OBJECTIVE The Helping Babies Breathe" (HBB) program is an evidence-based curriculum in basic neonatal care and resuscitation, utilizing simulation-based training to educate large numbers of birth attendants in low-resource countries. We analyzed its cost-effectiveness at a faith-based Haydom Lutheran Hospital (HLH) in rural Tanzania. METHODS Data about early neonatal mortality and fresh still...
We have developed a new method for non-invasive prenatal testing (NIPT) of paternally inherited fetal mutants for β-thalassemia (β-thal). Specially designed primer-introduced restriction analysis-polymerase chain reaction (PIRA-PCR) were used to detect four major mutations [IVS-II-654, HBB: c.316-197C > T; codon 17 (A > T), HBB: c.52A > T; -28 (A > G), HBB: c.-78A > G and codons 41/42 (-TTCT), ...
Stimulation of sheep erythropoietic progenitor cells by erythropoietin (epo) has been studied with regard to its effect on the pattern of hemoglobin production. An analysis of hemoglobin (Hb) synthesis in BFU-E- and CFU-E-derived colonies from fetuses either homozygous for HbA (AA) (homozygous also for the beta c gene responsible for HbC production) or HbB (BB) (lacking the beta c gene) indicat...
PURPOSE Heterozygous optic atrophy type1 (OPA1) mutations are responsible for dominant optic atrophy, and the down regulation of OPA1 expression in patients with Leber hereditary optic neuropathy may imply that Opa1 protein levels in mitochondria play a role in other spontaneous optic neuropathies as well. Mitochondrial and metabolic abnormalities may put the optic nerve at risk in primary open...
BACKGROUND The first minutes after birth are critical to reducing neonatal mortality. Helping Babies Breathe (HBB) is a simulation-based neonatal resuscitation program for low resource settings. We studied the impact of initial HBB training followed by refresher training on the knowledge and skills of the birth attendants in facilities. METHODS We conducted HBB trainings in 71 facilities in t...
background: xmn-1 polymorphism of y g globin gene ( hbg2 ) is a prominent quantitative trait loci (qtl) in β-thalassemia intermediate (β-ti). in current study, we evaluated frequency of xmn-1 polymorphism and its association with β-globin gene ( hbb ) alleles and hb f level in β-ti patients in sistan and balouchestan province, south-east of iran. methods: 45 β-ti patients were enrolled. hbb gen...
HIS report describes the chromosomal location of the hemoglobin beta-chain Tstructural locus (Hbb) in mice transmitting the flecked ( f d ) translocation (CATTANACH 1961 ), and the electrophoretic behavior of hemoglobins analyzed by acrylamide gel and cellulose acetate systems. In adult mice, the electrophoretic difference in hemoglobin determined by the locus behaves as a unit character ( GLUE...
BACKGROUND Helping Babies Breathe (HBB) has become the gold standard globally for training birth-attendants in neonatal resuscitation in low-resource settings in efforts to reduce early newborn asphyxia and mortality. The purpose of this study was to do a first-ever activity-based cost-analysis of at-scale HBB program implementation and initial follow-up in a large region of Tanzania and evalua...
Stream cipher Hiji-Bij-Bij (HBB) was proposed by Sarkar at Indocrypt’03. This cipher uses cellular automata (CA). The algorithm has two modes: a basic mode (B) and a self-synchronizing mode (SS). This article presents the first attack on B mode of HBB using 128 bit secret key. This is a known-pliantext guess-then-determine attack. The main step in the attack guesses 512 bits of unknown out of t...
