In this study, a large volume sample stacking (LVSS) with polarity switching (PS) and cyclodextrin electrokinetic chromatography (CDEKC) method has been developed for the simultaneous separation and determination of 8 preservatives methylparaben (MP), ethylparaben (EP), propylparaben (PP), butylparaben (BP), isobutylparaben (IBP), sorbic acid (SA), benzoic acid (BA), p-hydroxybenzoic acid (PHBA) in pharmaceuticals. The effects of some typical parameters such as sample volume, applied voltage, composition and pH of the running buffer and organic modifier concentration were examined and optimized. Moreover, the impact of type and concentration of cyclodextrin as electrolyte modifiers was also investigated. The detection limits of analytes for the elaborated LVSS-PS-CDEKC method were found to be in 0.8-5 ng mL-1 range, which were around 500 times lower than normal CDEKC without preconcentration technique. All analytes were completely resolved in less than 11 min in an uncoated fused-silica capillary of 75 μm internal diameter (I.D) x 50 cm length. The electrophoretic separation was performed in a 2 mM α-cyclodextrin and 25 mM tetraborate system (pH = 9.3) with an applied voltage of 25 kV. The established method was validated and confirmed to be applicable for the determination of the preservatives in a quality control of pharmaceuticals. INTRODUCTION Open reduction with internal fixation (ORIF) and intramedullary nailing (IMN) have similar union rates for treating humerus shaft fractures, but IMN leads to increased incidence of shoulder impingement and reoperation. The difference in 30-day readmission rate and length of stay (LOS) between these procedures is unknown. The objective of the study was to compare 30-day unplanned readmissions and length of stay between humeral shaft fractures fixed with either ORIF or IMN. METHODS The nationwide readmissions database (NRD) was queried for patients with humeral shaft fractures treated with ORIF or IMN between 2015-2016. IMN cases were propensity matched to ORIF cases based on demographic and co-morbid variables. Multivariable logistic regression determined if treatment modality was an independent risk factor for 30-day readmission or length of stay >3 days. RESULTS There were 406 patients treated with IMN matched to 406 patients treated with ORIF. The 30-day readmission rate was 6.4% for IMN and 4.9% for ORIF (p = 0.45), and the median LOS was 3 days for each group (p = 0.45). Congestive heart failure (CHF)(OR=2.7, p = 0.04), depression (OR=3.3, p = 0.0008), and electrolyte abnormality (OR=3.6, p = 0.0003) were independent risk factors for readmission. Older age (OR=1.02, p = 0.03), CHF (OR=2.4, p = 0.03), electrolyte abnormality (OR=2.6, p = 0.0001), obesity (OR=2.8, p3 days. CONCLUSION Comorbid conditions are risk factors for 30-day readmission and increased LOS. Comorbidity, discharge disposition, and open fractures are risk factors for increased LOS. Treating humeral shaft fractures with either ORIF or IMN did not affect readmission or length of stay. BACKGROUND In recent years, Minimally Invasive Plate Osteosynthesis (MIPO) has been gaining popularity in the treatment of distal tibia fractures, because it is a minimally invasive surgical procedure, thus it limits the soft-tissues damage. This prospective randomized study aims to assess the impact of lag screw in the healing time of distal tibia fractures treated with MIPO technique, in a six-month follow-up. METHODS Patients between 20 and 70 years of age with distal tibial fracture, type 43-A according to AO/OTA classification system. All the patients were randomized into two groups, to receive MIPO without lag screw (Group-A) or MIPO with percutaneous lag screw (Group-B). BLU-554 ic50 Patients were followed clinically and radiographically at 3, 6, 12 and 24 weeks postoperatively. The main outcome measure was the time needed to achieve the painless full weight-bearing (FWB) after surgery. Unpaired t-test after ANOVA (analysis of variance) was performed to assess AOFAS score differences between the 2 groups at each follow-up. Pearson correlation test also was performed. The tests were two-tailed with a confidence level of 5%. RESULTS 42 patients (24 male and 18 female, mean age 49.54 years old, range 25-80) were recruited. A significant shorter mean time until painless FWB (p = 0.016) was observed in Group-B (11.22 ± 3.06 weeks) compared with Group-A (13.48 ± 2.42 weeks) (Table 2). The mean AOFAS score was comparable in patients treated with (Group-B) and without lag screw (Group-A) at all follow-ups. CONCLUSIONS This prospective randomized clinical study has shown that the use of lag screw in distal tibia fractures treated with MIPO technique speeds the fracture healing, thus shortening the time needed to achieve FWB. Waste biomass of two major milk weeds was separately given combination of chemical-mechanical treatments in order to expose natural cellulosic micro and nano-fibrillated structures (MFCs and NFCs). Compositional and FTIR analysis were initially used to confirm the removal of impurities. WA-XRD and FESEM analysis of MFCs further revealed presence of highly crystalline, fine-shaped materials that resemble carbonaceous structures. HR-TEM analysis further exposed morphology of the two nanofibrils possessing a well entangled network (diameter ≤80 nm) comprising coil shaped fine spots of size up to 80 nm-220 nm. Morphology even got clearer when STEM and EDX mapping of the NFCs assured that observed fine-spots are integral and possibly due to certain biosynthetic process. Presence of calcium elements in two types of NFCs provided important evidence of exposure of nanocellulose-xyloglucan-pectin configuration responsible for coil-shaped fine-spots resembling "biomechanical hot spots". Considering the advancements in the applications of biopolymers such as Chitosan due to its biocompatibility, biodegradability and non-toxic properties, five different Chitosan cinnamaldehyde Schiff bases (Chi-Cn1-5) using chitosan and cinnamaldehyde as monomer units were synthesized by varying the degree of substitution. Further, anti-corrosion property of all these biopolymers against corrosion of mild steel was studied in 0.5 M H2SO4 by gravimetric and electrochemical methods. Scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS), atomic force microscopy (AFM), scanning electrochemical microscopy (SECM) and X-ray photoelectron spectroscopy (XPS) were utilized to affirm the adsorption of studied biopolymers at the metal/electrolyte interface by inhibiting mild steel (MS) corrosion. The shift ( less then 85 mV) in the value of corrosion potential by the presence of biopolymers affirmed their mixed-type nature of inhibition. The results depicted that Chi-Cn5 performs best against corrosion of mild steel in acid medium among all other biopolymers due to its maximum degree of substitution.
