Cocrystals are crystalline single phase materials composed of two or more different molecular and/or ionic compounds generally in a stoichiometric ratio which are neither solvates nor simple salts. If one of the components is an active pharmaceutical ingredient (API), the term pharmaceutical cocrystal is often used. There is a growing interest among drug development scientists in exploring cocrystals, as means to address physicochemical, biopharmaceutical and mechanical properties and expand solid form diversity of the API...

Among the thousands of chemicals having potential to enter the environment, the NORMAN network has identified at least 700 substances categorized into 20 classes in the European surface waters. Pesticides, pharmaceuticals, disinfection by-products, wood preservation and industrial chemicals are the prominent classes. Since the impact of these substances on aquatic life and human health might be dramatic, action is urgently required at multiple levels; one of them is just related to the development of more and more sensible and selective analytical methods...

INTRODUCTION: Despite the well-documented harmful effects of smoking, many cancer patients continue to smoke. Smoking cessation is critical to address in this population given the associated increase in treatment toxicity, risk of second primary tumors, decrease in treatment response and higher disease-specific and all-cause mortality with continued smoking following a cancer diagnosis. This review seeks to summarize the latest recommendations and guidelines on smoking cessation treatment for patients diagnosed with cancer, and the evidence behind those recommendations...

Passive and active chronic cigarette smoking (CS) remains an international epidemic and a key risk factor for cardiovascular disease (CVD) development. CS-induced cardiac damage is divided into two major and interchangeable mechanisms: (1) direct adverse effects on the myocardium causing smoking cardiomyopathy and (2) indirect effects on the myocardium by fueling comorbidities such as atherosclerotic syndromes and hypertension that eventually damage and remodel the heart. To date, our understanding of cardiac remodeling following acute and chronic smoking exposure is not well elucidated...

Extracellular vesicles (EVs) are a newly-discovered way by which cells communicate with their neighbors, as well as transporting cargos which once were considered to be limited by membrane barriers, including membrane proteins, cytosolic proteins and RNA. The discovery of platelet-derived EVs (P-EVs), the most abundant EVs in human blood, has been a very tortuous process. At first, P-EVs were identified as nothing but 'platelet dust', and subsequent research did not progress smoothly because of the limited research techniques to study EVs...

In this review, we present the latest developments in plant systems biology with particular emphasis on plant genome-scale reconstructions and multi-omics analyses. Understanding multicellular metabolism is far from trivial and 'omics' data are difficult to interpret in the absence of a systems framework. 'Omics' data appropriately integrated with genome-scale reconstructions and modelling facilitates our understanding of how individual components interact and influence overall cell, tissue or organisms function...

Few diseases blur the margins between their childhood and adult-onset varieties as much as optic neuritis. This report will review our state of knowledge of pediatric optic neuritis, as well as its relationship to the latest consensus definitions of neuroinflammatory disease. Current diagnostic and treatment options will be explored, as well as our potential to uncover an understanding of pediatric optic neuritis through systematic prospective studies. The risk of evolving multiple sclerosis is probably less than in adults, but pediatric optic neuritis is more likely to be an initial manifestation of acute disseminated encephalomyelitis...

Quantifying behavior is a challenge for scientists studying neuroscience, ethology, psychology, pathology, etc. Until now, behavior was mostly considered as qualitative descriptions of postures or labor intensive counting of bouts of individual movements. Many prominent behavioral scientists conducted studies describing postures of mice and rats, depicting step by step eating, grooming, courting, and other behaviors. Automated video assessment technologies permit scientists to quantify daily behavioral patterns/routines, social interactions, and postural changes in an unbiased manner...

REVIEW
Pierre LeVan, Burak Akin, Jürgen Hennig
The development of highly accelerated fMRI acquisition techniques has led to novel possibilities to monitor cerebral activity non-invasively and with unprecedented temporal resolutions. With the emergence of dynamic connectivity and its ability to provide a much richer characterization of brain function compared to static measures, fast fMRI may yet play a crucial role in tracking dynamically varying networks. In spite of the dominance of slow hemodynamic contributions to the BOLD signal, high temporal sampling rates nevertheless improve the measurement of physiological noise, yielding an exceptional sensitivity for the detection of periods of transient connectivity at time scales of a few tens of seconds...

BACKGROUND: Due to the negative outcomes of medication non-adherence, interventions to improve adherence have been the focus of countless studies. The congruence between adherence-related patient characteristics and interventions may partly explain the variability of effectiveness in medication adherence studies. In their latest update of a Cochrane review reporting inconsistent effects of adherence interventions, the authors offered access to their database for sub-analysis. We aimed to use this database to assess congruence between adherence-related patient characteristics and interventions and its association with intervention effects...

Plasmodium species cause malaria by proliferating in human erythrocytes. Invasion of immunologically privileged erythrocytes provides a relatively protective niche as well as access to a rich source of nutrients. Plasmodium spp. target erythrocytes of different ages, but share a common mechanism of invasion. Specific engagement of erythrocyte receptors defines target cell tropism, activating downstream events and resulting in the physical penetration of the erythrocyte, powered by the parasite's actinomyosin-based motor...

Baoqing Pei, Wei Wang, Yubo Fan, Xiumei Wang, Fumio Watari, Xiaoming Li
Soft tissue engineering has been developed as a new strategy for repairing damaged or diseased soft tissues and organs to overcome the limitations of current therapies. Since most of soft tissues in the human body are usually supported by collagen fibers to form a three-dimensional microstructure, fiber-reinforced scaffolds have the advantage to mimic the structure, mechanical and biological environment of natural soft tissues, which benefits for their regeneration and remodeling. This article reviews and discusses the latest research advances on design and manufacture of novel fiber-reinforced scaffolds for soft tissue repair and how fiber addition affects their structural characteristics, mechanical strength and biological activities in vitro and in vivo...

REVIEW
Vishal B Gohil, Jason B Klapman
Pancreas cancer is a fourth-leading cause of cancer death in the USA and its incidence is rising as the population is aging. The majority of patients present at an advanced stage due to the silent nature of the disease and treatment have focused more on palliation than curative intent. Gastroenterologists have become integral in the multidisciplinary care of these patients with a focus on providing endoscopic palliation of pancreas cancer. The three most common areas that gastroenterologists palliate endoscopically are biliary obstruction, cancer-related pain, and gastric outlet obstruction...

Advances in our understanding of the mechanisms driving castration-resistant prostate cancer have promoted the development of several new drugs including androgen receptor-directed therapy and chemotherapy. Concomitant docetaxel treatment at the beginning of hormonal therapy for metastatic prostate cancer has resulted in longer overall survival than with hormonal therapy alone. Elucidating an appropriate treatment sequence using these therapies is important for maximizing clinical benefit in castration-sensitive and castration-resistant prostate cancer patients...

Robotic-assisted laparoscopic surgery in urology is an ever progressing field, and boundaries are constantly broken with the aid of new technology. Advancements in instrumentation have given birth to the era of robotic laparoendoscopic single-site technique (R-LESS). R-LESS however, has not gained widespread acceptance due to technical hurdles such as adequate triangulation, robotic arm clashing, decreased access for the bedside assistant, lack of wrist articulation, continued need for an axillary/accessory port, lack of robust retraction, and ergonomic discomfort...
