abomasal ulcer is a digestive disorder in domestic ruminants. there are several forms of ulcers which produce different clinical signs. for determination of lesion prevalence, abomasa of 200 buffaloes were examined grossly and in some cases, histopathologically. one hundred and twenty seven examined abomasa (63.5%) had ulcerative lesions. all ulcers (except in 2 cases) were classified as type 1...

Background and objectives: Plumeria rubra L. (Apocynaceae) is a deciduous shrub or small tree cultivated in subtropical and tropical countries.  Its bark is prescribed to treat amoebic dysentery,   dropsy, jaundice, scabies, gonorrhea, venereal affections and wounds. In the present research, we aimed to isolate and identify the chemical constituents of the bark of ...

The solid–solid reactions of electron-donor compounds, such as: barbituric acid (1a), thiobarbituric acid (1b), 1,3-dimethyl barbituric acid (1c), phenol (1d) and resorcinol (1e) with diazotized o-nitroaniline (3), m-nitroaniline (4) and p-nitroaniline (5) catalyzed by p-toluenesulfonic acid (2) afford azo dyes by grinding in good yields. This new method totally avoids the use of inorganic acid...

Rapid synthesis of 4-ethyloctanoic acid by means of microwave irradiation is described. Diethyl malonate reacted with 2-ethyl-1-bromohexane in the presence of sodium ethoxide to give diethyl (2-ethylhexyl)malonate (1b). 1b was saponified in the solution of ethanol and potassium hydroxide and then acidified to form (2-ethylhexyl)propanedioic acid (1c), and 1c was heated and decarboxylized to giv...

In the Supplementary Information file originally published with this Article, Supplementary Figures 1c and 1d were incorrectly labelled as Figure 1a and 1b. In addition, Supplementary Figures 2b, 2c and 2d were incorrectly labelled as Figure 1c, 1d and 1e. Lastly, Supplementary Figures 1a, 1b and 2a were omitted. These errors have been corrected in the Supplementary Information that now accompa...

The general synthesis of [Ni(Cp)(X)(NHC)] complexes from a nickel halide, CpLi, and a carbene solution is reported. This procedure yields unprecedented complexes with ring-expanded NHC ligands (RE-NHC) of six- (1a, 1b), seven- (1c), and eight-membered (1d) heterocycles. The NMR spectra of 1a-1d are consistent with the hindered rotation of Ni-Ccarbene and N-CMes bonds, while X-ray analyses of 1b...

A series of computational studies have been undertaken to investigate the electronic structures and bonding schemes for six hetero-substituted borane cages, all of which have been presented in the literature as potential hypho structures. The six species are hypho-7,8-[C2B6H13](-) (1a), hypho-7,8-[CSB6H11](-) (1b), hypho-7,8-[S2B6H9](-) (1c), hypho-7,8-[NSB6H11] (1d), exo-7-Me-hypho-7,8-[NCB6H1...

In the embryos of the gastropod Ilyanassa obsoleta, the development of several ectodermal structures requires an inductive interaction between the micromeres and the D macromere. The first quartet micromeres (1a, 1b, 1c and 1d) contribute to the head of the larva and descendants of 1a and 1c normally develop the eyes. The eyes do not develop if 1a and 1c are removed at the eight-cell stage. How...

a. That therapeutic iron be used to correct diagnosed iron deficiency (1D). b. Parenteral iron (intravenous) is administered in preference to oral iron to correct iron deficiency. As it is more likely to: • achieve target haemoglobin (Hb) levels (1B), • maintain ferritin and transferrin saturation (%TSAT) at target ranges (1C), • reduce erythropoiesis stimulating agent (ESA) dose requirements (...
