The rapid spread of bacteria expressing multi-drug resistance propels the search for new antibacterial agents. The present study was designed to evaluate the antibacterial activities of the methanol extracts from Beilschmiedia obscura and six other Cameroonian plants against a panel of twenty nine Gram-negative bacteria including Multi-drug resistant (MDR) phenotypes. The phytochemical investigations of the extracts were carried out according to the standard methods and the liquid micro-dilution assay was used for all antibacterial assays. Phytochemical analysis showed the presence of alkaloids in all studied extracts. Other chemical classes of secondary metabolites such as anthocyanines, anthraquinones flavonoids, saponins, tannins, sterols and triterpenes were selectively detected in the extracts. The extract from the fruits of Beilschmiedia obscura, Pachypodanthium staudtii leaves and Peperomia fernandopoiana (whole plant) displayed the best spectrum of activity with MIC values ranging from 16 to
Twenty-five species of Lauraceae cuticle are described from 120 fossil-bearing samples from two Early Miocene basins in southern New Zealand; the St Bathans Paleovalley of the Manuherikia Group, and the Gore Lignite Measures of the East Southland Group. The genera Endiandra and Cryptocarya are identified, which are no longer in the extant flora of New Zealand, and Beilschmiedia and Litsea which are in the extant flora. In the St Bathans Paleovalley it is likely that at least 22 species were growing as part of a single broader community. The presence of Lauraceae at this latitude in New Zealand and their high diversity clearly implies warmer temperatures than currently exist at lowland locations at that latitude today, which lie to the south of the existing limit of the family.. ...
Cassytha is a genus of some two dozen species of obligately parasitic vines in the family Lauraceae. Superficially, and in some aspects of their ecology, they closely resemble plants in the unrelated genus Cuscuta, the dodders. When fruit and flowers are absent in the field, the physical resemblance is so close that few people without technical training can tell them apart. In this respect and in their ecology the two genera present a spectacular example of convergent evolution. In its divergence from habits typical of the Lauraceae, Cassytha also presents examples of mosaic evolution Several species of Cassytha are regarded as pests in various regions, though as a rule they are not as serious a problem as the true dodders. Some even yield a welcome harvest of fruit, or are valued for their perceived medicinal or aphrodisiac properties, partly because, like many members of the Lauraceae, some are fragrant when bruised. Their stems make useful strings for construction of thatched roofs and ...

Quetzals are known to eat up to 41 species of fruit however much of their biology seems tied not to any one species but to the fruiting patterns of a single family, the Lauraceae (Wheelright, 1983). Quetzals are altitudinal migrants. They breed and nest in montane forests and migrate to lower altitudes where they remain for the non-breeding season (Powell and Bjork, 1994). Breeding occurs during the peak of fruiting in the Lauraceae and emigration occurs when there is a relative paucity of lauraceous fruits even though other species of fruits are available (Wheelright, 1983). Quetzals morphology and geographical distribution also reflect their dependence on the Lauraceae. The Trogonidae and Lauraceae have possibly been in association since the late Cretaceous or early Tertiary, both families are pantropical with present centers of diversity in the Neotropics and Southeast Asia (Sibley and Ahlquist, 1990). It has been theorized that the quetzals and Lauraceae (whose fruits they depend on and ...

The salt is probably a mixture of beberine, nectandrine (this is probably identical with sipirine), and other alkaloidal. bodies.. Preparation.-The process for obtaining it is essentially the same as that for sulphate of quinine. The bark is at first freed of tannin and coloring matter by boiling it with carbonate of sodium; it is then exhausted by boiling in water acidulated with sulphuric acid, and the alkaloidal matter is thrown down from the concentrated acid liquor by means of carbonate of sodium. The impure bases thus separated are washed, dissolved, and neutralized with weak sulphuric acid, and the solution is treated with animal charcoal, concentrated, filtered again, and finally evaporated in thin layers in flat vessels. Any excess of acid must be carefully avoided, otherwise the salt will be ...

