Background: Recent studies have shown that vitamin D has an essential role in the reproductive system. In this study, we aimed to investigate the effect of vitamin D levels in patients undergoing ovulation induction (OI), and subsequent intrauterine insemination (IUI) procedure.
Materials And Methods: One hundred and four infertile and one hundred and three fertile women were recruited in this cross-sectional study which was conducted in a tertiary level maternity hospital. Infertile patients were divided into pregnant and non-pregnant subgroups after treatment. Individual characteristics and 25-hydroxyvitamin D [25 (OH) D] levels were compared between the groups.
Results: The vast majority of our study population consisted of women who had vitamin D deficiency (96.6%). There was no statistically significant difference between infertile and fertile groups in terms of serum 25 (OH) D levels (P=0.512). Similarly, no significant difference was observed between the pregnant and non-pregnant subgroups of infertile patients regarding 25 (OH) D levels (P=0.267).
Conclusion: There is no association between female infertility and serum vitamin D levels. Vitamin D does not predict pregnancy in infertile women undergoing OI with IUI. Further research which will provide a comparison between much more women who have deficient and sufficient 25 (OH) D levels is warranted.

Thiamin, an essential micronutrient, is a cofactor for enzymes involved in the central carbon metabolism and amino acids pathways. Despite efforts to enhance thiamin content in rice by incorporating thiamin biosynthetic genes, increasing thiamin content in endosperm remains challenging, possibly due to a lack of thiamin stability and/or a local sink. The introduction of storage proteins has been successful in biofortification strategies and similar efforts targeting thiamin led to a 3-4-fold increase in white rice.

Objective: This study aims to investigate the prevalence of vitamin D deficiency among healthy young medical and dental students at Kuwait University.
Methods: This cross-sectional study included a total of 201 medical and dental students (male = 99; female = 102) at Kuwait University. Blood samples were collected to assess 25-hydroxyvitamin D (25(OH)D) by electrochemiluminescence (ECL) immunoassay, and a questionnaire was distributed to address related qualitative data.
The Protective Effects of Citrulline on Testicular Injury Induced by Torsion and Detorsion in Adult Male Rats: An Experimental Study.

Background: Testicular torsion is a critical urological emergency that can lead to testicular ischemia and significant tissue damage. Citrulline, a supplement known for enhancing cellular metabolism and mitigating oxidative stress and inflammation, has been explored for its protective effects against testicular injury resulting from torsion and detorsion in rat models.
Methods: This study involved 42 Wistar rats, divided into six groups: Sham, torsion/detorsion (T/D), and four groups receiving varying doses of Citrulline (300, 600, 900 ) and vitamin E (20 ).
