Chitosan is a well-known subjectof researchbecause of its beneficial properties, including its antibacterial and fungicidal activity, as well as its effect on plant physiology. One of the maindifficulties in agricultural chitosan implementation is the poor solubility of high molecular chitosan in water. Reducing themolecular weight of chitosan by acid hydrolysis increases its solubility. This research studied the effect of chitosan hydrolysate on the germination and development ofSolanum lycopersicum L. plants. Theeffects of chitosan hydrolysate on seed germination, shoot development in the first week of development and in the first month of development were evaluated. According to the results, high concentrations of chitosan hydrolysate completely inhibited seed germination. However, short-term treatment by high concentrations of chitosan hydrolysate stimulatedthe development of seedlings, leading to substantially longerroots. Regular root application of high concentrations of chitosan hydrolysate inhibited plant development. Keywords: chitosan hydrolysate, chitosan, plant growth regulators, plant germination

Wool scouring effluent (WSE) contains high concentrations of wool grease emulsified by non-ionic surfactants (nonylphenol polyethoxylates – NPEO). The short-term treatment (1-7 days) of this effluent with anaerobic bacteria resulted in partial grease flocculation. However the efficiency of this process varied largely (30% to 80%) with the source of wool scouring effluent used. The concentration of free surfactant, rather than total surfactant, was found to be the likely reason for the variation in efficiency. In order to elucidate the mechanisms of anaerobic biological flocculation a detailed surfactant analysis was performed. This revealed that anaerobic microbes (taken from sludge of a municipal wastewater treatment plant) had an ability to partially degrade NPEO by shortening the hydrophilic ethoxylate chain causing coagulation and subsequent flocculation of wool grease from the liquor.

Recently, many studies have been conducted to discover or improve cancers treatment. The current study aims to investigate the anticancer effect of thymoquinone, cordyceps, spirulina, ganoderma lucidium, poria cocos, and lion’s mane in four different concentrations 4, 8, 16, and 32 ug (equivalent to 1 mg/mL) in two different time treatments (48 and 96 hours) on human nasal epithelial cell line RPMI 2650. By using cell culture cytotoxicity techniques and assay, the highest anticancer effect on RPMI 2650 was obtained by thymoquinone. The lowest anticancer effect was demonstrated by poria cocos and cordyceps. However, these two medications showed higher anticancer effect when given in short-term treatment (48 hours) compared to long-term treatment (96 hours). Ganoderma lucidium and spirulina showed better impact than poria cocos, cordyceps, and lion’s mane in term of cells cytotoxicity. Mild to moderate antineoplastic effect was seen by utilizing lion’s mane treatment compared other drugs. Therefore, adopting a long-term treatment of high concentrations and doses of thymoquinone, cordyceps, spirulina, ganoderma lucidium, poria cocos, and lion’s mane can be more effective in the treatment of nasal cancer. In conclusion, these drugs were found to be a promising cancer remedy; therefore, they can be utilized as alternative treatment for nasal cancer or any other type of cancer therapy.

Objective: This study sought to determine the correlation between trough plasma amikacin concentrations and urinary normalized kidney injurymolecule-1 (KIM-1) concentrations as an early biomarker of nephrotoxicity in patients with sepsis who are hospitalized in an intensive care unit.Methods: In this pilot study, 12 patients with sepsis were treated with amikacin 1000 mg/day between May 2015 and September 2015. The correlationbetween trough plasma amikacin concentrations measured after the third dose and the elevation of urinary normalized KIM-1 concentrations afterthe third amikacin dose relative to the first/second dose was evaluated.Results: In total, three patients had trough plasma amikacin concentrations exceeding the safe level (>10 μg/ml). Furthermore, eight patientsdisplayed higher normalized KIM-1 concentrations after third dose than after the first/second dose; however, there was no correlation betweentrough amikacin concentrations and the elevation of urinary normalized KIM-1 concentrations (r=0.3, p=0.3).Conclusion: The study results illustrated that short-term treatment with an amikacin dose of 1000 mg/day was generally safe in patients with sepsis.

The Voice

Sophisticated, computer-based instrumentation has become increasingly available to the voice clinician. Yet substantial questions remain regarding its clinical necessity and usefulness. A theoretical model based on the scientific method is developed as a framework that can be used to guide the clinician in the selection and application of instrumental measures. Using the process of hypothesis testing, instrumentation is presented as an integral component of clinical practice. The uses of instrumental measures, and their relevance to long- and short-term treatment goals, are addressed. Clinical examples are presented to illustrate the incorporation of instrumentation and the scientific method into assessment and treatment.
