    93%; 95% CI 2.15-11.25%), followed by peroneal nerve palsy (2.25%; 95% CI 0.14-6.14%), fracture (0.56%; 95% CI 0-1.74%), and recurrent deformity (0.54%; 95% CI 0-1.74%). Furthermore, PFO was also associated with improved medial/lateral joint space ratio (MD 0.17; 95% CI 0.15-0.19).

    PFO yielded promising prospects in the management of medial compartment KOA, as shown by substantial improvements in clinical and radiological outcomes. However, considering the low quality of evidence, further studies with more diverse populations and higher quality of body evidence are required to confirm these findings.

The partial least squares discriminant analysis (PLS-DA) models were developed to discriminate the adulterated HFP from the authentic HFP, while the partial least squares regression (PLSR) models were employed to determine the contents of adulterants. In order to yield the best results, various spectra pretreatment methods and wavelength selection methods were carefully investigated. The models’ qualities were assessed by the self-consistency test, the independent test and the rigorous leave-one-out cross-validation test. The metrics for the PLS-DA discriminative model included error rate, true positive rate, true negative rate and F1 score, while the metrics for the PLSR quantitative model were determination coefficient, root mean square error and residual prediction deviation. Finally, very satisfying results were obtained, which indicate that our method is quite robust and applicable, and thus has great potential for rapid detection of adulteration in powder of many other herbal plants or functional foods.Mixed crystals of Dy3+/Sr2+ LaF3 and Dy3+/Ca2+ LaF3 were grown by Bridgman technique and their spectral properties were investigated. Spectra broadening and peak shifts were observed, indicating the co-doping of Sr2+/Ca2+ brings about a more disordered local symmetry of Dy3+, which makes both crystals favorable for tunable lasing action. Low-temperature high resolution excitation and emission spectra were carried out for exploring the types of luminescent center of Dy3+ in crystals. Room-temperature absorption and emission spectra, together with the fluorescence decay curves were studied in both crystals for estimating their potentials for yellow and MIR lasers. Under 450 nm excitation, the largest emission cross-sections at 571 nm of 1.51 × 10-21 cm2 for Dy3+/Sr2+ LaF3 crystal and 1.56 × 10-21 cm2 for Dy3+/Ca2+ LaF3 crystal, along with the lifetimes of Dy3+ 4F9/2 level as 0.983 ms for Dy3+/Sr2+ LaF3 crystal, 1.143 ms for Dy3+/Ca2+ LaF3 crystal were obtained, respectively. Besides yellow emissions, MIR emissions approximately at 3 μm are more appealing. Under 1280 nm excitation, the largest emission cross-sections of 0.304 × 10-20 cm2 at 2885 nm in Dy3+/Sr2+ LaF3 crystal, and 0.319 × 10-20 cm2 at 2880 nm in Dy3+/Ca2+ LaF3 crystal, together with rather long lifetimes of Dy3+ 6H13/2 in the level of milliseconds were achieved, making them useful media for MIR lasers.To study the interaction of the series of pyridinium based gemini surfactants (GS) (referred to as m-Py-m, m = 14, 16); 4,4′-(propane-1,3-diyl)bis(1-(2-(tetradecyloxy)-2-oxoethyl) dipyridinium chloride (14-Py-14), and 4,4′-(propane-1,3-diyl) bis(1-(2-(hexadecyloxy)-2-oxoethyl)dipyridinium chloride (16-Py-16) with bovine serum albumin (BSA), various physicochemical and spectroscopic tools such as tensiometry, steady-state fluorescence, synchronous fluorescence, pyrene fluorescence, UV-visible, far-UV circular dichroism (CD) were utilized at physiological pH (7.4) and 298 K in combination with computational molecular modeling analysis. The tensiometric results show significant modifications in interfacial and thermodynamic parameters for m-Py-m GS upon BSA combination, deciphering the gemini surfactant-BSA interaction. Steady-state fluorescence analysis evaluates the structural alterations of BSA with the addition of m-Py-m GS. The plots of Stern-Volmer, modified Stern-Volmer, and thermodynamic parameters were used to determine the binding type of m-Py-m GS to BSA. The synchronous fluorescence spectra state a mild effect of gemini surfactants on the emission intensity of tyrosine (Tyr) residues, on the other hand, tryptophan (Trp) residues showed a significant effect. Post addition of GS, the plot of pyrene fluorescence reveals the mild micropolarity fluctuations via the probe (pyrene) molecules encapsulated in BSA. UV-visible experiments support the complex formation between the BSA and m-Py-m GS. Far-UV CD measurements revealed the modifications in the secondary structure of protein produced by m-Py-m GS. Furthermore, we also used the computational molecular modeling for attaining deep insight into BSA and m-Py-m GS binding and the results are supported with our experimental results.Based on the green chemistry approach, highly fluorescent and novel carbon dots (C. dots) were synthesized from naturally available and cost effective sunflower seeds. The obtained C. dots showed a fluorescence quantum yield (Q.Y) of 9.5% with high water dispersibility and photostability. The obtained C. dots were employed for the detection of picric acid (PA) and bilirubin. A good linear relationship in the range of 20-60 nM was obtained for PA with a limit of detection (LOD) as low as 3.86 nM. C. dots were successfully incorporated in the agarose matrix which enabled them to be employed as a solid platform for the in situ detection of PA. The fluorescence of C. dots was selectively quenched by bilirubin compared to other biomolecules with a LOD of 2.03 μM. R16 cost Use of C. dots as potential candidate for bilirubin detection was verified by real sample analysis. Further, the separation of C. dots was performed using column chromatography and the optical properties of the two different fractions obtained were studied.
