Nefopam hydrochloride (NFH) is a non-opioid centrally acting analgesic drug used to treat chronic condition such as neuropathic pain. In current research, sustained release nefopam hydrochloride loaded nanospheres (NFH-NS) were auspiciously synthesized using binary mixture of eudragit RL 100 and RS 100 with sorbitan monooleate as surfactant by quasi solvent diffusion technique and optimized by 3(5) Box-Behnken designs to evaluate the effects of process and formulation variables. Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetric (DSC) and X-ray diffraction (XRD) affirmed absence of drug-polymer incompatibility and confirmed formation of nanospheres...

Many different blood group systems, such as Rh, ABO, Kell, Kidd, Duffy, MNS, have been reported as causes of hemolytic disease of the newborn. Hemolysis due to minor blood group incompatibility in the fetus or newborn has been determined in isolated case reports. Here, we report a case of a patient who had received red cell transfusion due to severe Rh c and E incompatibility, leading to hemolytic anemia with heart failure. The mother and the baby were grouped B and B, respectively, both being positive for RhD antigen...

ABO incompatibility is not a contraindication for allogeneic bone marrow transplantation, but this procedure requires an extra effort for erythrocyte or plasma depletion in certain well established conditions. Some acute or delayed immunohematological complications such as acute or chronic hemolysis and pure red cell aplasia may be encountered. In this study the outcome and transplant related complications of ABO incompatible and identical cases, who have received allogeneic peripheral blood stem cells from their HLA identical siblings were compared with each other...

BACKGROUND: Jaundice is the commonest neonatal ailment requiring treatment. Untreated, it can lead to acute bilirubin encephalopathy (ABE), chronic bilirubin encephalopathy (CBE) or death. ABE and CBE have been largely eliminated in industrialised countries, but remain a problem of largely undocumented scale in low resource settings. As part of a quality-improvement intervention in the Neonatal Care Units of two paediatric referral hospitals in Myanmar, hospitals collected de-identified data on each neonate treated on new phototherapy machines over 13-20 months...

BACKGROUND: The enzyme, Glucose-6-phosphate dehydrogenase (G6PD), deficiency leads to impaired production of reduced glutathione and predisposes the red cells to be damaged by oxidative metabolites, causing hemolysis. Deficient neonates may manifest clinically as hyperbilirubinemia or even kernicterus. OBJECTIVE: This study was carried out to detect erythrocyte G6PD deficiency in neonatal hyperbilirubinemia. METHODS AND DESIGN: To determine the frequency and effect of G6PD deficiency, this study was conducted on 202 neonates with indirect hyperbilirubinemia...

The authors present the case of a newborn of an Rh-factorsensitized mother, who received early hospital discharge while icteric only to be readmitted at an Emergency Service at five days of age with signs of kernicterus. Despite treatment given, the neonate progressed with a clinical picture of bilirubin encephalopathy. The lack of interaction between the obstetric and neonatal teams, premature hospital discharge, and lack of concern of neonatologists with jaundice in a full-term infant are highlighted as causes of a condition that should have disappeared if there had been adequate prevention...

Single-molecule Förster resonance energy transfer (smFRET) is an important tool for studying disordered proteins. It is commonly utilized to infer structural properties of conformational ensembles by matching experimental average energy transfer ⟨E⟩exp with simulated ⟨E⟩sim computed from the distribution of end-to-end distances in polymer models. Toward delineating the physical basis of such interpretative approaches, we conduct extensive sampling of coarse-grained protein chains with excluded volume to determine the distribution of end-to-end distances conditioned upon given values of radius of gyration Rg and asphericity A...

BACKGROUND: Regular plasma donors who produce high titre anti-D immunoglobulin (Ig) are overseen by the Australian Red Cross Blood Service RhD Program. New donors to the program are immunised with small amounts of RhD-positive RBCs, whilst donors who have developed anti-D due to previous RhD-incompatible blood transfusion or pregnancy are boosted with RhD-positive RBCs to maintain a high level of serum anti-D Ig. A significant proportion of primarily immunised individuals do not respond to RhD immunisation and are therefore unnecessarily exposed to the risks involved in RBC sensitisation...

In Nature, incompatible catalytic transformations are being carried out simultaneously through compartmentalization that allows for the combination of incompatible catalysts in tandem reactions. Herein, we take the compartmentalization concept to the synthetic realm and present an approach that allows two incompatible transition metal catalyzed transformations to proceed in one pot in tandem. The key is the site isolation of both catalysts through compartmentalization using a core-shell micellar support in an aqueous environment...

Platelet transfusions have contributed to the revolutionary modern treatment of hypoproliferative thrombocytopenia. Despite the long-term application of platelet transfusion in therapeutics, all aspects of their optimal use (i.e., in cases of ABO and/or Rh (D incompatibility) have not been definitively determined yet. We reviewed the available data on transfusion practices and outcome in ABO and RhD incompatibility and platelet refractoriness due to anti-human leukocyte antigen (HLA) antibodies. Transfusion of platelets with major ABO-incompatibility is related to reduced posttransfusion platelet (PLT) count increments, compared to ABO-identical and minor, but still are equally effective in preventing clinical bleeding...

Hyperhemolysis is a severe and potentially life-threatening complication of transfusion described in numerous case reports and gaining recognition since 2009 via the UK Serious Hazards of Transfusion scheme. Although it is predominantly seen in patients with sickle cell disease, there are several reports of this complication in patients with other hemoglobinopathies as well as patients with a range of other hematologic diagnoses who have blood transfusions as part of their management. Our understanding of the underlying pathophysiology of this subtype of delayed transfusion reaction has increased over the last few years; however, there are still questions, which remain unanswered...

OBJECTIVE: Anti-D immunoglobulin is applied to all pregnant women having RhD incompatibility to prevent hemolytic disease of the newborn. The aim of this study is to determine fetal RhD status in the Rh incompatible pregnancies with an non-invasive technique; free fetal DNA isolation from maternal circulation. In the case of Rh incompatibility especially with a history of previous fetal anemia, it can be beneficial to know Rh status antenatally in terms of monitoring fetuses with Rh positive [RhD(+)] status consciously...
