Avaliação das medidas do comprimento peniano de crianças e adolescentes Penile anthropometry in Brazilian child and adolescent

open access: yesJornal de Pediatria, 2007
OBJETIVO: Classicamente, o pênis tem duas funções: permitir a fertilização interna e direcionar o jato miccional. Entretanto, alterações objetivas do tamanho peniano podem levar ao diagnóstico de doenças.

Integrated Single‐Cell and Spatial Transcriptomics Reveal Cell‐Type‐Specific Immune Regulatory Networks in Maize Responding to Southern Corn Rust

open access: yesAdvanced Science, EarlyView.
By integrating single‐nuclei and spatial transcriptomics, this study presents a stereoscopic landscape of maize leaf to Puccinia polysora infection. Epidermal and mesophyll cells initiate primary defenses via RLPs/RLKs and jasmonic acid signaling. Cell‐cell communication analyses further reveal the underlying the dynamics of the underlying immune ...

On the Origins of Toughness in Corymbia calophylla (Marri Tree) Nuts

open access: yesAdvanced Science, EarlyView.
We uncover the natural toughening mechanisms of the marri nut, including fiber pullout, crack deflection, and a viscoelastic matrix, which enable exceptional energy absorption and ductility comparable to Teflon, with an elastic modulus similar to acrylic.

Engineering Compact Base Editors by AlphaFold‐Guided Mutation Scan and Escherichia coli‐Based Tri‐Selection

open access: yesAdvanced Science, EarlyView.
A miniaturized deaminase SsdAtox was scanned with AlphaFold to identify DNA binding pocket hot spots. Site‐saturation mutagenesis at gatekeeper residue K31 yielded ten‐fold activity enhancement. Trinity Screen, an E. coli‐based three‐in‐one platform selecting for high activity and reduced double‐strand breaks, enabled combinatorial evolution at DNA ...

Neuroprotective Effects of Time‐Restricted Feeding Combined With Different Protein Sources in MPTP‐Induced Parkinson's Disease Mice Model and Its Modulatory Impact on Gut Microbiota Metabolism

open access: yesAdvanced Science, EarlyView.
Time‐restricted feeding (TRF) exerts protein‐dependent neuroprotective effects in an MPTP‐induced Parkinson's disease model. In casein‐fed mice, TRF improves gut barrier integrity and reduces neuroinflammation, possibly via modulation of Allobaculum and BCAAs.

Hypofractionated Radiotherapy Induces ISG15+MHC‐I+ Neutrophils to Augment Anti‐Tumor Immunity and Prime Immune Checkpoint Blockade Responses in Rectal Cancer

open access: yesAdvanced Science, EarlyView.
ABSTRACT Our previous clinical trials had demonstrated that neoadjuvant hypofractionated radiotherapy (HFRT) combined with immunotherapy yields promising clinical outcomes in locally advanced rectal cancer (LARC). However, this combined modality benefits only a subset of patients, highlighting the need to uncover the mechanisms underlying how ...

Synergistic Hydrogen‐Bonding and Covalent Crosslinking in Polybenzimidazole Membranes for Wide‐Temperature Anhydrous Fuel Cells

open access: yesAdvanced Science, EarlyView.
A dual‐network architecture combining a thermally reinforced hydrogen‐bonding matrix with an amine‐anhydride covalent framework was constructed in Tröger's Base (TB)‐functionalized polybenzimidazoles. This design yielded the TBAm‐PBI‐TB membrane with high acid uptake (469.5%), anhydrous conductivity (264.7 mS cm−1), and robust stability.

Doped low-density parity-check codes

open access: yesDigital Communications and Networks
In this paper, we propose a doping approach to lower the error floor of Low-Density Parity-Check (LDPC) codes. The doping component is a short block code in which the information bits are selected from the coded bits of the dominant trapping sets of the ...

High‐Performance Recycling Biobased Photopolymers for 3D Printing

open access: yesAdvanced Science, EarlyView.
By using biobased phenols like eugenol, novel biobased photopolymers containing dissociative phenol‐carbamate bonds are designed for 3D printing. Meanwhile, a “mixed‐monomer assisted recycling” strategy is proposed to recycle the materials. The resulting materials not only achieve high‐performance and excellent chemical recyclability simultaneously ...

Recycled Piezoelectric Materials with Competitive Second‐Life Functional Properties

open access: yesAdvanced Electronic Materials, EarlyView.
The essential piezoelectric ceramics with heavy ecological footprints are not sufficiently recycled. This work demonstrates the feasibility of recycling different types of piezoelectric ceramics using different binders, where the terpolymer binder with relatively large permittivity facilitated superior retention of properties after recycling, promoting
