Antibiotic resistance of Staphylococcus aureus associated with subclinical and clinical mastitis in Uruguay during an eight-year period

Austral Journal of Veterinary Sciences, 2017
Records of in vitro susceptibility tests performed between 2008 and 2015 were retrospectively reviewed in order to evaluate the dynamic profiles of possible changes in antimicrobial resistance of Staphylococcus aureus isolated from milk samples of cows ...

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

FEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Penicillin allergy as an instrumental variable for estimating antibiotic effects on resistance

Nature Communications
Antibiotic resistance is influenced by prior antibiotic use, but precise causal estimates are limited. This study uses penicillin allergy as an instrumental variable (IV) to estimate the causal effect of antibiotics on resistance.

Peptidoglycan synthesis and penicillin resistance in Streptococcus pneumoniae [PDF]

, 2018
"Resistance to penicillin in Streptococcus pneumoniae involves remodelling of penicillin-binding proteins (PBPs), enzymes involved in the last stages of peptidoglycan (PGN) synthesis, which reduce the affinity of these targets to the

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

A reação em cadeia da polimerase na detecção da resistência à penicilina em Streptococcus pneumoniae Polymerase chain reaction used to detect Streptococcus pneumoniae resistance to penicillin

Jornal Brasileiro de Pneumologia, 2004
INTRODUÇÃO: O Streptococcus pneumoniae é o mais freqüente agente etiológico de infecções respiratórias adquiridas na comunidade e sua resistência aos antimicrobianos tem aumentado nos últimos anos. A determinação da resistência é feita rotineiramente por

Tissue cages in calves for studies on pharmacokinetic/pharmacodynamic relationships of antimicrobials [PDF]

, 2003
Knowledge on pharmacokinetic/pharmacodynamic (PK/PD) relationships of antimicrobials may assist in defining a dose that maximises effect while minimising side effects such as selection of resistance.
