Structural characterization of two γδ TCR/CD3 complexes.

The T-cell receptor (TCR)/CD3 complex plays an essential role in the immune response and is a key player in cancer immunotherapies. There are two classes of TCR/CD3 complexes, defined by their TCR chain usage (αβ or γδ). Recently reported structures have revealed the organization of the αβ TCR/CD3 complex, but similar studies regarding the γδ TCR/CD3 complex have lagged behind.

Anti-VEGF therapy for proliferative diabetic retinopathy in Kearns-Sayre syndrome.

Purpose: Multiple mitochondrial syndromes, such as Kearns-Sayre, involve the concurrence of diabetes mellitus and inherited pigmentary retinopathy. It is rare, however, for proliferative disease to develop in these patients as existing inner retinal dysfunction is thought to be protective.

Methods: To our knowledge this is the first description of proliferative diabetic retinopathy (PDR) in Kearns-Sayre syndrome.

A case documenting distinct natural history of multizonal outer retinopathy and retinal pigment epitheliopathy (MORR) with longitudinal multi-modal documentation of progression.

Purpose: To describe the clinical and imaging characteristics of the acute progressive phase of a recently proposed clinical entity, Multizonal Outer Retinopathy and Retinal Pigment Epitheliopathy (MORR), a variant of Acute Zonal Occult Outer Retinopathy (AZOOR).

Methods: Single observational case report.

Results: We present the case of a 49-year-old myopic female with progressive outer retinopathy most consistent with a diagnosis of MORR.

European Respiratory Society Research Seminar on Preventing Pediatric Asthma.

This report is a summary of the presentations given at the European Respiratory Society's Research Seminar on Asthma Prevention. The seminar reviewed both epidemiological and mechanistic studies and concluded that; (i) reducing exposure of pregnant women and children to air pollution will reduce incident asthma, (ii) there are promising data that both fish oil and a component of raw cow's milk prevent asthma, and (iii) modulating trained immunity by either mimicking helminth infection or oral and sublingual bacterial products is a promising area of research.

Growing practices and the use of potentially harmful chemical additives from a web survey of mainly small-scale cannabis growers in 18 countries.

Background: There is emerging recognition of the risks of harmful chemical pesticides, fertilizers and 'nutrients' by cannabis growers. One group of chemicals, Plant Growth Regulators (PGRs), many of which have been banned from food crops for decades, have been found unlisted in a number of fertilizers and supplements marketed at cannabis growers.

Methods: This paper predominately uses data from a 2020-21 convenience web survey of mainly small-scale, recent (last 5yrs) cannabis growers from 18 countries (n = 11,479).
