Obesity is a major public health concern with an increasing prevalence. Recent studies suggest an influence of gastrointestinal microbiota on obesity. Consequently, microbiota restoration therapies are being considered as potential management. We present data on microbiome markers and the future of microbiota therapeutics for obesity.

We summarize the pathogenesis of obesity, relationship between gut microbiota and obesity, use of microbiota-based therapies. Data were gathered by a literature search of articles in PubMed from the date of inception till August 2020. Keywords used were 'gut microbiota,' 'gut microbiome,' 'microbiota,' 'microbiome,' 'obesity,' and 'obesity and fecal microbiota transplantation' as MeSH terms.

The direct relationship of gut microbiota in causing obesity needs exploration. Because of the scarcity of human studies, the utility of microbiota-based therapies as treatment remains uncertain and the use of microbiome restoration for obesity should be restricted to research settingsherapies for obese persons.
Swept source optical coherence tomography angiography (SS-OCT-A) choroidal vasculography (CVG) is an imaging method which allows the evaluation of deep choroid details, being a promising too in choroidal pathologies as polypoidal choroidal vasculopathy (PCV).

Cross-sectional study performed at FOSCAL International Clinic in Colombia. CVG features in patients with PCV were evaluated using SS-OCT CVG.

Twenty-two eyes of 21 patients were included. The mean age was 72.7±6.5years old (range 48.6-95.4years old). Twelve (57.1%) patients were male. The mean number of polyps detected by SS-OCT-A CVG before treatment with anti-VEGF therapy was 2.04±1.18, which decreased after treatment to 1.18±0.71. This result was statistically significant (p<0.05). All polypoidal lesions detected by B-scan were visualized using CVG. Polyp circularity and surrounding reflectivity indicated activity of disease.

En face SS-OCT-A CVG is an alternative tool to evaluate choroidal structure at different depths without a contrast dye, providing information for the diagnosis and follow-up of patients with PCV. This imaging modality do not pretend to replace gold standard tests in PCV as ICGA, but rather provides choroidal imaging features of PCV, when ICGA is not available.

