Journal ArticleDOI
Skin delivery of epigallocatechin-3-gallate (EGCG) and hyaluronic acid loaded nano-transfersomes for antioxidant and anti-aging effects in UV radiation induced skin damage.
Kiran Avadhani,Jyothsna Manikkath,Mradul Tiwari,Misra Chandrasekhar,Ashok Godavarthi,Shimoga M. Vidya,Raghu Chandrashekar Hariharapura,Guruprasad Kalthur,Nayanabhirama Udupa,Srinivas Mutalik +9 more
TL;DR: The optimized transfersomes were found to increase the cell viability and reduce the lipid peroxidation, intracellular ROS and expression of MMPs in HaCaT cells, which underline the potential application of the developed transfersomes in sunscreen cream/lotions for improvement of UV radiation-protection along with deriving antioxidant and anti-aging effects.
Journal ArticleDOI
Poor sperm quality and advancing age are associated with increased sperm DNA damage in infertile men.
J Varshini,BS Srinag,Guruprasad Kalthur,Hanumanthappa Krishnamurthy,Pratap Kumar,Satish Rao,Satish Kumar Adiga +6 more
TL;DR: Age‐related increase in sperm DNA damage and association of the same with varicocele and alcohol consumption are demonstrated, and poor sperm characteristics in the ejaculate are associated with increased sperm DNADamage.
Journal ArticleDOI
Vitamin E Supplementation in Semen-Freezing Medium Improves the Motility and Protects Sperm from Freeze-Thaw–Induced DNA Damage
Guruprasad Kalthur,Sujith Raj,Aparna Thiyagarajan,Sangeetha Kumar,Pratap Kumar,Satish Kumar Adiga +5 more
TL;DR: Results of this study indicate that supplementation of vitamin E (5 mM) significantly improves the post-thaw motility and DNA integrity in normozoospermic and asthenozoos permic semen samples.
Journal ArticleDOI
Development and evaluation of sunscreen creams containing morin-encapsulated nanoparticles for enhanced UV radiation protection and antioxidant activity.
Pallavi K. Shetty,Venkatesh Venuvanka,Hitesh Vitthal Jagani,Gejjalagere Honnappa Chethan,Virendra S Ligade,Prashant B Musmade,Usha Y. Nayak,Meka Sreenivasa Reddy,Guruprasad Kalthur,Nayanabhirama Udupa,Chamallamudi Mallikarjuna Rao,Srinivas Mutalik +11 more
TL;DR: In vitro and in vivo skin permeation studies of sunscreen creams containing morin NPs indicated excellent deposition of morin within the skin, which confirmed outstanding UV radiation protection as well as antioxidant properties.
Journal ArticleDOI
Effect of cryopreservation on sperm DNA integrity in patients with teratospermia
TL;DR: The susceptibility of morphologically abnormal sperm to DNA damage/chromatin modification during the freeze-thaw process is significantly higher than that of sperm with normal morphology.
