Long‐term outcomes of microsurgical interdental papilla reconstruction: 13‐year and 18‐year case follow‐ups

Clinical Advances in Periodontics, EarlyView.
Abstract Background Loss of the interdental papilla compromises esthetics, speech, and hygiene, significantly affecting quality of life and psychological well‐being. Reconstruction has long been considered unpredictable, particularly in Cairo RT3 cases with advanced interproximal bone loss.

Bhopal, its consequences and American international law in transnational litigation [PDF]

, 1983
In December 1984 poisonous gas leaked out from the Bopal plant in India. Some 1700 people were killed and more than 200.000 people injured. The accident led to criminal proceedings under Indian law.

Simplified SPAL technique to provide adequate peri‐implant phenotype: A pilot study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Correction of peri‐implant bone dehiscence (PIBD) and optimization of the peri‐implant soft‐tissue phenotype are critical for long‐term peri‐implant tissues stability. A simplified, one‐stage, transmucosal variant of the subperiosteal peri‐implant augmented layer (sSPAL) technique was appraised and evaluated.

Connective tissue graft wall technique for mandibular Class II furcation defects: Two case reports

Clinical Advances in Periodontics, EarlyView.
Abstract Background Furcation involvement (FI) represents one of the most challenging conditions in periodontal therapy due to limited accessibility and the progressive interradicular attachment loss that compromises long‐term tooth stability. Deep periodontal pockets in molars and premolars often present as combined defects, including horizontal FI ...

Bimanual instrument suturing technique for periodontal and implant microsurgery: A technical note

Clinical Advances in Periodontics, EarlyView.
Abstract Background In the traditional suturing technique, the dominant hand (DH) holds a needle holder, and the non‐dominant hand (NH) performs manual ties without the aid of an instrument. In periodontal and implant microsurgery, finer sutures and needles, e.g., 7‐0 in International Organization for Standardization units, are used, which could be ...

Holocene 231Pa/230Th ratios, Uranium isotopes and biogenic Opal concentrations from four North Atlantic sediment cores

To investigate the variability of the Atlantic Meridional Overturning Circulation (AMOC) during the Holocene in the North Atlantic, we analyzed radioisotopes (230Th, 231Pa, 232Th, 234U, and 238U) in sediment samples from four core sites (ODP 172-1063 ...

Multivalent RNA‐Cleaving Agents on a Cubic Octameric Silsesquioxane Core

Chemistry – A European Journal, EarlyView.
RNA‐cleaving agents on a cubic octameric silsesquioxane core were synthesized and characterized. Several catalytic systems of these structures were screened using hexaribonucleotide models. The best systems were then further used to study their catalytic efficiency in cleaving a HER2 mRNA model sequence. The induced cleavage sites were also determined.

231Pa/230Th ratios, Uranium isotopes and biogenic Opal concentrations of five North Atlantic sediment cores

To examine the influence of the Atlantic Meridional Overturning Circulation (AMOC) on 231Pa/230Th in the North Atlantic from the Last Glacial Maximum (LGM) to the Holocene, we analyzed radioisotopes (230Th, 231Pa, 232Th, 234U, and 238U) in sediment ...

Rapid Synthesis of Weinreb Amides via Titanium‐Mediated Direct Amidation at Room Temperature

European Journal of Organic Chemistry, EarlyView.
Rapid titanium‐mediated direct amidation enables the room‐temperature synthesis of Weinreb amides directly from carboxylic acids under mild conditions. The operationally simple protocol delivers a broad substrate scope in good to excellent yields, including challenging fluorinated substrates, without the need for conventional coupling reagents ...
