Detecting Antibiotic Resistance in Strains of Selected Gram‐Negative Bacterial Species Using Raman Spectroscopy

Journal of Raman Spectroscopy, EarlyView.
Raman spectroscopy successfully identified antibiotic‐resistant Gram‐negative strains. Resistant strains of four bacterial species were discriminated from sensitive ones with 99.1% accuracy using PLS regression. The method allows for rapid, label‐free detection of antibiotic resistance.

Structural insights into urocanate reductase using room‐temperature X‐ray crystallography

Acta Crystallographica Section D, EarlyView.
The active‐site dynamics of the microbial enzyme urocanate reductase were revealed by room‐temperature X‐ray crystallography.Urocanate reductase (UrdA) is a bacterial enzyme that converts urocanic acid to imidazole propionate. Its catalytic residue Arg411 undergoes a large conformational change in the substrate‐bound versus product‐bound states.

Genetic and genomic approaches for the discovery of parasite genes involved in antimalarial drug resistance [PDF]

, 2013
The biggest threat to the war on malaria is the continued evolution of drug resistance by the parasite. Resistance to almost all currently available antimalarials now exists in Plasmodium falciparum which causes the most suffering among all human malaria

Pharmacological treatment with a GABA(A) receptor modulator and a selective serotonin reuptake inhibitor as a mitigation strategy against aircraft noise‐induced cardiovascular and neuronal damage

British Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Noise pollution, particularly by aircraft, is a significant risk factor for cardiovascular disease. Aircraft noise activates stress response pathways in the brain, via the amygdala, the sympathetic nervous system and the hypothalamic–pituitary–adrenal axis.

INHIBITORY ACTIVITY OF SOME MARINE SPONGE EXTRACTS FROM URABÁ GULF ON DIHYDROFOLATE REDUCTASE ENZYME

Vitae, 2009
Dihydrofolate reductase is an enzyme involved in the production of pyrimidinic base timidin, a structural component of DNA, therefore whatever substance that inhibit this enzyme inhibit the DNA synthesis as a consequence and it can be potentially useful ...

Structure-based design and synthesis of antiparasitic pyrrolopyrimidines targeting pteridine reductase 1 [PDF]

, 2014
The treatment of Human African Trypanosomiasis remains a major unmet health need in sub-Saharan Africa. Approaches involving new molecular targets are important and pteridine reductase 1 (PTR1), an enzyme that reduces dihydrobiopterin in Trypanosoma spp.

Caesarean Scar Ectopic Pregnancy: A Case Study

Sonography, Volume 13, Issue 2, June 2026.
ABSTRACT Caesarean scar ectopic pregnancy (CSEP) occurs when a blastocyst implants into the residual scar from a previous caesarean section delivery, in the anterior lower uterine segment. In this region the endometrium is thin or absent, and may represent a dehiscence of the mucosal margin of the myometrium, with implantation into the myometrium ...

Effect of Iron/Folic Acid Supplementation on the Outcome of Malaria Episodes Treated with Sulfadoxine-Pyrimethamine [PDF]

, 2014
Folic acid supplementation may potentially alter the efficacy of sulfadoxine-pyrimethamine (SP) treatment in children with malaria. However, there is lack of evidence fromrandomized controlled trials and effects of folic acid supplementation on clinical ...
