Typical late embryogenesis abundant (LEA) proteins accumulate in response to water deficit imposed by the environment or by plant developmental programs. Because of their physicochemical properties, they can be considered as hydrophilins and as a paradigm of intrinsically unstructured proteins (IUPs) in plants. To study their biophysical and biochemical characteristics large quantities of highly purified protein are required. In this work, we report a fast and simple purification method for non-acidic recombinant LEA proteins that does not need the addition of tags and that preserves their in vitro protective activity. The method is based on the enrichment of the protein of interest by boiling the bacterial protein extract, followed by a differential precipitation with trichloroacetic acid (TCA). Using this procedure we have obtained highly pure recombinant LEA proteins of groups 1, 3, and 4 and one recombinant bacterial hydrophilin. This protocol will facilitate the purification of this type of IUPs, and could be particularly useful in proteomic projects/analyses.

() genes play a crucial role in the response to abiotic stress and are important target genes for research on plant stress tolerance mechanisms. Bunge is a promising candidate tree species for investigating the tolerance mechanism of woody plants against abiotic stress. In our previous study, was identified as being associated with seed drought tolerance.

We aim to understand the host immunologic and microbial features of COVID-19 in transplant recipients by leveraging a prospective multicenter cohort of 86 transplant recipients age- and sex-matched with 172 non-transplant controls. We find that transplant recipients have higher nasal SARS-CoV-2 viral abundance and impaired viral clearance, and lower anti-spike IgG levels.

Background: Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease, associated with MEFV mutations. FMF patients can experience liver involvement, potentially leading to cirrhosis.
Objectives: This study aimed to evaluate liver involvement in FMF patients at a French tertiary centre for adult FMF.

Aim: Hypothyroidism is created by disruption of thyroid hormone production, which can destroy the emotional, relational, social, and working life of patients if left untreated. Hypothyroidism has multiple etiologies. We evaluated the relationship of hematological parameters and inflammatory biomarkers with thyroid hormones to find the potential use of these items in patients screening and prognosis.
