RESUMEN
Ankyloglossia, which is a congenital condition also referred to as tongue-tie, is described as a small lingual frenum that restricts tongue movement and its function. The main purpose of the frenum is to restrict the movement of the cheek, lip muscles, and tongue throughout the development of fetuses and maintain equilibrium between the developing bones, lip musculature, and tongue. The constriction of the buccal musculature counteracts the outward pressure that the tongue applies to the teeth. Arch width maintenance requires a state of equilibrium between these two muscle groups. Therefore, altering tongue position might additionally have an impact on a mandible's position. A 20-year-old female patient presented to the Periodontics Department with moderate ankyloglossia (Kotlow Class II). For the correction of the tongue-tie, conventional surgery with sutures was scheduled under local anesthesia. One week, one month, and three months follow-up, the patient demonstrated good healing. There was an improvement in speech clarity and tongue movements.
RESUMEN
The primary objective of this study was to develop a risk-based readmission prediction model using the EMR data available at discharge. This model was then validated with the LACE plus score. The study cohort consisted of about 310,000 hospital admissions of patients with cardiovascular and cerebrovascular conditions. The EMR data of the patients consisted of lab results, vitals, medications, comorbidities, and admit/discharge settings. These data served as the input to an XGBoost model v1.7.6, which was then used to predict the number of days until the next readmission. Our model achieved remarkable results, with a precision score of 0.74 (±0.03), a recall score of 0.75 (±0.02), and an overall accuracy of approximately 82% (±5%). Notably, the model demonstrated a high accuracy rate of 78.39% in identifying the patients readmitted within 30 days and 80.81% accuracy for those with readmissions exceeding six months. The model was able to outperform the LACE plus score; of the people who were readmitted within 30 days, only 47.70 percent had a LACE plus score greater than 70, and, for people with greater than 6 months, only 10.09 percent had a LACE plus score less than 30. Furthermore, our analysis revealed that the patients with a higher comorbidity burden and lower-than-normal hemoglobin levels were associated with increased readmission rates. This study opens new doors to the world of differential patient care, helping both clinical decision makers and healthcare providers make more informed and effective decisions. This model is comparatively more robust and can potentially substitute the LACE plus score in cardiovascular and cerebrovascular settings for predicting the readmission risk.
RESUMEN
Frenum morphology is of pivotal concern while treating patients who desire improved aesthetics and for treating patients with midline diastemas, as it may lead to failure or relapse of orthodontic treatment. Frenum, a thick band of muscle fiber, may present with abnormalities in the shape, size, form, number, and thickness, which may cause gingival recession along with poor oral health. Frenectomy is adopted as the plan of action while treating abnormal frenum cases by resecting the frenum attachment to provide closure of the spacing between the upper anterior teeth, as in the case of midline diastema. Various forms and techniques of frenectomy have been adopted according to the type of frenum attachment and aesthetic concerns of the patients. Amidst the various treatment options available, conventional frenectomy using a scalpel has emerged as a viable solution for treating patients. The surgeons value and praise its exceptional precision and ease of use, and the patients prefer it for its affordability; hence, a functional and aesthetic outcome is achieved via this treatment. This report provides a comprehensive overview of a case of conventional frenectomy with a one-week follow-up.
RESUMEN
Type 2 and type 1 diabetes (T2D, T1D) exhibit sex differences in insulin secretion, the mechanisms of which are unknown. We examined sex differences in human pancreatic islets from 52 donors with and without T2D combining single cell RNA-seq (scRNA-seq), single nucleus assay for transposase-accessible chromatin sequencing (snATAC-seq), hormone secretion, and bioenergetics. In nondiabetic (ND) donors, sex differences in islet cells gene accessibility and expression predominantly involved sex chromosomes. Islets from T2D donors exhibited similar sex differences in sex chromosomes differentially expressed genes (DEGs), but also exhibited sex differences in autosomal genes. Comparing ß cells from T2D vs. ND donors, gene enrichment of female ß cells showed suppression in mitochondrial respiration, while male ß cells exhibited suppressed insulin secretion. Thus, although sex differences in gene accessibility and expression of ND ß cells predominantly affect sex chromosomes, the transition to T2D reveals sex differences in autosomes highlighting mitochondrial failure in females.
RESUMEN
Cytochrome P450 2D6 (CYP2D6) is one of the most important enzymes involved in drug metabolism. Genetic polymorphism can influence drug metabolism by CYP2D6 such that a therapy is seriously affected by under- or overdosing of drugs. However, a general explanation at the atomistic level for poor activity is missing so far. Here we show for the 20 most common single nucleotide polymorphisms (SNPs) of CYP2D6 that poor metabolism is driven by four mechanisms. We found in extensive all-atom molecular dynamics simulations that the rigidity of the I-helix (central helix), distance between central phenylalanines (stabilizing bound substrate), availability of basic residues on the surface of CYP2D6 (binding of cytochrome P450 reductase), and position of arginine 132 (electron transfer to heme) are essential for an extensive function of the enzyme. These results were applied to SNPs with unknown effects, and potential SNPs that may lead to poor drug metabolism were identified. The revealed molecular mechanisms might be important for other drug-metabolizing cytochrome P450 enzymes.

