The lake system present in the basin also allowed for the presence of marshland vegetation. The assessment of the availability of edible plant parts reveals that early Homo could have found a high number of resources in marshland and riparian environments throughout the year. Mediterranean woodlands and deciduous forests also provided numerous edible plant parts. During dry periods, the availability of plant resources decreased heavily, but the prevalence of marshland and riparian vegetation and of forested vegetation in the areas of higher altitude could have sustained hominin communities during harsher climatic periods. However, the disappearance of the lake system and an increase of aridity after the Mid-Pleistocene Transition and during the Middle Pleistocene probably led to an impoverishment of plant resources available to early Homo in the Guadix-Baza Basin.

Bronchodilators are the cornerstone for treating patients with chronic obstructive pulmonary diseases (COPD), although some studies have shown that dual bronchodilators may exacerbate incidence of adverse cardiovascular events. Here, we evaluated the cardiopulmonary safety of indacaterol/glycopyrronium (IND/GLY) using a meta-analysis.

We searched PubMed, OVID, Cochrane Library and Web of Science databases, using "indacaterol/glycopyrronium", "indacaterol/glycopyrrolate", "IND/GLY", "QVA149", "chronic obstructive pulmonary diseases", "COPD", "chronic obstructive airway disease", "chronic obstructive lung disease" as key words. Acute exacerbation of COPD and FEV

as indicators of pulmonary function and occurrence of hypertension, atrial fibrillation, myocardial infarction and heart failure as indicators of cardiovascular safety.

A total of 23 articles, comprising 21,238 participants, were included in the analysis. FEV

