Background: Oxidative stress and enhanced apoptosis may be involved in the induction of embryonic dysmorphogenesis in diabetic pregnancy. Administration of folic acid or vitamin E diminishes embryonic dysmorphogenesis. We aimed to evaluate the effect of combined treatment with folic acid and vitamin E on the disturbed development in embryos of diabetic rats.
Methods: Pregnant nondiabetic and diabetic rats were treated with daily injections of 15 mg/kg folic acid or with 5% vitamin E in the diet. A third group received combined treatment. Day 10 and day 11 embryos were evaluated for development and apoptotic profile.
Results: We found increased malformations, resorptions, and profound growth retardation in embryos of diabetic rats compared to control embryos. Vitamin E or folic acid alone, or the 2 compounds combined, normalized embryonic demise. Maternal diabetes caused decreased nuclear factor-kappaB (NF-kappaB) activity and B-cell lymphoma 2 (Bcl-2) protein level, and increased Bcl-2-associated x proteins (Bax) in embryos. Supplementation of vitamin E alone normalized the Bax protein level in a diabetic environment. Administration of folic acid to diabetic rats increased NF-kappaB activity and Bcl-2 protein level. Combined treatment normalized Bcl-2 and Bax protein level in a diabetic environment.
Conclusions: Combined supplementation of folic acid and vitamin E to pregnant diabetic rats diminished diabetes-induced malformations and resorptions, concomitant with normalization of apoptotic protein levels. No treatment completely abolished the embryonic demise; therefore, other mechanisms than oxidative stress and apoptosis are likely to be involved in diabetic embryopathy.

The integration of photothermal therapy (PTT) and gas therapy (GT) on a nanoplatform shows great potential in cancer treatment. In this paper, a tumor-targeted near-infrared/ultraviolet (NIR/UV) triggered PTT/GT synergistic therapeutic nanoplatform, PB-CD-PLL(NF)-FA, was designed based on Prussian blue (PB) nanoparticles, 5-chloro-2-nitrobenzotrifluoro (NF)-grafted polylysine (PLL(NF)), and folic acid (FA). PB serves as a core to load PLL(NF) through host-guest interaction and can further modify FA.

Background: The long-term follow-up studies investigating the risk of anemia and iron deficiency following bariatric procedures are scarce. This study aimed to determine the influence of body weight reduction and type of bariatric surgery on iron metabolism parameters.
Methods: We included 138 consecutive patients who underwent bariatric surgery (120 underwent sleeve gastrectomy and 18 underwent other types of bariatric surgery) between 2010 and 2016.

Background/objectives: Chronic gut dysbiosis due to a high-fat diet (HFD) instigates cardiac remodeling and heart failure with preserved ejection fraction (HFpEF), in particular, kidney/volume-dependent HFpEF. Studies report that although mitochondrial ATP citrate lyase (ACLY) supports cardiac function, it decreases more in human HFpEF than HFrEF. Interestingly, ACLY synthesizes lipids and creates hyperlipidemia.

Resveratrol can beneficially affect growth and follicle development and lead to improved sperm function parameters in pre-clinical studies, while information from clinical studies is still inconclusive. This study aims to evaluate the biological and clinical impact of a resveratrol-based multivitamin supplement on level II assisted reproduction cycles (IVF and intracytoplasmic sperm injection [ICSI]). A retrospective, case-control study, involving 70 infertile couples undergoing IVF/ICSI cycles, was conducted at the Assisted Reproductive Center, Obstetrics and Gynecology Unit-Villa Sofia-Cervello Hospital in Palermo.

Background: This study aimed to describe Sickle Cell Disease (SCD) phenotypes, sociodemographic characteristics, healthcare, and clinical outcomes of patients with SCD attending Mnazi Mmoja Hospital (MMH) in Zanzibar.
Methods: Individuals who visited MMH between September 2021 and December 2022 and were known or suspected to have SCD were enrolled in the clinic. Sociodemographic characteristics and clinical features were documented, and laboratory tests were performed.
