Food safety training in Texas school foodservice facilities in relationship to the implementation of a HACCP program
No full textDual DegreeThe purpose of this study was to investigate food safety training currently offered in Texas school foodservice facilities in relation to implementation of Hazard Analysis Critical Control Point (HACCP). A survey instrument was developed by the researcher, validated by school foodservice professionals and pilot tested. Online surveys and paper surveys were used to obtain data. Of 525 foodservice directors randomly chosen, 120 completed the survey and results were summarized and statistical analyses were conducted using Pearson's Product Moment Correlation and Analyses of Variance. Food safety training is currently being provided in school foodservice through different methods. A majority of school foodservice directors agreed with the effectiveness of food safety training, had favorable attitudes towards food safety training and faced few barriers to food safety training. Overall, this study concluded that most Texas school foodservice facilities have standard operating procedures and a HACCP plan in place

Predicting neuropathy and reactions in leprosy at diagnosis and before incident events. Results from the INFIR cohort study
No full textBackgroundLeprosy is a disease of skin and peripheral nerves. The process of nerve injury occurs gradually through the course of the disease as well as acutely in association with reactions. The INFIR (ILEP Nerve Function Impairment and Reactions) Cohort was established to identify clinically relevant neurological and immunological predictors for nerve injury and reactions.Methodology/Principal FindingsThe study, in two centres in India, recruited 188 new, previously untreated patients with multi-bacillary leprosy who had no recent nerve damage. These patients underwent a series of novel blood tests and nerve function testing including motor and sensory nerve conduction, warm and cold detection thresholds, vibrometry, dynamometry, monofilament sensory testing and voluntary muscle testing at diagnosis and at monthly follow up for the first year and every second month for the second year. During the 2 year follow up a total of 74 incident events were detected. Sub-clinical changes to nerve function at diagnosis and during follow-up predicted these new nerve events. Serological assays at baseline and immediately before an event were not predictive; however, change in TNF alpha before an event was a statistically significant predictor of that event.Conclusions/SignificanceThese findings increase our understanding of the processes of nerve damage in leprosy showing that nerve function impairment is more widespread than previously appreciated. Any nerve involvement, including sub-clinical changes, is predictive of further nerve function impairment. These new factors could be used to identify patients at high risk of developing impairment and disability

Biomaterials and Medicine
It has been always medical practitioners coming first to identify the need to lead themselves and others towards the best therapy. When patient services emerged, the clinicians themselves were everybody. Dr Gibbon, when he did his first open heart case in 1950’s, he was the perfusionist and perhaps anaesthetist too. To get into its (bio) materials, through a case study, let us take a review of a simple clinical procedure. Wound closure through suturing. Its tribology matrix highlighted below (Figure 1), sketches its journey, clinical demands, scientific solutions and biomaterials thereof. The bottom line, best is still (re)searched
Enhancement of storage life and quality maintenance of papaya fruits using <i style="">Aloe vera</i> based antimicrobial coating
No full text83-89Papaya is one
of the main tropical fruits of India. The desiccation of fruits and perishable
nature of papaya is a major drawback during transportation to distant markets
and storage during glut in the market. Aloe
vera gel, mainly composed of polysaccharides, has been recently explored as
an edible coating owing to its antifungal activity. To improve the performance
of edible coatings, various substances/chemical additives have been
incorporated. Papaya leaf is a potential antifungal agent that could be used as
a bio-based additive, especially, by papaya growing farmers. The present study
was carried out to evaluate the ability of Aloe
gel based antimicrobial coatings to reduce/control the loss of post harvest
fruit quality in papaya and to compare the effects with a natural
polysaccharide-chitosan, an established coating material with antifungal
activity. Freshly harvested papaya fruits were coated with Aloe gel/AG (50%), papaya leaf extract/PLE incorporated Aloe gel (1:1) and 2.5% chitosan. The
coated and uncoated (control) fruits were stored at 30±3°C and 42-55% RH for 15 d. Physical (PLW, fruit size), chemical (pH, titrable acidity and TSS), and
sensory characteristics (colour, taste & firmness); fruit disease index
(FDI), and marketability were analyzed at regular intervals during the storage
period. The coated fruits survived the storage period of 15 d, whereas, all the
uncoated controls decayed within 10 d. The uncoated/control fruits exhibited
significantly greater changes in all the parameters tested. Among the coated
fruits, PLEAG treated fruits exhibited least changes followed by AG and
chitosan coated fruits. The coatings controlled the PLW, ripening process
(chemical changes, colour development and softening of fruit tissue) and decay
to a great extent and thereby extended the shelf life quality of the fruits.
Marketability was also found to be better for PLEAG coated fruits among the 3
coatings, followed by AG and chitosan coated fruits. The effectiveness of AG coating was found to improve on incorporation of
PLE. Shelf life could be further extended in low temperature storage. This is
probably the first study on utilizing a natural alternative such as Aloe-gel and PLE to extend shelf life
quality in papaya. On the basis of the over all physiological changes, Aloe gel based antimicrobial coating has
been identified as a suitable method to extend the shelf life of papaya fruits

