Benefits of Pre-implantation Genetic Screening

We are observing tremendous advancement in the field of medical genetics. The application of genetic technologies to the arena of reproductive medicine has steered in a new epoch of treatment. Pre-implantation Genetic diagnosis is considered as an alternative to prenatal diagnosis.  Pre-implantation Genetic Screening is a type of genetic test design to enhance the success of IVF. Preimplantation genetic screening, abbreviated as PGS is the process of determining the presence of aneuploidy in a developing embryo. Preimplantation genetic screening is conducted on embryos produced through IVF. In PGS, a biopsy is taken either from the polar body of a mature oocyte or from cells taken from developing embryos and genetically analyzing the composition of these cells.

This screening provides valuable information about genetic health of embryo which help embryologist to select the best embryo for transfer and improve chance of a successful pregnancy.

Pre-implantation Genetic Screening is best suited for women undergoing IVF. All females are in danger zone of producing chromosomally abnormal embryos. With age, the potential for chromosomally abnormal embryos considerably increases. Therefore, Pre-implantation Genetic Screening helps in positive end of pregnancy. PGS gives information for several disorders such as Down syndrome or Turner syndrome which develop due to an abnormal number of chromosomes in certain positions.

Pre-implantation Genetic Screening is mainly referred to older females who are more likely to have eggs with the wrong number of chromosomes. Abnormal chromosomes are major cause for older women facing difficulties in conceiving and there are more chances of miscarriage or a baby with Down’s syndrome.

 Major advantages of performing Pre-implantation Genetic Screening are higher chance of pregnancy, lessening risk of miscarriage, confidence in transferring a single embryo, evading health risks related with twin or triplet pregnancies and reduced number of IVF cycles required to achieve pregnancy.

Some genetic experts argued that PGS sometimes is an inaccurate diagnostic procedure for embryos. Though it is outstanding tool for reproductive endocrinologists to increase IVF efficiency, but Preimplantation genetic screening is not faultless in its diagnostic precision. This chance of misdiagnosis results from both biological and technical limitation.

In final comment, it can be realized that PGS is a procedure for testing whether embryos have some problems with their chromosomes or not.

Agricultural Drones are helpful in crop production

Farmers often get puzzled and worried about their farm when they have problem with crop growth. Sometimes plants are wilting and growing more slowly. Farmers cannot instantly diagnose what causes such sluggish growth. To resolve these issues, drones are developed. Drones that fly are also called unmanned aerial vehicles.

Agricultural drones are the outcome of emerging technology and revolution in agriculture industry. These drones are applied to agri-business in order to augment crop production and observe crop growth. Today agriculturalists have great options of using drone with advanced sensors and digital imaging capabilities to help them gather good picture of their fields. This valuable information congregated from such equipment is useful to enhance crop yields and farm productivity.

To operate drone, farmers enters a flight path for the drone using smart phone. They program in the area of field where the drone must take images and videos. The drone flies on its own but the farmer watches as it crisscross the field. After about 20 minutes, drone returns to the farmer and lands. Then farmer has to download data from drone to his laptop and evaluate the images captured by drone camera. He can see evidences of pests on the leaves, notices dry patches in the soil where the plants lack water. With such relevant information, farmers can now manage their crops.

Drone technology is highly beneficial for the agriculture sector as it provides a high-technology remodelling, with planning and strategy based on real-time data collecting and processing. Aerial and ground-based drones can be used for soil and field analysis, planting, crop spraying, crop monitoring, irrigation and health analysis.

Best part of these smart farming drones is that a drone can fly under any weather condition. Drones are water resistant, but there may be poor image quality if pictures are taken during drizzling weather. Important fact about drones is that it can fly around 50 - 100m high. Drones can capture farm pictures with a resolution down to a few cm per pixel. A drone can get higher quality and higher precision of images in real time as they can fly below the clouds. Basically raw data gathered by drones is translated into valuable information for farmers. These images provide plant counting such as plant size, plot statistics, stand number, compromised plots, planter skips, plant height, vegetation indices, water needs.

