The importance of amyloid nanofibrils made from food proteins is rising in diverse fields, such as biomedicine and food science. These protein nanofibrils (PNFs) serve as versatile and sustainable building blocks for biomaterials, characterized by their high β-sheet content and an ordered hydrogen bond network. These properties offer both stability and flexibility, along with an extreme aspect ratio and reactive functional groups.

Background And Aims: Scar tissue accumulation in organs is the underlying cause of many fibrotic diseases. Due to the extensive array of organs affected, the long-term nature of fibrotic processes and the large number of people who suffer from the negative impact of these diseases, they constitute a serious health problem for modern medicine and a huge economic burden on society. Sodium-glucose cotransporter-2 inhibitors (SGLT2is) are a relatively new class of anti-diabetic pharmaceuticals that offer additional benefits over and above their glucose-lowering properties; these medications modulate a variety of diseases, including fibrosis.

The main factor leading to a decrease in crop productivity is abiotic stresses, particularly drought. Plants with C4 and CAM photosynthesis are better adapted to drought-prone areas than C3 plants. Therefore, it is beneficial to compare the stress response of plants with different photosynthetic pathways.

Background: Several studies have reported a possible association of miR-146a rs2910164 polymorphism with Breast Cancer (BC) development. However, the correlation between this polymorphism and susceptibility to BC is under debate. The current meta-analysis was designed and performed to more conclusively evaluate the miR-146a rs2910164 polymorphism and its potential link to BC.

Introduction: MicroRNAs (miRNAs) play an essential role in the susceptibility and development of cancer cells.

Objective: Examining the dependency of breast cancer risk with genetic polymorphisms of miR-1307, miR-1269, and miR-3117 in a sample of Iranian women (southeast region).

Methods: The case-control study consisted of 520 individuals (260 diagnosed BC patients, 260 healthy individuals).

Article Synopsis
  • PD-1 and its ligands (PD-L1, PD-L2) are key regulators of immune cells, influencing T cells and other immune responses.
  • The study examined the relationship between specific genetic variants of PD-1 and PD-L1 and the risk of breast cancer in southeast Iranian women, involving 520 participants (260 cancer patients and 260 healthy controls).
  • Results indicated that the PD-L1 rs4143815 variant decreased breast cancer risk, while rs2890658 increased risk; however, PD-1 variants did not show a significant association with breast cancer.
  • Further analysis linked certain PD-1 and PD-L1 variants to patient age and tumor characteristics, such as size and grade.

Fibroblast growth factor receptor 4 (FGFR4) is a cell surface receptor tyrosine kinases (RTKs) for FGFs. Several studies have focused on the association between FGFR4 polymorphisms and cancer development. This meta-analysis aimed to estimate the association between FGFR4 rs351855 (Gly388Arg), rs1966265 (Val10Ile), rs7708357, rs2011077, and rs376618 polymorphisms and cancer risk.

Several recent investigations show that HOX transcript antisense intergenic RNA () play an important role in the pathogenesis of different cancers. polymorphisms has been widely studied in the context of association between with the risk of cancer pathogenesis. However, there is no certain conclusion about the role of polymorphisms in different cancer initiation and progression.

Neuroblastoma (NB), a neuroendocrine tumour, is one of the most prevalent cancers in children. The link between LMO1 polymorphisms and NB has been investigated by several groups, rendering inconclusive results. Here, with this comprehensive systematic review and up-to-date meta-analysis, we aim to distinctively elucidate the possible correlation between LMO1 polymorphisms and NB susceptibility.

Long noncoding RNA (lncRNA) H19, a well-known oncogenic lncRNA, is overexpressed in various cancers. Several studies have investigated the association between polymorphisms in lncRNA H19 and the risk of various cancer types; however, the findings were inconsistent. In this study, we performed a meta-analysis to identify the precise association between H19 polymorphisms and cancer risk.

A number of case-control studies regarding the association of the polymorphisms in the programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) genes with the risk of cancer have yielded inconsistent findings. Therefore, we have conducted a comprehensive, updated meta-analysis study to identify the impact of and polymorphisms on overall cancer susceptibility. The findings revealed that rs2227981 and rs11568821 polymorphisms significantly decreased the overall cancer risk (Odds Ratio (OR) = 0.

Background: Resistance of bacteria against antibiotics and antimicrobials is arising worldwide and there is an urgent need for strategies that are capable of inactivating biofilm-state pathogens with less potential of developing resistance in pathogens. A promising approach could be photodynamic inactivation (PDI) which uses light in combination with a photosensitizer to induce a phototoxic reaction. In this study, we evaluated the in vitro phototoxic effect of hypericin (HYP) alone and in combination with acetylcysteine (AC) on Staphylococcus aureus biofilms.
