-old man with no other traditional risk factors for PVT...

Severe thrombocytopenia (platelets <50 x109 /L) is associated with very poor outcome of patients with myelofibrosis (MF). Since patients with primary myelofibrosis (PMF) differ from patients with post-essential thrombocythemia (PET-MF) and post-polycythemia vera myelofibrosis (PPV-MF), we aimed to evaluate the significance of low platelets among these patients. We present clinical characteristics and outcome of patients with either PMF, PPV-MF, or PET-MF, and thrombocytopenia who presented to our institution between 1984 and 2015...

Prosthetic valve thrombosis (PVT) is a life-threatening complication in pregnant women with mechanical prosthetic heart valves. Thrombolytic therapy (TT) has evolved as an effective treatment alternative to surgery, which is associated with very high maternal and fetal mortality and morbidity in these patients. Acute ischemic stroke may rarely occur during TT for PVT. Here, we present a pregnant patient who was complicated with cerebral thromboembolism during TT for PVT and successfully managed with continuation of TT...
