Physicochemical and aromatic properties of iron-enriched tomato paste during storage.

In this study, tomato paste was fortified with iron compounds at 25, 50, and 75 ppm concentrations. The effect of adding these micronutrient iron concentrations on the paste's physical, mechanical, aromatic, and chemical properties was evaluated every 15 days over a 60-day, storage period. The results indicated a gradual decrease in pH, total soluble solids (TSS), and taste index, alongside an increase in total acidity (TA) for all treatments throughout the storage period.

Evaluation the effects of temperature and packaging conditions on the quality of button mushroom during storage using e-nose system.

In this study, the effects of different packaging conditions on the quality of button mushrooms and some its chemical properties (pH and TSS) using an e-nose system equipped with ten sensors have been investigated. The button mushrooms were packaged using two types of films in two atmospheric modes. They were stored at 25 and 4 °C for ten days.

Investigating the effect of chitosan, nanopackaging, and modified atmosphere packaging on physical, chemical, and mechanical properties of button mushroom during storage.

This study investigated the effect of chitosan coating, nanopackaging, and modified atmosphere packaging (MAP) to increase the shelf life and improve the quality of the white button mushroom. Uncoated and coated button mushrooms were stacked in three types of packages (normal, nano, and nano + MAP). The atmosphere inside the nano + MAP packages contained 10% oxygen and 10% carbon dioxide.

Clinical Characteristic of the HIV/AIDS Patients with Cryptosporidiosis Referring to Behavioral Diseases Consultation Center, Imam Khomeini Hospital, Tehran in 2013.

Background: Cryptosporidium is known as an opportunist disease-causing agent in man in recent decades. It causes diarrhea and intestinal disorders in the immune deficit and immune competent individuals. This study was aimed to investigate the clinical characteristics of HIV/AIDS patients with cryptosporidiosis infection.

Emerging Intestinal Microsporidia Infection in HIV(+)/AIDS Patients in Iran: Microscopic and Molecular Detection.

Background: Species of Microsporidia have been known as opportunistic obligate intracellular parasites particularly in immunocompromised patients. Enterocytozoon bieneusi is one of most prevalent intestinal microsporida parasites in HIV(+)/AIDS patients. In this study, intestinal microsporidia infection was determined in HIV(+)/AIDS patients using microscopic and molecular methods.
