Nanotechnology is an emerging field of science deals with materials in nanoscaled size (0.1 – 100nm).
Nanomaterials have superior properties than bulk substances : Mechanical strength, thermal stability, catalytic activity, electrical conductivity, magnetic and optical properties.
Metal NPs: ZnO, TiO2 , SiO2.
ZnO NPs exhibits antimicrobial properties which depends upon their size and shape.
“Biogenic synthesis” of nanoparticles makes use of environmental friendly, Non-toxic and safe reagents.

Production of tetracyclin and cephalosporinSamsuDeen12
Tetracyclin and cephalosporins are one of the major used antibiotics commonly all around the world. They are used to treat against microorganisms as a bactericidal, these eliminates those organisms in the host through various mechanism. These antibiotics are produced in a large scale using a bioreactors in many countries.

Sulphonamides and their combination with trimethoprim - by Dr.Jibachha SahDr. Jibachha Sah
Sulphonamides and their combination with trimethoprim is lecturer notes on Veterinary Pharmacology & Toxicology(Chemotherapy) for B.V.Sc & A.H students of veterinary college.
INTRODUCTION
Sulfonamides were the first effective, synthetic antibacterial agents to be used systemically in man.
They were introduced by Domagk in 1935 and in the next few years several of them were synthesized and widely used. Currently their role in therapeutics is limited because of their toxicity, development of resistance availability of safer drugs.
CLASSIFICATION
Short acting: Sulfisoxazole, Sulfadiazine
Intermediate acting: Sulfamethoxazole
Long-acting: Sulfamethoxypyridazine, sulfadoxine
Poorly absorbed: Sulfasalazine
Topical: Sulfacetamide, mefedine
Silver sulfadiazine.
ANTIBACTERIAL SPECTRUM
It is wide spectrum antibiotic.
It inhibits many gram positive and some gram negative bacteria including streptococci, H. influenza, Norcardia, E. coli, proteus, V. cholerae, some stains of staphylococci, gonococci, memingococci and pneumococci.
They are also effective against Chlamydia, plasmodium falciparum and toxoplasma gondii.
MECHANISM OF ACTION
PABA (Para-aminobenzoic acid)
Folic acid synthesis
DIHYDROFOLIC ACID
Bacteria synthesize their own folic acid from PABA with the help of the enzyme folic acid synthetase. Sulfonamides are structurally similar to PABA and competitively inhibiting the enzymes folic acid synthetase.
They inhibit the enzyme folic acid synthase so folic acid is not synthesized (which is essential bacterial growth).
PHARMACOKINETICS
Sulfonamides are well absorbed, extensively bound to plasma proteins and are well distributed to all tissues.
They are metabolized in the liver and excreted in urine.
They can cross placental barriers.
COMMON USES
SYSTEMIC USES : sulfamethoxazole is used in combination with cotrimoxazolein many bacterial infections.
It is the drug of choice in pneumocystitis in AIDS patient.
Treatment of nocardiosis, toxoplasmosis, ulcerative colitis and rheumatoid arthritis.
TOPICAL USES: ocular sulfacetamide sodium is used in trachoma/inclusion conjuctivitis.
Topical silver sulfadiazine is used for preventing infection on burn surfaces.
Mefinide is active in the presence of pus and against pseudomonas, clostridia which are not inhibited by topical sulfonamides.
USES
Because of the development of resistance and availability of better antimicrobials, which are more effective and less toxic, these are not commonly used now except in a few cases:
UTI
NOCARDIOSIS
TOXOPLASMOSIS
TRACHOMA AND INCLUSION CONJUCTIVITIS
MALARIA
TOPICAL
ULCERATIVE COLLITIS
Contraindication & Precautions: Children younger than 2yrs, Pregnant and breast feeding mother, Renal and hepatic diseases, Hypersensitivity to sulphonamides drug.
Adverse effect: Fever, Rash, Nausea/vomiting, Aplastic Anemia.
DRUG INTERACTIONS
Sulphonamides can increasing the blood thinning effect of warfarin, possibly leading to abnormal bleeding.
Increases blood level of potassium may occur when Sulfamethoxazole trimethoprim is combined with ACE inhibitors.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202
