Real-time quantification and supplementation of bioreactor amino acids to prolong culture time and maintain antibody product quality.

Real-time monitoring of cell cultures in bioreactors can enable expedited responses necessary to correct potential batch failure perturbations which may normally go undiscovered until the completion of the batch and result in failure. Currently, analytical technologies are dedicated to real-time monitoring of bioreactor parameters such as pH, dissolved oxygen and temperature, nutrients such as glucose and glutamine, or metabolites such as lactate. Despite the importance of amino acids as the building blocks...


Corrosion protection through naturally occurring films: New insights from iron carbonate.

Despite intensive study over many years, the chemistry and physics of the atomic level mechanisms that govern corrosion are not fully understood. In particular, the occurrence and severity of highly localised metal degradation cannot currently be predicted and often cannot be rationalised in failure analysis. We report a first principles model of the nature of protective iron carbonate films coupled with a detailed chemical and physical characterisation of such a film in a carefully controlled environment. ...

Anisotropic CoFe2O4@Graphene Hybrid Aerogels with High Flux and Excellent Stability as Building Blocks for Rapid Catalytic Degradation of Organic Contaminants in a Flow-Type Setup.

Macroscopic three-dimensional catalytic materials could overcome the poor operability and avoid secondary pollution of common powdery counterparts, especially in flow-type setups. However, conventional isotropic graphene based aerogels and foams have randomly distributed graphene sheets, which may cause the stream erosion and reduce the flux seriously. Herein, for the first time, we design and fabricate a novel anisotropic CoFe2O4@graphene hybrid aerogel (CFO@GA-A) with a hydrothermal synthesis followed by ...


Using Polygenic Profiles to Predict Variation in Language and Psychosocial Outcomes in Early and Middle Childhood.

Purpose Children with poor language tend to have worse psychosocial outcomes compared to their typically developing peers. The most common explanations for such adversities focus on developmental psychological processes whereby poor language triggers psychosocial difficulties. Here, we investigate the possibility of shared biological effects by considering whether the same genetic variants, which are thought to influence language development, are also predictors of elevated psychosocial difficulties during ...

Construction of 3D in vitro models by bioprinting human pluripotent stem cells: challenges and opportunities.

Three-dimensional (3D) printing of biological material, or 3D bioprinting, is a rapidly expanding field with interesting applications in tissue engineering and regenerative medicine. Bioprinters use cells and biocompatible materials as an ink (bioink) to build 3D structures representative of organs and tissues, in a controlled manner and with micrometric resolution. Human embryonic (hESCs) and induced (iPSCs) pluripotent stem cells are ideally able to provide all cell types found in the human body. A limite...

Acute L-DOPA administration reverses changes in firing pattern and low frequency oscillatory activity in the entopeduncular nucleus from long term L-DOPA treated 6-OHDA-lesioned rats.

The pathophysiology of Parkinson's disease (PD) and L-DOPA-induced dyskinesia (LID) is associated with aberrant neuronal activity and abnormal high levels of oscillatory activity and synchronization in several basal ganglia nuclei and the cortex. Previously, we have shown that the firing activity of neurons in the substantia nigra pars reticulata (SNr) is relevant in dyskinesia and may be driven by subthalamic nucleus (STN) hyperactivity. Conversely, low frequency oscillatory activity and synchronization in...

Pro-apoptotic protein BIM as a novel prognostic marker in mantle cell lymphoma.

Mantle cell lymphoma (MCL) is an aggressive B-cell lymphoma. Numerous studies have demonstrated many genetic aberrations in MCL in addition to the characteristic t(11:14), including frequent biallelic deletions of Bim, a pro-apoptotic member of the BCL-2 family. In mice, Bim deletion coupled with cyclin D1 overexpression generates pathologic and molecular features of human MCL. Since the regulation of apoptosis is crucial in MCL pathogenesis, we hypothesize that BIM expression may be associated with tumor c...

Environmental exposures such as smoking and low vitamin D are predictive of poor outcome in cutaneous melanoma rather than other deprivation measures.

Lack of basic resources within a society (deprivation) is associated with increased cancer mortality and this relationship has been described for melanoma. We have previously reported the association of smoking and low vitamin D levels with melanoma death. In this study we further explored the associations of these with melanoma, in addition to deprivation and socio-economic stressors. In this analysis of 2183 population-ascertained primary cutaneous melanoma patients; clinical, demographic and socio-econom...

