Using an object-choice task, we measured the relative quantity discrimination ability of Asian elephants. Two zoo-housed elephants were given auditory cues of food being dropped into two containers (Nonvisible condition), and in one condition they could also see the food on top of the containers (Visible condition). Elephants received sets of varying ratios and magnitudes. We found that the elephants chose the greater quantity of food significantly above chance in both the Visible and Nonvisible conditions. Additionally, we found the elephants' ability to discriminate between quantities decreased as the ratio, and not the absolute difference, between the quantities increased, which is predicted by the accumulator model. We also compare our findings to those from a study using the same methods with African savanna elephants and found that the two species performed at similar levels, but given our small sample size it is difficult to make strong species-level conclusions. In discussing our results, we consider differences between the two species' wild environments as well as the types of sensory cues provided in human care, and we provide recommendations for extensions of this work.

Identification and characterization of a novel thermostable amidase (Xam) with wide pH tolerance and broad-spectrum substrate specificity.

Xam was identified from non-thermophilic Xinfangfangia sp. DLY26 and its acyl transfer activity was investigated. Recombinant Xam was optimally active at 60°C and pH 9.0. The enzyme had a half life of 18h at 55°C and maintained more than 60 % of its maximum activity in the range of pH 3.0-11.0. Additionally, Xam exhibited broad substrate specificity towards aliphatic, aromatic, and heterocyclic amides.

These unique properties make Xam a promising biocatalyst for production of important hydroxamic acids at elevated temperatures.

High-throughput 16S rRNA gene sequencing analysis revealed that Firmicutes, Bacteroidetes, and Proteobacteria are the most abundant bacterial phyla (64.08%). Prevotella group 7 was the most abundant genus in digester YL9 and YL10 (69.72% and 26.96%, respectively) using vegetable waste raw materials. Trichococcus exhibited the highest abundance (14.55%) in YL1 digester using sheep and pig manure. Clostridium sensu stricto 1 (13.89%) and Synergistaceae_uncultured (15.52%) comprised the highest abundances in digester YL5 with mixed raw materials (i.e., dairy manure, sheep manure, and human feces). In addition, Proteiniphilum and Pseudomonas exhibited the highest abundances among bacterial genera in YL4 digester using pig manure. Methanomicrobiales was the most dominant archaeal communities, ranging from 13.35% to 81.34% in abundance. Methanocorpusculum exhibited dominant abundances in all digesters using various raw materials. Methanogenium was the most abundant archaeal genera in YL4 and YL6 digesters, which consume pig manure as primary raw material. In addition, Methanosarcina and Methanosaeta exhibited the highest abundances in digester YL1 (55.03%) and YL9 (51.40%), respectively. Moreover, fermentation temperatures and pH both contributed to the archaeal and bacterial community structures in all the investigated digesters. Specially, fermentation temperature showed positive correlation with the abundances of Synergistaceae_uncultured, Methanogenium, and Methanosaeta, and pH was positively correlated with the abundances of Prevotella group 7 and Methanosarcina abundances.The management of massive anterior mediastinal masses (AMM) is challenging. With the burgeoning role of extracorporeal membrane oxygenation support (ECMO) beyond the confines of salvage therapy, more trained clinicians are adopting it as a bridge for high-risk procedures or situations where temporary respiratory or cardiac support is required. We report our experience with using ECMO in the management of massive AMM in this case series of three patients sharing their clinical details and the lessons learned from them.Recovery is a commonly used concept in both professional and everyday contexts. Yet despite its extensive use, it has not drawn much philosophical attention. In this paper, I question the common understanding of recovery, show how the concept is inadequate, and introduce new and much needed terminology. I argue that recovery glosses over important distinctions and even misrepresents the process of moving away from malady as "going back" to a former state of health. It does not invite important nuances needed to distinguish between biomedical, phenomenological, and social perspectives. In addition, I claim that there are many conditions where we are making use of the concept of recovery, although the person recovered from the condition in question, has not regained the same degree of soundness. I show how the concept of recovery leads to conceptual discrepancies that can result in worsening patients' conditions. To gain a fuller understanding, I propose to rethink the direction of the process in question. I define the process of moving away from malady as a move forward towards a new state of soundness. I also suggest three terms, corresponding to different perspectives, to describe this movement forward 'curing' (biomedical perspective), 'healing' (first-person perspective), and 'habilitating' (social perspective). This new terminology provides a more nuanced understanding of the states of both malady and soundness and an attentiveness as to how they differ and relate.

We aim to investigate the relationship between pulmonary function and imaging parameters with symptom-related patient-reported outcome measures (PROs).

We included 65 patients of rheumatoid arthritis (RA) and connective tissue disease (CTD) with and without interstitial lung disease (ILD) into this cross-sectional study. click here We evaluated the relationship between FVC, DLco, and PROs and compared to HRCT findings. PROs included visual analogue scale for breathing, modified Borg scale, medical research council dyspnea scale, St. George's respiratory questionnaire (SGRQ), Leicester cough questionnaire, and Short Form 36 quality of life (SF-36 QoL).

The mean age was 57.4 ± 9.7 and 61.9% (39/65) of patients had an established ILD. In RA-ILD group, SGRQ score was higher (p < 0.001) and SF-36 physical functioning score was lower (p = 0.02) than CTD-ILD group. In RA group, there was a significant correlation between FVC and SF-36 role functioning/physical score (r = 0.724, p = 0.012). In CTD group, SF-36 general health score was correlated with both FVC (r = 0.
