Comparison of an artificial, whole-blood membrane feeding procedure was performed by feeding Aedes aegypti (Liverpool strain) on the blood of patients infected with Wuchereria bancrofti microfilariae with the use of 3 types of membranes produced from chicken and mouse skin and swine intestine. Direct feeding of Ae. aegypti on the skin of infected human patients served as control. For all 3 types of membranes, mosquito survival, infection, and number of infective-stage larvae per mosquito did not differ significantly from the control. However, the blood feeding response between swine intestine layer (32%) compared to chicken skin (75.3%), mouse skin (70%), and direct feeding (84%) differed significantly. The response in direct feeding method was significantly higher than those in all membranes tested (F = 18.89; df = 3; P < 0.05) Chicken skin preparation was shown to be the preferred membrane for blood feeding Ae. aegypti and experimental infection with W. bancrofti.

We aimed to evaluate the effects of prepartum supplementation of different I sources (Ascophyllum nodosum [ASCO] meal and ethylenediamine dihydroiodide [EDDI]) on colostrum yield of cows, and blood concentrations of glucose, BHB, and thyroid hormones and growth of dairy calves. Forty multiparous Holstein cows were blocked by lactation number and expected calving date and assigned to 1 of 4 treatments 28 d before parturition: (1) EDDI supplemented (11 mg/d) to a basal diet to meet the NRC (2001) I concentration of 0.5 mg of I/kg of DMI (control = CON [0 g/d of ASCO meal]; actual I concentration = 0.

A 7-week-old infant with a 1-week history of a SARS-CoV2 respiratory infection presented with tachypnea. Cardiomegaly was noted on chest roentgenogram. Echocardiogram showed a large pericardial effusion, with tamponade physiology and a large pericardial mass.

The effects of social isolation (SI) during middle age remain unclear, so we tested the hypothesis that SI would lead to an increase in impulsive choice (IC), anxiety-like behavior, and metabolic dysfunction in middle-aged rats. Male and female rats were housed individually or in groups of four with same-sex housing mates at 11 months of age. Two months later, IC behavior was assessed using a delay-discounting task and anxiety-like behavior through a novelty-suppressed feeding (NSF) task.

Background: The study of women exposures and child outcomes occurring in the first 1,000 days of life since conception enhances understanding of the relationships between environmental factors, epigenetic changes, and disease development, extending beyond childhood and spanning the entire lifespan. Generation Gemelli is a recently launched case-control study that enrolls mother-newborns pairs in one of the largest university hospitals in Italy, in order to examine the association between maternal environmental exposures and intrauterine growth restriction (IUGR) and the risk of premature birth. The study will also evaluate the association of maternal exposures and the health and growth of infants and children up to 24 months of age.
