Quality Characteristics of Processed Cheese Fortified with Powder.

Background And Objective: Spirulina is a rich source of nutrients viz., essential amino acids, essential fatty acids, carotenoids and vitamins. The study was carried out to evaluate of Spirulina maxima addition as source of nutrients, antioxidants and color on processed cheese properties.

Natural peppermint-flavored cheese.

Background: The essential oils of edible and medicinal plants, herbs and spices are natural biologically ac- tive agents. Peppermint has a special position in Egyptian culture and is used as fresh or dried leaves. One of the main aims of the food industry is to manufacture products with good sensory acceptance.

Stem Cell Markers (Cytokeratin 17 and Cytokeratin 19) in Scarring and Nonscarring Alopecia.

Background: Alopecia is one of the most important hair follicle (HF) disorders, which is divided into scarring (cicatricial) and nonscarring (noncicatricial) types.

Objective: The aim of this study is to investigate the expression of stem cell (SC) markers such as cytokeratin (CK) 17 and CK19 in scarring and nonscarring alopecia.

Materials And Methods: Thirty patients with scalp alopecia (15 with scarring alopecia and 15 without) together with ten healthy volunteers were included in this study.

β-catenin and SKP2 proteins as predictors of grade and stage of non-muscle invasive urothelial bladder carcinoma.

Background: To evaluate the expression of beta-catenin (β-catenin) and SKP2 proteins in superficial bladder cancer cases and their correlation with tumor grade and stage.

Methods: After institutional review board approval, we retrospectively evaluated the expression of β-catenin and SKP2 proteins in tissue specimens from patients with non-muscle invasive bladder cancer (NMIBC) and compared their results with a cohort of chronic nonspecific cystitis's. Then we and explored these markers association with tumor grade and stage.

Immunohistochemical expression of perforin in lichen planus lesions.

Background: Lichen planus (LP) is a chronic inflammatory papulosquamous skin disease characterized by epidermal basal cell damage and a particular band-like infiltrate predominantly of T cells in the upper dermis. It is characterized by the formation of colloid bodies representing apoptotic keratinocytes. The apoptotic process mediated by CD8+ cytotoxic T lymphocytes and natural killer cells mainly involves two distinct pathways: the perforin/granzyme pathway and the Fas/FasL pathway.

Perforin expression in plaque psoriasis: an immunohistochemical study.

Psoriasis (PsO) is T-cell-mediated disease resulting from aberrant activation of both innate and adaptive immunity. Perforin is a multi-domain, pore-forming protein. It is located within the cytoplasm of CD 8 cytotoxic T cells (CTLs) and natural killer cells (NK).

Mast cells and angiogenesis in wound healing.

Objective: To investigate the role of mast cells and vascular endothelial growth factor (VEGF) as a mediator of angiogenesis to promote wound healing in surgical and pathological scars.

Study Design: The study was carried out on 40 patients who presented with active scar lesions. They were subdivided into 4 groups.

Isolated oral Kaposi sarcoma in an HIV-negative patient: a case report.

Background: Kaposi sarcoma is a well-known vascular tumor first described by Moriz Kaposi in 1872. Oral involvement is seen as an AIDS-related malignant neoplasm but is rarely described in HIV-negative and non-immunosuppressed individuals.

Case: We report a case of oral Kaposi sarcoma in a 75-year-old, HIV-negative woman.
