The genetic variations in synaptic and post-receptor signalling proteins have direct effect on the process of serotonergic neurotransmission. We aimed to investigate the genetic association of serotonin transporter (SERT) 5-hydroxytryptamine transporter-linked promoter region (5-HTTLPR) polymorphism and migraine risk in South-Indian population.

Primary idiopathic chylopericardium managed by uniportal VATS.

Chylopericardium is very rarely encountered in clinical practice. The common causes are post cardiac or thoracic surgery and neoplasms of the mediastinum. Most of the time, no cause is attributed and it is labelled as primary idiopathic chylopericardium.

Engineering Antioxidant Surfaces for Titanium-Based Metallic Biomaterials.

Prolonged inflammation induced by orthopedic metallic implants can critically affect the success rates, which can even lead to aseptic loosening and consequent implant failure. In the case of adverse clinical conditions involving osteoporosis, orthopedic trauma and implant corrosion-wear in peri-implant region, the reactive oxygen species (ROS) activity is enhanced which leads to increased oxidative stress. Metallic implant materials (such as titanium and its alloys) can induce increased amount of ROS, thereby critically influencing the healing process.

2D-DIGE-Based Proteomic Profiling with Validations Identifies Vimentin as a Secretory Biomarker Useful for Early Detection and Poor Prognosis in Oral Cancers.

Oral tongue squamous cell carcinoma (OTSCC) is an aggressive cancer with high morbidity and mortality rates, despite multimodality management. There are currently no clinically relevant molecular markers that identify patients at higher risk of recurrence and failure. We undertook 2D-DIGE proteomic profiling to study the differentially expressed proteins in OTSCC evaluating their role in prognosis.

Exome Sequencing with Validations and Expression of p16/CDKN2A Shows no Association with HPV in Oral Cancers.

Purpose: Despite many studies attributing HPV infection to oropharyngeal tumorigenesis, its involvement in non-oropharyngeal cancers is ambiguous. We have evaluated the mutation profile of p16 along with protein expression and correlated it with the HPV status in oral cancers.

Methods: Somatic mutations in p16 were studied by exome sequencing (n=25) and validated by Sequenom Mass spectrometry (n=50).

Genetic predisposition of gene polymorphism in South-Indian Migraineurs and meta-analysis.

Donor-π-acceptor type beta-substituted porphyrin dyads and their Zn(II) and Pd(II) complexes were characterized by MALDI-MS, NMR, UV-vis absorption, fluorescence and cyclic voltammetry techniques. The S emission dynamics were analyzed by time-resolved spectroscopy (TCSPC); dyads exhibited efficient energy transfer up to 93% from beta-donors (N-butylcarbazole or triphenylamine group) to the porphyrin core.

Monitoring global changes in chromatin compaction states upon localized DNA damage with tools of fluorescence anisotropy.

In the eukaryotic nucleus, DNA, packaged in the form of chromatin, is subject to continuous damage. Chromatin has to be remodeled in order to repair such damage efficiently. But compact chromatin may also be more refractory to damage.

Impact of Health Care Reform on Technology and Innovation.

The medical device industry has long been subject to criticism for lack of price transparency and minimal regulations surrounding device approval, which have functioned as barriers to providing quality and cost-effective care. Recent health care reforms aimed at overcoming these barriers, including improving market approval regulations, increasing postmarket surveillance, and using comparative effectiveness research, have drastically changed industry practices. These reforms have also prompted increasingly cost-aware health care practices, which have encouraged new trends in medical device innovation such as frugal innovation and deinstitutionalization.

Hematopoietic PBX-interacting protein is a substrate and an inhibitor of the APC/C-Cdc20 complex and regulates mitosis by stabilizing cyclin B1.

Proper cell division relies on the coordinated regulation between a structural component, the mitotic spindle, and a regulatory component, anaphase-promoting complex/cyclosome (APC/C). Hematopoietic PBX-interacting protein (HPIP) is a microtubule-associated protein that plays a pivotal role in cell proliferation, cell migration, and tumor metastasis. Here, using HEK293T and HeLa cells, along with immunoprecipitation and immunoblotting, live-cell imaging, and protein-stability assays, we report that HPIP expression oscillates throughout the cell cycle and that its depletion delays cell division.
