...PHYSIOLOGICAL STUDIES OF THE FRUITS OF THE PINEAPPLE [ANANAS COMOSUS (L.) MERR.] WITH SPECIAL REFERENCE TO PHYSIOLOGICAL BREAKDOWN ERSTON V. MILLER Received July 17, 1950 Introduction Physiological breakdown of the fruits of the pineapple [Ananas comosus (L.) Merr.] is characterized by a darkening of the flesh of the fruitlets, beginning near their attachment to the core in a region an inch or two above the base of the fruit. The-disorder progresses upward and outward, subsequently involving all of the fruitlet except the ovary and a layer approximately one quarter inch deep below the skin. Only in advanced stages do the surface of the fruit and the core become involved. Hence in most fruits there may be no external symptoms of the disorder. Severe cases of physiological breakdown are frequently discovered in pineapples that appear normal and attractive from the exterior. The disorder is not a form of over-ripeness as is true of "internal breakdown" of apples. One of the commonest causes of physiological breakdown is exposure of the fruits to relatively low temperatures. The disorder has been observed in Florida in the fruits that were induced to ripen during the winter months by forcing the bloom with acetylene gas during "off season." Physiological breakdown has been reported to occur under similar conditions in Australia (3). Also pineapples harvested during the summer months may develop breakdown during storage or transit if holding temperatures are...

...basic structure of chlorites allows for various compositions(Grim,1962). Members are differentiated by substitutions within the octahedral layer and the tetrahedral or octahedral positions of the mica-like layer. The arrangement of hydroxide and 2:1 sheets stacked in the z-direction defines the polytype of chlorite. There are theoretically six possible layer interlayer assemblages in either semi-random or regular "one-layer" polytypes. Of these six polytypes, four have been observed in nature (Partice De Caritat ect. 1993): clinochlore (Mg,Fe2+)5Al(AlSi3O10)(OH)8, chamosite (Fe2+,Mg)5Al(AlSi3O10)(OH)8, nimite (Ni,Mg,Al)6((Si,Al)4O10)(OH)8, and pennanite Mn52+Al(AlSi3O10)(OH)8. Provenance Chlorite is widespread throughout the world, often found in low- to medium-grade regional metamorphic rocks and as a secondary mineral to mafic silicates in igneous, metamorphic, and sedimentary rocks. It is an occasional constituent of igneous rocks, in most cases probably forming secondarily by deuteric or hydrothermal alteration of primary ferromagnesian minerals, such as mica, pyroxene, amphibole, garnet, and olivine (Bailey, S. W., 1988). A ubiquitous product of low-grade metamorphism, chlorite influences a wide variety of rocks of different formation age such as in Cambrian basaltic vesicular lavas, early Oligocene sandstones and greywackes with andesitic volcanic clasts (Lopez-Munguira et al., 2002) (Schmidt and Levi, 1999)....

...Research Paper Diagnosis and Treatment of Alzheimer’s Disease: Current Challenges Prepared by Ms. Rawan Al-Juweed Introduction Alzheimer’s disease (AD), the most common form of dementia, is a degenerative disorder of the brain that leads to memory loss1. AD affects 5.3 million Americans and is the seventh leading cause of death in the United States. There are two main forms of the disease. Familial AD affects people younger than 65, accounting for nearly 500,000 AD cases in the United States alone1. The remainder of AD cases occur in adults aged 65 and older and is classified as sporadic AD. The prevalence of AD varies among many different factors, including age, co-morbidities, genetics, and education level. There is no way to definitively diagnose AD without performing an autopsy. There is no cure for AD, however promising research and development for early detection and treatment is underway. Abstract Alzheimer’s disease was discovered in 1906 by Alois Alzheimer, a German neurologist and psychiatrist2. The disease was initially observed in a 51-year-old woman named Auguste D. Her family brought her to Dr. Alzheimer in 1901 after noticing changes in her personality and behavior. The family reported problems with memory, difficulty speaking, and impaired comprehension. Dr. Alzheimer later described Auguste as having an aggressive form of dementia, manifesting in memory, language and behavioral deficits3. Dr. Alzheimer noted many abnormal symptoms, including difficulty...

