Outlook threat at the future climate changes on livestock resources

Food availability is the most important issue that takes the priority places in the policies of all countries all over the world. Recently, more attention has been paid to livestock because of their ability to produce meat and milk, as well as it has a significant source of income for small holders and an economic contributor to the gross domestic product. Climate changes induced physiological stress, which is one of the complex factors making livestock management and husbandry challenging in many geographical locations in the world. Increased body temperature or heat stress will cause production losses in livestock and impact on their ability to maintain normal function. There is considerable research evidence that showed significant decline in animal performance when subjected to heat stress. Heat stress inflicts heavy economic losses on livestock production. The effects of heat stress is evident in feed consumption, production efficiency in terms of milk yield or weight gain per unit of feed energy, growth rate, and reproductive efficiency. The aim of this article is to discuss increasing food production to ensure food security for nearly 8 billion people, without causing further environmental damage that can be achieved by transforming systems and adopting sustainable livestock practices within a changing climate.

Calcemia, Vitamin D and seasonal influences in preeclampsia in Goma

Background: The etiology of preeclampsia remains less well known. It is noted that low vitamin D levels are associated with a high risk of preeclampsia (PE). Calcium (Ca2+) levels during pregnancy appear to be involved in pregnancy-induced hypertension. Recent studies indicate that serum calcium levels may have a role in preeclampsia. Vitamin D promotes absorption of proper concentration of calcium in the blood which helps to lower blood pressure. The complications associated with calcium deficiency during a normal pregnancy are numerous and have not been extensively studied in Goma. Objective: To assess blood calcium levels (ionic and total) in preeclamptic women and to analyse the seasonal influence on preeclampsia in Goma. Method: A prospective case-control study (without matching) of 190 pregnant women without cardiovascular or endocrine diseases for a case-control ratio of 1∶1 was conducted in six hospitals in Goma. Blood ionogram was performed by an automated system directly after blood sampling and vitamin D was measured using enzyme-linked immunosorbent method. Results: The mean ionised calcium level in preeclamptic woman was 1.24±0.16 mmol/L (0.48-1.59) compared to 1.27±0.17 mmol/L (0.88-2.30) in normal pregnant woman (p=0.214). A slight negative correlation between blood calcium and blood pressure was observed in pregnant women. Low vitamin D levels were associated with preeclampsia. Hypovitaminosis D in the preeclamptic group was more observed during the rainy season than during the dry season. Pregnancies complicated by PE were from fertilisations occurring during the rainy season while the dry season was characterised by a high admission of preeclamptics. Conclusion: The study found that preeclamptic women in Goma had hypocalcemia. There was also a weak negative correlation between blood pressure and serum calcium levels. The majority of preeclamptics were diagnosed during the dry season, while conception with a PE complication occurred during the rainy season. As this is a first study in this area for the Great Lakes region of Africa, a more in-depth study with a larger sample size is desired.

Comparative antimicrobial activity of Cymbopogon citratus essential oil and thiosemicarbazones derived from this oil

Introduction: The presence of microbes in our environment is always a permanent public health problem. In this context, research on natural treatment, less expensive and accessible to fight these microbial germs would be beneficial. Methods: During this work, molecules of thiosemicarbazones due to their numerous biological activities were hemi-synthesized in situ in the essential oil of Cymbopogon citratus in order to evaluate their antimicrobial activities. Results: Analysis of the essential oil extracted by hydrodistillation revealed the presence of 72.91% of citral. Citralthiosemicarbazone (CThio) and citral 4-phenyl-3-thiosemicarbazone (CPthio) were hemi-synthesized in this oil with interesting yields of 83% and 91%, respectively. After purification and confirmation of the structures of these molecules, the three substances were tested on eleven strains of microbes. Determination of the inhibition diameters showed that the activity of the essential oil is best in over 80% of strains. However, the largest diameter of inhibition (26 mm) was noted with CPthio against Salmonella typhi R 30951401. The determination of the minimum inhibitory concentrations showed that the oil remains more active with the smallest value of 0.3125 mg / ml against Micrococcus luteus. The lower value of minimum bactericidal concentrations was also obtained with the essential oil against Enterococcus foecalis ATCC 29212. Conclusion: The essential oil of C. citratus remains more active in the majority cases. It could be a great alternative in the fight against bacteria, and the advantage is that it remains a natural substance.

Has the time come to consider Omega-3 to be part of treatment protocol for atopy and neurodevelopmental disorder?

