Background: Primary lung cancer is the leading cause of cancer death in the United States. Most lung cancers are diagnosed in an outpatient setting, but a subset requires intraoperative diagnosis. Two intraoperative diagnostic methods are available, frozen section (FS) and fine needle aspiration (FNA) cytology.

Methods: Surgical specimens involving a frozen section diagnosis over a 3-year period were retrospectively reviewed. Glass slides were reviewed on cases with discordance.
Primary melanoma of the antrum is a rare and aggressive disease. Diagnosis requires a correlation between the patient's history, tumor histopathology, and immunohistochemistry. Surgery and mutation-targeted treatments may improve overall survival.

- Aquamin, a natural multi-mineral product rich in calcium and magnesium, was studied to see if it could improve the colonic barrier in patients with ulcerative colitis (UC) by utilizing colonoid cultures from their biopsies.
- The study involved incubating these colonoids with or without Aquamin for two weeks, analyzing changes in barrier proteins and structure using advanced microscopy and proteomic techniques.
- Results showed some positive effects, including increased expression of differentiation-related proteins and tight junctions, as well as improved structural features, suggesting that Aquamin may enhance barrier function in UC-affected tissue.
Article Synopsis
- The study aimed to evaluate the effects of calcium and a multi-mineral product called Aquamin on the growth and differentiation of colonoid cultures from normal human colon tissue.
- Researchers maintained colonoid cultures in low-calcium and higher calcium conditions, analyzing growth, morphology, and protein expression after two weeks.
- Results showed that normal colonoids naturally differentiated even without calcium supplementation, while both calcium alone and Aquamin enhanced proteins related to tissue integrity, but had minimal additional effects on cell growth and differentiation.
Article Synopsis
- In this study, researchers compared the effects of Aquamin versus calcium on human colon adenomas grown in lab cultures, finding that both improved cell differentiation compared to control.
- Aquamin at a lower calcium concentration also promoted differentiation but was less effective, while specific proteins related to cell growth and differentiation were influenced more favorably by Aquamin than by calcium alone.
Pre-examination stress in second year medical students in a government college.

Background: Pre-examination Stress is a common condition faced by students prior to exams and is quite predominant among medical students. Many studies have been conducted to assess the impact of stress on students prior to examinations. This study however aims to determine the behavioural and physiological changes occurring in the second year medical students during the pre-examination period.
