Role of artificial intelligence in cancer detection using protein p53: A Review.

Normal cell development and prevention of tumor formation rely on the tumor-suppressor protein p53. This crucial protein is produced from the Tp53 gene, which encodes the p53 protein. The p53 protein plays a vital role in regulating cell growth, DNA repair, and apoptosis (programmed cell death), thereby maintaining the integrity of the genome and preventing the formation of tumors.

The generation of stable microvessels in ischemia is mediated by endothelial cell derived TRAIL.

Reversal of ischemia is mediated by neo-angiogenesis requiring endothelial cell (EC) and pericyte interactions to form stable microvascular networks. We describe an unrecognized role for tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) in potentiating neo-angiogenesis and vessel stabilization. We show that the endothelium is a major source of TRAIL in the healthy circulation compromised in peripheral artery disease (PAD).

Novel modifications of PARP inhibitor veliparib increase PARP1 binding to DNA breaks.

Catalytic poly(ADP-ribose) production by PARP1 is allosterically activated through interaction with DNA breaks, and PARP inhibitor compounds have the potential to influence PARP1 allostery in addition to preventing catalytic activity. Using the benzimidazole-4-carboxamide pharmacophore present in the first generation PARP1 inhibitor veliparib, a series of 11 derivatives was designed, synthesized, and evaluated as allosteric PARP1 inhibitors, with the premise that bulky substituents would engage the regulatory helical domain (HD) and thereby promote PARP1 retention on DNA breaks. We found that core scaffold modifications could indeed increase PARP1 affinity for DNA; however, the bulk of the modification alone was insufficient to trigger PARP1 allosteric retention on DNA breaks.

The Prognostic, Diagnostic, and Therapeutic Potential of TRAIL Signalling in Cardiovascular Diseases.

TNF-related apoptosis-inducing ligand (TRAIL) was originally discovered, almost 20 years ago, for its ability to kill cancer cells. More recent evidence has described pleiotropic functions, particularly in the cardiovascular system. There is potential for TRAIL concentrations in the circulation to act as prognostic and/or diagnostic factors for cardiovascular diseases (CVD).

A comprehensive study of p53 protein.

The protein p53 has been extensively investigated since it was found 43 years ago and has become a "guardian of the genome" that regulates the division of cells by preventing the growth of cells and dividing them, that is, inhibits the development of tumors. Initial proof of protein existence by researchers in the mid-1970s was found by altering and regulating the SV40 big T antigen termed the A protein. Researchers demonstrated how viruses play a role in cancer by employing viruses' ability to create T-antigens complex with viral tumors, which was discovered in 1979 following a viral analysis and cancer analog research.

Accidental Pathological Findings in Asymptomatic Maxillary Sinuses in Patients Referred for Head and Neck Cone-Beam Computed Tomography: A Cross-sectional Study Analysis.

Background: The aim of the present study was to detect the prevalence of accidental pathological findings in asymptomatic maxillary sinuses in patients referred for head and neck cone-beam computed tomography (CBCT) examination for varied reasons.

Methods: The present cross-sectional study included a detailed analysis of CBCT scans of 150 patients aged between 18 and 70 years reporting for varied dental complaints for detecting accidental pathological findings in maxillary sinuses while the patients did not have any complaint pertaining to sinuses.

Results: The findings of the present study revealed 58% patients to have pathological findings in maxillary sinuses while they were asymptomatic for sinuses.

Calcifying Epithelial Odontogenic Cyst of Maxilla: A Clinical and Histological Rarity with Literature Review.

A cyst is defined as a pathological cavity which may or may not have an epithelial lining and which has a fluid, semi-fluid, or gaseous contents and is not formed by the accumulation of pus. The calcifying epithelial odontogenic cyst (CEOC) was first reported by Gorlin et al. in 1962.

Serum ceruloplasmin as cancer marker in oral pre-cancers and cancers.

Background And Aim: Oxidative stress leads to a compensatory increase in levels of serum ceruloplasmin in patients with such imbalances. Greater than normal serum ceruloplasmin levels are noticed in numerous cancers including the leukemias and Hodgkin's lymphoma. The purpose of the present study was to estimate and evaluate the efficacy of serum ceruloplasmin levels as a potential biomarker in the early detection of oral potentially malignant epithelial lesions (PMELs) including leukoplakia, oral submucous fibrosis (OSMF), and oral squamous cell carcinoma (OSCC) patients.

Impairment of olfactory and gustatory sensations in severe acute respiratory syndrome corona virus 2 (SARS-CoV-2 virus) disease.

Severe acute respiratory syndrome corona virus 2 (SARS-CoV-2 virus) disease had first appeared in December 2019 in Wuhan, China, and since then, it has emerged as a global threat to humanity. An early diagnosis and isolation are the most significant measures required to prevent its spread. Recent anecdotal evidence has suggested impairment of olfactory and gustatory sensations associated with corona virus disease (COVID-19).