Omega-3 fatty acid benefits health throughout life. It is especially important for children’s health. It improves symptoms of children with autism and other neurodevelopmental disorders by improving communication and language development and improving behaviour and cognitive function. It also helps in controlling asthma and other atopic conditions. Adding omega-3 to routine management plan for children with asthma, allergic rhinitis, and neurodevelopment worth consideration.

Relationship between stems moisture to medical (Senecio L.) and elevation in Shan County

A key plant species (Senecio L.) not only is a vital multilevel functional medicinal material of indications of respiratory tract infections, tonsillitis, pharyngitis, pneumonia, conjunctivitis, enteritis, dysentery, but also it is a widely distributed wide plant species. This plant species is widely distributed elevation from 500m to 1500m in six landscapes in Shan County of China. However, understanding dynamics of stems moisture of the plants is difficult along elevation. Herein showed that relations between stems moisture of the species and elevation is a significant positive connection from 500m to 1000m (P<0.01) as well as relationships between stems moisture of this species to elevation is a significant negative connection from 1000m to 1500m (P<0.01). This study provides six types and eco-adaptation for finding new species. Therefore, this study has theoretical and practical significance for plants protection along elevation and environmental gradient over the spatial-temporal-environmental-disturbance scales (STEDS) in the multilevel green space diversity.

Effect of processing and preservation on L-ascorbic acid content in commercially cultivated jute leaves

Vitamin C, also known as ascorbic acid is essential nutrients that cannot produce in human body and meet up through diet. Jute leaves contain L-ascorbic acid. The amount of L-ascorbic is unknown in different varieties developed by Bangladesh Jute Research Institute. L-ascorbic acid content is affected by cooking or processing and preservation. Therefore, the experiment was conducted to investigate the content of vitamin C in the fresh jute leaves as well as the effect of cooking and preservation methods on L-ascorbic acid content in jute leaves. Fresh jute leaves of different varieties contain different amount of L-ascorbic acid 0.39g/10g to 0.64g/10g in Corchorus olitorius and 0.64g/10g to 0.92g/10g in Corchorus capsularis. C. capsularis contain more amount of L-ascorbic acid than the C. olitorius. Jute leaves of C. olitorius retain 95% L-ascorbic acid and C. capsularis retain 62% L-ascorbic acid after 15 min of boiling. Vinegar soaking leaves release more L- ascorbic acid by 5 min than the fresh leaves and then the L-ascorbic acid content was reduced by 15 min in both the species. Spraying vinegar treatment releases more L-ascorbic acid and increasing up-to 30 min treatment. Both oven dried and cold dried leaves retain small amount of L-ascorbic acid. L-ascorbic acid content was reduced in preserved jute leaf tea and soup powder also in both species. Usually, leafy vegetables are cooked before consumption and sometimes preserved vegetables are consumed when fresh vegetables may not available. So, this study may be useful to know the actual intake of L-ascorbic acid from the processed or preserved jute leaves.

Dietary fiber and risk of coronary heart diseases

Dietary fiber is the portion of plant-derived food that cannot be completely broken down by human digestive enzymes. Dietary fibers can be grouped generally by their solubility, viscosity, and fermentation, which affect how fibers are processed in the body. Dietary fiber has two main components: soluble fiber and insoluble fiber, which are components of plant foods, such as legumes, whole grains and cereals, vegetables, fruits, and nuts or seeds. Consumption of cereals, vegetable and fruit may lower the risk of coronary heart disease. Coronary heart disease involves the reduction of blood flow to the heart muscle due to build-up of plaque on the arteries of the heart. Dietary fiber makes three primary contributions: bulking, viscosity and fermentation. The bulking effect of some fibers reduces constipation and the risk of colon disease because they absorb water, which increases bulking and promotes regularity. Viscosity effects on fibers reduce the absorption of cholesterol and other nutrients because of the formation of gels that attenuate postprandial blood glucose and lipid rises. The formation of gels also slows gastric emptying, maintaining levels of satiety and contributing towards less weight gain. In the fermentation process, the bacteria GIT helps to digest fiber through a process of microbial fermentation to generate short chain fatty acids like acetate, propionate and butyrate. Butyrate binds to G-protein coupled receptors on the brush borders of intestinal lining and trigger a signal cascade that release GLP-1 and PYY. These peptides behave like hormones to trigger satiety. One of the reasons for eating fiber rich foods is because they promote satiety and prevent uncontrollable quest for food. People that eat food low in fiber experience over feeding issues. When people over eat they consume more calories leading to weight gain and that contributes to obesity. Obesity is the accumulation of fats in fat tissues. Excess fats are converted to cholesterol (LDL) which accumulates on the walls of the arteries and prevent the flow of blood to the heart. This is prevented when an individual consumes foods rich in fiber.
