Introduction Schizophrenia is a debilitating illness with a chronic impact on social function and daily living. Although various antipsychotics are available, there are still many challenges and unmet needs. Thus, many compounds with diverse mechanisms have been investigated, but all approved antipsychotics still require interactions with dopamine D2 receptors. Areas Covered We searched for investigational drugs using the key words 'dopamine' and 'schizophrenia' in American and European clinical trial registers (clinicaltrials...

Stephen J Pennycook
Over the last three decades the scanning transmission electron microscope (STEM) has gone from a specialized instrument for nanoscale analysis to the microscope of choice for atomic resolution imaging of materials, allowing incoherent high-angle annular dark field (Z-contrast) imaging, coherent phase contrast modes (conventional and annular bright field), electron energy loss and energy dispersive X-ray spectroscopy. All signals are achieving atomic resolution and several are available simultaneously. This would not have been possible without the development of an aberration corrector for the STEM, spearheaded by Ondrej Krivanek in the late 1990s, which finally allowed the benefits of the STEM to translate from "in-principle" to actual daily practice...

The Hickrill Chemical Research Foundation, located north of New York City on the estate of its patrons, Sylvan and Ruth Alice Norman Weil, had a short (1948-59) but productive life. Ruth Alice Weil received a Ph.D. in organic chemistry in 1947, directed by William von Eggers Doering of Columbia University. She intended that Hickrill contribute to cancer chemotherapy while providing resources for Doering's more speculative research. Ultimately, Doering's commitment to theoretical organic chemistry set Hickrill's research agenda...

Previous studies have shown that exercise improves aerobic capacity, muscular functioning, cardiovascular function, walking capacity, and health-related quality of life (QOL) in patients with chronic kidney disease (CKD) and dialysis. Recently, additional studies have shown that higher physical activity contributes to survival and decreased mortality as well as physical function and QOL in patients with CKD and dialysis. Herein, we review the evidence that physical function and physical activity play an important role in mortality for patients with CKD and dialysis...

REVIEW
Roy Moncayo, Helga Moncayo
Classical thinking in endocrine physiology squeezes our diagnostic handling into a simple negative feedback mechanism with a controller and a controlled variable. In the case of the thyroid this is reduced to TSH and fT3 and fT4, respectively. The setting of this tight notion has no free space for any additions. In this paper we want to challenge this model of limited application by proposing a construct based on a systems approach departing from two basic considerations. In first place since the majority of cases of thyroid disease develop and appear during life it has to be considered as an acquired condition...

The Human Genome Project modeled its open science ethos on nematode biology, most famously through daily release of DNA sequence data based on the 1996 Bermuda Principles. That open science philosophy persists, but daily, unfettered release of data has had to adapt to constraints occasioned by the use of data from individual people, broader use of data not only by scientists but also by clinicians and individuals, the global reach of genomic applications and diverse national privacy and research ethics laws, and the rising prominence of a diverse commercial genomics sector...

BACKGROUND: The novel prodrug tenofovir alafenamide delivers the nucleotide reverse transcriptase inhibitor tenofovir to target cells more efficiently at a lower dose than tenofovir disoproxil fumarate, thereby reducing systemic exposure. We compared the efficacy and safety of the two drugs in patients with HBeAg-negative chronic hepatitis B virus (HBV) infection in a non-inferiority study. METHODS: In this ongoing randomised, double-blind, phase 3, non-inferiority study in 105 centres in 17 countries, patients with HBeAg-negative chronic HBV were randomly assigned (2:1) by a computer-generated allocation sequence (block size six), stratified by plasma HBV DNA concentration and previous treatment status, to receive once-daily oral doses of tenofovir alafenamide 25 mg or tenofovir disoproxil fumarate 300 mg, each with matching placebo...

BACKGROUND: Hepatitis C virus (HCV) treatment regimens with direct-acting antivirals have not been extensively studied in patients with decompensated cirrhosis. We assessed patient-reported outcomes (PROs) in patients with decompensated cirrhosis given a fixed-dose combination of sofosbuvir and velpatasvir with and without ribavirin. METHODS: This study was an exploratory analysis of data collected in a randomised, open-label phase 3 trial (ASTRAL-4) in which patients with HCV-related decompensated cirrhosis were randomly assigned to an all-oral fixed-dose combination of sofosbuvir (400 mg) and velpatasvir (100 mg) once daily for 12 weeks, sofosbuvir and velpatasvir plus oral ribavirin (weight-based 1000 mg or 1200 mg) for 12 weeks, or sofosbuvir and velpatasvir for 24 weeks...

BACKGROUND: The latest European Association for the Study of the Liver (EASL) guidelines now recommend that patients with acute hepatitis C virus (HCV) infection should be treated with a combination of sofosbuvir and an NS5A inhibitor for 8 weeks. However, the ideal duration of treatment with interferon-free regimens, particularly in HIV-coinfected individuals, remains unknown. We assessed the efficacy and safety of 6 weeks of ledipasvir-sofosbuvir for acute genotype 1 or 4 HCV in HIV-1-coinfected patients...

Existing crop models produce unsatisfactory simulation results and are operationally complicated. The present study, however, demonstrated the unique advantages of statistical crop models for large-scale simulation. Using rice as the research crop, a support vector machine-based open crop model (SBOCM) was developed by integrating developmental stage and yield prediction models. Basic geographical information obtained by surface weather observation stations in China and the 1:1000000 soil database published by the Chinese Academy of Sciences were used...

Importance: Although oral metronomic chemotherapy is often used in progressive pediatric solid malignant tumors, a literature review reveals that only small single-arm retrospective or phase 1 and 2 studies have been performed. Skepticism abounds because of the lack of level 1 evidence. Objectives: To compare the effect of metronomic chemotherapy on progression-free survival (PFS) with that of placebo in pediatric patients with primary extracranial, nonhematopoietic solid malignant tumors that progress after at least 2 lines of chemotherapy...

Genetics is an important piece of every individual health puzzle. The completion of the Human Genome Project sequence has deeply changed the research of life sciences including nutrition. The analysis of the genome is already part of clinical care in oncology, pharmacology, infectious disease and, rare and undiagnosed diseases. The implications of genetic variations in shaping individual nutritional requirements have been recognised and conclusively proven, yet routine use of genetic information in nutrition and dietetics practice is still far from being implemented...

INTRODUCTION: Volume overload and the renin-aldosterone-angiotensin system (RAAS) are 2 major factors contributing to hypertension (HTN) among hemodialysis (HD) patients. Although volume-dependent components of HTN can be corrected by appropriate volume removal, a proportion of HD patients experience elevated blood pressure (BP) despite achieving euvolemic and ideal dry weight. METHOD AND ANALYSIS: A single center, prospective, randomized, parallel design, single-blind trial will be conducted in the Malaysian state of Kelantan among postdialysis euvolemic hypertensive patients that are on regular dialysis at least 3 times a week...
