Comparative evaluation of microleakage in Class II cavities restored with snowplow technique using flowable or preheated packable bulk-fill composite resin as gingival increment by dye extraction method: An study.

Context: One of the undesirable characteristics of dental composite resin is the polymerization shrinkage and the associated microleakage. The snowplow technique of placement and the preheating of the composite resins are methods to minimize microleakage.

Aim: The aim of this study was to comparatively evaluate microleakage in Class II cavities restored with snowplow technique using either preheated packable or flowable bulk-fill composite resin.

Fungal Rhinosinusitis: An integrated diagnostic approach.

Classification of fungal rhinosinusitis (FRS) based on histomorphology and clinical presentation aids in early diagnosis and prompt patient management. In this retrospective observational study, clinicopathologic findings in patients diagnosed with fungal rhinosinusitis between January 2019 and December 2021 were evaluated. Clinical and imaging findings were retrieved from hospital records; slides from routine and histochemical studies were reviewed, and the cases were classified into non-invasive [fungal ball (FB) and allergic fungal rhinosinusitis (AFRS)] and invasive FRS [acute invasive fungal rhinosinusitis (AIFRS), chronic invasive fungal rhinosinusitis (CIFRS) and chronic invasive granulomatous fungal rhinosinusitis (CGFRS)].

Role of H3K27me3 and Ki-67 Labeling Index in Assessing the Biological Behavior of Meningiomas.

Background: Meningiomas are neoplasms primarily originating from arachnoid cells and are classified into 3 grades (1, 2, and 3) based on histological features according to the World Health Organization classification. However, this classification system is imperfect especially for grade 1 and 2 meningiomas as many grade 1 tumors recur. Meningiomas are hence a histologically diverse class of tumors exhibiting more unpredictable behavior.

Bioactive carbohydrate polymers from marine sources as potent nutraceuticals in modulating obesity: a review.

The majority of bioactive polysaccharides are present in some marine creatures. These polysaccharides are considered as promising anti-obesity agents, their anti-obesity properties involve a number of mechanisms, including suppression of lipid metabolism and absorption, impact on satiety, and prevention of adipocyte differentiation. Obesity is linked to type 2 diabetes, cardiovascular disease, and other metabolic syndromes.
