Computer problems those can be solved at home

1. Computer shutdown safely on previous days don't showing display now. Particularly during damp season it is a common problem. Switch off the power button. Open the side cover of your CPU. It is easy. Remove two screws on the back of the CPU on the left side. Then push the side cover gently and remove it. In side the CPU find the slots of RAM. Push the white clips on the two ends apart of each RAM gently. Remove the RAM from its slot and clean the metallic (brass ) border with a brash or piece of cloth. And also clean the slot by a dry bash several times.Then place the RAM gently on the slot. Restart the CPU. CPU should be opened at least once a month to clean the dust regularly with blower or a soft paint brash. 2. Old keyboard may create problem: During starting, computer sounds with a short beep. During starting if computer sounds with a long beep or two or more short beep that is other than a short beep should be considered as something abnormality in the hardware. And your computer will work properly in this situation. The most provable cause is the old ( even new sometimes) keyboard, due to many causes particularly logging small insects or food particles under the keys causing abnormal command. How will you confirm it? Power off the computer, remove the keyboard and restart the CPU. If it works correctly replace the keyboard or one can also clean the old keyboard cautiously and then reuse it (better don't use it). 3. In a used computer widows or other softwares not working properly: In a used computer (particularly older than one year) when newly installed windows or any other softwares do not works properly , it may be due old CD or DVD ROM drive which fails to read any application file(s) of the windows or the softwares installed recently. For the windows setup use new CD or DVD ROM drive and for other softwares one can alternatively ( escape buying a new CD drive) use the softwares by coping it first in a drive of the hard disk and reinstalled from the hard disk.

Resurgent of Vector borne Diseases- In context to Bangladesh :Some Suggestions

Different mosquitoes: anopheles, Culex and Ades -transmit malaria, filaria/Japanies B Encephalitis,and dengue/yellow fever/chikangunya respectively.

The effects of globalization in exacerbating the risk of spreading infectious diseases are mediated not only through the movement of people but also by the increased mobility of disease vectors, livestock and other animals that may host zoonoses, as well as the greater propensity for food-borne disease in consequence of increasing legal and illegal trade.

Infected mosquitoes can be trnsported via train, ship, bus directly in luggages or bags.

In the 120 years since arthropods were shown to transmit human disease, hundreds of viruses, bacteria, protozoa, and helminthes have been found to require a hematophagous (blood-sucking) arthropod for transmission between vertebrate hosts). Historically, malaria, dengue, yellow fever, plague, filariasis, louse-borne typhus, trypanosomiasis, leishmaniasis, and other vector-borne diseases were responsible for more human disease and death in the 17th through the early 20th centuries than all other causes combined.

In context to Bangladesh, India can be major source of those new types of diseases like dengue. In India, dengue has been epidemic for several years. Although dengue fever was documented in Bangladesh from the mid-1960s to the mid-1990s, but an outbreak of dengue haemorrhagic fever has not been previously reported.But in 2000, through mid ­November 5,575 hospitalized dengue cases were reported to the Ministry of Health in Bangladesh, with a case-fatality rate of 1.61 %.

Ades mosquito, the vector of this disease, can not fly more than 100 meters from its residence. So, there is no way to move this vector from air port to populating area of Dhaka, where dengue outbreak started first in Bangladesh. Moreover, the air way communications from Bangladesh to India have been established many years before liberation but there was no dengue outbreak during this period. So, there is very little chance of transmitting the disease by this route. Moreover, under the WHO International Health Regulation (IHR), all international airports and seaports are kept free from all types of mosquitoes for a distance of 400 meters around the perimeter of the ports.8 But it is possible that, the infected mosquito can travel via bus or train under their seats, in between luggage and transmit the disease to other populating area nearby the stoppage. The time of emergence of dengue outbreak in Bangladesh that occurred first in Dhaka coincides with period after the introduction of bus communication between Dhaka and Kolkata. So it will be logical to claim that the infected vectors can easily migrate to Dhaka via bus from India. Now, the recent introduction of railway communication can exacerbate the condition or import of new diseases agents like Japanese B encephalitis, chikangunya which are known to prevalent in many areas of India. So, it should be an urgent matter to prevent such migration of vectors through vehicles like bus or train.

The measures those can be taken to limit vectors migration could be as follows:

1) Before starting, the train or bus should make free from any vectors by using effective insecticides before the passengers take their seats.

