Objectives: To test whether or not one of six implantoplasty procedures is superior to the others rendering a minimal final implant surface roughness and a short treatment time.
Material And Methods: Forty-two one-piece implants were embedded in epoxy resin blocks with 6-mm rough implant surface exposed. The following implantoplasty polishing sequences were applied: Brownie(®) , Greenie(®) sequence (BG) (diamond rotary instruments 106-, 40-, 15-μm grit, Brownie(®) , Greenie(®) silicone polishers); Arkansas stone sequence (AS) (diamond 106-, 40-, 15-μm grit, Arkansas stone torpedo-shaped bur); Short diamond sequence (SD) (diamond 106-, 40-, 4-μm grit); Short diamond sequence with Greenie(®) (SDG) (diamond 106-, 40-, 4-μm grit, Greenie(®) ); Complete diamond sequence (CD) (diamond 106-, 40-, 15-, 8-, 4-μm grit); Complete diamond sequence with Greenie(®) (CDG) (106-, 40-, 15-, 8-, 4-μm grit, Greenie(®) ). The polished neck portion served as a positive control, the untreated sandblasted and acid-etched surface as negative control. Each implant was scanned with a contact profilometer rendering Ra values and Rz values as a measure of surface roughness. The time needed to polish the implant surface for each group was recorded. Simultaneous comparisons between more than two groups were done performing Kruskal-Wallis tests. Comparisons between two groups were analysed using Wilcoxon rank-sum tests.
Results: Mean Ra values amounted to 0.32 ± 0.14 μm (BG), 0.39 ± 0.13 μm (AS), 0.59 ± 0.19 μm (SDG), 0.71 ± 0.22 μm (SD), 0.75 ± 0.26 μm (CDG), 0.98 ± 0.30 μm (CD), 0.10 ± 0.01 μm (PC) and 1.94 ± 0.47 μm (NC). Pairwise one-sided comparisons between the test group revealed statistically significant differences (P < 0.05). The shortest treatment time was recorded for group AS (13 ± 2 min) and the longest for CDG (21 ± 2 min) and BG (21 ± 4 min).
Conclusions: Considering final surface roughness and treatment duration, the use of rotary diamond burs in decreasing roughness, followed by an arkansas stone (group AS), appears to be an optimal treatment option.

Antarctica is one of Earth's most untouched, inhospitable, and poorly known regions. Although knowledge of its biodiversity has increased over recent decades, a diverse, wide-ranging, and spatially explicit compilation of the biodiversity that inhabits Antarctica's permanently ice-free areas is unavailable. This absence hinders both Antarctic biodiversity research and the integration of Antarctica in global biodiversity-related studies.

Background: Concurrent exercise (CE), an emerging exercise modality characterized by sequential bouts of aerobic (AE) and resistance exercise (RE), has demonstrated acute benefits on executive functions (EFs) and neuroelectric P3 amplitude. However, the effect of acute CE on inhibitory control, a sub-component of EFs, and P3 amplitude remains inconclusive. Moreover, exploring the mechanisms underlying the effects of acute exercise on EFs contributes to scientific comprehension, with lactate recognized as a crucial candidate positively correlated with EFs.

Objectives: To determine the effectiveness of Levamisole (Leva) in maintaining short-term and long-term remission in early steroid responders (ESRs) and late steroid responders (LSRs).
Methods: This retrospective study on 106 cohorts, aged 2-14 years with frequent-relapsing (FR) and steroid-dependent nephrotic syndrome (SDNS) who received Leva over 10-years (2012-2023), was carried out at tertiary care centre, Karachi from January-August 2023. Patients were categorized based on steroid response during first episode of NS as ESRs if complete remission (CR) was achieved within two weeks of daily steroid and LSRs if CR achieved between two-four weeks.
