1) Yellow: This is often used for isolation wastes, such as those from
patients with a communicable disease or from the isolation ward. It may also be
used for trace chemotherapy waste.
2) Black: Typically used for non-infectious waste that is not recyclable, such
as general waste from hospital areas not directly involved in patient care.
3) Green: This is commonly used for anatomical waste, which includes human
tissues, organs, body parts, and animal carcasses used in research or treatment.
4) Red: As mentioned, is used for infectious or biohazardous waste that poses a
risk of infection or disease transmission.

Pharmacology
In humans, isosorbide mononitrate is not subject to first pass metabolism in the liver.
This reduces the intra- and interindividual variations in plasma evels and leads to predictable and reproducible clinical effects.

Fexofenadine is the active metabolite of terfenadine that does not block delayed rectifier K channels in the heart and does not prolong QTc interval. It is free of arrhythmogenic potential, does not cross the blood-brain barrier, and does not produce sedation. It has a plasma half-life of 11-16 hrs and duration of action 24 hrs.

General Medicine
In restrictive lung disease, the FEV1/FVC ratio and compliance of the lung are
decreasing.
Restrictive lung diseases, such as pulmonary fibrosis or severe asthma, are
characterized by a decrease in the lung's ability to expand due to factors like
stiffening of the lung tissue or a reduction in the volume of the thoracic
cavity. As a result, the forced expiratory volume in one second (FEV1) is
reduced in relation to the forced vital capacity (FVC), leading to a decreased
FEV1/FVC ratio. Additionally, the compliance of the lung, which is a measure of
the lung's ability to expand and contract, is also decreased in these conditions
because the lung tissue becomes less elastic.

State PSC PYQEmotional stress is a significant contributing factor to necrotising periodontal diseases (NPD) as it can suppress the immune system, making an individual more susceptible to bacterial infections and impairing the body's ability to fight off the disease. Other factors like poor oral hygiene and lack of regular dental care are also involved, but stress is a key predisposing factor.

General Microbiologythe live oral vaccine for typhoid fever is Typhoralx, which is a Gal E mutant of S. typhi. The mechanism of action involves the attenuated bacteria colonizing the intestinal mucosa and inducing an immune response that protects against subsequent infection with the pathogenic strain.
