Influence of germination techniques on sprout yield,biosynthesis of ascorbic acid and cooking ability,in chickpea (Cicer arietinum L.)

Effects of germination time and illuminations on sprout yield, biosynthesis of ascorbic acid, cooking ability and moisture accumulation in chickpeas were significant (p ? 0.01). Green light had the highest promoting effect on the ascorbic acid level (40.59 mg/100 g) as compared to other illuminations but significantly reduced the sprout yield (188.6 g) as compared to dark, fluorescence and γ-rays illuminations with significantly high sprout yield (196 g) and imbibing moisture (51%). Cooking time was reduced by 43% due to γ-rays in un-soaked seed. Cooking time increased in all treated chickpea samples after 24 h germination and thereafter decreased significantly. Red light significantly increased the cooking time (68.44 min) followed by fluorescent (64.5 min), yellow (61.8 min) and green light (60.9 min). The results indicated that germination of chickpea under green light was an effective process in enhancing ascorbic acid content while dark, fluorescence and γ-rays were effective in promoting sprout growth and to some extent biosynthesis of ascorbic acid.

Pediatric flexible bronchoscopy

Between 1993-1996, 200 pediatric flexible bronchoscopies were performed. Indications were: chronic cough (158 children), persistent pulmonary infiltrates (89), recurrent stridor (28), suspected tracheobronchial foreign body (20), suspected tuberculosis (17) and hemoptysis (3). Some children had more than 1 indication. 124 patients were boys (mean 4.18 +/- 2.86 years; range 1 month-15 years) and 76 were girls (mean 4.39 +/- 2.7 years; range 4 months-15 years). The procedure included direct vision recorded by video-camera and bronchoalveolar lavage; the lavage fluid was sent for culture, Gram and Ziehl-Nielsen strains and for cytology. There were a few minor side effects: mild stridor which resolved within a few hours (10 children) and transient fever (3). This simple, flexible instrument was effective and helpful in the diagnosis and treatment of children with respiratory symptoms in a secondary hospital facility.

FtsY, the prokaryotic signal recognition particle receptor homologue, is essential for biogenesis of membrane proteins

In mammalian cells, many secretory proteins are targeted to the endoplasmic reticulum co-translationally, by the signal recognition particle (SRP) and its receptor. In Escherichia coli, the targeting of secretory proteins to the inner membrane can be accomplished post-translationally. Unexpectedly, despite this variance, E. coli contains essential genes encoding Ffh and FtsY with a significant similarity to proteins of the eukaryotic SRP machinery. In this study, we investigated the possibility that the prokaryotic SRP-like machinery is involved in biogenesis of membrane proteins in E. coli. The data presented here demonstrate that the SRP-receptor homologue, FtsY, is indeed essential for expression of integral membrane proteins in E. coli, indicating that, in the case of this group of proteins, FtsY and the mammalian SRP receptor have similar functions.     

Phenolic constituents in major fractions of tropical rapeseed

Phenolic constituents in major fractions such as seed, cotylendons and hulls of commercial rapeseed varieties Ganyou-5, Westar, Raya-brown and Raya yellow grown under tropical conditions in Pakistan, were determined. Quantitative determination in percentage of sinapine, catechin, tannic acid and total phenolics as well as in absorption units at 550 nm of procyanidine, proanthocyanidine and flavan-4-ols in relation to different extractants such as methanol, methanol-HCl and their totals, were made. These varieties and their fractions widely varied in different phenolic constituents in respect of extractants used. Hulls of all cultivars contained higher levels of catechin, procyanidine, pronanthocyanidine and flavan-4-ols while lower amounts of sinapine, tannic acid and total phenols than the cotylendons. Cotylendons and hulls in seeds of raya-brown were exceptionally high in procyanidine.     

Soluble soybean polysaccharide/TiO2 nanocomposites: Biological activity,release behavior,biodegradability, and biosafety

This study aimed to produce and characterize eco-friendly SSPS nanocomposites incorporated with various concentrations of TiO₂ nanoparticles (NPs) (1%, 3%, and 7%). The antimicrobial activity of the nanocomposite films against five strains of pathogenic bacteria was examined. Salmonella typhi PTCC 1609 was the most sensitive species to TiO₂ NPs at concentrations equal to the synthetic antibiotic. The migration of TiO₂ to ethanol and acetic acid, as two food simulants increased when the initial nano-TiO₂ content increased. The release profiles for TiO₂ in two simulants of ethanol and acetic acid indicated a non-Fickian release, and the release kinetics were concentration-dependent. SSPS/TiO₂ nanocomposites degraded easily and thus have the potential to be applied as an eco-friendly packaging system. Oral administration of doses of 1, 12.5, 25, 50, and 75 mg/kg TiO₂ revealed that the dose of 50 and 75 mg/kg increased malondialdehyde (p < .001) concentration in the liver tissue. In addition, it decreased glutathione (p < .001) concentration in the liver tissue.     

A Reliable Stochastic Numerical Analysis for Typhoid Fever Incorporating With Protection Against Infection

In this paper, a reliable stochastic numerical analysis for typhoid fever incorporating with protection against infection has been considered. We have compared the solutions of stochastic and deterministic typhoid fever model. It has been shown that the stochastic typhoid fever model is more realistic as compared to the deterministic typhoid fever model. The effect of threshold number T* hold in stochastic typhoid fever model. The proposed framework of the stochastic non-standard finite difference scheme (SNSFD) preserves all dynamical properties like positivity, bounded-ness and dynamical consistency defined by Mickens, R. E. The stochastic numerical simulation of the model showed that increase in protection leads to low disease prevalence in a population.
