The hydropower capacity of China ranks first in the world and accounts for approximately 20% of the total energy production in the country. While hydropower has substantially contributed to meeting China's renewable energy targets and providing clean energy to rural areas, the development of hydropower in China has been met with significant controversy. Ecologically, hydro projects alter the landscape, with potential impacts to the country's aquatic biodiversity. Over the past four decades in China, various mainstream opinions and misunderstandings have been presented concerning how to alleviate the negative impacts of hydro projects on aquatic ecosystems...

Innovative treatment technologies and management methods are necessary to valorise the constituents of wastewater, in particular nutrients from urine (highly concentrated and can have significant impacts related to artificial fertilizer production). The FP7 project, ValuefromUrine, proposed a new two-step process (called VFU) based on struvite precipitation and microbial electrolysis cell (MEC) to recover ammonia, which is further transformed into ammonium sulphate. The environmental and economic impacts of its prospective implementation in the Netherlands were evaluated based on life cycle assessment (LCA) methodology and operational costs...

Alongside the best-known applications of brain-computer interface (BCI) technology for restoring communication abilities and controlling external devices, we present the state of the art of BCI use for cognitive assessment and training purposes. We first describe some preliminary attempts to develop verbal-motor free BCI-based tests for evaluating specific or multiple cognitive domains in patients with Amyotrophic Lateral Sclerosis, disorders of consciousness, and other neurological diseases. Then we present the more heterogeneous and advanced field of BCI-based cognitive training, which has its roots in the context of neurofeedback therapy and addresses patients with neurological developmental disorders (autism spectrum disorder and attention-deficit/hyperactivity disorder), stroke patients, and elderly subjects...

Organ-on-chip (OOC) platforms have attracted attentions of pharmaceutical companies as powerful tools for screening of existing drugs and development of new drug candidates. OOCs have primarily used human cell lines or primary cells to develop biomimetic tissue models. However, the ability of human stem cells in unlimited self-renewal and differentiation into multiple lineages has made them attractive for OOCs. The microfluidic technology has enabled precise control of stem cell differentiation using soluble factors, biophysical cues, and electromagnetic signals...

BACKGROUND: Borrelia recurrentis is the causative agent of louse-borne relapsing fever, endemic to the Horn of Africa. New attention was raised in Europe, with the highest number of cases (n = 45) reported among migrants in 2015 in Germany and sporadically from other European countries. So far only one genome was sequenced, hindering the development of specific molecular diagnostic and typing tools. Here we report on modified culture conditions for B. recurrentis and the intraspecies genome variability of six isolates isolated and cultured in different years in order to explore the possibility to identify new targets for typing and examine the molecular epidemiology of the pathogen...

Laparoscopic surgery technology continues to advance. However, much less attention has been focused on how alteration of the laparoscopic surgical environment might improve clinical outcomes. We conducted a randomized, 2 × 2 factorial trial to evaluate whether low intraperitoneal pressure (IPP) (8 mmHg) and/or warmed, humidified CO2 (WH) gas are better for minimizing the adverse impact of a CO2 pneumoperitoneum on the peritoneal environment during laparoscopic surgery and for improving clinical outcomes compared to the standard IPP (12 mmHg) and/or cool and dry CO2 (CD) gas...

REVIEW

Over the past two decades, biomass-derived and biodegradable polylactide (PLA) has sparked tremendous attention as a sustainable alternative to traditional petroleum-derived polymers for diverse applications. Unfortunately, the current applications of PLA have been mainly limited to biomedical and commodity fields, mostly because the poor heat resistance (resulting from low melting temperature) and hydrolysis stability make it hard to use as an engineering plastic. Stereocomplexation between enantiomeric poly(l-lactide) (PLLA) and poly(d-lactide) (PDLA) opens a new avenue toward PLA-based engineering plastics with improved properties...

Identifying compulsive consumption of marijuana in association with another mental disorder (attentional defcit disorder, bipolar disorder, depression or psychosis) presents the challenge of clarifying validated therapeutic strategies, especially within the teen population, in which it shows the highest prevalence. The ever-increasing prevalence and the need for regional treatments, demand that we approach this health matter as a public health issue. The ideological con?icts related to the necessary decriminalization of consumption and the current debate on the medical use of marijuana often confuse the urgent need to establish effective therapeutic strategies for the population affected by this mental disorder...

Photodetectors based on low-dimensional materials have attracted tremendous attention due to the high sensitivity and compatibility with conventional semiconductor technology. However, up-until-now, developing low-dimensional phototransistors with high responsivity and low dark currents over broadband spectra still remains a great challenge due to the trade-offs in the potential architectures. In this work, we report a hybrid phototransistor consisting of a single In2O3 nanowire as channel material and a multilayer WSe2 nanosheet as the decorating sensitizer for photodetection...

In the United States, valvular heart disease (VHD) has a prevalence of 2.5%, most commonly presenting as aortic stenosis (AS) or mitral valve regurgitation (MR) and increasingly observed to be of a degenerative etiology. Women frequently have latent symptoms despite significant disease, and it is therefore pertinent to consider both clinical symptoms and imaging findings for decision-making on treatment. Indeed, significant advances have been made in noninvasive imaging allowing for more accurate diagnosis and disease prognostication...
