Molecular characterization of glucose-6-phosphate dehydrogenase gene defect in the Kuwaiti population.

CONTEXT: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is one of the most common human enzyme deficiencies. More than 130 different molecular abnormalities have been described worldwide, with considerable variation in the enzyme among various racial groups. Data from Kuwaiti populations are scarce, and the studies available are the result of screening male blood donors who may not be truly representative of the Kuwaiti population. OBJECTIVE: The objective of this study was to investigate the mutation spectrum of the G6PD gene among Kuwaiti Arabs. DESIGN: DNA was extracted from 82 G6PD-

[Intervention strategies in refractory heart failure].

Although the additional therapies with beta-blockers and spironolactone have recently proved to be significantly beneficial for the treatment of advanced heart failure, in the end stages of this disease the prognosis remains quite poor. Moreover, the quality of life of patients with advanced heart failure is still heavily influenced by symptoms and by a high rate of hospitalizations. In selected patients heart transplantation constitutes the only chance, but the low availability of donors limits a wider diffusion of this procedure. Mechanical left ventricular assistance is still considered a b

Selective delivery of nitric oxide to a cellular target: a pseudosubstrate-coupled dinitrosyl-iron complex inhibits the enteroviral protease 2A.

Nitric oxide (NO) regulates multiple biological processes. To use NO as a potential therapeutic substance, a more selective modulation of individual NO targets is desirable. Here, we tested whether peptide conjugation of the dinitrosyl-iron complex (DNIC), a potent NO donor, confers targeted NO delivery. As target, we used the protease 2A of Coxsackie-B-viruses (2A(pro)), which can cause dilated cardiomyopathy. Through S-nitrosylation, NO inhibits this protease, which is essential for viral replication. The tetrapeptide Leu-Ser-Thr-Cys (LSTC) (based on the 2A(pro) substrate recognition motif)

Evaluation of 12 commercial tests for detection of Epstein-Barr virus-specific and heterophile antibodies.

Ten microbiological departments in Norway have participated in a multicenter evaluation of the following commercial tests for detection of Epstein-Barr virus (EBV)-specific and heterophile antibodies: CAPTIA Select viral capsid antigen (VCA)-M/G/EBNA (Centocor Inc.), Enzygnost anti-EBV/immunoglobulin M (IgM) and IgG (Dade Behring), Vironostika EBV VCA IgM/IgG/EBNA enzyme-linked immunosorbent assay (ELISA) (Organon Teknika), SEROFLUOR immunofluorescence assay and EBV Combi-Test (Institute Virion Ltd.), anti-EBV recombinant IgM- and IgG-early antigen/EBNA IgG ELISA (Biotest Diagnostics), EBV IgM

The cGMP-specific phosphodiesterase inhibitor E4021 dilates the pulmonary circulation.

We investigated the pulmonary vascular effects of E4021, a potent inhibitor of cGMP-specific phosphodiesterase, in control late-gestation fetal lambs, and in newborn lambs with persistent pulmonary hypertension (PPHN) after prenatal ligation of the ductus arteriosus. E4021 alone significantly relaxed fifth-generation pulmonary arteries isolated from control fetal lambs, an effect completely blocked after inhibition of nitric oxide synthase (NOS). In contrast, E4021 did not relax pulmonary arteries isolated from hypertensive lambs. Pretreatment with E4021 (10(-7) M) significantly enhanced relax

Human antibody responses to HIV type 1 glycoprotein 41 cloned in phage display libraries suggest three major epitopes are recognized and give evidence for conserved antibody motifs in antigen binding.

A large panel of human Fab fragments against the gp41 subunit of the HIV-1 envelope glycoprotein was isolated by panning six phage-displayed antibody libraries against recombinant gp41. The libraries were prepared from HIV-1-seropositive donors. Twenty-three Fabs recognizing conformation-dependent determinants on gp41 were isolated. Further selection of libraries against (1) gp41 ligated with Fabs from the initial selection and against (2) a recombinant gp41-containing gp140 protein yielded five additional Fabs. Competition of members of the Fab panel with one another and with previously descr

Interferon and beta 2-microglobulin in patients with common variable immunodeficiency or selective IgA deficiency.

