Effect of pasteurization and of freezing and thawing human milk on its triglyceride content.

بررسی اثر هیالورونان روی میزان لقاح اسپرم‌های موش سوری قبل از انجماد و پس از ذوب

Background: Freezing and thawing induce a number of insults to the sperm cells, such as low motility and low fertilization capability. For evaluation of hyaluronan (HA) supplementation on sperm characteristics, we investigated the effect of hyaluronan (HA) on mouse sperm before freezing and after thawing. Methods: For this purpose we removed cauda epididimes from 24 male mice with aseptic meth...

Freezing and thawing effects on fat, protein, and lactose levels of human natural milk administered by gavage and continuous infusion.

OBJECTIVES to analyze the changes in human milk macronutrients: fat, protein, and lactose in natural human milk (raw), frozen and thawed, after administration simulation by gavage and continuous infusion. METHOD an experimental study was performed with 34 human milk samples. The infrared spectrophotometry using the infrared analysis equipment MilkoScan Minor® (Foss, Denmark) equipment was use...

Effects of multiple freezing and refrigerator thawing cycles on the quality changes of sea bass (Dicentrarchus labrax)

The freezing-thawing effect on the meat quality of whole, gutted and fillets of sea bass (Dicentrarchus labrax) were investigated. It was aimed to investigate the changes in the meat quality of whole, gutted and fillets of sea bass in multiple frozen (-18±2ºC) and thawed cycles in refrigerated conditions (4±2°C). The meat quality assessment of the sea bass groups (whole, gutted and fillets) sub...

Validation of Correction Algorithms for Near-IR Analysis of Human Milk in an Independent Sample Set—Effect of Pasteurization

Commercial infrared (IR) milk analyzers are being increasingly used in research settings for the macronutrient measurement of breast milk (BM) prior to its target fortification. These devices, however, may not provide reliable measurement if not properly calibrated. In the current study, we tested a correction algorithm for a Near-IR milk analyzer (Unity SpectraStar, Brookfield, CT, USA) for fa...
