Role of the Water-Metal Ion Bridge in Quinolone Interactions with Gyrase.

Fluoroquinolones are an important class of antibacterials, and rising levels of resistance threaten their clinical efficacy. Gaining a more full understanding of their mechanism of action against their target enzymes-the bacterial type II topoisomerases gyrase and topoisomerase IV-may allow us to rationally design quinolone-based drugs that overcome resistance. As a step toward this goal, we investigated whether the water-metal ion bridge that has been found to mediate the major point of interaction between topoisomerase IV and topoisomerase IV and gyrase, as well as gyrase, exists in gyrase.

Geographic Distribution of Clinical Care for Transgender and Gender-Diverse Youth.

Objectives: Geographic barriers limit access to clinical care in the United States for transgender and gender-diverse (TGD) youth. Some factors differentiating access to care are variability in state laws/policies, the number of available clinical care programs and mental health providers for TGD youth.

Methods: We aggregated data from the Human Rights Campaign for pediatric clinical care programs for TGD youth, the Movement Advancement Project for state-by-state assessment of gender identity laws and policies, and Psychology Today for mental health providers for TGD youth by state.

Accuracy of online medical information: the case of social media in sickle cell disease.

The medical needs of individuals with sickle cell disease (SCD) are complex. Patients with SCD experience complications such as recurrent pain episodes and increased hospitalizations. Over 70% of AYA and their parents seek medical information from the Internet; 83% inquire on sites that have interactive/social features, such as Facebook or Twitter, yet accuracy remains unclear.

Baf45a Mediated Chromatin Remodeling Promotes Transcriptional Activation for Osteogenesis and Odontogenesis.

Chromatin remodeling, specifically the tissue-specific regulation in mineralized tissues, is an understudied avenue of gene regulation. Here we show that and , two homologs belong to ATPase-dependent SWI/SNF chromatin remodeling complex, preferentially expressed in osteoblasts and odontoblasts compared to and . Recently, biochemical studies revealed that BAF45A associates with Polybromo-associated BAF (PBAF) complex.
