HIV-1 low-level viremia predicts viral failure in participants on antiretroviral therapy in the Swiss HIV Cohort Study.

Background: Most individuals on combination antiretroviral therapy (ART) have HIV plasma viral loads below the limit of detection. However, episodes of low-level viremia (LLV) are observed in subsets of individuals, risk factors and clinical significance of which remain debated.

Methods: We included participants enrolled in the Swiss HIV Cohort Study, starting ART between July 1999 and April 2023, with HIV RNA <200 copies/ml six months post ART initiation.

Atlas of telomeric repeat diversity in Arabidopsis thaliana.

Background: Telomeric repeat arrays at the ends of chromosomes are highly dynamic in composition, but their repetitive nature and technological limitations have made it difficult to assess their true variation in genome diversity surveys.

Results: We have comprehensively characterized the sequence variation immediately adjacent to the canonical telomeric repeat arrays at the very ends of chromosomes in 74 genetically diverse Arabidopsis thaliana accessions. We first describe several types of distinct telomeric repeat units and then identify evolutionary processes such as local homogenization and higher-order repeat formation that shape diversity of chromosome ends.

Accelerating and breaking adaptive nano-colloids (<100 nm) into unsteady state operation push-pull effects.

Unlike conventional colloids showing random mobility because of Brownian motion, active colloids contain nanomotors that translate chemical or physical triggers into directed movement. Whereas the acceleration of such particles works well, it is difficult to decelerate them by request. Compared to the existing literature on microscaled swimmers/robots, the main question of the current paper is whether nanoscaled colloids (<100 nm) can also be actively controlled despite the stronger relevance of rotational diffusion at such dimensions.

Diploid genome assembly of the Malbec grapevine cultivar enables haplotype-aware analysis of transcriptomic differences underlying clonal phenotypic variation.

To preserve their varietal attributes, established grapevine cultivars ( L. ssp. ) must be clonally propagated, due to their highly heterozygous genomes.

The role of androgen deprivation therapy prior to radical prostatectomy in high-risk prostate cancer: a systematic review.

Introduction: Patients with high-risk prostate cancer (HRPCa) are prone to have worse pathological features, resulting in early biochemical recurrence after radical prostatectomy (RP). There is an urgent need to develop novel treatment strategies for this group of patients to optimize their outcomes. The purpose of this study is to perform a systematic review of the role of neoadjuvant hormonal therapy (NHT) followed by RP in HRPCa patients.

An evaluation of the German version of the Sensory Perception Quotient from an expert by experience perspective.

Sensory processing is often altered in individuals with autism; thus, it is essential to develop reliable measurement tools to assess sensory perception. The Sensory Perception Quotient (SPQ) quantifies basic sensory sensitivities in adults via self-report. Adopting an expert by experience perspective, this study aimed to evaluate a German translation of the SPQ for its use in clinical and research applications, especially for autistic adults.

Paleocene origin of a streamlined digestive symbiosis in leaf beetles.

Timing the acquisition of a beneficial microbe relative to the evolutionary history of its host can shed light on the adaptive impact of a partnership. Here, we investigated the onset and molecular evolution of an obligate symbiosis between Cassidinae leaf beetles and Candidatus Stammera capleta, a γ-proteobacterium. Residing extracellularly within foregut symbiotic organs, Stammera upgrades the digestive physiology of its host by supplementing plant cell wall-degrading enzymes.

Non-Classical Self-Assembly of Anisotropic Magneto-Organosilica Janus Particles Possessing Surfactant Properties and the Field-Triggered Breakdown of Surface Activity and Amphiphilic Properties.

Using colloidal particles as models to understand processes on a smaller scale is a precious approach. Compared to molecules, particles are less defined, but their architecture can be more complex and so is their long-range interaction. One can observe phenomena that are unknown or much more difficult to realize on the molecular level.

Cycles of satellite and transposon evolution in Arabidopsis centromeres.

Centromeres are critical for cell division, loading CENH3 or CENPA histone variant nucleosomes, directing kinetochore formation and allowing chromosome segregation. Despite their conserved function, centromere size and structure are diverse across species. To understand this centromere paradox, it is necessary to know how centromeric diversity is generated and whether it reflects ancient trans-species variation or, instead, rapid post-speciation divergence.

Diagnostic accuracy and clinical utility of micro-ultrasound guided biopsies in patients with suspected prostate cancer.

Introduction: New technologies to improve quality of prostate biopsies are appearing in clinical practice.We evaluate the performance of a micro-ultrasound device and the Prostate Risk Identification using MicroUltraSound (PRI-MUS) score in detecting clinically significant prostate cancer (csPCa).

Material And Methods: We retrospectively reviewed data of 139 biopsy- naïve patients with suspicion of prostate cancer, who underwent diagnostic MRI and micro-ultrasonography (microUS), followed by transrectal prostatic biopsy (systematic ±targeted) under local anesthetic.

Standing genetic variation fuels rapid evolution of herbicide resistance in blackgrass.

Repeated herbicide applications in agricultural fields exert strong selection on weeds such as blackgrass (), which is a major threat for temperate climate cereal crops. This inadvertent selection pressure provides an opportunity for investigating the underlying genetic mechanisms and evolutionary processes of rapid adaptation, which can occur both through mutations in the direct targets of herbicides and through changes in other, often metabolic, pathways, known as non-target-site resistance. How much target-site resistance (TSR) relies on de novo mutations vs.

Pushing the limits of HiFi assemblies reveals centromere diversity between two Arabidopsis thaliana genomes.