The voltage penalty driving water dissociation (WD) at high current density is a major obstacle in the commercialization of bipolar membrane (BPM) technology for energy devices. Here we show that three materials descriptors, that is, electrical conductivity, microscopic surface area and (nominal) surface-hydroxyl coverage, effectively control the kinetics of WD in BPMs. Using these descriptors and optimizing mass loading, we design new earth-abundant WD catalysts based on nanoparticle SnO2 synthesized at low temperature with high conductivity and hydroxyl coverage. These catalysts exhibit exceptional performance in a BPM electrolyser with low WD overvoltage (ηwd) of 100 ± 20 mV at 1.0 A cm-2. The new catalyst works equivalently well with hydrocarbon proton-exchange layers as it does with fluorocarbon-based Nafion, thus providing pathways to commercializing advanced BPMs for a broad array of electrolysis, fuel-cell and electrodialysis applications.
RESUMEN
This study focuses on the systematic exploration of the emodepside conformations bound to monovalent K+ ion using quantum mechanical density functional theory (DFT) calculations at the M06-2X/6-31+G(d,p) level of theory. Nine conformers of emodepside and their complexes with K+ ion were characterized as stationary points on the potential energy surface. The conformational isomers were examined for their 3D structures, bonding, energetics, and interactions with the cation. A cavitand-like structure (CC) is identified to be the energetically most stable arrangement. To arrive at a better understanding of the K+ ion binding, calculations were initially performed on complexes formed by the K+ and Na+ ions with model ligands (methyl ester and N,N-dimethyl acetamide). Both the natural bond orbital (NBO) method and the block-localized wavefunction (BLW) energy decomposition approach was employed to assess the bonding and energetic contributions stabilizing the ion-bound model complexes. Finally, the solvent effect was evaluated through complete geometry optimizations and energy minimizations for the model ion-ligand complexes and the emodepside-K+ bound complexes using an implicit solvent model mimicking water and DMSO.
RESUMEN
Frenum aberrations in the maxillary and mandibular regions are pivotal concerns, particularly regarding midline diastema and gingival health. The frenum is composed predominantly of collagenous and elastic fibers. There are various frenal attachment anomalies that may result in gingival recession. Amidst treatment options, conventional scalpel frenectomy emerges as a viable solution, showcasing its efficacy in addressing deviant frena. Ultimately, our findings underscore the imperative for personalized interventions to alleviate aesthetic apprehensions and uphold periodontal integrity in adult populations.
RESUMEN
Periodontal disease, a significant worldwide health burden, is characterized by chronic inflammation and destruction of periodontal tissues, including the cementum, periodontal ligament (PDL), alveolar bone, and gingival tissue. Recent research has linked the development and progression of periodontal disease to oxidative stress. This study provides comprehensive explanations of the mechanisms behind oxidative stress in periodontal disease, with a focus on the generation of reactive oxygen species (ROS) and their effects on periodontal tissues. Oxidative stress triggers a number of detrimental reactions, including lipid peroxidation, protein oxidation, and damage to deoxyribonucleic acid (DNA). Alveolar bone resorption, connective tissue degradation, and periodontal inflammation are further conditions exacerbated by these processes. In addition, the delicate balance between antioxidants and oxidants is upset by oxidative stress, which impairs antioxidant defense systems and exacerbates periodontal tissue damage. This review highlights the negative effects of oxidative stress and enhances periodontal health outcomes.
RESUMEN
A lingual frenectomy is a surgical procedure aimed at addressing "tongue-tie" or ankyloglossia, where a strip of tissue restricting tongue movement is removed. Typically, this strip extends from the bottom of the mouth to the underside of the tongue. The procedure, often performed using a diode laser, offers several advantages including simplicity and safety for patients. It can significantly improve speech articulation and eating for individuals with ankyloglossia. This case report highlights the successful treatment of a female patient experiencing speech difficulties with diode laser therapy for tongue-tie.
RESUMEN
Most odontogenic tumors are intraosseous growths. A peripheral odontogenic fibroma presents as a slow-growing and firm swelling on the gingiva. It develops more commonly on the mandibular than the maxillary region. It can be found on either the palatal or lingual and on the labial or buccal surface of the jaw. It usually does not ulcerate. The most common type is a peripheral odontogenic fibroma, which is a benign odontogenic neoplasm of the periodontal soft tissues. In this case report, a 53-year-old male patient with peripheral odontogenic fibroma was treated using a laser.
