At present, high-solids anaerobic digestion of sewage sludge has drawn great attention due to the superiority of its small land area footprint and low energy consumption. However, a high organic loading rate may cause acids accumulation and ammonia inhibition, thus leading to an inhibited pseudo-steady state in which electron transfer through interspecies hydrogen transfer (IHT) between acetogens and methanogens is blocked. In this study, adding 50 mg/g TS (total solid) magnetite clearly reduced the accumulation of short-chain fatty acids and accelerated methane production by 26...

OBJECTIVE: As exercise intolerance and exercise-induced myalgia are commonly encountered in metabolic myopathies, functional screening tests are commonly used during the diagnostic work-up. Our objective was to evaluate the accuracy of isometric handgrip test (IHT) and progressive cycle ergometer test (PCET) to identify McArdle disease and myoadenylate deaminase (MAD) deficiency and to propose diagnostic algorithms using exercise-induced lactate and ammonia variations. METHODS: A prospective sample of 46 patients underwent an IHT and a PCET as part of their exercise-induced myalgia and intolerance evaluation...

Introduction: Research into healthcare delivered via interprofessional healthcare teams (IHTs) has uncovered that IHT can improve patient satisfaction, enhance collaborative behaviors, reduce clinical error rates, and streamline management of care delivery. Importantly, these achievements are attained by IHTs that have been trained via interprofessional education (IPE). Research indicates that interprofessional healthcare team training must be contextualized to suit the demands of each care context...

OBJECTIVES: Breast cancer stem cells (BCSCs) contribute to breast cancer progression, relapse, and treatment resistance. Identification of the natural inhibitory components of BCSCs is therefore critical for clinical treatment. Here, we investigated whether isoharringtonine (IHT) had inhibitory effects on BCSCs in breast cancer cell lines. METHODS: HCC1806, HCC1937, and MCF7 cells were treated with IHT. The proliferation and the migration of cells were detected by MTS assay and wound healing migration assay, respectively...

The hypothesis that an atypical hemispheric specialization is associated to developmental dyslexia (DD) is receiving renewed interest, lending some support to Orton’s theory. In this article, we investigated whether interhemispheric transfer processes (IHT) are likely to be involved in developmental dyslexia. In this study, we tested 13 children with developmental dyslexia and 13 matched controls (aged 8 to 13 years) in four different tasks. In a tactile transfer task, the dyslexic children’s performance was less accurate...

Monitoring of the respiration using the electrocardiogram (ECG) is desirable for the simultaneous study of cardiac activities and the respiration in the aspects of comfort, mobility, and cost of the healthcare system. This paper proposes a new approach for deriving the respiration from single-lead ECG based on the iterated Hilbert transform (IHT) and the Hilbert vibration decomposition (HVD). The ECG signal is first decomposed into the multicomponent sinusoidal signals using the IHT technique. Afterward, the lower order amplitude components obtained from the IHT are filtered using the HVD to extract the respiration information...

Atomic force microscope (AFM) is an analytical instrument which is used to study the surface structure and morphology of materials. The AFM can measure and observe samples either in air or liquid environment. However, the standard AFM requires a long time to acquire accurate images and data. In our work, the compressive sensing (CS) was applied in order to reduce the imaging time, lower the interactions between the probe and the sample, finally avoid sample damage in AFM. Three samples (PAA film, TGG1 grating and BOPP film) were used as the testing samples...

Monitoring intracranial pressure in comatose patients with severe traumatic brain injury (TBI) is considered necessary by most experts. Acute intracranial hypertension (IHT), when severe and sustained, is a life-threatening complication that demands emergency treatment. Yet, secondary anoxic-ischemic injury after brain trauma can occur in the absence of IHT. In such cases, adding other monitoring modalities can alert clinicians when the patient is in a state of energy failure. This article reviews the mechanisms, diagnosis, and treatment of IHT and brain hypoxia after TBI, emphasizing the need to develop a physiologically integrative approach to the management of these complex situations...

