β-nerve growth factor (βNGF) plays a crucial role in reproductive physiology and sperm quality. Enzymatic activity of seminal plasma and vaginal fluids reduces available βNGF and it has been demonstrated that chitosan microspheres could protect rrβNGF from degradation. This study examined the effects of microencapsulated rrbNGF with chitosan on rabbit sperm viability, motility and capacitation status.

- In intensive farm settings, rabbit does experience overlapping lactation and gestation, leading to increased energy demands and oxidative stress.
- This study tested the effects of daily quercetin (QUR) supplementation on the antioxidant status of 24 rabbit does, both young and adult, over 8 weeks.
- Results showed QUR did not significantly change the antioxidant levels or health status of the rabbits, as measured by plasma glutathione, serum superoxide dismutase, and malondialdehyde.
Tracking Macular Sensitivity and Inner Retinal Thickness in Long-Term Type 1 Diabetes: A Five-Year Prospective Examination in Patients without Diabetic Retinopathy.

September 2024
Article Synopsis
- The study compares macular sensitivity and retinal thickness in long-term type 1 diabetes mellitus (DM1) patients without diabetic retinopathy (DR) over a 5-year period.
- Thirty-two eyes from DM1 patients were examined using microperimetry and spectral domain optical coherence tomography (SD-OCT), revealing significantly worse best corrected visual acuity (BCVA) in 2023 compared to 2018.
- Although macular sensitivity didn't change significantly, notable differences in macular integrity and retinal thickness, especially in the inner retinal layers, suggest that long-term DM1 patients can experience undetected retinal changes and functional decline despite not exhibiting DR symptoms.
To study retinal and choriocapillaris (CC) alterations using optical coherence tomography angiography (OCTA) in long-term type 1 diabetic (DM1) patients without diabetic retinopathy (DR). Seventy-eight eyes from 78 well-controlled DM1 patients diagnosed at least 15 years prior and 130 eyes of 130 healthy subjects were included in a cross-sectional descriptive study. Six eyes were excluded from the DM1 group.

Methods: Prospective study involving 92 eyes divided into two groups. The diabetic group included 46 eyes of 23 patients with type 1 diabetes (T1DM); the control group included 23 age-matched healthy subjects.
