Various concentrations (0.01, 0.03 and 0.05 wt ratios) of graphene oxide (GO) nanosheets were doped into magnesium oxide (MgO) nanostructures using chemical precipitation technique. The objective was to study the effect of GO dopant concentrations on the catalytic and antibacterial behavior of fixed amount of MgO. XRD technique revealed cubic phase of MgO, while its crystalline nature was confirmed through SAED profiles. Functional groups presence and Mg-O (443 cm−1) in fingerprint region was evident with FTIR spectroscopy. Optical properties were recorded via UV–visible spectroscopy with redshift pointing to a decrease in band gap energy from 5.0 to 4.8 eV upon doping. Electron–hole recombination behavior was examined through photoluminescence (PL) spectroscopy. Raman spectra exhibited D band (1338 cm−1) and G band (1598 cm−1) evident to GO doping. Formation of nanostructure with cubic and hexagon morphology was confirmed with TEM, whereas interlayer average d-spacing of 0.23 nm was assessed using HR-TEM. Dopants existence and evaluation of elemental constitution Mg, O were corroborated using EDS technique. Catalytic activity against methyl blue ciprofloxacin (MBCF) was significantly reduced (45%) for higher GO dopant concentration (0.05), whereas bactericidal activity of MgO against E. coli was improved significantly (4.85 mm inhibition zone) upon doping with higher concentration (0.05) of GO, owing to the formation of nanorods.

Novel tantalum (Ta) and chitosan (CS)-doped CuO nanorods (NRs) were synthesized using a single step co-precipitation route.

Abstract Objective: To determine the effectiveness of Mulligan mobilisation versus Cyriax approach in the management of patients with subacute lateral epicondylitis. Methods: The clinical trial was conducted at the District Headquarter Hospital, Bahawalnagar, Pakistan, from September to December 2018, and comprised lateral epicondylitis patients having symptoms for >2 weeks. The diagnosis was confirmed on the basis of physical tests and musculoskeletal ultrasound. The subjects were randomly allocated to two equal groups A and B. Group A received deep transverse friction and Mill’s manipulation according to Cyriax approach, while group B received Mulligan mobilisation with movement techniques. Patient-related tennis elbow evaluation index was used to collect data which was analysed using SPSS 20. Results: Of the 60 patients, there were 30(50%) in each of the two groups. The overall mean age was 35.27±7.30 years, and 38(63.3%) participants were male.  After 4 weeks of treatment sessions, both groups showed significant improvements (p<0.05) in pain and functional disability scores. Group A showed significantly more improvement (p<0.05) in pain subscale scores compared to group B, while group B showed significant improvement (p<0.05) in functional disability subscale scores compared to group A. There was no significant difference (p>0.05) between the groups on total the patient-related tennis elbow evaluation index score. Conclusion: Both Mulligan mobilisation with movement and Cyriax approach decreased pain and improved functional status in lateral epicondylitis patients.
