OBJECTIVES To investigate the viscosity values of mixtures of hyaluronic acids with different molecular weights and the effects of these mixtures on the enzymatic activities of lysozyme and peroxidase. MATERIALS AND METHODS Mixtures of high molecular weight (1 or 2 MDa) and low molecular weight (10 or 100 kDa) hyaluronic acids at different concentrations were used for viscosity measurements. Hyaluronic acid mixtures showing viscosity values similar to those of human whole saliva were used for enzyme experiments in solution and on hydroxyapatite surface. Hen egg-white lysozyme, bovine lactoperoxidase, and human whole saliva were used as enzyme sources. Lysozyme activity was measured by hydrolysis of fluorescein-labeled Micrococcus lysodeikticus. Peroxidase activity was measured by oxidation of fluorogenic 2',7'-dichlorofluorescein to fluorescing 2',7'-dichlorofluorescein. RESULTS The mixtures of 1 MDa (0.5 mg/mL) or 2 MDa (0.2 mg/mL) hyaluronic acid with 10 kDa (2.0 mg/mL) or 100 kDa (0.1 mg/mL) hyaluronic acid had viscosity values similar to those of human whole saliva at shear rates, reflecting normal oral functions. Compared with single molecular weight hyaluronic acids, these mixtures showed viscosity values more similar to those of human whole saliva. The mixtures inhibited lysozyme and peroxidase activities on the hydroxyapatite surfaces; however, the degree of inhibition did not differ from that of hyaluronic acid of 1 or 2 MDa only. CONCLUSIONS Compared with single molecular weight hyaluronic acids, hyaluronic acid mixtures showed viscosity values more similar to those of human whole saliva, without additional inhibitory effects on lysozyme and peroxidase activities. CLINICAL RELEVANCE Hyaluronic acid mixtures offer distinct advantages for the development of saliva substitutes.BACKGROUND Recalcitrant nature is a major constraint for the in vitro regeneration and genetic transformation of leguminous species members. Therefore, an improved genetic transformation in horse gram has been developed via in planta method, in which Agrobacterium strain harboring binary vector pCAMBIA2301 was used for the transformation. Several factors affecting in planta transformations were put forth viz. Agrobacterium cell density, co-cultivation, and sonication combined with vacuum infiltration duration which were optimized. RESULTS Germinated seeds were sonicated and vacuum infiltrated with different densities of Agrobacterium culture and co-cultivated in half-strength MS medium with 100 μM of acetosyringone for 48 h. Seedlings were washed with cefotaxime and sowed in vermiculite soil for maturation. T1 plants were subjected to histochemical and molecular analysis to ensure transformation efficiency. Among various combinations analyzed, maximum transformation efficiency (20.8%) was attained with seeds of 5 min sonication combined with vacuum infiltration with 0.6 optical density of Agrobacterium culture. CONCLUSIONS It concludes that a different Agrobacterium cell density with sonication combined with vacuum infiltration has improved transgenic efficiency in horse gram plants. This simple and efficient method is feasible for the stable expression of foreign genes that could be beneficial for future food security.Lipases CAL-B, TLL, and RML were used in the synthesis of free fatty acids of grape seed oil as heterogeneous substrate. The best enzyme was used to optimize the reaction variables temperature, enzyme content, and molar ratio of wateroil in batch reactions using experimental planning. The ideal conditions to produce free fatty acids using pure RML were 45 °C, 121 substrate molar ratio, and 15% enzyme, resulting in 66% of oil hydrolysis and a productivity of 0.54 mol L-1 min-1 in 4 h of reaction at 180 rpm. Repeated batches of reaction were performed testing the operational stability of RML, results showing that this enzyme could be used for at least 20 cycles keeping more than 80% of its initial activity, suggesting its potential use in industrial processes. The synthesis of free fatty acids was then evaluated in continuous reactions using packed-bed reactor (PBR). The highest productivity in the continuous process was 6.85 mol L-1 min-1, using only RML, showing an operational stability higher than 80% of its initial conversion capacity after 11 days of operation, at a flow rate of 0.13 mL min-1 at 45 °C. We evaluated the use of this hydrolyzed oil as substrate for lactone bioproduction using Galactomyces geotrichum UFMG-CM-Y3276, G. geotrichum UFMG-CM-Y3558, and Geotrichum klebahnii UFMG-CM-Y3014 screened for their oil-hydrolysis ability. Volatile compounds were qualitatively identified in GC-MS as γ-octalactone and γ-nonalactone.A composite was synthesized from two-dimensional molybdenum disulfide (MoS2) nanosheets and hypercrosslinked polymers (HCP), and the composite was characterized by infrared spectroscopy, scanning electron microscopy, and specific surface area. The fluffy and porous structure and multiple adsorption sites (π-interaction, static electricity, hydrogen bonding) make it ideal for use as an adsorbent. A pipette tip solid-phase extraction with the composite as the adsorbent combined with HPLC-FLD was developed to determine trace amounts of polycyclic aromatic hydrocarbons (phenanthrene, anthracene, fluoranthene, pyrene, benzo(α)anthracene) in environmental water. Under optimal extraction conditions, the method has a wide linear range (0.5-100 ng mL-1) and low limit of detection (0.024-0.099 ng mL-1), and the recoveries of PAHs from spiked environmental water were 73.8% to 123.6% (relative standard deviation ≤ 6.7%, n = 3). Graphical abstract Schematic representation of a