Comparison of the effects of liraglutide and sibutramine in obese patients

Background: Obesity is a global noncommunicable pandemic. The low effectiveness of treating obesity is associated with the difficulty of maintaining weight loss due to the reaction of the appetite regulation system. Drugs with central mechanisms of action can help overcome this problem.Aim: The aim of our study was to compare the effects of liraglutide and sibutramine (Reduxin) on the dynamics of weight and cardiometabolic parameters in obese patients without cardiovascular diseases.Materials and methods: We estimated the dynamics of the main metabolic parameters (BMI, glucose, lipid metabolism, blood pressure), the level of hormones involved in the regulation of fat metabolism (leptin, adiponectin, insulin), the ­HOMA-IR index, markers of oxidative stress and inflammation during therapy with liraglutide in comparison with reduxin for 6 months in obese patients.Results: 64 obese patients were included in the study: 25 patients — in the “Liraglutide” group, 39 patients — in the “Sibutramine” group in accordance with the declared inclusion / exclusion criteria. The included patients were young, average body mass index (BMI) (37.92 ± 5.45 kg / m2), average glycemic level was 5.47 ± 0.81 mmol /l, HOMA-IR was 6.01 ± 4.25, blood pressure was at inclusion was within the normal range, but 21.8% of patients received antihypertensive therapy.Both treatment options provided a comparable decrease in body weight (-10.28% vs -9.47%, p = 0.13)., Leptin level (-32.12% vs -41.77%, p = 0.77) and myeloperoxidase (-33.33% vs -19.91%, p = 0.2). The blood pressure level did not change significantly on liraglutide, while on reduxin the level of diastolic blood pressure (dBP) increased significantly (6.87%, p = 0.006). There was a more pronounced decrease in insulin levels compared to the baseline level (-46%, p = 0.005), as well as a decrease in the HOMA-IR index (-50.08, p = 0.005) on liraglutide therapy.An increase in adiponectin levels (+ 45.36% vs 14.01%, p = 0.0045) and a decrease in low density lipoprotein(LDL) cholesterol were significantly more pronounced on reduxin therapy (-15.03% vs -9.4%, p = 0.006).36% of the participants completed their participation in the study ahead of schedule due to the lack of effect in the form of weight loss in the «Liraglutide» group. Side effects in the “Liraglutide” group were observed in 16% of patients. 48% of patients took part in the study within 6 months. In the «Sibutramine» group 33.4% of patients completed the study ahead of schedule for reasons unrelated to the drug intake, the side effects were observed in 20.5% of patients. 46.1% of participants in the «Sibutramine» group received therapy for 6 months.Conclusions: This study confirms the previous findings that both liraglutide and reduxin therapy provide effective weight loss. We found a positive trend in markers of inflammation, atherogenesis and oxidative stress, and leptin levels. Liraglutide therapy was accompanied by a more pronounced effect on the state of carbohydrate metabolism, and reduxin therapy provided a more pronounced dynamics of lipid disorders and adiponexin. Both groups were characterized by a rather low adherence to therapy, but the incidence of side effects requiring stopping therapy was higher in the Sibutramine group

The polyacrylic acid/modified chitosan capsules with tunable release of small hydrophobic probe and drug

© 2015 Elsevier B.V. Nanocapsules (≤200. nm) with a protection effect toward small hydrophobic guests (p-nitrophenyl laurate and acetylsalicylic acid, aspirin) and a tunable sustained release behavior have been fabricated through the layer-by-layer deposition of polyacrylic acid and modified chitosan. Cationic surfactant, cetyltrimethylammonium bromide, was used to increase the affinity of polyelectrolyte to the substrate. The release profile was monitored through original protocol involving a fast cleavage of the substrate released and a spectrophotometric control of the product. The shell permeability of the capsules and hence their protective effect may be tuned through the variation of the number of layers deposited, the sonication, and the adjustment of solution pH. Importantly, the dispersed loads serving as a template for the capsule fabrication may control their properties, including shell permeability

Behavioural impairments in mice of a novel FUS transgenic line recapitulate features of frontotemporal lobar degeneration.

Multiple clinical and experimental evidence suggest that ALS and FTLD are members of a disease continuum. Pathological FUS inclusions have been observed in subsets of patients with these diseases but their anatomical distribution is different for two diseases. These structures are present in motor neurons in ALS cases but in cortical neurons in FTLD cases. Expression of a C‐terminally truncated form of human FUS causes an early onset and progressive motor neuron pathology in transgenic mice but only when these neurons express a certain level of this protein. Severe motor dysfunction and early lethality of mice with expression above this level prevent their use for studies of FTLD‐related pathology caused by expression of this form of FUS. In the present study we used another line of mice expressing the same protein but not developing any signs of motor system dysfunction due to substantially lower level of transgene expression in motor neurons. In a set of tests 5‐month old mice displayed certain behavioural abnormalities, including increased impulsivity, decreased anxiety and compromised social interaction, that recapitulate behaviour characteristics typically seen in FTLD patients

Novel Biodegradable Polymeric Microparticles Facilitate Scarless Wound Healing by Promoting Re-epithelialization and Inhibiting Fibrosis