2) The international train or bus should not be used for domestic purposes.

3) The stoppages for train or bus in both countries should be sufficiently away from localities and the area should be carefully monitored for vectors.

4) Traveler's quarantine should be strictly maintained. Our government should be aware of the factor of migration of infected vectors urgently. If it is ignored, it will be not so late when even a lay man will bother for uncommon diseases like Japanese B encephalitis, chikangunya or other uncommon vector borne diseases as like as dengue today.

The recent outbreake of swaine flu in Bangladesh is a great concern which was first introduced in Dhaka by a infected passenger came from USA through air-port. I think it was not so difficult to prevent entry of such pandemic disease in our country through airport if sufficient measures were taken to quarantine the suspected patient coming from outside of the country.

Health care: Food & Antioxidant- How does it help us

It is now a common saying that antioxidant is beneficial for health. But what is antioxidant and how does it help us? What are the sources of antioxidants? Before that we should know about oxidation better term autoxidation. In our daily life a continuous process called metabolism is going on in our body, by which we are getting energy from our foods. During this process of metabolism some chemical or elements ( called free radicals -highly reactive atoms or molecular species due to unpaired electrons) are produced in our body which cause some harm full effects on the cells of our body by a process called oxidation. Autoxidation is any oxidation that occurs in open air or in presence of oxygen and/or UV radiation. The process of autoxidation has enormous economic impact, since all foods, plastics, gasoline, oils, rubber, and other materials that must be exposed to air undergo continuous destructive reactions of this type. All good plastics and rubber and most processed foods should contain certain chemical (called antioxidant) to protect them against the attack of oxygen. The oxidation of food products involves the addition of an oxygen atom to or the removal of a hydrogen atom from the different chemical molecules found in food. Two principal types of oxidation that contribute to food deterioration are autoxidation of unsaturated fatty acids (i.e., those containing one or more double bonds between the carbon atoms of the hydrocarbon chain) and enzyme-catalyzed oxidation. The autoxidation of unsaturated fatty acids forms free radicals producing compounds that cause the off-flavours and off-odours characteristic of oxidative rancidity. Antioxidants that react with the free radicals (called free radical scavengers) can slow the rate of autoxidation. These antioxidants include the naturally occurring tocopherols (vitamin E derivatives) and the synthetic compounds butylated hydroxyanisole (BHA), butylated hydroxytoluene (BHT), and tertiary butylhydroquinone (TBHQ). Specific enzymes may also carry out the oxidation of many food molecules. The products of these oxidation reactions may lead to quality changes in the food. For example, enzymes called phenolases catalyze the oxidation of certain molecules (e.g., the amino acid tyrosine) when fruits and vegetables, such as apples, bananas, and potatoes, are cut or bruised become brown in colour. The product of these oxidation reactions, collectively known as enzymatic browning, is a dark pigment called melanin. Antioxidants that inhibit these browning of fruits are reducing substances such as ascorbic acid (vitamin C), and agents that inactivate the enzymes, such as citric acid and sulfites. In human, free radical injury can be minimised by Antioxidants, which are substances that may protect cells from the damage caused by unstable molecules known as free radicals. Free radical damage may lead to cancer. Antioxidants interact with and stabilize free radicals and may prevent some of the damage free radicals might otherwise cause. Examples of antioxidants include beta-carotene, lycopene, vitamins C, E, and A, and other substances.

Which foods are rich in antioxidants? Antioxidants are abundant in fruits and vegetables, as well as in other foods including nuts, grains, and some meats, poultry, and fish. The list below describes food sources of common antioxidants.

Beta-carotene is found in many foods that are orange in color, including sweet potatoes, carrots, cantaloupe, squash, apricots, pumpkin, and mangoes. Some green, leafy vegetables, including collard greens, spinach, and kale, are also rich in beta-carotene.

