Slurry-phase hydrocracking utilizing metal-containing oil-soluble compounds as precursors of dispersed catalysts is an effective approach for heavy oil upgrading. We propose applying metal-based p-tert-butylcalix[6]arene (TBC[6]s) organic species catalyst to enhance catalytic hydrogenation reactions involved in the upgrading vacuum gas (VGO). Co- and Ni-based TBC[6]s were synthesized characteri...

OBJECTIVES To evaluate BD MGITTM TBc® technique for identifying the Mycobacterium tuberculosis complex using isolates obtained in liquid and solid media. METHODS A descriptive study was conducted in which 117 isolates were analyzed by the immune-chromatography technique obtained from solid and liquid cultures to identify the Mycobacterium tuberculosis complex. The kappa coefficient was calcul...

Recent measurements of the lepton mixing angle θ13 by the Daya Bay and RENO reactor experiments are consistent with the relationship θ13 ≈ θC/ √ 2 where θC is the Cabibbo angle. We propose Tri-bimaximal-Cabibbo (TBC) mixing, in which sin θ13 = sin θC/ √ 2, sin θ23 = 1/ √ 2 and sin θ12 = 1/ √ 3. We show that TBC mixing may arise approximately from Tri-bimaximal, Bi-maximal or Golden Ratio neutri...

The Rab5 GTPase and phosphatidylinositol-3 phosphate (PI(3)P) coordinately regulate endosome trafficking. Rab5 recruits Vps34, the class III PI3-kinase (PI3K), to generate PI(3)P and recruit PI(3)P binding proteins. Loss of Rab5 and loss of Vps34 have opposite effects on endosome size suggesting that our understanding of how Rab5 and PI(3)P cooperate is incomplete. Here we report a novel regula...

The contamination of bulk samples of cow’s raw milk (n = 491) by psychrotrophic lipolytic bacteria (PLiBC), total count of psychrotrophic bacteria (PBC) and mesophilic bacteria (TBC) was monitored for two years on eight dairy farms and the correlations among these groups of bacteria were analysed. An increase in TBC, PBC and PLiBC and in the values of free fatty acids (FFA) was tested experimen...

Video-assisted thoracoscopic surgery (VATS) is a diagnostic method, used with increasing frequency in recent years, in the diagnosis of interstitial lung diseases. There are significant differences in the diagnosis of diseases which are diagnosed with clinical, biochemical and radiological investigation and with pathological evaluation of material obtained by VATS. In our study, five patients w...

STUDY OBJECTIVES Although the benefit of pulmonary rehabilitation (PR) has been demonstrated for patients with COPD, the benefit for patients with non-COPD lung disorders is still unclear. In the present study, we compared the effect of PR on patients with post-tuberculosis (TBC) lung disorders and patients with COPD. DESIGN We performed a prospective nonrandomized open trial over a 9-week pe...

Abscisic acid (ABA) is a classical phytohormone which plays an important role in plant stress resistance. Moreover, ABA is also found to regulate the activation of innate immune cells and glucose homeostasis in mammals. Therefore, this 'stress hormone' is of great importance to theoretical research and agricultural and medical applications. Botrytis cinerea is a well-known phytopathogenic ascom...

Dense core vesicles (DCVs) are thought to be generated at the late Golgi apparatus as immature DCVs, which subsequently undergo a maturation process through clathrin-mediated membrane remodeling events. This maturation process is required for efficient processing of neuropeptides within DCVs and for removal of factors that would otherwise interfere with DCV release. Previously, we have shown th...

Hexagon TB is intended for the rapid diagnostics of tuberculosis. Tuberculosis is a contagious and epidemic disease. According to the data published by WHO, 3-4 millions of patients are diagnosed with this disease annually. In 2004, 107 new cases were discovered in the area of Tuzla Municipality. Annual incidence of this disease is 62,9 per 100 000 inhabitants in Bosnia and Herzegovina; 28,9 in...
