A prenatally detected adrenal cyst treated by adrenal-sparing surgery: case report and review of the literature
A neonatal case of left adrenal cyst detected in utero and successfully treated by adrenal-sparing surgery is presented and discussed with review of the literature. Incidentally discovered prenatal adrenal masses present a diagnostic dilemma. Benign and malignant conditions can present as a fetal suprarenal mass. There is a wide spectrum of management modalities ranging from followup by serial sonographic scanning during pregnancy to early primary excision of the mass. We report a neonate with prenatal diagnosis of a cystic mass arising from the left adrenal gland. Postnatal excision of the mass without adrenalectomy was carried out. Frozen sections of the mass and a biopsy of the left adrenal gland confirmed the benign nature of the cyst and normal adrenal tissue. The uniloculated cyst was reported as a pseudocyst. After surgery, the recovery was uneventful, and the patient was discharged 4 days postoperatively in good condition. On the basis of this case and review of the literature, we may conclude that early primary surgical excision is recommended for either diagnosis or treatment if the results of prenatal or postnatal imaging studies are unreliable for the precise diagnosis of suprarenal mass. Adrenal-sparing surgery is recommended if pathological evaluation of frozen sections has confirmed the benign nature of the mass.Keywords: adrenal-sparing surgery, neonates, prenatal diagnosis, suprarenal cys

Finite-dimensional Lie algebras of order F
Lie algebras are natural generalisations of Lie algebras (F=1) and Lie
superalgebras (F=2). When not many finite-dimensional examples are known.
In this paper we construct finite-dimensional Lie algebras by an
inductive process starting from Lie algebras and Lie superalgebras. Matrix
realisations of Lie algebras constructed in this way from

, are given. We obtain non-trivial
extensions of the Poincar\'e algebra by In\"on\"u-Wigner contraction of certain
Lie algebras with .Comment: 20 pages, Late

Robust estimation of bacterial cell count from optical density
Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-cost, and highly accessible OD calibration protocols across 244 laboratories, applied to eight strains of constitutive GFP-expressing E. coli. Based on our results, we recommend calibrating OD to estimated cell count using serial dilution of silica microspheres, which produces highly precise calibration (95.5% of residuals <1.2-fold), is easily assessed for quality control, also assesses instrument effective linear range, and can be combined with fluorescence calibration to obtain units of Molecules of Equivalent Fluorescein (MEFL) per cell, allowing direct comparison and data fusion with flow cytometry measurements: in our study, fluorescence per cell measurements showed only a 1.07-fold mean difference between plate reader and flow cytometry data
Synthesis and characterization of new Schiff bases and their cobalt(II), nickel(II), copper(II), zinc(II), cadmium(II) and mercury(II) complexes
WOS: 000230019700012Nickel(II), copper( II), cobalt( II), zinc( II), cadmium( II) and mercury( II) complexes chelates containing the Schiff base ligands methyliminoisonitroso-2-acetylnaphthalene (HL1) and benzyliminoisonitroso-2-acetylnaphthalene (HL2) have been prepared. The results suggest that the Schiff bases function as bidentate ligands and indicate a mononuclear structure for the Cu(II) complexes with square-planar geometry. The Ni(II), Zn(II), Hg(II) and Cd(II) complexes are of tetrahedral geometry and the Co(II) complexes with octahedral geometry with water molecules at the axial positions. These compounds have been characterized by elemental analyses, magnetic susceptibility, mass, IR, UV, H-1 and C-13 NMR spectroscopy
Synthesis and Characterization of Some Metal Complexes of Isonitroso-2-acetylnaphthalene Derivative
WOS: 000386572500023Nickel(II), copper(II), and zinc(II) complexes with the Schiff base obtained from isonitroso-2-acetylnaphthalene and 1,2-phenylenediamine were synthesized. The compounds were characterized by elemental analyses, FT-IR, UV-Vis, and H-1 and C-13 NMR spectra, conductance measurements, magnetic susceptibility measurements, and thermal analysis. The results suggest tetradentate coordination of the symmetrical Schiff base ligand through the two oxime oxygen atoms and two azomethine nitrogen atoms. The molar conductance data showed that the synthesized complexes are non-electrolytes.Research Foundation of the Nigde University (BAP) [P.N.

Synthesis and characterization of some vic-dioxime and its mononuclear complexes
WOS: 000247004300007In this study, acetophenone is used as a basis substance. omega-Isonitrosoacetophenone has been synthesized from nitrosyl with amyl nitrite of acetophenone in the presence of sodium ethoxide. Subsequently, anti-phenylglyoxime has been prepared by reacting omega-isonitrosoacetophenone with hydroxylamine and sodium acetate in a ethanolic media. Chlorophenylglyoxime has been obtained from reaction with chlorine gases. Then, three aminophenylglyoxime (ligands) have been prepared by the reaction of chlorophenylglyoxime and the corresponding amines. The Ni(II), Co(II), and Cu(II) complexes with BF2+-bridge of anilinophenylglyoxime and 2,4-dimethylanilinophenylglyoxime were prepared. Then polymeric metal complexes with BF2+-bridge of dopamiophenylglyoxime were prepared. Their structures were identified by FT-IR, H-1 NMR, and ICP-AES spectral data, elemental analysis and magnetic measurements
