TGF-β Signaling in Microglia: A Key Regulator of Development, Homeostasis and Reactivity.

Microglia, the resident immune cells of the central nervous system (CNS), are crucial for normal brain development and function. They become reactive in response to brain injury and disease, a process known as microglial reactivity. This reactivity, along with microglial homeostasis, is tightly regulated by the local microenvironment and interactions with surrounding cells.

RAFT solution polymerisation of bio-based γ-methyl-α-methylene-γ-butyrolactone monomer in DMSO and Cyrene.

Reversible addition fragmentation chain transfer (RAFT) solution polymerisation of the bio-based lactone monomer γ-methyl-α-methylene-γ-butyrolactone (γMeMBL) has been demonstrated in DMSO and Cyrene. RAFT control was evidenced by control over molecular weights, low disperisites, and kinetic evaluation. Purified P(γMeMBL) homopolymers exhibited high glass transition temperatures (206-221 °C) and excellent thermal stabilities.

Uropathogen antibiogram regional variations-Are Australian antimicrobial guidelines appropriate?

Objectives: The objectives of this study are as follows: to assess the uropathogen antibiogram at two tertiary hospitals in Victoria to look at the difference in susceptibility patterns, to assess whether national guideline recommendations were applicable and to assess the feasibility of local antibiogram analysis to guide development of hospital-specific guidelines for empirical treatment of urosepsis and for pre-operative prophylaxis for urological procedures.

Patients And Methods: All positive urine cultures analysed at Barwon Health and Monash Health, two tertiary hospitals in regional and metropolitan Victoria, Australia, respectively, between January 2019 and December 2020 were retrospectively identified. Data obtained included the organism cultured and their susceptibility profiles.
