Anti-Bacterial and Anti-Dermatophytic Activity of Extracellular Secondary Metabolites of Streptomyces glaucescens NTSB-37 Isolated from Lichen Parmotrema perlatum (Huds.) M. Choisy in Kolli Hills, Tamil Nadu, India.

Lichen-associated endophytic Actinobacteria, particularly Streptomyces species, are recognized for their production of bioactive secondary metabolites with significant pharmaceutical potential. With the escalating prevalence of diseases, Streptomyces species are being investigated for its natural source of antimicrobial compounds for new antibiotics. This study focuses on the bioactive properties of secondary metabolites from lichen-associated endophytic Actinobacteria, focusing on Streptomyces glaucescens NTSB-37 isolated form lichen, Parmotrema perlatum (Huds.

An assessment of the influence of dentinal pretreatment with chlorhexidine, nonthermal atmospheric plasma, chitosan, and proanthocyanidins on shear bond strength to composite.

Context: Dentin biomodification has been emphasized as a means of improving the bond between composite resin and tooth surface, consequently enhancing its longevity.

Aim: To evaluate the shear bond strength (SBS) of dentin after pretreatment with 2% chlorhexidine (CHX), 2% chitosan, nonthermal atmospheric plasma (NTAP), proanthocyanidins (5% pine bark ((PB) and 5% bromelain).

Settings And Design: The study was designed as an investigation.

Effect of nonthermal atmospheric plasma application at different time intervals on the dentinal shear bond strength pretreated with 2% chlorhexidine as cavity disinfectant: An study.

Context: Effective use of nonthermal atmospheric plasma (NTAP) to strengthen adhesive-dentin interfacial bonding while disinfecting with chlorhexidine (CHX).

Aim: NTAP application at different time intervals on the dentinal shear bond strength (SBS) after pretreatment with 2% CHX as a cavity disinfectant.

Settings And Design: The design of the study was an study.

A cell state-specific metabolic vulnerability to GPX4-dependent ferroptosis in glioblastoma.

Glioma cells hijack developmental programs to control cell state. Here, we uncover a glioma cell state-specific metabolic liability that can be therapeutically targeted. To model cell conditions at brain tumor inception, we generated genetically engineered murine gliomas, with deletion of p53 alone (p53) or with constitutively active Notch signaling (N1IC), a pathway critical in controlling astrocyte differentiation during brain development.

Impact of Previous Surgery and/or Radiation Therapy on Endoscopic Reconstruction Outcomes.

Background And Objectives: The impact of prior local therapies, including radiation and surgery, on reconstruction outcomes after endonasal surgery is currently not well known. Reconstruction nuances in the preoperative setting merit further evaluation to avoid potential postoperative complications that can hinder overall tumor management and negatively impact patient outcome. We sought to determine whether prior treatments increase risk of reconstruction-related postoperative morbidity and to evaluate the effectiveness of our current treatment paradigm for skull base reconstruction.
