Association of vitamin D receptor gene polymorphisms, metabolic features and susceptibility to polycystic ovary syndrome: a preliminary study.

Research Question: Are the combined genotypes and haplotypes of vitamin D receptor (VDR) gene polymorphisms (FokI, ApaI and TaqI) associated with susceptibility to polycystic ovary syndrome (PCOS) and metabolic features of the disease?

Design: This case-control study included 46 women with PCOS and 48 controls. Genotypes of the VDR gene were determined using the polymerase chain reaction-restriction fragment length polymorphism method. Waist circumference, and parameters of lipid and glucose metabolism were evaluated in all women.

The impact of vitamin D3 administration and of high fat diet on oxidative stress and inflammation in experimentally induced polycystic ovary syndrome.

Background: Polycystic ovary syndrome (PCOS) is commonly associated with obesity and may be exacerbated by the lack of vitamin D3.

Aim: The study aimed to investigate the effects of vitamin D3 administration in female rats with PCOS and prolonged high fat diet (HFD).

Methods: Forty-four female Wistar rats, 180-200 g, 10 weeks old, were randomly allocated into 2 groups (n=22) that received a single dose intramuscular injection of: sesame oil (group I), or estradiol valerate (5 mg) in sesame oil (group II).

Circular RNA-Mediated Regulation of Oral Tissue-Derived Stem Cell Differentiation: Implications for Oral Medicine and Orthodontic Applications.

Circular RNAs (circRNAs) are a novel class of endogenous non-coding RNAs (ncRNAs) which unlike linear RNAs, have a covalently closed continuous loop structure. circRNAs are found abundantly in human cells and their biology is complex. They feature unique expression to different types of cells, tissues, and developmental stages.

Polymorphisms of Vitamin D Receptor and the Effect on Metabolic and Endocrine Abnormalities in Polycystic Ovary Syndrome: A Review.

Polycystic ovary syndrome (PCOS) is one of the most prevalent endocrine disorder in women of reproductive age. Vitamin D and its receptor are thought to play an important role in PCOS susceptibility, although the impact of vitamin D receptor (VDR) polymorphisms on the hormonal and metabolic profile is still controversial. A literature search in PubMed and Embase was performed up to September 2020 for case-control studies in women suffering from PCOS, with outcome related to VDR polymorphisms effect on metabolic/endocrine disturbances.

An Orthodontic Approach for Garre's Sclerosing Osteomyelitis of the Mandible.

The nonsuppurative osteomyelitis of the mandible is a rare condition that can occur in children due to low-grade inflammatory processes, dental cavities, periodontal lesions as well as the eruption process of the teeth. We submit a case report involving the orthodontic management of a 9-year-old female patient who presented in our service in the mixed dentition period with diagnosed Garre's sclerosing osteomyelitis of the entire mandibular body. After a full work-up, the following symptoms and signs were noted: bilateral temporomandibular joint (TMJ) pain, loss of the leeway space, anterior open bite, distalization of the secondary maxillary right canine, nail biting and tongue thrust.
