<p class="abstract"><strong>Background:</strong> Arthroscopic anterior cruciate ligament (ACL) reconstruction can be performed using autograft from various sources namely, bone patellar tendon graft, hamstring tendons (semitendinosus, gracilis) or peroneus longus tendon.</p><p class="abstract"><strong>Methods:</strong> A prospective study of 30 patients who underwent arthroscopic ACL reconstruction using quadrupled semitendinosus tendon autograft and peroneus longus tendon autograft during the study period.<strong></strong></p><p class="abstract"><strong>Results:</strong> Statistically, there is very little comparable difference between semitendinosus and peroneus longus when used for arthroscopic ACL reconstruction. However, peroneus longus tendon shows superior results when used in patients with grade 3 medial collateral ligament (MCL) injury combined with ACL injury.</p><p class="abstract"><strong>Conclusions:</strong> Our study brings forth the superior efficacy and quality of the double stranded peroneus longus tendon especially in cases associated with complicated injuries involving the medial collateral ligament with a follow up date of about 2 years and as a healthy supplement to other choices of autografts and revision cases.</p>
Fluorene-chloroquine hybrids have been identified as a new promising class of antiplasmodial agents. The most active compound 9 d exhibited good in vitro antiplasmodial activity against a chloroquine-sensitive NF54 strain of the human malaria parasite Plasmodium falciparum with an IC 50 value of 139 nM. UV-visible absorption, FTIR spectral and 1 H NMR titration data corroborated the binding of 9 d to monomeric and μ-oxodimeric heme as well as inhibition of β-hematin formation, which collectively supported the inhibition of heme detoxification machinery in P. falciparum. In silico docking studies revealed the binding interactions of the hybrids in the active site of the wild type as well as quadruple mutant of Pf-DHFR-TS dihydrofolate enzyme. Further, the ADMET parameters were predicted and were in good agreement with the expected values, suggesting the drug likeness of the synthesized hybrid molecules.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
