In this article we propose that there are two universal properties for phonological stop assibilations, namely (i) assibilations cannot be triggered by /i/ unless they are also triggered by /j/, and (ii) voiced stops cannot undergo assibilations unless voiceless ones do. The article presents typological evidence from assibilations in over 30 languages supporting both (i) and (ii). It is argued ...

introduction: the main purpose of donor selection is not only the donor protection from blood donation complications but also the blood recipient not be expose to blood- transmitted diseases. this study aimed to determine the reason for exemption from donors among blood donor's who refer to ilam blood transfusion organization. materials and methods: this is a retrospective and descriptive ...

Blood transfusion has a well-documented clinical significance in several medical scenarios for instance severe anemia, massive blood loss caused by trauma, and major surgeries. Nevertheless, been associated with post-transfusion complications, such as mismatch reactions, transfusion-transmitted infections (TTIs).

Invariantism proposed by [Braun, 2013] aims to maintain full identity of semantic content between all uses of ‘might’. I invoke well-known facts regarding diachronic change in meanings of modals to argue that invariantism commits us to implausible duplication of familiar processes of lexical semantic change on the level of “lexical pragmatics”, with no obvious payoff. [Braun, 2013] proposes an ...

The safety of the blood supply, an issue in the 1970s and 1980s, created an increased need to screen the blood supply for HIV-1 and hepatitis C virus infections. The possibility exists that other contamination could again affect the blood supply. This has resulted in the increased use of strategies to minimize the transfusion of allogeneic blood, such as autologous blood predeposit for elective...

OBJECTIVE Postpartum hemorrhage (PPH) is an important cause of maternal mortality (MM) around the world. Seventy percent of the PPH corresponds to uterine atony. The objective of our study was to evaluate multicenter PPH cases during a 10-month period, and evaluate severe postpartum hemorrhage management. STUDY DESIGN The study population is a cohort of vaginal delivery and cesarean section p...

BACKGROUND Red blood cell (RBC) transfusions are a common, life-saving therapy for many patients, but they have also been associated with poor clinical outcomes. We identified unusual, pleomorphic structures in human RBC transfusion units by negative-stain electron microscopy that appeared identical to those previously reported to be bacteria in healthy human blood samples. The presence of viab...

T HE ERYTHROCYTES of patients with Paroxysmal Nocturnal Hemoglobinuria (PNH) hemolyse at 37 C. in normal compatible human sera in the absence of demonstrable antibody. The reaction is complement dependent and in vivo causes a hemolytic anemia of varying severity. The diagnostic acid hemolysis test for this disorder is performed by demonstrating hemolysis of suspect erythrocytes in the patient’s...
