Pulp sensibility responses following complete and partial pulpotomy in mature permanent molars with carious pulpal exposure and symptomatic irreversible pulpitis: Analysis of pooled data from three randomized clinical trials.

Aim: The objective of pulpotomy is to preserve the pulp vitality. However, the assessment of pulpal status following pulpotomy is often overlooked. This retrospective analysis aimed to compare the pulp responses to EPT (Electric pulp test) and cold test in mature permanent molars that have undergone either complete pulpotomy (CP) or partial pulpotomy (PP) for managing carious pulpal exposure and symptomatic irreversible pulpitis (SIP) and completed 12 months follow-up.

Smile Reestablished-Predictable Management of Complicated Crown-root Fracture through Surgical Extrusion with and without 180° Rotation: A Case Report.

Aim And Background: The management of crown-root fractures poses significant uncertainty and involves meticulous evaluation of the tooth and supporting structures. The uncertain prognosis associated with crown-root fractures necessitates periodic evaluation.

Case Description: A 15-year-old female presenting with crown-root fracture of the permanent left maxillary incisors was treated by surgical extrusion with rotation for the central incisor, while the lateral incisor was coronally extruded by 2 mm.

Host and pathogen genetic diversity shape vaccine-mediated protection to .

To investigate how host and pathogen diversity govern immunity against (Mtb), we performed a large-scale screen of vaccine-mediated protection against aerosol Mtb infection using three inbred mouse strains [C57BL/6 (B6), C3HeB/FeJ (C3H), Balb/c x 129/SvJ (C129F1)] and three Mtb strains (H37Rv, CDC1551, SA161) representing two lineages and distinct virulence properties. We compared three protective modalities, all of which involve inoculation with live mycobacteria: Bacillus Calmette-Guérin (BCG), the only approved TB vaccine, delivered either subcutaneously or intravenously, and concomitant Mtb infection (CoMtb), a model of pre-existing immunity in which a low-level Mtb infection is established in the cervical lymph node following intradermal inoculation. We examined lung bacterial burdens at early (Day 28) and late (Day 98) time points after aerosol Mtb challenge and histopathology at Day 98.

Activity-dependent FosB gene expression negatively regulates mast cell functions.

Mast cells are innate immune cells that play a crucial role in numerous physiological processes across tissues by releasing pre-stored and newly synthesized mediators in response to stimuli, an activity largely driven by changes in gene expression. Given their widespread influence, dysfunction in mast cells can contribute to a variety of pathologies including allergies, long COVID, and autoimmune and neuroinflammatory disorders. Despite this, the specific transcriptional mechanisms that control mast cell mediator release remain poorly understood, significantly hindering the development of effective therapeutic strategies.

Benchmarking of a microgel-reinforced hydrogel-based aqueous lubricant against commercial saliva substitutes.

Xerostomia, the subjective sensation of 'dry mouth' affecting at least 1 in 10 adults, predominantly elders, increases life-threatening infections, adversely impacting nutritional status and quality of life. A patented, microgel-reinforced hydrogel-based aqueous lubricant, prepared using either dairy or plant-based proteins, has been demonstrated to offer substantially enhanced lubricity comparable to real human saliva in in vitro experiments. Herein, we present the benchmarking of in vitro lubrication performance of this aqueous lubricant, both in its dairy and vegan formulation against a range of widely available and employed commercial saliva substitutes, latter classified based on their shear rheology into "liquids", "viscous liquids" and "gels", and also had varying extensional properties.

Oxidative stress and DNA damage in newborns born to mothers with hyperglycemia - a prospective cohort study.

Background: Hyperglycemic mothers have increased oxidative stress during pregnancy, which can adversely affect the outcome in their neonates.

Objectives: To measure the oxidative stress and DNA damage in newborns born to mothers with hyperglycemia and correlate their immediate outcome with the amount of oxidative stress and DNA damage.

Methods: This prospective cohort study conducted in a tertiary care teaching hospital, South India included three groups - newborns born to pregestational diabetic mothers, gestational diabetic mothers, and euglycemic mothers with 24 newborns in each.

Factors associated with conversion of long-term non-progressors to progressors: a prospective study of HIV perinatally infected paediatric survivors.

Background & Objectives: Survival pattern among children infected with the human immune deficiency virus (HIV) follows a bimodel distribution. Some children survive beyond 9 years age and are known as long term survivors (LTS) while others had a more rapid course to death during the first few years of life. In the LTS group of children, two sub-populations have emerged, the long term non-progressors (LTNP) who have remained asymptomatic over a period of years and those who have survived despite clinical and laboratory evidence of disease progression, the long term progressors (LTP).

Interfacial study of class II hydrophobin and its mixtures with milk proteins: relationship to bubble stability.

Class II hydrophobin (HFBII) is a very promising ingredient for improving food foam stability. Pure HFBII-stabilized bubbles exhibited exceptional stability to disproportionation (dissolution) but were not stable to bubble coalescence induced by a pressure drop. Bubbles stabilized by mixtures of HFBII + sodium caseinate (SC) or β-lactoglobulin (BL) showed decreased shrinkage rates compared to pure SC or BL and improved the stability to pressure-drop-induced coalescence.

Preparation and characterization of the foam-stabilizing properties of cellulose-ethyl cellulose complexes for use in foods.

Surface active cellulose particles have been prepared for use as foam stabilizing agents in foods. Various sources of cellulose were broken down by combinations of milling, acid dissolution and treatment with cellulase. The most efficient and simple method was hammer and freezer milling of dry crystalline α-cellulose (Tencel).

Influence of piperine on ibuprofen induced antinociception and its pharmacokinetics.

Piperine (CAS 94-62-2), an alkaloid obtained from Piper nigrum and P. longum, is a known inhibitor of various enzymes (CYP isozymes) responsible for biotransformation of drugs. By inhibiting the metabolism of drugs, piperine improves the bioavailability of drugs.