Most suitable drones for farming monitoring are fixed wing and multi rotor drone. Fixed wing drones have capacity to monitor long range of area. They are also crash tolerant.

Multi rotor drone are faster to set up in the field and can take off and land vertically.

In India, drone manufacturing market is growing and many industries are jumping to this business. For agricultural spraying multicopters, the Department of Agriculture Machines and Technology of the University of Agricultural Sciences had developed a multicopter for spraying pesticides on high and tall crops. 

Drones guarantee a permanent monitoring of the yield in the field from planting to harvest. Drone can help agriculturalists to appraise issues which affect production and sustainability. Drone technology offers agriculturists with a lucrative method of infrastructure planning.

In short, JavaScript is a full-grown dynamic programming language. When applied to an HTML document, it can provide dynamic interactivity on websites.

One second far from death

We frequently travel for different purposes in life such as for work, medical reasons and leisure via train, road or by air. In today’s high paced life, we are susceptible to danger and there is a need to know the escape strategies to shield our families while travelling through any mode. 

The main intent of this write up is to generate awareness regarding human error in aviation hazards. It is considered that flying is the safest mode of transport as there is aviation technical team to look after and crew members take care of passengers. Still we hear dreadful aviation mishaps.

 It is a big question, why airplane crash and innocent passengers are killed.

Human errors are highlighted when any airplane crash news normally flashed. It is well evident that humans make mistakes therefore human error has been implicated in several occupational accidents. It is a general consensus of investigators, aviation intellectuals that most aviation accidents do not happen in remoteness. Instead, these are the consequence of series of events often ending with the perilous acts of aircrew. Errors signify the mental or physical actions of aviation members that fail to attain their intended outcome. When we talk about these errors in aviation, the most common error is decision errors which represent conscious, goal-intended behavior that proceeds as designed. Yet, the plan proves inadequate or inappropriate for the situation. These denotes to honest mistakes and such unsafe acts usually manifest as poorly executed procedures, unsuitable choices, or simply the misunderstanding or misuse of relevant information.

Another form of error in aviation disaster is skill-based errors which occurs with little or no conscious thought. Basic flight skills happen without momentous conscious thought. Consequently, these skill-based actions are particularly susceptible to failures of attention and/or memory. Actually, attention failures have been associated with numerous skill-based errors like the breakdown in visual scan patterns, inadvertent activation of controls, and the misordering of steps in procedures.

Lastly, there is perceptual errors which receives less attention in airplane crash. Perceptual errors happens when sensory input is ruined or “unusual,” especially when flying at night, in rough weather, or in other visually disadvantaged conditions. Pilots act on inadequate information and run the risk of miscalculating distances, altitude, and decent rates, along with responding erroneously to several visual/vestibular illusions. Basically, it is the pilot’s flawed response to the illusion or bewilderment.

For example, “Tenerife Airport Disaster”, the most heartbreaking incident occurred in March 1977. It was the vilest aviation disaster happened on Tenerife, with neither plane actually in the air. A total of 583 passengers in two different planes lost their lives unreasonably because of a combination of poor visibility due to fog and disordered communication between air traffic control and the two pilots involved, resulting in loss of situational cognizance.

Another dreadful aviation accident was “Air France Flight 447” in May 2009.  Air France flight 447 took off from Rio de Janeiro in Brazil bound for Paris with 228 passengers on board. Investigators found that main cause of the accident was the freezing of the pitot tubes which caused the autopilot to disconnect. This resulted in the aircraft switching from normal law to alternate law with no stall protection on control inputs. The poor diagnosis of the situation led to the pilot demanding full nose up.

A collision took place when one of the planes mistakenly thought they had been cleared for takeoff while the other was still on the runway. The pilot and co-pilot of the KLM flight only realized too late when they caught site of the PanAm flight through the fog.

