Transcriptome-Wide Association Study Identified Novel Blood Tissue Gene Biomarkers for Prostate Cancer Risk.

Objective: A number of susceptibility genes in prostate tissue have been identified to be associated with prostate cancer (PCa) risk. However, the reported genes based on assessing prostate tissue could not fully explain PCa genetic susceptibility. It is believed that genes functioning in the immune system may fill in the gap of some missing heritability.

Development, validation, and reliability testing of the College Perspectives around Food Insecurity survey.

The objective of this study was to develop and to test the validity and reliability of a survey aimed to evaluate internal and external factors associated with college food insecurity. Researchers used a mixed methods approach to evaluate the College Perspectives around Food Insecurity survey. Survey items were constructed from interview data and assigned a social cognitive theory concept (environment, personal, or behavior).

Drought as an emergent driver of ecological transformation in the twenty-first century.

Under climate change, ecosystems are experiencing novel drought regimes, often in combination with stressors that reduce resilience and amplify drought's impacts. Consequently, drought appears increasingly likely to push systems beyond important physiological and ecological thresholds, resulting in substantial changes in ecosystem characteristics persisting long after drought ends (i.e.

New evidence for early Indian Ocean trade routes into the South African interior.

The rise and spread of ancient Indian Ocean Rim (IOR) trade networks profoundly impacted southern Africa. Control over this trade played a critical role in the rise and maintenance of complex societies of the second millennium CE such as Mapungubwe and Great Zimbabwe. While the African origins of this trade lie in the first millennium CE, understanding its earliest phases and subsequent development in the far south has been hampered by a general paucity of research.

The Changing pathogenesis of liver cancer in Hawaii over three decades.

Background: Worldwide trends support the increasing contribution of hepatic steatosis on the incidence of hepatocellular carcinoma (HCC). This study investigates if similar changes are seen in Hawaii, where the incidence of HCC is higher than most of the United States. Methods; This is a retrospective study of 1651 patients diagnosed with HCC (1991-2023) that includes 60-70% of Hawaii's HCC cases.

Extracellular Regucalcin: A Potent Suppressor in the Cancer Cell Microenvironment.

The regucalcin gene is located on the X chromosome, comprising seven exons and six introns. This gene and protein are expressed in various tissues and cells and is predominantly expressed in human liver, kidney, and adrenal tissues. Regucalcin gene expression is enhanced via a mechanism mediated by several signaling molecules and transcription factors.

Elderhood and Healthy Aging from an Indigenous Perspective.

Researchers have outlined the components of healthy aging, and a 2022 scoping review by Quigley et al. examined healthy aging from Indigenous perspectives. Quigley's review reinforced the notion that Indigenous health, and thus healthy aging, is a holistic concept.

Diabetes Management Using a Patient Navigator in a Native Hawaiian Population: Experiences and Perceptions of the Kilolani Project.

Native Hawaiians (NHs) are a historically oppressed population disproportionately burdened by diabetes and related complications. The Kilolani Project, a patient navigator-centered, chronic disease management program, targets upstream drivers of health among vulnerable NH adult patients with diabetes within an urban academic safety-net clinic. To investigate the impact of the Kilolani Project, we performed a qualitative study to examine patient perspectives.

Agricultural Landscape Genomics to Increase Crop Resilience.

Populations are continually adapting to their environment. Knowledge of which populations and individuals harbor unique and agriculturally useful variation has the potential to accelerate crop adaptation to the increasingly challenging environments predicted for the coming century. Landscape genomics, which identifies associations between environmental and genomic variation, provides a means for obtaining this knowledge.

Photocatalytic Three-Component Reductive Coupling Synthesis of -Difluorohomoallyl Secondary Amines.

-Difluorohomoallyl amines, an important class of -difluoroalkenes, are prevalent moieties in many bioactive compounds. However, limited methods are suitable for the synthesis of this type of compound containing secondary amines. Here, we display a photocatalytic multicomponent protocol for the synthesis of -difluoroalkenes containing secondary amines, which makes use of readily available materials: arylamines, alkyl aldehydes, and α-trifluoromethyl alkenes.

Marine heatwaves imperil emblematic reef fishes by altering the energetic landscape of coral reefs.

Marine heatwaves are increasingly common due to human-induced climate change. Under prolonged thermal stress on coral reefs, corals can undergo bleaching, leading to mass coral mortality and large-scale changes in benthic community composition. While coral mortality has clear, negative impacts on the body condition and populations of coral-dependent fish species, the mechanisms that drive these changes remain poorly resolved.

Submarine groundwater discharge drives both direct and indirect effects on organismal and community metabolism on coral reefs.

Coral reefs experience numerous environmental gradients affecting organismal physiology and species biodiversity, which ultimately impact community metabolism. This study shows that submarine groundwater discharge (SGD), a common natural environmental gradient in coastal ecosystems associated with decreasing temperatures, salinity and pH with increasing nutrients, has both direct and indirect effects on coral reef community metabolism by altering individual growth rates and community composition. Our data revealed that SGD exposure hindered the growth of two algae, and by 67 and 200%, respectively, and one coral, by 20%.

Digestion of food proteins: the role of pepsin.

