Sivagnanam Silambarasan, Alisa S Vangnai
This study focused on rhizospheric yeast capable of degrading a priority pollutant, 4-nitroaniline (4-NA), under drought stress. Candida sp. AVGB4 (AVGB4) inhabiting in soil was isolated and characterized with plant-growth promoting (PGP) traits. 4-NA-dependent growth kinetic and biodegradation kinetics were analyzed and revealed 4-NA complete degradation and tolerance property. AVGB4 proliferation, PGP activities, and 4-NA degradation activity were well maintained under drought stress induced by PEG-6000 incorporation, and could be strengthened in the presence of succinate, an organic compound generally found in plant root exudates...

Phosphorus (P) is one of the most important nutrients for phytoremediation of arsenic (As)-contaminated soils. In this study, we demonstrated that As-hyperaccumulator Pteris vittata was efficient in acquiring P from insoluble phosphate rock (PR). When supplemented with PR as the sole P source in hydroponic systems, P. vittata accumulated 49% and 28% higher P in the roots and fronds than the -P treatment. In contrast, non-hyperaccumulator Pteris ensiformis was unable to solubilize P from PR. To gain insights into PR solubilization by plants, organic acids in plant root exudates were analyzed by HPLC...

BACKGROUND: Light's criteria are ratios of pleural fluid to serum total protein (TP), pleural fluid to serum lactate dehydrogenase (LDH) and pleural fluid LDH to the upper reference limit for serum LDH. They are used to classify pleural effusions into an exudate or transudate when pleural fluid protein is 25-35 g/L. We evaluated the impact of between analytical platforms on the classification of pleural effusions using Light's criteria. METHODS: Light's criteria were used to classify pleural effusions with fluid TP between 25 and 35 g/L into exudate and transudate...

BACKGROUND: Cataract and age-related macular degeneration (AMD) are common causes of decreased vision that often occur simultaneously in people over age 50. Although cataract surgery is an effective treatment for cataract-induced visual loss, some clinicians suspect that such an intervention may increase the risk of worsening of underlying AMD and thus have deleterious effects on vision. OBJECTIVES: The objective of this review was to evaluate the effectiveness and safety of cataract surgery compared with no surgery in eyes with AMD...

Purpose. To report unusual presentation of type 1A idiopathic macular telangiectasia (IMT). Methods. Two middle-aged women with bilateral IMT were examined. Results. Both patients presented with a gradual vision loss in both eyes. Fundus examination was unremarkable in one case and showed small macular telangiectasia in both eyes in the other case. Fluorescein angiography (FA) revealed early bilateral macular punctuated hyperfluorescence corresponding to the dilated capillaries in both cases. FA and fundus examination confirmed also the absence of vascular abnormalities in the middle or anterior fundus periphery in one case...

In thoracic surgery, a thoracic drain is always inserted after the surgical procedure. Repair of the wound after removal of the thoracic tube is performed postoperatively, but no universally standard methods currently exists for this tube removal. Here we report a technique using triclosan-coated sutures that is used in thoracic surgery in our hospital. There are several advantages of this technique. First, there is no need for stitches removal on follow-up. Second, it prevents the leakage of pleural exudate because of the tight two-layer sutures...

A 65-year-old Caucasian male presented to the eye emergency department with bilateral significant visual loss. He was otherwise healthy with no significant past medical history. Ophthalmic history was significant for chronic open-angle glaucoma, for which the patient was using latanoprost once daily to both eyes. There was no preceding history of trauma or ocular surgery and the patient was emmetropic. Two weeks prior to his presentation, he reported a headache, which settled spontaneously. Slit-lamp examination demonstrated bilateral keratic precipitates, bilateral significantly shallow anterior chamber, and bilaterally normal intraocular pressures of 16 mm Hg...

Streptococcus equi ssp. zooepidemicus (S. zooepidemicus) is responsible for peritonitis, septicemia, meningitis, arthritis and several other serious diseases in various species. Recent studies have demonstrated that CD44 is implicated in the process of host defense against pathogenic microorganisms. In the present study, the role of CD44 in the host response to S. zooepidemicus infection was investigated in a mouse model. Upon intraperitoneal infection with S. zooepidemicus, the expression of CD44 on the peritoneal exudate cells from wild-type (WT) mice was increased...

The objective of this study was to improve the rheological (storage modulus G'; phase angle δ) and textural (hardness; breaking force) properties of nitrite-cured sausage batters prepared from pale, soft, exudative (PSE) pork with microbial transglutaminase (TG) using isolated myofibrillar protein (MP) or MP extracted by sodium tripolyphosphate (TPP) as substrates. While TG alone significantly enhanced G', δ and hardness, its combination with TPP was more pronounced as these product quality parameters were increased to the level equal to that of the counterpart batter made from normal (red, firm, non-exudative, RFN) pork...

Periprosthetic inflammatory osteolysis and subsequent aseptic loosening are commonly observed in total joint arthroplasty. Other than revision surgery, few approved treatments are available for this complication. Wear particle-induced inflammation and macrophage polarization state play critical roles in periprosthetic osteolysis. We investigated the effects of curcumin, a polyphenol extracted from Curcuma longa, on titanium (Ti) particle-induced inflammation and macrophage polarization in vitro using the murine cell line RAW 264...

An ideal wound dressing ensures a moist environment around the wound area and absorbs exudates from the wound surface. Topical application of bromelain to incised wounds has been shown to reprogram the wound microenvironment to promote effective tissue repair. Combining the characteristics of hydrogels and bromelain is therefore of great interest. Herein, we describe the development of a hydrogel, formulated using alginate and Arabic gum, for bromelain loading and release. The hydrogel formulation was evaluated using response surface methodology, considering the pH value and the concentration of alginate and Arabic gum...
