Pectinase production by Aspergillus flavus was determined by measuring clear zones formed around colonies stained with ruthenium red. Several isolates produced red zones instead of clear zones. Red zones were reproduced with pectinesterase and correlated with absence of specific polygalacturonases. Of 87 isolates tested, 15 produced red zones.

Metal halides are widely applied in solid-state lighting (SSL), optoelectronic devices, information encryption, and near-infrared (NIR) detection due to their superior photoelectric properties and tunable emission. However, single-component phosphors that can be efficiently excited by light-emitting diode (LED) chips and cover both the visible (VIS) and NIR emission regions are still very rare. To address this issue, (TPA)ZnBr:Sn/Mn (TPA = [(CHCHCH)N]) phosphors were synthesized by using the solvent evaporation method.

Background: On April 15th, 2023, intense clashes involving heavy weapons and airstrikes occurred between the Sudanese Armed Forces (SAF) and the paramilitary Rapid Support Forces (RSF) in Khartoum, the capital of Sudan, leading to the displacement of almost 8.1 million people. The ongoing armed conflict in Sudan has led to a worsening humanitarian catastrophe, posing serious challenges to the country's health-care system and even its collapse.

Background: The evolving nature of irregular warfare and the increasingly frequent violations of human rights law and international humanitarian law pose unique challenges for humanitarian actors delivering trauma care in conflict settings.
Methods: A scoping review was conducted on PubMed, Scopus, and Web of Science and a web search (on Google, Google scholar and Bing) to analyze and review past humanitarian interventions offering trauma care in conflict settings. Relevant records were identified from scientific and grey literature.

Background: Dental root canal failure is a disease caused by gram-positive bacteria, Enterococcus faecalis. The disease is caused by the bacterial cell wall consisting of a peptidoglycan layer that protects the bacteria from internal osmotic pressure. Peptidoglycan biosynthesis includes many enzymes, such as MurA, Penicillin-binding protein (PBP), and SrtA.

Mitophagy that disrupt mitochondrial membrane potential (MMP), represents a critical focus in pharmacology. However, the discovery and evaluation of MMP-disrupting drugs are often hampered using commercially available marker molecules that target similar or identical zones. These markers can significantly interfere with, obscure, or amplify the functional effects of MMP-targeting drugs, frequently leading to clinical failures.