Using GIS, geostatistics and Fuzzy logic to study spatial structure of sedimentary total PAHs and potential eco-risks; An Eastern Persian Gulf case study.

GIS, geo-statistics and autocorrelation analysis were employed to reveal spatial structure of sedimentary ∑16PAHs. Global Moran's I index outlined significant ∑PAHs clusters for the entire region (Moran's I index =0.62, Z-score = 25.6). Anselin Moran's I index specified locations of the significant low/high spatial clusters. The levels of random and structural variance of ∑PAHs were about 0.083 and 0.154, respectively. Nugget to sill ratio confirmed that ∑PAHs has a moderate level of spatial str...

Using spatially explicit, time-dependent analysis to understand how social factors influence conservation outcomes.

Conservation across human-dominated landscapes requires an understanding of the social and ecological factors driving outcomes. Studies that link conservation outcomes to social and ecological factors have examined temporally static patterns. However, there may be different social and ecological processes driving increases and decreases in conservation outcomes that can only be revealed through temporal analyses. Through a case study of the invasion of Falcataria moluccana in Hawaii, we examined the associa...

Evaluation of weight loss in canine cancer bearing patients undergoing radiation therapy.

Critical weight loss, as defined by ≥5% decrease in body weight, has been associated with increased morbidity and mortality in human patients with cancers of the head and neck. Weight loss has anecdotally been reported to occur frequently in veterinary patients undergoing radiation therapy and is hypothesized to be more severe in patients with cancers of the head and neck, along with those hospitalized during radiation therapy. The primary objective of this retrospective study was to evaluate the occurren...

Studying the effect of structured ostomy care training on quality of life and anxiety of patients with permanent ostomy.

Patients with ostomy are faced with several physical, psychological, and social challenges and need to be prepared to overcome these challenges. Studies have shown that training plays an important role in helping patients to adapt with ostomy, live with it, and improve their psychological well-being and quality of life (QOL). Therefore, the present study aimed to determine the effect of structured ostomy care training on QOL and anxiety of the patients with permanent ostomy. In this randomised clinical tria...

Pure laparoscopic versus open hemihepatectomy: a critical assessment and realistic expectations. A propensity score-based analysis of right and left hemihepatectomies from 9 European tertiary referral centers.

A stronger evidence level is needed to confirm the benefits and limits of laparoscopic hemihepatectomies.

A Retrospective Study of Long-Term Improvement on the Boston Naming Test.

Purpose Lexical retrieval impairment is a universal characteristic of aphasia and a common treatment focus. Although naming improvement is well documented, there is limited information to shape expectations regarding long-term recovery. This was the motivation for a retrospective study of longitudinal data on the Boston Naming Test (BNT; Kaplan, Goodglass, & Weintraub, 1983, 2000). Method BNT scores were analyzed from a heterogeneous cohort of 42 individuals with anomia associated with a range of aphasia ty...

Thiamine and phosphate esters concentrations in whole blood and serum of patients with alcohol use disorder: a relation with cognitive deficits.

In this study, we investigated (1) the effect of chronic and excessive alcohol consumption on whole blood (WB) and serum concentrations of thiamine and its metabolites after supplementation, and (2) the relationship between the perturbations of thiamine metabolism and neuropsychological abilities. WB and serum samples were collected in patients with Alcohol Use Disorder (AUD) and in healthy control subjects (after oral thiamine supplementation, or without supplementation). Thiamine (Th), thiamine monophosp...

The factor structure and construct validity of the parent-reported Inventory of Callous-Unemotional Traits among school-aged children and adolescents.

In this study, we assessed the factor structure and construct validity of the parent-reported Inventory of Callous-Unemotional Traits (ICU) among school-aged children and adolescents, aged 6 to 15 years, in a community setting in Japan (n = 10,936). We investigated 15 models that have been reported in previous studies and used confirmatory factor analyses to determine a model that might actually be the best-fit among these. We then examined the correlations between the score of ICU and the Strengths and Dif...

DLQI-R scoring improves the discriminatory power of Dermatology Life Quality Index in psoriasis, pemphigus and morphea patients.

Dermatology Life Quality Index (DLQI) rates 'not relevant' responses (NRRs) as the item of the questionnaire having no impact on the patients' lives at all. DLQI-R is a recently developed scoring that adjusts the total score of the questionnaire for the number of NRRs indicated by a patient.

Standard vs Cyclic Teriparatide and Denosumab Treatment for Osteoporosis: A Randomized Trial.