Although long-read sequencing can often enable chromosome-level reconstruction of genomes, it is still unclear how one can routinely obtain gapless assemblies. In the model plant Arabidopsis thaliana, other than the reference accession Col-0, all other accessions de novo assembled with long-reads until now have used PacBio continuous long reads (CLR). Although these assemblies sometimes achieved chromosome-arm level contigs, they inevitably broke near the centromeres, excluding megabases of DNA from analysis in pan-genome projects.

Number of lymph nodes sampled in SFCE/SIOP 2001 patients with Wilms tumour: Is the goal of more than six achievable?

Aim: The number of lymph nodes (LN) that should be sampled during nephrectomy for Wilms tumour (WT) remains controversial but of utmost importance for staging purposes. The aim of this French national retrospective study of patients enrolled in SIOPWT2001 trial was to analyse the number of LN sampled according to their site and to determine if the number of six asked by the International Society of Paediatric Oncology - Renal Tumour Study Group (SIOP-RTSG) UMBRELLA protocol is achievable.

Methods: We reviewed the data collected on central pathology review forms from 2002 to 2014 for only unilateral WT.

The leaf beetle Chelymorpha alternans propagates a plant pathogen in exchange for pupal protection.

Many insects rely on microbial protection in the early stages of their development. However, in contrast to symbiont-mediated defense of eggs and young instars, the role of microbes in safeguarding pupae remains relatively unexplored, despite the susceptibility of the immobile stage to antagonistic challenges. Here, we outline the importance of symbiosis in ensuring pupal protection by describing a mutualistic partnership between the ascomycete Fusarium oxysporum and Chelymorpha alternans, a leaf beetle.

The improved genome of the nematode Parapristionchus giblindavisi provides insights into lineage-specific gene family evolution.

Nematodes such as Caenorhabditis elegans and Pristionchus pacificus are extremely successful model organisms for comparative biology. Several studies have shown that phenotypic novelty but also conserved processes are controlled by taxon-restricted genes. To trace back the evolution of such new or rapidly evolving genes, a robust phylogenomic framework is indispensable.

Renal tumor biopsy does not increase the risk of surgical complications of minimally invasive partial nephrectomy.

Background: For patients with cT1 renal lesions, Partial Nephrectomy (PN) is the gold standard treatment. However, 20% of small renal masses are benign, situation in which the PN is an overtreatment. The percutaneous Renal Tumor Biopsy (RTB) may lower the risk of overtreatment as there is a 90% concordance rate on histotype between the RTB and the final pathology.

[Intravesical adjuvant regimen of epitubicin for intermediate risk NMIBC: Feasability study from CC-AFU vessie].

Introduction: Mitomycin C is the gold standard intravesical adjuvant therapy for intermediate-risk non-muscle-invasive bladder cancer (NMIBC). Tensions in the supply of mitomycin have emerged in France since late 2019. The ANSM in agreement with the AFU proposed to use epirubicin, already available in other European countries in this indication.

Chromosome-level Thlaspi arvense genome provides new tools for translational research and for a newly domesticated cash cover crop of the cooler climates.

Thlaspi arvense (field pennycress) is being domesticated as a winter annual oilseed crop capable of improving ecosystems and intensifying agricultural productivity without increasing land use. It is a selfing diploid with a short life cycle and is amenable to genetic manipulations, making it an accessible field-based model species for genetics and epigenetics. The availability of a high-quality reference genome is vital for understanding pennycress physiology and for clarifying its evolutionary history within the Brassicaceae.

Comparison of electrodiagnosis, neurosonography and MR neurography in localization of ulnar neuropathy at the elbow.

Introduction: In patients with ulnar neuropathy at the elbow (UNE) the precise determination of the site of lesion is important for subsequent differential diagnostic considerations and therapeutic management. Due to a paucity of comparable data, to better define the role of different diagnostic tests, we performed the first prospective study comparing the diagnostic accuracy of short segment nerve stimulation, nerve ultrasonography, MR neurography (MRN), and diffusion tensor imaging (DTI) in patients with UNE.

Methods: UNE was clinically diagnosed in 17 patients with 18 affected elbows.

IFITM3 incorporation sensitizes influenza A virus to antibody-mediated neutralization.

The disease severity of influenza is highly variable in humans, and one genetic determinant behind these differences is the IFITM3 gene. As an effector of the interferon response, IFITM3 potently blocks cytosolic entry of influenza A virus (IAV). Here, we reveal a novel level of inhibition by IFITM3 in vivo: We show that incorporation of IFITM3 into IAV particles competes with incorporation of viral hemagglutinin (HA).

Higher nodal yield with robot-assisted pelvic lymph node dissection for bladder cancer compared to laparoscopic dissection: implications for more accurate staging.

Objectives: To compare the lymph node (LN) yield and adequacy of laparoscopic pelvic lymph node dissection (L-PLND) and robot-assisted PLND (R-PLND), as PLND is a fundamental component of radical cystectomy (RC) for bladder cancer (BCa), where a positive status is the most powerful predictor of disease recurrence and survival.

Patents And Methods: We retrospectively reviewed patients undergoing RC with PLND for BCa from January 2007 to July 2019 and grouped them in to L- and R-PLND. Until 2011, patients underwent a standard PLND (S-PLND) with the cranial limit as bifurcation of common iliac artery.

Draft Genomes of Amaranthus tuberculatus, Amaranthus hybridus, and Amaranthus palmeri.

Amaranthus tuberculatus, Amaranthus hybridus, and Amaranthus palmeri are agronomically important weed species. Here, we present the most contiguous draft assemblies of these three species to date. We utilized a combination of Pacific Biosciences long-read sequencing and chromatin contact mapping information to assemble and order sequences of A.
