Vitamins A and D are essential nutrients that play important roles in growth and development. Preterm and low birth weight infants have low levels of these nutrients and are at risk for developing detrimental health consequences associated with vitamin A and vitamin D deficiencies. Preliminary data suggest that vitamin A and D supplementation is needed to prevent deficiency. More work is needed to define optimal doses, timing, and modes of administration to ensure that an adequate supply of these vitamins is available to meet the critical needs during pregnancy and in high-risk neonates.

Despite the EU legislation regulating the circulation of dietary and food supplements within the internal market, the system of state control requires improvement. For instance, due to existing regulatory gaps, certain pharmaceutical entities commit violations of regulatory requirements, such as failing to register medicinal products and selling them under the guise of dietary and/or food supplements. Conversely, physicians may recommend ordinary dietary and food supplements to patients as if they were medicinal products.

Carrier-free nanomedicines exhibited significant potential in elevating drug efficacy and safety for tumor management, yet their self assembly typically relied on chemical modifications of drugs or the incorporation of surfactants, thereby compromising the drug's inherent pharmacological activity. To address this challenge, we proposed a triethylamine (TEA)-mediated protonation-deprotonation strategy that enabled the adjustable-proportion self assembly of dual drugs without chemical modification, achieving nearly 100% drug loading capacity. Molecular dynamic simulations, supported by experiment evidence, elucidated the underlying self-assembly mechanism.

Retinopathy with Vitamin E Deficiency (RVED) is a familial disease in the English Cocker Spaniel (ECS) dog breed. Ophthalmic abnormalities observed in RVED-affected ECS include lipofuscin granule deposition within the tapetal fundus and subsequent retinal degeneration resulting in visual deficits. Affected dogs may also exhibit neurological signs that include ataxia and hindlimb proprioceptive deficit.

Objective: To evaluate the effects of a combination of carnitines, L-arginine, L-cysteine and myo-inositol on metabolic and reproductive parameters in PCOS overweight/obese patients.
Methods: This was a retrospective study analyzing information of a group of PCOS ( = 25) overweight/obesity patients, not requiring hormonal treatment, selected from the database of the ambulatory clinic of the Gynecological Endocrinology Center at the University of Modena and Reggio Emilia, Modena, Italy. The hormonal profile, routine exams and insulin and C-peptide response to oral glucose tolerance test (OGTT) were evaluated before and after 12 weeks of a daily oral complementary treatment with L-carnitine (500 mg), acetyl-L-carnitine (250 mg), L-arginine (500 mg), L-cysteine (100 mg) and myo-inositol (1 gr).