Lutein, best known for its association with healthy eyes, is abundant in green, leafy vegetables such as collard greens, spinach, and kale. Lycopene is a polymer of beta carotene and a potent antioxidant found in tomatoes, watermelon, guava ( red), papaya, apricots, pink grapefruit, pomegranate, blood oranges, and other foods.( not in strawberry or red berries). Lycopene is heat stable and is available in processed fruits containing natural lycopene e.g tomatoes sauch ( one tomato contain 3.5 mg lycopene but one cup of sauch contain 28 mg lycopene)

Vitamin A is found in three main forms: retinol (Vitamin A1), 3,4-didehydroretinol (Vitamin A2), and 3-hydroxy-retinol (Vitamin A3). Foods rich in vitamin A include liver, sweet potatoes, carrots, milk, egg yolks, and mozzarella cheese. Vitamin C is also called ascorbic acid, and can be found in high abundance in many fruits and vegetables and is also found in cereals, beef, poultry, and fish. Vitamin E, also known as alpha-tocopherol, is found in almonds, in many oils including wheat germ, safflower, corn, and soybean oils, and is also found in mangoes, nuts, broccoli, and other foods.

Health care: Allergy-"CONTACT DERMATITIS"

In previous blog I tried to discuss on allergy which in medical term called Type I allergy that is mediated by a chemical, immunoglobulin (IgE) produced plasma cells in our body by the help of TH2 cells. But there are other types of allergy also. Most important of them is type IV which can be prevented by the people themselves. The disease caused by this type of allergy is mostly called 'contact dermatitis'. The very name suggests the cause. It is manifested by chronic eczematous lesion with intense itching in skin of hands or foots or any site of body that remain contact with abnoxious materials for prolong period. Pic: Contact dermatitis with rubber It is usually due to contact of our skin to many substance like cosmetics, many metals commonly nickel in watch belt or eye glass frame, plastics, rubber, different dyes specially hair dye, dye used in cloths, spray as aerosol etc. Even some sorts of light can also be harm full specially for eye causing chronic watering or itching which decrease upon exposure to day light after coming from the indoor. Here is a case report of watering from eyes of a boy of 12 years. The boy was suffering from watering and itching of both eyes for the last 2 years. Ophthalmologist prescribed him symptomatic treatment with local steroids and antihistamines but problem persisted when drugs discontinued. The family was known to me from the childhood of the boy when there was no ocular problem. During taking history I observed that the onset of the disease coincide with their changing of residence in their new house 2 years before and the patient admitted that his symptoms aggravated when he stayed at home and decreased when he became out his house. So, I became assure that the allergic agent was in side his house. I advised him to change his bed to another room when he felt better than when he was in his old room and advised him to shift his used materials from his old room to new place gradually in 2 to 3 days. Ultimately the culprit was identified that it was his table cloth which was a plastic oil cloth of bright yellowish green colour. As soon as it was removed his room he got cured from the symptoms. It is important that, any affected person who acquired the disease for the last few weeks or months, should think first of any articles including new bed seat, pillow cover or other dress or any household objects those have being used for last few months or period which coincide with the onset of his or her disease.

Pic: Plastic contact dermatitis watch belt It should also be noted that, contact dermatitis is acquired several days to few weeks after contact with the offending materials. So it is clear, that living in a artificial environment using mostly artificial materials favours allergy like contact dermatitis. Hair dyes are most dangerous and recently most (about 22) ingredients been banned by European union as they have been found to be related with bladder cancer. Body aerosols have been found to be related with breast cancer. Light colour is good and best colour is white. It is cool for all.

Health care: Allergy- how can we prevent it

google10f0934a5965041e.html Allergy is called in medical term, hypersensitivity. We are exposed day to day to many substances like chemicals in the form of cosmetic, household paints, essences or colour materials in our foods or drinks, artificial leather in our shoes, plastic materials used in different objects including toys, plastic or metal belt in watch and so many foreign ( not present in our body)materials which are needed in daily life and different organisms including bacteria, viruses, fungus or parasites. Allergy most commonly affect the nose, eyes, skin, and lungs. These disorders include atopic dermatitis, contact dermatitis, urticaria Different people show allergy to different substances. One person reacts to a particular substance whether other person do not show any reaction to the same substance. Few people in a particular family may show allergy, these are called atopic person.

Etiology :

Genetic and environmental are important factors.

Genetic factors may be involved, as suggested by familial inheritance of disease.