Despite decades of research, the goal of achieving scarless wound healing remains elusive. One of the approaches, treatment with polymeric microcarriers, was shown to promote tissue regeneration in various in vitro models of wound healing. The in vivo effects of such an approach are attributed to transferred cells with polymeric microparticles functioning merely as inert scaffolds. We aimed to establish a bioactive biopolymer carrier that would promote would healing and inhibit scar formation in the murine model of deep skin wounds. Here we characterize two candidate types of microparticles based on fibroin/gelatin or spidroin and show that both types increase re-epithelialization rate and inhibit scar formation during skin wound healing. Interestingly, the effects of these microparticles on inflammatory gene expression and cytokine production by macrophages, fibroblasts, and keratinocytes are distinct. Both types of microparticles, as well as their soluble derivatives, fibroin and spidroin, significantly reduced the expression of profibrotic factors Fgf2 and Ctgf in mouse embryonic fibroblasts. However, only fibroin/gelatin microparticles induced transient inflammatory gene expression and cytokine production leading to an influx of inflammatory Ly6C+ myeloid cells to the injection site. The ability of microparticle carriers of equal proregenerative potential to induce inflammatory response may allow their subsequent adaptation to treatment of wounds with different bioburden and fibrotic content

Complete Genome Sequence of the N2-Fixing Broad Host Range Endophyte Klebsiella pneumoniae 342 and Virulence Predictions Verified in Mice

We report here the sequencing and analysis of the genome of the nitrogen-fixing endophyte, Klebsiella pneumoniae 342. Although K. pneumoniae 342 is a member of the enteric bacteria, it serves as a model for studies of endophytic, plant-bacterial associations due to its efficient colonization of plant tissues (including maize and wheat, two of the most important crops in the world), while maintaining a mutualistic relationship that encompasses supplying organic nitrogen to the host plant. Genomic analysis examined K. pneumoniae 342 for the presence of previously identified genes from other bacteria involved in colonization of, or growth in, plants. From this set, approximately one-third were identified in K. pneumoniae 342, suggesting additional factors most likely contribute to its endophytic lifestyle. Comparative genome analyses were used to provide new insights into this question. Results included the identification of metabolic pathways and other features devoted to processing plant-derived cellulosic and aromatic compounds, and a robust complement of transport genes (15.4%), one of the highest percentages in bacterial genomes sequenced. Although virulence and antibiotic resistance genes were predicted, experiments conducted using mouse models showed pathogenicity to be attenuated in this strain. Comparative genomic analyses with the presumed human pathogen K. pneumoniae MGH78578 revealed that MGH78578 apparently cannot fix nitrogen, and the distribution of genes essential to surface attachment, secretion, transport, and regulation and signaling varied between each genome, which may indicate critical divergences between the strains that influence their preferred host ranges and lifestyles (endophytic plant associations for K. pneumoniae 342 and presumably human pathogenesis for MGH78578). Little genome information is available concerning endophytic bacteria. The K. pneumoniae 342 genome will drive new research into this less-understood, but important category of bacterial-plant host relationships, which could ultimately enhance growth and nutrition of important agricultural crops and development of plant-derived products and biofuels

Synthesis and properties of the heterospin (S1 = S2 = 1/2) radical-ion salt bis(mesitylene)molybdenum(I) [1,2,5]thiadiazolo[3,4-c][1,2,5]thiadiazolidyl

Mendeleev, Tomsk State University, for support of his work.Low-temperature interaction of [1,2,5]thiadiazolo[3,4-c][1,2,5]thiadiazole (1) with MoMes2 (Mes = mesitylene / 1,3,5-trimethylbenzene) in tetrahydrofuran gave the heterospin (S1 = S2 = 1/2) radical-ion salt [MoMes2]+[1]– (2) whose structure was confirmed by single-crystal X-ray diffraction (XRD). The structure revealed alternating layers of the cations and anions with the Mes ligands perpendicular, and the anions tilted by 45°, to the layer plane. At 300 K the effective magnetic moment of 2 is equal to 2.40 μB (theoretically expected 2.45 μB) and monotonically decreases with lowering of the temperature. In the temperature range 2−300 K, the molar magnetic susceptibility of 2 is well-described by the Curie-Weiss law with parameters C and θ equal to 0.78 cm3⋅K⋅mol–1 and −31.2 K, respectively. Overall, the magnetic behavior of 2 is similar to that of [CrTol2]+[1]– and [CrCp*2]+[1]–, i.e. changing the cation [MAr2]+ 3d atom M = Cr (Z = 24) with weak spin-orbit coupling (SOC) to a 4d atom M = Mo (Z = 42) with stronger SOC does not affect macroscopic magnetic properties of the salts. For the XRD structure of salt 2, parameters of the Heisenberg spin-Hamiltonian were calculated using the broken-symmetry DFT and CASSCF approaches, and the complex 3D magnetic structure with both the ferromagnetic (FM) and antiferromagnetic (AF) exchange interactions was revealed with the latter as dominating. Salt 2 is thermally unstable and slowly loses the Mes ligands upon storage at ambient temperature. Under the same reaction conditions, interaction of 1 with MoTol2 (Tol = toluene) proceeded with partial loss of the Tol ligands to afford diamagnetic product.PostprintPostprintPeer reviewe
