Primary Objective: This is a study to investigate the feasibility of harvesting, expanding, and selecting T lymphocytes from cancer patients and healthy volunteers. The preliminary objective of this study is aimed at selecting PD-1+ and CTLA4+ T cells and other cellular fractions from peripheral blood of cancer patients and healthy volunteers by using specific conjugated antibodies, evaluating their functional ex vivo anti-tumor cytotoxicity against targeted autologous tumor cells.

Demonstrate the bioequivalence in 1 study, in fasting condition of two formulations of clonazepam 2 mg Tablets / tablets immediate release in order to establish that there are no significant pharmacokinetic differences.

The first objective of the project consists in the preclinical validation of new possible molecular targets associated with intratumoral T regulatory cells. The second objective consists in the selection of monoclonal antibodies with therapeutic potential, specific for the selected targets.

Two bioequivalence studies of Pentoxifylline will be carried out in 40 healthy subjects, the first in a fasting condition 40 healthy subjects, the first in fasting condition and the second in postprandial condition. postprandial condition, the two studies follow the same design: Complete crossover design, randomized, comparative of two study formulations, in single dose of 400 mg of Pentoxifylline sustained release tablets, 2 periods, with a washout time of 7 days between doses, the 7 days between doses, participation as a subject in these studies involves a risk studies involves a higher than minimal risk for subjects.

The goal of this study is to investigate whether a seaweed derived food additive, carrageenan, has an impact on the human gut microbiome in vivo. The primary purpose is to assess whether consumption of a carrageenan containing product for 4 weeks can alter the bacterial composition of the gut microbiome in healthy individuals and whether the addition of a prebiotic fibre, inulin, to the product has an enhanced beneficial impact of the gut composition. The main questions to answer are: Does the consumption of a confectionary item containing carrageenan and inulin lead to a positive impact on the faecal microbial community when compared to the confectionary item containing no carrageenan and no inulin (placebo)? Participants will be asked to consume 2 gummy sweets for 4 week period and provide stool and urine samples on 3 occasions over a 9 week period. Does the consumption of a confectionary item containing carrageenan and inulin improve gastrointestinal comfort measured using overall SHS-GI score when compared to baseline measurements recorded during run in period?
