Biopharmaceuticals, monoclonal antibody (mAb)-based therapeutics in particular, have positively impacted millions of lives. MAbs and related therapeutics are highly desirable from a biopharmaceutical perspective as they are highly target specific and well tolerated within the human system. Nevertheless, several mAbs have been discontinued or withdrawn based either on their inability to demonstrate efficacy and/or due to adverse effects. Approved monoclonal antibodies and derived therapeutics have been associated with adverse effects such as immunogenicity, cytokine release syndrome, progressive multifocal leukoencephalopathy, intravascular haemolysis, cardiac arrhythmias, abnormal liver function, gastrointestinal perforation, bronchospasm, intraocular inflammation, urticaria, nephritis, neuropathy, birth defects, fever and cough to name a few...

RBCs undergo numerous changes during storage and stored RBCs may induce adverse effects, ultimately resulting in organ injury in transfusion recipients. We tested the hypothesis that the addition of SP to stored RBCs would improve the quality of the stored RBCs and mitigate liver injury after transfusion in a murine model. RBCs were harvested from C57BL/6J mice and stored for 14 days in CPDA-1 containing either a solution of SP in saline or saline alone. Haemolysis, the 24-hour posttransfusion recovery, the oxygen-carrying capacity, and the SOD activity of stored RBCs were evaluated...

BACKGROUND/OBJECTIVES: The safety of administering uncrossmatched, group O, cold-stored, whole blood (cWB) during civilian trauma resuscitation was evaluated. METHODS/MATERIALS: Male trauma patients with haemorrhage-induced hypotension who received leuko-reduced uncrossmatched group O+, low titer (<50) anti-A and -B, platelet-replete cWB during initial resuscitation were included. The biochemical markers of haemolysis (lactate dehydrogenase, total bilirubin, haptoglobin, creatinine, serum potassium) were measured on the day of cWB receipt (day 0), and over the next 2 days, reports of transfusion reactions and total blood product administration in first 24 h of admission were recorded...

Herein, we report the development of a unique architecture by chemically crosslinking the salicylic acid (SA) based poly (anhydride-ester) onto a biodegradable amine functionalized polycaprolactone (PCL), using lactic acid as a spacer. The ester and amide linkages in the SA-PCL polymer, synthesized through melt condensation, were confirmed by NMR and FT-IR spectroscopic techniques. The enzymatic and non-enzymatic hydrolytic degradation profile exhibited linear degradation kinetics over extended time period (>5 weeks)...

In the last few years, marine species have been investigated for the presence of natural products with anticancer activity. Using reversed phase chromatography, low molecular weight proteins were fractionated from the sea anemone Anemonia viridis. Four different fractions were evaluated for their cytotoxic activity by means of erythrocyte haemolysis test, MTS, and LDH assays. Finally, the antiproliferative activities of three of these fractions were studied on PC3, PLC/PRF/5, and A375 human cancer cell lines...

AIMS: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support stabilizes patients with cardiogenic shock. Despite improved oxygenation and peripheral circulation, LV unloading may be impeded due to the increased afterload, resulting in a failing static left ventricle and in high mortality. METHODS AND RESULTS: We describe for the first time a large series of patients treated with the combination of VA-ECMO and Impella(®) compared with patients with VA-ECMO only...

Background. Blood transfusion is a therapeutic procedure usually undertaken in patients with severe anaemia. In Ghana, severe anaemia is mostly due to malaria caused by severe Plasmodium falciparum infection, road traffic accidents, and haemoglobinopathy-induced acute haemolysis. Method. This cross-sectional study evaluated coinheritance of sickle cell haemoglobin variant and G6PD enzymopathy among individuals that donated blood at the Holy Trinity Hospital, Berekum, in the Brong-Ahafo Region, Ghana. Demographic data and other pertinent information were captured using questionnaire...