Stress is related to psychological disorder, but not all the subjects develop this disorder. This happens because they have different ways of acting when faced with stress," explains Gómez. This is her conclusion after filming the performance of all types of mice, analysing it and classifying it in terms of a passive or active strategy. And how do the two strategies differ? For example, if the dominant mouse were to attack, the dominated passive would not even move, whereas the active one would flee. "The passive ones remain still nearly all the time, and as the stress goes on, they become even stiller. The active one is also aware that the stress is very hard and that it cannot get out of it, but it puts up greater resistance," says Gómez. There is also a great difference with respect to how they interact with the group leader. In fact, the one that makes use of the active strategy is interested in what is going on around it, it sniffs the dominant one, and tries to interact with it… ...

This year has been so hard. It has been by far the most difficult despite everything we had already been through. Mae has been witness to too many traumatizing and devastating things. She has sat quietly as doctors have discussed infections, strokes, seizures, cancer, and terrible odds. She has seen her baby sister scream in pain. She has walked beside us the many times Phoebe has been transferred to the ICU. She has seen Jon and I completely broken. She has asked if Phoebe will ever come home. She has watched as Phoebe is sedated. She has wondered out loud if the Phoebe that she loves so much would come back to her after a stroke and fungal infection in the brain caused her to be unrecognizable. She has sat by and held her little sisters hand through days that would cause the strongest people to completely break down. Despite a fungal infection that has left marks and scars on Phoebes skin that are most likely permanent - Mae sees nothing but pure beautiful and brave Phoebe. Unlike some ...

Phoebes latest bone marrow chimerism shows that just 9% of her cells are donor cells and the remaining 91% are leukemia. This is slightly higher than on the last test. The leukemia is now predominantly AML, with some ALL still present. Phoebes blood and spinal fluid remain clear of leukemia and although the bone marrow results are terrible and devastating, Phoebe is not a sick little girl. She is eating, playing, laughing, singing and telling us exactly how she feels. She is often the last person to go to sleep and the first to wake up in the morning and she brings the joy and spunk to our days. She has earned the title of "tiny boss lady" because as joyful as she is, she is also very bossy and determined. At least once a day, I hear Mae tell Phoebe - "you are not the boss of me". Phoebe has so little control over her days that she tries her best to control what she can, including Mae ... and Jon and I too. ...

The pharmacological effects on the cardiovascular system of yangambin, a lignan isolated from Ocotea duckei Vattimo (Lauraceae), were studied in rats using combined functional and biochemical approaches. In non-anaesthetized rats, yangambin (1, 5, 10, 20, 30 mg/kg, i.v.) induced hypotension (−3.5 ± 0.2; −7.1 ± 0.8; −8.9 ± 1.3; −14 ± 2.3, −25.5% ± 2.6%, respectively) accompanied by tachycardia (5.9 ± 0.5; 5.9 ± 1.6; 8.8 ± 1.4; 11.6, 18.8% ± 3.4%, respectively). In isolated rat atria, yangambin (0.1 µM-1 mM) had very slight negative inotropic (Emax = 35.6% ± 6.4%) and chronotropic effects (Emax = 10.2% ± 2.9%). In endothelium-intact rat mesenteric artery, yangambin (0.1 µM-1 mM) induced concentration-dependent relaxation (pD2 = 4.5 ± 0.06) of contractions induced by phenylephrine and this effect was not affected by removal of the endothelium. Interestingly, like nifedipine, the relaxant effect induced by yangambin was more potent on the contractile response induced by KCl 80 mM

