Changes in the solubility (in water or in 1% sodium dodecyl sulfate plus 1% ␤-mercaptoethanol), isoelectric point, and degree of browning were followed for a range of food proteins when they were heated to 105 to 145 ЊC at 3 relative humidities (RH). In general, there is a decrease in solubility with increasing RH and temperature of heating, but most proteins also showed an increase in solubility on extensive heating. The order for the proteins, based on the temperatures at which an increase in solubility occurred was: gelatin Ͻ gluten Ͻ soya isolate, sodium caseinate Ͻ egg albumin, bovine serum albumin Ͻ whey isolate, milk powder, ␤-lactoglobulin. The bonds that could be formed and broken during this thermal treatment are considered.

Nicotine was separated from eggplant and green pepper seeds (Solanaceous) by High Performance Liquid Chromatography (HPLC).The concentration of nicotine in the eggplant extract (0.871-0.877 μg/ml) was determined by injecting standard material with 0.5 and 1.5 μg/ml, while the concentrations of nicotine in green pepper extract (0.613-0.618 μg/ml) was determined when the standard material was injected with 0.5 and 1.5 μg/ml. The qualitative chemical data was calculated from derivations of the standard material. Nicotine concentration was measured qualitatively in both extracts through the calibration curve and method of the standard addition. This technique has high accuracy and compatibility, bringing the proportion of relative recovery percentage of nicotine extracted from eggplant seeds to 95.880-103.104% and relative error of -4.119-3.104%. Relative recovery percentage   of nicotine extracted from green pepper seeds was 97.284 -103.518 % and relative error was -2.716-3.518%.

Introduction: Chronic rhinosinusitis with nasal polyposis (CRSwNP) is an inflammation of the nose and paranasal sinus (PNS) mucosa for at least 12 weeks with the formation of nasal polyps. This is a multi-factorial disease. Nasal polyposis represents 4% of the population. Few studies have looked at the histopathological changes in ethmoid mucosa and compared them with those of the mucosa of the nasal septum, inferior turbinate (IT), and middle turbinate (MT) in patients with CRS. Objective: To compare clinical and histopathological findings of the middle turbinate and ethmoidal polyp in CRSwNP patients refractory to medical treatment. Methods: Forty patients with CRSwNP refractory to treatment were included. Endoscopic and histopathological findings of MT and ethmoid sinus samples were compared. Results: By endoscopic(macroscopic) examination, there was a statistically significant difference between MT and ethmoidal polyp. Polyps in the ethmoid were present in all cases. Polypoidal MT mucosa was present in a quarter of patients. In the rest of the patients, the MT mucosa was edematous or normal. By microscopic examination, there was no statistically significant difference between the two sites in the degree of basement membrane (BM) thickness, goblet cell hyperplasia, eosinophils, and polymorphs. Statistically, a significant difference was present in the degree of sub-epithelial edema, the number of sub-mucous glands, and lymphocytes. Conclusion: Although MT does not share the macroscopic changes with the ethmoid sinus in patients with CRSwNP, at the microscopic level, both sites share the pathologic changes to a far extent. It is better to address the MT in the medical and surgical management of CRSwNP for better results.
