His wife, Maureen, is a clinical psychologist and psychoanalyst. [3] [4] They have two sons.[ citation needed ]
Landry directed the Doris Duke Clinical Research Fellowship Program's Columbia site and co-directed the Advanced Pathophysiology course for 4th-year medical students at the Columbia College of Physicians and Surgeons, both for over a decade. [5] Landry was a member of the President's Council on Bioethics and is co-chair of the Witherspoon Council for Ethics and the Integrity of Science. [1] [6] He is a founder of Tonix Pharmaceuticals (NASDAQ: TNXP), [7] a member of the Board of Directors of Sensient Technologies, and chair of the scientific advisory board of Applied Therapeutics, Inc., which was founded based on his patents and now trades on NASDAQ. [8] [9] He is co-founder of Tegrigen Therapeutics, a biotech start-up focused on integrin targets.
Landry was elected to membership of the American Society for Clinical Investigation and the Association of American Physicians. [10] [11] He is listed in Who's Who in the World and in 2015 was inducted at the Smithsonian as an elected Fellow of the National Academy of Inventors. [12] [13] Landry received the Presidential Citizens Medal, the nation's second-highest civilian honor, from President George W. Bush at the Oval Office in 2008 "for diverse and pioneering research and his efforts to improve the well-being of his fellow man." [14]
Landry has focused on novel approaches to intractable health problems, combining medicine and organic chemistry. His work on cocaine addiction led to the discovery of an artificial enzyme to degrade cocaine. His report on the enzyme, published in Science, was chosen by the American Chemical Society as one of the 25 most important chemistry papers in the world for 1993. [15] [16] An agent (Cocaine esterase) he co-developed to treat cocaine overdose has entered clinical trials from Tonix Pharmaceuticals. [17] [18] [19] He founded the Columbia Organic Chemistry Collaborative Center and it is through this Center that he conducts his current work on drug discovery. [20]
Landry discovered a new hormone deficiency syndrome: vasopressin deficiency in vasodilatory shock. In pioneering the use of vasopressin to treat septic shock and vasodilatory shock after cardiopulmonary bypass, he changed clinical practice for these life-threatening conditions. He also founded ICU nephrology at Columbia, introducing continuous renal replacement therapy to treat renal failure in patients with shock. [21]
Landry developed an alternative method for the production of human embryonic stem cells that relies on harvesting live, normal cells from embryos that—by objective, peer-reviewed criteria—have died of natural causes. Cells harvested from dead embryos would be covered under the established ethics governing transplantation of essential organs from deceased donors. [22]
Nephrology is a specialty for both adult internal medicine and pediatric medicine that concerns the study of the kidneys, specifically normal kidney function and kidney disease, the preservation of kidney health, and the treatment of kidney disease, from diet and medication to renal replacement therapy. The word "renal" is an adjective meaning "relating to the kidneys", and its roots are French or late Latin. Whereas according to some opinions, "renal" and "nephro" should be replaced with "kidney" in scientific writings such as "kidney medicine" or "kidney replacement therapy", other experts have advocated preserving the use of renal and nephro as appropriate including in "nephrology" and "renal replacement therapy", respectively.
Internal medicine, also known as general internal medicine in Commonwealth nations, is a medical specialty for medical doctors focused on the prevention, diagnosis, and treatment of internal diseases in adults. Medical practitioners of internal medicine are referred to as internists, or physicians in Commonwealth nations. Internists possess specialized skills in managing patients with undifferentiated or multi-system disease processes. They provide care to both hospitalized (inpatient) and ambulatory (outpatient) patients and often contribute significantly to teaching and research. Internists are qualified physicians who have undergone postgraduate training in internal medicine, and should not be confused with "interns", a term commonly used for a medical doctor who has obtained a medical degree but does not yet have a license to practice medicine unsupervised.
Human vasopressin, also called antidiuretic hormone (ADH), arginine vasopressin (AVP) or argipressin, is a hormone synthesized from the AVP gene as a peptide prohormone in neurons in the hypothalamus, and is converted to AVP. It then travels down the axon terminating in the posterior pituitary, and is released from vesicles into the circulation in response to extracellular fluid hypertonicity (hyperosmolality). AVP has two primary functions. First, it increases the amount of solute-free water reabsorbed back into the circulation from the filtrate in the kidney tubules of the nephrons. Second, AVP constricts arterioles, which increases peripheral vascular resistance and raises arterial blood pressure.
Cilostazol, sold under the brand name Pletal among others, is a medication used to help the symptoms of intermittent claudication in peripheral vascular disease. If no improvement is seen after 3 months, stopping the medication is reasonable. It may also be used to prevent stroke. It is taken by mouth.

It is one of the largest and oldest institutions of its kind in Romania. The university uses the facilities of over 20 clinical hospitals all over Bucharest.
Allied Academies is a reportedly fraudulent corporation chartered under the laws of North Carolina. Its postal address is in London, United Kingdom. It presents itself as an association of scholars, with supporting and encouraging research and the sharing and exchange of knowledge as its stated aims. The organization consists of 30 affiliate academies, which provide awards to academics and publish academic journals both online and in hard copy for members. Since 2015 the organization has been listed on Jeffrey Beall's list of "potential, possible, or probable predatory scholarly open-access publishers". It is in a partnership with OMICS Publishing Group which uses its website and logo. In 2018, OMICS owner Srinubabu Gedela declared that he had informed the Nevada court that Allied Academies was a subsidiary of OMICS International. During a conference in 2018, they falsely listed a prominent chemist among its organizing committee who had not agreed to this and was not affiliated with Allied Academies.

Vasopressin infusions are in use for septic shock patients not responding to fluid resuscitation or infusions of catecholamines to increase the blood pressure while sparing the use of catecholamines. These argipressins have much shorter elimination half-life than synthetic non-arginine vasopresines with much longer elimination half-life of many hours. Further, argipressins act on V1a, V1b, and V2 receptors which consequently lead to higher eGFR and lower vascular resistance in the lungs. A number of injectable arginine vasopressins are in clinical use in the United States and the European Union. Pitressin among others, is a medication most commonly used in the treatment of frequent urination, increased thirst, and dehydration such as that resulting from diabetes insipidus, which causes increased and diluted urine. It is used to treat abdominal distension following some surgeries, and in stomach roentgenography. Vasopressin is a hormone that affects the kidneys and reduces urine flow.

Angiotensin II is a medication that is used to treat hypotension resulting from septic shock or other distributive shock. It is a synthetic vasoconstrictor peptide that is identical to human hormone angiotensin II and is marketed under the brand name Giapreza. The Food and Drug Administration approved the use of angiotensin II in December 2017 to treat low blood pressure resulting from septic shock.
Vasodilatory shock, vasogenic shock, or vasoplegic shock is a medical emergency belonging to shock along with cardiogenic shock, septic shock, allergen-induced shock and hypovolemic shock. When the blood vessels suddenly relax, it results in vasodilation. In vasodilatory shock, the blood vessels are too relaxed leading to extreme vasodilation and blood pressure drops and blood flow becomes very low. Without enough blood pressure, blood and oxygen will not be pushed to reach the body's organs. If vasodilatory shock lasts more than a few minutes, the lack of oxygen starts to damage the body's organs. Vasodilatory shock like other types of shock should be treated quickly, otherwise it can cause permanent organ damage or death as a result of multiple organ dysfunction.
