Hülsmann and Hartig suggest that ecological mechanisms other than specialized natural enemies or intraspecific competition contribute to our estimates of conspecific negative density dependence (CNDD). To address their concern, we show that our results are not the result of a methodological artifact and present a null-model analysis that demonstrates that our original findings-(i) stronger CNDD at tropical relative to temperate latitudes and (ii) a latitudinal shift in the relationship between CNDD and species abundance-persist even after controlling for other processes that might influence spatial relationships between adults and recruits.

Background: The CRP-albumin-lymphocyte (CALLY) index has potential clinical value as a novel marker integrating inflammatory, nutritional and immune status in the development of colorectal polyps. This study examined whether gender factors influence the association between CALLY and colorectal polyps; in addition to elucidating whether metabolic pathways mediate this relationship.
Methods: This is a cross-sectional study including 5409 adult health screening participants who completed colonoscopy.

The utilization of synergistic multivalent active sites holds potential in addressing the inherent sluggish kinetics of electrocatalytic reactions. Herein, we prepared au uNPs/Ni-NDC (NDC = 1,4-Naphthalenedicarboxylic acid) and leveraged the localized surface plasmon resonance (LSPR) effect to drive hot electron transfer from au nanoparticles to the Ni substrate, thereby generating multivalent active sites to boost the urea oxidation reaction (UOR). Under exciting light, au uNPs/Ni-NDC exhibited a twofold increase in UOR current accompanied by a significant negative shift in onset potential.

Tumor-associated neutrophils (TANs) play a critical role in breast cancer progression. This study demonstrated that high CD66b TANs infiltration correlated with poor disease-free survival (DFS) and promoted proliferation, migration, and invasion of breast cancer cells in vitro. Conversely, the immune-related long non-coding RNA C6orf99 was downregulated in breast cancer and associated with favorable DFS.

This study investigated the correlation between the strength of correlated effective neural drive (END) to the antagonistic muscles and the fluctuations in neural/electrical and mechanical output around the joint during steady co-contraction, and whether the correlated END strength estimated from conventional surface EMG is correlated with that determined from motor unit (MU) discharges. Fourteen young male participants performed isometric steady co-contractions with their medial gastrocnemius and tibialis anterior muscles at 10% of maximal EMG while sitting. Correlated END strength was quantified as the maximum value of the cross-correlation function between the conventional surface EMG signals and between MU discharges decomposed from high-density surface EMG of each muscle.

Objective: This study aimed to identify distinct REM sleep characteristics that differentiate type 1 narcolepsy (NT1) from type 2 narcolepsy (NT2) using polysomnography (PSG), while acknowledging the need for future validation against other hypersomnia disorders.
Methods: A retrospective review included 31 patients with NT1, 21 patients with NT2, and 24 healthy participants. Each participant underwent overnight PSG and a subsequent multiple sleep latency test (MSLT) to assess REM sleep parameters including average REM density, neck myoclonus index, and leg movement index.