In the absence of an intervening antiresorptive agent, cyclic administration of teriparatide does not increase BMD more than standard daily therapy. Since denosumab is a potent antiresorptive agent with a rapid off-effect, we hypothesized that it might be the optimal agent to help maximize bone gains with cyclic teriparatide. In this 3 year protocol, 70 postmenopausal women with osteoporosis were randomized to: 18 months teriparatide followed by 18 months denosumab (Standard) or 3 separate 12 month cycles o...

Clinical performance of the updated trabecular bone score (TBS) algorithm which accounts for the soft tissue thickness: The OsteoLaus Study.

Regional soft tissue may have a noise effect on trabecular bone score (TBS) and eventually alter its estimate. The current TBS software (TBS iNsight®) is based on an algorithm accounting for body mass index (BMI) (TBS ). We aimed to explore the updated TBS algorithm that accounts for soft tissue thickness (TBS ). This study was embedded in the OsteoLaus cohort of women in Lausanne, Switzerland. Hip and lumbar spine (LS) dual-energy X-ray absorptiometry (DXA) scans were performed using Discovery A System (H...

Association between Tumor Multifocality on Multi-parametric MRI and Detection of Clinically-Significant Prostate Cancer in Lesions with Prostate Imaging Reporting and Data System (PI-RADS) Score 4.

To investigate whether presence of multifocality on multi-parametric magnetic resonance imaging (mpMRI) would increase the likelihood of detecting clinically-significant prostate cancer (csPCa) in a PI-RADS 4 lesion.

Developement, characterization and evaluation of topical methotrexate-entrapped deformable liposome on imiquimod-induced psoriasis in a mouse model.

The aim of this study was to prepare and characterize topical methotrexate (MTX) with different percentages (0.05%, 0.1%, 0.25% and 0.5%) entrapped in deformable liposomes using phosphatidylcholine and oleic acid. The effectiveness and sub-acute toxicity of these topical formulations were investigated in imiquimod (IMQ)-induced psoriasis in a mouse model (IMQP). The particle sizes of formulations were around 100 nm with a mean zeta potential of -72.87 mV. The entrapment efficiency (EE%) of MTX in liposomal ...

The SUF system: An ABC ATPase-dependent protein complex with a role in Fe-S cluster biogenesis.

Iron-sulfur (Fe-S) clusters are considered one of the most ancient and versatile inorganic cofactors present in the three domains of life. Fe-S clusters can act as redox sensors or catalysts and are found to be used by a large number of functional and structurally diverse proteins. Here, we cover current knowledge of the SUF multiprotein machinery that synthesizes and inserts Fe-S clusters into proteins. Specific focus is put on the ABC ATPase SufC, which contributes to building Fe-S clusters, and appeared ...

Clinical usefulness of scales for evaluating cognitive impairment in patients with amyotrophic lateral sclerosis.

Cognitive impairment is a common non-motor symptom of amyotrophic lateral sclerosis (ALS); however, scales suitable for detecting cognitive impairment in ALS patients in clinical practice are unclear. In this study, the Mini-Mental State Examination, Frontal Assessment Battery, and Montreal Cognitive Assessment (MoCA) were evaluated in 68 patients with ALS. The patients were classified into 3 groups based on the results of these clinical scales: group N, patients with scores higher than the cut-offs in all ...

Integrating MAES implementation into protected area management under climate change: A fine-scale application in Greece.

Increasing anthropogenic pressures often jeopardize ecosystem integrity and policy-relevant conservation management in protected areas. To harmonize nature conservation with human well-being, EU Biodiversity Strategy to 2020 suggests Mapping and Assessment of Ecosystems and their Services (MAES) as the key concept for environmental planning and management in EU Member States. Applying this procedure is challenging due to its data-demanding and multidisciplinary nature, resulting in the ecoystem services (ES...

Convergence of three parcellation approaches demonstrating cerebellar lobule volume deficits in Alcohol Use Disorder.

Recent advances in robust and reliable methods of MRI-derived cerebellar lobule parcellation volumetry present the opportunity to assess effects of Alcohol Use Disorder (AUD) on selective cerebellar lobules and relations with indices of nutrition and motor functions. In pursuit of this opportunity, we analyzed high-resolution MRI data acquired in 24 individuals with AUD and 20 age- and sex-matched controls with a 32-channel head coil using three different atlases: the online automated analysis pipeline volB...
