Ethnobiology! Until when will the colonialist legacy be reinforced?

In this essay, we will present arguments for a negative answer to the debate question: "Is publishing ethnobiology data respectful of Indigenous and Local Knowledge holders' rights?" We recognize that ethnobiological research has advanced in recognizing the rights of Indigenous Peoples and Local Communities (IPLC), but we believe that we still have a long way to go in deconstructing colonialism in ethnobiology. In order to be truly respectful, ethnobiologists need to collaborate with IPLC to achieve an ethical science with equity between knowledge systems, fostering the co-production of knowledge from an intercultural science perspective. This essay was written by a group of Brazilian scientists, both IPLC and non-IPLC, and reflects a perspective of the academic universe seen from the place we are, in this multicultural and imbalanced world.

The α-synuclein seed amplification assay: Interpreting a test of Parkinson's pathology.

The α-synuclein seed amplification assay (αSyn-SAA) sensitively detects Lewy pathology, the amyloid state of α-synuclein, in the cerebrospinal fluid (CSF) of patients with Parkinson's disease (PD). The αSyn-SAA harnesses the physics of seeding, whereby a superconcentrated solution of recombinant α-synuclein lowers the thermodynamic threshold (nucleation barrier) for aggregated α-synuclein to act as a nucleation catalyst ("seed") to trigger the precipitation (nucleation) of monomeric α-synuclein into pathology. This laboratory setup increases the signal for identifying a catalyst if one is present in the tissue examined.

Reducing hyperuricemic events with SGLT2 inhibitors: An updated systematic review with meta-regression.

Introduction: Although sodium-glucose cotransporter-2 inhibitors (SGLT2i) were shown to lower hyperuricemic events in patients with type 2 diabetes mellitus (T2DM), the extent of this effect in the general population is yet to be elucidated. We performed an updated systematic review and meta-analysis on a large sample of patients with and without T2DM to evaluate the influence of SGLT2i therapy on clinically relevant hyperuricemic events, defined as the composite of acute gout flare episodes, acute anti-gout management or urate-lowering therapy initiation. Furthermore, we conducted a multivariate meta-regression to assess the relationship between different covariates and the pooled effect size.
