The rostromedial caudate (rmCD) of primates is thought to contribute to reward value processing, but a causal relationship has not been established. Here we use an inhibitory DREADD (Designer Receptor Exclusively Activated by Designer Drug) to repeatedly and non-invasively inactivate rmCD of macaque monkeys. We inject an adeno-associated viral vector expressing the inhibitory DREADD, hM4Di, into the rmCD bilaterally. To visualize DREADD expression in vivo, we develop a non-invasive imaging method using positron emission tomography (PET)...

New antidiabetic drugs are being developed today that expand the range of pharmacological intervention, in particular for patients with type 2 diabetes (imeglimin, semaglutide, dulaglutide, FGF 21 analogue). At the same time innovations take place that "better" the well-proven molecules, they offer new application forms we have no experience of diabetology (osmotic pump for exenatide, faster acting insulin aspart). New properties are brought by just the change of concentration (insulin glargine in a concentration of 300 U/ml), unexpected positive results are also brought by new fixed-ratio combinations of antidiabetics (fixed-ratio combination of insulin degludec and liraglutide, fixed-ratio combination of insulin glargine and lixisenatide)...

P Mascheroni, R Penta
We investigate the impact of microvascular geometry on the transport of drugs in solid tumors, focusing on the diffusion and consumption phenomena. We embrace recent advances in the asymptotic homogenization literature starting from a double Darcy, double advection-diffusion-reaction system of partial differential equations that is obtained exploiting the sharp length separation between the intercapillary distance and the average tumor size. The geometric information on the microvascular network is encoded into effective hydraulic conductivities and diffusivities, which are numerically computed by solving periodic cell problems on appropriate microscale representative cells...

BACKGROUND: Genetic polymorphisms of drug metabolisms by cytochrome P450 (P450s) could affect drug response, attracting particular interest in the pharmacogenetics. Due to the importance of CYP2C19* 17 allele and its capability of super- fast metabolism and also lack of information about distribution of the alleles in Iranian population, this research aimed to use High Resolution Melting (HRM) method compared to PCR-RFLP for genotyping healthy Iranian population. METHODS: Blood samples were collected from 100 healthy Iranian volunteers...

REVIEW
Francesco Marras, Paolo Tranquilli Leali
: Painful symptomatology in the skeletal system can be found in various pathological conditions and can be either localised or diffused. Bone tenderness is common in those who are of an elderly age. TREATMENT STRATEGY: Patients should be informed of the possible causes of their pain and the different therapies that could alleviate it; furthermore they should be encouraged to have an active role in their therapy. It is necessary to prevent the onset of the pain (by the clock) by considering the biological half-life, the bioavailability and the duration of action of the therapy...

OBJECTIVE: Gastrointestinal bleedings are the most frequently occurring reason for medication-related hospital admissions, which are potentially preventable. We implemented a clinical decision support system that recommends to prescribe gastrointestinal prophylaxis in patients with an increased risk according to the Dutch guideline. Our primary objective was to determine whether the implementation resulted in improved compliance with this guideline for gastrointestinal prophylaxis. A secondary objective was to determine whether implementation resulted in a reduction of the number of drug safety alerts...

BACKGROUND: Sex trading is a recognized risk factor for human immune deficiency virus infection and other sexually transmitted infections among non-injecting drug users (NIDUs). However, very little research has addressed the factors associated with sex trading among male NIDUs in Myanmar. METHODS: A cross-sectional study was conducted from January to February 2010 using the respondent-driven sampling method. In total, 210 NIDUs aged between 18 and 49 years, with no history of injecting drug use, and who used non-injected illicit drugs in the last 6 months were recruited...

BACKGROUND: Medication errors represent a noteworthy source of harm to patients. In recent years, several systematic reviews have assessed the frequency and causes of these events, as well as other factors such as commonly associated drugs, their incidence in different specialties, and their consequences to patients. Despite this past literature, there remains a need to study discrepancies between these reviews and establish the current state of the evidence. The planned review will bring together, compare, and contract existing evidence related to the occurrence of medication errors in acute and continuing/long-term care settings...

REVIEW
Erik Sveberg Dietrichs, Georg Sager, Torkjel Tveita
Rewarming from accidental hypothermia is often complicated by hypothermia-induced cardiac dysfunction, calling for immediate pharmacologic intervention. Studies show that although cardiac pharmacologic support is applied when rewarming these patients, a lack of updated treatment recommendations exist. Mainly due to lack of clinical and experimental data, neither of the international guidelines includes information about pharmacologic cardiac support at temperatures below 30 °C. However, core temperature of accidental hypothermia patients is often reduced below 30 °C...

This study examines the risk factors predicting non-prescribed stimulant use (NPSU) among adolescents, with an emphasis on whether such factors are reflective of instrumental (e.g., studying) and/or recreational (e.g., partying) drug consumption settings. Using data from Monitoring the Future (2011), we employed a series of logistic regression models to establish predictors of 12-month self-reported Adderall or Ritalin use without a doctor's note among eighth and tenth graders. Whereas studies of college students have found NPSU to correlate with instrumental motives and productivity-related demands, we find no association between NPSU and indicators of academic strain for this younger sample...

Matrix metalloproteinase (MMP)-12 plays a key role in the development of aneurysm. Like other members of MMP family, MMP-12 is produced as a proenzyme, mainly by macrophages, and undergoes proteolytic activation to generate an active form. Accordingly, molecular imaging of the MMP-12 active form can inform of the pathogenic process in aneurysm. Here, we developed a novel family of fluorescent probes based on a selective MMP-12 inhibitor, RXP470.1 to target the active form of MMP-12. These probes were stable in complex media and retained the high affinity and selectivity of RXP470...