A case of undiagnosed pulmonary hypertension in a woman with mixed connective tissue disease presenting with microangiopathic haemolysis, thrombocytopenia and elevated liver enzymes imitating severe preeclampsia (HELLP syndrome) is described. Connective tissue disorders are associated with an increased prevalence of pulmonary hypertension. Maternal mortality rates with pulmonary hypertension in pregnancy are extremely high. All women with connective tissue disorders should have pulmonary hypertension excluded by echocardiography before attempting conception...

: The Papuan black snake (Pseudechis papuanus Serpentes: Elapidae) is endemic to Papua New Guinea, Indonesian Papua and Australia's Torres Strait Islands. We have investigated the biological activity and proteomic composition of its venom. The P. papuanus venom proteome is dominated by a variety (n≥18) of PLA2s, which together account for ~90% of the venom proteins, and a set of low relative abundance proteins, including a short-neurotoxic 3FTx (3.1%), 3-4 PIII-SVMPs (2.8%), 3 cysteine-rich secretory proteins (CRISP; 2...

A simple eco-friendly approach for the hasty synthesis of stable, potent and benign silver nanoparticles (AgNPs) using seagrass, Syringodium isoetifolium was proposed and described here. The UV-Vis, DLS, XRD, AFM, FESEM, EDX and HRTEM analysis highly characterized and confirmed the presence of polydispersed (2-50nm) spherical and stable AgNPs. FT-IR and phytochemical analysis suggested that the proteins act as reducing and also as capping agent. A hypothetical approach using bioinformatics tools revealed that the Phytochrome B protein of S...

Glycerol and trehalose have been widely examined as protective agents in the cryopreservation of red blood cells (RBCs). However, the effectiveness of these reagents alone on cell viability is moderate. Here, the addition of salidroside attenuated oxidative damage of sheep RBCs prior to and post cryostorage. The supplementation of salidroside to the cryopreservation media containing 10% glycerol improved RBC survival by approximately 61.1±4.8% vs 37.9±4.6%. A smaller effect was seen in RBCs cryopreserved in 300 mM trehalose where the addition of salidroside improved survival by 7...

Most published cases of cytomegalovirus infection in pregnancy relate to congenital abnormalities in neonates infected in early pregnancy, while the mother remains asymptomatic. We describe a diagnostically challenging case of an immunosuppressed woman with scleroderma who developed deranged liver function tests attributed to intrahepatic cholestasis of pregnancy and haemolysis, elevated liver enzymes and low platelets syndrome but was ultimately found to have disseminated cytomegalovirus. Cytomegalovirus can present in a myriad of ways...

BACKGROUND:  Pathogenesis of severe Plasmodium vivax malaria is poorly understood. Endothelial dysfunction and reduced nitric-oxide (NO) bioavailability characterise severe falciparum malaria, but have not been assessed in severe vivax malaria. METHODS:  In patients with severe (n=9) and non-severe (n=58) vivax malaria, and in healthy controls (HCs, N=79) we measured NO-dependent endothelial function using reactive hyperemia-peripheral arterial tonometry (RH-PAT), and assessed associations with arginine, asymmetric dimethylarginine (ADMA) and haemolysis...

OBJECTIVE: Diagnosis of hyperbilirubinaemia may rely on direct bilirubin (DBIL) measurement. Specimen suitability for DBIL depends on the degree of haemolysis present and method specifications. Our study reassesses the empiric, syncretised haemolysis guidance for DBIL measurement. METHODS: Diazo and vanadate-oxidation assays for DBIL are compared, using sera from adults and neonates. Subsequent data analyses and statistics guide our conclusions on the clinical utility of haemolysed sera...

BACKGROUND: Haemoglobinuria is an uncommon complication of severe malaria, reflecting acute intravascular haemolysis and potentially leading to acute kidney injury. It can occur early in the course of infection as a consequence of a high parasite burden, or may occur following commencement of anti-malarial treatment. Treatment with quinine has been described as a risk factor; however the syndrome may also occur following treatment with intravenous artesunate. In Malaysia, Plasmodium knowlesi is the most common cause of severe malaria, often associated with high parasitaemia...