Management practices to improve the use efficiency of nutrients and water in a sandy soil under rice based cropping system
No full textProductivity of coarse textured sandy soil is relatively low due to its extreme permeability which permits deep percolation of water and nutrients. Onattukara sandy tract is a fluvial and marine sand area of Alappuzha and Kollam districts of Kerala state in India which covers about 72550 ha. The cropping system practiced here is Rice-Rice-Sesame. Because of their low water holding capacity and high susceptibility to leaching of mobile nutrients, crops grown in these soils are more prone to water and nutrient stresses leading to low crop yields. For such soils reduction of seepage losses by reducing the relative proportion of macro pores through compaction has an important beneficial effect on growth and yield of rice (Oryza sativa) and Sesame (Sesamum indicum). Along with compaction, application of farm yard manure, coir pith and kayal silt will definitely improve soil physical properties such as water holding capacity, nutrient retention and soil structure. In order to alleviate the physical constraints of sandy soil and to enhance the nutrient and water use efficiencies, soil compaction along with the addition of farm yard manure, coir pith (waste material from coconut husk)and kayal silt( lake sediments) were tried to develop a new technology.The field experiment is been conducted in a rice-rice-Sesame cropping system for three consecutive years at the Rice Research Station, Kayamkulam, and Kerala. The soil in this tract is sandy kaolinitic isohyperthermic psammaquent, highly permeable leading to high loss of nutrients and water. Design of the experiment was Factorial Randomized Block Design. The treatments consisted of the following factors-C0-No compaction;C1-Compaction with 400kg roller passing 4 times;F0-No farm yard manure;F1-2.5 t FYM;F2-5t FYM ha-1;S0-No kayal silt;S1-5 t ha-1Kayal silt;P0-No coir pith;P1-5 t ha-1coir pith(sieved).There are 18 treatments consisting of combinations of all the above factors excluding the combinations of S1 and P1 with other factors. After harvest of each crop soil physical properties, chemical properties, yield of crop and uptake of nutrients were analyzed using standard procedures. The first crop (rice), second crop (rice) and third crop (Sesame) recorded higher yield in compacted treatments when compared to non-compacted treatments. Compacting the soil of Onattukara sandy tract using 400kg roller passing 4 times at Procter moisture level with farmyard manure, coir pith and kayal silt has resulted in improvement of physical fertility of the soil. In the first crop rice the highest yield (3.15tha-1) was recorded by C1F1S0P1 (compaction+2.5t FYM+5t coir pith) treatment where as the same treatment without compaction gave only 1.60 t ha-1only half of the former.C0F0S0P0 treatment recorded a hydraulic conductivity of 6.86 cm/hr where as the same treatment with compaction reduced hydraulic conductivity to about half (3.24 cm/hr).The total uptake of N, P and K was increased significantly in compacted plots. The treatment C1F1S0P1 recorded lowest hydraulic conductivity in surface and sub surface layers and highest nutrient uptake. The yield increase in this treatment was due to reduction in leaching loss of nutrients by lowering the hydraulic conductivity and thereby increased uptake of nutrients. In second crop rice, the highest grain yield and straw yield was noticed in the C1F2S0P1 treatment. Highest root volume, leaf area index and N, P, K uptake were recorded by this treatment. Lowest hydraulic conductivity was also registered by this treatment. All these factors contributed for obtaining maximum yield in this treatment. Soil physical properties like bulk density, soil strength, mean weight diameter, micro porosity, water holding capacity and field moisture content were increased in compacted plots. Addition of FYM and coir pith enhanced the structural and moisture retention properties of soil. Compaction of coarse textured soils using 400 kg roller passing 4 times along with 5t ha-1 FYM and 5t ha-1 coir pith improved the soil physical properties, nutrient uptake and in turn yield of crops under rice based cropping system
