Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Anti-Inflammatory, Antipyretic, and Analgesic Potential of Chitin and Chitosan Derived from Cockroaches (Periplaneta americana) and Termites

Journal of Functional Biomaterials
The chitin and chitosan biopolymers are extremely valuable because of their numerous industrial and pharmacological uses. Chitin and chitosan were extracted from the exoskeleton of Periplaneta americana (cockroaches) and termites using various acid and ...

From nature to nanoscale: advances, challenges, and preclinical translation of nanofiber drug delivery systems containing plant‐derived active ingredients

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Since the early 1960s, nanotechnology has been a critical area of science, allowing for the development of sophisticated nanomaterials. Nanofibers, one of the most widely used nanotechnological drug delivery systems, have emerged as a highly versatile platform within modern pharmaceutical sciences.

Disclosing the production of fungal chitinases and proteases using insect by‐products as substrates in solid‐state fermentation

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The world population is projected to reach nearly 9.7 billion by 2050, significantly increasing the demand for novel and sustainable protein sources. Edible insects, such as Tenebrio molitor, emerge as promising alternatives due to their high nutritional value, but adult insects and frass are direct and abundant by‐products of this ...

Environmental Filtering and Microbial Interactions Drive Soil Bacterial and Fungal Community Assembly in Subtropical Forests

Land Degradation &Development, EarlyView.
ABSTRACT Soil microbial communities are pivotal to forest ecosystem functions, yet the mechanisms shaping their assembly across complex environments remain poorly understood. This study examined bacterial and fungal communities within topsoil and subsoil under subtropical coniferous forest (CF), mixed conifer–broadleaf forest (MF), and broadleaf forest

Chitin Synthase Is Critical for Epidermal Chitin Deposition and Molting in the Swimming Crab Portunus trituberculatus

Fishes
Chitin synthase (CHS) catalyzes the final polymerization step in chitin biosynthesis and is therefore central to cuticle formation in arthropods. In this study, a chitin synthase gene from the swimming crab Portunus trituberculatus (PtCHS) was identified

Root Order Dependent Changes in Fine‐Root Substrate and Soil Environment Regulate Soil Organic Nitrogen Fractions Under Acid Rain and Nitrogen Deposition

Land Degradation &Development, EarlyView.
ABSTRACT Acid rain and nitrogen deposition are important environmental stressors affecting soil nitrogen cycling in subtropical forests, whereas fine‐root decomposition represents a major pathway for soil organic nitrogen (SON) input and transformation.

Water Table Decline Shifts Microbial Necromass From Particulate to Mineral‐Associated Pools in Peatlands

Land Degradation &Development, EarlyView.
ABSTRACT Microbial necromass carbon (MNC) is a major and stable component of soil organic carbon, yet its fraction‐specific accumulation and stabilization mechanisms remain unclear, particularly in peatlands experiencing hydrological change. We investigated MNC distribution along three independent transects spanning a natural gradient of five ...

Redefining CHI3L1: Therapeutic Opportunities at the Crossroads of Immune Suppression and Disease Progression

Medicinal Research Reviews, EarlyView.
ABSTRACT Chitinase‐3‐like‐1 (CHI3L1, also known as YKL‐40) has been recognized as a biomarker of inflammation and tissue remodeling and has now emerged as a pseudoenzymatic immune checkpoint. Recent structural, immunological, and translational studies redefine it as an active regulator of immune suppression rather than a passive disease marker. Despite

Composite Fibers of Hydroxypropyl Cellulose and Alginate Spun From Aqueous Solution: Crosslinking Effects on Water Absorption and Mechanical Properties

Polymer Engineering &Science, EarlyView.
Alginate‐HPC composite fibers spun via CaCl2‐induced gelation process. Fiber diameter ranges from 100 to 200 μm after air drying. Higher alginate boosts water absorption in dried fibers. HPC selectively diffuses out when fibers are soaked in water. Crosslinking with hexamethylene diisocyanate improves mechanical strength.
