Abatement of pharmaceutical pollutants from aquatic systems is crucial but remains a challenge. Semiconductor photocatalysis has emerged as an eco-friendly technique that utilizes renewable solar energy to address environmental issues. Naturally occurring and earth abundant hematite (Fe2O3) ores can be incorporated suitable component photocatalyst. Herein, Brazilian was partially phase transfor...

Ziehl-Neelsen (Z-N) staining of cerebrospinal fluid (CSF) for acid-fast bacilli (AFB) is the cornerstone of the laboratory diagnosis of tuberculous meningitis (TBM). However, the sensitivity of conventional Z-N staining for the detection of AFB in CSF specimens is suboptimal. The present study aimed to compare the practicality of modified Z-N staining with light microscopy and fluorescence micr...

Seasonal dynamics of net photosynthesis (Anet) in 2-year-old seedlings of Pinus brutia Ten., Pinus pinea L. and Pinus pinaster Ait. were investigated. Seedlings were grown in the field in two light regimes: sun (ambient light) and shade (25% of photosynthetically active radiation (PAR)). Repeated measures analyses over a 12-month period showed that Anet varied significantly among species and fr...

the interaction between propranolol (prop) and human serum albumin (hsa) was studied in the presence of dimethyl methylphosphonate (dmmp). dmmp is usually considered as a simulant for chemical warfare agents (cwas). for this purpose fluorescence quenching, resonance light scattering (rls), synchronous, three-dimensional fluorescence spectroscopy and molecular dynamics (md) simulation were emplo...

Amiloride-sensitive Na+/H+ exchange in plasma membrane vesicles prepared by sucrose density gradient centrifugation of mitochondria-rich posterior gill cells in two species of crabs (Callinectes sapidus and Carcinus maenas) was examined by acridine orange fluorescence quenching. Sodium-loaded vesicles injected into sodium-free incubation medium (pHout = pHin) caused a quench in fluorescence ind...

An impaired fat oxidation has been implicated to play a role in the etiology of obesity, but it is unclear to what extent impaired fat mobilization from adipose tissue or oxidation of fat is responsible. The present study aimed to examine fat mobilization from adipose tissue and whole body fat oxidation stimulated by exercise in seven formerly obese women (FO) and eight matched controls (C). Li...

Recent studies on the diazotrophic cyanobacterium Trichodesmium erythraeum (IMS101) showed that increasing CO(2) partial pressure (pCO(2)) enhances N(2) fixation and growth. Significant uncertainties remain as to the degree of the sensitivity to pCO(2), its modification by other environmental factors, and underlying processes causing these responses. To address these questions, we examined the ...

The effect of various parameters (pH, irradiation time, nanophotocatalyst dosages and temperature) on photocatalytic degradation of Direct Red 23 (DR 23) and Direct Brown 166 (DB 166) using pure InVO4 and InVO4-TiO2 nanocomposite were investigated under visible light irradiation. InVO4 and InVO4-TiO2 wer...

A warm (20 to 15 Celsius day or night) preconditioning treatment enhanced cold acclimation of Cornus stolonifera bark under short-day conditions when plants were preconditioned for at least 4 weeks. Warm preconditioning inhibited the acclimation of plants subjected to long photoperiods. Removing leaves from plants exposed to low temperatures and short days inhibited acclimation. Removal of buds...