The impacts of ZVI on microbial community diversity in an anaerobic assay with high organic loading were investigated. The relative abundance of bacteria, archaea, and the functional methyl coenzyme-M reductase (mcrA) gene were investigated using high-throughput sequencing, and variations in their quantity were determined by qPCR. The results showed that ZVI significantly increased both the relative abundance and quantity of Methanobacteriales and Methanosarcinales during hydrogenotrophic and acetoclastic methanogenesis...

BACKGROUND: Hospitalization is a common method to intensify care for patients experiencing a psychiatric crisis. A short-term, specialised, out-patient crisis intervention by a Crisis Resolution Team (CRT) in the Netherlands, called Intensive Home Treatment (IHT), is a viable intervention which may help reduce hospital admission days. However, research on the (cost-)effectiveness of alternatives to hospitalisation such as IHT are scarce. In the study presented in this protocol, IHT will be compared to care-as-usual (CAU) in a randomized controlled trial (RCT)...

BACKGROUND: Recently, increased tumor incidence and cancer-related mortality have been reported among patients with obstructive sleep apnea (OSA). Intermittent hypoxia (IH), the hallmark feature of OSA, contributes to the metastasis of tumors. However, the molecular mechanisms by which tumor metastasis is accelerated by OSA-like IH remain to be elucidated. METHODS: C57BL/6 J male mice were subjected to intravenous injection of B16F10 melanoma cells before receiving IH treatment...

BACKGROUND: Transfer of critically ill patients within the hospital is commonly associated with adverse incidents, but, despite this, no standardised training exists on how to carry out this task. Very little information is published in the literature on the learning needs of staff undertaking these transfers, and this limits our ability to provide a focused and appropriate educational intervention. AIMS: This study aimed to explore the organisational, environmental and individual issues that increase risk to patients during intrahospital transport (IHT) and to explore the potential educational solutions to these issues as articulated by these practitioners...

OBJECTIVE: Interhospital transfers (IHTs) to tertiary care centers are linked to lower operative mortality in vascular surgery patients. However, IHT incurs great health care costs, and some transfers may be unnecessary or futile. In this study, we characterize the patterns of IHT at a tertiary care center to examine appropriateness of transfer for vascular surgery care. METHODS: A retrospective review was performed of all IHT requests made to our institution from July 2014 to October 2015...

OBJECTIVE: A locally advanced Gleason 4 + 4 prostate cancer patient who was on self-medication with intermittent anti-androgen monotherapy (iAAm) over 14 years suggested that raised testosterone was not dangerous and this suggestion needed investigating. PATIENTS: Others who were on AA continuously were recruited to ongoing audit of intermittent hormone therapy (IHT) and iAAm outcomes were compared with intermittent LHRH therapy (iLHRH or iMAB). RESULTS: Between 1994 and 2007, 111 patients sought IHT because of side effects of treatment...

BACKGROUND: The use of interactive health technology (IHT) is a promising pathway to tackle self-management problems experienced by many chronically ill patients, including solid organ transplant (Tx) patients. Yet, to ensure that the IHT is accepted and used, a human-centered design process is needed, actively involving end users in all steps of the development process. A first critical, predevelopment step involves understanding end users' characteristics. This study therefore aims to (a) select an IHT platform to deliver a self-management support intervention most closely related to Tx patients' current use of information and communication technologies (ICTs), (b) understand Tx patients' overall willingness to use IHT for self-management support, and investigate associations with relevant technology acceptance variables, and (c) explore Tx patients' views on potential IHT features...

Great effort has recently been devoted to the preparation of nanoscale surfaces on titanium-based implants to achieve clinically fast osteoinduction and osseointegration, which relies on the unique characteristics of the nanostructure. In this work, we used induction heating treatment (IHT) as a rapid oxidation method to fabricate a porous nanoscale oxide layer on the Ti6Al4V surface for better medical application. Well-distributed vertical nanopillars were yielded by IHT for 20-35 s on the alloy surface. The composition of the oxides contained rutile/anatase TiO2 and a small amount of Al2 O3 between the TiO2 grain boundaries (GBs)...
