Our objective was to enhance the existing diagnostic criteria and assess their sensitivity and specificity for identifying neurosyphilis in HIV-negative patients. We conducted a retrospective review of patient records from a cross-sectional study carried out between December 2019 and May 2023.

Design of highly leaf-adhesive and anti-UV herbicide nanoformulation for enhanced herbicidal activity.

Introduction: Conventional pesticide formulations have been widely used to boost agricultural productivity, but their weak foliar adhesion and instability under UV light during spraying lead to low utilization rates and potential environmental and health hazards. To counter these challenges, the development of nanoformulations represents a pivotal strategy. These advanced formulations are designed to enhance the efficacy of active ingredients (AIs) and reduce ecological impacts, thereby addressing the need for sustainable agricultural development.

Identification and function analysis of Toll-like receptor 4 (TLR4) from Manila clam (Ruditapes philippinarum).

Toll-like receptor 4 (TLR4) is a pattern recognition receptor that activates innate immunity in response to pathogen infection. However, the role of TLR4 in pathogen-induced apoptosis and host immunity in mollusks remains largely unknown. In this study, the TLR4 of the Manila clam Ruditapes philippinarum (RpTLR4) was cloned.

Highly Efficient Mediated Transformation of Oil Palm Using an -Glyphosate Selection System.

Oil palm ( Jacq.) is the most efficient oil-producing crop globally, yet progress in its research has been hampered by the lack of effective genetic transformation systems. The gene, encoding 5-enolpyruvylshikimate-3-phosphate synthase, has been used as a transgenic selection marker in various crops, including rice and soybean.

Collimated flat-top beam shaper metasurface doublet based on the complex-amplitude constraint Gerchberg-Saxton algorithm.

Collimated flat-top beam shapers primarily consisting of freeform lenses have a wide range of applications and pose challenges in terms of processing and integration when the diameter is less than millimeters. Metasurfaces represent a promising solution to planarize optics, can mimic any surface curvature without additional fabrication difficulty, and are suitable for flat-top optics. The conventional metasurface design approach relies on imparting the required phase using meta-atoms and encounters challenges in amplitude modulation due to near-field coupling and varying transmittances among meta-atoms with different phases, making the design of flat-top beam shapers difficult.

Induction and Transcriptome Analysis of Callus Tissue from Endosperm of Makapuno Coconut.

The makapuno coconut endosperm is distinguished by its soft and irregular texture, in contrast to the solid endosperm of regular coconuts. To establish a scientific foundation for studying makapuno coconuts, callus was induced from makapuno endosperm using a combination of plant growth regulators. The induction was successful, and the resulting callus was subsequently subcultured for further study.

Injectable polyethylene glycol/methacrylated polylysine double cross-linked hydrogel releases neuropeptides for infected wound healing.

Wound infections caused by microorganisms often give rise to extensive inflammation and vascular damage that compromise the wound healing process. Designing approaches to more effectively controlling wound infections and accelerating this healing process are urgently needed. This study was designed with the goal of synthesizing an injectable, double cross-linked hydrogel suitable for use when treating infected wounds.

Research progress of natural products targeting tumor-associated macrophages in antitumor immunity: A review.

As an important innate immune cell in the body, macrophages have a strong ability to phagocytic tumor cells and maintain the innate immune response. Tumor-associated macrophages play a more prominent role in regulating tumor immunity and are currently an important target of antitumor immunity. As a new type of antitumor therapy, tumor immunotherapy has great potential, combined chemotherapy, targeting and other therapeutic means can significantly enhance the antitumor therapy effect.

PANoptosis in autoimmune diseases interplay between apoptosis, necrosis, and pyroptosis.

PANoptosis is a newly identified inflammatory programmed cell death (PCD) that involves the interplay of apoptosis, necrosis, and pyroptosis. However, its overall biological effects cannot be attributed to any one type of PCD alone. PANoptosis is regulated by a signaling cascade triggered by the recognition of pathogen-associated molecular patterns (PAMPs) and damage-associated molecular patterns (DAMPs) by various sensors.

Flavor properties of post-heated fermented milk revealed by a comprehensive analysis based on volatile and non-volatile metabolites and sensory evaluation.

Existing research on the post-heating processing of fermented milk has primarily focused on single post-heating treatments and the texture, while research on how changes in metabolites during different post-heating treatments affect flavor and sensory properties is limited. This study investigates the changes in volatile metabolites in fermented milk treated at different post-heating temperatures to determine the characteristic aroma types and analyzes the changes in non-volatile metabolites associated with aroma-active compounds or their precursors to clarify the causes of the altered flavor and sensory properties. The results showed that in the 65 °C and 75 °C treatments, 63 volatile compounds were produced by Strecker degradation, lipid oxidation and esterification to produce ketones and aldehydes.

ZmCCD8 regulates sugar and amino acid accumulation in maize kernels via strigolactone signalling.

How carbon (sucrose) and nitrogen (amino acid) accumulation is coordinatively controlled in cereal grains remains largely enigmatic. We found that overexpression of the strigolactone (SL) biosynthesis gene CAROTENOID CLEAVAGE DIOXYGENASE 8 (CCD8) resulted in greater ear diameter and enhanced sucrose and amino acid accumulation in maize kernels. Loss of ZmCCD8 function reduced kernel growth with lower sugar and amino acid concentrations.

Effect of laser wavelength on the quantitative analysis performance of indirect ablation LIBS for analyzing the metals in lubricating oil.

For monitoring the lubricant quality and engine wear status, indirect ablation laser-induced breakdown spectroscopy (LIBS) was introduced to determine the metal elements in lubricating oil. Due to the different transmittance values of oil at different laser wavelengths, the effect of the laser wavelength on the detection performance of indirect ablation LIBS was studied. Under optimal parameters, the calibration curves were established for 10 metal elements with laser wavelengths of 1064, 532, and 355 nm.

Dual-targeted TfRA4-DNA1-Ag@AuNPs: An innovative radiosensitizer for enhancing radiotherapy in glioblastoma multiforme.

Radiation therapy (RT) is one of the most effective and widely used treatment methods for glioblastoma multiforme (GBM). However, its efficacy is often compromised by the inherent radioresistance of tumor cells, while the restrictive nature of the blood-brain barrier (BBB) specifically impedes the delivery of radiosensitizer. Thus, we constructed and characterized polyethylene glycol (PEG)-functionalized silver-gold core-shell nanoparticles (PSGNPs) targeting both BBB (TfRA4) and GBM (DNA1) (TDSGNPs).