...TOP TEN CAUSES OF POISONING Section 2-D |Roña, Diandra Krystle B. | |Rosales, Aileen L. | |Rosaura, Franz D. | |Roxas, Marie Florence S. | |Rubio, Hannah Alexis O. | |Rugay, Jesus Emmanuel R. | February 1, 2012 POISONING Poisons are substances that cause disturbances in living organisms and do so by some biologic or chemical reaction in nature. For decades, the use of different substances for various applications lead to the discovery of potential toxic substances that may have caused injurious effects. Poisoning commonly occurs thru ingestion and usually, it was unintentional. Acute toxicity is the single exposure or multiple exposures for short periods to the substance causing the injury. Symptoms may be rapid and are in close relation to the toxic agent. On the other hand, chronic toxicity are caused by repeated or multiple exposure for longer periods to the poison. Signs and symptoms of chronic toxicity may appear even after several years upon the initial exposure. ADULT TOP TEN TOXICITIES 1. CAUSTICS Caustics are strong acids and alkali that when ingested can cause tissue injury by chemical reaction. They damage the tissues by accepting a proton (alkaline substance)...

...[pic] The forty-eight hours exposure we had at Cotabato Regional and Medical Center opened the door of opportunity to experience things that broadened our knowledge and enhanced our skills. We were exposed to different cases of various clients. We became accustomed with the routines in the hospital and interacting with our patients, even with their watchers. We encountered some difficulties and struggles, yet that didn’t hinder us in giving our best to do our job. That exposure gave us an opportunity to handle different cases. With all those we’ve encountered, we chose one to be the subject of our case study. We are presenting to you Bronchial Asthma which is the case of our patient at Medicine Ward Room C whom we will call Mr. Theodore for the purpose of confidentiality. Bronchial asthma is a disease caused by increased responsiveness of the tracheobronchial tree to various stimuli. The result is paroxysmal constriction of the bronchial airways. Bronchial asthma is the more correct name for the common form of asthma. The term 'bronchial' is used to differentiate it from 'cardiac' asthma, which is a separate condition that is caused by heart failure. Although the two types of asthma have similar symptoms, including wheezing (a whistling sound in the chest) and shortness of breath, they have quite different causes. Bronchial asthma is a disease of the lungs in which an obstructive ventilation disturbance of the respiratory passages evokes a feeling of shortness...

BASELINE STUDIES OF THE CLAY MINERALS SOCIETY SOURCE CLAYS: INFRARED METHODS ´ JANA MADEJOVA AND PETER KOMADEL Institute of Inorganic Chemistry, Slovak Academy of Sciences, SK-842 36 Bratislava, Slovakia INTRODUCTION Infrared (IR) spectroscopy has a long and successful history as an analytical technique and is used extensively (McKelvy et al., 1996; Stuart, 1996). It is mainly a complementary method to X-ray diffraction (XRD) and other methods used to investigate clays and clay minerals. It is an economical, rapid and common technique because a spectrum can be obtained in a few minutes and the instruments are sufficiently inexpensive as to be available in many laboratories. An IR spectrum can serve as a fingerprint for mineral identification, but it can also give unique information about the mineral structure, including the family of minerals to which the specimen belongs and the degree of regularity within the structure, the nature of isomorphic substituents, the distinction of molecular water from constitutional hydroxyl, and the presence of both crystalline and non-crystalline impurities (Farmer, 1979). The interpretation of the absorption spectra of the Source Clays in the middle-IR (MIR) region (4000– 400 cm 1) given here follows those of Farmer and Russell (1964), Farmer (1974a, 1979) and Russell and Fraser (1994). In addition, reflectance spectra in the near-IR (NIR) region (11,000–4000 cm 1), where overtones...

