Allatostatins (ASTs) are insect neuropeptides that inhibit juvenile hormone biosynthesis by the corpora allata. We have isolated a cDNA from the cockroach Diploptera punctata that encodes a 41.5-kDa precursor polypeptide containing the AST family of peptides. Translation of the cDNA revealed a 370-amino acid pre-pro-peptide consisting of 13 AST-type peptides and appropriate processing sites for...

In the title compound, C(6)H(9)N(3)O(3), the 3-diazo-2-oxopropan-amide section of the mol-ecule is nearly planar, with a maximum deviation of 0.025 (1) Å from the mean plane of its constituent atoms. The diazo C=N=N angle is 178.0 (3)°. In the crystal, pairs of inter-molecular O-H⋯O and N-H⋯O hydrogen bonds link the mol-ecules into infinite double chains along the [100] direction. The double ch...

the theory of c-frames and c-bessel mappings are the generalizationsof the theory of frames and bessel sequences. in this paper, weobtain several equivalent conditions for dual of c-bessel mappings.we show that for a c-bessel mapping $f$, a retrievalformula with respect to a c-bessel mapping $g$ is satisfied if andonly if $g$ is sum of the canonical dual of $f$ with a c-besselmapping which  wea...

OBJECTIVE To evaluate liver regeneration modulated by ischemic preconditioning after ischemia, reperfusion and partial hepatectomy. METHODS We used 24 Wistar rats of 12 weeks of age, which were randomly assigned into four groups: control (SHAM), hepatectomy (HEP), ischemia and reperfusion (IRG) and Ischemic Preconditioning (SRG). Analyses were made on liver enzymes ALT and AST, assessment of ...

Liver necrosis was produced in rats by administering 3 doses o a mixture o carbon tetrachloide+olive oil, 2 ml/kg, ip. The liver damage was evidenced by the elevated levels serun aspartate aminotrans ferase (AST), alanine aminotransferase (AIT) and gamma glutamyl transpeptidase (gamma-GT) and by histopathological observations of liver sections. Nitrendipine, nimodipine and nisoldipine (1 mg/100...

Background: Antibiotics are increasingly being prescribed during pregnancy. Even though safe non-teratogenic drugs prescribed, due to altered pharmacokinetics pregnancy can have adverse effects on hepatic metabolism. Methods: This was a prospective analytical study conducted in the department of obstetrics and gynecology at ESIC Medical College PGIMSR, Bengaluru, Bengaluru from August 2022 Janu...