The production of interferon (IFN) after stimulation of peripheral blood mononuclear cells with Sendai virus or phytohemagglutinin was studied in patients with common variable immunodeficiency (CVID) or selective IgA deficiency. Cells from CVID patients produced significantly more Sendai virus-induced (alpha) and mitogen-induced (gamma) IFN than cells from healthy control subjects. By contrast, some patients with selective IgA deficiency produced subnormal amounts of IFN-alpha. Neither IFN-alpha nor IFN-gamma was detectable in sera from the two categories of patients using radioimmunoassays wi

Assisted reproductive technology surveillance - United States, 2004.

PROBLEM/CONDITION: In 1996, CDC initiated data collection regarding assisted reproductive technology (ART) procedures performed in the United States, as mandated by the Fertility Clinic Success Rate and Certification Act of 1992 (FCSRCA) (Public Law 102-493 [October 24, 1992]). ART includes fertility treatments in which both eggs and sperm are handled in the laboratory (i.e., in vitro fertilization and related procedures). Patients who undergo ART procedures are more likely to deliver multiple-birth infants than women who conceive naturally. Multiple births are associated with increased risk f

Transferable IncHI2-Associated blaLAP-2 and blaCTX-M-55 Resistance Platforms in Foodborne Salmonella.

Extended-spectrum β-lactamase genes in foodborne Salmonella enterica can disseminate through mobile multidrug-resistance platforms. IncHI2 plasmids are important resistance vehicles capable of carrying complex resistance regions and facilitating their horizontal transfer across diverse bacterial backgrounds, but the transfer and genomic organization of IncHI2 elements co-carrying blaLAP-2 and blaCTX-M-55 remain insufficiently characterized. This study investigated two multidrug-resistant foodborne isolates recovered in Shanghai in 2022: Salmonella Agona ST13 isolate Sal22C150 and Salmonella Ha

This qualitative implementation research, guided by the Consolidated Framewo

BM-164 (an H₂S-donor) modulates microRNA expression associated with reperfusion-induced ventricular fibrillation in rat hearts.

Ventricular arrhythmias are a leading cause of sudden cardiac death in myocardial infarction and heart failure. Reperfusion following ischemia can trigger severe arrhythmias, including ventricular fibrillation (VF), and microRNAs (miRNAs) which are increasingly recognized as critical regulators of these processes. This study aimed to identify miRNAs associated with ischemia/reperfusion (I/R)-induced ventricular fibrillation by comparing expression profiles between fibrillated (VF) and non-fibrillated (No VF) rat hearts. Nanostring-based screening (n = 12; 4 in each group: No I/R control, I/R n

Study of the influence of introgression from chromosome 2 of the At subgenome of cotton Gossypium barbadense L. during backcrossing with the original lines of G. hirsutum L.

The creation of chromosome substitution lines containing one pair of chromosomes from a related species is one method for introgression of alien genetic material. The frequency of substitutions in different chromosomes of the genome varies due to the selective transmission of alien chromosomes through the gametes of hybrids. The use of monosomic lines with identified univalent chromosomes and molecular genetic SSR markers at the seedling stage allowed rapid screening of the identity of the alien chromosome in backcross hybrids, significantly accelerating and facilitating the backcrossing proce

Application of Orbital Septal Fat Repositioning Combined With SVF-Gel Fillers in Lower Blepharoplasty.

BACKGROUND: Lower blepharoplasty is a widely used cosmetic surgical procedure to improve under-eye bags and tear trough deformities, aiming to enhance facial aesthetics and achieve a more youthful appearance. The formation of these deformities is often associated with factors such as aging, skin laxity, and fat displacement. Traditional surgical methods include orbital septal fat repositioning and fat grafting, each with its own advantages and limitations. Transconjunctival blepharoplasty avoids external incisions by performing the surgery through the conjunctiva, thereby reducing postoperativ