values were significantly different compared to IND/GLY and single bronchodilator the events.During the COVID-19 pandemic, public health agencies and decision-makers have used social media to disseminate information, encourage changes to behaviour and promote community supports and resources. Their communications have served to educate the public on risks and initiate the widespread adoption of public health measures to 'flatten the curve'. We conducted a content analysis of COVID-19 Tweets by Canadian public health accounts during the first 6 months of the pandemic to explore differences in Tweeting practices by geography and identify opportunities to improve risk communication. We found that Canadian public health accounts in particular geographic settings did not always apply best practices for health communication. Tweeting practices differed considerably between jurisdictions with varying burdens of COVID-19. Going forward, Tweets authored by public health accounts that promote behaviour change and community-building ought to be utilized whenever risks to health are high to reflect an increase in disease transmission requiring intervention. Our study highlights the need for public health communicators to deliver messaging that is relevant for the levels of risk that their audiences are encountering in a given geographic context.A natural antioxidant emulsifier, tea polysaccharide conjugate (TPC), was isolated from Chin brick tea. The impact of TPC on β-carotene stability and bioaccessibility in oil-in-water nanoemulsions was assessed. TPC exhibited strong antioxidant activity and could be used to fabricate stable nanoemulsions (d less then 140 nm). The extent of lipid digestion was considerably lower for lipid droplets coated by TPC (68%) than Tween 80 (94%) or whey protein isolate (WPI) (89%), probably because TPC formed interfacial layers that hindered the access of lipases to lipids. The chemical stability of β-carotene in TPC-nanoemulsions was markedly higher than in those formulated with Tween 80 or WPI due to the high antioxidant activity of TPC. The bioaccessibility of β-carotene (20-30%) was independent of emulsifier type. TPC from Chin brick tea can therefore be used as a dual-purpose functional ingredient in emulsified foods.The dual coated yeast capsules for anthocyanin encapsulation and stabilization were fabricated. Anthocyanins were preloaded in hollow yeast capsules, and then the dual coating was performed by deposition of opposite charged polysaccharides using layer-by-layer technique. The combination of positively charged chitosan and negatively charged chondroitin sulfate was found to confer the yeast capsules with the highest encapsulation efficiency and retention rate of anthocyanins. Additionally, the coated yeast capsules featured high tolerance to environmental stresses (i.e., oxygen, ascorbic acid, and heat) and therefore effectively inhibited the degradation of anthocyanins. These stabilizing effects were related to the formation of high penetration barrier provided by the double layers of polysaccharides, as well as the enhanced hydrophobic microenvironment in the capsules. Further development of the polysaccharide-coated yeast capsules may hold promise for the controlled delivery of other water-soluble bioactive components.Arsenic speciation analysis in dried seaweeds was carried out using an on-line HPLC-UV-thermo-oxidation-HG-AFS system. iFSP1 Species separated and quantified were arsenite [As(III)], arsenate [As(V)], monomethylarsonic acid (MMA), dimethylarsinic acid (DMA) and different arsenosugars. Extraction efficiency ranged between 38 and 83%. Chromatographic separation was achieved in gradient elution mode using (NH4)2CO3 as mobile phase in the pH range 9-10.3. Total As concentration was quantified by ICP-MS after microwave digestion. Limits of detection were in the range 3.0 to 6.0 ng g-1 for the species under study based on peak height and the relative standard deviation was less then 8% at 10 µg L-1 As. The accuracy of the procedure was verified by analyzing the CRM BCR-279 Ulva lactuca. Results for total As were in agreement with the certified values. The HPLC-(UV)-HG-AFS system resulted suitable for quantification of eight As compounds. Results showed that arsenosugars are the most abundant compounds in the investigated seaweeds.Bean-based fermentation foods are usually ripened in open environment, which would lead to inconsistencies in flavor and quality between batches. The physicochemical metabolism and microbial community of seasonal broad bean paste (BBP) were compared to distinguish discriminant metabolites and unique taxa, as well as their specific reasons for different flavor and quality in this study. link2 Here, we found that environmental variables led to the seasonal distribution of microbiota, and differential microorganisms further contributed to the inconsistency of flavor quality, in which Lactobacillales was responsible for the higher titratable acid and amino acid nitrogen concentration in winter pei, while Saccharomycetales benefited the formation of volatile flavor substances in autumn pei. Additionally, we compared the effect of different combinations of Lactobacillales with Zygosaccharomyces rouxii on the quality of BBP, and found that W. confusa was more suitable for BBP fermentation rather than T. halophilus in terms of sensory characteristics and physicochemical metabolites.Deuterated vitamin D standards are used commonly as internal standards in LC-MS/MS analysis of vitamin D3 and 25-hydroxyvitamin D3 in food. However, the use of various eluent additives, such as methylamine, formic acid and ammonium formate, also contributes to matrix effects and the performance of analysis by affecting accuracy and robustness. For the first time, continuous post-column infusion experiments of isotopically labelled vitamin D3-[d6] were performed to evaluate ion-suppression in a wide variety of food (salmon, cheese, pork fat, pork meat, and egg yolk). Furthermore, results collected using five analytical methods, employing DAD/UV and MS/MS-detectors, were evaluated with in-house and standardised reference materials. The matrix effect was significant when analysing vitamin D3 in most food matrices using the deuterium labelled internal standard. Even though the use of the 13C5-labelled internal standard reduced matrix effects, a standardised method is needed to agree on the true value of vitamin D in food.This study elucidated thermal denaturation profile of myosin in sea cucumber longitudinal muscle. Sea cucumber myosin structure was different from fish at its head/tail junction which could not be cleaved by EDTA. However, sea cucumber myosin in salt-dissolved form could be cleaved into heavy meromyosin (HMM) and light meromyosin (LMM) segments. Although sea cucumbers lived in cold water, its myosin stability was comparable to tropical tilapia, more stable than rainbow trout (a cold water fish). Upon heating, the sea cucumber myosin lost its salt-solubility rapidly, even before losing its ATPase activity. The quick loss of salt-solubility suggested a quick denaturation at light meromyosin region as revealed by chymotryptic digestion. link3 These results suggested that sea cucumber myosin is consisted of very stable head region and unstable tail region, which is important for choosing proper heating conditions for sea cucumber processing.The development of highly efficient performance matrix for protein adsorption and scalable throughput adsorbent is highly desired, especially in pharmaceuticals and food industries. In this work, we present a simple methodology to prepare a nanofibrous membrane based surface molecular imprinted matrix (MIP) for selective separation of lysozyme. The MIP was developed by coating carboxylated poly (vinyl alcohol-co-ethylene) nanofibrous mat (EVOH-CCA NFM) with a near infrared (NIR)-light responsive polydopamine (PDA) layer. The open porous nanofibrous structure and a thin PDA layer endowed the MIPs with adsorption capacity (500 mg.g-1) within 150 min. The developed surface MIPs not only showed imprinting factor (IF = 4) with reusability upon 5 cycles, but also capability of extracting lysozyme from egg-white directly. The MIPs showed controlled release of extracted lysozyme triggered by the NIR-light responsive property of the PDA layer. Moreover, the released lysozyme possesses good bioactivity, evidenced by efficient decomposition of micrococcus bacterial cell wall.We investigate the hypothesis that proteins and peptides are thermally degraded by hydrolytic bond cleavage of amide bonds, hence yielding shorter peptides as main degradation products. A series of fifteen pentapeptides with varying sequences was subjected to heating. Products were investigated by targeted UHPLC-ESI-tandem mass spectrometry and targeted analysis revealed formation of 2,5-diketopiperazines, di- and tri-peptides. Relative quantities of the thermal degradation were determined to show that hydrolytic cleavage is an important, however not dominant degradation pathway. A series of dietary intact proteins were subjected to heating and products formed analyzed by MALDI-TOF mass spectrometry. For the majority of proteins larger degradation products with m/z values between 900 and 2500 could be observed, which we tentatively assign as hydrolytic cleavage products. For coffee globulin a series of eleven short peptides formed through thermal hydrolytic cleavage could be unambiguously identified formed through thermal proteolysis.
