AbstractTuberculosis (TB) patients present dysregulated immunity, iron metabolism and anaemia of inflammation. In this study, circulatory cytokines, trace metals, and iron-related proteins (hepcidin, ferroportin, transferrin, DMT1, Nramp1, ferritin, ceruloplasmin, hemojuvelin, aconitase, transferring receptor) were monitored in case (active tuberculosis patients: ATB) and control (non-tuberculosis: NTB and healthy) study populations (n=72, male, 42.94 mean age (16-83)). Using serum elemental and cytokine levels, a partial least square discriminate analysis model (PLS-DA) was built and variables with a VIP score of >0.6 were selected as important markers. A biosignature of IL-13, IL-12(p70), IFN-γ, IL-10, IL-5, IL-18, IL-4, Selenium, and Aluminium clustered ATB away from controls. Interestingly, low iron and selenium levels, while high copper and aluminum levels were observed in ATB subjects. All the important serum cytokines were positively correlated in ATB subjects. A low abundance of transferrin, ferroportin, and hemojuvelin, while higher ferritin and ceruloplasmin levels explained an altered iron metabolism in ATB subjects which partially resolved upon completion of treatment. Further, the identified biosignature in TB patients, that explained anemia of inflammation, along with perturbed iron homeostasis could be useful targets for the development of host-directed adjunct therapeutics.

The widely used techniques for analyzing the quality of powdered food products focus on targeted detection with a low-throughput screening of samples. Owing to potentially significant health threats and large-scale adulterations, food regulatory agencies and industries require rapid and non-destructive analytical techniques for the detection of unexpected compounds present in products. Accordingly, shortwave-infrared hyperspectral imaging (SWIR-HSI) for high throughput authenticity analysis of almond powder was investigated in this study. Two different varieties of almond powder, adulterated with apricot and peanut powder at different concentrations, were imaged using the SWIR-HSI system. A one-class classifier technique, known as data-driven soft independent modeling of class analogy (DD-SIMCA), was used on collected data sets of pure and adulterated samples. A partial least square regression (PLSR) model was further developed to predict adulterant concentrations in almond powder. Classification results from DD-SIMCA yielded 100% sensitivity and 89–100% specificity for different validation sets of adulterated samples. The results obtained from the PLSR analysis yielded a high determination coefficient (R2) and low error values (<1%) for each variety of almond powder adulterated with apricot; however, a relatively higher error rates of 2.5% and 4.4% for the two varieties of almond powder adulterated with peanut powder, which indicates the performance of quantitative analysis model could vary with sample condition, such as variety, originality, etc. PLSR-based concentration mapped images visually characterized the adulterant (apricot) concentration in the almond powder. These results demonstrate that the SWIR-HSI technique combined with the one-class classifier DD-SIMCA can be used effectively for a high-throughput quality screening of almond powder regarding potential adulteration.

Blood stasis (BS) is characterized as a disorder of blood circulation. In traditional Korean medicine (TKM), it is viewed as a cause factor of diseases such as multiple sclerosis and stroke. This study investigated differences in the plasma metabolites profiles of subjects displaying BS or non-BS patterns. Thirty-one patients with cerebral infarction diagnosed with BS and an equal number of sex- and age-matched non-BS patients were enrolled. Metabolic profiling was performed using UPLC-MS. The ratio of subjects with a rough pulse and purple coloration of the tongue was higher in patients presenting with BS pattern. Through metabolomics analysis, 82 metabolites that differed significantly between the BS and non-BS pattern were identified, and the two groups were significantly separated using an orthogonal partial least square-discriminant analysis model(P<0.001). Of these 82 metabolites, acetyl carnitine, leucine, kynurenine, phosphocholine, hexanoyl carnitine, and decanoyl carnitine were present in significantly higher levels in patients with a BS pattern than those with a non-BS pattern. Our results also demonstrated that seven plasma metabolites, including acyl-carnitines and kynurenine, were associated with a BS pattern, suggesting that variant plasma metabolic profiles may serve as a biomarker for diagnosis of BS in patients with cerebral infarction.

Purpose The purpose of this paper is to investigate how attitudinal, normative and control beliefs influence scientists’ article sharing through ResearchGate. Design/methodology/approach A survey method was employed to examine a research model of scientists’ article sharing through ResearchGate. A total of 264 survey responses from biological scientists in the USA were used to evaluate the research model by using partial least square based structural equation modeling. Findings The results showed that scientists’ attitudinal beliefs (i.e. perceived relationship, reputation and risk), normative beliefs (i.e. subjective norm, perceived academic culture and community norm of article sharing) and control belief (i.e. perceived ease of use) all significantly affect their attitudes toward article sharing and article sharing intentions through ResearchGate. Research limitations/implications The theory of planned behavior (TPB) was used to develop the research model, and the specific research constructs from prior literature were incorporated in the model. The TPB and related research constructs nicely explained biological scientists’ article sharing through ResearchGate. Practical implications This study suggests that academic libraries can better promote their scientists’ article sharing through digital platforms such as institutional repositories as well as scholarly social media. This can be achieved by emphasizing its benefits, including potential relationships or collaborations, positive academic reputation and community norms of article sharing, and by decreasing scientists’ concerns about copyright infringements and effort expectancy involved in article sharing. Originality/value As one of the initial studies in scientists’ article sharing through ResearchGate, this study provides a holistic picture of how attitudinal, normative and control beliefs all affect scientists’ article sharing through ResearchGate.
