Shelf-stable cranberry juice precipitate has not been well characterized. Here, we describe using H-C heteronuclear single quantum coherence-nuclear magnetic resonance (HSQC-NMR) spectroscopy for cranberry juice analysis, focusing on proanthocyanidins and the precipitate. HSQC-NMR cross-peaks from juices were categorized as aliphatic, olefinic, aromatic, carbohydrate backbone, or anomeric signals. An average cranberry juice precipitate had significantly more aromatic and significantly less carbohydrate backbone signals than an average supernatant. The precipitate was a collection of biomolecules held together by a mix of weak and strong intermolecular forces. Proanthocyanidin signals from precipitates of juices showed 22 ± 2 to 29.9 ± 0.7% A-type interflavan linkages and 34 ± 2 to 48 ± 3% of flavan-3-ol units with trans stereochemistry between the C2 and C3 positions. Based on this work, H-C HSQC-NMR is useful to analyze cranberry juice and reveals the complex chemical nature of components in the soluble and insoluble phases.

This case report describes an elderly man with a history of recurrent urinary tract infections and obstructive pyelonephritis with struvite stones caused by Proteus mirabilis. Despite appropriate antibiotic treatment, the stones increased in size, necessitating alternative therapy. This case highlights the use of ascorbic acid to lower the urine pH, which contributes to the dissolution of struvite stones.

Background: The present study evaluated the effects of cranberry juice enriched with omega-3 on inflammatory, oxidative stress, and periodontal status in diabetic patients with periodontal disease.
Methods: Forty-one patients with diabetes (35‒67 years old) and periodontal disease were assigned to four groups: C: control (n=12), I1: omega-3 (n=10, 1 g), I2: cranberry juice (n=9, 200 mL), and I3: cranberry juice enriched with omega-3 (n=10, 200 mL, containing 1 g of omega-3) twice daily for 8 weeks. Serum and salivary total antioxidant capacity (TAC), malondialdehyde (MDA), serum uric acid, tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), clinical attachment loss (CAL), pocket depth (PD), bleeding on probing (BOP), and plaque index were evaluated in all the subjects before and after the intervention.

The well-established calcineurin inhibitor, tacrolimus, as an immunosuppressive agent, is widely prescribed after organ transplantation. Cytochrome P450 (CYP 450) isoforms are responsible for the metabolism of many features associated with food parameters like phytochemicals, juices, and fruits. This review article summarizes the findings of previous studies to help predict the efficacy or side effects of tacrolimus in the presence of food variables.

Aim: This study evaluated effects of various solutions on color stability and surface hardness of a nanohybrid dental composite in simulated oral environments.
Materials And Methods: Sixty-four composite disks were fabricated and randomly allocated into eight groups ( = 8 per group): Artificial saliva (AS), Biotene (B), passion fruit juice (PFJ), orange juice (OJ), Sprite (S), Coca-Cola (CO), apple cider vinegar (ACV), and cranberry juice (CJ). Specimens were immersed in respective solutions at 37°C for 28 days.
