Novel Technique for Fracture Fixation of the Patella Following Unicondylar Knee Replacement: A Clinical Case Report.

Introduction: Unicondylar knee replacement (UKR) is a surgical procedure frequently performed to treat medial compartment osteoarthritis, offering advantages such as quicker recovery and preservation of knee kinematics. However, complications can arise, including periprosthetic fractures. Patella fractures in the context of UKR are particularly challenging due to the presence of the implant.

Silanediol-Bay-Bridge Rigidified Axially Chiral Perylene Bisimide.

Chiral organic molecules with a complementing π-structure are highly desired to obtain materials with good semiconducting properties and pronounced chirality effects in the visible region. Herein, we introduce a novel design strategy to achieve an axially chiral and rigid perylene bisimide (PBI) dye by attaching the chirality-inducing 2,2'-biphenoxy moiety at one side of the bay area and the rigidity-inducing di--butylsilanediol bridge on the other side. This yielded a new bay-functionalized PBI derivative carrying the combination of a highly rigid and, simultaneously, an axially chiral perylene core.

Clinical, Hematological, and Biochemical Profile in Seropositive Dengue Cases at a Tertiary Care Hospital in Nepal.

Dengue virus infection is a major source of morbidity and mortality in the majority of tropical and subtropical nations. In Nepal, the first case of dengue was reported in 2004, followed by numerous outbreaks exerting a critical impact on public health. This study aims to describe the clinical and laboratory characteristics of dengue patients visiting a tertiary care hospital to see the trend of presentation.

Upconverting Luminescent MOF for Highly Sensitive Dual-Mode Recognition of Synthetic Dyes.

Lanthanide-based luminescent materials hold promise in sensing applications due to their distinct optical properties. Though advancements in lanthanide-based metal-organic frameworks (MOFs) have enhanced downshifting luminescence, achieving upconversion remains challenging. In this effort, we prepared upconverting ytterbium-doped europium MOFs (%Yb-EuMOFs; = 10, 20, and 30) via the solvothermal method using 2,6-naphthalenedicarboxylic acid (NDC) as an organic linker.
