BACKGROUND: The African buffalo (Syncerus caffer) is an important role player in the savannah ecosystem. It has become a species of relevance because of its role as a wildlife maintenance host for an array of infectious and zoonotic diseases some of which include corridor disease, foot-and-mouth disease and bovine tuberculosis. To date, no complete genome sequence for S. caffer had been available for study and the genomes of other species such as the domestic cow (Bos taurus) had been used as a proxy for any genetics analysis conducted on this species...

Glanzmann thrombasthenia is a rare autosomal recessive haemorrhagic disorder. The risks of miscarriage, antepartum and postpartum haemorrhage, and neonatal complications are all increased in individuals presenting with the disease in pregnancy. Some individuals may develop antibodies to platelet glycoproteins; the presence of these antibodies is a rare cause of neonatal alloimmune thrombocytopenia and potential intracranial haemorrhage. Multidisciplinary care is paramount for ensuring optimal fetal and maternal outcomes in such cases...

In this study, we have investigated the antileishmanial activity of ten 7-chloro-4-quinolinylhydrazone derivatives. Among the compounds tested, compounds 2a and 2j presented activity against promastigotes (IC50 values of 52.5 and 21.1 μM, respectively) and compounds 2a and 2c were active against intracellular amastigotes (IC50 of 8.1 and 15.6 μM, respectively) of Leishmania amazonensis. The majority of compounds did not show toxicity against murine macrophages. Compound 2a exhibited low cytotoxicity to human erythrocytes and induced an oxidative imbalance in promastigote forms, reflected by an increase in the formation of reactive oxygen species (ROS) and a reduction of mitochondrial membrane potential...

Perioperative hemostatic management is a challenge in patients with Glanzmann thrombasthenia (GT). The standard means of preventing surgical bleeding in GT patients is platelet transfusion. However, GT patients often possess alloantibodies against GPIIb/IIIa and/or HLA, which cause resistance to platelet transfusion. HLA-matched platelet transfusion, plasmapheresis, or recombinant human-activated factor VII (rFVIIa) are alternative interventions in such cases. Monitoring of hemostasis is also critical in the management of GT patients who undergo surgery...

INTRODUCTION: Reducing bleeding episodes is very important in haematology disorders like von Willebrand disease (VWD) and Glanzmann thrombasthenia (GT). Replacement factors are very expensive although prophylactic drugs are affordable. OBJECTIVE: To study the prophylactic effects of tranexamic acid (TXA) for reduction of bleeding episodes in patients with VWD and GT in non-invasive conditions. METHODS: A controlled, double-blind before and after single-centre trial was performed in Amir-Kabir Hospital (Arak, Iran)...

We recently reported mutation analysis of the largest cohort of Glanzmann thrombasthenia (GT) patients so far examined. Sanger sequencing of coding regions, splice sites, upstream and downstream regions of the ITGA2B and ITGB3 genes identified 78 causal genetic variants (55 novel); 4 large deletions or duplications were also detected. We have now analysed the expression of non-causal gene polymorphisms in the sequenced regions of both genes in selected members of this cohort. We identified 10 mostly silent variants in ITGA2B and 37 in ITGB3; all were present in control donor databases...

The genes encoding the coagulation factors were characterized over two decades ago. Since then, significant progress has been made in the genetic diagnosis of the two commonest severe inherited bleeding disorders, haemophilia A and B. Experience with the genetic of inherited rare bleeding disorders and platelet disorders is less well advanced. Rare bleeding disorders are usually inherited as autosomal recessive disorders, while it is now clear that a number of the more common platelet function disorders are inherited as autosomal dominant traits...

BACKGROUND: Whole exome sequencing (WES) has provided a means for researchers to gain access to a highly enriched subset of the human genome in which to search for variants that are likely to be pathogenic and possibly provide important insights into disease mechanisms. In developing countries, bioinformatics capacity and expertise is severely limited and wet bench scientists are required to take on the challenging task of understanding and implementing the barrage of bioinformatics tools that are available to them...

Glanzmann thrombastenia (GT) is a rare disease of an autosomal recessive inheritance characterized with fatal bleeding tendency. The anaesthesiologist should be cognizant of the risk involved and be prepared with necessary measures. In this paper, we present a GT case of a 9-year-old male with hypospadias, which was successfully repaired after platelet transfusions according to the thromboelastography tracings.

Glanzmann's thrombasthenia is a rare platelet function disorder with an autosomal recessive pattern of inheritance. Achieving haemostasis in such patients who undergo surgical procedures always poses a significant challenge. Herein we report six cases of Glanzmann's thrombasthenia, who underwent nine surgeries under the cover of platelet-rich concentrates with or without recombinant activated factor VII . Of these, five were major surgeries such as thyroidectomy, laparotomy, Hartmann's procedure, reversal of Hartmann's procedure and a complete dental extraction...

BACKGROUND: Optimal treatment of a failed reverse shoulder arthroplasty (RSA) is unclear. In the case of poor glenoid bone stock, retaining a RSA may be infeasible. We report our experience with conversions to hemiarthroplasty. METHODS: Within 7 years, 16 patients underwent conversion to hemiarthroplasty after failed RSA. All patients had insufficient bone stock for reimplantation of another RSA. Standard radiographs and Constant, Shoulder Pain and Disability Index, and the 11-item version of the Disabilities of the Arm, Shoulder and Hand scores were assessed preoperatively and up to a minimum of 24 months after surgery...

In addition to mutations in ITG2B or ITGB3 genes that cause defective αIIbβ3 expression and/or function in Glanzmann's thrombasthenia patients, platelet dysfunction can be a result of genetic variability in proteins that mediate inside-out activation of αIIbβ3 The RASGRP2 gene is strongly expressed in platelets and neutrophils, where its encoded protein CalDAG-GEFI facilitates the activation of Rap1 and subsequent activation of integrins. We used next-generation sequencing (NGS) and whole-exome sequencing (WES) to identify 2 novel function-disrupting mutations in RASGRP2 that account for bleeding diathesis and platelet dysfunction in 2 unrelated families...

Cerebral amyloid angiopathy (CAA) is a vascular dysfunction disorder characterized by deposits of amyloid-β (Aβ) in the walls of cerebral vessels. CAA and Aβ deposition in the brain parenchyma contribute to dementia and Alzheimer's disease (AD). We investigated the contribution of platelets, which accumulate at vascular Aβ deposits, to CAA. We found that synthetic monomeric Aβ40 bound through its RHDS (Arg-His-Asp-Ser) sequence to integrin αIIbβ3, which is the receptor for the extracellular matrix protein fibrinogen, and stimulated the secretion of adenosine diphosphate (ADP) and the chaperone protein clusterin from platelets...
