Practical indistinguishability in a gene regulatory network inference problem, a case study.

Computationally inferring mechanistic insights from typical biological data is a challenging pursuit. Even the highest-quality experimental data come with challenges. There are always sources of noise, a limit to how often we can measure the system, and we can rarely measure all the relevant states that participate in the underlying complexity.

Developmental transcriptomics in reveals the environmental responsiveness of a plasticity gene-regulatory network.

Developmental plasticity enables the production of alternative phenotypes in response to different environmental conditions. Although significant advances in understanding the ecological and evolutionary implications of plasticity have been made, understanding its genetic basis has lagged. However, a decade of genetic screens in the model nematode has culminated in the identification of more than 30 genes that affect mouth form.

Extended sperm search and microfreeze for fertility preservation after long-term hormone therapy in transgender women: a report of three cases.

Background: Many barriers prevent transgender women (TW) from fertility preservation (FP) prior to initiating gender-affirming hormones. The decision to move forward with gender affirming bottom surgery presents the last opportunity for these patients to preserve their ability to have genetically related children. However, oftentimes these patients will have azoospermia even after stopping their hormone therapy for an extended period due to the negative effects of these hormones on fertility.

Animal septins contain functional transmembrane domains.

Septins are a highly conserved family of proteins that form palindromic hetero-oligomeric rods, which anneal into non-polar filaments. Via association with the plasma membrane, septin filaments recognize micron-scale membrane curvature, create diffusion barriers, and regulate cell morphogenic events via scaffolding other cytoskeletal polymers (i.e.

Lessons on the force-form-function connection in cell biology from modeling a syncytial germline.

Germline architecture plays a critical role in the production of functional gametes. Across species, oogenesis involves not only the preparation of the genome for sexual reproduction, but also the dramatic enlargement of a cell compartment to reach a volume sufficient to support embryogenesis. Creating exceptionally large cells is accomplished by a syncytial structure, in which many nucleus-containing compartments are interconnected by cytoplasmic bridges.

Time-dependent effects of ethanol-glycerin embalming on iliotibial band biomechanics.

When conducting biomechanical testing or clinical training using embalmed human soft tissues, it is essential to understand their impact on biomechanical properties and their time dependence. Previous studies have investigated this influence, but specific variations over different embalming durations have not been thoroughly addressed to date. Ninety-seven human iliotibial band specimens were obtained from nine donors.

Financial Toxicity Among Patients With Advanced Solid Tumors Participating in Early-Phase Clinical Trials.

Purpose: Financial toxicity (FT) adversely influences patient quality of life and is a barrier to clinical trial enrollment. Early-phase clinical trials (EPCTs) recruit patients who may have high baseline FT and require additional visits and procedures, potentially increasing FT.

Methods: In this prospective survey study, we sought to assess FT at baseline and after 2 months among patients with advanced solid malignancies participating in EPCTs.

Developmental transcriptomics in reveals the logic of a plasticity gene regulatory network.

Developmental plasticity enables the production of alternative phenotypes in response to different environmental conditions. While significant advances in understanding the ecological and evolutionary implications of plasticity have been made, understanding its genetic basis has lagged. However, a decade of genetic screens in the model nematode has culminated in 30 genes which affect mouth-form plasticity.

Subcellular context-specific tuning of actomyosin ring contractility within a common cytoplasm.

The non-muscle actomyosin cytoskeleton generates contractile force through the dynamic rearrangement of its constituent parts. Actomyosin rings are a specialization of the non-muscle actomyosin cytoskeleton that drive cell shape changes during division, wound healing, and other events. Contractile rings throughout phylogeny and in a range of cellular contexts are built from conserved components including non-muscle myosin II (NMMII), actin filaments (F-actin), and crosslinking proteins.

Functional and radiological sinonasal outcomes of CFTR modulators for sinus disease in cystic fibrosis: A meta-analysis.

Background: Cystic fibrosis transmembrane conductance regulator (CFTR) modulators improve pulmonary outcomes in cystic fibrosis (CF) by stabilizing the CFTR protein on respiratory epithelial surfaces. To determine the efficacy of CFTR modulators on sinonasal outcomes in patients with CF, we performed a meta-analysis of clinical trials to date that include functional and radiographic evidence of sinus disease.