...clear. An overview of 5 randomized trials investigating aspirin therapy for the primary prevention of vascular disease found a significant beneficial effect of aspirin therapy on the prevention of a first MI, but no significant effects on the risk of stroke or vascular death.4 Although women were included in only 2 of these studies and accounted for only 20% of the population studied, the US Preventive Services Task Force5 and the American Heart Association6 deemed aspirin therapy effective in decreasing the incidence of coronary heart disease in adults of both sexes who are at increased risk. Subsequently, guidelines from the American Heart Association on the primary prevention of cardiovascular disease in women recommended use of low-dose aspirin therapy in women whose 10-year risk of a first coronary event exceeds 20% and consideration 306 Context Aspirin therapy reduces the risk of cardiovascular disease in adults who are at increased risk. However, it is unclear if women derive the same benefit as men. Objective To determine if the benefits and risks of aspirin treatment in the primary prevention of cardiovascular disease vary by sex.

The sensor detected the changes of the surface- rather than the bulk- property and morphology of A36 during corrosion. Thus it was more sensitive than the conventional electrical resistance corrosion sensors. After being soaked in an aerated 0.2 M NaCl solution, the sensor’s normalized electrical resistance (R/R0) decreased continuously from 1.0 to 0.74 with the extent of corrosion. Meanwhile, the sensor’s normalized capacitance (C/C0) increased continuously from 1.0 to 1.46. X-ray...

...FORMULATION AND EVALUATION OF TOPICAL GEL CONTAINING AZITHROMYCIN AND PREDNISOLONE VESICLES FOR TREATING PSORIASIS Sonia Tomar, Tinku Singhal, ABSTRACT Psoriasis is a chronic, autoimmune systemic inflammatory disease, associated with metabolic syndrome, cerebrovascular disease, diabetes and many other diseases. There is various type of psoriasis but most common type of psoriasis is caused by Psoriasis vulgaris. It is characterized by rigid of skin due to increase in the level of cholesterol and fall in the level of ceramide. Apart from that it is associated with an immune system of the body means movement of immune cells from dermis to the epidermis, where they stimulate skin cells (keratinocytes) to proliferate. Various type of drug delivery system are used for the treatment of psoriasis including topical, oral or systemic but gels prepration of azithromycin and prednisolone are more effective in reduction of purities, scaling and hyperkeratosis of psoriasis plaque. Niosomal/Vesicular gel, has been explored extensively for topical application to enhance skin penetration as well as skin retention. Prednisolone and azithroycin together provide effective results in the treatment of psoriasis. Due to high entrapment efficiency and stability, gel prepration (Azithromycin & Prednisolone) reduce the scaly patches and suppression of humoral immunity.

...Proposal for Use of Pseudostem from Banana Tree (Musa cavendish) D. G. FERIOTTI & A. M. IGUTI Maua Institute of Technology, Sao Caetano do Sul, Brazil (danygf85@yahoo.com.br) ABSTRACT This paper presents a proposal for use of pseudostem from the banana tree (Musa cavendish). After banana harvesting, the pseudostems are cut and left in the fields. In order to add value to banana plantation, the pseudostem could be processed into products. Nowadays, the pseudostem fiber has been used mainly in handicrafts. Although studies have shown that the cellulose fiber has suitable features to industry, the yield is low because pseudostem has about 90% of water. This research presents the physicochemical composition of the liquid fraction extracted from pseudostems and proposes an application for it. The following analyses were performed: sugar, protein, fat, solids, sodium, potassium, calcium, magnesium, chloride, tannin, polyphenoloxidase and peroxidase activity, microbiological and pesticides. Once it contains potassium and sodium, the development of a sport drink seemed suitable. The paper presents some social and economical data of Vale do Ribeira region, the main banana producing region of Sao Paulo State. Additionally, some concepts of the banana plantation are reviewed as well as information about sport drink and the new Brazilian law on athlete’s food. Data about its market are also included, and the results of analyses. The results showed that the liquid fraction...
