Massive Burn Injuries: Characteristics and Outcomes From a Single Institution.

Massive burn injuries are a unique patient population with unique treatment paradigms. Data from 155 adult patients, admitted from 2009 to 2019, with >50% total body surface area burns (TBSA) were collected and analyzed. Average burn size was 70% TBSA and 63% had a concomitant inhalation injury.

A deficiency in SUMOylation activity disrupts multiple pathways leading to neural tube and heart defects in Xenopus embryos.

Background: Adenovirus protein, Gam1, triggers the proteolytic destruction of the E1 SUMO-activating enzyme. Microinjection of an empirically determined amount of Gam1 mRNA into one-cell Xenopus embryos can reduce SUMOylation activity to undetectable, but nonlethal, levels, enabling an examination of the role of this post-translational modification during early vertebrate development.

Results: We find that SUMOylation-deficient embryos consistently exhibit defects in neural tube and heart development.

T-cell number and subtype influence the disease course of primary chronic lymphocytic leukaemia xenografts in alymphoid mice.

Chronic lymphocytic leukaemia (CLL) cells require microenvironmental support for their proliferation. This can be recapitulated in highly immunocompromised hosts in the presence of T cells and other supporting cells. Current primary CLL xenograft models suffer from limited duration of tumour cell engraftment coupled with gradual T-cell outgrowth.

Immunogenicity and Serological Cross-Reactivity of Saliva Proteins among Different Tsetse Species.

Tsetse are vectors of pathogenic trypanosomes, agents of human and animal trypanosomiasis in Africa. Components of tsetse saliva (sialome) are introduced into the mammalian host bite site during the blood feeding process and are important for tsetse's ability to feed efficiently, but can also influence disease transmission and serve as biomarkers for host exposure. We compared the sialome components from four tsetse species in two subgenera: subgenus Morsitans: Glossina morsitans morsitans (Gmm) and Glossina pallidipes (Gpd), and subgenus Palpalis: Glossina palpalis gambiensis (Gpg) and Glossina fuscipes fuscipes (Gff), and evaluated their immunogenicity and serological cross reactivity by an immunoblot approach utilizing antibodies from experimental mice challenged with uninfected flies.

Bezafibrate and medroxyprogesterone acetate target resting and CD40L-stimulated primary marginal zone lymphoma and show promise in indolent B-cell non-Hodgkin lymphomas.

B cell non-Hodgkin lymphomas (B-NHLs) are the most common adult hematological cancers and many remain incurable. Development of chemotherapy regimens is confounded by the prevalence of B-NHL in older, frailer patients and the chemo-protective tumor microenvironment. Although biological therapies such as rituximab have significantly improved outcomes and selective kinase inhibitors are showing promise, the rate of new drug discovery remains disappointing, the treatments expensive and long-term benefits uncertain.
