Surgical gestures—An emerging field for surgical assessment and training

UroPrecision, EarlyView.
Abstract As surgical training shifts from a traditional method to a more standardized approach, objective analysis and assessment of surgeon performance has become a key focus. Surgical gestures, defined as the smallest independent units of instrument‐tissue interaction, offer a quantifiable way to analyze surgical performance.

Altered activity within the social behavior neural network in adolescent rats following prenatal alcohol exposure and/or early‐life adversity

Alcohol, Clinical and Experimental Research, EarlyView.
Prenatal alcohol exposure (PAE) and early‐life adversity (ELA) independently and interactively disrupted neural activity within the social behavior network in adolescent rats, with age‐ and sex‐specific effects. PAE primarily dampened amygdala activity, while ELA altered medial prefrontal cortex responses. These findings reveal how different early‐life

Utilization of Free and Esterified Gholesterol-4-G14 for Corticoid Biosynthesis by Hog Adrenal Homogenates.

Experimental Biology and Medicine, 1962
SummaryTracer amounts of cholesterol-4-C14 added to hog adrenal homogenates and incubated under conditions favorable for steroid synthesis were rapidly and efficiently converted to labeled steroids. Addition of cholesterol-4-C14 esters, prepared enzymatically and incubated under the same conditions, did not give C14-activity in the steroids produced ...

How data or error covariance can change and still retain BLUEs as well as their covariance or the sum of squares of errors

Australian &New Zealand Journal of Statistics, EarlyView.
Summary Misspecification of the error covariance in linear models usually leads to incorrect inference and conclusions. We consider two linear models, A$$ \mathcal{A} $$ and B$$ \mathcal{B} $$, with the same design matrix but different error covariance matrices. The conditions under which every representation of the best linear unbiased estimator (BLUE)

Mitochondrial Mutation Leads to Cardiomyocyte Hypertrophy by Disruption of Mitochondria‐Associated ER Membrane

Cell Proliferation, EarlyView.
Cardiomyocytes with high m.3243A>G burden exhibited hypertrophic phenotype. Mitochondria dysfunction occurred and tended to become round in cardiomyocytes with high m.3243A>G burden. Mitochondria‐associated ER membrane (MAM) was disrupted in cardiomyocytes with high m.3243A>G burden.

The crystal structure of Giardia duodenalis 14-3-3 in the apo form: when protein post-translational modifications make the difference. [PDF]

PLoS ONE, 2014
The 14-3-3s are a family of dimeric evolutionary conserved pSer/pThr binding proteins that play a key role in multiple biological processes by interacting with a plethora of client proteins.

The Impact of Dietary Intake and Nutritional Status on the Oral Health of Older Adults Living in Care Homes: A Scoping Review

Gerodontology, EarlyView.
ABSTRACT Objectives To review the literature on the relationship between oral health, dietary intake, and nutritional status in older adults in care homes, identifying research gaps. Background Many older adults in care homes retain natural teeth but face oral health issues due to challenges in maintaining hygiene and limited dental care access.

Not all social coral reef fishes form strict size‐based dominance hierarchies: An investigation of intraspecific size ratios in Dascyllus aruanus

Journal of Fish Biology, EarlyView.
Abstract We present a random pattern of body size ratios between adjacent ranked group members in the humbug damselfish Dascyllus aruanus. This random distribution of size ratios differs from the other well‐known group‐living coral reef fishes which exhibit non‐random, well‐defined and closely regulated size differences between ranks.
