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.

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.

Acute hepatitis E in Montenegro: epidemiology, clinical and laboratory features.

Objective: To evaluate the incidence, demographic, clinical and laboratory characteristics of patients with acute viral hepatitis E in Montenegro.

Material And Methods: A total of 400 patients with acute viral hepatitis from January 1st, 2000 to December 31st, 2007 were enrolled in the study. Serological tests for hepatitis A, B, C, D, and E viruses, Epstein-Barr virus, cytomegalovirus, and herpes simplex viruses were performed.

Poly[[tetra-aquabis-(μ-hydroxy-acetato-κO,O:O,O)-μ(2)-sulfato-κO:O'-dicadmium(II)] monohydrate].

The title compound, {[Cd(2)(C(2)H(3)O(3))(2)(SO(4))(H(2)O)(4)]·H(2)O}(n), was obtained unintentionally in a transmetallation reaction. The crystal structure contains a two-dimensional metal-organic framework based on Cd(II)-(μ-hydroxy-acetato-κ(4)O(1),O(2):O(1),O(1'))-Cd(II) zigzag chains joined together by bridging SO(4) anions. The resulting layers are shifted with respect to each other and are stacked along the c axis.

Liver enlargement associated with opportunistic infections in patients with human immunodeficiency virus infection.

Background And Aim: Liver disease is commonly present in human immunodeficiency virus (HIV) infection. The aim was to determine the frequency of liver enlargement and its association with opportunistic infections in patients with HIV infection.

Patients And Methods: A total of 400 HIV-infected patients were investigated.
