What are biological treatment methods?
Biological treatment methods rely on the natural metabolic processes of bacteria, fungi and higher plants to destroy organic contaminants or convert them to a less toxic or less available form.
How do biological therapies work?
Some biological therapies stimulate or suppress the immune system to help the body fight cancer, infection, and other diseases. Other biological therapies attack specific cancer cells, which may help keep them from growing or kill them.

Other biological therapies attack specific cancer cells, which may help keep them from growing or kill them.
What is a treatment in an experiment?
The treatment is any independent variable manipulated by the experimenters, and its exact form depends on the type of research being performed. In a medical trial, it might be a new drug or therapy. In public policy studies, it could be a new social policy that some receive and not others.

What are biological treatments for depression?
Biological treatments for depression involve antidepressant drugs. Examples are MAOIs, tricyclics and SSRIs. These drugs work by changing the brain's chemistry, especially monoamines like serotonin and noradrenaline. SSRIs like Prozac work by preventing the reuptake of serotonin in the synapse.
What is the most common biological treatment used to treat psychological disorders?
By the 1960s and 1970s lobotomy fell out of favor in the United States. One of the reasons lobotomy fell out of favor was the development in the 1950s and 1960s of new medications for the treatment of psychological disorders; these are now the most widely used forms of biological treatment.
What are the types of biological treatment?
There are two types of biological treatment process; aerobic and anaerobic. Biological wastewater treatment is an extremely cost effective and energy efficient system for the removal of BOD (Biological Oxygen Demand), since only micro-organisms are used.

The group that does not receive the treatment is called the control group.
What are the two types of biological treatment methods?
Biological treatment methods adopted for BW can be generally classified into two major divisions as aerobic and anaerobic treatments. Compared to other treatment methods, biological methods have certain advantages such as (1) treatment technology is traditional and well understood; (2) enhanced efficiency in terms of organic content removal; (3) cost-effective; and (4) environment friendly and safe. A common aerobic method such as activated sludge process is performed by allowing wastewater flow into the aerated tank and agitating the sludge to get a consortium of fungi, algae, bacteria, etc. The vigorous mixing of the biomass enhances oxygen supply, thus facilitating organic matter uptake and microbial reproduction. Trickling filters, rotating biological contactor process, and biotowers have also been employed for the treatment of BW. Their overall treatment efficiency was found to be 40%–50% ( Simante and Hill, 2015 ). Anaerobic treatment composes processes that occur in an environment devoid of air or elemental oxygen. It is characterized by the biological conversion of organic compounds by anaerobic microbes into biogas, which comprises 60%–75% methane and 25%–40% carbon dioxide and traces of other gases such as hydrogen, hydrogen sulfide, and nitrogen. The most significant anaerobic treatment processes that are prevalent in breweries are upflow anaerobic sludge blanket (UASB), fluidized bed reactors, and membrane bioreactors ( Hidalgo and Marroquín, 2019 ).

How to combat pharmaceutical residue?
An effective way to combat the effects of pharmaceutical residue is to isolate the particular elements and then to use bacterial treatment to degrade them or convert them into a benign form. Based on this understanding, bioaugmentation technology involves the use of microorganisms to remove contaminants from any waste product. It can also be incorporated to increase functioning of activated sludge systems by promoting flocculation and settling of the activated sludge.
What is the biological treatment of wood parenchyma?
The biological treatment method is the erosion of wood parenchyma or pit membrane using enzymes, bacteria and fungi, expanding the passageway of wood fluid and improving the wood permeability (Zhang et al., 2011 ).
Is biological treatment effective?
The key to this approach is effective biological treatment. However, it is nearly impossible to have a biological treatment method that is effective for the existing wastewater streams from modern complex chemical manufacturing units. Principal limitations of this conventional method are high volume/detention time, high floor area required, inability to treat complex and unpredictable wastewater, nature of organic load, and the requirement of trained manpower. Some of these limitations are explained below.
How to treat a disease?
There are primarily two ways to treat a disease: 1. Reduce the effect of the disease: Medicines are provided to reduce the pain or bring down the fever. In other words, symptomatical treatment may help to reduce the impact of a disease, but it might not outright cure it.

Cytotoxic therapy involves changing ...
What is nonspecific immunotherapy?
Nonspecific Active immunotherapy. The nonspecific active approach uses agents that set in motion a general immune response, activating a wide range of immune cells. The approach aims at strengthening the overall activity of the immune system instead of selectively arousing those elements most able to fight cancer.
What is the agent used to treat tuberculosis?
The agents used in this method include interferons and interleukins ( IL-2 and IL-12, for example), as well as bacillus (or bacilli) Calmette-Guerin ( BCG ), the organism that causes tuberculosis. The immune response to tuberculosis can cause certain cancers to regress. Researchers have achieved some success by injecting nonspecific agents directly into body cavities where tumors are located. In two studies, for example, the use of BCG led to the complete remission of recurrent bladder tumors in about 70 percent of the patients.
What is tumor cell modulation?
Tumor cell modulation changes the cancer cell's biology so that they become weak and die. Some of the agents used in this approach are called cytotoxins. Perhaps the best-known cytotoxin in this category is tumor necrosis factor ( TNF ), a toxin secreted by activated macrophages to selectively kill tumor cells, principally by interfering with their blood supply.
What is cytotoxic therapy?
Cytotoxic therapy involves changing the cancer cells' biology so that they become weak and die.
