Newborn Screening for Hemoglobinopathies and Red Cell Enzymopathies in Tripura State: A Malaria-Endemic State in Northeast India.

Hemoglobinopathies are a group of inherited single gene disorders. There are reports on hemoglobin (Hb) variants identified in the tribal and non-tribal populations of Tripura State in northeastern India. This study aimed to determine the spectrum of hemoglobinopathies and enzymopathies by newborn screening in Tripura State and assess the extent of neonatal jaundice. A total of 2400 cord blood samples were collected and analyzed by high performance liquid chromatography (HPLC). Further confirmation of any abnormal HPLC was done by DNA analysis. The samples were also screened for deficiency of enzymopathies, glucose-6-phosphate dehydrogenase (G6PD) deficiency and pyruvate kinase. Of 2400 cord blood samples screened, 225 (9.3%) were Hb E (HBB: c.79G>A) heterozygotes, 80 (3.3%) were Hb E homozygotes and one carried Hb E-ß-thalassemia (ß-thal). Other Hb abnormalities were also detected including 15 Hb S (HBB: c.20A>T) heterozygotes, two Hb D-Punjab (HBB: c.364G>C) heterozygotes and two compound heterozygotes for Hb D-Punjab and Hb E. Of the 80 homozygous Hb E babies, four were non-tribal and 76 babies were tribal, and 225 patients carried Hb E trait, 141 were tribal, while 84 were non-tribal. Of 40 G6PD deficient babies identified, 13 had coinherited Hb E and two babies had pyruvate kinase deficiency. α Genotyping was performed in 162 affected babies, 50 of them carried α gene deletions. Newborn screening programs for Hb E, other hemoglobinopathies and G6PD deficiency must be encouraged in the malaria-endemic northeastern region of India. Drug-induced hemolysis can also be avoided by screening for G6PD deficiency at birth.

SIRT1 and NAD+ precursors: Therapeutic targets in multiple sclerosis a review.

Neurodegeneration is an important determinant of disability in multiple sclerosis (MS) but while currently approved treatments reduce inflammation, they have not been shown to reduce neurodegeneration. SIRT1, a NAD dependent protein deacetylase, has been implicated in the pathogenesis of neurodegeneration in neurological diseases including MS. We have studied the role of SIRT1 in experimental autoimmune encephalomyelitis (EAE) and found evidence for a neuroprotective role. In this review we summarize the most recent findings from the use of SIRT1 activators and SIRT1 overexpression in transgenic mice. These data support provide a rational for the use of SIRT1 activators in MS.

An eventful journey from menarche to successful motherhood.

Herlyn-Werner-Wunderlich syndrome is an uncommon variant of mullerian duct anomaly and the approach to its diagnosis requires a high index of suspicion and vigilant work up. Presented here is a case of a 26-year-old woman who had the aforementioned anomaly and was pursued for nearly 10 years to provide her with a fruitful obstetric outcome after having undergone Strassman's metroplasty at a young age of 15 years.

1-(3-Chloro-4-fluoro-phen-yl)-5-(2-diazo-acet-yl)-4-phenyl-pyrrolidin-2-one.

In the title compound, C(18)H(13)ClFN(3)O(2), the pyrrolidine ring adopts an envelope conformation and the planar part is rotated by 4.3 (6)° from the plane of the benzene ring and is almost perperdicular both to the diazo-acetyl unit [dihedral angle = 78.93 (7)°] and the phenyl ring [dihedral angle = 86.07 (7)°]. In the crystal, mol-ecules are linked into a three-dimensional framework by C-H⋯O inter-actions. The mol-ecular conformation is stabilized by an intra-molecular C-H⋯O hydrogen bond.

Diethyl 1-(4-methyl-phen-yl)-3-phenyl-5-oxopyrrolidine-2,2-dicarboxyl-ate.

In the title compound, C(23)H(25)NO(5), the lactam ring adopts an envelope conformation and both eth-oxy-carbonyl side chains show an s-cis conformation: one is nearly planar, the dihedral angle between CO(2) and OCH(2)CH(3) groups being 7.95 (14)° and the other is almost orthogonal, the C-O-C-C torsion angle being 85.33 (9)°. Dimers related by inversion symmetry are stabilized by C-H⋯O hydrogen bonds. The crystal structure is consolidated by weak intermolecular C-H⋯O inter-actions. Weak intra-molecular inter-actions of the same kind also occur.

Neurological disorders in children and adolescents.

OBJECTIVE: To ascertain the prevalence of active epilepsy, febrile seizures (FS), cerebral palsy (CP) and tic disorders (TD) in aged 19 years or less. METHODS: This was a cross-sectional observational study conducted as a two-stage door-to-door survey of a stratified randomly selected population in 2003-04. Trained field workers screened the population followed by case examination by the field neurologist. RESULTS: A total of 16979 (male 8898, female 8081) subjects aged

Novel and rapid palladium-assisted 6pi electrocyclic reaction affording 9,10-dihydrophenanthrene and its analogues.

Design and synthesis of a neutral fluorescent macrocyclic receptor for the recognition of urea in chloroform.

[structure: see text] An artificial macrocyclic fluorescent receptor 1 has been designed and synthesized for the recognition of urea. 1 shows significant fluorescence quenching on complexation with urea and thiourea in chloroform and thus may be used as a synthetic fluorescent molecular sensor for their determination in a nondegradative way.

Diethyl 1-(4-fluorophenyl)-3-(2-furyl)-5-oxopyrrolidine-2,2-dicarboxylate and diethyl 1-(3,4-dichlorophenyl)-3-(2-furyl)-5-oxopyrrolidine-2,2-dicarboxylate.

The title compounds, C20H20FNO6 and C20H19Cl2NO6, respectively, may exhibit bioactivity. In these compounds, the pyrrolidine ring adopts a conformation intermediate between envelope and half-chair. Only one of the two ethoxycarbonyl side chains is nearly planar. Centrosymmetric pairs are formed, and the crystal structure is stabilized by weak C-H.O hydrogen bonds and van der Waals interactions.