To end this important discussion, we can sense that human factors have pivotal role in wellbeing in the aviation sector. Because single or hairline error of aircrew due to misapprehension or poor procedures can throw the passengers to death mouth and result in calamitous events. The state of passengers travelling from air is just One second far from death if things are not perfect.

Reasons for erupting sinus problems

Sinuses is a health problem around the globe. Health reports signify that this problem troubles millions of people in the United States. People who have allergies, asthma, structural blockages in the nose or sinuses, or people with weak immune systems are in risk zone of sinus.

The sinuses are air-filled cavities. There are eight sinus cavities in total. They are paired, with one of each in the left and right side of the face.

-       Two sinus cavities are in forehead.

-       Two are behind each cheekbone.

-       Two sinus cavities are within the bones between your eyes.

-       Two are behind each eye.

Sinusitis is a swelling of the sinuses. It is mainly caused by bacterial (germ) infection. Sometimes, problem emerges due to viruses and fungi (molds). Sinus ailment breaks the normal flow of mucus from the sinuses to the back of the throat. The tiny hair-like "sweepers" become blocked when infections or allergies cause tiny nasal tissues to swell. The swelling traps mucus in the sinuses.

People who have weak immune systems are prone to develop bacterial or fungal sinusitis. Acute sinus disease lasts three to eight weeks. If people suffer from sinus disease more than eight weeks, it becomes chronic. If there is an infection of the sinus cavity near to the brain, then it can be dangerous when left untreated. In exceptional cases, it can spread to the brain.

Sometimes, sinus problems are the outcome of a deviated septum. The front portion of the nasal passages has a firm but bendable structure of cartilage separating the two nostrils. The ideal septum should be placed right down the midline so that both nostrils take in and release air evenly. When the septum is too far from the midline, it is called a deviated septum and can cause sinus problems.

Another cause of developing sinus problem in people is Food allergies. Gluten intolerance and milk allergy trigger sinus disease. Environmental Allergies also lead to nasal problem. Dust, pollen, mold, and pet dander can keep the body’s defence mechanisms in hyper-drive throughout the day, leading to chronic and lifelong sinus complications. Additionally, some chemicals such as cleaning products, air fresheners, and cosmetics can cause post-nasal drip and other sinus problems.

Sinusitis symptoms:

Common symptoms of sinusitis include:

-       Postnasal drip

-       Discoloured nasal discharge (greenish in colour)

-       Nasal stuffiness or congestion

-       Tenderness of the face

-       Frontal headaches

-       Pain in the teeth

-       Coughing

-       Fever

-       Fatigue

-       Bad breath

-       Eye pain

Sinusitis diagnosis:

People, who feel they are suffering from sinus disease, must visit to doctor for proper diagnosis. In most cases, sinus disease can be treated. Diagnosis depends on symptoms.

If sinus disease lasts longer than eight weeks, a sinus CT scan may help doctor to diagnose the problem.

Sinus disease Treatment:

Doctors prescribe antibiotics for bacterial sinusitis. Antibiotics are usually taken from 3 to 28 days, depending on the type of antibiotic. Antibiotics help eliminate sinus disease by attacking the bacteria that cause it. Topical nasal decongestants can be helpful if used for no more than three to four days. If drug therapies do not work, surgery may be recommended as a last option. It is generally performed by an otolaryngologist.

Natural remedy for Chronic Sinus Problems:

Traditional methods to treat chronic sinus problems include antihistamines, decongestants, and expectorants. These may work in the short term to address symptoms but they do nothing to address the original cause. Patients with chronic sinus problems must explore the allergies of foods and environmental causes that trigger such medical condition.

In general, people grip under sinus must flush their nasal passage, take steam, spice it up and apply warm compressor.

It is well documented in health reports that Sinus infections strike about millions of people around the world. Sinusitis is a common health problem in which the lining of the sinuses becomes swollen. It is usually caused by a viral infection and often recovers within two or three weeks. It is not a worry for people if their symptoms are mild and recovered with time but if symptoms are severe or getting worse, then person must get advice from general physicians to know the causes of developing this medical condition.
