Knowing the determinant-based disease status of dogs is imperative to keep them healthy by subsequent prevention and control of those diseases; however, such baseline epidemiological information is limited. Therefore, a retrospective cross-sectional study was conducted to estimate the proportional incidence of dog diseases to explore their magnitudes, and we compared them to different levels of intrinsic (age, gender, breed) and extrinsic determinants (season). Purposively, data of a total of 1,557 cases of different diseases were collected from the record book of the Central Veterinary Hospital (CVH), Dhaka, Bangladesh. The proportional incidence was calculated as the proportion of cases of a specific disease among total number of cases of all types of diseases attended the hospital during the study period. Diseases of dog were categorized into infectious, non-infectious, and non-specific. Results showed that the highest proportional incidence was noted in infectious diseases (53.8%) followed by non-infectious diseases (23.4%) and the lowest in non-specific (22.7%) cases. Among them, disease-specific proportional incidence was remarkable in case of mange (9.5%), parvovirosis (8.7%), lacerated wound (8.5%), ectoparasitism (8.3%), helminthiasis (7.8%), and fracture (5.7%). The occurrence of mange varied significantly (p < 0.05) among all studied determinants (age, gender, breed, and season); while significant discrepancies (p < 0.05) in magnitudes of lacerated wound, dystocia, abortion, and gastroenteritis were observed among various groups of age, gender, and breed. Accordingly, dermatitis and orchitis had significant differences (p < 0.05) in proportional incidence amid various levels of age, gender, and season; whilst the burden of parvovirosis and alopecia differed significantly (p < 0.05) amongst different categories of age, breed, and season. The magnitude of otorrhoea showed a significant (p < 0.05) variation among different groups of gender, breed, and season. The proportional incidence of other diseases also varied significantly (p < 0.05) amongst either one or two studied determinants. This study provides a valuable insight about important diseases in dogs, which may serve as useful baseline information for disease prioritization and subsequent planning of effective control and prevention measures against those diseases.

In recent years, attention has been focused on the role of lipoproteins, alterations of cholesterol metabolism and oxidative stress in the molecular mechanism of breast cancer. A role for high density lipoproteins (HDL) has been proposed, in fact, in addition to the role of reverse cholesterol transport (RCT), HDL exert antioxidant and anti-inflammatory properties, modulate intracellular cholesterol homeostasis, signal transduction and proliferation. Low levels of HDL-Cholesterol (HDL-C) have been demonstrated in patients affected by breast cancer and it has been suggested that low levels of HDL-C could represent a risk factor of breast cancer. Contrasting results have been observed by other authors. Recent studies have demonstrated alterations of the activity of some enzymes associated to HDL surface such as Paraoxonase (PON1), Lecithin-Cholesterol Acyltransferase (LCAT) and Phospholipase A2 (PLA2). Higher levels of ma...

These natural antioxidants, especially polyphenols, exhibit a wide range of biological activities including anti-cancer, anti-inflammatory, and anti-atherosclerosis activities. Pomegranate (Punica granatum L.) is a rich source of polyphenolic components. The purpose of this study was to characterize the phenolic composition and flavonoids and anthocyanin content of different parts (peel and aril) of the Sefri variety of pomegranate. Our results showed that Peel extract was richer in these compounds than that of the Arils, especially in Punicalagin (A and B). DPPH free radical scavenging, reducing power (FRAP), β-carotene bleaching, and hydrogen peroxide scavenging assays revealed a greater dose-dependent activity of pomegranate peel phenolic extract (PPPE) compared to pomegranate aril phenolic extract (PAPE). PPPE was also more potent than PAPE concerning its ability to inhibit conjugated diene format...

For the footwear industry, the main environmental impacts are the releasing of volatile organic compounds (VOCs) and solid wastes. The pressure of reducing harm to the environment is coming from both the consumers and the legislation. CO2 and VOCs are hazardous to human health and also trigger serious environment problems, such as ozone layer depletion, offensive odour, photochemical smog, acid rain and many others. Adhesives, finishing products and cleaners contribute to VOCs emissions in the footwear manufacturing industry. VOCs emission may also arise from primers, separating agents, printing inks or finishing pastes. Some most commonly produced VOCs in the footwear manufacturing industry are benzene, toluene, styrene, ethylene, xylene, acetaldehyde, formaldehyde, methyl ethyl ketone, chlorobenzene, phenol etc. All of these cause severe health problems in hum...

Seeds were packed in polythene and cloth bag and stored over 14 months to determine the changes in biochemical composition under ambient condition. Results revealed that total soluble sugar, total soluble protein and oil content of cotton seeds decreased and total free amino acid increased with the increase of storage period. However, decreasing rate of total soluble sugar, total soluble protein and oil content and increasing rate of total free amino acid was slower in polythene bag and faster in cloth bag throughout the storing period. Among the genotypes, BC-0252 showed slower degradation of biochemical composition of stored seeds than that of seeds of other genotypes.

(Pitanga, Surinam cherry, Pitangueira) is native to Brazil and other countries in Northern South America. It is a fast-growing shrub or small tree that grows to six meters and usually produces two crops per year of relatively small (2.5 to 3.0 cm), juicy fruits. The fruits ripen quickly, taking only about six to seven weeks to reach maturity from anthesis. The mature fruit range in color from light to dark red, to almost black, and have flesh of a lighter, similar hue. The juicy sweet-acid pulp encloses one or occasionally more seeds. The fruits, especially the dark purple ones, are an excellent source for antioxidants such as cyanidin-3-glucoside and delphinidin-3-glucoside, as well as xanthophylls such as rubixanthin and lutein. The fruits are also especially rich in the carotenoid lycopene. The pulp is also a good source of calcium and a fair source of phosphorus and iron. The ripe fruits are perhaps the best of the edible eugenias and can be eaten fresh or processed into frozen pulp, juices, jams, jellies, and various other food items. Although the plants prosper in soil with abundant organic matter and a pH of 5.5-6.5, they can grow and fruit in a wide diversity of soils from heavy acid clays to pure sand to high-pH limestone soils. They grow well and produce fruits in full sun or partial shade. They are relatively easy to grow without fertilization although they respond very positively to fertilizer and water applications. Plants come into bearing from seed in about three to four years, although (grafted) improved varieties can produce larger, more flavorful fruits with higher levels of antioxidants one year after grafting. Trials in progress at the University of Hawai'i will provide organic-farming certified and non-organic fertilizer recommendations for small-scale producers. Additional laboratory analysis on chemical and nutritional contents of mature fruits will allow for further selection and development of superior clones. Grafting trials using the improved purple cultivar 'Zill Dark' are yielding good success rates with veneer grafts.

The minimum tillage practices under broadcast and deep band placement methods showed the highest available and total P content in soil after harvesting of maize. Phosphorus was stratified in the topsoil with zero tillage along with broadcasting and surface band applications but the CT and DT practices under broadcast and deep band placements resulted in the almost similar distribution of P with soil depth up to 24 cm.
