only need a knee replacement if your knee gives you pain, stiffness, instability or LOSS of FUNCTION that affects your daily life and activities.In a healthy knee, the ends of your thigh and shin bones are covered with hard CARTILAGE which allows the bones to move easily against each other. Arthritis damages the hard cartilage so that it BECOMES thin. In places the cartilage may wear away so that your bones rub against each other and become worn.In a knee replacement operation, the worn ends of the bones and any remaining hard cartilage are removed and replaced with metal and plastic parts. The plastic acts like hard cartilage, helping your joint to move freely. The interlocking parts of the artificial joint allow your knee to bend while also making it more stable.You won’t necessarily need a knee replacement if you have arthritis of the knee. But it may be worth considering if your knee is damaged by arthritis and the pain, disability or stiffness are having serious effects on your daily activities.Even then, your healthcare team will always try other measures before suggesting a knee replacement, including drug treatments, physiotherapy and weight loss. If your symptoms are still manageable and your medication is effective then you may prefer to wait.Your orthopaedic surgeon will be able to advise you on the surgical options and the potential pros and cons of having or delaying surgery, taking into account your age, health and LEVEL of activity.Most people who have a knee replacement are over 60. The earlier you have a knee replacement, the greater the chances that you’ll eventually need further surgery. However, there’s evidence that the surgical outcome may be better if you don’t wait until your knee becomes very stiff or deformed.

ry (or ovulation) failure is a term used to describe the scenario where an egg is not released from the ovary. REGULAR periods (monthly cycle) do not necessarily mean that ovulation is occuring and an investigation may be required. Ovulation can be confirmed by ultrasound scans and BLOOD tests. Ovulation usually occurs on day 14 of a 28 day cycle but varies if the cycle is longer or shorter. Mid-cycle pain and clear watery mucus may indicate ovulation.The first and the foremost consequence of failure of ovulation is absence of pregnancy.

erone breakthrough bleeding occurs when the progesterone-to-estrogen ratio is HIGH, such as occurs with progesterone-only contraceptive methods. The endometrium becomes atrophic and ULCERATED because of a lack of estrogen and is prone to FREQUENT, IRREGULAR bleeding.

is a hormone produced by the pancreas. Its function is to allow other cells to transform glucose into energy throughout your body. Without insulin, cells are starved for energy and must seek an ALTERNATE source. This can LEAD to life-threatening complications.Share on PinterestInsulin is a natural hormone produced in the pancreas. When you eat, your pancreas releases insulin to HELP your body make energy out of sugars (glucose). It also helps you STORE energy. Insulin is a vital part of metabolism. Without it, your body would cease to function.

ive reproduction is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structureAdvantagesThe MAIN advantage of vegetative propagation methods is that the new plants CONTAIN the genetic material of only one parent, so they are essentially clones of the parent plant. This can also help to maintain consistent quality and taste in products made from plants or crops.Disadvantages The plants gradually lose their vigour as there is no genetic variation. They are more PRONE to diseases that are specific to the species. This can result in the destruction of an entire crop. SINCE MANY plants are produced, it results in overcrowding and lack of nutrients.

elopment of the transport systems which could accommodate efficient water and carbohydrate transport, was ONE of the most important requirements for the evolution of an efficient land plant. Long-distance transport becomes a serious problem if inefficiencies exist in either system. Growing larger and taller would also not have been possible without the synthesis of lignin. Emergent land plants evolved over a very long time, with the first vascular land plants evolving during the Silurian about 440 MILLION years ago. The first conifers evolved during the Permian (290-250 my); flowering plants during the late Cretaceous (70-65 my) and the first angiosperms during the late Tertiary. The first vascular plants had FAIRLY primitive vascular systems - these were called protosteles fossil members of the Lycopodiales were at the height of their development and dominance during the Devonian and Carboniferous (408- 360 million years ago). The TWO examples that we have chosen to illustrate, have  primitive vascular systems (Lycopodium claviatum and L. saururus  illustrate examples of a fairly 'advanced' protostele, one in which the xylem and phloem has become dissected. We illustrate a fern (Rumohra) and then gymnosperms (Encephalartos, Araucaria,  a MEMBER of the pines). Common amongst these is their vessel-less xylem. We have included a few examples of angiosperms which have eustelic vascular systems in their primary stems,  (Cucurbit which has bicollateral vascular bundles, Nymphaea a hydrophyte with highly reduced xylem, and a Ligustrum species). Finally, we include Zea mays in which the atactostelic condition and dominant influence of the leaf vascular supply is most evident.

ees, Apis mellifera, which perform hygienic behavior, quickly detect, uncap and remove diseased brood from the nest. This behavior, performed by bees 15-20 days old and prior to foraging, is likely mediated by olfactory cues. Because the neuromodulator octopamine (OA) plays a pivotal role in olfactory-based behaviors of honey bees, we examined whether bees bred for hygienic and nonhygienic behavior DIFFERED with regard to their OA expression and physiology. We compared the staining intensity of octopamine-immunoreactive (OA-ir) neurons in the deutocerebral region of the brain, medial to the ANTENNAL lobes, between hygienic and nonhygienic bees (based on genotype and phenotype). We also tested how the olfactory responses of the two lines, based on electroantennograms (EAGs), were affected by oral administration of OA and of epinastine, a highly specific OA antagonist. Our results revealed that bees expressing hygienic behavior (irrespective of genotype) possessed OA-ir neurons that exhibited more intense labeling than same-aged bees not performing the behavior. In bees bred for nonhygienic behavior, OA significantly INCREASED the EAG response to low concentrations of diseased brood odor. Conversely, in bees bred for hygienic behavior, epinastine significantly reduced the magnitude of the EAG response, a reduction not observed in nonhygienic bees. Our results provide two lines of evidence that OA has the potential to facilitate the detection and response of honey bees to diseased brood. We discuss the contributions of OA for BEHAVIORAL shaping and its ABILITY to bias the nervous system to express one form of behavior over another.
