The Associations of Dental and Periodontal Lesions with the Microvascular Complications in Patients with Type 2 Diabetes Mellitus: A Case-Control Study.

Background: Diabetes mellitus is closely related to periodontal disease and dental lesions, disorders which through dental infection and metabolic imbalance become negatively potentiated and cause a vicious circle that is almost impossible to break. The aim of this research was to study if the severity of dental and periodontal lesions is related to the presence of microvascular complications and glycemic control in patients with type 2 diabetes mellitus (T2DM).

Methods: In total, 112 subjects with T2DM that underwent a dental evaluation were enrolled in this case-control study.

The Interactions Between Diet and Gut Microbiota in Preventing Gestational Diabetes Mellitus: A Narrative Review.

Recent studies have revealed that dysbiosis, defined as alterations in gut microbiota, plays an important role in the development and the progression of many non-communicable diseases, including metabolic disorders, such as type 2 diabetes mellitus and gestational diabetes mellitus (GDM). The high frequency of GDM makes this disorder an important public health issue, which needs to be addressed in order to reduce both the maternal and fetal complications that are frequently associated with this disease. The studies regarding the connections between gut dysbiosis and GDM are still in their early days, with new research continuously emerging.

Back to Roots: Dysbiosis, Obesity, Metabolic Syndrome, Type 2 Diabetes Mellitus, and Obstructive Sleep Apnea-Is There an Objective Connection? A Narrative Review.

In recent decades, it has become clear that the gut is more than just a digestive organ; it also functions as an immune organ with regulatory capabilities and acts as a "second brain" that influences brain function due to the presence and regulatory roles of the gut microbiota (GM). The GM is a crucial component of its host and significantly impacts human health. Dysbiosis, or microbial imbalance, has been closely linked to various diseases, including gastrointestinal, neurological, psychiatric, and metabolic disorders.

Induction of early growth response protein-1 gene expression in the rat ovary in response to an ovulatory dose of human chorionic gonadotropin.

Granulosa cells in a mature ovarian follicle have an abundance of LH/hCG receptors that respond rapidly to an ovulatory surge in gonadotropins. Within minutes, membrane signal transduction sets in motion metabolic changes that lead to follicular rupture. This study provides evidence that the initial ovarian response to such an ovulatory stimulus includes induction of the immediate-early transcription factor gene for early growth response protein-1 (Egr-1).

7- and 10-substituted camptothecins: dependence of topoisomerase I-DNA cleavable complex formation and stability on the 7- and 10-substituents.

7-Alkyl, 7-alkyl-10-hydroxy, 7-alkyl-10-methoxy, and 7-alkyl-10, 11-methylenedioxy analogs of camptothecin have been synthesized and evaluated for their ability to trap human DNA topoisomerase I in cleavable complexes. The 7-alkyl chain lengths varied linearly from methyl to butyl. The concentration required to produce cleavable complexes with purified topoisomerase I in 50% of the plasmid DNA (EC(50)) was reduced by 1 order of magnitude by the introduction of a 10-methoxy or 7-alkyl group compared with camptothecin.

Characterization of ovarian carbonyl reductase gene expression during ovulation in the gonadotropin-primed immature Rat.

In this differential-display polymerase chain reaction-based study, four different primer sets generated cDNA fragments of ovarian carbonyl reductase genes that were uniquely expressed during the ovulatory process in eCG-primed immature rats. The temporal pattern of expression of this aldo-keto reductase gene was delineated by extracting ovarian RNA at 0, 2, 4, 8, 12, and 24 h after induction of ovulation via injection of the primed animals with hCG. The results showed that at least four homologous forms of this gene were transcribed during ovulation.

Water soluble 20(S)-glycinate esters of 10,11-methylenedioxycamptothecins are highly active against human breast cancer xenografts.

Water-soluble 20(S)-glycinate esters of two highly potent 10,11-methylenedioxy analogues of camptothecin (CPT) have been synthesized and evaluated for their ability to eradicate human breast cancer tumor xenografts. The glycinate ester moiety increases the water solubility of the 10,11-methylenedioxy analogues 4-16-fold. However, in contrast to CPT-11, a water-soluble CPT analogue that was recently approved for second line treatment of colorectal cancer, the 20(S)-glycinate esters do not require carboxylesterase for conversion to their active forms.

Actinomycin D binds to metastable hairpins in single-stranded DNA.

We have examined the role of DNA composition in the binding of actinomycin D to single-stranded DNA. By using the fluorescent analogue 7-aminoactinomycin D, we were able to monitor binding of the drug to ssDNA with single base changes distant from the 5'-TAGT-3' site previously determined to be a high-affinity site for actinomycin D binding (Wadkins et al.
