Endometriosis is a female-specific chronic condition that affects 1 in 10 women and other individuals with a uterus worldwide with common symptoms that include pelvic pain and infertility. Reliable and effective non-invasive biomarkers for endometriosis do not exist, and therefore currently a diagnosis of endometriosis requires direct visualization of lesions at surgery. Similarly, few safe and effective management strategies exist for endometriosis, with hormonal interventions and surgery only providing temporary symptom control.

Hodgkin Reed-Sternberg (HRS) cells of classic Hodgkin lymphoma (cHL), like many solid tumors, elicit ineffective immune responses. However, patients with cHL are highly responsive to PD-1 blockade, which largely depends on HRS cell-specific retention of MHC class II and implicates CD4 T cells and additional MHC class I-independent immune effectors. Here, we utilize single-cell RNA sequencing and spatial analysis to define shared circulating and microenvironmental features of the immune response to PD-1 blockade in cHL.

In the past decade, graphene-based nanomaterials (GBNs) have been considerably investigated in agriculture due to their exceptionally enriched physicochemical properties. Productivity in the agricultural sector relies significantly on agrochemicals. However, conventional systems suffer from a lack of application efficiency, resulting in environmental pollution and associated problems.

Notch1 and Notch2, transmembrane receptors belonging to the Notch family, are pivotal mediators of intercellular communication and have profound implications including cell fate determination, embryonic development, and tissue homeostasis in various cellular processes. Despite their structural homology, Notch1 and Notch2 exhibit discrete phenotypic characteristics and functional nuances that necessitate their individualized targeting in specific medical scenarios. Aberrant Notch signaling, often driven by the dysregulated activity of one receptor over the other, is implicated under various pathological conditions.

Hypertension, a key modifiable risk factor for cardiovascular diseases (CVD), significantly contributes to premature death and morbidity worldwide. Despite stabilization in age-adjusted global prevalence, the absolute number of hypertensive individuals doubled from 2000 to 2010, largely due to increases in low- and middle-income countries. In 2021, only 21% of hypertensive individuals globally had effective blood pressure (BP) control.

Follicular lymphoma (FL) is the second most common type of lymphoma (20% of all non-Hodgkin lymphomas), derived from germinal centre (GC) B cells, and is characterised by its significant clinical, prognostic and biological heterogeneity, leading to complexity in management. Despite significant biological investigation and indisputable clinical progress since the advent of the immunotherapy era more than 20 years ago, much remains to be done to understand and cure this lymphoma. Today, FL is metaphorically a giant puzzle on the table with patches of sky, landscape and foliage clearly appearing.

Article Synopsis
  • * The disease is difficult to control due to its wide assortment of host plants and the absence of rice cultivars that are resistant to the fungus.
  • * Modern solutions like advanced breeding techniques, CRISPR/Cas9 gene editing, and nanotechnology are being investigated to create rice plants that can resist sheath blight, as traditional methods have not been effective.

Porous materials are highly explored platforms for fertilizer delivery. Among porous materials, metal-organic frameworks (MOFs) are an important class of coordination polymers in which metal ions and organic electron donors as linkers are assembled to form crystalline structures with stable nanoporosity. Selected amino acids were inherently found to have the capacity to hold the leaf cuticle.

A series of 16 novel prenylated chalcones () was synthesized by microwave-assisted green synthesis using 5-prenyloxy-2-hydroxyacetophenone and different benzaldehydes. Comparisons were also performed between the microwave and conventional methods in terms of the reaction times and yields of all compounds, where the reaction times in the microwave and conventional methods were 1-4 min and 12-48 h, respectively. The synthesized compounds were characterized using different spectroscopic techniques, including IR, H-NMR, C-NMR, and LC-HRMS.
