Aim And Objective: The purpose of the study was to compare the efficiency of modified conventional root canal shaping technique versus conventional shaping technique in primary teeth.
Materials And Methods: A total of 184 primary root canals (2 groups of 92 canals each) with two-thirds of root length were selected and randomly allocated into two different shaping techniques, i.e., Group I: conventional root canal shaping technique, Group II: modified root canal shaping technique. The quality of obturation (Coll and Sadrain, 1996) and presence or absences of voids were assessed by using radiographs. The recorded data was statistically analyzed.
Results: Significant difference was seen between conventional and modified conventional techniques in underfilled and optimally filled canals.
Conclusion: This modified cleaning and shaping technique can be considered as alternative to conventional instrumentation technique, as it improves quality of obturation and decreases the number of voids.

Riverine physical and chemical characteristics are influencing ecosystem integrity while shaping and impacting species richness and diversity. Changes in these factors could potentially influence community structuring through competition, predation and localised species extinctions. In this study, eight sampling sites over multiple seasons were assessed along the streams draining the City of Nelspruit, South Africa, to examine river health based on water and sediment quality, while using macroinvertebrates as bioindicators for pollution.

Hox genes have been investigated in various Arthropod species, resulting in the identification of ten Hox genes, organized in a colinear arrangement within the genome. Among arthropods, crustaceans exhibit a remarkable diversity of body shapes, which are associated with a variety of egg types, embryonic development patterns, and importantly, with the modulation of Hox genes to specify the identity of body segments along the antero-posterior axis of the embryo. Although there are more than 52,000 species of crustaceans described, their genomic resources are relatively limited, making it challenging to employ several molecular tools for studying embryonic development.

Background: Hypertension is common in patients with heart failure with mildly reduced or preserved ejection fraction (HFmrEF/HFpEF), and current guidelines recommend treating systolic blood pressure (SBP) to a target <130 mm Hg. However, data supporting treatment to this target are limited. Additionally, pulse pressure (PP), a marker of aortic stiffness, has been associated with increased risk of cardiovascular events, but its prognostic impact in HFpEF has not been extensively studied.

Introduction: Eating disorders are characterized by maladaptive eating behaviors and preoccupations around body shape, weight, and eating. The serotonin system has been among the most widely studied neurobiological factors in relation to eating disorders. Recent research also highlighted the role of oxytocin.

With the advancement of high harmonic generation and X-ray free-electron lasers (XFELs) to the attosecond domain, the studies of the ultrafast electron and spin dynamics became possible. Yet, the methods for efficient control and measurement of the quantum state are to be further developed. In this publication, we propose using magnetic X-ray scattering (MXS) for resolving the molecular spin-state dynamics and establish a complete protocol to simulate MXS diffraction patterns in molecules with ab initio quantum chemistry based on the multiconfigurational method.