The nutritive value of a protein is determined not only by its amino acid composition, but also by its digestibility in the gastrointestinal tract. The interaction between proteins and pepsin in the gastric stage is the first step and plays an important role in protein hydrolysis. Moreover, it affects the amino acid release rates and the allergenicity of the proteins.

Effect of oscillating magnetic field (OMF) on the supercooling behavior of iron-oxide nanoparticle (IONP) agar model system.

Freezing extends the shelf life of foods but often leads to structural damage due to ice crystal formation, negatively impacting quality attributes. Oscillating magnetic field (OMF)-assisted supercooling has emerged as a potential technique to overcome these limitations by inhibiting ice nucleation and maintaining foods in a supercooled state. Despite its potential, the effectiveness and underlying mechanisms of OMF-assisted supercooling remain subjects of debate.

Development and Implementation of a Minority Health International Infectious Diseases Research Training Program.

From 2014-2019, the University of Hawai'i (UH) at Manoa offered a National Institutes of Health funded Minority Health International Research Training (MHIRT) Program for undergraduate research experiences in infectious diseases. The goal of the program was to immerse undergraduate students in conducting global infectious diseases research to train a new generation of scientists to combat future global pandemics. The MHIRT program trained educationally underrepresented groups unique in Hawai'i: Native Hawai'ians and other Pacific Islanders, and underrepresented Asian Americans, e.

Diversity, connectivity and negative interactions define robust microbiome networks across land, stream, and sea.

In this era of rapid global change, factors influencing the stability of ecosystems and their functions have come into the spotlight. For decades the relationship between stability and complexity has been investigated in modeled and empirical systems, yet results remain largely context dependent. To overcome this we leverage a multiscale inventory of fungi and bacteria ranging from single sites along an environmental gradient, to habitats inclusive of land, sea and stream, to an entire watershed.

Analysis of cellular NO-GC expression in the murine heart and lineage determination in angiotensin II-induced fibrosis.

NO-sensitive guanylyl cyclase (NO-GC) is involved in the (patho)physiology of the mammalian heart. However, little is known about the individual cardiac cell types that express NO-GC and the role of the enzyme in cardiac fibrosis. Here, we describe the cellular expression of NO-GC in healthy and fibrotic murine myocardium; these data were compared with scRNA-seq data.

Symbiotic fungi alter plant resource allocation independent of water availability.

Premise: The ability of plants to adapt or acclimate to climate change is inherently linked to their interactions with symbiotic microbes, notably fungi. However, it is unclear whether fungal symbionts from different climates have different impacts on the outcome of plant-fungal interactions, especially under environmental stress.

Methods: We tested three provenances of fungal inoculum (originating from dry, moderate or wet environments) with one host plant genotype exposed to three soil moisture regimes (low, moderate and high).

Progressive anterior segment involvement of an infant with corneoscleral juvenile xanthogranuloma refractory to topical steroids.

Purpose: To report a case of corneoscleral juvenile xanthogranuloma (JXG) with progressive anterior segment involvement refractory to topical steroids.

Observations: A 4-month-old male was referred for a new-onset subconjunctival lesion in the right eye. He was found to have a thickened, yellow corneoscleral lesion and hyphema, presumed to be ocular JXG.

From forests to farming: identification of photosynthetic limitations in breadfruit across diverse environments.

Breadfruit (Artocarpus altilis) is a prolific tropical tree producing highly nutritious and voluminous carbohydrate-rich fruits. Already recognized as an underutilized crop, breadfruit could ameliorate food insecurity and protect against climate-related productivity shocks in undernourished equatorial regions. However, a lack of fundamental knowledge impedes widespread agricultural adoption, from modern agroforestry to plantation schemes.

Environmental controls on the conversion of nutrients to chlorophyll in lakes.

Anthropogenic inputs of nitrogen and phosphorus to lakes have increased worldwide, causing phytoplankton chlorophyll concentrations to increase at many sites, with negative implications for biodiversity and human usage of lake resources. However, the conversion of nutrients to chlorophyll varies among lakes, hindering effective management actions to improve water quality. Here, using a rich global dataset, we explore how the relationship between chlorophyll-a (Chla) and nitrogen and phosphorus and inferred nutrient limitation is modified by climate, catchment, hydrology and lake characteristics.

Predicting Chlorophyll- Concentrations in the World's Largest Lakes Using Kolmogorov-Arnold Networks.

Accurate prediction of chlorophyll- (Chl-) concentrations, a key indicator of eutrophication, is essential for the sustainable management of lake ecosystems. This study evaluated the performance of Kolmogorov-Arnold Networks (KANs) along with three neural network models (MLP-NN, LSTM, and GRU) and three traditional machine learning tools (RF, SVR, and GPR) for predicting time-series Chl- concentrations in large lakes. Monthly remote-sensed Chl- data derived from Aqua-MODIS spanning September 2002 to April 2024 were used.

Continental influx and pervasive matrilocality in Iron Age Britain.

Roman writers found the relative empowerment of Celtic women remarkable. In southern Britain, the Late Iron Age Durotriges tribe often buried women with substantial grave goods. Here we analyse 57 ancient genomes from Durotrigian burial sites and find an extended kin group centred around a single maternal lineage, with unrelated (presumably inward migrating) burials being predominantly male.