Efficacy and Safety of Intravenous Labetalol in Acute Hypertensive Crisis in Children.

Objective: To determine the efficacy and safety of intravenous (IV) labetalol in the management of hypertensive crisis in children.

Methods: A retrospective chart review of 56 consecutive children (age > 1 mo to ≤ 12 y) with hypertensive crisis admitted to a pediatric intensive care unit (PICU) from July 2009 to 2019.

Results: The proportion of children attaining the primary endpoint (target 95th percentile in > 12 to ≤ 48 h) was significantly more in the group receiving labetalol as first-line or add-on (n = 23) as compared to those not receiving labetalol (n = 33) (62% vs.

Clinical Profile and Predictors of Outcome in Children with Acute Fulminant Myocarditis Receiving Intensive Care: A Single Center Experience.

Acute myocarditis in children is associated with high morbidity and mortality, with limited data on intravenous immunoglobulin (IVIG) treatment and outcome. Our goal was to describe clinical, treatment profile, and predictors of outcome in children with acute fulminant myocarditis (AFM) receiving intensive care. Case records of 120 children with clinical diagnosis of acute myocarditis from January 2008 to December 2018 were analyzed retrospectively.

TRAIL signals, extracellular matrix and vessel remodelling.

The extracellular matrix (ECM) is an essential part of the vasculature, not only providing structural support to the blood vessel wall, but also in its ability to interact with cells to regulate cell phenotype and function including proliferation, migration, differentiation and death - processes important in vascular remodelling. Increasing evidence implicates TNF-related apoptosis-inducing ligand (TRAIL) signalling in the modulation of vascular cell function and remodelling under normal and pathological conditions such as in atherosclerosis. TRAIL can also stimulate synthesis of multiple ECM components within blood vessels.

A "Western Diet" promotes symptoms of hepatic steatosis in spontaneously hypertensive rats.

Systemic hypertension, characterized by elevated blood pressure ≥140/90 mm Hg, is a major modifiable risk factor for cardiovascular disease. Hypertension also associates with non-alcoholic fatty liver disease (NAFLD), which is becoming common due to a modern diet and lifestyle. The aim of the present study was to examine whether a high-fat "Western" diet had effects on hypertension and associated NAFLD.

Vascular transcriptome landscape of Trail mice: Implications and therapeutic strategies for diabetic vascular disease.

Circulating plasma TRAIL levels are suppressed in patients with cardiovascular and diabetic diseases. To identify novel targets in vascular metabolic diseases, genome-wide transcriptome of aortic tissue from Trail versus Trail mice were interrogated. We found 861 genes differentially expressed with TRAIL deletion.

Comparison of clinical efficacy of methylprednisolone and serratiopeptidase for reduction of postoperative sequelae after lower third molar surgery.

Background: Surgical removal of mandibular third molars results in some degree of post-operative pain, swelling and trismus. These can be controlled by proper administration of local anesthesia, careful bone removal, minimal trauma to adjacent soft tissues and administration of methylprednisolone and serratiopeptidase drugs. The aim of the present study was to compare the efficacy of methylprednisolone and serratiopeptidase in controlling post-operative pain, swelling and trismus after surgical removal of impacted mandibular third molars.

Brown tumour of posterior maxilla associated with polydactyly, syndactyly and cardiac anomalies: a unique case report.

Brown tumour [BT] is an uncommon, non neoplastic complication of Hyperparathyroidism [HPT]. Skeletal changes are the main consequences of this endocrine condition. HPT manifest in three categories.

Synthesis and anticancer evaluation of furfurylidene 4-piperidone analogs.

Recently different series of compounds have been designed that utilize the 1,5-diaryl-3-oxo-1,4-pentadinenyl pharmacophore for the development of novel cytotoxic and anticancer agents. These compounds interact with cellular thiols and thiols are not part of nucleic acids. Hence, these compounds are free from the problem of mutagenicity and carcinogenicity.

Acute respiratory distress during paradoxical reaction to antituberculous therapy in an 8-month-old child.

Paradoxical reaction during antituberculosis treatment (ATT) is commonly seen as tuberculous lymphadenitis of peripheral lymph node, cerebral tuberculomas, pulmonary infiltrates, and pleural disease. This phenomenon is more commonly associated with extrapulmonary tuberculosis and disseminated tuberculosis. Respiratory distress, as presentation of paradoxical reaction, is rare.

Oral immunization with a live coxsackievirus/HIV recombinant induces gag p24-specific T cell responses.

Background: The development of an HIV/AIDS vaccine has proven to be elusive. Because human vaccine trials have not yet demonstrated efficacy, new vaccine strategies are needed for the HIV vaccine pipeline. We have been developing a new HIV vaccine platform using a live enterovirus, coxsackievirus B4 (CVB4) vector.
