An insight into the mechanistic role of (-)-Ampelopsin F from Vatica chinensis L. in inducing insulin secretion in pancreatic beta cells.

Resveratrol oligomers, ranging from dimers to octamers, are formed through regioselective synthesis involving the phenoxy radical coupling of resveratrol building blocks, exhibiting remarkable therapeutic potential, including antidiabetic properties. In this study, we elucidate the mechanistic insights into the insulin secretion potential of a resveratrol dimer, (-)-Ampelopsin F (AmF), isolated from the acetone extract of Vatica chinensis L. stem bark in Pancreatic Beta-TC-6 cell lines.

Metabolomic analysis for disclosing nutritional and therapeutic prospective of traditional rice cultivars of Cauvery deltaic region, India.

Traditional rice is gaining popularity worldwide due to its high nutritional and pharmaceutical value, as well as its high resistance to abiotic and biotic stresses. This has attracted significant attention from breeders, nutritionists, and plant protection scientists in recent years. Hence, it is critical to investigate the grain metabolome to reveal germination and nutritional importance.

Long-standing undiagnosed foreign body aspiration with concomitant pulmonary tuberculosis in an Immunocompetent man.

Foreign body aspiration is a rare clinical finding in adults, among which very few are reported, probably due to absence of classical clinical features in adults when compared to children and due to lack of awareness. We present a 57-year-old with chronic productive cough who was diagnosed to have pulmonary tuberculosis (TB), complicated by long-standing foreign body in the tracheobronchial tree. There are many cases reported in literature where there have been misdiagnosis with respect to pulmonary TB as foreign body or foreign bodies as pulmonary TB.

Discovery, synthesis and approach of pyrrolo [3,4-]pyrroles as SARS-CoV-2 m inhibitors.

Intelligent predictions of Covid disease based on lung CT images using machine learning strategy.

Covid or Corona Virus, a term ruling the world from past two years and causes a huge destruction in all countries. One of the most important Covid disease identification method is Lung based Computed Tomography (CT) image scanning, in which it provides an effective disease identification means in clear manner. However, this Lung CT image based disease detection principles are complex to health care representatives and doctors to predict the Covid disease accurately.

Pituitary Tuberculoma Masquerading as a Pituitary Adenoma: Interesting Case Report and Review of Literature.

We present a rare case of a pituitary tuberculoma masquerading as pituitary adenoma with pituitary apoplexy-like presentation in a 31-year-old female, who had symptoms suggestive of acute secondary adrenal insufficiency with secondary amenorrhea. After initial evaluation which was suggestive of pituitary adenoma, she underwent endoscopic transnasal pituitary tumor excision. Histopathology revealed features of pituitary tuberculoma.

A Rare Case of Adenoid Cystic Carcinoma of the Sphenoid Sinus Presenting with Lateral Rectus Palsy.

A rare case of adenoid cystic carcinoma arising from the sphenoid sinus causing lateral rectus palsy is presented here. Adenoid cystic carcinoma of the paranasal sinuses is an aggressive neoplasm which needs early diagnosis and treatment. Ideal treatment paradigm for paranasal sinus tumors is yet to be established.

Antidiabetic potential of phytochemicals isolated from the stem bark of Myristica fatua Houtt. var. magnifica (Bedd.) Sinclair.

Phytochemical investigation of the stem bark of Myristica fatua Houtt. led to the isolation of a new compound 1 (3-tridecanoylbenzoic acid), along with six known acylphenols (2-7).

A case-control study of plasma homocysteine levels in South Indians with and without coronary artery disease.

Background: An increased level of plasma homocysteine is being recognized as a new risk factor for coronary artery disease. Since there are not enough data about its importance in Indians with coronary artery disease, we aimed to assess the significance of plasma homocysteine as a coronary risk factor in South Indian patients.

Methods And Results: In a case-control study, fasting plasma homocysteine levels were estimated in 565 subjects, of whom 221 were cases and 344 were controls.

Increased expression of interleukin-1 beta is associated with persistence of the disease and invasion in complete hydatidiform moles (CHM).

Complete hydatidiform moles (CHM), a post-conceptual pathologic condition of the placenta, have a high prevalence rate (12/1,000 deliveries) in Kerala, India. This study addresses the expression of IL-1 alpha and beta by immunohistochemistry in relation to persistence and invasion of the disease. Mild to moderate expression of IL-1 alpha in the villous cytotrophoblasts, syncytiotrophoblasts and decidua of the first trimester in the normal placenta and all gestational ages in the molar placenta were observed.

Lack of association of gestational trophoblastic diseases (GTD) with syphilis and AIDS.

The association between human immunodeficiency virus (HIV) infection and syphilis infection as an etiological factor in Gestational Trophoblastic Disease (GTD) was investigated by means of micro-enzyme linked immunosorbent assay (Micro-ELISA) and Treposcreen-Rapid Plasma Reagin Card Test in 138 sera from patients with Gestational Trophoblastic Disease. We have found only one sample to be positive for HIV infection and one for VDRL. These findings suggest a lack of an etiologic role for the HIV and Syphilis infection in GTD.

Leucocyte adherence inhibition assay (LAI) in cancer of the oral cavity.

Antitumor immunity to oral cancer was assessed in 46 patients suffering from squamous cell carcinoma of the oral cavity using a leucocyte adherence inhibition assay (LAI). The response shown by the leucocytes of oral cancer patients to the oral cancer antigen was compared to that shown by the leucocytes from 10 normal age- and sex-matched healthy controls and 43 patients suffering from other types of cancers. Seventy-six percent of the oral cancer patients showed a high degree of leucocyte adherence inhibition in the presence of the antigen.