three-dimensional molybdenum disulfide-ethylenediamine-hypercrosslinked polymer composite (MoS2-EDA-HCP) using pipette tip solid-phase extraction adsorbent for extracting trace levels of polycyclic aromatic hydrocarbons (PAHs) prior to HPLC-FLD. HCP, hypercrosslinked polymer; MoS2, molybdenum disulfide; EDA, ethylenediamine.Biosorption of Cr(VI) on sulfuric and phosphoric acid-treated Datura stramonium fruit was investigated in batch mode. The various parameters that influence the biosorption process such as Cr(VI) initial concentration, biosorbent dosage, contact time, temperature, and pH value were optimized. Both linear and non-linear regression analysis of isotherm data suggest that Langmuir isotherm model mimics the behavior of Cr(VI) ion biosorption onto Datura stramonium fruit biosorbent. The maximum Cr(VI) ions adsorption capacity of 138.074 mg/g at pH 2 is achieved with phosphoric acid treated Datura stramonium (PDSF). The kinetics of adsorption process is well described by pseudo-second-order model with high R2 and low χ2 value. The estimated activation energy of less then  8 kJ/mol obtained for both raw and chemically modified adsorbents suggests that the adsorption occurs mainly via physisorption. Besides, thermodynamic results reveal that biosorption of Cr(VI) on both treated and untreated Datura stramonium was endothermic, spontaneous, and randomness in nature.BACKGROUND Cerebral proliferative angiopathy (CPA) is a rare subset of arteriovenous malformations (AVM). Selleckchem Napabucasin It has unique clinical presentation, angiographic characteristics, and pathophysiology which often brings challenges for the treatment. We aimed to define its epidemiology, pathophysiology are unknown, and best management strategies. METHODS A systematic review was conducted according to the PRISMA guidelines. MEDLINE was searched for articles regarding CPA. Extracted data included epidemiological, clinical, and angiographical characteristics, treatment, and outcomes. Treatment was classified as conservative, radiosurgery, endovascular, decompression, and indirect vascularization. A meta-analytical approach was employed for description of the data as study-size adjusted percentages or weighted means, as appropriate. RESULTS Thirty-three studies were analyzed, rendering a total 95 cases-half of which came from a single study. Patients were predominantly young (mean 23 years old) and female (60.0%) presenting with headaches (44.9%), seizures (37.1%), or transient ischemic attacks (33.7%). Hemorrhage was present in 18.0%, but rebleeding rates were as high as 67%. The majority of nidus were > 6 cm (52.5%) with hemispheric extension (73.0%). Capillary angioectatic appearance (85.7%), transdural supply (62.5%), and deep venous drainage (73.0%) were also frequent features. Most patients were treated conservatively (54.4%), followed by endovascular (34.2%). Indirect vascularization and radiosurgery were attempted in five and two patients, respectively. Mean follow-up was 110.8 patient-years. Neurological status improved in 50.7%, remained stable in 40.2%, and worsened in 9.0%. CONCLUSIONS Conservative and endovascular treatments seem adequate interventions, despite limited evidence. Complementary techniques can be used in patients throughout disease history, according to symptom-based, individualized approach. More studies are required for choosing interventions based on reliable long-term results.AIMS This study aimed to compare the efficacy and safety of generic exenatide with branded exenatide Byetta® in Chinese patients with type 2 diabetes mellitus (T2DM) inadequately controlled on monotherapy or combination therapy of metformin and insulin secretagogues. METHODS A multicenter, randomized, controlled, non-inferiority trial was performed. A total of 240 patients with T2DM and glycated hemoglobin (HbA1c) ≥ 7% (53 mmol/mol) to ≤ 9.0% (75 mmol/mol) on monotherapy or combination therapy of metformin and insulin secretagogues for at least 3 months were randomized into generic exenatide or branded exenatide groups with a 11 ratio for 16 weeks of treatment. The primary endpoint was the change in HbA1c levels from baseline at week 16, with a non-inferiority margin of - 0.35% (- 3.83 mmol/mol) (lower bound of one-sided 95% confidence interval (CI) > - 0.35% (- 3.83 mmol/mol)). Secondary endpoints included the proportion of participants achieving HbA1c  0.05). CONCLUSIONS In patients with T2DM inadequately controlled on monotherapy or combination therapy of metformin and insulin secretagogues, add-on treatment with generic exenatide demonstrated non-inferiority to branded exenatide in terms of improvements in HbA1c after 16 weeks of treatment. Furthermore, the two drugs were also similar for other efficacy endpoints and safety profile.

METHODS Data from an observational registry including patients admitted with acute cerebral ischemia while taking oral Factor Xa inhibitors for atrial fibrillation between April 2016 and December 2018 were investigated. The dose regimen of the Xa inhibitor was classified as "appropriate", "underdosed" and "overdosed" in conformity with the European Medicines Agency labelling. The effect of underdosing on the functional factor Xa plasma level on admission, the clinical stroke severity and the functional outcome after 3 months were investigated. RESULTS 254 patients with cerebral ischemia while on Factor Xa inhibitors were included. The dose regimen of the Factor Xa inhibitor was appropriate in 166 patients (65%), underdosed in 67 patients (26%) and overdosed in 21 patients (8%). Underdosing was associated with female sex, diabetes mellitus and higher CHA2DS2-Vasc scores.