However, Hass avocado trees have high yields compared to other varieties and a mature tree can produce over a million blooms. Most Hass trees bloom twice a year and occasionally there is a third bloom. Hass trees start bearing fruit in three to five years and grow from 15 to 30 feet tall. The lifespan of an average tree is several decades.. Unlike other avocados, which have smooth green skin, the Hass avocado fruit has dark green bumpy skin that darkens as it ripens, eventually reaching a very dark shade that is almost black. Like all avocados, Hass avocados ripen only once they are picked from the tree and they can be left on the tree for several months after the fruit has matured.. When it comes to nutritional content, Hass avocados are higher in fat than other varieties, which gives them a richer taste and smoother, creamier texture. 80 per cent of avocados consumed in the world are Hass Avocados, meaning all other varieties make up only a small proportion of the remaining 20 per cent.. There ...
Preheat oven to 350 degrees F. Grease and flour two 8 or 9-inch rounds. Set aside. Sift together all of the dry ingredients except the sugar. Set that aside too. Mix all the wet ingredients together in a bowl, including the super-mashed avocado. Add sugar into the wet mix and stir. Mix the wet with the dry all at once, and beat with a whisk (by hand) until smooth. Pour batter into greased cake tins. Bake for 30 to 40 minutes, until a toothpick inserted comes out clean.. Let cakes cool in the pan for 15 minutes, then turn out onto cooling racks to cool completely before frosting with avocado buttercream. For the buttercream, peel and pit the soft avocados. Its important to use the ripest avocados you can get your hands on. If the avocados have brown spots in the meat, avoid those spots when you scoop the meat into the bowl. Place the avocado meat into the bowl of a stand mixer fit with the whisk attachment. Add lemon juice and whisk the avocado on medium speed, until slightly lightened in color ...
Its important to remember that its not just the presence of nutrients in our food that matters, its also our bodys ability to absorb these nutrients. There are certain foods that enable the body to absorb nutrients well. The avocado is one such SuperFood.. Avocado health benefits surpass the nutrients found in avocados alone: Avocados actually improve the bodys ability to absorb nutrients from other foods. In one study, adding about half an avocado (75 grams) to a carrot, lettuce, and spinach salad increased the absorption of the following nutrients in the subjects who ate the salad: alpha-carotene by 8.3 times, beta-carotene by 13.6 times and lutein by 4.3 times compared with the absorption rate of the same salad without avocado.. In a second study, adding a medium avocado (150 grams) to a serving of salsa increased the absorption of lycopene 4.4 times and the absorption of beta-carotene 2.6 times compared with eating the salsa without the avocado.. Both studies concluded that the healthy ...

IRVINE - The Hass Avocado Board (HAB) announced Jan. 8 that a study has revealed that adding one-half of a fresh avocado to a lunch may have helped 26 healthy, overweight people feel more satisfied and reduced their desire to eat following a meal. The avocado study, which was conducted by researchers at Loma Linda University and funded by HAB, was published in Nutrition Journal, a monthly peer-reviewed journal that publishes work in the area of human nutrition. The human clinical study is the second in a series of HAB-funded nutrition studies expected to be released over the coming years as a part of HABs single-minded nutrition marketing and research strategy.. Researchers found that study participants who added half of a fresh Hass avocado to their lunch reported a significantly decreased desire to eat by 40 percent over a three-hour period, and by 28 percent over a five-hour period after the meal, compared to their desire to eat after a standard lunch without avocado. In addition, they ...
In this work we impregnate three Peruvian woods (Calycophy spruceanum Be, Aniba amazonica Meiz and Hura crepitans L) with styrene-polyester resin and methyl methacrylate. The polymerization of the system was promoted by gamma radiation and the experimental optimal condition was obtained with styrene-polyester 1:1 and 15 kGy. The obtained composites show reduced water absorption and better mechanical properties compared to the original wood. The structure of the wood-polymer composites was studied by light microscopy. Water absorption and hardness were also obtained. ...

In three different comparisons of avocados with identical weights but different shapes, the longer, pear-shaped avocados had smaller seeds than the more-rounded ones. For instance, we opened up two six-ounce [170g] Hass avocados, and the seed from the longer one weighed 1 ounce [28g], while the seed from the rounded one weighed 1-1/2 ounces [42g].. The difference of 1/2 ounce [14g] may seem inconsequential, but when you consider that youll need two to four avocados to make guacamole, the difference in yield starts to add up. ...

Yesterday, the girls pulled out their baby pictures, curled up with Dave and me and listened to stories about when they were born. It was such a precious experience - daddy with his girl in his lap and me with mine. And though were all so very excited to welcome Phoebe into our family, I felt a little sad knowing these are our last days as a family of four. Ive enjoyed this phase of our family. Right now, I feel like Ill miss it when Phoebe comes, but my head tells me I wont. When Lucy was on the way, I was certain Id mourn the loss of the just-Julia experience, but honestly, its hard to remember what that was even like, now. Even when I look at pre-Lucy pictures, my first thought is, "Wheres Lucy?" or "Oh, Lucy would have loved that. Too bad she wasnt there for it." Lucy filled an empty piece of our family puzzle - a bright and vibrant one, that somehow causes the big picture to make more sense. Phoebe will do the same. But my heart doesnt know the things my brain does, so right now, ...
