Distinct methylome profile of cfDNA in AMI patients reveals significant alteration in cAMP signaling pathway genes regulating cardiac muscle contraction.

Background: The role of epigenetics in cardiovascular diseases has paved the way for innovative therapeutic approaches. Investigating epigenetic changes using cell-free DNA (cfDNA) holds substantial promise beyond mere diagnostics, especially for heart-related conditions like acute myocardial infarction (AMI), where obtaining tissue samples is a challenge. This study explores the methylation patterns of cfDNA in AMI patients and compares them with genomic DNA (gDNA) from the same individuals, aiming to evaluate the effectiveness of cfDNA as a valuable resource for studying heart-related diseases.

Maltase-glucoamylase catalyses the release of the glucose molecule in the final enzymatic reaction of starch digestion; therefore, inhibition of maltase-glucoamylase is one of the approaches in the development of therapeutics for diabetes. is commonly recommended in Ayurveda for the treatment of diabetes.

Clinical significance of SPOP and APC gene alterations in colorectal cancer in Indian population.

Speckle-Type Poz Protein (SPOP) involved in the regulation of proteasome-mediated degradation of several oncoproteins, resulting in cancer initiation and progression. Mutations in Adenomatous Polyposis Coli (APC) gene is reported in most sporadic and hereditary colorectal cancer (CRC). Identifying the cellular changes involved in carcinogenesis when APC is mutated is an important issue that needs attention.

Genetic aberration analysis of mitochondrial respiratory complex I implications in the development of neurological disorders and their clinical significance.

Growing neurological diseases pose difficult challenges for modern medicine to diagnose and manage them effectively. Many neurological disorders mainly occur due to genetic alteration in genes encoding mitochondrial proteins. Moreover, mitochondrial genes exhibit a higher rate of mutation due to the generation of Reactive oxygen species (ROS) during oxidative phosphorylation operating in their vicinity.

Molecular aspects of ABCB1 and ABCG2 in Gallbladder cancer and its clinical relevance.

The function of ABC transporters in the body is manifold; such as maintenance of homeostasis, effect on multi-drug resistance and their role in tumor initiation & progression. Evidence pointing towards the direct or indirect role of ABC transporter genes in particular; ABCB1 and ABCG2 in cancer genesis is increasing. However, their role in gallbladder cancer is unexplored.

Implication of gut microbes and its metabolites in colorectal cancer.

Background: Colorectal cancer (CRC) is the third most common cancer with a significant impact on loss of life. In 2020, nearly 1.9 million new cases and over 9,35,000 deaths were reported.

A non-invasive miRNA-based approach in early diagnosis and therapeutics of oral cancer.

Oral or mouth cancer is the 16th most common form of cancer among the world's topmost malignancies. Healthy lifestyle and control of known risk factors can reduce its incidences further. Patients succumb to oral cancer when diagnosed late and lack timely access to tertiary care.

Molecular approaches in cancer.

Cancer remains the second leading cause of death worldwide and newly diagnosed cases have increased at an alarming rate. One in every four people has a lifetime risk of being afflicted with cancer. Early diagnosis, which is essential in reducing morbidity and mortality, requires the development of highly sensitive and specific techniques to identify and monitor molecular changes for cancer-specific genetic and epigenetic markers.

Molecular pathways in periampullary cancer: An overview.

Molecular alterations in oncogenes and tumor suppressors in various signaling pathways are basis for personalized therapy in cancer. Periampullary carcinoma behaves differently from pancreatic carcinoma both in prognosis and outcome, therefore it needs special attention. Pancreatic cancer have higher incidence of nodal spread and perineural &lymphovascular invasion suggesting it biologically more aggressive tumor compared to periampullary cancer.

Diagnostic and prognostic biomarkers in colorectal cancer and the potential role of exosomes in drug delivery.

Colorectal cancer (CRC) is the third most common cancer with the second most frequent cause of death worldwide. One fourth to one fifth of the CRC cases are detected at advance stage. Early detection of colorectal cancer might help in decreasing mortality and morbidity worldwide.

Molecular markers in cancer.

Cancer remains a common health issue having significant socioeconomic burden worldwide. Despite the awareness campaigns, cancer cases continue to increase due to an aging population and lack of early detection biomarkers. Accordingly, much research has focused on non-traditional approaches which include novel imaging modalities and liquid biopsy.

Prospective Randomized Controlled Trial Comparing Adjuvant Chemotherapy vs. No Chemotherapy for Patients with Carcinoma of Gallbladder Undergoing Curative Resection.

Background: Gallbladder carcinoma (GBC) has a dismal prognosis even after curative resection. The objective of the study was to evaluate the effect of adjuvant chemotherapy in patients with GBC undergoing curative resection in a randomized control trial (RCT).

Deregulation of S1P signaling causes aberrant proliferation, affects survival, leads to angiogenesis and metastasis. Sphingolipid rheostat is crucial for cellular homeostasis.

Management of Obscurely Dilated Common Bile Duct with Normal Liver Function Tests: A Pragmatic Approach.

Objective: Dilated common bile duct (CBD) (8-15 mm) with normal liver function tests is seen not infrequently, while management of such patients is ambiguous. We propose a treatment algorithm for this cohort of patients after observing them over a period of 8 years.

Methods: Seventy-eight such patients were managed from 2009 to 2017 and categorized as: Group A-dilated CBD with post-cholecystectomy status (n = 15); B-dilated CBD with cholelithiasis (n = 34); C-dilated CBD without cholelithiasis (n = 16); D-dilated CBD with no cause identified and underwent CBD excision (n = 13).

Management of scope-induced type I duodenal perforations: Over-the-scope clip versus surgery.

Background: Scope-induced duodenal perforation is a life-threatening complication and surgery remains the standard of care. With the advent of over-the-scope clip (OTSC), scope-induced perforations are increasingly managed conservatively, though there is no study comparing this form of non-surgical treatment with surgery. We aimed to compare OTSC and surgery in the management of scope-induced perforation of the duodenum.

Cross-talk between next generation sequencing methodologies to identify genomic signatures of esophageal cancer.

The asymptomatic behaviour of esophageal cancerous cells at early stages develops advanced clinical presentation of the disease, resulting in poor prognosis and curbed intervention of therapeutic modalities. The endeavours to detect diagnostic and prognostic markers have been proven futile at the clinical platform. While several biomarkers have been investigated, including CYFRA 21-1, carcinoembryonic antigen and squamous cell carcinoma antigen, their sensitivity has not proved consistently satisfactory across the various stages of esophageal cancer.
