Decompression is one of the most common interventions in spinal surgery. IMT1B solubility dmso Obesity has become an increasing issue in surgical patients. Therefore, the aim of this study was to analyze the clinical outcome following lumbar microsurgical decompression in correlation with the patient's body mass index (BMI).

A toal of 744 patients with spinal claudication that were seen at two specialized spine centers were included in this study. All patients underwent a bilateral microsurgical decompression in over-the-top technique. Patients were allocated in 4 groups based in their BMI category 18.5-24.9 (n = 204), 25.0-29.9 (n = 318), 30.0-34.9 (n = 164) and ≥ 35 (n = 58). Clinical outcome data were recorded at baseline as well as 3, 12 and 24months thereafter within a prospective study framework. The minimum follow-up was 12months. For statistical analysis, data were adjusted for age, length of surgery and ASA and were analyzed by generalized linear gamma-based models.

Postoperative changes in all outcome parameters were clearly dependent on BMI. Patients with higher BMI were characterized by inferior baseline values for VAS Back (p < 0.05). Over the follow-up period, the groups with BMI 30-34.9 and BMI ≥ 35 benefitted significantly less from the surgery than the two slimmer groups (p < 0.05).

The data obtained from this large, homogenous cohort demonstrate that the quality of life improved substantially in all patients that were treated microsurgically for spinal stenosis. However, a BMI ≥ 30 may be considered as a negative predictor for a significantly inferior clinical outcome.

To explore 3D hip orientation in standing position in subjects with adult spinal deformity (ASD) presenting with different levels of compensatory mechanisms.

Subjects with ASD (n = 159) and controls (n = 68) underwent full-body biplanar X-rays with the calculation of 3D spinopelvic, postural and hip parameters. ASD subjects were grouped as ASD with knee flexion (ASD-KF) if they compensated by flexing their knees (knee flexion ≥ 5°), and ASD with knee extension (ASD-KE) otherwise (knee flexion < 5°). Spinopelvic, postural and hip parameters were compared between the three groups. Univariate and multivariate analyses were then computed between spinopelvic and hip parameters.

ASD-KF had higher SVA (67 ± 66mm vs. 2 ± 33mm and 11 ± 21mm), PT (27 ± 14° vs. 18 ± 9° and 11 ± 7°) and PI-LL mismatch (20 ± 26° vs - 1 ± 18° and - 13 ± 10°) when compared to ASD-KE and controls (all p < 0.05). ASD-KF also had a more tilted (34 ± 11° vs. 28 ± 9° and 26 ± 7°), anteverted (24 ± 6° vs. 20 ± 5° and 18 ± 4°) and abduunderlying mechanism could be potentially involved in the hip-spine syndrome.Aromatic heterocyclic compounds are commonly used in pharmaceutical and agrochemical products. The usage has been also extended in the production of corrosion inhibitors and electronic, opto-electronic, and NLO devices. The four regioisomers of the aromatic heterocyclic molecule, tetrakis(4-pyridyl)cyclobutane (tpcb), were optimized, and their chemical, electronic, and biological properties were examined. The rctt and rtct isomers were isolated and further characterized by the infrared and Raman spectroscopic techniques, and their vibrational modes with attention on important functional groups were discussed. The theoretical vibrational data obtained by DFT/B3LYP/6-311++G(d,p) were in very good agreement with the experimental ones. The occupancy, bond polarization, hybridization of the N-C bond, bonding characteristics between the pyridyl carbon and cyclobutane moiety, and distribution of electron density for the four tpcb isomers have been explored through NBO analysis. The inversion barrier of the cyclobutane moiety was obtained based on the optimized structures of the planar and puckered configurations of the isomers. The rccc isomer exhibited the least electrophilic character compared to the other tpcb isomers. The chemical significance of tpcb has been further explained by the wave function analyses. Molecular docking results revealed that the tpcb ligand would possess a potential anti-viral and anti-bacterial activity via a membrane-permeable mechanism.Overproduction of free radicals in the body may result in oxidative stress, which plays an active role in the development of various health disorders. Consequently, the development of efficient free radical scavengers and evaluation of their antioxidant properties is a research area of interest. In the present research, computational quantum chemical approach based on the density functional theory (DFT) method was employed to elucidate the free radical scavenge of chalcone derivatives via thermodynamic studies. New set of chalcone antioxidants were designed. Their reactivity towards hydroperoxyl (HOO·) and methyl peroxyl (CH3OO·) radicals were investigated through systematic study of their mechanism of free radical scavenge. Various reaction enthalpies and Gibbs free energy that characterize the various steps in these mechanisms were computed in the gas phase and aqueous solution, in order to identify the main channels of reaction. Results in the gas phase indicate that hydrogen atom transfer (HAT) and sequential proton loss electron transfer (SPLET) mechanisms represent the most plausible reaction pathways, while single electron transfer followed by proton transfer (SET-PT) mechanism was thermodynamically unfeasible. However, these mechanisms were thermodynamically favoured in aqueous solution. Also, these chalcone derivatives were observed to be more effective in scavenging HOO· than CH3OO· radicals in both phases. Based on the exergonicity of the obtained results, the molecule MCHM 17 ((E)-1-(3-bromo-5-hydroxyphenyl)-3-(2,5-dihydroxyphenyl)prop-2-en-1-one) at the 5-OH site was found to exhibit the greatest potential to scavenge HOO· and CH3OO· radicals in both phases. This research is a gateway to the efficient exploitation of these compounds in pharmacy and food chemistry.
