The interest in whey and whey preparations has considerably increased in recent years. Whey and whey preparations are the so-called "forgotten treasure" and, because of their unique properties, they have been "rediscovered" and have been increasingly frequently and successfully used by various production plants in the food industry. They have also been eagerly purchased by consumers who are aware of the role of whey preparations in adequate human nutrition. For many years, there has been a tendency in the food processing industry to use substitutes of ingredients in recipes of many products. This situation can be observed in the case of foods with reduced fat and sugar, or products for lacto-ovo-vegetarians. Whey -and more specifi cally, its preparations -can also be used as a substitute. According to many literature sources, its use can have a positive impact not only on the consumers' health but also on the fi nances of many companies, by reducing the costs of raw materials, and thus production costs. This review paper presents selected uses of whey and whey preparations in the food industry. The uses of whey discussed include: meat and meat products, reduced-fat products, yoghurts and ice creams, cheeses, bakery products, confectionery and pastry products, infant formulas, and whey drinks.

Introduction: According to statistics, gastric cancer remains one of the most common causes of death due to neoplastic disease in the world's population. It is a common conception that this type of cancer mostly affects people in their fifth or sixth decade of life. So, when it comes to young people, for example in their twenties or early thirties, who present to a doctor with symptoms suggesting a cancer of the gastrointestinal tract, these are quite often ignored because of their young age.
IntroductionColorectal cancer is the second most common cancer in terms of incidence in Poland. It is also the second most common cause of cancer deaths in men and the third women. In 75–80% of cases, depending on sources, it is of an occasional nature, and in the remaining 20–25% it has a hereditary character.AimTo compare the levels of E-cadherin in blood serum with some histopathological and clinical features. E-cadherin is an adhesion molecule, loss of function of which is suspected to influence both cancer progression and metastasis.Material and methodsThe study group comprised 48 patients diagnosed with colorectal cancer treated surgically in the Second Department of General and Gastroenterological Surgery, Medical University Hospital in Bialystok.ResultsAs has been shown here, there is no statistically significant relationship between the levels of E-cadherin in blood serum and the possible prognosis to the progression of colorectal cancer. However, it was indicated that there appears to be a statistically significant relationship between blood serum E-cadherin levels and the levels of alanine aminotransferase and aspartate aminotransferase in patients with colorectal cancer.ConclusionsThe authors suggest that this significance may require further study.
Introduction As one of the most common causes of cancer deaths in Poland, colorectal cancer, remains a mystery when factors affecting local and distant lymph node metastasis are concerned. Aim In this study the authors have analysed possible correlations between the number of regional (and distant) lymph nodes affected by cancer, location and stage of the primary tumour, levels of oncological markers CA19-9 and CEA, and the patients age, sex, body mass index (BMI), and other clinical symptoms. Material and methods A special questionnaire was created for this study, and a group of 100 men and women was selected. All patients in the study group had undergone surgery due to colorectal cancer. Results There were no statistically significant relationships between age, and number and location of metastases ( p > 0.05). Primary tumour assessment did not show a statistically significant relationship with the presence of metastases to regional lymph nodes ( p > 0.05). There was also no statistically significant correlation between tumour localisation and lymph node metastases ( p > 0.05) or between tumour size, BMI, occurrence of physical symptoms, and involvement of distant lymph nodes ( p > 0.05). The highest CEA was observed in a patient with nine regional lymph node metastases (612.46 ng/ml) and the lowest in one with metastases to two regional nodes (0.2 U/ml). CEA value above 5 ng/ml was found in 35.74% of patients with regional lymph node metastases. A statistically significant relationship was reported ( p < 0.05). Conclusions The location of the primary tumour, and its pathological stage and size does not seem to have a direct correlation with the occurrence of regional lymph node metastases. Metastasis to distant lymph nodes seems to be a consequence of metastases in regional nodes. Elevated CEA tumour marker values are significantly related to metastases in regional lymph nodes. The elevation of CA 19-9 and CEA tumour markers significantly correlates with the presence of metastasis to distant lymph nodes. The location of the primary tumour determines the formation of metastases in distant lymph nodes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
