J. Silvio Gutkind

Associate Director, Basic ScienceJ. Silvio Gutkind received his Ph.D. in Pharmacy and Biochemistry from the University of Buenos Aires, Argentina. He was trained as a post-doctoral fellow at the NIMH and NCI, and joined the National Institute of Dental and Craniofacial Research (NIDCR), NIH, where he is currently the Chief of the Oral and Pharyngeal Cancer Branch. Dr. Gutkind is a national and international leader in the study of basic signal transduction mechanisms in cancer. He is recognized for his pioneering research aimed at unraveling the complexity of the intracellular signaling circuitry by which cell surface receptors and Rho GTPases control the nuclear expression of growth promoting genes, thereby promoting normal and malignant growth. His recent studies have addressed the role of mutant G proteins and G protein coupled receptors in cancer initiation, with emphasis on ocular melanoma, colon and skin cancer, and AIDS-malignancies. His multidisciplinary team has also made outstanding contributions to the study of the aberrant signaling circuitries driving head and neck cancer progression, including the seminal finding that most head and neck cancer lesions display persistent activation of the PI3K–AKT–mTOR pathway. His team is now exploiting the emerging information for the development of novel mechanism-based anti-cancer therapies. In particular, Dr. Gutkind is currently leading a multi-institutional effort aimed at exploring the clinical benefits of trea...

It is currently recognized that in addition to the major impact of human papillomavirus (HPV) infection in females, HPV causes considerable disease in men at the genitals, anal canal, and oropharynx. Specifically, genital HPV infections may progress to genital warts and penile carcinoma. Although studies concerning the natural history of HPV infections and associated neoplasias have mainly focused on women, during the last 2 decades considerable attention has been given in further understanding these infections in men. The HIM (HPV infection in men) Study, the only prospective multicenter study of male HPV natural history,...

Sexual intercourse is regarded as the primary route of human papillomavirus (HPV) transmission. Reported rates of the genotype-specific genital concordance of HPV infection among heterosexual partners vary. Most studies have evaluated only male/female genital transmission, but lately, the oral region has gained interest because of a rising trend of HPV-associated oropharyngeal cancer. Risk factors for type-specific concordance have been reported as an increasing number of younger couples, persistent HPV infection, higher frequency of sexual intercourse, rising number of spouse ’s lifetime sexual partners, and sexual ...

OVs can revert cancer-associated immune suppression and initiate clinically meaningful antitumor immune responses. OVs and their resultant immunological events can act at both primary and metastatic sites. Thus, OVs can be exploited for cancer gene therapies and immunotherapies alone or in combination with other interventions, including immune checkpoint blockade.

In this study, three non-linear indices consist of compression, one-dimensional (1D) and two-dimensional (2D) fractal dimensions are used for the determination of the malignancy or benignity of cancer tumours in breast thermograms. On the other hand, by developing the high-precision infrared cameras as well as new methods of image processing, biomedical thermography images have found a prominent position among the others. Furthermore, cancerous tissue can be affected by the laser. In this study, in order to treat the cancerous lesion identified by breast thermograms, the laser parameters are designed. The basis of controll...

Prediction of drug synergy score is an ill-posed problem. It plays an efficient role in the medical field for inhibiting specific cancer agents. An efficient regression-based machine learning technique has an ability to minimise the drug synergy prediction errors. Therefore, in this study, an efficient machine learning technique for drug synergy prediction technique is designed by using ensemble based differential evolution (DE) for optimising the support vector machine (SVM). Because the tuning of the attributes of SVM kernel regulates the prediction precision. The ensemble based DE employs two trial vector generation tec...