RESUMEN
Photoacoustic Spectroscopy (PAS) is a potential method for the noninvasive detection of blood glucose. However random blood glucose testing can help to diagnose diabetes at an early stage and is crucial for managing and preventing complications with diabetes. In order to improve the diagnosis, control, and treatment of Diabetes Mellitus, an appropriate approach of noninvasive random blood glucose is required for glucose monitoring. A polynomial kernel-based ridge regression is proposed in this paper to detect random blood glucose accurately using PAS. Additionally, we explored the impact of the biological parameter BMI on the regulation of blood glucose, as it serves as the primary source of energy for the body's cells. The kernel function plays a pivotal role in kernel ridge regression as it enables the algorithm to capture intricate non-linear associations between input and output variables. Using a Pulsed Laser source with a wavelength of 905 nm, a noninvasive portable device has been developed to collect the Photoacoustic (PA) signal from a finger. A collection of 105 individual random blood glucose samples was obtained and their accuracy was assessed using three metrics: Root Mean Square Error (RMSE), Mean Absolute Difference (MAD), and Mean Absolute Relative Difference (MARD). The respective values for these metrics were found to be 10.94 (mg/dl), 10.15 (mg/dl), and 8.86%. The performance of the readings was evaluated through Clarke Error Grid Analysis and Bland Altman Plot, demonstrating that the obtained readings outperformed the previously reported state-of-the-art approaches. To conclude the proposed IoT-based PAS random blood glucose monitoring system using kernel-based ridge regression is reported for the first time with more accuracy.

Biological sex affects the pathogenesis of type 2 and type 1 diabetes (T2D, T1D) including the development of ß cell failure observed more often in males. The mechanisms that drive sex differences in ß cell failure is unknown. Studying sex differences in islet regulation and function represent a unique avenue to understand the sex-specific heterogeneity in ß cell failure in diabetes. Here, we examined sex and race differences in human pancreatic islets from up to 52 donors with and without T2D (including 37 donors from the Human Pancreas Analysis Program [HPAP] dataset) using an orthogonal series of experiments including single cell RNA-seq (scRNA-seq), single nucleus assay for transposase-accessible chromatin sequencing (snATAC-seq), dynamic hormone secretion, and bioenergetics. In cultured islets from nondiabetic (ND) donors, in the absence of the in vivo hormonal environment, sex differences in islet cell type gene accessibility and expression predominantly involved sex chromosomes. Of particular interest were sex differences in the X-linked KDM6A and Y-linked KDM5D chromatin remodelers in female and male islet cells respectively. Islets from T2D donors exhibited similar sex differences in differentially expressed genes (DEGs) from sex chromosomes. However, in contrast to islets from ND donors, islets from T2D donors exhibited major sex differences in DEGs from autosomes. Comparing ß cells from T2D and ND donors revealed that females had more DEGs from autosomes compared to male ß cells. Gene set enrichment analysis of female ß cell DEGs showed a suppression of oxidative phosphorylation and electron transport chain pathways, while male ß cell had suppressed insulin secretion pathways. Thus, although sex-specific differences in gene accessibility and expression of cultured ND human islets predominantly affect sex chromosome genes, major differences in autosomal gene expression between sexes appear during the transition to T2D and which highlight mitochondrial failure in female ß cells.
RESUMEN
Salt affected cotton rhizospheric soil was explored for multi-stress resistance microbes to obtain 46 rhizobacteria. Of these, seven strains strongly inhibited the growth of phytopathogenic fungus Rhizoctonia solani by virtue of antifungal compound 2,4-diacetylphloroglucinol (DAPG) production. These seven strains demonstrated an array of plant growth-promoting activities as follows: (i) production of indole-3-acetic acid, ammonia, siderophore; (ii) solubilisation of phosphate, while two isolates showed Zn solubilisation. The phenetic and 16S ribotyping revealed affiliation of all the isolates to Pseudomonas guariconensis and presence of phlD gene marker for DAPG production. Among the seven isolates, strain VDA8 showed the highest DAPG production (0.16 µg ml-1) in liquid synthetic medium under aerobic conditions at 28 °C. Furthermore, sucrose, peptone, sodium hydrogen phosphate, ZnSO4, pH 8.0, and NaCl (1%) were observed as the best carbon, nitrogen, phosphate, trace element, pH, and salt concentration, respectively for maximum production of DAPG by strain VDA8 (3.62 ± 0.04 µg ml-1). The strain VDA8 was further assessed for wheat (Triticum aestivum) growth promotion by seed biopriming under laboratory (plate assay) and field condition in alkaline saline soil with pH 8.5. The field scale (324 m2) trials demonstrated 28.6% enhanced grain production compared to control demonstrating the newly isolated Pseudomonas sp. as multi-potent bioinoculant.
