Assessing the spatial scale of synchrony in forest tree population dynamics.

Populations of forest trees exhibit large temporal fluctuations, but little is known about the synchrony of these fluctuations across space, including their sign, magnitude, causes and characteristic scales. These have important implications for metapopulation persistence and theoretical community ecology. Using data from permanent forest plots spanning local, regional and global spatial scales, we measured spatial synchrony in tree population growth rates over sub-decadal and decadal timescales and explored the relationship of synchrony to geographical distance.

Plant-produced SARS-CoV-2 antibody engineered towards enhanced potency and in vivo efficacy.

Prevention of severe COVID-19 disease by SARS-CoV-2 in high-risk patients, such as immuno-compromised individuals, can be achieved by administration of antibody prophylaxis, but producing antibodies can be costly. Plant expression platforms allow substantial lower production costs compared to traditional bio-manufacturing platforms depending on mammalian cells in bioreactors. In this study, we describe the expression, production and purification of the originally human COVA2-15 antibody in plants.

The significance of social interactions in synchronized swarming flight in a termite.

In social insects, individuals of working caste coordinate their actions to manage various collective tasks. Such collective behaviours exist not only in workers but also in winged reproductives (alates). During certain seasons, newly emerged alates fly from the nest to disperse and find mating partners in a synchronized manner.

The Aloe vera acemannan polysaccharides inhibit phthalate-induced cell viability, metastasis, and stemness in colorectal cancer cells.

Plasticizers are recognized as environmental pollutants that may be associated with a range of health concerns, including impacts on growth, development, and oncogenic risks. Previous research demonstrated that prolonged exposure to di-(2-ethylhexyl) phthalate and its metabolite mono-(2-ethylhexyl) phthalate contributes to chemotherapeutic drug resistance and stemness in colorectal cancer cells. Aloe vera, an herbaceous plant with a long-standing history in traditional medicine, has attracted considerable attention for its diverse pharmacological properties.

Integrative analysis of non12-hydroxylated bile acid revealed the suppressed molecular map of alternative pathway in nonalcoholic steatohepatitis mice.

Bile acids (BAs) are significantly altered in the liver and serum of patients with nonalcoholic steatohepatitis (NASH). However, the underlying mechanisms of these changes, particularly BA alternative pathways (BAP) responsible for non12-OH BAs, remain unclear. RNA-seq data were initially analyzed to reveal the changes of gene expression in NASH patients.

Dual activation of soybean resistance against Phytophthora sojae by pectin lyase and degraded pectin oligosaccharides.

Phytophthora pathogens secrete numerous apoplastic effectors to manipulate host immunity. Herein, we identified a polysaccharide lyase 1 protein, PsPL1, which acts as an essential virulence factor of P. sojae infection in soybean.

The impact of 9-azaglycophymine and phenylguanidine derivatives on the proliferation of various breast cancer cell lines in vitro and in vivo.

Quinazolinones, particularly 9-azaglycophymines, and closely related derivatives and precursors were tested in vitro against various breast cancer cell lines representing the major types of breast tumors. Among the 49 compounds tested, azaglycophymine derivative 19 with an electron-withdrawing substituent demonstrated the most significant anti-proliferative effects, with IC values of around 4 µM. Extensive cell-based investigations revealed that compound 19 induced caspase-dependent apoptosis in HCC1937 (human TNBC), BT-474 (human HER2+/HR+), and 4T1 (mouse TNBC) cells.

A single NLR gene confers resistance to leaf and stripe rust in wheat.

Nucleotide-binding leucine-rich repeat (NLR) disease resistance genes typically confer resistance against races of a single pathogen. Here, we report that Yr87/Lr85, an NLR gene from Aegilops sharonensis and Aegilops longissima, confers resistance against both P. striiformis tritici (Pst) and Puccinia triticina (Pt) that cause stripe and leaf rust, respectively.

Stilbene-enriched extract from the leaves of Cajanus cajan attenuates psoriasis in imiquimod-induced psoriatic mice by targeting aryl hydrocarbon receptor and chemokines.

Ethnopharmacological Relevance: The leaves of Cajanus cajan (L.) Millsp., an Asian traditional folkloric medicine, have been used to treat inflammatory conditions since ancient times.

Pulmonary delivery of dual-targeted nanoparticles improves tumor accumulation and cancer cell targeting by restricting macrophage interception in orthotopic lung tumors.

Despite the recognized potential of inhaled nanomedicines to enhance and sustain local drug concentrations for lung cancer treatment, the influence of macrophage uptake on targeted nanoparticle delivery to and within tumors remains unclear. Here, we developed three ligand-coated nanoparticles for pulmonary delivery in lung cancer therapy: phenylboronic acid-modified nanoparticles (PBA-NPs), PBA combined with folic acid (FA-PBA-NPs), and PBA with mannose (MAN-PBA-NPs). In vitro, MAN-PBA-NPs were preferentially internalized by macrophages, whereas FA-PBA-NPs exhibited superior uptake by cancer cells compared to macrophages.

Clerodendrum trichotomum Extract Attenuates UV-B-Induced Skin Impairment in Hairless Mice by Inhibiting MAPK Signaling.

Background: Exposure to solar ultraviolet-B (UV-B) radiation significantly accelerates skin aging by inducing the expression of matrix metalloproteinases (MMPs) such as MMP-1, leading to alterations in the extracellular matrix and consequent photoaging. Some plant components, renowned for their UV-absorbing and antioxidative properties, show potential for mitigating photoaging by reducing UV-B-induced MMP levels. In this context, we explored the inhibitory effects of Clerodendrum trichotomum extract (CTE) on UV-B-induced skin damage.

Unleashing the synergistic effect of promising fungicides: a breakthrough solution for combating powdery mildew in pea plants.

Pea powdery mildew, caused by , is a major limitation to global pea production. The emergence of fungicide-resistant pathogen populations due to frequent and injudicious pesticide application highlights the importance of exploring the synergistic properties of fungicide combinations. This study investigated the efficacy of difenoconazole, thiophanate-methyl, and sulfur, both individually and in mixtures, against powdery mildew and assessed the interaction types between these fungicides.

A small antimicrobial peptide derived from a Burkholderia bacterium exhibits a broad-spectrum and high inhibiting activities against crop diseases.

Crop diseases cause significant quality and yield losses to global crop products each year and are heavily controlled by chemicals along with very limited antibiotics composed of small molecules. However, these methods often result in environmental pollution and pest resistance, necessitating the development of new bio-controlling products to mitigate these hazards. To identify effective antimicrobial peptides (AMPs) considered as potential sources of future antibiotics, AMPs were screened from five bacterial strains showing antagonism against a representative phytopathogenic fungus (Rhizoctonia Solani) through the Bacillus subtilis expression system, which has been developed for identifying bacterial AMPs by displaying autolysis morphologies.

Cellular stress response and neuroprotection of flavonoids in neurodegenerative diseases: Clinical insights into targeted therapy and molecular signaling pathways.

Neurodegenerative diseases (NDs) are caused by the gradual decline of neuronal structure and function, which presents significant challenges in treatment. Cellular stress responses significantly impact the pathophysiology of these disorders, often exacerbating neuronal damage. Plant-derived flavonoids have demonstrated potential as neuroprotective agents due to their potent anti-inflammatory, anti-apoptotic, and antioxidant properties.
