https://www.readbyqxmd.com/read/28640636/cross-reactive-synbody-affinity-ligands-for-capturing-diverse-noroviruses
#1
Nidhi Gupta, John C Lainson, Paul E Belcher, Luhui Shen, Hugh S Mason, Stephen Albert Johnston, Chris W Diehnelt
Noroviruses are the most common cause of acute gastroenteritis in the developed world. Noroviruses are a diverse group of nonenveloped RNA viruses that are continuously evolving. This leads to the rise of immunologically distinct strains of the same genotype on a frequent basis. This diversity presents a unique challenge for detection and tracking of new strains, with the continuous need for new norovirus affinity ligands. Our group developed a family of bivalent synbody affinity ligands using a virus-like particle (VLP) from the 2006 GII...

Shuji Kawasaki, Dhisa Minerva, Keiko Itano, Takashi Suzuki
We consider ordinary differential equation (ODE) model for a pathway network that arises in extracellular matrix (ECM) degradation. For solving the ODEs, we propose applying the mass conservation law (MCL), together with a stoichiometry called doubling rule, to them. Then it leads to extracting new units of variables in the ODEs that can be solved explicitly, at least in principle. The simulation results for the ODE solutions show that the numerical solutions are indeed in good accord with theoretical solutions and satisfy the MALs...

BACKGROUND: Since 2000, the United Nations' Millennium Development Goals, which included a goal to improve maternal health by the end of 2015, has facilitated significant reductions in maternal morbidity and mortality worldwide. However, despite more focused efforts made especially by low- and middle-income countries, targets were largely unmet in sub-Saharan Africa, where women are plagued by many challenges in seeking obstetric care. The aim of this review was to synthesise literature on barriers to obstetric care at health institutions in sub-Saharan Africa...

Pancreatic ductal adenocarcinoma (PDAC) is a devastating disease with an overall 5-year survival rate of less than 7%. After many years of basic and clinical research efforts, pancreatic cancer patients presenting with locally advanced, unresectable tumors remain a therapeutic challenge. Despite the lack of high quality randomized controlled trials, perioperative/ neoadjuvant treatment strategies seem to be beneficial in these patients. At present the FOLFIRINOX regimen, which was established in the palliative setting, is increasingly recognized as the backbone of neoadjuvant therapy for locally advanced PDAC...

BACKGROUND: Atrial tachycardia (AT) and atrial fibrillation (AF) are common in pacemaker patients and are associated with bad prognoses. OBJECTIVE: The purpose of this study was to evaluate atrial antitachycardia pacing impact on AT/AF-induced atrial remodeling, measured by early recurrence of AT/AF (ERAF) and by change in left atrial diameter (LAD), and to evaluate the impact of AT/AF duration on ERAF incidence. METHODS: Pacemaker patients were randomized to dual-chamber pacing (Control DDDR: 385 patients), managed ventricular pacing (MVP: 398 patients), or atrial antitachycardia pacing plus MVP (DDDRP+MVP: 383 patients)...

Folliculogenesis is a process that depends on angiogenesis, in which VEGF and Notch signaling pathway members are involved. Although this pathway is present in preantral and antral follicular structures during the second stage of folliculogenesis, this association has not been described. Therefore, this study aimed to identify VEGF and Notch2 in ovary structures of infantile rats after induction of follicular development with a gonadotropin stimulus. In order to explore this possibility we analyzed rat ovary morphology from days 10-25 after birth; subsequently, the transition from preantral follicle to an antral stage was analyzed by the induction of follicular development with equine chorionic gonadotropin (eCG) and VEGF and Notch were identified in the rat ovary by fluorescence...

Toni C Saad
In her paper 'Cosmetic surgery and conscientious objection', Minerva rightly identifies cosmetic surgery as an interesting test case for the question of conscientious objection in medicine. Her treatment of this important subject, however, seems problematic. It is argued that Minerva's suggestion that a doctor has a prima facie duty to satisfy patient preferences even against his better clinical judgment, which we call Patient Preference Absolutism, must be regarded with scepticism. This is because (1) it overlooks an important distinction regarding autonomy's meaning and place in clinical practice, and (2) it makes obsolete the important concepts of expert clinical judgment and beneficence...

OBJECTIVE: CETP (cholesteryl ester transfer protein) plays an important role in lipoprotein metabolism; however, whether inhibition of CETP activity can prevent cardiovascular disease remains controversial. APPROACH AND RESULTS: We generated CETP knockout (KO) rabbits by zinc finger nuclease gene editing and compared their susceptibility to cholesterol diet-induced atherosclerosis to that of wild-type (WT) rabbits. On a chow diet, KO rabbits showed higher plasma levels of high-density lipoprotein (HDL) cholesterol than WT controls, and HDL particles of KO rabbits were essentially rich in apolipoprotein AI and apolipoprotein E contents...

Allatotropins (AT) are neuropeptides with pleotropic functions on a variety of insect tissues. They affect processes such as juvenile hormone biosynthesis, cardiac rhythm, oviduct and hindgut contractions, nutrient absorption and circadian cycle. The present work provides experimental evidence that AT elicits immune responses in two important mosquito disease vectors, Anopheles albimanus and Aedes aegypti. Hemocytes and an immune-competent mosquito cell line responded to AT by showing strong morphological changes and increasing bacterial phagocytic activity...

3,4-methylenedioxymethamphetamine (MDMA) increases sociality in humans and animals. Release of serotonin (5-HT) is thought to play an important role in the increase in social behaviors, but the mechanisms underlying these effects are poorly understood. Despite the advantages of nonhuman primate models, no studies have examined the mechanisms of the social effects of MDMA in nonhuman primates. The behavior and vocalizations of four group-housed squirrel monkeys were examined following administration of MDMA, its enantiomers, and methamphetamine...

A broad range of health benefits have been attributed to resveratrol (RSV) supplementation in mammalian systems, including the increases in longevity. Nonetheless, despite the growing number of studies performed with RSV, the molecular mechanism by which it acts still remains unknown. Recently, it has been proposed that inhibition of the oxidative phosphorylation activity is the principal mechanism of RSV action. This mechanism suggests that RSV might induce mitochondrial dysfunction resulting in oxidative damage to cells with a concomitant decrease of cell viability and cellular life span...

Eugenia Yiannakopoulou
Minimally invasive surgery has an established role in the treatment of patients with pancreatic neuroendocrine tumors (pNETs). Enucleation is an established treatment option for insulinomas. The necessity of organ sparing surgery is well established in the case of multiple pNETs. A number of studies have demonstrated the efficacy and safety of laparoscopic surgery for the treatment of pNETs. However, pNETs are rare, and large studies focusing on pNET patients are difficult to be designed unless multicenter experience is collected...
