Survival and cause-specific mortality rates are vital for evidence-based population forecasting and conservation, particularly for large carnivores, whose populations are often vulnerable to human-caused mortalities. It is therefore important to know the relationship between anthropogenic and natural mortality causes to evaluate whether they are additive or compensatory. Further, the relation between survival and environmental covariates could reveal whether specific landscape characteristics influence demographic performance.

Optimizing automated photo identification for population assessments.

Conserv Biol

January 2025

Marine Mammal Research Program, Hawai'i Institute of Marine Biology, University of Hawai'i at Mānoa, Kāne'ohe, Hawai'i, USA.

Several legal acts mandate that management agencies regularly assess biological populations. For species with distinct markings, these assessments can be conducted noninvasively via capture-recapture and photographic identification (photo-ID), which involves processing considerable quantities of photographic data. To ease this burden, agencies increasingly rely on automated identification (ID) algorithms.

Biomarkers for anti-angiogenic drugs in chemo-refractory metastatic colorectal cancer (mCRC) are lacking. We investigated the relationship between stanniocalcin 1 (STC1) and outcomes in patients treated with regorafenib in the TEXCAN and CORRECT trials. Baseline plasma STC1 protein levels were measured by ELISA from patients with chemo-refractory mCRC enrolled in TEXCAN (regorafenib n=48) and CORRECT (placebo n=211; regorafenib n=435).

Continuous and reagentless biomolecular detection technologies are bringing an evolutionary influence on disease diagnostics and treatment. Aptamers are attractive as specific recognition probes because they are capable of regeneration without washing. Unfortunately, the affinity and dissociation kinetics of the aptamers developed to date show an inverse relationship, preventing continuous and reagentless detection of protein targets due to their low dissociation rates.

Background: Classical-like Ehlers Danlos Syndrome type 1 (clEDS1) is a very rare form of Ehlers Danlos Syndrome (EDS) caused by tenascin-X (TNX) deficiency, with only 56 individuals reported. TNX is an extracellular matrix protein needed for collagen stability. Previous publications propose that individuals with clEDS1 might be at risk for gastrointestinal (GI) tract perforations and/or tracheal ruptures.

Why Does an "Avatar Nose" Appear After Dermal Filler Injection? Insights From a Cadaveric Study on the Nasofrontal Ligament.

Dermatol Surg

January 2025

Division in Anatomy and Developmental Biology, Department of Oral Biology, Human Identification Research Institute, BK21 FOUR Project, Yonsei University College of Dentistry, Seodaemun-gu, Seoul, Korea.

Background: Nonsurgical rhinoplasty (NSR) with dermal fillers has gained popularity because of its immediate and visible results, minimal downtime, and long-lasting effects. However, complications such as filler migration can lead to the development of the "Avatar nose," a condition where the nose appears unnaturally wide and bulbous in the nasion area, disrupting facial harmony. This phenomenon is often exacerbated by the presence of a taut nasofrontal ligament, which tethers the periosteum to the dermal layer and influences nasal contour.

Anisometric plasmonic nanoparticles find applications in various fields, from photocatalysis to biosensing. However, exposure to heat or to specific chemical environments can induce their reshaping, leading to loss of function. Understanding this process is therefore relevant both for the fundamental understanding of such nano-objects and for their practical applications.

Placebo effect represents a serious confounder for the assessment of treatment effect to the extent that it has become increasingly difficult to develop antidepressant medications appropriate for outperforming placebo. Treatment effect in randomized, placebo-controlled trials, is usually estimated by the mean baseline adjusted difference of treatment response in active and placebo arms and is function of treatment-specific and non-specific effects. The non-specific treatment effect varies subject by subject conditional to the individual propensity to respond to placebo.

The article provides an important warning but its general conclusions should be nuanced: (i) When there is no evidence for it, we should depart from the hypothesis that a species lacks a particular cognitive capacity, and (ii) inferences from absence of evidence can be epistemically sound and scientifically strategic in cognitive and linguistic archaeology.

Revising the null model in language evolution research.

Behav Brain Sci

January 2025

Department of Experimental Linguistics, Centre for Language Evolution Studies, Nicolaus Copernicus University in Toruń, Toruń,

We comment on the consequences of the target article for language evolution research. We propose that the default assumption should be that of language-readiness in extinct hominins, and the integration of different types of available evidence from multiple disciplines should be used to assess the likely extent of the realization of this readiness. The role of archaeological evidence should be reconsidered.

Predictive modelling of acute Promyelocytic leukaemia resistance to retinoic acid therapy.

Brief Bioinform

November 2024

Department of Biology, École Normale Supérieure, 46 rue d'Ulm, 75005 Paris, France.

Acute Promyelocytic Leukaemia (APL) arises from an aberrant chromosomal translocation involving the Retinoic Acid Receptor Alpha (RARA) gene, predominantly with the Promyelocytic Leukaemia (PML) or Promyelocytic Leukaemia Zinc Finger (PLZF) genes. The resulting oncoproteins block the haematopoietic differentiation program promoting aberrant proliferative promyelocytes. Retinoic Acid (RA) therapy is successful in most of the PML::RARA patients, while PLZF::RARA patients frequently become resistant and relapse.

Introduction: Using an Asian cohort with high prevalence of concomitant cerebrovascular disease (CeVD), we evaluated the performance of a plasma immunoassay for tau phosphorylated at threonine 217 (p-tau217) in detecting amyloid beta positivity (Aβ+) on positron emission tomography and cognitive decline, based on a three-range reference, which stratified patients into low-, intermediate-, and high-risk groups for Aβ+.

Methods: Brain amyloid status (Aβ- [n = 142] vs Aβ+ [n = 73]) on amyloid PET scans was assessed along with the plasma ALZpath p-tau217 assay to derive three-range reference points for PET Aβ+ based on 90% sensitivity (lower threshold) and 90% specificity (upper threshold).

Results: Plasma p-tau217 (area under the curve [AUC] = 0.

Study Question: Is there an association between dydrogesterone exposure during early pregnancy and the reporting of birth defects?

Summary Answer: This observational analysis based on global safety data showed an increased reporting of birth defects, mainly hypospadias and congenital heart defects (CHD), in pregnancies exposed to dydrogesterone, especially when comparing to progesterone.

What Is Known Already: Intravaginal administration of progesterone is the standard of care to overcome luteal phase progesterone deficiency induced by ovarian stimulation in ART. In recent years, randomized controlled clinical trials demonstrated that oral dydrogesterone was non-inferior for pregnancy rate at 12 weeks of gestation and could be an alternative to micronized vaginal progesterone.