Methods: English full-text articles were searched in PubMed, Embase, and Scopus databases.

Orbital preservation in the treatment of acute invasive fungal sinusitis.

Acute invasive fungal sinusitis (AIFS) is an aggressive disease with significant mortality and morbidity. Surgical debridement is a mainstay of treatment. However, orbital involvement may limit its efficacy and is an independent risk factor for mortality.

Extranodal marginal zone lymphoma of the larynx: A case report and scoping review.

Background: This scoping review aims to review cases of extranodal marginal zone lymphoma (MZL) of the larynx to establish best management practices for this rare clinical entity.

Methods: In this paper, we report a case of laryngeal MZL, in accordance with CARE guidelines. We then performed a scoping review according to PRISMA-ScR criteria of published cases of MZL involving the larynx.

Mechanical and biochemical feedback combine to generate complex contractile oscillations in cytokinesis.

The actomyosin cortex is an active material that generates force to drive shape changes via cytoskeletal remodeling. Cytokinesis is the essential cell division event during which a cortical actomyosin ring closes to separate two daughter cells. Our active gel theory predicted that actomyosin systems controlled by a biochemical oscillator and experiencing mechanical strain would exhibit complex spatiotemporal behavior.

An exploration into the relationship between insomnia and repetitive negative thinking among cancer survivors.

Objective: Insomnia and repetitive negative thinking (RNT) are both prevalent among cancer survivors, yet little work has investigated their interrelationship. To explore the hypothesis that RNT and insomnia are related, we conducted secondary analyses on data from a pilot clinical trial of cognitive behavioral therapy for insomnia (CBT-I) for cancer survivors.

Methods: This study analyzed survey data from 40 cancer survivors with insomnia who participated in a pilot randomized trial of CBT-I.

A phase 3b study of venetoclax and azacitidine or decitabine in an outpatient setting in patients with acute myeloid leukemia.

Venetoclax, a highly selective BCL-2 inhibitor, combined with hypomethylating agents (HMAs) azacitidine or decitabine, is approved for the treatment of newly diagnosed acute myeloid leukemia (ND AML) in patients who are ineligible to receive intensive chemotherapy. Previous clinical studies initiated venetoclax plus HMA in an inpatient setting owing to concerns of tumor lysis syndrome (TLS). This study (NCT03941964) evaluated the efficacy and safety of venetoclax plus HMA in a United States community-based outpatient setting in patients with ND AML (N = 60) who were treatment naïve for AML, ineligible to receive intensive chemotherapy, had no evidence of spontaneous TLS at screening, and were deemed as appropriate candidates for outpatient initiation of venetoclax plus HMA by the investigator.

Newly identified nematodes from the Great Salt Lake are associated with microbialites and specially adapted to hypersaline conditions.

Extreme environments enable the study of simplified food-webs and serve as models for evolutionary bottlenecks and early Earth ecology. We investigated the biodiversity of invertebrate meiofauna in the benthic zone of the Great Salt Lake (GSL), Utah, USA, one of the most hypersaline lake systems in the world. The hypersaline bays within the GSL are currently thought to support only two multicellular animals: brine fly larvae and brine shrimp.

Analysis of the Technical Accuracy of a Patient-Specific Stereotaxy Platform for Brain Biopsy.

The use of stereotactic frames is a common practice in neurosurgical interventions such as brain biopsy and deep brain stimulation. However, conventional stereotactic frames have been shown to require modification and adaptation regarding patient and surgeon comfort as well as the increasing demand for individualized medical treatment. To meet these requirements for carrying out state-of-the-art neurosurgery, a 3D print-based, patient-specific stereotactic system was developed and examined for technical accuracy.

After providing a brief historical perspective, this review will focus on the relevant primary literature published in the last ten years.

Mechanical positive feedback and biochemical negative feedback combine to generate complex contractile oscillations in cytokinesis.

Contractile force generation by the cortical actomyosin cytoskeleton is essential for a multitude of biological processes. The actomyosin cortex behaves as an active material that drives local and large-scale shape changes via cytoskeletal remodeling in response to biochemical cues and feedback loops. Cytokinesis is the essential cell division event during which a cortical actomyosin ring generates contractile force to change cell shape and separate two daughter cells.
