Comparative efficacy of machine-learning models in prediction of reducing uncertainties in biosurfactant production.

An accurate and reliable forecast of biosurfactant production with minimum error is useful in any bioprocess engineering. Bacterial isolate FKOD36 capable of producing biosurfactant was isolated in this study and pre-inoculums was prepared from the agar slants in a small test tube and incubated at 30 °C for 24 h at 120 rpm. Due to inherent non-linearity characteristics of the data set in a bioprocess, conventional modeling techniques are not adequate for predicting biosurfactant production in a microbiological process.

Hydrolysis of the amide bond in histidine- and methionine-containing dipeptides promoted by pyrazine and pyridazine palladium(II)-aqua dimers: Comparative study with platinum(II) analogues.

Two dinuclear palladium(II) complexes, [{Pd(en)Cl}(μ-pz)](NO) and [{Pd(en)Cl}(μ-pydz)](NO), have been synthesized and characterized by elemental microanalysis and spectroscopic (H and C NMR, IR and UV-vis) techniques (en is ethylenediamine; pz is pyrazine and pydz is pyridazine). The square planar geometry of palladium(II) metal centers in these complexes has been predicted by DFT calculations. The chlorido complexes were converted into the corresponding aqua complexes, [{Pd(en)(HO)}(μ-pz)] and [{Pd(en)(HO)}(μ-pydz)], and their reactions with N-acetylated l-histidylglycine (Ac-l-His-Gly) and l-methionylglycine (Ac-l-Met-Gly) were studied by H NMR spectroscopy.

Living unrelated donor kidney transplantation--a fourteen-year experience.

Background: In countries without a national organization for retrieval and distribution of organs of the deceased donors, problem of organ shortage is still not resolved. In order to increase the number of kidney transplantations we started with the program of living unrelated - spousal donors. The aim of this study was to compare treatment outcome and renal graft function in patients receiving the graft from spousal and those receiving ghe graft from living related donors.

Genetic diversity of HIV type 1 in Montenegro.

Human immunodeficiency virus type 1 (HIV-1) is characterized by high genetic variability due to its high replication rate and the lack of proofreading activity of the reverse transcriptase enzyme. On the basis of phylogenetic analysis performed on numerous isolates from all over the world, HIV-1 is subdivided into types, subtypes, subsubtypes, circulating recombinant forms, and unique recombinant forms. No data are currently available about the circulation of HIV-1 types in Montenegro.

[Comparison of clinical and laboratory characteristics of viral hepatitis A and E in Montenegro].

Introduction: Hepatitis E has many similarities in with hepatitis A concerning clinical picture, route of transmission and nonexistence of chronicity. Comparison of clinical and laboratory parameters of patients with hepatitis A and E to estimate characteristics of these diseases.

Material And Methods: Total of 54 patients divided into two groups was investigated: 27 had hepatitis A, others had hepatitis E.