The current study is the first to assess personality change desires with multiple methods in the same sample (N = 500 undergraduates). Findings with each method were compared to meta-analyses of other studies utilizing each respective method, and methods were then compared within-person to explore how the same person might provide different information about their desire to change their personality with each method. The findings of each method replicated the results of other studies using that method very closely. Some deviations from previous the studies in the prevalence of certain goals were likely due to goals being collected during a global pandemic. The three methods did not show a high degree of convergence. Only participants desiring to increase Extraversion in one method tended to express desires to increase Extraversion in the other two methods. The methodological differences between the methods impact the conclusions that can be drawn with each.We characterize the atomic processes that underlie forming, reset, and set in HfO2-based resistive random access memory (RRAM) cells through molecular dynamics (MD) simulations, using an extended charge equilibration method to describe external electric fields. By tracking the migration of oxygen ions and the change in coordination of Hf atoms in the dielectric, we characterize the formation and dissolution of conductive filaments (CFs) during the operation of the device with atomic detail. Simulations of the forming process show that the CFs form through an oxygen exchange mechanism, induced by a cascade of oxygen displacements from the oxide to the active electrode, as opposed to aggregation of pre-existing oxygen vacancies. However, the filament breakup is dominated by lateral, rather than vertical (along the filament), motion of vacancies. In addition, depending on the temperature of the system, the reset can be achieved through a redox effect (bipolar switch), where oxygen diffusion is governed by the applied bias, or by a thermochemical process (unipolar switch), where the diffusion is driven by temperature. Unlike forming and similar to reset, the set process involves lateral oxygen atoms as well. This is driven by field localization associated with conductive paths.Developing peptide tags that can bind target proteins covalently under mild conditions is of great importance for a myriad of applications, ranging from chemical biology to biotechnology. Here we report the development of a small covalent peptide tag system, termed as GB tags, that can covalently label the target protein with high specificity and high yield under oxidizing conditions. The GB tags consist of a pair of short peptides, GN and GC (GN contains 45 residues and GC contains 19 residues). GN and GC, which are split from a parent protein GB1, can undergo protein fragment reconstitution to reconstitute the folded structure of the parent protein spontaneously. The engineered cysteines in GN and GC can readily form a disulfide bond oxidized by air oxygen after protein reconstitution. Using thermally stable variants of GB1, we identified two pairs of GB tags that display improved thermodynamic stability and binding affinity. They can serve as efficient covalent peptide tags for various applications, including specific labeling of mammalian cell surface receptors. We anticipate that these new GB tags will find applications in biochemical labeling as well as biomaterials, such as protein hydrogels.Reliable antimicrobial susceptibility testing is essential in informing both clinical antibiotic therapy decisions and the development of new antibiotics. Mammalian cell culture media have been proposed as an alternative to bacteriological media, potentially representing some critical aspects of the infection environment more accurately. Here, we use a combination of NMR metabolomics and electron microscopy to investigate the response of Escherichia coli and Pseudomonas aeruginosa to growth in differing rich media to determine whether and how this determines metabolic strategies, the composition of the cell wall, and consequently susceptibility to membrane active antimicrobials including colistin and tobramycin. The NMR metabolomic approach is first validated by characterizing the expected E. coli acid stress response to fermentation and the accompanying changes in the cell wall composition, when cultured in glucose rich mammalian cell culture media. Glucose is not a major carbon source for P. aeruginosa but is associated with a response to osmotic stress and a modest increase in colistin tolerance. Growth of P. aeruginosa in a range of bacteriological media is supported by consumption of formate, an important electron donor in anaerobic respiration. In mammalian cell culture media, however, the overall metabolic strategy of P. aeruginosa is instead dependent on consumption of glutamine and lactate. Formate doping of mammalian cell culture media does not alter the overall metabolic strategy but is associated with polyamine catabolism, remodelling of both inner and outer membranes, and a modest sensitization of P. aeruginosa PAO1 to colistin. buy TPI-1 Further, in a panel of P. aeruginosa isolates an increase between 2- and 3-fold in sensitivity to tobramycin is achieved through doping with other organic acids, notably propionate which also similarly enhances the activity of colistin. Organic acids are therefore capable of nonspecifically influencing the potency of membrane active antimicrobials.Fourier transform infrared, pump-probe polarization anisotropy, and two-dimensional infrared spectroscopies were used to study the steady-state and time-dependent behavior of carbon dioxide dissolved in three different polymer systems. Gas reorientation dynamics in poly(methyl methacrylate), poly(methyl acrylate), and poly(dimethylsiloxane) were sensitive to the nature of chemical interactions between the gas and polymer, as well as whether the polymer was in a glassy or rubbery phase. The homogeneous dynamics experienced by the asymmetric stretching vibration were found to be fastest for rubbery polymers with weak, nonspecific gas-polymer interactions. Spectral diffusion was absent for the carbon dioxide vibrational mode in glassy poly(methyl methacrylate) but was activated for the chemically similar but rubbery poly(methyl acrylate). The vibrational dynamics are shown to have a direct correlation with the diffusivity of carbon dioxide through the polymer matrices.Metal-organic coordination structures at interfaces play an essential role in many biological and chemical systems. Understanding the molecular specificity, orientation, and spatial distribution of the coordination complexes at the nanometer scale is of great importance for effective molecular engineering of nanostructures and fabrication of functional devices with controllable properties. However, fundamental properties of such coordination systems are still rarely studied directly. In this work, we present a spectroscopic approach on the basis of tip-enhanced Raman spectroscopy (TERS) to investigate cobalt(II) tetraphenyl-porphyrine coordination species on the scale of a single molecule under ambient conditions. Coordination species anchored on gold surfaces modified with pyridine thiol self-assembled monolayers can be spectroscopically distinguished and mapped with ca. 2 nm resolution. In addition, in combination with density functional theory simulations, the adsorption configuration and molecular orientation of the coordination complexes are also revealed using TERS imaging.The nature of bonding in classical adducts and frustrated Lewis pairs (FLPs) of oxorhenium and nitridorhenium complexes with B(C6F5)3 was investigated computationally (B3PW91-D3). These studies have revealed that the primary noncovalent interaction (NCI) in the FLPs involves lone pair/π interactions between the terminal M≡X bond and the aromatic C6F5 ring in B(C6F5)3. Energy decomposition analyses on classical adducts and FLPs reveal that these species can be defined by the ratio (EOrb/ESteric) of covalent-to-noncovalent contributions to the total interaction energy, EInt. This type of analysis reveals that values for FLPs exist in a narrow range (1.2-2.5), with values for adducts significantly outside this range. The application of this method to other main-group combinations of Lewis acids and bases that have been shown to exhibit FLP reactivity yields similar results. These data suggest that similar NCIs are present in both transition-metal and main-group FLPs, especially where Lewis acids such as B(C6F5)3 are utilized.
