Mechanisms of Post-Stroke Stiff Knee Gait: A Narrative Review.

Stiff-Knee gait (SKG) is a dysfunction commonly observed post-stroke characterized by a decreased swing phase knee flexion angle. Importantly, SKG can impair walking, ultimately reducing overall activity and participation. Interventions for SKG have shown mixed results, and combined with more recent observational evidence, suggest that there are other potential causes requiring the need to re-examine the etiology of SKG.

Evaluation of objective methods for analyzing ipsilateral motor evoked potentials in stroke survivors with chronic upper extremity motor impairment.

Ipsilateral motor evoked potentials (iMEPs) are believed to represent cortically evoked excitability of uncrossed brainstem-mediated pathways. In the event of extensive injury to (crossed) corticospinal pathways, which can occur following a stroke, uncrossed ipsilateral pathways may serve as an alternate resource to support the recovery of the paretic limb. However, iMEPs, even in neurally intact people, can be small, infrequent, and noisy, so discerning them in stroke survivors is very challenging.

Enrichment effects on growth, health, and reproduction in a single clone of the asexual Amazon molly, .

This study examines the impact of two types of environmental enrichment on the growth of the Amazon molly (), a clonal fish species. We investigated the effects of two welfare-related enrichment factors: physical enrichment (presence of a halfpipe PVC and gravel substrate, E) and social enrichment (presence of visible neighbor fish, N). Fish were divided into four treatment groups: (1) both physical and social enrichment (EN), (2) no physical enrichment but social enrichment (nEN), (3) physical enrichment without social enrichment (EnN,), and (4) no enrichment (nEnN).

Pancreatic Adenocarcinoma: Long-Term Outcomes of Adjuvant Therapy in the ESPAC4 Phase III Trial.

Purpose: The ESPAC4 trial showed that adjuvant chemotherapy with gemcitabine plus capecitabine (GemCap) produced longer overall survival (OS) than gemcitabine monotherapy. Subsequently, the PRODIGE24-CCTG PA.6 trial showed even longer survival for modified fluorouracil, folinic acid, irinotecan, and oxaliplatin (mFOLFIRINOX) than gemcitabine but had more restrictive eligibility criteria.

Combination Low-Dose Pilocarpine/Diclofenac Sodium and Pilocarpine Alone for Presbyopia: Results of a Randomized Phase 2b Clinical Trial.

Purpose: To evaluate the efficacy of 0.2% and 0.4% pilocarpine HCl (CSF-1) for the treatment of presbyopia and to determine the contributions of pilocarpine HCl and diclofenac sodium on the efficacy of fixed-dose combination (FDC) formulations.
