Article Synopsis
  • Plants are valuable in medicine due to their low cost, availability, and minimal side effects; certain plant-based compounds can help manage diabetes when combined with nanoparticles (NPs).
  • The study reviewed 16 research papers highlighting the antidiabetic effects of green synthesized nanoparticles (GSNPs) showing significant enzyme inhibition and positive results in lipid profiles among diabetic animal models.
  • Characterization of GSNPs, including their size and surface charge, is crucial for ensuring their effectiveness and stability in biomedical applications, making them promising for future diabetes treatments.

Hemorheology and microcirculation alterations are caused by erythrocyte size and shape (ESS) modifications. People´s diets can alter erythrocyte functions and membrane fluidity by changing cell membrane components. The aim was to identify differences in ESS obtained by scanning electron (SEM) and atomic force microscopy (AFM) in people with prediabetes and type 2 diabetes (T2DM) and assess their relationship with dietary patterns.

Purpose: Exosomes are extracellular membrane vesicles. Their content directly reflects the metabolic state of the cells from which they originate and play an important role in cellular functions and pathological states, for example, cancer. The aim was to establish the effect of exosomes from patients diagnosed with CIN1 (grade one cervical intraepithelial neoplasia) on the viability of HeLa cells in culture.

Background: People living with diabetes need constant glucose monitoring to avoid health complications. However, they do not monitor their glucose levels as often as recommended, probably because glucose measurement devices can be painful, costly, need testing strips or sensors, require lancing the finger or inserting a sensor with risk of infection, and can be inaccurate or have failures. Therefore, developing new alternatives for noninvasive glucose measurements that overcome these disadvantages is necessary, being Raman spectroscopy (RS) a solution.

Aims: To evaluate the in vitro effect of different glucose concentrations and the time series in erythrocyte cell viability and morphology parameters.

Methods: Different glucose concentrations were assessed, from a normal physiological glucose concentration (5 mM) to a diabetes scenario (100 mM). Cell viability was obtained by the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay.

Orthodontic brackets release ions that can be reabsorbed in the oral mucosa, potentially causing complications, including cytotoxic effects and mutagenic alterations. The aim was to evaluate the genotoxicity induced by orthodontic appliance alloys in cultures of human gingival fibroblasts by comet assay. Eluates were obtained from the following brackets alloys: EconoLine (SS: stainless steel), MiniMirage (Ni-Ti: nickel-titanium), Nu-Edge (Co-Cr: cobalt-chromium), In-Vu (PC-polycrystals (PC) aluminum oxide), and Monocrystal IZE (monocrystalline (MC) aluminum oxide).

The study aim was to assess the application of atomic force microscopy (AFM) to evaluate erythrocyte morphology in early stages of type 2 diabetes mellitus, and the association with biochemical, anthropometric, diet, and physical activity indicators. This was a pilot cross-sectional study with four groups: healthy individuals, people with prediabetes (PDG), metabolic syndrome (MSG), and diabetes mellitus group (DMG). Blood samples were obtained to assess the erythrocyte morphology and biochemical parameters.

The purpose of this statement is to debate the recommendations of the American Heart Association (AHA) for the prevention of infective endocarditis through an antibiotic prophylaxis protocol and its relation with bacterial resistance to antibiotics. Since dental infections involve biofilms that include several bacterial species (Gram-negative and Gram-positive), it is essential, from the dental point of view, to consider the frequency, magnitude, and duration of bacteremia associated with active dental infections before applying antibiotic prophylaxis. The actual guidelines for antibiotic prophylaxis should be revised according to recent evidence of bacterial resistance.

Background: The main microorganism associated with the failure of endodontic treatments is . Although several endodontic therapeutics have demonstrated antimicrobial activity against , the antimicrobial effectiveness of chitosan (CsNPs) and silver nanoparticles (AgNPs) included into conventional endodontic sealers for endodontic therapies is still unclear.

Aim: The objective of this study was to evaluate the antibacterial activity increment (AAI) of endodontic sealers containing CsNPs and AgNPs as well as some chemical components against by direct contact assays.

Aim: To evaluate the erythrocyte morphology in people with prediabetes, T2DM and healthy subjects in a Mexican population and its association with biochemical parameters.

Methods: Cross-sectional study consisted of three groups: healthy (HG), people with prediabetes (PG) and with T2DM (DMG). A blood sample was obtained from all participants to assess the erythrocyte morphology, and levels of HbA1c, glucose and lipid profile.

Article Synopsis
  • - This study evaluated 2,216 newborns to identify oral abnormalities and their links to prenatal and perinatal factors.
  • - Most common oral findings included Bohn's nodules, Epstein's pearls, and dental lamina cysts, with maternal folic acid consumption showing a significant positive association with these conditions.
  • - Preterm births were linked to a lower prevalence of Bohn's nodules, indicating that maternal nutrition, specifically folic acid and iron intake, plays a critical role in newborn oral health.

Article Synopsis
  • The study aimed to compare dental health issues, including caries and oral conditions, among children with different types of Cerebral Palsy (CP).
  • Out of 120 participants, spastic CP was the most common type, and those with mixed CP had higher levels of dental caries and treatment needs compared to other types.
  • Overall, dental caries, oral habits, and malocclusions were identified as the primary concerns for the oral health of individuals with CP.

Objective: To determine and identify antibiotic-resistant bacteria (ARB) of oral streptococci from active dental infections in adults and its association with age and gender.

Material And Methods: This cross-sectional study included 59 subjects from 18 to 62 years old. Ninety-eighth samples obtained from the subjects were cultivated in agar plates containing antibiotics amoxicillin/clavulanic acid (A-CA), clindamycin, and moxifloxacin (concentrations of 16, 32 or 64 µg/ml).

Objective: While different virulence factors have been reported of Aggregatibacter actinomycetemcomitans (Aa), there is little information about the stimulatory effect of its DNA. The main purpose of this study was to assess the inflammatory response of human gingival fibroblasts (HGFs) stimulated with A. actinomycetemcomitans DNA.
