Idiopathic pulmonary fibrosis (IPF) is a devastating interstitial lung disorder characterized by the accumulation of extracellular matrix and collagen, resulting in significant parenchymal scarring and respiratory failure that leads to mortality. Yohimbine (YBH) is an α-2 adrenergic receptor antagonist with anti-oxidant and anti-inflammatory properties. In the current study, we aimed to investigate the anti-inflammatory, anti-oxidant and anti-fibrotic activity of YBH against LPS/TGF-β-induced differentiation in BEAS-2B/LL29 cells and bleomycin (BLMN) induced pulmonary fibrosis model in rats.

Article Synopsis
  • Mycobacterium tuberculosis (Mtb) modifies its metabolism to thrive in host cells, focusing on the protein Rv0547c, which targets the mitochondria of host cells.
  • Rv0547c enhances mitochondrial membrane fluidity and respiratory capacity, independent of its predicted targeting sequence, by influencing lipid composition and fatty acid metabolism.
  • The study demonstrates that Rv0547c increases Mtb's persistence during macrophage infection and helps the bacteria survive under stressful conditions by optimizing mitochondrial functions.

Breast cancer is the second most frequent cancer among women. Out of various subtypes, triple-negative breast cancers (TNBCs) account for 15% of breast cancers and exhibit more aggressive characteristics as well as a worse prognosis due to their proclivity for metastatic progression and limited therapeutic strategies. It has been demonstrated that AMP-activated protein kinase (AMPK) has context-specific protumorigenic implications in breast cancer cells.

Article Synopsis
  • The text discusses how structural similarities in organic molecules lead to narcissistic self-sorted phenomena, enhancing exciton dissociation and charge separation in solar cells.
  • It presents two π-conjugated derivatives, one being a zinc-porphyrin linked to benzothiadiazole (PB) as the acceptor and anthracene (PA) as the donor, which form unique 1D nanofibers and aggregates.
  • The study highlights that the electrical properties of these self-sorting assemblies are influenced by the electrostatic potential differences between PA and PB, achieving a conductivity of 0.14 S cm, which aids in the development of more effective photovoltaic materials.

This study introduces a novel approach centered around the design and synthesis of an interfacial passivating layer in perovskite solar cells (PSCs). This architectural innovation is realized through the development of a specialized material, termed dithiafulvene end-capped Spiro[fluorene-9,9'-xanthene], denoted by the acronym AF32. In this design architecture, dithiafulvene is thoughtfully attached to the spiroxanthene fluorene core with phenothiazine as the spacer unit, possessing multiple alkyl chains.

Cerebral ischemic stroke is one of the foremost global causes of death and disability. Due to inadequate knowledge in its sequential disease mechanisms, therapeutic efforts to mitigate acute ischemia-induced brain injury are limited. Recent studies have implicated epigenetic mechanisms, mostly histone lysine acetylation/deacetylation, in ischemia-induced neural damage and death.

Silver nanoparticles (AgNPs) have been widely utilized in various biomedical and antimicrobial technologies, displaying broad-spectrum activities against Gram-negative and Gram-positive bacteria including multidrug-resistant strains. However, the emergence of resistance to AgNPs upon repeated exposure and the survival of bacteria after initial exposure to antimicrobial agents pose a threat, as they may lead to the development of new resistant populations. To combat the early stages of antibacterial resistance, systematic analysis is essential to understand the immediate response of bacteria to antimicrobial agents.

Control over the dimensionality of stimulated organic semiconductors has aroused significant interest in organic electronics; however, the design of such materials still remains to be decided. Herein, we have developed three dibenzothiophene-appended freebase, zinc-metalated and copper-metalated porphyrin derivatives (PFb-DBT, PZn-DBT and PCu-DBT) in which PCu-DBT leads to an anion-binding complex in chloroform upon the application of light, resulting in self-assembled 1D nanostructures with high electrical conductivity. Nevertheless, light-stimulated freebase and zinc-metalated P-DBT undergo protonation and demetalation.

Understanding the molecular basis of sex differences in neural response to acute hypoxic insult has profound implications for the effective prevention and treatment of ischemic stroke. Global hypoxic-ischemic induced neural damage has been studied recently under well-controlled, non-invasive, reproducible conditions using a zebrafish model. Our earlier report on sex difference in global acute hypoxia-induced neural damage and recovery in zebrafish prompted us to conduct a comprehensive study on the mechanisms underlying the recovery.
