Role of Psychological Stress and Choroidal Thickness in Central Serous Chorioretinopathy.

Introduction: Central serous chorioretinopathy (CSCR) is a disease with a multifactorial aetiology.

Objectives: To evaluate the role of psychological stress and choroidal thickness in patients with CSCR.

Materials And Methods: This was a hospital-based, analytical cross-sectional study, conducted at Christian Medical College, Vellore, India, from 2018 February to 2019 September, after the approval of the Institutional Review Board and Ethics Committee.

An ensemble-based serial cascaded attention network and improved variational auto encoder for breast cancer prognosis prediction using data.

Breast cancer is one of the most common types of cancer in women and it produces a huge amount of death rate in the world. Early recognition is lessening its impact. The early recognition of breast cancer could convince patients to receive surgical therapy, which will significantly improve the chance of restoration.

Effect of Sanitizer on obliteration of SARS -CoV2/COVID 19: A mini review.

Corona virus is a respiratory virus which causes infectious Covid-19 (Corona Virus -2019) disease and globally the virus continues to pose major risks of mortality. It is lucid that close links are the key aspect for transitory of communicable Corona virus. Rapid research is in progress to identify prolific drugs and vaccine for Covid-19 however, it is a time consuming process.

Correlation of matrix metalloproteinase-9 expression with morphometric analysis of mucosal vasculature in oral squamous cell carcinoma, oral epithelial dysplasia, and normal oral mucosa.

Objective: Oral squamous cell carcinoma (OSCC) invades and metastasizes, by degrading the extracellular matrix (ECM) and is associated with poor prognosis. Matrix-metalloproteinase (MMP-9) can initiate ECM degradation and angiogenesis which brings a significant change in tumor microenvironment favoring tumor progression. A major thrust has been laid on understanding this key enzyme as it has significant implications for cancer therapy.

Evaluation of cannibalistic cells: a novel entity in prediction of aggressive nature of oral squamous cell carcinoma.

Objective: Cellular cannibalism is a distinctive morphologic feature exclusively seen in aggressive malignancies and is defined as a large cell enclosing a slightly smaller one within its cytoplasm. This phenomenon has been illustrated in several malignancies and is correlated well with the degree of anaplasia, invasive and metastatic potential of tumor cells. However, this marker has not been extensively studied and is often unnoticed during the routine histopathological assessment of Oral squamous cell carcinoma (OSCC).

Alkyl and Aromatic Amines as Digestive Ripening/Size Focusing Agents for Gold Nanoparticles.

Both long chain alkyl thiols and alkyl amines behave as size focusing agents for gold nanoparticles, a process that is under thermodynamic control. However, amines do not oxidize surface gold atoms while thiols do oxidize surface gold to gold(I) with evolution of hydrogen gas. Therefore, alkyl amines participate in digestive ripening by a different mechanism.

Loss of hydrogen upon exposure of thiol to gold clusters at low temperature.

Gold-acetone-dodecanethiol and gold-acetone-phenylethanethiol colloids were prepared by the solvated metal atom dispersion method. Hydrogen evolution occurred at fairly low temperature, when the melting acetone-gold solvate encountered the thiol molecules, due to S-H bond scission. The gas inside the reactor was analyzed by gas chromatography, and the moles of H(2) was determined by calibration curves obtained from a series of known concentration samples.

Size Focusing of Nanoparticles by Thermodynamic Control through Ligand Interactions. Molecular Clusters Compared with Nanoparticles of Metals.

Ligand-capped metal entities come in two sizes, (1) molecular clusters of 10-200 metal atoms and (2) nanoparticles of 2000-10000 metal atoms. In numerous cases, certain "magic sizes" have been found to be most accessible and stable, clusters of 25, 38, 55, and 102 atoms and nanoparticles of 3500-5000 atoms or 4-5 nm. The most familiar and studied system is that of gold (metal) and thiol (ligand).

Drug-induced bullous sweet syndrome with multiple autoimmune features.

Sweet syndrome (SS) (Acute Febrile Neutrophilic Dermatosis) has been reported in association with autoimmune phenomena including relapsing polychondritis, drug-induced lupus, and the development of antineutrophil cytoplasmic antibodies (ANCAs). However, a combination of these autoimmune features has not been reported. Herein, we report a case of drug-induced bullous SS with ocular and mucosal involvement, glomerulonephritis, and multiple autoimmune features including clinical polychondritis with antitype II collagen antibodies, ANCAs, antinuclear (HEp-2), and antihistone antibodies in a patient on hydralazine and carbamazepine.
