Mast cells and factor XIIIa+ dendrocytes in actinic cheilitis and lip squamous cell carcinoma.

There is an interaction between dendrocytes and mast cells in the skin. However, in elastosis-related diseases such as actinic cheilitis (AC) and lower lip squamous cell carcinoma (LLSCC), this interaction remains unknown. We investigated the presence of intact and degranulated mast cells in AC and LLSCC.

Soft-tissue keratocyst: report of 3 new cases from Brazil.

Objective: To describe the clinicopathological features of 3 new cases of soft-tissue keratocyst (STK) of the buccal mucosa from Brazil.

Materials And Methods: Clinical data from 3 patients diagnosed with STK were obtained from the archives of the Laboratory of Oral Pathology at the Federal University of Rio de Janeiro- Brazil from 2020 to 2023. Two oral pathologists reviewed conventional hematoxylin and eosin-stained slides of each case.

Insights into incipient oral squamous cell carcinoma: a comprehensive south-american study.

Background: To describe demographic and clinicopathological aspects of a South-American cohort of incipient oral squamous cell carcinoma patients.

Material And Methods: A cross-sectional, observational study was performed to assess demographic and clinicopathological characteristics of incipient oral squamous cell carcinoma patients from 6 South-American institutions.

Results: One hundred and seven patients within the histopathological spectrum of incipient oral squamous cell carcinoma (in-situ and microinvasive) were included.

Development and Characterization of Symbiotic Buffalo Petit Suisse Cheese Utilizing Whey Retention and Inulin Incorporation.

This study presents the development and characterization of a novel buffalo Petit Suisse cheese, enhanced with symbiotic properties through an innovative whey retention method and incorporating inulin and xanthan gum. The research focused on assessing the cheese's physicochemical properties, shelf life, lactic acid bacteria viability, syneresis behavior, and the impact of varying concentrations of functional ingredients. The addition of inulin and xanthan gum, following a design of experiments, significantly influenced the cheese's texture and consistency.

Concentration and thickness of sea ice in the Weddell Sea from SSM/I passive microwave radiometer data.

This study evaluated feasibility statistically and analyzed, during the freezing period, the relationship between brightness temperature (Tb) data of the 37V polarisation and the GR3719 (Gradient Ratio 37V and 19V) obtained by Special Sensor Microwave/Imager from F11 and F13 satellites with sea ice thickness (SIT) data obtained in the Weddell Sea through Antarctic Sea Ice Processes and Climate program. The multiple linear regression (MLR) was applied at 1,520 points, with 70% of these points being randomly separated to generate the MLR and 30% to carry out the validation. To perform the temporal mapping, the MLR was applied only to pixels with sea ice concentration (SIC) ≥ 90%, obtained through the fraction image calculated from the spectral linear mixing model (SLMM) using the Tb in the channels and polarizations 19H, 19V and 37V.
