The structure of Toho1 β-lactamase in complex with penicillin reveals the role of Tyr105 in substrate recognition [PDF]

open access: yes, 2016
The role of the conserved residue Tyr105 in class A β-lactamases has been the subject of investigation using both structural studies and saturation mutagenesis.

Penicillin encephalopathy [PDF]

open access: yesPostgraduate Medical Journal, 1968
Summary Five patients who developed characteristic myoclonic twitching, drowsiness and convulsions due to intravenous penicillin and cloxacillin are described. Three had poor renal function. Twenty-three reported cases of penicillin encephalopathy are reviewed and the aetiology of the syndrome is discussed.

Phenotypic and genotypic characterization of single circulating tumor cells in the follow‐up of high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Single circulating tumor cells (sCTCs) from high‐grade serous ovarian cancer patients were enriched, imaged, and genomically profiled using WGA and NGS at different time points during treatment. sCTCs revealed enrichment of alterations in Chromosomes 2, 7, and 12 as well as persistent or emerging oncogenic CNAs, supporting sCTC identity.

Impact of a Pharmacist-Driven Penicillin Allergy De-Labeling Pilot Program in Preoperative Cardiothoracic and Spine Surgery Patients at a Quaternary Hospital

open access: yesAllergies
Documented penicillin allergies are associated with an increased risk of surgical site infections (SSIs), and first-line antibiotics (e.g., cefazolin) are associated with a lower risk of SSIs.

Comparison of susceptibility test methods to detect penicillin susceptibility in Streptococcus pneumoniae isolates [PDF]

open access: yes, 2004
The increasing prevalence of penicillin-resistant Streptococuus pneumoniae urges for fast and accurate susceptibility testing methods. This study evaluated the comparability of three commonly used techniques; disk diffusion, E-test and agar dilution, to ...

Impact of antibiotics on the proliferation and differentiation of human adipose-derived mesenchymal stem cells [PDF]

open access: yes, 2017
Adipose tissue is a promising source of mesenchymal stem cells. Their potential to differentiate and regenerate other types of tissues may be affected by several factors. This may be due to in vitro cell-culture conditions, especially the supplementation

Combining antibody conjugates with cytotoxic and immune‐stimulating payloads maximizes anti‐cancer activity

open access: yesMolecular Oncology, EarlyView.
Methods to improve antibody–drug conjugate (ADC) treatment durability in cancer therapy are needed. We utilized ADCs and immune‐stimulating antibody conjugates (ISACs), which are made from two non‐competitive antibodies, to enhance the entry of toxic payloads into cancer cells and deliver immunostimulatory agents into immune cells.

Dammarenediol II enhances etoposide‐induced apoptosis by targeting O‐GlcNAc transferase and Akt/GSK3β/mTOR signaling in liver cancer

open access: yesMolecular Oncology, EarlyView.
Etoposide induces DNA damage, activating p53‐dependent apoptosis via caspase‐3/7, which cleaves PARP1. Dammarenediol II enhances this apoptotic pathway by suppressing O‐GlcNAc transferase activity, further decreasing O‐GlcNAcylation. The reduction in O‐GlcNAc levels boosts p53‐driven apoptosis and influences the Akt/GSK3β/mTOR signaling pathway ...