Environmental factors are thought to be very important. It is proved that allergy is more common in developed countries than developing countries and similarly more common in urban area than rural area. In medical science it is proved that, there are cells ( called TH2 ) in our blood responsible for development a situation during childhood that will develop allergy in later life. Early childhood exposure to bacterial and viral infections and endotoxins (eg, lipopolysaccharide) can control these cells in our blood involved in allergy by suppressing them. But trends in developed countries toward smaller families with fewer children, cleaner indoor environments, and early use of vaccinations and antibiotics may deprive children of exposure to infectious agents that fail to suppress the cells related with allergy. Such trends may explain the increased prevalence of some allergic disorders in developed countries or in urban areas of developing countries. Other factors thought to contribute to allergy development include chronic allergen exposure and sensitization, diet, and environmental pollutants. So, growing up of children in natural environment rather than a more restricted way will prevent allergy significantly.

Prevention of Filariasis ( গোদ রোগ )

Filariasis is a very common disease in northern region of Bangladesh and many other countries including African countries. The name of the organism is Wuchereria bancrofti and Brugia malayi. ( Pic: microfilaria of Wuchereria bancrofti in blood) Most of the species of mosquito can transmit the disease by carrying larva( called microfilaria) from infected person during their blood meal. Only the female mosquito can transmit the disease. After infection a man harbour the filarial worm for about five years in their lymphatic tissue. During this period this person could be a source of infection. We can prevent this transmission by giving albendazole 400 and 300mg diethycarbamazine (adult dose) yearly for five years to both infected and uninfected persons in an endemic area. Chronic filariasis can cause elephantiasis-swelling of legs, hands, scotum, labia or breast. Swelling of breast can be cofused with breast tumor. So the history of residence is very important in this instance. In infected person, a small larva, called microfilaria can be found in blood, chylous urine( milky white), hydrocele fluid and other body fluids. See two video clips of microfilaria in blood and urine.

Common water Filters and Viral Hepatitis

Water borne viral hepatitis (A, E) is a common problem in Dhaka and other areas of Bangladesh and also in many other countries. There are many causes for the present situation. It is partly due to the lack of knowledge of water purification. Boiling is best among the all methods but it needs a setup of heating appliance. So, many people think that water filters, those are used in Bangladesh are safe. Actually water filters without UV or heating can't prevent viral infection because size of virus is very very small and its access can not be prvented by the common filters. Without UV or heating some good types of filters can prevent parasitic disease and some times bacterial infections like salmonella, vibrio or shigella which are responsible for enteric fever or gastroentritis respectively. Moreover, one can easily observe that there is no BSTI logo for quality of these filters in Bangladesh. So these filters are not helping rather misleading the people. General people using the filtered water with a good faith and are suffering. Boiling is very good but if not availble then use of chlorine tablet or liquid is more helpfull then filter.

Health care: How will you make Vegetables safe from Insecticide

It is a common practice among the vegetable growers that insecticides are sprayed in the vegetables just before marketing to keep their products fresh for longer time. But it is not safe for health nor is permissible. At least it should be applied a week before marketing the vegetables. The insecticide used in such a way is definitely health hazardous. But it is not preventable at least in the context of Bangladesh situation. So, it is duty of the consumers not the government to create a way to use safe vegetables. But how? It is easy. Before cutting the vegetables make a solution of sodi-bi-carb (sodium bicarbonate) by mixing one table spoon full of soda in two liters of and water the vegetables in the bucket of solution and keep for at least five minutes and wash in it. Then remove the vegetables from the solution and wash in plain water and now ready for cutting or consuming.

No paste for Oral Health

We most of the people use dental paste to clean our mouth regularly. Did you think that it is always helpfull? It is not. I am a medical microbiologist. I want to explain with my experience. Cleaning of mouth means to clean the food partcles from our mouth those remained every after meal or eating in the space of teeth or gum. So it is unnessesary to use any chemical in our mouth, only a branch of tree is enough to serve the purpose. If one use this type of branch of tree four or five times a day or every after eating it will keep one's mouth normal without any hazourd. Rather any chemical which may contain antiseptic or mouthwash should do harm to the normal flora of our mouth, or these chemicals should be absobed from mouth and can cause remote side effects on our many vital tissue like kidney or liver. In this way the normal flora will develope resistance to many antiseptic and later on creat problem in the treatment on many infections. More over loss of money is also a factor. If you observe to the people who are Imams or khadems of a masjid that they never use any paste and they rarely go to the dentist. People of rural area use paste less than urban area and most of the dental patients come from urban area.
