This study aimed to evaluate the effect of probiotic administration on obese and ageing models. Sprague Dawley rats were subjected to high-fat diet (HFD) and injected with D-galactose to induce premature ageing. Upon 12 weeks of treatment, the faecal samples were collected and subjected to gas chromatography-mass spectrophotometry (GC-MS) analysis for metabolite detection. The sparse partial least squares discriminant analysis (sPLS-DA) showed a distinct clustering pattern of metabolite profile in the aged and obese rats administered with probiotics Lactobacillus plantarum DR7 and L. reuteri 8513d, particularly with a significantly higher concentration of allantoin. Molecular docking simulation showed that allantoin promoted the phosphorylation (activation) of adenosine monophosphate-activated kinase (AMPK) by lowering the substrate free energy of binding (FEB) and induced the formation of an additional hydrogen bond between Val184 and the substrate AMP. Allantoin also suppressed cholesterol biosynthesis by either inducing enzyme inhibition, occupying or blocking the putative binding site to result in non-spontaneous substrate binding, as in the cases of 3-hydroxy-methylglutaryl-coA reductase (HMGCR), mevalonate kinase (MVK) and lanosterol demethylase (LDM) where positive FEBs were reported. These results demonstrated the potential of allantoin to alleviate age-related hypercholesterolaemia by upregulating AMPK and downregulating cholesterol biosynthesis via the mevalonate pathway and Bloch pathway.2,5-Furandicarboxylic acid (FDCA) is a promising bio-based building block as a green alternative to petroleum-based terephthalate in polymer production. Most of FDCA is produced by the oxidation of 5-hydroxymethylfurfural (HMF), which is derived from hexose. Although the chemical conversion is widely applied, the biocatalytic conversion is expected due to the relatively mild condition and fewer toxic chemicals consumption. However, it's difficult to catalyze the conversion of HMF to FDCA by a single enzyme. Here, a newly enzymatic cascade reaction process was introduced with a yield of 94.0% by the combination of 5-hydroxymethylfurfural oxidase (HMFO) and lipase. Briefly, a flavine adenosine dinucleotide independent (FAD-independent) HMFO of Methylovorus sp. MP688 was used to convert HMF to 2,5-diformylfuran (DFF) and 5-formylfuroic acid (FFA), which consecutively transformed to FDCA by a lipase Novozym 435. To facilitate the purification, a coupled alkali precipitation was developed to recover FDCA from organic solvent with an improved purity from 84.4 to 99.0% and recovery of 78.1%. This work will help to construct the green biorefinery route for the bulk FDCA from biomass by enzymes.The aim of this study was to improve the acid tolerance of Lactobacillus acidophilus by combining atmospheric and room temperature plasma (ARTP) mutation with adaptive laboratory evolution (ALE). To achieve a high mutation efficiency, 60 s was determined as the ideal exposure time for ARTP mutation of L. acidophilus with a survival rate of 5.91%. click here The ARTP-ALE mutant strain LAartp-ale2 displayed increased lactic acid stress tolerance with survival rates of 75.67% and 25.78% when cultured in pH 3.0 and 2.5, respectively, for 3 h. Physiological analysis revealed that the ARTP-ALE mutant exhibited a lower inner membrane permeability than that of the parental strain during acid stress. Furthermore, the mutant LAartp-ale2 produced more biofilm in response to lactic acid-induced acid stress and showed an increased hydrophobicity (87.2%) when compared to the parent strain (76.2%) at pH 2.5. LAartp-ale2 exhibited a higher unsaturated fatty acid (UFA) to saturated fatty acid (SFA) ratio that affected the physical state of the cell membrane for increased survival in pH 3.0 and 2.5. The mutation with ARTP coupled with ALE in the present study proved to be effective in enhancing the acid tolerance of L. acidophilus for potential industrial use.BACKGROUND Research shows that loss of control (LOC) eating impacts weight outcomes following bariatric surgery, but mechanisms explaining the development and/or maintenance of post-surgical LOC eating remain unclear. Ecological momentary assessment (EMA) research among eating disorder populations has demonstrated prospective relationships between negative affect (NA) and LOC eating; however, this momentary effect has not been examined among bariatric surgery patients. Thus, this study used EMA data to examine momentary relationships between NA and LOC eating among pre- and post-bariatric surgery patients. METHODS Fourteen pre- and 17 post-RYGB patients completed 2 weeks of EMA data collection. Participants responded to seven signals daily wherein they rated their mood and severity of LOC eating. RESULTS Higher momentary NA predicted more severe LOC eating for all participants. Group had a moderating effect, demonstrating that the association between NA and LOC eating was stronger among the post-surgery group. Percent total body weight loss (%TBWL) had a moderating effect within the post-surgery group, demonstrating that the relationship between NA and LOC eating was stronger for those who experienced less weight loss. Finally, between-subjects analyses revealed that, for individuals with lower %TBWL, lower overall NA and higher overall positive affect (PA) were related to greater LOC eating. CONCLUSIONS This research demonstrates that affect influences the effect of LOC eating on weight loss following bariatric surgery. While further work is needed to extend these preliminary findings, this research suggests that affective experience might become an important target in the assessment and treatment of LOC eating among bariatric patients.BACKGROUND India is the largest hub for bariatric and metabolic surgery in Asia. OSSI is committed to improve the quality of care and set the standards for its practice in India. METHODS The first draft of OSSI guidelines was prepared by the secretary, Dr. Praveen Raj under the guidance of current President, Dr. Arun Prasad. All executive council members were given voting privileges, and the proposed guidelines were circulated on email for approval of the executive council. Guidelines were finalized after 100% agreement from all voting members and were also circulated among all OSSI members for their suggestions. RESULTS OSSI upholds the BMI criteria for bariatric and metabolic surgery of 2011 IFSO-APC guidelines. In addition to this, we recognize that waist circumference of ≥ 80 cm in females and ≥ 90 cm in males along with obesity related co-morbidities may be considered for surgery. In addition to standard procedures as recommended by IFSO, OSSI acknowledges the additional procedures, and a review of literature for these procedures is presented in the discussion.