RESUMEN
The anatomy of the edentulous posterior maxilla and maxillary sinus possess unique challenges in implant dentistry. The purpose of this study was to assess maxillary sinus membrane thickness (MT) and lateral wall thickness (LWT) in different facial index profiles and to describe the clinical implications. A retrospective image analysis of 75 CBCT scans was done, which yielded a total of 150 sinus images. The facial index was calculated as per the formula given in the text and grouped as euryprosopic, mesoprosopic and leptoprosopic. The images obtained were of 36 women (48%) and 39 men (52%), with maximum subjects in 30-39 years age group. MT and LWT were measured at three different points on the radiograph at every 3mm from the base of the sinus floor in premolar and molar regions of each image. Results showed females had significant differences from males in LWT in both premolar and molar regions (p = 0.018 and 0.032 respectively). Subjects in 40-49 years of age had significant differences (p = 0.021) in MT in premolar region only. Also, difference in MT in premolar and molar regions were also statistically significant. Lastly, the present study did not find any statistically significant difference in MT and LWT in all three facial indices groups. It can be concluded that different facial indices have no positive correlation with maxillary sinus membrane thickness and lateral wall thickness. Hence, surgical complications are avoidable with proper detailed knowledge and appropriate identification of the anatomic structures characteristic to the maxillary sinus.

(NHC)âE coordination interactions were known where NHC is an N-heterocyclic carbene, and E is a main group element (B, C, N, Si, P). Recently, it was suggested that compounds with (NHC)âS coordination chemistry are also possible. This work reports quantum chemical analysis and synthesis of (NHC)âS-R(+) complexes in which benzothiazol-2-ylidene acts as a ligand. A Density functional study established that (NHC)âS interaction can best be described as a coordination interaction. Synthetic efforts were made, initially, to generate divalent sulfur compounds containing benzothiazole substituents. N-alkylation of the heterocyclic ring in these sulfides using methyl triflate led to the generation of the desired products with (NHC)âS coordination chemistry, which involves the inâ situ generation of NHC ring ligands. The observed changes in the 13C NMR spectra, before and after methylation, confirmed the change in the electronic character of the C-S bond from a covalent character to a coordination character.

RESUMEN
The relationship between ammonia and liver-related complications (LRCs) in acute-on-chronic liver failure (ACLF) patients is not clearly established. This study aimed to evaluate the association between ammonia levels and LRCs in patients with ACLF. The study also evaluated the ability of ammonia in predicting mortality and progression of LRCs. The study prospectively recruited ACLF patients based on the APASL definition from the ACLF Research Consortium (AARC) from 2009 to 2019. LRCs were a composite endpoint of bacterial infection, overt hepatic encephalopathy (HE), and ascites. A total of 3871 cases were screened. Of these, 701 ACLF patients were enrolled. Patients with LRCs had significantly higher ammonia levels than those without. Ammonia was significantly higher in patients with overt HE and ascites, but not in those with bacterial infection. Multivariate analysis found that ammonia was associated with LRCs. Additionally, baseline arterial ammonia was an independent predictor of 30-day mortality, but it was not associated with the development of new LRCs within 30 days. In summary, baseline arterial ammonia levels are associated with 30-day mortality and LRCs, mainly overt HE and ascites in ACLF patients.

Gingival overgrowth, localized or generalized, is one of the leading causes of poor maintenance of oral hygiene. Excision of growth using laser should be the choice of treatment because laser helps maintain a blood-free surgical site during treatment and provides more patient comfort during and after the procedure. Lasers are commonly employed in many different applications, including scaling, root planning, cavity preparation, and excision of soft tissue growths in surgery. Laser therapy offers numerous benefits over traditional methods of treatment. These benefits have led to the growing use of lasers as dental treatment options in a variety of dental fields. In this case report, we are presenting a case of excision of localized gingival growth using a laser. Postoperative healing and maintenance of oral health were satisfied after laser surgery.
RESUMEN
Diagnostic imaging is crucial in assessing dental implant patients. The height, width, and shape of the bone are precisely depicted and measured by these tests, which help pinpoint the locations of significant anatomical structures adjacent to the implant placement sites. The type of implant to be utilized, the positioning of the remaining dentition, and the degree to which bone quality or quantity is in question all play a role in determining the radiologic approach that is most suited for a given patient. This review is an update on the current knowledge in the field of radiographic evaluation in implant placement. Considering the radiation exposure and the expense of each test, it is important to carefully determine whether pre-implant imaging is acceptable in each situation. Although multislice computed tomography is the gold standard from the authors' perspective, not every implant situation can justify such a test.
