Sus1 Modulates Chromatin Remodeling and Gene Expression via the Cell Wall Integrity Pathway in Saccharomyces cerevisiae

open access: yesThe FASEB Journal, Volume 40, Issue 9, 15 May 2026.
Cell wall stress in yeast triggers transcriptional reprogramming through the CWI pathway. This study identifies Sus1, a subunit of SAGA and TREX‐2, as a key regulator in this process. Sus1 associates with stress‐responsive genes, promoting pre‐initiation complex assembly, chromatin remodeling, and RNA Pol II progression independently of H2B ...

Application of Torrefaction for Improved Fuel Properties of Sunflower Husks

open access: yesEnergies
Sunflower husk (SFH) contributes 45–60% of the total sunflower seed weight and is a by-product of the sunflower oil industry. Among other elements, SFH ash contains K, Na, Ca and Mg. These elements cause rapid growth of ash deposits on convective heating

Management practices in community-based HIV prevention organizations in Nigeria

open access: yesBMC Health Services Research, 2021
Background Nigeria has one of the largest Human Immunodeficiency Virus (HIV) epidemics in the world. Addressing the epidemic of HIV in such a high-burden country has necessitated responses of a multidimensional nature.

Measuring Galaxy Star Formation Rates From Integrated Photometry: Insights from Color-Magnitude Diagrams of Resolved Stars

open access: yes, 2013
We use empirical star formation histories (SFHs), measured from HST-based resolved star color-magnitude diagrams, as input into population synthesis codes to model the broadband spectral energy distributions (SEDs) of ~50 nearby dwarf galaxies (6.5 < log

Evaluating Inflammatory Gene Expression Linked to Chronic Obstructive Pulmonary Disease in Workers of the Nanoparticle Industries: A Cross‐Sectional Study

open access: yesHealth Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background Nanoparticles (NPs) are increasingly used in industry for their unique properties. However, prolonged occupational exposure to common NPs like titanium dioxide (TiO₂), zinc oxide (ZnO), silver (Ag), and silica (SiO₂) may trigger systemic inflammation and contribute to chronic obstructive pulmonary disease (COPD).

Fingerprinting Hysteresis

open access: yes, 2004
We test the predictive power of first-oder reversal curve (FORC) diagrams using simulations of random magnets. In particular, we compute a histogram of the switching fields of the underlying microscopic switching units along the major hysteresis loop ...

Occupational Exposure to UPVC Powder Containing Calcium Carbonate (CaCO3) Nanoparticles: A Cross‐Sectional Biological Monitoring and Qualitative Risk Assessment

open access: yesHealth Science Reports, Volume 9, Issue 5, May 2026.
ABSTRACT Background and Aims Nanomaterials are widely produced and used due to their unique physicochemical properties. Adding nano calcium carbonate to Unplasticized PolyVinyl Chloride (UPVC) improves durability and sustainability. Studies have shown that occupational exposure to UPVC powder can affect the health of employees.

Role of ZNF652 in Regulating Hepatocellular Carcinoma Cell Proliferation and Apoptosis via the circRHOT1/SLC38A6 Axis

open access: yesThe Kaohsiung Journal of Medical Sciences, Volume 42, Issue 5, May 2026.
ABSTRACT Hepatocellular carcinoma (HCC) is a heterogeneous malignancy characterized by high mortality rates. This article presents a discussion of the role of ZNF652 in HCC cell proliferation and apoptosis, thereby identifying a new target for HCC treatment. The expression levels of ZNF652, circRHOT1, and SLC38A6 in HCC and healthy cells were analyzed.

Correlation of the rate of Type Ia supernovae with the parent galaxy properties: Light and shadows [PDF]

open access: yes, 2019
The identification of the progenitors of Type Ia Supernovae (SNIa) is extremely important in several astrophysical contexts, ranging from stellar evolution in close binary systems to evaluating cosmological parameters. Determining the distribution of the

A new method to control the invasive sun corals (Tubastraea spp.): Underwater compressed‐air blasting

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
Underwater compressed‐air blasting is a novel method developed to control invasive sun corals (Tubastraea spp.). The technique removes coral soft tissue without fragmenting colonies, reducing the risk of regeneration and accidental spread. This approach offers a safer and practical tool for managing invasive corals in natural reefs and biofouling ...
